Delivery) June 27, 2023 North Carolina Department of Environmental Quality Division of Water Resources Water Quality Regional Operations Section 610 East Center Avenue, Suite 301 Mooresville, NC 28115 Attn: Mr. Andrew Pitner, PG Mr. Wesley Bell Re: Surface Water Sampling Results Charlotte Douglas International Airport Airport Drive Release Charlotte, North Carolina NC DEQ UST Section Incident #18989 H&H Job No. CDA-044 Dear Mr. Pitner and Mr. Bell: On behalf of Charlotte Douglas International Airport (CLT), Hart & Hickman, PC (H&H) is providing results of recent surface water sampling activities conducted in association with the jet fuel release from the aboveground storage tank (AST) system at the CLT Wilson Air Center General Aviation Fuel Farm located at 5414 Airport Drive in Charlotte (hereafter referred to as the Site). The North Carolina Department of Environmental Quality (DEQ), Division of Waste Management (DWM), Underground Storage Tank (UST) Section incident identification number for the Site is #18989. A Site location map is included as Figure 1, and a Site map is included as Figure 2. CLT personnel observed evidence of petroleum seepage from the bank of an unnamed tributary of Taggart Creek on property owned by the City of Charlotte at CLT on September 17, 2019. Since that time, initial emergency response actions, absorbent boom and pad maintenance, and several https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Douglas International Airport - CDA/CDA-044 Airport Drive Release/SW Sampling/June 2023/Surface Water Sampling Results_June 2023.docx Mr. Andrew Pitner, PG and Mr. Wesley Bell Airport Drive Release (Incident #18989) June 27, 2023 Page 2 phases of assessment and petroleum free product or light non-aqueous phase liquid (LNAPL) removal activities have been conducted by or on behalf of CLT. On April 1, 2021, as an interim measure, while additional assessment and preliminary LNAPL removal activities were being conducted, H&H submitted a BIOREM-2000 Oil Digester Application Request to DEQ’s UST Section and members of DEQ’s Division of Water Resources (DWR) to obtain agency concurrence for the use of BIOREM-2000 Oil Digestor™ (BIOREM) to treat various surfaces (i.e., stream banks, vegetation, water surfaces, etc.) affected by the jet fuel release. On May 12, 2021, DEQ’s DWR conditionally approved the application of BIOREM to treat various surfaces affected by the release contingent upon application of the product in accordance with the manufacturer’s instructions and below a dosage rate of 8.8 milligrams per liter (mg/L). DEQ DWR also required the implementation of a quarterly stream sampling schedule for the unnamed tributary of Taggart Creek. In accordance with DEQ’s DWR request, H&H initiated quarterly surface water sampling activities in the unnamed tributary of Taggart Creek in May 2021. The baseline surface water sampling event was conducted on May 21, 2021, followed by application of BIOREM to treat various affected surfaces on June 4, 2021, and post-application surface water sampling on June 7, 2021. The results of the May 2021 baseline surface water sampling event and June 2021 post-application surface water sampling event were provided to DEQ’s DWR and UST Section in H&H’s Surface Water Sampling Results letter report dated June 30, 2021. Since that time, BIOREM has been directly applied to oily surfaces including stream banks, vegetation, and surface waters typically once a week with a hand sprayer in accordance with the manufacturer’s instructions and below a dosage rate of 8.8 mg/L. Vegetation is currently present on the banks in the vicinity of the petroleum seeps where it was previously sparse. In March 2022, H&H requested that the quarterly surface water monitoring schedule be reduced to a semi-annual frequency based on the lack of target compounds above applicable standards or screening values in the downstream portion of the unnamed tributary during the previous four https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Douglas International Airport - CDA/CDA-044 Airport Drive Release/SW Sampling/June 2023/Surface Water Sampling Results_June 2023.docx Mr. Andrew Pitner, PG and Mr. Wesley Bell Airport Drive Release (Incident #18989) June 27, 2023 Page 3 monitoring events. Furthermore, based on the lack of detection of RCRA metals above applicable standards or screening values in the unnamed tributary of Taggart Creek during the previous four monitoring events, H&H requested that Resource Conservation Recovery Act (RCRA) metals analysis be eliminated from the surface water sampling program during future monitoring events. On April 1, 2022, DEQ’s DWR agreed that metals sampling could be discontinued from the surface water sampling program but indicated that quarterly surface water monitoring must be continued due to petroleum sheens observed in the unnamed tributary of Taggart Creek in February 2022. Although it appears that the BIOREM has been effective in treating oily surfaces on vegetation and stream banks, petroleum sheens continue to be observed occasionally in the unnamed tributary of Taggart Creek. The results of the recent quarterly surface water sampling activities conducted on June 5, 2023 are discussed below. The June 2023 surface water sampling event was conducted during apparent base flow conditions and included the collection and analysis of upstream and downstream surface water samples. The location of the surface water samples (denoted by “SW” nomenclature) are depicted in Figure 3. These samples were collected in the following locations: •Upstream portion of the unnamed tributary of Taggart Creek above the BIOREM application areas (SW-Upstream); and •Downstream portion of the unnamed tributary of Taggart Creek below the BIOREM application areas (SW-Downstream). The surface water samples were collected in a downstream to upstream order during the sampling event. Surface water samples were collected by lowering laboratory-supplied sample containers into the center portion of the stream with the containers facing upstream and without disturbing sediments. Surface water samples were labeled with the sample identification, date, and requested analysis; and placed in a laboratory-supplied cooler with ice. The surface water samples were delivered to Waypoint Analytical, LLC of Charlotte, North Carolina under standard chain of custody protocols for analysis of volatile organic compounds (VOCs) by EPA Method 8260, semi- https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Douglas International Airport - CDA/CDA-044 Airport Drive Release/SW Sampling/June 2023/Surface Water Sampling Results_June 2023.docx Mr. Andrew Pitner, PG and Mr. Wesley Bell Airport Drive Release (Incident #18989) June 27, 2023 Page 4 volatile organic compounds (SVOCs) by EPA Method 8270, and extractable petroleum hydrocarbons (EPH) and volatile petroleum hydrocarbons (VPH) by the Massachusetts Department of Environmental Protection (MADEP) Methods. The June 2023 and historical surface water sampling results are summarized in Table 1. Copies of the laboratory analytical report and chain of custody record for the June 2023 sampling event are provided in Attachment A. Taggart Creek is classified as a Class C surface water body (i.e., waters protected for uses such as secondary recreation, fishing, wildlife, fish consumption, aquatic life including propagation, survival and maintenance of biological integrity, and agriculture). Therefore, surface water sample results were compared to the most stringent of the freshwater and human health 15A NCAC 02B Surface Water Quality Standards (2B Standards) amended September 1, 2022 for a Class C surface water body. In instances where a compound had no established 2B Standard, the surface water sample results were compared to the EPA Nationally Recommended Water Quality Criteria (NRWQC) screening values dated July 2016. In instances where a compound had no established 2B Standard or EPA NRWQC screening value, the surface water sample results were compared to North Carolina In-Stream target values for surface waters dated July 2016. The only compounds detected in the surface water samples were low estimated concentrations of aliphatic hydrocarbons as EPH C9-C18 in the downgradient sample and aliphatic hydrocarbons as EPH C9-C18 and aromatic hydrocarbons as C11-C22 in the upgradient sample. The detected estimated concentrations of aliphatic hydrocarbons as EPH C9-C18 in the upgradient and downgradient samples (30.3 J µg/L and 33.8 J µg/L) were below its North Carolina In-Stream target value of 180 µg/L. The detected estimated concentration of aromatic hydrocarbons as EPH C11-C22 in the upgradient sample was 64.4 J µg/L. There are no established water quality standards for aromatic hydrocarbons as EPH C11-C22. It should be noted that both of these constituents were detected in the laboratory blank. https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Charlotte Douglas International Airport - CDA/CDA-044 Airport Drive Release/SW Sampling/June 2023/Surface Water Sampling Results_June 2023.docx Mr. Andrew Pitner, PG and Mr. Wesley Bell Airport Drive Release (Incident #18989) June 27, 2023 Page 5 H&H submitted a Free Product Corrective Action Plan (CAP) and remedial design to DEQ on October 11, 2021. The Free Product CAP proposed dual phase extraction (DPE) as a dedicated system to remove the free product. DEQ approved the October 11, 2021 Free Product CAP in a letter dated December 1, 2021. The proposed DPE recovery wells were installed at the Site in June 2022. DEQ approved the National Pollutant Discharge Elimination System General Permit for the dedicated DPE system at the end of July 2022. DPE system fabrication work began in April 2022, and field construction activities began in July 2022. The DPE system equipment was delivered to the Site on October 26, 2022 and field construction activities were completed in late December 2022. Following the establishment of electric services at the Site by Duke Energy in mid-January, DPE system startup was conducted between January 23 and 25, 2023. Since that time, as of the writing of this letter, the DPE systems have operated at the Site for approximately 117 days. Details of DPE system installation and performance, including NPDES effluent sampling and LNAPL recovery are being provided to DEQ under separate cover. Initial results indicate that free product levels in monitoring wells near the creek have decreased as a result of the DPE systems.

The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method. The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance. The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as- received basis unless otherwise indicated.
