Ambient Water Quality Criteria Recommendations. Information Supporting theDevelopment of State and Tribal Nutrient Criteria. Wetlands in Nutrient Ecoregion XIII

摘要

This document presents EPA's nutrient criteria for Wetlands in Nutrient EcoregionXIII. These criteria provide EPA's recommendations to States and authorized Tribes for use in establishing water quality standards consistent with section 303(c) of CWA. Under section 303(c) of the CWA, States and authorized Tribes have the primary responsibility for adopting water quality standards as State or Tribal law or regulation. The standards must contain scientifically defensible water quality criteria that are protective of designated uses. EPA's recommended section 304(a) criteria are not laws or regulations-they are guidelines that States and Tribes may use as a starting point for the criteria for their water quality standards.
