k. Project Description: The Ripogenus Project is located about 21 river miles upstream of the Penobscot Mills Project, and consists of: (1) the Ripogenus impoundment, which (a) is about 20.8 miles long, (b) has a surface area of about 29,270 acres at a normal full pond elevation of 941.59 feet National Geodetic Vertical Datum of 1929 (NGVD 29), and (c) has a usable storage of about 688,705 acre-feet, with a maximum drawdown of 44 feet (to elevation 897.59 feet NGVD 29); and (2) Umbazooksus Lake, which has a surface area of 1,600 acres. Ripogenus Dam is 795 feet long and is located at the outlet of Ripogenus Lake. The dam includes two concrete spillway sections, an intake section, a gated sluice section, and an earthen section.
Water flows from the Ripogenus impoundment through an intake structure, which directs water through a tunnel and penstocks to the powerhouse (McKay Station). The powerhouse contains three turbine-generating units, with a total rated capacity of 37.5 megawatts. Power generated at the project is transmitted to the electric grid via three transformers and a 29.4-mile-long transmission line. An additional 0.75-mile-long transmission line extends from the McKay Substation to Ripogenus Dam. The Ripogenus Project also contains one battery energy storage site that is used to enhance system reliability. The Ripogenus Project is operated as a store-and-release development, with an annual seasonal drawdown that allows for management of water levels and flows downstream from the project. GLHA releases minimum flows into the dewatered section of the West Branch downstream from Ripogenus Dam, as well as flows through the McKay Station generating units to protect aquatic habitat and to provide whitewater boating opportunities. GLHA also releases flows to the West Branch during outages of the generating units, and diverts flow to the Holbrook Side Channel to enhance aquatic habitat. The project provides some capacity to store water to reduce downstream flooding, as well as storage releases during droughts. Additional details regarding the Ripogenus Project facilities and operations can be found in Exhibit A (Ripogenus Project) and Exhibit B of the license application, and can be accessed by following the instructions in paragraph l.
GLHA proposes to continue to operate the Ripogenus Project as a store-and-release facility. GLHA would continue to release flows ranging between 12 cubic feet per second (cfs) and 100 cfs from Ripogenus Dam to the bypassed reach, provide a station outage flow of 400 cfs downstream from McKay Station, continue to operate and maintain the Holbrook Side Channel as habitat for salmon and brook trout, maintain the 200-foot conservation buffer and 100-foot vegetation buffer around the Ripogenus impoundment, and maintain Umbazooksus Lake as wetland and wildlife habitat. In addition, GLHA proposes to provide a year-round minimum flow of 1,700 cfs downstream from McKay Station for aquatic habitat; provide seasonally-adjusted flows for whitewater boating; fund the installation, operation, and maintenance of a USGS flow gauge downstream from McKay Station (near Big Eddy); post impoundment level and flow information on Brookfield's existing SafeWaters website; and develop a recreation plan, shoreline management plan, loon management plan, and historic properties management plan.
