    k. This application is not ready for environmental analysis at this

    l. The existing project consists of: (1) a 242-acre impoundment 
with a normal storage volume of 1,970 acre-feet and a normal headpond 
elevation of 158.76 ft (NAVD 88); (2) a rock filled concrete cap, 
variable in height dam with an approximately 132-foot-long spillway at 
a permanent crest elevation of 154.66 feet, and nominal 4.0-foot-high 
wooden flashboards maintaining a normal headpond elevation of 158.76 
feet; (3) a 22-foot-wide and 170-foot-long reinforced concrete power 
canal located between the right bank of the Nashua river and the single 
flood sluice gate; (4) two 12.5-foot-long wooden stoplog bays located 
immediately upstream of the intake to the right of the concrete capped 
spillway (viewed facing downstream) with a 10-foot-wide gate and a 
short spillway section above the gate; (5) a 40-foot-wide, 20-foot-high 
intake structure with steel trashrack with two square-to-round 
transition openings that feed the two penstocks that terminate at the 
two turbines; (6) two 64-foot-long, 104-inch-diameter steel penstocks 
between the intake and turbine units; (7) a 44-foot-long, 44-foot-wide 
multi-level reinforced concrete powerhouse containing two 1,500 
kilowatt turbine-generator units; (8) an approximately 22-foot-wide, 
1,100-foot-long tailrace that is a channel cut into the Nashua river 
bedrock downstream of the powerhouse that returns water back

[[Page 25396]]

into the Nashua river; (9) a 278-foot-long bypass reach extending from 
the spillway crest and stoplog bays to the downstream of the powerhouse 
at the tailrace, bypassing 20 cubic feet per second (cfs) of water for 
environmental flows; (10) an upstream fish passage; (11) a 610-foot-
long, 34.5-kilovolt underground transmission line connects the 
generator transformer to the interconnect point; and (12) appurtenant 
facilities. The estimated gross head of the project is 38 feet. The 
powerplant has a maximum nameplate capacity of 3 MW. The project 
generates an annual average of 12,563 megawatt-hours.
    The City proposes to continue to operate the project in a run-of-
river mode with no storage or flood control capacity. The project 
operates within a flow range of 180 cfs (150 cfs minimum hydraulic 
capacity to start a single turbine, plus 20 cfs minimum bypass release 
at the dam and an additional 10 cfs flow routed through the Mill Pond 
gatehouse to the Mill Pond and canal) and 1,100 cfs (maximum hydraulic 
capacity of the plant--two turbines combined) or a river flow of 1,130 
cfs. Any flow above the capacity of the turbines plus minimum bypass 
flow and Mill pond diversion is spilled over the dam spillway and 
through the overflow section of the flood sluice gate.

    o. Scoping Process:
    The Commission staff intends to prepare an Environmental Assessment 
(EA) for the Mine Falls Hydroelectric Project in accordance with the 
National Environmental Policy Act. The EA will consider site-specific 
environmental impacts and reasonable alternatives to the proposed 
action.
    Commission staff does not propose to conduct any on-site scoping 
meetings at this time. Instead, we are soliciting comments, 
recommendations, and information, on the Scoping Document (SD) issued 
on April 19, 2023.
    Copies of the SD outlining the subject areas to be addressed in the 
EA were distributed to the parties on the Commission's mailing list and 
the applicant's distribution list. Copies of the SD may be viewed on 
the web at http://www.ferc.gov using the ``eLibrary'' link. Follow the 
directions for accessing information in paragraph m. Based on all 
written comments, a Scoping Document 2 (SD2) may be issued. SD2 may 
include a revised schedule, as well as a list of issues, identified 
through the scoping process.

    Dated: April 19, 2023.

Deputy Secretary.
