H I I' associates, Inc. October 17, 2011 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 Off -Site Monitoring Well Installation and /or Groundwater Sampling in the Vicinity of the Oliver Industrial Park, South Bend, Indiana (the Site); S131066.400.0001. Dear Ms. Kolata: Hull & Associates, Inc. (Hull) is pleased to present the City of South Bend (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 the Oliver Industrial Park, and formerly known as the Oliver Plow Works facility, is enrolled in the Indiana Department of Environmental Management (IDEM) Voluntary Remediation Program (VRP). Additional off -site delineation of chemicals of concern (COCs) in 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 and Groundwater Sampling Event Hull will install monitoring wells and /or temporary groundwater sampling points at or in the vicinity of the sampling locations shown on Figure 1, as discussed below. Please note the location of historical sampling point CTW -3S /D on Figure 1, which is the basis for the sampling locations (both temporary and permanent) proposed herein. Sampling point CTW -3S /D is the location of the downgradient -most sampling point installed during a January 2003 sampling event; at this sampling location, IDEM VRP Tier II Residential and Nonresidential Cleanup Goals were exceeded, but have not been defined further downgradient. In general, our proposed approach entails defining the vertical extent of chlorinated volatile organic compounds (VOCs) downgradient of CTW -3S /D by installing temporary sampling points north and east of CTW -3S /D; submitting those samples to a laboratory and requesting 3 -day turnaround; installing permanent monitoring wells south and west of CTW -3S /D while laboratory analyses on the samples from the temporary points are completed; and installing permanent monitoring wells downgradient of CTW -3S /D at appropriate locations once the vertical extent is defined. As further explained below, this scope of work includes a contingency for an additional sampling event to install temporary sampling points to define the vertical extent of COCs in groundwater downgradient of sampling point CTW -3S /D, should it be necessary. 6435 Castleway West Drive, Suite 119 • Indianapolis, Indiana 46250 800.241.7173 fax 614.793.9070 www.hullinc.com
