Land and groundwater contamination

8.—(1) No part of the authorised development is to commence until a contamination risk assessment in respect of controlled waters has been produced for that part which is to include details of—

(a) any existing sources of contamination within the Order limits that may be affected by the carrying out of the authorised development;

(b) any reasonably required protective measures to ensure that the carrying out of the authorised development does not make worse any adverse conditions or risks associated with such existing sources of contamination; and

(c) appropriate remediation strategies and mitigation measures to address any historic contamination which is shown to be having significant, unacceptable effects on the environment within the context of the proposed works,

and the assessment has been submitted to and approved by the Secretary of State following consultation with the Environment Agency.

(2) The steps and measures that are identified as necessary for the purposes of carrying out the authorised development in the assessment referred to in sub-paragraph (1) must be implemented as part of the authorised development.

(3) In the event that contaminated material, including impacted groundwater, is found at any time when carrying out the authorised development, which was not previously identified in the environmental statement, the undertaker must cease construction of the authorised development in the vicinity of that contamination and must report it immediately in writing to the Secretary of State, the Environment Agency and the relevant planning authority, and in agreement with the Environment Agency and the relevant planning authority undertake a risk assessment of the contamination, and sub-paragraphs (4) and (5) will apply.

(4) Where the undertaker determines that remediation is necessary, a written scheme and programme for the remedial measures to be taken to render the land fit for its intended purpose must be prepared submitted to and approved in writing by the Secretary of State following consultation with the Environment Agency and the relevant planning authority.

(5) Remedial measures must be carried out in accordance with the approved scheme.
