ATTACHMENT E - REVISED NOISE AND DUST MANAGMENT PLAN<br />

ITEM 11.1 COUNCIL 24/04/2013<br />

Sand Extraction – Lot 75, Haag Road, Yelverton<br />

4 NOISE<br />

4.1 POTENTIAL IMPACTS AND NOISE SOURCES<br />

Operating machinery will be the main source <strong>of</strong> noise from the Project, both earthmoving equipment and<br />

haulage trucks. Earthmoving equipment is restricted to site, whilst trucks will traverse private property<br />

and local roads to the highway.<br />

Noise emission will occur during operation between the hours <strong>of</strong> 7am to 6pm Monday to Friday,<br />

excluding public holidays and school bus hours. No extraction work will take place outside these hours.<br />

Trucks will generally operate on Monday to Friday between the hours <strong>of</strong> 7.30am and 8.40am and<br />

between 3.20pm and 4.20pm.<br />

A number <strong>of</strong> important variables need to be considered when assessing the risk <strong>of</strong> noise generation and<br />

assigning or developing management strategies to minimise noise. Table 4-1 below outlines those<br />

variables pertinent to the Project.<br />

Table 4-1 Variables Influencing the Risk <strong>of</strong> Excessive Noise<br />

Key Variable<br />

Additional Factors<br />

Proximity to residence Direction and elevation <strong>of</strong> residence in relation to Project<br />

Prevailing wind conditions<br />

Nature <strong>of</strong> construction and materials <strong>of</strong> residence<br />

Sensitivity and/or attitude <strong>of</strong> the resident(s) towards the Project<br />

Work habits <strong>of</strong> resident(s) (e.g. shift workers)<br />

Nature <strong>of</strong> Project Activity Elevation <strong>of</strong> active area or activity<br />

Hardness <strong>of</strong> materials being excavated<br />

Number and nature <strong>of</strong> operating machinery<br />

Operating hours<br />

Location, elevation and orientation <strong>of</strong> the primary plant in the<br />

pit<br />

Mine Vehicle Performance Changes to Project equipment<br />

Noise reduction measures vs performance reduction<br />

Engine and exhaust noise vs transmission noise<br />

Operator style and awareness/consideration<br />

Frequency and extent <strong>of</strong> equipment maintenance<br />

Production benefits vs noise control costs<br />

Background Noise Sensitivity/awareness <strong>of</strong> traffic and other noise<br />

Interference with performance monitoring<br />

Weather Conditions Wind speed and direction<br />

Cloud cover and height<br />

Temperature inversions<br />
