Document Description
Southern California Edison Company (SCE) is proposing the Project, which involves two main activities: (1) repairs to three of the arches at the multiple-arch Florence Lake Dam; and (2) upgrade of the existing low-level outlet system. The proposed repairs and upgrades will not result in a change to the design or function of the dam. Upgrade of the low-level outlet system involves installation of secondary low level outlet valves as well as upgrades to meet minimum instream flow releases per the pending new Federal Energy Regulatory Commission (FERC) license for the Big Creek 2A, 8 & Eastwood Hydroelectric Project, FERC Project No. 67.

The minimum instream flow release point will remain unchanged.
Exempt Status

Reasons for Exemption
The Project also qualifies for a Class 3: New Construction or Conversion of Small Structure categorical exemption under California Code of Regulations Section 15303 because upgrade of the low-level outlet system involves installation of secondary low-level outlet valves as well as upgrades for minimum instream flow releases. No cumulative impacts or unusual circumstances are present that would present an exception to this categorization.
