MACT Standards

Last month’s test results from the Heritage incinerator in East Liverpool, Ohio, confirm that air emissions of dioxin are more than 50 times lower than the national standard for clean air. Results of the Maximum Achievable Control Technology Rule (MACT) for Hazardous Waste Combustors tests, which have been forwarded to U.S. and Ohio environmental agencies, averaged 0.004 billionths of a gram in each cubic meter of air that flows from the stack. The EPA’s clean air standard allows 0.2 billions of a gram in each cubic meter of air. Heritage was the first commercial Hazardous waste incinerator in America to demonstrate compliance with all of the rule’s requirements, including the one for air emissions of dioxin.
