EPA finalizes Diaz Chemical Superfund site cleanup plans
NEW YORK — The U.S. Environmental Protection Agency (EPA) announced Wednesday that plans to clean up contaminated soil and groundwater at the Diaz Chemical Corp. Superfund site in Holley, N.Y., have been finalized.
The soil and groundwater are contaminated with volatile and semi-volatile organic compounds that were released when a safety valve at the facility ruptured in 2002.
EPA said it will treat the soil and groundwater in six areas using electrodes that will heat the soil and groundwater, causing the contaminants to evaporate and turn into vapor and steam. The vapor and steam will then be collected and treated. For contaminated ground water outside of the six sources of contamination, the EPA will rely on natural processes that allow the contaminants to disperse, dilute and degrade the ground water to meet federal cleanup levels.
The estimated total cost of the EPA’s plan is $14.5 million.
