| 4 | 26383 Highway 221, Enoree, South Carolina | Active exfoliation facility | 5,225 | Yes-February 16, 2000 | Yes | According to an EPA database compiled from W.R. Grace shipping invoices, this site received 5,225 tons of Libby ore between November 1967 and October 1985. Furthermore, reports published by the U. S. Geological Survey in 1975, 1980, 1985, 1990 and 1999 indicated that this facility was a vermiculite exfoliation plant. According to information gathered at the time of EPA’s investigation, this W.R. Grace facility was the largest vermiculite expanding plant in the world. The plant produced over 96,000 tons of vermiculite concentrate annually and expanded 30,000 tons of the concentrate annually. The plant was located on 400 acres and was a former mine site. A third of the product from this plant was expanded on site and the rest was shipped to W.R. Grace plants in Canada for expansion. Some of the vermiculite concentrate was shipped to Scotts Company facilities in Traveler’s Rest, South Carolina and in Marysville, Ohio (both of these sites are listed separately in this database). A fire retardant liquid form of vermiculite was also manufactured at this facility. EPA collected seven samples at this site on June 6, 2001. Four of the samples contained levels of asbestos that were less than 1 percent and three samples did not contain detectable levels of asbestos as analyzed using polarized light microscopy (PLM). EPA decided no further action was needed. |
