Waste Site Cleanup & Reuse in New England

Zonolite W.R. Grace

Zonolite W.R. Grace, 19 Wemelco Way, Easthampton, Mass.

From 1963 to 1992, Zonolite/W.R. Grace leased the former Zonolite facility from Oldon Limited Partnership to operate an exfoliation plant. Zonolite/W.R. Grace received asbestos-containing vermiculite concentrate from the Zonolite mine in Libby, Mont., and produced attic insulation and Monokote fireproofing material. In 1992, Zonolite/W.R. Grace removed equipment, washed down the building and did air sampling. The building was empty from 1992 to 1997. From the late 1990s through 2000, JPS Acquisition Elastomerics Co. leased the building from Oldon as a warehouse. Oldon still owns the facility, which is used by a neighboring business, DOS Concrete Service, as a storage yard and warehouse. The site consists of several properties with asbestos-containing soils, including the former Zonolite plant, and adjacent properties. Except a railroad right-of-way owned by the city of Easthampton, the land is privately owned.

Analytical data generated by EPA, Mass DEP and W.R. Grace during 2000 and 2001 sampling investigations showed there were asbestos fibers in soils at levels ranging from trace to more than five percent. W.R. Grace hired a contractor to manage the cleanup. Work began Sept. 27, 2010 and more than 2000 cubic yards of contaminated soil were excavated and placed in a separate area where it was covered with fabric and at least two feet of clean fill. The work was finished by Oct. 28. 2011 and crews left.
