Mr. Dan Johnson February 11, 2009 Page 4 On January 22, 2009, SCS increased the extraction rates at LFG Extraction Wells GX-06 and GX-08 in attempts to help control the above mentioned elevated methane gas concentrations detected at the LFG Monitoring Probes. Finally, during this reporting period, temperatures at LFG extraction wells were monitored and observed to range from 58 to 115 degrees Fahrenheit (see Table 2). These temperatures are considered to be in the normal to upper range for anaerobic decomposition. SCS will continue to test LFG temperatures at each extraction well on a monthly basis in order to develop a database. This additional information should provide a better understanding of subsurface conditions at the site. LFG COLLECTION SYSTEM Visual observation of the LFG collection system is conducted monthly. During this visit, observations are made to ensure no pipe breakages have occurred and condensate drain sumps remain functional. Minor repairs are completed as required. Finally, SCS routinely conducts a pressure drop survey, Test Port Nos. MP -4 through MP -6 (i.e., measurement of main pipeline pressure at various points throughout the LFG collection system). The results of this survey indicated that no major restrictions within the LFG collection system currently exist and all accessible extraction wells are receiving adequate vacuum (see Table 4). LFG BLOWER/FLARE STATION (BFS) Visual observation and testing of the LFG BFS is conducted monthly or when SCS is on site for other monitoring. During these visits, operating parameters are monitored and mechanical and electrical components are checked for workability. Throughout the reporting period, the BFS was programmed to operate continuously. BFS data is shown in Tables 3 and 4 (a completed field inspection checklist is provided with this report). During this reporting period, SCS understands that the BFS operated as programmed with the exception of the following scheduled shutdown: • On January 14, 2009, SCS shut down the flare to switch operation of the blowers. Upon completion of this work the BFS was restarted and proper operation verified. On January 14, 2009, SCS performed monthly Carbon Monoxide (CO) testing as directed by the County. Results indicated that 15 parts per million CO was detected. The next required testing is scheduled to be performed during the month of February 2009. Finally, during system operation the flare exit gas temperature was observed to remain above the system shutdown temperature of 200 degrees Fahrenheit. During this reporting period, the lowest flare exit gas temperature observed was 369 degrees Fahrenheit. All other operating parameters remained within acceptable limits. u i� 1 u r� r u u
