3.0 PROPOSED CLEANUP OBJECTIVES 3.1 Remediation Goals The goal of the cleanup plan for the Site is to abate the risks posed by contaminated soil. As the City intends to redevelop the Site in conjunction with the larger Studebaker Automotive redevelopment as part of a nanotechnology business park, protection of human health and the environment are critical. As a result, the contaminant exposures have been assessed in consideration of these current and potential future uses. 3.2 Potential Cleanup Alternatives The following cleanup alternatives were evaluated, specific to this Site, based on the data available: no further action; capping; excavation, removal, and off -site landfilling; soil washing; and soil solidification. An Analysis of Brownfield Cleanup Alternatives (ABCA) for the Site was prepared in May 2010 and concluded that excavation, removal, and off -site landfilling was the most viable and cost - effective option. Following approval of the ABCA by U.S. EPA and the Indiana Brownfields Program, as part of the administrative record for the project, the ABCA was posted publicly by the City to allow for public review and comment. Based on no public comment, the City issued a Decision Memorandum on June 17, 2010 approving the selected remedial approach. 3.3 Implementation of Remediation Alternative Bid specifications will be prepared, and the City's process for solicitation of publicly- funded projects will be followed to select a contractor for the excavation. Given the fact that cleanup alternatives can also create impacts to the environment (e.g., through the combustion of fossil fuels during excavation and transportation of impacted soils, etc.), the bid specifications for the selected alternative will be written to emphasize that impacts to the environment shall be minimized where possible. Consistent with U.S. EPA Region 5's Greener Cleanups Initiative, the following measures will be urged during implementation of the selected alternative: • Restrict idling of construction equipment and encourage the use of enhanced emission controls; • Use low- sulfur fuel when possible; • Schedule removal work in a manner that eliminates double - handling of materials; and HULL & ASSOCIATES, INC.
