C.M.R. 06, 096, ch. 583 - NUTRIENT CRITERIA FOR CLASS AA, A, B, AND C FRESH SURFACE WATERS

  1. § 096-583-1 - Purpose and applicability
  2. § 096-583-2 - Definitions
  3. § 096-583-3 - Nutrient criteria
  4. § 096-583-4 - Implementation
  5. Appendix 096-583-1

SUMMARY: This Chapter establishes nutrient criteria for Class AA, A, B, and C fresh surface waters of the State of Maine. Nutrient enrichment can cause negative environmental impacts to surface waters-such as algal blooms, low dissolved oxygen concentrations, excessive growths of filamentous algae or bacteria, and generation of cyanotoxins-or affect the resident biological community. The Department of Environmental Protection (Department) will use the methods described in this Chapter to make decisions about attainment of designated and existing uses of aquatic life support, habitat, and recreation in and on the water of surface waters established in the State's water quality classification system ( 38 M.R.S. §§ 464-470). This Chapter also sets forth a framework to identify and establish site-specific phosphorus and other nutrient criteria through additional rulemaking.
