On August 24,2008 a fire at a vacant mill spread to the nearby Circleville Ag Products plant located at 347 E. Corvin street, Circleville, Ohio 43113. Radiant heat from the fire caused extensive damage to the above ground tanks by causing the valves to pop ,resulting in release of the contents. About 15 homes were evacuated . Fire was put out by the fire department by late morning but continued to smolder. Liquid chemicals and run off was contained within the dyked area. Pesticides, herbicides ,fertilizers and asbestos are the compounds of concern.
OSC and START mobilized and provided air monitoring . Ohio EPA oversaw the removal of liquids from the diked area by a contractor hired by the Responsible party. Hourly air monitoring around the primeter and a block away indicated non detectable amounts on the multirae, particulate meter and draeger tubes, except for one location directly in line of smoke where particuate matter was 0.3 mg per meter cube and CO was 6 ppm. Both constituents were well below the levels for any concern ( dust 1.0 mg per meter cube, CO 50 ppm).
