Phase II — Troeger site at Jefferson & Niles Date: September 13, 2011 The attached Professional Services Agreement is a proposal from Wightman Petrie Inc. (WPI) for a Phase II site assessment at the former Troeger Sheet Metal site at Jefferson & Niles. This site is bounded by Washington on the north, Niles to the west, Jefferson on the south, and the north / south alley to the east. In 2010 the Commission approved a Phase I for this site, which was acquired later that year. As was noted in this Phase I, there was a Recognized Environmental Condition caused by leakage from the former 6,000 gallon underground storage tank (UST). When this UST was removed in 2003, the levels of certain petroleum based chemicals were above residential levels. No soil testing has been completed since. On June 28, 2011, the Commission approved an Agreement for Sale of Land for Private Development for this site. This development will include residential town homes. Because the soil has not been tested for approximately eight years, and because of this sites proximity to the river, it is possible the chemical levels are now below residential levels. To determine chemical levels now, and where exactly they may be, a Phase II is needed. This Phase II will encompass a Ground Penetrating Radar Survey; four Geoprobe soil samples, with two soil samples from each being tested; and a Geoprobe well installation for ground water testing. Total project services cost is a not to exceed of $6,535. Staff requests approval of this Professional Services Agreement, to allow a Phase II environmental site assessment to be completed to determine the current status of this property. What We Do Today Makes A Difference! August 30, 2011 City of South Bend Community and Economic Development 227 West Jefferson Boulevard South Bend, Indiana 46601 Attention: Mr. David Relos, Economic Development Planner RE: PROPOSAL FOR PHASE II ENVIRONMENTAL SITE ASSESSMENT FOR THE FORMER TROEGER SHEET METAL SITE, NILES AVENUE AND WASHINGTON STREET, SOUTH BEND, INDIANA, PROPOSAL NUMBER WP 11 -040 Dear Mr. Relos: Wightman Petrie is pleased to provide the following Proposal for Phase II Environmental Site Assessment Services associated with the area historically identified as the Troeger Sheet Metal property. The following presents a review of the background information. as well as the proposed scope of such recommended services, project schedule and estimate of costs. PROJECT INFORMATION The Former Andrew Troeger and Company lots (subject site), consist of eight (8) contiguous land parcels, all of which are located along S. Niles Avenue (which serves as the western property boundary), between E. Washington Avenue to the north, and E. Jefferson Boulevard to the south, with the eastern property boundary being the north /south alleyway present between S. Niles Avenue and S. Hill Street, to the east. The subject site currently serves as a parking lot (portions paved and portions gravel covered) for area businesses and weekend recreational events associated with the East River Race. More recent structures on the subject property were demolished as of 2003/2004. Such structures included a small retail store (bagel shop) at 511 E. Jefferson Blvd., and a warehouse and sheet metal fabrication shop ( Troeger Sheet Metal), with an office fronting S. Niles Avenue, at 122 S. Niles Ave. A Phase I Environmental Site Assessment performed in 2010 by Phifer Environmental Services, LLC for the City of South Bend identified the following Recognized Environmental Condition: 1) The historical removal (2003) of a 6,000- gallon heating oil UST system for which post excavation samples were analyzed and revealed TPH (2,200 ppm) and Benzo (a) pyrene (590 ppb) concentrations in excess of applicable state guidelines (RISC Residential) is identified as a Historical Recognized Environmental Condition. We note that a subsequent site screening investigation (2003) involving the collection of 30 soil samples did not reveal the presence of TPH w� WIGHTMA ETRIE SURVEYING ENGINEERING FNVIRONMFNTAL LANDSCAPF ARCHITECTURE 112 S. Lafayette Blvd. ° South Bend IN 46601 p: 574.232.4388 E 574.232.4333 David Relos August 30, 2011 Page 2 of 6 concentrations above 100 ppm (two (2) samples analyzed), which was the applicable guideline of the period. However, Benzo (a) pyrene concentrations of 590 ppb and 680 ppb, as reported in the supplemental screening assessment, continued to be above the current RISC Residential criteria of 500 ppb. We also note that the reported Benzo (a) pyrene concentrations were below the RISC Industrial criteria of 1,500 ppb. Although noting that heating oil UST systems used strictly for on -site consumption (as was the case) are exempt from UST requirements; the presence of soil contamination in excess of the RISC Residential criteria could be considered as an indicator of the presence of petroleum contamination, the extents of which were not clearly defined by the 2003 removal sampling or the 2003 supplemental assessment. As such, the possibility exists that any future re- development of the subject site may potentially encounter contaminated soils that may require additional excavation. Phifer Environmental also noted that historical buildings associated with the subject site were known to have heating oil systems, the status of which could not be confirmed. Such UST systems would also be exempt from UST regulations based upon their historical, on -site consumptive use (i.e., 511 Jefferson Blvd.) Phifer Environmental recommended that if during re- development of the property, additional heating oil UST systems or petroleum contaminated soils from historical heating oil systems are encountered, actions for their removal should be undertaken. We note that the City of South Bend and Mr. David Matthews (developer) have reached a tentative Purchase Agreement for the sale of the subject site for the future development of condominium units similar to those being constructed for the nearby, former Rink Riverside site. However, as part of the due diligence process, the City of South Bend and Mr. Matthews are interested in further assessment of the former UST area to determine the extent to which, if any, remnant petroleum impacted soils and /or groundwater remain in the general area of the former heating oil UST location. PROPOSED SCOPE OF SERVICES Ground Penetrating Radar Survey Prior to the initiation of any Phase II Environmental Site Assessment activities, Wightman Petrie will review the prior Phase I Environmental Site Assessment and UST Closure documentation with respect to the location of the former 6,000- gallon former heating oil UST system. Once a general area for the former UST system has been identified, Wightman Petrie will utilize Ground Penetrating Radar as a means for trying to confirm a more exacting location (i.e., presence of disturbed subsurface soils, existing debris associated with UST piping systems, concrete saddles, etc.). 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 David Relos August 30, 2011 Page 3 of 6 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 former UST system 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. Soil Sampling via Geoprobe Methodology Using Geoprobe methodologies (small track mounted hydraulically driven sampling probe) soil samples will be collected from a total of four (4) locations. Boring locations will be determined based upon the results of historical document review and field data gathered from the completion of the Ground Penetrating Radar. In general, Wightman Petrie would propose to install one (1) soil boring within the centralized area of the former tankpit, one (1) soil boring upgradient of the former tankpit, and two (2) soil borings downgradient of the former tankpit. 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 10 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 photo ionization 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 two (2) soil samples from each of the four (4) 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 two (2) depth intervals immediately above the soil /groundwater interface will be submitted for laboratory analysis. Each of the soil samples selected for laboratory analysis will be analyzed for the presence of Benzene, Ethylbenzene, Toluene, Xylene (BTEX) constituents, Methyl -tert-butyl Ether (MTBE), N- Heaxane and Naphthalene via EPA Method 8260, Total Petroleum Hydrocarbons — Extended Range Organics (TPH -ERO) via EPA Method 8015M, and carcinogenic Polynuclear Aromatic Hydrocarbons (cPAHs), in accordance with IDEM guidance for kerosene and other similar heating oils. Wightman Petrie will utilize IDEM guidance Terra -Core Methods to collect soil samples from each discrete sampling interval for the analysis of BTEX constituents. All soil samples will be labeled, packed on ice and forwarded to the laboratory under chain -of- custody procedures. Temporary Geoprobe Well Installation for Groundwater Sampling Wightman Petrie proposes to convert each of the four (4) 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 20 -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 has 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. Each groundwater sample will be appropriately labeled, packed on ice, and forwarded to the laboratory (priority David Relos August 30, 2011 Page 4 of 6 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. Reporting 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. 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. 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 one (1) day. Should less field time (i.e., 'h -day of Geoprob) be required; you will be billed accordingly. 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 one (1) day of receipt of laboratory analytical results. Our written "Summary Letter Report" will be submitted within one (1) week of the initial conference. COST ESTIMATE An ESTIMATED COST for Phase II Environmental Assessment Services is presented as follows: Field Engineering Services /Project Management Limited Ground Penetrating Radar Survey Geoprobe Rental (assumes 1 -day @ $1,400 /day, including mobilization) Laboratory Analysis: 8 soil samples for % Moisture @ $10 /sample 8 soil samples for analysis of BTEX constituents @ $65 /sample 8 soil samples for analysis of TPH -ERO @ $60 /sample 8 soil samples for analysis of carcinogenic PAHs @ $90 /sample 5 groundwater samples for analysis of Volatile Organics @ $95 /sample 4 groundwater samples for analysis of carcinogenic PAHs @ $90 /sample Reporting ESTIMATED COST $900 $300 $1,500 $80 $520 $480 $720 $475 $360 $1,200 $6,535 Please note that this ESTIMATED COST should be considered a Project Maximum, which Wightman Petrie will not exceed without prior approval. 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. David Relos August 30, 2011 Page 5 of 6 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 exterior Geoprobe locations; • Groundwater will be encountered within 20 -feet of ground surface; • 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.
