LAKE CLEMENTINE HYDRO, LLC October 17, 2014 Ms. Kimberly Bose, Secretary Federal Energy Regulatory Commission 888 First Street, NE Washington, DC 20426 Subject: Lake Clementine Project (FERC Project No. 13432) Completion of First Stage Consultation and Study Plans to Prepare License Application Dear Secretary Bose: Lake Clementine Hydro, LLC (LCH) has completed First Stage Consultation for the Lake Clementine Hydroelectric Project, Federal Energy Regulatory Commission (FERC) Project No. 13432 (Project), as required by 18 CFR § 4.38 for the Traditional Licensing Process. This filing contains: • Summarized comments and recommendations received during First Stage Consultation activities; • LCH’s responses to the comments and recommendations; and • Study plans for individual resources that LCH will implement to collect information necessary to prepare the Project license application. An initial Preliminary Permit for the Project was issued on October 29, 2009. On August 30, 2010, LCH filed a Pre-Application Document and a Notice of Intent to file a license application with a request to use the Traditional Licensing Process. FERC approved the Traditional Licensing Process on October 10, 2010. LCH held a site visit and joint agency and public meeting on December 12, 2010. FERC issued a subsequent Preliminary Permit to LCH on March 21, 2013. On March 12, 2014, LCH held a site visit and joint agency and public meeting to update stakeholders on current Project plans. LCH distributed an applicant-prepared scoping document and a set of draft resource study plans to agencies and stakeholders for review and comment.

In response to the comments received, LCH developed or revised the following study plans, which are attached: Water Quality Study Plan (WR-S 1) Amphibian and Reptile Study Plan (TR-2) Water Quantity Study Plan (WR-S2) Wildlife Study Plan (TR-3) Sediment Transport Study Plan (WR-S3) Recreation Resources Study Plan (RR-1) Fisheries Study Plan (AQ-1) Visual and Aesthetic Resources Study Plan (RR-2) Fish Entrainment Study Plan (AQ-2) Socioeconomic Resources Study Plan (RR-3) Special-Status and Invasive Plant Study Plan (TR- 1) Cultural and Historic Properties Study Plan (CR-i) LCH is ready to begin collecting resource information for developing the Project license application. However, study plan implementation is contingent on receiving permits and Lake Ctementine Hydro, LLC 46 PeninsuLa Center, Suite E RoLLing HiLLs Estates CA 90274 USA I I The Honorable Kimberly D. Bose, Secretary Federal Energy Regulatory Commission October 17, 2014 Page 3 permission for site access from the U.S. Army Corps of Engineers and Bureau of Reclamation. In spite of LCH’s efforts during the last 6 months to obtain permits and permission for site access, it does not appear that these items will be received in time to collect meaningful data in 2014. Assuming the needed permits and permission for site access are received in the near ftture, the studies will be implemented in 2015, allowing for only one study season for most resource studies. If you have any questions or require additional information, please contact Mr. Daniel Parker, Project Manager at (315) 261-2158 or [email protected].

These issues are: Issue: Project effects on reservoir water temperature and dissolved oxygen (DO) stratification. Issue: Project effects on water temperature and DO in Lake Clementine and downstream of North Fork Dam. Issue: Available water quality data are insufficient to describe water quality under existing conditions that may be influenced by the proposed Project. Issue: Supersaturated levels of dissolved gases can have adverse effects on fish. Diverting water through the proposed powerhouse would reduce flows over the spillway and may reduce total dissolved gas (TDG) levels downstream of the dam. Without baseline data on TDG, it would be unclear if this could represent a beneficial Project effect. Issue: Adequate information regarding ambient levels of water constituents is not available. The goal of this study is to develop the essential information necessary to supplement existing information addressing the identified issues. In this case, the objectives of this study are to describe existing conditions and analyze the potential for change to the existing conditions as a result of Project construction and operation. This information would also be used to determine if the Project will comply with the water quality criteria described in The Water Quality Control Plan (Basin Plan) for the California Regional Water Quality Control Board Central Valley Region, Fourth Edition, The Sacramento River Basin and the San Joaquin River Basin (Basin Plan). The information will also be used to determine the need for mitigation measures to protect beneficial uses and aquatic resources of the North Fork of the American River (NFAR). Additionally, this information would be used in LCH’s application to the State Water Resources Control Board for water quality certification for the Project. Specifically the study objectives are to: 1 October 17, 2014 Lake Clementine Hydroelectric Project, FERC No. 13432 ©2014, Lake Clementine Hydro, LLC Lake Clementine Hydroelectric Project, FERC No. 13432 Water Quality Study Plan Characterize existing water quality in NFAR upstream of Lake Clementine, in Lake Clementine, and in NFAR downstream of North Fork dam. Identify the DO and temperature profiles near the dam and the proposed intake structure. Identify any seasonal or temporal variations in DO concentration and water temperature. Identify and describe the timing of reservoir stratification. Describe DO and water temperature in the NFAR immediately upstream of Lake Clementine and immediately downstream of the dam and powerhouse location. EXISTING INFORMATION The Project would be located at Lake Clementine adjacent to North Fork Dam on the NFAR in Placer County, California. Lake Clementine, which was formed by the North Fork debris dam constructed in 1939, is now owned by the U.S. Army Corps of Engineers (USACE). Lake Clementine has a surface area of 280 acres, a capacity of 14,700 acre-feet, and is approximately 3.5 miles (mi) long. The dam rises 155 feet (ft) above the lowest foundation and has a spillway crest elevation of 715 ft. The dam crest length is 620 ft and the thickness varies from 22 ft at the base to 6.8 ft at the top. The proposed Project would consist of an intake near the left abutment of North Fork Dam, an open canal, and one or two penstocks connecting to a powerhouse that would house two or three generating units, totaling a combined capacity of 16 megawatts. The powerhouse would be located between 200 and 600 ft downstream of the dam. Construction of the intake, canal, and penstock intakes would require excavating the slope on the south side of the canyon adjacent to the dam. A switchyard consisting of a station generator bus, station service transformer, a step-up transformer, and circuit breaker would be located at an elevation above the high flood flow elevation of the NFAR near the powerhouse or in a room of the powerhouse building. A 60- kilovolt transmission line would be constructed to connect the switchyard with Pacific Gas and Electric’s Halsey Substation. The exact location of the transmission line has not been determined at this time. Two alternative access routes are being considered for Project construction. One access route option would entail reconstructing a 2.5-mile-long access road on the south side of the NFAR between Old Foresthill Road and North Fork Dam. The route would follow the alignment of an abandoned dirt road that is currently used as a hiking and biking trail. After construction is completed, the road either could be removed and the site restored or could remain in place to serve another purpose, such as an emergency access or a recreation trail.
