The reports were reviewed and approved on February 11, 2020 and January 31, 2020. The paper report copies will be maintained in the MRO. The electronic copies have been loaded to the DWM's electronic document storage system (Laserfiche). The report states: • Site remediation was performed via the soil vapor extraction and air sparge systems activated on April 18, 2012 (shut down in August 2019). • On December 19, 2019, Apex collected groundwater samples from twelve monitoring wells (MW-9, MW-11, MW-12, MW-14, MW-17, MW-20, MW-21, MW-22, MW-23, MW-24, MW-25, and DMW-3). The dissolved -phase endpoint for benzene of 1.0 µg/L was exceeded in monitoring well MW-23. The dissolved -phase endpoint for MTBE of 20 µg/L was exceeded in monitoring wells MW-9, MW-14 and MW-23. • Free product was not detected in any groundwater monitoring wells gauged during this phase. North Carolina Department of Environmental Quality I Division of Waste Management Mooresville Regional Office 1 610 East Center Avenue, Suite 301 1 Mooresville, North Carolina 28115 704.663.1699 • Groundwater flow direction beneath the site is influenced by water table depression and mounding created by system operation at the recovery/sparge wells. Historical groundwater flow direction has been measured to the north-northwest. • Apex also collected groundwater samples from six supply wells (5922, 5925, 5927, 5955 Turkey Road and 2847 and 2865 Lane Street). Petroleum compounds have never been detected in potable water supplies. Tetrachloroethene at a concentration of 2.18 µg/L was detected in supply well SW-5922 (consistent with the previous sampling events). Sentinel wells MW-21, MW-22, and MW-25 continue to indicate that the gasoline plume is confined to the original source zone identified and described in both the CSA and approved CAP. • Mass balance calculations of remaining benzene and MTBE at the site show less than one - tenth gram of combined MTBE and benzene remain onsite as a result of the incident. Additionally, a mass reduction for MTBE and benzene of 99.9% has been accomplished with the remediation system. Per this Notice of Regulatory Requirements: • The remediation system shall remain off. The system must be properly maintained and the switch ready in case future use is necessary. • Continue semi-annual groundwater sampling/monitoring. • Install and sample two monitoring wells between the site and potable residential water supply wells for the next sampling event. • The next sampling event for the Monitoring Report shall be conducted in June 2020. No Corrective Action Performance Report is required to be submitted when the treatment system is off per NCDEQ directive. The next Monitoring Report is due no later than July 31, 2020. Please note that sampling and correction action must be conducted in accordance with the Guidelines for Assessment and Corrective Action for UST Releases. Failure to comply in the manner and time specified may result in the assessment of civil penalties and/or the use of the other enforcement mechanisms.
