Mr. Don Litchfield <br /> October 8, 2010 <br /> Page 6 <br /> On September 30, 2010, SCS removed and cleaned the pilot tube and fireye, restoring proper <br /> operation. <br /> Additionally,on September 1, 7, 14, 20 and 29, 2010, SCS performed monitoring of the <br /> Greenhouse Gas Test Port as required by the EPA. These results are shown in Table 6 and were <br /> also sent to the EIL Database as required. <br /> Additionally,the flare remained below its maximum allowable BTU throughput during the <br /> reporting period. <br /> Finally, during the reporting period,the flare exit gas temperature was observed to remain above <br /> the Title V required temperature of 1475 degree Fahrenheit prescribed operating criteria,which is <br /> 50 degrees below the last source test performed,based on the three hour time weighted average. <br /> The lowest flare exit gas temperature observed by SCS during our site visits was approximately <br /> 1567 degrees Fahrenheit. All other operating parameters remained within acceptable operating <br /> limits. <br /> SITE SURFACE OBSERVATION <br /> Visual observation of the landfill surface along the extent of the extraction system is also <br /> performed on a monthly basis. Observations for erosion, surface cracks (that might allow LFG to <br /> escape or promote air intrusion) and settlement around wells, laterals and main pipelines are <br /> conducted. <br /> During this reporting period,no settlement that might adversely impact(e.g., allow condensate <br /> accumulation such that a complete blockage could occur)the LFG collection system operation <br /> was observed,with the exception of the previously mentioned areas of the side slopes which are <br /> in need of repair. <br /> STANDARD PROVISIONS <br /> This report addresses conditions at the subject site during the reporting period only. <br /> Accordingly,we assume no responsibility for any changes that may occur subsequent to our <br /> monitoring which could affect the quantity of LFG at the subject site or adjacent properties. The <br /> client is responsible for ensuring that SCS and on-site personnel are the only parties designated to <br /> operate and adjust the LFG systems. <br /> Should you have any questions, do not hesitate to contact or either of the undersigned. <br /> Very truly yours, <br />
