1143592 05/13/2025 Order Conditions 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. Violation None Inspection Altamont/Resource Recovery Class II & III Landfills,Class II Surface Impoundment 407660 R5-2016-0042 Y
1143238 03/11/2025 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 None Report Altamont/Resource Recovery Class II & III Landfills,Class II Surface Impoundment 407660 R5-2016-0042 Y
