Staff has been in discussion with the owners of Hamilton for several years about the purchase of their property at 802 -812 S. Lafayette, 910 -912 S. Lafayette and 901 -917 S. Lafayette. Recently the owners of Hamilton have indicated their interest in selling the property to the Commission. They are interested in an agreement for all three properties with transfer of title taking place on a staged basis over a two year period. The property at 802 -812 S. Sample is adjacent to the Indiana Michigan Power sub - station and this property will be needed for I & M to expand its sub - station as part of Kevin Smith's Renaissance Project. The other two properties are adjacent to Ignition Park and are included in the master planning for Ignition Park. Phase I Environmental Site Assessments were completed in November 2008 for each of the three properties. They suggested additional environmental testing at each of the three locations. This work includes the use of ground penetrating radar to determine if any Underground Storage Tanks are still located on the properties, soil sampling, groundwater sampling and dye tracing of existing trench drains located in the buildings to determine if they are discharging to the sanitary sewer system. In addition, the Phase I Environmental Site Assessment must be updated within six months of acquiring title to the property. The Wightman Petrie proposal includes Phase I updates for two of the properties as the third property is not expected to be acquired for about two years. The staff recommendation is to approve the proposal from Wightman Petrie in the amount of $20,800. This will allow us to move forward with the Phase II testing as soon as possible to determine if there are any environmental conditions at the properties and to update the Phase I assessments once a purchase agreement is finalized. Please contact me at 235 -9374 or akolata a,southbendin.gov if you have any questions. March 27, 2012 South Bend Redevelopment Commission 227 W. Jefferson Blvd., Suite 1200 South Bend, Indiana 46601 RE: PROPOSAL FOR PHASE I UPDATES AND PHASE II ENVIRONMENTAL SITE ASSESSMENTS, HAMILTON BODY SHOP /HAMILTON TOWING FACILITIES, SOUTH LAFAYETTE BLVD., SOUTH BEND, INDIANA, PROPOSAL # WP12 -020 Wightman Petrie is pleased to submit this proposal for performing Phase I Environmental Site Assessment Updates for the two (2) properties (802 -812 S. Lafayette Blvd., 910 -912 S. Lafayette Blvd.) identified as being occupied by Hamilton Towing operations, as well as Phase II Environmental Site Assessment (soil and groundwater sampling) for the aforementioned Hamilton Towing properties, and the Hamilton Body Shop, located at 901 -917 S. Lafayette Blvd., in South Bend, Indiana. All three (3) of the properties were the subject of Phase I Environmental Site Assessments performed by Wightman Environmental, Inc. (WEI) dated November 10 and November 14, 2008, for which recommendations for Phase II Environmental Site Assessments were made. We understand that the City of South Bend is currently negotiating the purchase of the three (3) properties, with the idea of taking immediate possession of the 802 -812 S. Lafayette Blvd. and 910 -912 S. Lafayette Blvd. tracts, and allowing for continued occupation, through some pre- determined date, for the 901 -917 S. Lafayette property. As such, the Phase I Environmental Site Assessment Update for the 901 -917 S. Lafayette Blvd. property, which has a time limitation of 6 months from the date of issuance, will be scheduled for a later date, which coincides with possession of the 901 -917 S. Lafayette Blvd. property by the City of South Bend. The City of South Bend is interested in performing environmental due diligence for each of the properties prior to taking possession as part of the proposed real estate transaction. Historical Phase I Environmental Site Assessments, the latest being completed in November 2008, have been performed for each of the three (3) properties, and are summarized, as follows: W. IGHTI IA ETRIE ARCHITECTURE GIS CIVIL ENGINEERING LANDSCAPE ARCHITECTURE ENVIRONMENTAL PLANNING RENEWABLE ENERGY LAND SURVEYING Hamilton Body Shop /Hamilton Towing March 27, 2012 Page 2 of 10 802 — 812 S. Lafayette Blvd. (Hamilton Tow Yard) — consists of four (4) parcels of land (018- 3042 -1607 through 018 - 3042 -1610) totaling approximately 0.58 acres. The northernmost lot is developed with one (1) structure that was reported to have been used as garage space for storage of Hamilton Towing fleet vehicles. Office space is present on the south side of the structure. The remainder of the property is currently being used for the storage of automobiles, trailers and machinery associated with the Hamilton Towing operations. The entire property is enclosed with an aluminum fence, with access via a locking swing gate along S. Lafayette Blvd. Historically, an auto repair station occupied the subject site from 1949 through at least 1980 (Sanborn Fire Insurance Maps), with two (2) gasoline USTs having been located on the south side of the former auto service building. In addition, the current owner has indicated that a heating oil UST system was excavated from the ground on the east side of the existing building. In addition, a hydraulic lift, no longer in use, was identified as having been left in the ground, within the existing building. The subject property was not identified by the regulatory database search; however there was significant potential for on -site migration of contaminants from surrounding sources. 910 -912 S. Lafayette Blvd. (Hamilton Towing) — consists of three (3) parcels (018- 8001 -0001, 18 -8001- 0002 and 018 - 8001 - 00201) totaling approximately 0.33- acres. The subject site is developed with one (1) structure which is occupied by Hamilton Towing, and being used as office space and a fleet storage and maintenance facility. Mr. Hamilton indicated that the building was originally constructed in the 1920s, and contained a trench drain that extends the entire length of the building, for which Mr. Hamilton was unfamiliar with the point of discharge. Bulk storage of petroleum products and hazardous materials (i.e., diesel fuel, lubricants, solvents, etc.) was identified in the maintenance area of the building, in addition to two (2) oil ASTs, drums and smaller sized (commercially available) containers throughout the building. Historical Sanborn Maps indicate use of the building as an auto repair facility from 1917 through at least 1980. The subject property was not identified by the regulatory database search; however there was significant potential for on -site migration of contaminants from surrounding sources. 901 -917 S. Lafayette Blvd. — consists of five (5) parcels (018- 8002 -0094, and 018 - 8002 -0096 through 018 - 8002 -0099) totaling approximately 0.93 -acres of land. The subject site is developed with three (3) structures. A large building is located near the center of the property which is used as an office and maintenance garage. A second building that appears to be used as a paint shop and storage space, and a third building used for storage, are located near the southwest corner of the property. According to Sanborn Maps, the historical use of the property includes residential, a gasoline service station, and an auto junk yard. Such historical operations were deemed as having the potential for significant use and /or storage of hazardous materials and petroleum substances. Trench drains are present within the facility for which the owner is not aware of the point of discharge. The former gas station, located at the southwest corner of the intersection of W. Sample St. and S. Lafayette Blvd., was the location for removal of four to five UST systems in the 1990s's following purchase by Mr. Hamilton. An additional vent pipe was identified in the northern portion of the subject property. In addition, underground hoists associated with the gas station operations were also removed from the ground. Three (3) ASTs, all of which were labeled as "gas ", were identified at the northern portion of the building, with two (2) of the ASTs within secondary containment. Numerous unlabeled drums and petroleum containers were also present on the north side of the building. Junk cars being staged at the rear of the buildings (aluminum fencing present) were not drained of fluids prior to storage. The subject property was identified by the regulatory database search as a RCRA Generator as well as cross - indexing lists such as FINDS and the Indiana Manifest List. There also exists significant potential for on -site migration of contaminants from surrounding sources. PROPOSED SCOPE OF SERVICES The following tasks detail the proposed Scope of Services by Wightman Petrie, consisting largely of the Phase I Environmental Site Assessment Updates (last Phase I performed in 2008), and the Phase II Environmental Site Assessment, as proposed by the 2008 Phase I Reports. Please note that during the Phase I Updates modifications to the proposed Phase II Scope of Service may be warranted, noting that the current owner may have undertaken some level of clean -up action. Hamilton Body Shop /Hamilton Towing March 27, 2012 Page 3 of 10 TASK 1 — Phase Environmental Site Assessment Updates It is the intent of Wightman Petrie to perform the Phase I Update in general accordance with the American Society for Testing and Materials (ASTM) document ASTM E 1527 -05, which is considered consistent with the provisions of EPA's All Appropriate Inquiry. The proposed Phase I Environmental Site Assessment Update will consist of the following components: • Records Review • Site Reconnaissance • Interviews • Reporting RECORDS REVIEW The purpose of the records review is to obtain and review records that will help identify environmental concerns in connection with the subject site. As part of this phase of the project, we will attempt to obtain and review those records that are "reasonably ascertainable." For the purposes of this proposal, "reasonably ascertainable" information is defined as: (1) publicly available, (2) obtainable from its source within reasonable time and cost constraints, and (3) practically reviewable. The assessment will include a review, where available or applicable, of both Environmental and Historical sources. ENVIRONMENTAL RECORDS REVIEW The following publicly available listings will be reviewed: Standard Environmental Records Search Distance (Miles from Boundaries) Federal NPL Site list 1.0 Proposed NPL Site List 1.0 Delisted NPL Site List 1.0 NPL Liens List Target Property Federal CERCLIS List 0.5 Federal CERCLIS NFRAP List 0.5 Federal RCRA TSD Facilities List 0.5 Federal RCRA Generators Lists 0.25 Federal CORRACTS list 1.0 Federal ERNS list Target Property US Engineering /Institutional Controls Lists 0.5 US Brownfields List 0.5 EPA Consent Decree List 1.0 EPA Record of Decision List 1.0 State Hazardous Waste Site List 1.0 State Landfill and /or Solid Waste Disposal Site List 0.5 State Leaking UST List 0.5 State Registered UST List 0.25 State Spills List Target Property State Brownfields List 0.5 Indian Sites Lists 0.5 Manufactured Gas Sites 1.0 ADDITIONAL ENVIRONMENTAL RECORDS Additional state or local database listings will be reviewed as deemed appropriate. A comprehensive review of Indiana and /or federal regulatory files is beyond the scope of this Phase I Update effort, although as deemed necessary, Wightman Petrie may initiate a Freedom of Information Act Request Hamilton Body Shop /Hamilton Towing March 27, 2012 Page 4 of 10 through the Indiana Department of Environmental Management (IDEM) Central File Room, or access pertinent information made available through the Virtual File Cabinet. PHYSICAL SETTING SOURCES A United States Geological Survey (USGS) 7.5 Minute Topographic Map will be reviewed to evaluate area topographic and surface drainage. At least one (1) additional physical setting source will be reviewed for information on the geologic, hydrogeologic, hydrologic, or topographic characteristics of the site. HISTORICAL USE INFORMATION The purpose of consulting historical sources is to develop a history of the previous uses or occupancies of the site, and surrounding area, in order to identify those uses, or occupancies that are likely to have led to recognized environmental conditions in connection with the subject site. USES OF THE SUBJECT PROPERTY Prior uses of the subject site will be identified from the present, back until at least the period of initial development using the available "standard historical resources" listed below: Aerial Photographs Fire Insurance Maps Property Tax Files Recorded Land Title Records USGS 7.5 Minute Topographic Maps Local Street Directories Our proposal does not include a Chain -of -Title search. If others have recently completed a Chain -of- Title, Wightman Petrie will review the document for potential environmental concerns associated with prior ownership. USES OF PROPERTY IN SURROUNDING AREAS Using available resources, the history and /or general uses of properties in the surrounding area will be researched at a search distance and time period deemed appropriate given the findings of other portions of the assessment. Complete coverage using local street directories, Sanborn Fire Insurance Maps and potentially other historical records regarding the prior uses of the subject site and surrounding properties may be limited, may not be readily available, or may not even exist for purposes of review. SITE RECONNAISSANCE The purpose of the site reconnaissance is to observe current conditions at the site and obtain information indicating the likelihood of environmental concerns with the site. A reconnaissance will be performed for indications of waste handling or disposal activities that may pose a hazard to the subsurface environment. We will require access to all areas, to the extent they are not obstructed by bodies of water, adjacent buildings, or other obstacles. We have assumed that access to all parcels and existing structures can be coordinated within a single mobilization. Unforeseen circumstances notwithstanding, only one (1) site visit will be made. INTERVIEWS Interviews will be conducted with knowledgeable persons to obtain direct, personal information regarding activities and /or operations which may have affected the environmental condition of the site. Selected local Hamilton Body Shop /Hamilton Towing March 27, 2012 Page 5 of 10 regulatory and /or emergency response officials may also be interviewed regarding knowledge of past or present environmental problems or emergency responses at the site. IDENTIFICATION OF DATA GAPS Depending on the availability of certain resources for evaluating historical property use, previous property owners (for interview) and other pertinent information; certain "Data Gaps" may be identified within our Report. Wightman Petrie will make determinations as to the potential impacts such Data Gaps have on conclusions as to the presence or potential presence of recognized environmental conditions. PHASE I ENVIRONMENTAL SITE ASSESSMENT UPDATE REPORTING Upon completion of our site reconnaissance, regulatory database and historical records review, a verbal summary will be presented. Our written report of findings will include documentation to support the analysis, opinions and conclusions found in the report, inclusive of referenced sources. Based upon the observations made during the Phase I reconnaissance, modifications to the Phase II Proposed Scope of Services may be warranted. TASK 2 — Ground Penetrating Radar Prior to the initiation of any Phase II Environmental Site Assessment activities, Wightman Petrie proposes to conduct a Ground Penetrating Radar Survey of the 802 -812 S. Lafayette Blvd. property, as well as the 901 -917 S. Lafayette Blvd. property for the purpose of determining whether UST systems remain in the ground. As indicated from the prior Phase I Site Assessment Reports, the removal status of certain historical UST systems could not be verified, and at least one (1) additional UST system is thought to remain in the ground (as indicated by the presence of a vent pipe on the side of the building at 901 -917 S. Lafayette Blvd.). Ground Penetrating Radar (GPR) offers the means to detect buried objects that are not otherwise detectable. In addition to the ability to locate metal objects (i.e., underground storage tanks, drums), GPR is able to detect non - metallic objects. The system sends radar pulses into the surface, receives, and processes the reflected energy. Through advanced processing technology, the system calibrates the di- electric constant of the surrounding material. When the signal is reflected from the material having a different di- electric constant, the signal is displayed on the screen as an anomaly. Depth can also be determined by processing the sampling interval and determining the size and comparing relative data to other objects detected. Characteristics of underlying soils effect the penetration of the radar through the ground. Sands and gravel offer the greatest depth penetration and clearest resolution. Whereas, dense saturated clays offer limited penetration of the radar signal. For purposes of this proposal, Wightman Petrie has assumed a depth limitation for the GPR of approximately 8 feet below land surface. Areas of the suspect former UST system location(s) will be scanned by GPR and delineated using varying interval grid patterns. Multiple scans in a north -south and east -west direction will be performed utilizing the GPR, looking for anomalies. Any identified anomalies (i.e., disturbed subsurface soils) will be marked on the surface using paint, as appropriate for utility locators and for soil boring locations by Wightman Petrie. TASK 3 - Soil Sampling via Geoprobe Methodology Using Geoprobe methodologies (small track mounted hydraulically driven sampling probe) soil samples will be collected from a total of nineteen (19) locations. Boring locations will be determined based upon the results of historical document review and field data gathered from the prior Phase I Site Assessments, Phase I Updates and completion of the Ground Penetrating Radar Surveys. In general, Wightman Petrie would propose to install at least four (4) soil borings across the 802 -812 S. Lafayette Blvd. property, with specific emphasis on the area of former USTs and stained soils associated with releases from wrecked Hamilton Body Shop /Hamilton Towing March 27, 2012 Page 6 of 10 autos. Two (2) hand auger borings are also proposed in the general area of the former underground hoist system. Five (5) soil borings are proposed across the 910 -912 S. Lafayette Blvd. property, with emphasis on the areas of hazardous and petroleum storage, trench drains, ASTs, and historical car repair. For the 901 -917 S. Lafayette Blvd. property, ten (10) soil borings are proposed with emphasis on the former USTs, ASTs, paint shop, drum storage, and stained soils associated with releases from wrecked autos. For each of the Geoprobe boring locations, discrete soil samples will be collected at 5 -foot intervals throughout the soil profile until saturated soil conditions are encountered (assumed to be approximately 25 feet below land surface). Each soil sample interval will be screened for the presence of volatile organics by placing a portion of the soil sample into a plastic bag, allowing time for equilibration, and insertion of a photoionization detector (PID) probe to observe a reading of "total VOCs" in parts per million (ppm). All data associated with the field screening of VOCs will be recorded for future reference (Soil Boring Logs). In addition, a portion of each discrete sampling interval will also be collected for submittal to a laboratory. Wightman Petrie proposes to submit one (1) soil sample from each of the nineteen (19) boring locations based on the PID field screening results and /or other indications of the presence of potential contamination (visual or olfactory). In the event that field screening with a PID, visual or olfactory observations do not indicate the presence of contamination; the soil sample collected from the upper two (2) feet within the boring, will be submitted for laboratory analysis. We note that the area of the subject site is serviced by municipal water and sanitary sewer; therefore direct contact through the use of groundwater as a potential pathway for exposure has been eliminated, and therefore direct contact via contaminated surface soils becomes an over - riding concern. Each of the soil samples selected for laboratory analysis will be analyzed for the presence of Volatile Organic Compounds (VOCs) via EPA Method 8260. Most soil samples identified for laboratory analyses will also be analyzed for the presence of carcinogenic Polynuclear Aromatic Hydrocarbons (cPAHs) via EPA Method 8270 (Selective Ion Methodology); however, some will be analyzed for the presence of Total Petroleum Hydrocarbons, Extended Range Organics (TPH -ERO) as an indicator of the presence of significant petroleum contamination. Wightman Petrie will utilize IDEM guidance Terra -Core Methods to collect soil samples from each discrete sampling interval for the analysis of VOC constituents. All soil samples will be labeled, packed on ice and forwarded to the laboratory under chain -of- custody procedures. TASK 4 - Temporary Geoprobe Well Installation for Groundwater Sampling Wightman Petrie proposes to convert a minimum of seven (7) Geoprobe soil borings to temporary wells with insertion of a Geoprobe groundwater sampling device, which allows for the extension of a stainless steel slotted screen for collection of a groundwater sample from the point at which the saturated or water - bearing zone is encountered. For this proposal, Wightman Petrie has assumed that the water - bearing zone will be encountered within 25 -feet of land surface. Once installed, each temporary well would be purged until such time as the water discharge becomes relatively free of solids or until at least three (3) gallons of water have been removed. Wightman Petrie proposes that groundwater from each of the temporary wells be analyzed for Volatile Organic Compounds via EPA Method 8260, and carcinogenic PAHs via EPA Method 8270 SIM. For those temporary wells at which multiple groundwater samples will be collected (total of four); Wightman Petrie proposes that the groundwater sample from the deeper of the screened intervals be analyzed for the presence of VOCs only. Each groundwater sample will be appropriately labeled, packed on ice, and forwarded to the laboratory (priority overnight delivery) under chain -of- custody procedures. Analysis will also include the analysis of a water sample for QA/QC purposes (Volatile Organic Compound only). Wightman Petrie will plug the boreholes /wells with bentonite once soil and groundwater sampling activities have been completed. Hamilton Body Shop /Hamilton Towing March 27, 2012 Page 7 of 10 :14001:41111►f0 Upon receipt of the laboratory analyses, data will be reviewed and tabularized. Comparison of the data for each respective chemical constituent will be made to the Risk Integrated System of Closure (RISC) Default Closure Values for Residential and Industrial /Commercial Properties. Upon completion of the initial data review, a "Letter Report" will be prepared which presents the sample collection and analytical methodologies used during the field phase of the assessment. Copies of the sample location maps, tabulated data and comparison to RISC Default Closure Values will also be incorporated. Recommendations for any additional assessment activities will be made for review and comment. TASK 5 — Dye Trace for existing Trench Drains Depending on whether or not the identified trench drains within the buildings present at the 910 -912 S. Lafayette Blvd. and 901 -917 S. Lafayette Blvd. properties are free flowing; Wightman Petrie may be able to determine the location of discharge through the introduction of a biodegradable dye. We note that if the drains are not free flowing, and tend to back -up, then introduction of the biodegradable dye serves no purpose. At that point, it becomes more logical to wait until demolition of the building, as opposed to incurring the expense of drain cleaning. Should the drain system be confirmed as free flowing, the direction of flow of the existing municipal sanitary sewer must be determined, and an immediately downgradient manhole opened for observation. Once free flow, and a point of observation are established, the dye is introduced to the trench drain, and its presence (after delay) is documented as present, or absent, within the downgradient manhole flow. If absent, then other potential points of discharge other than the municipal sanitary sewer system exist, and should be investigated for the presence of potential contamination. SCHEDULE Wightman Petrie proposes to commence site investigation activities within one (1) week of receipt of notification to proceed, depending on weather, utility clearance and Geoprobe availability. Our Ground Penetrating Radar Survey work will be completed prior to the initiation of soil boring installation activity, and can commence immediately following the receipt of Authorization to Proceed. Once a specific date for the field component of the Phase II has been established, Wightman Petrie will notify the client. Upon mobilization, we anticipate completion of the Geoprobe sampling requiring two (2) days, although a third day may be necessary depending on the actual depth to groundwater. Laboratory analyses will be completed by Pace Analytical on standard one -week turnaround from receipt by the laboratory. Our initial discussion of results will occur within three (3) days of receipt of all laboratory analytical results. Our written "Summary Letter Report" will be submitted within two (2) weeks of the initial conference. COST ESTIMATE An ESTIMATED COST for Scope of Services, as presented herein, is summarized below. Please note that the Estimated Costs for the Phase II Reporting is based upon the submittal of a single Phase II Environmental Site Assessment Report, as opposed to property specific Phase II Reports.

However, should the scope of services require modification (i.e., additional borings) based upon field conditions and /or circumstances that would not have otherwise been anticipated, Wightman Petrie will notify the client of such "changed conditions" and resultant cost implications to the project. LIMITATIONS /QUALIFICATIONS The sampling and testing of soil, groundwater and /or other materials not specifically identified in this proposal is beyond the scope of services for this project. Cost estimates for our proposed services have been prepared based on the following assumptions: • Wightman Petrie will have unlimited access to the site during daylight hours; • No subsurface obstructions (buried utilities or fill debris) will interfere with our work; • Sufficient access /clearance will be provided for interior and exterior Geoprobe locations; • Groundwater will be encountered within 25 -feet of ground surface; Hamilton Body Shop /Hamilton Towing March 27, 2012 Page 9 of 10 • Inclement weather will not interfere with the completion of our field work; • Soil cuttings and purge waters will be returned to the boring from which they were generated, with the remainder of the boring filled with bentonite pellets to land surface. This Phase II Environmental Site Assessment should be considered as a "tool' in the evaluation of the subject site relative to the potential presence of contaminants, and does not necessarily fulfill Indiana Department of Environmental Management (IDEM) guidelines for delineation of contaminants identified within soil or groundwater as required under UST Closure Guidelines.
