Daily Rules, Proposed Rules, and Notices of the Federal Government
On November 9, 2012, the New England Hydropower Company, LLC, filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act (FPA), proposing to study the feasibility of the Cochrane Dam Hydroelectric Project (Cochrane Dam Project or project) to be located on the Charles River, near Needham and Dover, Norfolk County, Massachusetts. The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term. A preliminary permit does not authorize the permit holder to perform any land-disturbing activities or otherwise enter upon lands or waters owned by others without the owners' express permission.
The proposed project would consist of the following: (1) An existing 15-foot-high, 200-foot-long stone masonry spillway dam with concrete retaining walls; (2) an existing impoundment with a 5.1-acre surface area and a normal storage capacity of 640 acre-feet at an operating elevation of about 102.3 feet above mean sea level (msl); (3) an existing 30-foot-long, 18-foot-wide, and 10-foot-deep head box and intake channel; (4) a new 6-foot-high, 14-foot-wide sluice gate equipped with a 14-foot-high, 21-foot-wide trashrack with 6-inch bar spacing; (5) a new 50-foot-long, 13-foot wide Archimedes screw generator unit with an installed capacity of 170 kilowatts; (6) a new 10-foot-high, 18-foot-long, 18-foot-wide powerhouse containing a new gearbox and electrical controls; (7) an existing 375-foot-long, 20-foot-wide, and 4-foot-deep tailrace; (8) a new above ground 300-foot-long, 35-kilovolt transmission line connecting the powerhouse to the NSTAR regional grid; and (9) appurtenant facilities. The estimated annual generation of the proposed Cochrane Dam Project would be about 811 megawatt-hours. The existing Cochrane Dam and appurtenant works, including a former powerhouse foundation and intake structures, are owned by the Commonwealth of Massachusetts and operated by the Massachusetts Department of Conservation and Recreation.
