SUBPART B: FUEL COMBUSTION EMISSION SOURCES

 
Section 216.121 Fuel Combustion Emission Sources

SUBPART N: PETROLEUM REFINING AND CHEMICAL MANUFACTURE

 
Section 216.361 Petroleum and Petrochemical Processes
 

a)  A person must not cause or allow the emission of a carbon monoxide waste gas stream into the atmosphere from a petroleum or petrochemical process unless the waste gas stream is burned in a direct flame afterburner or carbon monoxide boiler so that the resulting concentration of carbon monoxide in the waste gas stream is less than or equal to 200 ppm corrected to 50 percent excess air, or the waste gas stream is controlled by other equivalent air pollution control equipment approved by the Agency under 35 Ill. Adm. Code 201.
 
b)  Regardless of subsection (a), any existing petroleum or petrochemical process using catalyst regenerators of fluidized catalytic converters equipped for in situ combustion of carbon monoxide may emit a carbon monoxide waste gas stream into the atmosphere if the carbon monoxide concentration of the waste gas stream is less than or equal to 750 ppm corrected to 50 percent excess air.
 
c)  Regardless of subsection (a), any new petroleum or petrochemical process using catalyst regenerators of fluidized catalytic converters equipped for in situ combustion of carbon monoxide may emit a carbon monoxide waste gas stream into the atmosphere if the carbon monoxide concentration of the waste gas stream is less than or equal to 350 ppm corrected to 50 percent excess air.

Section 216.362  Polybasic Organic Acid Partial Oxidation Manufacturing Processes

 
No person shall cause or allow the emission of any gases containing carbon monoxide into the atmosphere from any polybasic organic acid partial oxidation manufacturing process unless the total fuel value of the waste gas stream is less than 30 percent of that required for flame incineration of the waste gas stream at 793°C (1460°F) without heat exchange. Polybasic organic acid partial oxidation manufacturing processes not meeting the above conditions shall burn such waste gas stream in a direct flame afterburner to achieve a resulting concentration of carbon monoxide in such waste gas stream of less than or equal to 200 ppm or shall employ such other equivalent control method or equipment as may be approved by the Agency according to the provisions of 35 Ill. Adm. Code 201.
 
 

SUBPART O: PRIMARY AND FABRICATED METAL PRODUCTS

 

Section 216.381  Cupolas
 
No person shall cause or allow the emission of gases containing carbon monoxide into the atmosphere from any cupola with a manufacturer's rated melt rate in excess of 5 tons per hour, unless such gases are burned in a direct flame afterburner so that the resulting concentration of carbon monoxide in such gases is less than or equal to 200 ppm corrected to 50 percent excess air or such gas streams are controlled by other equivalent pollution control equipment approved by the Agency according to the provisions of 35 Ill. Adm. Code 201.
