State Technical Standards for Nutrient Management

40 CFR 123.36 requires states to establish technical standards for nutrient management. These standards are to be used by CAFOs when developing nutrient management plans to meet NPDES permit requirements. The standards will also be used by EPA to evaluate whether discharges from a CAFO’s land application area qualify for the Clean Water Act agricultural stormwater exemption. EPA has established a set of minimum criteria that should be addressed by a state’s technical standards for nutrient management. To find the standards for a specific state or territory, select the name of the state or territory from the drop-down list below. The table provided in the search results identifies EPA’s technical standards criteria and provides references to the state-specific standards that address those criteria. Comments have been added to clarify how the state addresses certain criteria.

EPA is in the process of working with the states to have technical standards posted on this site. As of January 2014, 19 states have been added. Please note that the links below should open to the specific location of the technical standard.
