3 EXECUTIVE SUMMARY Purpose Timmermans Environmental Services, Inc. (TES) has completed the Phase 2 Environmental Site Assessment (ESA) for the fuel station located at & 1159 Wyoming Street, Detroit MI The purpose of the Phase 2 ESA was to investigate the potential for contaminant impact to soil and/or groundwater from the RECs identified in the Phase 1 ESA. The property is approximately 22, square feet in size. An approximate 1,88 square foot building is located on the west side of the property. Exterior walls consist of concrete blocks. An overhead, steel canopy is located to the east of the building over four pump islands. Sanitary sewer utilities are provided by the city of Detroit. Incoming natural gas meters are located on the west side of the building and electrical utilities also enter overhead from utility poles located on the west side of the property. Plymouth Road is located to the north of the property and Wyoming Street runs on the east side of the property. A Phase 2 subsurface investigation was initiated by TES on April 1, 213. The subsurface investigation consisted of the advancement of nine soil borings (SB-1 through SB-9), the installation of two temporary monitoring wells at SB-4 and SB-8, and the collection of groundwater from tank monitoring well TM-1 for the collection of soil and ground water samples for laboratory analysis. The Phase 2 ESA activities were performed to assess the RECs identified in the Phase 1 ESA completed for the site in April 213. Based upon the results of the Phase 2 ESA, TES makes the following conclusions and recommendations: Conclusions Results of the Phase 2 ESA indicate no soil impact above the Tier 1 RBSLs at the subject site with the exception of lead at SB-8. However, the lead value at SB-8 is below the Commercial Direct Contact RBSL. TES professional opinion is that the lead value is indicative of background levels of lead found in urban settings and does not pose a threat at the commercial subject property. Results of the Phase 2 ESA indicate that no groundwater contamination is present above the Tier 1 RBSLs with the exception of lead at temporary monitoring points SB-4 and SB-8. However, due to sampling methods, residual sediment in the sampled water may contribute to higher levels of lead than are indicative of normal levels of lead in the groundwater. The subject property is located in an urban setting and relies on the City of Detroit for potable water. Therefore, this exceedance does not pose a threat to the subject property. Recommendations TES recommends no further action at this time. Timmermans Environmental Services Page 1

6 Section 1 Purpose Timmermans Environmental Services, Inc. (TES) completed a Phase 2 Environmental Site Assessment (ESA) for the fuel station located at & 1159 Wyoming Street, Detroit MI A site location map with sampling locations is shown as Figure 1. The purpose of the Phase 2 ESA was to investigate the potential for contaminant impact to soil and/or groundwater from Recognized Environmental Conditions (RECs) identified in the TES Phase 1 ESA dated April 8, 213. The following RECs were identified by TES in the Phase 1 ESA: 1) The current UST system was installed in 21. Multiple compliance failures are identified from MDEQ Facility Inspection Reports. On-site soil and groundwater have not been investigated in detail. The age of the current UST system and the compliance issues indicate that an un-detected release may have occurred since 21. Therefore, the current UST system represents evidence of a REC. 2) The lack of official State records for historic USTs and the length of history of the site operations as a gasoline service station indicate that knowledge of all historic USTs may not be complete. Several gasoline and non-gasoline USTs, such as used oil and kerosene USTs, have historically existed on the subject property. It is possible that un-detected contamination from these historic USTs may exist on the subject property. Therefore, the historical USTs represent evidence of a REC. 3) The subject site is listed in the EDR Historical Auto Station database for the years 1965, 197, 27, 21, 211, and 212. The site is also visible on Sanborn fire insurance maps and indicated as a service station at least during the years and Automotive maintenance and repair activities occurred on the property during a time frame when the handling and disposal of chemicals and petroleum products were not strictly regulated or enforced. Historical interior waste streams associated with the service station may have consisted of general hazardous substances and/or petroleum products, including but not limited to used motor oils, transmission fluids, antifreeze, and mineral spirits. The potential exists that a release may have occurred from former hydraulic hoist systems and/or underground reservoirs. In-ground hoists have an underground reservoir for hydraulic fluids, which can contain PCBs. The installed hoists could have been installed as a part of the historic automotive service operations at the property. Therefore, the historic use of the site as an auto service station represents evidence of a REC. 4) The subject property acted as a Cleaning and Pressing operation from approximately 195 until Historical interior waste streams associated with the Cleaning and Pressing service may have consisted of general hazardous substances and/or petroleum products. Therefore, the historic use of the site as Cleaning and Pressing service represents evidence of a REC. Timmermans Environmental Services Page 4

7 5) Open LUST incidents exist on adjacent properties to the north and east of the subject property. The proximity of and up-gradient position of the two LUST incidents pose a potential threat to the subject property and therefore represent evidence of an REC. 6) TES was unable to determine the size, location, and contents of the former USTs associated with the original service station development. USTs associated with the development may have included gasoline USTs, diesel USTs, fuel oil USTs, and waste oil USTs. The potential exists for orphan USTs to be present on the property and/or for a release of to have occurred from the former UST systems. Section 2 Site Description The property is approximately 22, square feet in size. An approximate 1,88 square foot building is located on the west side of the property. Exterior walls consist of concrete blocks. An overhead, steel canopy is located to the east of the building over four pump islands. Sanitary sewer utilities are provided by the city of Detroit. Incoming natural gas meters are located on the west side of the building and electrical utilities also enter overhead from utility poles located on the west side of the property. Plymouth Road is located to the north of the property and Wyoming Street runs on the east side of the property. The site property is located in the East 1/2 of the Northeast 1/4 of Section 32, Township 1 South, Range 11 East in Wayne County Michigan. The property lies at an elevation of 628 feet above sea level. The Rogue River is located approximately 4.8 miles to the west of the subject site. Section 3 Previous Investigations No previous investigations were provided to TES prior to the completion of the April 8, 213 Phase 1 ESA. Section 4 Site Investigation A subsurface investigation was initiated by TES on April 1, 213. The subsurface investigation consisted of the advancement of nine soil borings (SB-1 through SB-9), the installation of two temporary monitoring wells at SB-4 and SB-8, and the collection of groundwater from tank monitoring well TM-1 for the collection of soil and ground water samples for laboratory analysis. A total of ten soil and three groundwater samples were collected from the site and submitted to ALS Laboratories in Holland Michigan, for laboratory analysis of gasoline, diesel, and waste oil indicating parameters. The contaminants of concern include VOCs from the EPA 826b list. Waste oil indicating parameters include volatile organics, lead and PNAs. The soil borings were drilled in order to investigate the RECs identified in the Phase 1 ESA. Soil samples and their associated analyses are listed in Tables 1 and 2. Groundwater samples and their associated analyses are listed in Tables 3 and 4. The soil boring locations are shown in Figure 2. The soil boring logs are included in Appendix A. Timmermans Environmental Services Page 5

8 Prior to the site investigation MISS Dig public utility locator was contacted to located utilities on or near the site property. In addition, a private utility locating service was contracted to identify site specific utilities on site. A hand augur or air knife was utilized to clear specific soil boring locations. No free product was encountered during this investigation. Soil Sampling Methods Soil borings were completed by direct-push methods using a truck mounted Geoprobe TM 66 equipped with a macro core sampler. This method also provides continuous soil samples in 5- foot sample-tube intervals. However the upper 4-7 feet of each boring was hand augured or air knifed for protection of the utilities and for safety purposes. The boring logs describing the soil conditions and sampling details are attached in Appendix A. Soils collected from two-foot sample intervals were screened using a Phocheck photo-ionization detector (PID) to determine if VOCs were present. Soil from specific depths were placed in plastic bags or sample jars, sealed, and allowed to volatilize. The headspace within each bag or jar was then monitored with the PID. The PID is able to detect trace levels of organic compounds in the air space within the plastic bag. The PID utilizes a 1.6 electron volts (ev) lamp. Soil samples were collected from the soil borings based upon the highest PID reading, visual/olfactory evidence, a change in geology, surficial soil, and/or directly above saturated soil. The results of the headspace analyses are presented on the attached boring logs in Appendix A. Groundwater Sampling Methods Temporary ground water sampling points were installed at two of the soil boring locations (SB-4 and SB-8). A third groundwater sample was collected from an existing tank monitoring well TM-1. The ground water samples collected from the monitoring wells were collected using polyethylene tubing connected to a peristaltic pump. Prior to sampling, the well was purged until relatively clear of sediment. After ground water sampling was completed at SB-4 and SB-8 the Geoprobe sampling screen was removed from the ground and the borehole was backfilled with bentonite chips and/or cuttings. Laboratory Analysis Soil samples were collected for analysis of volatile organic compounds (VOCs) from each boring in accordance with U.S. EPA method 535. One portion of each sample was placed in a vial that contained methanol preservative for high level analysis and another portion was placed in two vials that contained sodium bisulfate preservative for low level analysis. Soil sample bottles also included a 4-oz jar with no preservative. The ground water sample collected for analysis of VOCs was preserved with HCl at the time of collection. The soil and groundwater samples were labeled, placed in ice packed coolers, and transported to ALS Environmental in Holland, MI for analysis. A chain of custody was filled out and transported with the samples. Samples were extracted and analyzed within applicable holding times. The soil and groundwater samples were analyzed for State of Michigan unleaded gasoline compounds, including benzene, toluene, ethylbenzene, xylenes (BTEX), methyl tert-butyl ether Timmermans Environmental Services Page 6

9 (MTBE), naphthalene, 2-methylnaphthalene, 1,2,4-trimethylbenzene and 1,3,5-trimethylbenzene (TMBs) in accordance with U.S. EPA Method SW826, and svoc compounds utilizing Method SW827. The results of the analyses are summarized on Tables 1 through 4, and include a comparison of the results to Michigan Part 213 Risk-based Screening Levels (RBSLs). The laboratory reports are attached in Appendix B. Soil samples submitted for laboratory analysis were chosen based on likely source depths, PID readings, and/or visual/olfactory evidence of contamination. The compounds analyzed and USEPA methods are summarized in the table below. Analytical Methods COMPOUNDS VOCs svocs Metals USEPA METHOD Soil: SW535/826B SW827 SW62A/SW35B USEPA METHOD Groundwater: SW826B SW827 SW35A Section 5 Results Geology Bedrock geology for the site is described in Geology of the Conterminous U.S. (1974) as being Stratified Sequence of Middle Devonian Age. Estimated depth to bedrock is 15 feet. The U.S. Department of Agriculture s (USDA) provides information regarding soil surveys based on the Soil Conservation Services STATSGO data. The primary soil classification is Urban land. Soil surface types described in the general area of the target property include clay loam, loamy fine sand, and loamy sand. The soil encountered at the site consists primarily of native clay. Sand and gravel fill exist in variable amounts at each boring location as described on the attached soil boring logs in Appendix A. The portion of the site not occupied by the retain convenience store is covered primarily with asphalt or concrete. The results of the headspace tests performed on the soil samples showed no or low readings at each of the borings. The PID readings are recorded on the attached soil boring logs in Appendix A. Hydrogeology Based on regional topography and physical setting, site groundwater flow with the near surface sediments is assumed to follow topography and would likely flow to the west southwest and would likely flow toward the Rogue River located approximately 4.8 miles to the west of the Timmermans Environmental Services Page 7

10 site. Such local water bodies likely act as a discharge point for shallow groundwater in the vicinity. Water was encountered across the site at approximately 1-6 feet bgs. However, this water was primarily discovered in near surface fill and soils and may not reflect an occurrence of actual groundwater. Further testing would be required to determine if the water is representative of water collected in fill material or if it is indicative of groundwater. Two temporary monitoring wells were installed at the subject property during the Phase 2 investigation at SB-4 and SB-8. A third water sample was collected from an existing tank monitoring well TM-1. Summary of Soil and Groundwater Analytical Results No free product was encountered during this investigation. Ten soil samples were submitted for laboratory analysis. The results for the soil samples are summarized in Table 1 and 2. The complete laboratory report is attached in Appendix B. The analytical results of the soil samples indicate no target VOC or svoc compounds were detected. The soil sample from SB-8 exceeded the State of Michigan Residential Direct Contact RBSL for lead, but was below the Commercial Direct Contact RBSL. Three groundwater samples were submitted for laboratory analysis. The results for the groundwater samples are summarized in Tables 3 and 4. The analytical results of the groundwater samples indicate no target VOC or svoc compounds were detected with the exception of benzene and xylene at TM-1 which were below the State of Michigan RBSLs. Analytical results of the groundwater samples collected from temporary monitoring points at SB- 4 and SB-8 indicate lead exceeds the Residential Drinking Water RBSL. The complete laboratory report is attached in Appendix B. Exposure Pathway Evaluation A Tier I evaluation was conducted for the gas station petroleum release consistent with the procedures outlined in ASTM International Standard Guide for Risk-Based Corrective Action Applied at Petroleum Release Sites E (Reapproved 21). Information and data collected during site assessment activities were utilized to conduct an exposure pathway evaluation, to verify the applicability of the relevant Tier I Residential RBSLs established by the MDEQ under Part 213, and to conduct a comparison of the maximum chemical concentrations to the relevant Tier I RBSLs. No complete exposure pathways have been identified based on current site use and reasonably expected future site use. The following sections discuss the analytical results for each REC by comparing the results to Tier 1 RBSLs for each constituent analyzed and the remediation objectives for each exposure Timmermans Environmental Services Page 8

11 pathway. Tables 1 through 4 list the relevant Tier I Residential RBSLs for soil and groundwater for lead, VOCs and svocs. Nine locations were selected for soil sampling (see Figure 2). Individual RECs and associated soil borings are addressed in the section and table below: REC Soil Borings #1 Current UST System SB-1, SB-2, SB-3, SB-4, SB-5, SB-6, SB-7 #2 Historic UST Systems SB-1, SB-2, SB-3, SB-4, SB-5, SB-6, SB-7 #3 Historic Auto Service SB-1, SB-2, SB-3, SB-4, SB-5, SB-6, SB-7, SB-8, SB-9 #4 Historic Cleaning & Pressing SB-1, SB-2, SB-3, SB-4, SB-5, SB-6, SB-7 #5 Adjacent Open LUST Sites SB-1, SB-2, SB-4, SB-5, SB-6 #6 Potential Orphan Tanks SB-1, SB-2, SB-3, SB-4, SB-5, SB-6, SB-7, SB-8, SB-9 REC 1: Current Retail Fuel Operations The current UST system was installed in 21. Multiple compliance failures are identified from MDEQ Facility Inspection Reports. On-site soil and groundwater have not been investigated in detail. The age of the current UST system and the compliance issues indicate that an un-detected release may have occurred since 21. Therefore, the current UST system represents evidence of a REC. Samples from the following locations were used to evaluate this REC: SB-1, SB-2, SB-3, SB-4, SB-5, SB-6, and SB-7 Soil: Drinking Water Protection Exposure Pathway. The following constituents exceed the applicable Tier 1 RBSLs for the Drinking Water Protection Exposure Pathway: Lead at the SB-4 temporary monitoring well exceeds the Residential Drinking Water RBSL. Water was collected from the temporary monitoring point at SB-4 using a peristaltic pump and low flow techniques. An attempt was made to purge the collected water of sediment prior to sample collection. However, complete removal of sediment from a temporary monitoring point is generally not possible. As a result, residual sediment in the sampled water may contribute to higher levels of lead than are indicative of normal levels of lead in the groundwater. In addition, the groundwater sample collected from the existing tank monitoring wells did not contain detectable levels of lead. The subject property is located in an urban setting and relies on the City of Detroit for potable water. Therefore, this exceedance does not pose a threat to the subject property.

Several gasoline and non-gasoline USTs, such as used oil and kerosene USTs, have historically existed on the subject property. It is possible that un-detected contamination from these historic USTs may exist on the subject property. Therefore, the historical USTs represent evidence of a REC. TES was unable to determine the size, location, and contents of the former USTs associated with the original service station development. USTs associated with the development may have included gasoline USTs, diesel USTs, fuel oil USTs, and waste oil Timmermans Environmental Services Page 1

A GPR survey was performed by the Underground Detective out of Toledo, Ohio. The entire property, except for the area covered by the building and UST infrastructure, was surveyed for the purpose of identifying any orphan USTs on the subject property. No such buried objects were identified during the survey.

However, the lead value is below the Commercial Direct Contact RBSL. TES professional opinion is that the lead value is indicative of background levels of lead found in urban settings and does not pose a threat at the commercial subject property. REC 3: Historical Auto and Service Station The subject site is listed in the EDR Historical Auto Station database for the years 1965, 197, 27, 21, 211, and 212. The site is also visible on Sanborn fire insurance maps and indicated as a service station at least during the years and Automotive maintenance and repair activities occurred on the property during a time frame when the handling and disposal of chemicals and petroleum products were not strictly regulated or enforced. Historical interior waste streams associated with the service station may have consisted of general hazardous substances and/or petroleum products, including but not limited to used motor oils, transmission fluids, antifreeze, and mineral spirits.

The following constituents exceed the applicable Tier 1 RBSLs for the Groundwater Contact Exposure Pathway: Lead at SB-8 (1-2 ). Lead exceeds the Residential Direct Contact RBSL at SB-8. However, the lead value is below the Commercial Direct Contact RBSL. TES professional opinion is that the lead value is indicative of background levels of lead found in urban settings and does not pose a threat at the commercial subject property.

19 Section 6 Leaking Underground Storage Tank (LUST) Compliance According to MDEQ records there are no present or historic LUST incidents in connection with this site. Section 7 Conclusions and Recommendations A Phase 2 subsurface investigation was initiated by TES on April 1, 213. The subsurface investigation consisted of the advancement of nine soil borings (SB-1 through SB-9), the installation of two temporary monitoring wells at SB-4 and SB-8, and the collection of groundwater from tank monitoring well TM-1 for the collection of soil and ground water samples for laboratory analysis. The Phase 2 ESA activities were performed to assess the RECs identified in the Phase 1 ESA completed for the site in April 213. Conclusions Results of the Phase 2 ESA indicate no soil impact above the Tier 1 RBSLs at the subject site with the exception of lead at SB-8. However, the lead value at SB-8 is below the Commercial Direct Contact RBSL. TES professional opinion is that the lead value is indicative of background levels of lead found in urban settings and does not pose a threat at the commercial subject property. Results of the Phase 2 ESA indicate that no groundwater contamination is present above the Tier 1 RBSLs with the exception of lead at temporary monitoring points SB-4 and SB-8. However, due to sampling methods, residual sediment in the sampled water may contribute to higher levels of lead than are indicative of normal levels of lead in the groundwater. In addition, the groundwater sample collected from the existing tank monitoring wells did not contain detectable levels of lead. The subject property is located in an urban setting and relies on the City of Detroit for potable water. Therefore, this exceedance does not pose a threat to the subject property. Recommendations TES recommends no further action at this time. This report has been reviewed for its completeness and accuracy.
