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. Requlation 2 — Odor 001, 003 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. Re.ulation 3 - APENs, Construction Permits, O.eratinq Permits, PSD 001, 003 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 nonattainment. (Applicant is required to file an APEN since emissions from condensate production are greater than 1 ton per year VOC) 001, 003 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 ll.D.2.a) Re.ulation 6 - New Source Performance Standards Page 4 001 NSPS Kb: for storage vessels greater than 19,800 gallons after 7/23/84.

I was hoping you can help me with this piece of information. Paul Buck with Encana called back on 12/19/12 providing information on the total tank capacity. He said that there was one 100 -BBL and ten 330 -BBL tanks onsite. I quickly emailed him asking him to confirm the year the tanks were in place. These sources are emitting a lot of emissions and I want to make sure before I grant them GF status, that they meet it. APEN says that the source was in place in 2000, which is prior to December 30, 2002. He wrote back on 12/19/12: No, the 2000 is incorrect- the 10 330s were associated with the new wells were put in service in 2012. The one tank associated with the 100 bbl tank is associated has been in service since 1985. Therefore, this source has been modified and lost its grandfather status, therefore, will require a permit. Operator provided site -specific emission factors using an extended gas analysis dated 7/11/12 and E&P tanks. The emission factors are: VOC = (1056.732 *2000)/91781 = 23.027 lb/bbl* 1000/42 = 548.268 lb/1000 gal Benzene = (2.623*2000)/91781 = 0.057 lb/bbl * 1000/42 = 1.361 lb/1000 gal Toluene = (1.858*2000)/91781 = 0.040 lb/bbl * 1000/42 = 0.964 lb/1000 gal Ethylbenzene = (0.165*2000)/91781 = 0.004 lb/bbl * 1000/42 = 0.086 lb/1000 gal Xylenes = (0.595*2000)/91781 = 0.013 lb/bbl * 1000/42 = 0.309 lb/1000 gal n -hexane = (15.853*2000)/91781 = 0.345 lb/bbl * 1000/42 = 8.225 lb/1000 gal 12/19/12: I had a few questions for the operator regarding the O&M plan: 1. Section 2: Both boxes have been checked. I typically see only one box checked. Is this correct? If not, which one should it be? Paul Buck called on 12/19/12 and said that the second box should be checked, not the first. I redlined the O&M and made sure the correct information was added in CACTIS. 2. Section 4: Backup method was checked for "Other" however there were no attachments to the O&M plan. Should backup just be the tank level measurements? Paul Buck called on 12/19/12 and said to remove the "other." I redlined the O&M and made sure the correct information was added in CACTIS.

I tried several times, and did not get what they calculated. Paul Buck called on 12/19/12 saying that those numbers are assumed numbers that Encana has seen over several applications. However, he noticed that the molecular weight should not be 109 Ib/Ib-mol (that is for the oil) and it should be 66 lb/lb-mol (for the vapors). He provided me supporting documentation via email on 12/19/12. I reviewed it and made the changes to the APEN, PA and permit. Emission factors are calculated as multiplying the VOC emission factor (generated from AP -42) with the wt % of VOC (which is an assumed engineering calculation done by Encana): VOC E.F. = 7.91 lb/1000 gal Benzene = (7.91 lb/1000 gal) * .0094 = 0.0744 lb/1000 gal Toluene = (7.91 lb/1000 gal) * .0166 = 0.1313 lb/1000 gal Ethylbenzene = (7.91 lb/1000 gal) * .0007 = 0.0055 lb/1000 gal Xylenes = (7.91 lb/1000 gal) * .0073 = 0.0577 lb/1000 gal n -hexane = (7.91 lb/1000 gal) * .0094 = 0.1843 lb/1000 gal Page 7 123-99E9-001-APEN-2012-08-03-01 Pollutant'° VOC [tons/year] NOx [tons/year] CO [tons/year] Benzene [lbs/year] n -Hexane [lbs/year] Air Pollutant Emission Notice (APEN) — and — Application for Construction Permit OIL AND GAS EXPLORATION AND PRODUCTION CONDENSATE STORAGE TANK BATTERY Current Status (Check all that apply) [ 23RgEq I0D AIRS ID #1: ® New or previously unreported battery , ❑ Previously grandfathered battery' ❑ Synthetic minor facility ® Located in the 8 -hr Ozone Control Area3 I' ❑ Registered under general permit no.
