Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, for what reason guidance from the Institute for Air Quality Management has been adopted for use in quarry (a) planning and (b) development control decisions.

Planning policy for minerals is set out in the National Planning Policy Framework. This is supported by Planning Practice Guidance, including details on how planning authorities should assess the environmental impacts of mineral extraction.

By law, planning applications for minerals and other development should be determined in accordance with the development plan unless material considerations indicate otherwise.

Technical guidance produced by non-government organisations may be a material consideration where it raises relevant issues. The law requires that the weight to be given to different material considerations in any particular case is a matter for the decision-maker.
