1.3 STANDARD OBSERVATIONS Landfill personnel perform weekly inspections of the facility. As provided in Appendix A, these observations include identification of evidence of liquids entering or leaving the landfill, indications of ponding on the landfill or erosion of the landfill cover soils, and identification of strong landfill gas odors. No unusual conditions were identified during the first quarter 2010 monitoring period, (see signed "Certification Statement"located inside cover page, after the Table of Contents in this report). In addition to Forward's inspections,the San Joaquin County Environmental Health Department(CEHD)performed monthly inspections at the facility on January 29, February 26, and March 17, 2010. During the February 26 and March 17, 2010 inspections the CEHD issued a Notice of Violation (NOV) for explosive gas control as a result of methane concentrations exceeding 5% at the boundary at perimeter gas probe GP-11 for the shallow and/or intermediate depth probes. Forward continues to make adjustments to the landfill gas extraction system to correct the problem. No other NOVs were noted during the first quarter 2010 monitoring period. Completed inspection forms are presented in Appendix A. 1.4 SOLID WASTE MONITORING According to the Forward Landfill Operations Manager, Forward Landfill received a total of 229,741 tons of solid waste during the first quarter 2010(Appendix A). Figure 1-2 shows the approximate location of waste placement during the monitoring period. The following types of waste were received: Non-hazardous solid waste—225,146 tons Asbestos— 796 tons Sewage and wastewater sludge—3,799 tons 1.5 LANDFILL GAS MONITORING As previously discussed in Section 1.3,perimeter soil-pore gas probe GP-11 exceeded the regulatory limit of 5 percent during the first quarter 2010. Forward continues to adjust the landfill gas extraction system to correct the problem. In response to elevated methane concentrations measured in these probes, and in accordance with California Code of Regulations Title 27, Section 20937, Forward continues to install additional landfill gas extraction wells (as needed), and makes regular adjustments to the landfill gas extraction system to optimize efficiency of the landfill gas extraction system. Furthermore, in accordance with CCR Title 27, Section 20937(a)(1), methane monitors are installed in all buildings at the site to protect public health and safety and the environment. During the first quarter 2010,no methane was detected in any of the facilities buildings. A copy of the landfill gas monitoring probe data is provided in Appendix A.
