EPA Issues Post-Construction Compliance Monitoring Guidance

EPA issued its final guidance on how to conduct effective post-construction compliance monitoring in order to assess the performance of measures implemented under long-term combined sewer overflow (CSO) control plans, as provided in EPA’s 1994 CSO Control Policy

The guidance will assist CSO permittees in developing post-construction compliance monitoring plans that collect sufficient data for evaluating the effectiveness of CSO controls and assessing compliance with the requirements of the Clean Water Act.

The EPA developed a draft of the guidance and received comments from state National Pollutant Discharge Elimination System authorities and other stakeholders.
