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

To ask the Secretary of State for Housing, Communities and Local Government, what assessment she has made of the potential impact of redeveloping former gasworks sites on trends in air pollution levels in the surrounding area.

The handling of hazardous materials is strictly regulated to prevent and limit the consequences of major accidents and to ensure that communities and the environment are protected. Hazardous substances consent is required for the presence of hazardous substances at or above specified limits set out in regulations. Planning Practice Guidance on Hazardous Substances provides advice on this matter. The Health and Safety Executive is a statutory consultee on hazardous substance consent applications and provides expert advice to local planning authorities on any risks to inform their decision making.

There are strong existing protections in national planning policy to safeguard people from unacceptable risks from air pollution and site decontamination. These will be material considerations for a local council when determining a planning application, as will the planning concerns of the local community.
