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
consists of the following:
A. Thunder Bay Hydro Project FERC No. 2404
This project consists of the following five developments:

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
existing reinforced concrete non-overflow section (a retaining wall
about 20 feet long); (8) an existing reservoir with a surface area of
700 acres and a total storage volume of 6,000 acre-feet at the normal
maximum surface elevation of 598.5 feet NGVD; (9) an existing
reinforced concrete and masonry powerhouse, 92 feet long by 84 feet
wide, containing (a) three horizontal shaft Sampson runner turbines
with a combined hydraulic capacity of 1620 cfs, manufactured by James
Leffel Company and rated at 600 hp each, and (b) three General Electric
generators, each rated at 400 kW, providing a total plant rating of
1,200 kW; and (10) existing appurtenant facilities.
[[Page 44865]]
The Four Mile Development which includes: (1) An existing concrete
ogee spillway (constructed immediately downstream from the original
rock filled timber dam), 445 feet long, topped by needle beams,
containing (a) a log chute bay, and (b) an abandoned fishway bay; (2)
an existing reservoir with a surface area of 90 acres and a total
storage capacity of 900 acre-feet at the normal maximum surface
elevation of 634.9 feet NGVD; (3) an existing concrete and masonry
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
1900's); (5) an existing non-overflow section, 20 feet long,
constructed of upstream and downstream concrete gravity walls with
pressure grouted earth and rock fill between the two walls; (6) an
existing reservoir with a surface area of 160 acres and a total storage
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.
