The site is approximately 17.25 acres in area and contains an approximate 29,400 square ft office and warehouse building and an approximate 10,900 square ft former service garage building. Currently, the site is used as a trucking terminal and is located in a mixed commercial, industrial and residential area of Hickory, North Carolina. Monitoring wells TMW-1, MW-2, and MW-3 were sampled on June March 22, 2023. In addition, slug testing was conducted in monitoring wells MW-2 and MW-3. Laboratory analytical results indicate that naphthalene, 1-methylnaphthalene, and 2-methylnaphthalene were detected above the NC 15A NCAC 02L.0202 Groundwater Standards (2L Standards) in TMW-1. No compound concentrations exceeded their DEQ-defined GCLs in TMW-1. Additionally, no compound concentrations were detected above the groundwater standards in the remaining monitoring wells. Conservative groundwater fate and transport modeling indicates naphthalene concentrations equal to or above the 2L Standard will extend to a maximum distance of approximately 49 ft from the source area, and naphthalene concentrations above the laboratory detection limits will extend to a maximum distance of approximately 81 ft from the source area. Additionally, a GSI Mann-Kendall statistical analysis indicates naphthalene concentrations in the source area are currently stable, and the estimated time required to reach the naphthalene 2L Standard in source area monitoring well TMW-1 is approximately 51.5 years (from the year 2017) based on a linear regression analysis. 2 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc Based on the result of the groundwater sampling, groundwater fate and transport modeling, and plume stability evaluation, naphthalene should not be detected above the laboratory detection limit or its 2L Standard at the unnamed tributary of Henry Fork River located approximately 300 ft downgradient of the source area, and the threat of impacts to on-site and off-site water supply wells appears to be low. As a result, H&H recommends that the risk ranking for the site be reduced to low risk and that DEQ issue no further action (NFA) for the UST release. 3 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc 2.0 Site History and Source Characterization On behalf of Dietz Holding, LLC, Hart & Hickman, PC (H&H) has completed this Monitoring Report for the former Dietz trucking terminal located at 8814 Dietz Avenue in Hickory, Burke County, North Carolina. The site is approximately 17.25 acres in area and contains an approximate 29,400 square ft office and warehouse building and an approximate 10,900 square ft former service garage building. Currently, the site is used as a trucking terminal and is located in a mixed commercial, industrial and residential area of Hickory, North Carolina. A site location map is presented as Figure 1, and a site layout is depicted on Figure 2. Underground storage tank (UST) closure activities were conducted at the site for a 10,000-gallon diesel UST on July 20 and 21, 2010. During UST closure, approximately 112 tons of impacted soils were excavated from around the UST and transported off-site for proper disposal. The UST excavation was limited in extent on its western sidewall due to the existence of the former service garage building. The results of analyses of the post-excavation soil samples indicated that one sample (labeled West SW) in the excavation western sidewall contained compound concentrations above soil-to- groundwater Maximum Soil Contaminant Concentrations (MSCCs). No post-excavation soil sample concentrations exceeded residential or commercial/industrial MSCCs. Based on soil remaining in the excavation western sidewall above the lowest MSCCs, H&H recommended that a Phase I Limited Site Assessment (LSA) be completed for the site in accordance with North Carolina Department of Environmental Quality (DEQ) guidance. Additionally, due to the close proximity of the on-site water supply well, H&H also recommended sampling the well during the Phase I LSA. In a Notice of Regulatory Requirements (NORR) letter dated August 26, 2010, DEQ indicated that a Phase I LSA should be completed for the site. On October 27, 2010, H&H oversaw the advancement of LSA monitoring well TMW-1 adjacent to former soil sample West SW that contained the highest compound concentrations during the 4 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc initial abatement activities. Soil samples were not collected from the TMW-1 boring because the initial abatement excavation extended to the water table and excavation sidewall samples for risk-based analysis were collected as part of the initial abatement. In addition, on-site water supply well WSW-1 also was sampled. Because the groundwater analytical results for TMW-1 indicated compound concentrations greater than 10 times the groundwater standards, and because water supply wells were identified within 1,000 ft, H&H conducted additional assessment activities to meet the requirements of a Phase II LSA. On December 20, 2010, H&H oversaw the installation of monitoring wells MW-2 and MW-3 in locations anticipated to be downgradient of the former UST basin and MW-4 in a location anticipated to be upgradient of the former UST basin. The results of the Phase I and II LSA groundwater analyses indicated that C9-C18 aromatics, total C9-C22 aromatics, naphthalene, and 2-methylnaphthalene were detected above the North Carolina groundwater standards in TMW-1. Free product was not identified, and no compound concentrations exceeded their DEQ-defined Gross Contamination Levels (GCLs). No compound concentrations were detected above laboratory detection limits in monitoring wells MW-2 through MW-4 and water supply well WSW-1. Because water supply wells are located within 1,000 ft of the site, post-excavation confirmation soil sample concentrations exceed soil-to-groundwater MSCCs, and petroleum compounds exceed the North Carolina groundwater standards, H&H recommended that a Comprehensive Site Assessment (CSA) be completed for the site in accordance with DEQ guidance. In a letter dated February 8, 2011, DEQ requested that a CSA be completed in accordance with applicable guidelines. In subsequent phone calls between H&H and DEQ, DEQ approved limited CSA activities based on the lack of significant soil and groundwater impacts at the site. Limited CSA activities were conducted in August and September 2011. The activities included installation of one deep monitoring well, sampling five groundwater monitoring wells, and sampling the two closest downgradient water supply wells to the source area. Target compound concentrations in groundwater samples were detected above the North Carolina groundwater 5 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc standards in shallow source area monitoring well TMW-1 only. No concentrations exceed GCLs and no free product was detected in any of the monitoring wells. Additionally, no target compounds were detected above laboratory detection limits in the two closest downgradient water supply wells to the source area. Based on the results of the limited CSA activities conducted by H&H, DEQ issued an NORR letter dated December 5, 2011 requesting a Corrective Action Plan (CAP) be completed for the site. H&H prepared a Natural Attenuation CAP dated August 10, 2012, which identified natural attenuation as the most cost-effective means to remediate petroleum-impacted soil and groundwater at the former Dietz Trucking Terminal site. The CAP was approved by DEQ in an NORR letter dated August 20, 2012. 6 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc 3.0 Summary of Potential Receptor Information 3.1 Water Supply Wells H&H conducted a water supply well survey for the area within a 1,500-ft radius of the former UST basin during the Phase I and II LSA and updated during the limited CSA activities, as necessary. The survey was conducted by performing area reconnaissance and checking for municipal water connections. H&H also conducted an extended survey of properties within 500 ft of the UST area, which included contacts with knowledgeable personnel at those adjacent properties with structures present. The results of the survey indicated that city water is available to properties within a 1,500-foot radius of the site. Eleven water supply wells were identified at or within 1,000 ft of the source area. Of these, eight are utilized for drinking water and three are not used. The approximate water supply well locations are depicted on Figure 3, and supply well owner information and well specifics are presented in Table 1. 3.2 Surface Water The closest surface water body is an unnamed intermittent stream located approximately 300 ft southwest of the source area (Figures 1 and 3). Henry Fork River is located approximately 2,500 ft south of the source area. Henry Fork River is designated as a “Class C” surface water body in the vicinity of the site. 7 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc 4.0 Groundwater Monitoring 4.1 Water Levels On June 6, 2023, the depths to groundwater were measured in monitoring wells TMW-1, MW-2, MW-3, and MW-4 (Table 2). Depths to groundwater at the site were approximately 11 to 14 ft below ground surface. No free product was detected in the monitoring wells during gauging. Calculated groundwater elevations are presented on Figure 4. Based on these data, the estimated shallow groundwater flow is to the southwest at the subject property. 4.2 Monitoring Well Analytical Data On June 6, 2023, groundwater samples were collected from monitoring wells TMW-1, MW-2, MW-3, and MW-4. Prior to sampling, the wells were purged until pH, temperature, and conductivity stabilized. Groundwater samples were then collected using dedicated polyethylene bailers, poured in laboratory supplied containers marked with identifying labels, and placed in an iced cooler for shipment under chain-of-custody protocol to a certified laboratory for analyses. The groundwater samples were analyzed for volatile organic compounds (VOCs) by EPA Method 6200B and semi-VOCs by EPA Method 625. The chain-of-custody records and laboratory analytical data sheets are provided in Appendix A. As shown in Table 3, naphthalene, 1-methylnaphthalene, and 2-methylnaphthalene were detected above the groundwater standards in TMW-1. No compound concentrations exceeded their DEQ- defined GCLs in TMW-1. Additionally, no compound concentrations were detected above the groundwater standards in the remaining monitoring wells. 8 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc 5.0 Groundwater Modeling Evaluation As previously discussed, the DEQ approved CAP identified natural attenuation as the most cost- effective means to remediate petroleum-impacted soil and groundwater at the former Dietz Trucking Terminal site. To expedite site closure, H&H conducted conservative screening level groundwater modeling and a plume stability analysis to evaluate groundwater plume migration and the potential for future water supply well impact from the diesel related compound naphthalene. Please note that 1-methylnaphthalene and 2-methylnaphthalene also currently exceed the groundwater standards in source area well TMW-1. These compounds were not modeled because they are anticipated to degrade and migrate in groundwater similarly to naphthalene, and as such, are unlikely to impact downgradient potential receptors. 5.1 Slug Testing As part of the fate and transport modeling, slug tests were performed on monitoring wells MW-2 and MW-3 during the June 2023 groundwater sampling activities to calculate site-specific hydrogeologic data. A slug of water was removed from the wells using an 83-inch long disposable bailer and the water level recovery in the wells was monitored over time. The slug test data were analyzed using the method of Bouwer and Rice. The slug test results are summarized in Table 4, and the slug test data are included in Appendix B. The slug data indicate that the hydraulic conductivity at the site ranged from 0.96 ft/day to 1.23 ft/day with a geometric mean of 1.11 ft/day in the shallow monitoring wells. Based on the shallow hydraulic gradient of 0.03 ft/ft, hydraulic conductivity geometric mean of 1.11 ft/day, and assumed effective porosity of 0.2, the calculated shallow groundwater velocity is approximately 65 ft/yr. 5.2 Groundwater Fate and Transport Modeling To evaluate the downgradient extent of naphthalene in groundwater and to predict future plume migration, H&H conducted groundwater contaminant transport modeling using BIOSCREEN, 9 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc Version 1.4 software (see EPA publication EPA/600/R-96/087, August 1996). This model is based on the Domenico analytical solution to groundwater transport which considers chemical advection, dispersion, adsorption, biodegradation, and saturated zone source area mass. Model Calibration Based on the site groundwater flow direction to the southwest towards an unnamed tributary of Henry Fork River, the model was developed and calibrated using naphthalene concentrations from source area well TMW-1 through downgradient well MW-2. The geometric mean of hydraulic conductivities from the slug tests, a hydraulic gradient of 0.03 ft/ft based on June 2023 gauging data, an average effective porosity of 0.2, and the average seepage velocity calculated for the site from the slug test data of approximately 65 ft/yr were utilized in the model. Other model input parameters and their derivations are included: • longitudinal and transverse dispersivities of 6.5 ft and 0.2 ft , respectively (model calibrated values); • bulk density of 1.5 kg/L (typical value for saprolite); • fraction organic carbon value of 0.0001 (based on typical default value and model calibration); • retardation factors of 1.7 (based on model calibration); • estimated first order degradation rates based on model calibrations of 3.5/yr; • 15 ft wide and 10 ft thick source term dimensions (based on source area and model calibrations); and, • Initial source area masses of approximately 0.2 kilograms (Kg) (based on model calibration). Using the parameters listed above and using source area soil and groundwater concentrations from 2010 (when the UST was removed), the model was calibrated to provide the contaminant distribution along the plume centerline and transverse of the plume centerline in 2023 (or 13 years since 2010). A summary of the model calibration is provided in Table 5, and the model calibration output sheets are provided in Appendix C. 10 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc As shown in Table 5, the model calculated TMW-1 and MW-2 naphthalene concentrations generally matched the actual concentrations. Based on the overall good model agreement with groundwater concentrations, the model is considered well-calibrated for the intended purpose. Predictive Modeling Results Following calibration, H&H modeled naphthalene transport to predict the future concentrations and extents of this compound in groundwater. The results of the future predictive modeling indicate that groundwater impacts and extents will decrease with time and that naphthalene concentrations equal to or above the 2L Standard will extend to a maximum distance of approximately 49 ft from the source area, and naphthalene concentrations above the laboratory detection limits will extend to a maximum distance of approximately 81 ft from the source area. As such, naphthalene should not be detected above the laboratory detection limit or its 2L Standard at the unnamed tributary of Henry Fork River located approximately 300 ft downgradient of the source area. Additionally, by a time of 5 years from the present (the year 2018), the model predicts that the naphthalene groundwater plume edge has begun to shrink back towards the source area. The predictive modeling results are provided in Appendix C and summarized in Table 5. 5.3 Naphthalene Plume Stability and Degradation Rate Constant Evaluation H&H conducted an evaluation of plume stability and fate for groundwater source area impacts at the site. The evaluation included performing a Mann-Kendall statistical analysis and calculating a degradation rate constant (kpoint) for naphthalene groundwater concentrations in source area well TMW-1. The GSI Mann-Kendall Toolkit spreadsheet and a plot of the naphthalene concentrations vs time with a linear regression analysis are included in Appendix D. Because of slight differences in concentrations, the Mann-Kendall analysis was performed using both the EPA Method 602/6200B and EPA Method 625 naphthalene data from source area well TMW-1. As indicated in Appendix D, the results of the Mann-Kendall analysis indicate that the naphthalene concentration trends in source area well TMW-1 are either stable or “No Trend”. 11 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc The GSI Mann-Kendall Toolkit User’s Manual (November 2012) indicates the following with regard to a “No Trend” finding: “A statistical result of “No Trend” indicates that the concentration cannot be determined to be either increasing or decreasing over time with sufficient statistical confidence. This outcome differs from “Stable,” which also indicates neither an increasing nor a decreasing trend, but with less variability in concentrations from one sampling episode to the next. However, in practical terms, if the purpose of the Mann-Kendall analysis is to determine whether the plume is increasing, stable, or decreasing over time, a “No Trend” result can be considered as evidence that the plume concentration is not increasing at the relevant sampling point, similar to a “Stable” result.” As such, the plume stability analysis indicates that the naphthalene concentrations in the source area are currently stable. To further evaluate the stability and fate of the groundwater naphthalene impacts, a linear regression analysis was conducted to determine the slope of a “best-fit” line to historical naphthalene concentrations in TMW-1 to predict when naphthalene concentrations in the source area may achieve the groundwater standard of 6 ug/L. Because the Mann-Kendall analysis of historical naphthalene data indicated the source area plume is currently stable, only data from the last two sampling events (2017 and 2023) were utilized in the linear regression analysis in order to evaluate more recent site conditions (last 6 years). Based on the linear regression, the kpoint for TMW-1 is approximately 0.081 per year. The y-intercept is calculated to be approximately 390 µg/L. The time to reach the 2L Standard was calculated with the following formula: Time (years since 2017) = -Ln (6 ug/L (2L goal) / y-intercept) / kpoint. By entering kpoint and y-intercept values into the formula, the estimated time to reach the 2L Standard under current site conditions (from the year 2017) in TMW-1 is calculated to be approximately 51.5 years (or the year 2069). 12 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc 6.0 Conclusions, Recommendations, and Certification Groundwater sampling activities were conducted in June 2023 at the former Dietz trucking terminal. The activities included sampling three groundwater monitoring wells TMW-1, MW-2, MW-3, and MW-4, and conducting slug testing in monitoring wells MW-2 and MW-3. Conservative fate and transport modeling was conducted using the results of current and historical groundwater concentration results and hydrogeologic data calculated from slug test data. The sampling and modeling results indicate the following: • Petroleum compounds were detected above the North Carolina groundwater standards in monitoring well TMW-1. No concentrations exceed GCLs and no free product was detected in any of the monitoring wells. The horizontal and vertical extent of groundwater impacts above standards is well defined and is limited to a small area in the area of the former diesel UST. • Conservative groundwater fate and transport modeling indicates naphthalene concentrations equal to or above the 2L Standard will extend to a maximum distance of approximately 49 ft from the source area, and naphthalene concentrations above the laboratory detection limits will extend to a maximum distance of approximately 81 ft from the source area. • A GSI Mann-Kendall statistical analysis indicates naphthalene concentrations in the source area are currently stable, and the estimated time required to reach the naphthalene 2L Standard in source area monitoring well TMW-1 is approximately 51.5 years (from the year 2017) based on a linear regression analysis. Based on the result of the groundwater sampling, groundwater fate and transport modeling, and plume stability evaluation, naphthalene should not be detected above the laboratory detection limit or its 2L Standard at the unnamed tributary of Henry Fork River located approximately 300 ft downgradient of the source area, and the threat of impacts to on-site and off-site water supply 13 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/Dietz Trucking (ROS-001)/Sampling/0623/Monitoring Report.doc wells appears to be low. As a result, H&H recommends that the risk ranking for the site be reduced to low risk and that DEQ issue an NFA for the UST release. Certification: 1.
