Re-Classification of Maine Waters: More Information

Some things to keep in mind

• Maine 's Water Quality Classification System is goal-based.

Proposals for upgrade in classification commonly recommend waters that either presently attain or with reasonable application of improved treatment or Best Management Practices (BMPs), could reasonably be expected to attain, the standards and criteria of a higher proposed class .

• In Classes AA, A and SA Maine law places significant restrictions on human activities that might pose a risk of degradation of water quality. More allowances for human activities are permitted in Classes B, C, SB and SC. For example Class AA prohibits wastewater discharge and hydropower while Class C allows these activities.

The interests and activities of other users of the resource, and how the proposed change may affect them, are taken into account when considering a waterbody for upgrade in classification.

• Downgrades are only approved by the Department and the United States Environmental Protection Agency when it can be proven that it is impossible for the waterbody to attain its assigned standards and criteria. For more information about downgrading a waterbody please contact Susan Davies directly.
