Description of the source (including control equipm ent). Please see the attachments for source or process flow diagram: The exhaust stacks to be evaluated by this emissions test program are (1) one exhaust stack (EPN 21) associated with the Line 91 electric steel shell melt furnace,(2) four exhaust stacks (EPN 16 through 19) associated with the Line 91 Rotary Glass Forming process, (3) one exhaust stack (EPN 20) associated with the Line 91 CuringOven, (4) four exhaust stacks (EPN 1, 2, 4, and 5) associated with the Pot and Marble Forming process, and (5) one exhaust stack (EPN 3) associated with the Pot and Marble Curing Oven For Line 91, glass batch is fed to two electric melters which flow to a forehearth. From the forehearth it flows through four spinner modules where the binder is added to form fiberglass. Exhaust from the electric melt furnaces and forehearths are routed through a dust collector and then to the ambient air through stack EPN 21. Exhaust from the four Line 91 collection modules is routed through four wet scrubbers (one for each collection module) and then to the ambient air through exhaust stacks EPN 16 through EPN 19. Exhaust from the curing oven and cooling table is routed through a wet scrubber and then to the am bient air through exhaust stack EPN 21. For the Pot and Marble fiberglass production proces s, glass marbles are melted by electric pots and then binder is added. A mixture of natural gas and combustion air(flame attenuation) then bonds molten glass and fibers. A fiberglass mat forms that goes into a curing oven (natural gas and combustion air). Product cools off , it trimmed, backed and packaged. Exhaust from the Pot and Marble mat collection process is routed to the ambient air through four exhaust stacks (EPN 1, 2, 4, and 5). Exhaust from the Pot and Marble curing oven is routed to the ambient air through exhaust stack EPN 3. Industry/SCC/NAIS
