Mr. Lawrence Stefani October 7, 2003 Page 5 • On September 10, 2003, SCS was notified by the ADS of a BFS shutdown. Upon arrival, SCS observed the shutdown was attributed to a flame failure condition. Further troubleshooting determined the flare flame scanner was overheating/ malfunctioning. SCS adjusted the scanner tube assembly to decrease the detected overheating condition, reset necessary controls, restarted the BFS and verified proper operation. Also, on September 4, 12, 18 and 24, 2003, Best Environmental performed weekly flare stack emissions monitoring as required by the SJVUAPCD. In addition, on September 2, 2003, SCS performed monthly BFS Condensate Storage Tank Carbon Vent VOC breakthrough testing. Photo Ionization Detector (PID) results indicated that no VOC's were detected on the inlet and outlet of the carbon vent. Furthermore, on September 25, 2003, SCS performed quarterly Hydrogen Sulfide (112S) monitoring as required by the SJVUAPCD. Results of the testing indicated that 6 parts per million (ppm) H2S was detected. The next required monitoring event is scheduled to be performed by the month of December 2003. Finally, during the reporting period, the flare exit gas temperature was observed to remain above the SJVUAPCD 1400 degree Fahrenheit prescribed operating criteria. The lowest flare exit gas temperature observed by SCS during our site visits was approximately 1430 degrees Fahrenheit. All other operating parameters remained within acceptable operating limits. Site Surface Observation Visual observation of the landfill surface along the extent of the extraction system is also performed on a monthly basis. Observations for erosion, surface cracks (that might allow LFG to escape or promote air intrusion) and settlement around wells,laterals and main pipelines are conducted. During this reporting period, no settlement that might adversely impact (e.g., allow condensate accumulation such that a complete blockage could occur) the LFG collection system operation was observed. Standard Provisions This report addresses conditions at the subject site during the reporting period only. Accordingly, we assume no responsibility for any changes that may occur subsequent to our monitoring which could affect the quantity of LFG at the subject site or adjacent properties. The client is responsible for ensuring that SCS and on-site personnel are the only parties designated to operate and adjust the LFG systems.
