The Mosaic Tile Plant Dump Site is located near a residential area outside of Zanesville, Muskinghum County, Ohio in Springfield Township. The Site is comprised of two adjacent properties (north and south parcels). The northern parcel, or operable unit (OU) 1 is the focus of the current removal action. A time-critical removal action was completed at OU2 site by the Marmon Group (Marmon) in 2004.
Collins and Aikman Accessory Mat (C&A), was the current owner and responsible party of the 3.5 acre northen parcel. C&A was financing the removal action until they declared bankrupcy. A CERCLA Settlement Agreement was executed between C&A, Marmon, and USDOJ in October, 2007, and the site property was placed in Custodial Trust. Trough terms of the Settlement Agreement, the Trust was funded by Marmon which financed the remainder of the removal action. The site will be managed by the Trust while funding is available.
The Site was used by the former Mosaic Tile Company to dispose of pottery waste such as glaze and tile in the 1950s and 1960s. The waste material was later found to contain high concentrations of lead. In the early 1990s, the Ohio EPA performed multiple site investigations and discovered total lead concentrations up to 45,000 ppm. TCLP concentrations for lead can be detected above the regulatory level of 5 mg/l (considered a RCRA hazardous waste). A large mound covers much of the OU1 area and is comprised primarily of layers of lead contaminated glaze, tile, soil and debris. Site assessment investigations found the thickness of the waste to vary from several inches to ~28-feet bgs. A fence was installed around the OU1 Site by C&A in 2003.
Five groundwater monitoring wells were installed in 2004 as part of the removal assessment work No lead concentrations above federal drinking water standards have been discovered.
Numerous investigations have been performed by C&A since the Administrative Order on Consent (AOC) was signed in 2003. C&A held up actual removal work for seveal years and at one point concluded that no environmental cleanup work was warranted. Removal activities finally began in earnest in Spring 2006.
See POLREPs 1-5 in the Documents Section below and POLREPs 6-10 above for past removal activities and more detailed information concerning the removal action.
