Online Technical Support for States: N-STEPS


The Nutrient Scientific Technical Exchange Partnership and Support website is a series of pages developed to supplement the EPA's Office of Water Nutrient Criteria program, run through the Health and Ecological Criteria Division (HECD).

N-STEPS (Nutrient Scientific Technical Exchange Partnership and Support) Exitprovides direct support for nutrient criteria development. This site is a "One Stop Shop" for national, regional, and local nutrient criteria developments. The types of assistance available from N-STEPS include:

  • read questions and responses about the science of nutrient criteria development, as well as implementation questions,
  • see presentations by state nutrient experts and water quality managers,
  • participate in webcasts,
  • participate in nutrient related discussion boards,
  • view a bulletin board of recent nutrient happenings in other regions as well as at Headquarters,
  • and download factsheets and guidance documents on nutrient water quality criteria issues such as:
    • Nutrient-algal dynamics
    • Sampling design for determining ecosystem specific nutrient algal dynamics
    • Statistical analysis of data to assess nutrient-algal dynamics
