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 />
