Michael Carroll, PE <br />Senior Civil Engineer <br />SUBJECT: LANDFILL GAS MONITORING AT NORTH COUNTY RECYCLING <br />CENTER AND SANITARY LANDFILL <br />On May 23, 2002, Solid Waste Division staff monitored for landfill gas migration at the <br />North County Recycling Center and Sanitary Landfill. Results from the Second Quarter 2002 <br />Monitoring Event show that all probes and structures are free of methane (Figure 1). <br />PVC pipes with caps were monitored for methane in accordance with the approved monitoring <br />plan. The pipes are open at the bottom, and are approximately two feet deep. The County used <br />a Landtec Gem 500 landfill gas instrument to perform the monitoring. This instrument was <br />calibrated by County staff prior to the monitoring event. <br />If you have any questions, please contact me at 468-3066. <br />MC:DJ:kf <br />N:\INorth County\Gas Monitoring\2nd2002.wpd <br />Attachment <br />Gino Yekta <br />California Integrated Waste Management Board <br />1001 "I" Street <br />Sacramento, California 95812-4025 <br />LA 63229 <br />
