The Hinkley Point C (Nuclear Generating Station) Order 2013

6.  For the purpose of requirements CW1 and CW2, the “site” refers to the limits of deviation for Work Nos. 2A, 2C, 2E and 2G as shown on sheet nos. 3 and 4 and “development” refers to Work Nos. 2A, 2B, 2C, 2D, 2E, 2F, 2G and 2H. Requirements CW1 and CW2 relate only to development carried out on the site as so defined.

(1) Reference No.	(2) Requirements
CW1	Cooling water infrastructure design
	(1) No development shall commence until details of Work Nos. 2A to 2H have, following consultation with the Countryside Council for Wales, Natural England, English Heritage and the Environment Agency, been submitted to and approved by the Marine Management Organisation. The details shall include—
	(a)	the location and design (size and shape) of the off-shore intake and outfall heads;
	(b)	the alignment (horizontal and vertical) of the cooling water intake and outfall tunnels; and
	(c)	the location and design of the fish recovery and return system and the low velocity side entry intakes, which shall be in accordance with the Environment Agency guidance referenced in the Environmental Statement (Volume 2, chapter 2, paragraph 2.6.21).
	(2) The acoustic fish deterrent system shall not be installed until details of the location and design have, following consultation with the Countryside Council for Wales, Natural England and the Environment Agency, been submitted to and approved by the Marine Management Organisation.
	(3) No water abstraction shall commence until the off-shore intake and outfall heads, cooling water intake and outfall tunnels, the fish recovery and return system, the low velocity side entry intakes and the acoustic fish deterrent system have been installed in accordance with the approved details referred to in paragraphs (1) and (2).
CW2	Monitoring and adaptive measures
	(1) No water abstraction shall commence until a monitoring and adaptive measures plan for Work Nos. 2A to 2H has, after consultation with the Countryside Council for Wales, Natural England and the Environment Agency, been submitted to and approved by the Marine Management Organisation. The purpose of the plan shall be to ensure that the acoustic fish deterrent system minimises the impacts of water abstraction on the relevant fish populations, having regard to the conservation objectives of the Severn Estuary SAC and other relevant ecological considerations. The plan shall set out—
	(a)	the performance level to be maintained by the acoustic fish deterrent system associated with the cooling water intakes to be confirmed through trials and the fish recovery and return system, during the operation of Unit 1 and Unit 2;
	(b)	the monitoring arrangements for the trialling of the acoustic fish deterrent system and the fish recovery and return system during commissioning of Unit 1 and Unit 2, in respect of the performance levels set in (a);
	(c)	the monitoring arrangements for the acoustic fish deterrent system and the fish recovery and return system during operation of Unit 1 and Unit 2, in respect of the performance levels set in (a);
	(d)	the additional adaptive measures arising from (a), (b) and (c) and reflecting the contents of Appendix 5: Adaptive Management and Contingency Measures, section 1.3.9 (submitted 6th August 2012 as part of EDF Energy – Response to Issues Raised at the Second Issues Specific Hearing), that the Marine Management Organisation may require to be adopted during operation of Unit 1 and Unit 2 to meet or improve on the performance levels agreed under (a); the conditions where such measures would apply; and the process for their implementation; and
	(e)	the monitoring methodology, frequency of monitoring and format of monitoring reports.
	(2) The plan shall be implemented in accordance with its terms.
