[Project No. 2520-098]
Great Lakes Hydro America, LLC; Notice of Availability of
Environmental Assessment
In accordance with the National Environmental Policy Act of 1969
and the Federal Energy Regulatory Commission's (Commission or FERC)
regulations, 18 CFR part 380, Commission staff reviewed Great Lakes
Hydro America, LLC's application for a temporary variance of the
license for the Mattaceunk Hydroelectric Project No. 2520 and has
prepared an Environmental Assessment (EA) for the project.\1\ The
licensee proposes to draw the impoundment down to perform repair to the
upstream fishway and log sluice at the Mattaceunk Project, replace the
sluice gate due to deterioration, and perform concrete repairs to the
leaking slots immediately downstream of the sluice gate. The fishway
maintenance work is necessary in preparation for upcoming and required
evaluations of the fishway for upstream Gulf of Maine Distinct
Population Segment of Atlantic salmon passage that begins in 2026. The
project is located on the Penobscot River, in Aroostook and Penobscot
counties, Maine and does not occupy federal land.

\1\ The unique identification number for documents relating to
this environmental review is EAXX-019-20-000-1753693860.

The EA contains Commission staff's analysis of the potential
environmental effects of the proposed temporary variance, alternatives
to the proposed action, and concludes that the temporary variance, with
appropriate environmental protective measures, would not constitute a
major federal action that would significantly affect the quality of the
human environment.
