44. The operator l shall design and construct the landfill in accordance with all federal and State requirements relative to seismic safety. The final design shall be reviewed by the RWQCB (pri~r to issuance of revised Waste Discharge Requirements) and the LEA (as part of the application for a revised Solid Waste Facilities Permit). RWQCB and LEA approvals shall signify that the proposed design meets all of the applicable seismic safety requirements.i To protect on-site personnel, ensure the integrity of the landfill, and minimize any disruption to landfill operations in the event of a major earthquake, the operator shall update the Earthquake Response Plan (part of the site's Emergency Response PIan currently in effect) to include post-earthquake inspection to evaluate any damage that may have occurred, ensure the integrity of the landfill containment systems, and make the landfill operational as soon as possible. HYDROLOGY/WA~FER QUALITY 45. The operator shall comply with the following RWQCB requirements based upon the project description: (a) Prepare a Leachate Monitoring Plan. Monitoring procedures shall address the amount of leachate generated, its chemical composition, and the depth of leachate buildtip on the liner. Leachate monitoring activities shall comply with the site's Wastd Discharge Requirements, and applicable sections of CCR Titles 14 and 23. (b) Prepare and submit a groundwater monitoring plan to the RWQCB as part of the Report of Waste Discharge, prior to issuance of the Waste Discharge Requi~'ements. Groundwater monitoring shall be conducted using background and compliance wells. Monitoring well placement shall take into consideration the ldcal variability in geologic materials that influence groundwater flow as indicated by various conceptual groundwater flow models identified by RUST EnvirOnment & Infrastructure (1994). (c) Prepare and submit a vadose zone monitoring plan to the RWQCB as part of the Report of Waste Discharge, prior to the issuance of the Waste Discharge Requkements. Vadose zone monitoring shall be conducted in accordance with CCR !Title 23, Section 2550.7(d). Liquids collected in the systems shall be monitr~red periodically. The operator shall remove or remediate any detected conta~ninants pursuant to CCR Title 23, Section 2550.11. (d) Implement appropriate corrective measures in the event of leachate migration pursuOnt to Section 2550.10 of CCR Title 23 shall be implemented by the operator, subject to approval and oversight by the RWQCB, Central Valley Regidn. (e) Submit a copy of the annual report prepared for the appropriate RWQCB to the Planning Department. 46. The landfill shall be designed and constructed to control drainage and erosion in accordance with the facility Waste Discharge Requirements including surface water run- 16-B Final Altamont Settlement - Exhibit B
