Chapter 583: Nutrient Criteria for Class AA, A, B, and C Fresh Surface Waters

Ch 583 Fact Sheet :: Ch 583 Draft Rule :: Description of Draft Nutrient Criteria :: Comment on this Rule

Concise Summary:

The Department is proposing the new chapter 583 to establish methods to address nutrient enrichment in certain fresh surface waters of the state. 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 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.

Chapter 305 Natural Resources Protection Act - Permit by Rule Standards and Chapter 310 Wetlands and Waterbodies Protection

Ch 305/310 Fact Sheet (pdf) :: Ch 305 Draft (pdf) :: Ch 310 Draft (pdf) :: Comment on this Rule

Concise Summary:

The Department is proposing to amend the Chapter 305 Natural Resources Protection Act (NRPA) Permit by Rule Standards and the Chapter 310 Wetlands and Waterbodies Protection rules in order to:

  • encourage nature-based shoreline stabilization methods using vegetation and biodegradable stabilization materials;
  • place appropriate limits on the use of hardened stabilization structures like riprap and seawalls to ensure project impacts are reasonable and to address cumulative impacts; and
  • simplify and speed up the permitting process for applicants and the Department.

The proposed rule changes would also implement two laws passed by the 131st Legislature, which allowed for the use of biodegradable stabilization methods for sand dune restoration (P.L. 2023 ch. 97) and allowed for increasing the height of piers, wharves and docks when these structures are replaced through permit by rule (P.L. 2023 ch. 531). Other proposed changes include expanding the non-development activities allowed through permit by rule in coastal sand dune systems, increasing the time limit for processing NRPA permit by rule applications to the statutory timeline of 20 working days, and updating erosion and sedimentation control standards throughout Chapter 305 to reflect current best practices.

Chapter 375: No Adverse Environmental Effect Standards of the Site Location of Development Act

Ch 375 Reposting Fact Sheet :: Ch 375 Reposting Draft Rule :: Ch 375 Reposting Changes :: Comment on this Rule

Concise Summary:

Update: New layers are available on the Habitat Connectivity Map. As an aid for visualizing different ways to define large undeveloped habitat blocks in Western, Northern and Downeast Maine, the Department has added layers showing distances of 0.5, 1, and 2 miles from all roads (those available in the E911 database) and from paved public roads. For context, the Department also added available data from the Department of Inland Fisheries and Wildlife showing essential habitats, Natural Resource Protection Act habitats and habitats of endangered species, threatened species, and species of special concern. To turn layers on and off, see the list of data layers in the upper right-hand corner of the map. Please note that this map is for illustrative purposes only; it is intended as guidance and may contain errors. Please also note that some layers may take time to load.

In P.L. 2023 ch. 448, the Legislature directed the Department to establish a compensation fee program for renewable energy development projects, specifically solar energy development, wind energy development, and high-impact transmission lines that trigger the Site Location of Development law. The new statute requires this program to allow for the payment of a compensation fee when the Department determines that off-site habitat improvement or preservation is necessary to mitigate the adverse effects of a renewable energy development on large undeveloped habitat blocks, important wildlife corridors, and other habitat types identified in consultation with the Department of Inland Fisheries and Wildlife.

The Department is proposing to amend Chapter 375, No Adverse Environmental Effect Standards of the Site Location of Development Act, to define these habitat resources and establish a compensation fee program. The Department held a public hearing on the first iteration of this proposed rule on March 7, 2024 and received written comments through March 18, 2024. On June 6, 2024 the Board of Environmental Protection held a deliberative session to consider the proposed rule. Based on public comments and Board deliberations the proposed rule was revised in various ways, including reducing compensation ratios (except for endangered and threatened species habitat), allowing for term easements, eliminating migratory bird pathways, changing the definition of large undeveloped habitat blocks outside of Southern and Central Interior and Midcoast Maine, and adjusting the way land values are determined.

The Department is particularly interested in public comments regarding the definition of large undeveloped habitat blocks in Western, Northern and Downeast Maine (outside of the Southern and Central Interior and Midcoast ecoregions), the appropriateness of the proposed compensation ratios, and the potential for the use of term easements or deed restrictions as a form of compensation. A map intended to help understand the proposed amendment is available.
