Existing Metropolitan Colliery Noise<br />
During daytime with Colliery Road coal haulage (ie trucks operating) the existing Metropolitan<br />
Colliery noise levels at the nearest receivers are up to 12 dBA (O14, O16) above the criteria. In<br />
the absence of coal haulage (ie trucks not operating) the existing noise levels are up to 9 dBA (O2<br />
and O4) above the criteria.<br />
Predicted Project Noise<br />
Following the implementation of potential noise controls (Section 7) the Project Year 3 and 15<br />
noise levels are predicted to reduce at all assessed receivers to the west and south of the site.<br />
Project noise levels at receivers near the Project boundary to the north are generally predicted to<br />
remain unchanged due to the inclusion of train loading activities in the model, which are in close<br />
proximity and dominate noise emissions at these locations.<br />
8.2 Evening Existing Metropolitan Colliery and Project Year 3 and 15<br />
The predicted evening 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, support<br />
mobile equipment, and train loading are presented in Table 20. No coal or coal reject road<br />
haulage is to be undertaken in the evening.<br />
