(Last Revised 09/12/96)

A. If air contaminants from two or more source operations are combined prior to emission and there are adequate and reliable means reasonably susceptible for confirmation and use by the Air Pollution Control Officer in establishing a separation of the components of the combined emission to indicate the nature, extent, quantity, and degree of emission arising from each such source operation, the Rules and Regulations shall apply to each source operation separately.

If air contaminants from two or more source operations are combined and the emissions cannot be separated according to the requirements of Section A above, the Rules and Regulations shall be applied to combined emissions as if it originated in a single source operation subject to the most stringent limitations and requirements placed by the Rules and Regulations on any of the source operations whose air contaminants are so combined.
