Palmer Street in Franklin, North Carolina, and is a former convenience store and gasoline service station. The property is currently not being utilized. Based on a review of the project summary provided by Ms. Sharon Ghiold with the North Carolina Department of Environment and Natural Resources (NCDENR) Underground Storage Tank (UST) Section via electronic mail to our Mr. Al Quarles on June 23, 2011, and previous activities on the site, it is our understanding that: On December 12, 1986, NCDENR staff investigated the site and found gasoline seeping into a culvert across Maple Street from the Palmer Street Texaco. Tank tightness tests were performed. None of the three onsite USTs tested tight. On March 7, 1987 the three USTs were replaced with three new steel tanks. On April 28, 1987 a monitor well was installed onsite and petroleum compounds exceeding the North Carolina Groundwater Quality Standards (2L Standards) were detected. On April 12, 1990, NCDENR staff investigated the site after receiving a report of gasoline entering a culvert ditch. Excavation of the UST product lines confirmed a release from a loose fitting near a dispenser. Five monitor wells (MW-1, MW-2, MW-3, MW-4, and MW-5 were installed onsite. The monitor wells were sampled in July 1990 and March 1991. The laboratory analytical results were provided by Ms. Ghiold and are summarized on the attached Table 1. Petroleum compounds were detected above the 2L Standards in all of the onsite wells, with concentrations in monitor wells MW-1, MW-2, and MW-3 exceeding the Gross Contamination Levels. On April 29, 2008, Hart and Hickman (H&H) sampled the onsite monitor wells. MW-1 was gone due to new construction, and MW-5 was filled with mud and could not be sampled. Contaminant concentrations detected in monitor wells MW-2, MW-3, and MW-4 had decreased significantly since the March 1991 sampling event. However, exceedances of the 2L Standards were detected in each of the three onsite monitor wells with the greatest concentrations detected in monitor well MW-3. On September 25, 2008 the site was inspected by NCDENR and was reported as being abandoned. Conversation with the property owner revealed that the USTs had failed their Cathodic Protection test in June 2007. Groundwater flow across the site has been determined to be toward the northeast. Previous assessment activities do not identify water supply wells within 1,000 feet of the site. The most recent assessment activities conducted by S&ME identified one water supply well approximately 900 feet southwest of the subject site. Crawford Branch (a class C stream) in the Little Tennessee River Basin is located approximately 200 ft north of the site across West Palmer Street. S&ME collected groundwater samples from monitoring wells MW-2, MW-3, and MW-4 on July 26, 2011. The concentrations of several petroleum contaminants in monitor well MW-3 exceeded the 2L Standards. Contaminant concentrations have generally decreased compared to previous sampling events. Groundwater Monitoring Report - Incident No.5550 S&ME Project No. 1354-11-130B Palmer Street Texaco, Franklin, Macon County, NC October 29, 2012 3 In January 2012, NEO Corporation (NEO) removed the three onsite USTs, dispensers, and associated piping. S&ME personnel were onsite to observe some of the closure activities. NEO excavated and disposed of 34.04 tons of petroleum impacted soil located between the northern pump island and monitoring well MW-3. No confirmation soil samples were collected from the excavation extents. Total petroleum hydrocarbon (TPH) gasoline range organics (GRO) concentrations exceeding the NCDENR action level of 10 mg/kg were detected in five of the UST system closure samples with the greatest concentrations being detected in soil samples Pump 4 (294 mg/kg) and Pump 2 (707 mg/kg). The NEO UST closure sampling results are summarized on the attached Table 2. The site location and vicinity are shown in Figure 1 and Figure 2.The site and pertinent features are shown on Figure 3. The scope of services performed for this report were performed in general accordance with S&ME’s Proposal Number 1354-25460-12 dated June 20, 2012, and as authorized by NCDENR’s Task Authorization No. 03 dated June 21, 2012 within NCDENR’s Contract No. 16-1713-4C for the Western Region. 3.0 RECEPTOR INFORMATION S&ME, Inc., (S&ME) performed a receptor study to identify the potential receptors located within 1,500 feet of the subject site.Figure 4 shows the locations of potential receptors located within approximately 1,500 feet and properties within 500 feet of the source area on the subject property. 3.1 Water Supply Wells S&ME identified one water supply well within 1,000 feet of the source area during the receptor survey reconnaissance performed on August 15, 2012 (Figure 4, Map ID #6). The property serviced by the well is located approximately 900 feet southwest of the source area on the subject property. The letters requesting water supply well information were mailed to the owners of 22 properties located within 500 feet of the subject site. To date, responses for 16 of the properties have been received. None of the respondents indicated that a water supply well was located on their property. If information is received by S&ME that requires an update to the receptor survey, S&ME will submit an addendum to this report. A copy of the Request for Water Supply Well Information Letter and the responses to the letter received by S&ME are included in Appendix II.Surrounding property owner information is included in Table 3. 3.2 Public Water Supplies According to the Town of Franklin Water and Sewer Department (TFWSD), potable water is available to properties within 1,000 feet of the site provided by the Town of Franklin. The Town of Franklin obtains water from a surface water intake located on the Cartoogechaye Creek. S&ME contacted Jay Gibson, TFWSD Director, by telephone on Groundwater Monitoring Report - Incident No.5550 S&ME Project No. 1354-11-130B Palmer Street Texaco, Franklin, Macon County, NC October 29, 2012 4 October 25, 2012 who indicated that TCWSD water lines were present throughout the area within 1,000 feet of the subject property. S&ME personnel also observed fire hydrants along West Palmer Street and Maple Street, and within 1,000 feet of the subject property. 3.3 Surface Water According to the 1987 Franklin, NC USGS Quadrangle Map, and S&ME’s site reconnaissance, Crawford Branch (Class C stream) is located approximately 200 feet north of the source area on the subject property (Figure 4). The Little Tennessee River is located approximately one mile east of the source area (Figure 2). 3.4 Wellhead Protection Areas Based on a review of the NCDENR Public Water Supply Section webpage (http://swap.deh.enr.state.nc.us/swap_app/viewer.htm), the subject site is not designated as a Wellhead Protection Area. 3.5 Subsurface Structures Buried municipal water and sewer lines are located on the subject property. A basement is not associated with the building located on the subject site. 3.6 Property Owners and Occupants The names and addresses of the property owners and occupants within 500 feet of the source area are summarized in Table 3. These properties are identified numerically on the receptor survey map which is included as Figure 4. The nearest residence is located approximately 500 feet south of the source area (Property #8,Figure 4). According to the Town of Franklin Zoning Map, the site is zoned NMU – Neighborhood Mixed Use. Surrounding properties are zoned NMU, C1 (Central Commercial), and R1 (Residential). Surrounding property uses include commercial and residential properties. 3.7 Risk Classification Based on the information from the receptor survey, the site meets NCDENR’s criteria for a classification as a High Risk site. One drinking water supply wells was identified 1,000 feet of the source area on the subject property. None of the groundwater contaminants identified exceed the gross contamination levels and no free product was observed at the source area. Contaminants were detected in the groundwater at concentrations above the 2L Standards but not above the Gross Contamination Levels (GCLs). Contaminants were detected in the soil at concentrations above the Soil-to-Groundwater Maximum Soil Contaminant Concentrations (MSCCs) but not the Residential or Industrial/Commercial MSCCs. Surface water is located within 200 feet of the release. Naphthalene (140 micrograms per liter or µg/L) in monitor well MW-1A was detected at a concentration exceeding the surface water standard (2B Standard) of 12 µg/L, by greater than a factor of 10. Groundwater Monitoring Report - Incident No.5550 S&ME Project No. 1354-11-130B Palmer Street Texaco, Franklin, Macon County, NC October 29, 2012 5 4.0 SAMPLING RESULTS 4.1 Soil Sampling Methodology On August 15, 2012, four (4) soil borings were performed using direct push techniques (i.e. Geoprobe). The approximate locations of the borings labeled as SB-1A, SB-2, SB- 3, and SB-4 are shown on Figure 5. Soil boring SB-1A was performed in the approximate location of soil sample Pump 2 collected by NEO during their UST closure activities onsite. Soil boring SB-1A was extended to 5-feet bls where the apparent water table was encountered. Soil sample SB- 1A was collected at approximately 4-feet bls, above the apparent water table. Soil borings SB-2 and SB-3 were performed in the location of the impacted soil excavated by NEO during their UST closure activities. Soil borings SB-2 and SB-3 were extended to 5-feet bls where the apparent water table was encountered. Soil samples SB- 2 and SB-3 were collected from approximately 4-feet bls, above the apparent water table and at the vertical extent of the excavation performed by NEO. Soil boring SB-4 was performed in the approximate location of soil sample Pump 4 collected by NEO during their UST closure activities onsite. Soil boring SB-1A was extended to 5-feet bls where the apparent water table was encountered. Soil sample SB- 1A was collected at approximately 4-feet bls, above the apparent water table. 4.2 Soil Sampling Results In soil sample SB-1A, two carbon fractions [C5-C8 aliphatics (533 mg/kg) and C9-C22 aromatics (314 mg/kg)], were detected at concentrations exceeding their respective Soil- to-Groundwater (STG) Maximum Soil Contaminant Concentrations (MSCCs) of 72 mg/kg and 34 mg/kg. Six (6) additional contaminants were detected in soil sample SB- 1A at concentrations less than the MSCCs. In soil sample SB-2, benzene (1.0 mg/kg), n-butylbenzene (28 mg/kg), sec-butylbenzene (7.2 mg/kg), ethylbenzene (130 mg/kg), p-isopropyltoluene (3.7 mg/kg), naphthalene (64 mg/kg), n-propylbenzene (77 mg/kg), toluene (23 mg/kg), 1,2,4-trimethylbenzene (410 mg/kg), 1,3,5-trimethylbenze (150 mg/kg), and xylenes (490 mg/kg) were detected at concentrations exceeding their STG MSCCs of 0.0056 mg/kg, 4.3 mg/kg, 3.3 mg/kg, 4.9 mg/kg, 0.12 mg/kg, 0.16 mg/kg, 1.7 mg/kg, 4.3 mg/kg, 8.5 mg/kg, 8.3 mg/kg, and 4.6 mg/kg, respectively. In soil sample SB-3, benzene was detected at a concentration of 0.110 mg/kg which exceeds the STG MSCC for benzene of 0.0056 mg/kg. Eleven (11) additional compounds were detected in soil sample SB-3 at concentrations less than the MSCCs. In soil sample SB-4, benzene (0.14 mg/kg), p-isopropyltoluene (0.29 mg/kg), naphthalene (2.6 mg/kg), n-propylbenzene (3.3 mg/kg), and two carbon fractions [C5-C8 aliphatics (132 mg/kg) and C9-C22 aromatics (45 mg/kg)] were detected at concentrations exceeding their STG MSCCs of 0.0056 mg/kg, 0.12 mg/kg, 0.16 mg/kg, Groundwater Monitoring Report - Incident No.5550 S&ME Project No. 1354-11-130B Palmer Street Texaco, Franklin, Macon County, NC October 29, 2012 6 1.7 mg/kg, 72 mg/kg, and 34 mg/kg, respectively. Twelve (12) additional contaminants were detected in soil sample SB-4 at concentrations less than their MSCCs. A copy of the laboratory analytical report is included in Appendix III. 4.3 Monitoring Well Installation Due to the presence of shallow groundwater on the site, prior to installation of groundwater monitoring well MW-1A, S&ME completed and submitted an Application for a Permit to Construct a Well Requiring a Variance to the Title 15 A NCAC 2C .0100 Well Construction Standards to the NCDENR Division of Water Quality (DWQ) dated July 5, 2012. On July 18, 2012, S&ME submitted an Application for Permit to Construct a Monitoring or Recovery Well System to the NCDENR DWQ. On July 25, 2012 the NCDENR DWQ issued Well Variance Construction Permit WV0100052 and Well Construction Permit WM0100303 for construction of monitoring well MW-1A at the Palmer Street Texaco. Copies of the monitoring well construction application, monitoring well construction variance application, and well construction and variance approval letters are included in Appendix IV. On August 15, 2012, S&ME personnel directed the drill crew to advance soil boring SB- 1A into the groundwater table using 4 1/4” hollow stem augers. The soil boring was converted into a groundwater monitoring well (MW-1A) by installing a 10-foot long section of two-inch diameter polyvinyl chloride (PVC) slotted (0.010-inch) screen and sufficient riser pipe to bring the well to ground surface. The well was completed by placing #2 type filter sand in the boring annulus to approximately one foot above the screen section (sand pack). Approximately 0.5 feet of hydrated bentonite was tremied above the sand pack, and neat cement grout was then tremied from the top of the bentonite to approximately two inches bls. The well extended to the ground surface where it was encased with a flush mount protective steel casing with bolted manhole cover. A four-inch thick concrete pad was used to finish the surface of the well. Monitoring well MW-1A was installed to a depth of approximately 12 ft-bls, based on the apparent depth to groundwater of 5 ft-bls at the time of drilling. The monitoring well construction detail is summarized in Table 4. The location of the monitoring well is presented on Figure 3. The monitoring well was developed by evacuating groundwater from the well using a submersible electronic pump until the groundwater became relatively free of visible particulates. The soil boring log and monitoring well construction record are included in Appendix V. 4.4 Monitoring Well Sampling On August 16, 2012, S&ME was on-site to gauge depth-to-water and collect groundwater samples from monitor wells MW-1A, MW-2, MW-3, and MW-4. The depth-to-water gauged onsite was approximately 4 feet below land surface (bls) in each of the monitor wells. After measuring the depth-to-water, S&ME personnel purged each of the monitor wells with a dedicated disposable polyethylene bailer by evacuating approximately three well volumes from each of the wells. Well sampling forms and site photographs are included in Appendix I. Groundwater Monitoring Report - Incident No.5550 S&ME Project No. 1354-11-130B Palmer Street Texaco, Franklin, Macon County, NC October 29, 2012 7 After completing the well purging and allowing groundwater to recover in the monitor wells, S&ME personnel collected a groundwater sample from each of the wells. The groundwater samples were placed in laboratory-supplied containers, stored in a cooler with ice, and shipped under chain-of-custodyprocedures to ShealyEnvironmental Services, Inc., a North Carolina certified laboratoryfor laboratory analysis. The groundwater samples were analyzed for volatile organic compounds (VOCs) byEPA Method 6200B. The groundwater sample collected from monitor well MW-1A was additionallyanalyzed for lead byEPA Method 6010 and Volatile Petroleum Hydrocarbons (VPH) by MADEP. 4.5 Monitoring Well Sampling Results Monitor well MW-1A contained benzene (47 µg/L), chloromethane (3.3 µg/L), naphthalene (140 µg/L), n-propylbenzene (130 µg/L), and three carbon fractions [C5-C8 aliphatics (1,710 µg/L), C9-C18 aliphatics (1,780 µg/L), and C9-C22 aromatics (1,080 µg/L)] at concentrations exceeding their 2L Standards of 1 µg/L, 3 µg/L, 6 µg/L, 70 µg/L, 400 µg/L, 700 µg/L, and 200 µg/L, respectively. The concentration of naphthalene (140 µg/L) also exceeding the surface water standard of 12 µg/L by a factor of 11.7 (more than ten times). Monitor well MW-2 contained benzene (54 µg/L) and naphthalene (31 µg/L) at concentrations exceeding their 2L Standards of 1 µg/L and 6 µg/L, respectively. Thirteen (13) additional contaminants were detected at concentrations that are less than their respective 2L Standards. Monitor well MW-3 contained benzene (240 µg/L), methyl tert-butyl ether or MTBE (250 µg/L), and naphthalene (17 µg/L) at concentrations exceeding their respective 2L Standards of 1 µg/L, 20 µg/L, and 6 µg/L. Thirteen (13) additional contaminants were detected at concentrations that are less than their respective 2L Standards. Monitor well MW-4 contained several petroleum contaminants at concentrations that are less than their respective 2L Standards. No contaminants were detected at concentrations above the Gross Contamination Levels. Contaminant concentrations are generally decreasing with time in each of the sampled monitor wells. A summary of current and historic groundwater analytical results and a comparison to NCDENR’s regulatory standards is included on Table 1.A copy of the laboratory analytical results and chain-of-custody form is included in Appendix III. The contaminants exceeding the 2L Standards are shown on Figure 6. 4.6 Groundwater Flow S&ME used a level and tripod to measure the relative elevations of the monitoring well casings based on an assumed datum of 100.00 feet (top of well casing at monitor well MW-1A). S&ME personnel used an electronic water level indicator to measure the depth-to- groundwater from the top of well casing for groundwater monitoring wells MW-1A, MW-2, MW-3, and MW-4. Depth to water measurements ranged from 3.90 (MW-4) to 4.43 (MW-1A) feet below top-of-casing. The groundwater level measurements from the Groundwater Monitoring Report - Incident No.5550 S&ME Project No. 1354-11-130B Palmer Street Texaco, Franklin, Macon County, NC October 29, 2012 8 August 16, 2012 sampling event are summarized in Table 4. The water level measurements collected on August 16, 2012 were used to prepare a groundwater elevation map (Figure 7). Based on the groundwater elevations, the groundwater flow direction onsite is generally to the north. 4.7 Enhanced Bioremediation Following gauging the depth to groundwater and collection of groundwater samples from monitoring wells MW-1A and MW-3, S&ME installed new 1.25-in diameter by 48-inch long well booms (Universal Remediation Inc., Petroleum Remediation Product) in these monitoring wells. The purpose of the well booms is to enhance the biodegradation (e.g. natural attenuation) of petroleum constituents in the vicinity of the monitoring wells. 5.0 CONCLUSIONS AND RECOMMENDATIONS A limited soil assessment, receptor survey, and groundwater monitoring event were conducted at the Palmer Street Texaco located at 196 W. Palmer Street in Franklin, North Carolina to assess potential petroleum impact to the soil and groundwater from petroleum USTs. The findings at the site are as follows: S&ME collected groundwater samples from monitoring wells MW-2, MW-3, and MW-4 on July 26, 2011. The concentrations of several petroleum contaminants in monitor wells MW-1A, MW-2, and MW-3 exceeded the 2L Standards. Contaminant concentrations have generally decreased compared to previous sampling events. No contaminant concentrations exceeded the Gross Contaminant Levels. The naphthalene concentration in monitor well MW-1A exceeded the surface water quality standard by more than 10 times. In January 2012, NEO Corporation (NEO) removed the three onsite USTs, dispensers, and associated piping. NEO excavated and disposed of 34.04 tons of petroleum impacted soil located between the northern pump island and monitoring well MW-3. On August 15, 2012, S&ME collected soil samples from four soil borings. Contaminant concentrations exceeding the STG MSCCs but less than the residential and industrial/commercial MSCCs were detected in each of these soil samples. An unnamed tributary to the Little Tennessee River is located approximately 200 feet east of the source area on the property. Naphthalene was detected in the groundwater sample collected from monitor well MW-1A at a concentration greater than 10 times the surface water quality standards for Class C streams. Groundwater flow across the site is generally to the north. The depth to groundwater ranged from 3.90 to 4.43 feet below the flush-mount top of well casings. Groundwater Monitoring Report - Incident No.5550 S&ME Project No. 1354-11-130B Palmer Street Texaco, Franklin, Macon County, NC October 29, 2012 9 One drinking water supply well is located approximately 900 feet southwest of the site. Based on the results of this assessment, the site meets the criteria to be ranked as a High Risk site (due to the presence of the one water supply well located ~900 feet southwest of the site). Due to the exceedance of the surface water quality standard by more than ten times, the site also meets the criteria to be ranked as an Intermediate Risk site. Based on the above information, S&ME recommends the following: Pursue a municipal water connection to the property with the active water supply well at 145 West Dogwood Drive. The goal of this task would be to lower the risk classification of the incident from High to Intermediate or Low. Perform aquifer testing at the site (using slug testing of one of the monitor wells) and solute transport modeling to evaluate the potential for impact to the stream located within 200 feet of the site. The goal of this task would be to reduce the risk classification to Low, if the municipal water connection to the above referenced residence if conducted.

Any exceptions to the NELAC standards, the QAMP, SOPs or policies are qualified on the results page or discussed below. If you have any questions regarding this report please contact the Shealy Project Manager listed on the cover page. GC/MS VOC Due to large detections of target compounds, sample -001 was analyzed at a 500X and 2000X dilution causing surrogates to recover outside of method criteria. No corrective action was required as it is known that dilutions of 5X and greater may impact surrogate recoveries. The LCS associated with batch 92388 recovered two compounds marginally outside of method criteria. No corrective action was required as all associated samples were non-detect for these compounds.
