The Welsh Affairs Committee writes to the Deputy First Minister and Cabinet Secretary for Climate Change and Rural Affairs seeking follow-up information on Wales' industrial legacy, specifically regarding coal tip remediation costs, the new Disused Tips Authority, contaminated land legislation, and the application of the 'polluter pays' principle. The Deputy First Minister responds that over £230 million has been secured (including £143m from UK Government) to support a multi-year tip safety programme to 2029, the Disused Tips Authority will become operational in April 2027, and contaminated land is managed under existing Environmental Protection Act provisions with 22% of remediation costs recovered from original polluters.
