    n. Project Description: The existing McCloud-Pit Project consists 
of three existing developments (James B. Black, Pit 6, and Pit 7), 
which collectively include two storage reservoirs (McCloud and Iron 
Canyon), two regulating reservoirs (Pit 6 and Pit 7), one afterbay (Pit 
7), two tunnels, three powerhouses (James B. Black, Pit 6, and Pit 7), 
and associated equipment and transmission facilities. The project has 
an installed capacity of 368 megawatts (MW), produces an average annual 
generation of 1,542 gigawatt-hours (GWh), and occupies 3,707.6 acres of 
land. Approximately 1,651.4 of these acres are federally owned, with 
1,621.9 managed by the Shasta-Trinity National Forest and 29.5 managed 
by the U.S. Bureau of Land Management. In addition to the existing 
facilities, PG&E is proposing to construct two generation additions 
consisting of powerhouses at the base of McCloud dam (5-8 MW) and at 
the base of Pit 7 Afterbay dam (10 MW).
    The project involves the transfer of water from the McCloud River 
basin to the Lower Pit River basin via a tunnel from the McCloud 
reservoir to Iron Canyon reservoir. Iron Canyon reservoir is on Iron 
Canyon creak, a tributary of the Pit River. Water flows from Iron 
Canyon reservoir via a tunnel to the James B. Black powerhouse. 
Although the project diverts water from the McCloud River basin to the 
Lower Pit River basin, both basins drain to Shasta Lake.

James B. Black Development

McCloud Dam and McCloud Reservoir

    McCloud dam is a 241-foot-high, 630-foot-long earth and rock filled 
dam located on the McCloud River and impounds McCloud reservoir. The 
McCloud reservoir has a surface area of 520 acres and a maximum storage 
capacity of approximately 35,234 acre-feet (af). The spillway 
[elevation 2,696.0 feet National Geodetic Vertical Datum (NGVD)] is on 
the south side of the dam. The reservoir has a normal maximum water 
surface elevation of 2,680 feet. The dam is equipped with three radial 
gates measuring 27 feet by 24.5 feet, discharging into a spillway that 
returns spillage flows to the McCloud River below the dam. The dam also 
has a 12-foot diameter diversion/outlet tunnel that runs under the dam 
to supply a 24-inch Howell-Bunger valve for releasing instream flows to 
the McCloud River, as well as an 84-inch diameter butterfly valve for 
emergency use to control reservoir levels. Controls for the

[[Page 65107]]

diversion/outlet tunnel are located at the intake within McCloud 
reservoir.

McCloud Tunnel

    A 7.2-mile-long tunnel and a 563-foot-long pipeline at Hawkins 
Creek crossing hydraulically link McCloud reservoir and Iron Canyon 
reservoir. An intake tower within McCloud reservoir collects water for 
the McCloud tunnel, which is approximately 17 feet in diameter and 
heads easterly to Iron Canyon reservoir. The differential in water 
surface elevations between the two reservoirs controls the amount of 
water drafted through the tunnel.

Iron Canyon Dam and Reservoir

    An earth-filled dam 214-feet-high and 1,130-feet-long impounds Iron 
Canyon reservoir. The reservoir has a maximum storage capacity of 
24,241 af with an approximate 500-acre surface area. The dam has a 
slide gate leading to a 48-inch diameter pipe for instream flow 
releases to Iron Canyon Creek. Normal maximum water surface elevation 
within the reservoir is 2,664 feet NGVD. When the water surface of Iron 
Canyon reservoir is lowered, water flows through the McCloud tunnel 
from McCloud reservoir to Iron Canyon reservoir.

Iron Canyon Tunnel and Penstock

    Iron Canyon reservoir is connected to James B. Black powerhouse via 
the 2.9-mile long, 18-foot diameter Iron Canyon Tunnel, an associated 
1,194-foot-long, 11.5-foot diameter pipeline at the Willow Spring Creek 
crossing, and a 5,467-foot-long, 11.5-foot diameter steel penstock. The 
penstock bifurcates before James B. Black powerhouse to deliver water 
flow to the two turbine generator units. The tunnel and penstock have a 
total flow capacity of 2,000 cfs.

James B. Black Powerhouse

    James B. Black powerhouse is located on the northwest bank of the 
Pit River, approximately 0.5 miles upstream of the Pit 5 Project 
powerhouse (FERC Project No. 233). The powerhouse is a three-level, 
reinforced concrete structure containing two vertical shaft impulse 
turbines rated at 104,000 hp each. They operate at a normal maximum 
gross head of 1,226 feet. Two vertical axis outdoor generators, Unit 1 
rated at 94.8 megavolt-ampere (MVA) and Unit 2 rated at 92.6 MVA, are 
connected to a three phase, 86 MVA transformer bank. Their combined 
maximum capacity is 172 MW. Average annual generation within the past 
25 years at the station is 656.3 GWh.

Transmission

    Transmission lines (230 kilovolt [kV]) extend approximately 0.5 
mile from the transformer bank in the switchyard adjacent to the James 
B. Black powerhouse to the switchyard adjacent to the Pit 5 powerhouse.

Pit 6 Development

Pit 6 Dam and Reservoir

    Pit 6 dam and reservoir are located on the Pit River downstream of 
James B. Black powerhouse. The 183-foot-high, 560-foot-long concrete 
gravity Pit 6 dam has a crest elevation of 1,432 feet NGVD. The top of 
the dam contains a trash rake, motors for two 42-foot-high by 49-foot-
long slide gates and a control building. The control building houses a 
hydraulic system for two low-level, eight-foot diameter outlets at the 
base of the dam. The Pit 6 reservoir has a maximum storage capacity of 
approximately 15,619 af and a maximum surface area of approximately 268 
acres. The normal maximum water surface elevation within the reservoir 
is 1,425 feet NGVD. The reservoir serves as the forebay for the Pit 6 
powerhouse. Two 18-foot diameter steel penstocks with a total flow 
capacity of 6,470 cfs extend 602 feet from the dam to the turbines in 
the powerhouse located at the base of the dam.

Pit 6 Powerhouse

    Pit 6 powerhouse is located along the east bank of the Pit River at 
the base of Pit 6 dam. The powerhouse is a four-level reinforced 
concrete structure, three levels of which are below grade. The 
structure contains two vertical shaft, Francis reaction turbines, rated 
at 53,000 hp each and operating at a normal maximum gross head of 155 
feet. There are two outdoor vertical axis generators, rated at 44 MVA 
each, with each unit connected to a three-phase 44 MVA transformer bank 
that steps up plant output to 230 kV. The maximum generator capacity is 
80 MW. Average annual generation over the last 25 years is 373.8 GWh.

Transmission

    Transmission lines extend approximately 3.3 miles from the 
switchyard adjacent to the Pit 6 powerhouse to the Applicant's 
interconnected transmission system.

Pit 7 Development

Pit 7 Dam and Reservoir

    Pit 7 dam and reservoir are located on the Pit River downstream of 
Pit 6 powerhouse. The Pit 7 dam is a 228-foot-high and 770-foot-long 
concrete gravity dam. The top of the dam contains a trash rake, motors 
for two 49-foot by 42-foot slide gates at the crest of the dam, and a 
control building. The control building houses hydraulic controls for 
two eight-foot in diameter, low-level outlets at the base of the dam. 
The Pit 7 reservoir has a maximum storage capacity of 34,611 af and a 
surface area of approximately 471 acres at a normal maximum water 
surface elevation of 1,270 feet NGVD. As with Pit 6, the Pit 7 
reservoir serves at the forebay for the Pit 7 powerhouse. Two 
penstocks, 15 feet in diameter, extend 572 feet from the dam to the 
turbines in the powerhouse, located at the base of the dam. Total flow 
capacity within the penstocks is 7,440 cfs.

Pit 7 Powerhouse

    Pit 7 powerhouse is located along the east bank of the Pit River at 
the base of Pit 7 dam. The powerhouse consists of a four-level, 
reinforced concrete structure, three levels of which are below grade. 
The powerhouse contains two vertical-shaft reaction turbines that are 
rated at 70,000 hp each and operate at a normal maximum gross head of 
205 feet. Two vertical axis generators are rated at 52.2 (Unit 2) and 
62.1 MVA (Unit 1), respectively. Their maximum combined capacity is 112 
MW. Each unit is connected to a three-phase, 58 MVA transformer bank 
that steps up plant output to 230 kV. The average annual generation 
over the last 25 years is 512 GWh.

Transmission

    Transmission lines extend approximately 3.5 miles from the 
switchyard adjacent to the Pit 7 powerhouse to the Applicant's 
interconnected transmission system.

Pit 7 Afterbay

    Pit 7 afterbay has a surface area of approximately 69 acres at a 
normal ``maximum'' water surface elevation of 1,067 feet NGVD (maximum 
water surface of Shasta Lake). The afterbay dam is a 30-foot-high, 
steel-reinforced, rock-fill structure, including a variable width 
concrete gravity weir section. Pit 7 afterbay serves to attenuate 
changes in the water flow from Pit 7 dam and powerhouse before entering 
Shasta Lake.

Proposed Facilities

McCloud Development

    PG&E proposes to construct a powerhouse located at the base of 
McCloud dam. Generation output from the proposed powerhouse would be 
connected to a new transmission line that would be routed from the 
proposed powerhouse to connect to an existing

[[Page 65108]]

substation located approximately 14 miles to the north, in the town of 
McCloud, California. McCloud Development would use water stored in 
McCloud Reservoir and released into the Lower McCloud River to meet 
instream flow requirements and no new impoundments are proposed. With a 
flow range of 150 cfs to 400 cfs, the turbine and generator set would 
have an installed capacity of about 5 to 8 MW. The proposed McCloud 
Development would have an average range of annual energy production of 
30 to 40 GWh and average monthly generation would be approximately 2.5 
to 3.3 GWh. PG&E proposes to base the final size of the unit, 
powerhouse hydraulic capacity, and average annual energy production on 
instream flow requirements included in the new project license.
    The proposed powerhouse would be positioned to the south of the 
current outlet works control building and would be a reinforced 
concrete-and-block masonry structure designed to enclose and protect 
the electro-mechanical generation equipment, withstand area snow loads, 
and prevent possible vandalism. It would be accessed via the existing 
project road that connects to Forest Road 38N11. The powerhouse would 
be equipped with a single vertical-axis Francis turbine. The turbine, 
which would have a discharge diameter of approximately 54 inches, would 
operate at about 450 revolutions per minute. The direct-coupled 
synchronous generator rating would range from 5,600 to 7,500 kW.
    The proposed transmission line route from the powerhouse would 
follow Forest Road 38N11 and then county roads to the existing 
substation approximately 14 miles north in the town of McCloud.

Pit 7 Afterbay Development

    PG&E proposes to construct at Pit 7 Afterbay Development, including 
a powerhouse located on the west side of Pit 7 Afterbay dam at the 
regulating weir. Generation output from the proposed powerhouse would 
be connected to a new transmission line that would be routed from the 
powerhouse to connect to the switchyard located approximately 1.6 miles 
to the east at Pit 7 powerhouse. The proposed facilities would have no 
meaningful storage and would operate in a run-of-the-river mode. The 
available flows for energy production would be dictated by the 
operation of the upstream Pit 7 powerhouse.
    The proposed Pit 7 Afterbay powerhouse would use water released 
upstream from Pit 7 powerhouse and dam and no new impoundments are 
proposed. The proposed powerhouse would be configured for two 
horizontal-axis synchronous generating units, each rated at 5,500 kW 
and housed in an approximately 30-foot-wide x 110-foot-long intake 
approach bay. Each of the generating bays would have a design flow of 
2,500 cfs. The upstream entrance to each intake bay would include a 
trashrack to stop large debris from entering the unit. Two radial gates 
approximately 26-foot-wide by 52-foot-high would be constructed 
upstream of the unit to regulate flow and for dewatering the turbine 
pit. A roller gate would be constructed at the downstream end of each 
bay or the tailrace to prevent backwatering during maintenance. A 
combination of ramps, walkways, and ladders would be used in each bay 
to allow for maintenance access and support the gate operator 
mechanism. A 20-foot-wide bypass flow bay, which would house a radial 
gate and operator, would be built in the first phase of construction. 
The bypass flow bay would be used to pass river flows during the second 
phase of construction and during times of non-generation. The bypass 
flow bay also would require a walkway to allow maintenance and 
operation access and support the gate operator mechanism. A new access 
road would be constructed to access the powerhouse for construction, 
operation, and maintenance. The access road would extend between 
Fenders Ferry Road and the afterbay, just west of Fenders Ferry Bridge. 
Based on a flow range of 2,500 cfs to 5,000 cfs, the 2-unit powerhouse 
would accommodate turbine and generator sets capable of an installed 
capacity of about 5 MW each for a total of 10 MW. The average monthly 
generation from this proposed powerhouse would be approximately 4.2 
GWh.
    The proposed powerhouse substation would be fenced and located on 
the ground near the control house, but above the maximum anticipated 
flood and tailwater levels. Substation equipment would include a step-
up substation to transform energy for the transmission line. Powerhouse 
controls and switchgear would be installed in a separate building 
located on the right bank of the river, positioned above the maximum 
anticipated water level and inside the substation fence. The building 
would house the required equipment for control and protection of the 
generation units and would be equipped with electric heating and 
cooling. The transmission line would be a 1.6-mile-long, 34.5-kV, 
wooden-pole line connecting the proposed powerhouse to a new 34.5- to 
230-kV transformer, positioned at or near the existing 230-kV Pit 7 
switchyard. A new 230-kV circuit breaker and disconnect switch would be 
connected by a short span to the main bus of the existing Pit 7 
switchyard.
