Hunter Army Air Field

SECTION 1.0 INTRODUCTION

Hunter Army Air Field, located in Savannah, Georgia, United States, is a military airfield and subordinate installation to Fort Stewart located in Hinesville, Georgia. Hunter features a runway that is 11,375 feet (3,468 m) long and an aircraft parking area that is more than 350 acres

(1.4 km²). The runway and apron, combined with the 72,000 sq ft (6,689 m²) Arrival/Departure

Airfield Control Group (A/DACG) Facility and nearby railhead, allow the 3rd Infantry Division from nearby Fort Stewart to efficiently deploy soldiers and cargo worldwide. NASA identified

Hunter as an alternate landing site for the Space Shuttle orbiters.

LIGHTNING ROAD

1.1 Environmental History:

Hunter Army Airfield (AAF) is located near Savannah, GA. The Lightning Road (Rd.) site is located on the northwest side of the airfield, where a four-inch aboveground fuel pipeline crosses beneath North Lightning Rd. In January 2015, contractor personnel reported a fuel release to a subsurface pipeline sump near the north side of North Lightning Rd. The release was estimated to be approximately 20 gallons. Initial response actions included excavation and off-site disposal of approximately 170 tons of impacted soil from the area.

Subsurface investigations were performed from April to October 2015. These investigations included advancement of soil borings to delineate residual soil contamination, and installation of eight groundwater monitoring wells to assess groundwater impacts. Soil contaminant concentrations were below GA EPD Soil Threshold Levels, and groundwater monitoring results were below In-Stream Water Quality Standards. However, an area of petroleum-impacted soil was identified near the area of the product sump. DLA elected to remove the petroleum impacted soil in an effort to further reduce potential impacts to the environment and to eliminate the need for post-remediation monitoring. The additional soil excavation was performed in August and

September 2016.

A Corrective Action Plan (CAP)-Part A was submitted to GA EPD on January 22, 2018, describing results of the site investigations and remedial actions. The Final Soil Excavation

Completion Report was also submitted with the CAP-Part A recommending a No Further Action

(NFA) determination for the site.

Hunter Army Airfield (AAF) is collocated with Fort Stewart Army Base. The Pumphouse 2 site formerly included five 50,000-gallon jet fuel USTs that were closed in October 2014. Soil samples collected during UST closure activities did not yield contaminant of concern (COC) concentrations above GA EPD soil threshold levels. However, one of two groundwater samples collected during UST closure exhibited polynuclear aromatic hydrocarbon (PAH) concentrations above applicable water quality standards.

A subsurface investigation was performed in October 2016. Ten soil borings were advanced at the site for soil characterization and sampling. No COCs were detected in soil above threshold levels. Ten temporary groundwater wells were installed at the site after soil boring was completed. Groundwater sampling revealed low-level detections of two PAHs above applicable water quality standards at three temporary well locations.2

A Corrective Action Plan (CAP)-Part A was submitted to GA EPD in January 2018, describing results of the initial and subsequent site investigations. Based on these results, as well as a Water

Resources Survey that identified no public or private water supply wells within a 0.5-mile radius of the site, the CAP-Part A recommended a No Further Action (NFA) determination for the site.2

GA EPD approved NFA for the site in March 2019

PUMPHOUSE 3

1.2 Environmental History:

Hunter Army Airfield (AAF) is collocated with Fort Stewart Army Base. In December 2011, 9,733 gallons of jet propellant (JP)-8 fuel were released at the Pump House 3 on the Petroleum, Oil, and Lubricant (POL) Island at Hunter AAF.

After initial emergency response, an interim measure to recover free product and vapors was initiated. This included the installation of a recovery well and vacuum system for free product recovery (FPR). The recovery well and vacuum system was operated until January 2012;

however, groundwater monitoring and FPR via peristaltic pumps at the site continued. A

Corrective Action Plan (CAP)-Part A documenting results of the investigations and interim remedial measures was submitted to GA EPD in June 2012.

A CAP-Part B was submitted to GA EPD in October 2014. The CAP-Part B noted that remedial actions and FPR were complete, and projected that quarterly monitoring and annual reporting would occur between November 2014 and February 2016. Monitoring would occur until groundwater contaminants of concern (COCs) fall below approved Alternate Concentration

Limits (ACLs). Groundwater monitoring was planned around the known schedule for a Military

Construction (MILCON) project at the time of the CAP Part B’s publication, as the monitoring wells were scheduled for removal prior to the MILCON. All monitoring wells at the site were decommissioned in 2015.

The MILCON project to remove USTs, demolish Pump House 3, and excavate impacted oil was completed in September 2016. A Monitoring Well Installation Work Plan for the reinstallation of groundwater monitoring wells and resumption of monitoring to comply with the CAP-Part B was submitted to GA EPD in October 2017. The work plan stated that monitoring will continue until the remedial endpoints specified in the CAP Part B are achieved and the site is eligible for No

Further Action (NFA) status.4 GA EPD approved the Monitoring Well Installation Work Plan in

February 2018.

In May 2018, 14 new monitoring wells were installed and sampled. The report for the May 2018 groundwater monitoring event, dated July 2018, noted one low-level polynuclear aromatic hydrocarbon (PAH) exceedance at one well. The report recommended one additional monitoring event to confirm COC concentrations, followed by NFA determination for the site. In a response letter dated October 2018, GA EPD indicated that one year of quarterly groundwater monitoring and one year of semiannual groundwater monitoring would be required to demonstrate that the site meets criteria for NFA.

SECTION 2.0 GENERAL CONTRACT REQUIREMENTS

2.1 Remedial Requirements
