(B) Where mean concentrations of a contaminant within the soil over a part of or the whole of a site exceed generic or detailed quantitative risk assessment criteria (RAC), a remediation strategy (RS) will be produced.
(C) Any approved RS shall be fully implemented and a verification report (VR) will be produced.
(D) A description and on-site sampling and laboratory analyses of imported or site sourced soils and fills (ASF) will be provided demonstrating that these materials are suitable for use.
Where physical remedial measures are implemented to protect end-users of the development they shall be maintained. The EHI, SAE, SAE Report, RS, VR, ASF and any actions to address unexpected contamination, identified during the SAE and development, shall be undertaken in line with the Council's contaminated land guidance for GLY areas.
