Elm Street Greensboro, North Carolina 27401 (336) 271-3114 Attention: Mr. George House, Attorney-At-law Reference: Phase II Environmental Site Assessment 109–111 West Lewis Street 109 and 111 West Lewis Street Greensboro, Guilford County, North Carolina EA Project No. 14-9927.2 Dear Mr. House: EnviroAssessments (EA) has completed a Phase II Environmental Site Assessment (ESA) of the 109-111 West Lewis Street property (the “Site”), located in Greensboro, Guilford County, North Carolina. A Site Location Map is attached as Figure 1. EA conducted a Phase I Environmental Site Assessment of the Site and a report was submitted to High Point Bank on July 17, 2014 under separate cover. The purpose of the Phase II ESA was to evaluate the Site with respect to potential contamination issues associated with the on- site historic painting operations and auto repair operations and to evaluate the Site for the presence of chlorinated solvents in groundwater which have been identified at the off-site western adjacent property (117 B1 West Lewis Street) and the off-site northern Model Linen-B site. 1.0 SITE HISTORY The Site consists of one approximately 0.24 acre rectangular-shaped parcel of land identified as Parcel Identification Number 7864631801 according to the Guilford County Tax Assessor’s Office. The Site is improved with one approximately 9,269 square foot vacant commercial building which was constructed in 1910. The Site building is currently unoccupied and was formerly occupied by various tenants including Farmers Horse and Mule Company, Carolina Service Corporation Auto Repairs, and Kindley’s Warehouse Storage. The office/warehouse facility was most recently occupied by Kindley’s Office Supply, 109 West Lewis Street and Rhyne Warehouse, 111 West Lewis Street. To summarize the Site history, the Site has been improved with the present building since around 1910. Sanborn maps and/or city directories indicate the Site has been improved since at least 1885. The Site formerly existed as a wagon/carriage company from at least 1885 through 1913; as an auto garage and/or auto Phase II Environmental Site Assessment 2 109–111 West Lewis Street 109 and 111 West Lewis Street Greensboro, Guilford County, North Carolina EA Project No. 14-9927.2 September 8, 2014 repair shop and Pepsi Cola Bottling Company in 1919 through at least 1925; as a furniture warehouse from at least 1950 through 1971; also as an auto repair shop from 1962 through 1965; and as a warehouse and/or office supply company from 1969 through 1989. The building is presently vacant. The ESA revealed no evidence of recognized environmental conditions in connection with the Site, except for the following:  The Site contained operations involving painting from at least 1885 through at least 1919 and auto repair shops in 1919 and from at least 1962 through 1965. Historically, auto repair shops have been known to utilize quantities of petroleum products and solvents, and painting operations have used petroleum-based paints and solvents. These activities typically generate wastes associated with the same substances, the disposal and management of which have not been closely regulated in the past. Based on the length of time the Site historically operated with one or more of these uses (intermittently from at least 1885 through the 1960s), a potential exists that undocumented releases of petroleum products and/or solvents have caused an impact to the Site’s soil and/or groundwater quality.  West Lewis Street Property, located adjacent to the west and topographically cross-gradient of the Site at 117 West Lewis Street, is listed as a Brownfields Management System/Brownfield Sites, Pending Eligibility property. EA completed a prior Phase I Environmental Site Assessment; West Lewis Street Property prepared by EnviroAssessments and dated June 12, 2013 on this property. According to the report, historical resources indicated the property operated as Greensboro Laundry & Cleaners with suspected on-site “dry cleaning” operations from as early as 1950 through 1971. Additionally, the report identified potential off-site sources of chlorinated solvent contaminants in the area. EA completed a subsequent Phase II assessment of the adjacent property, dated August 8, 2013 which identified Tetrachloroethene (PCE) in soil and groundwater at this property, within 30 feet of the Site’s western property boundary. The lateral extent of the contamination has not been defined, including in the direction of the 109-111 West Lewis Street subject Site, and the source(s) of the contamination have not been definitively identified. Therefore, a significant potential exists that similar contamination may also be present in groundwater at the 109-111 West Lewis Street Site.  The property formerly known as Model Linen-B at 120 West Lewis Street, along the north side of West Lewis Street, approximately 40 feet north of the Site property, is listed on the state’s (North Carolina Department of Environment and Natural Resources or NCDENR) Incident Management Database (IMD) and Leaking Underground Storage Tanks (LUST) database with two open incident case numbers: Inc. No. 16349 and Inc. No. 86606. The site has contaminants identified in the groundwater which exceed the NCDENR NCAC 2L Ground Water Quality Standards (NCAC 2L Standards). Some of the contaminants which exceed the NCAC 2L Standards include Benzene, Vinyl Chloride, Trichloroethene, and Tetrachloroethene. A Brownfields plat indicates MW-3 is one of the monitoring wells with concentrations of Benzene and Tetrachloroethene which exceed the NCAC 2L Standards. MW-3 is located approximately 40 feet north of the 109-111 West Lewis Street Site property. Available information does not specify groundwater flow direction and does not indicate if the contamination has migrated off-site to the south toward the Site. Considering the proximity of the contamination at the Model Linen site to the Site property (within 40 feet) and the Phase II Environmental Site Assessment 3 109–111 West Lewis Street 109 and 111 West Lewis Street Greensboro, Guilford County, North Carolina EA Project No. 14-9927.2 September 8, 2014 absence of data detailing contaminant distribution patterns or groundwater flow direction, the Model Linen site is a potential off-site source of contaminants to the 109-111 West Lewis Street subject Site.  We note that the recently revised ASTM E-1527-13 Phase I ESA guidance process requires that Phase I ESAs now consider the potential for vapor encroachment onto a Site property from contamination associated with on-site and nearby off-site sources. The possible presence of volatile hydrocarbons from the on-site and off-site concerns noted above are potential sources of vapor encroachment for the Site property and may pose a potential for vapor intrusion into the Site building which could be considered to be a potential health concern in some situations. In addition, the following BERs (Business Environmental Risks) were identified:  EA personnel noted evidence of water/moisture intrusions and substantial water damaged ceiling finishes on the wood framing and roof supports throughout the Site building. The moisture issues appear to be the result of roof leaks and/or faulty water piping. A potential exists that substantial water/moisture intrusion has proliferated, damaging the building’s interior finishes and potentially its structural materials. No areas of suspect mold growth were observed during EAs physical inspection of the Site building. EA personnel did not observe any areas which were not readily accessible such as attics, crawl spaces, and ventilation systems. Significant damage of the building and the presence of mold are conditions which normally detract from the value and “marketability” of a property. In order to confirm the presence of absence of mold or excessive moisture conditions, particularly in areas that are not readily accessible or visible (i.e.; attics, ventilation systems, etc.), a formal mold and moisture inspection would be necessary.  Considering the age of the Site building (constructed in 1910) a potential exists that asbestos- containing materials (ACMs) could be present in some of the building’s construction materials. EA personnel observed no obvious evidence of damaged suspect ACMs. However, in order to confirm the presence or absence of ACMs in any structure, a formal ACM survey would be required.  Based on the age of the Site building (constructed in 1910) a potential exists that lead based paint (LBP) could be present on some of the building’s painted surfaces. EA personnel observed no significant amounts of damaged paint at the Site. However, in order to confirm the presence or absence of lead-based paint in any structure, a formal lead-based paint survey would be required. The Client (Brooks Pierce) authorized EA to complete a Phase II ESA to evaluate the Site in order to determine potential on-site impacts from the concerns noted above, the details of which are provided in the following sections of this report. Phase II Environmental Site Assessment 4 109–111 West Lewis Street 109 and 111 West Lewis Street Greensboro, Guilford County, North Carolina EA Project No. 14-9927.2 September 8, 2014 2.0 FIELD ACTIVITIES 2.1 Subsurface Utility Locating EA personnel contacted the North Carolina One Call Center and requested that the local utility services conduct an Electromagnetic (EM) Survey in the area of concern at the Site to determine the orientation and location of underground utility lines for optimal sampling locations. At the time of the assessment, underground utility lines appeared to be marked up to the Site boundaries. However, public utilities are not authorized to locate underground lines on private property. On August 22, 2014, EA and its subcontractor, Sweetwater Utility Exploration (Sweetwater), conducted an on-site ground-penetrating radar (GPR) survey and EM survey at the Site to determine the orientation and location of on-site subsurface utilities (including building interior) in order to determine optimal sampling locations. All items located were marked directly on the surface using paint. 2.2 Soil Assessment On August 22, 2014, EA and its subcontractor utilized a Geoprobe® sampling device to advance soil sample points in six (6) locations (S-1 through S-6) of the Site, as depicted on the attached Figure 2. A total of six (6) on-site soil samples (S-1-2, S-2-2, S-3-2, S-4-2, S-5-2 and S-6-2) were collected from the six (6) soil boring locations. EA personnel screened the soil columns for Volatile Organic Compounds (VOCs) from each boring at two-foot intervals using a Photo Ionization Detector (PID), and visual and olfactory indicators. Phase II Site Photos are included as Appendix 1. Boring logs are included in Appendix 2 which detail soil descriptions, sampling depths and field screening results. Soil boring S-1 was advanced to a depth of 18 feet below grade (BG) near the western interior wall of the 109 West Lewis Street building. Soils encountered in the boring consisted of concrete at depths of 0-2 inches underlain by tan/red stiff clay and dark brown/black silt at depths of 2 inches to 4 feet BG, tan/red clayey silt at depths of 4-16 feet BG and brown/gray micaceous clayey silt at depths of 16-18 feet BG. Soils were observed to be moist at depths of 8-16 feet BG and saturated at depths of 16-18 feet BG. Petroleum odors were noted in the soil at depths of 8-18 feet BG. Field screening of the soils did not indicate detectable VOC concentrations in the soils at depths of 2-6 feet BG; however, detectable VOC concentrations ranged from 0.5 parts per million (ppm) at a depth of 8 feet BG to 162 ppm at a depth of 18 feet BG. One (1) soil sample (S- 1-2) was collected at a depth of two (2) feet BG from soil boring S-1. Soil boring S-2 was advanced to a depth of 20 feet below grade (BG) near the western interior wall of the 109 West Lewis Street building and to the north of soil boring S-1. Soils encountered in the boring consisted of concrete at depths of 0-2 inches underlain by tan/red clayey silt at depths of 2 inches to 12 feet BG and brown/gray micaceous clayey silt at depths of 12-20 feet BG. Soils were observed to be moist at depths of 12- 14 feet BG and saturated at depths of 14-20 feet BG. Petroleum odors were noted in the soil at depths of 12- 20 feet BG. Field screening of the soils did not indicate detectable VOC concentrations in the soils at depths of 2-6 feet BG. One (1) soil sample (S-2-2) was collected at a depth of two (2) feet BG from soil boring S-2. Phase II Environmental Site Assessment 5 109–111 West Lewis Street 109 and 111 West Lewis Street Greensboro, Guilford County, North Carolina EA Project No. 14-9927.2 September 8, 2014 Soil boring S-3 was advanced to probe refusal, which was encountered at a depth of 18 feet below grade (BG), near the northwestern exterior portion of the 109 West Lewis Street building. Soils encountered in the boring consisted of concrete at depths of 0-2 inches underlain by tan stiff clay at depths of 2 inches to 4 feet BG, tan/red clayey silt at depths of 4-12 feet BG, tan/gray clayey silt at depths of 12-16 feet BG and tan sandy silt at depths of 16-18 feet BG. Soils were observed to be moist at depths of 16-18 feet BG. Petroleum odors were noted in the soil at depths of 12-18 feet BG. Field screening did not indicate detectable VOC concentrations at depths of 2-6 feet BG. One (1) soil sample (S-3-2) was collected at a depth of two (2) feet BG from soil boring S-3. Soil boring S-4 was advanced to a depth of 8 feet below grade (BG) near the southern exterior of the 109 West Lewis Street building. Soils encountered in the boring consisted of tan stiff clay at depths of 0-4 feet BG underlain by tan clayey silt at depths of 4-8 feet BG. The soils were observed to be dry and no solvent or petroleum odors were noted in soil boring S-4. Field screening did not indicate detectable VOC concentrations in the soils at depths of 2-8 feet BG. One (1) soil sample (S-4-2) was collected at a depth of two (2) feet BG from soil boring S-4. Soil boring S-5 was advanced to a depth of 8 feet below grade (BG) near the southern exterior of the 111 West Lewis Street building and to the west of soil boring S-4. Soils encountered in the boring consisted of dark brown stiff clay at depths of 0-2 feet BG underlain by tan/red clayey silt at depths of 2-8 feet BG. The soils were observed to be dry and no solvent or petroleum odors were noted in soil boring S-5. Field screening did not indicate detectable VOC concentrations in the soils at depths of 2-8 feet BG. One (1) soil sample (S-5-2) was collected at a depth of two (2) feet BG from soil boring S-5. Soil boring S-6 was advanced to a depth of 20 feet below grade (BG), near the southwestern exterior portion of the 111 West Lewis Street building and to the west of soil boring S-5. Soils encountered in the boring consisted of dark brown clayey silt at depths of 0-2 feet BG underlain by brown clayey silt at depths of 2-12 feet BG and gray/tan silty sand at depths of 12-20 feet BG. Soils were observed to be moist at depths of 8-16 feet BG and saturated at depths of 16-20 feet BG. Solvent odors were noted in the soils at depths of 12-20 feet BG. Field screening did not indicate detectable VOC concentrations at depths of 2-6 feet BG. One (1) soil sample (S-6-2) was collected at a depth of two (2) feet BG from soil boring S-6. The soil samples were placed into appropriate sample containers and labeled with the Site name, time and date of collection, and analysis to be performed. The filled sample containers were placed in a cooler containing ice and transported to Pace Analytical Services, Inc. in Huntersville, North Carolina (a North Carolina-certified laboratory). A chain-of-custody form was maintained with the samples. All soil samples were submitted and analyzed for volatile organic compounds (VOCs) by EPA Method 8260 and semi-volatile Polynuclear Aromatic Hydrocarbons (PAHs) by EPA Method 8270. A copy of the laboratory analytical report is attached as Appendix 3. The laboratory results are discussed in Section 3.0 of this report. Phase II Environmental Site Assessment 6 109–111 West Lewis Street 109 and 111 West Lewis Street Greensboro, Guilford County, North Carolina EA Project No. 14-9927.2 September 8, 2014 2.3 Groundwater Assessment On August 22, 2013, EA and its subcontractor utilized the Geoprobe sampling device to install a total of four (4) temporary groundwater piezometer wells at the Site (TMW-1 through TMW-4) in the locations of the Site depicted on the attached Figure 2. All groundwater piezometer wells were constructed of 1-inch diameter PVC screen and casing and completed approximately 1-2 feet above grade. Detailed well construction information is included in Table 4. Piezometer well TMW-1 was installed to the termination depth (18 feet BG) in soil boring S-1 and the well was constructed with 10 feet of screen (8-18 feet BG). Piezometer well TMW-2 was installed to the termination depth of soil boring S-2 (20 feet BG) and the well was constructed with 10 feet of screen (10-20 feet BG). Piezometer well TMW-3 was installed to the termination depth of soil boring S-3 (18 feet BG) and the well was constructed with 10 feet of screen (8-18 feet BG). Piezometer well TMW-4 was installed to the termination depth of soil boring S-6 (20 feet BG) and the well was constructed with 10 feet of screen (10-20 feet BG). Upon installation, the piezometer wells were developed/purged and allowed to equilibrate for approximately 1-6 hours prior to collecting groundwater samples. Temporary piezometer well boring/well construction logs are included in Appendix 2. On August 22, 2013, EA personnel collected groundwater samples (TMW-1 through TMW-4) from each of the four (4) piezometer wells using clean, dedicated polypropylene tubing and a peristaltic pump. In addition, EA personnel collected one (1) groundwater sample from an existing off-site groundwater monitoring well (MW-3) located to the northwest of the Site at 120 West Lewis Street (currently Lotus Lounge). Prior to collecting the groundwater sample from MW-3, EA personnel purged the monitoring well of approximately 3 well volumes of water. The groundwater samples were placed into appropriate sample containers and labeled with the Site name, time and date of collection, and analysis to be performed. The filled sample containers were placed in a cooler containing ice and transported to PACE Analytical in Huntersville, North Carolina (a North Carolina- certified laboratory). A chain-of-custody form was maintained with the sample. The groundwater samples were submitted and analyzed for VOCs by EPA Method 8260 and PAHs by EPA Method 8270. A copy of the laboratory analytical report is attached as Appendix 3. The laboratory results are discussed in Section 3.0 of this report. On August 25, 2014, EA personnel returned to the Site to gauge groundwater levels in the temporary piezometer wells and off-site existing groundwater monitoring well MW-3. EA gauged the depth to the groundwater table (from the top of well casings) for each of the on-site groundwater piezometer wells. Using a SpectraVision Laser Level, EA personnel surveyed the elevations of the tops of each well casing. Using an assumed benchmark elevation, EA calculated relative well casing elevations. Using the water table depths, EA then calculated the relative water table elevations at each well point. The well casing and water table data are provided on Table 4. All of the piezometer wells appear to be hydraulically connected as part of the same surficial water table aquifer. The relative water table elevations and groundwater-flow direction are presented on Figure 3. Based on the groundwater elevation measurements taken at the Site, the shallow groundwater flow direction is interpreted to be generally to the southeast across the site. Phase II Environmental Site Assessment 7 109–111 West Lewis Street 109 and 111 West Lewis Street Greensboro, Guilford County, North Carolina EA Project No. 14-9927.2 September 8, 2014 2.4 Sub-Slab Assessment On August 22, 2014, EA and its subcontractor utilized a Geoprobe® sampling device to install one (1) temporary sub-slab vapor probe (VP-1) in the location depicted on the attached Figure 2. The boring was advanced to a depth of 4 feet BG to the north of a floor drain located near the center of the 109 West Lewis Street building. A temporary sub-slab vapor probe constructed of a stainless steel mesh sampling point connected to ¼ inch diameter Teflon tubing was inserted into the boring to a depth of 3 feet BG. Sand was placed around the sampling point at depths of 2.5-4 feet BG and bentonite was utilized to seal the boring to the floor surface. Once a proper seal had been established, at least five (5) volumes of air were purged from the tubing and sand pack interval prior to sample collection. One (1) sub-slab vapor sample (VP-1) was collected by attaching the tubing to a dedicated one-liter Summa vacuum canister and a pre-calibrated ten-minute flow controller with vacuum gauge. The Summa canister was then opened and a sub-slab vapor sample was collected at an approximate flow rate of 70 milliliters per minute for approximately 14 minutes, until the vacuum remaining in the canister measured approximately 3 inches inches of Mercury (Hg). The Summa canister was labeled with the Site name, time and date of collection, canister ID, flow control number and analysis to be performed. The filled canister was transported to Pace Analytical in Huntersville, North Carolina (a North Carolina-certified laboratory). A chain-of-custody form was maintained with the sample. The sub-slab vapor sample was submitted and analyzed for VOCs by EPA Method TO-15. A copy of the laboratory analytical report is attached as Appendix 3. A Field Data Sheet containing detailed sub-slab vapor sampling information is attached as Appendix 4. The laboratory results are discussed in Section 5.0 of this report. 3.0 LABORATORY ANALYTICAL RESULTS 3.1 Soil Assessment EA collected a total of six (6) soil samples (S-1-2, S-2-2, S-3-2, S-4-2, S-5-2 and S-6-2) in the locations shown on Figure 2. A copy of the laboratory analytical report is attached as Appendix 3 and a summary of the soil sampling results is presented in Table 1. In Summary, laboratory analysis did not reveal concentrations of target analytes exceeding North Carolina Department of Environment and Natural Resources (NCDENR), Inactive Hazardous Sites Branch (IHSB) Industrial Health-Based Preliminary Soil Remediation Goals (PSRGs) or Protection of Groundwater PSRGs. Laboratory analysis of soil sample S-1-2 revealed an Acetone concentration of 0.230 milligrams per kilogram (mg/kg), which does not exceed the Protection of Groundwater PSRG of 24 mg/kg of the Industrial Health- Based PSRG of 100,000 mg/kg for Acetone. No target analytes were detected above laboratory reporting limits in the remaining soil samples (S-2-2, S-3-2, S-4-2, S-5-2 and S-6-2). Refer to Sections 4.0 and 5.0 for EA’s conclusions and recommendations. Phase II Environmental Site Assessment 8 109–111 West Lewis Street 109 and 111 West Lewis Street Greensboro, Guilford County, North Carolina EA Project No. 14-9927.2 September 8, 2014 3.2 Groundwater Assessment EA collected a total of five (5) groundwater samples (TMW-1, TMW-2, TMW-3, TMW-4 and MW-3) at the locations shown on Figure 2. A copy of the laboratory analytical report is attached as Appendix 3 and a summary of the groundwater sampling results is presented in Table 2. In Summary, four (4) of the five (5) groundwater samples (TMW-1, TMW-2, TMW-4 and MW-3) revealed concentrations of the target analytes exceeding NCAC 2L Groundwater Quality Standards (2L Standards). None of the groundwater samples revealed concentrations of target analytes exceeding Gross Contamination Levels (GCLs). Laboratory analysis of on-site groundwater sample TMW-1 revealed a Benzene concentration of 59.8 micrograms per liter (ug/L), which exceeds the 2L Standard of 1 ug/L for Benzene. Groundwater sample TMW-1 revealed concentrations of Naphthalene (316 ug/L), and 2-Methylnaphthalene (33.0 ug/L) which exceed the 2L Standards of 6 ug/L for Naphthalene and 30 ug/L for 2-Methylnaphthalene. In addition, groundwater sample TMW-1 revealed a 1-Methylnaphthalene concentration of 14.9 ug/L which exceeds the Interim Maximum Allowable Concentration (IMAC) of 1 ug/L for 1-Methylnaphthalene (effective April 1, 2011). No other target analytes were detected in groundwater sample TMW-1 at concentrations exceeding 2L Standards or IMACs. However, several additional target analytes were detected in groundwater sample TMW-1 at concentrations below their respective 2L Standards. Laboratory analysis of on-site groundwater sample TMW-2 revealed a Naphthalene concentration of 99.9 ug/L, which exceeds the 2L Standard of 6 ug/L for Naphthalene. No other target analytes were detected in groundwater sample TMW-2 at concentrations exceeding 2L Standards or IMACs. However, several additional target analytes were detected in groundwater sample TMW-2 at concentrations below their respective 2L Standards. Laboratory analysis of on-site groundwater sample TMW-3 did not reveal any target analyte concentrations exceeding 2L Standards. Groundwater sample TMW-3 revealed a Naphthalene concentration of 4.0 ug/L, which is below the 2L Standard of 6 ug/L for Naphthalene. No other target analytes were detected in groundwater sample TMW-3 at concentrations exceeding laboratory reporting limits. Laboratory analysis of on-site groundwater sample TMW-4 revealed concentrations of Naphthalene (420 ug/L), Ethylbenzene (668 ug/L), Total Xylenes (1,030 ug/L) and 2-Methylnaphthalene (33.7 ug/L), which exceed the 2L Standards of 6 ug/L for Naphthalene, 600 ug/L for Ethylbenzene, 500 ug/L for Total Xylenes and 30 ug/L for 2-Methylnaphthalene. Groundwater sample TMW-4 also revealed a 1-Methylnaphthalene concentration of 16.7 ug/L, which exceeds the IMAC of 1 ug/L for 1-Methylnaphthalene. No other target analytes were detected in groundwater sample TMW-4 at concentrations exceeding 2L Standards or IMACs. However, several additional target analytes were detected in groundwater sample TMW-4 at concentrations below their respective 2L Standards. Laboratory analysis of off-site groundwater sample MW-3 revealed concentrations of Benzene (4.7 ug/L), Naphthalene (53.9 ug/L) and Tetrachloroethene (PCE; 13.1 ug/L), which exceed the 2L Standards of 1 ug/L for Benzene, 6 ug/L for Naphthalene and 0.7 ug/L for PCE. Groundwater sample MW-3 also revealed a 1- Methylnaphthalene concentration of 13.7 ug/L, which exceeds the IMAC of 1 ug/L for 1-Methylnaphthalene. No other target analytes were detected in groundwater sample MW-3 at concentrations exceeding 2L Phase II Environmental Site Assessment 9 109–111 West Lewis Street 109 and 111 West Lewis Street Greensboro, Guilford County, North Carolina EA Project No. 14-9927.2 September 8, 2014 Standards or IMACs. However, several additional target analytes were detected in groundwater sample MW- 3 at concentrations below their respective 2L Standards. Refer to Sections 4.0 and 5.0 for EA’s conclusions and recommendations. 3.3 Sub-Slab Assessment EA collected a total of one (1) sub-slab vapor sample (VP-1) for laboratory analysis, the location of which is depicted on Figure 2. The sub-slab vapor sampling analytical results are presented in Table 3 and Figure 2. A copy of the laboratory analytical report is attached as Appendix 3. A Field Data Sheet containing detailed sub-slab vapor sampling information is attached as Appendix 4. In summary, laboratory analysis of sub-slab vapor sample VP-1 did not reveal concentrations of target analytes exceeding NCDENR, Division of Waste Management (DWM), Non-Residential Sub Slab and Exterior Soil Gas Screening Levels (SGSLs), recently updated for June 2014 and used by the IHSB. Laboratory analysis of sub-slab vapor sample VP-1 revealed detectable concentrations of several target analytes; however, none of the detected concentrations exceed DWM Non-Residential SGSLs. Refer to Sections 4.0 and 5.0 for EA’s conclusions and recommendations. 4.0 CONCLUSIONS 4.1 Soil Assessment EA collected a total of six (6) soil samples (S-1-2, S-2-2, S-3-2, S-4-2, S-5-2 and S-6-2) in the locations shown on Figure 2. In summary, none of the soil samples revealed concentrations of target analytes exceeding IHSB Industrial Health-Based PSRGs or Protection of Groundwater PSRGs. Based on the laboratory analytical results, no significant petroleum or solvent contamination was identified in shallow on-site soils in the areas of the site investigated during this Phase II ESA. However, three (3) of the four (4) on-site groundwater samples (TMW-1, TMW-2 and TMW-4) revealed concentrations of petroleum constituents exceeding 2L Standards. The source area of the identified on-site petroleum-contaminated groundwater plume is currently unknown; however, considering the Site’s former automotive repair activities, a potential exists that an on-site source area is associated with the identified on- site petroleum-contaminated groundwater. 4.2 Groundwater Assessment EA collected a total of five (5) groundwater samples (TMW-1 through TMW-4 and MW-3) in the locations shown on Figure 2. In summary, four (4) of the five (5) groundwater samples (TMW-1, TMW-2, TMW-4 and MW-3) revealed concentrations of target analytes exceeding 2L Standards. Phase II Environmental Site Assessment 10 109–111 West Lewis Street 109 and 111 West Lewis Street Greensboro, Guilford County, North Carolina EA Project No. 14-9927.2 September 8, 2014 Groundwater samples TMW-1, TMW-2 and TMW-4 revealed concentrations of petroleum constituents exceeding 2L Standards in on-site groundwater. Groundwater sample TMW-4, collected near the southwestern exterior corner of the 111 West Lewis Street building, generally revealed the highest concentrations of petroleum constituents in on-site groundwater during this Phase II ESA. None of the six (6) soil samples collected during this Phase II ESA revealed detectable concentrations of petroleum constituents in on-site shallow soil and the source area for the identified petroleum-contaminated groundwater is currently unknown. However, considering the Site’s former painting and automotive repair activities, a potential exists that an on-site source area is associated with the petroleum-contaminated groundwater. Groundwater sample MW-3, collected from an existing groundwater monitoring well located off-site and approximately 40 feet to the northeast of the Site at 120 West Lewis Street (currently Lotus Lounge), revealed concentrations of petroleum and solvent constituents exceeding 2L Standards. The elevated petroleum and solvent constituent concentrations detected in MW-3 appear to be associated with previously identified and documented release incident numbers 16349 and 86606 at the Model Linen-B site formerly located at 120 West Lewis Street. Based on the groundwater elevation measurements taken at the Site and from off-site groundwater monitoring well MW-3, the shallow groundwater flow direction is interpreted to be generally to the southeast and towards the Site. Therefore, the potential exists that the petroleum contamination identified in on-site groundwater may be associated with the previously documented release incidents associated with the Model-Linen B site. However, based on the lack of solvent constituents detected in the on-site groundwater samples (TMW-1, TMW-2, TMW-3 and TMW-4) and considering the highest concentrations of petroleum constituents were detected in the groundwater sample (TMW-4) located the farthest distance from MW-3, it does not appear likely that the on-site petroleum-contaminated groundwater has been significantly impacted as a result of the release incidents associated with the Model Linen-B site. Two of the groundwater samples (TMW-1 and TMW-4) revealed concentrations of petroleum constituents exceeding NCDENR, DWM Non-Residential Vapor Intrusion Groundwater Screening Levels (GWSLs). Groundwater samples TWM-1 and TMW-4 revealed concentrations of Ethylbenzene and Naphthalene which exceed the DWM Vapor Intrusion GWSLs of 152 ug/L for Ethylbenzene and 146 ug/L for Naphthalene. In addition, groundwater sample TWM-4 revealed a Total Xylenes concentration of 1,030 ug/L, which exceeds the DWM GWSL of 414 ug/L for Total Xylenes. DWM GWSLs are detailed in the Groundwater Sampling Analytical Table (Table 2). Refer to section 4.3 for additional information regarding on-site structural vapor intrusion potential at the Site. 4.3 Sub-Slab Vapor Intrusion Assessment EA collected a total of one (1) sub-slab vapor sample (VP-1) for laboratory analysis, the location of which is depicted on Figure 2. The sub-slab vapor sampling analytical results are presented in Table 3 and Figure 2. A copy of the laboratory analytical report is attached as Appendix 3. In Summary, laboratory analysis of sub-slab vapor sample VP-1 did not reveal concentrations of target analytes exceeding NCDENR, DWM, Non-Residential Sub Slab and Exterior Soil Gas and Screening Levels (SGSLs), recently updated for June 2014. Laboratory analysis of soil-slab vapor sample VP-1 revealed detectable concentrations of several target analytes; however, none of the detected concentrations exceed DWM Non-Residential SGSLs. Phase II Environmental Site Assessment 11 109–111 West Lewis Street 109 and 111 West Lewis Street Greensboro, Guilford County, North Carolina EA Project No. 14-9927.2 September 8, 2014 Based on the laboratory analytical results of sub-slab vapor sample VP-1, no evidence of significant adverse impact associated with potential vapor encroachment/migration from the off-site northwestern Model Linen-B release incidents and/or from the western adjacent 117 B West Main Street property was identified at the Site during this Phase II ESA. However, two (2) of the groundwater samples (TMW-1 and TMW-4) collected at the Site revealed concentrations of target analytes exceeding NCDENR, DWM Non-Residential Vapor Intrusion Groundwater Screening Levels (GWSL). Based on the presence of on-site groundwater exceeding DWM GWSLs and the limited sub-slab vapor sampling conducted during this Phase II ESA, the potential exists for structural vapor intrusion potential to have adversely impacted portions of the Site not investigated during this Phase II ESA. Sub-slab sampling results can vary significantly according to seasonal and temporal weather conditions (rain, snow, barometric pressure changes) along with changes to potential migration pathways such as utilities and surficial cover (impervious surfaces such as pavement, buildings, clay fill). 5.0 RECOMMENDATIONS We recommend that this report be forwarded to the Guilford County Department of Public Health (GCDPH) for guidance on whether additional site assessment will be required under State guidelines. The GCDPH will consider the findings with regard to potential on-site and off-site sources and potentially responsible parties. The GCDPH could require additional soil and groundwater assessment at the Site to further evaluate the following: 1. the lateral and vertical extents of potential on-site source areas of petroleum contamination identified in on-site groundwater; 2. more definitive evaluation of potential off-site sources of contamination; 3. potential “worst case” conditions for sub-slab vapors as a function of colder temperatures and various temporal weather conditions. We also recommend that the Client consider determination of eligibility into the Brownfield Program by preparing Brownfields Property Application for the Site and/or inclusion with the adjacent property to the west (117 B1 West Lewis Street).
