| 7 | 515 Madison Street, Kansas City, Missouri | Former exfoliation facility | 2,460 | Yes-April 12, 2000 | Yes | According to an EPA database compiled from W.R. Grace shipping invoices, 2,460 tons of vermiculite ore from the Libby mine were shipped to this site between January 1966 and August 1967. According to a 1953 report issued by the Bureau of Mines (at that time in the U.S. Department of the Interior), this facility had been a vermiculite exfoliation plant. At the time of EPA's visit, this site was leased by a company that manufactured fencing but previously had been used by a company that manufactured mattresses and also by a vermiculite processing facility. While walking through the building on the site, EPA determined the location of the original furnace used to expand vermiculite ore. Along a side wall there was residue and scrap material, the majority of which was bedding material. Vermiculite was visible underneath some of the bedding material. EPA collected six samples of dust/soil materials that contained at least some visible vermiculite flakes. Three samples, one analyzed using transmission electron microscopy (TEM) and two analyzed using polarized light microscopy (PLM), contained less that 1-percent asbestos. The remaining three samples, analyzed using PLM, did not contain detectable levels of asbestos. EPA determined no further action was needed. |
