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 />
