Superfund Site Profile
The Diaz Chemical Corporation (Diaz Chemical) site is located in Holley, New York. The area includes the Diaz Chemical facility and parts of the surrounding residential neighborhood. Following an accidental release of a chemical mixture in 2002, members of the public complained of acute health effects. Residents voluntarily relocated from some of the homes in the neighborhood to area hotels with assistance from Diaz Chemical. In May 2002, the Environmental Protection Agency (EPA) assumed responsibility for the relocation expenses of the residents who remained relocated at that time, secured the site and removed contaminated materials. In June 2003, Diaz Chemical filed for bankruptcy and abandoned the facility, leaving behind large volumes of chemicals in drums and tanks. Immediate cleanup actions at the site have protected immediate threats to human health and the environment. A thermal treatment remedy was selected for the site in 2012. Design and construction efforts related to the site’s long-term cleanup are underway.
