PART 217 NITROGEN OXIDES EMISSIONS
SECTION 217.141 EXISTING EMISSION SOURCES IN MAJOR METROPOLITAN AREAS
Section 217.141 Existing Emission Sources in Major Metropolitan Areas
No person shall cause or allow the emission of nitrogen oxides into the atmosphere in any one hour period from any existing fuel combustion emission source with an actual heat input equal to or greater than 73.2 MW (250 mmbtu/hr), located in the Chicago or St. Louis (Illinois) major metropolitan areas to exceed the following limitations:
a) For gaseous and/or liquid fossil fuel firing, 0.46 kg/MW-hr (0.3 lbs/mmbtu) of actual heat input;
b) For solid fossil fuel firing, 1.39 kg/MW-hr (0.9 lbs/mmbtu) of actual heat input;
c) For fuel combustion emission sources burning simultaneously any combination of solid, liquid and gaseous fuel, the allowable emission rate shall be determined by the following equation:
E = (AG + BL + CS) Q
