samples will be analyzed for the area - specific COCs in accordance with U.S. EPA Method 6010 (for lead); VOCs in accordance with U.S. EPA Method 82601IN Method 5035; TPH in accordance with U.S. EPA Method 8015M; and /or SVOCs in accordance with U.S. EPA Method 8270 as appropriate. Rush turnaround times will be requested on laboratory analyses to allow for expeditious decisions as to whether additional excavation is necessary, or whether the excavations may be backfilled. Should laboratory results of the initial confirmatory soil samples suggest that additional excavation is necessary, Hull will coordinate with the excavation contractor to excavate and dispose of additional soils as appropriate. Additional confirmatory samples will be collected in the vicinity of any additional excavation to confirm that soils remaining at the Site meet Cleanup Goals . The horizontal and vertical extents of all excavations will be measured and surveyed using GPS coordinates prior to backfilling. Following receipt of laboratory analyses indicating that Cleanup Goals for COCs have been met, the excavation will be backfilled to grade with clean fill material similar to the surrounding soils. Compaction standards will not be specified. The excavated areas will then be capped with a layer of topsoil and seeded. 3.4 Data Management Because the excavation will likely be completed within several weeks, quarterly reports are not anticipated. Following completion of the excavation, a soil remediation completion report will be prepared and submitted to the City, U.S. EPA, and the Indiana Brownfields Program. The report will generally follow the requirements of IDEM's RISC User's Guide and will include a background of the Site, a description of the remedial actions completed at the Site, confirmatory sampling results (including a comparison to Cleanup Goals), a description of the activities completed to restore the Site to grade, and conclusions /recommendations as appropriate. 3.5 Proiect Schedule The anticipated project schedule is as follows: 1) Approval of Soil Remediation Work Plan by Indiana Brownfields Program — month 0; HULL & ASSOCIATES, INC.
