Please see below feed back provided in relation to the currently submitted unacceptable Land Contamination information (pertaining condition No. 10A). This is as follows:
We have reviewed the GEA Remediation Statement letter dated 17 July 2023 against RBKC s advice, provided under PP/23/00558 and comment as follows:
Verification of site won or imported materials: The general screening criteria referred to within the second paragraph have not been attached. Could the criteria be attached to an updated letter to be submitted as part of any further submission.
Buried Plastic Services: If the development will include the re-laying of any water supply pipes, we would prefer that, unless soil contamination is encountered, that the installation is undertaken in consultation with Thames Water and that full details of the services installed are provided. If soil contamination is encountered, we would need to be contacted as necessary under the 'unknown contamination provisions.
Soil Gas & Vapours / Radon: GEA recommended, within their Desk Study and Ground Investigation Report, that 'Details of the proposed waterproofing and demonstration of how these measures meet the requirements for basic radon protection, as set out in BRE11, should be provided to the local authority'. Insufficient information has been provided. Ideally any information should be attached to the submission letter or reports.
Unexpected contamination: The requirements set out are more rigorous than what is required within the CLC3 guidance. For example, we specify works in the affected area, rather than all work. According to the condition/CLC3 guidance the Council should be contacted within 2 days of unexpected contamination being uncovered. Obviously if contamination was more significant we would expect to be contacted within this timescale, rather than after GEA had been contacted and testing had been undertaken. I would suggest that you check the requirements of the CLC3 condition/guidance and update this section.
ÿIn conclusion, it is not possible to discharge condition 10A at the present and the applicant is recommended that a satisfactorily updated remediation statement is submitted as part of a fresh submission addressing condition 10A. It should be noted that it will not be possible to discharge the other parts of the condition at that initial implementation point.
Land contamination gardenÿinformative: As much of the borough is covered by made ground, which is often contaminated with substances such as lead and asbestos, it is recommend that the applicant considers undertaking soil sampling in parts of the garden not covered by the basement, to check whether contaminants are above recommended levels within soils. This particularly applies to areas of soft landscaping, but is also relevant to hard surfaced areas, which may be removed in the future. Guidance on undertaking soil sampling is available within the Council's CLC2 guidance for small-scale sampling. If you have any questions, please contact the Royal Borough's Contaminated Land Officer (Pollution Regulatory Team) (Tel: 020 7361 3002 email: [email protected]).
