The aluminum recycling industry is expand±ng rapidly which has created the need for a second furnace at the Permit Holders' facility. Therefore, the Permit ·Holder petitions the City of Ramses' to operate two melt furnaces at its existing facility to satisfy these needs. SECOND MELT ~ACE A second melt furnace has been erected at the Permit Holders facility. This furnace is 7 ft in diameter by 9 ft long and is. designed to recover an average of 600 lbs per hour of aluminum. Four propane burners supply heat to the system. The furnace flue gases were directed to the above W.W. Sly Baghouse. This furnace was put into operation on August 10 and the Shaffer furnace was shut down to comply with the CUP requiremen~ and for maintenance. Table 1 summarizes the potential criteria pollutants that would be emitted to the atmosphere with both furnaces in operation producing an average of 1000 lbs per hour of aluminum for 24 hrs per day, 365 days per year with no pollution control device. This data was calculated from the emission factor listings in the publication EPA 450/4-90-003. Each emission is considerably less than the 25 tons per year allowed by the MPCA for an exempt status. The total maximum potential is 19.8 tons per year for all of the pollutants which is substantially less than allowablef Therefore, the facility will retain its exemption from requiring an air emission permit and shall be in compliance with MPCA regulations. We will be submitting this information to the MPCA in our application to operate two melt furnaces. EMISSION CONTROL An afterburner will be installed at each furnace to consume the organic compounds (smoke) before they exit the stack. This will assure opacity and odor control to within MPCA requirements. This alternative was selected to reduce the risk of fire from the W.W. Sly Baghouse~ However, the baghouse will be retained-on site and used in the event that the afterburners are' not in service.
