5 14111 Scottslawn Road, Marysville, Ohio Active exfoliation facility 429,495 Yes-March 7, 2000 Yes According to an EPA database compiled from W.R. Grace shipping invoices, 429,495 tons of vermiculite ore from the Libby mine were shipped to this site between January 1967 and November 1980. According to a Scotts official, this facility began exfoliating vermiculite in approximately 1955 and used the vermiculite to produce lawn care and fertilizer products. After 1980, vermiculite ore was obtained from sources other than the Libby mine. At the time of EPA's visit, ore was being obtained from W.R. Grace located in Enoree, South Carolina, and Virginia Vermiculite, Ltd. located in Louisa, Virginia. (Both of these sites are listed separately in this database.) The company required its vermiculite suppliers to perform quality control analysis of the ore shipped to the Scotts facility. EPA obtained documentation that indicated that ore from the mine in Louisa, Virginia contained no asbestos. A document from W.R. Grace regarding the ore mined in Enoree, South Carolina indicated that the ore does contain tremolite asbestos, predominately the non-asbestiform type, rather than the fibrous, asbestiform type found in Libby ore that is regulated by the Occupational Safety and Health Administration. At the time of EPA's visit, the company had two other facilities that exfoliated vermiculite ore. These facilities were located in Travelers Rest, South Carolina, and Hope, Arkansas. (Both of these sites are listed separately in this database.) According to a company official, there were several former landfills on the Scotts site that could contain waste from the exfoliation of vermiculite ore from the Libby mine. The officials said they were negotiating with the state of Ohio to address these landfills as well as other environmental issues at the site. On November 29, 2000, EPA collected four soil samples from the Scottslawn Road site and none of the samples contained detectable levels of asbestos. The samples were analyzed using polarized light microscopy (PLM). On the basis of this information, EPA determined that no additional action was needed. The Agency for Toxic Substances and Disease Registry’s (ATSDR) health consultation report for this site can be found at ATSDR.
