Re: Revised Drilling Program Plan for Philbrook Dam
Dear Mr. Nimick:
This is in response to letters dated February 18, 2022 and May 26, 2022 from
Mr. Robert Ellis that collectively submitted a revised Drilling Program Plan (DPP) for
Philbrook Dam, which is part of the DeSabla-Centerville Project, FERC No. 803.
submittals and have the following comments:
1. The revised DPP generally addresses our previous review comments. Subject
to Comments No. 2 through 6 below, PG&E is authorized to proceed with the
proposed drilling program.
2. We have remaining concerns about the drilling methods and approach being
proposed in relation to the resulting quality of information that will be obtained
for the intended use of the results. This was not fully addressed in the DPP and
we acknowledge that this is a challenging aspect of this project. In the final
report of the drilling results, please address the quality of information obtained
during the drilling program and how it will be used in subsequent analyses to
account for any less than favorable results.
3. The résumés for two of the proposed drillers (Paul Britton and Nick Maher) are
not acceptable. Their résumés do not indicate that they possess the requisite
embankment dam drilling experience needed for this project. Please provide
additional information demonstrating that they meet the experience
2
requirements set forth in our drilling guidelines, or else propose different
drilling personnel. Alternatively, Tom Scott can be used to perform the mud
rotary drilling on this project in addition to the sonic drilling. The résumés of
the proposed geologist (Zach Washburn, William Roman, Jeremy Robinson
and Richard Harlan) supervising the drilling work are acceptable. If any other
individuals will be used to perform or supervise the drilling work besides those
listed above, please submit their résumés for our review and authorization prior
to them beginning work on site. PG&E is reminded that résumés for proposed
project personnel must include specific project experience which is relevant to
the kind(s) of work being proposed.
4. In the emergency notification call list in Section 8.0 of the revised DPP, please
replace former FERC Branch Chief John Onderdonk with current FERC
Branch Chief Wes Cooley, as follows:
Wes Cooley, (415) 369-3340 (Office)
Branch Chief (408) 480-5024 (Cell)
5. Please keep the current FERC project engineer, Mr. Michael Vail of this office,
informed on the schedule and progress of the drilling work. Additionally,
PG&E is reminded that any conditions observed during the drilling which
could be an indication of a potential dam safety concern must be immediately
reported to the Regional Engineer.
6.
submit a geotechnical investigation report summarizing the results of the
drilling by April 30, 2022. While we understand that this schedule was based
on the assumption that the drilling would take place in 2021 rather than in
2022, this date has now passed without any extension of time requests for this
item being received by our office. Accordingly, please provide an updated
plan and schedule for submitting the geotechnical investigation report.
Additionally, if the drilling being completed in 2022 rather than 2021 will
impact any other upcoming submittal dates such as the revised stability
analysis or Supporting Technical Information Document (STID) update (due
May 28, 2021 letter), then please submit an extension of time request for these
items as well, along with appropriate supporting justification.
Within 45 days of the date of this letter, please provide the updated plan and
schedule requested in Comment No. 6 above. Comment No. 2 should be addressed in the
final drilling report, thus, a formal response to this comment is not required at this time.
Comments No. 3 through 5 should be addressed during the drilling, and a formal
3
response to those comments is not required unless different project personnel will be used
as noted in Comment No. 3. F
