Therefore, the Air Pollution Control Division of the Colorado Department of Public Health and Environment hereby gives NOTICE, pursuant to Section 25-7- 114.5(5), C.R.S. of the Colorado Air Quality Control Act that the Division received an application for an air pollution emission permit on the following proposed project and activity: Carizzo Oil & Gas, Inc. proposes to operate four(4) crude oil tanks at and natural gas exploration and production site located in Section 1, Township 9 North, and Range 59 West in Weld County. The facility has the potential to emit(PTE) of 807 tons of volatile organic components (VOC) per year. The draft permit has limitations that will reduce emissions to 44 tons per year of VOC. Since this source has the potential to emit greater than 250 tons per year of VOC, but is willing to accept limits to bring the emissions below 100 tons per year, this source is considered to be a synthetic minor source for Prevention of Significant Deterioration (PSD) and Title V, as such, this permit is subject to public comment per Regulation 3, Part B, Section III.C.I. The Division hereby solicits and requests submission of public comment from any interested person concerning the aforesaid proposed project and activities to comply with the applicable standards and regulations of the Commission for a period of thirty (30) days from the date of this publication. Any such comment must be submitted in writing to the following addressee: Stephanie Chaousy, P.E. Colorado Department of Public Health and Environment 4300 Cherry Creek Drive South, APCD-SS-B I Denver, Colorado 80246-1530 Within thirty(30)days following the said thirty(30)-day period for public comment, the Division shall consider comments and, pursuant to Section 25-7-114.5(7)(a), either grant, deny, or grant with conditions, the emission permits. Said public comment is solicited to enable consideration of approval of and objections to the proposed construction of the subject project and activity by affected persons. A copy of the applications for the emission permits, the preliminary analysis of said applications, and accompanying data concerning the proposed project and activity are available for inspection at the office of the Clerk and Recorder of Weld County during regular business hours and at the office of the Air Pollution Control Division, Colorado Department of Public Health and Environment, 4300 Cherry Creek Drive South, Denver, Colorado. A copy of the draft permit and preliminary analysis are available on the Air Pollution Control Division's website at: http://www.colorado.gov/cs/Satellite/CDPHE-AP/CBON/1251596498449 Construction Permit Application Preliminary Analysis Summary Section 1 —Applicant Information Company Name: Carrizo Oil & Gas, Inc.

AIRS Point Section 12— Regulatory Review Regulation 1 - Particulate, Smoke, Carbon Monoxide and Sulfur Dioxide Section II.A.1 - Except as provided in paragraphs 2 through 6 below, no owner or operator of a source shall allow or cause the emission into the atmosphere of any air pollutant which is in excess of 20% opacity. 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, 001 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 001 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: 001 each individual emission point in an attainment area with uncontrolled actual emissions of two tons per year or more of any individual criteria pollutant (pollutants are not summed) for which the area is attainment. (Applicant is required to file an APEN since emissions exceed 2 tons per year VOC) Part B—Construction Permit Exemptions 001 Applicant is required to obtain a permit since TOTAL FACILITY uncontrolled VOC emissions from this facility are greater than the 5.0 TPY threshold(Reg. 3, Part B, Section II.D.2.a) Regulation 6 - New Source Performance Standards Page 3 NSPS Kb: for storage vessels greater than 19,800 gallons after 7/23/84. Is this source greater than 19,800 gallons (471 bbl)? No 001 Is this source subject to NSPS Kb? No WHY? Source contains 4-400 bbl, which is less than the threshold per requirement(400 < 471). Therefore, not subject to NSPS Kb. Regulation 7—Volatile Organic Compounds 001 None Regulation 8—Hazardous Air Pollutants 001 None Section 13—Aerometric Information Retrieval System Coding Information Point Process Process Emission Pollutant/ Fugitive Control Description Factor CAS# (Y/N) Emission Factor Source (%) 326.1905 V0C No CDPHE Memo 05-02 95 lb/1000 gal 01 E&P Crude oil 0.5714 Benzene/ No CDPHE Memo 05-02 95 001 Storage Tanks lb/1000 gal 71432 5.0 n-Hexane No CDPHE Memo 05-02 95 lb/1000 gal /110543 SCC 40400312—Fixed Roof Tank, Crude oil, working+breathing+flashing losses Section 14—Miscellaneous Application Notes AIRS Point 001 Crude Oil Storage Tanks A permit will be issued because the uncontrolled VOC emissions are greater than 5 TPY (permit threshold). Operator used the State condensate tank emission factors (conservative) for VOC and HAPS. The VOC emission factor of: VOC = 13.7 lb/bbl Meeting a 39 TPY controlled emission limit, the uncontrolled VOC is calculated backwards at: (39'100)/5 = 780 TPY So, the requested throughput is calculated at: (780'2000)/13.7 = 113,869 BBL/yr I will not redline the APEN because the APEN is listing actual emissions, and for inventory purposes, the actual emissions should be listed on the APEN for billing purposes. I emailed Carizzo on 9/6/12 regarding the Ajax engine they have onsite. Operator listed source as APEN-exempt/permit-exempt, although the formaldehyde is greater than 50 lb/yr. I believe the source will require an APEN.
