Mr. Philip Nugent:

We have regular engagement with local authorities through the waste enforcement regional lead authorities. They have a shared service approach to enforcement action. On responsibility for monitoring and ongoing remediation of the sites, responsibility for the remediation of the specific sites rests with individual local authorities.

The overall strategic approach is taken through the regional waste management plans, which are due to be replaced in 2022 by a national waste management plan. That is the primary mechanism. There is also a steering group that meets on a quarterly basis to ensure we are on track, to monitor trends and to ensure we are moving through the risk sites on a prioritised basis.
