Purpose According to, Emergency Regulations, Closure and Postclosure Maintenance Plan Adoption Procedures and Uniform Standards for Closure and Postclosure of Solid Waste Landfills, August 1989 by the California Waste Management Board, no gas with a concentration of methane exceeding 5% shall leave the perimeter of a landfill . Since some of the gas-monitoring wells installed during the first phase of the perimeter gas-monitoring system have shown migration of gas greatly exceeding this limit, additional wells are proposed to define the extent of migration in those areas. Data from these wells would be used to extend the landfill boundary past the edge of the area of migration. Scope of Work General During the installation of the perimeter-gas monitoring system, monitoring wells GM-10 and GM-11 showed concentrations of methane below detection limits. It is assumed that no additional wells are necessary in the vicinity of these wells at this time. Monitoring wells GM-12 and GM-13 showed concentrations of methane greatly exceeding the 5% limit. The methane appeared to increase i; with depth and in an easterly direction along Starlight Boulevard. Methane above the 5% limit was observed in GM-15 in the shallow probe. The concentration in the deep probe was below the detection limit (<0.2%) . ' ' It is our understanding that the property west of GM-15 might be developed in the near future. If this should be the case, then additional wells should be installed in the vicinity of GM-15 (Plate 1) , to accurate'y define the extent of contamination. If no development is to occur then only one shallow well will be proposed. 111 411 Mr. Ron Masingale ATTACHMENT A City of Redding C89. 11. 02 Department of Public Works July 6, 1990 760 Park Avenue Page 2 of 11 Redding, CA 96001 II Proposal for Services (continued) j, The scope of work below is divided into two "Tasks" the first task will be to further define the extent of landfill gas migration in the vicinity GM-12 and GM-13 , including one shallow well in the vicinity of GM-15. The second task will be optional in addition to Task 1 and should be implemented if development of the land in the vicinity of GM-15 is considered for the near future. Task 1 To define the extent of methane migration in the vicinity of GM-12 , GM-13 , and GM-15, four monitoring wells are proposed. (a) GM-16 would be placed along Starlight Drive, approximately 1000 feet east of GM-13 (Figure A-3) and would further define the extent of migration toward the subdivision southeast of the landfill on Starlight Drive. (b) GM-17 would be placed approximately 500 feet south of I' GM-13 near the edge of the canyon (Figure A-2) . GM-16 and GM-17 would be constructed using a three-probe configuration as shown on Figure A-4 . (c) GM-18 would be placed in the bottom of the canyon west of GM-12 (Figure A-2) and would be constructed with a one-probe configuration as shown on Figure A-5. (d) GM-19 would be placed halfway between GM-15 and the fire station on the corner of Placer Street and Buena Ventura Boulevard (Figure A-1) , and would be constructed with a two-probe II configuration as shown on Figure A-6. Task 2 (optional) Task 2 is optional and would provide for more extensive delineation of the extent of methane migration in the area or land bounded on the northern side by Placer Street, on the Western side by Buena Ventura Boulevard and on the eastern side by the discontinued portion of San Francisco Street (Figure A-1) . (a) GM-20 would be placed halfway between GM-15 and Monitoring Well OB-2, and would provide better coverage in this area. The construction of GM-20 would be similar to GM-15 and GM-19 (Figure A-6) . ii IL 'V 111 • Mr. Ron Masingale ATTACHMENT A City of Redding C89 . 11. 02 Department of Public Works July 6, 1990 760 Park Avenue Page 3 of 11 Redding, CA 96001 Proposal for Services (continued) (b) GM-21 through 24 would consist of shallow, single probe wells (Figure A-5) only, and would be used for screening of near-surface methane concentrations (of greatest concern near structures) . 'I After completion, each monitoring probe will be purged of three volumes using a sampling pump specifically designed for this purpose. The samples will be pumped into 10-liter Tedlar bags and sent to Curtis & Tompkins in Berkeley for analyses of gross- gas constituents. Gross-gas constituents include oxygen, nitrogen, carbon dioxide, carbon monoxide, and methane. Results of the well installation, analyses, and data interpretation will be presented in a report to the City of Redding following completion. i ! � � • Mr. Ron Masingale ATTACHMENT A City of Redding C89. 11. 02 Department of Public Works July 6, 1990 760 Park Avenue Page 4 of 11 Redding, CA 96001 Ilip Cost Estimate Task 1 Materials Units Item Unit Needed $/Unit Total $ 8-inch locking lid ea 4 32.63 130. 52 8-inch x 3-foot steel riser ea 4 20.00 80. 00 1/4-inch stainless-steel plug ea 10 5.00 50. 00 1-inch blank casing, sch 80 ft 300 2. 00 600. 00 1-inch PVC slip caps ea 10 1.50 15. 00 ' 1-inch PVC threaded end cap Ea 10 2.00 20. 00 1-inch Viton "0" rings Ea 30 1.00 30. 00 5-gal bucket bentonite pellets ea 2 52.50 105. 00 #90 lb bag concrete ea 72 4.00 288 . 00 100 lb bag Lonestar #3 sand ea 22 6.00 132 . 00 Subtotal 1450. 52 6% Sales Tax 87 . 03 Total Materials 1537 . 55 Services Units Item Unit Needed $/Unit Total $ 1 rl CME 55 auger drill w/ crew hr 40 135.00 5400. 00 Ij Geologist, log holes hr 40 55.00 2200. 00 Geologist, sample wells hr 8 55.00 440. 00 Geologist Reports hr 16 55.00 880. 00 Laboratory Analyses * ea 10 160.00 1600. 00 Caterpillar rental hr 8 80.00 640. 00 i, Total Services 11160. 00 !
