Subject: Part 12D Inspection Plan and IC Team Proposal, 2026 Periodic Inspection, Sly
Creek Development
Dear Mr. Moseley:
This letter is to acknowledge your November 6, 2025, letter transmitting the Part
12D Inspection Plan and Independent Consultant Team (IC Team) proposal (collectively,
the Inspection Plan) for the 2026 Periodic Inspection (PI) of Sly Creek Development of
South Feather Power Project, FERC No. 2088. We have reviewed the Inspection Plan and
have the following comments that require additional detail to fulfill the expectations as
outlined in Chapter 16 of the Commission’s Engineering Guidelines for the Evaluation of
Hydropower Projects (Guidelines):
1. The Inspection Plan states “[t]he Obermeyer Hydro Inc. pneumatically-operated,
inflatable rubber bladders will be operated and observed by the IC during the
inspection if reservoir operational conditions permit” but provides no details on
what conditions would not permit operation or the IC Team’s contingency plan to
observe test operations at a different time, if needed. As discussed in Section 16-
5.3.1 of our Guidelines, any circumstances that would prevent the IC Team from
observing these operations must be clearly described in the Part 12D Inspection
Plan for review and evaluation by the FERC. Also, if necessary, the licensee must
propose an alternate scope that accomplishes the same goal, and the FERC
reserves the option to deny the alternate scope and require that the IC Team
observe the procedures as described above. Revise the Inspection Plan to provide
the necessary information for our review.

2. The Inspection Plan did not provide sufficiently detailed information for
hydrologic and seismic loading. The Inspection Plan must state the estimated
magnitude and recurrence intervals both for seismic and hydrologic loadings as
currently understood. However, based on our understanding of the hydrologic and
seismic loading at this project, we do not believe that this information would
change the appropriate technical disciplines or levels of expertise for this PI.
Therefore, the revised Inspection Plan is not required to address this issue, but
ensure that future Inspection Plans provide all of the information requested in
Section 16-3.3 of the Guidelines. If probabilistic loading estimates for the project
have not yet been completed, it can be acceptable for the Inspection Plan to cite
the current site-specific PGA and the USGS estimates for PGAs for the 475-, 975-,
and 2,475-year recurrence intervals for comparison purposes (and similar
comparative information for hydrologic loading).
The resume for Mr. Craig Hall demonstrates that he fulfills the requirements of 18
CFR § 12.31(a), has the appropriate experience and expertise for the project features and
type of inspection, and he is accepted to serve in the role as IC for this project.
Per 18 CFR § 12.34(a), you are required to obtain the approval of the IC Team and the
Inspection Plan from the Director, Division of Dam Safety and Inspections, prior to the
performance of this PI. At this time, we are unable to provide approval of the IC Team and
the Inspection Plan pending resolution of comment 1 above.
Within 30 days of the date of this letter, provide a revised Inspection Plan that
addresses comment 1 above. File your submittal using the Commission’s eFiling system
at https://www.ferc.gov/ferc-online/overview. During eFiling make the following menu
selections: Hydro: Dam Safety; Washington, DC; Independent Consultant Approval
Request. The cover page of the filing must indicate that the material was eFiled. For
assistance with eFiling, contact FERC Online Support at FERCOnlineSupport@ferc.gov,

Thank you for your continued cooperation and interest in dam safety. If you have
any questions, please contact me at (202) 502-8486 or yilak.desta@ferc.gov.
Sincerely,
Yilak Desta, P.E.
