Re: PG&E Grizzly Forebay Dam AccessImprovements, FERC No. 619
Dear Mr. Viscarra,
I have reviewed Pacific Gas & Electric’s (PG&E’s) request for access improvements at the
Grizzly Forebay Dam. Currently, the right side of the dam, right abutment and intake are
accessible from an unimproved access road off Grizzly Forebay Road. However, the overpour
spillway prevents walking access to the left side of the dam, therefore it can only be accessed by
boat. PG&E has identified several access and safety issues at Grizzly Forebay Dam that need to
be addressed to improve access for operations, maintenance, dam safety inspectors, and survey
personnel, which will improve overall safety at the dam.
Specifically, PG&E has requested to replace the access stairs at the right abutment groin from the
crest to the Low Level Outlet (LLO) valve platform and provide guardrails at the LLO platform;
improve the access from the left abutment upstream boat landing to the crest area; improve
access from the crest at the left abutment to the downstream toe for seepage monitoring; improve
access from the crest at the left abutment to Survey Marker 100; and provide guardrails at the
crest left of the spillway. Tools and materials will either be hand carried to the work location or
set into place via helicopter.
The proposed project area is on National Forest System lands within the Mt. Hough Ranger
District, PNF, under FERC jurisdiction within the Bucks Creek Hydroelectric Project (FERC
No.619). Grizzly Forebay is located in T24N, R5E, Section 34, MDBM. Construction would
occur between May and mid-October 2021.
PG&E has conducted due diligence environmental reviews and does not expect the proposed
activity to result in significant impacts to sensitive resources in the area. Biological and cultural
resource assessment summaries and proposed avoidance and minimization measures were
provided to the Forest Service on January 22, 2021.
Caring for the Land and Serving People Printed on Recycled Paper
Based on a review by resource specialists, I concur with PG&E’s request for the proposed
Grizzly Dam access improvements. As a condition of my concurrence, PG&E shall consider the
following information to protect resources.
Wildlife:
Although Sierra Nevada yellow-legged frogs do not use this reservoir and the planned
mitigations (survey and protect occupied locations, avoid impacting suitable habitat) for
amphibians will sufficiently protect SNYLF, no take of frogs is allowed.
PG&E will complete planned spotted owl surveysas proposed and share results with the
USFS biologist.
One goshawk nest site would likely be disturbed, but no additional recommendations
above the protection measures for birds is recommended. PG&E will complete
preconstruction goshawk surveys as planned and determine appropriate avoidance
buffers, including for helicopter use. PG&E will follow all planned protection measures
for birds outlilned in the Final 011621 Grizzly Dam Access Project Description. PG&E
shall share survey results of goshawk nest sites with the USFS biologist.
Botany:
All off road and construction equipment must be clean prior to entering NFS lands. On
page 20 of 27 of the project description it states, “Off-road equipment from outside of the
watershed will be washed and visually inspected prior to transport to the construction
area so that they are clean of dirt, mud, seeds or other plant material.” All equipment,
whether within or outside of the watershed, shall be cleaned to prevent the spread of
weeds.
Cultural Resources:
SHPO has concurred with the finding of No Adverse Effect to the historic property, letter
dated 03/12/2021.
The Forest Service appreciates PG&E’s efforts to submit adequate maps and information for this
Project. Please contact Public Service Staff Officer, Leslie Edlund at 530-283-7620 or at
leslie.edlund@usda.gov if you have any questions regarding this project.
