Cleanup Action Update at CTS of Asheville

During the last week of May the Electric Resistance Heating (ERH) system was powered up to 50% (300 Volts per each electrode) and experienced no issues. The vapor recovery wells and thermal oxidizer were fired-up the beginning of June. Heating and recovery is now underway and working well.
Modems convey information from air monitors to a cloud-based data site. In June a couple of those monitors encountered a manufacturer glitch. Readings were taken by hand and the data was uploaded. There were no equipment failures involving extraction of the contaminant. 
More information about the above mentioned event, details on progression of cleanup at the CTS site, and general information on the site can be viewed on EPA’s CTS website here.

Also, EPA is inviting public input on how they’ve been doing keeping the community informed and engaged in the process of cleanup at the CTS site. You can print out and fill out a short survey here to let them know what they could be doing better to keep you informed about the site.

EPA Office of Inspector General releases report on CTS

Yesterday, the EPA Office of Inspector General released the results of its investigation into the agency’s handling of contamination at the CTS of Asheville site. This investigation has been underway since 2014, and members of POWER and other community members have participated in the gathering of information, including speaking out at a listening session.

Read: “Report: EPA did too little to warn residents near CTS,” Asheville Citizen Times, August 31

The investigation concluded that EPA Region 4’s actions since 2012 have done too little to protect residents’ health, and made 12 recommendations to improve the region’s procedures for site investigation, sampling, monitoring, and communicating with the public.

The Office of Inspector General report validates POWER’s long-standing concerns that the site-wide RI/FS hadn’t moved forward; that there should have been a routine ground water monitoring program in place; and that the bedrock/deep ground water should have been investigated further by now. POWER has pushed for the first step in remediation that is expected to begin this fall.

Proposed NC law would limit disclosure of harmful contaminants in water

Oppose House Bill 1005 / Senate Bill 779

People in our community around the CTS site know what it is like to fear that contaminated well water is affecting their families’ health. For many years while CTS has dragged its feet to cleanup the site, residents have had allies in the Buncombe County Health Department, who have always been willing to talk through information and explain the latest science about health risks of TCE and other chemicals.

Most families in the area now have filtration systems and/or public water line hookups, but not everyone in NC is so lucky. The NC General Assembly is considering a bill that would prohibit local and state health officials from warning residents about any contaminants found in their water that might harm their health unless they are among a limited set of chemicals that have federal or state standards, and the amount in the water exceeds that standard. This could keep health experts from providing helpful information to North Carolinians about whether their health could be at risk due to what’s in their drinking water!

Drinking water is not a partisan issue. Call your Representative and Senator now (look them up by county here, then click their name to view contact information), to ask them to oppose “Issuance of Advisories/Drinking Water Stds” bill!

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

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: 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.

Statement: POWER Supports Proposed Interim Remedial Action at CTS Superfund Site – Pushes for Increasing Treatment Area as EPA Tells CTS would get Better Results

The U.S. Environmental Protection Agency announced last week that it plans to approve an Interim Remedial Action to begin cleaning up the residual hazardous waste still saturating the ground at the CTS Superfund Site, which causes widespread ground water contamination at off-site private properties to the east and west of the old plant site.

CTS contractor AMEC Foster Wheeler proposes to treat approximately one acre of soil near the old building slab, where the light, non-aqueous phase liquid (LNAPL) contamination is concentrated (called the LNAPL Source Area).

EPA wants CTS to expand the treatment area, however, to include about one additional acre to the north, where extremely high levels of TCE exist also in soil, ground water, and weathered bedrock. TCE has been found in ground water there at up to 62,100 parts per billion (more than 12,000 times the maximum allowable level!), so it is a major source of contamination that continues to flow off-site.

A process called Electrical Resistance Heating (ERH) is proposed for the Interim Action

  • Electrodes driven into the ground conduct electric current into the subsurface
  • Ground heats up, and actually boils ground water
  • Hazardous chemicals including the primary site contaminant, trichloroethylene (TCE), and petroleum compounds are vaporized by the boiling
  • Vapors are collected by vacuum extraction wells so they can be treated
  • Any liquid LNAPL collected in vapor wells is collected and disposed off-site
  • Treatment would be completed in less than one year (after design)

AMEC studied various alternatives of remedial action earlier this year, but determined that none of the other methods would be as effective or quick, compared to ERH

  • LNAPL was not mobile enough to pump efficiently; residual LNAPL would remain.
  • Collection of liquid and vapor phase TCE using multi-phase extraction (MPE) would take up to ten years.
  • Washing LNAPL from soil by injecting chemical solution to flush it toward collection wells also inefficient; not all LNAPL removed and two years needed.
  • Injecting chemicals into the ground to destroy the TCE would require multiple injections to reach all LNAPL; would take three years.

POWER Action Group believes that ERH should be used, but that EPA should force CTS to increase the treatment area to include the additional part of the site to the north where so much TCE remains in the ground water. Otherwise, a major source of ground water contamination will still be there after AMEC treats its one-acre LNAPL Source Area, and off-site contamination may not be reduced much, if at all. If you agree, tell EPA to make CTS clean up the additional area NOW, as part of the Interim Remedial Action, to better protect off-site ground water.
