Description of the source (including control equipm ent). Please see the attachments for source or process flow diagram: Basalt, dolomite, and limestone are fed to a coke-f ired cupola furnace and melted to be formed into mineral wool. Emissions from this cupola are exhausted through a baghouse, a regenerative thermal oxidizer and a single exhaust stack (Stack 101). The stack is 8.5 feet in diameter and is equipped with four test ports, each six inches in diameter. After being formed into mineral wool, the mat is fed through curing ovens where the mineral wool resinreaction is cured. Emissions from the curing ovens are exhausted through a filterhouse, an afterburner, and a single exhaust stack (Stack 102). This stack is 26 inches in diameter. Industry/SCC/NAIS 327993
