[Docket No. AD18-6-000]


Notice of Availability of Revised Final Engineering Guidelines 
for the Evaluation of Hydropower Projects: Chapter 11--Arch Dams

    On March 14, 2018, the Federal Energy Regulatory Commission issued 
a Notice of Availability of Final Engineering Guidelines for the 
Evaluation of Hydropower Projects: Chapter 11--Arch Dams. Appendix 11A 
provides an approach to estimate erosion of rock downstream of arch 
dams and is applicable to similar evaluations at other types of dams. 
Commission staff recently became aware of errors in several equations 
and one table in Appendix 11A; this notice provides a revised version 
of Chapter 11 correcting those errors.
    All information related to ``Chapter 11--Arch Dams,'' including the 
draft chapter, all submitted comments, the final chapter, and the 
revised final chapter incorporating the revisions to Appendix A, can be 
found on the FERC website (www.ferc.gov) using the eLibrary link. Click 
on the eLibrary link, click on ``General Search'' and enter the docket 
number, excluding the last three digits in the Docket Number field 
(i.e., AD18-6). Be sure you have selected an appropriate date range. 
The Commission also offers a free service called eSubscription which 
allows you to keep track of all formal issuances and submittals in 
specific dockets. This can reduce the amount of time you spend 
researching proceedings by automatically providing you with electronic 
notification of these filings and direct links to the documents. Go to 
the Commission's website (www.ferc.gov), select the FERC Online option 
from the left-hand column, and click on eSubscription. Users must be 
registered in order to use eSubscription.
    The revised version of Chapter 11 is also available on the 
Commission's Division of Dam Safety and Inspections website at: 
Engineering Guidelines for the Evaluation of Hydropower Projects 
[verbar] Federal Energy Regulatory Commission (ferc.gov).
