This standard is based on 24 consecutive opacity readings taken at 15-second intervals for six minutes. The approved reference test method for visible 003 and emissions measurement is EPA Method 9 (40 CFR, Part 60, Appendix A(July, 1992)) in all 005 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 Page 4 Section LA-No person, wherever located, shall cause or allow the emission of odorous air 003 and contaminants from any single source such as to result in detectable odors which are 005 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 Part A-APEN Requirements Criteria Pollutants: For criteria pollutants, Air Pollutant Emission Notices are required for: 003 and each individual emission point in a non-attainment area with uncontrolled actual emissions of 005 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) 003 and Part B—Construction Permit Exemptions 005 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) Part B, 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. 003 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, this source is considered "new or modified." The installation date of the most recent storage vessel in the storage tank is reported as 06/2014 on the APEN. Operator is using submerged fill (0.6 saturation factor), therefore, RACT requirements are satisfied. Regulation 6-New Source Performance Standards 003 No applicable subpart. This facility is not a bulk gasoline terminal. 005 No applicable subpart. Re.ulation 7—Volatile Or.anic Corn.ounds 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 003 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. Was the well newly constructed, hydraulically fractured, or recompleted on or after August 1, 2014? Yes, The cover letter expressed that the four wells began producing on September 005 24, 2014.

Application Notes: 1. The operator calculated the HAP emission factors by multiplying the VOC emission determined with AP-42, Chapter 5.2, Equation 1 by the ratio of the HAP wt fraction found in the liquids analysis to the VOC weight fraction in the liquids analysis. Equation: HAP EF, lb/bbl = (VOC EF, Ib/bbl)*((HAP wt fraction in liquid)/(VOC wt. fraction in liquid)) Page 7 Heated Separator and four(4)vapor recovery towers(VRTs)to reduce flash emissions. Emissions are a function of condensate throughput during VRU AIRS Point 005 bypass. 25%VRU bypass is assumed. The heated separator and VRTs are controlled by five(5)enclosed combustors during VRU bypass. Flares have a minimum control efficiency of 95%. A permit will be issued because the uncontrolled VOC emissions are greater than 1 TPY(APEN threshold)and greater than 2 TPY(permit threshold). The operator utilized site specific emission factors. The site specific liquid analysis provided in the application was utilized as an input for a Pro-Max simulation (i.e. mole% of each component of liquid stream). The Pro-Max simulation was run using a basis production rate of 1 barrel/day. The output of the Pro-Max simulation resulted in rates of flash gas from the heated separator and VRT gas reported in (lb/hr). These outputs were summed and served as the basis for the emission factors reported on the APEN. The emissions from ProMax are as follow: Pollutant Pro-Max Heated Separator Flash Pro-Max VRT Gas Stream Gas Stream Rate Rate(lb/hr) (lb/hr) VOC 0.614792256 0.001117567 Benzene 0.00315125 0.00000348636 n-Hexane 0.0164528 0.0000176873 Toluene 0.00261110 0.00000227055 Xylenes 0.000854649 0.000000552104 Ethylbenzene 0.000448052 0.000000304968 2,2,4-Trimethylpentane 0.00224600 0.00000205376 The calculations used to determine the emission factors in lb/bbl as reported on the APEN are as follow: Given Information: • Requested Throughput(based on 25% of condensate throughput) =60,750 bbl/year(166.4 bbl/day). This throughput is based on the estimated 25%downtime of the VRU, which typically routes the flash gas to a sales pipeline. Calculation: \ 1 day/ EF(lb/bbl) = (Separator RateProMax,vRT+VRT Rate ProMax,Heated Separator) *(1 bbl/ *24hrs/day Example Calculation for VOC: EFvoc = (0.001 7567 lb+0.6147 256 lbl * (1 day\ bbl/ * ( day bbl 2s) _ 14. Lb hr hr )**Actual and requested emissions reported on the APEN were calculated by multiplying the emission factors(lb/bbl) by the actual and requested throughputs. **The above calculation was repeated for the HAPs to determine the emission factors. A natural gas liquid analysis from the Anschutz 4-62-9-1609CH2 well was provided in the application dated 10/20/2014(sample date). The liquid analysis was performed within less than a year of submittal of the permit application.An updated extended liquid analysis will not be required because: -an extended liquid analysis was performed within a year of this submittal and included with this package. The NOx and CO emissions were calculated through the following method: Given information: Heating Value(Btu/scf) Throughput(MMscf/day) Separator 2663.14 0.000138807 VRT 2334.48 0.000000321436 *The heating value and throughput were obtained from the appropriate streams in ProMax Page 8 **The ga s as was also taken into consideration in the determination of the NOx and CO emissions. The P pilot gas throughput per ECD was given as 50scf/hr. Since there are five (5) ECDs at the location the total throughput was determined to be 250 scf/hr. This was converted to a value of 2,878 MMBtu/yr using the field gas heating value of 1314.2 btu/scf. The pilot gas was then weighted based on the four sources controlled by the ECDs (water tanks, condensate tanks, separator, and VRT). The apportioned pilot gas for the VRT was determined to be 4.80 MMBtu/yr while the apportioned pilot gas for the separator was determined to be 2365.35 MMBtu/yr. The following throughput separator was conducted to convert the throu h ut of the se arator and VRT to units of MMBtu/yr: (0.000138807 MMscf (1.0x106scf\ lday (60,750 bbl (2663.14 Btu MMBtu p Separator r day /l* \ MMscf /I*( l* l* l*( \lbbl/ l year ) l scf ) \1.0x106Btu 22,456.9MMBtu yr 0.000000321436 MMscf\ (1.0x106scf\ (1day)*/60,750 bbl\* /2334.48 Btu\ ( MMBtu VRT= ( day /*I\ MMscf /I*\1bb1/ \ year / l scf /* \1.0x106Btu/ 45.6MMBtu yr The separator and VRT values calculated above were then summed with the apportioned pilot gas and then multiplied by the appropriate emission factor to determine the NOx and CO emissions. A sample calculation is as follows: 22,456.9MMBtu 45.6MMBtu 2365.35MMBtu 4.80MMBtuI (0.0681bN0x) ( lton NOx= ( + + + *\ *\20001bs1 = 0.846tpy yr yr yr yr / MMBtu ) This calculation was repeated to determine the CO emissions as well. Notes: 1. In the original submission, the ProMax simulation did not result in flash emissions from the condensate tanks. This discrepancy was discussed with the operator. The operator agreed that this result from the simulation was not expected, and that flash emissions from the condensate tanks would be expected in the field. As a result, a new sample was utilized to run a new ProMax simulation. This simulation did result in flash emissions at the condensate tanks and was utilized for the analysis of the VRU bypass. This information was received from the operator on May 15, 2015. The updated ProMax simulation result was utilized to update the calculations for the VRU bypass (Point 005) and condensate loadout(point 003). 2. The operator was provided with a draft permit to review prior to public comment. They reviewed the draft and expressed they did not have any comments. • Page 9 O b 0 (� y ,� O O O O O y, ° E O ° C ,� .-. +� O M m m Y.
