H U 11. May 4, 2012 Ms. Ann Kolata Senior Redevelopment Specialist City of South Bend Department of Community and Economic Development 227 West Jefferson Blvd., 12th Floor South Bend, Indiana 46601 RE: Proposal to Conduct Monitoring Well Installation, Soil Gas Sampling, and Groundwater Sampling; and to Prepare a Remediation Work Plan at Ignition Park (the Former Studebaker Complex), South Bend, Indiana (the Site); SB1068.400.0001. Dear Ms. Kolata: Hull & Associates, Inca (Hull) is pleased to present the City of South Bend Redevelopment Commission (Client) the following proposal to provide professional engineering services for the above referenced project. The purpose of this document is to establish the Scope of Work as we understand it and to provide a fee schedule for the project. The Site, known as Ignition Park, and formerly known as the Studebaker Complex, is enrolled in the Indiana Department of Environmental Management (IDEM) Voluntary Remediation Program (VRP). As impacts to groundwater were previously identified, but since no previously - installed monitoring wells remain following demolition activities, installation of a permanent monitoring well network to evaluate groundwater is necessary prior to completion of a Remediation Work Plan, which is a necessary milestone of the VRP toward closure of the Site. Task 1 Monitoring Well Installation Hull will install monitoring wells at up to ten (10) nested well locations at or in the vicinity of the previous temporary sampling locations (installed in April 2012) shown on Figure 1, as discussed below. In general, our proposed approach entails installing permanent monitoring wells to evaluate the vertical and horizontal extent of chlorinated volatile organic compounds (VOCs) across the Site. The nested wells will be installed at a deep interval (roughly 40 to 50 feet below ground surface (bgs)); an intermediate interval (roughly 30 to 40 feet bgs); and a shallow interval (roughly 20 to 30 feet bgs) at each location. Certain locations may only require the installation of wells to the shallow and intermediate intervals, and other locations may require that the deeper interval be installed to depths roughly ranging between 50 and 60 feet bgs (especially in the south - southwest portion of the site to evaluate a potential off -site source). The locations will be determined during a forthcoming meeting with you and /or Mr. Jitin Kain at the Site to evaluate the status of current construction activities, and may be adjusted slightly in the field based on field observations such as utility locations, etc. 8470 Allison Pointe Boulevard, Suite 120 • Indianapolis, Indiana 46250 800.241.7173 fax 614.793.9070 www.hullinc.com
