Details

National and international standards sometimes need supporting ‘Method implementation documents’ (MIDs) to make sure they are followed consistently. MIDs explain how to use the standards and guidance for regulatory monitoring when you are applying for a permit or complying with permit conditions.

The Environment Agency, Natural Resources Wales and Northern Ireland Environment Agency have produced this guidance to help holders and potential holders of permits. When we use the term ‘environment agencies’ in this guidance we mean these 3 organisations.

This MID supplements ‘BS 4142:2014+A1:2019 Method for rating and assessing industrial and commercial sound’ (BS 4142).

You must follow the requirements in this MID if you are:

  • applying to the environment agencies for a new environmental permit or applying to vary an existing permit
  • sending sound monitoring and assessments to the environment agencies – you must also follow the requirements of BS 4142 and the guidance Noise and vibration management: environmental permits
