Velsicol Chemical Corporation maintained two injection wells at its plant near Marshall, Illinois, to dispose of caustic wastes from pesticide production as well as contaminated surface runoff. In September 1965, the company began to inject the wastes into Devonian dolomites of the Grand Tower Formation at a depth of about 2600 feet. The wells accepted about 6 million gallons of waste monthly.

Cincinnati, OH. Report to Velsicol Chemical Corporation. 

In 1988, EPA prohibited the sale, distribution, and shipment of existing stocks of all canceled chlordane and heptachlor products. Subsequently, virtually all uses of heptachlor products were voluntarily canceled by the registrant, Velsicol Chemical Corporation (EPA 1990b). The only commercial use of heptachlor products still permitted is fire ant control in power transformers. Use of existing stocks of heptachlor-containing termiticide products in the possession of homeowners is also permitted (EPA 1990b). 

Data concerning occupational exposure levels of heptachlor are very limited. An industrial hygiene survey conducted in 1977 at the Velsicol Chemical Corporation, Memphis, Tennessee, a plant that manufactured heptachlor, detected heptachlor in workplace air at levels ranging from 0.025 to 0.202 mg/m (1.64-13.2 ppb) (Netzel 1981). Data from the National Occupational Exposure Survey (NOES) conducted by NIOSH from 1981 to 1983 were not available for heptachlor or heptachlor epoxide.

Four companies operating five facilities appear to be the primary U.S. producers of DEHP. These are Aristech Chemical Company in Neville Island, Pennsylvania Hatco Chemical Company in Fords, New Jersey Teknor Apex Company in Brownsville, Tennessee and Hebronville, Massachusetts and Tennessee Eastman Company in Kingsport, Tennessee (Mannsville Chemical Products Corporation 1999). SRI (1998a), however, lists only Tennessee Eastman and Aristech Chemical Company, as above, but also adds Velsicol Chemical Corporation in Chestertown, Maryland, which was not included in the above list. 

The indene-derived group. At the Velsicol Chemical Corporation in Chicago in 19 3, Dr. Julius Hyman was seeking new uses for the cyclopentadiene which was a by-product of U.S. synthetic rubber production and was already used by Velsicol for the manufacture of resins and varnishes by the Diels-Alder reaction (6). A literature search revealed Straus s 1930 synthesis of hexachlorocyclopentadiene ( hex ) and, since chlorinated dienes are frequently rather inert, Hyman was interested to determine if hex would participate in the Diels-Alder reaction, either with itself or with cyclopentadiene. 

Velsicol Chemical LLC, formerly Velsicol Chemical Corporation, designs, manufactures, markets and distributes high performance specialty chemicals and industrial intermediates, primarily based on benzoic acid and the organic compound cyclopentadiene. Its products include chlorendic anhydride and hexachlorocyclopentadiene (HEX). Chlorendic anhydride is corrosion resistant, fire resistant and has high UV stability, and is used in the synthesis of flame retardant polymers such as polyurethanes, unsaturated polyester and epoxy resins. HEX, a reactive intermediate used in the manufacture of agricultural pesticides in the production of flame retardants for the wire and cable industry and in the preparation of chlorendic anhydride. The company s products are produced primarily at a plant in Memphis, Tennessee Velsicol also maintains the Memphis Environmental Center (MEC), which focuses on managing legacy environmental liabilities. The firm is owned by Arsenal Capital Partners, a private equity firm.
