Notice of Availability of Revised Final Engineering Guidelines 
for the Evaluation of Hydropower Projects: Chapter 16--Part 12d Program

    On December 16, 2021, the Federal Energy Regulatory Commission 
issued a Notice of Availability of Final Engineering Guidelines for the 
Evaluation of Hydropower Projects: Chapter 16--Part 12D Program.\1\ 
Chapter 16 provides licensee guidance related to any Periodic 
Inspection or Comprehensive Assessment performed, and the report on it 
filed, to fulfill the requirements defined in Title 18 Code of Federal 
Regulations (CFR) Part 12, Subpart D. The Chapter includes an overview 
of the part 12D program, as well as six appendices. Appendices B, C, D, 
and E are outlines for the four major types of reports that must be 
submitted. Due to a compilation error during final preparation of the 
chapter, four of the included appendices were from an outdated draft 
version that did not incorporate all of the changes that staff made to 
address comments received on the draft chapter. This notice provides a 
revised version of Chapter 16's appendices B, C, D, and E, which were 
the only portions of Chapter 16 that were affected by this error.
---------------------------------------------------------------------------

    \1\ Chapter 16 is one of four new chapters of the Guidelines 
providing additional guidance related to 18 CFR part 12, Safety of 
Water Power Projects and Project Works, for which a Final Rule was 
also issued on December 16, 2021. Final Rule, Order No. 880, 87 FR 
1490 (Jan. 11, 2022), 177 FERC ] 61,204 (2021).
---------------------------------------------------------------------------

    The appendices provide the outlines and instructions for several 
required filings that document a Part 12D Inspection and are required 
by the Commission's regulations: Appendix B: the Periodic Inspection 
Report (PIR), Appendix C: Periodic Inspection Pre-Inspection 
Preparation Report (PI-PIPR), Appendix D: Comprehensive Assessment 
Report (CAR), and Appendix E: Comprehensive Assessment Pre-Inspection 
Preparation Report (CA-PIPR). These revisions to Appendices B through E 
ensure that the report outlines and content are consistent with the 
corresponding text in the body of Chapter 16. The revisions in each 
appendix are described below.
