The project is located on Sucker Run Creek, in Butte County, California. The project does not occupy any federal lands. I.Background 2.The minor license for the 1.2-megawatt (MW)2 project was issued on August 15, 1985, for a term of 50 years, expiring on July 31, 2035.3 As licensed, the project consists of: (1) a 12-foot-high, 36-foot-long concrete diversion structure with a 24-inch drain gate located at elevation 1,672-feet mean sea level (msl)with no significant storage; (2) a 30-inch-diameter, 5,669-foot-long pipeline/penstock, with both above-ground and buried sections;(3) a 24-inch-diameter discharge drain gate at the base of the dam; (4) a 35-foot by 38-foot powerhouse, located at elevation 1,130 feet msl, containing a single 1 The application was supplemented on February 28 and April 28, 2023, July 17, 2024, and March 3, 2025. 2 Television Communications Inc., 32 FERC ¶ 62,333 (1985)(issuing a license with a nameplate capacity of 1.12 MW); STS Hydropower, Ltd., 72 FERC ¶ 62,265 (1995) (amending the nameplate capacity from 1.12 MW, as originally licensed,to 1.2 MW). 3 Television Communications Inc., 32 FERC ¶ 62,333 (1985). See also RDS Company,43 FERC ¶ 62,223 (1988). The project license was transferred multiple times including on August 27, 1987 (40 FERC ¶ 62,235), September 30, 1988 (44 FERC ¶62,343), and finally to STS Hydropower, LLC on October 6, 2017 (161 FERC ¶62,017). Document Accession #: 20250915-3012 Filed Date: 09/15/2025 Project No. 7242-060 -2 - 1,500 horsepower impulse turbine connected to a 1.2 MW generator; (5) a 771-foot-long, 12-kilovolt (kV)tap line to interconnect the project with an existing transmission line;4 and (6) appurtenant facilities. 3.The project is located entirely on remote, private lands with limited access. The licensee leased the privately-owned dam for project operation. The project previously operated in a run-of-river mode. Article 21 of the license requires a minimum flow of 5- 13 cubic feet per second (cfs), or inflow, whichever is less, depending on the time of year released into the bypassed reach. Due to limited inflow, the project is typically off-line from July-October, and all inflow is released at the dam. 4.The project has been inoperable since August 2017 when the powerhouse, transmission lines, and electrical equipment were destroyed by the Ponderosa Wildfire (fire). Considering the extensive damage to these project features, STS determined that it is not cost effective to restore project operation. Instead, STS proposes to surrender the project license and remove certain project features. 5.Beginning in September 2021, the licensee informed the Commission of its proposal for general clean-up of the project area following the fire. These activities were authorized by the Commission’s Division of Dam Safety and Inspections (D2SI)-San Francisco Regional Engineer (D2SI-San Francisco Regional Engineer) by letter dated January 13, 2022.5 In May 2022, the remains of the tap line and associated transmission line were removed during site clean-up.6 II.Proposed Surrender 6.The licensee proposes to surrender and decommission the project by completing the following activities: (1) installing approximately 60-inches of concrete to plug the penstock and welding the upper and lower ends closed; (2) permanently sealing the penstock flap gate in the wet well and filling the wet well with sand and gravel; (3) 4 According to information included with the surrender application, Pacific Gas and Electric Company owns the transmission line that serves the project and has no plans to rebuild the line following the fire. 5 Commission Staff’s January 13, 2022 Letter to Eagle Creek Renewable Energy, LLC. Clean-up activities included: restoration of parts of the access road; repair of the security gate; removal of the 771-foot-long tap line serving the project; disassembly of damaged transmission poles and removal; and general debris removal in the powerhouse area. 6 STS’s July 17, 2024 Response to Commission Staff’s Additional Information Request,at 3. Document Accession #: 20250915-3012 Filed Date: 09/15/2025 Project No. 7242-060 -3 - removing all mechanical and electrical equipment; (4) demolishing the aboveground portion of the powerhouse building and substation and hauling material offsite to an area landfill (the buried powerhouse foundation would remain); (5) filling the tailrace with native rocks and soils and regrading the area to match surrounding slopes; and (6) regrading the disturbed areas that previously contained the powerhouse and surrounding road. The licensee proposes to leave the penstock and existing privately-owned dam in place, with the penstock permanently sealed to prevent water entry. All flow would be released at the dam, primarily through the drain gate, following surrender. 7.The licensee proposes to adhere to best management practices (BMPs) to ensure any effects from decommissioning activities are temporary and limited in geographic scope. These BMPs include: Scheduling construction activities in late summer or fall; Protecting roots of established vegetation where possible; Stabilizing construction vehicle entrances and exits; Using proper containment, removal, and disposal of construction debris and waste, and complying with all state and local regulations governing disposal; Using temporary erosion control mats or blankets and minimal hydroseeding; Using biodegradable hydraulic fluids for any equipment operating in the stream channel; Ensuring proper maintenance of construction vehicles and equipment to prevent leaks; Developing a stormwater pollution prevention plan (SWPPP) prior to any ground disturbance; Developing a final construction plan that includes all appropriate BMPs following Commission action on the surrender; Providing fueling of equipment in designated upland locations with adequate spill prevention measures in place; and Provisions to cease work and consult with appropriate Tribes and resource agencies in the event of an inadvertent discovery of Tribal or cultural resources. 8.Following Commission approval and receipt of all necessary permits, the licensee plans to complete the decommissioning activities and site cleanup during late summer and fall. While no in-water work is anticipated, this schedule coincides with the low- flow season in the event in-water work is necessary. Document Accession #: 20250915-3012 Filed Date: 09/15/2025 Project No. 7242-060 -4 - III.Pre-filing Consultation and Public Notice 9.The licensee included with its application documentation of pre-filing consultation with the U.S. Forest Service (Forest Service), U.S. Fish and Wildlife Service (FWS), California Department of Fish and Wildlife (California DFW), California State Historic Preservation Officer (California SHPO), and the California State Water Resource Control Board (California SWRCB). Beginning on January 25, 2021, the licensee met with the consulted parties to discuss the extent of project damage, the proposed decommissioning, and the anticipated schedule for decommissioning. A follow-up meeting was held on August 25, 2021. On April 4, 2022, the licensee provided the consulted parties a draft surrender application for review and comment. Comments were received from the California SWRCB and the California DFW.The licensee included a response to these comments in Appendix B of the application and accordingly revised the application prior to filing with the Commission on September 30, 2022. 10.The Commission issued public notice of the surrender application on March 23, 2023, setting April 24, 2023,7 as the deadline to file protests, comments, and motions to intervene. On April 24, 2023, the California SWRCB filed a timely motion to intervene. On May 1, 2024, the California DFW filed a late motion to intervene, which was denied on October 16, 2024.8 IV.Statutory Compliance A.National Environmental Policy Act 11.Commission staff issued a notice of intent to prepare an Environmental Assessment (EA) for the proposed surrender of the project on January 29, 2024. The notice provided a proposed schedule for completion of the EA. In the notice, Commission staff also invited federal, state, and local agencies, as well as Tribes, to 7 The Commission’s Rules of Practice and Procedure provide that if a filing deadline falls on a Saturday, Sunday, holiday, or other day when the Commission is closed for business, the filing deadline does not end until the close of business on the next business day. 18 C.F.R. § 385.2007(a)(2) (2025). Because the 30-day deadline fell on a Saturday (i.e., April 22, 2023), the filing deadline was extended until the close of business on Monday, April 24, 2023. 8 See Notice Denying Late Intervention, issued October 16, 2024. Accession # 20241016-3002. https://elibrary.ferc.gov/eLibrary/filelist?accession_number=20241016- 3002&optimized=false&sid=e016c896-9db3-4b13-b466-7f2aba1b9ac9. Document Accession #: 20250915-3012 Filed Date: 09/15/2025 Project No. 7242-060 -5 - cooperate in the preparation of any environmental document. No requests to be a cooperating agency were received. 12.To satisfy the Commission’s responsibilities under the National Environmental Policy Act of 1969 (NEPA),9 and the Commission’s implementing regulations under 18 C.F.R.§380,Commission staff issued an EA on August 22, 2024,addressing the environmental effects of the proposed surrender, a full dam removal alternative, and the no-action alternative. No comments on the EA were received. 13.In the EA,Commission staff found that there would be no adverse effects to water quality, water quantity, aquatic resources, terrestrial resources, or wetlands from the proposed surrender of the project license because no in-water work is anticipated. The EA identified only minor, short-term adverse effects would occur for geology and soils, terrestrial resources, land use,and aesthetic resources during decommissioning activities. No formal recreation facilities were required as part of the project license and no effect on recreation resources would occur. Commission staff identified a minor beneficial effect on aquatic resources resulting from the elimination of the diversion of flow to the powerhouse for hydropower generation,as well as a beneficial effect on aesthetics from removing damaged project equipment and restoring the project area. 14. In the EA, Commission staff concluded that approving surrender of the license would not result in significant adverse effects to environmental resources, and no additional mitigation measures are recommended. Commission staff concluded that the surrender, as proposed,would not constitute a major federal action significantly affecting the quality of the human environment.10 B.Clean Water Act 15.Under section 401(a)(1) of the Clean Water Act (CWA),11 any applicant for a federal license or permit to conduct activities that may result in a discharge into United States waters, must obtain either a water quality certification (certification) from the appropriate state pollution control agency verifying that any discharge from the project would comply with applicable provisions of the CWA or a waiver of such certification. If the state “fails or refuses to act on a request for certification, within a reasonable period 9 42 U.S.C. §§ 4321 et seq.; see also 18 C.F.R. pt. 380 (2025) (Commission’s regulations implementing NEPA).The Council on Environmental Quality’s (CEQ) final rule rescinding its NEPA regulations became effective on April 11, 2025.90 Fed.

On April 23, 2024, the California SWRCB denied the request for a certification. On April 29, 2024, Commission staff requested that the licensee either file an appeal of this decision or a new certification request. On July 15, 2024, the licensee reapplied to the California SWRCB for certification. On July 15, 2025, California SWRCB issued a certification for the surrender and decommissioning of the project. 17.Conditions 1 and 6 through 25 are general or administrative and are not discussed further. Condition 2 requires the licensee to develop and submit for approval to the California SWRCB a Dewatering and Water Quality Monitoring Plan that includes but is not limited to a description of all construction-related activities, maps, schedule, BMPs, and water quality monitoring during the work. Condition 3 requires general erosion control and hazardous material control measures, compliance with the National Pollutant Discharge Elimination System General Permit for Stormwater Discharges Associated with Construction and Land Disturbance Activities, and submittal for approval to the California SWRCB and the Commission a Water Quality Monitoring and Protection Plan for any ground-disturbing activities not covered by other conditions. Condition 4 requires protective measures for California red-legged frogs, foothill yellow-legged frogs, and northwestern pond turtles as well as environmental awareness training. These species are listed or proposed for listing under the Endangered Species Act (ESA), as discussed below. Condition 5 requires a report to the California SWRCB prior to beginning the work as well as a separate report when the work is completed. 18.The conditions of the certification are set forth in Appendix A of this order and required by ordering paragraph (B). C.Threatened and Endangered Species 19.Section 7 of the ESA12 requires federal agencies to ensure their actions are not likely to jeopardize the continued existence of federally listed threatened or endangered species or result in the destruction or adverse modification of the critical habitat of such species. 12 16 U.S.C. § 1536. Document Accession #: 20250915-3012 Filed Date: 09/15/2025 Project No. 7242-060 -7 - 20.Based on the FWS Information for Planning and Consultation (IPaC) website,13 Commission staff in February 2024 identified two federally listed species, the California red-legged frog (Rana draytonii) and the foothill yellow-legged frog (Rana boylii), both listed as threatened under the ESA as being in the project area. The Northwestern pond turtle (Actinemys marmorata), the California spotted owl (Strix occidentalis occidentalis), and the monarch butterfly (Danaus plexippus),14 currently proposed for listing as threatened, were also identified as being found in Butte County, California. No critical habitat for any federally listed species occurs within the project area. 21.As discussed in the EA, Commission staff determined that the proposed surrender and decommissioning activities may affect but is not likely to adversely affect the listed California red-legged frog and the foothill yellow-legged frog. On August 23, 2024, staff requested written concurrence on our determination from the FWS and on May 14, 2025, the FWS concurred with staff’s determination.15 This concurrence followed consultation between the FWS and the licensee regarding protection of these species during the cleanup. The agreed-upon conservation measures identified in FWS’s May 14, 2025 letter16 include: (1) conducting a pre-construction survey (no more than 3 days prior to the start of ground disturbance) within the project area and a 500-foot buffer zone around the project area; (2) conducting daily surveys in the immediate project area by a qualified biologist prior to initiating work; (3) ceasing all work activities in the event that a listed species is found in project area and immediately contacting the FWS for further guidance (to include photographs if possible);(4)avoiding erosion control measures that contain monofilament; (5) screening any pump intakes with wire mesh no larger than 5 millimeters; (6) educating workers on the federally listed species that have potential to occur within the project area and reporting requirements; and (7)fueling construction equipment in designated upland areas. These measures are set forth in Appendix B of this order and are required by ordering paragraph (C). 22.Commission staff notes that the certification, discussed above,also includes provisions for the protection of these listed species as well as the northwestern pond 13 IPaC, FWS, https://ipac.ecosphere.fws.gov/(accessed February 7, 2024). 14 At the time Commission staff accessed the IPaC website, the monarch butterfly was a candidate species, but is currently proposed for listing as threatened. 89 Fed. Reg. 100,662 (Dec. 12, 2024). 15 Commission Staff’s June 23, 2025 Memorandum attaching FWS’s Response. 16 These conservation measures are in addition to certain measures already proposed by the licensee. Document Accession #: 20250915-3012 Filed Date: 09/15/2025 Project No. 7242-060 -8 - turtle, that is proposed for listing. Those provisions are consistent with the FWS’s conservation measures above and are made part of this surrender order in Appendix A. 23.On July 3, 2025, Commission staff again accessed the FWS’s IPaC website to identify any changes to the species list. Since February 2024, two species were added to the list. These species include the gray wolf (Canis lupus), listed as endangered, and a non-essential experimental population of California condor (Gymnogyps californianus). Given the lack of habitat in the project area after the fire and the transient nature of the endangered gray wolf, Commission staff finds there would be no effect of the proposed surrender and decommissioning of the project on this species. Commission staff also considered potential effects to those species proposed for listing, as well as the experimental population of California condor,and finds that the proposed surrender and decommissioning would not jeopardize the continued existence of these species. We consider our consultation under section 7 of the ESA complete. D.National Historic Preservation Act 24.Section 106 of the National Historic Preservation Act (NHPA)17 and its implementing regulations18 require federal agencies to take into account the effect of any proposed undertaking19 on properties listed or eligible for listing in the National Register of Historic Places (National Register), defined as historic properties,and afford the Advisory Council on Historic Preservation (Advisory Council)a reasonable opportunity to comment on the undertaking.This generally requires the Commission to consult with the State Historic Preservation Officer (SHPO)to determine whether and how a proposed action may affect historic properties, and to seek ways to avoid or minimize any adverse effects. 25.Here, the proposed surrender of the project includes cleanup from the fire that significantly damaged critical project features in 2017. No historic properties are known to occur within the project area. On August 17, 2021, Commission staff designated the licensee as our non-federal representative for the purposes of consultation under section 17 54 U.S.C. § 306108. 18 36 C.F.R. pt.800 (2024). 19 An undertaking means “a project, activity, or program funded in whole or in part under the direct or indirect jurisdiction of a Federal agency, including those carried out by or on behalf of a Federal agency; those carried out with Federal financial assistance; and those requiring a Federal permit, license, or approval.”Id.§ 800.16(y).Here, the undertaking is the proposed surrender of the project and cleanup of the area following the fire. Document Accession #: 20250915-3012 Filed Date: 09/15/2025 Project No. 7242-060 -9 - 106 of the NHPA. By letter dated March 2, 2023, the licensee requested concurrence from the California SHPO that surrender and decommissioning of the project would not adversely affect historic or cultural resources in the project area. On April 18, 2023, the California SHPO concurred. Thus,consultation under section 106 of the NHPA is complete. V.Dam Safety 26.The project dam is classified as having a low hazard potential because there is no development in the downstream area that a failure of this water-retaining structure would inundate. The project was last inspected by the Commission’s D2SI –San Francisco Regional Engineer on June 7, 2023.20 No outstanding dam safety issues were identified during the inspection. In the inspection report,Commission staff noted that the preliminary clean-up of the site was completed on April 6, 2022.21 On July 6, 2023, staff issued a letter reminding the licensee of its responsibility of an annual submittal to request a continuing exemption from filing an Emergency Action Plan. No other recommendations were made after the inspection. 27.When a project is surrendered, the Commission’s jurisdiction over the project ends and future dam safety oversight of any remaining works often becomes the responsibility of the state entity with regulatory authority. On May 17, 2023, the D2SI-San Francisco Regional Engineer contacted the California Department of Water Resources, Division of Safety of Dams (California DSOD) to discuss the proposed surrender of the project. The California DSOD was informed of the proposed surrender and by letter dated May 18, 2023, indicated that the dam would not fall under California DSOD jurisdiction.22 28.Based on the recent inspection, Commission staff finds there is no reason to deny surrender of the project license for dam safety issues. Commission staff recommends the licensee decommission the project as proposed and be required to file with the D2SI-San Francisco Regional Engineer:(1) final plans and specifications for the decommissioning activities (to include all supporting construction related documents, e.g., supporting design report, Quality Control and Inspection Program, Temporary Construction Emergency Action Plan, and Soil Erosion and Sediment Control Plan); (2) documentation of independent review and approval of any cofferdam or deep excavation plans should they be needed for decommissioning; and (3)a final decommissioning report once 20 See Commission Staff’s February 20, 2024 Dam Safety Inspection Report. 21 See id.; see also STS’s May 27, 2022 Site Cleanup Status Update, at 4; Commission Staff’s July 19, 2022 Letter, at 1 (confirming review and satisfaction with STS’s May 27, 2022 status update). 22 California DSOD June 28, 2023 Letter on Jurisdiction, at 1. Document Accession #: 20250915-3012 Filed Date: 09/15/2025 Project No. 7242-060 -10 - activities are complete. Surrender of the project would not be effective until the D2SI- San Francisco Regional Engineer issues a letter that states all decommissioning work has been completed. VI.Discussion and Conclusion 29.Section 6 of the Federal Power Act (FPA) allows licensees to voluntarily surrender existing licenses and cease operating project works, providing that licenses “may be . . . surrendered only upon mutual agreement between the licensee and the Commission after thirty days’ public notice.”23 The Commission, in acting on a surrender application, applies a broad “public interest” standard24 and may require conditions consistent with the FPA as it finds to be in the public interest.25 30.A licensee requests surrender of a Commission-issued license when it decides it no longer wishes to hold that license, which can happen for a variety of reasons. When a licensee voluntarily decides to surrender its license, the Commission’s regulations require the licensee to file a surrender application that includes a decommissioning plan.26 Possible forms of decommissioning range from simply shutting down the power operations to removing all parts of the project, including the dam, and restoring the site to its pre-project condition. The Commission will only approve a license surrender once the licensee has fulfilled its obligations as established by the Commission.27 31.The project was significantly damaged in the 2017 fire and is no longer operable, thus it currently does not provide the public benefit of clean, renewable energy. The licensee found continued operation of the project was not cost-effective with the expected costs associated with restoring the project, decreasing revenues, and power prices. The licensee does not propose to remove the project dam.

Document Accession #: 20250915-3012 Filed Date: 09/15/2025 Project No. 7242-060 -11 - Commission staff identified no significant adverse effects to environmental resources resulting from the proposed surrender of the project. 32.Additionally, this order requires the agreed-upon conservation measures recommended by the FWS for the protection of the listed California red-legged frog and the foothill yellow-legged frog during decommissioning, as well as California SWRCB’s water quality certification, attached as Appendix A. This order also requires the filing of final plans and specifications on decommissioning with the Commission’s D2SI-San Francisco Regional Engineer, including the approved design of any cofferdams and deep excavations, should any be necessary during decommissioning. 33.Lastly, this order requires the filing of a final decommissioning report once all decommissioning activities have been completed. This surrender will not be effective until the Commission’s D2SI-San Francisco Regional Engineer issues a letter finding that the conditions of this order have been satisfied. With these conditions, we find the surrender of the license to be in the broad public interest, and the surrender application should be approved. The Director orders: (A)STS Hydro, LLC’s (licensee) application to surrender the license for the Kanaka Hydroelectric Project No. 7242, filed on September 30, 2022,and supplemented on February 28 and April 28, 2023, July 17, 2024, and March 3, 2025,as modified in paragraphs (B) through (H), is approved. (B)This surrender is subject to the conditions submitted by the California State Water Resources Control Board under section 401(a)(1) of the Clean Water Act, 33 U.S.C. § 1341(a)(1), as those conditions are set forth in Appendix A to this order. (C)The licensee must implement the conservation measures identified in the U.S. Fish and Wildlife Service’s (Service) May 14, 2025 letter,as those conditions are set forth in Appendix B to this order. (D)The licensee must complete the decommissioning activities as proposed in the surrender application including but not limited to: removing the powerhouse structure, sealing the penstock, filling the tailrace, removing all mechanical and electrical equipment, and grading the disturbed areas to match surrounding slopes. (E)At least 60 days prior to the start of any construction associated with the decommissioning activities, the licensee must file final design documents with the Commission by eFiling to the Commission’s Division of Dam Safety and Inspections (D2SI)-San Francisco Regional Engineer (D2SI-San Francisco Regional Engineer). The design documents must include: final plans and specifications, supporting design report, Document Accession #: 20250915-3012 Filed Date: 09/15/2025 Project No. 7242-060 -12 - Quality Control and Inspection Program, Temporary Construction Emergency Action Plan, and Soil Erosion and Sediment Control Plan. The licensee may not begin construction until the D2SI-San Francisco Regional Engineer has reviewed and commented on the documents, determined that all preconstruction requirements have been satisfied, and authorized the start of construction. (F)Should decommissioning activities require cofferdams or deep excavations, the licensee must: (1) have a Professional Engineer who is independent from the construction contractor, review and approve the design of contractor-designed cofferdams and deep excavations prior to the start of construction; and (2) ensure that construction of cofferdams and deep excavations is consistent with the approved design.
