Federal regulators are recommending only minor changes to a proposal to remove two Penobscot River dams and bypass a third as part of a historic plan to restore fish habitat throughout the watershed.
In a draft environmental assessment released this month, staff at the Federal Energy Regulatory Commission determined that the river restoration project would benefit native plants and animals as well as increase recreational opportunities in the lower Penobscot.
FERC staff with the Office of Energy Projects acknowledged the proposed removal of the Veazie and Great Works dams has the potential to affect some protected species as well as historic cultural sites. But they said those impacts should be minimized by the numerous agreements included in the Penobscot River Restoration Trust’s proposal and required consultations.
FERC is seeking public comment on the draft assessment through Sept. 3.
“Based on our evaluation of the environmental effects and public benefits of the Trust’s proposal, we conclude that approving the surrender of the Veazie, Great Works, and Howland [dams] … would be in the public interest,” FERC staff wrote in the draft environmental assessment.
Under the terms of a 2003 agreement, the power company PPL Corp. offered to sell the three dams for $25 million to the coalition of groups comprising the Penobscot River Restoration Trust. In turn, PPL was allowed to increase power generation at six other dams within its ownership. Federal officials have hailed the proposal as one of the most significant river restoration projects in the nation’s history.
With money in hand, the trust is seeking the federal approvals necessary to take ownership of the dams.
The plan calls for removing the Veazie and Great Works dams and building a state-of-the-art fish bypass around the Howland dam. All told, the changes are expected to reopen nearly 1,000 miles of river habitat to endangered Atlantic salmon, shad, alewives, eels and other species of sea-run fish.
FERC staff have recommended relatively minor changes to the proposal. Those modifications include:
— Development of erosion and sedimentation control plans prior to work on the dams.
— Implementation of a memorandum of understanding between the Trust, the Penobscot Indian Nation (a Trust member) and other partners addressing possible impacts to historic sites.
— Monitor for and clear any obstructions to fish passage into tributaries after the water level has dropped following the dams’ removals.
— Submit an invasive species monitoring and control plan to prevent invasive plants from out-competing native plants at the sites of the former impoundments.
FERC staff noted the concerns raised by some sportsmen that the proposed Howland bypass could allow upstream access to northern pike, a large fish with a voracious appetite introduced illegally into Maine waters.
The sportsmen fear that pike could harm the prized brook trout fisheries in the Piscataquis River, the East Branch of the Pleasant River and even potentially the West Branch of the Penobscot.
Pike already are present in Pushaw Lake outside of Bangor and, it is feared, may be establishing themselves in the Penobscot.
But FERC noted the state has filed a plan to continue monitoring for pike and taking steps to halt their migration. Proposals include maintaining current blockages in some locations in the headwaters and creating velocity or jump barriers at Guilford. And the report stated that a proposed “trap and sort” system at the Howland dam would in all likelihood not be feasible and would negate the intention of a quasi-natural bypass.
The draft assessment also pointed the finger back at fishermen.
“The presence of multiple dams in the Androscoggin, Kennebec, and Sebasticook watersheds has not prevented introduction of pike into headwaters in those watersheds, suggesting that humans have likely introduced northern pike above these dams,” the report reads.
Overall, FERC staff wrote that the proposed removal of the Veazie and Great Works dams “will benefit greatly” sea-run fish. The proposed fish passage upgrades at the Milford dam and the new bypass at the Howland dam “will allow these species to access their entire historic habitat in the Penobscot watershed.”
