The Council only carries sites forward for detailed inspection where there is strong evidence of the significant possibility of significant harm and there are no alternative options within our approach to managing land affected by contamination to address the risks. Detailed inspections can be lengthy and costly and central government funding of Part IIA investigations was withdrawn in 2014. The Council will prioritise the detailed inspection of sites where risks to human health are greatest.

The detailed inspection process involves a comprehensive site assessment which follows the phased, risk-based approach specified under Land Contamination Risk Management Guidance (LCRM), as outlined below:

1. Preliminary risk assessment

The preliminary risk assessment is a desk-based exercise that looks at site data, regulatory information and historical maps to evaluate potential risks and determine the need for further assessment.

2. Generic quantitative risk assessment

A generic quantitative risk assessment evaluates potential risks using information collected during a site investigation, including taking environmental samples for analysis.

If the assessments indicate that all risks are low, the Council will exit the detailed inspection process. Where risks are considered high, or there is uncertainty, further assessment is required through a detailed quantitative risk assessment.

3. Detailed quantitative risk assessment

Detailed quantitative risk assessment requires site specific assessment criteria to be developed to assess the level of risk from contamination to help confirm whether the contamination poses a significant risk. This is a highly technical process that requires specialist skills and software.

A site prioritised for detailed inspection will be investigated and assessed until such a point where it can be categorised and determined as either contaminated land or not contaminated land. Inspection activities will stop at any stage where the Council decides there is insufficient evidence that the land might be contaminated.

Specialist land contamination consultants would be selected to carry out this work on behalf of the Council. Selected consultants will be suitably qualified, competent and experienced to undertake the work.
