RULE 3.5 - COMBINATION OF EMISSIONS
(Adopted 6/91)

  1. If air contaminants from two or more source operations are combined prior to emission and there are adequate and reliable means reasonably susceptible to confirmation and use by the Air Pollution Control Officer for establishing a separation of the components of the combined emission to indicate the nature, extent, quantity and degree of emission arising from each source operation, then all of the applicable prohibitions shall apply to each source operation separately.
  2. If the air contaminants from two or more source operations are combined prior to emission, and the combined emissions cannot be separated according to the requirements of section 'a', of this Rule, then all applicable prohibitions shall be applied to the combined emission as if it originated in a single source operation, subject to the most stringent limitations and requirements placed by these prohibitions on any of the source operations whose air contaminants are so combined.
