No phase of development hereby approved shall take place until further details which are based upon the recommendations set out in the Phase 2 Environmental Site Assessment (Shallow Soils), Arcadis, August 2020 and the Outline Remediation Strategy, Wood, June 2019 have been submitted to and approved by the Local Planning Authority. These details shall include:
• An assessment of deep soils, ground and surface water to further assess the risks to Controlled Waters at the site, and the risks to human health from the vapour intrusion pathway;
• A further assessment of the risk to identified surface water receptors from concentrations of CoC identified in groundwater; and
• A remediation options appraisal for the loose asbestos fibres identified in the Made Ground on the site. Additional data collection may be needed to support the associated risk assessment/remediation design.
REASON: To ensure that risks from land contamination to the 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.
REASON FOR PRE-COMMENCEMENT: The information is required prior to any works commencing on site as it relates to earth works which are often the first works on site and relate to site preparation.
