B. Executive Summary
Summarize the most pertinent information for the monitoring period presented in this report: 1. Indicate the maximum free product thickness; Evidence of free product was encountered in wells MW-11 and MW-14 while attempting to sample. A petroleum sheen was observed in purge water from wells MW-11 and MW-14 on December 13, 2022. A free product measurement was attempted in the wells with an oil/water interface probe on December 14, 2022. A measurable amount of free product was not detected. 2. Indicate the maximum concentrations of dissolved groundwater contaminants and compare to cleanup goals; The highest concentrations of dissolved-phase petroleum constituents were detected in groundwater samples from wells MW-6, MW-12, and MW-15 which make up the northern core of the plume. A petroleum sheen was observed in purge water from wells MW-11 and MW-14. The maximum concentrations of petroleum constituents were detected in MW-15. Four of the constituents were detected at concentrations above the NC 2L Standards. Benzene was detected at 52.0 µg/l and the NCDEQ 2L Standard is only 1 µg/l. Naphthalene was detected at 863 µg/l above the NCDEQ 2L Standard of 6 µg/l. Eight constituents were detected at concentrations below the NCDEQ 2L Standards.
2
Thirteen total petroleum constituents were detected in MW-6, but only two of these were detected above the NCDEQ 2L Standards; benzene at 34.8 µg/L and n-propylbenzene at 148 µg/L.
3. Describe the current extent of dissolved groundwater contamination (and free product, if present) and
compare to the historical extent; The dissolved-phase plume (constituents at or above the NC 2L Standards) extends from the source area
at well MW-14 northeast to well MW-6. Petroleum constituents were not detected above the NC 2L Standards in downgradient well MW-7, but it is possible that the plume extends to Little Buffalo Creek east of MW-7. The width of the plume above the NC 2L Standards is narrow on the northwest side of NC Highway 88 as petroleum constituents were not detected above the 2L Standards in well MW-13. The plume was shown
as 160 feet wide on the 2009 groundwater analytical map. There has been a significant decrease in plume width. The current plume length is drawn as about 120 feet and the length of the plume in 2009 was shown as about 260 feet. This is a 54% decrease in the plume length.
4. Indicate the maximum contaminant concentrations in soil in the unsaturated zone (from the most recent sampling event) and compare to cleanup goals;
Soil samples were not collected during this reporting period. Accessible soil in the source area with petroleum constituent concentrations above the MSCC’s has been excavated and removed from the site. 5. Briefly describe any remedial action plan currently or previously in use and comment on the effectiveness
of that strategy and/or natural attenuation at reducing the estimated contaminant mass onsite over time (where applicable, based on the most recent Corrective Action Performance Report);
Natural attenuation is currently being used to reduce the contaminant mass at the site. Petroleum constituent concentrations have decreased significantly since the previous monitoring event in 2015. For
example, in MW-6 the total EPA Method 6200B concentrations have decreased from 5,706 µg/L in 2015 to 414 µg/L in 2022. This is an indication that Natural Attenuation is reducing the contaminant mass over time.
6. Indicate if receptors have been impacted or are at imminent risk of impact, and what response (if any) has
been made to address that risk. The onsite water supply well (UWS) and the downgradient water supply well (SW-1) are the closest
potential receptors. Little Buffalo Creek is also a potential receptor. Petroleum constituents have not been detected in water samples from these three potential receptors.

D. Site History and Characterization
Present information relevant to site history and characterization, updating information provided in the CAP and
previous monitoring reports using the following outline: 1. Provide UST owner and operator information. Refer to Table B-2 in Section K.
2. Provide UST information (inclusive of all USTs, currently and historically in place at facility). Refer to Table B-1 in Section K and to site map in Section J.
3. Provide non-UST (AST, spill) information. Refer to Table B-1 in Section K and to site map in Section J. Spills are not known to have occurred at the property.

4. Provide a description of the release, including date discovered, cause and source (including tank identification number and contents), and the relationship of historical UST releases, non-UST releases, and
off-site releases (indicate incident number) to contamination from current release. Enviromark, P.A. performed tank closures at the former Smethport U-SAV on 06/29/00 (UST #1) and 03/16/01 (USTs #2, #3 and #4). Contaminated soil was discovered during the tank closure when the 8,000 gallon (UST #2), 6,000 gallon gasoline (UST#3), and 4,000 gallon (UST #4) were removed on 03/16/01.
The release appears to have originated in the tank pits and around the pump island. The volume of petroleum released from the USTs is unknown. This is the only documented release at the site.
5. Provide a brief description of site characteristics (including land use of site and surrounding area,
topography, vegetation, surface water, wells, buildings, surface cover, soil type, depth to and nature of bedrock, depth to groundwater, direction of groundwater flow, etc.).
The site is currently Ashe Tire Service, a locally owned tire store. The site was used as a service station for many years prior to discontinuing the sale of petroleum products and closing of the USTs in 2001. The site is located on 5-10 ft. of sandy silt fill material. Paddy Mountain is located to the southwest of the site, which has a moderate to steep slope down into the Little Buffalo Creek Valley (Figure 1 in Section J). Little
Buffalo Creek is located approximately 150 feet northeast of the source area (Figure 2 in Section J). Mr. Ellison owns the property between Ashe Tire Service and Little Buffalo Creek. The source area at Ashe Tire
is paved from the building to the road. The surrounding properties are residential and commercial properties. The updated receptor survey identified 40 water supply wells located within 1,500 feet of the source area. The closest water supply well (UWS) is located approximately 110 feet up gradient from the source
area on the Ashe Tire property (Figures 2 and 9 in Section J). There is also a water supply well located approximately 225 feet cross-gradient from the source area on the Roten Insurance Agency property (SW-6)
and a water supply well (SW-1) located about 200 feet down/cross-gradient from the source area at the mobile home north of the source area. The water levels measured in monitoring wells indicate that groundwater
flow is to the northeast toward Little Buffalo Creek. The relative groundwater elevations are shown on Figure 3 in Section J.
6. Provide information on owners and occupants of property within or adjacent to area containing
contamination or the area where contamination is expected to migrate and describe land use. Table B-6 lists information about property owners adjacent to the site. There is a storage unit business
located to the northwest of the site. An insurance agency is located southeast of the site. There is a horticulture nursery on the northeast side of Little Buffalo Creek. The single-family mobile home between the site and
Little Buffalo Creek is owned by Mr. Willard Ellison (Figure 2). There is a single family residential home located southwest of the site. Refer to Table B-6, Property Owners / Occupants and Table B-10, Land Use,
and the land use map (Figure 10).
7. Present information on receptors/potential receptors. A public water supply is not available in this part of Ashe County. The release is outside of the wellhead
protection area for the Town of West Jefferson. The dissolved-phase plume extends from the source area across the Little Buffalo Creek floodplain to the stream channel. The dissolved-phase plume is referred to in
this report as the horizontal extent of petroleum constituents above the NC 2L Groundwater Standards.
The water supply well that supplies water to the Ashe Tire facility is located about 110 feet upgradient of the source area. The water supply well that provides drinking water to the mobile home is about 110 feet
northwest of the edge of the plume. The other water supply wells listed in Table B-5 are upgradient, separated by a groundwater divide or too distant to the source area that they do not appear to be at risk. Little Buffalo Creek is also a potential receptor.
8. Summarize implementation of the remedial plan proposed in the CAP. The remedial plan proposed in the CAP consisted of soil excavation with off-site treatment and natural
attenuation. 162.08 tons of contaminated soil was removed during the soil excavation activities conducted on March 18, 2004. Free product measured during previous monitoring events appears to have been addressed by the two AFVR events and two MMPE events conducted at the site.
5
Natural attenuation is currently being used to reduce the contaminant mass at the site.
9. Describe the progress of remediation at the site, as indicated in monitoring reports, from initial implementation of the remedial plan to the latest monitoring of soil and/or groundwater contamination. The dissolved-phase plume is being addressed through monitored natural attenuation, which is effective at both documenting the changes in concentrations of petroleum constituents and assessing the impact to
potential receptors.
Plate 1. Graph of total 6200B concentrations over time in wells MW-6, MW-12, and MW-15.
The concentration of volatile petroleum constituents (EPA Method 6200B) detected in monitoring well MW-15 was 11,139 µg/L in 2011. This decreased to 8,183 µg/L in 2013 and then increased to 13,467 µg/L in 2015 (Plate 1). This 2022 sampling event saw an 80% decrease to 2,673 µg/L. The concentration of volatile petroleum constituents (EPA Method 6200B) detected in monitoring well MW-6 was 2,725 µg/L in 2011. This increased to 3,827 µg/L in 2013 and increased again to 5,706 µg/L in 2015 (Plate 1). This 2022 sampling event saw a 92% decrease to 414 µg/L. The concentration of volatile petroleum constituents (EPA Method 6200B) detected in monitoring well MW-12 was 10,772 µg/L in 2011. This increased to 15,186 µg/L in 2013 and then decreased to 7,919 µg/L in 2015 (Plate 1). This 2022 sampling event saw a 96% decrease to 319 µg/L. There was a significant decrease in petroleum constituent concentrations in the downgradient wells MW-15, MW-12 and MW-6. To evaluate whether the changes in petroleum constituent concentrations were dependent on water table elevation, we compared changes in total EPA Method 6200B constituents detected with changes in the water table elevation at wells MW-6, MW-12, and MW-15 (Plates 2 through 4). The petroleum constituent concentrations in well MW-15 decreased when the water table elevation increased (2011 to 2013 and 2015 to 2022). The constituent concentrations increased between 2013 and 2015 and the water table elevation remained unchanged. In well MW-6 we see that the petroleum constituent concentrations initially increased as the water table rose (2011 to 2013) and then decreased during the most recent measured increase in water table elevation (2015 to 2022). In well MW-12 the petroleum constituent concentrations initially increased as the water
table rose (2011 to 2013) and then decreased as the water table elevation decreased between 2013 and 2015. Petroleum constituent concentrations decreased as the water table rose between 2015 and 2022. Our observations over the last four sampling events do not indicate that petroleum constituent concentrations are dependent or controlled by changes in the water table elevation.

There have only been four monitoring events over the last eleven years. The long periods of time between the monitoring events makes evaluating the progress of natural attenuation difficult. The significant decrease in petroleum constituent concentrations measured during the 2022 monitoring event could indicate great progress in the attenuation of contaminant mass within the plume. Data from additional annual
monitoring events is needed to determine if concentrations continue to attenuate or if concentrations are just fluctuating over time. We recommend continuing with the annual natural attenuation monitoring events.

E. Presentation of Current/Historical Site Assessment Information
1. Present current water level and free product thickness measurements (indicating dates, monitoring wells
gauged). Refer to Table B-7 for water level measurements and the date that water levels were measured. A
petroleum sheen was observed in purge water from wells MW-11 and MW-14 on December 13, 2022. A free product measurement was attempted in wells MW-11 and MW-14 with an oil/water interface probe on
December 14, 2022. A measurable amount of free product was not detected so a measurement of <0.01 inches was used. 2. Describe groundwater monitoring events (indicating dates, monitoring wells sampled, screened intervals,
analytical methods). This groundwater monitoring event was conducted on December 13, 2022. The following monitoring
wells were sampled: MW-1, MW-2, MW-4D, MW-5, MW-6, MW-7, MW-8, MW-9, MW-10, MW-12, MW-13 and MW-15. Monitoring wells MW-3 and MW-4 were not found and it appears they have either been removed or paved over. A petroleum sheen was observed in the purge water from monitoring wells MW-11 and MW-14 and these wells were not sampled. The onsite water supply well (UWS) was sampled
and the water supply well on the adjoining property (WSW-1) was sampled. The screened intervals and depth to groundwater for each of these monitoring wells is listed in Table B-7. All water samples were analyzed by EPA Method 6200B. NCDEQ requested that Seramur & Associates not have the samples analyzed by the MADEP VPH and EPH methods this year as the extent of the plume can be determined by the results of the 6200B analysis. The measured depth to the water table was above
the screened interval in wells MW-4D, MW-5, MW-6, MW-8, MW-10, MW-11, MW-12 and MW-13. We do not attribute changes in constituent concentrations to the initial water table being above the screened interval. The water table dropped in each well as three well volumes of water were purged. The groundwater sample collected should be representative of conditions in the aquifer around each well.

3. Describe surface water monitoring events (indicating dates, locations, analytical methods). A surface water sample was collected from Little Buffalo Creek on December 13, 2022 (see Figure 2 for approximate location of sample). The sample was also analyzed for volatile organic constituents using EPA Method 6200B. Volatile constituents were not detected in the surface water sample collected from Little Buffalo Creek.
4. Describe soil monitoring events (indicating dates, sample location and depth, analytical methods). Soil samples were not collected during this monitoring period. 5. Summarize all soil, groundwater, surface water, and free product assessment information acquired to date.

A review of the results of the four most recent monitoring events is discussed above.
6. Describe the geology and hydrogeology of the region and the site. The site is located on approximately 10 feet of fill material southwest of NC Highway 88. The dissolved-phase plume migrates through silty sand and gravel alluvium on the floodplain northeast of NC Highway 88. The site is in the Blue Ridge Geologic Belt of northwestern North Carolina. Bedrock is mapped as gneiss interlayered with schist and amphibolite of the Ashe Formation (Geologic Map of the West Half of the Winston-Salem Quadrangle, NC, VA and TN Rankin et al., 1972, U.S.G.S. Misc. Geol. Invest. Map I-709-A). Groundwater flow at the site is to the northeast toward Little Buffalo Creek (Figure 3 in Section J). The depth to groundwater below the land surface is typically between 8 and 10 feet southwest of NC Highway 88 and 1 to 4 feet on the floodplain of Little Buffalo Creek. Enviromark P.A. estimated the groundwater flow rate at 8 ft/yr (CSA, 11/22/02). Horizontal hydraulic gradient calculated between wells MW-1 and MW-7 was 0.0135 feet per foot during this sampling event.
7. Evaluate soil, groundwater, surface water, and free product assessment information (including field data): Two soil excavation events removed contaminated soil above the water table from the source area. Contaminated soil along the capillary fringe probably exists beneath NC Highway 88 and possibly in the vicinity of monitoring wells MW-11, MW-13 and MW-12. The dissolved phase plume has shrunk
10
considerably since the 2009 sampling event. Evidence of free product detected during this sampling event included a petroleum sheen on the purge water from wells MW-14 and MW-11. Surface water contamination has not been detected from this release. The dissolved-phase contaminant plume extends from the source area across NC Highway 88 past monitoring well MW-6. The contaminant mass cannot be estimated using the individual constituents
measured by EPA Method 6200B. In the past we have used the MADEP VPH/EPH methods to estimate contaminant mass. The current maximum contaminant concentrations occur in wells MW-14 and MW-11 where a petroleum sheen was observed in the purge water from the wells. The applicable cleanup levels for soil, groundwater, surface water, and free product have been not been achieved at this time. F. Free Product Removal
Discuss the status of free product at the site, as follows: 1. If free product is, or has been, present at the site, describe its current and historical status (product distribution, thickness, recovery activities). Prior to 2009, the free product thickness in former well MW-3 ranged from 0.48 feet to 0.84 feet. There
was a period of time in 2003 that daily free product bailing was done by Mr. Ellison and his employees. An MMPE event was successful at recovering 484.08 gallons of product in April 2004. This had little effect on
the free product thickness accumulating in former well MW-3. Two AFVR events have recovered 122.19 gallons of free product from former well MW-3. A passive skimmer was installed in well MW-3 in January 2008 and was maintained by Mr. Ellison and his employees. An MMPE event conducted in December 2008 removed approximately 109.33 gallons of petroleum product from former well MW-3 and adjacent well
MW-14. An MMPE event in March of 2010 recovered 33.92 gallons of product from wells MW-11 and MW-15. The most recent MMPE event was October 2013 and the event recovered 17.52 gallons of product from wells MW-11, MW-12, MW-13, and MW-15. This sampling event detected evidence of free product in the form of a petroleum sheen in the purge water from wells MW-14 and MW-11.
2. Identify any on-site or off-site effluent discharges, treatment used, effluent quality, permitting actions taken, and location of such discharges and identify the disposition of recovered free. There is no effluent discharged on or off-site. Water and product recovered during the past MMPE and AFVR events was transported off-site and disposed of by A&D Environmental. 3. Document the performance, total cost, and cost per gallon to date of each method of free product recovery used at site. Justify why the technology is or was used. AFVR and MMPE events have removed approximately 767.04 gallons of free product as liquid and vapor from the site. The total cost for two AFVR events and four MMPE events is $45,089.25. The cost for this free product recovery was about $58.78/gallon. A passive skimmer was installed in January 2008 at a cost of $1,080.25. 6. Provide conclusions and recommendations concerning historical, current, and future recovery activities, including: The free product recovery efforts were suspended as measurable free product is no longer present.
G. Monitored Natural Attenuation / Natural Source Zone Depletion Status
1. Describe any monitored natural attenuation plan, where implemented, to remediate contaminated soil and groundwater. Include the following: 1) Parameters selected to monitor progress of natural attenuation; At this time annual groundwater monitoring events are proposed to evaluate the progress of natural attenuation. The monitoring program was not implemented during the years 2015-2021, but as of 2022 annual monitoring has resumed.
11
2) Monitoring plan for contaminants in groundwater and natural attenuation parameters (with
proposed sampling locations, analytical methods, sampling frequency, and reporting frequency); Groundwater samples are being analyzed for petroleum constituents using EPA Method 6200B. Groundwater parameters measured during the sampling events include temperature, pH, conductivity and total dissolved solids. Fourteen monitoring wells and two water supply wells are sampled during these
monitoring events. One surface water sample is also collected from Little Buffalo Creek.
3) Reference to historical groundwater monitoring results including estimates for the soil and/or groundwater contaminant mass that is naturally attenuating (in Table 5, below) for initial, historic,
and current estimated mass); The significant decrease in petroleum constituent concentrations since 2015 could indicate that Natural
Attenuation is reducing the petroleum constituent concentrations downgradient of the source area. An estimate of current contaminant mass would require MADEP EPH/VPH or TPH DRO/GRO analyses. Currently these groundwater samples are only being analyzed for individual constituents using EPA Method 6200B.
4) Evaluation of the effectiveness of natural attenuation based on a comparison of the initial
contaminant mass estimates calculated in the Comprehensive Site Assessment with other historic and current contaminant mass estimates, including, where applicable, any modeling/calculation of the apparent mass
attenuation/depletion rate over time in relation to the progress milestones presented in the CAP (Appendix E and J);
Project milestones presented in the CAP will not be achieved. Residual soil and groundwater contamination under NC Highway 88 continues to contribute to petroleum constituent concentrations in the
dissolved-phase plume. A significant decrease in petroleum constituent concentrations since 2015 was documented by this monitoring event. Continued annual monitoring will provide data to evaluate the
effectiveness of natural attenuation over time.
5) Evaluation of the effectiveness of natural attenuation based on a comparison of the initial contaminant mass estimates calculated in the Comprehensive Site Assessment with other historic
and current contaminant mass estimates, including, where applicable, any modeling/calculation of the apparent mass attenuation/depletion rate over time in relation to the progress milestones
presented in the CAP (Appendix E and J); The 2003 CAP proposed 10 years of natural attenuation monitoring for a cost of $45,132. The free
product recovery efforts alone have cost just under this estimate. This report is being written almost 20 years after the CAP and eleven monitoring events have been completed. A total of $6,061 was approved for this
sampling event which included an updated receptor survey. An additional 10 years of natural attenuation monitoring can be completed for about $5,000/year.
This could be the most cost-effective remediation option and it allows the potential receptors to be
monitored. If measurable free product is detected in the future, it may be necessary to complete another free product recovery event.
6) Based on a schedule defined in the CAP, an evaluation of plume stability based on modeling of groundwater analytical and natural attenuation parameter results (Appendix C).
See number 5 above.
H. Conclusions
The significant decrease in petroleum constituent concentrations since 2015 could indicate that Natural Attenuation is reducing the petroleum constituent concentrations downgradient of the source area. Seramur
& Associates recommends continued annual monitoring events to evaluate changes in petroleum constituent concentrations over time and to ensure that water quality at the three potential receptors has not been compromised.

I. Statements and Certification
The following statements must be included at the closing of the document text, and must display the seal and signature of the certifying P.E. or L.G. in addition to the name and certification number of the company or corporation [See 15A NCAC
2L .0103(e).]
1 Enter the date the monitoring report was due. 1/18/2023 Will this report be submitted after the established due date?
YES
2 Was any required information from the above template missing from this report? NO
IF the answer to question #1 or# 2 is “YES”, please provide additional information in this cell to
explain what was missing and why.
3 If applicable, will any of the proposed attenuation milestones under the schedule approved in the Corrective Action Plan not be met? (within a reasonable margin of error)
YES
It is likely that residual contaminated soil is present under NC Highway 88. To date, it has not
been possible to address the contaminant plume under the highway.
4 Does any known or suspected source zone soil contamination or free product remain outside of the assessed area that could be inhibiting natural attenuation? Possibly under NC Highway 88.
Possibly
5 Has there been an unexpected increase in contaminant mass sufficient to suggest a potential new release from a separate onsite or offsite source? NO
Addressing the potential for free product or residual contaminated soil under NC Highway 88 may
not be possible.
