Unless otherwise agreed by the Local Planning Authority 'LPA', development other than
that required to be carried out as part of an approved remediation scheme must not
commence until phases i) to iv) have been complied with, or further works have been
deemed unnecessary as a result of conclusions based on risk assessments during phases
i) or ii), and this has been agreed upon in writing by the LPA.
Document(s) detailing the works undertaken in each phase must be submitted to and
approved by the LPA in writing before any other phase commences, and before occupation of any building in relation to phase iv). All phases of investigation must be designed and conducted in accordance with DEFRA and the Environment Agency's 'Model Procedures for the Management of Land Contamination, CLR 11.
i) A preliminary risk assessment, including a site walkover and conceptual site
model detailing all potential contaminants, sources and receptors.
ii) An intrusive site investigation to assess the type, nature, extent and risk(s) of any contamination identified in ii), whether or not it originates on site. It is
recommended that the LPA are consulted on proposals.
iii) A detailed remediation scheme, to bring the site to a condition suitable for
the intended use. The scheme shall include all works to be undertaken, proposed remediation objectives and remediation criteria, a timetable of works and site management procedures. The scheme shall also ensure that after remediation the site will not qualify as Contaminated Land under Part 2A Environmental Protection Act 1990.
iv) Validation of the remediation scheme demonstrating the effectiveness of the remediation approved in iii).
If contamination is found during the course of development that was not previously
identified, the development must be halted on that part of the site to the extent specified by
the LPA and until the LPA are satisfied that all necessary phases above have been
undertaken.
Reason: To ensure that risks from land contamination to future users of the land and neighbouring land are minimised, together with those to controlled waters, property and ecological systems, and to ensure that the development can be carried out safely without unacceptable risks to workers, neighbours and other offsite receptors in accordance with policy EP8 of the adopted South Oxfordshire Local Plan and with the principles of the National Planning Policy Framework 2012.
