1.0 INTRODUCTION

This document presents a Remedial Action Progress Report (RAPR) for the period from July through December 2013 for the TransMontaigne – Selma North terminal in Selma, Johnston County, North Carolina. The site has been assigned Incident No. 90100 by the North Carolina Department of Environment and Natural Resources (NCDENR) due to of subsurface liquid-phase hydrocarbons (LPH) during routine site monitoring-well gauging in June 2012, and the subsequent detection of concentrations of petroleum chemicals of concern (COCs) in site soil and groundwater in August 2012, as described in the site Comprehensive Site Assessment Report (CSA report), dated September 12, 2012.

The plan for site soil/groundwater remediation was detailed in the Corrective Action Plan (CAP), dated December 10, 2012. NCDENR approval of the CAP was received via a January 16, 2013 letter from NCDENR to TransMontaigne. Installation of a soil vapor extraction (SVE) system was completed from March to April 2013 in accordance with the Technical Specifications: Soil Vapor Extraction System Installation, dated February 15, 2013, and startup of the SVE system occurred on May 16, 2013. Following is a summary of current information related to the site remediation system operation.

Summary of Remediation System Operation SVE system start-up date May 16, 2013 Reporting period July 1 – Dec. 31, 2013 SVE system ON-time during reporting period 1,656 hours SVE system OFF-time during reporting period 2,394 hours SVE system ON-time percentage during reporting period 41% Total SVE system ON-time since startup 492 hours Total SVE system ON-time percentage since May 2013 startup 42% Estimated mass of gasoline hydrocarbons recovered by SVE during reporting period 105 lbs Total estimated mass of gasoline hydrocarbons recovered by SVE since May 2013 startup 2,889 lbs Total volume of gasoline in liquid phase recovered from MW-1 since June 2012 16.7 gal

Site groundwater sampling was conducted during the reporting period in November 2013. Results of laboratory analysis indicate that groundwater COCs resulting from the gasoline release discovered in June 2012 remain confined to the immediate area of the release.

In order to enhance the rate of site groundwater remediation, air sparging is being added to the site remediation approach to complement the SVE system. Installation of an air-sparging well (AS-1) and air- sparging system was completed in January 2014. Startup of the air-sparging system occurred on January 27, 2014. Information regarding installation of the air sparging system will be reported in the next RAPR, covering the period from January through June 2014.

2.0 SITE BACKGROUND INFORMATION

2.1 Facility Information

The TransMontaigne-Selma North terminal is located at 2600 W. Oak Street in Selma, Johnston County, North Carolina. The facility location and layout are shown in Figures 1 and 2, respectively. The facility is a bulk-fuel storage and truck terminal containing five aboveground storage tanks (ASTs) that store gasoline (7101 and 7103), jet fuel (7105 and 7106), and ethanol (7104). The facility ASTs are located on the northeast side of the facility property and a truck loading rack is located on the southwest side of the facility property with an access drive from W. Oak Street. A product additive AST (7107) is located directly south of AST 7103, and two off-spec product ASTs (7108 and 7109) are located directly southwest of AST 7101. Product transfer piping from the ASTs to the loading rack is all aboveground. AST information is provided in Table 1.

The site is provided gasoline and jet fuel products from Colonial Pipeline Company via an underground pipeline that enters the facility property from the south side of W. Oak Street and connects to a pipeline manifold north of the terminal truck loading rack (Figure 2). Three additional underground pipelines run between the TransMontaigne-Selma North terminal and a separate TransMontaigne terminal across W. Oak Street (Selma South terminal). The pipelines are located near the Colonial Pipeline product line shown in Figure 2. One is used for receipt of ethanol from the Selma South terminal. The second is used to transfer jet fuel to the Selma South terminal. The third is used to transfer water (for fire suppression) to the Selma South terminal.

Construction of the terminal occurred in 1989. All ASTs except the off-spec product ASTs (7108 and 7109) were constructed in 1989. The off-spec product ASTs were constructed in 1992.

A vapor recovery unit (VRU) was formerly located south of AST 7103 and northeast of the truck loading rack (Figures 2 and 3). The VRU converted gasoline vapors recovered from facility AST and product transfer lines back into liquid gasoline and transferred the recovered product back into a site AST (7103). All inlet and outlet piping for the VRU was aboveground. The VRU was taken out of service and replaced with a flare unit located northwest of the terminal office around 2009-2010. The VRU was removed in early 2013 to make room for remediation system equipment (Section 3.0).

The Selma North terminal is located northwest of the town of Selma, North Carolina within an area occupied by several petroleum-fuel terminals owned and operated by various companies (Figure 4). The Selma North terminal property consists of approximately 17 acres of land. The operating portion of the

PIEDMONT GEOLOGIC, P.C. 5 Remedial Action Progress Report: July - December 2013 TransMontaigne – Selma North Terminal February 10, 2014

terminal occupies approximately 8 acres, and the remaining 9 acres are grass fields on the northwest and northeast sides of the terminal facility.

The natural topography of the terminal property is relatively flat, with less than 5-feet of overall topographic relief. The terminal fuel ASTs are located within a bermed, clay-lined and gravel-covered, containment basin. The truck loading rack, drive, and parking areas are paved with asphalt and concrete. A one-story concrete office building is located at the western corner of the terminal facility. No stormwater ponds or basins are located at the terminal property.

Nine monitoring wells are located at the terminal property. Locations of monitoring wells are shown in Figure 2 and well construction specifications are listed in Table 2. Monitoring-wells MW-1 through MW-5 and MW-7 through MW-9 are Type II, water-table, monitoring wells ranging in depth from approximately 15 to 20-feet below grade. Monitoring-well MW-6 is a deeper, vertical delineation, monitoring well completed to a depth of approximately 42-feet below grade. It is noted that monitoring-wells MW-1 through MW-5 were referred to as monitoring-wells “OW”-1 through “OW”-5 in site reports submitted prior to the September 2012 Comprehensive Site Assessment (CSA) Report and were renamed following installation of monitoring-wells MW-6 through MW-9 in August 2012.

2.2 Site Release Incident

One historical release of petroleum product is documented at the facility, which occurred during the early morning hours on January 18, 2008. The release was discovered by a facility operator who arrived at the facility at approximately 4:00 a.m. for a pipeline receipt and, upon routine inspection activity, discerned a gasoline odor near the facility VRU, located northeast of the terminal truck loading rack. Upon inspection, a crack was discovered in a 3/8-inch fitting on the VRU, through which gasoline product was observed to be spraying/dripping. The VRU was immediately shut down and the leaking fitting was isolated to stop the leak. The gasoline release was estimated to consist of approximately 40 gallons in an area encompassing approximately 10-feet by 15-feet on the east side of the VRU. A small “sump” was excavated in the release area for collection of the released gasoline, and all recovered gasoline and excavated soil were transferred to 55-gallon drums for subsequent management. Due to quasi-frozen ground conditions and high-clay content of the site soils, the depth of penetration of the released gasoline was believed to be minimal at the time of the release discovery.

NCDENR was notified of the release incident by telephone by a TransMontaigne manager at approximately 10:40 a.m. on January 18, 2008. Upon notification that no water sources were likely impacted by the release incident, no further actions or notifications were requested by NCDENR.

2.3 Description of June 7, 2012 Liquid-Phase Hydrocarbon Discovery

During routine monthly gauging of five site monitoring wells during the morning of June 7, 2012, LPH was detected in monitoring-well MW-1 at an apparent thickness of approximately 6 feet. The location of monitoring-well MW-1 is shown in Figure 2. MW-1 is a 2-inch inside diameter (I.D.) monitoring well that was installed in September 2011 along with four other monitoring wells (MW-2 through MW-5) for early release detection purposes and not in response to any known or suspected facility release. The five early release detection monitoring wells have been checked for the presence of LPH on a monthly basis since installation in September 2011. LPH was not detected in any wells prior to June 2012.

Petroleum product fingerprinting and age estimation indicated that the LPH discovered in MW-1 on June 7, 2012 was highly weathered regular grade gasoline, probably refined and released after 1994 but not recently. Based on this conclusion, the LPH is believed to be related to the gasoline release from the facility VRU that occurred on January 18, 2008, discussed in Section 2.2. Heavy rainfall, related to a tropical depression, occurred in the facility area in late May 2012, and it is conjectured that infiltration of this rainfall mobilized residual, and previously immobile, LPH from the 2008 release incident.

2.4 Site Geologic/Hydrogeologic Setting

The Selma North terminal is located in the Atlantic Coastal Plain physiographic province, near the border with the Piedmont physiographic province to the northwest. The Atlantic Coastal Plain is comprised of unconsolidated to semi-consolidated sediments, of Cretaceous to Quaternary age, that thicken toward the east from a featheredge boundary with the Piedmont province. According to the Geologic Map of North Carolina (North Carolina Geological Survey, 1985), the site is located on Tertiary terrace deposits and upland sediment, characterized by clayey sand and sand, gravel, with minor iron-oxide cemented sandstone.

Groundwater in the Tertiary terrace deposits in the Selma area occurs under unconfined (i.e., water table) conditions, and groundwater in the underlying Piedmont bedrock under both unconfined and confined conditions. Due to the typical limited areal extent and thickness, groundwater supplies and yields in the Selma area terrace deposits are limited. Groundwater in the overburden occurs within pore spaces of the unconsolidated medium. Any water-supply wells in the site area are probably completed in the underlying bedrock, in which groundwater occurs along zones of secondary permeability, such as fractures, bedding planes, foliations, solution voids, etc.

PIEDMONT GEOLOGIC, P.C. 7 Remedial Action Progress Report: July - December 2013 TransMontaigne – Selma North Terminal February 10, 2014

Site soils to the explored depth above bedrock at approximately 26-feet below grade consist of alternating layers of generally sandy clay and clayey sand. The observed lateral discontinuity of individual soil units is consistent with cut and fills operations completed during the terminal construction.

Bedrock was encountered at a depth of approximately 26-feet below grade in the boring for monitoring- well MW-6. The observed bedrock was greenish-gray schist, consistent with descriptions of Raleigh Belt metamorphic rocks situated along the Neuse River northwest of the site (North Carolina Geological Survey, 1985). Site geologic cross sections are presented in Figures 5 through 8.

Site monitoring-well gauging data are provided in Table 3. The site water table has been observed at depths ranging from approximately 2 to 13-feet below grade. Site water-table contour maps indicate a quasi-radial pattern of groundwater flow at the site, with apparent directions ranging from southerly in the southern part of the site to northeasterly in the northern part of the site. The water table gradient in the site release area (VRU area) is approximately 0.04 ft/ft. Based on relative groundwater elevations in adjacent shallow/deep monitoring wells MW-1 and MW-6 (Table 3), a downward groundwater potentiometric gradient exists in the site release area. Site groundwater-flow velocity is estimated to be approximately 71- feet per year (Piedmont Geologic, 2012a).

2.5 Site Soil and Groundwater COC Distribution

LPH has been detected in one site monitoring well (MW-1), located near the downgradient side of the former VRU. Results of laboratory analysis of August-October 2012 soil samples indicate that soil COCs at concentrations above MSCCs resulting from the gasoline release are limited to the vicinity of the VRU. Due to the relatively shallow depth to groundwater in the VRU area, soil contamination is confined to relatively shallow depths (≤6-feet below grade). Results of laboratory analysis of August 2012 groundwater samples indicate that groundwater COC concentrations above 2L standards resulting from the VRU release are also limited to the vicinity of the VRU. Vertical delineation of site groundwater contamination is established through results of groundwater sampling for site deep-monitoring-well MW-6. No on-site or off-site receptors have been identified that would appear to be at risk due to the delineated soil and groundwater contamination at the site.

Maximum detected concentrations of site soil and groundwater COCs are summarized as follows, along with applicable NCDENR cleanup levels. For site soils, the applicable NCDENR cleanup levels are the Soil-to-Groundwater MSCCs. For groundwater, the applicable NCDENR cleanup levels are the North

PIEDMONT GEOLOGIC, P.C. 8 Remedial Action Progress Report: July - December 2013 TransMontaigne – Selma North Terminal February 10, 2014

Carolina 2L standards. In addition, it is required that LPH thicknesses in site monitoring wells be reduced to non-detectable levels (i.e., <0.01 feet of thickness).

The Intermediate risk ranking established by NCDENR was based on the presence of LPH in site monitoring-well MW-1. With mitigation of LPH in MW-1, the site should be eligible for a reduction in risk ranking to Low, since no other site factors are such that would trigger an Intermediate (or High) risk ranking.

2.6 Summary of LPH Characterization and Recovery

Summaries of LPH gauging and recovery are provided in Tables 3 and 4. LPH has been detected only in monitoring-well MW-1. The greatest observed thickness of LPH in MW-1 was approximately 6 feet on June 7, 2012, at the time of discovery. Manual LPH bailing from MW-1 was conducted from June 7-14, 2012. A passive LPH skimmer was installed in MW-1 on June 14, 2012. Following installation the passive skimmer was checked and emptied of LPH on a daily to weekly basis from June to October 2012, and then on a weekly basis from October 2012 to May 2013. A total of approximately 16.7 gallons of LPH was recovered from MW-1 through this process (Table 4). Most (87%) of this volume was recovered on June 7, 2012, the day of the LPH discovery in MW-1.

A graph of groundwater and LPH levels in MW-1 from June 2012 to November 2013 is provided as follows.

Following installation of the passive LPH skimmer in June 2012, detected LPH thicknesses ranged from 0.01 to 0.61 feet during June 2012, and from 0.01 to 0.08 feet during July through most of November 2012. LPH was not detected in MW-1 on several gauging dates (Table 3) from July to November 2012, but then was detected at apparent thicknesses of 1.62 to 2.27 feet in late November 2012. As shown in the graph above, the increase in apparent LPH thickness in late November 2012 corresponded with a decline in the site water-table level, to the lowest point observed over the time period. Following January 2013, LPH has only been detected in MW-1 on two gauging dates (August and September 2013), at apparent thicknesses of 0.01 feet.

3.0 SVE SYSTEM DESCRIPTION

A map showing the generalized layout of the site SVE remediation system is provided as Figure 9. The SVE system was designed based on the results of November 2012 pilot testing, which indicated a conservative radius of SVE influence of approximately 30 feet, as described in the December 2012 CAP (Piedmont Geologic, 2012b).

The remediation system incorporates four SVE wells. SVE transfer lines are plumbed through subsurface piping trenches to an equipment building, which contains the system vacuum blower, moisture separator, control panel, and programmable controller/telemetry system. A summary of remediation system equipment is provided as follows.

SVE System Equipment Summary System Component No. Units Brand, Model, Rating Soil vacuum extraction blower 1 M-D Pneumatics model 5009 vacuum pump; 25 hp, 480-volt, three-phase, XP-motor; rated for 500 scfm at 10 in. Hg. Control panel 1 NEMA Class 4, externally mounted; motor starters with thermal overloads. Telemetry 1 EOS ProView Series II programmable controller. Building enclosure 1 10 ft x 20 ft pre-fabricated building.

The system telemetry system allows for remote monitoring and startup/shutdown capabilities for individual system components. The telemetry system also provides a daily report showing system operational status, including SVE effluent airflow readings.

4.0 SVE SYSTEM OPERATION, MONITORING, AND PERFORMANCE

SVE operation and monitoring forms for the reporting period are provided in Appendix B. The SVE system was on for a total of approximately 1,656 hours and was off for a total of approximately 2,394 hours during the reporting period, for a total on-time percentage of approximately 41%. SVE system downtime during the reporting period was primarily due to a retrofit of the system telemetry in the 3rd quarter of 2013, to allow for remote access and monitoring of the system. Additional down time during the reporting period was the result of high-water-level conditions in the SVE moisture-separator tank, which occurred due to high water-table conditions and resulted in system shutdowns pending manual emptying of the tank. Water removed from the moisture-separator tank was transferred to the facility petroleum contact water (PCW) tank for appropriate offsite treatment/disposal.

SVE-system effluent-air samples were collected for laboratory analysis on July 26, 2013 and November 13, 2013. The SVE effluent-air samples were submitted under chain-of-custody to Environmental Science Corp. in Mt. Juliet, Tennessee (ESC) and analyzed for benzene, toluene, ethylbenzene, xylenes (BTEX), methyl tert-butyl ether (MTBE), and gasoline range organics (GRO) by EPA Method 18-modified.

An estimated total of approximately 3.3 x 107 cubic feet of soil vapor was recovered during the reporting period. The overall mean soil vapor recovery rate through SVE was approximately 337 standard cubic feet per minute (scfm) at a mean applied vacuum of approximately 3.8 inches of mercury (in. Hg).

Results of laboratory analysis of SVE effluent-air samples collected since system startup in May 2013 are summarized as follows.

5.0 GROUNDWATER SAMPLING AND ANALYSIS

5.1 Groundwater Sampling and Analysis Methods

Site groundwater sampling was conducted at the site on November 13, 2013. The November 2013 sampling event included site monitoring wells MW-1, MW-3, MW-7, MW-8, and MW-9. Prior to initiation of sampling, groundwater levels were measured in all site monitoring wells using an electronic interface probe, which distinguishes between groundwater and LPH. LPH was not detected in any site wells.

Monitoring wells were sampled using the standard purge/sample method described as follows.

 The well was purged of three standing volumes of groundwater, or until dry, using either a submersible pump with dedicated, disposable nylon tubing or a dedicated, bottom-loading, disposable polyethylene bailer and nylon rope;  Following removal of each standing volume of groundwater, field measurements of purge-water pH, temperature, dissolved oxygen (DO), and specific conductance were collected;  Within 24 hours following purging, a groundwater sample was collected using a bottom-loading disposable bailer and nylon rope, transferred to labeled, laboratory-prepared sample bottles, and placed on ice in a cooler.

Groundwater samples were placed immediately in a cooler on ice upon collection, sent under chain of custody ESC, and analyzed for volatile organic compounds by EPA Method 8260.

5.2 Groundwater Sampling and Analysis Results

Site groundwater level data are provided in Table 3. A site water-table contour map based on November 13, 2013 groundwater gauging results is provided as Figure 10.

Results of laboratory analysis of November 2013 groundwater samples are summarized in Table 5 and Figure 11. A historical summary of site groundwater analysis results is provided in Table 6.

The following COCs were detected in the November 2013 groundwater sample from monitoring-well MW- 1 at concentrations above North Carolina groundwater standards under 15A NCAC 2L .0202.

PIEDMONT GEOLOGIC, P.C. 15 Remedial Action Progress Report: July - December 2013 TransMontaigne – Selma North Terminal February 10, 2014

 Benzene;  n-Butylbenzene;  Ethylbenzene;  Isopropylbenzene;  Methylene chloride;  Naphthalene;  n-Propylbenzene;  Toluene;  1,2,4-Trimethylbenzene;  1,3,5-Trimethylbenzene; and  Xylenes.

Methyl tert-butyl ether was detected at a concentration above the North Carolina 2L standard of 20 ug/L in the groundwater sample from MW-8. The results of November 2013 groundwater sampling/analysis indicate that groundwater COCs resulting from the gasoline release discovered in June 2012 remain confined to the immediate area of the release.

6.0 RECOMMENDATIONS

With subsurface LPH being apparently mitigated at the site, air sparging is being added to the site remediation approach to complement the SVE system and enhance the rate of site groundwater remediation. Installation of an air-sparging well (AS-1) and air-sparging system was completed in January 2014. Startup of the air-sparging system occurred on January 27, 2014. Information regarding installation of the air sparging system will be reported in the next RAPR, covering the period from January through June 2014.

The data package includes a summary of the analytic results of the quality control samples required by the SW-846 or CWA methods. The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report.

Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier.

Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples.

Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.
