Landfill gas shall be monitored and controlled as required by Rule , F.A.C. b. Landfill gas shall be monitored to demonstrate compliance with the criteria established in Rule (1)(a), F.A.C., (less than 25% of the lower explosive limit (LEL) for combustible gases in on-site and offsite structures, and less than 100% of the LEL for combustible gases in perimeter gas probes at the property boundary). Landfill gas monitoring results shall be reported as a percent of the LEL, calibrated to methane. c. The results of the quarterly monitoring required by Rule (2)(c), F.A.C., shall be submitted to the Department by the following dates: Measured During Report Submitted By Quarter 1 April 15 th of each year Quarter 2 July 15 th of each year Quarter 3 October 15 th of each year Quarter 4 January 15 th of each Page 29 of 32.

33 SPECIFIC CONDITIONS: PART F Landfill Gas Management 3. Gas Monitoring Locations. The landfill gas monitoring locations are described in Section O ( Landfill Gas Monitoring and Management System ), prepared by SCS, revised September 3, 2004 [Ref. SC#A.2.b.(2)]. The ambient gas monitoring points and perimeter gas monitoring probes are located on Figure 2-1 entitled Location of Monitoring Wells Used in Anova Analyses, prepared by SCS, received March 29, 2005 (attached), and shall be sampled at least quarterly for concentrations of combustible gases determined as a percent of the LEL calibrated to methane, as described in Rule (2), F.A.C. Ambient Monitoring Points: Storage Building Leachate Lift Station (sump) RC Aircraft Club Cell Phone Tower Facilities Soil Monitoring Probes: GW-1 (landfill perimeter-southwest) GW-2 (landfill perimeter-west) GW-3 (landfill perimeter-west) GW-4 (landfill perimeter-west) GW-5 (landfill perimeter-west) GW-6 (landfill perimeter-west) GW-7 (landfill perimeter-northwest) GW-8 (landfill perimeter-northwest) GW-9 (landfill perimeter-north) GW-10 (landfill perimeter-north) GW-11 (landfill perimeter-northeast) GW-12 (landfill perimeter-northeast) GW-13 (landfill perimeter-east) GW-14 (landfill perimeter-east) GW-15 (landfill perimeter-southeast) GW-16 (landfill perimeter-southeast) Location See Figure 2-1 (attached) Location See Figure 2-1 (attached) Soil monitoring probes are to be clearly labeled and easily visible at all times. 4. Gas Remediation. If the results of gas monitoring show that combustible gas concentrations exceed 25% of the LEL calibrated to methane in structures or 100% of the LEL calibrated to methane at the property boundary, the permittee shall immediately take all necessary steps to ensure protection of human health and notify the Department. Within 7 days of detection, a gas remediation plan detailing the nature and extent of the problem and the proposed remedy shall be submitted to the Department for approval. The remedy shall be completed within 60 days of detection unless otherwise approved by the Department. Page 30 of 32.

34 SPECIFIC CONDITIONS: PART G Closure and Long-Term Care Requirements 1. Closure Permit Requirements.
