This standard is based on 24 consecutive opacity readings taken at 15 -second intervals for six minutes. The approved reference test method for visible emissions measurement is EPA Method 9 (40 CFR, Part 60, Appendix A (July, 1992)) in all subsections of Section II. A and B of this regulation. Section II.A.5 - Smokeless Flare or Flares for the Combustion of Waste Gases 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 for a period or periods aggregating more than six minutes in any sixty consecutive minutes. Regulation 2 — Odor 005 Section I.A - 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. Regulation 3 - APENs, Construction Permits, Operating Permits, PSD 005 Part A-APEN Requirements Criteria Pollutants: For criteria pollutants, Air Pollutant Emission Notices are required for: each individual emission point in a non -attainment area with uncontrolled actual emissions of one ton per year or more of any individual criteria pollutant (pollutants are not summed) for which the area is non -attainment. (Applicant is required to file an APEN since emissions from production exceed 1 ton per year VOC) 005 Part B — Construction Permit Exemptions Applicant is required to file a permit since uncontrolled VOC emissions are greater than the 2.0 TPY threshold (Reg. 3, Part B, Section ll.D.2.a) Regulation 6 - New Source Performance Standards 005 None Page 3 ,Regulation 7 — Volatile Organic Compounds 005 None Regulation 8 — Hazardous Air Pollutants 005 None Section 13 — Aerometric Information Retrieval System Coding Information Point Process Process Description Emission Factor Pollutant / CAS # Fugitive (Y/N) Emission Factor Source Control (%) 005 01 Flare 35262.4838 Ib/MMSCF VOC No Engineering Calculation 95 0.068 lb/MMBtu NOx No AP -42, Table 13.5-1 NA 0.37 lb/MMBtu CO No AP -42, Table 13.5-1 NA 83.8914 Ib/MMSCF Benzene No Engineering Calculation 95 617.3580 lb/MMSCF n -hexane No Engineering Calculation 95 SCC 31000205 -Flares Section 14 — Miscellaneous Application Notes AIRS Point 005 Process flare A permit will be issued because the uncontrolled VOC emissions are greater than 2 TPY (permit threshold).
