FEDERAL ENERGY REGULATORY COMMISSION Office of Energy Projects Division of Dam Safety and Inspections – San Francisco Regional Office 100 First Street, Suite 2300 San Francisco, CA 94105-3084 (415) 369-3300 May 15, 2024 In reply refer to: Project No. 619-CA VIA FERC SERVICE Mr. Russell Cruzen, P.E., Director Power Generation, Asset Excellence Pacific Gas and Electric Company 300 Lakeside Dr. Oakland, CA 94612-3534 Subject: 12th Part 12D Report , for a Comprehensive Assessment of the Grizzly Forebay
Dam, is due by November 1, 2025 Dear Mr. Cruzen: This letter is to inform you that the 12th Part 12D Independent Consultant’s Safety
Inspection Report (Part 12D Report) for the Grizzly Forebay Dam , part of the Bucks Creek Hydroelectric Project, FERC No. 619-04-01, is due to be submitted to this office b y
November 1, 2025. This letter contains important information about the required scope and
contents of the Part 12D Reports and reflects changes to the Commission’s
regulations that were implemented by Order 880 and went into effect on April 11,
2022. We encourage you to rea d this letter in its entirety, as well as the regulations
and associated Guidelines. General Requirements Code of Federal Regulations (CFR) Title 18, Part 12, Subpart D establishes the
Commission’s Independent Consultant (IC) Inspection Program, also referred to as the Part
12D Program, and prescribes the scope of inspections, reports, qualifications of
Independent Consultant Team (IC Team) personnel, and related procedures.1 The Part 12D
Program is implemented by the Commission’s Office of Energy Projects, Division of Dam
Safety and Inspections (D2SI). Chapter 16 of the Commission’s Engineering Guidelines 1 https://www.ecfr.gov/on/2022-04-11/title-18/chapter-I/subchapter-B/part-12/subpart-D Document Accession #: 20240515-3087 Filed Date: 05/15/2024
2 for the Evaluation of Hydropower Projects (Engineering Guidelines) provides additional
information related to the Part 12D Program.2 The list below shows several key components and deliverables that are required for
this inspection: • For the 12th Part 12D Inspections, the IC Team must perform a Comprehensive
Assessment (CA) as defined in 18 CFR § 12.31(f) and described in
18 CFR § 12.37. o The scope of a CA includes a Potential Failure Modes Analysis (PFMA)
conducted in accordance with the guidance in Chapter 17 of the
Engineering Guidelines.3 o The scope of the CA also includes a Level 2 Risk Analysis (L2 RA)
conducted in accordance with Chapter 18 of the Engineering Guidelines.4 • You must provide a Part 12D Inspection Plan in advance, including an IC Team
Proposal, and obtain written approval from the Director, D2SI in advance of the
Part 12D Inspection, as described in 18 CFR § 12.34. • The IC Team must prepare a preliminary report, referred to as a CA-Pre-Inspection
Preparation Report (CA-PIPR). The CA-PIPR must be submitted at least 30 days
in advance of the first IC Team activity, as described in 18 CFR § 12.42. Appendix
16-E of the Engineering Guidelines provides an outline for the CA-PIPR. • The IC Team must document their findings in a final Part 12D Report, specifically
a Comprehensive Assessment Report (CAR), which is described in
18 CFR § 12.38 . The CA R must be submitted by November 1, 2025 . Appendix 16-D of the Engineering Guidelines provides a n outline for the CAR. • The IC Team is to present their findings to Licensee and Commission staff during
a CA Review Meeting , as described in Section 16-7.5 of the Engineering
Guidelines. • You must provide a plan and schedule for corrective measures to address the IC
Team’s recommendations, as required by 18 CFR § 12.41 and further described in
Section 16-7 of the Engineering Guidelines. Project Development(s) Requiring Inspection The applicability of 18 CFR Part 12, Subpart D is based on project developments as
defined in 18 CFR 12.3(b)(7). A project development comprises “an impoundment and its
associated dams, forebays, water conveyance facilities, power plants, and other 2 https://elibrary.ferc.gov/eLibrary/filelist?accession_number=20211216-3085 3 https://elibrary.ferc.gov/eLibrary/filelist?accession_number=20211216-3086 4 https://elibrary.ferc.gov/eLibrary/filelist?accession_number=20211216-3088 Document Accession #: 20240515-3087 Filed Date: 05/15/2024
3 appurtenant facilities.” For this CA , the following project development requires inspection and unique reports: • Grizzly Forebay Dam Timeline of Activities The table below shows the timing of some major milestones in the CA process.
Shortly after issuance of this letter, Commission staff will contact you to schedule the initial
coordination call; Enclosure 1 provides an agenda for that call. Milestone Timing Initial Coordination Call (Licensee and FERC) Within approximately 30 days of the date of
this letter Submit the Part 12D Inspection Plan to

the IC Team’s recommendations Within 60 days after the CAR is submitted Approval of the Independent Consultant Team and the Part 12D Inspection Plan You are required to submit a Part 12D Inspection Plan at least 180 days in advance
of the first IC Team activity; since you are to perform a Comprehensive Assessment, the
first activity may be either the site inspection or PFMA/L2RA.5 The Part 12D Inspect ion
Plan must describe the scope and schedule of the inspection activities and include an IC
Team Proposal, which must: • Identify the required technical disciplines for IC(s) and supporting team members; • Identify the proposed IC(s) and demonstrate that the y meet the requirements of
18 CFR § 12.31(a); • Identify any facilitator(s) for the PFMA and L2RA; 5 18 CFR § 12.34(b) Document Accession #: 20240515-3087 Filed Date: 05/15/2024
4 • Demonstrate that the IC Team collectively has the required “experience and
expertise with dam design, construction, and in the evaluation and assessment of the
safety of existing dams, commensurate with the scale, complexity, and relevant
technical disciplines of the project and type of review, inspection, and assessment
being performed;”6 and • Address any potential conflicts of interest that ma y exist, specifically in regard to
the requirement in 18 CFR § 12.34(b)(3), which prohibits any member of the IC
Team from reviewing their own previous work. You are required to obtain written approval of the proposed IC Team from the
Director, D2SI prior to the performance of the Part 12D Inspection.7 File the Part 12D
Inspection Plan, including the IC Team Proposal, using the Commission’s eFiling system
with the following address block on your transmittal letter: Mr. David Capka, P.E., Director Division of Dam Safety and Inspections Federal Energy Regulatory Commission Office of Energy Projects You can access our eFiling system at https://www.ferc.gov/ferc-online/overview. During eFiling make the following menu selections: Hydro: Dam Safety; Washington, DC;
and Independent Consultant Approval Request. The cover page of the filing must indicate
tha t the material was eFiled. For assistance with eFiling, contact FERC Online Support at
FERCOnlineSupport@ferc.gov , (866) 208-3676 (toll free), or (202) 502-8659 (TTY). Sec tion 16-3.3 of the Engineering Guidelines provides additional information
related to the Part 12D Inspection Plan and IC Team Proposal. Please note that you may
provide the name(s) and resume(s) of any supporting members of the IC Team in the Pre-Inspection Preparation Report (discussed below) instead of the IC Team Proposal , which
provides flexibility for assigning subject matter experts closer to the inspection.8 Review of Prior Reports The IC Team must “review and consider all relevant reports on the safety of the
development made by or written under the direction of Federal or state agencies, submitted
under Commission regulations, or made by other consultants,” and “must perform
sufficient review to have, at the time of the [inspection], a full under standing of the design,
construction, performance, condition, downstream hazard, monitoring, operation, and
potential failure modes of the project works.” As the licensee, you are responsible for
“[providing] to the independent consultant team all information and reports necessary” to 6 18 CFR § 12.31(b) 7 18 CFR § 12.34(a) 8 18 CFR § 12.34(b)(4) Document Accession #: 20240515-3087 Filed Date: 05/15/2024
5 fulfill these requirements. For a CA, the IC Team must also possess an understanding of
the risk associated with the project works, though this requirement will be minimal for an
initial CA unless prior risk studies have been performed for the project. When determining whether a completed study requires review by the IC Team, the
status of the FERC review is irrelevant. The IC Team must review all current completed
studies (i.e., those have been or are ready to be submitted to the FERC and have not been
superseded). The IC Team may be requested to review in-progress studies (i.e., those that
have not been submitted to the FERC) on a case-by-case basis. Generally, the IC Team will
only be required to review studies completed by the date of FERC approval of the IC Team. Pre-Inspection Preparation Report At least 30 days p rior to the first in-person IC Team activity (field inspection,
PFMA, or RA), you are required to submit a preliminary report (the CA-PIPR)
documenting the initial findings from the IC Team’s review of project documentation,
instrumentation data, and other information.9 We will review the CA-PIPR to evaluate
whether the IC Team has an adequate understanding of project features and determine whether the inspection activities can proceed as scheduled. If the name(s) and resume(s) of
any supporting members of the IC Team were not provided in the Part 12D Inspection Plan ,
they must be provided in the letter transmitting the CA-PIPR. Section 16-4 o f the
Engineering Guidelines contains additional information regarding PIPRs. If you do not submit the CA-PIPR in a timely manner , or if the CA-PIPR does
not clearly demonstrate that the IC Team has performed the necessary level of
preparation, we may require postponement of the in-person IC Team inspection
activities. Regional Office staff will review the CA-PIPR and determine whether it is
acceptable, generally acceptable, or unacceptable, as described in Section 16-4.1 of the
Engineering Guidelines. If the CA-PIPR is acceptable or generally acceptable, the Part 12D
Inspection may proceed as scheduled, though we may request follow-up action(s) to be completed prior to the first activity. If the CA-PIPR is unacceptable, the Part 12D
Inspection will be postponed , and that postponement will not constitute good cause for an
extension to submit the CAR . If the Regional Engi neer does not issue a letter within two
weeks after the CA-PIPR is submitted, the CA-PIPR will be deemed acceptable by default. Field Inspection The scope of any Part 12D Inspection includes “a physical field inspection of
accessible project works , including galleries, adits, vaults, conduits, earthen and concrete-lined spillway chutes, the exterior of water conveyances, and other non-submerged project
features that may require specialized access to facilitate inspection.” Section 16-6.7.1 of
the Engineering Guidelines contains additional details regarding inspection of the reservoir 9 18 CFR § 12.40(f) Document Accession #: 20240515-3087 Filed Date: 05/15/2024
6 rim and spillway chutes; observation of gate operations; and the review of special
inspection reports; and the inspection of typically inaccessible features. You must provide a schedule for the field inspection to the Regional Office in
advance of the inspection. If the IC Team intends to split into smaller groups to inspect
multiple project features simultaneously, you must inform us well in advance. Typically, Regional Office staff will accompany the IC Team during the field inspection, and we will
need to ensure that we send sufficient personnel to observe the project features with the IC
Team. Any special access procedures and safety equipment should be ident ified ahead of
time so that everyone attending the field inspection can prepare accordingly. Potential Failure Modes Analysis You are required to perform a completely new Potential Failure Modes Analysis
(PFMA) as part of this Comprehensive Assessment10. Chapter 17 of the Engineering
Guidelines contains additional information about the PFMA process and requirements for
performance, documentation, and follow-up, and you should review the chapter in detail
to have a complete understanding of the process. Sections 16-6.6.2 and 16-6.6.4 of the
Engineering Guidelines provide information that is specific to the performance and
documentation of a PFMA during a CA, which is significantly different from the “PFMA
reviews” that were performed under the previous Guidelines. Please note the following significant changes to our PFMA process: • The definition of the term ‘failure’ has been revised to include not only the loss of
the reservoir, but also the inability of the project features or components to
perform their intended function and the project features or components performing
in an impaired or compromised fashion. This includes misoperation of project
elements. • Prior to identifying project potential failure modes, the PFMA team must develop
a complete understanding of the physical project features, components, and
elements and the interactions, relationships, and dependencies of those physical
elements in a systems context. This understanding must include the identification
of potential backup systems and redundancies as well as operational protocols,
stand ard operating procedures, lines of communication, feedback, and authorities
and responsibilities of project personnel. • The brainstorming session should be performed in a structured manner through
proje ct features, loading conditions, and failure mechanisms to help ensure that the
team does not miss or overlook candidate PFMs (Section 17-4.7.5 of the
Engineering Guidelines). • The PFMA must include consideration of the potential contribution and influence
of human and organizational factors, such as organizational culture and decision- 10 18 CFR § 12.37(f) Document Accession #: 20240515-3087 Filed Date: 05/15/2024
7 making authority and practices, and how these factors can contribute to failure.
The propensity toward failure is determined by the balance of factors that
contribute to failure versus safety. • When classifying candidate Potential Failure Modes (PFMs), you should use the
PFM screening process described in Chapter 17 of the Engineering Guidelines
(Section 17-4.7.8 and Figure 17-1). The Commission no longer uses numbered
categories. • PFMs should be documented in a consistent format. Appendix 17-G in the
Engineering Guidelines provides a suggested PFM template. The PFM labels
should be logical and provide an indication of what the PFM covers; Table 17-1
shows an example of a preferred nomenclature. • Licensee staff are prohibited from serving as the facilitator (Section 17-4.3.2 of the
Engineering Guidelines). Level 2 Risk Analysis (L2RA) You are required to perform a risk analysis as part of this Comprehensive
Assessment.11 Chapter 18 of the Engineering Guidelines contains additional information
about the risk analysis process and requirements for performance, documentation, and
follow-up, and you should review the chapter in detail to have a complete understanding
of the process. Sections 16-6.6.3 and 16-6.6.4 of the Engineering Guidelines provide
information that is specific to the performance and documentation of an L2RA during a
CA. Please note the following highlighted items regarding the L2RA process: • Section 18-5 of the Engineering Guidelines identifies the qualifications of the risk
analysis team, including those of the risk analysis facilitator. • The following risk measures should be included in the risk analysis: o Societal incremental life safety risk o Non-breach life safety risk o Annual probability of failure Where appropriate, economic and other consequences such as environmental,
cultural, etc. should also be considered. • Probabilistic loading estimates for hydrologic and seismic loads are required to
perform the risk analysis. These estimates must be prepared in advance of the risk
analysis session so that information is available for the risk analysis. • Likewise, consequence estimates (life loss and others as appropriate) are required
to perform the risk analysis. These estimates must be prepared in advance of the
risk analysis session so that information is available for the risk analysis. 11 18 CFR § 12.37(g) Document Accession #: 20240515-3087 Filed Date: 05/15/2024
8 • Screening of potential failure modes for the risk analysis should be performed in
accordance with the process described in Section 18-7.2 of the Engineering
Guidelines. • Risk estimates should be portrayed using the risk matrices provided in Section 18-11 of the Engineering Guidelines. • Similar to the development and documentation of potential failure modes for the
PFMA, potential failure modes for the risk analysis should be documented in a
consistent format. Appendix 18-C of the Engineering Guidelines provides a
suggested template. Comprehensive Assessment Report By the due date shown above, you are to submit the IC Team’s CAR to this office. Section 16-6 of the Engineering Guidelines contains additional information about the
documentation required in each section of the PIR. Please note the following specific
requirements that are important for you and the IC Team to fully understand: • Incorporation by Reference. The regulations implemented by Order 122 (January
28, 1981) permitted the incorporation by specific reference to a previous Part 12D
Report if the conditi ons, assumptions, and available information had not changed. This is not permitted under the regulations that were implemented by Order
880 and which went into effect on April 11, 2022. The IC Team must document
their own interpretation and evaluation in each section of the CAR , where required. • Evaluation of Performance. The evaluation of the performance of project works must be an independent interpretation based on the IC Team’s visual observations and review of instrumentation data and surveillance reports. The IC Team may not
rely entirely on previous interpretations or state that a particular condition or
instrumentation data does not indicate a potential issue simply because it is not
changing over time. The evaluation must clearly address the identified PFMs as
well as whether any previously unidentified PFMs may be active or developing. • Specific Evaluation. The IC Team must evaluate the adequacy of spillways, as
described in 18 CFR § 12.39; the structural adequacy and stability of structures
under all credible loading conditions; the potential for internal erosion and/or
piping of embankments, foundations, and abutments. 12 • Review of Design Basis and Construction. The IC Team must review historical
construction documents in order to evaluate “the design and construction practices
used during original construction and subsequent modifications, in comparison 12 18 CFR § 12.38(b)(1) through (3) Document Accession #: 20240515-3087 Filed Date: 05/15/2024
9 with the industry best practices in use at the time of the [CA].”13 Additional
information is provided in Section 16-6.3 of the Engineering Guidelines. • Review of Analyses of Record. The IC Team must review and evaluate the studies
and analyses of record and specifically address the accuracy, relevance, and
consistency with the current state-of-the-practice of dam engineering. Additional
information regarding this component of a CA is provided in Section 16-6.4 of the
Engineering Guidelines. If the IC Team is unable to review any particular analysis
of record; or if they disagree with the assumptions, methods, calculations, results,
or conclusions; the IC Team must recommend that the Licensee complete a new
analysis.14 • Recommendations . For each corrective measure the IC Team provides in the PIR ,
they are also required to provide their recommendation of a reasonable time for the
Licensee to carry out the corrective measure. Review Meeting and Presentation Within 60 days of submitting the Part 12D Report, the IC Team is to present a
summary of their findings, conclusions, and recommendations to the Licensee and
Commission staff in a CA Review Meeting. The draft review meeting presentation
should be provided to all participants in advance. The meeting may be in person, virtual,
or hybrid. Refer to Section 16-7.5 of the Engineering Guidelines for additional
information related to the review meeting. It may be helpful to conduct this meeting
between 30-45 days after submittal of the Part 12D Report so the Licensee can ask
questions before submitting their plan and schedule to address the IC Team’s
recommendations. Corrective Measures – IC Team Recommendations and Licensee Plan and Schedule Within 60 days of submitting the Part 12D Report , you must submit your plan and
schedule for addressing any recommendations provided by the IC Team.15 Your plan may
include any proposal, including taking no action, that you consider a preferred alternative to any corrective measures recommended by the IC Team , and you may not concur with
the IC Team’s recommended time to complete each corrective measure. However, it is
your responsibility to provide complete justification in support of your preferred
alternative, and the Regional Engineer may require modifications to your proposed plan
and schedule.16 You must submit an annual report documenting the status of the corrective
measures until all have been completed.17 13 18 CFR § 12.38(b)(4) 14 18 CFR § 12.38(c), § 12.36(d)(2) 15 18 CFR § 12.41(a)(1)(i) 16 18 CFR § 12.4(b)(2)(iii)(C) 17 18 CFR § 12.41(a)(2) Document Accession #: 20240515-3087 Filed Date: 05/15/2024
10 If during the course of their inspection, the IC Team discovers any condition for
which emergency corrective measures are advisable, the IC Team must notify you
immediately and you must notify the Regional Engineer pursuant to 18 CFR § 12.10(a).18 Closing The Commission’s dam safety program is a cooperative process that includes the
Licensee, the IC Team, and the FERC. The most important of the three elements is the
Licensee, as you operate the project, see the project on a regular basis, and are
responsible for the performance monitoring program used to determine if any potential
failure modes are developing. It is your responsibility as the Licensee to submit the Part
12D Report to the FERC and ensure that the Part 12D Report meets the requirements of
the Commission’s Regulations and the Engineering Guidelines before it is submitted. The
Part 12D Report is a FERC requirement but is also a valuable resource for you as the dam
owner. Except for the Part 12D Inspection Plan, which is discussed above, file the
Part 12D Report and other related submittals using the Commission’s eFiling system at https://www.ferc.gov/ferc-online/overview. When eFiling, select Hydro: Dam Safety and
San Francisco Regi onal Office. If you are also filing an STID and Digital Project Archive
(DPA), both the STID and DPA must be eFiled by selecting Hydro: Dam Safety and San
Francisco Regional Office. You must also submit one hard copy of the STID to this
office. Both the electronic and hard copy must be entire copies of the STID, do not send
individual pages or sections. If the DPA cannot be eFiled, contact the project engineer to
discuss options for transmitting the DPA to the Commission. For more information on
transmitting the DPA, see Chapter 15 of the Engineering Guidelines here:
https://www.ferc.gov/industries-data/hydropower/dam-safety-and-inspections/eng-guidelines. T he cover page of the filing must indicate that the material was eFiled. For
