Sponsor: Rep. Doudera (Camden)
Committee: Environment and Natural Resources
Final legislative action: Passed, as amended by Committee Amendment "A" (H‑606), and enacted.

Purpose and intent

LD 497 is legislation that revises certain powers and provisions relating to the Maine Department of Environmental Protection (DEP). In its engrossed form the bill specifically addresses the regulation of significant vernal pools under the Natural Resources Protection Act (NRPA). The stated intent is to modify how significant vernal pools are regulated within the NRPA framework and to adjust relevant DEP authorities and procedures tied to that regulation.

Key provisions (high level)

  • Revises DEP-related statutory provisions and powers (exact statutory changes not provided in the summary documents).
  • Specifically alters how "significant vernal pools" are regulated under the NRPA (engrossed version identified as focusing on vernal pools).
  • Enacted with Committee Amendment "A" (H‑606); the amendment was read and adopted in both chambers prior to final passage.

Note: The provided documents do not include the full text of the bill or amendment language. For precise statutory changes (definitions, permitting requirements, exemptions, mapping or mitigation rules, enforcement mechanisms, etc.), consult the final enrolled/printed bill (text of H‑606 / LR 1932(03)).

Who is affected

  • State agencies: Maine Department of Environmental Protection and Department of Inland Fisheries and Wildlife (DEP and IFW) — responsible for implementing the regulatory changes.
  • Landowners, developers, consultants, and municipalities — those undertaking land use activities that could affect vernal pools or that interact with NRPA permitting.
  • Conservation organizations and natural resource stakeholders — interested in protection and classification of vernal pools and associated species habitat.
