Box 1788 Sanford, Flodda 32772-1788 Attention: Mr. Robert G. Herman, Assistant Director Su~ect: Proposal for 2003 Extra Gas Monitoring Services In Accordance with Flodda Department of Environmental Protection Letter Dated January 13, 2003 for Art Lane Landfill, Sanford, Flodda Gentlemen: As requested, Ardaman & Associates, Inc. (Ardaman) appreciates the opportunity to present this proposal for performing extra 2003 gas monitoring services as explained in an Ardaman January 22, 2003 letter to the City in response to Florida Department of Environmental Protection (FDEP) letter dated January 13, 2003 for the Art Lane Landfill. This proposal provides the extra gas monitoring services beyond the permit required four quarterly gas probe monitoring events reports identified in the 2003 permit monitoring services proposal dated January 10, 2003. The existing gas monitoring network includes 4 probes (LFG*I through LFG-4). Figure 1 shows the approximate monitoring network locations. These flush mounted probes are located near MW- 5, MW-6, MW-8 and MW~9. Four quarterly gas probe monitoring and reporting events were proposed as part of the 2003 permit monitoring services proposal dated January 10, 2003. Extra Gas Monitoring Program In the January 22, 2003 letter to the City, the following extra gas monitoring program was proposed at this facility: (1) install two additional four-inch diameter PVC vertical gas vents ten feet northwest and ten feet southeast of gas probe LFG-1. The vents will be approximately 12 feet in length including a 2-foot long tailpipe with 4 feet of perforated pipe connected to the tailpipe. The pipe will penetrate the GCL layer and a patch will be installed at each vent. The 12.25-inch diameter borehole will be filled with non-calcareous gravel surrounding the pipe. The solid pipe will extend 4 feet above grade and be finished with a 180-degree elbow fitting. (2) Perform additional gas probe readings on a weekly basis at gas probes LFG-1 and LFG-2 until the gas vents are installed. If another reading exceeds 75% LEL at LFG-2, then two four-inch 8008 S Orange Avenue (32809) Post Office Box 593003, Orlando. Florida 328593003 Phone f407i 855-3860 FAX i407) 859 8121 Art Lane Yard Trash Landfill File Number 02-199A -2- diameter PVC vertical gas vents will be installed ten feet northwest and ten feet southeast of gas probe LFG-2. (3) At gas probes LFG-2 (if gas vents are installed) and at LFG-1, continue additional gas probe readings on a monthly basis for the first quarter after vent installation. The cost estimate for the extra 2003 gas monitoring work is provided in Table 1. The monthly invoices will be based on work expended and units performed in accordance with the existing contract fee schedule. The maximum amount not to be exceeded without further written authorization is $10,412.20. The gas vents at LFG-2 will not be installed if the extra gas monitoring results indicate LEL values of less than 75%. If the proposal meets with your approval, please have the appropriate person sign the enclosed proposal acceptance forms and return one for our records. The work will be in accordance with existing contract 98-99~27. Please do not hesitate to contact us should you have questions or need additional information. We appreciate the opportunity to submit this proposal for these ground water related services. Very truly yours, Herbert G. Stangland, Jr.,"~.~.
