6 � � � � �.�' ? ��.�„�r �E��•tom: � �i" sr. s � Comments Continued: The following area of concern of the State Minimum Standards (SMS),Title 27, California Code of Regulations(CCR))was noted at the time of inspection: 27 CCR Section 20700 Intermediate Cover: . The standard requires that"(a)Compacted earthen material at least twelve (12) inches shall be placed on all surfaces of the fill where no additional solid waste will be deposited within 180 days to control vectors, fires, odors, blowing litter, and scavenging." Board staff and the LEA arrived at the landfill daily working area early in the morning and observed around a small area of the fill slope east of the work face some compacted refuse day lighting. The site supervisor stated that the refuse was exposed because of repeated drives over the surface by the scrapper that was transporting cover material from the burrow pit below. Additional cover was placed over the area before the completion of the inspection. Other than the above indicated area of concern,the landfill operations at the Foothill Landfill were good at the time of the inspection. The work face was of manageable size. The cover application from the previous day's operation was good. The work deck was clean and water was being sprayed over the deck and access roads before the start of the operation and throughout the period of the inspection. The site operation appeared to have adequate staffing and equipment. Litter control crews were picking up windblown litter around the landfill. All E-waste accepted for recycling was placed in containers. Most of the fill decks and slopes(Module I)appeared to be in good condition. Although, at the time of the inspection, it was difficult to see the conditions of the north facing fill slopes in Module I, as tall grass has grown over the area during the last rain season. The LEA will closely monitor the condition of the slopes, after the operator mows the grass in preparation for operation during the next rain season. Also,there was some grading and provisions for adequate drainage (in Module 1)that the LEA will continue to monitor. The site supervisor stated the areas sloping east in Module 1 are scheduled for grading work. Board staff and the LEA reviewed the disposal site and municipal solid waste landfill unit records. Records of the Log of Special Occurrences and some of Personnel Training were reviewed at the landfill. All other records were reviewed at the offices of the Safi Joaquin County Public Works Department, in Stockton. Board staff and the LEA also measured methane gas levels at three selected monitoring probes at the landfill. We also reviewed the operator's 1 st quarter 2008 monitoring results for all of the probes around the landfill. All monitoring results indicated that the methane levels were well within the regulatory limits.
