• Use of modern low-noise front-end loader and 30 t off-road trucks for on-site coal reject haulage (between the CHPP and the temporary coal reject stockpile or paste backfill plant). Specific operational noise control measures incorporated in the noise model to meet specified SWL emissions and/or modelled levels at the nearest private receptors include: • Project surface construction activities to be restricted to daytime hours. • No off-site road haulage of product coal or coal reject during the evening or night-time periods (continuation of an existing Metropolitan Colliery operational noise control measure). • No haulage of coal reject between the CHPP and the temporary stockpile or between the CHPP and the backfill paste plant to be undertaken in the evening and night-time periods. • Use of broadband noise alarms on existing and future equipment adjusted to meet occupational health and safety (OHS) requirements. The above measures would be implemented progressively eg conveyor upgrade and mitigation would not occur until after Year 3 (refer Initial Development Schedule). For the purposes of noise impact assessment, the design maximum LAeq SWLs are presented in Table 18 for the all acoustically-relevant items of plant and equipment for the Project (once upgraded).

7.6 Continuous Noise Improvement Programme In addition to the noise controls described in Sections 7.4 and 7.5, HCPL would commit to implement a Project continuous noise improvement programme in accordance with the requirements of the EPL, involving an Acoustical Design, Procurement, Construction and Commissioning process for the Project, including: • Noise limits and acoustical specifications • Best Available Technology for each Stage of development. • Environmental and OHS acoustical specifications for all equipment types. • Desktop design validation and supplier shop testing • Equipment suppliers must demonstrate acoustical conformance during tender phase. • Environmental and OHS acoustical shop testing during procurement phase. • In-situ acceptance testing • Environmental and OHS acoustical field testing during plant commissioning. • Refitting and or replacement in the event of non-compliance. • Computer-based acoustical modelling • Acoustical modelling of installed plant using actual achieved SWLs. • Preparation of detailed acoustical compliance report for each Stage of development. • Noise emission monitoring and reporting • On-site and off-site operator-attended noise surveillance measurements of acoustically significant plant. • In the event of community concerns • Prompt response and targeted noise monitoring where required. • Refinement of on-site noise operating procedures where practicable. 8 INTRUSIVE NOISE IMPACT ASSESSMENT The Metropolitan Colliery is a significant existing facility in close proximity to a range of residential receptors and other suburban landuses. The Project upgrades to the major surface facilities area would not significantly change the location, nature or the main characteristics of the Metropolitan Colliery on-site noise emissions. Therefore, for comparative purposes, modelled intrusive noise predictions for the Project (Year 3 and Year 15) have been compared to modelled intrusive noise emissions for the existing Metropolitan Colliery in the subsections below for the daytime, evening and night-time periods with the application of significant weather conditions in accordance with the INP. 8.1 Daytime Existing Metropolitan Colliery and Project Year 3 and 15 The predicted daytime intrusive noise from the existing Metropolitan Colliery and proposed Project Year 3 and Year 15 operations from all on-site activities including all fixed plant and support mobile equipment and train loading are presented in Table 19. Table 19 incorporates examination of the contribution of on-site road haulage of coal or coal reject on Colliery Road to noise levels at receptors (ie model predictions have been generated with and without this equipment operating).
