Comments Continued: Board staff and the LEA started the inspection early in the morning, arriving at the work face at about 6:45 a. in. Disposal operation was being conducted in Module IV area of the landfill. We observed that the operator had used geo-synthetic tarps as the Alternative Daily Cover(ADC)over the refuse at the end of the previous day's operation. The application of the ADC cover was good and the compaction of the refuse, after the tarps were removed, was also good. The work deck was clean. We monitored the preparation for the daily landfill operation. The water truck started spraying the access roads and work deck areas from the start of the operation for effective dust control. The effort continued throughout the period of the inspection. Site personnel removed the tarps,placed cones to direct the truck traffic, and prepared the equipment for the operation. Disposal operations started a bit after 7:00 a.m. The size of the disposal work face was small and manageable. The site litter control program appears to be effective. All areas around the landfill and access roads were free of litter. All fill slopes and decks were in good condition. The site operations supervisor stated that further work on the decks and slopes is planned, as they get ready for operation during the upcoming winter season. Board staff and the LEA reviewed the disposal site and municipal solid waste landfill unit records, some at the site and others at the offices of the County Department of Public Works in the City of Stockton. All of the required records were in place, as approved by the LEA. Board staff and the LEA took methane gas level readings(using the LEA's LandTec GEM-2000) on multi-depth Probes SG-1 and SG-2. The results we obtained were all within the regulatory limits (highest readings of 0.2%). We also reviewed the results of the operator's quarterly (1 st and 2nd 2008) property boundary monitoring program, and the results indicated that methane levels were non-detect(0.00%). Other Notes of Inspection: New Landfill Gas Regulations: We encourage the LEA to work with the owner and operator of the landfill and the appropriate Board staff to complete the submittals, reviews, approvals, and installations of the required LFG monitoring and Control Systems by the established due dates.
