It has been determined that additional assessment information is needed to help determine the potential risk of exposure to potable water supply wells identified in the LSA. The risk posed by the discharge or release at the subject site is classified by the Department of Environmental Quality as high, as stipulated under Title 15A NCAC 2L .0406, due to as many as eight potable water supply wells within 1,000 feet of the source area of a confirmed discharge or release from a commercial UST. The land use at the site is classified as residential. Please note that Title 15A NCAC 2L .0407(a) requires you to notify the Department of any changes that might affect the risk or land use classifications that have been assigned. Title 15A NCAC 2L .0407(c) [High Risk] requires you to comply with the assessment and cleanup requirements of Title 15A NCAC 2N .0706 and Title15A NCAC 2L .0106(c) and 2L .0111(b). Failure to comply in the manner and time specified may result in the assessment of civil penalties and/or the use of other enforcement mechanisms. Please submit an Additional Risk Assessment (ARA) Report within 90 days of this notice. This report supplements the LSA through the assessment of groundwater characteristics and the risk to nearby receptors. Specifically, the ARA should include, at a minimum: • The installation of three horizontal extent monitoring wells. One monitoring well shall be installed upgradient of the source of contamination and two monitoring wells shall be installed downgradient of the source of contamination, as best as can be determined, and located such that groundwater flow direction and hydraulic gradient may accurately be determined. • The analysis of representative soil samples collected during the construction of the monitoring wells. One soil sample must be collected in the unsaturated zone and one in the smear/saturated zone from suspected worst-case locations exhibiting visible contamination or elevated levels of volatile organic compounds based on field screening techniques. Only the suspected most contaminated soil sample in each zone from each boring should be submitted for laboratory analysis using the EPA 8015B TPH (or equivalent) appropriate for the fuel types suspected in the release.

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 15A NCAC 2L .0103(e) and 2L .0111(e). 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. 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). If you have any questions regarding trust fund eligibility or reimbursement from the Commercial Leaking Petroleum Underground Storage Tank Cleanup Fund, please contact the UST Section Trust Fund Branch at (919) 707-8171. If you have any questions regarding the actions that must be taken or the rules mentioned in this letter, please contact me at the address or telephone number listed below. Sincerely, Kenneth E.
