The MGM estimated yearly landfill gas production over the productive <br />life of the Corral Hollow Sanitary Landfill. The estimated gas <br />production and recovery curves are shown in Figure 1. The estimated <br />peak gas production is 670,000 cf/day in 1995; approximately <br />500,000 cf/day may be recoverable (75 percent). The current gas <br />production capability is estimated to be 500,000 cf/day with <br />375,000 cf/day being recoverable. <br />GAS CONTROL <br />Recently enacted Calderon amendments to the Health and Safety Code <br />(HSC Section 41805.05) require that all landfill owners perform gas <br />and ambient air testing and report the results to their local Air <br />Pollution Control Officer (APCO). In addition, the Disposal Site <br />Testing Guidelines (Guidelines) approved by the Air Resources Board <br />(ARB) on December 18, 1986, require that the Air Solid Waste Assess- <br />ment Test (ASWAT) report include a determination of whether landfill <br />gas is migrating off-site. To fulfill the Guideline requirements, an <br />extensive testing program has been proposed for the Corral Hollow <br />site. <br />Approximate locations for the proposed gas probes and wells for the <br />testing program are shown on Drawing 1. Drawing 3 shows a detail of <br />the probe/well. Gas wells will be monitored for the testing program <br />as described in the Air Quality Solid Waste Assessment Test (ASWAT) <br />proposal. When the Air Quality SWAT is completed, the gas wells will <br />be destroyed. The gas probes will remain intact and be monitored <br />annually through the postclosure period for combustible gas at the <br />landfill boundary. Appropriate remedial action will be developed to <br />eliminate safety and environmental problems if gas migrates off site. <br />PJ9 9390310.00D 7 <br />Ci rnn <br />
