Complete·3/30/26

Updates water quality standards and reclassifies certain waters in Maine based on recommendations from the United States Environmental Protection.

This bill updates water quality standards and reclassifies certain waters in Maine. It sets specific criteria for dissolved oxygen, pH levels, and bacteria content for different water classes. For example, Class C waters must maintain a 30-day average dissolved oxygen of 6.5 parts per million. The bill also mandates that the aquatic life in certain waters must remain as naturally occurring. Additionally, it reclassifies specific water bodies, such as Sandy River and its tributaries as Class AA, and Mount Blue Stream and its tributaries as Class AA.
