Mr. Don Litchfield <br /> October 8, 2010 <br /> Page 5 <br /> located at LFG Extraction Well Nos. DEW-92,FOFU05-01,FOFU05-02,FUFO05-03, <br /> FOFU05-13 and the LFG pipeline between GP-25 and TP-10,restoring operations and <br /> subsequently reducing slightly elevated oxygen concentrations observed at the LFG BFS. <br /> Also on September 14, 2010, SCS temporarily repaired the age deteriorated control valves <br /> located at LFG Extraction Well Nos. DEW-33 and DEW-.4, resting normal operation. <br /> Finally, SCS routinely conducts a pressure drop survey(i.e., measurement of main pipeline <br /> pressure at various points throughout the LFG collection system)and an inspection of the <br /> Condensate Sump liquid handling systems. The results of this survey and inspection indicated <br /> that no major restrictions within the LFG collection system currently exist. All accessible <br /> extraction wells are receiving adequate vacuum and the condensate handling system remains <br /> functional (Tables 2 and the attached sump counter information). <br /> LFG BLOWER/FLARE STATION ( BFS) <br /> Visual observations and testing of the LFG BFS was conducted on September 1, 3, 7, 14, 17, 18, <br /> 20, 21, 23, 28,29 and 30, 2010. During these visits, operating parameters are monitored and <br /> mechanical and electrical components are checked for workability. Throughout the reporting <br /> period,the BFS was set to operate continuously. BFS data is shown in Table 3,4 and 5. SCS <br /> understands the BFS operated as programmed throughout the reporting period,with the <br /> exceptions noted below. <br /> • On September 1, 6, 27, 29 and 30, 2010, SCS was notified that the LFG BFS had <br /> shutdown attributed to a pre-programmed ultraviolet system shutdown. SCS reset <br /> necessary controls,restarted the BFS and verified normal operation. <br /> • On September 23,2010, SCS responded to a Automatic Dialer System notification of a <br /> BFS Alarm. Upon arrival, SCS observed that both LFG Flares, FL-100 and FL-150,were <br /> in operation. SCS understands that others were on site performing calibration to the LFG <br /> flowmeters. SCS shutdown LFG Flare FL-150 and left FL-100 in operation. SCS <br /> verified normal operation prior to departure. <br /> In July 2010, SCS performed additional quarterly Hydrogen Sulfide (112 S)monitoring as <br /> required by the SJVAPCD. Dragger tube results indicated that 20 and 25 parts per million (ppm) <br /> H2S were detected, respectively. The next required quarterly testing is scheduled to be <br /> performed by the month of December 2010. <br /> On September 1, 2010, SCS changed the air regulator for the flare inlet actuator valve, restoring <br /> regular operation. <br /> Also, on September 23, 2010, SCS performed monthly BFS Condensate Storage Tank Carbon <br /> Vent VOC breakthrough testing. Photo Ionization Detector(PID)results indicated that 3 parts <br /> per million (ppm) VOC's were detected at the inlet and outlet of the carbon vent. <br />
