The DECC currently adopts the Australia and New Zealand Environment Council Committee (ANZECC) “Technical Basis for Guidelines to Minimise Annoyance due to Blasting Overpressure and Ground Vibration” dated September 1990 for assessing potential annoyance from blast emissions during daytime hours. The assessment of blast emission impacts outside the hours advocated by ANZECC remains according to the “Environmental Noise Control Manual” (ENCM) (EPA, 1994) Chapter 154 Noise Control Guideline - Blasting. Off-site Transport Noise Road Traffic: The existing site access and coal haulage routes remain unaltered by the Project and mine generated employee and materials movement along these public roads are not increased significantly by the Project operation. Slight traffic increases are anticipated to occur during Project construction and operation and are therefore assessed in accordance with the DoP’s requirements. The NSW “Environmental Criteria for Road Traffic Noise” (ECRTN 1999) provides non-mandatory procedures for setting acceptable LAeq noise levels on arterial, collector and local roads and guidelines for assessing noise impacts from off-site road traffic. Rail Traffic: The Rail Corporation NSW (RailCorp) operates the South Coast rail network in NSW. Noise emissions from the railway are regulated via RailCorp’s Environment Protection Licence (EPL No 12208, review date 17 December 2012). 1.2 Current Approvals The Metropolitan Colliery is regulated via the DECC EPL Licence No 767 (review date 9 September 2009) and associated Pollution Reduction Program (PRP) requirements. The current EPL includes PRP 12 - Stage 2 Noise Investigation and Mitigation Program (Attached as Appendix A1). While the EPL does not nominate specific regulatory noise limits, PRP 12 nominates provisional noise criteria (noise goals) as presented in Table 1. Measured background noise levels in the absence of the Metropolitan Colliery operations are further discussed in Section 4 and project specific noise assessment criteria are presented in Table 14.

PRP 12 Study major findings include: • The Metropolitan Colliery’s existing noise emissions are well above the DECC’s PRP 12 noise goals and it is not reasonable and feasible to achieve the nominated goals in the absence of some major change such as complete replacement and relocation of the CHPP building and associated materials handling plant and equipment. • HCPL conduct a Washery Building Noise Control Engineering Feasibility Assessment and implement noise controls as identified by the assessment. HCPL investigate coal reject and product truck subcontract dates and options for variations with respect to noise emissions.

• HCPL to implement a continuous noise improvement program for the major surface facilities area including a low noise maintenance replacement and procurement policy. • HCPL to consult with DECC in relation to setting revised noise goals for the on-going operation of the Metropolitan Colliery and reasonable and feasible noise reduction targets. • HCPL revisit the above program at any time, subject to the progress and outcomes of the proposed Project. The PRP 12 Study report was prepared independently of HCPL’s plans for the Project, however as anticipated, it is now appropriate to draw upon the PRP 12 Study major findings, which have been incorporated into this Project noise impact assessment where consistent with the EARs and the NSW INP guidelines. 2 PROJECT OVERVIEW 2.1 Overview of Project Operations The Project general arrangement and an indication of the progressive development of the Project longwalls over the life of the Project are shown in Appendix B1. The general arrangement of the Project has been designed to maximise the utilisation of existing Metropolitan Colliery infrastructure. The major surface facilities to be upgraded or added are shown in Appendix B2. The main activities associated with development of the Project would include: • Ongoing surface and underground exploration activities in the Project underground mining area and surrounds. • Continued development of underground mining operations within existing HCPL mining and coal leases (and associated sub-leases) and two new Mining Lease Application areas (MLA 1 and MLA 2). • Upgrade of the existing mining and materials handling systems (eg longwall machinery and conveyors) to facilitate an increased run-of-mine (ROM) coal production rate (up to approximately 3.2 million tonnes per annum [Mtpa]). • Upgrade of the CHPP to facilitate increased production of washed coal (approximately 2.8 Mtpa), including the addition of a beneficiation circuit to produce a new thermal coal product. • Continued transport of coal reject to the Glenlee Washery for emplacement by Sada, with annual road movements capped at the existing maximum rate. • Continued transport of product coal by road to Coalcliff and Corrimal coking plants, with annual road movements capped at the existing maximum rate. • Construction of a coal reject paste backfill plant and associated coal reject stockpile, pumping, pipeline and underground delivery systems to facilitate the underground emplacement of coal reject materials as an integrated component of the longwall mining operation. • Train loading and train movements associated with the transport of product coal to Port Kembla 24 hours per day and seven days per week. • Surface access within the Woronora Special Area and surrounds that is required for the environmental monitoring, management and remediation of mine subsidence. • Upgrade and/or extension of the existing supporting infrastructure systems (eg underground access, water management, ventilation and electrical systems) as required. • Other associated minor infrastructure, plant, equipment and activities. The Project would extend the life of the Metropolitan Colliery by approximately 25 years.
