Noise<br />
Question ñ How noisy are the <strong>LNG</strong> trains?<br />
Until the <strong>LNG</strong> <strong>Precinct</strong> layout has been developed and the design work completed, it is<br />
not possible to give absolute noise levels. However, the average noise level at the<br />
<strong>Precinct</strong> boundary is targeted to be 65 decibels. A noise level <strong>of</strong> 65 decibels is roughly<br />
equivalent to slightly elevated speech or laughter.<br />
Noise management in Western Australia is implemented through the Environmental<br />
Protection (Noise) Regulations 1997 under the Environmental Protection Act 1986. The<br />
plant will be designed to meet the requirements <strong>of</strong> the relevant legislation. Further<br />
information can be obtained from the Environmental Protection Authorityís Guidance for<br />
the Assessment <strong>of</strong> Environmental Factors Statement 8 - Environmental Noise. In<br />
addition; the noise sources on the plant will need to meet occupational noise standards.<br />
Drainage and Watercourse Management<br />
Questions:<br />
� If there are any rivers and creeks in the <strong>Precinct</strong>, how will you manage them?<br />
� How will drainage issues be handled?<br />
There are two main creeks in the James Price Point area (one to the north and one south<br />
<strong>of</strong> James Price Point). In addition, there are a number <strong>of</strong> minor creeks. The aim is to<br />
avoid the two larger creeks to minimise potential environmental impacts and also<br />
because the volume <strong>of</strong> water is likely to be too large to manage. No hydrology (surface<br />
water run<strong>of</strong>f) studies have been carried out to date although we now have the area <strong>of</strong> the<br />
catchments for all creeks. A hydrology study will be completed as part <strong>of</strong> the Strategic<br />
Assessment.<br />
Site earthworks will create a series <strong>of</strong> level terraces. There will be no impact or access<br />
restriction on the two major creeks from these earthworks. There may be some impact<br />
on the minor creeks, however this will only be possible to assess once the site has been<br />
defined and the hydrology study is completed. On comparable projects where waterflows<br />
have been large, creeks have been maintained and bridges built at crossing points<br />
within the plant site. If required, this approach could possibly be adopted for the James<br />
Price Point site.<br />
Where pipelines need to cross creeks they will be buried under the ground and the creek<br />
area rehabilitated so natural flows are not changed.<br />
