Update: you can still comment on cleanup plan through Nov. 29

Posted on Nov 2, 2015

The highly-contaminated CTS of Asheville Superfund site is now in the comment phase of the interim remedial action plan! After the October 13 public meeting, the comment period was extended through the end of November! Here’s a quote from the EPA Region 4 update sent out to the community:

The majority of the comments received to date encourage EPA to expand the proposed one-acre treatment area to include additional acreage to the north. Data shows elevated levels of trichloroethene (TCE) in groundwater north of the proposed one-acre treatment area, near monitoring well clusters MW6 and MW7. EPA recently discussed the community’s comments with representatives of CTS Corporation. As a result, CTS has requested a 30-day extension to the initial comment period. During the extension, CTS plans to prepare and submit an Addendum to the Focused Feasibility Study that will evaluate Electrical Resistance Heating (ERH) and In-Situ Chemical Oxidation (ISCO) for the expanded treatment area north near MW6/MW7.

This is good news, but as many public comments as possible will make it even more likely that a larger area of the site will be cleaned up in the immediate future! Please consider submitting a brief email to Remedial Project Manager Craig Zeller: zeller.craig@epa.gov. Comments are due by November 29, 2015.

Suggested email/comment:

Dear Mr. Zeller,

The proposed treatment area at the CTS of Asheville site should be expanded to include an adjacent highly contaminated source area (near Monitoring Wells 6 and 7) beyond the proposed one-acre treatment area to the north. Sampling data shows this additional area presents a potent source of TCE that will continue to migrate to the west and southeast and contaminate off-site ground water if left untreated.

In the interest of effectiveness, cost-efficiency, and responsible protection of human health and the environment, we ask that EPA exercise its Superfund authority to expand the treatment area. Doing so will make the interim remedial action more effective as the Electric Resistance Heating (ERH) method is implemented by ensuring that re-contamination of the treated area is not as likely to occur prior to implementation of the long-term, site-wide remedy.

Please move ahead as quickly as possible with the remedial cleanup action and suggested expansion.

Thank you for your consideration of this important request.
