EPA issued the Final Decision and Response to Comment (FDRTC) on November 16, 2012, for the Martinsville site. The FDRTC incorporated the remedy detailed in the Statement of Basis, which restricts the Facility to industrial use through compliance with and maintenance of institutional controls, restriction on groundwater use, continued maintenance of existing soil capping over ash piles, and recovery of trichloroethylene (TCE) from groundwater. Virginia DEQ issued a Corrective Action Permit in 2013 to implement the selected remedy.
In June 2014, the Corrective Measures Implementation Work Plan was approved. The CMI WP provided a general description of the proposed remedial measures and presented an implementation schedule for the design and construction of the proposed soil and groundwater remedies. The final remedial measures selected are as follows:
- Implement zero-valent iron clay treatment and installation, maintenance, and monitoring of a soil cap at SWMU H1.
- Install, maintain, and monitor an asphalt cap at AOC Fire Training Area (FTA).
- Implement soil vapor extraction treatment for source soils and enhanced biological stimulation of groundwater at AOC DuPont Precision Concepts (DPC).
- Conduct the required inspection and maintenance of the existing soil and vegetative caps at nine SWMUs and AOCs.
- Continue long-term groundwater and surface-water monitoring as necessary to evaluate remedial effectiveness until clean-up goals are met.
- Implement additional institutional and engineering controls (ICs and ECs) as necessary to prevent current and potential future exposure to contamination.
- In addition, inspection and maintenance of the asphalt cap at SWMU I, the Former Lab Disposal Pits, will be included in the final remedy for the site although this activity is not specifically required by the RCRA Permit.
An environmental covenant, pursuant to the Virginia Uniform Environmental Covenants Act (UECA; Va. Code, § 10.1-1238, et seq.), was recorded with the deed for the DuPont Martinsville site on July 22, 2014. The purpose of the UECA is to notify prospective purchasers of the site of land use restrictions. The current owner and future owners of the site are obligated to comply with the recorded restrictive covenant.
The 30%, 90%, and 100% Design Reports as required by the RCRA Permit were submitted an approved by VDEQ. The 100% Design Report was submitted as a Class 1 permit modification incorporating the final design of the remedial measures.
Located on DuPont Road in Henry County, Martinsville, Virginia, the DuPont facility has been part of this Piedmont region community since the early 1940s. The DuPont Martinsville site occupies approximately 465 acres on a large bend of the Smith River immediately adjacent to the City of Martinsville, Virginia. The Martinsville Plant began operating in 1941, producing primarily nylon fiber along with spinnerettes for the manufacturing of nylon and other fibers. Nylon manufacturing ceased in June 1998. Spinnerettes continued to be produced by DuPont Precision Concepts until the facilities were sold to INVISTA S. a r. l. (Invista), a subsidiary of Koch Industries, Inc., on April 30, 2004. Invista Precision Concepts continues spinnerette manufacture at the site.
In February 1986, Virginia Department of Environmental Quality (VDEQ), issued Waste Management Permit VAD 003114865 to DuPont for the operation of a hazardous waste storage pad at the facility. The VDEQ permit addresses the provisions of the Virginia Waste Management Act. The complete Resource Conservation and Recovery Act (RCRA) permit for the facility consisted of the VDEQ Permit and a Corrective Action Permit (CA Permit) issued by United States Environmental Protection Agency (EPA) in July 1991. The CA Permit required DuPont to conduct a comprehensive RCRA Facility Investigation (RFI), prepare an RFI Report, and prepare a Corrective Measures Study (CMS).
DuPont conducted a comprehensive RFI and submitted the Comprehensive RFI Report to EPA in 2007. During the RFI, SWMU I was recommended for an interim stabilization measure (ISM), which consisted of treating the soil source via zero-valent iron/clay mixing. At the conclusion of the RFI, the 2007 Comprehensive RFI Report recommended that one SWMU and two AOCs move forward into a CMS to evaluate potential remedial measures. Two additional supplemental sampling events were conducted, as required by EPA, to evaluate the Smith River TMDL and the potential influence of Unit D, the inactive ash pond. EPA approved the TMDL-specific supplemental report in January 2010, the supplemental report related to Unit D in June 2011, and the 2007 Comprehensive RFI Report in August 2011. The Corrective Measures Study for DuPont Martinsville Site was submitted to EPA in July 2008 and was approved in January 2010. Following approval of the CMS, EPA issued a Statement of Basis detailing the selected remedial measures for the site. A renewed RCRA Permit incorporating the selected remedial measures was issued on December 21, 2013 and is in effect until December 21, 2023.
Volatile organic compounds are the main constituents detected in groundwater at the site. These compounds primarily consist of solvents including carbon tetrachloride, tetrachloroethene and trichlorethene.
The Final Remedy implemented through the modification of the Facility’s Hazardous Waste Permit requires maintenance of institutional and engineering controls. The Facility also recorded an environmental covenant under the Uniform Environmental Covenant Act (UECA) to maintain these controls.
