Re:12th Independent Consultant’s Safety Inspection Report for Little Grass Valley Dam
Dear Mr.Moseley:
This is in response to a letter dated January 27, 2023,from Ms. Kristen Mackillop that
submitted the 12th Independent Consultants’ (ICs’)Safety Inspection Report (Part 12D
report) for Little Grass Valley Dam, which is part of the South Feather Water and Power
Agency, FERC Project No. 2088. Our review of the document concludes that the scope and
content of the report satisfies the requirements of Part 12, Subpart D, §12.37 of Title 18 of
the Code of Federal Regulations.The Part 12D Report was found to be prepared in general
accordance with the Engineering Guidelines Chapter 14 and we have the following
comment:
Regarding seismicity at Little Grass Valley Dam: In the Part 12D report the ICs’
observed that, based on STID Section 5, the most recent complete deterministic
ground motions are from a 2007 report which utilizes 1997 attenuation relationships.
Note that as part of the 2012 Part 12D Reports (including Little Grass Valley Dam)
the ICs updated Section 5 of the STIDs using the Next Generation Attenuation (NGA)
2008 relationships, which superseded the referenced 2007 estimates. It is not clear
when or why those updates have been removed or lost. Explain why the 2012 updates
are no longer needed, or revise Section 5 to ensure those results are re-added.Note
that this issue should be checked for the other project STIDs (unless they have more
recent updates).
Within 30 days of the date of this letter provide a response to our comment or a plan
and schedule for doing so. File your submittal using our eFiling system at
