Operator monitoring assessment: environmental permits

Guidance on how we assess the quality of your monitoring procedures through an operator monitoring assessment (OMA) and what you can do to prepare.

Applies to England



Your environmental permit tells you what emissions to air and discharges to water you have to monitor. The Environment Agency checks you are doing it properly using an operator monitoring assessment (OMA).

We carry out OMAs on installations we regulate under the Environmental Permitting (England and Wales) Regulations 2016.

This guidance explains the process and how you can prepare for an OMA.
