Last month you approved a proposal for groundwater sampling in the former Studebaker Area north of Sample Street. This area, now known as Ignition Park, is enrolled in the Indiana Department of Environmental Management's Voluntary Remediation Program (VRP). The sampling under that proposal has been completed and it is now time to install permanent monitoring wells for sampling both now and over the next few years in conjunction with the remediation that will be proposed in the Remediation Work Plan. This Remediation Work Plan needs to be submitted to the Indiana Department of Environmental Management by June 30`" The staff recommendation is to approve the proposal from Hull & Associates in the amount of $128,469.00. This will allow us to move forward with the installation of the permanent monitoring wells, complete the next round of sampling and prepare the Remediation Work Plan to IDEM by the June 30 deadline. Please contact me at 235 -9374 or akolataksouthbendin.gov if you have any questions. 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 Ms. Ann Kolata May 4, 2012 S61068.400.0001 Page 2 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 at a location designated by the City. Monitoring wells will be constructed of Schedule 40 PVC slotted screens and risers. Once the targeted depth has been reached, the well column will be slowly lowered to the base of the borehole. A clean silica quartz sand filter pack will be placed around the screen and will extend no more than two feet above the top of the screen. Sodium bentonite chips or pellets will then be placed on top of the sand pack. Above the chips or pellets, a thick bentonite slurry will be pumped into the annular space using a tremie pipe to a depth of approximately three feet below ground surface. The remaining three feet will be filled with concrete to anchor an above - ground (i.e., "stick -up ") protective casing (please note that these above - ground protective casings may be removed and replaced with flush -mount manhole covers if desired by the City in the future). Monitoring wells will be developed following installation to remove fines that may have entered the well screen or filter pack during installation. Well development activities will continue until pH, temperature, and conductivity have stabilized for three consecutive well volumes, or until five well volumes have been removed, whichever is greater. Development waters will be collected and stored in a DOT approved 55- gallon drum. Task 2 Soil Vapor Probe Installation The recent temporary groundwater sampling completed in April 2012 identified that groundwater exhibiting concentrations of chlorinated VOCs at concentrations exceeding groundwater to indoor air screening levels is leaving the Site at the northeastern boundary along Sample and Franklin Streets. To evaluate the necessity of installing monitoring wells off -Site, under the assumption that the groundwater to indoor air exposure pathway will likely drive any remedial and /or monitoring approach recommended in the forthcoming RWP, Hull recommends sampling soil gas above groundwater along Sample and Franklin Streets to evaluate whether any existing or future groundwater to indoor air exposure pathway is potentially complete. A total of eight soil gas samples, two from each of four locations, will be collected from points located generally along the rights -of -way of Sample and Franklin Streets in the northeast portion of the Site. 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. Ms. Ann Kolata May 4, 2012 S131068.400.0001 Page 3 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 locations will be sampled concurrently with the newly - installed monitoring wells as proposed below. Task 3 Groundwater and Soil Gas Sampling Event Groundwater samples will be collected from all newly installed monitoring wells and submitted to the laboratory for VOC analysis using U.S. EPA Method 8260. Prior to sampling, the monitoring wells will be purged until pH, temperature, and conductivity measurements have stabilized, or until three well volumes have been removed, whichever is greater. Following purging, groundwater will be collected using low -flow methods and transferred to laboratory- preserved sample containers at rate of less than 100 ml /min and placed on ice in a cooler. 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. As described above, drill cuttings, excess samples, purge water and decontamination water will be drummed and staged at a location acceptable to the Client. Costs to remove, transport, and dispose of approximately 100 55- gallon drums of containerized groundwater and drill cuttings (which are presumed to be non - hazardous) are included in this task. Approximately 24 to 48 hours following installation of the soil vapor probes, each sampling port will be purged in accordance with IDEM's Draft Vapor Intrusion Pilot Program Guidance, 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. For the purposes of this cost estimate, it is assumed that the soil will be disposed of as a non - hazardous waste. Task 4 Remediation Work Plan Preparation The RWP that was submitted to IDEM in April 2004 will be revised to include additional narratives that describe all past environmental sampling programs completed at the Site. In addition, this revised RWP will include a description and analytical results of the impacted soil areas discovered during demolition activities throughout the former Studebaker Complex. Furthermore, references to groundwater (previously removed when groundwater was to be remediated through a separate VRP number in conjunction with other areas within the City) will be reincorporated into the RWP. To the extent possible, the revised RWP will include copies of analytical reports, summary tables, and location plans for historical soils investigations. Note Ms. Ann Kolata May 4, 2012 S131068.400.0001 Page 4 that there may be inaccuracies in historical sampling locations, as presented on the maps, due to a lack of survey data and /or detailed historical site plans. Hull envisions that multiple figures will need to be prepared to clearly show the previous sampling locations and analytical summaries. Hull will revisit and update as necessary the draft health and safety plans, quality assurance project plans and the community relations plans that were submitted in April 2003 into a single set of project documents that will be inclusive of all anticipated activities associated with the general remediation approaches for soil and groundwater. A minimum of two hard copies and four electronic (PDF on compact disc) copies of the final deliverables will be prepared and submitted to the City and the IDEM VRP Project Manager for the Site. SCHEDULE Hull has tentatively scheduled the monitoring well installation to begin the week of May 14, 2012, subject to the Redevelopment Commission's approval of this proposal. Permanent monitoring well installation and development will likely require up to three weeks to complete. Assuming groundwater sampling and soil gas sampling are completed immediately thereafter, we anticipate all drilling and sampling activities will be completed by June 8, 2012. This schedule will allow for completion of the RWP by late June in accordance with the June 30, 2012 deadline you have agreed to with Mr. Jeffrey Kavanaugh of 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.
