This matter is within the devolved responsibility of the Welsh Assembly Government. However, I understand the Environment Agency is still investigating who should be responsible for the cost of remediation. In doing so, it must ensure that it acts in accordance with the relevant legislation and statutory guidance. The contaminated land regime does not prescribe a timetable for completion of the investigation.
The Environment Agency had no original planned date for publication of its remediation option appraisal but it will place the information required by Regulation 15 and Schedule 3 of the Contaminated Land (Wales) Regulations 2001 on a public register.
The Environment Agency intends to place that information on the public register as soon as reasonably practicable after it is generated.
