l. The existing Cocheco Falls Dam Project consists of: (1) A 150-foot-long, 13.5-foot-high stone masonry arch dam that includes the following sections: (a) A 4-foot-long left abutment section; (b) a 140-foot-long spillway section with 24-inch-high flashboards, a 5-foot-wide, 10-foot-high low-level outlet gate, and a crest elevation of 36.25 feet National Geodetic Vertical Datum of 1929 (NGVD29) at the top of the flashboards; and (c) a 6-foot-long right abutment section with a 4-foot-wide, 9-foot-high debris sluice gate; (2) an impoundment with a surface area of 20 acres and a storage capacity of 150 acre-feet at an elevation of 36.25 feet NGVD29; (3) a 64-foot-wide, 10-foot-high intake structure equipped with a trashrack with 1-inch clear bar spacing; (4) an 8.5-foot-diameter, 184-foot-long gated steel penstock that trifurcates into three 5-foot-diameter, 8-foot-long sections, each controlled by a 5-foot-diameter butterfly valve; (5) a 40-foot-long, 40-foot-wide concrete and brick masonry powerhouse containing three 238-kW vertical Flygt submersible turbine-generator units for a total installed capacity of 714 kW; (6) a 40-foot-long, 40-foot-wide tailrace that discharges into the Cocheco River; (7) a 0.48/34.5-kilovolt (kV) step-up transformer and a 1,000-foot-long, 34.5-kV underground transmission line that connects the project to the local utility distribution system; and (8) appurtenant facilities.

CFA voluntarily operates the project in a run-of-river mode using an automatic pond level control system to regulate turbine operation, such that outflow from the project approximates inflow. The project creates an approximately 200-foot-long bypassed reach of the Cocheco River.

Downstream fish passage is provided by a bypass facility located on the left side of the dam that consist of a 5.6-foot-wide, 7-foot-long fish collection box, a trashrack with 6-inch clear bar spacing, and a 24-inch-diameter PVC fish passage pipe. Upstream fish passage is provided by a Denil fish ladder located on the right side of the dam. The Denil fish ladder is owned and maintained by the New Hampshire Fish and Game Department, and is not a project facility.

Article 25 of the current license, as amended on September 24, 2002, requires a minimum flow release to the bypassed reach of: (1) 20 cubic feet per second (cfs) through the fish ladder from April 15-June 30; (2) 20 cfs through the trash sluiceway from April 15-June 15, to attract anadromous fish to the fish ladder; and (3) 20 cfs through the downstream fish passage facility from April 15 until ice forms on the river. The average annual energy production from 2014 to 2018 was 1,438 megawatt-hours

CFA proposes to: (1) Continue to operate the project in a run-of-river mode; (2) continue to facilitate upstream and downstream fish passage by providing the minimum flows required by the current license; (3) design and install an upstream eel passage facility at the Denil fish ladder location within 4 years of the effective date of a subsequent license; and (4) consult with the New Hampshire State Historic Preservation Officer before beginning any land-disturbing activities or alterations to known historic structures within the project boundary.

o. Scoping Process.

Commission staff will prepare either an environmental assessment (EA) or an Environmental Impact Statement (EIS) that describes and evaluates the probable effects, if any, of the licensee's proposed action and alternatives. The EA or EIS will consider environmental impacts and reasonable alternatives to the proposed action. The Commission's scoping process will help determine the required level of analysis and satisfy the NEPA scoping requirements, irrespective of whether the Commission prepares an EA or an EIS. Due to concerns with large gatherings related to COVID-19, we do not intend to conduct a public scoping meeting and site visit in this case. Instead, we are soliciting written comments and suggestions on the preliminary list of issues and alternatives to be addressed in the NEPA document, as described in scoping document 1 (SD1), issued June 8, 2021.

Copies of the SD1 outlining the subject areas to be addressed in the NEPA document were distributed to the parties on the Commission's mailing list and the applicant's distribution list. Copies of SD1 may be viewed on the web at using the “eLibrary” link. Enter the docket number excluding the last three digits in the docket number field to access the document. For assistance, call 1-866-208-3676 or for TTY, (202) 502-8659.
