Operator Monitoring Assessment (OMA)

We introduced Operator Monitoring Assessment (OMA) to strengthen auditing of operators' self-monitoring arrangements. It covers monitoring of emissions to air and water from industrial installations regulated under the Environmental Permitting Regulations (EPR), and discharges from Water Utility sites that are subject to permits requiring Operator Self Monitoring (OSM) and Urban Waste Water Treatment Directive (UWWTD) self monitoring.

About OMA

OMA helps us assess operators' self-monitoring (including monitoring undertaken on behalf of operators by contractors) using a consistent and transparent approach. It also provides a driver for necessary improvements.
