Ohio EPA to Hold Meeting About Latest Cytec Draft Permit Modification, Cleanup

Ohio EPA representatives will be in Marietta on July 16, 2012, to accept comments about a draft hazardous waste permit modification for Cytec Industries Inc. (1405 Greene St., Marietta). The permit, if issued final, would authorize Cytec to address soil and ground water contamination at specific areas of the Washington Co. site according to Ohio EPA's proposed remedies to protect human health and the environment.

Public Hearing

The information session and public hearing will be held at 6 p.m. at the Lafayette Hotel, 101 Front St., Marietta. Ohio EPA places a high priority on public involvement and encourages citizens to become involved in the decision-making process. During the information session, Ohio EPA will explain the draft permit and answer questions about it. During the hearing, the public can submit comments for the record that will be considered before Ohio EPA issues or denies the final permit modification for the remedy of the above listed areas.

Ohio EPA held public meetings in 2010 and 2011 to answer the public's questions about clean-up measures at other areas of the site. Last year, the Agency issued Cytec a final permit modification to implement a combination of approved corrective measures for those areas. Additionally, Ohio EPA required Cytec to further investigate ground water conditions around the north landfill and submit a revised corrective measures study. Now, public comments are being solicited for the Agency's consideration prior to taking any permit action specific to that landfill, Duck Creek, the east storage pad, concrete tank saddles and drainage swale.

Proposed Remedies

The Agency's proposed remedy for the landfill is to anchor a clay slurry wall into bedrock along its west and south sides to prevent ground water from flowing in. The existing soil/clay cap would be augmented (primarily along the east side) with additional soil and a synthetic liner. A clay berm (or equivalent barrier) along the northeast portion of the landfill would protect against infiltration of water during flood events. These efforts and hydraulic control for ground water should expedite ground water cleanup. Additionally, an environmental covenant would: identify this area as having waste remaining in place; forbid the cap or its components from disturbance without Ohio EPA consent; and restrict ground water use. Long term monitoring (e.g., of cap, ground water, etc.) would assess the remedy's adequacy.

Ohio EPA's proposed remedies for the other areas include periodic stream and sediment monitoring in Duck Creek; excavation of contaminated soils at the east storage pad; and a continuation of a waste cap in the concrete tank saddle area. Based on recent soil sampling, Ohio EPA believes no further action is required at the drainage swale.

Site History, Previous Cleanups

The Cytec site has a long history of industrial use. Specialty chemicals were manufactured there until 1996. Prior to modern environmental laws, some industrial process waste chemicals were disposed of on site in ponds, landfills and other areas. Some of the most contaminated areas at the site have been addressed. In 2004, Ohio EPA issued Cytec a hazardous waste permit that required the company to investigate and clean up contamination. Two ponds were cleaned and capped, several landfills and disposal areas were excavated and some contaminated soil and piping was removed.

Public Comments

In addition to oral comments provided at the July 16 public meeting about the draft hazardous waste permit modification, Ohio EPA will equally consider written comments received through July 28, 2012. Interested parties can send comments to Ohio EPA, Division of Materials and Waste Management, Processing and Records Management Unit, P.O.
