Noise data has been measured in accordance with the appropriate British Standard guidelines. Noise level projections have been completed in accordance with both the procedure and noise propagation correction terms provided in EN ISO 9613:1996: Attenuation of Sound During Propagation Outdoors.   The highest predicted level of daytime construction noise at the closest residential position of Mariners Point, is LAeq (1 hour) 54 dB, which is 3 dB above background levels. The highest predicted level of daytime construction noise at the closest commercial position of Puckey House, is LAeq (1 hour) 57 dB, which is 7 dB above background levels. Construction works on the development are predicted to be within the guideline levels and will have a temporary and minor adverse affect. The noise limits set in terms of either an absolute noise limit of daytime LAeq (1 hour) 65 dB(A), or as an allowance of +10 dB(A) over existing daytime LAeq level. It is also relevant to note that the construction activities will be limited to the following hours: Monday – Friday: 0700 – 1900; and Saturday: 0800 – 1700. The Renewable Energy Plant operational noise levels will be 7 dB below background noise levels at the nearest sensitive residential location (Mariners Point). And the noise levels will be 2 dB below background noise levels at the closest commercial office building (Puckey House). At these levels, BS4142 standard indicates that noise from the Port Talbot Renewable Energy Plant is unlikely to cause any complaint. The highest predicted level of daytime noise from decommissioning works at Mariners Point is LAeq (1 hour) 57 dB. This noise level would provide only a minor adverse impact.
