Lewiston endorses DEP relicensing water‑quality certificate; staff warn future sewer‑rate impacts

The Lewiston City Council voted 7–0 to endorse a letter to the Maine Department of Environmental Protection supporting a water‑quality certificate tied to Brookfield‑Lewiston Falls relicensing.

Public Works Director Kevin Gagne said moving the Androscoggin River’s receiving standard from class C to class B would be an important environmental milestone, but he cautioned that higher receiving‑water standards would impose more stringent effluent expectations on municipal treatment plants. In staff estimates discussed during the meeting, moving to a class B receiving water could require additional treatment investments that, in a future permit cycle, might translate to a 15–20% impact on sewer rates for customers.

Director Gagne framed the council endorsement as supportive of water quality while urging residents to understand the potential downstream fiscal consequences for treatment operations. Councilors approved the letter and asked staff to circulate the signed document to DEP.

Ending: The vote signals municipal support for higher river water quality while flagging that future plant upgrades and rate implications should be part of public conversations and financial planning.
