Order Conditions |
The concrete lined drainage channel that discharges runoff from the Receiving/ Processing Pad to the North Pad has been intentionally blocked to facilitate construction atop the North Pad. The blockage of this drainage channel could result in a direct discharge of compost leachate to surface water. |

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. |

Order Conditions |
Construction of Module 6 of the Class II Waste Management Unit (WMU) has begun without Central Valley Water Board staff approval. WDRs/General Construction Specifications D.1 1. The Discharger shall submit for review and approval prior to construction, design plans and specifications for new Units and modules of existing Units, that include the following: a. A Construction Quality Assurance Plan meeting the requirements of §20324 of Title 27; and b. A geotechnical evaluation of the area soils, evaluating their use as the base layer; and c. An unsaturated zone monitoring system, which is demonstrated to remain effective throughout the active life, closure, and post-closure maintenance periods of the Unit, which shall be installed beneath the composite liner system in accordance with §20415(d) of Title 27. |

The erosion noted in Violation 4 above has caused significant sedimentation to occur in the storm water V ditch that run along the western side of Module 1, 2, and 10, as well as within the northern storm water sedimentation basin. The degree of sedimentation observed will prevent these storm water control features from operating as designed during future rain events. |
