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." Part A: An APEN is required for this source because uncontrolled VOC emissions exceed one ton per year in a nonattainment area for ozone. Part B: A permit is required for this source because uncontrolled VOC emissions from this facility exceed two tons per year in a nonattainment area for ozone. This source is subject to Section II1.D.2 (Minor Source RACT) because it is located in a nonattainment area. RACT for this source has been determined to be the use of a flare to control emissions. • Is public comment required?
