2010-2011 AEMREXCUTIVE SUMMARYWambo Coal Pty Limited (WCPL) continued to operate in accordance with its Mining Operations Plans (MOP),Development Consents, Environmental Protection Licence (EPL) and all other approvals during the 2010-2011reporting period.WCPL reported one notifiable environmental incident during the reporting period in relation to an overpressureexceedance from a blast in February 2011.All environmental monitoring undertaken during the reporting period was in accordance with DA 305-7-2003, DA17-8-2004, Environmental Protection Licence (EPL) No.529 and approved management plans.Due to delays in Open Cut operations, WCPL completed no rehabilitation during the reporting period. However,remedial rehabilitation on the North Wambo Creek Diversion (NWCD) was completed, and rehabilitation of NorthEast Tailings Dam (NETD) continued, during the reporting period.The WCPL Open Cut moved a total of 27,583,359 bank cubic metres (bcm) of prime overburden to allow theextraction of 4.015 million tonnes (Mt) of run of mine (ROM) coal during 2010-2011.The WCPL Underground operation extracted a total 4.715 Mt of ROM coal during the 2010-2011 reporting period.A total of 5.68 Mt of product coal was produced by Wambo during the 2010-2011 reporting period.All coal produced from WCPL was railed via the WCPL rail spur and rail line to the Port of Newcastle for export.There was no change in production methods during this reporting period.At the current rates of production and assuming no further mining approvals, the Open Cut and Underground minehas a remaining life of approximately 5 years and 4 years respectively.WCPL received a total of thirty five community complaints during the reporting period.Page ix

2010-2011 AEMR1.0 Introduction1.1 ScopeThis Annual Environmental Management Report(AEMR) details the environmental performance ofWambo Coal Pty Limited (WCPL) mining,construction and rail activities for the period from 1July 2010 to 30 June 2011. WCPL is required toprepare and submit an AEMR in accordance withthe Department of Trade and Investment, RegionalInfrastructure and Services (DTIRIS), Guidelinesand Format for Preparation of an AnnualEnvironmental Management Report Version 3,January 2006.The preparation of this AEMR, also satisfy’s theAnnual Review requirements under DevelopmentApplications (DA) 305-7-2003 and 177-8-2004.Table 1.0 displays each Annual Review requirementand where the requirements are addressed withinthe AEMR. The AEMR also satisfy’s theEnvironment Protection and BiodiversityConservation (EPBC) Act, 1994 approvalEPBC/1138, and the approved SubsidenceManagement Plan (SMP) for Longwalls (LW) 1-6.An aerial photo and locality plan for the mine isshown in Figure 1.1.1.2 BackgroundWCPL is owned by Peabody Energy Australia PtyLimited (75%) and Sumiseki Materials Co, Ltd (25%- Net profit B class shares). WCPL is an Open Cutand Underground mining operation locatedapproximately 15 kilometres (km) west of Singletonnear the locality of Warkworth. It is bounded byWollombi Brook to the east, coal mining operationsto the north, grazing land to the south and northwest and the Wollemi National Park to the west andsouth west.WCPL was granted development consent by PatrickPlains Shire Council in 1969 with Open Cut andUnderground mining commencing shortly after.Subsequent development consents issued in 1972,1974 and 1977 covered a range of early Open Cutand Underground operations. Singleton ShireCouncil (SSC) approved extensions to miningoperations, construction activities and modificationsto road haulage rates in the period between 1980and 1991.In July 1991, a Development Application (DA) waslodged with SSC seeking approval for the expansionof Open Cut and Underground mining activities andthe consolidation of earlier development consents.Development consent was granted in February1992.The Homestead Underground Mine commenced in1979 and operated until 1999. In 2003 the mineentries were sealed.The Wollemi Underground Mine commencedproduction in 1997 and was placed under care andmaintenance in October 2002 after the availablelongwall reserves were exhausted.Open Cut operations were suspended betweenMarch 1999 and August 2001. Following theclosure of the Wollemi Underground Mine, OpenCut operations were expanded to maintain anoverall production rate of 3 million tonnes perannum (Mtpa) of product coal. Development of theNorth Wambo Underground Mine (the Underground)commenced in November 2005, with longwalloperations commencing in October 2007.Coal from the Open Cut and the Undergroundoperations is washed at the Coal Handling andPreparation Plant (CHPP). Until June 2006 productcoal was transported by highway rated trucks viathe Golden Highway to the Mount Thorley CoalLoader for rail transport to the Port of Newcastle.The construction and commissioning of the WCPLRail Development (WRD) in May 2006, whichincludes the rail line from Mount Thorley and WCPLrail spur and coal terminal, allows the direct railtransportation of all product coal from WCPL to thePort of Newcastle.United Colliery (United), owned by Xstrata CoalNSW, ceased longwall underground mining in theArrowfield Seam during the last reporting period.United underground mining previously occurredbeneath sections of WCPL’s Open Cut andUnderground operations. The last of United’s coalwas loaded by rail on 27 May 2010. United arecurrently under care and maintenance, whilstundertaking further exploration activities withinA444.Page 1

2010-2011 AEMR1.3 Consents, Leases andLicences1.3.1 Development ConsentsMining and rail activities at WCPL operate undervarious development consents granted by the NSWDepartment of Planning & Infrastructure (DoPI),formally the Department of Planning (DoP), andSSC. The continued development of open cut andunderground mining activities commenced underDA 305-7-2003 in November 2004. The constructionof the rail spur, rail loop and train loadout areacommenced under DA 177-8-2004 in January 2005.1.3.2 Mining Leases andAuthorisationsWCPL’s current mining leases and authorisationsare listed below in Table 1.2 and shown in Figure1.2.Table 1.0 outlines the Annual Reportingrequirements from DA305-7-2003 and DA177-8-2004 and where the requirement is addressed in theAEMR. Table 1.1 outlines the active developmentconsents applicable to WCPL.During the reporting period WCPL sought to modifyDA 305-7-2003 in accordance with Section 75(W) ofthe Environmental Planning and Assessment Act1979 (EP&A Act), to prepare an Extraction Plan forplanned longwall mining activities. The 75(W)application to modify the consent was approved byDoPI in February 2011.An additional modification to DA 305-7-2003 inaccordance with Section 75(W) of the EP&A Actwas also lodged by WCPL towards the end of thereporting period. The proposed modificationconsists of an additional three longwall panels andunderground mine related surface facilities, whichwill be located to the north west of the existingapproved Underground mine. At the time ofpreparing the AEMR no decision had been made bythe DoPI, regarding this modification.During April 2011, an application to modify DA177-8-2004 in accordance with Section 75(W) of theEP&A Act was lodged by WCPL for theestablishment of a small locomotive refuellingstation adjacent to the WCPL rail loadout facility. Atthe time of preparing the AEMR, no decision hadbeen made by the DoPI regarding this modification.All other development consents, except DA 108/91granted by SSC, were surrendered by WCPL inNovember 2005.Page 2

2010-2011 AEMR1.3.3 Environmental ProtectionLicenceWCPL operates under Environmental ProtectionLicence 529 (EPL 529), issued by the NSW Officeof Environment & Heritage (OEH), formerly theDepartment of Environment, Climate Change andWater (DECCW), under the authority of theProtection of the Environment Operations Act 1997.EPL 529 also covers WCPL’s activities at the mineand rail spur.During the reporting period, the OEH varied EPL529 to incorporate two Pollution ReductionPrograms (PRP). The PRP’s included providing theOEH with a Revised Site Water Balance Report,and a Groundwater Trend Report. Both reports werecompleted by WCPL and submitted to the OEH inFebruary 2011.1.3.4 NPW Act ApprovalsWCPL holds a permit under the National Parks andWildlife Act 1974 (NPW Act), for the salvage andimpact on Aboriginal heritage sites prior to grounddisturbance. Consent number #2222 was issuedunder Section 87 and Section 90 of the NPW Act onthe 20 June 2005. In consultation with the OEH andlocal Aboriginal groups, the OEH granted approvalto extend the permit for an additional 5 years,expiring on the 19 June 2015.Consent number #2085 was issued under Section90 of the NPW Act on 14 December 2004 for thesalvage of Aboriginal artefacts along the WamboRail Development. Salvage works for the WamboRail Development were completed and reported inthe 2005-2006 reporting period. There have beenno further salvage works under consent number#2085. Consent #2085 expired in January 2007.For further information regarding Aboriginal Heritageand salvage works undertaken during this reportingperiod, please refer to Section 3.13.1.For further details regarding Permit #3130 for Careand Control of Aboriginal Objects, previouslysalvaged under Section 87/90 permits, please referto Section 3.13. 1.Details of the current water licenses for WCPL arepresented in Table 1.3. The location of theselicensed facilities is shown in Figure 1.3.1.3.6 Mining Operations PlanIn accordance with the Mining Act 1992, WCPLhave prepared and submitted two MiningOperations Plans (MOP’s) for the Open Cut andUnderground.All open cut mining activities were carried outgenerally in accordance with the approved OpenCut MOP. All underground mining activities werecarried out generally in accordance with theapproved Underground MOP.During the last reporting period a new Open CutMOP was approved by the DTIRIS, formerly theIndustry & Investment NSW (I&I NSW) on the 29June 2010. The new Open Cut MOP was preparedin accordance with the DTIRIS Guidelines andFormat for Preparation of Mining Operations PlanVersion 3, January 2006. WCPL consulted with theDTIRIS and provided information to the communitythroughout the development of the MOP. The MOPcovers all aspects of the Open Cut operationincluding mining, rehabilitation and tailingsmanagement, until the year 2016.WCPL sought an interim modification to the OpenCut MOP to raise a larger area of the Wombat dumpto RL160. The request to raise dump levels isconsistent with commitments made in the 2003 EIS.The DTIRIS approved the modification on the 20December 2010. WCPL are planning to apply for amodification to the Open Cut MOP during the nextreporting period, to address proposed operationalchanges.The MOP for the Underground was approved by theDTIRIS in November 2005 for the period November2005 to November 2012. This MOP applies tounderground mining operations and refers to theOpen Cut MOP where applicable. No modificationsto the Underground MOP were sought by WCPLduring the reporting period.1.3.5 Water LicencesWCPL currently holds water licences for a numberof bores, wells and pumps located across the minesite. There were no new water licenses issued bythe NSW Office of Water (NOW) during thereporting period.Page 9

2010-2011 AEMR2.0 Operations During theReporting Period2.1 ExplorationSurface exploration throughout the reporting periodconsisted of a total of 318 boreholes atapproximately 31,700 meters drilled. Explorationdrilling occurred were drilled in the followingareas; 233 x boreholes within A444 with a total of14,100 m drilled; 48 x boreholes within CL743 with a total of13,500 m drilled; 33 x boreholes within CL397 with a total of2,900 m drilled; and 4 x boreholes within EL7211 with a total of1,200 m drilled.Drilling is required to further define coal reserves,coal quantity and gas content of the Whybrow,Redbank Creek, Wambo and Whynot coal seams.All exploration boreholes were fully grouted uponcompletion.It is expected that exploration activities over thecoming twelve months will continue within A444,CL397, CCL743 and EL7211. WCPL is anticipatingdrilling approximately 180 boreholes (approximately50,000 m) during the next reporting period. A444was renewed during the reporting period inconjunction with United. EL7211 is planned forrenewal during next reporting period.2.2 Land PreparationIn accordance with the Open Cut MOP and DA 305-2003, all land clearing at WCPL is carried out underapproved management plans and procedures. Onesuch approved management plan is the Flora andFauna Management Plan (FFMP), which includes aVegetation Clearance Protocol (Figure 2.1). Inaccordance with the FFMP, a Surface DisturbancePermit (SDP) procedure and checklist has beendeveloped. The SDP requires the approval ofWCPL’s environmental department prior to anyclearing activities taking place. The SDP aims toidentify any environmental issues such as CulturalHeritage sites, flora and fauna communities, surfacedrainage, threatened species, and the identificationof any seed or timber resources that can besalvaged.management and salvage of timber resources,dependent on the characteristics of the vegetationto be cleared, and is determined on a case by casebasis.Nominally, a minimum of 100 millimetres (mm) oftopsoil is recovered from the surface prior to miningan area. The actual volume of topsoil recovered isdependent on the depth of insitu soil conditions (e.g.deeper in alluvial areas and shallower on ridgelines), and the quality of the material.Where possible, direct placement of stripped topsoilonto re-profiled areas is preferred to stockpiling, inorder to avoid rehandling and reduce the potentialfor further topsoil degradation or loss. However, dueto lack of available area, this was not possibleduring this reporting period. If a re-profiled surface isnot available, the topsoil is stockpiled. Thetreatment of the topsoil stockpiles is dependent onthe planned timeframe between construction anduse. If these stockpiles are to be left for longer thanthree months, they are generally shaped intoelongated mounds and seeded with pasture to keepthe soil fertile, stop weeds from growing and toreduce soil loss.Due to a change in dump plan for the RL 160 dump,approximately 14.2ha of previously rehabilitatedland was re-disturbed during the reporting period.The topsoil and established pasture vegetation wasrecovered from the re-disturbed area prior todumping.2.3 ConstructionCoal Handling Preparation PlantMajor works included the construction of a new 500tonne reject bin at the CHPP, which commenced atthe end of the reporting period. At the end of thereporting period, WCPL had completed the bulkearthworks including the drainage and accessroads. In addition, the main concrete slab and guidewalls were also completed for the new reject bin.The new reject bin is expected to be operational bythe end of 2011.In addition to the FFMP, WCPL have developed aTimber Management Plan (TMP). The TMP hasidentified a number of options regarding thePage 18

The upgradeincluded a new concrete pad for stockpiling smallamounts of coal spillage and an oil water separator.Administration AreaA new vehicle parking area adjacent to the Main CarParking area was completed in early 2011 toincrease the capacity for employee and contractorcar parking by approximately 80 vehicles.North Wambo UndergroundThere were a number of construction activities atthe Underground during the 2010-2011 reportingperiod, including: Completion of Homestead fan construction andcommissioning; Removal of NWU Inpit axial fan; Installation and commissioning of new inpitcentrifugal fan; Development of mains entries into homesteadopen cut pit; Construction of mains heading portals; Development of Maingate 6 portals; Extension of mains conveyor into HomesteadPit; Installation of MG6 conveyor system andgantry; and Installation of Homestead infrastructure such asawnings.Table 2.1 provides a summary of coal production forthe 2010-2011 reporting period. During thereporting period, a combined total of 8.730 (Mt) ofROM coal was mined, representing a 15.1%increase compared with the 2009-2010 reportingperiod.Open cut operations in the reporting period weregenerally in accordance with the Open Cut MOP.The provisional mine production schedule in theOpen Cut MOP for the 2010-2011 reporting periodallowed for approximately 4.1Mt ROM coal mined.The actual ROM coal for reporting period was 4.015Mt. Approximately 194,750.5m 3 of topsoil wasrecovered, whilst no topsoil was used forrehabilitation purposes. Approximately27,583,359bcm of overburden material wasremoved during the reporting period, almost 27%more than the previous AEMR period.Underground operations in the reporting periodwere generally in accordance with the UndergroundMOP. The provisional mine production schedule inthe Underground MOP for the 2010-2011 reportingperiod allowed for approximately 2.81Mt ROM coalmined. The actual ROM coal for reporting periodwas 4.715 Mt.2.4.2 Estimated Mine LifeCoal resources in the Colliery Holding and A444exploration area are approximately 648 Mt withgreater than 65.6% (425.43 Mt) of the resource atmeasured status. WCPL has approval to mine up to14.7 Mt per annum of ROM coal for 21 years from2004 within the Colliery Holding. This mining willtake place through the existing Open Cut operationsin the Whybrow, Redbank Creek, Wambo andWhynot seams and Underground mining in theWambo seam.New Homestead Ventilation FanPage 19

2010-2011 AEMR2.4.3 Underground OperationsWCPL’s North Wambo Underground (NWU) minesthe Wambo seam using continuous miners andlongwall mining methods. The first of eight longwallblocks (LW1) was completed in February 2009 andproduction commenced in the second longwall block(LW2) in March 2009. In December 2010, extractionof Longwall Panel 3 (LW3) was completed, withproduction of Longwall Panel 4 (LW4) commencingin January 2011. At the end of the reporting periodLW4 had retreated 1,950m. The completion of LW4is expected in October 2011. The Undergroundcontinues to operate seven days a week.In total 8 x 250m wide Longwall panels,approximately 3.8 km to 4 km in length will bedeveloped with the Longwall panels orientatedsouth-west to north-east. Longwall panels one tofive will be developed off main headings driven fromthe existing Bates North Open Cut highwall. Theremaining three panels will be developed by punchmining directly off the Homestead Pit Open Cuthighwall.WCPL primarily use Joy Mining Longwallequipment, including the Longwall operatingsystem. The Longwall panels are formed by drivingtwo sets of gateroads (the tailgate and maingateroads). Each gateroad requires two roadways(headings) to be driven parallel to each other (31 mapart). One of the roadways is used for personneland materials access and fresh air intake ventilationwhile the other is used for coal clearance and returnair ventilation. The roadways are developed usingtwo Joy 12CM30 continuous miners. Approximately10,349 m of roadway was developed in the 2010-2011 period with a total of 4,361 m of Longwallretreat.The headings are connected every 100 m by drivinga cut through from one heading to another. Thisforms pillars of coal along the length of thegateroad. The tailgate and maingate roads areseparated by the 250 m wide Longwall panel. Themaingate roads and tailgate roads are then linkedtogether by driving an installation road and bleederroad at the inbye end of the longwall panels.As the continuous miners develop the roadways,Run of Mine (ROM) coal is conveyed to a stockpilewith an approximate 70,000 tonne capacity. Whena sufficient stockpile is present, coal is loaded ontotrucks for transport to the CHPP. During the 2010-2011 reporting period, approximately 4.8 Mt of ROMcoal was produced.At the end of the reporting period the followingequipment was available for mining activities at theUnderground, including:2 x Joy 12CM29 Continuous miners;1 x Joy 12CM30 Continuous miner3 x electric shuttle cars with a 15 t payload;8 x Load Haul Dump (LHD) machines; 9 x personnel transporters SpecialisedMining Vehicles (SMV’s);Associated longwall equipment;146 Joy Roof Supports;2 x Joy 7LS2a Shearers;2 x BSL and AFC systems2 x Monorail system;2 x Pump sled; and2 x 5MVA TransformerThe old Wollemi Underground Mine was on careand maintenance throughout the reporting periodwith no coal being produced from this mine. The oldWollemi workshop, bathhouse and store facilitiespreviously used by the WCPL’s Undergroundoperations were decommissioned during October2008 due to the completion of the newadministration and bathhouse facilities. Planningwork was undertaken in this reporting period for thesealing of the Wollemi Mine and removal of the oldbuildings.2.4.4 Open Cut OperationsDowner EDI Mining are contracted to undertakeOpen Cut mining operations at WCPL. Open cutmining is divided into pits known as the Bates Pit,Bates South Pit, Montrose Pit and the HomesteadPit. The Bates Pit, Bates South Pit and theMontrose Pit are adjoining and linked via a miningcorridor. The Homestead Pit is a separate miningarea.Operations during the reporting period occurred inthe Bates Pit, Bates South Pit, the corridor ofMontrose Pit and the Homestead Pit. The currentOpen Cut workings are presented in Figure 2.2.Mining of the Open Cut commences with theremoval of vegetation and topsoil as described inSection 2.2. Following land preparation,excavators and trucks remove any weatheredmaterial as a “free dig” operation. The weatheredmaterial that can be free dug ranges from one metreto ten metres in thickness. The remainingoverburden is drilled, blasted and removed utilisingPage 22

2010-2011 AEMRthe excavators and rear dump haul trucks touncover the coal.The exposed coal is mined using excavators andloaded into haul trucks. The intervening clay bands,when thick enough, are excavated and loaded outseparately for disposal in pit to avoid complicationsin the coal washing process. The coal is minedwithout blasting. The majority of ROM coal isdelivered directly from the Open Cut to the ROMdump hopper using haul trucks, with the balancetemporarily stockpiled on the ROM coal stockpilepad. Mining is based on a shift roster of two 12.5hour shifts per day. Table 2.2 shows annual ROMproduction levels from Open Cut mining at WCPLfor the past 14 years.Table 2.2 – Annual Open Cut ROM Production LevelsYearCoal(ROMtonnes)Overburden(Bank CubicMetres)Ratio1997-1998 1,232,658 7,322,227 6.2:11998-1999 482,002 1,684,484 3.5:11999-2000 13,700 41,800 3.0:12000-2001 0 0 -2001-2002 922,613 8,025,081 8.7:1*2002-2003 3,671,000 22,550,000 6.1:12003-2004 4,220,000 23,530,000 5.6:12004-2005 4,186,000 23,240,000 5.6:12005-2006 5,424,000 30,620,000 5.6:12006-2007 5,790,000 35,150,783 6.1:12007-2008 4,245,395 27,854,967 6.6:12008-2009 3,386,614 23,886,024 7.1:12009-2010 2,751,000 19,866,651 7.2:12010-2011 4,015,000 27,583,359 6.9:1* Anomalously high ratio due to reopening and expansion.During the reporting period, Open Cut coal wasprimarily mined from the Whybrow, Redbank Creek,Wambo and Whynot seams. Backfilling of theWombat Pit continued, reducing the need for out ofpit dump space. At the end of the reporting periodthe following equipment was utilised to undertakeOpen Cut mining activities:2 x Cat 16H Grader1 x Cat 24H Grader2 x Cat 773 Service Truck1 x Cat 773D Water Cart2 x Cat 773C Water Cart7 x Cat 785B Dump Truck9 x Cat 785C Dump Truck6 x Cat 789C Dump Truck2 x Komatsu 830E Dump Truck10 x Komatsu 930E Dump Truck6 x Komatsu HD785 Dump Truck1 x Cat 972H Loader1 x Cat 992D Loader1 x Cat 992G Wheel Loader1 x Cat 994 Wheel Loader1 x Cat D10R Dozer3 x Cat D10T Dozer1 x Cat D11N Dozer7 x Cat D11R Dozer1 x Hitachi EX2500 Excavator1 x Hitachi EX3600 Excavator3 x Komatsu PC5500 Excavator1 x Komatsu PC250-6 Excavator1 x Liebherr R994B Excavator2.5 Coal Handling andPreparationThe coal handling process is illustrated in Figure2.3. Coal from the Open Cut and Undergroundoperations is transferred to the CHPP via haultrucks on internal haul roads. Coal is tipped directlyinto the 400 tonne ROM bin or stockpiled adjacentto the ROM bin and subsequently loaded into theROM crusher using a front-end loader, as required.Three stages are used to crush the ROM coal. Thecrushed coal passes into the CHPP, then into twoseparate Modules which contain dense mediumcyclone coarse coal circuits. These operate inparallel with a teetered bed separator for thebeneficiation of fine material in Module 2, andspirals in Module 1.All clean coal is conveyed to the clean coalstockpile. Four underground reclaim points feedcoal from the clean coal stockpile onto the reclaimconveyor (The fourth reclaim point was previouslyused to feed the clean coal from United.) Thereclaim conveyor transfers coal onto the load-outconveyor, which conveys to the train load-out bin.The WCPL train loading system is designed to loadtrains at a rate of 4,500 tonnes per hour (tph).Details of the amount of coal transported by railfrom the rail load facility are presented in Appendix1. All coal produced by WCPL was transported byrail during the reporting period. During the reportingperiod the CHPP processed a total of 8.730 MtROM coal. The average coal recovery was 65%.Page 23

2010-2011 AEMRhydrocarbon spill response as part of the siteintroduction program. As of the 1 January 2009, thewaste from the Open Cut workshop is nowmanaged as part of the TWMS. The TWMS wasbeen reviewed during the reporting period and willgo out to tender during the next reporting period.2.6.1 Sewage Treatment andDisposalSewage from the various areas of mining operationis treated in four on site treatment systems asfollows:CHPP Bathhouse – septic tank system whichfeeds to a transpiration area;CHPP Control Room – biocycle system;Administration Buildings – effluent systempumps to a transpiration dam located to thewest of the complex; andNorth Wambo Underground Portal – effluentcollection tank.The Wollemi Bathhouse and Facilities are no longerin use. The effluent treatment system is notoperational and these facilities have now beendecommissioned.Effluent treatment systems are inspected andmaintained on a periodic basis to ensure effectiveoperation. All effluent collected from theUnderground portal is disposed of by a licensedcontractor and records are maintained on site.2.6.2 Rubbish DisposalBulk garbage bins for each waste stream arelocated around site. These bins are collected andmanaged on a regular basis by a licensed wastecontractor. For details of waste disposed andrecycled during the reporting period please refer toTable 2.4.2.6.3 Oily Waste DisposalWaste oils from the site are collected, stored andare removed by a licensed waste contractor on aperiodic basis for reprocessing and reuse. Fordetails of waste oil disposal during the reportingperiod please refer to Table 2.4.A mix of passive and active oily water separatorsystems for the separation of hydrocarbons fromoily water runoff, are located across the siteincluding: the rail load out,Underground portal area, andOpen Cut workshop and wash down area.Licensed waste contractors remove collected wasteoil from the separators on a regular basis. Routineinspections are carried out on all systems to ensurethat there are no blockages or overflows. Records ofall waste disposals are kept on site.2.7 ROM and Product CoalStockpilesA 70,000 tonne ROM coal stockpile for undergroundcoal is located near the Underground portal level,just east of the Underground entrance.Underground coal is conveyed to the UndergroundROM stockpile from the portal entrance byConveyor CV01.Coal is transported from the Open Cut andUnderground ROM Stockpile via truck and eithertipped directly into the 400 tonne ROM hopper orstockpiled adjacent to the ROM bin. The ROMstockpile area is approximately 200m x 200m with aROM coal storage capacity of approximately250,000 tonnes.The capacity of WCPL clean coal stockpile is500,000 tonnes.2.8 Water ManagementThe water management system at WCPL comprisesclean water (imported water from the Hunter Riveror Wollombi Brook), mine water (collected run-offfrom disturbed catchments or recycled water fromthe CHPP) and fresh water (either imported from thetown supply or collected rainwater). The watermanagement system is illustrated in Figures 2.4and 2.5 and major storages are presented in Table2.3.A network of storages and drains has beenestablished to capture runoff from mine watercatchment areas. Runoff from areas disturbed bymining (including the CHPP and associatedindustrial areas) is collected in Open Cut voids andother mine water storages. These storages areused as priority water sources for the CHPP anddust suppression. Runoff from haul roads is treatedin sediment dams or diverted to mine waterstorages.CHPP tailings are discharged to the Hunter Pittailings dam. Water that is liberated from the settledtailings filters through spoil at the southern end ofthe dam and reports to the North Homestead Pit.Water is reticulated from this pit back to the CHPP.Page 27

2010-2011 AEMRRunoff from rehabilitated and establishingrevegetated mine areas is directed to sedimentdams. These are either allowed to drain to localdrainages or directed to mine water storages,depending upon the water quality.An extensive reticulation system has beendeveloped to: transfer water between Open Cut andUnderground operations and mine waterstorages;such as upgrades to pump-out lines from theBates Pit area and movement towards anintegrated water management system; andthe automation of major pump installationsacross the site was fine-tuned and overallmaintenance of pumping infrastructurecontinued.source water from Wollombi Brook and theHunter River;facilitate controlled releases to Wollombi Brook;and(until the end of 2009) provided water to theadjacent United Collieries operation.The available water sources and undergroundstorage capacity for mine water have providedWCPL with flexibility to manage its water system.During the reporting period the main watermanagement related activities included:reviewing the site water balance for the shortand medium term, taking into account the newMOP and water availability;dewatering of the Open Cut and controllingwater levels in the Underground workings;maintaining water supply to the Open Cut truckfill water tanks to provide water for dustsuppression;maintenance and testing of the Hunter RiverSalinity Trading Scheme (HRSTS) dischargesystem and upgrade;continued decanting of water from the HunterPit (emplacement area) and North East CutTailings to the Homestead Pit for reuse;maintenance of the fire water reticulationsystem to the Wambo Homestead complex;continued installation and refining of telemetryfor site water management and control;continued dewatering from the No. 2 and No.1boreholes;Dewatering of the Homestead Pit void;Completion of the Wollemi Brook pumpsupgrade;planning and execution of modifications towater management systems in the Open CutPage 28

2010-2011 AEMR2.8.1 Water Supply and UseContinuity of water supply to the CHPP, Open Cutand Underground is important for the processing ofcoal and the operation of the mine. During thisreporting period the site water balance for themining activities was recalculated. This waterbalance is presented in Table 2.5.WCPL manages its water supply through a numberof on site water storage dams. The mine routinelyobtains water from the Hunter River Licence(Number 20AL200631), Wollombi Brook Licence(Number 20SL033872), the Wollemi andHomestead goaf areas and from rainfall runoff.WCPL’s annual water catchment generally matchesoperational water requirements for CHPP and OpenCut usage. In 2009-2010, minimal water wasextracted from the Hunter River to supplementextraction via the Wollombi Brook pumps. Waterextracted from Wollombi Brook (and the HunterRiver) is used to supply the fire suppression systemand underground oprerations.2.8.2 Surface Water ManagementTo minimise the potential for water quality impactsfrom mining operations, a network of water storageshas been established to separate the clean water(runoff from undisturbed areas) and dirty water(runoff from disturbed areas). Rainfall runoff fromundisturbed areas is diverted away from miningareas. Runoff from areas disturbed by mining isdiverted into the onsite dams for use across the site.West Cut Dam and Area C Dam have now beendewatered and are now only sumps.The wash down and runoff water from the CHPPand adjacent stockpiles is accumulated insedimentation ponds which feed into the GordonBelow Franklin Dam network. The Gordon BelowFranklin Dam network is designed to slow the flowof the water and encourage the precipitation of finesediment to drop out. The sediment ponds arecleaned out on a regular basis using a variety ofmethods including dredging and truck andexcavator. Water from these dams is returned to theEagles Nest Dam. A new dredging programcommenced in late 2010 to remove excesssediment from the CHPP dam network.Water stored in South Wambo Dam, Chitter Damand Eagles Nest Dam complex is used in the coalwashing process and for dust suppression at theCHPP.Water is pumped to tank fill points in the Open Cutto allow water carts to fill and assist in dustsuppression. Water for this process is pumped fromthe storage dams and the Homestead Pit (North)decant dam.2.8.2.1 Water Balance & ModelingIn March 2010, WCPL completed a detailed reviewof the operations water balance. The water balanceis based on monitoring data from numerous waterflow meters on site and information provided byWCPL technical personnel.In addition, a comprehensive predictive site waterand salt model was finalised in February 2011, inaccordance with recent development consentrequirements. The completed water model includesa predictive accounting system for water and saltbudgets.2.8.2.2 NWC Discharge ReportIn April 2008, the North Wambo Creek (NWC)Diversion Plan was approved by DoPI, DTIRIS andNOW, subject to a number of approval conditions. Inaccordance with the approval conditions for theNWC Diversion Plan, WCPL must prepare andsubmit a flow assessment report after each flowevent down the diversion.In early June 2011, significant rainfall resulted increek flows down South Wambo Creek, StonyCreek and North Wambo Creek, including flowsdown the NWC Diversion. At the time of writing theAEMR, WCPL has engaged a consultant tocommence a flow assessment report of the NWCDiversion in accordance with the approvalconditions for the diversion. The results of the flowassessment report will be provided in the nextAEMR.NWC Diversion Flow Event June 2011Page 32

2010-2011 AEMRAs discussed in the last AEMR, WCPL submittedthe first North Wambo Creek Discharge Reportduring September 2009 in response to two flowevents in February and April 2009. The objectivesof the flow assessment report included:Providing a comparative assessment of theconditon of the NWC Diversion to several otherreference sites within South Wambo Creek andApple Tree Creek; andProvide recommendations for any remedialworks required.For further information regarding any remedialrecommendations within the NWC Diversion, pleaserefer to Section 5.1.4.2.8.3 Water DischargeWCPL’s water management system is currentlybalanced by the adjustment of flow from the variouswater sources and storages. However, whereexcess water is generated, WCPL has facilities todischarge water. This is done in accordance withEPL529, DA 305-7-2003, the Hunter River SalinityTrading Scheme (HRSTS), and Managed Envelopeof Residuals Flood (MERF) Scheme.EPL 529 approves discharge into Wollombi Brookwhen the flow is greater than 500 ML/day at theBulga gauging station, provided other conditions ofthe HRSTS and MERF are satisfied.On 30 June 2011, WCPL held a total of 61 saltcredits under the HRSTS scheme. During thereporting period there were 10 water discharge daysunder HRSTS or MERF, totalling 690.52MLdischarge.Table 2.5 – 2010-2011 Water BalanceWater Sources (ML)Hunter River 92Wollombi Brook 171United Borehole 0Rainfall/run off 3966Underground Seepage 588Open Cut Seepage 724Wollemi Sump 30Site Wells 0Total Water Input 5571Water Usage (ML)Dust Suppression615CHPP Consumption1020Underground362United0Domestic Usage3Total Water Usage 2000Water Loss (ML)Evaporation – Mine Water& Tailings Dams2489HRSTS/MERF Discharge 690Water Balance 392Page 33

2010-2011 AEMR2.9 Hazardous MaterialManagementWCPL has systems in place to ensure active andefficient management of hazardous material withinits operations. There are several locations on sitewhere hazardous material is stored. WCPL hasstorage areas at the Open Cut workshop,Underground and the CHPP. The Open Cut miningcontractor and other on-site contractors areresponsible for the maintenance and operation oftheir facilities.An audit of the storage and handling of hazardoussubstances and dangerous goods for the Open Cutwas carried out in November 2010. The audit wasintended to be a high level audit to determine andreport on the level of compliance with therequirements of relevant key legislation andAustralian Standards. Good practices wereobserved with several improvements regardingstorage and handling recommended.At WCPL, dangerous goods and explosives aremanaged separately under their respective piecesof legislation i.e. to comply with the updatedDangerous Goods Act 2005 and Explosive Act 2003respectively.2.9.1 Hydrocarbon ContainmentDiesel fuel for the Open Cut is stored above groundwithin specifically designed concrete bunding. Oiland grease storages on site are contained withinimpervious bunds and purpose built hydrocarbonstorage units. Diesel for the Underground is storedwithin a portable, self bunded (double walled)Transtank located at the portal area.All bulk fuel, oil and grease storage areas areregularly inspected as part of the internal monthlyenvironmental inspection schedule.As discussed there are a number of oily waterseparator systems located across the site. For moreinformation please refer to Section 2.6.3.2.9.2 Explosive ManagementIn addition to priming and initiating explosives, upto 120 tonnes of ammonium nitrate prill is stored intippers on site as well as 50 tonnes of AmmoniumNitrate Emulsion (ANE) for the Open Cutoperations. The ammonium nitrate is loadedinto mobile processing units (MPU) at a reloadfacility situated in the mine. The MPU is then drivenonto bench where all the ingredients are mixedentering into a blast holes. The ammonium nitratestorage area and the magazine areas wereupgraded last reporting period to conform with theExplosive Act 2003. The focus has been onincreased security.2.9.3 Material Safety Data SheetsAll materials stored on site have appropriateMaterial Safety Data Sheets (MSDS). No chemicalor hazardous material is permitted on site unless themine has a copy of the appropriate MSDS or, in thecase of a new product; it is accompanied by aMSDS. ChemAlert is used to maintain an electronicregister of chemicals on site. The Open Cutcontractor and other on site contractors areresponsible for the maintenance of a MSDS registerfor their areas.There is one decommissioned undergroundunleaded fuel storage tank adjacent to the lightvehicle car park that will be removed during the nextreporting period. During this reporting period WCPLengaged an independent environmental consultancyto validate compliance of the old underground tankagainst The Protection of the EnvironmentOperations (Underground Petroleum StorageSystems) Regulation 2008. After the validationprocess was completed, WCPL awarded a contractto remove the unleaded tank, with preliminary worksunderway by a licensed contractor at the end of thecurrent reporting period. A summary of theunderground tank removal will be provided in thenext AEMR.Page 34

2010-2011 AEMR3.0 EnvironmentalManagement andPerformance3.1 Meteorological Monitoring3.1.1 Environmental ManagementThe WCPL maintains a weather station inaccordance with the Australian Standard AS2923 –1987. The weather station is located approximately350m east of the WCPL administration building (seeFigure 3.1). The meteorological station wasapproved for relocation to its current position (seeFigure 3.1) by the OEH in December 2007. Asrequired under Schedule 4, Condition 10(a) ofDevelopment Consent DA 305-7-2003, themeteorological station records the followingparameters:temperature (at 2 m and 10 m);lapse rate;wind speed;wind direction;solar radiation;humidity; andsigma theta.Evaporation is calculated from this information, foruse in reports such as the site water balance.Meteorological information collected at the weatherstation is used on a daily basis for general miningactivities including the location of operating plantand equipment, and to minimise blasting impacts onthe neighbouring residences.3.1.2 Environmental PerformanceA malfunctioning solar radiation sensor resulted inreduced data capture rate between October 2010and February 2011. The sensor was replaced andrecalibrated in accordance with relevant AustralianStandards. Due to the malfunctioning solar radiationsensor and problematic commissioning issues withthe replacement sensor, the cumulative evaporationdata for October 2010 to February 2011 was notavailable. The evaporation data for these monthswas substituted with monthly averages from 2005 to2010. A summary of weather data recorded duringthe reporting period is provided below and inAppendix 2A.3.1.3 Rainfall and EvaporationThe monthly and cumulative rainfall and evaporationdata for the 2010-2011 reporting period is providedin Figure 3.2 below. The long term annual averagerainfall is from the Bureau of Meteorology Jerry’sPlains Post Office weather station, which hasrecorded weather data since 1884, is provided inAppendix 2A.A total of 741.0mm of rainfall was recorded atWCPL during the reporting period, of which 121.2mm was recorded in November 2010. The long-termaverage (1884 – 2010) recorded at the Jerry’sPlains Post Office weather station is 641.4 mm.Rainfall recorded during the previous reportingperiod (2009-2010) was 564.3 mm.3.1.4 TemperatureThe maximum and minimum temperatures recordedduring the 2010-2011 reporting period are shown inFigure 3.3 below. The maximum temperature of42.5 0 C was recorded in January 2011, the lowesttemperature of -5.7 0 C was recorded in July 2010.The seasonal average temperatures recordedduring the reporting period were as follows: 11.1 0 Cin winter; 17.8 0 C in spring; 24.1 0 C in summer; and17.1 0 C in autumn. These results are typical oftemperature variations in this region.3.1.5 Wind Speed and DirectionThe dominant winds recorded during the 2010-2011reporting period were from the north west and southeast directions with the strongest winds blowingfrom the NW. The maximum average wind speed of4.8 m/s was recorded in September and October2010. The mean monthly wind speed variedbetween 1.5 m/s to 2.2 m/s, with the yearly averagebeing 1.9 m/s. The annual and seasonal wind rosesfor the reporting period are shown in Figure 3.4 toFigure 3.8.Page 35

2010-2011 AEMR3.2 Air Quality3.2.1 Environmental ManagementDust generation is primarily managed by roadmaintenance and consolidation, and utilising watercarts to apply recycled mine water onto internalroads and other disturbed areas. Other dust controlmeasures during the reporting period included:Induction training to all employees highlightingtheir responsibility to limit the level of dustproduced; Rehabilitation of disturbed land on aprogressive basis to reduce total disturbedarea;Keeping disturbance areas to a minimum byminimising the disturbance in advance ofmining operations until mining is due tocommence in the area and clearly definingroads; Modifying mining operations duringunfavourable weather conditions to reduce dustgeneration;Dust suppression equipment is fitted andoperated on drills;Regular servicing of water carts for effectiveroad watering and continual operation;Revegetating topsoil stockpiles which are notplanned to be used for over three months;Designing blast holes with stemming to provideoptimum confinement of the blast charge;Constraints on blasting operations to reduceimpact of immediate neighbours (e.g. reschedulingblasts when wind blowing towardsimmediate neighbours);Cleaning up coal spillage around the CHPP toprevent dust; andFitting dust suppression systems at transferpoints where necessary.WCPL operate under an approved Air QualityMonitoring Program (AQMP), a requirement ofConsent Conditon 5, Schedule 4 of DA305-7-2003.The AQMP was revised to address operationalchanges and re-submitted to the DoPI in June 2008.In accordance with Consent Conditon 4, Schedule4, DA305-7-2003 and the AQMP, WCPL maintainedfour air quality monitoring stations AQ01, AQ02,AQ03 and AQ04 (see Figure 3.1). Each air qualitymonitoring station consists of a Tapered ElementOscillating Microbalance (TEOM) unit monitoringPM 10 , a High Volume Air Sampler (HVAS) unitmonitoring Total Suspended Particulates (TSP) anda dust depositional gauge.In accordance with the AQMP, WCPL hasmaintained and operated the following air qualitymonitoring equipment, throughout the reportingperiod:Four HVAS units measuring TSP; Four real time TEOM units measuringparticulate matter of 10 microns in diameter(PM 10 ) on a continuous basis; andSixteen depositional dust gauges.3.2.2 Environmental PerformanceAll air quality monitoring conducted at WCPL duringthe 2010-2011 reporting period was measured andmonitored against the impact assessment criteriastipulated in Consent Condition 2, Schedule 4 of DA305-7-2003 and in accordance with EPL 529, whichapply at any privately owned residences as follows:Use of additional contractor water trucks towater frequently used roads around the CHPPas required;Operation of two water truck fill points duringthe reporting period to reduce the time betweenroad watering;Operation of water sprays during raw coalunloading at the ROM dump hopper;Regular use of a road sweeper on the mainaccess road into WCPL;Implementing speed limits on roadways; TSP Annual Average Impact Assessmentcriteria less than 90 µg/m3;PM 10 annual average assessment criteria lessthan 30 µg/m3;PM 10 24 hour assessment criteria of less than50 µg/m3;Deposited dust annual average assessmentcriteria less than 4 g/m2/month; andDeposited dust maximum increase in depositeddust level of less than 2 g/m2/month.Page 40

2010-2011 AEMRIn accordance with Condition 5(b), Schedule 6 ofDA 305-7-2003, a comparison of the air qualityresults for the reporting period at any privatelyowned land were compared against the modelledpredictions in the 2003 Environmental ImpactStatement (2003 EIS) (see Appendix 2B).The 2010/2011 results for TSP and depositionaldust were consistent with modelled predictions atAQ04; however the TSP results were elevated atAQ03. AQ03 is located adjacent to an active horseholding yard, which historically has influenced airquality monitoring results at this location. In additionseveral regional dust events influenced the annualaverage (see Section 3.2.2.1).Depositional dust results at D12 and D11 were alsoelevated compared to the modelled results in the2003 EIS. D12 is located approximately 700m eastfrom the mining operations (see Figure 3.1). Theproperty which D12 is located on is also within thezone of compulsory acquisition as identified in Table1 of DA305-7-2003. During the reporting period, theprivate property on which D12 is located waspurchased by an adjacent coal mining operation.D11 is located approximately 4km south from themining operations along an unsealed section ofWambo Road. The gravel road has historicallyinfluenced air quality monitoring results at thislocation.The annual average TSP and dust depositionalresults for the reporting period did not exceed theimpact assessment criteria at any privately ownedresidence.The 2010-2011 results for PM 10 were consistentwith EIS modelled predictions at AQ04 and AQ03.3.2.2.1 High Volume Air SamplingMonitoring of TSP occurred at four locations duringthe reporting period;1. HV01 – Coralie2. HV02 – Wambo Road3. HV03 – Thelander4. HV04 - MullerAll four HVAS continued to operate on a six daycycle (in line with the OEH cycle) during thereporting period. The locations of the HVAS areillustrated in Figure 3.1. Both HV01 and HV02 arelocated on WCPL owned land. HV03 and HV04 arelocated on privately owned land. All of the HVASunits had a capture rate of 100% during the 2010-2011 reporting period. The TSP results recorded ateach of the HVAS sites are illustrated in Figures3.9a-d below and provided in Appendix 2B.The annual average TSP concentration at all fourmonitoring locations did not exceed the long termimpact annual average criteria of 90g/m 3 on anyprivately owned land. The annual average TSPresults at HV03 for 2010-2011 recorded an increaseof 9g/m 3 when compared to the annual averagereported in the 2009-2010 AEMR. The annualaverage TSP results at HV04 for 2010-2011recorded a decrease of 7g/m 3 when compared tothe annual average reported in the 2009-2010AEMR.Two elevated daily TSP results, of 238g/m 3 and285g/m 3 , were recorded at HV03 on the 15/12/10and 26/01/2011, respectively. A review ofmeteorological conditions indicated that:the wind direction on the 15/12/10 commencedfrom the east and later swung around to thewest during the morning and remained from thewest, with an average wind speed of 1.7m/sand gusts up to 2.9m/s; andthe wind direction on the 26/01/11 waspredominately from the west and the southwest. The wind speed averaged 1.1m/s, withwind gust up to 3.5m/s; andHV03 is located north west of the mine andtherefore under these metrological conditions isconsidered outside the influence of WCPL miningactivities. In addition, all four HVAS units recordedhigh TSP results on the 26/01/2011 suggesting aregional dust event was occurring.The highest annual average TSP of 60g/m 3 wasrecorded at HV01, which was below the annualaverage criteria of 90g/m 3 . HV01 is locatedadjacent to the mine entry road on WCPL ownedland. The higher annual TSP result can be attributedto an increase of mining related traffic utilising thisarea as a temporary hard stand area toaccommodate a number of contractors.There were two very high TSP results of 252g/m 3253g/m 3 recorded at HV01 and HV02 on 16/10/10and 28/10/10, respectively. A review ofmeteorological conditions for both days indicatedthat:the wind direction on the 16/10/11 waspredominately from the west, averaging 3.4m/swith wind gusts up to 4.8m/s. HV01 isapproximately 500m east of WCPL miningoperations, indicating potential for mine dustcontribution.Page 41

2010-2011 AEMRthe wind direction on the 28/10/11 waspredominately from the south and the southeast, averaging 1.36m/s, with a wind gust up to4.2m/s. HV02 is located south of the mine andtherefore under these metrological conditions isconsidered outside the influence of WCPLmining activities.3.2.2.2 PM 10Four real-time TEOM PM 10 units were in operationduring the reporting period as part of the air qualitymonitoring program:1. AQ01 – Coralie2. AQ02 – Wambo Road3. AQ03 – Thelander4. AQ04 - MullerEach TEOM PM 10 unit records the PM 10 particulatesevery 15 minutes and calculates the 24 houraverage, which is compared to the relevant criteriamentioned above. Units AQ01, AQ02, AQ03 andAQ04 had a capture rate of 87%, 96%, 99% and96% per unit respectively. Intermittent powerfailures and instrument malfunctions were identifiedas the primary cause of equipment failure. A faultyair conditioning unit for AQ01 also contributed toshort term periodic unit failure. All TEOM PM 10 unitshave power surge protection devices fitted to protectagainst power surges. The locations of these TEOMPM 10 units are shown in Figure 3.1.54.9g/m 3 on the 05/01/11 and 04/02/11respectively. This is in contrast to a total of sevenexceedances of the daily 50g/m 3 limit on at AQ03during the previous reporting period. A review ofmeteorological conditions for both days indicatedthat:the wind direction on the 05/01/11 waspredominately from the south east with anaverage wind speed of 1.52m/s. HV03 is northwest of WCPL mining operations, thereforewithin the influence of WCPL mining activitiesunder these meteorological conditions.However, a review of the daily results fromAQ04 recorded a much lower result of27.3g/m 3. AQ04 is located approximately1.5km north east of AQ03 (see Figure 3.1).the wind direction on the 04/02/11 waspredominately from the south west, with anaverage wind speed of 1.8m/s. HV03 is northwest of WCPL mining operations, thereforeoutside the influence of WCPL mining activitiesunder these meteorological conditions. Inaddition, a review of the daily results fromAQ04 recorded a much lower result of28.4g/m 3Results recorded from the PM 10 units are illustratedin Figure 3.10a-d below and tabled in Appendix2B.The PM 10 annual average concentration at all fourmonitoring locations did not exceed the annualaverage criteria of 30 g/m 3 limit on privately ownedland during the reporting period.There were only two exceedances of the daily50g/m 3 limit on privately owned land at AQ03during the reporting period of 57.3g/m 3 andPage 42

2010-2011 AEMR3.2.2.3 Dust DepositionWCPL maintains a network of 16 dust depositiongauges, the location of each dust deposition gaugeis shown in Figure 3.1.All depositional dust gauges were sampled andanalysed for insoluble solids and ash residue, inaccordance with AS3580.10.1:2003 Methods forSampling and Analysis of Ambient Air and NationalAssociation of Testing Authorities (NATA)requirements. A summary of the annual averagesfor the 16 dust gauges is provided in Figure 3.11below and a full summary of the monthly resultsprovided in Appendix 2B. There was a capture andanalysis rate of 100% for all dust gauges. Nearly alldust gauges contained various sources of foreignmaterial including bird droppings, insects and otherorganic matter when analysed.Contamination was assessed based on fieldobservations, laboratory observations and analysis(microscopic and qualitative), historical data andwind patterns. All monthly dust results deemed to becontaminated were excluded from the annualaverage.There were no depositional dust gauges thatexceeded the annual average criteria of 4g/m 2 /month on privately owned land (see Figure3.11). The annual average rainfall for the 2010/2011reporting period was approximately 176.3 mmgreater than the previous year. A higher thanaverage rainfall for 2010/2011 is anothercontributing factor with respect to lower annual dustaverages, compared to 2009/2010 reporting period.Dust gauges D07 and D14 exceeded the averagecriteria of 4 g/m 2 /month, however these dust gaugesare situated on WCPL owned land and therefore theaverage criteria of 4 g/m 2 /month does not apply.D07 is located near an internal unsealed road, usedregularly during the reporting period. D14 is locateddirectly west of the advancing open cut and withinthe footprint of the disturbance area.All other dust gauges located on residentialproperties (D11, D12, D17, D21, D22, D24 andD25) were below the annual average criteria of4g/m 2 /month.Assessment criterion of a maximum increase of2g/m 2 /month annual average for deposited dust wascompared with annual average deposited dustresults from the previous reporting period (seeFigure 3.11a). There were no exceedances of the2g/m 2 /month criterion when compared with dustresults from the 2009/2010 reporting period.The intention of this criterion is to distinguish dustcontribution by WCPL from other sources.

2010-2011 AEMR3.3 Erosion & SedimentControl3.3.1 Environmental ManagementErosion and sedimentation is managed inaccordance with WCPL Erosion and SedimentControl Plan (ESCP), a requirement of ConsentConditon 32, Schedule 4 of DA305-7-2003. TheESCP is a component of WCPL’s Site WaterManagement Plan as required under Condition 30,Schedule 4 of DA305-7-2003. The main principlesof the ESCP include: Separation of runoff from disturbed andundisturbed areas where practicable; Construction of sediment structures orutilisation of existing mine water storages tocapture runoff up to a specified design criterion;Construction of surface drains to facilitate theefficient transport of surface runoff. Drains aredesigned using trapezoidal or parabolic crosssections;andProgressive rehabilitation stabilisation of mineinfrastructure areas.These principles take into account the generalrecommendations for site drainage works presentedin “Managing Urban Stormwater – Soils andConstruction Volume 1” (Landcom 2004).A number of strategies are used on site for erosionand sediment control including:The establishment of diversion banks on theupstream side of the site to divert clean wateraround the site and into natural drainage lines;The establishment of sediment fencing asrequired on the down-slope side of soilstockpiles;The use of a street sweeper to remove dirt andmud from mine access roads;Monthly monitoring of all sediment controlstructures and maintenance when required;Limiting clearance and disturbance of thenatural environment; andProgressive rehabilitation across site.3.3.2 Environmental PerformanceMonthly inspections of sediment control structuresas well as inspections following rainfall events of 20mm or more in a 24 hour period are conductedacross the mine by WCPL personnel andcontractors. During these inspections, sedimentcontrol structures are inspected for capacity,structural integrity and effectiveness.The routine removal of sediment from a number ofthe sediment control structures, including HalesCrossing Sediment Dam was undertaken during thereporting period. As discussed in the last AEMR, aplan of works to remove coal sediment from a seriesof purpose built sediment dams around the CHPPand product stockpile areas was scheduled for2011. Dredging to remove coal fines and increasethe dam capacity within the Gordon Below FranklinDam commenced in June 2011. The recovered coalfines were reprocessed through the CHPP. The establishment of catch drains inaccordance with relevant criteria (outlined in theESCP) to direct sediment-laden water intosediment control structures; The strategic placement and design ofsediment control structures on site to treatsediment laden water before it leaves site;The placement of hay bales along catch drainsto control the velocity of flow and preventscouring;The establishment of sediment ponds orutilisation of existing mine water structures totreat sediment laden water;Dredging GBF Dam in June 2011During the reporting period WCPL completed aremedial rehabilitation program within the NWCDiversion. Please refer to Section 5.1.4 for furtherdetails about the NWC Diversion rehabilitationworks.Page 47

2010-2011 AEMR3.4 Surface Water3.4.1 Environmental ManagementSurface water monitoring is undertaken inaccordance with WCPL’s Surface Water MonitoringProgram (SWMP), a requirement of ConsentCondition 33, Schedule 4 of DA305/7/2003. TheSWMP is a component of WCPL’s Site WaterManagement Plan as required under Condition 30,Schedule 4 of DA305-7-2003. In addition, theSWMP has also been prepared to fulfil WCPL’s EPL529 license conditions.The SWMP has previously been prepared to thesatisfaction of DoPI and SSC and in consultationwith DTIRIS and NOW. The SWMP was approvedby the DoPI in October 2005. WCPL revised theSWMP in October 2008 and November 2009 andre-submitted the surface water monitoring programto the relevant government departments toaccommodate operational changes anddevelopment consent modification requirements.At the end of the reporting period, WCPL were stillawaiting responses from both the DoPI and NOWregarding the revised SWMP. WCPL receivedofficial notification from the DTIRIS during April2010 accepting the changes to the SWMP.In accordance with SWMP, WCPL maintainedsurface water monitoring sites, located within:Wollombi Brook, Doctors Creek, LongfordCreek, North Wambo Creek, South WamboCreek and Stony Creek; andmine water storage dams including Eagles NestDam, Chitter Dam and South Dam.WCPL participates in the HRSTS which allowswater to be discharged into the Wollombi Brookfrom the licensed discharge point SW15 (EaglesNest Dam) as listed in EPL 529. For further detailsof water discharges refer to Section 2.8.3.3.4.2 Environmental Performance3.4.2.1 Water QualitySurface water quality criteria for pH, ElectricalConductivity (EC) and Total Suspended Solids(TSS) for the monitoring locations at WCPL areprovided in Table 3.1. The surface water qualitycriteria for pH and TSS were adopted from thedischarge criteria (i.e. Schedule 4, ConsentCondition 24 of DA 305-7-2003, and Condition L3.3of EPL 529) and the HRSTS.The results in Section 3.4.2 of the 2010-2011AEMR for surface water are for those surface watermonitoring sites required for monitoring inaccordance with approved in the 2005 SWMP.Table 3.1 – Surface Water Quality CriteriaStream SystempH CriteriaEC Criteria(µS/cm)TSS Criteria(mg/L)WCPL Mine SiteWollombi Brook 6.5 - 9.0 3,106 120North Wambo Creek 6.5 - 9.0 2,093 120Eagles Nest Dam 6.5 - 9.5 N/A * 120South Wambo Creek 6.5 - 9.0 492 120Stony Creek 6.5 - 9.0 492 120Wambo Rail DevelopmentWollombi BrookLongford CreekDoctors CreekLess than 20% morethan upstreamconcentrationLess than 20% morethan upstreamconcentrationLess than 20% morethan upstreamconcentrationNote: * Under Schedule 4, Condition 24 of DA 305-7-2003 and condition L3.3 of EPL 529 theEagles Nest Dam discharge point is not required to be monitored for EC.^ ANZECC Guidelines for Fresh and Marine Water Quality (2000).Page 48

2010-2011 AEMRTrigger levels for EC however have been derivedfrom historical monitoring data (using a minimum of24 data points), where available, in accordance withthe Australia and New Zealand Environment andConservation Council Guidelines for Fresh andMarine Water Quality (ANZECC Guidelines)(ANZECC, 2000).Additional surface water monitoring in naturalwaterways (except Hunter River) and mine waterdams including Eagles Nest Dam is also undertakenafter rainfall events of more than 20 mm rain in 24hours (12 am to 12 am). The monthly surface waterquality results for the reporting period are discussedbelow.For the complete monthly surface water quality andrainfall event sampling results during the reportingperiod, please see Appendix 2C.All surface water samples are monitored for pH andElectrical Conductivity (EC) on a monthly basis.Surface water samples from natural waterways(except Hunter River) and mine water damsincluding Eagles Nest Dam, South Dam and ChitterDam are also analysed for total dissolved solids(TDS) and Total Suspended Solid (TSS). Inaddition, monitoring of oil and grease concentrationsis also undertaken. Additional monitoring of minewater dam sites are not required under the SWMP,however mine water quality is analysed for saltbudgeting and for operational purposes.EC and pH are measured in the field while samplesare collected and analysed in the laboratory forTDS, TSS, oil and grease. Surface water samplesare collected in accordance with AS/NZS5667.4:1998 – Guidance on sampling from lakes,natural and man-made and AS/NZS 5667.6:1998 –Guidance on sampling of rivers and streams.A number of surface water monitoring sites withinNorth Wambo Creek, South Wambo Creek andStony Creek were dry during the monthly samplingregime and therefore no water samples could beobtained.Surface water monitoring undertaken in accordancewith SWMP indicated that WCPL’s miningoperations had minimal influence on the waterquality of the surrounding natural water coursesduring the reporting period.3.4.2.2 pH AnalysisThe recorded pH values from the surface watermonitoring program during the reporting period arepresented graphically and tabulated in Appendix2C.The pH levels for the Eagles Nest Dam during the2010-2011 reporting period were within the pHcriteria and ranged from 8.50 to 9.20. In general,mine water quality within Eagles Nest Dam istypically more alkaline than pH values of thesurrounding natural creeks and streams.The recorded pH for the creeks and streamssurrounding the operation varied depending onrainfall and volumetric flow.Wollombi Brook recorded average pH values of7.32, 7.51, 7.53 and 7.45 at surface watermonitoring sites SW01, SW02, SW03 and SW40respectively. All monthly recorded pH values werewithin the SWMP surface water quality criteria.South Wambo Creek and Stony Creek recordedaverage pH values of 7.65, 7.25 and 7.41 at surfacewater monitoring sites SW06, SW07 and SW08respectively. All monthly recorded pH values werewithin the SWMP surface water quality criteria.North Wambo Creek recorded pH average valuesranging from 7.52 and 7.69 at surface watermonitoring sites SW05 and SW27 respectively.There was only one result obtainable at SW32 dueto dry conditions within the creek at each time ofsampling during the reporting period. The onesample returned a pH value 8.20. All monthlyrecorded pH values were within the SWMP surfacewater quality criteria.The recorded pH values monitored at SW39 and theWRD surface water sites (i.e. Doctors and LongfordCreeks) were within the surface water qualitycriteria.3.4.2.3 Total Suspended SolidsThe recorded TSS values from the surface watermonitoring program during the 2010-2011 reportingperiod are graphically presented and tabulated inAppendix 2C.Variations in TSS for the Eagles Nest Dam duringthe 2010-2011 reporting period were within surfacewater quality criteria limits and ranged from 15 mg/Lto 46 mg/L.Variations in TSS observed throughout the yearwithin the surrounding natural creeks and streamswere attributable to rainfall events. The monthlyrecorded TSS concentrations within the naturalwaterways surrounding the operations generallyremained below the criteria of 120 mg/L, with thePage 49

2010-2011 AEMRexception of results recorded in November 2010and March 2011 (121.2mm and 94.4mmrespectively) due to several significant rainfallevents.Wollombi Brook recorded average TSSconcentrations of 10mg/L, 10mg/L, 15mg/L and18mg/L at surface water monitoring sites SW01,SW03, SW02 and SW40 respectively. All monthlyrecorded TSS concentrations were within theSWMP surface water quality criteria. All annualaverage TSS concentrations for Wollombi Brookduring the 2010-2011 AEMR reporting period wereconsistent with the average TSS concentrationsrecorded in the previous 2009-2010 AEMR.South Wambo Creek and Stony Creek recordedaverage TSS concentrations of 25 mg/L, 27 mg/Land

2010-2011 AEMRWollombi Brook recorded average EC values of731S/cm, 1076S/cm, 1243S/cm and 566S/cmat surface water monitoring sites SW01, SW02,SW03 and SW40 respectively. All annual averageEC concentrations for Wollombi Brook during the2010-2011 AEMR reporting period were lowercompared to the average EC concentrationsrecorded in the previous 2009-2010 AEMR. Allmonthly recorded EC values during 2010-2011 werewithin the SWMP surface water quality criteria, incontrast with the results from SW03 during the2009-2010 AEMR. During the last reporting periodthere were five occasions at SW05 where the ECcriteria was not achieved due to low flows in thebrook. However, the Wollombi Brook sustainedgood flows during this reporting period, resulting inlower EC concentrations.South Wambo Creek and Stony Creek recordedaverage EC values of 500S/cm, 554S/cm and325mg/L at surface water monitoring sites SW06,SW07 and SW08 respectively. All annual averageEC concentrations for South Wambo Creek andStony Creek during the 2010-2011 AEMR reportingperiod were lower when compared to the averageEC concentrations recorded in the previous 2009-2010 AEMR.All monthly recorded EC values during 2010-2011were within the SWMP surface water quality criteriafor SW08. Although the monthly EC criterion wasnot achieved on several occasions at SW06 andSW07. Both sites are upstream of WCPL miningoperation and therefore considered outside theinfluence of mining.Regular water samples were taken from SW05 andSW27 within North Wambo Creek during thereporting period and only one sample was taken atSW32 due to the creek being mostly dry at thislocation. EC results at SW05 did not meet the ECcriteria of 2140S/cm on several occasions. InAugust 2010 and September 2010 EC results of2,250S/cm and 2310S/cm were recordedrespectively. However the average ECconcentration at SW05 of 1390S/cm wasconsiderably lower than the previous year. Asexpected the EC criteria was achieved at SW05after good rainfall in November 2010 and June2011, where the measured EC was 281S/cm and405S/cm respectively.EC concentrations at SW39 exceeded the surfacewater quality criteria on two occasions. SW39 is tothe north west of the operations where grazingactivities occur on WCPL land under a private leasearrangement and therefore considered outside theinfluences from mining.Results from the WRD water monitoring programshow that EC in the Wollombi Brook achieved theEC criteria.As discussed above, surface water sites at LongfordCreek (SW43 and SW44) are adjacent to theGolden Highway and considered outside theinfluence of any WCPL activities. Additionallysurface water sites at Doctors Creek (SW46 andSW45) are immediately downstream from nonWCPL agricultural and mining activities, includingcattle grazing and coal stockpiling.Doctors Creek also provides for the passage ofmine water discharged from a neighbouring mine tothe Hunter River. During the reporting period therewere a number of visual confirmations that severaldischarges to Doctors Creek were beingundertaken. The high EC periodically recorded atDoctors Creek is consistent with these events.3.4.2.5 Oil and GreaseOil and grease results recorded during the reportingperiod concluded that oil and grease concentrationsin the surrounding waters were generally incompliance with the criteria set out in the WRDSWMP. Oil and grease results recorded during the2010-2011 reporting period are tabulated inAppendix 2C.3.4.2.6 Flow MonitoringIn consultation with NOW, WCPL completed aprogram to re-install all nine surface water flow sitesdestroyed during the June 2007 floods. Thereplacement program involved the installation ofhydrographic stations in North Wambo Creek, SouthWambo Creek and Stony Creek, the locations ofeach flow monitoring site are illustrated in Figure3.1NWC Flow monitor site FM1 – April 2009Page 51

2010-2011 AEMRThe results of the flow monitoring program withinNorth Wambo Creek, South Wambo Creek andStony Creek are presented in Appendix 2C.Volumetric flow monitoring in Wollombi Brook isundertaken at Bulga and Warkworth, the results areobtained from the NOW website.3.5 Groundwater Management3.5.1 Environmental ManagementWCPL operates in accordance with theGroundwater Monitoring Program (GWMP). TheGWMP was approved by the DoPI in October 2005.WCPL revised the GWMP in July 2008 and January2010, re-submitting the GWMP to the relevantgovernment departments to accommodateoperational changes, report recommendations anddevelopment consent modification requirements.At the time of writing the 2010-2011 AEMR, WCPLwere still awaiting responses from both the DoPIand NOW regarding the latest revision of theGWMP. WCPL received official notification from theDTIRIS during April 2010 accepting the changes tothe revised GWMP.The results in Section 3.5.2 of the 2010-2011AEMR for groundwater are for those groundwatermonitoring sites approved in the 2005 GWMP.Appendix 2D contains all and groundwatermonitoring results from the expanded network ofgroundwater monitoring sites undertaken during thereporting period.The overall objectives of the GWMP are to establishbaseline groundwater quality and water level dataand to implement a programme of data collectionthat can be utilised to assess potential impacts ofmining activities on the groundwater resources ofthe area.From a hydrogeological perspective, the Wamboarea is relatively complex due to the occurrence ofalluvium it’s proximity to Wollemi National Park anda number of historical and proposed miningdevelopments. Due consideration must also be paidto constraints imposed by the existing and proposedmining operations.Groundwater data is collected on-site on abimonthly basis and records from 1994 are availablefor some sites. During the 2008-2009 reportingperiod WCPL initiated an independent review of thecurrent groundwater monitoring network,undertaken by a specialist groundwater hydrologist.The outcomes of that review concluded anexpansion of the groundwater monitoring networkwas required for current and future miningoperations. Based on the recommendations fromthe review, a total of 11 new groundwatermonitoring bores were installed in 2009-2010 withan additional vibrating wire piezometer installedduring 2010-2011. The groundwater monitoringnetwork now consists of 31 monitoring sites. Thesesites consist of purpose constructed monitoringbores (also referred to as piezometers); watersupply bores, and bores owned by neighbouringlandholders. Actual bores may be standpipemonitoring bores, stock wells or multiple vibratingwire piezometers. Appendix 2D presents theresults from the groundwater monitoring network.The location of groundwater sites monitored duringthe reporting period are illustrated in Figure 3.12.All groundwater samples were collected inaccordance with AS/NZS 5667.11:1998 – Guidanceon sampling of ground waters. All samples collectedwere analysed in the field for pH, electricalconductivity (EC), temperature and depth to water.3.5.2 Environmental PerformanceThe purpose of groundwater impact assessmentcriteria is to provide “Trigger Levels” for each of thekey groundwater parameters, that is, depth to water,pH and EC. The “Trigger Levels” for each existingmonitoring site used in the GWMP has beenassessed through review of the historical water leveland water quality data. For the depth to water leveland EC, the upper and lower trigger levels havebeen assigned as two standard deviations greaterand less than the maximum and minimum observedvalues. In terms of pH, the lower and upper triggerlevels have been specified as 6.0 and 9.5respectively which encompass the normal range forgroundwater. To date, few pH values at eitherWCPL or United Collieries have been measuredoutside this range.The groundwater quality criteria from the updatedGWMP which were applicable to groundwatermonitoring sites from December 2005 aresummarised in Table 3.2.The depth to water monitoring results during thereporting period are illustrated in Figures 3.13a-b to3.17 and provided in Appendix 2D. All water levelsare measured from the top of the borehole casing.3.5.2.1 Depth to WaterIn general water levels remained static for most ofthe reporting period, with most groundwatermonitoring sites displaying a recovery of waterlevels through this period. Good rainfall events inPage 52

2010-2011 AEMRNovember and December 2010 of 121.2mm and54.5mm respectively and again during May andJune 2011 of 77.5mm and 98.6mm respectivelysupported this recovering trend.Groundwater WellsGW02 and GW11 located on the Brosi propertywere monitored throughout 2010-2011. The waterlevels remained mostly static for the period.Groundwater monitoring in 2010-2011 identifiedrecovery of water levels in GW11 and GW02towards the end of the reporting period.piezometers with recovering water levels towardsthe end of the reporting period. During this reportingperiod P301 water levels were maintained within itsrespective depth to water level criteria.Due to insufficient water being available to samplethroughout the reporting period at P315, only onewater level was recorded in June 2011. The oneresult recorded was within the respective criteria forP315.During this reporting period both water levels inGW02 and GW11 remained within their respectivewater level criterion. In contrast, both water levelsin GW02 and GW11 during 2009-2010 droppedbelow their respective standing water levels on oneoccasion before recovering.GW08 and GW09 are located on WCPL propertyand were monitored throughout the 2010-2011period. The water levels remained mostly static forthe period. Groundwater monitoring in 2010-2011identified only minor decreases and fluctuations ofwater levels at the end of the reporting period. Asrecorded in the 2009-2010 reporting period, thewater level at GW09 again remained outside thewater level criterion during the 2010-2011 reportingperiod.100 and 200 Series PiezometersThe 100 and 200 series piezometers locatedadjacent to the Wollombi Brook were monitoredthroughout 2010-2011. All standing water levelswere within their respective criteria’s for all the 100series piezometers, with most of the 100piezometers displaying recovering water levelstowards the end of the reporting period. Thisrecovery trend coincided with good rainfall, a total of98.6mm during June 2011.The 200 series piezometers also displayed thesame characteristics as the 100 series piezometersin terms of recovering water levels towards duringJune 2011. There was no access to P202 during theJune 2011 round of monitoring, due to the heavyrainfall providing for unsafe driving conditions.300 Series PiezometersThe 300 series piezometers are located adjacent toStony Creek. P301 piezometer also displayed thesame characteristics as the 100 and 200 seriesPage 53

2010-2011 AEMRUnited Collieries PiezometersThe United Collieries network of piezometersdisplayed largely static water levels for most of thereporting period. With the exception of P1, P11,P12, P13 and P15, all otherpiezometersperiodically exceeded their respective maximumwater level depths. The overall trend at the end ofthe reporting period displayed recovering waterlevels approaching their respective criteria. Goodrainfall in June 2011 was likely to have influencedthis recovering trend.3.5.2.2 pHThe results for pH analysis of the groundwatermonitoring network are provided graphically andtabulated in Appendix 2D.The pH values for groundwater in wells GW02,GW08, GW09 and GW11 remained within theGWMP trigger levels during the reporting periodwith pH values averaging from 6.6 to 8.8. Thegroundwater wells GW02 and GW11 located on theBrosi’s property are subject to the ANZECC criteriafor “Raw Waters for drinking purposes subject tocoarse screening”. GW02 and GW11 were withinthe ANZECC pH range of 6.5-8.5 for the wholemonitoring period.All pH values recorded during the 2010-2011reporting period for the 100, 200 and 300 seriesremained within the pH trigger limits. These valuesin contrast to the last reporting period when the pHat P202 and P301 periodically fell below theirrespective pH trigger limits.All pH values recorded during the 2010-2011reporting period for the United Collieriespiezometers remained within their respective pHtrigger limits as listed in Table 3.2.3.5.2.3 Electrical ConductivityThe results for EC analysis of the groundwatermonitoring network are provided graphically andtabulated in Appendix 2D.Groundwater wells GW02, GW08 and GW11remained within the GWMP trigger levels for ECduring the reporting period, with the exception ofGW09. The recorded EC at GW09 fell below theminimum EC criterion of 1500S/cm with a result of459S/cm for December 2010, with an annualaverage 1085S/cm.The measured EC in the 100 and 200 piezometerseries stayed relatively static during the reportingperiod. The measured EC for P106, P109, P110,P111, P114, P202 and P206 remained within theirrespective criteria for EC. The EC at P116periodically dropped below the EC criteria of1500S/cm during the reporting period with a resultof 1315S/cm for August 2010 and an annualaverage of 1790S/cm. The EC results recorded inthe 2010-2011 reporting period for both the 100 and200 piezometer series were consistent with ECresults recorded in the 2009-2010 period.The measured EC in the 300 series piezometersduring the reporting period remained relativelystatic. The measured EC values at P301 fell belowtheir minimum EC trigger level of 8500S/cm withan annual average 3117S/cm and a minimum ECvalve of 2420S/cm for June 2011. The EC resultsrecorded in the 2010-2011 reporting period for the300 piezometer series were consistent with ECresults recorded in the 2009-2010 period.The United Collieries monitored piezometersgenerally remained within their respective ECcriteria levels during the reporting period. A numberof United’s piezometers returned EC values wellbelow their respective minimum EC trigger levels.The EC results recorded in the 2010-2011 reportingperiod for the United Collieries piezometers wereconsistent with EC results recorded in the 2009-2010 period.3.6 Contaminated Land3.6.1 Environmental PerformanceThe highest potential for land contamination atWCPL is from hydrocarbons. The main areas withthe potential for land contamination are thehydrocarbon storage and refuelling areas. Allhydrocarbon storage areas are routinely inspectedas part of WCPL Environmental ManagementSystem (EMS). All hydrocarbon storage areas atWCPL, with the exception of the decommissionedunderground unleaded fuel tank at theadministration area, are managed within bundedareas. These concrete bunded areas are regularlymonitored and maintained, reducing the risk of anyhydrocarbon spillage. The decommissionedunderground unleaded fuel tank has previouslybeen pressure tested to ensure its integrity issatisfactory.During the 2009/2010 reporting period, WCPLdeveloped a detailed scope of works to remove theold underground unleaded fuel tank and itsPage 57

2010-2011 AEMRassociated fuel bowser, in response an audit reportrecommendation. As discussed in Section 2.9.1,WCPL engaged an independent environmentalconsultancy to validate compliance of the facilityagainst The Protection of the EnvironmentOperations (Underground Petroleum StorageSystems) Regulation 2008. After the validationprocess was completed, WCPL awarded a contractto remove the underground tank, with preliminaryworks underway at the end of the reporting period.A summary of the underground tank removal will beprovided in the 2011-2012 AEMR.As discussed in the last AEMR, WCPL and DownerEDI were finalising procedures and location of thenew bioremediation site within the Open Cut. Thisfacility in now operational to accept and treathydrocarbon contaminated material. Further detailsregarding the bioremediation site are discussed inSection 3.17.Both plans include a Vegetation Clearance Protocoland Threatened Species Management Protocol.The FFMP for the mine also outlines the RemnantWoodland Enhancement Program (RWEP), theRehabilitation Program and the Flora and FaunaMonitoring Program.During 2008 the FFMP was reviewed internally andaudited externally by an ecologist. The revisedFFMP was submitted to the DoPI in April 2008, andapproved by the DoPI in June 2008. A furtherreview of the FFMP was completed in early 2010and subsequently re-submitted into the DoPI. At theend of the reporting period, WCPL were awaitingnotification from DoPI regarding the latest revisionof the FFMP.The WRD FFMP includes the requirements for theprotection and maintenance of the rail loopwoodland areas as part of the RWEP.The key components of the Vegetation ClearanceProtocol include the delineation of areas to becleared of remnant vegetation, pre-clearancesurveys, fauna management strategies, vegetationclearance procedures, seed collection, and salvagereuse of materials.The key components of the Threatened SpeciesManagement Protocol are site observations andsurveys, threatened species managementstrategies, consultation and reporting.General arrangement of Bioremediation SiteWith the above controls in place, the probability ofcontaminated land at WCPL is considered to be low.Any soil that becomes contaminated withhydrocarbons is reported and collected for treatmentin the new bioremediation facility.3.7 Threatened Flora andFauna3.7.1 Environmental ManagementWCPL has a Flora and Fauna Management Plan(FFMP) for the mine, and for the Wambo RailDevelopment (WRD). Both Plans have beenprepared in accordance with the developmentconsent requirements, and were approved by theDoPI in 2005. The FFMP’s document managementpractices aimed at minimising the potential impactson flora and fauna as a result of WCPL’s activities.3.7.2 Environmental PerformanceDuring the reporting period WCPL engaged aspecialist ecologist to undertake the annualecological monitoring Remnant Woodland Areasand Riparian Bend and Bank Stability Monitoring, inaccordance with the FFMP. A summary of themonitoring is in Section 3.7.2.3. In addition to this,WCPL completed Swift Parrot and RegentHoneyeater and winter bird surveys. The results ofthe winter bird survey are incorporated intoe theannual Ecological Monitoring Report, included inAppendix 2G.3.7.2.1 Pre-Clearance SurveysDuring the reporting period, several pre-clearancesurveys were undertaken in consultation withecological specialists, for mining and explorationrelated activities, including the advancing open cutinto the area known as the Montrose Pit . Under theFFMP, pre-clearance surveys identify requirementsfor additional flora and fauna managementmeasures.Page 58

2010-2011 AEMR3.7.2.2 Acacia SpeciesDuring the development of the EIS in 2003, a standof an Acacia species was found to the west of NorthWambo Creek, which was initially identified asAcacia anuera. In 2004 Terry Tame (Acacia expert)and Travis Peake (then of the Hunter CatchmentManagement Trust) concluded this stand to beAcacia pendula. However, the lack of floweringplants meant that confirmation could not beattained.The NSW Scientific Committee has made a finaldetermination to list the population of the treeAcacia pendula in the Hunter catchment as anEndangered Population in Part 2 of Schedule 1 ofthe Threatened Species Conservation Act 1995.An Acacia management plan was developed in2006. During the development of this managementplan site investigations were undertaken of theAcacia sp. on site and the known stands of Acaciapendula in Jerry’s Plains cemetery. Theseinvestigations raised questions over the correctidentification of the large stand of Acacia sp atWCPL. Due to the lack of flowering it is thought thatperhaps this plant is a sterile hybrid of Acaciapendula and Acacia homalophylla. Conclusivelyidentified Acacia pendula and these hybrid Acaciahave been found at Jerry’s Plains cemetery andacross WCPL’s site.Further detailed investigations, which included a siteinspection in April 2007 to determine the correctidentification of these Acacia species wasundertaken by HLA Envirosciences. Although thefindings to date have been inconclusive, WCPLcontinued to monitor these plants for signs offlowering during 2010-2011 so that correctidentification may be made.In 2008, investigations were undertaken with anexpert botanist during the reporting period to verify ifthe strand is actually Acacia pendula. It wasdetermined that insufficient information exists (i.e.did not flower during the reporting period again) withrespect to the genetic characteristic of this species.In accordance with Condition 16 of the Wambo CoalSMP, WCPL prepared the Acacia pendulaManagement Plan for LW Panel 4. The Acaciapendula Management Plan for LW Panel 4 wasapproved by the DTIRIS on the 13 January 2011.In accordance with WCPL’s Acacia pendulaManagement Plan for LW Panel 4 an inspectionwas completed on 15 June 2011 by an ecologist.These investigations were conducted as a duediligence precaution to determine the currentcondition of the population with regards to thehealth, recruitment, extent and habitat attributesprior to undermining. The results from that surveyconcluded the stand is generally healthy withrespect to Age Classes, Recruitment, Health,Infestations and Senescence. The stand shows thetypical attributes of a dynamic population which isself-propagating and is likely to continue to do soprovided no stochastic events impact upon the area.Underground mining activities below this stand ofAcacia species occurred during the end of thereporting period. In accordance with the Acaciapendula Management Plan for LW Panel 4, furtherdetails of all post inspections will be discussed inthe next AEMR.3.7.2.3 Remnant Woodland EnhancementProgramThe objective of the Remnant WoodlandEnhancement Program (RWEP) is to help conserveregional biodiversity, whilst enhancing the habitatavailable to flora and fauna. The RWEP will providea strategy that gives protection in perpetuity forRWEP Area A and long-term protection of RWEPAreas B and C. The RWEP also includes the areawithin the area of the WRD rail loop (see Figure3.18).During late 2009, WCPL added another area ofapproximately 50ha to the Remnant WoodlandEnhancement Program. The additional area offsetconstruction of the new South Dam. This recentoffset area is now referred to as RWEP Area D (seeFigure 3.18).2010 Annual Ecological Monitoring SummaryFlora monitoring identified 275 flora species across34 flora quadrats. Current management practiseswithin the RWEP areas of Wambo Coal Mineappear to be appropriate for the conservation offlora species. Variation evident in the results fromthe five years of monitoring is most likely related tonatural variation in species distribution, naturalvariation in species abundance and variationinherent in the sampling design, and not to currentmanagement practices. There was no evidence tosuggest that current management practices ormining activity was having any effect on the floraspecies within the RWEP areas of Wambo CoalMine.While no Swift Parrots or Regent Honeyeaters wereidentified during targeted winter bird surveys, annualsurveys for these species will continue into thefuture, particularly during years of heavy eucalyptblossom, when targeted species may occur onWambo Coal land.Page 59

2010-2011 AEMRDiurnal bird monitoring identified 78 bird speciesacross 26 survey sites, including seven threatenedspecies. Current management practices within theRWEP areas of Wambo Coal Mine appear to beappropriate for the conservation of bird species.Variation evident in the results across the years ofmonitoring is most likely related to natural variationin species diversity, natural variation in speciesabundance and variation inherent in the samplingdesign, and not to current management practises.No threatened owl species responded to callplayback surveys. Due to the large home rangearea of the target owl species and the relatively few(four) call playback sessions undertaken each year,it is not unexpected that threatened owls speciesare rarely detected.Spotlighting surveys identified the CommonBrushtail Possum as the most common arborealmammal species in RWEP areas of Wambo CoalMine. Across four years of annual monitoring onlythree arboreal mammal species have beenidentified. The Common Brushtail Possum wasidentified each year and the threatened YellowbelliedGlider and Squirrel Glider were recorded forthe first time in 2010.There is no evidence to suggest that currentmanagement practices or mining activities arehaving any negative impact on fauna species.Riparian monitoring identified Stoney Creek asbeing in good condition, and North Wambo andSouth Wambo Creeks in moderate condition.Current bank erosion problem areas are a result ofhistoric land management practices.Recommendations have been made to addressproblem erosion areas and to undertake othermanagement actions that will lead to increasedmonitoring condition scores for all three creeks..Page 60

2010-2011 AEMR3.8 Weeds3.8.1 Environmental ManagementThe FFMP details the weed control measures usedto minimise the potential for weed invasion. Theseinclude identification of weed infestations duringpre-clearance surveys, removal of weeds orapplication of approved herbicides and follow-upinspections to assess effectiveness of the weedmanagement measures implemented.Only certified personnel who have completed theChemCert Farm Chemicals User Course, theSMART Train Chemical User qualification orequivalent undertake weed control at WCPL. Allactivities are conducted in accordance with thePesticides Amendment (Records) Regulation 2002.Weed sighting sheets have been developed and aremade available to all personnel. The sighting sheetsassist with prioritising weed control works andidentifying problem areas. During the reportingperiod WCPL engaged a weed contractor to assistwith the ongoing (monthly) weed control. All areasthat are inspected and controlled are entered intoGIS database to assist in the management of weedsacross the entire site (see Figure 3.19).3.8.2 Environmental Performance3.8.2.1 Remnant Woodland EnhancementAreasA comprehensive weed control program withinRemnant Woodland Areas continued during thereporting period. The target species of the weedcontrol program included African Olive, Mother ofMillions, Creeping Pear, Tiger Pear, Purple Top,Caster Oil Plant, Galenia and African Boxthorn.Follow up spraying continued in this reportingperiod, to enhance previous spraying campaigns.Weed spraying in RWEP A and the Rail Loop areasreduced significantly the areas infested by CreepingPear. The weed control program also focussed onreducing the number of African Olive trees acrossWCPL landholdings.WCPL weed control program and continuedmonitoring will be undertaken during 2011-2012 todetermine if there is any seasonal variation in theweed species present.3.8.2.2 North Wambo, South Wambo andStoney CreeksDuring the reporting period weed control wasundertaken along potions of South Wambo Creek,North Wambo Creek and Stony Creek. Continuedmonitoring will be undertaken during 2011-2012 todetermine if there is any seasonal variation in theweed species present. All weed control work isperformed in accordance with the Cattle Carerequirements.3.8.2.3 Open Cut RehabilitationWeed control programs continued within areas ofthe Open Cut rehabilitation. Several methods ofweed control have historically been employed,including weed spraying, burying and competitionplanting.3.9 Feral Animal Control3.9.1 Environmental ManagementThe FFMP details the feral animal control measuresused to minimise the threat to native fauna andcomply with the requirements of the Rural LandsProtection Act, 1998. Programs to assess thestatus of pest populations, implementation of pestcontrol measures, implementation of mandatorypest control for any declared pests (i.e. rabbits, pigsand wild dogs) and follow-up inspections to assesseffectiveness of the control measures implementedare carried out on an annual basis.3.9.2 Environmental PerformanceDuring the reporting period WCPL completed anextensive feral animal control program. Thevertebrate pest control program was undertaken inthe winter of 2010 and summer of 2011 throughoutthe RWEP areas, around WCPL infrastructure andWCPL owned buffer lands. This vertebrate pestcontrol program will be followed up with a winterferal animal control planned for August 2011. Thevertebrate pest control program included 1080baiting, feral cat cage trapping and sandpadmonitoring.The summer 2011 baiting program saw the baituptake rate increased 11% in the winter 2010control period to 18%. This increase in baitconsumption is likely to be due to favourableclimatic conditions and juvenile litters of targetspecies highly active in the area. Foxes illustrated ahigher consumption rate of baits in comparison towild dogs. This is suggestive as foxes are prone tohave a smaller territorial area and also exhibithigher scavenger like behaviours when in search forfood. In this summer 2011 control program, foxesPage 63

2010-2011 AEMRrecorded a consumption rate of 12.8% with wilddogs exhibiting a comparison uptake of 5.7%. A wildpig trapping program was also initiated based onsightings along the Wollemi Brook. There were nowild pigs caught as a result of the trapping efforts.3.9.3 Remnant WoodlandEnhancement ProgramThe results of the vertebrate pest control programwithin the RWEP areas are described in Section3.9.2.3.10 Blasting and Vibration3.10.1 Environmental ManagementBlasting is conducted by Downer EDI BlastingServices and monitoring is conducted by WCPLpersonnel using a network of permanent blastmonitors located on site and on neighbouringproperties surrounding WCPL (Figure 3.1). Blastmonitoring was conducted at four locations aroundthe mine during the 2010-2011 reporting period.The locations of these blast monitors are as agreedby the OEH and satisfy WCPL’s regulatoryrequirements in relation to blast monitoring.EPL 529 permits WCPL a maximum groundvibration of 10 mm/second and requires that lessthan 5% of total blasts exceed 5 mm/second at anynon-mine owned residential locations. EPL 529also permits WCPL’s blasting operations amaximum of 120 dB(L) and requires less than 5% oftotal blasts exceed 115 dB(L) at any non-mineowned residential location.Every blast is designed with consideration forvibration and overpressure impacts of blasting onour neighbours, including the Undergroundoperations. In addition to the blast designs, ablasting protocol is in place which prevents blastingduring weather conditions which may adverselyaffect neighbours. The wind criteria of the blastingprotocol were modified following an incident inJanuary 2007.3.10.2 Environmental Performanceresults for each of the four monitors are illustrated inFigure 3.20 and are provided in Appendix 2E.A total of five out of the 68 blasts fired at WCPLduring the reporting period recorded levels above115 dB(L) at blast monitors located at varioussensitive receptors. WCPL was not able to meet the5% of total blasts exceeding 115 dB(L), with total of7.35% of blasts not achieving the 115 dB(L) criteria.One of the five blasts mentioned above exceededthe 120 dB(L) limit during the reporting period at124.4 dB(L). This was reported to OEH and isfurther discussed in Section 3.20.2.WCPL’s development consent specifies that blastswithin 2 km of the Wambo Homestead need to bemonitored. All 68 blasts were monitored at theHomestead regardless of the 2km trigger. Allblasting results at the Wambo Homestead arereviewed on a monthly basis by an independentstructural engineer.Any recorded overpressures at the WamboHomestead blast monitor, that exceed the EPLblasting criteria of 115dB and 120dB are notconsidered a non-compliance because the propertyis owned by the mine.There were no vibration results greater than 5mm/second at any of the monitoring sites during thereporting period (except results from the Homesteadmonitor).With the exception of two shots fired in April 2011,structural engineering reports for the WamboHomestead during the reporting period confirmedthat:All blasts recorded at the Wambo Homesteaddid not exceed the ground vibration approvallimit of 5 mm/s; andThe ground vibration levels recorded at theWambo Homestead are not expected to causestructural damage.The two shots in April 2011 which resulted inelevated ground vibration readings wereinvestigated and reported to DOPI. See Section3.13.2.1 for more information on these two shots.3.10.2.1 Blast MonitoringThere were a total of 68 blasts in the open cutduring the reporting period. All 68 blasts weremonitored with a 100% capture rate. The blastPage 64

2010-2011 AEMR3.10.2.2 Wambo Rail DevelopmentVibration MonitoringConstruction of the Wambo Coal Terminal (WCT)commenced in May 2005 and has been operationalsince June 2006. Quarterly vibration monitoring wasundertaken between 2005 and 2008 for the WRD inaccordance with DA 177-8-2004, Schedule 4,Condition 12, and the approved Wambo RailDevelopment Vibration Monitoring Program.Monitoring results from 2005 to 2008 concluded thatWRD has not increased vibration levels in theWarkworth area. In the previous reporting period(2008/2009), WCPL engaged a vibration consultantto complete a summary of all of the vibrationmonitoring results since the construction of theWCT. The summary report was sent to the DoP toseek approval to discontinue monitoring andapproval was granted in December 2008.3.11 Operational Noise3.11.1 Environmental ManagementNoise monitoring is undertaken in accordance withWCPL’s approved Noise Monitoring Program(NMP).A number of proactive management measuresdesigned to minimise noise generation fromoperations at WCPL and the WRD have beenimplemented over the reporting period including:Regular maintenance of plant and equipmentand pre-start up inspections; Positioning of portable generators andmachinery to take advantage of natural andman made barriers to mitigate sound travel;Equipment is turned off or throttled down whennot in use; Construction of noise and visual bundssurrounding the operational activities; andMinimal disturbance of vegetation between thesite and nearby residences to provide a screento mitigate sound dispersal.The noise monitoring criteria for the mine and WRDare presented in Table 3.3. The noise criteria onlyapply to noise generated from WCPL’s miningoperations, rail loop and rail loading operations.In addition to these noise criteria the Wambo railline also has rail pass-by criteria as set out inconsent DA 235/97 from SSC. These criteria arelisted in consent Condition 8 DA 235/97 and are asfollows:The applicant shall ensure noise emissions from theoperation of the JPRL when measured at anyresidence along the railway line corridor shall notexceed the following EPA criteriaa) Planning level of L Aeq24hr 55dB(A); andb) Maximum pass-by level of L Amax 85dB(A).Real Time Noise MonitoringFour real-time monitoring locations have beenestablished at representative locations to the southand north-west of WCPL.The noise environment surrounding WCPL ismonitored using four fixed remote continuous noisemonitors. The monitors are installed on propertiesidentified in the WCPL’s NMP, including Kelly (N03),Muller (N16), Thelander (N20) and the WCPLowned WA (N21).Attended Noise monitoringAttended noise monitoring for WCPL was completedat a total of six locations over the 2010-2011reporting period in accordance with the relevantdevelopment consent conditions, the NMP and theWRD Construction and Operational NoiseManagement Plan (WRD NMP) (see Figure 3.1)Page 66

Where it can bedemonstrated that direct measurement of noise from the development is impractical, the DEC may accept alternativemeans of determining compliance (see Chapter 11 of the NSW Industrial Noise Policy). The modification factors inSection 4 of the NSW Industrial Noise Policy shall also be applied to the measured noise levels where applicable.b) Noise from the development is to be measured at 1 metre from the dwelling façade to determine compliance with theL A1(1 minute) noise limits in the above table.c) The noise emission limits identified in the above table apply under meteorological conditions of: Wind speeds of up to 3 m/s at 10 metres above ground level; or Temperature inversion conditions of up to 3ºC/100m, and wind speeds of up to 2 m/s at 10 metres aboveground level.Page 67

2010-2011 AEMR3.11.2 Environmental PerformanceReal Time Noise MonitoringWCPL compile quarterly reports on monitoring datafrom four fixed SentineX continuous noisemonitoring systems adjacent to WCPL. Below is asummary of the quarterly reports for real time noisemonitoring.Q1- July to September 2010Assessment of noise impacts for the July toSeptember 2011 monitoring period indicates thatWCM complied with the noise level criteriaprescribed in the Wambo Coal NMP. Resultsindicate that environmental noise includinglivestock, barking dogs, road noise andmeteorological impacts dominate the night-timenoise environment.Where mining noise impacts were observed, someuncertainty exists in the validity of the monitoringdata. While EPL 529 excludes data influenced bystrong temperature inversion (lapse rates of3 C/100m and wind speeds up to 2 m/s), themethods available to assess atmospheric stabilityprovide conflicting evaluation as to the validity of thenoise monitoring data. The NSW Industrial NoisePolicy (INP) provides several methods forevaluation of atmospheric stability, two of which arerelevant to the meteorological monitoring dataavailable from WCM:• evaluation using the sigma-theta method; or• direct measurement of vertical temperaturegradients (over a minimum distance of 50 m).Direct measurement data available from the WCMmeteorological station monitors temperature at2 metres and 10 metres above the ground level.While this arrangement does not comply with INPrequirements (> 50m (vertical)), lapse ratesbetween +1.5 C and +3.5 C were commonlyobserved in the 2 metre and 10 metre data,suggesting that (if the trend continues above 10metres) vertical temperature gradients greater than3 C/100m may be present.Assessment of atmospheric stability by the sigmathetamethod at these times indicates the presenceof only neutral (Class D) to moderate (Class F)temperature inversion. As the sigma-theta is theonly approved method available to use (based ondata collected by the WCM meteorological station),it is considered significant amounts of datainfluenced by strong temperature inversion wereretained in the analysis.Q2 - October to December 2010Measured noise levels were found to comply withthe L Aeq,15minute criteria more than 90% of the timeat the N21 (WA) monitoring location and 98% of thetime at the N20 (Thelander) monitoring location.Detailed contribution assessment of monitoring dataat the N16 (Muller) monitoring location remainconservative, but suggest that L AeqLF,15minute noiselevels attributable to WCM operations exceeded the40dB(A) criteria approximately 14% of themonitoring period; the measured exceedence rateattributable to all environmental noise sources atthis location was approximately 47%. Review ofrecorded audio indicates passage of vehicles on theGolden Highway was the dominant noise impact atthis monitoring location.Q3 - January to March 2011Review of L A11minute results indicates that animalnoise, road noise and meteorological influences(gusting winds) dominate the L A1 noise environmentadjacent to the WCM. Mining activity was observedduring audio assessment of L A1,1minute results at theN21 (WA) and N16 (Muller) monitoring locations.The contribution from mining operations wasdetermined to be below the 50 dB(A) criteria on allbut one occasion (N16 (Muller)); on this occasion,the source of the mine noise contribution could notbe determined, and could therefore not be attributedto WCM operations.Q4- April to June 2011Measured noise levels were found to comply withthe L Aeq,15minute criteria more than 80% of the timeat the N21 (WA) monitoring location and 95% of thetime at the N20 (Thelander) monitoring location.These results, and analysis of monitoring data fromthe WCM meteorological monitoring station, areconsistent with the impacts observed during the Julyto September (2010) period. This assessmentindicates monitoring data during the winter monthsmay be subject to enhanced propagation effectsassociated with temperature inversion, which cannotbe excluded from the monitoring results on the basisof existing analysis methodologies.While mine noise impacts were observed, LAeqperiod results indicate that environmental noiseincluding insects, livestock, road noise andmeteorological impacts dominate the night-timenoise environment adjacent to the WCM.For the complete quarterly reports of real time noisemonitoring at WCPL for the reporting period, pleaserefer to Appendix 2F.Page 68

2010-2011 AEMRAttended Noise MonitoringGlobal Acoustics was engaged by WCPL to providea summary of the quarterly environmental noisesurveys conducted around the operation and theWambo rail line from 1 July 2010 to 30 June 2011.Monitoring was delayed several times duringQuarter 2, 2011 due to train scheduling and thearrival of trains coinciding with acceptablemeteorological conditions. As a result of trying tofind a suitable time to undertake monitoring, theQuarter 2 2011 survey was extended into August2011.Attended environmental noise monitoring wasundertaken on a quarterly basis at six sites duringQuarter 3 2010, and five sites during Quarter 4 2010and Quarter 1 & 2 2011 around the mine. Thesurvey purpose is to quantify and describe theexisting acoustic environment around WCPL andWRD and compare results with relevantdevelopment consent conditions or modelled EISnoise levels.Noise levels from WCPL complied with thedevelopment consent criteria or modelled noiselevels at all sites during the 2010/2011 attendedmonitoring, with the exception of N01 in Quarter 42010. At N01, an exhaust continuum was audiblethroughout the measurement, generating an LAeqof 37 dB, an exceedance of 2 dB. A surge in thecontinuum generated an LA1 1min of 41 dB.This exceedance is not considered significant asChapter 11 of the OEH ‘Industrial Noise Policy’deems a development to be in non-compliance onlywhen “the monitored noise level is more than 2 dBabove the statutory noise limit specified in theconsent or license condition.”Noise levels from WRD complied with thedevelopment consent criteria or modelled noiselevels at all sites during the 2010/2011 attendedmonitoring. It is noted that wind speeds and/ortemperature inversion conditions were at levelsgreater than which development consent conditionswould apply for WCPL and WRD activities in someinstances. In most instances, the predicted EISnoise levels were met regardless.For the complete annual report of attended noisemonitoring at WCPL for the reporting period, pleaserefer to Appendix 2F.3.12 Visual Stray LightTo minimise lighting impacts on WCPL’s neighboursthere is a plan depicting all the neighbours ondisplay in the Open Cut Examiners (OCE) office toreference for lighting plant positioning.All mobile lighting plants are strategically positionedto avoid light being directed towards our neighboursand specific lighting fixtures associated with theproduct stockpile area were adjusted in response toprevious community complaints3.12.1.1 Environmental PerformanceIn accordance with Consent Condition 86, Schedule4 of DA305-2033, WCPL completed an assessmentof all external lighting associated with the mine toAustralian Standard AS4282 (INT) 1995 – Control ofObtrusive Effects of Outdoor Lighting. Theindependent audit completed in June 2011concluded WCPL lighting did meet the requirementsof AS4282.However, during this reporting period there werefive community complaints in relation to lighting. Thecomplaints related to mobile lighting plants, whichwere providing safe lighting for night dumpingactivities on overburden dumps. In response tothese complaints, training packages, changes indumping sequences and repositioning the mobilelight plant were undertaken by the Open Cutoperations. For further details regarding communitycomplaints please refer to Section 4.2.3.13 Cultural and NaturalHeritage Conservation3.13.1 Aboriginal Heritage3.13.1.1 Environmental ManagementArchaeology and Cultural Heritage is managed inaccordance with the National Parks and Wildlife Act1974 (NPW Act), the Aboriginal Cultural HeritageConsultation Requirements for Proponents 2010(ACHCRs) and the Environmental Planning andAssessment Act 1979 (EP&A Act). The NPW Actprovides protection for Aboriginal objects or places,while the EP&A Act ensures that Aboriginal culturalheritage is properly assessed in land use planningand development. The NPW Act provides statutoryprotection for all Aboriginal heritage, places andobjects with penalties levied for breaches of the Act.This legislation is overseen by the Office ofEnvironment and Heritage (OEH). Part 6 of this Actis the relevant part concerned with Aboriginalobjects and places, with Section 86, 87, 89A andSection 90 being the most pertinent.The Aboriginal Cultural Heritage ConsultationRequirements for Proponents (ACHCR’s) wereissued by OEH on 12th April 2010. Theseconsultation requirements generally replace thePage 69

2010-2011 AEMRpreviously issued Interim Community ConsultationRequirements (ICCR) for Applicants (DEC 2004).The ACHCR guidelines apply to all AHIPapplications prepared after 12th April 2010. Forprojects commenced before the 12th April 2010,Section 1 (Q1) of the transitional arrangementsindicates that if Aboriginal consultation wascommenced prior to the 12th April 2010 (includingadvertising and notification of stakeholders), thenconsultation is to be continued under the previousICCR guidelines.Aboriginal heritage sites within the WCPL miningleases were identified and assessed during the2003 EIS. The location of sites is shown on Figure3.21.The WCPL Surface Disturbance Permit (SDP)process requires the location of the proposeddisturbance to be checked, to ensure that anarchaeological and heritage assessment has beenconducted and that any Aboriginal artefacts orobjects likely to be impacted upon have beensalvaged in accordance with the relevant permitsissued under the NPW Act, or are protected fromdisturbance.OEH released a publication entitled Due DiligenceCode of Practice for the Protection of AboriginalObjects in New South Wales on 24th September2010. This Code of Practice was developed with theexpress intention of satisfying the due diligencerequirement contained within s87(2) of the NPW Act1974. In September 2010, the NSW MineralsCouncil released a publication entitled NSWMinerals Industry Due Diligence Code of Practicefor the Protection of Aboriginal Objects which is arecognised industry specific code of practice. Duediligence inspection relates to the physicalidentification of Aboriginal objects. Communityconsultation is only required once Aboriginal objectshave been detected and if an Aboriginal HeritageImpact Permit (AHIP) is deemed necessary. TheOEH due diligence requirements are described asthe minimum standard of care required, however, itis noted within that Code of Practice that anyindustry-specific due diligence procedures of ahigher standard should be followed instead.3.13.1.2 Environmental PerformanceSalvageA Section 87/ 90 Permit (#2222) (now known as anAboriginal Heritage Impact Permit) was issued toWCPL by the DEC (later DECCW and now OEH)under the NPW Act on 20 June 2005. Inconsultation with the DECCW and local Aboriginalgroups, the DECCW granted approval to extend thepermit for an additional 5 years, expiring on the 19June 2015.Ongoing artefact analysis works associated with thesalvage programme were conducted during thereporting period in accordance with therequirements under Permit #2222. The salvageprogramme targeted sites in the approved Open Cutdisturbance area.The arrangements for the salvage operationfollowed the Interim Community ConsultationGuidelines (ICCG) issued by the DEC in 2004. Allrespondents to the ICCG process attended a siteinduction at WCPL on 12 February 2009. Themembers of the Wonnarua Aboriginal CommunityStakeholders (WACS) undertook the salvage andexcavation works under the guidance of anarchaeologist.Temporary Keeping PlaceThe WACS, WCPL and the Archaeologist from RPSHSO met at WCPL in February 2009 and agreed ona Temporary Keeping Place that was subsequentlyapproved by the DECCW on 14 July 2009. Allartefacts salvaged during the operation are stored atthe Temporary Keeping Place under Permit #3130for Care and Control of Aboriginal Objects Salvagedunder Section 87/ 90 permits #2085 and #2222 inaccordance with the NPW Act (1974 as amended).During May and June 2010, several salvageprograms were undertaken in accordance with therequirements under Permit #2222. The salvageprograms targeted sites in the north western portionof the approved Open Cut disturbance area.3.13.1.3 Aboriginal Cultural HeritageConservation Agreement –Remnant Woodland EnhancementArea (A)During the last reporting period WCPL engaged anArchaeologist to establish an Aboriginal CulturalHeritage Conservation Agreement for RWEP AreaA. The preparation of this document involvedconsultation with local Aboriginal Groups and theOEH and was developed in accordance withDA305-7-2003, Schedule 4, Consent Condition 51.The agreement establishes protocols formaintaining the cultural significance within RWEPArea A.Page 70

2010-2011 AEMR3.13.2 European Heritage3.13.2.1 Environmental ManagementTier 2: Those tasks that will require approvalfrom the Heritage Branch and/or furtherassessment and planning by a suitably qualifiedarchitectural/heritage consultant prior tocommencement.On the 23 December the annual inspection of theWambo Homestead Complex (WHC) wasundertaken by a structural engineer. The objectiveof the assessment was to determine if any damageto the Wambo Homestead buildings was attributedto ground vibration. In the opinion of the structuralengineer, blasting activities at WCPL were notcontributing to damage to the Homestead.The annual archival photographic record of theWHC was undertaken in December 2010. Copiesof these photos were sent to NSW Heritage Office,DoPI and SSC in February 2011.In accordance with the Conservation ManagementPlan for the WHC, routine pest inspections andbaiting programs for termites and rodents continued.An upgrade of the fire suppression system was alsocompleted.Voluntary Action PlanOn 02 December 2010, representatives of WCPL,DoPI and the Heritage Branch conducted aninspection of the Wambo Homestead (WH), todetermine compliance with Condition 59 of theWambo Development Consent (DA 305-7-2003).During the inspection it was identified that, althoughWCPL had completed maintenance activitiesincluding yard maintenance, installation of a firesuppression system and other maintenanceactivities listed in the Conservation ManagementPlan (CMP), it was also identified that someadditional works would improve WH conservation.As a result WCPL, committed to a Voluntary ActionPlan (VAP) to work with the Heritage Council to gainapproval for the proposed VAP works. Completionof these works would ensure continuedmaintenance of the WH in accordance withCondition 59.The maintenance tasks and activities committed toin the VAP were identified during the inspection.These tasks, and proposed timings for completion,are presented in Table 1. The tasks/activities weredivided into two tiers:Tier 1: Those tasks that can be completedwithout further assessment or approval; andThe following summary of tasks and activities werecompleted as part of Wambo voluntary Action Planfor the maintenance of the Wambo HomesteadComplex during the reporting period, whichincluded:Tier 11. Studmaster’s Cottage:Inspect and maintain existing weather proofcoverings.2. Butcher’s Hut:Trim adjacent tree (to south) to reduce potential forimpact on Hut.3.

The revision of the CMP for theWHC is a major activity planned for the upcomingreporting year.Blast Vibration StudyWambo currently monitors and reports on open cutblasting ground vibration, and potential impacts onthe WHC. Ground vibration is currently monitoredand assessed based on peak particle velocity (ppv),measured in mm per second.In response to concerns expressed about theaccuracy of assessing blast vibration impacts basedonly on ppv, WCPL engaged a specialist engineer(Bill Jordan & Associates) to investigate whetherblast ground wave frequency, as well as ppv, is amore accurate indicator of potential vibrationimpacts. It has been previously been shown thatmovement of the building or its parts can be greatlyamplified compared with the blast wave if resonantfrequencies are excited in the building.The results of this study will allow a betterappreciation of the risks posed to the WamboHomestead buildings from blast ground vibration,and lead to more accurate setting of blast limits, andblast design, which will take the resultingfrequencies into account.The study was ongoing at the completion of thereporting period. Outcomes of the study will beincorporated into the Wambo Blast MonitoringProgram, and reported in the next AEMR.Blast AssessmentWCPL forwards all blast monitoring results for shotsfired within 2km of WHC to an independent engineerfor assessment. In April 2011, two shots in thenearby Homestead pit resulted in ground vibrationresults of 13.6 & 11.9 mm/s at the HomesteadMonitor. As well as the site based investigation, anindependent engineer was engaged to conduct astructural inspection of the Homestead to identifyany impacts from these blasts. The inspectionidentified superficial cracking in the New Houseceiling plaster, but no impacts to the structuralintegrity of the WHC buildings. A copy of this reportwas provided to DOPI.3.14 Spontaneous Combustion3.14.1 UndergroundThere were no spontaneous combustion incidents atthe Underground during the reporting period.Inspections for spontaneous combustion form partof the Underground inspection system. WCPL willcontinue to monitor for signs of spontaneouscombustion in the next reporting period.The Underground mine atmosphere is monitoredcontinuously in the main fan return. Monitoringresults and trends are displayed in the control room.Any abnormal readings trigger an audible and visualalarm. All monitoring equipment is tested andcalibrated regularly.3.14.2 Open CutAs reported in previous AEMR’s, spontaneouscombustion (spon comb activity within the Open Cutoperations is limited to one location. The spon combis located on the north western side of the HunterPit. This incident is considered minor and is beingmonitored by WCPL operations. Inspections forspontaneous combustion form part of the Open Cutinspection program.3.14.3 CHPPThere were no spontaneous combustion incidents atthe CHPP during the reporting period. Inspectionsfor spontaneous combustion form part of the CHPPinspection program.3.15 Bushfire Management3.15.1 Environmental ManagementThe Bushfire Management Plan (BFMP) wasoriginally approved by the NSW Rural Fire Service(NSWRFS) and SSC in 2005. This planincorporates both an identification of likely bushfirePage 73

2010-2011 AEMRhazards on the site, and an assessment of the risksthose hazards represent. Based on the hazard leveland the associated risk level, fire managementstrategies for the site have been formulated.In February 2008, the BMP was reviewed inconsultation with the NSWRFS and subsequentlyapproved on 1 July 2008. The revised BMP wassent to the SSC in accordance with ConsentCondition 93, Schedule 4 of DA305-7-2003.In December 2010, the NSWRFS completed anassessment of various grassland and bushlandareas within WCPL’s landholdings regardingbushfire hazards. WCPL are currently reviewing theassessment with the NSWRFS.3.15.2 Environmental PerformanceThe bushfire trails around the WCPL boundary wereinspected during the reporting period. Sections ofWCPL internal bush tracks that form part of the FireTrail running along the western boundary of theWollemi National Park were maintained. Existingsignage on several main access gates werereplaced, detailing land ownership and emergencycontact numbers in case of fire outbreak.There were no bushfires within WCPL owned landduring the reporting period.3.16 Mine SubsidenceWCPL’s Underground operates under an approvedSubsidence Management Plan (SMP). This SMPcovers underground mining activities for the nextseven years for Longwall Panels 1 through to 6 (LW1-6), and includes an assessment of environmentalimpacts associated with subsidence.Longwall underground mining commenced inLongwall Panel 1 (LW1) in October 2007 and wascompleted in January 2009. Longwall miningcommenced LW2 during March 2009. In December2010, extraction of Longwall Panel 3 (LW3) wascompleted, with production of Longwall Panel 4(LW4) underway in January 2011. At the end of thereporting period LW4 had retreated 1,950m. Thecompletion of LW4 is expected in October 2011.Subsidence monitoring is currently undertaken forlongwall panels in accordance with WCPL’sapproved SMP. The results of subsidencemonitoring are reported to the DII as per therequirements in the SMP.Subsidence in the South Wambo and Stony Creekareas is further discussed in Section 5.1.2 of thisreport.Since 2006, Baseline Riparian Vegetation and BedBank Stability Monitoring Programs were initiated inNorth Wambo, South Wambo and Stony Creeks.The Riparian Vegetation and Bed Bank StabilityMonitoring Program continued in during the 20010-2011reporting period. The monitoring programs aredesigned to obtain a greater understanding of anysubsidence related impacts on the riparianenvironment.3.17 HydrocarbonContaminationAny soil that becomes contaminated byhydrocarbons is managed on site. All the necessaryinformation regarding soil contamination incidents,are captured in relevant Wambo EnvironmentalIncident Reports.As discussed in Section 3.6.1, WCPL and DownerEDI were finalising procedures and location of thenew bioremediation site within the Open Cut duringthe last reporting period. At the end of this reportingperiod, the facility was opened to accept and treathydrocarbon contaminated soil material. Inaccordance with the operating procedure for thebioremediation facility, contaminated soil fromWCPL operation is placed within segregated bays,where the material is treated and sampled over timeuntil laboratory results determine the materialsuitable for removal and replacement back into theopen cut pit.3.18 Methane Drainage/VentilationFor LW2 and the first half of LW3 operations theUnderground was ventilated by both relocatedWollemi axial fans operating in parallel atapproximately 190 m 3 /s at 2,000 Pascals. Methanelevels at these main fans averaged 0.9 % = 1710litres / second.With the commencement of LW2 operations it wasapparent that the Longwall gas make exceeded thecapacity of the relocated Wollemi axial fans andwork began on a project to upgrade the mine’sventilation infrastructure. Two larger fans werepurchased to replace the two Wollemi axial fans inin late 2010. The new fans have made a dramaticimprovement (50%) to ventilation quantities in theDevelopment panels and a significant increase(20%) to the Longwall district ventilation quantities.Page 74

2010-2011 AEMRWith the commencement of LW4 operations in early2011 the Longwall has seen a reduction in gasdelays compared to LW3. Methane emissions havevaried throughout the 2010-2011 reporting periodfrom 910l/s to 2040l/s depending on LW productionand gas zone, with an average of 1580l/s.The Wollemi mine remains unsealed but not activelyventilated. An inspection of the mine in July 2010showed there is approximately 5 m 3 /s of naturalventilation with a gas make of approximately 10litres /second.3.18.1 Greenhouse GasIn accordance with the requirements of the NationalGreenhouse and Energy Reporting Act 2007(NGERS), WCPL report each year the company’s: direct greenhouse gas emissions; total energy produced; and total energy consumed.At the time of writing the AEMR, the 2010-2011NGERS report was not finalised. A summary of thegreenhouse gas (GHG) emissions and energyconsumed from the 2009-2010 reporting period areprovided below. A summary of the 2010-2011 GHGemissions will be provided in the next AEMR.Scope 1: 814,520 (t CO 2 - e)Scope 2: 30,300 (t CO 2 - e)Energy Consumed: 1,066,519 (GJ)Energy Produced: 133,085,133 (GJ)Although WCPL is planning to increase coalproduction in the immediate future, management ofGHG emissions will be achieved through increasedenergy efficiency across the operation. The keyfocus of energy efficiency management at WCPL isduring the business planning phase. During projectplanning, consideration is given to potential energyconsumption of project components, and theavailability and practicality of more energy efficientalternatives.WCPL participates in the Federal Government’senergy Efficiency Opportunities (EEO) program. Aspart of that program, WCPL has conducted asystematic review of energy usage across theoperation, and identified areas for potential energyefficiency improvement. Energy efficiency measureshave subsequently been implemented, such as thereplacement of underground lighting with moreenergy efficient LED lighting.Regular scheduled maintenance of equipment andplant is also a key component of maintainingoperational energy efficiency.An enterprise-wide strategy for managing methaneemissions is being developed by Peabody EnergyAustralia.3.19 Public SafetyPublic safety is managed through theimplementation of safety systems and daily securityinspections. Fencing, signposting and lockedexternal gates form part of the safety measure toensure the safety of the public. A contractedsecurity service patrols the mine site andsurrounding areas. There were no incidentsregarding public safety during the reporting period.3.19.1 United Colliery ActivitiesUnited Collieries (United) ceased Longwall miningbeneath WCPL land during this reporting period.The last of United’s coal was loaded by rail on 27May 2010. United are currently under care andmaintenance program. Previously installedventilation boreholes that were maintained byUnited personnel, have now been decommissioned.United are still conducting exploration andenvironmental monitoring activities on WCPL ownedland.3.20 Reportable EnvironmentalIncidents3.20.1 Environmental ManagementEnvironmental incidents are managed inaccordance with WCPL’s Environmental IncidentResponse Procedure. All environmental incidentsare recorded on the Environmental Incident ReportForm which is required to be closed off by theEnvironmental Department. Incidents classificationsare as follows:Minor (Category 1)Minor incidents are those that cause negligibleactual impact on the environment, are readilycontrolled by established procedures (for example:small hydrocarbon spills in a non-sensitiveenvironment that are able to be immediatelycleaned up).Serious (Category 2)Incidents categorised as serious are those thatcause localised, reversible damage to theenvironment, for example: hydrocarbons spills in anon-sensitive environment and/or contained areaand saline water discharge.Major (Category 3)Incidents categorised as significant are those thathave actual or potential severe damage to theenvironment with the potential to result inenvironmental liability, regulatory intervention and/orsignificant community concern or actual damagePage 75

2010-2011 AEMRthat will require significant remediation/management.3.20.2 Environmental PerformanceDuring the reporting period WCPL recorded a totalof seventeen environmental incidents (two morethan reported in 2009-2010), of which there weretwelve Category 1 incidents and five Category 2incidents (Appendix 3). The Category 1 incidentsincluded small hydrocarbon spills contained withinthe open cut pit and positioning of mobile lightingplants.In accordance with WCPL’s statutory obligations,the OEH were informed of one of the Category 2incidents in relation to an over pressure exceedencefrom a blast event as described further on. WCPLreceived a penalty infringement notice (PIN) inaccordance with the POEO Act regarding theexceedance of WCPL’s EPL blasting limit of 120dBon the 17/02/2011.Category 2 – Overpressure exceedanceOn the 17 February 2011, WCPL informed theDECCW that the Muller Blast Monitor (located onthe land of a neighbouring property owner) hadrecorded an overpressure measurement of 124.4dB for a blast which occurred at approximately3.35pm. WCPL registered the incident via theDECCW Environmental Pollution Hotline at 5.40pm(DECCW reference number not provided as callwas logged after hours).No community complaints were received in relationto this incident. Upon receipt of the blast monitoringresults, Wambo commenced an investigation intothe incident.The atmospheric conditions were unfavourable atthe time of firing, with high humidity levels, overcastconditions and a change in the wind direction at thetime of firing. The wind conditions were withinWambo’s internal wind direction/speed guidelineswhen last checked by the blast controller prior tofiring. The prevailing weather conditions are thoughtto have contributed to the elevated overpressurelevel due the direction of the wind, the temperatureinversion readings and the overcast weather with alow cloud base.Future preventative actions will include: The use of slower timings when firing on thisorientation (42ms instead of 17ms); The use of new air overpressure modeling toolsto analyse the reinforcement patterns whendesigning the pattern tie in;Smaller blasts, so that there are fewer holesavailable to reinforce the pressure front, whilstalso reducing the stochastic nature of thesystem by minimising the timing scatter; andContinued monitoring of weather parameters atthe time of firing and delay of shots until morefavourable conditions prevail.3.21 Independent AuditIn accordance with Consent Condition 7, Schedule6 of DA305-7-2003, WCPL completed anindependent environmental audit to assess theperformance of the operation and whether theoperation is complying with its relevant developmentconsents, EPL or mining leases. The audit occurredduring the 7 th to the 10 th June 2011.In the opinion of the auditors, the documentation,reporting and activities at the WCPL generallydemonstrated a high degree of compliance with theconditions attached to the current consent andapprovals granted for the project. However therewere a number of recommendations provided inrelation to management plans and programs toaddress specific requirements within the consentand/or approval conditions. For a summary of theaudit findings please refer to Appendix 6 of thisAEMR.4.0 Community Relations4.1 Employment StatusThere were approximately 842 personnel, includingcontractors, employed at WCPL at the end of thereporting period. This is an overall increase ofapproximately 17% from the previous reportingperiod and the result of additional contractpersonnel employed in the Open Cut andUnderground. Downer EDI, who are contracted byWCPL to undertake the Open Cut mining, employeda total of 353 personnel, an increase ofapproximately 6% compared with the previousreporting period. The increase of Open Cutcontractors was in response to increasingproduction requirements. The total number ofWCPL employees, including contractors, was 489 at30 June 2011 an increase of approximately 24%compared to the previous reporting period. Thebreakdown of employee numbers is presented inTable 4.1.4.2 Environmental ComplaintsWCPL received a total of thirty five communitycomplaints. A total of twenty community complaintswere from the one community member and a total ofPage 76

2010-2011 AEMRfive complaints recorded from another communitymember during the 2010-2011 reporting period. Atotal of seventeen complaints were registeredthrough WCPL complaints hotline, with oneanonymous complaint via the OEH Hotline. Anumber of the community complaints related tonoise and lighting enquiries (Figure 4.1). Allcommunity complaints were managed inaccordance with WCPL’s Community ComplaintsProcedure.A comparison between the numbers of complaintsreceived this year with those received in previousyears is presented in Table 4.2.

2010-2011 AEMR4.3 Community Liaison4.3.1 Community ConsultationDuring the reporting period WCPL held threeCommunity Consultative Committee (CCC)meetings. These meetings were conducted on; 22 nd July 2010;18 th October 2010; and 29 th March 2011.Community representatives act as the point ofcontact between the mine and the community. Thecommittee is made up of residents from the Jerry’sPlains, Warkworth and South Wambo areas,representatives of SSC and WCPL and is chairedby an independent person. The DoPI endorsed thecomposition of the committee in December 2005.There were two publications of the Wambo CoalEnvironment and Community Newsletter during thereporting period. These were distributed tohouseholds, the CCC and the workforce in August2010. The newsletter is intended to keep thecommunity informed about WCPL activities.4.3.2 Community ContributionsAs part of our commitment to the local community,WCPL provided financial assistance for a number ofcommunity activities. Projects and groupssponsored included, but not limited to:Singleton LegacySydney to Wollongong Charity Ride forMultiple SclerosisSingleton Retired MineworkersSingleton Hall of FameGiggle Ball – Camp QualityOxfamJerry’s Plains Public SchoolWestpac Rescue HelicopterSingleton Amateur Swimming ClubSingleton Chamber of Commerce & IndustrySingleton June Touch Football AssociationNAIDOC Family Fun Day; andNSW Streetsmart Handbook.4.3.3 Community ProgramsLanguage ProgramWCPL continued support through the languageprogram for Jerrys Plains Public School. Thelanguage program was developed in consultationwith the schools Principal and teaching staff duringthe second half of 2008. After securing a highlyqualified speech pathologist to work with thestudents at Jerrys Plains Public School, theimplementation of the program commenced duringTerm 1 of 2009.The language program operates in the school fornine hours each Tuesday. The program involved aspeech and language assessment for each of thestudents. The assessment process iscomprehensive, taking several hours for eachstudent.In collaboration with the school Principal, twomeetings were organised so that interested parentscould learn about the program and how to bestassist their children with respect to speech andlanguage skills at home. The language program hasbeen well received and is set to continue during thenext reporting period.Singleton Public SchoolWCPL entered into a partnership with SingletonPublic School to enhance the school grounds andgardens through a native vegetation landscapingprogram. This program is considered the initialstage of a more widely scoped environmentaleducation program to be developed in consultationwith the wider school community.The first phase of the program involved theestablishment of a native bush tucker garden thatthe children will be responsible for. The plantingcommenced during the last reporting period in May2010, with WCPL personnel present to assist thechildren.Towards the end of 2010, the second phase of theprogram was undertaken with the completion ofseveral garden enhancement projects to existinggardens around the school.Page 80

2010-2011 AEMRTopsoil stripped ahead of mining will be applied tothe reshaped surface in an even layer generally notless than 100mm. Topsoil is placed using reardump haul trucks, or ejector trucks, and spread withdozers or graders. Once spread, the topsoil surfacewill be disc or chisel cultivated to create a texturedsurface which assists in trapping surface runoff,provides seed entrapments and createsmicroclimates favourable for seed germination.Where biosolids are used, cultivation also integratesthe topdressing material, which is a requirement ofthe EPA biosolids handling guidelines.Following surface preparation, vegetationestablishment across the rehabilitated area iscommenced. The aim of revegetation is to minimiseerosion and facilitate the development of the postminingland-use, be it agricultural production orhabitat/ecosystem enhancement.5.1.1.1 Rehabilitation PerformanceDuring the previous reporting period, an Open CutMOP was approved for the period of 2010-2016.The Open Cut MOP covers all aspects of the OpenCut operations including mining, rehabilitation andtailings management.The total hectares of disturbance and rehabilitationat the commencement of the new MOP period (July2010) was 998.8ha and 270.3ha, respectively.Existing rehabilitated areas include the Whynot,Low-wall and Ridge Dump areas, RL160 Dump,Charlies Hole, Wombat Hill, and Radio Shack in thecurrent Open Cut plus older rehabilitation fromprevious Open Cuts.During the previous reporting period, approximately84.4ha was rehabilitated within the Open Cut. Thisessentially accounted for all available dump areaready for reshaping and rehabilitation. Furtherrehabilitation planned for the 2010-2011 reportingperiod was reliant on the completion of overburdendumps, particularly in the Rug/ Ridge dump area.Due to delays in overburden removal from theHomestead Pit (which was being placed on the Rug/Ridge dump), no significant dump areas wereavailable for reshaping, and no open cutrehabilitation was completed during the period.The major rehabilitation maintenance project wasthe remediation on the North Wambo CreekDiversion (NWC Diversion). Remedial works werecompleted between April and June 2011 andincluded the repair of several failed creek banks,wash outs, rock armoured structures and vehiclecrossing points (as listed in Table 5.2 and detailedin Section 5.1.3).5.1.1.2 North East Tailings DamThe rehabilitation of the area known as the NorthEast Tailings Dam (NETD) has been established asa stand alone project within Peabody’s Wambo CoalOperation. Initial works commenced at the NETDduring the 2008/2009 AEMR reporting period. Thedam, which was discontinued as an active disposalsite in 2004 following Department Approval underSection 127, has been the subject of a number ofstudies to identify a safe and viable method ofcapping the relatively weak surface. WCPL havebeen working together with Australian TailingsConsultants to develop a capping strategy utilisingreinforced geogrid and controlled layers of coarsereject and overburden placed by specialist lowground pressure equipment.The scope of the NETD capping project is torehabilitate the 1220m long by 200m widedecommissioned tailings storage facility.WCPL have investigated and evaluated the cappingmethod utilising purpose built low ground pressureequipment, in conjunction with Geotextilereinforcement. Extensive design works have beenundertaken to develop the concept and provideengineered solutions to cap the weak tailingssurface. The design has considered the strength ofthe current crust (verified through Shear VaneTesting), the equipment to be used and the cappingmaterial to determine the reinforcement and theplacement method required to ensure the safety ofthis operation.The planned rehabilitation for next year is 49 ha.This work is planned for the Rug/ Ridge Dump.All disused tailings dams are rehabilitated with theexception of the North East Tailings Dam, which iscurrently being capped for rehabilitation (seeSection 5.1.1.1).Page 84

2010-2011 AEMRNETD Rehabilitation works using low press groundequipmentPlacement of the initial rejects layer has continuedwith additional small dozers sourced. Progress hasbeen slow due to the weak surface with the crust rewettingas the equipment traverses, however arepeatable process has now been demonstratedand productivity is improvingDuring the reporting period, heavy rain in early June2011 caused major ponds to form on the damsurface which suspended work activity. Pumpingcontinued throughout the month with the majority ofwater removed. As a result of the water on thesurface no placement of fabric or rejects occurredduring the month, it is anticipated access will beregained in early July 2011.Approximately 55% of the dam surface is coveredwith a layer of rejects. The target is to completerejects placement on 100% of the dam by the end of2011. The design Consultants ATC Williams visitedsite this month to review progress. Whilst there wasno activity on the dam, it was recommended workproceed as soon as the surface was accessible.NETD Rehabilitation works in progress5.1.2 Rail LineRehabilitation was progressively completed on theWambo Rail Development (WRD) following thecompletion of construction activities. The primaryaims of this rehabilitation was to allow theregeneration of native flora species on the site,maintain the structural stability of the land, preventerosion and sedimentation, and provide naturalscreening, where possible, to maintain the visualamenity of the WRD.During the reporting period, Wambo engaged theservices of a horticulturist to complete anassessment of a section of tree screen along theWRD. As a result of the tree screen assessment,WCPL completed a number of therecommendations, including additional 500 treeplantings, weed control and protective signage.Monthly follow up inspections after the works notedapproximately 70% of the newly planted trees hadsurvived.NETD Rehabilitation Status as of June 2010Continued monitoring of the rehabilitation and treemaintenance works will continue throughout 2011-2012 reporting period.5.1.3 NWC DiversionFollowing Stage 2 completion of the NWC Diversionconstruction works, all disturbed areas wererehabilitated in 2008/2009. Rehabilitation consistedgenerally of topsoil application, application of soilameliorants, ripping, seeding (mainly a pastureseedmix), and strategic tubestock planting toprovide long-term bank stabilisation. Revegetationusing hydromulching was also undertaken onsteeper batters.NETD Rehabilitation Status as of June 2011Following the first two flows, or discharges, throughStage 2 of the NWC Diversion in February and April2009, an assessment of diversion condition andbank stability was undertaken. The diversion wasinspected by the hydrological consultants whoPage 85

2010-2011 AEMRdesigned the diversion (Gilbert and Associates) anda Hunter Valley based consultancy that specialisesin rehabilitation and erosion control (GSSEnvironmental). The two inspection reports (GSSE,October 2009, and Gilbert & Associates, September2009) identified several areas requiring remedialattention.During the reporting period, WCPL preparedtenders for the remedial rehabilitation works withinStage 2 NWC Diversion, based on therecommendations provided from both GSSE andGilbert’s. After completing the Tendering processand awarding contracts, rehabilitation works withinStage 2 of the NWC Diversion commenced in April2011, with works completed during June 2011.Planning for Stage 3, the final stage of the NWCDiversion, commenced during 2010-2011. Stage 3has a construction zone of approximately 1.8km,which includes approximately 2.83km of replicatedcreek line. The current project program is twelvemonths with a start date in August 2011 and acompletion date estimated during July 2012. Detailsof the completed NWC Diversion will be reported inthe next AEMR.5.2 Rehabilitation Trials andResearchDuring the previous reporting period, WCPLcommenced incorporating biosoilds into the OpenCut rehabilitation program. A wider application areawas planned for the current reporting period, as wellas trial application of organic compost material. Asno rehabilitation was completed during this reportingperiod, application of biosoilds and organic compostis expected to occur during the next reportingperiod. An update on the biosoild application will beprovided in the next AEMR.Supplementary planting of a native grass speciesseed mix, in areas of patchy tree establishment, isalso planned for the next reporting period.The use of mobile tree mulching plant is planned forthe next reporting period. After identification andseparate recovery of timber and habitat trees, themulcher will mulch trees in situ, leaving a blanket ofmulch, which assists with dust suppression anderosion control, as well as providing a source oforganic matter in the stripped topsoil.5.3 Rehabilitation MonitoringDuring the reporting period a program of worksassociated with the monitoring of revegetateddisturbed riparian lands utilising the CSIROdeveloped Ecosystem Function Analysis (EFA)monitoring tool was undertaken. A separate surveyand report has been prepared for the monitoring ofrehabilitated areas associated with the Open Cutareas.The data that has been derived from the monitoringprogram provides a scientifically robust platformagainst which the effectiveness of rehabilitationtechniques can be assessed and where applicableamended, with a view to achieving sustainablevegetation communities on disturbed landscapes.The purpose of the assessment is to determinewhether rehabilitated areas are on a trajectorytoward self sustainability and functionality.The riparian areas surveyed included South WamboCreek and North Wambo Creek downstream of theOpen Cut offices. The second component of theriparian monitoring program commenced in 2008and focused on the North Wambo Creek Diversionrehabilitation works.5.3.1.1 Ecosystem Function AnalysisSummaryOpen Cut EFARPS was engaged by WCPL to undertake the 2010EFA monitoring of 14 previously established opencut EFA transects. Twelve EFA transects wereestablished in 2006 comprising:Six pasture rehabilitation transects;Four woodland rehabilitation transects;One pasture analogue transect; andOne woodland analogue transect.A further two pasture rehabilitation transects werecreated in 2008. During 2009 two pasturerehabilitation transects were repositioned to morerepresentative pasture rehabilitation locations.During 2010 six new transects were established,comprising:Two pasture analogue transects;Two woodland analogue transects; andTwo pasture rehabilitation transects.The total of 20 EFA transects were investigatedduring 2010 and comprised:Three analogue woodland transects;Four rehabilitation woodland transects;Three analogue pasture transects; andTen rehabilitation pasture transects.With the exception of two transects all other pasturerehabilitation transects recorded LFA score similarto the analogue transects in 2010 suggesting that,at least during 2010, many of the rehabilitationPage 86

2010-2011 AEMRtransects had a similar landscape function to thetarget analogue transects. Continued sampling willbe required to determine whether the rehabilitationanalogue sites will continue to exhibit such highscores during future years, particularly those ofharsher climatic conditions. Only when rehabilitationsites record similar or better LFA scores thananalogues sites, over a range of years and seasonalconditions, can the rehabilitation works beconsidered a success.or other soil characteristics that may vary along thelength of the NWCD.Vegetation dynamics and habitat complexity scoreswere approximately similar between 2009 and 2010.Recommendations have been made to improve theinterpretability of data collected on disturbancefactors present during sampling.Woodland rehabilitation transects appear to betrending towards the analogue values. Scores at theanalogue transects were approximately consistentwith the rehabilitation transect scores however, allother LFA components were lower at rehabilitationthan analogue transects. Overall LFA analysisindicates that the woodland rehabilitation transectsare approaching, but have not yet demonstrated,LFA values characteristic of target woodlandcommunities. However, the general pattern ofincrease in LFA parameters suggests that therehabilitation woodland transects are improvingtowards the analogue goal.Riparian EFARPS was engaged by WCPL to undertake the 2010EFA monitoring of 12 previously established riparianEFA transects. This report presents the results ofthe third year of monitoring of rehabilitation worksalong the North Wambo Creek Diversion (NWCD).The NWCD was completed in August 2008 and EFAmonitoring of 10 rehabilitation transects began inthe October 2008 (ENSR, 2009). Two furthertransects (one analogue and one rehab) werepreviously established in 2006 as part of previousEFA monitoring of open cut rehabilitation transects(HLA, 2006).In 2010, two new analogue sites were establishedalong North Wambo Creek to bring the total numberof analogue sites to three (as recommended in the2009 report). Also in 2010, rehabilitation transect14R was moved to a more suitable location, asrecommended in the 2009 report.LFA scores were either relatively constant ordeclined slightly in 2010. Similarity in scores waslikely due to the continued presence of the tallgrassland along NWCD. The reasons for declines insome LFA scores were unknown but were related toa declining ability of water to infiltrate the soil and areduced level of nutrient cycling via litterdecomposition. These scores will be continued tobe monitored closely to identify possible causes infutures years.Along the approximate 2.5 km length (straight line)of the NWCD there was a general pattern ofdeclining LFA scores from upstream to downstream.As the good season for grass growth was commonto all NWCD transects, the reason for thegeographic variation in scores was unknown butmay be related to differences in soil type, soil depthPage 87

EXECUTIVE SUMMARYGlobal Acoustics was engaged by Wambo Coal Pty Ltd to provide a summary of thequarterly environmental noise surveys conducted around Wambo Coal Mine (WCM), and theWambo Coal Rail Spur (WCRS) from 1 July 2010 to 30 June 2011.Monitoring was delayed several times during Quarter 2, 2011 due to train scheduling and thearrival of trains coinciding with acceptable meteorological conditions. As a result of trying tofind a suitable time to undertake WCRS monitoring, the Quarter 2 2011 survey was extendedinto August 2011.WCM was granted consent (DA 305-7-2003) in February 2004, which enables the extension ofcurrent open cut and underground mining operations.The WCRS consists of two Development Applications (DA’s):The Wambo Rail Loop (DA 177-8-2004); and The Wambo Rail Line (DA 235/97).The relevant sections of these consents are reproduced in Appendix A.Attended environmental noise monitoring described in this report was undertaken on aquarterly basis at six sites during Quarter 3 2010, and five sites during Quarter 4 2010 andQuarter 1 and 2 2011 around the mine. The survey purpose is to quantify and describe theexisting acoustic environment around WCM and WCRS and compare results with relevantdevelopment consent conditions or modelled EIS noise levels.Noise levels from WCM complied with the development consent criteria or modelled noiselevels at all sites during the 2010/2011 attended monitoring, with the exception of N01 inQuarter 4 2010. At N01, an exhaust continuum was audible throughout the measurement,generating an L Aeq of 37 dB, an exceedance of 2 dB. A surge in the continuum generated anL A1,1min of 41 dB.This exceedance is not considered significant as Chapter 11 of the OEH ‘Industrial NoisePolicy’ deems a development to be in non-compliance only when “the monitored noise level ismore than 2 dB above the statutory noise limit specified in the consent or license condition.”Noise levels from WCRS complied with the development consent criteria or modelled noiselevels at all sites during the 2010/2011 attended monitoring.It is noted that wind speeds and/or temperature inversion conditions were at levels greaterthan which development consent conditions would apply for WCM and WCRS activities insome instances. In most instances, the predicted EIS noise levels were met regardless.11263_R01.docPage ii

Six train passes (three loaded, and three empty) were measured at the Dyson property duringQuarter 2, 2011. Rail pass-by L Amax and L Aeq,24 hour results were less than relevant limits.11263_R01.docPage iii

1 INTRODUCTION1.1 BackgroundGlobal Acoustics was engaged by Wambo Coal Pty Ltd to provide a summary of thequarterly environmental noise surveys conducted around Wambo Coal Mine (WCM), and theWambo Coal Rail Spur (WCRS) from 1 July 2010 to 30 June 2011.Monitoring was delayed several times during Quarter 2, 2011 due to train scheduling and thearrival of trains coinciding with acceptable meteorological conditions. As a result of trying tofind a suitable time to undertake WCRS monitoring, the Quarter 2 2011 survey was extendedinto August 2011.The spur and mine operate under separate development consents and have been monitoredseparately. Reporting, however, has been combined in this document.Wambo Coal operates both open cut and underground mining operations from their mine atWarkworth, NSW. The open cut operations include use of heavy mobile equipment in opencut pits, on haul roads and on waste rock emplacements. The underground operations havesurface facilities. Both operations utilise a coal handling and preparation plant (CHPP)including conveyors, bins and other material-handling infrastructure.The WCRS is located between Mt Thorley and Warkworth Village, New South Wales (asshown in Figure 1) and includes the following components:a product coal stockpile and reclaim area, product coal conveyer, train loadout bin, railloop and a rail spur from the Wambo Coal Mine to Mount Thorley; andrail transport of product coal to the market, an intermittent activity that can take place atanytime.Attended environmental noise monitoring described in this report was undertaken on aquarterly basis at six sites during Quarter 3 2010, and five sites during Quarter 4 2010 andQuarter 1 and 2 2011 around the mine. Monitoring was not undertaken at N22 after Quarter3 2010 due to a change of ownership. Figure 1 shows the monitoring locations.Three of the six monitoring locations are within the Noise Affectation Zone, as identified inEIS reports (Wambo Development Project EIS (Resource Strategies, 2003), and Jerrys Plains CoalTerminal and Rail Line Environmental Impact Statement and Statement of Environmental Effects(CMPS&F, 1997)); as such, noise criteria do not apply directly to these properties. For theselocations, measured noise levels from WCM and WCRS are compared against EIS modellednoise results. Compliance with modelled noise levels at these nearest receptors indicatescompliance with development consent criteria at properties further away is likely.11263_R01.docPage 1

The survey purpose is to quantify and describe the existing acoustic environment aroundWCM and WCRS and compare results with relevant development consent conditions ormodelled EIS noise levels.1.2 Monitoring Locations and FrequencyTable 1.1 outlines the monitor type and frequency for the noise monitoring locations shownin Figure 1.Table 1.1 WAMBO COAL MONITORING LOCATIONS AND FREQUENCY1SiteReferenceSite LocationMonitorTypeConsent RequirementFrequency2N01 Lambkin Residence AttendedMine & Rail SpurDevelopment ConsentsQuarterlyN03Kelly ResidenceReal-time &AttendedMine Development ConsentContinuous & QuarterlyN16Muller ResidenceReal-time &AttendedMine Development ConsentContinuous & QuarterlyN20 Thelander Residence Real-time Mine Development Consent ContinuousN21Wambo SouthResidenceReal-time Mine Development Consent ContinuousN224 Henderson Residence AttendedRail Spur DevelopmentConsentQuarterlyN23 Redmanvale Road Attended Mine Development Consent QuarterlyN24 Curlewis Residence AttendedN25 Dyson Residence Rail Pass-byMine & Rail SpurDevelopment ConsentsRail Spur DevelopmentConsentQuarterlyEvery fifth quarterlyperiodNotes: 1.

1.4 Wambo Coal Mine Development ConsentWCM was granted consent (DA 305-7-2003) in February 2004, which enables the extension ofcurrent open cut and underground mining operations.The Wambo Coal Environmental Management System, Noise Monitoring Programme (DocumentEMP011, Rev 3, May 2007) was prepared in accordance with Schedule 4, Consent Condition 9.The Noise Monitoring Programme indicates that monitoring will be conducted for WCMactivities, and the noise levels to be used for assessment. Monitoring for noise from miningactivities is undertaken at the properties numbered N01, N03, N16, N23 and N24.It should be noted that properties N01, and N03 are within the Noise Affectation Zone for thedevelopment, and are also subject to acquisition upon request, as detailed in Schedule 4,Condition 1 of DA 305-7-2003. As such, there are no operational noise goals that applydirectly to these properties. Predicted maximum noise levels from the EIS are therefore usedfor comparison at these locations except where these levels are less than the minimumcriterion for intrusive noise nominated in the NSW Industrial Noise Policy (35 dB). In theseinstances, a criterion of 35 dB is used for assessment. Compliance with predicted levels atthese locations indicates likely compliance at properties further away from WCM.Table 1.3 summarises relevant noise assessment criteria for WCM.Table 1.3 WAMBO COAL MINE NOISE GOALSLocationL Aeq(15minute) Day dBL Aeq(15minute) Evening /Night dBL A1(1minute) Night dBN01 2 35 41 / 35 3 -N03 2 54 59 / 57 3 -N16 1 35 40 50N23 1 35 38 50N24 1 35 41 50Notes: 1.

1.5 Wambo Coal Rail Spur Development ConsentThe WCRS consists of two Development Applications (DA’s):The Wambo Rail Loop (DA 177-8-2004); and The Wambo Rail Line (DA 235/97).The Wambo Coal Environmental Management System, Noise Monitoring Programme (DocumentEMP011, Rev 3, May 2007) was prepared in accordance with Schedule 4, Consent Condition 9.The Noise Monitoring Programme indicates that monitoring will be conducted for WCRSactivities, and the noise levels to be used for assessment. Monitoring for noise from railactivities is undertaken at properties numbered N01, N22 and N24 each quarter and at N25every fifth quarter for rail pass-by noise.It should be noted that property number N22 is within the Noise Affectation Zone for thedevelopment, and is also subject to acquisition upon request, as detailed in Condition 1 of DA177-8-2004. As such, the operational noise goals or predictions do not apply directly to thisproperty. Monitoring was not undertaken at N22 after Quarter 3, 2010 due to a change ofownership.It is also noted however that Condition 2 of DA 177-8-2004 indicates that “While the land listedin Table 1 [of Condition 1] is privately owned, the Applicant shall implement all practicable measuresto ensure that the impacts of the development comply with the predictions in the SEE, and the relevantconditions in this consent, at any residence on this land, to the satisfaction of the Director-General.”Therefore, the predicted operational noise levels outlined in the Jerrys Plains Coal Terminal andRail Line Environmental Impact Statement and Statement of Environmental Effects (CMPS&F,1997), as reproduced in Resource Strategies (2005), are referred to in this report. Compliancewith the predicted levels from the EIS at this monitoring location indicates likely complianceat properties further away from the WCRS.Table 1.4 summarises relevant noise assessment criteria for the WCRS during operation.Table 1.4 OPERATIONAL NOISE GOALS, WAMBO COAL RAIL SPURLocationL Aeq Day dBL Aeq(15minute)Evening and Night dBL A1(1minute) Night dBN01 35 41 / 35 2 -N22 1 42 53 / 40 2 -N24 35 41 50Notes:1.

2 METHODOLOGY2.1 Assessment Method2.1.1 OverviewNoise monitoring was conducted at the nearest residences in accordance with the NSW Officeof Environment and Heritage (OEH) ‘Industrial Noise Policy’ (INP) guidelines andAustralian Standard AS 1055 ‘Acoustics, Description and Measurement of EnvironmentalNoise’. The mine was operating for all monitoring. WCRS monitoring was only conductedwhile train loading was in progress.Meteorological data was obtained from the Wambo Coal Mine meteorological station. Thisallowed correlation of atmospheric parameters and measured noise levels. Ground levelatmospheric condition measurement was also undertaken during attended monitoring.2.1.2 Attended Noise MonitoringAttended noise monitoring was conducted at all sites during day and night hours.Monitoring was not conducted in the evening period, as consent limits are the same forevening and night periods, and night time monitoring is considered a more suitable time tomeasure the source of interest. The duration of all measurements was 15 minutes.Attended monitoring is preferred to the use of loggers when determining compliance withprescribed limits; it allows an accurate determination of the contribution, if any, to measurednoise levels by the source of interest (in this case WCM and / or WCRS).Weather conditions were recorded at each location during each noise level measurement.Although the consent is not specific as to where the meteorological data should be sourced,information from WCM has been used as it is measured with an elevated anemometer as isrequired by the consent. The anemometer at WCM is not overly distant from the monitoringlocations and is considered to be representative of the general area. Wind speeds measuredat 10 metres above ground are usually higher than those measured closer to ground level. Inaccordance with consent conditions, noise criteria only apply in wind speeds up to 3 metresper second.2.1.3 Rail Pass-By MonitoringRail pass-by monitoring was conducted on the Wambo Coal Rail Spur at the Dyson propertyduring Quarter 2 2011. Sound exposure level (SEL) and L Amax were recorded for a total ofthree empty trains, and three loaded trains at this location.Three samples of each train configuration were gathered to ensure data was consistent(atypical data can be identified and excluded if required).

4 SUMMARY OF COMPLIANCE4.1 SummaryNoise levels from WCM complied with the development consent criteria or modelled noiselevels at all sites during the 2010/2011 attended monitoring, with the exception of N01 inQuarter 4 2010. At N01, an exhaust continuum was audible throughout the measurement,generating an L Aeq of 37 dB, an exceedance of 2 dB. A surge in the continuum generated anL A1,1min of 41 dB.This exceedance is not considered significant as Chapter 11 of the OEH ‘Industrial NoisePolicy’ deems a development to be in non-compliance only when “the monitored noise level ismore than 2 dB above the statutory noise limit specified in the consent or license condition.”Noise levels from WCRS complied with the development consent criteria or modelled noiselevels at all sites during the 2010/2011 attended monitoring.It is noted that wind speeds and/or temperature inversion conditions were at levels greaterthan which development consent conditions would apply for WCM and WCRS activities insome instances. In most instances, the predicted EIS noise levels were met regardless.Six train passes (three loaded, and three empty) were measured at the Dyson property duringQuarter 2, 2011. Rail pass-by L Amax and L Aeq,24 hour results at the Dyson property were lessthan relevant limits.Monitoring was delayed several times during Quarter 2, 2011 due to train scheduling and thearrival of trains coinciding with acceptable meteorological conditions. As a result of trying tofind a suitable time to undertake WCRS monitoring, the Quarter 2 2011 survey was extendedinto August 2011.11263_R01.docPage 26

Executive SummaryRPS Australia East (RPS) was commissioned by Wambo Coal Pty Limited (Wambo) toundertake the 2010 annual ecological monitoring program (monitoring program) for theirRemnant Woodland Enhancement Program (RWEP) in accordance with Wambo’sapproved Flora and Flora Management Plan, a consent condtion requirement for DA 305-7-2003, DA 177-8-2004 and EPBC 2003/1138 . The RWEP was established to offset landdisturbed by open cut coal mining. HLA-Envirosciences Pty Ltd initially established theannual flora and fauna monitoring program in 2006 (HLA 2007a, b). RPS commenced themonitoring program in 2007 (RPS Harper Somers O’Sullivan 2007), 2008 (RPS HarperSomers O’Sullivan 2009), 2009 (RPS 2010) and 2010 (this report).Flora monitoring identified 275 flora species across 34 flora quadrats. Currentmanagement practises within the RWEP areas of Wambo Coal Mine appear to beappropriate for the conservation of flora species. Variation evident in the results from thefive years of monitoring is most likely related to natural variation in species distribution,natural variation in species abundance and variation inherent in the sampling design, andnot to current management practises. There was no evidence to suggest that currentmanagement practices or mining activity was having any effect on the flora species withinthe RWEP areas of Wambo Coal Mine.While no Swift Parrots or Regent Honeyeaters were identified during targeted winter birdsurveys, annual surveys for these species should continue into the future, particularlyduring years of heavy eucalypt blossom when either or both species may occur onWambo Coal land.Diurnal bird monitoring identified 78 bird species across 26 survey sites, including seventhreatened species. Current management practises within the RWEP areas of WamboCoal Mine appear to be appropriate for the conservation of bird species. Variation evidentin the results across the years of monitoring is most likely related to natural variation inspecies diversity, natural variation in species abundance and variation inherent in thesampling design, and not to current management practises.No threatened owl species responded to call playback surveys. Due to the large homerange area of the target owl species and the relatively few (four) call playback sessionsundertaken each year, it is not unexpected that threatened owls species are rarelydetected.Spotlighting surveys identified the Common Brushtail Possum as the most commonarboreal mammal species in RWEP areas of Wambo Coal Mine. Across four years ofannual monitoring only three arboreal mammal species have been identified. TheCommon Brushtail Possum was identified each year and the threatened Yellow-belliedGlider and Squirrel Glider were recorded for the first time in 2010.There is no evidence to suggest that current management practices or mining activitiesare having any negative impact on fauna species.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page i

Riparian monitoring identified Stoney Creek as being in good condition, and North Wamboand South Wambo Creeks in moderate condition. Current bank erosion problem areas area result of historic land management practises however in the absence of currentmanagement will continue to degrade. Recommendations have been made to addressproblem erosion areas and to undertake other management actions that would lead toincreased condition scores for all three creeks.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page ii

1 IntroductionRPS Australia East (RPS) was commissioned by Wambo Coal Pty Ltd (Wambo) toundertake the annual ecological monitoring program for their Remnant WoodlandEnhancement Program (RWEP). The Remnant Woodland Enhancement Program wasestablished to offset land disturbed by open cut coal mining. HLA-Envirosciences Pty Ltdinitially established the annual flora and fauna monitoring program in 2006. RPS hasundertaken the monitoring program in 2007 (RPS Harper Somers O’Sullivan 2007), 2008(RPS Harper Somers O’Sullivan 2009), 2009 (RPS 2010) and 2010 (this report).The annual monitoring program comprises:• Flora Monitoring;• Fauna Monitoring, comprising;» Winter Swift Parrot and Regent Honeyeater surveys;» Diurnal bird surveys;» Owl call playback surveys;» Spotlighting surveys; and» Micro-bat surveys.• Riparian Condition Monitoring.1.1 Site LocationWambo is located within the Singleton Local Government Area and is approximately 15kilometres west of the township of Singleton. The open cut workings are located in thenorth of the site with a mixture of pasture-covered grazing land and native vegetationcomprising the remainder of the site. Figure 1-1 shows the regional location of the site.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 1

2 Flora2.1 MethodsIn 2010 at total of 34 permanent flora quadrats (20m x 20m) were surveyed (see Figure2-1), comprising 33 quadrats sampled in 2009 plus a new quadrat in 2010. The newquadrat was located within RWEP Area D bringing the total number of permanent floraquadrats in Area D to two. The new quadrat in Area D was added at the request ofLachlan Crawford of Wambo Coal Pty Ltd.The following parameters were collected in accordance with Table 8 of the Wambo CoalFlora and Fauna Management Plan:• Flora species diversity;» Total number of flora species;» Number and percent of native flora species; and» Number and percent of introduced flora species.• Flora species abundance (modified Braun-Blanquet 1-6 (Braun-Blanquet 1982)); and• Vegetation height of each vegetation layer in metres.Specimens of plant species which could not be identified within the field were collectedand identified according to nomenclature in Harden (1992, 1993, 2000 & 2002).Figure 2-1 shows the location of the 2010 flora plots.During the 2010 flora surveys, five flora plots (V1-A1, V1-A2, V1-B1, V1-B2 & V1-B3)were moved from within the channel of Wollombi Brook to the banks of the Brook as perthe recommendation in the 2009 report.2.1.1 Limitations of Flora SurveyNot all flora species occurring throughout the year are likely to be detected during asurvey undertaken once during the year. For example cryptic orchids flower within certainseasons and cannot be detected at other times of the year. Also, vegetation structure andcover abundance was estimated visually and as a result there are likely varied levels ofobserver bias.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 4

The three communities were:• River Oak / Rough-barked Apple Forest;• River Red Gum Woodland; and• Yellow Box / Blakely’s Red Gum / Rough-barked Apple Forest.» All other vegetation communities in 2010 recorded less than 25 percentintroduced species and most recorded less than 12 percent; and» The change in the percentage composition of introduced species in 2010 rangedfrom a reduction of 17 percent to an increase of 30 percent.• The percentage composition of introduced species within quadrats has ranged fromtwo (one species) to 68 percent (24 species) per quadrat across the five years ofsampling;• From 2007 to 2010 the change in the percentage composition of introduced specieswithin quadrats has ranged between a reduction of 14 percent and an increase of 19percent (see Appendix A [Table 4]);• The overall average change in the percentage composition of introduced species pervegetation community since 2006 has ranged from a decrease of seven percent to anincrease of 11 percent per vegetation community;• In 2007 most quadrats recorded an increase in the percentage composition ofintroduced species;• In 2008 all quadrats recorded minor changes in the percentage composition ofintroduced species, except quadrats within the River Oak / Rough-barked AppleForest community where four of the five quadrats recorded moderate to largedecreases;• In 2009 the change in the percentage composition of introduced species wasrelatively variable ranging from a decrease of 19 percent to an increase of 17 percent2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 7

however, most showed minor fluctuations;• In 2010 most quadrats recorded minor fluctuation in the percentage composition ofintroduced species;• Across the five years of sampling the average change in the percentage compositionof introduced species was:» Between minus eight and plus five percent per quadrat; and» Between minus three and plus one percent per vegetation community.• The River Oak / Rough-barked Apple Forest community recorded the most variableintroduced species composition over the five years.2.2.4 Introduced Species Abundance• Appendix C (Table 1) lists the introduced species recorded in 2010 and the numberof quadrats in which they were recorded;• A total of 47 introduced species were recorded in 2010;• The total number of introduced species recorded each year has ranged from 40 to 59species;• Senecio madagascariensis* (Fireweed) was the most frequently recorded introducedspecies in 2010, occurring in 27 quadrats;• Opuntia stricta var. stricta* (Prickly Pear) and Anagallis arvensis* (Scarlet Pimpernel)were recorded at 20 and 16 sites respectively in 2010;» Prickly Pear was observed at moderate densities in grassland areas in thewestern portion of RWEP area A. All individuals were less than half a metre inheight and were scattered (rather than occurring in dense stands);• All other introduced species in 2010 were recorded at less than eight sites and mostwere recorded at less than four sites;• Forty five introduced species recorded during the previous four years were notrecorded during 2010;• Fireweed, Prickly Pear and Scarlet Pimpernel were the most abundant introducedspecies during all years of sampling.2.2.5 Vegetation Heights• The 2010 vegetation height data (plus previous years) is shown in Appendix D;• Canopy height ranges recorded in 2010 were typically higher than those recorded in2009;• Most quadrats in 2010 recorded an increase in the height ranges of the first midstorey(the higher of two mid-storey layers when two are present);• Most quadrats in 2010 recorded the same height ranges for the second mid-storey(above the ground cover layer) as recorded in 2009;• Almost all quadrats in 2010 recorded the same lower strata (ground cover) heightranges as those recorded in 2009;2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 8

2.3 Discussion2.3.1 Species Diversity within Quadrats• Variation in the number of species recorded in 2010 between quadrats is a factor of:» Within vegetation communities;• Differences in quadrat conditions, such as minor differences in aspect, slope,and soil type;• Inherent differences in the species composition of a single vegetationcommunity throughout the community;• Variation in the amount of rainfall at each quadrat;» Between vegetation communities;• The different species composition of different vegetation communities,generally as a result of different site characteristics, such as slope, aspect,soil type, etc.• Variation in the number of species recorded across the five years of sampling is likelya factor of:» Seasonal conditions.• The increase in the number of species at all quadrats in 2007 is likely a resultof a good season;• The general decrease in the number of species at quadrats in 2008 is likely aresult of a poor season;• Moderate to minor fluctuations in the number of species recorded in quadratsin 2009 and 2010 are likely a result of moderate seasonal conditions.» The timing of surveys.• Cryptic species such as orchids have only a short flowering and detectableperiod. Surveys completed in different months or even weeks of the year arelikely to detect a different range of cryptic species.• There is no evidence to suggest that the number of flora species at any quadrat isbeing affected by current mining practises; and• Current land management practices within the RWEP areas appear to be appropriatefor the conservation of flora species diversity.2.3.2 Introduced Species Percentage Composition• Variation in the introduced species percentage composition is likely due to:» Vegetation community/quadrat landform location. The three vegetationcommunities that recorded more than 25 percent introduced species are alllocated within riparian locations where weed species are easily distributed bymoving water;» Variation in seasonal conditions from year to year;» Natural fluctuations in the abundance and distribution of introduced species from2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 9

year to year» The timing of surveys from year to year. Annual introduced species may bedetected in one month but not another;• There is no evidence to suggest that the fluctuations recorded in the percentagecomposition of introduced species is due to any factor other than a combination ofthose listed above.2.3.3 Introduced Species Abundance• Variation in the number of introduced species recorded in quadrats in 2010 is likely aresult of the same factors affecting the number of all flora species, as discussedabove in Section 2.3.1.• Fireweed.» The abundance of Fireweed has increased from six quadrats in 2006 to 27quadrats in 2010.» The increase is abundance is likely due to a favourable season in 2007 when thespecies was recorded in 21 quadrats followed by the natural spread of thespecies by airborne dispersal.» At most sites Fireweed was recorded at low density.» Due to the low density of Fireweed at sites where it occurs, the small size of theplant and the absence of a species specific control measure (i.e. a speciesspecific herbicide), no control actions are currently recommended for thisspecies.• Prickly Pear.» The abundance of Prickly Pear has remained approximately constant from 2006to 2010 being recorded in 17 and 23 quadrats.» At most quadrats Prickly Pear was recorded at low density.» The variation in the abundance of this weed species is likely due to naturalvariation in this species abundance, most likely as a result of the speciesinteraction with the Cactoblastis moth (Cactoblastis cactorum).» Although Prickly Pear occurs at moderate density in parts of RWEP area A(outside quadrats), no control measures are recommended as it is anticipatedthat the Cactoblastis moth will respond to the increased density through anincrease in its own numbers. It is expected that the density of Prickly Pear willdecrease over the next two years.• Scarlet Pimpernel.» Like Fireweed, the Scarlet Pimpernel increased in abundance in 2007, from 9 to15 quadrats and has since remained at approximately an equal level ofabundance.» At most sites Scarlet Pimpernel was recorded at low density.» Due to the low density of Scarlet Pimpernel at sites where it occurs, the smallsize of the plant and the absence of a species specific control measure (i.e. a2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 10

species specific herbicide), no control actions are currently recommended for thisspecies.• Spot herbicide spraying for African Boxthorn (Lycium ferocissimum) was undertakenduring 2010 along North Wambo Creek and has resulted in the death of almost allAfrican Boxthorn plants. Due to the low frequency of occurrence within flora quadrats(recorded in one quadrat in 2010) and the success of the 2010 spraying program, nofurther control measures are currently recommended.2.3.4 Vegetation Heights• Increases in the height ranges of the canopy and mid-storey one layers are likely aresult of:» Observer bias:• Several increases in height range were beyond a realistic amount of growthfor any of the species present;• Different observers recorded vegetation heights in 2009 and 2010;• Visual estimates, as opposed to measured values, are more prone tovariation and a lack of repeatability;• Measured values are not a feasible option as several measurements wouldbe required per vegetation strata and the resulting time requirement wouldlikely exceed the benefit of more accurate data; and• Observer bias is an inherent factor of annual surveys that generally is onlyavoidable in the short term.» Natural growth of species within each strata. However as mentioned above thedegree of growth is most likely a result of observer bias.2.4 RecommendationsThe following recommendations are suggested to maintain the quality and diversity offlora species within the RWEP areas of Wambo Coal:• Continue the exclusion of domestic stock from RWEP areas.• Continue the annual flora monitoring program in future years.• Undertake weed control measures where-ever weed species occur at high densities(not all areas were covered during the annual monitoring program).2.5 ConclusionCurrent management practises within the RWEP areas of Wambo Coal Mine appear to beappropriate for the conservation of flora species. Variation evident in the results from thefive years of monitoring is most likely related to natural variation in species distribution,natural variation in species abundance and variation inherent in the sampling design, andnot to current management practises. There was no evidence to suggest that current2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 11

management practices or mining subsidence was having any effect on the flora specieswithin the RWEP areas of Wambo Coal Mine.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 12

3 FaunaFive types of targeted surveys for fauna were conducted:• Swift Parrot and Regent Honeyeater winter surveys;• Diurnal bird surveys;• Nocturnal owl call playback surveys;• Spotlighting surveys; and• Anabat ‘micro-bat’ surveys.In addition to the above targeted surveys, opportunistic reptile and frog surveys were alsoundertaken during all other survey activities.3.1 MethodsFigure 3-1 shows the locations of the fauna survey points undertaken during 2010.3.1.1 Swift Parrot and Regent Honeyeater Winter SurveysSurveys for the Swift Parrot and Regent Honeyeater were undertaken on 21 June, 19 Julyand 17 August 2010. Each survey comprised a single day of survey by two ecologists fora total of 16 person hours of survey per day. Survey methodology comprised:• Searches for aggregations of nectivorous birds such as Noisy Friarbirds, whichindicate the presence of blossoming trees;• Searches for lorikeets and observation of their movements as an indication oflocalised occurrences of blossoming events; and• Opportunistic searches for threatened avian species.Surveys were undertaken throughout Remnant Woodland Enhancement Program(RWEP) areas A, B and C. All existing vehicle tracks were explored during searches forthe above possible indicators of suitable habitat areas for both target species.Opportunistic surveys were also undertaken while travelling throughout other areas ofWambo Coal Mine. During the surveys, special attention was given to identifying areascontaining flowering eucalypt trees.3.1.2 Bird SurveysA total of 26 bird surveys were undertaken in 2010 comprising the 24 bird survey locationsof the 2009 survey and two new bird survey locations in 2010 (established in Area D atthe request of Wambo Coal). Figure 3-1 shows the location of all 26 2010 bird surveylocations.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 13

Figure 3-1: Fauna Survey Effort2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 14

Bird survey locations are not marked in the field and were located with the use ofhandheld Global Positioning Systems (GPSs). At each location a one hectare area (100metres by 100 metres) was surveyed for bird species for a period of 20 minutes. At eachsurvey location the number of each bird species present was recorded. Species recordedoutside the one hectare area were also recorded (although numbers could rarely bedetermined from calls alone).3.1.3 Owl Call PlaybackOwl call playback surveys were conducted on four nights at four different locations(Figure 3-1) enabling calls to be broadcast over those portions of the three RWEP areasconsidered most likely to represent potential habitat for forest owl species. Forest owlsurveys were also conducted opportunistically during spotlighting surveys. The nocturnalcalls of the following species were played using a megaphone (10W rated output):• Barking Owl;• Masked Owl; and• Powerful Owl.The nocturnal calls of the Sooty Owl were also played at two call playback sites withinRWEP Area B where there was potential habitat for the species.After listening for five minutes, the calls of the above species were broadcast forapproximately four minutes each and were separated by a listening period of two minutes.At the end of each two minute listening period a brief spotlighting scan was made ofsurrounding trees for owls that approached silently. The calls were broadcast in the ordershown above. At the completion of the final species call, a listening period of five minuteswas undertaken and followed by a final spotlight scan of the surrounding trees.3.1.4 SpotlightingSpotlighting was undertaken across four nights by two people for a period of three hourseach night (six person hours per night). One and a half hours was undertaken on foot(predominately along vehicle tracks) and the remaining 1.5 hours was undertaken from aslow moving 4WD. See Figure 3-1 for the location of spotlighting transects.Where water bodies were encountered during spotlighting or where frog species could beheard calling in close proximity, frog searches were undertaken around the margins ofsuitable water bodies.3.1.5 Herpetofauna SurveysReptile species were recorded opportunistically during all ecological surveys throughoutthe day and frog surveys were undertaken when water bodies were encountered duringspotlighting.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 15

3.1.6 Bat SurveysNocturnal bat surveys were conducted at four sites over four nights within RWEP areas.Anabat detectors were used to record the echolocation calls of micro-bats. For each of thefour nights, two Anabat detectors were set for the entire night. Figure 3-1 shows thelocation of the Anabat detectors. All calls were analyzed by in-house staff with extensiveecholocation call identification experience.3.2 ResultsAppendix E lists all fauna species recorded during survey activities.3.2.1 Swift Parrot and Regent Honeyeater Winter SurveysNo Swift Parrots or Regent Honeyeaters were identified during winter bird surveys. Noareas of significant eucalypt blossom were identified. Limited eucalypt blossom wasrecorded on Eucalyptus crebra (Narrow-leaved Ironbark) and Eucalyptus tereticornis(Forest Red Gum) and both were frequented by Yellow-faced Honeyeaters(Lichenostomus chrysops).An additional seven threatened bird species were identified during the winter surveys.Appendix E lists all the bird species recorded during each survey and Figure 3-2 showsthe location of threatened species recorded during all surveys in 2010.3.2.2 Bird SurveysA total of 78 bird species were recorded from the 26 bird survey locations. The 2010 birdsurvey results are shown below as part of a comparison of data from the 2008, 2009 and2010 surveys. Unfortunately most of the 2007 bird survey data was not collated in aformat that allowed comparison with the more recent surveys.Total Species DiversityA comparison of the total number of bird species recorded across the four years identifiedthe following:• The total number of species has ranged between 66 and 86 species (2007 – 86, 2008– 66, 2009 – 84, & 2010 – 69);Species Diversity within SitesA comparison of the total number of bird species recorded at each site from 2008 to 2010(see Appendix F [Figure 1]) identified the following:• The number of species identified at any site has varied between two and 27 species;• In 2010 the change in the number of species from the previous year ranged between13 less species and 13 more species;• Two sites have shown an increasing number of species across the three years;• Eight sites have shown a decreasing number of species across the three years;• Fourteen sites have shown both increases and decreases in the number of species2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 16

ecorded across the four years;• The variation in the number of species recorded each year at each site is likely dueto:» Natural variability in the number of bird species at a site during any 20 minuteperiod;» Variability in seasonal conditions across the three years of sampling;» Variability in the time of year of surveys;» Variability in the time of day of surveys;» Observer bias. Likely variation in the skill level of observers across the four yearshas likely resulted in an unknown level of variability in the total number of speciesrecorded.• The variability in the number of bird species recorded at each site is likely due to acombination of the above factors and as such is essentially a result of variabilityinherent in the sampling design.Species Diversity across SitesA comparison of the number of sites at which each species was recorded in 2010 (seeAppendix F [Figure 2]) identified the following:• Nine species were recorded across ten or more sites in 2010. The nine species indecreasing order of the number of sites were the;» Rufous Whistler (Pachycephala rufiventris);» Weebill (Smicrornis brevirostris);» Superb Fairy-wren (Malurus cyaneus);» Yellow-faced Honeyeater (Lichenostomus chrysops);» Mistletoebird (Dicaeum hirundinaceum);» Speckled Warbler (Chthonicola sagittata) (Vulnerable – TSC Act);» Grey Fantail (Rhipidura albiscarpa);» Silvereye (Zosterops lateralis); and» Pied Currawong (Strepera graculina).• The Rufous Whistler was recorded at 21 of the 26 sites in 2010;• The Rufous Whistler was recorded across the highest number of sites in 2008, 2009& 2010.• The Rufous Whistler, Weebill and Yellow-faced Honeyeater are the most widelydistributed species at Wambo Coal, recorded in the top five of species in 2008, 2009& 2010.• Forty nine species were recorded across less than five sites.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 18

Species Abundance in 2010The number of individuals of each species was recorded for the first time in 2010. Acomparison of the number of individuals recorded across all sites (see Appendix F[Figure 3]) identified the following:• The Weebill was the most abundant species, with 91 individuals recorded;• Eleven species were recorded more than 20 times. The 11 species were the:» Weebill;» Rufous Whistler;» Superb Fairy Wren;» Yellow-faced Honeyeater;» Silvereye;» Speckled Warbler (Vulnerable – TSC Act);» Brown-headed Honeyeater (Melithreptus brevirostris);» Mistletoebird;» Buff-rumped Thornbill (Acanthiza reguloides);» Yellow Thornbill (Acanthiza nana); and» Grey Fantail.• Less than 10 individuals were recorded for 45 species;3.2.3 Owl Call PlaybackNone of the target owl species responded to the call playback of their calls and none ofthe four were detected during spotlighting surveys. Two non-threatened nocturnal birds,the Tawny Frogmouth (Podargus strigoides) and Australian Owlet Nightjar (Aegothelescristatus), were recorded during spotlighting surveys.3.2.4 SpotlightingAcross the four nights of spotlighting surveys, a total of 65 Common Brushtail Possums(Trichosurus vulpecula) were recorded. The 2010 spotlighting survey was the first toidentify more than a single arboreal species. In 2010 a single Squirrel Glider (Petaurusnorfolcensis) was recorded in RWEP Area B (see Figure 3-2). The Squirrel Glider is listedas ‘Vulnerable’ under the Threatened Species Conservation Act 1995 (TSC Act). Also in2010, a single group of Yellow-bellied Gliders (Petaurus australis) were heard callingduring spotlighting in RWEP Area B, and later replied to opportunistic call playback (seeFigure 3-2). The Yellow-bellied Glider is also listed as ‘Vulnerable’ under the TSC Act.3.2.5 Herpetological SurveysA total of 10 reptile species were recorded opportunistically during ecological surveys in2010 (See Appendix E). The Eastern Water Dragon (Physignathus lesuerii) wasfrequently recorded at the vehicle crossing of North Wambo Creek just above North2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 19

Wambo Creek’s junction with Wollombi Brook. All other reptile species were recordedrarely or only a single individual of each species was recorded.A total of 10 frog species were recorded during searches of water bodies as part ofspotlighting surveys. Five species were commonly recorded, namely the, Spotted MarshFrog (Limnodynastes tasmaniensis), Smooth Toadlet (Uperoliea laevigata), Dwarf GreenTree Frog (Litoria fallax), Broad-palmed Frog (Litoria latopalmata) and Peron’s Tree Frog(L. peronii). The Ornate Burrowing Frog (Limnodynastes ornatus) was recorded severaltimes foraging along vehicle tracks. The remaining species were recorded on an occasionbasis across the searched water bodies.3.3 Discussion3.3.1 Swift Parrot and Regent Honeyeater Winter SurveysTargeted winter bird surveys for the Swift Parrot and Regent Honeyeater during 2008,2009 and 2010 have failed to identify either species. Each year a limited foraging resourceof few eucalypt blossoms was also identified and reduced the chances of recording eitherspecies. Due to each species highly nomadic movement patterns, the failure to recordeither species does not suggest that they do not occur at Wambo Coal. When years ofheavy eucalypt blossom do occur, either species may occur in response to the presenceof an increased foraging resource.3.3.2 Bird SurveysTotal Species DiversityThe variation in the number of species recorded each year is likely due to:• Variability in seasonal conditions across the four years of sampling;• Variation in the number of sites sampled each year (ranged from 22 to 26);• Variability in the time of year of surveys; and• Observer bias. Likely variation in the skill level of observers across the four years haslikely resulted in an unknown level of variability in the total number of speciesrecorded.The variability in the total number of bird species recorded is likely due to a combination ofthe above factors and as such is a result of natural variation and inherent samplingvariation.Species Diversity within SitesThe variation in the number of species recorded each year at each site is likely due to:• Natural variability in the number of bird species at a site during any 20 minute period;• Variability in seasonal conditions across the three years of sampling;• Variability in the time of year of surveys;• Variability in the time of day of surveys;2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 20

• Observer bias. Likely variation in the skill level of observers across the four years haslikely resulted in an unknown level of variability in the total number of speciesrecorded.The variability in the number of bird species recorded at each site is likely due to acombination of the above factors and as such is essentially a result of variability inherentin undertaking a single brief survey at each site.Species Diversity across SitesThe variation in the number of sites at which each species was recorded is likely due to:• Variation in the habitat preferences of each species;• Variation in the density of each species;• Variation in the detect-ability of each species.The variability in the number of bird species recorded at each site is likely due to acombination of the above factors and as such is essentially a result of the naturalvariability in the distribution of species across the sample sites. As such the RufousWhistler, Weebill and Yellow-faced Honeyeater are the most widely distributed speciesacross the sites sampled.Species Abundance in 2010The variation in the number of individuals across all sites is likely due to:• Variation in the habitat preferences of each species;• Variation in the natural density of each species;• The population structures of individual species. Some species move around in flocks,others in pair and others singularly. Additionally some species are resident and aremore likely to be recorded than migratory species.• Variation in the detect-ability of each species.The variability in the number of bird species recorded at each site is likely due to acombination of the above factors and as such is essentially a result of the naturalvariability in the distribution of species across the sample sites.3.3.3 Owl Call PlaybackNo threatened owl species were recorded during the 2007 and 2010 annual surveys. ThePowerful Owl was recorded once in 2008 and the Masked Owl was recorded once in2009. Due to the large home range area of the target owl species and the relatively few(four) call playback sessions undertaken each year, it is not unexpected that threatenedowls species are rarely detected. The variation in the results of owl call playback sessionsacross the years appears to be a result of the combination of the sampling methodologydesign and the natural distribution and abundance patterns of the target species.The Tawny Frogmouth and Australian Owlet Nightjar were recorded during spotlightingsurveys in all four years. Both species were recorded in low numbers and appear to bepresent at a relatively low density.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 21

3.3.4 SpotlightingThe Common Brushtail Possum is a commonly occurring nocturnal arboreal species atWambo Coal, evidenced by the recording of 65 individuals during the 2010 surveys. Theidentification of the Squirrel Glider and Yellow-bellied Glider, for the first time in 2010, arelikely a result of the inclusion of spotlighting surveys within in the southern parts of RWEPArea B in 2010 (see Figure 3-1).3.3.5 Herpetological SurveysTable 3-1 shows the number of reptile and amphibian species recorded over the fouryears of monitoring.Table 3-1: Number of reptile and frog species recorded over the four years of monitoringYear No. of Reptile Species No. of Frog Species2007 8 122008 8 92009 5 62010 10 10The level of variation in the number of reptile and frog species recorded during the fouryears of sampling is most likely a result of variation in seasonal conditions across theyears. Additionally variable weather conditions and dates of survey (months of year) arelikely to have caused variation in the number of species recorded.3.4 ConclusionWhile no Swift Parrots or Regent Honeyeaters have been identified during targeted winterbird surveys, annual surveys for these species should continue into the future, particularlyduring years of heavy eucalypt blossom when either or both species may occur onWambo Coal land.Current management practises within the RWEP areas of Wambo Coal Mine appear to beappropriate for the conservation of bird species. Variation evident in the results from threeto four years monitoring is most likely related to natural variation in species diversity,natural variation in species abundance and variation inherent in the sampling design, andnot to current management practises.Due to the large home range area of the target owl species and the relatively few (four)call playback sessions undertaken each year, it is not unexpected that threatened owlsspecies are rarely detected.Spotlighting surveys identified the Common Brushtail Possum as the most commonarboreal mammal species in RWEP areas of Wambo Coal Mine. Across four years ofannual monitoring only three arboreal mammal species have been identified. The2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 22

Common Brushtail Possum was identified each year and the Yellow-bellied Glider andSquirrel Glider were recorded for the first time in 2010.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 23

4 Riparian Monitoring4.1 MethodsRiparian assessments were undertaken by repeating methods defined by HLA (2007)which included taking pedestrian based surveys along sections of North Wambo Creek,South Wambo Creek and Stoney Creek utilising field sheets to give an overall rating ofcreek health.Pedestrian based surveys were undertaken from 7 to 9 September 2010. Two types oftransect were assessed for each of the three streams, these were:• Cross sectional – A marked single line transect across the width of the stream frombank to bank, hereafter referred to as ‘transects’; and• Longitudinal – An unmarked transect along the length of the creek between twotransects, hereafter referred to as ‘sections’.Transect and section locations were established in the field by HLA (2007) and comprisethe length of underground workings, plus at least one site beyond each end of theunderground workings. During 2010 all transect locations were remarked with labelled starpickets. Previously transect start and finish locations were marked with a wooden stakeand a surveyors marker peg however, during 2010 almost all wooden stakes had fallenover or had disappeared, and all surveyors pegs were hidden in long grass.Two types of riparian monitoring were undertaken – bed and bank stability monitoring, andriparian vegetation monitoring.Bed and Bank stabilityBed and bank stability monitoring is undertaken by surveying consultants who undertakereplicate surveys of the three creeks to measure areas of significant erosion and toidentify changes related to water flow. A written assessment was completed of any areasof significant erosion, bare soil and visible subsidence along each creek line.Riparian Vegetation MonitoringThe effects of subsidence and erosion on riparian vegetation were monitored by repetitivesampling of established permanent transects by assessing:• The current erosion status of transects and sections;• Photographing each transect site and any areas of significant erosion or subsidenceimpacts; and• Quantifying vegetative structure and species composition for each transect by:» Completing visual assessment field sheets (see Appendix G) of weightedriparian vegetation characteristics to give an overall rating. Riparian vegetationcomponents assessed included:• Overstorey characteristics;2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 24

• Understorey characteristics;• Ground cover characteristics;• Introduced species presence;• Feral animal activity;• Surface Stability;• Riparian microhabitat presence; and• Disturbance levels.» Visual assessment field sheets were updated in 2010 to remove inconsistenciesin the weighting of scores. Negative attributes were given negative scores in2010.» Due to the change in the weighting of scores in 2010, comparison between 2010results and previous results cannot be made.Field Sheet Scoring SystemTransects and sections are awarded different colours according to their total scorecondition rating. Sites ranked as poor are colour coded red, moderate as yellow, good asgreen, and excellent as blue. The maximum possible score is 54 and the minimumpossible score is -51. Total score categories are as follows:• Greater than 33 – Excellent condition (blue);• 28 to 33 – Good condition (green);• 14 to 27 – Moderate condition (yellow);• Less than 14 – Poor condition (red).The above condition rating score ranges are not equally weighted and were determinedby an assessment of the maximum possible score for each assessed component at eachcondition level.Poor condition sites are likely highly degraded and/or missing significant vegetationstructural components. Active management would likely be required to improve the scoresof poor condition sites. Moderate condition sites are considered relatively satisfactory andrequire varying degrees of land management (to be considered on a site by site basis).Good condition sites are considered in relatively good health and may only requiremaintenance works such as weed control. Excellent condition sites are consideredunlikely to require any maintenance.4.2 ResultsFigures 4-1 and 4-2 show the results of the riparian condition assessments along SouthWambo Creek, North Wambo Creek and Stoney Creek. Appendix H lists the individualtransect and section scores for each creek line. Appendix I shows the 2010 photographsof each transect site.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 25

4.2.1 South Wambo CreekTransectsSouth Wambo Creek was dominated by moderate transect and section condition scores.The five transects along South Wambo Creek were in poor (two transects) and moderate(three transects) condition. South Wambo Creek condition scores were typically poor dueto:• The absence of an understorey layer;• A species poor and immature canopy layer with little recruitment;• A species poor ground cover layer with increasing areas of bare soil and decreasingareas of foliage cover;• The presence of rabbits;• The presence of minor stream bank erosion and minor sedimentation evidence; and• The absence of some riparian microhabitat features.SectionsThree sections along South Wambo Creek were found to be in moderate condition. Thefourth section was in good condition. South Wambo Creek condition scores were typicallycharacterised by:• A moderately species diverse canopy layer;• A low and sparse understorey layer containing some weed species;• A relatively species poor ground cover layer with increasing areas of bare soil anddecreasing areas of foliage cover;• A high diversity of weeds;• The presence of rabbits;• The presence of some riparian microhabitat features; and• A lack of other disturbance factors.4.2.2 North Wambo CreekTransectsNorth Wambo Creek was dominated by moderate transect and section condition scores.Thirteen of the 15 transects along North Wambo Creek were found to be in moderatecondition. One transect was in good condition while the remaining transect was in poorcondition with a score of only five. North Wambo Creek transect condition scores weretypically characterised by:• A mature but species poor canopy of moderate density;• A sparse and short ground cover layer;2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 28

Sections• A relatively high number of weed species;• Some areas of gully and stream erosion;• The presence of rabbits at some sites; and• The presence of some riparian microhabitat features.North Wambo Creek Transect 4 was in poor condition scoring only five. Transect 4 lackedboth canopy and understorey layers and was essentially a grassland containing manyweed species. However, while scoring only five, Transect 4 had one hundred percentground cover and lacked any areas of erosion and most disturbance factors (rabbits werepresent).The majority of sections along North Wambo Creek were in moderate condition. Threesections were in good condition and one was in excellent condition. North Wambo Creektransect moderate condition scores were typically characterised by:• A mature canopy of moderate species diversity and density;• Some weed species in the understorey;• A complete ground cover of grasses, although containing some weed species;• The presence of rabbits at some sites;• Some areas of gully and stream erosion; and• The presence of some riparian microhabitat features.In comparison to the moderate condition sites the good and excellent sections along NorthWambo Creek typically showed:• An reduced presence of weed species in the canopy, understorey and ground coverlayers; and• A higher presence of riparian microhabitat features.4.2.3 Stoney CreekTransectsSectionsStoney Creek comprised excellent transect and section scores where sites were withinremnant forest vegetation, and good and moderate scores for sites adjacent to or lackingremnant forest vegetation.Stoney Creek transect scores ranged from excellent in the upper reaches of the creek lineto good and moderate along the lower more disturbed parts of the creek line. Thepresence of a more significant canopy layer, a general lack of weed species and theabsence of feral animals were the key differences between the excellent scoring transectsand all others along Stoney Creek. While the condition score varied, all transects alongStoney Creek lacked areas of erosion.Stoney Creek sections scores also ranged from excellent in the upper reaches of thecreek line to good and moderate along the lower more disturbed parts of the creek line.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 29

Excellent scores resulted from an increased number of ground cover species, thepresence of a litter layer and an absence of feral animal species. Three of the foursections along Stoney Creek recorded minor levels of erosion.4.2.4 Overall Riparian ConditionAveraging the value of transect and section scores for each creek identified Stoney Creekin good condition and both North Wambo Creek and South Wambo Creek in moderatecondition.4.2.5 Annual Riparian Condition PhotographsIn 2010 four photographs were taken at each riparian transect, with individualphotographs showing the left bank, right bank, upstream channel and downstreamchannel. Appendix I shows the photographs from the 2010 riparian conditionassessment. Riparian condition photographs during previous years were varied in theirlocation, typically showing areas of problem erosion.4.3 DiscussionBoth South Wambo and North Wambo creeks are historically deeply eroded creek lines,up to four to five metres deep in some parts. Stoney Creek is a shallow narrow creek inthe upper sections and a wide and historically deeply eroded creek in the lower parts.Past land management practices (presumably land clearing during European settlement)have resulted in all three creeks being present as deeply eroded channels. Today all threeare essentially grass covered channels with scattered or remnant tree cover and someareas of minor or moderate erosion.All three creeks contain some scattered areas of active erosion typically present aseroding or collapsing banks. These areas of erosion and collapsing banks do not appearto be a result of current land management practices however there is little evidence ofcurrent land management practices to reduce or eliminate the erosion that is occurring.Where possible, remedial works to repair eroded banks or tree planting to help stabilisebanks, should be undertaken.Two common causes for reductions in condition scores were the presence of weeds andthe presence of rabbits. Selective spraying of African Boxthorn had been undertakenduring 2010 however a large percentage of the ground cover vegetation is composed ofintroduced exotic species. While these species appear to be outcompeting native groundcover species, they provide protection for the soil from erosion and should only beremoved when successional native species are planted and have become established.Management to control the number and presence of rabbits along the creeks wouldincrease the stability of banks and result in increased condition scores.No impacts from mining subsidence were found along any of the three creeks.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 30

4.4 RecommendationsImplementation of the following recommendations would improve the condition scores ofNorth Wambo Creek, South Wambo Creek and Stoney Creek:• Where appropriate, undertake remediation works at sites of significant bank erosion;• Where remediation works are likely to cause more damage than good, plantseedlings of local tree species around erosion areas to stabilise banks and assist inthe prevention of future erosion;• Prevent or limit livestock access to North Wambo Creek and Stoney Creek;• Undertaken rabbit control measures along all three creeks;• Undertake a weed management program that uses successional techniques that donot leave areas of bare soil;4.5 ConclusionRiparian monitoring identified Stoney Creek as being in good condition, and North Wamboand South Wambo Creeks in moderate condition. Current bank erosion problem areas area result of historic land management practises however in the absence of currentmanagement will continue to degrade. Recommendations have been made to addressproblem erosion areas and to undertake other management actions that would lead toincreased condition scores for all three creeks.2010 Annual Ecological Monitoring Report, Draft Report, January 2011 Page 31

Safety clip refitted to the fuel nozzlefitting and checked for further leaks.In accordance with Wambo Coal’s statutory obligations,the DECCW was informed. A detailed investigation andreport was completed and sent to the DECCW on 24February 2010.Analysis of the blast footage has shown that the shotwas well contained by the stemming and the faceburden. Analysis of the wave trace from the Mullermonitor, in combination with overpressure modelingsuggest that the orientation of the pattern in combinationwith the surface delay (inter-hole) timings is likely to bethe main contributor to the overpressure reading. Thepeak pressure occurred right at the start of the trace,with the positive phase of the peak overpressurerecorded at 124.4dB at the Muller Blast Monitor.Preventative actions include: The use of slower timings when firing on thisorientation (42ms instead of 17ms). The use of new air overpressure modeling tools toanalyse the reinforcement patterns when designingthe pattern tie in. Smaller blasts, so that there are fewer holesavailable to reinforce the pressure front, whilst alsoreducing the stochastic nature of the system byminimising the timing scatter; and Continued monitoring of weather parameters at thetime of firing and delay of shots until morefavourable conditions prevail.13 8/03/2011 Downer EDI / OpenCut2 Blast event resulted in large Nox plumewhich blew in a NNW direction.
