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.? |

Violation 1 ? Compost and compost leachate were observed south off the South Pad at multiple locations along the southern limit of the South Pad. 1. Prohibition 1 of the Compost General Order states: Any feedstock, additive, amendment, or compost (active, curing, or final product) stored, processed, or composted outside of the designated composting operation areas, as those boundaries are specified in an NOI and/or a technical report, and approved by the Regional Water Board, is prohibited. 2.

Order Conditions |
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. |

Discharge of waste outside the Facility?s Class III landfills to the unsaturated zone and groundwater beneath the Facility and beyond the Point of Compliance. WDRs Prohibitions A.2, A.8, and A.9, and Facility Specifications C.7, and Detection Monitoring Specifications F.6. Current Status ? ? VOCs are detected outside the units both in groundwater and landfill gas. ? No corrective action has been initiated to address the groundwater impacts. ? The previously landfill gas system has be covered over by the unpermitted placement of soil removed from the Module 6 project. ? The Discharger is not in compliance with the existing WDRs, and Title 27. Section 20430(j) of Title 27 states: RWQCB-Initiated CAP Changes -Any time the RWQCB determines that the corrective action program does not satisfy the requirements of this section, the discharger shall, within 90 days of receiving written notification of such determination by the RWQCB, submit an amended report of waste discharge to make appropriate changes to the program. |
