Coal mining risk assessment

All planning applications should be accompanied by a Development Stability Report where appropriate. To find out if one is needed for your site, visit The Coal Authority website. If one is needed, advice is available on the website on how to obtain one.

Having obtained the report, you should then consider whether you need a Coal Mining Risk Assessment, which is the document that assesses the impact of any former mining activity on your development, and contains any appropriate mitigation measures.

We will not be able to determine your application until those matters have been properly addressed.
