These Standing Principles on Nutrient Reduction were developed by State staff through ACWA’s Nutrient Policy Committee and a series of discussions at ACWA’s Nutrient Permitting Workshops, held over 2017 – 2023. The discussions held throughout this process prodded states and EPA to identify challenges & barriers to nutrient permitting program implementation, improve effectiveness of nutrient reduction approaches, including market-based efforts, clarify roles and responsibilities of the water quality standards, 303d/TMDL and NPDES programs, build stronger links between those programs and others, such as monitoring, modernize permitting and data management, and identify program areas where targeted technical assistance and technology transfer would be most beneficial.
These principles were drafted as a reflection of the diverse state perspectives on water quality standards, permitting and on-ground implementation through regulation, infrastructure investment and operational optimization. As such, these principles are intended to be a resource for State nutrient reduction strategies with innate flexibility, allowing States to select certain principles and customize them to fit each State’s philosophy and strategic direction on nutrient reduction.
