A significant amount of windblown waste was observed along and just beyond the eastern downslope extent of FA2/Phase 6, outside the completed, lined extent of Fill Area 2. Violation 1. 1. Prohibition 4 of the WDRs states; The discharge of wastes outside of a Unit or portions of a Unit specifically designed for their containment is prohibited. 2. Prohibition 6 of the WDRs states; The discharge of solid or liquid waste or leachate to surface waters, surface water drainage courses, or groundwater is prohibited. |

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 |

Order Conditions |
Standard Provisions and Reporting Requirements, December 2015, Section D.1 states: ?The Discharger is responsible for accurate characterization of wastes, including a determination of whether or not wastes will be compatible with containment features and other wastes at the waste management unit and whether or not the wastes are required to be managed as a hazardous waste [Title 27, § 20200(c)] or designated waste [Title 27, § 20210].? Prohibitions 1 of the WDRs states in part: ?The discharge of ?hazardous waste? or ?designated waste? into Fill Area 1, Unit 1, a Class III landfill WMU is prohibited except Fill Area 1, Unit 1 may accept asbestos in the designated area shown in Attachment C. ?? Prohibitions 2 of the WDRs states: ?The discharge of ?hazardous waste? into any Class II WMU is prohibited except for asbestos in designated areas documented by the Discharger. For the purposes of this Order, the term ?hazardous waste? is as defined in California Code of Regulations, Title 23, section 2510 et seq. Any violation of Prohibitions 1 and 2 shall be reported in accordance with the Discharger?s MRP R5-2016-0042? Facility Specification C.2 of the WDRs states: ?The Discharger shall immediately remove and relocate any hazardous wastes discharged at this facility in violation of this Order. For the unauthorized discharge of hazardous waste (e.g., waste that has not been granted a variance from hazardous waste management requirements pursuant to Health and Safety Code section 25143), the Discharger upon discovery shall immediately notify Central Valley Water Board staff and DTSC of any violations and provide a schedule for the hazardous waste?s removal.? Standard Provisions and Reporting Requirements, December 2015, Section K.5 states: ?The fact that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with this Order shall not be regarded as a defense for the Discharger?s violations of this Order.? |
