If your site is in the Development High Risk Area, for most forms of development you must submit a Coal Mining Risk Assessment to your Local Authority.
The exemptions list
Part A – Exempt by type of application
Types of application:
- householder development
- heritage consents, including listed building or conservation areas
- advertisement consent
- lawful development certificates
- hazardous substances consent
- tree or hedgerow works, tree preservation order or in conservation area
- prior notification
Part B – Exempt by nature of development
There are also exemptions for developments where building and/or ground works are minimal.
Examples of where groundworks are likely to be insignificant for development proposals include:
- bin stores and smoking shelters, as these are unlikely to require deep and extensive foundations or groundworks
- storage containers, as these are unlikely to require any groundworks as they are usually placed on existing site surface or on slabs
- solar arrays, as the solar panels are unlikely to require deep and extensive foundations or groundworks and are often merely placed on the site surface freestanding with adjustable legs
If you are in any doubt about whether you need to submit a CMRA with your planning application, the LPA will be able to advise you.
