Opportunity for Comment
Triennial Review of Water Quality Standards
Comment deadline: June 30, 2025, 5:00 PM
The federal Clean Water Act requires that states periodically, but at least once every 3 years, hold public hearings for the purpose of reviewing water quality standards and, as appropriate, modifying and developing standards. Maine Statute contains similar language in 38 M.R.S. 464.3.B. This process, known as the Triennial Review, requires consultation with the public and interested state and federal agencies.
Under the Triennial Review, the Maine Department of Environmental Protection is preparing updates to water quality standards for the 132nd Legislature in accordance with 38 M.R.S. Section 464.3.B. The Department has compiled documentation containing its initial recommendations on proposals received in response to a request for proposals issued on March 18, 2024. This documentation is available for public comment until 5:00 PM, June 30, 2025. At a virtual meeting on Monday, June 23, 2025, from 9 a.m. to noon, the Department will provide an overview of the proposals and offer an opportunity to provide input. Register for the meeting
