17.—(1) Following the date of final commissioning of numbered work 1, site-attributable noise attributable to numbered work 1 during the operational phase must be limited to the noise levels set out below measured at the coordinates set out below—

Noise Limit Sound Pressure Level, LAeq, 5mins dB	Coordinates
	X	Y
57	613272.4		275205.6
55	613214.4		275014.8
52	613131.2		275156.8

(2) Noise measurements at each of the identified locations must be undertaken in accordance with the equipment specifications, measurement procedures and monitoring equipment positioning guidelines outlined in sections 4, 5 and 6 (save for 6.3.5 and 6.3.6 which are not applicable) of BS 4142:1997. Measurements should be undertaken with the power plant running at base load. A single LAeq 5min measurement will be required at each identified location during the day, evening and night time periods identified as follows: daytime (0700hrs to 1900hrs), evening (1900hrs to 2300hrs) and night time (2300hrs to 0700hrs).

(3) Within three months of the date of final commissioning of numbered work 1, the undertaker must submit measurements to the relevant planning authority taken in the vicinity of the relevant locations specified at sub-paragraph (1) of this requirement, including details of any remedial works and a programme of implementation should the emissions exceed the levels specified at sub-paragraph (1) of this requirement.
