slopes will be directed to cant'runoff to areas where erosion and sedimentation can be controlled. Truck beds will be hosed down to reduce soil spillage on paved roads and wind- blown dust. Relocation of Littlejohns Creek could lessen the sedimentation potential to the creek. Completed cells will be stabilized by the planting and maintenance of drought-resistant grasses. This will inhibit wind and water erosion and maximize the fertility of the soil in order to facilitate revegetation. " Temporary plantings,geofabric drapes,and erosion-preventing diversions of surface water will be constructed as appropriate on temporary slopes. Regular operational and post-closure monitoring of erosion control structures and"plantings will be done for a minimum of five years. n. 69 Forward 4993(B.6) Assessment of groundwater levels In monitoring wells shall be initiated within 24 hours following an earthquake event having a Modified Mercalli Intensity of V or greater at the • landfill. This will allow the water level database to be adjusted or seismic variations. In the event that anomalous water level changes are noted, a series of water quality sampling and testing events shall be initiated by the applicant in cooeination with the RWQCB to detect an changes In water quality that may signify subsurface adjustments in landfill cells. o. 60 Forward 4993(B.6) Benchmarks shall be established(these could utilize monitoring well top of casing elevations), which will allow for determinations of settlemenrl oonsolidation of rill materials in closed sections of the landfill on an annual basis and following significant selsmlc events (Modified Mercalll Scale of V or above). In the event that changes are noted,the cause should be determined as should the effect on leachate-collection and recovery systems. Repair liners and LCRS as necessary. In addition,remedial spading should be accomplished to restore the original cap's function to repel water and direct surface runoff p. 66 Austin 2000(F9.a) A 4.3-acre detention basin wilt be constructed In the southwest comer of the project site,as depicted on the project plans(Beck 9993). q. 81 (1.4) Proposed as Part of the Project: If leachate is delivered to the City of Stockton Regional Wastewater Control Facility,the project sponsor will provide for independently corroborated test results to the City to demonstrate the chemical composition of the leachate extracted from the proposed consolidated landfill project. Monitoring and testing of landfill-generated leachate will meet the requirements of the City of Stockton Wastewater Ordinance and the City Municipal Utilities Department. If leachate quality Is not acceptable for disposal at the Regional Wastewater Control Facility, the project sponsor will either have the leachate collected and disposed off-site by a licensed Treatment and Disposal Facility,or will develop on-site leachate processing that will result In treated leachate that is acceptable for disposal at the wastewater treatment plant or acceptable to regulatory agencies for on-site use. The design and operation of any on-site leachate processing that Is implemented will comply with all applicable taws and regulations. San Joaquin County UP-00-7,ER-00-21Forward,Inc.
