On April 11, 2022, EPA released the Compendium of State and Regional NPDES Nutrient Permitting Approaches (pdf). The compendium is a collection of state practices for controlling the adverse effects of nutrient pollution through NPDES permits. It is divided into the following sections: Permitting Critical Conditions, Performance Based Approaches, Water Quality Trading, and Watershed-Based Permitting. The Compendium responds to states’ requests that EPA compile different state approaches in order to facilitate state-to-state information sharing. The Compendium is a component of Radhika Fox’s April 5, 2022, memo Accelerating Nutrient Pollution Reduction in the Nation’s Waters, which identifies several governing principles and strategies to continue reductions in nutrient pollution.
