Paragraph 12 Ground conditions
No part of the numbered works 1, 2, 3, 5 and 7 is to commence (including permitted preliminary works comprising demolition of existing structures, remedial work in respect of any contamination or other adverse ground conditions or the diversion and laying of services) until a written strategy in relation to the identification and remediation of any risks associated with the contamination of the Order limits associated with that numbered work has been submitted to and, after consultation with the Environment Agency, approved by the relevant planning authority.
The strategy submitted and approved pursuant to sub-paragraph (1) must—
include a site investigation scheme, based on the preliminary risk assessment set out in appendix 11.1 of the environmental statement and providing details of the detailed risk assessment to be carried out for the receptors on or in the vicinity of the Order limits that may be affected by the authorised development;
set out how the outcomes of the site investigation scheme and detailed risk assessment carried out pursuant to sub-paragraph 12(2)(a) above will be reported, and provide for the submission and approval by the relevant planning authority of an options appraisal and remediation strategy based on such outcomes and providing details of any remediation measures required and how they are to be carried out;
include an earthworks specification setting out protocols for testing and limiting values to ensure that imported materials are suitable for their intended use in terms of their chemical or geotechnical quality; and
include a verification plan identifying the data to be collected in order to demonstrate that the remediation measures set out in the options appraisal and remediation strategy prepared pursuant to sub-paragraph 12(2)(b) above have been completed and are effective, and any requirement for long term monitoring of pollutant linkages, maintenance or arrangements for contingency action.
Prior to the date of Unit 1 full commissioning a report prepared substantially in accordance with the verification plan prepared pursuant to sub-paragraph 12(2)(d) and approved pursuant to sub-paragraph 12(1) must be submitted to and, after consultation with the Environment Agency, approved by the relevant planning authority.
If, during the carrying out of numbered works 1, 2, 3, 5 and 7 contamination not previously identified is found to be present within such area(s) no further development (unless otherwise agreed in writing with the relevant planning authority) must be carried out on the area(s) on which the contamination has been found until a remediation strategy detailing how such contamination must be dealt with has been submitted to and, after consultation with the Environment Agency, approved by the relevant planning authority.
No piling works comprised in the numbered works 1, 2 and 3 must commence until a piling risk assessment has been submitted to and approved by the Environment Agency.
The piling risk assessment approved by the Environment Agency under sub-paragraph (5) must be provided to the relevant planning authority before commencement of numbered works 1, 2 and 3.
