A site location map is provided as Figure 1. This report also includes a summary of analytical results for the annual private water supply well sampling performed in August 2018. Apex Companies, LLC (Apex; dba Apex Engineering, P.C.) prepared this Semiannual Groundwater Monitoring Report on behalf of CPC for submittal to the North Carolina Department of Environmental Quality (NCDEQ), Underground Storage Tank Section. 2.0 PROJECT BACKGROUND The facility consists of a control building, a switch gear building, eight large electric booster pumps, a 40-inch diameter pipeline for transporting gasoline products (Line 1), a 36-inch diameter pipeline for transporting kerosene, diesel fuel and other fuel oil products (Line 2), two 21,000-gallon above ground storage tanks and associated above -ground and below -ground piping and valves. The facility has been in operation since the 1970s. 2.1 Historic Site Impacts Formal assessment and remediation activities were initiated at the facility in 1995. Three areas of concern were identified at the facility including (1) the Line 2 Manifold Area; (2) the Line 1 Manifold Area; and, (3) the Line 1 Pig Signal Area. Impacts identified during the 1995 assessment are included in Incident Number 14414. Historic petroleum impacts in the Line 2 Manifold Area are the result of a kerosene release. Excavation of impacted soils was limited due to the presence of pumps, footings, and associated underground piping and valves. A light non -aqueous phase liquid (LNAPL) recovery system and a soil vapor extraction (SVE) system were installed in this area. A dissolved phase plume consisting of gasoline -related compounds was identified in the Line 1 Manifold Area. A limited amount of impacted soil was excavated in this area and an SVE system was installed. APEX Semiannual Monitoring Report, March 2018-August 2018 October 1, 2018 Colonial Pipeline Company, Kannapolis Booster Station Page 2 Gasoline impacted soil was also identified in the Line 1 Pig Signal Area as a result of a release from a leaking pipe fitting. Approximately 1,000 tons of soil was excavated and thermally treated in this area. The excavation extended to bedrock, removing the source material; however, the release resulted in dissolved phase groundwater impacts. An air sparge trench located near the downgradient property boundary and a non -discharge pump and treatment system were installed in the late-1990s to prevent off -site migration of petroleum hydrocarbons. The air sparge trench is currently in operation. The groundwater pump and treatment system was taken off-line in April 2010, following approval from NCDEQ on April 12, 2010. The LNAPL recovery and SVE systems were taken off-line in October 2010, following approval from NCDEQ on September 29, 2010. 2.2 Recent Site Impacts A 920-gallon petroleum release occurred at the site on March 13, 2015 when a valve gasket failed near the Line 2, Unit 4 booster pump. Emergency response and abatement activities were performed from March 13, 2015 through August 11, 2015. On August 13, 2015, a three -quarter -inch nipple on Line 2 was struck by a piece of equipment during backfilling operations resulting in a 5,000- gallon petroleum release over the recently remediated area. Approximately 4,750 gallons of diesel fuel were recovered during initial response activities and subsequent recovery well evacuation efforts. Residual soil impacts were detected at areas where additional excavation was not feasible due to the presence of booster pumps, footings, and associated underground piping and valves. Approximately 750 tons of petroleum -impacted soil was removed from the release area during the initial response activities associated with both 2015 releases. Impacts identified during the 2015 assessment are included in Incident Number 91340. A Corrective Action Plan (CAP) and CAP Addendum were submitted to NCDEQ on April 15, 2016 and July 12, 2016, respectively. The CAP documents specified installation and operation of a bio- venting and bio-sparge system to address residual soil impacts and dissolved phase groundwater impacts. The CAP was approved on May 6, 2016 and the CAP Addendum was approved on July 28, 2016. The semiannual groundwater monitoring program for the site incorporates the groundwater monitoring programs associated with Incident Numbers 14414 and 91340. A summary of the Groundwater Monitoring Program for the site is provided as Table 1. APEX Semiannual Monitoring Report, March 2018-August 2018 October 1, 2018 Colonial Pipeline Company, Kannapolis Booster Station Page 3 3.0 GROUNDWATER SAMPLING FIELD ACTIVITIES The following tasks were performed at the site from March 2018 through August 2018 summarized in this report: • Performed semiannual groundwater monitoring event on August 16, 2018; • Performed private water supply well sampling on August 23, 2018; • Operated air sparge trench remediation system near downgradient property boundary; and, • Operated biosparge and bioventing remediation system in the distillate manifold. 3.1 Groundwater Gauging Prior to sampling, groundwater monitoring wells were gauged to measure the depth to groundwater and LNAPL, if present. Upon arriving at the site, wells were opened and allowed to equilibrate. Wells were gauged in accordance with the United States Environmental Protection Agency (USEPA) Region IV Science and Ecosystem Support Division Field Branches Quality System and Technical Procedures. The wells were gauged in order of potential impact, moving from upgradient wells, to downgradient wells and finally source area wells. Depths to groundwater and LNAPL were measured using an electronic oil/water interface probe capable of measuring to an accuracy of 0.01 feet. The interface probe was thoroughly decontaminated before collecting measurements at each subsequent monitoring well. A total of ten monitoring wells (MW-1, MW-4, MW-5, MW-6, MW-8, MW-13, MW-23, MW-24, MW-25, and MW-25D) and 12 recovery wells (SB- 4, SB-6, SB-8, S13-9, S13-10, S13-11, S13-12, S13-14, S13-15, S13-16, S13-18, and RW-1 were gauged during the August 2018 monitoring event. Recovery well RW-2 was not located during the gauging event. The monitoring well and recovery well locations are shown on Figure 2 and Figure 3, respectively. 3.2 Groundwater Sampling and Analysis Groundwater samples were collected from seven monitoring wells (MW-4, MW-6, MW-8, MW-13, MW-24, MW-25, and MW-25D) during the August 2018 monitoring event. At each monitoring well, a baseline set of water quality stabilization data was measured (temperature, specific conductance, pH, oxidation reduction potential, dissolved oxygen, and turbidity), and recorded. The total volume of water in each well was calculated and approximately three well volumes were purged from each well. APEX Semiannual Monitoring Report, March 2018-August 2018 October 1, 2018 Colonial Pipeline Company, Kannapolis Booster Station Page 4 A complete set of parameter readings were recorded in -situ each time one well volume was purged. Monitoring wells were purged and sampled with disposable bailers. Groundwater sampling logs documenting the groundwater monitoring well purging and sampling are provided as Appendix A. After purging an adequate volume of water from each well, a sample was retrieved and transferred to laboratory supplied bottleware and immediately placed on ice and maintained at a temperature of approximately 4°C. Groundwater samples were transported under standard chain -of -custody procedures to Shealy Environmental Services, Inc. of West Columbia, South Carolina. Groundwater samples were analyzed for benzene, ethylbenzene, toluene, xylenes (BTEX), by EPA Method 602. Monitoring wells MW-4, MW-6, MW-8, and MW-13 ware also analyzed for methyl tertiary -butyl ether (MTBE) by EPA method 602. Groundwater samples from three monitoring wells associated with the diesel fuel releases that occurred on March 13, 2015 and August 13, 2015 (MW-24, MW-25, and MW-25D) were also analyzed for semi -volatile organic compounds by EPA Method 625; and Massachusetts Department of Environmental Protection extractable petroleum hydrocarbons and volatile petroleum hydrocarbons. 4.0 GROUNDWATER FINDINGS 4.1 Well Gauging Results and Groundwater Flow Depth to water and top of well casing elevation data from the monitoring wells were used to calculate groundwater elevations relative to an on -site benchmark referenced to mean sea level datum. LNAPL was not detected in any of the groundwater monitoring wells or recovery wells gauged in August 2018. A summary of groundwater level measurements is provided in Table 2. A groundwater potentiometric map for the surficial unit using water level elevation data from the August 2018 sampling event is provided as Figure 4. The potentiometric map depicts the direction of groundwater flow to the southeast. A hydraulic gradient of approximately 0.03 feet per foot was measured between the 720 feet potentiometric contour line near MW-23 and the 705 feet potentiometric contour line near MW-8. Groundwater flow patterns observed in August 2018 are consistent with historic sampling events. LNAPL was not detected in any of the 12 recovery wells gauged during the August 16, 2018 sampling event. A summary of historic recovery well gauging data is provided as Table 3. APEX Semiannual Monitoring Report, March 2018-August 2018 October 1, 2018 Colonial Pipeline Company, Kannapolis Booster Station Page 5 4.2 Groundwater Analytical Results Groundwater sampling activities performed at the site focused on collecting analytical data from the upgradient, downgradient, and central plume areas to evaluate Constituents of Concern trends over time. The analytical results for groundwater samples collected during this monitoring period were compared to the 15A NCAC 2L .0202 Groundwater Quality Standards (21- Standards) and to the 15A NCAC 2B .0215 Surface Water Standards (2B Standards) for a Water Supply II, High Quality Waters surface water classification following the Risk Based Corrective Action Rules for non -UST releases of petroleum under North Carolina House Bill 765. A groundwater concentration map showing the concentration of benzene in the groundwater from the August 2018 event is provided as Figure S. Laboratory analytical reports and chain -of -custody records for the groundwater samples are presented in Appendix B. The August 2018 results indicate that the hydrocarbon plume is stable compared to the historic monitoring results. A summary of groundwater analytical results is provided in Table 4. Notable results from the August 2018 sampling event are summarized below: • Benzene was detected in MW-13 (5.2 micrograms per liter [pg/L]) and MW-24 (2.0 pg/L during the August 2018 sampling event. These concentrations exceeded both the 2L and 2B Standards of 1.0 pg/L and 1.19 pg/L, respectively. • MTBE was detected in MW-8 (6.6 pg/L) and MW-13 (2.5 pg/L) during the August 2018 sampling event. Concentrations were below the 2L and 2B Standards of 20 pg/L and 19 pg/L, respectively. • Ethylbenzene, toluene, total xylenes, acenaphthene, anthracene, fluoranthene, phenanthrene, and pyrene were detected in MW-24 and pyrene was detected in MW-25 during the August 2018 sampling event at concentrations below the 2L and 2B Standards. • Aliphatic and aromatic petroleum compounds were detected in MW-24 during the August 2018 sampling event. The detected concentrations observed included C9-C12 Aliphatics at 410 pg/L, C5-C8 Aliphatics at 740 pg/L, C9-C10 Aromatics at 330 pg/L, and C11-C22 Aromatics at 130 pg/L. C5-C8 Aliphatics and C9-C22 Aromatics exceeded NCAC 2L groundwater standards (400 pg/L and 200 pg/L respectively). C5-C8 Aliphatics and C9- I PEP Semiannual Monitoring Report, March 2018-August 2018 October 1, 2018 Colonial Pipeline Company, Kannapolis Booster Station Page 6 C12 Aromatics also exceeded protective values for surface waters at 125 pg/L and 180 pg/L respectively. 5.1 Air Sparge Trench Remediation System The air sparge trench remediation system was brought on-line in June 1998 to treat shallow groundwater prior to migration off -site. The air sparge system continues to operate to aid in the removal of benzene and MTBE from groundwater in the vicinity of well MW-8 and MW-13. It was shut down approximately two weeks prior to the August monitoring event to allow for collection of representative groundwater samples. 5.2 Bio-Sparge and Bio-Venting Systems The bio-sparge and bioventing systems were brought on-line on March 7, 2017 to address soil and groundwater impacts associated with the 2015 diesel fuel releases. The systems were shut down approximately two weeks prior to the August monitoring event to allow for collection of representative groundwater samples. 6.0 WATER SUPPLY WELL SAMPLING 6.1 Water Supply Well Sampling and Analysis Annual water supply well sampling was performed by CPC personnel in the site vicinity on August 23, 2018. Colonial voluntarily provides point -of -entry (POE) treatment systems (i.e., activated carbon vessels) at several water supply wells identified in Figure 6. Seven water supply wells were sampled during the August 22, 2017 sampling event. Samples were collected in laboratory supplied glassware, placed in an ice -filled cooler, and transferred to Prism Laboratories, Inc. of Charlotte, North Carolina under chain -of -custody procedures for analysis of BTEX, MTBE, and naphthalene. APEX Semiannual Monitoring Report, March 2018-August 2018 October 1, 2018 Colonial Pipeline Company, Kannapolis Booster Station Page 7 6.2 Water Supply Well Analytical Results Laboratory analytical results indicate that BTEX and naphthalene were not detected in the seven water supply wells at the influent of the POE systems. MTBE was detected in DW-Maurer-Influent at a concentration of 1.9 pg/L and in the DW-Tucker-Influent at a concentration of 1.3 pg/L which are below the 2L Standard of 20 pg/L. MTBE has historically been present in both of these wells. No other petroleum hydrocarbon constituents were detected in the water supply wells. A summary of historic and recent water supply well sampling analytical results is provided as Table 5. A copy of the laboratory analytical report and chain -of -custody records are included in Appendix B. 7.0 CONCLUSIONS AND RECOMMENDATIONS During the August 2018 monitoring event, residual LNAPL was not detected in recovery wells installed in response to the 2015 diesel fuel releases. Benzene, C5-C12 Aliphatics and C9-C22 Aromatics exhibited concentrations above the applicable 2B and/or 2L Standards in MW-24. This well is located approximately 360 feet from the surface water body. These detections are attributed to the 2015 diesel fuel releases. The recently installed bio-sparge and bioventing system will aid in the removal of these remaining hydrocarbon constituents from the subsurface. Monitoring wells MW-25 and MW-25D, located nearly 250 feet from the surface water body, continue to delineate the downgradient boundary of the plume in this area. Both monitoring wells were free of any detections during the August 2018 sampling event with the exception of a detection in MW-25 of pyrene at an estimated concentration of 0.51 pg/L, below the applicable 2L and 2B Standards. Benzene was detected in MW-13 during the August 2018 sampling event at concentrations greater than the 2L and 2B Standards. Detections of benzene at MW-13 are associated with the 1995 release as historic groundwater analytical data indicates the presence of benzene in this well since February 1998. Benzene concentrations in MW-13 have been decreasing over time, with seasonal fluctuations. Although the concentration during this monitoring event is greater than the three previous sampling events, the long-term trend is still downward. Although 2B Surface Water Standards were exceeded, any discharge of the groundwater plume to surface water would not likely contravene the surface water standards within the surface water body itself. APEX Semiannual Monitoring Report, March 2018-August 2018 October 1, 2018 Colonial Pipeline Company, Kannapolis Booster Station Page 8 During the August 2018 sampling event, MTBE was detected in MW-8 (6.6 pg/L) and MW-13 (2.5 pg/L). Concentrations were below the 2L and 2B Standards of 20 pg/L and 19 pg/L, respectively. The historic concentration trends of MTBE show a continual decrease in both MW-8 and MW-13. The air sparge system in the vicinity of wells MW-8 and MW-13 continues to operate and aid in the removal of benzene and MTBE from groundwater. Results of the water supply well sampling indicated an absence of petroleum hydrocarbon constituents in the water supply wells with the exception of MTBE which was detected in the Maurer well (DW-Maurer-Influent) and the Tucker Well (DW-Tucker-Influent) at concentrations below the 2L Standard of 20 pg/L. MTBE has been historically detected in both of these wells and both properties are served by POE systems. Colonial will continue to maintain the off -site POE water treatment systems and continue annual sampling of select water supply wells. Apex proposes that based on the absence of LNAPL detections during the reporting period, and the stable and/or decreasing dissolved phase petroleum concentration trends observed at the site since the historic and recent 2015 release incidents, the reporting schedule for the site be modified from semiannual to annual. Following NCDEQ approval, one annual report will be submitted on or before October 1st of each year detailing the semiannual monitoring well sampling and annual water supply well sampling results. The next semiannual groundwater sampling event is scheduled to occur in February 2019.

The following samples were affected: TH17080-005, TH17080-006, TH17080-007, TH17080-008. The samples were re -extracted with a passing Method blank. TH17080-005, TH17080-006, TH17080-008 all failed 1-Chloro-octadecane in both Run 1 and Run 2 due to matrix interference. Due to the need for fractionation of the samples Run 2 has been reported SVOCs by GC/MS The following samples were diluted due to the nature of the sample matrix: TH17080-005, TH17080-006, TH17080-008. The LOQ has been elevated to reflect the dilution.
