Regulatory Applicability
AQCC Regulation 1 _
This source is subject to the opacity requirements for flares in Section II.A.5:'No owner or operator
of a smokeless flare or other flare for the combustion of waste gases shall allow or cause
emissions into the atmosphere of any air pollutant which is in excess of 30% opacity.'
AQCC Regulation 2 _
Section I.A applies to all emission sources. "No person, wherever located, shall cause or allow the
emission of odorous air contaminants from any single source such as to result in detectable odors
which are measured in excess of the following limits: For areas used predominantly for residential
or commercial purposes it is a violation if odors are detected after the odorous air has been diluted
with seven (7) or more volumes of odor free air."
