This site is located at 2502 South Garnsey Street, Santa Ana, Orange County, California.
From 1972 through 1993, the W.R. Grace & Company site at 2502 South Garnsey in Santa Ana, California, processed vermiculite mined in Libby, Montana. This vermiculite was contaminated with asbestos.
The facility exfoliated ("popped" or expanded) vermiculite to manufacture insulation, fireproofing (brand name: Monokote), masonry fill, pool cushion, and various horticultural products. Over 400,000 tons of vermiculite were processed at this site.
While the facility no longer processes vermiculite, W.R. Grace still owns and operates the four-acre site. Land use immediately surrounding the site is a mix of commercial, light industrial, and residential. The nearest homes lie within one-quarter mile of the site. According to the U.S. Census, over 35,000 people were living within one mile of the site in 1990.
Recent EPA environmental samples from the site showed low levels of Libby asbestos in soils in several areas. Much of the site, however, is paved. No vermiculite or vermiculite waste stockpiles are present at the site. Air samples collected inside the building detected no asbestos fibers. One of three dust samples collected inside the building indicated the presence of very low levels of Libby asbestos in surface dust.
