Compliance and Annual Biosolids Reporting
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.
Treatment works that meet applicability requirements and either land apply, surface dispose, or incinerate sludge are required to submit an annual report to their permitting authority by February 19 of each year. These requirements apply to facilities if the design flow rate is equal to or greater than one million gallons per day, they serve 10,000 or more people, are required to have an approved pretreatment program (Class I Sludge Management Facility), or are otherwise required to report. Electronic biosolids reporting began in 2017 which covered data from 2016.
Reports are collected from the 41 states where EPA implements the federal Biosolids Program. There are currently nine states (Arizona, Idaho, Michigan, Ohio, Oklahoma, South Dakota, Texas, Utah, and Wisconsin) which are authorized through the NPDES Program to be the permitting authority for biosolids. EPA will transition to electronic reporting for the remaining authorized states as part of Phase 2 implementation of the NPDES eRule.
