Order Conditions |
Discharge of hazardous waste into FA1, a Class III WMU, and FA2, a Class II WMU, in violation of Prohibition 2 of the WDRs. In a 22 April 2025 email, the Discharger notified Central Valley Regional Water Quality Control Board (Central Valley Water Board) staff of the possible disposal of non-RCRA Hazardous Waste at the Facility. Within the 29 April 2025 PG&E Disposal Notification, the Discharger self-reported the acceptance and disposal of 16.62 tons of Hazardous Waste sludge into FA2. The Hazardous Waste originated from a Pacific Gas & Electric (PG&E) power pole replacement project occurring adjacent to the Potrero MGP Northern Switchyard in San Francisco, CA. Instead of placing onsite spoils in the bin provided for the project, the hydrovac contractor (Discovery Hydro) transported the wet spoils to the PG&E Oakport spoils yard and dumped approximately 200 gallons of untested wet spoils into a non-hazardous wet spoils bin on 11 March 2025. Once at the spoils yard, excess free liquid was decanted, and the remaining sludge was sent to the Altamont Landfill. Samples were collected from the PG&E project site, down to seven feet below ground surface on 10 April 2025, and the results confirmed elevated concentrations of chromium and nickel above established California (non-RCRA) Hazardous Waste levels. Due to the proximity of the sample location to the pole replacement location, and the lack of data associated with the original waste stream, PG&E and the Discharger presume that the disposed sludge is California (non-RCRA) Hazardous Waste. According to PG&E, these elevated detections are the result of naturally occurring serpentinite. The Total Threshold Limit Concentrations (TTLCs) detected for chromium and nickel were 805 mg/kg and 1,160 mg/kg, respectively, which are below RCRA Hazardous Waste levels. However, the Soluble Threshold Limit Concentrations (STLCs) detected for chromium and nickel were 12.5 mg/L and 83 mg/L, respectively, which exceed the California Hazardous Waste levels for these constituents. The California Hazardous Waste limits for chromium and nickel are 5 mg/L and 20 mg/L, respectively. Therefore, the subject PG&E waste the Discharger accepted and disposed in FA2 is a Hazardous Waste, and it must be removed, transported, and disposed of accordingly to return to compliance with the WDRs |

Violation 1 ? In a 31 January 2024 email, the Discharger asked Central Valley Regional Water Quality Control Board (Central Valley Water Board) staff if they could transfer leachate from SI-1 to SI-2, to increase the freeboard level in SI-1. Central Valley Water Board staff informed the Discharger that a transfer of leachate between the Facility?s two surface impoundments is prohibited by the WDRs, and therefore, a transfer of leachate from SI-1 to SI-2 should only occur if absolutely necessary to prevent a release. Central Valley Water Board staff also discussed other potential liquid storage options with the Discharger. On 6 February 2024 the Discharger reported that freeboard levels in SI-1 had dropped to 1.4 feet, below the two feet of freeboard required by the WDRs and Title 27. In a 7 February 2024 email, the Discharger stated that they were holding off on pumping leachate from SI-1 to SI-2. However, they had ordered five 21,000-gallon liquid storage tanks and were working on a plan to transport and dispose of 100,000 gallons of leachate at the Yolo County Central Landfill in Woodland. Since 6 February 2024 the freeboard level in SI-1 has remained under 2 feet, and as of 14 April 2024 the freeboard level in SI-1 was recorded at 0.75 feet. During this same time period, the Discharger has transferred 240,000-gallons of leachate from SI-1 into twelve onsite 21,000 gallon liquid storage tanks and 17,000-gallons of leachate from SI-1 to the Yolo County Central Landfill. |

The legal requirements outlined below are specific to the violation noted above. 1. Section 21750(f) of Title 27 states in part: ?A stability analysis, including a determination of the expected peak ground acceleration at the Unit associated with the maximum credible earthquake (for Class II waste management units) or the maximum probable earthquake (for Class III landfills). This stability analysis shall be included as part of the ROWD (or JTD) for the proposed Unit, and an updated stability analysis (if the original analysis no longer reflects the conditions at the Unit) shall be included as part of the final closure and post-closure maintenance plan? The addition of soil material onto these previously closed Modules has invalidated any previously approved slope stability analysis. The original analysis no longer reflects the conditions of the Unit. The absence of an approved stability analysis is a violation of Title 27. 2. Finding 40 of the WDRs states in part: ?The Discharger has been implementing measures proposed in the 23 September 1997 Corrective Action Program and subsequent addendum. The CAP specifies the following actions: installation of 8 infill gas wells; closure of Modules 1, 2, 10, 11 and 12? While it is practice to allow a Discharger to manipulate the system to optimize the extraction of landfill gas, the removal of 17 of the systems 22 wells would be an unapproved system modification. This significant reduction of the landfill gas system Further, Section 20430(f) of Title 27 address the termination of corrective action measures and states: ??corrective action measures taken pursuant to ¶(c)(e.g., pumping and treatment of ground water) may be terminated when the discharger demonstrates to the satisfaction of the RWQCB that the concentrations of all COCs are reduced to levels below their respective concentration limits throughout the entire zone affected by the release.? No demonstration of compliance was provided. These WMU Modules are still in corrective action. For these reasons, the removal of landfill gas wells from a unit in corrective action, without Regional Board approval is a violation of Title 27. 3. Finding 70 of the WDRs states in part: ?The RWD/JTD submitted by the Discharger contains a preliminary closure and post-closure maintenance plan (PCPCMP) for the landfill. The PCPCMP includes information required by Title 27 CCR Section 21769(b), and includes a lump sum estimate of the cost of carrying out all actions necessary to close each Unit, to prepare detailed design specifications, to develop the final closure and post-closure maintenance plan, and to carry out the first thirty years of post-closure maintenance. The total amount of the closure cost estimate is $16,846,912, and the amount of the post-closure maintenance cost estimate is $7,374,807. The Regional Board hereby approves these cost estimates.? Like the now invalid seismic analysis, the new morphology of Modules 1, 2, 10 and 11, creates a conflict with the WDRs. Therefore, the financial assurance estimates are no longer applicable and must be recalculated. |

Violations: 1. The Discharger has failed to place and/or maintain an adequate layer of daily or intermediate cover at three separate locations across LF-2. Scattered worked-in waste was present at all three locations were only daily or intermediate cover soil should be located. Exposed waste in areas of the WMU outside the active face of a WMU is a violation of Section 20680(a) of Title 27, which states in part: Except as provided in ¶(b), (f) and § 20690, the owners or operators of all municipal solid waste landfill units shall cover disposed solid waste with a minimum of six inches of compacted earthen material at the end of each operating day, or at more frequent intervals if necessary, to control vectors, fires, odors, blowing litter, and scavenging? 2. The Discharger has failed to place and/or maintain an adequate layer of daily or intermediate cover at two separate locations in LF-3 during the wet season. As outlined in Table 15 of Monitoring and Reporting Program R5-2021-0060, the wet season runs from 1 October through 30 April each year. Areas of exposed gray ash waste were present outside the active face were only daily or intermediate cover soil should be located during the wet season.

2. No liquid was detected in the East Pond LD and lysimeter during all of 2020 and through May 2021. However, on 21 June 2021 liquid was detected in the East Pond LD and 750-gallons of liquid was removed. Three days later on 24 June 2021, liquid was detected again in the East Pond LD and this time in the East Pond?s Lysimeter as well. As a result, 15-gallons of liquid was removed from the East Pond lysimeter and anther 750-gallons of liquid was removed from the East Pond LD. Water Board staff was notified of the detection of liquid in the East Pond LD. However, even though the Discharger confirmed, as noted in the 2021 Semi annual Report, that the liquid observed in the East Pond LD and lysimeter was wastewater, the required Response Action Plan was not submitted within 30-days of the occurrence in violation of Section A.2 of Attachment 2 of the General Order, which states in part: ? If the liquid is confirmed to be wastewater, the Discharger must submit a Response Action Plan within 30 days for review and approval by the Regional Water Board. In a follow-up September 2021 email, the Discharger states that additional liquid, beyond that noted above, was removed from the East Pond LD, that they have already identified the cause of the release, have repaired the liner, and that they will submit an East Compost Pond Geomembrane Repair CQA Report within two weeks. The Discharger also stated that the total volume of water removed from the East Pond LD and lysimeter will be noted in the semi-annual report, even though not all liquid measurement and removal events were recorded on the East Pond?s Pond Liquid Management log. |
