k. This application has been accepted and is ready for environmental analysis at this time.

The Council on Environmental Quality (CEQ) issued a final rule on July 15, 2020, revising the regulations under 40 CFR parts 1500-1518 that federal agencies use to implement the National Environmental Policy Act (NEPA) (see Update to the Regulations Implementing the Procedural Provisions of the National Environmental Policy Act, 85 FR 43,304). The Final Rule became effective on and applies to any NEPA process begun after September 14, 2020. An agency may also apply the regulations to ongoing activities and environmental documents begun before September 14, 2020, which includes the proposed Lower Great Falls Hydroelectric Project relicensing. Commission staff intends to conduct its NEPA review in accordance with CEQ's new regulations.

l. Project Description: The existing Lower Great Falls Hydroelectric Project consists of: (1) A 297-foot-long, 32-foot-high stone masonry and concrete dam that includes the following sections: (a) a 176-foot-long spillway section with a crest elevation of 102.37 feet National Geodetic Vertical Datum of 1929 (NGVD) and 4-foot-high flashboards at an elevation of 106.37 feet NGVD at the top of the flashboards; (b) a 50-foot-long left abutment section with two 8-foot-wide, 8-foot-high low-level outlet gates (only one of which is operational), that control flow into two 7-foot-diameter, 40-foot-long outlet pipes; and (c) a 71-foot-long right abutment section; (2) a 40-acre impoundment with a normal elevation of 106.37 feet NGVD; (3) a 40.5-foot-wide, 20-foot-high intake structure with four 5-foot-wide, 10.5-foot-high steel frame gates and a trashrack with 2-inch bar spacing; (4) an 8.5-foot-diameter, 120-foot-long steel penstock that bifurcates into a 5.3-foot-diameter, 85-foot-long section and a 7.6-foot-diameter, 85-foot-long section; (5) an 8.5-foot-diameter, 140-foot-long steel penstock that bifurcates into a 7-foot-diameter, 85-foot-long section and a 7.6-foot-diameter, 85-foot-long section; (6) a 46-foot-long, 30-foot-wide concrete and brick powerhouse with two 260-kilowatt (kW) F-type Francis turbine-generator units and two 380-kW F-type Francis turbine-generator units, for a total installed capacity of 1.28 megawatts; (7) a 55-foot-long, 30-foot-wide tailrace; (8) a 260-foot-long underground transmission line that delivers power to a 4.16-kilovolt distribution line; and (9) appurtenant facilities. The project creates a 250-foot-long bypassed reach of the Salmon Falls River between the dam and the downstream end of the tailrace.

The project operates as a run-of-river (ROR) facility with no storage or flood control capacity. The project impoundment is maintained at a flashboard crest elevation of 106.37 feet NGVD. The current license requires the project to maintain a continuous minimum flow of 6.05 cubic feet per second (cfs) or inflow, whichever is less, to the bypassed reach for the purpose of protecting and enhancing aquatic resources in the Salmon Falls River. The average annual generation production of the project was 3,916,825 kilowatt-hours from 2005 through 2018.

The applicant proposes to: (1) Continue operating the project in a ROR mode; (2) provide a minimum flow of 30 cfs or inflow, whichever is less, to the bypassed reach; (3) install an eel ramp for upstream eel passage at the project; (4) implement targeted nighttime turbine shutdowns to protect eels during downstream passage; and (5) install a downstream fish passage structure for eels and other fish species.
