Operation of any incinerator built after July 7, 1972, shall be prohibited if the incinerator emits more than three hundredths (0.03) grains of particulate matter per dry standard cubic foot of exhaust gas corrected to twelve percent (12%) carbon dioxide, without the contribution of carbon dioxide from auxiliary fuel.
Use of any incinerator which was in existence on July 7, 1972, is prohibited, if the incinerator has a capacity of more than four hundred (400) pounds per hour, or emits more than eight one hundredths (0.08) grains of particulate matter per dry standard cubic foot of exhaust gas corrected to twelve percent (12%) carbon dioxide, without the contribution of carbon dioxide from auxiliary fuel.
