INJECTION ZONE MAPS — Attach the following to the notification. (1) Contaminant plume map(s) with isoconcentration lines that show the horizontal extent of the contaminant plume in soil and groundwater, existing and proposed monitoring wells, and existing and proposed injection wells; and (2) Cross-section(s) to the known or projected depth of contamination that show the horizontal and vertical extent of the contaminant plume in soil and groundwater, changes in lithology, existing and proposed monitoring wells, and existing and proposed injection wells. (3) Potentiometric surface map(s) indicating the rate and direction of groundwater movement, plus existing and proposed wells. L DESCRIPTION OF PROPOSED INJECTION ACTIVITIES AT THE SITE — Provide a brief narrative regarding the cause of the contamination, and purpose, scope, goals of the proposed injection activity: The Site, Travel Centers of America — Candler is currently an active commercial petroleum fueling facility. Several documented releases of gasoline and diesel have occurred at the site over many years with free product discovered in monitoring well MW-15. The purpose of this project is to perform a Mobile Multi -Phase Extraction (MMPE) with Surfactant Injection on MW-15. The MMPE system will be set up for prior and post injection to simultaneously remove vapors and liquids from the subsurface of the Site and convey the contaminants to a designated container. The solution. Ivey -Sol 9103 will be injected at 2% with water to absorb the petroleum hydrocarbons in the monitoring well and groundwater plume. Following this procedure, groundwater sampling will take place 30 days after the event, aiming to remediate the level of petroleum hydrocarbon in the groundwater. J.

L. MONITORING PLAN — Describe below or in separate attachment a monitoring plan to be used to determine if violations of groundwater quality standards specified in Subchapter 02L result from the injection activity. Approximately 30 days after completion of the Limited Injection/NIMPE event, AECOM will mobilize to the site to collect a confirmatga groundwater sample from monitoring well MW-15 to evaluate the effectiveness of the Limited Jection/MMPE event. Prior to sampling, groundwater levels will be measured at all on -site monitoring wells. The groundwater sample will be collected using a dedicated bailer and a minimum of three well volumes will be purged prior to sampling. One duplicate sample will be collected during the sampling event for quality assurance purposes. The groundwater samples will be shipped to a North Carolina certified laboratory via overnight courier and analyzed by EPA Method SM6200 for a targeted list of anal qes including benzene, toluene, ethylbenzene, xylenes_(BTEX), 1.2-dichloroethane (1.2-DCA), ethylene dibromide (EDB), isopropyl ether (IPE), methyl tert-butyl ether (MTBE), and naphthalene.

The remedial strategy proposed in the Monitoring Report has been reviewed and approved by the UST Section. Please proceed with the Feasibility Study which includes a pilot study for chemical injection using BOS 200 or a similar approved product. The review indicates that corrective action is necessary to remediate environmental contamination. Title 15A NCAC 02L .0407 (d) [Intermediate Risk] requires you to comply with the assessment and cleanup requirements of Title 15A NCAC 2N .0707 and Title 15A NCAC 02L .0106(c) and 02L .01 11(c). In accordance with 15A NCAC 02L .0111(a), a Corrective Action Plan shall be submitted to this office in accordance with a schedule established by the Division of Waste Management Director. Because this incident is eligible (or potentially eligible) for access to the Commercial Leaking Petroleum Underground Storage Tank Cleanup Fund (State Trust Fund), a Feasibility Study in accordance with the most recent version of the UST Section Corrective Action Guidelines, and the applicable State Trust Fund Reasonable Rate Document must be submitted instead of a completed CAP. The Section must approve the proposed remedial strategy prior to conducting a Feasibility Study. In the CAP, natural attenuation of groundwater contamination must be used to the maximum extent possible, plume stability should be evaluated, and efforts must be made to determine whether the elimination of potential receptors, leading to risk reduction, is immediately practicable. A responsible party who submits a Corrective Action Plan that proposes natural attenuation at any point in the process or cleanup to alternate standards must provide public notice as specified in 15A NCAC 02L .0409(a).

The Department of Environmental Quality requires that all work not determined to be an emergency response or associated with risk assessment (i.e., the Limited Site Assessment Report, per Title 15A NCAC 02L .0405) must be preapproved if State Trust Fund reimbursement is anticipated. To comply with this requirement, a completed Preapproval/Claim Authorization Form, encompassing the scope of work necessary to evaluate the feasibility of a proposed remediation strategy, must be received in this office within 14 days of the date of this letter. Upon completion of preapproved activities that define an individual step within the Corrective Action Plan process, you should submit your claim promptly. Reimbursement funds are budgeted based on completed preapprovals, but delays in reimbursement or even denial due to a failure to meet the statute of limitations on claiming a completed task can result if the work is not completed in a timely fashion or of claims are not submitted immediately following work completion. 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.
