the Authority shall act in accordance with the following general

procedures which are detailed in subsequent sections. The Authority

shall :-

(a)

identify the most affected Noise Sensitive Receiver, determine

the Area Sensitivity Rating for the area within which the Noise

Sensitive Receiver is located and hence determine the relevant

Acceptable Noise Level

Level (in accordance with Sections 2.1 to

2.6);

calculate the Corrected Noise Level which will be generated by

the work at the Noise Sensitive Receiver (in accordance with

Sections 2.7 to 2.12); and

compare the

Corrected Noise Level with the Acceptable Noise

Level to determine if a Construction Noise Permit may be issued
