syntex facility

1ST ST

The Syntex Facility is a 180-acre site located in rural, predominantly agricultural area in Verona, Missouri. In October 1996, Syntex Agribusiness, Inc., sold to DuCoa L.P., a Dupont/Con Agra limited partnership. In the 1960's, Hoffman-Taff produced 2,4,5-T at the facility for use in the production of the defoliant more commonly known as Agent Orange. Hoffman-Taff leased a portion of the plant in 1969 to the Northeastern Pharmaceutical Chemical Company (NEPACCO) where hexachlorophene was produced from 1969 to 1971. The production of hexachlorophene generated waste streams containing dioxin. Dioxin residues were disposed of in five areas at the Verona facility. The major areas identified as being contaminated are: the slough area; lagoon area; spill area/irrigation area; burn area; and trench area. In 1989, Syntex excavated and transported the wastes from the burn, slough, irrigation, and lagoon areas to a mobile incinerator temporarily located at the nearby Denney Farm site, to destroy the dioxin. The incineration was completed in 1989. The population within 3 miles of the Syntex Facility site is approximately 650 people. The active portion of the facility is located within the Spring River 100-year flood plain.
