Hoffman-Taff, Inc was a chemical manufacturer based in Missouri, established in 1946 and noted for its involvement in the hazardous waste crisis at Times Beach, Missouri. The firm specialized in producing various chemical products such as Agent Orange, which saw use during the Vietnam War, the deicing fuel additive Prist, and Pantoplex, a supplement for animal feed.
In December 1969, Hoffman-Taff was purchased by Syntex Agribusiness, transferring ownership of its operations and assets.
Verona, Missouri Manufacturing Site
The Verona plant, operational from 1949, was chiefly recognized for its production of Agent Orange. In 1968, a section of this facility was leased to NEPACCO for the manufacture of Hexachlorophene. Improper waste management by NEPACCO and associated contractors resulted in contamination affecting the plant and adjacent areas, including Times Beach.
After Syntex's acquisition in 1969, NEPACCO maintained production until 1972 when the FDA prohibited Hexachlorophene due to health risks. The Environmental Protection Agency later classified the site as a Superfund cleanup area in 1983.
By 2019, the former Hoffman-Taff location was partitioned between BCP Ingredients, which sustained chemical manufacturing activities, and Euticals, Inc., each controlling distinct portions of the original facility.
