SAN JOAQUIN VALLEY UNIFIED AIR POLLUTION CONTROL DISTRICT
RULE 1150 - SEPARATION AND COMBINATION
(Adopted June 18, 1992, Amended December 17, 1992)
This rule shall apply to any single source operation which emits or may emit air contaminants through two (2) or more emission points or to any two (2) or more source operations where the air contaminants are combined prior to emission.
2.0 If air contaminants from a single source operation are emitted through two (2) or more emission points, the total emitted quantity of any air contaminant limited by these Rules and Regulations cannot exceed the quantity which would be the allowable emission through a single emission point. The total emitted quantity of any such air contaminant shall be taken as the product of the highest concentration measured in any of the emission points and the combined exhaust gas volume through all emission points, unless the person responsible for the source operation establishes, to the satisfaction of the APCO, the correct total emitted quantities.
3.0 If air contaminants from two (2) or more source operations are combined prior to emission and there are adequate and reliable means reasonably susceptible to confirmation and use by the APCO for 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, these regulations shall apply to each such source operation separately.
4.0 If air contaminants from two (2) or more source operations are combined prior to emission, and the combined emission cannot be separated according to the requirements of Section 3.0 of this rule, these regulations 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 regulations on any of the source operations whose air contaminants are so combined.
