The question

To ask the Secretary of State for Housing, Communities and Local Government, what discussions he has had with the Secretary of State for Environment, Food and Rural Affairs on sites intended for building that have previously been used as dumps for fly ash.

Answered by Matthew Pennycook

The National Planning Policy Framework is clear that planning policies and decisions should ensure that a site is suitable for its proposed use taking account of ground conditions and any risks arising from land instability and contamination. This includes risks arising from natural hazards or former activities such as mining, and any proposals for mitigation including land remediation (as well as potential impacts on the natural environment arising from that remediation). My Department continues to work closely with the Department for Environment, Food and Rural Affairs on matters relating to meeting our shared ambition to deliver 1.5 million new homes in this Parliament while improving and protecting the environment.
