252:100-35-1.  Purpose

     The purpose of this Subchapter is to control emissions of carbon monoxide from stationary sources to prevent the Oklahoma Air Quality Standard from being exceeded and ensure that the present level of air quality in Oklahoma is not degraded.


252:100-35-1.1.  Definitions

     The following words and terms, when used in this Subchapter, shall have the following meaning, unless the context clearly indicates otherwise:
     "Existing source" means any gray iron cupola, blast furnace, basic oxygen furnace, petroleum catalytic cracking unit or petroleum catalytic reforming unit, in being on July 1, 1972, and not modified thereafter so as to increase the emission of carbon monoxide.
     "New source" means any gray iron cupola, blast furnace, basic oxygen furnace, petroleum catalytic cracking unit or petroleum catalytic reforming unit, in being after July 1, 1972.


252:100-35-2.  Emission limits

     (a)  Existing sources.  The emission of carbon monoxide from any existing source located in or significantly impacting (i.e., 500 μg/m³ on an 8-hour average) on a nonattainment area for carbon monoxide shall be reduced by use of complete secondary combustion of the waste gas generated.  Removal of 93 percent or more of the carbon monoxide generated shall be considered equivalent to complete secondary combustion.  Existing equipment subject to this Subchapter must meet the emission limitations as expeditiously as practicable, but no later than 3 years after nonattainment designation by the Administrator.

     (b)  New sources.  The emission of carbon monoxide from any new source shall be reduced by use of complete secondary combustion of the waste gas generated.  Removal of 93 percent or more of the carbon monoxide generated shall be considered equivalent to secondary combustion.
