California Integrated Waste Management Board Disposal Facility Inspection Report ( ) SWIS Facility File Number(99-xx-9999) Inspection Date Program Code 39-AA-0004 12/9/2009 CIWMB Periodic Time In Time Out Inspection Time Facility Name Received By Foothill Sanitary Landfill Sent by e-mail to Jaime Perez-Op. Manager Facility Location Owner Name 6484 North Waverly Road Inspector Also Present(Name) Tadese Gebrehawariat 1M. Kith-LEA&J. Padilla- Landfill Manager THE ABOVE FACILITY WAS INSPECTED FOR COMPLIANCE WITH APPLICABLE SECTIONS OF THE DIVISION 30 OF THE PUBLIC RESOURCES CODE(PRC)AND TITLE 14 AND TITLE 27 CALIFORNIA CODE OF REGULATIONS(CCR) No Violations or Areas of Concern V A Regulations X 20680-Daily Cover Comments:This standard requires that"the owners or operators of all Municipal Solid Waste Landfill(MSWLF)units shall cover disposed solid waste with six inches of compacted earthen material at the end of each operating day,or at more frequent intervals if necessary,to control vectors,fires,odors,blowing litter,and scavenging...". "...The EA may also approve alternative cover materials of alternative thickness at MSWLF units,if the owner or operator demonstrates that the alternative material and thickness control vectors,fires,odors, blowing litter,and scavenging without presenting a threat to human health and the environment." Board staff and the LEA arrived at the site at 6:25 a.m.and after reporting to the landfill manager proceeded to the landfill work face to observe the cover application during the previous day's of operation. We observed that the refuse on the work face was not covered at the end of the operation on December 8,2009(see attached photos#1 and#2). The landfill manager stated that both compactors broke down and the refuse was not compacted enough to allow for safe application of the daily cover using the scrapper. The manager explained further that he made the decision not to apply the cover because it wouldn't have been safe to have the scrapper drive over the uncompacted refuse. Throughout the morning,the personnel worked to repair the compactors,and were able to get one of the compactors running. During the period of the inspection,they compacted the refuse to their specifications and were able to apply cover over most of the refuse. We observed the personnel stockpiling soil cover adjacent to the work face with the use of the scrapper. Additionally,there was an area just west of the work face,where refuse had been placed and was compacted but uncovered(see attached photo#3). The landfill manager stated that the placed refuse was Construction and Demolition(C&D)used for the construction of wet weather deck. However,Board staff informed the manager and LEA that the material is refuse not suitable for the construction of wet weather deck. Only crushed concrete and asphalt can be used for the construction of wet weather deck. The comapcted refuse shall be covered and the practice shall be discontinued. X 20932-Monitored Parameters Comments:Review of the owner/operator's Landfill Gas(LFG)Monitoring Program completed early October 2009 showed that not all monitoring probes installed at the facility were monitored for methane. The records showed that the owner/operator did not monitor the newly approved and installated probes during their third quarter 2009 monitoring program. Installation of twnety four monitoring probes around the landfill was completed in August 2009. The LEA had in previous inspection reports directed the owner/operator to monitor all probes around the landfill. Thus,the Ocotber 2009 monitoring program should have included information about methane gas levels in the newly constructed monitoring probes as well. The quarterly monitoring program at the landfill shall be on all approved and installed monitoring probes. Inspection Report Comments: Pursuant to the Public Resources Code(PRC),Section 43220,Board staff conducted an 18-month inspection at the Foothill Landfill with the LEA. -Other than the issues described above,the operations of the landfill were good at the time of the inspection. Early in the morning,the preparation for the daily operation was good. The work deck was fairly clean. Employees picked some windblown litter on the fill slopes of Module I. Bird control measures were started early in the day,and disposal operation started at 7:00 a.m. We observed employees directing the traffic on the work face and were monitoring the loads. -The white goods and universal waste recycling area was orderly. All area were free of windblown litter. Water truck was available for dust control measures,if needed. Fill slopes and decks were in good condition. The decks appeared to have been graded to drain. The flare was functional. -Board staff and the LEA reviewed the Log of Special Occurrences,load check records,and training records on-site and were up-to-date. We also reviewed the tonnage and traffic volume and quarterly gas monitoring records at the Solid Waste Division offices in the City of Stockton. The records indicated that the levels of the waste and traffic receipts were within the permitted limits. The gas monitoring records also showed that methane gas levels in the monitoring probes were within the regulatory limits(non-detect). Board staff and the LEA also measured methnae gas levels on three of the newly installed monitoring probes and obtained readings of 0.00%.
