Ground Water Monitoring Report Prepared on: August 4, 2020 Noah Roberson Store Project Manager: William Regenthal, P. G. GRI Project No. 2319 ii EXECUTIVE SUMMARY The Noah Roberson Store site is located at 8941 NC Highway 171 in Williamston, Martin County, North Carolina. The site is currently owned by James and Bertie Hardison and is currently closed. The site formerly operated as a petroleum retail facility. According to available information, one 1,000-gallon gasoline and two 550-gallon gasoline underground storage tanks (USTs) and associated pumps and product piping were removed from the site in December 1993. The adjoining properties are residential or agricultural properties. Public water is available to the site and surrounding properties within a 1,500- foot radius of the site. A Corrective Action Plan proposing a ground water pump and treat system was developed for the site. This system was installed activated in March 1999. The remediation system was shut down between January and September 2005 due to lack of funding from the NCDEQ UST Trust Fund. The remediation system was restarted and operated at the site between July 2009 and January 2012. On July 15, 2020, five monitoring wells and one water supply well were gauged, purged and sampled. Monitoring wells MW-6 and MW-22 were not located. No free product was observed in the monitoring wells prior to sampling. The Maximum Allowable Concentrations (MACs) as specified in T15A NCAC 2L.0202 were below the concentrations of benzene, xylenes, naphthalene, isopropylbenzene, n- propylbenzene and/or 1,2,4-trimethylbenzene reported in the ground water samples collected from MW- 1, MW-3, MW-5, MW-12 and MW-13. All of the reported contaminant concentrations were below the Gross Contamination Levels. A Mann-Kendall plume stability analysis was completed for the site in July 2020. Overall, the contaminant plume is generally stable or decreasing at the site. No trend could be established for xylenes and naphthalene concentrations in MW-1 and MW-3, and naphthalene appears to be increasing in MW-13. Contaminant mass at the site has decreased 48% between March 2012 and July 2020. Based on this information, the site risk classification should be re-evaluated. In the meantime, semi- annual ground water monitoring should continue at the site. The next sampling event is tentatively scheduled for January 2021. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc.

Ground Water Monitoring Report Prepared on: August 4, 2020 Noah Roberson Store Project Manager: William Regenthal, P. G. GRI Project No. 2319 1 1.0 SITE HISTORY AND CHARACTERIZATION Geological Resources, Inc. (GRI) presents the results of the October 2019 ground water sampling event at the Noah Roberson Store site; located at 8941 NC Highway 171 in Williamston, Martin County, North Carolina (Figure 1). These activities were conducted in accordance with GRI Proposal No. 20-379, which was submitted to the North Carolina Department of Environmental Quality (NCDEQ) on July 6, 2020, and was approved as Task Authorization No. 11759-55 on July 9, 2020. NCDEQ correspondence associated with the incident is included as Appendix A. The site is currently owned by James A. and Bertie H. Hardison and is currently closed. The site formerly operated as a petroleum retail facility. According to available information, one 1,000-gallon gasoline and two 550-gallon gasoline underground storage tanks (USTs), associated pumps and product piping were removed from the site in December 1993. UST owner/operator information and UST system information are included as Tables 1 and 2, respectively. The Registered Tank Report is shown below: The site and surrounding area are a mixture of residential and agricultural properties. The site contains one building and is primarily capped with gravel and grass. The overall topography at the site is relatively flat. Roadside and agricultural ditches were identified within a 500-foot radius of the site. Twenty-two Type II monitoring wells (MW-1, MW-2, MW-3 and MW-5 through MW-23) and one Type III monitoring well (MWD-4) were installed at the site during previous ground water assessment and corrective action activities. Two recovery wells (RW-1 and RW-2) were also installed during corrective action implementation activities. Two replacement monitoring wells (MW-8R and MW-16R) were installed in order to replace previously destroyed wells MW-8 and MW-16. Municipal water is available to the site and surrounding properties. An updated receptor survey was conducted for this site in August 2014. One water supply well (WSW-1) was identified within a 250-foot radius of the site. Two potable water supply wells (WSW-2 and WSW-4) were identified within a 1,000- foot radius of the site. The owner of WSW-1 has refused to abandon their well on multiple occasions.

A Site Vicinity Map showing the locations of water supply wells and property boundaries is included as Figure 3. Adjacent property owner information is included in Table 3. Water supply well information is presented in Table 4. A Corrective Action Plan proposing the installation of a ground water pump and treat system was developed for the site. This system was installed and activated in March 1999. The remediation system was shut down between January and September 2005 due to lack of funding from the NCDEQ UST Trust Fund. The remediation system was restarted and operated at the site between July 2009 and January 2012. 2.0 PRESENTATION OF CURRENT SITE ASSESSMENT INFORMATION/ COMPARISON TO HISTORICAL ASSESSMENT INFORMATION On July 15, 2020, five Type II monitoring wells (MW-1, MW-3, MW-5, MW-12 and MW-13) and one water supply well (WSW-1) were gauged, purged and/or sampled. Monitoring wells MW-6 and MW-22 were not located. Depths to ground water in the Type II monitoring wells ranged from 1.82 feet to 3.59 feet below the tops of well casings. Ground water flow direction was generally toward the north with an average hydraulic gradient of approximately 0.03 feet per foot. Well construction and gauging information is presented in Table 5. A Water Table Surface Map based on the July 2020 gauging data is included as Figure 4. A summary of the current ground water gauging data is shown below: Well ID Screened Interval (x to y ft.

Ground Water Monitoring Report Prepared on: August 4, 2020 Noah Roberson Store Project Manager: William Regenthal, P. G. GRI Project No. 2319 4 A Corrective Action Plan, proposing the installation of a ground water pump and treat system, was submitted for the site on January 13, 1997. The corrective action system was installed and activated at the site in March 1999. The remediation system was shut down between January and September 2005 due to lack of funding from the NCDEQ UST Trust Fund. The remediation system was restarted and operated at the site between July 2009 and January 2012. No contaminant milestones were established in the CAP. A GSI Mann-Kendall Toolkit for Constituent Trend Analysis was prepared using historical concentrations of benzene, xylenes and naphthalene in MW-1, MW-3, MW-5, MW-12 and MW-13 between the September 2008 and July 2020 sampling events. No trend could be established for xylenes and naphthalene concentrations in MW-1 and MW-3. The concentrations of benzene and xylenes are stable, decreasing and/or probably decreasing in MW-1, MW-3, MW-5, MW-12 and MW-13. The concentrations of naphthalene appear to be increasing in MW-13. Copies of each GSI Mann-Kendall Toolkit for Constituent Trend Analysis used for benzene, xylenes and naphthalene are included as Appendix D. The site is located in the Coastal Plain Physiographic Province of North Carolina. The water table has a seasonal high depth to water of approximately 1 to 16 feet below ground surface (bgs). 3.0 FREE PRODUCT REMOVAL Historically free product has not been observed at the site. Between August 2010 and December 2012, two MMPE events have been conducted at the site. 4.0 NATURAL ATTENUATION / NATURAL SOURCE ZONE DEPLETION STATUS No natural attenuation monitoring plan is currently in place at the site. 5.0 CONCLUSIONS  On July 15, 2020, five Type II monitoring wells and one water supply well were gauged, purged and/or sampled. Ground water flow direction was generally toward the north with an average hydraulic gradient of approximately 0.03 feet per foot.  The MACs were below the concentrations of benzene, xylenes, naphthalene, isopropylbenzene, n-propylbenzene and/or 1,2,4-trimethylbenzene reported in the ground water samples collected from MW-1, MW-3, MW-5, MW-12 and MW-13. All of the reported contaminant concentrations were below the GCLs.  The contaminant mass at the site has been reduced by 48% since the CAS was shut down in January 2012. The remediation system should be removed from the site.  A Mann-Kendall plume stability analysis was completed for the site in July 2020. Overall, the contaminant plume is generally stable or decreasing at the site. No trend could be established for xylenes and naphthalene concentrations in MW-1 and MW-3, and naphthalene appears to be increasing in MW-13. Contaminant mass at the site has decreased 48% between March 2012 and July 2020. ___________________________________________________________________________________________ Prepared by: Geological Resources, Inc.

ATTN: Mr. Lars Simonsen Simonsen Law Firm Post Office Box 848 Edenton, North Carolina 27932 Re: Notice of Regulatory Requirements 15A NCAC 2L .0407 Risk-based Assessment and Corrective Action for Petroleum Underground Storage Tanks Acknowledgement of Report Receipt Noah Roberson Store 8941 NC Hwy 171, Williamston, NC Martin County Incident Number: 11759 Risk Classification: High Ranking: H 142 D Dear Mr. Simonsen: The Division of Waste Management (DWM) Underground Storage Tank (UST) Section received the Groundwater Monitoring Report (Report) dated October 25, 2019. The report has been reviewed and will be maintained in the Washington Regional Office. The report indicates continued levels of groundwater contamination. The subject incident has been determined by the Department, in response to North Carolina General Statute (NCGS) 143-215.94E(e4), to be of sufficiently high priority to allow funding by the State Trust Fund Program. Therefore, you are directed to proceed with assessment. Specifically, you are required to:  Continue to monitor groundwater quality on a nine-month schedule.  Submit monitoring report within 30 days of receiving the analytical results. The next sampling event should be conducted in July 2020. Effective October 1, 2004, the Department requires that all work following the submittal of the Limited Site Assessment Report (Title 15A NCAC 2L .0405) be preapproved if State Trust Fund reimbursement is anticipated. To comply with this requirement, a completed Preapproval/Claim Authorization Form, encompassing the required remedial activities, must be received in this office within 14 days of the date of this letter. Upon completion of the preapproved activities, you should submit your claim promptly. Reimbursement funds are budgeted based on completed preapprovals, but lengthy delays in reimbursement can occur if claims are not submitted immediately following work completion. Because a release or discharge has been confirmed, a Licensed Geologist or a Professional Engineer, certified by the State of North Carolina, is required to prepare and certify all reports submitted to the Department in accordance with Title 15A NCAC 2L .0103(e) and 2L .0111(b). Please note that before you sell, transfer, or request a “No Further Action” determination for a property that has not been remediated to below “unrestricted use” standards, you must file a Notice of Residual Petroleum ("Notice") with the Register of Deeds in the county where the property is located (NCGS 143B-279.9 and 143B-279.11). Failure to comply with the State's rules in the manner and time specified may result in the assessment of civil penalties and/or the use of other enforcement mechanisms. If you have any questions regarding the actions or the rules mentioned in this letter, please contact me at the address or telephone number listed below. If you have any questions regarding trust fund eligibility or reimbursement, please contact the UST Section Trust Fund Branch at (919) 733-8486.

Decreasing Increasing Notes: 1.At least four independent sampling events per well are required for calculating the trend. Methodology is valid for 4 to 40 samples. 2.Confidence in Trend = Confidence (in percent) that constituent concentration is increasing (S>0) or decreasing (S<0): >95% = Increasing or Decreasing; ≥ 90% = Probably Increasing or Probably Decreasing; < 90% and S>0 = No Trend; < 90%, S≤0, and COV ≥ 1 = No Trend; < 90% and COV < 1 = Stable. 3.Methodology based on "MAROS: A Decision Support System for Optimizing Monitoring Plans", J.J. Aziz, M. Ling, H.S. Rifai, C.J. Newell, and J.R. Gonzales, Ground Water, 41(3):355-367, 2003. DISCLAIMER: The GSI Mann-Kendall Toolkit is available "as is".
