CONSTRUCTION ENVIRONMENTAL MANAGEMENT PLAN

Construction Environmental Management PlanIncorporation of a drainage system along the rail infrastructure corridor to maximise rainfall runoff andminimise infiltration. The drainage system includes table drains along the length of the corridor to collectand divert runoff to the existing site drainage system via sediment control structures. The rail embankmentincludes culverts where it traverses low points in the existing topography to allow drainage across itsalignment.An infiltration drainage layer with an effective permeability not less than 1x10 -5 m/s and a revegetation layerwill be placed across the capping layer as part of Project closure and rehabilitation works.The capping layer and drainage layout will be designed such that they can be readily integrated with theHDCs ultimate capping strategy for the whole KIWEF.The capping and drainage works undertaken during Stages 1 and 2AA of the Project were completed to thenecessary standard, and the works were verified by an independent auditor in accordance with Condition 2.53,Schedule 2 of the Project Approval (06_0009).The capping and drainage works undertaken during Stage 2F will be completed to the necessary standard, andthe works verified by an independent auditor in accordance with Condition 2.53, Schedule 2 of the ProjectApproval (06_0009).The design and construction of the NCIG CET rail infrastructure will be undertaken in accordance with therequirements of the Australian Rail Track Corporation (ARTC) who manage the Hunter Valley Coal Rail Network.Grade SeparationThe grade separation for the inbound track to the NCIG Northern Rail Spur will require earthworks and civil workswithin the approved corridor width and general alignment for the NCIG Northern Rail Spur, and include a bridgestructure to allow for the realigned and lowered outbound (eastern) track of the Kooragang Island Main Line topass beneath. Allowance for additional tracks for the proposed Terminal 4 Project will be made in the overallbridge length (i.e. span) design (Aurecon Hatch, 2011).The Rail Flyover Modification does not change the approved corridor width or general alignment of the NCIGNorthern Rail Spur.Kooragang Island Main Line RealignmentsA 790 m section of the Kooragang Island Main Line inbound track will be removed and undergo minorrealignment to the west to allow for ramping of the track to the NCIG Northern Rail Spur bridge structure. Therealignment will require earthworks and civil works.A 1,100 m section of the Kooragang Island Main Line outbound track will be realigned to pass beneath the NCIGNorthern Rail Spur bridge structure. The realignment will require earthworks and civil works, including loweringof the outbound track beneath the NCIG Northern Rail Spur bridge structure. The outbound track passing underthe grade separated northern rail spur will have a clearance of 4.8 m, to enable the safe clearance of outgoingtrains leaving Kooragang Island (including the Port Waratah Coal Services Kooragang Coal Terminal).The realigned section of the Kooragang Island Main Line outbound track will traverse the existing KIWEF. Therealignment of the outbound track (including the associated embankment) has been specifically designed toavoid Deep Pond beyond that for the approved NCIG CET.The Kooragang Island Main Line inbound and outbound track realignments are shown on Figure 2.Approximately 360,000 tonnes (t) of clean fill material will be required to construct the rail flyover and associatedrail realignments. Clean engineering fill material will be sourced from nearby quarries located in the Lochinvararea and transported by truck to the NCIG CET.Other Associated Ancillary InfrastructureExisting power poles, wiring, lighting and signalling equipment and other minor infrastructure associated withrealigned sections of the Kooragang Island Main Line, will be relocated and installed within the proposed railrealignment corridors or re-connected to existing/realigned linear infrastructure components (e.g. adjacentAusgrid powerlines).7
