This area, now known as Ignition Park, is enrolled in the Indiana Department of Environmental Management's Voluntary Remediation Program (VRP). Now that all previous structures have been removed, we need to submit a Remediation Work Plan to VRP by the end of June. This Work Plan will describe the environmental conditions at the site and our proposed remediation plan. Some environmental remediation and soil sampling has taken place as buildings have been demolished. However the groundwater has not been sampled in a number of years. This proposal covers the sampling of the groundwater using temporary sampling techniques. Once sampling results are received, Hull may propose the installation of permanent groundwater monitoring wells. This would be covered by a separate proposal from Hull. The staff recommendation is to approve the proposal from Hull & Associates in the amount of $56,702.00. This will allow us to move forward with the groundwater sampling in order to submit our Remediation Work Plan to IDEM by the June 30 deadline.

April 4, 2012 Ms. Ann Kolata Senior Redevelopment Specialist City of South Bend Department of Community and Economic Development 227 West Jefferson Blvd., 12`h Floor South Bend, Indiana 46601 RE: Proposal to Conduct On -Site Temporary Groundwater at Ignition Park (the Former Studebaker Manufacturing Complex), South Bend, Indiana (the Site); SB1067.400.0001. 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 Ignition Park, and formerly known as the Studebaker manufacturing complex, is enrolled in the Indiana Department of Environmental Management (IDEM) Voluntary Remediation Program (VRP) as VRP Site #6020803. As groundwater has not been sampled from portions of the Site since 2006 (and from the majority of the Site since 2003, updated on- Site delineation of chemicals of concern (COCs) in groundwater is necessary prior to installation of a permanent monitoring well network, and prior to preparation of a Remediation Work Plan (RWP), which is a necessary milestone of the VRP toward closure of the Site. Hull understands that a comprehensive RWP addressing impacts to soil and groundwater beneath, and downgradient of, the Site is due June 30, 2012. The Scope of Work as proposed herein will be implemented quickly to allow for subsequent tasks to be completed timely towards completion of the RWP by June 30, 2012. Task 1 Groundwater Sampling Event Hull will install temporary groundwater sampling points at or in the vicinity of the sampling locations shown on Figure 1, as discussed below. The proposed sampling points correspond to areas where prior or known existing impacts to soil and /or groundwater have been identified during the various stages of assessment, remediation, and demolition activities that have been completed at the Site. Note that the sampling locations may be adjusted based on conditions encountered in the field such as access to rights -of -way, other ongoing construction activities, utilities, etc. Prior to the installation of temporary sampling points, Hull will retain the services of Wightman- 6435 Castleway West Drive, Suite 119 • Indianapolis, Indiana 46250 800.241.7173 fax 614.793.9070 www.hullinc.com Ms. Ann Kolata April 4, 2011 SB1067.400.0001 Page 2 Petrie to survey and stake the locations of the prior or known existing impact locations. The staked locations will serve as the primary basis for locating the installed sampling points; final locations will be subject to relocation in the field as discussed above. Following staking of these points, the Indiana Utility Plant Protection Service (IUPPS) one -call number will be contacted to mark the location of known utilities in the vicinity of the proposed sampling locations. In general, our proposed approach entails defining the horizontal and vertical extent of various chemicals of concern (COCs) in the vicinity of prior or known existing areas of environmental impacts to soil and /or groundwater at the Site. COCs to be investigated include volatile organic compounds (VOCs), semi - volatile organic compounds (SVOCs), U.S. EPA Resource Conservation and Recovery Act (RCRA) metals (both total and dissolved), and polychlorinated biphenyls (PCBs). Not all COCs will be analyzed for at each sampling location, and the sampling scheme is based on the history of use or current or prior presence of these COCs at each location. This task will begin with the advancement of temporary screens using direct -push technologies (e.g., a ST -15 Hydropunch) to a shallow depth (i.e., 26 to 30 feet below ground surface (bgs)), an intermediate depth of approximately 35 to 39 feet bgs, and a deeper depth of approximately 45 to 49 feet bgs at each of thirteen (13) locations. At approximately eight (8) additional locations, temporary screens will be advanced to the shallow and intermediate depths only. As stated above, the locations may be adjusted slightly in the field based on field observations such as utility locations, etc. If necessary, Hull will work with the drilling subcontractor and the appropriate City and St. Joseph County authorities to arrange for access for the work and to clear utilities and to prepare appropriate permits for drilling in the right -of -way. Drill cuttings and sample purge and decontamination water will be containerized and placed on -Site at a location designated by the City. At each location where groundwater sampling is to be conducted, the borehole will initially be advanced to the deeper depth (i.e., between approximately 45 and 49 feet bgs), at which point the outer casing of the sampling system will be withdrawn to expose a four foot long stainless steel wire wrapped screen. Once the screen is exposed, Hull will measure the static water level and lower a decontaminated Waterra foot -valve sampling pump or peristaltic pump to purge the equivalent of five well volumes of water to develop the aquifer surrounding the screen. Following extraction of each well volume, Hull will measure pH, temperature and conductivity to demonstrate that representative groundwater is being sampled. In addition, Hull's representative will note if there is a visible sheen on the extracted water. After development, the temporary well will be allowed rest for approximately 20 minutes prior to sample collection. Following purging, Hull will collect groundwater samples that will be pumped through the Waterra or bladder pump tubing at a flow rate of less than 100 ml /min. Samples will be transferred directly into laboratory- preserved sample containers and placed on ice in a cooler. Following collection of each sample, Hull will retrieve and decontaminate the Waterra foot -valve pump by washing it with Alconox and water and rinsing it with deionized water. In addition, the sample tubing will be replaced between each sampling interval. The groundwater samples in the shallow and intermediate portions of the aquifer will be collected by withdrawing the screen to the appropriate depth and purging and collecting a groundwater sample as described above. The process for purging and collecting the shallow Ms. Ann Kolata April 4, 2011 SB1067.400.0001 Page 3 and intermediate groundwater samples will then be completed as described above. Between each of the sampling locations, the drilling rods and well screen will be decontaminated by washing with Alconox and water solution and rinsing with deionized water. The following sample quantities (including trip blanks, matrix spike /matrix spike duplicates, duplicates, and field blanks) and laboratory analyses are proposed: 1. Up to 105 samples for VOCs in accordance with U.S. EPA Method 8260; 2. Up to 27 samples for SVOCs in accordance with U.S. EPA Method 8270/8270 SIM; 3. Up to 23 samples for total RCRA metals in accordance with U.S. EPA Method 6010/7470; 4. Up to 23 samples for dissolved RCRA metals in accordance with U.S. EPA Method 6010/7470; and 5. Up to 21 samples for PCBs in accordance with U.S. EPA Method 8082. Duplicate samples will be collected at randomly selected monitoring well locations. Field /equipment blanks will also be collected and submitted along with a trip blank for analysis as part of quality assurance /quality control (QA/QC) of field procedures. Purge and decontamination waters will be collected and stored in U.S. DOT - approved 55- gallon drums. As described above, drill cuttings, excess samples, purge water and decontamination water will be drummed and staged at a location on -Site acceptable to the Client. Costs to remove, transport, and dispose of approximately 12 55- gallon drums of containerized groundwater and drill cuttings (which are presumed to be non - hazardous) are included in this task. Following receipt of laboratory results, Hull will immediately evaluate the distribution of COCs in groundwater and present the City with a proposal to install a permanent monitoring well network on- and off -Site. A final report documenting this stage of work will be prepared with the separate letter report documenting installation of the monitoring well network in May 2012. SCHEDULE Hull has tentatively scheduled the initial work (e.g., surveying, utility locates, etc.) for the temporary groundwater sampling event to begin on or about April 11, 2012 subject to your approval of this proposal. Temporary sampling point installation is scheduled to begin April 16, 2012. We anticipate all drilling and sampling activities, and laboratory analyses, will be completed by April 27, 2012, and will immediately prepare a proposal for monitoring well installation by Wednesday, May 2 for consideration at the May 8 Redevelopment Commission meeting. This schedule will allow for completion of the RWP by June 30, 2012 in accordance with the schedule you have proposed to IDEM. COMPENSATION A breakdown of costs is attached as Table 1. The fees have been developed based on our estimate of hours for each labor category expected to be involved in the project. The project will be billed on a four -week basis with payment due to Hull within thirty days after receipt of an invoice.
