Mr. Dan Johnson February 11, 2009 Page 3 On January 22, 2009, as requested by site personnel, SCS performed testing of LFG Evaluation Monitoring Probe No. SG -11 (see Table 1). Results indicted that methane gas concentrations of up to 6.7 percent by volume were detected. Note that Probe No. SG -11 has exhibited fluctuating levels of methane gas and is intended for on-site subsurface evaluation purposes and is not a regulatory compliance location. Additionally, as required semiannually by Waste Discharge Requirements R5-01-176, soil pore gas samples were collected on January 22, 2009, from designated perimeter monitoring probes and analyzed for volatile organic compounds (VOC's) utilizing the Modified Method TO -14A. The results of these analyses will be submitted separately in our First Quarter 2009 Perimeter Probe Monitoring report. The next required testing shall be performed during the third quarter 2009. ON-SITE INTERIOR STRUCTURE TESTING In accordance with the approved testing schedule, the interiors of on-site structures are to be tested at a minimum, on a quarterly basis. As previously reported during October 2008, all on-site structures (i.e., scalehouse, maintenance building, manager's residence, and south residence) were tested for the presence of methane gas. In each structure, random selected locations (i.e., electrical outlets and junction boxes, conduits, drains, floor cracks, etc.) were tested. Test results indicated no methane gas in excess of 1.25 percent by volume was detected at any location tested. SCS is scheduled to perform first quarter monitoring of 2009 (January through March) of the interiors of on-site structures by the end of the month of March 2009. LFG EXTRACTION WELL TESTING System adjustments are required whenever an extraction well exhibits an unacceptable change in pressure, 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 accessible LFG interior and perimeter extraction wells performed on January 14 and 22, 2009, (see Table 2) indicated that most extraction wells exhibited an under pull condition. SCS will continue to adjust (utilizing new county adjustment protocols) accessible LFG extraction wells to maintain operational criteria. D
