Monitoring regime updated

摘要

The Environment Agency (EA)'s regime for monitoring wastewater treatment (WwT) facilities has been updated with new guidance on how to carry out an Operator Monitoring Assessment (OMA). The guidance covers sites that discharge to water subject to the Environmental Permitting Regulations (EPR), Operator Self-Monitoring (OSM) and the Urban Wastewater Treatment Directive (UWWTD). Although the updated OMA guidance is primarily intended for use by EA staff, it can also be used by site operators to prepare for inspections. The biggest change in the new version of the guidance document, Guidance on undertaking an OMA of discharges to water subject to Operator Self-Monitoring and UWWTD self-monitoring -Version 2, removes a previous requirement for five-yearly UWWTD audits at sewage treatment works that are subject to UWWTD self-monitoring. Instead it introduces a requirement to carry out a UWWTD OMA each year.
