Riley is the most upstream of the four developments, located at river mile 58.0. Riley dam is a 19.2 ft high by 757 ft long, L-shaped, rock-filled timber crib structure. The dam is topped with 48-inch high flashboards. A triangular forebay discharges to the six identical turbines contained in the 100-ft by 236-ft powerhouse. Turbines are horizontal shaft units, installed in 1982, each rated for 926 cfs hydraulic capacity and electrical output of 1.3 MW. Maximum available head for the turbines at Riley is 20.9 feet. Note also that the Riley forebay is the source of process water supply to the pulp and paper mill.
The Jay development is at river mile 56.5. Jay dam is totals 893 feet in length and is comprised of three non-contiguous sections separated by 2 island area. The two outer sections of Jay dam are topped with 32-inch flashboards. Jay has a 320-ft forebay leading to the 32-ft by 147-ft powerhouse. The six turbine-generators, installed in the early 1900’s, are rated for a total flow of 3,300 cfs and will provide total electrical output of 3.1 MW. Maximum available head at Jay is 14.4 feet.
The Otis development is at river mile 54.0. The dam is composed of two contiguous spillway sections totaling 577 feet in length and topped with 24-inch flashboards. A 95-ft long forebay leads to the 70-ft by 86-ft powerhouse. The powerhouse contains two turbines, each rated for 3,000 cfs at 26 feet of head, and each having generation capability of 5.2 MW. While the Otis dam is over 100 years old, the Otis powerhouse and turbines were constructed in 1984.
Livermore is at river mile 53.2 and is the furthest downstream development within the Facility. The dams is made of two contiguous spillway sections, totaling 599 feet in length and topped with 28-inch flashboards. A 185-ft wide by 594-ft long forebay leads to two separate powerhouses: (1) the (original) 88-ft by 157-ft power house containing eight identical horizontal turbines (early 1900’s vintage) with total hydraulic capacity of 3,456 cfs and eight generators with total generation capability of 7.8 MW; and (2) a newly (2004) constructed power house and vertical turbine, discharging into the rocky area at the side of the forebay, with hydraulic capacity of 450 cfs and generating capability of 1.0 MW. Gross head available at Livermore is 33.3 feet.
October 3, 2019: The Low Impact Hydropower Institute has received a complete application for Low Impact Recertification of the Androscoggin River Hydroelectric Project. LIHI is seeking public comment on this application. Specifically, we are interested in knowing whether you think the Project meets the LIHI Low Impact Certification Criteria, as revised in the 2nd Edition Handbook. Please review the program and criteria in LIHI’s revised Handbook and then review the Project’s application materials below.
Comments that are directly tied to specific LIHI criteria (flows, water quality, fish passage, etc.) will be most helpful, but all comments will be considered. Comments may be submitted to the Institute by e-mail at firstname.lastname@example.org with “Androscoggin River Project Comments” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, 329 Massachusetts Avenue, Suite 6, Lexington, MA 02420. Comments must be received on or before 5 pm Eastern time on December 3, 2019 to be considered. All comments will be posted to the web site and the applicant will have an opportunity to respond. Any response will also be posted.
June 24, 2015: Executive Director Michael J. Sale, using authority delegated from the LIHI Governing Board, has determined that the Androscoggin Hydroelectric Project (FERC Nos. P- 2375, and P-8277) continues to satisfy the LIHI Certification Criteria. The effective certification date for the Androscoggin Project is September 25, 2014 for a five (5) year term, which will expire on September 25, 2019. The Androscoggin Certification includes one project specific condition:
Satisfied 2019. Condition 1. The facility owner shall consult with the Maine Department of Environmental Protection (MDEP) on water quality issues below the dams, provide the most recently collected monitoring data for dissolved oxygen concentrations (DO) to MDEP, and determine whether additional monitoring data are needed below their Androscoggin dams. The facility owner shall provide documentation to LIHI by December 31, 2015, concerning MDEP’s conclusion on DO monitoring and conduct any new DO sampling as required by MDEP.
July 21, 2014: The Low Impact Hydropower Institute has received an application for a second term of certification of the Androscoggin Hydroelectric Project. The application materials are posted in the “Files” section below.
April 8, 2010: The Androscoggin Hydroelectric Project has been certified as low impact for a five year term, effective September 25, 2009 and expiring September 25, 2014.
September 25, 2009: Verso Androscoggin LLC has submitted an application for certification of the Androscoggin Project. Comments regarding the application may be submitted until November 25, 2009.
