Paragraph 11 I1

In the event that land affected by contamination, including groundwater, is found at any time when carrying out the authorised development which was not previously identified in the environmental statement, it must be reported as soon as reasonably practicable to the relevant planning authority and the Environment Agency, and the undertaker must complete a risk assessment of the contamination in consultation with the relevant planning authority and the Environment Agency.

Where the undertaker determines that remediation of contamination identified in, on, or under land from detailed site investigations, or as an unexpected discovery, 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 submitted to and approved in writing by the relevant planning authority, following consultation with the Environment Agency.

Any required and agreed remediation must be carried out in accordance with the scheme approved under sub-paragraph (2).

A verification plan providing details of the data that will be collected in order to demonstrate that the works set out in the remediation scheme approved under sub-paragraph (2) are complete and identifying any requirements for longer-term monitoring of pollutant linkages, maintenance and arrangements for contingency action must be submitted to and approved in writing by the relevant planning authority, following consultation with the Environment Agency.

Prior to any part of the authorised development being occupied a verification report demonstrating the completion of the works set out in the approved remediation scheme and the effectiveness of the remediation must be submitted to, and approved in writing by, the relevant planning authority. The report must include results of sampling and monitoring carried out in accordance with the verification plan approved under sub-paragraph (4) to demonstrate that the site remediation criteria have been met.
