Dear Mr. Dressel: Hull & Associates, Inc. (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). The Scope of Work entails sampling soil gas in the vicinity of off -Site structures and preparing a summary report; continued groundwater monitoring efforts on a quarterly basis for one year; and additional activities as may be necessary and /or as may be requested by IDEM to evaluate potentially complete exposure pathways at and in the vicinity of the Site. Task 1 Soil Vapor Probe Installation Recent temporary groundwater sampling completed upgradient of the Site identified that groundwater exhibiting concentrations of chlorinated VOCs at concentrations exceeding groundwater to indoor air screening levels is present in the vicinity of occupied structures south of Indiana Avenue. To evaluate the extent to which a complete exposure pathway exists in this vicinity, Hull recommends sampling soil gas above groundwater from City -owned property in the immediate vicinity of the occupied structures south of Indiana Avenue. A total of eight soil gas samples, two from each of four locations, will be collected from points located generally at the western and eastern perimeter of vacant City -owned property located between 702 W. Indiana Avenue and 718 W. Indiana Avenue. The samples will be collected at approximate depths of six feet below ground surface (bgs) and 14 feet bgs, which is approximately four to six feet above the uppermost saturated unit at the Site. Soil gas sampling will not be conducted within 48 hours of a significant precipitation event ( >0.1 inches). The soil gas sampling point installation will be performed using a direct push drilling unit (i.e., GeoprobeTM unit). Soil borings will be logged continuously to a depth of approximately 14 feet at each location and screened with a photoionization detector (PID) during installation. Soil cuttings, acetate liners, gloves, etc. will be containerized in a drum onsite. After logging, a small diameter stainless steel screen of approximately 12 inches in length, connected to a piece of flexible tubing of sufficient length to extend above ground surface and allow for sample collection, will be emplaced in the borehole. The borehole surrounding the screen will be filled with appropriately sized sand pack to a depth of six to 12 inches above the top of the screen. A hydrated bentonite seal will be placed above the sand pack. A second shallow sampling point will be similarly installed to a depth of approximately six feet at each sampling location. The tubing will be color -coded to denote deep vs. shallow sampling locations. 6397 Emerald Parkway, Suite 200 • Dublin, Ohio 43016 614.793.8777 fax 614.793.9070 www.hullinc.corn Mr. Chris Dressel June 21, 2016 SB1075.300.0001 Page 2 Approximately 24 to 48 hours following installation of the soil vapor probes, each sampling port will be purged in accordance with IDEM's Remediation Closure Guide, and a sample will be collected via vacuum through a time - weighted flow regulator into a 6 -L stainless steel Summa canister. One duplicate will also be collected. The sealed soil gas samples will be analyzed for volatile organic compounds (VOCs) by EPA Method TO -15. A brief summary report will be prepared with the intent that the results will be shared with IDEM following internal discussions between the City, Hull, and outside counsel. Task 2 Quarterly Groundwater Sampling Events On a quarterly basis beginning in June 2016, groundwater samples will be collected from monitoring wells AMW -1 S (shallow screened depth), AMW -1 I (intermediate screened depth), AMW -1 D (deep screened depth), AMW- 2S /I /D, AMW- 35/I /D, AMW- 5S /I /D, AMW -65/I, AMW -75/I, AMW -95/1, AMW -1 OS /I, AMW- 12S /I, AMW- 14S /I, and AMW -15S /I and submitted to the laboratory for VOC analysis using U.S. EPA Method 8260. 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 QA /QC of field procedures. Purge and decontamination waters will be collected and stored in U.S. DOT - approved 55- gallon drums. Costs to remove, transport, and dispose of eight 55- gallon drums of containerized groundwater and drill cuttings from Task 1 above (which are presumed to be non - hazardous) are included in this task. For the proposed sampling events, in lieu of traditional low -flow sampling methods that were formerly employed at the Site, Hull will continue to deploy passive diffusion bag (PDB) samplers in all monitoring wells, which are a significantly more cost - effective sampling methodology that has been accepted by IDEM. PDBs are polyethylene bags filled with analyte -free water that are hung in monitoring wells for approximately 14 days. Field personnel return to the monitoring well, retrieve the sampler, and collect the sample by filling sampling vials in the same manner as traditional methods. Significant savings are realized by reducing mobilization, purging, and sampling time; by minimizing the volume (and thereby cost and environmental footprint) of field materials such as low -flow tubing; and by eliminating most equipment rental costs. Laboratory analytical subcontractor costs for this Task include the cost of PDBs for each well, and for Level IV QA /QC reporting by the laboratory. A brief draft letter report documenting the results of each quarterly sampling event will be prepared and submitted to the Client for review. Once the draft letter report is reviewed by the Client and finalized by Hull, a copy will be submitted to the IDEM VRP. Task 3 Additional Activities This task will be reserved for additional activities as may be deemed necessary or as may be requested by the City, IDEM, or outside counsel. As these activities are identified, Hull will quantify the estimated level of effort prior to initiating that effort to develop a preliminary budget. Task 4 Project Management, Meetings, and Correspondence This task will be reserved for project management activities such as updating health & safety plans, email and telephone correspondence with all stakeholders, and attending one meeting in Indianapolis with IDEM. SCHEDULE Hull will begin groundwater sampling activities in June 2016, and will schedule the soil vapor probe installation and sampling as soon as practicable, which we estimate to be in early- to mid -July 2016. 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.
