HomeMy WebLinkAbout6B(1)�g o 45a�T� e f Department of d! Community Investment 1865 Memorandum Monday, January 27, 2014 TO: Redevelopment Commission FROM: Ann Kolata & Chris Dressel SUBJECT: Proposal from Hull regarding Environmental Delineation and Sampling in the area of Ignition Park Attached is a proposal from Hull for additional environmental work in the area of Ignition Park. Ignition Park has been enrolled in the Indiana Department of Environmental Management's (IDEM) Voluntary Remediation Program (VRP) for a number of years. While much of the soil and groundwater has been previously sampled, additional work is needed in order to prepare a revised Remediation Work Plan for the VRP project. This proposal addresses a number of tasks that must be completed including: Preparation of a Sampling and Analysis Plan for on- and off -site soil and groundwater sampling. Preparation of an updated Health and Safety Plan and Quality Assurance Project Plan as requested by IDEM. Coordination with IDEM regarding next steps for moving through the VRP process. Some additional soil sampling. Coordinate evaluation of any potential vapor intrusion issues. Installation of temporary and permanent groundwater sampling points and sampling of the groundwater. Conduct quarterly groundwater monitoring for eight quarters. Evaluate groundwater remedies (depending on results of groundwater sampling) Restrict use of groundwater through establishment of an Administrative Control Area under St. Joseph County Code limiting the installation of private drinking wells. Since the area is already served by the City of South Bend water department this will not cause problems within the area. The proposal from Hull provides additional detail on each of these items. The work will be billed as tasks are performed and has a "not to exceed" cap of $300,778. The final cost could be less depending on the results of the soil groundwater sampling. The extent of this work has been anticipated for several years and the funds are available as part of the Studebaker /Oliver project. 227 W. JEFFERSON BLVD.

Dear Mr. Dressel: 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. This SrRSRZC6rH4-hV0!HuQ& A\XRFIDVW ,nF.'V(Hu(W rHcommendations for additional tasks needed to conduct additional assessment activities and prepare an amended Indiana Voluntary Remediation Program (VRP) Remediation Work Plan (RWP) for land at Ignition Park (the Site, also known as Area A and /or the former Studebaker manufacturing complex) and additional off -site properties. Site Physical Setting and Background The Site is comprised of several parcels totaling approximately 79.5 acres (H / -) of land located southeast of the intersection of Sample Street and Prairie Avenue in South Bend, Indiana. Operations under Studebaker Corporation, from as early as 1927 to the early 1960s, consisted of a foundry, lumberyard, and manufacturing facilities, primarily dedicated to the manufacture of automobiles. ) R(MwwlnJ Wl`f FHVeD\)Vn RI 6N6&E DN+'VRSHrD\LVnVDVYhe Site, the majority of the Site was subdivided and sold to various business entities. Although the City is in the process of establishing new parcels at the Site, all former parcels but one comprising the Site are currently vacant. Various stages of infrastructure improvements (e.g., road construction and utility installation) have occurred or are occurring in an area generally limited to the southern third of the Site, and Hull understands that one or more parcels along Sample Street may be redeveloped in 2014. Multiple environmental assessments have been conducted at the Site. These assessments included sampling and testing of surface and subsurface soils and groundwater for chemicals of concern (COCs) including volatile organic compounds (VOCs), total petroleum hydrocarbons (TPH), semivolatile organic compounds (SVOCs; also herein referred to as polynuclear aromatics (PNAs)), Resource Conservation and Recovery Act (RCRA) metals, Target Analyte List (TAL) metals and /or polychlorinated biphenyls (PCBs). During the process of conducting the additional environmental assessments, IDEM requested in 2003 -2004 that the City submit a RWP to address impacts in soil identified at the Site. Despite suggestions from the City and Hull that a RWP for soils was premature in the absence of a complete understanding of the distribution of impacts to soils at the Site, Hull submitted a RWP for soils in April 2004. Following the submittal of the April 2004 RWP, IDEM requested additional assessment for soils and groundwater. Additional on- and off -Site assessment activities continued through 2011 -2012. 8470 Allison Pointe Boulevard, Suite 124, Indianapolis, Indiana 46250 800.241.7173 614.793.9070 fax www.hullinc.corn Mr. Chris Dressel SB1072.400.0002 January 27, 2014 Page 2 In September 2012, following further discussions with IDEM, Hull submitted a Comprehensive Environmental Summary Report for the Site that summarized all environmental assessment work completed at the Site to date. The summary report acknowledged that additional off -Site assessment of groundwater would be necessary and presented a general path forward for that additional assessment. While the direction of the future remedial approach for groundwater is yet to be determined, it currently appears that the main driver for the remedial approach will center upon ensuring that the groundwater to indoor air exposure pathway for both existing and future structures is incomplete for both on- and off -Site receptors. Minor historical detections of COCs in soils in isolated areas across the Site may require additional assessment and /or handling during future unspecified redevelopment activities, but are not expected to materially impact the overall remedial strategy for the Site. In April 2013, IDEM responded with comments to the Comprehensive Environmental Summary Report. The City and Hull have engaged in verbal and electronic mail correspondence with IDEM on the path forward, but have not yet fully and formally responded to IDEM'VP RVWHFHn\NYrNft FRrrespondence. In general terms, IDEM, the City, and Hull agree that additional on- and off -Site assessment activities to evaluate the vertical and horizontal distribution of VOCs in groundwater are necessary prior to the submittal of a RWP. However, the extent to which those assessment activities are necessary has not been resolved, as discussed below. This current proposal presents, on a time and materials, not -to- exceed basis, a scope of work and costs to implement steps that will likely be necessary to complete additional assessment activities, prepare an amended RWP, and, once approved by IDEM, implement the RWP to ultimately receive from IDEM a Covenant Not to Sue pursuant to the VRP. This current proposal also incorporates tasks required to evaluate any potential vapor intrusion issues on- and off -Site. The following additional activities are proposed: Task 1 Prepare Various IDEM VRP Documents A Sampling and Analysis Plan (SAP) detailing the locations, sampling methods, and laboratory analyses proposed for the next stages of on- and off -Site soil and groundwater sampling must be prepared and approved by IDEM. The SAP will explain field activities that will be completed in Tasks 3 and 4 as described below. IDEM has also requested that an updated Health and Safety Plan (HASP) and n uality Assurance Project Plan (n APP) be submitted for their review and approval. Hull proposes to submit revised versions of the existing SAP and existing n APP firMRr ,D(0 'V FRnV- G+D\Jyn, Y" I ROw wLW/Dn updated HASP prior to the initiation of field activities. This task includes communication with the IDEM regarding next steps for additional assessment activities at the Site, strategic discussions to efficiently further guide the Site through the IDEM VRP, and meetings with the City to discuss approaches for evaluating any potential vapor intrusion issues at on- and off -Site properties as necessary. Task 2 Coordinate Evaluation of Any Potential Vapor Intrusion Issues Hull proposes to coordinate efforts with the City, the IDEM, and other interested parties to evaluate any potential completeness of the groundwater to indoor air exposure pathway that may exist on- or off -Site. Hull assumes that our coordination efforts will entail attendance at meetings, written and telephone correspondence, and communication with IDEM as deemed appropriate. Hull proposes a comprehensive scope of work to evaluate whether any potentially complete exposure pathway may exist at current or future on- or off -Site structures. Mr. Chris Dressel SB1072.400.0002 January 27, 2014 Page 3 Should any potentially complete vapor intrusion exposure pathways be identified, depending upon the nature and extent of the potential vapor intrusion i%H, Hu®V\f+vLFHVP Dy InFOO-i V1H I R(MwwlnJ W".. a. Task 1: Enaineerina review of facility systems at current or future structures: This task would primarily consist of an in -depth review of available structural documentation, including architectural and mechanical design /construction documentation. b. Task 2a• Interview current operations & mainWMDnFH V491 I DnG RwnHr'V rHSrHV+\DNb1 -V This task would include interviews of any designers, staff, and /or appropriate maintenance service providers to clarify current or proposed heating, ventilation, and air conditioning (HVAC) system operations.. C. Task 2b• Validate current or proposed HVAC control conditions: This task may include an evaluation of the proposed HVAC system, or functional tests of an existing HVAC system to evaluate technical details such as air supply and exhaust quantities. d. Task 2c• Measure and validate existing HVAC airflow quantities: If appropriate for an existing HVAC system, for this task, Hull may measure, through industry standard procedures, the facility outside air and exhaust airflow quantities. e. Task 2d• Measure and validate existing_ building pressures: If appropriate for an existing structure, this task would entail detailed evaluations such as measurement of current building pressure relative to the outdoors at both minimum and maximum outside air operational conditions. f. Task 2e• Determination of Beneficial Outside Air n uantity: If data collected during Task 2d at an existing structure suggest that an HVAC system may be enhanced to maintain an industry accepted positive building pressure, Hu ®P Dy FRP S(EWt' 7D\N 2H DVVM &LWV discretion. Hull will conduct Tasks 1 and 2a. through 2d. above in a step -wise manner to control costs and realize efficiencies where feasible. Hull will initially complete Tasks 1 and 2a above, should any potential current or future vapor intrusion issues be identified. Next, as deemed appropriate, Hull will conduct Task 2b above, should the results gained from the completion of Tasks 1 and 2a suggest that Task 2b will provide meaningful results. Finally, Hull will complete Tasks 2c, 2d, and 2e above should they be deemed necessary and meaningful, and only subject to specific prior written authorization by the City. Should they be identified as necessary, Hull offers that the costs to complete Tasks 2c, 2d, and 2e concurrently could result in relatively significant savings by realizing efficiencies from a single mobilization, reduced per diem costs, etc. Should it be deemed that Tasks 2c, 2d, and 2e are necessary, Hull commits to evaluating the most reasonable, cost - effective, and meaningful approach with the City prior to seeking authorization for Tasks 2c, 2d, and 2e. Task 3 Install Temporary and Permanent Groundwater Sampling Points This Task will begin with a Site visit to evaluate the presence and condition of all on -site monitoring wells, as well as to mark boring locations before public utility locators are contacted. Additional on -Site groundwater sampling (through the installation of permanent monitoring wells, as presented below) to evaluate the potential impact from COCs associated with the former Studebaker operations is required. Also, as we have discussed, an evaluation of the extent to which off -Site sources may have impacted groundwater underlying the Site is necessary. The installation and sampling of a series of temporary groundwater monitoring points in the vicinity of the area generally bounded by hendall Street (and alley to the west), Edward Street, Scott Street, and Indiana Avenue south and west of the Site (i.e., across the upgradient sectlRn RI J rRunGwDWIF I nW%lnJ V1H 61]WV\Ru\%H`MDrFH (PwIJ(MIJG1n Mr. Chris Dressel S61072.400.0002 January 27, 2014 Page 4 evaluating where off -Site sources may be contributing to the groundwater impacts that have been observed at the Site. In addition, groundwater samples from nested temporary locations at up to eight additional locations downgradient (i.e., north and east of the Site) are proposed to be collected from within City right -of -way in Lafayette Boulevard and in the vicinLWRI \W ",vy 7RwHr" SrRSHrWDnd from within City right -of -way in Main Street between the railroad tracks and Monroe Street to evaluate the downgradient distribution of chlorinated VOCs. In general, our proposed approach entails defining the vertical extent of chlorinated volatile organic compounds (VOCs) upgradient of AMW -1 S (shallow), AMW -11 (intermediate), and AMW -1 D (deep) (located at the immediate southwest corner of the Site) by installing four relatively shallow, intermediate, and relatively deeper temporary sampling points (installed at four nested sampling locations) within the area generally bounded by hendall Street (and alley to the west), Edward Street, Scott Street, and Indiana Avenue south and west of the Site; then installing relatively shallow and relatively deeper temporary sampling points in the vicinity of Lafayette Boulevard (4 nested sampling points) and Main Street (4 nested sampling points) as discussed above. 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, for upgradient locations, at a deeper depth of approximately 45 to 49 feet bgs, subject to approval of these IocationVlrRP V1N &O-bVVBRDrGRI 3uEU : RrIW(B3: ). The locations may be adjusted slightly in the field based on field observations such as utility locations, etc. 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. Adjacent property owners will be notified by certified mail prior to the initiation of any drilling activities. Drill cuttings and sample purge and decontamination water will be containerized and placed 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 deepest depth proposed for that location, 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 samplHd. ,n addition, Hull's rHprHsH ntativH 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. pamples 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 sample in the upper portions of the aquifer (i.e., shallow and intermediate, as appropriate) 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 relatively shallower groundwater sample will then be completed as Mr. Chris aressel pB1072.400.0002 gcinuary 27, 2014 rrage 5 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. r p to 28 groundwater samples plus 20 n A/n C samples, collected from the temporary boreholes using direct -push technologies, will be analyzed for s I Cs. Five field blanks and five trip blanks will also be analyzed for s I Cs. Costs for the laboratory analyses assume i evel Is data packages will be provided by the laboratory, as required by the IaEM s om Following installation of the temporary sampling points, eight deep and shallow nested monitoring wells will be installed on -pite to further evaluate the potential presence of Cl Cs in groundwater along the western perimeter of the pite (along prairie Avenue /Chapin ptreet); and off -pite to further evaluate the downgradient distribution of s I Cs north and east of the pite. Final locations of permanent monitoring wells will be determined during proposed meetings with the City, its outside counsel, and Mr. Ed ptefanek of t eaver -Boos Consultants. poil borings associated with the proposed monitoring wells will be drilled using 4.25 -in., inside - diameter hollow -stem augers and continuously sampled using 24 -in. split -spoon samplers to the appropriate depth (i.e., either 30 feet bgs or 45 feet bgs). pimilar to the locations of the direct -push sampling points, the final locations of the monitoring wells may be modified based on field observations. Although the deeper boring at each location will be continuously sampled, soil samples are not proposed to be submitted for laboratory analyses as part of the monitoring well installation. Monitoring wells will be constructed of pchedule 40 rm C slotted screens and risers. I nce 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. podium 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 a flush -mount manhole. Monitoring wells will be developed following installation to remove fines that may have entered the well screen or filter pack during installation. t ell 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. aevelopment waters will be collected and stored in a al T approved 55- gallon drum. Costs to remove, transport, and dispose of approximately 52 55- gallon drums of containerized groundwater and drill cuttings (which are presumed to be non - hazardous) are included in this task. Following the installation of these newer monitoring wells, the top of casing and ground elevations of the new wells will be surveyed so that the groundwater elevations measured in these wells can be compared relative to the other wells in the monitoring network. Task 4 Conduct Quarterly Groundwater Monitoring Following the installation of new monitoring wells, a routine of quarterly groundwater sample collection from all monitoring wells is proposed. This will establish a baseline and, after several quarters, will begin to allow for seasonal trend analysis. After four to six quarters, a sufficient trend should be established to allow for an analysis of whether certain monitoring wells can be removed from the quarterly sampling routine, with IaEM concurrence. Mr. Chris aressel pB1072.400.0002 gcinuary 27, 2014 rrage 6 In the meantime, however, this estimate assumes that quarterly groundwater samples will be collected from all existing and newly - installed monitoring wells on- and off -pite (an estimated total of 37 monitoring wells) for 8 quarters. d roundwater samples will be collected from all newly installed monitoring wells and submitted to the laboratory for s I C analysis using r .p. En-4 Method 8260. auplicate 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 n A/n C of field procedures. rrurge and decontamination waters will be collected and stored in r .p. al T- approved 55- gallon drums. Costs to remove, transport, and dispose of eight 55- gallon drums of containerized groundwater and drill cuttings (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 have been employed at the pite previously, Hull proposes to deploy passive diffusion bag (ma B) samplers in all monitoring wells, which are a significantly more cost - effective sampling methodology that has been accepted by IaEM. rraBs 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. pignificant 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. iaboratory analytical subcontractor costs for this Task include the cost of moBs for each well, and for i evel Is n A/n C reporting by the laboratory. This estimate assumes that the City and Hull will succeed in gaining IaEM approval to cease sampling groundwater for metals, which should be acceptable given the proposed restriction of groundwater use as discussed in Task 5 below. A brief draft letter report documenting the results of each quarterly sampling event will be prepared and submitted to the Client for review. I nce the draft letter report is reviewed by the Client and finalized by Hull, a copy will be submitted to the IaEM s om Task 5 Evaluate GW Remedies Restrict GW Use, and Amend the RWP I nce the extent of downgradient groundwater impacts, the current status of groundwater impacts on -pite, and the potential off -pite [i.e., south and southwest (upgradient)] sources that may be contributing to groundwatHr HntHring thH 6itH's southHrn Eoundary arH better understood by the activities to be completed in steps 3 and 4 above, the prior remedy (i.e., EOST") that was pilot tested at the nearby I liver Industrial 3ark — and shown to EH HI I I -FtivH — will EH Hvaluated for additional applications. As the groundwater in- situ treatment technology market has evolved in the last 3 -4 years, we will commit to evaluating similar chemistries that may offer a cost and /or effectiveness advantage. aepending upon the results of the groundwater sampling proposed herein, the actual necessity of a groundwater remedy (i.e., beyond engineering and /or institutional controls) will be evaluated first and foremost prior to the recommendation of any groundwater remediation technology. As we have discussed previously, Hull recommends that the City effectively render incomplete the groundwater ingestion exposure pathway at and in the vicinity of the pite by ensuring that pt. g:)seph County Code 52, pection 52.042 is enforced, which prohibits the installation of wells for potable use where a municipal water source is available, and pection 52.043 is implemented for the vicinity of the pite, which governs the establishment of an Administrative Control Area (ACA). The language of pection 52.043, whereby an ACA is established, contains additional relatively far- reaching yet flexible provisions to further restrict exposure to groundwater when a threat to human health may be present. Hull and the City's outsidH FounsH haves alrHady HngagHd thH 6t. gDseph County Health aepartment to begin the process of establishing an ACA, and will continue to pursue this effort. t e are confident that once the Mr. Chris aressel pB1072.400.0002 gunuary 27, 2014 rrage 7 ACA is established, the groundwater ingestion exposure pathway will officially be rendered incomplete, thereby eliminating the need to sample groundwater on- and off -pite for any metals concentrations. The results of the evaluation of the proposed groundwater remedy, the extent to which a future remedy is necessary based on the additional groundwater delineation and monitoring, and the progress of establishing the ACA will be summarized in a of m A draft of the forthcoming amended of m will be provided to the City and its outside counsel prior to finalization and submittal to IaEM. SCHEDULE Hull can begin coordinating the additional groundwater investigation and evaluation of any potential vapor intrusion issues immediately, subject to your approval of this proposal. Assuming our drilling subcontractor remains reasonably available, we anticipate all drilling and initial groundwater sampling activities will be completed by the end of February 2014. COMPENSATION A breakdown of costs is attached as Table 1. The fees represent a time and materials, not -to- exceed fee structure basis, and 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.
