Amendments to approved details

27.—(1) With respect to any requirement which requires the authorised development or any part of it to be carried out in accordance with the details, thresholds, plans or schemes approved under this Schedule, the approved details, thresholds, plans or schemes are, subject to sub-paragraph (2), taken to include any amendments or variations that may subsequently be approved in writing by the relevant planning authority in consultation with any other consultee specified in the requirement in question, or approved in writing by the relevant planning authority or another approval authority.

(2) Any amendments to or variations from any details, thresholds, plans or schemes approved pursuant to these requirements must be minor or immaterial and in order to obtain approval to such amendments or variations it must be demonstrated to the reasonable satisfaction of the relevant planning authority that the subject matter of the approval sought is unlikely to give rise to any materially new or materially different environmental effects from those assessed in the environmental statement.

Accident and emergency response

28.—(1) No phase of the authorised development may commence other than preliminary works until an accident and emergency response plan for that phase has been submitted to and approved in writing by the relevant planning authority.

(2) The accident and emergency response plan must be implemented as approved prior to commencement of development and maintained during the construction and operation of the authorised development.

Electrical output limitation

29.—(1) The authorised development must not be operated to generate a net electrical output of more than 1520MWe (1563MWe gross) unless and until the requirements set out in sub-paragraph (2) have been satisfied.

(2) The requirements referred to in sub-paragraph (1) are as follows—

(a) the undertaker has submitted to the Secretary of State a revised CCS proposal;

(b) The revised CCS proposal demonstrates that there is sufficient space available to comply with the land footprint requirement for the retrofitting of appropriate capture equipment for a generating station with a net electrical output of up to 1,700 MWe (1,748 MWe gross).

(c) The revised CCS proposal includes as a minimum—

(i) information required by the form “Environment Agency verification of CCS Readiness New Natural Gas Combined Cycle Power Station Using Post-Combustion Solvent Scrubbing”, as outlined in Annex C of the DECC Guidance, for a generating station with a net electrical output of more than 1,520 MWe (1,563 MWe gross) and up to 1,700 MWe (1,748 MWe gross); and

(ii) details demonstrating how the capture equipment will fit into the space allocated for the plant including the submission of engineering design details.

(d) The Secretary of State, in consultation with the Environment Agency, has approved the revised CCS proposal in writing.
