5.7 Site Remediation and Monitoring Site remediation includes cuttings piles management, debris clearance and over-trawl surveys. Over-trawl surveys make sure the seabed is safe for normal fishing activities to resume. Monitoring is the very final stage of decommissioning, where operators must carry out surveys on the site after physical decommissioning has been completed. Details of these programmes are agreed on an individual basis with the Department for Business, Energy and Industrial Strategy.

Activity associated with site remediation and monitoring is not forecast in this report, however, estimated expenditure can be found in section 6.1.
