Mr. Lawrence Stefani October 7, 2003 Page 3 SCS will perform initial startup/adjustments of the new LFG extraction wells to help decrease methane gas concentrations below the LEL, when construction activities are complete. The next quarterly monitoring event is scheduled to be performed by the month of December 2003, or as directed by the Client. LFG Extraction Well Testing System adjustments are required whenever an extraction well exhibits an unacceptable change in methane and/or oxygen gas concentration (which could be due to an overpull or underpull condition). Overpull occurs when the extraction rate of a particular extraction well exceeds that of the LFG generation rate within the radius of influence of the well. During this overpull condition, air can be drawn through the ground surface to the extraction well and then ultimately be injected into the flare. If an excessive overpull condition is allowed to continue for a long period, a significant drop in the methane gas content of the LFG and/or a subsurface landfill fire could occur. Underpull occurs when the extraction rate of a particular extraction well is less than the generation rate within the radius of influence of the well. This condition could result in off-site subsurface LFG migration and/or surface emissions. Results of monthly testing and adjusting of LFG extraction wells performed on September 2 and 25, 2003 (see Table 1) indicate that several extraction wells exhibited an overpull and/or underpull condition. These conditions are necessary to maintain operational criteria (e.g. maintain a minimum 1400 degrees Fahrenheit flare exit gas temperature) at the BFS and to help maintain methane gas concentrations at perimeter monitoring probes to below the LEL. SCS will continue to monitor and adjust all LFG extraction wells to minimize the amount of overpull while maintaining operational criteria. Finally, during this reporting period, temperatures at LFG extraction wells were monitored and observed to range from 82 to 116 degrees Fahrenheit (see Table 2). These temperatures are considered to be in the normal 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 Svstem Visual observation of the LFG collection system is conducted twice per month. During these visits, observations are made to ensure no pipe breakages have occurred and condensate drain sumps remain functional. Minor repairs are completed as required.
