In September 1998, EPA issued to DuPont for the Waynesboro Site the Corrective Action portion (i.e., HSWA permit) of their site Resource Conservation and Recovery Act (RCRA) Permit (Permit No. VAD003114832) to conduct investigations and determine if corrective measures, of on-site solid waste management units (SWMUs) is necessary. The RCRA Permit was renewed by Virginia Department of Environmental Quality (DEQ) in 2009. The Permit was further in revised in 2014 to include Offsite concerns, specifically the South River and floodplains, designated as Area of Concern (AOC) 4 in the Permit.
Under EPA direction, DuPont prepared a RCRA Facility Investigation (RFI) Plan and a Land Use Report. The RFI investigation was conducted in three phases, starting in 2000. In December 2014, DuPont submitted a Final Comprehensive RFI Report covering the investigation. EPA approved the Final RFI Comprehensive in May 2015.
DuPont submitted a draft On-Site Corrective Measures Study (CMS) Report to EPA in June 2015. The CMS is an evaluation of potential remedies to deal with releases discovered during the investigation phases. EPA will prepare a Statement of Basis for public comment in late 2015, which will propose a remedy for the onsite releases.
DuPont submitted a Class 2 permit modification request to incorporate an off-site Area of Concern (AOC 4) in to the facility permit on November 19, 2013. AOC-4 includes the South River downstream of the former DuPont Waynesboro facility and parts of the South Fork Shenandoah River. The permit modification request was approved on the Virginia Department of Environmental Quality (DEQ) on February 4, 2014.
Under the direction of the DEQ, DuPont prepared a RFI for AOC-4 that included ecological and human health risk assessments. The RFI is currently undergoing regulatory review. In addition, an Interim Measures Work Plan for the first two river miles has been submitted by DuPont and approved by DEQ on March 25, 2015. This plan focuses on bank stabilization and removal designed to reduce loading of mercury contaminated soils in to the South River.

DuPont began operations at the Site by manufacturing acetate flake and yarn in 1929. In 1958, DuPont began producing Orlon, the plants second fiber. The acetate flake and yarn process and Orlon process were discontinued in 1977 and 1990, respectively. In the interim, Lycra7 production had begun in 1962, with Permasep production beginning in 1969 and BCF Nylon in 1978. Only Lycra continues to be made today.
The 177-acre site is located in the southeastern portion of the city along the South River in an industrially zoned area.
The primary contaminant at the former DuPont Waynesboro Site is mercury, which was used in making acetate flake.
No institutional controls are currently in place.
The site is under continued use.
RCRA Corrective Action activities at this facility are being conducted under the direction of the EPA Region 3 with assistance from the Virginia DEQ.
