EPA works with its federal, state and tribal regulatory partners to monitor and ensure compliance with clean water laws and regulations in order to protect human health and the environment. The Clean Water Act is the primary federal law governing water pollution. You may find additional information of interest regarding EPA's enforcement and compliance and how to report a violation at these links.
If you are a publicly owned treatment works that meets the applicability requirements and your sewage sludge is land applied, surface disposed, or you operate a sewage sludge incinerator, you will need to submit an annual report by February 19 of each year covering the previous year. Your facility will meet the applicability requirements if your facility’s design flow rate is equal to or greater than one million gallons per day, serves 10,000 people or more, or is required to have an approved pretreatment program (Class I Sludge Management Facility).
EPA's Biosolids Center of Excellence (Region 7, Lenexa, KS) receives and reviews these annual reports. EPA has now started to electronically collect these reports in the 42 states where EPA implements the Federal Biosolids Program (see NPDES State Program Information). EPA will transition to electronic reporting for the remaining eight states (Arizona, Michigan, Ohio, Oklahoma, South Dakota, Texas, Utah, and Wisconsin) no later than 21-December 2020. Please see the following webpages for more information about NPDES electronic reporting.You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
