NOTICE OF INTENT TO REMEDIATE
Former DuPont Brevard Site
1300 Staton Road
Cedar Mountain, Transylvania County, North Carolina
EPA ID No. NCD 003 152 329
This is a notice to the public of a request by E.I. du Pont de Nemours and Company (DuPont) to pursue remediation of the contamination at the Former DuPont Brevard Facility (site) using site-specific remediation standards as opposed to unrestricted use standards. Contaminated site media include groundwater, soil, sediment and surface water. Information about the nature and extent of the contamination at the site is presented in the Remedial Investigation Report which is available electronically for review at: https://deq.nc.gov/about/divisions/waste-management/hazardous-waste-section/dupont-facility-brevard-nc.
DuPont has been performing investigation and remediation activities at the site since the 1990s. The site was used to produce high purity silicon from 1957 to 1962 and medical imaging (X-ray films) from 1962 to 2002. Approx-imately 1,100 samples were collected at the site during four comprehensive investigations and numerous remedial actions have been completed. Key remedial actions include demolition and removal activities of the former plant, removal and recycling/relocation of X-ray film waste, installation of cap/covers over former landfill/disposal areas, and installation of a groundwater treatment system for the DuPont State Recreational Forest (DSRF) Visitor Center water supply well. To satisfy additional remedial action objectives for the site, active remediation is proposed at two evaluation units (Solid Waste Management Unit [SWMU] 11 and SWMU 17. A vegetative cap will be designed and installed for final closure of SWMU 11 and in-situ solidification/stabilization for soil and waste will be designed and installed within SWMU 17. Institutional controls and engineering controls (e.g., fencing) will also be implemented throughout the site. Site investigations and proposed additional remedial actions are documented in reports that are available for review at the Transyl-vania County Library in Brevard, North Carolina and online at: http://www.uspioneer.com/projects/FormerDupontBrevardFacility/download.htm.
DuPont is preparing a remedial action plan in accordance with N.C.G.S. 130A-310.65 through 310.77 which allows use of site-specific remediation standards that are expected to pose no unacceptable risk to human health and the environment. Once the North Carolina Department of Environmental Quality (NC DEQ) approves the proposed remedial action plan, a second Public Notice will be issued providing for a 45-day public comment period.
In addition, a public meeting will be held on Thursday June 23rd from 6:00 pm to 8:00 pm in the Rogow Room at the Transylvania Public Library. Information about the proposed remediation action plan will be presented during the meeting. DuPont representatives will be available to answer questions and receive comments from the public. Comments received on or before July 25, 2016 will be incorporated, as appropriate, in the remedial action plan.
