Toolkit of Resources to Provide States with Flexibility in Adopting and Implementing Numeric Nutrient Criteria

EPA has developed a toolkit that provides all available Agency resources to facilitate state adoption of numeric nutrient criteria. Toolkit of Resources to Provide States with Flexibility in Adopting and Implementing Numeric Nutrient Criteria presents states, territories, and tribes with the resources to address: criteria and standards development; water quality monitoring, assessment, reporting, and planning; permitting, WQBELs, and trading; economics and financing; and communications materials. This dynamic toolkit will be updated as new Agency materials are developed.

The Association of Clean Water Administrators (ACWA) has developed a companion Nutrient Toolkit page, where state materials—similar in content to the Federal materials on this EPA toolkit—will be housed. ACWA’s preliminary state toolkit was developed in partnership with the EPA.

For further information on states' and territories' progress in adopting numeric nutrient criteria see our State Development of Numeric Criteria for Nitrogen and Phosphorus Pollution website, and for information on state nutrient data, see the Nutrient Indicators Dataset.
