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