EPA approves expanded interim plan for North Carolina Superfund Site

The Environmental Protection Agency (EPA) recently finalized an expanded interim cleanup plan for North Carolina’s CTS Asheville Inc. Superfund Site, which will use $9 million to address a 3.1-acre property.

Formerly housing an electronic component manufacturing facility, the site’s soil and groundwater is now contaminated with trichloroethene (TCE) and other volatile organic compounds (VOCs). The finalized cleanup plan expands the original site area of one acre and will clean up nearly 210,000 cubic yards of material. The site will be treated for TCE and non-aqueous phase liquid (NAPL), using electrical resistance heating (ERH), which vaporizes contaminants by heating the ground, and in-situ chemical oxidization (ISCO), which injects chemicals into the ground to break down the contaminants.

The expansion of the treatment area was based on an Oct. 13, 2015 public meeting and public comments received by the EPA. Following this input from the community, CTS submitted treatment option evaluations to the EPA, which has now selected an interim remedy with an estimated cost of $9 million, to be borne by those responsible for the site’s pollution.

TCE can negatively impact human health, affecting the central nervous system, liver, kidneys, immune system and endocrine system, and it has been linked to some forms of cancer.
