Follow-Up Actions The following items were identified on inspection and discussed with project staff on the last day of the inspection:  Commission staff observed that the contact information on the project’s Part 8 sign had faded and become illegible (Photo 1). The licensees were directed to either replace or repair the Part 8 sign.  At Sandy Point Boat Launch, only one loaner child life vest was available at the time of inspection (Photo 2). Because the 2025 recreational season had ended by the date of the inspection, Commission staff directed the licensees to restock the child loaner life vest rack by the start of the 2026 recreational season, and to continue to do so at the start of each recreational season going forward.  One of the shower units at the Sandy Point Boat Launch was out of service at the time of inspection, and the licensees were directed to bring that unit back into use before the start of the 2026 recreational season.  Potable water was not available at several campgrounds (Hutchins Group Campground, Sundew Campground, and Mill Creek Campground) that were Document Accession #: 20251112-3021 Filed Date: 11/12/2025 Project No. 619-164 - 7 - described as providing this amenity in the Recreational Management Plan. Licensees staff outlined the various plans to address this issue but, in the interim, Commission staff required that the licensees post additional information at each affected campground to better assist the public in finding available potable water once at the campgrounds, and to provide more information about the safe uses of water at particular sites.  At the Hutchins Group Campground, which was severely affected by the Dixie Fire (Photo 3), the trailhead sign from Hutchins to Lower Bucks was also burned and no longer legible. Commission staff directed the licensees to replace the directional sign.  At Mill Creek, it was noted that a pathway to the bathrooms from one of the accessible campsites had been raised up, causing the sidewalk to have two sharp edges and decreasing the ease with which a person requiring a mobility device could access the bathrooms. Commission staff requested the licensees to smooth or in another way correct this issue until the Mill Creek Campground is more formally rehabilitated.  An aquatic plant was observed in the Grizzly Forebay, that could be an invasive water milfoil species. The licensees were directed to obtain a sample of the plant and identify it to species, to see if further actions under their Aquatic Species Management Plan would be warranted for its control and eradication.  As a recommendation, Commission staff requested that wasp abatement continue to occur for project recreational amenity structures, such as showers, bathrooms, and wildlife resistant food boxes, so that members of the public are not deterred from using these facilities. Nearly all items were requested to be completed by the start of the 2026 recreational season and that the licensees file photo documentation of the tasks’ completions by May 31, 2026. C. Comments The project was relicensed on June 16, 2022. The original license term was granted for a period of 40 years, but on rehearing, was extended to 50 years.1 The license term now ends on May 31, 2072. The project occupies federal land within the Plumas National Forest and portions of the Bucks Lake Wilderness Area. No project works are located within the Bucks Lakes Wilderness Area, but the project boundary includes federally owned land within the wilderness area. It consists of two developments, the Bucks Creek and Grizzly developments, and four dams and reservoirs pairs (Three Lakes, Bucks Lake, Lower Bucks Lake, and Grizzly Forebay). 1 ORDER ADDRESSING ARGUMENTS RAISED ON REHEARING (180 FERC ¶ 61,177), issued September 22, 2022. Docket P-619-174. Document Accession #: 20251112-3021 Filed Date: 11/12/2025 Project No. 619-164 - 8 - Three Lakes Dam impounds Milk Ranch Creek to form the Upper, Middle, and Lower lakes of the Three Lakes Reservoir, and is considered the top of the watershed. Three Lakes outflows are diverted from Milk Ranch Creek to Lower Bucks for generation at both powerhouses through the Milk Ranch Conduit, otherwise Milk Ranch Creek eventually joins the North Fork Feather River. The Milk Ranch conduit also collects and transports water from other smaller streams within the watershed on its path to Lower Bucks; these diversions occur and are accessed by the Three Lakes Road. Originally, there were 16 conduit diversions; the licensees filed their Milk Ranch Conduit Diversion Water Rights Disposition Report in 2023. The licensees are in the process of amending their water rights with State Water Resources Control Board to accurately reflect which diversions remain active. Inactive diversions were to be left in place and managed for safety, aesthetics, and environmental reasons (No. 1, 4, 5, 6, 7, and 8). The Milk Ranch Creek Diversions Management Work Plan regarding the inactive diversions has been completed, and resulted in sealing exposed intakes and diversion pipes, the removal of construction litter and debris, and the screening of air vents to prevent wildlife entrapment. The Milk Ranch Conduit Diversion No. 3 Pipeline Rebuild has also been completed, which improved the stream and road crossing. Bucks Creek is impounded by Bucks Lake Dam, and again at Lower Bucks Lake, before joining the North Fork Feather River. Water diverted from Lower Bucks Lake through the power tunnel supplies Grizzly Powerhouse generation. Water routed through the Grizzly Powerhouse is discharged into the Grizzly Forebay; Grizzly Forebay Dam also impounds Grizzly Creek. Water there can either be routed from Grizzly Forebay through a power tunnel to Bucks Powerhouse and discharged into the North Fork Feather River or released into Grizzly Creek downstream of the Grizzly Dam. The Bucks Powerhouse was severely affected by the 2018 Camp fire, which completely burned the transmission lines it connects to,2 requiring their replacement. Only within the last year were repairs completed enough to reconnect and bring the powerhouse back online. One unit at Bucks Powerhouse was generating power at the time of inspection. PG&E staff estimate that the powerhouse will resume full power generation in 2026 following the completion of repairs/replacement of the regional transmission system. Of note, the Lower Bucks Spillway Rehabilitation Project was underway and observed from a distance during the inspection (Photo 4). The construction area was not inspected because this inspection was for overall license compliance and not a special project inspection. The 2024-2025 water year was determined to be a wet water year type. Accordingly, observed flows compared to the required flows for September in a wet water year, are identified below: 2 There are no project transmission lines at the Bucks Creek Powerhouse. Instead, the powerhouse connects directly to an adjacent non-project switchyard that is part of the regional transmission system. Document Accession #: 20251112-3021 Filed Date: 11/12/2025 Project No. 619-164 - 9 - All reservoir elevations and stream flows observed were at or greater than license- required minimums when checked on the days of inspection. Lower & Middle Three Lakes water surface elevation was at its compliance point of minimum pool, at its lowest point for the year (Photo 6), and no diversions from Milk Ranch Creek. The licensees report that they are currently pursuing an amendment to the current water quality certification Condition 1 with the State Water Resources Control Board, regarding certain planned, temporary flow modifications to minimum instream flows. Currently, WQC condition 1 does not permit temporary planned modifications to the minimum flows required in Bucks Creek below Lower Bucks Lake or Grizzly Creek below Grizzly Forebay, while Article 401(d) and 4(e) condition 31 permit the minimum flows of all project instream flows to be temporarily modified for maintenance or repair of the dam, outlet facilities, and minimum flow release facilities, with prior notification to the Commission and other agencies.

Other wildlife species with special project requirements include osprey, willow flycatcher, and bats. Waterway water quality, water temperature, channel morphology, large woody material, and riparian vegetation are also monitored under the Aquatic Resources Management Plan. The Integrated Vegetation Management Plan encompasses the monitoring and management of the enhanced fen and quaking aspen grove areas, the control of invasive plant species, herbicide use, and the protection and management of special status plant species like Clarkia which can be found near the Grizzly Powerhouse. The Gravel Augmentation Plan was approved with the issuance of the new project license, and gravel was expected to be placed at two sites in Bucks Creek and one site at Grizzly Creek in 2024 or 2025, depending on the results of topographic surveys. The baselines surveys were delayed a year, with agency approval, to complete the surveys by August 1, 2024 and place gravel in 2025. However, the 2024/2025 winter was determined to be a wet water year and was expected to have changed the topographic survey results. The California SWRCB required that another survey be completed to accurately inform the gravel placements. The licensees completed the follow-up 2025 survey; however, had to request an additional extension to obtain an updated Section 401 certification regarding the gravel placement under a Section 404 activity. The new expected date to place the gravel is October 31, 2026; however, the 2025/2026 water year type may affect the applicability of the 2025 topographic survey results, if the new extension is approved by the Commission. Regarding Sierra Nevada yellow-legged frog (SNYLF), the Milk Ranch Conduit No. 8 has been sealed so that full flows are available downstream in Bear Ravine, for the benefit of SNYLF (Photo 7). The Milk Ranch Conduit diversion gate was welded in the closed position and the pipe was pinched shut, so that inflow equals outflow for Bear Ravine. The ventilation pipe was capped with mesh. Now, the management plan consists of protecting the frog and its habitat during regular operations and maintenance, and species monitoring. Seven adult frogs were observed in the 2024 monitoring efforts within two sites (site number reduced due to Normal water year type determination, greater number of sites surveyed in Wet and Dry year types through License Year 10). It should be noted that eDNA samples failed to detect SNYLF at one site that was visually confirmed to contain at least one individual upstream. The eDNA sampling also detected the presence of Batrachochytrium dendrobatidis, the chytrid fungus that causes chytridiomycosis which is fatal to the frogs, on one replicate. However, the individuals observed at that location appeared healthy and free from infection in the provided photos (both were captured and handled). The project biologist noted that Sierra Nevada yellow- legged frogs tend to exclusively occur in streams above 4,500 ft elevation while only foothill yellow-legged frogs are found below this elevation. In August 2023, the licensees self-reported tree clearing activities that occurred without willow flycatcher surveys being completed during their nesting season (a Document Accession #: 20251112-3021 Filed Date: 11/12/2025 Project No. 619-164 - 11 - requirement of 4(e) condition 51). This incident is currently pending Commission review and a final determination. Subsequently, the licensees filed a request to amend this requirement on October 31, 2024, and report that the surveys are difficult to complete before tree removal needs to be done, prior to opening the campgrounds for recreation (whenever the snow melt occurs later in the year, the date access is possible is pushed later into the year and closer to flycatcher breeding season). The licensees notified and consulted with the resource agencies to determine the best course of action to avoid a similar situation in the future. The Forest Service collaborated with the licensees to revise the condition and change the number and timing of required surveys. Commission approval of the requested amendment is currently pending. Recently, fish stocking has occurred in Bucks Reservoir only, and licensees’ staff stated that only triploid rainbow trout are stocked. In the past, project reservoirs were stocked with lake, brown, rainbow, and kokanee trout, and some of those populations remain and may still be breeding. The 2025 brook trout spawning surveys in Three Lakes are scheduled to begin in October. No redds were observed in the previous survey. Of note, a small brown bat of unknown species was observed in the Grizzly Powerhouse Access Tunnel. (2) Recreational Resources: Many members of the public enjoy fishing and boating on project reservoirs, as well as hiking, camping, and various day-use activities. There are also several commercial companies offering recreational opportunities and year-round private residences around Bucks Lake. The current Recreational Management Plan (RMP) was filed on October 3, 2019, and incorporated into the new project license. The existing recreational resources at the time of license issuance were 10 facilities around Bucks Lake, one facility at Lower Bucks Lake, three at Grizzly Forebay, and one at Three Lakes. Two new recreational facilities, the Bucks Lake Boat-in Campground and the Bucks Lake Shoreline Trail, were added to the recreational facilities of the project in the new project license. The licensees submitted a schedule amendment request regarding multiple items requiring construction and rehabilitation in the RMP in 2024. The schedule amendment request also includes changes to the Transportation Management Plan schedule to align road improvement construction with RMP construction to minimize impacts to recreators. The Transportation Management Plan schedule changes do not require FERC approval, only Forest Service agreement. The timing of some of the planned improvements have been moved up on the schedule, and some have been moved back. According to their request, the licensees plans to begin construction and updates at the Bucks Penstock Road, Sandy Point Boat Launch and Day Use Area, and Mill Creek Campground by the end of 2026; the Hutchins Group Campground access roads, water system, and reconstruction by end of 2027; the Haskins Valley Boat Launch (Photo 8) Document Accession #: 20251112-3021 Filed Date: 11/12/2025 Project No. 619-164 - 12 - and Campground updates and improvements by 2028; Lower Bucks Day Use Area and Campground roads and reconstruction by 2029; Sundew Campground and Three Lakes access roads and amenities improvement (water system replacement at Sundew) by 2030; Lower Bucks Lake Campground and Grizzly Forebay road improvements by 2031. Project staff note that the Bucks Penstock Road improvements are mostly completed, but that the downslope stabilization portion is still pending. The Grizzly Forebay Recreational Area restroom replacement and signage installation was scheduled to be completed by end of 2025 but had not started at the time of inspection (Photo 9). Project staff estimate that the work will begin soon and be completed before winter snow begins accumulating. As discussed above, wildfire risk is an ongoing hazard addressed through various project actions. Fire Risk at project campgrounds is categorized and assessed daily, with the fire risk category posted and changed on the general information boards of campgrounds following the daily meetings (Photo 10). The project’s fire risk changed from 3 to 2 during inspection. While all campsites have a fire ring, campfire uses are restricted according to the daily fire risk category and whether the campground has an in- person host to monitor the grounds. As referenced in the follow-up letter, the Hutchins Group Campground was severely burned in the Dixie Fire ( Photo 3), including its water tank, which supplied potable drinking water to its own grounds and to the Sundew Campgrounds. Hutchins Campground is currently available, cleared of hazard trees, and the restroom facilities are in working order. However, both Hutchins and Sundew have been without potable water since the fire occurred in 2018. The Mill Creek Campground had water spigots taped off, but due to water quality issues (high total chloroform counts) which was reported as a long-term issue. Project staff hypothesize that the water quality issues are linked to pipe damage and believe once the system is dug up and replaced in concert with the overall Mill Creek Campground rehab scheduled in the RMP for 2026 (updated timeline according to the schedule amendment request), the water quality issues are likely to be resolved. Vegetation clearing, and chipping or creation of slash piles were ongoing during inspection in and around several campgrounds (Photo 11). Onsite crews were observed actively working and carrying the 5-gallon water backpack suppression kit required to be equipped with every crew vehicle pursuant to 4(e) condition 61. Inspection staff also noted that project vehicles escorting the group had the required shovel, water backpack, and ABC fire extinguisher in the company vehicle (Photo 12). Active construction was observed at the Bucks Powerhouse, crews were in the process of installing a non-conductive fence around the powerhouse, estimated to be completed by the end of the year, with the purpose of allowing additional for public use and parking near the powerhouse for recreation in the North Fork Feather River. (3) Public Safety: Document Accession #: 20251112-3021 Filed Date: 11/12/2025 Project No. 619-164 - 13 - The project appears in overall compliance with its public safety plan (Example: Photo 13). The latest public safety plan was revised and filed on July 8, 2025, and accepted by Division of Dam Safety and Inspection – San Francisco Regional Office on August 15, 2025. (4) Other Environmental Requirements: The project appears in overall compliance regarding its other environmental requirements. The current versions on the Spill Prevention Containment and Control Plan and its Hazardous Material Management Plan were observed easily accessible and onsite at the Bucks Creek Powerhouse. It was noted that at both powerhouses, the transmission yards and houses were self-contained and drain into the sumps without possible direct discharges to waterbodies (i.e., a catastrophic spill would be contained at these locations would drain to the sump and require a pump and haul operation out for removal). The staff hydrologist reported that all battery packs in the stream gaging and reservoir level stations were supplied with gel-type packs (Photo 14), reducing risk of contamination. (5) Cultural Resources: The Mountain Maidu and Konkow Maidu have ties to land within the project boundary. Cultural resource areas and sites are monitored under the Historic Properties Management Plan, at least once every two years. The last monitoring and site condition assessment effort conducted in 2024 surveyed approximately 50 locations and identified five sites that showed signs of disturbance or changed and recommended a project response. Cultural and historical informational signs were observed at Indian Rock Day Use Area (Photo 15), that explain the significance of the area. At this recreational facility, multiple large mortar rocks are observable. The project area contains historical resources relating to the Sierra Nevada’s part of the Gold Rush and the Euroamerican miners that migrated to California starting in 1849. Along with the influx of Europeans, Bucks Ranch was established and by 1900, became a supply outpost, waystation, and agricultural center of the local region. In the 1920s however, the area had gained the interest of hydropower developers. This area was flooded and became Bucks Lake Reservoir with the creation of the Bucks Creek Hydroelectric Project. The first license for the project was issued by the Federal Power Commission in 1925, and an original operating center and switchboard still occupies Bucks Powerhouse, built in 1926, though it is now disconnected (Photo 16).
