Cause of Impact

Construction

The main source of noise from the construction and operation of the temporary barging point at Telegraph Bay is the use of Powered Mechanical Equipment (PME).

Operation

Barging point facilities at Telegraph Bay will be removed on completion of SIL(E) construction.

Proposed Remedies

Construction

In order to reduce noise levels at the temporary barging point, the following remedies will be applied:

• Ensuring that the noise standards set by the Technical Memorandum on Environmental Impact Assessment Process (EIAO-TM) are met as far as practicable;
• Obtaining a Construction Noise Permit (CNP) for PME use in restricted hours;
• Using well-maintained PME and ensuring that PME are regularly serviced during the construction stage;
• Shutting down (or throttling down to minimum) noisy PME between work periods;
• Positioning PME so that noise is directed away from sensitive areas;
• Using silencers or mufflers on construction equipment;
• Using movable noise enclosures with PME, wherever possible;
• Using quieter PME, fitted with noise insulating fabric where relevant;
• Using temporary or permanent noise barriers/acoustic shields with PME wherever possible;
• Using stockpiles and other structures to screen noisy activities; and
• Conducting regular site audits to ensure that noise control measures are properly implemented.

Results

Applying the various remedies described above will result in the levels of noise from the construction and operation of the temporary barging point at Telegraph Bay fully complying with the noise standards stipulated in the EIAO-TM.
