Paragraph 24 Control of noise - operation
No part of the authorised development may be brought into commercial use until a scheme for management and monitoring of noise during operation of the authorised development has been submitted to and approved by the relevant planning authority.
Noise (in terms of the BS4142:2014 rating level) from the operation of the authorised development must be no greater than equal to the defined representative background sound level during the daytime and no greater than +5dB different to the defined representative background sound level during the night time adjacent to the nearest residential properties at such locations as agreed with the relevant planning authority.
The scheme submitted pursuant to sub-paragraph (1) must include a report setting out the extent to which the undertaker is able to achieve lower night time noise levels than those set out in sub-paragraph (2) and an explanation as to the levels that can be achieved.
The scheme must be implemented as approved unless otherwise agreed with the relevant planning authority.
In this requirement “daytime” means the period from 0700 to 2300 and “night time” means the period from 2300 to 0700.
