El Paso smokestacks set to fall on 13 April.
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.
