to 7 UM ® BRW, Inc. Jay Hartman January 17, 2001 Page 4 For cost estimating purposes,.we assume that one fill sample from each boring will be analyzed for the above- indicated parameters. Temporary monitoring wells will be installed in each boring. One ground water sample will be collected from each temporary monitoring well. The samples will be analyzed for the following parameters: • VOCs-MDH Method 466A; • DRO-Modified WDNR DRO Method; and • GRO -Modified WDNR GRO Method. For cost estimating purposes, we assume that one ground water.sample from each temporary monitoring well will be analyzed for the above-indicated parameters. The temporary wells will be removed following ground water sample collection. Methane Monitoring Up to five temporary gas-monitoring probes will be advanced at the property to determine the extent which methane is being generated, if any. The exact locations of the probes will be based on the results of the geophysical, .test trench and soil boring investigations. Gas samples, will be collected from each probe for, methane screening with a combustible gas meter. Gas samples will also be collected from the storm sewer manholes across the property for methane screening with a combustible gas meter. Task 5: Phase II Investigation Report Results of the investigation will be compiled into a Phase II Investigation Report. The report will be prepared in accordance with VIC Program guidance,and will include the following: • Background information, including Phase I ESA and geotechnical investigation results; • Drawings depicting site location, site diagram, investigation activities,extent of dump materials, and extent of groundwater impacts; • Graphical portrayal of the geophysical investigation results; • Soil boring,temporary monitoring well and test trench logs; • Tabulated field screening and analytical testing results; • Detailed analysis and summary of the investigation results; and • Conclusions and recommendations regarding the extent and magnitude of impacts at the site, and the need for corrective actions in conjunction with park redevelopment. Task 6 -Response Action Plan BRW will prepare a Response Action Plan (RAP) to address environmental issues related to park redevelopment. The RAP will include details regarding the following: • • worker health and safety; • emission controls during excavation; • characterization and disposition of excavated materials;
