If yes, are the uncontrolled actual or requested emissions estimated to be greater than or equal to 80 tons VOC per year? If yes, the permit will contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 05-01. 11 Does the company use a site specific emissions factor to estimate emissions? If yes and if there are flash emissions, are the emissions factors based on a pressurized liquid sample drawn at the facility being permitted? This sample should be considered representative which generally means site -specific and collected within one year of the application received date. However, if the facility has not been modified (e.g., no new wells brought on-line), then it may be appropriate to use an older site -specific sample. If no, the permit will contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 05-01. Does the company request a control device efficiency greater than 95% for a flare or combustion device? ^.3' If yes, the permit will contain and initial compliance test condition to demonstrate the destruction efficiency of the combustion device based on inlet and outlet concentration sampling Section 08 - Technical Analysis Notes Applicant used ProMax to modelflash and W/8 emissions, based on a model condensate throughput of 50.5368.sgpm (632432'. bbl/yr model throughput to arrive at the Ib/bbl emissionfactorsentered above, which match the APES, Section 09 - Inventory SCC Coding and Emissions Factors AIRS Point 001 Process ft SCC Code O1 �r The Pr modeled e n flow rates were divided by the:: Uncontrolled Emissions Pollutant Factor Control % Units NOx 0.2711 0 Ib/1,000 gallons condensate throughput VOC 66.9073 95 lb/1,000 gallons condensate throughput CO 0.5413 0 Ib/1,000 gallons condensate throughput Benzene 0.1493 95 lb/1,000 gallons condensate throughput Toluene 0.2017 95 Ib/1,000 gallons condensate throughput Ethylbenzene 0.0069 95 Ib/1,000 gallons condensate throughput Xylene 0.0849 95 lb/1,000 gallons condensate throughput n -Hexane 1.3372 95 lb/1,000 gallons condensate throughput 224 TMP 0.0104 95 lb/1,000 gallons condensate throughput 3 of 3 K:\PA\2017\ 17WE0498.CP1.xlsm W L O 2 c a w 0 a Schnieder Sec. 19 HZ Pad m E r c 0.

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 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 - APEN and Permitting Requirements Is this site considered an exploration and production location (e.g. well pad)? Yes If yes, review the following two exemptions for applicability: Does the operator unload less than 10,000 gallons (238 BBLs( per day of crude oil on an annual average basis? If yes, this emissions point is categorically exempt from permit requirements per Regulation 3, Part B, Section 11.0.1.1 Does this operator unload less than 6,750 bbls per year of condensate via splash fill or 16,308 bbls per year of condensate via submerged fill procedure? If yes, this emissions point is categorically exempt from permit requirements per Regulation 3, Part B, Section 11.0.1.1 No No 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 exceed 1 ton per year VOC) Part B — Construction Permit Exemptions Applicant is required to obtain a permit since uncontrolled VOC emissions from this facility are greater than the 2.0 TPY threshold (Reg. 3, Part B, Section II.D.2.a). PartB, III.D.2 - RACT requirements for new or modified minor sources This section of Regulation 3 requires RACT for new or modified minor sources located in nonattainment or attainment/maintenance areas. This source is located in the 8 -hour ozone nonattainment area, but not the 1 -hour ozone area. The date of interest for determining whether the source is new or modified is therefore November 20, 2007 (the date of the 8 -hour ozone NA area designation). Since the tank battery from which loadout is occurring came into service after the date above (Reported as 07/02/14 on condensate tank APEN), this source is considered "new or modified." Operator is using submerged fill (0.6 saturation factor), therefore, RACT requirements are satisfied. Regulation 7 — Volatile Organic Compounds No sections apply. Per Regulation 7, Section VI.C, a terminal is defined as a petroleum liquid storage and distribution facility that has a daily average throughput of more than 76,000 liters of gasoline (20,000 gallons), which is loaded directly into transport vehicles. This facility is neither a terminal, nor a bulk plant per definitions in Reg 7, Section VI.C. Regulation 8 — Hazardous Air Pollutants MACT EEEE: Not subject because facility is classified as a synthetic minor source of HAPs It should also be noted that the loadout operation is located at a production field facility and thus would be exempt per 40CFR 63.2334(c)(1). HAP emission factorss were estimated by multiplying the HAP/VOC mass fraction ratio by the VOC loading loss equation. The NOx and CO emissions associated with the loadout operation were determined using emission factors from TNRCC Table 4.
