1.4 General Introduction to the Procedures
For the purpose of determining if a Construction Noise Permit for
percussive piling should include restrictions on the hours during which
percussive piling may take place (referred to in this Technical
Memorandum as the permitted hours of operation) 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 and determine
the appropriate Acceptable Noise Level (in accordance with Sections 2.1
and 2.2);
(b) calculate the Corrected Noise Level which will be generated by the
percussive piling at the Noise Sensitive Receiver (in accordance with
Sections 2.3 to 2.8); and
(c) determine the appropriate permitted hours of operation for the
percussive piling by comparing the Corrected Noise Level with the
Acceptable Noise Level (in accordance with Sections 2.9 and 2.10).
The Construction Noise Permit issued by the Authority shall include the
permitted hours of operation as a condition, and may include such other
conditions as the Authority considers appropriate, such as the
permissible piling methods and pile types which may be used,
the area
within which percussive piling may take place (referred to in this
Technical Memorandum as the piling zone), the dates of commencement and
expiry of the Construction Noise Permit and any special noise control
measures that must be adopted.
A Construction Noise Permit may be issued for an initial period of such
duration as the Authority considers appropriate, and may be renewed
before or after the date of expiry for such further period or periods
and subject to
to such alterations or new conditions as the Authority
considers appropriate.
