PG&E is Committed to Decommissioning the Project
• Including:
– Complying with the Project Agreement on Decommissioning
– Returning diverted flow to the streams and transferring PG&E water rights to a resource agency or other entity to protect, preserve and/or enhance aquatic resources
– Timely preparation of a Decommissioning Plan and Surrender Application
– Timely implementation of the Decommissioning Plan following FERC approval of the Surrender Application

Overview of Project
Kilarc-Cow Creek Hydroelectric Project
• Began Operating in 1904 and 1907
• Operated by PG&E
• Licensed by the Federal Energy Regulatory Commission (FERC)
• Current FERC License Issued Feb. 1, 1980
• License Expired March 27, 2007 (operating on an annual license)
• Project Relicensing Started 2001
![Page 8: Kilarc-Cow Creek Hydroelectric Project Decommissioning FERC Project No. 606 Technical Meeting](https://reader035.vdocuments.us/reader035/viewer/2022081520/56815423550346895dc2242a/html5/thumbnails/8.jpg)

Overview of Project
• Project Relicensing Began in 2001
– An Application for New License was required to be filed by March 27, 2005
• Economic Issues
– Small 5 MW Project in two developments, old facilities with high maintenance for power generated
– Anticipated significant increase in instream flow requirements and construction of fish passage facilities
– Decommissioning within the “Project Agreement” framework was more economic than continuing to operate the project
– Less costly replacement power available
• Environmental Laws and Compliance Issues
– Threatened Species (Steelhead)
– Species of Concern (Fall- and Late Fall-Run Chinook Salmon, Yellow legged frogs)

Overview of Project
• In Early 2004 PG&E Decided To:
– Interrupt relicensing the Project
– Develop a Project Agreement to implement decommissioning, if no other entity relicensed the Project
• Decision Based On:
– Project economics
– Anticipated new license conditions
– Environmental benefits of decommissioning

Project Agreement
• PG&E agreed not to seek a new license
• Identified “Subjects and Desired Conditions” that would be addressed if the Project was decommissioned
• Upon decommissioning, transfer of PG&E water rights to other entity or agency to protect, preserve, and/or enhance aquatic resources
• FERC has final approval authority over decommissioning
![Page 12: Kilarc-Cow Creek Hydroelectric Project Decommissioning FERC Project No. 606 Technical Meeting](https://reader035.vdocuments.us/reader035/viewer/2022081520/56815423550346895dc2242a/html5/thumbnails/12.jpg)

Project Agreement
What Happened After the Agreement Was Signed
• PG&E filed Agreement and informed FERC of the decision not to relicense the Project (3/30/05)
• FERC “Public Notice” that the license was available (4/7/05)
• Several entities evaluated acquiring the license and Project, but ultimately did not file license application
• PG&E filed the required Surrender Schedule with FERC on 3/23/07
• Next, FERC is expected to order PG&E to develop a decommissioning plan and file a Surrender Application within 2 years
