Demolition crews on April 13 plan to bring down two towering smokestacks from the now-closed ASARCO copper smelter in West Texas.
About 50 people attended a public meeting Tuesday night in El Paso to hear from contractors and environmental officials.
Critics have raised public health and other pollution concerns with demolishing the 825-foot and 612-foot smokestacks at the site that closed in 1999.
Preservation efforts failed. The demolition is part of a $52 million remediation toward site redevelopment.
Mike Casbon of Brandenburg Industrial Service Co. says water mists will be used to help control the dust. He says material has also been removed from inside the stacks.
Officials say metal from the stacks will be recycled. The concrete will be used as fill at the site.
