Thunder Bay Power Co.; Notice of Intention to Hold Project Site 
Visit

August 23, 1995.
    Thunder Bay Power Company (applicant) filed on December 30, 1991, a 
new license application to continue to operate and maintain its Thunder 
Bay and Hillman Hydro Projects located on the Thunder Bay River in 
Alpena, Alcona, and Montmorency Counties, Michigan. The applicant has 
requested that the Commission combine the two licensed projects into a 
new license.
    The Thunder Bay and Hillman Hydro Project as presently licensed

retaining wall, 6 feet high by 285 feet long; (2) an existing 
buttressed retaining wall, 145 feet long; (3) an existing abandoned 
fishway; (4) an existing concrete uncontrolled spillway section, 47 
feet long; (5) an existing gated spillway section, 131 feet long, 
containing seven tainter gates, each 14 feet long by 12 feet high; (6) 
an existing concrete gravity non-overflow section, 47 feet long; (7) an

powerhouse, 72 feet by 72 feet, containing (a) a concrete forebay, (b) 
three existing horizontal shaft Sampson runner turbines with a combined 
hydraulic capacity of 1790 cfs, rated at 850 hp each, and (c) three 
existing General Electric generators, each rated at 600 kW, providing a 
total existing plant rating of 1,800 kW; and (4) existing appurtenant 
facilities.
    Norway Point Development which includes: (1) Two existing earth 
dikes, 1,460 feet long and 500 feet long yielding a total length of 
1,960 feet; (2) an existing abandoned fishway; (3) an existing beartrap 
gate section, 120 feet long, containing three beartrap gates, each 26 
feet long by 27 feet high; (4) an existing mass concrete multiple 
barrel arch spillway section with removable needle beams, 320 feet 
long; (5) an existing reservoir with a surface area of 1,700 acres and 
a total storage volume of 27,550 acre-feet at the normal maximum 
surface elevation of 671.6 feet NGVD; (6) an existing reinforced 
concrete and masonry powerhouse, 86 feet long by 49 feet wide, 
containing (a) two vertical shaft Francis turbines with a combined 
hydraulic capacity of 1650 cfs, the first manufactured by Wellman-
Seaver-Morgan Company and rated at 3,350 hp and the second rated at 
1,400 hp, and (b) two General Electric generators, rated at 2,800 kW 
and 1,200 kW, providing a total point rating of 4,000 kW; and (7) 
existing appurtenant facilities.
    Hubbard Lake Development which includes: (1) An existing reinforced 
concrete spillway section, 20 feet long, containing two needle beam 
controlled bays; (2) two existing 45 foot long earth embankment 
sections, each overlapped on the upstream and downstream sides with 
concrete wing walls extending from both sides of the spillway; (3) an 
existing reservoir with a surface area of 9,280 acres and a total 
storage volume of 57,000 acre-feet at the normal maximum surface 
elevation of 710.5 feet NGVD; and (4) existing appurtenant facilities.
    Upper South Development which includes: (1) Two existing earth 
embankment sections, 220 feet long and 40 feet long for a total length 
of 260 feet; (2) an existing reinforced concrete spillway section, 40 
feet long, containing (a) four needle beam controlled bays, and (b) 
concrete wing walls on the upstream and downstream sides overlapping 
the earth embankments on both sides of the spillway; (3) an existing 
reservoir with a surface area of 7,000 acres and a total storage volume 
of 55,000 acre-feet at the normal maximum surface elevation of 731.0 
feet NGVD; (4) two proposed submersible Flygt Corporation turbines with 
a combined hydraulic capacity of 170 cfs, each equipped with a siphon 
penstock and an elbow draft tube; and (5) existing appurtenant 
facilities.
B. Hillman Hydro Project FERC No. 2419

    This project consists of: (1) An existing earth fill section, 
approximately 50 feet long; (2) an existing concrete gated spillway 
section, approximately 38 feet long, containing (a) three needle beam 
controlled bays, (b) a concrete training wall extending upstream of the 
spillway along the right side, and (b) a reinforced concrete apron, 
constructed along the downstream toe of the spillway; (3) an existing 
non-overflow section which includes part of the Hillman grist mill 
house, 26 feet long, constructed of upstream and downstream concrete 
gravity walls with pressure grouted earth and rock fill between the two 
walls; (4) an existing concrete uncontrolled spillway section, 27 feet 
long, (formerly the intake structure of the grist mill in the early

volume of 500 acre-feet at the normal maximum surface elevation of 
747.2 feet NGVD; (7) an existing reinforced concrete and masonry 
powerhouse, 17 feet by 21 feet, containing (a) a vertical shaft Francis 
turbine with a hydraulic capacity of 270 cfs, manufactured by James 
Leffel Company, and (b) a vertical shaft generator, manufactured by 
Westinghouse and rated at 250 kW; and (8) existing appurtenant 
facilities.
    The applicant proposes increasing capacity at the Upper South 
Development by 200 kW as well as increasing the capacity at the Four 
Mile Development by 600 kW, with the addition of three new generators, 
respectively. The applicant estimates that the proposed total installed 
project capacity would be 8.25 MW with a total average annual 
generation of 8.26 GWH. The dam and existing project facilities of each 
development are owned by the applicant. Project power would be utilized 
by the applicant for sale to its customers.

Project Site Visit

    The Commission staff will conduct a three day project site visit of 
the Thunder Bay and Hillman Hydro Projects. The site meeting will be 
held starting at 2:00 P.M. on September 5, 1995 at the entrance of the 
Hillman Development and continue the next day (on September 6, 1995) at 
8:00 A.M. at the Ninth Street Development, and finish on September 7, 
1995 with the start at 8:30 A.M. at the Fletcher Floodwater and 
conclusion at 12:30 P.M. at the Hillman Development. All interested 
individuals, organizations, and agencies are invited to attend. All 
participants are responsible for their own transportation to and from 
the project site. For more details, interested parties should contact 
Patrick Murphy, FERC, at (202) 219-2659 and Steve Naugle, FERC, at 
(202) 219-2805, prior to the site visit date.
