KERAPCD RULE 113 SEPARATION AND COMBINATION          
LAST REVISED 05/00/89
          
          
          RULE 113 Separation and Combination - Adopted 1972-75
                   Renumbered 5/89
          
          I.    Multiple Emission Points

                If air contaminants from a single source operation are
                emitted through two or more emission points, the total
                emitted quantity of any air contaminant, limited in these
                Regulations cannot exceed the quantity which would be the
                allowable emission through a single emission point; and 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 exhaust gas volume
                through all emission points, unless the person responsible
                for the source operation establishes the correct total
                emitted quantity.

          II.   Combination (Subject to Separation)

                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 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 such source operation, these Regulations shall
                apply to each such source operation separately.

          III.  Combination (Not Subject to Separation)

                If air contaminants from two or more source operations are
                combined prior to emission, and the combined emission
                cannot be separated according to the requirements of
                Rule 113 II., 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.
