No part of the authorised development is to commence in the area around the High Marnham power station as shown hatched blue on the land and soils constraints plan included in the preliminary risk assessment at appendix 8.2 to chapter 8 of the environmental statement (“the area for site investigation”), until—
a Phase 2 site investigation and risk assessment methodology to assess the nature and extent of any contamination specifically located in the area for site investigation has been submitted to and approved by the relevant planning authority in consultation with the Environment Agency;
unless otherwise agreed in writing with the relevant planning authority, any Phase 2 site investigation and risk assessment for the area for site investigation has been completed in accordance with the methodology approved pursuant to sub-paragraph (a) and a written report including a remedial options appraisal, if required, has been submitted to and approved by the relevant planning authority in consultation with the Environment Agency;
unless otherwise agreed in writing with the relevant planning authority, a detailed remediation strategy that includes proposals (including any phasing) for remedial works and verification for such works for the area for site investigation has been submitted to and approved by the relevant planning authority in consultation with the Environment Agency;
If, during the carrying out of any part of the authorised development, contamination not previously identified is found to be present within such part, no further development (unless otherwise agreed in writing with the relevant planning authority) must be carried out on the part on which the contamination has been found until a remediation strategy detailing how such contamination must be dealt with has been submitted to and approved by the relevant planning authority in consultation with the Environment Agency.
The authorised development must be carried out in accordance with the strategy approved pursuant to sub-paragraph (1)(c).
For the purposes of sub-paragraph (1), “commence” includes part (d) (remedial work in respect of any contamination or other adverse ground conditions) and part (e) (diversion of existing services and the laying of temporary services) of the permitted preliminary works.
