Defense Fuel Supply Point Charleston, SC

DFSP Charleston Terminal

SECTION 1.0 INTRODUCTION

Defense Fuel Support Point (DFSP) Charleston Terminal occupies approximately 44 acres in

Hanahan, SC and includes seven 80,000-barrel aboveground storage tanks (ASTs). The facility also includes a Truck Rack Area where tanker trucks are loaded for fuel distribution, the Rail Car Area where fuel is transferred to rail cars, an office building, a fuels laboratory, bottle room at the fuels laboratory, a pump station, various piping for fuel distribution, and a common oil/water separator

(OWS) for the facility. The facility, identified as the Fuel Terminal, is an active fuel terminal supplying military customers in the city of Charleston and surrounding areas with jet propellant

(JP)-5 and JP-8.

1.1 Environmental History:

Groundwater contamination within and around the DFSP originates from known and suspected releases of petroleum hydrocarbons. A known release occurred around Tank 1 in 1975 when 84,000 gallons of jet fuel were leaked. Other releases are suspected in the vicinity of Tank 3, the Truck

Rack, and the Fuels Laboratory, based on detections of benzene, toluene, ethylbenzene, xylenes

(BTEX), methyl tertiary butyl ether (MTBE), and naphthalene in groundwater and soils. At the pump station, which is adjacent to the rail yard on the eastern side of the facility, other volatile organic compounds (VOC) including cyclohexane, 2-hexanone, 4-methyl-2-pentanone, and methyl-cyclohexane were detected in groundwater samples. The source has not been determined.

1980 – Several environmental investigations have been conducted since the discovery of groundwater contamination, with a complete summary of the early investigation and remediation activities are available from the USGS. A groundwater sampling program was established and has been ongoing since 1990 with quarterly samples collected since 1992.

July 2009 - A slurry of Oxygen Releasing Compound-Advanced™ (ORC-A) was injected into 11 site wells to enhance oxygen levels in the aquifer, stimulate aerobic biodegradation, and decrease naphthalene concentrations in the groundwater.

2012 – Free product thickness levels ranged from 0.01 to 2.24 feet (ft), but were typically less than one foot. Dissolved benzene and naphthalene concentrations continued to exceed site-specific cleanup goals (CGs). At this time, naphthalene is the most prevalent compound found at the DFSP.

DLA has requested that the DPE system be shut down as recent data indicates that it is no longer effective in removing source contamination; however, SCDHEC maintained that the system must remain in operation until all off-site contamination has been addressed.

November 2014 – Eighty-five direct push technology (DPT) sampling points were installed via DPT rig or hand auger to continue a site characterization that began in May/June 2012. Of the 59 soil samples collected, 12 had exceedances of 10 analytes including naphthalene, ethylbenzene, toluene, benzo(b)flouranthene, benzo(k)flouranthene, chrysene, dibenzo(a,h)anthracene, m-, p-, and o-xylenes. Of the 82 groundwater samples collected, 15 had exceedances of 6 VOCs including naphthalene, benzene, 1,2-dichloroethane, benzo(a)pyrene, methylene chloride, and penta-chlorophenol. While there were detections of other VOCs and SVOCs in soil and groundwater, no other compounds were detected at concentrations exceeding regulatory criteria.

January 2015 –Sulfate Enhanced Bioremediation (SEB) was used to target select areas of the site. A sulfate substrate (EAS provided by EOS Remediation, LCC) was injected into the subsurface via temporary injection points to deliver sulfate to the indigenous microbial population in order to enhance the biological degradation of the site contaminants. Three extraction wells in the vicinity of the injection activities were idled prior to injection to prevent removal of the substrate. The injection points were installed by a Geoprobe™ 7822 DPT rig. After the SEB amendments were injected into the subsurface, each well was permanently abandoned by a driller licensed in the State of South

Carolina in accordance with South Carolina Well Standards and Regulations R-61.71.

Calendar Year 2015 – Corrective Actions performed included the operation of: Tank 1 SVE system, Tank 3 SVE system, Truck Rack SVE system, groundwater extraction wells, and GWTP.

Activities also included quarterly groundwater and monthly GWTP influent and effluent monitoring.

During the quarterly groundwater monitoring events, samples were analyzed for BTEX, naphthalene, and MTBE. Only benzene and naphthalene were detected above their CGs in 2015. The majority of concentrations detected in excess of their CGs were identified at off-site properties to the north and west of the DFSP.

Surface water samples were also collected from SW-1, which were also analyzed for BTEX, naphthalene, and MTBE. Concentrations for these COCs were not detected at, or in excess of, the respective laboratory method detection limits in the SW-1 samples.

Free product was not detected during any of the gauging events. The geochemical evaluation indicated that in areas where fuel compounds are present, the aquifer is under anaerobic conditions.

Overall, evidence suggests that microbial degradation has occurred in the past and is likely continuing. However, the rate of degradation was unable to be determined.

February 2016 – January 2017 – Long response actions (LTRA) were performed at the site, which included the 13 groundwater extraction wells, three independent SVE systems, GWTP, and associated infiltration gallery. During this reporting period, the following activities were performed:

• Replacement of the three-independent SVE systems

• Retrofitting and repairs to the GWTP

• Operation and maintenance (O&M) of the remedial systems

• Performance of quarterly groundwater monitoring events

• Implementation of three biological injection events to target on-site hydrocarbon mass proximal to the Tank 1, Tank 3 and Truck Rack Areas.

During the operational period, the groundwater treatment plant recovered, treated, and discharged approximately 2,433,230 gallons of groundwater. As a result of the biological injection program, the

SVE systems were operated at limited capacity during the operating period, and therefore, measurable vapor-phase recovery was not monitored or measured during that time. Additional monitoring of the biological injection program was performed to determine the overall effectiveness of the program.

Monthly groundwater gauging events at the site have not identified free-phase petroleum since

August 2014. Results of the quarterly groundwater sampling program indicate that CGs for all constituents have been reached, with the exception of benzene and naphthalene. Benzene and naphthalene CGs have been met at all locations sampled with the exception of two on-site and six off-site locations. It was noted that the remedial system mass recovery rates are limited and system operation will not address off-site contamination to the west and north of the site. It was recommended to discontinue monthly free product gauging events and deactivation of the groundwater extraction and soil vapor extraction remedial systems for one quarter (three months) to evaluate for potential rebound of dissolved-phase contaminant levels.

Charleston Fuel Pipeline Facility

SECTION 1.0 INTRODUCTION

Joint Base Charleston is a United States military facility located partly in the City of North

Charleston, South Carolina and partly in the City of Goose Creek, South Carolina. The facility is under the jurisdiction of the United States Air Force 628th Air Base Wing, Air Mobility Command

(AMC).[2]

The facility is an amalgamation of the United States Air Force Charleston Air Force Base and the

United States Navy Naval Support Activity Charleston, which were merged on 1 October 2010. A joint civil-military airport, JB Charleston shares runways with Charleston International Airport for commercial airlines operations on the south side of the airfield and general aviation aircraft operations on the east side.

1.1 Environmental History:

Defense Fuel Support Point (DFSP) Charleston is located at 5862 North Rhett Extension, Hanahan, SC. The DFSP terminal is an active fuel terminal supplying military customers in Charleston and surrounding areas with jet propellant (JP)-5 and JP-8. An eight-inch diameter underground pipeline is used to transport fuel from DFSP Charleston to Charleston Air Force Base (AFB). A leak was detected along this pipeline in 1993 in the airfield adjacent to South Aviation Road on the south side of the AFB. Approximately 500 gallons of JP-4 and 500 gallons of hydrocarbon-impacted groundwater were removed from the site using a vacuum truck immediately following discovery of the leak.

December 1993 – A leak was detected in the pipeline in the airfield adjacent to Perimeter Road that transports fuel from DFSP Charleston to Charleston Air Force Base (CAFB). Jet fuel was released to the environment before the leak was discovered and repaired. Initial response activities removed approximately 500 gallons of JP-4 and 500 gallons of hydrocarbon-impacted groundwater using a vacuum truck. The leak resulted in subsurface contamination consisting of a small area of free product (residual jet fuel) surrounded by a larger plume of dissolved fuel constituents. Since

September 1995, quarterly sampling of groundwater and surface water has been ongoing to determine the extent of contamination.

October 1994 to July 2000 – An interim free product recovery system recovered approximately

15,000 gallons of free product. This recovery system was shut down in July 2000 due to high water levels and electrical problems. February 2002 – A revised Corrective Action Plan (CAP) was prepared recommending dual-phase (soil vapor and water) extraction with on-site treatment of extracted groundwater and soil vapor as the preferred corrective action. Site-specific cleanup goals were approved by SCDHEC in July 2003. However, planned activities, including the installation of additional upgradient groundwater monitoring wells, were deferred pending completion of remediation construction activities for the Pipeline site. Free product and impacted groundwater pump-out activities were also suspended at the site.

March 2011 – A treatment system was constructed and the groundwater and soil vapor extraction

(SVE) system began operation. The remediation system at the Pipeline Site includes 20 dual-phase recovery wells, on-site treatment for extracted vapors, on-site treatment for extracted groundwater, various pipe runs and wiring, and a permitted National Pollutant Discharge Elimination System

(NPDES) outfall. The recovery wells contain plumbing for SVE as well as groundwater extraction.

The extracted vapor is treated using granular activated carbon (GAC) before being exhausted to the atmosphere. Extracted groundwater is piped to the on-site Groundwater Treatment Plant (GWTP) located approximately 900 feet northwest of the well field. Extracted groundwater is treated by air stripping and GAC before being discharged to the surface water by way of the NPDES outfall. The treatment system, combined with Natural Attenuation (NA) is supporting reductions of chemicals of concern: benzene, toluene, ethylbenzene, xylenes (BTEX), Methyl tertiary-butyl ether (MTBE), and naphthalene.

2012 – Groundwater monitoring was performed at the Pipeline Site which identified the presence of

BTEX, naphthalene, and MTBE in groundwater, but were not detected in surface water samples collected in the on-site water- bearing ditch. Benzene and MTBE are the only two compounds that exceeded clean up goals in groundwater. The treatment system is ongoing, combined with quarterly sampling events conducted each year to assess BTEX, naphthalene, and MTBE concentrations, which will continue until cleanup goals are met. Overall, the number of monitoring wells with measurable thicknesses of LNAPL as well as the magnitude of LNAPL thickness over time has decreased. In January 2012, the maximum LNAPL thickness was 1.63 feet; in April 2012, the maximum thickness was 0.01 foot; in August 2012, no wells had measurable LNAPL, and in

November 2012 the maximum measured thickness was 0.05 foot.

2013 to 2014 – Monitoring wells located within the CAFB Pipeline Site were scheduled to be sampled on a quarterly basis during the 12-month period of July 2013 through June 2014. Activities to maintain the Pipeline Site remediation system operation was scheduled during this time as well.

The treatment system was operational and active, combined with quarterly sampling events conducted each year to assess BTEX, naphthalene, and MTBE concentrations until cleanup goals are met. Free Product Recovery included gauging all wells and checking for free product on a bi-monthly basis. Any identified free product was pumped, or manually recovered, into containers for characterization and disposal.

2014 – Groundwater monitoring activities and data indicate that BTEX, naphthalene, and MTBE were present in groundwater at detectable concentrations, but were not detected in surface water samples collected in the on-site water-bearing ditch. Benzene and MTBE are the only two compounds that exceeded SSTLs in groundwater and MTBE only exceeded the RBSL in one well.

Based on the site’s conceptual model (CSM) and data collected to date, quarterly, semiannual, and annual sampling frequencies were recommended to improve efficiency.

2015 – Groundwater monitoring performed at the CAFB Pipeline Site confirmed the continued presence and dissolution of BTEX, naphthalene and MTBE in groundwater at the site. Two compounds (benzene and MTBE) were detected at concentrations exceeding SSTLs; CoCs were not detected in surface water samples collected from the on-site ditch. The groundwater/SVE remediation system, which was activated in March 2011, continued to effectively remove contaminant mass from the underlying aquifer.

February 2016 – 2016 Annual Corrective Action Progress Report (CAPR) required by SCDHEC covering the period February 1, 2016 through January 31, 2017. Site activities conducted during this reporting period included remedial system operation & maintenance (O&M), quarterly groundwater sampling, and the implementation of a groundwater recirculation program. SCDHEC provided comment December 12, 2017.

March 2016 – The groundwater recirculation program was implemented at the site on March 24, 2016 and remained in operation through September 22, 2017. The objective of this program was to modify the existing remedial infrastructure and incorporate a closed-loop groundwater recirculation system to enhance the in-situ bioremediation of dissolved-phase petroleum compounds at the Site.

The activities were completed using an oxygenation unit with the existing pump-and-treat (P&T) components and reinjecting amended groundwater to existing recovery wells. Clean-up goals (CG) for benzene (12 μg/L) were exceeded at eight locations; the CG for MTBE (40 μg/L) was exceeded at one location.
