Construction of Work Nos. 6a and 6b adjacent to the North Killingholme Haven Pits, as shown on drawing 64042B-DCO-48, shall not take place except in accordance with a scheme that has been submitted to and approved by the relevant planning authority in consultation with Natural England in advance of such works.

The approved scheme shall address the period outside the months January to March (January to March inclusive being the only months in which piling may occur) and shall have the objective that the rating level of construction noise from the construction of Work Nos. 6a and 6b adjacent to the North Killingholme Haven Pits shall not exceed both the LAeq rating level and the mean LAmax rating level as listed in the following table in any 12 hour period except in case of emergency or unless otherwise as approved by the relevant planning authority, in consultation with Natural England.

Compliance with the above limits shall be deemed to be achieved through compliance with a programme of attended noise monitoring and periodic site noise audits and equipment condition reviews pursuant to the approved scheme.

The monitoring of noise pursuant to this requirement shall be compliant with the requirements of ISO 1996 Part 2 (2007).

The mean LAmax will be calculated as the logarithmic average of LAmax values recorded at NSR A using a Class A integrating sound level meter, with a 15-minute sampling period, operating continuously throughout the entire construction day. In processing the recorded data to calculate the mean LAmax, the dataset over the course of the construction day could show “sampling periods of no construction activity”. These “sampling periods of no construction activity” will not be included in the mean LA max calculation.
