1.4 General Introduction to the Procedures
For the purpose of assessing if a Construction Noise Permit may
be issued for work other than percussive piling during restricted hours
the Authority shall act in accordance with the following general
procedures which are detailed in subsequent sections. The Authority
shall :-
(a)
(b)
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
(c)
compare the
Corrected Noise Level with the Acceptable Noise
Level to determine if a Construction Noise Permit may be issued
(in accordance with Section 2.13).
