(S+G) is pleased to present this report concerning the operation and maintenance (O&M) of the Avery County Closed MSW Landfill (Permit No. 06-01) Landfill Gas Collection and Control System (LFGCCS) and monitoring of the on- and off-site landfill gas probes for the July 2015 monitoring period. Mr. Don Misenheimer with S+G performed the site visit on July 23, 2015. Site visit details are provided below. CURRENT STATUS S+G previously identified the following items to be addressed for the LFGCCS to operate as designed: 1. LFGCCS System: An expansion of the LFGCCS system, as proposed in the Annual Landfill Gas Monitoring Report1, was previously approved2 by the division of Waste Management. Phase One of the expansion project has been completed. S+G is reviewing the data collected to evaluate the improvements for effectiveness. A summary of this evaluation has been submitted to the division under separate cover including recommendations for additional work. LFG EXTRACTION WELL MONITORING PROGRAM Monthly monitoring of the LFGCCS will continue and shall include the following items:  CH4, O2, CO2, and pressure monitoring at each extraction well head;  CH4, O2, CO2, and pressure monitoring at the flare station; and  Adjustment of the LFGCCS to balance recovery and ensure safe system operation. 1 Annual Landfill Gas Monitoring Report, Closed Avery County MSW Landfill. Submitted by Smith Gardner, Inc., November 2012. 2 Approval response letter, Closed Avery County MSW Landfill (Annual Landfill Gas Monitoring Report). Sent by Jaclynne Drummond, Solid Waste Section, November 15, 2012. Ms. Drummond August 20, 2015 Page 2 of 3 The County will maintain this LFGCCS and will continue to evaluate the effectiveness of increased LFG recovery from the waste mass in alleviating off-site LFG migration. Results from monthly monitoring events will be reported in accordance with the approved LFG Monitoring Plan. LFG EXTRACTION WELL MONITORING ACTIVITIES S+G personnel performed the flare station and well field monitoring on July 23, 2015. Initial measurements indicated there was approximately 24 inches of available vacuum average throughout the well field, ranging from approximately 24 to 25 inches of available vacuum at each of the LFG wells across the well field. The results from this event are summarized below. Recommended actions are underlined. Well field data and flare station data are provided in the attached Table 1. LFG Extraction Well Field  W-1 through W-10: S+G performed methane (CH4), oxygen (O2), carbon dioxide (CO2), and pressure monitoring. No adjustments were made to the extraction well heads during this monitoring event.  Orifice Plates: S+G continues to evaluate orifice plate sizes at wells W5, W7, W9, and W10 during each site visit. As LFG flow potential at these locations remains stable, the correct orifice plate sizes are currently installed. Flare Station  Condensate Tank: The condensate tank was observed during this site visit; the liquid was at an acceptable level. S+G will continue to monitor the liquid level of the condensate tank.  Filter Tank: The filter tank was observed during the July 2015 site visit and the liquid level was found to be at an acceptable level. S+G will continue to monitor the liquid level of the filter tank.  Flare operation: The flare was off when S+G arrived on-site, however the spark was working. The flare was able to be ignited prior to S+G leaving the site. S+G will continue to adjust the system to optimize gas flow and quality.
