Description of the source (including control equipm ent). Please see the attachments for source or process flow diagram: The processes evaluated by this emissions test program include the Line 621 melt furnace, the Line 621 forming and collection process, and the Line 621 curing oven/cooling process. The glass melt furnace fires natural gas and the furnace feed includes mixed batch and cullet. Emis sions from the glass melt furnace are controlled bya dry electrostatic precipitator (ESP). Emissions from the forming and collection process are controlled bya wet ESP and emissions from the oven and cooling process are controlled by thermal oxidizers. Industry/SCC/NAIS 327993
