4 830 Highway 25 Bypass, Traveler's Rest, South Carolina Former exfoliation facility 17,005 Yes-February 17, 2000 Yes According to an EPA database compiled from W.R. Grace shipping invoices, this site received 17,005 tons of Libby ore between January 1967 and July 1981. According to reports issued in 1953 and 1964 by the Bureau of Mines (at that time in the U.S. Department of the Interior), this facility was a vermiculite exfoliation plant. Also, U.S. Geological Survey reports in 1970, 1975, 1980, 1985 and 1990 indicated that this facility was a vermiculite exfoliation plant. At the time of EPA's visit, Scott Sierra operated at this site; previously W.R. Grace and Zonolite had operated at the site. At the time of EPA's visit, Scott received enriched vermiculite ore from the W.R. Grace mill in Enoree, South Carolina (this facility is listed separately in this database), and then expanded or exfoliated the enriched ore for use in horticultural products. EPA collected three samples at the site on March 7, 2001—one soil sample from beside a railroad track, one soil sample from between railroad tracks that were located behind an ore storage area, and one sample from the vermiculite ore that had been received from the W.R. Grace facility in Enoree. When analyzed using polarized light microscopy (PLM), the soil sample collected between the railroad tracks contained less than 1-percent asbestos and the other two samples did not contain detectable levels of asbestos. EPA decided no further action was needed.
