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: EOG Resources, Inc. proposes to construct and operate an oil and natural gas production facility in Weld County, Colorado called Critter Creek 15-19H & 23-19H. This source will consist of twelve (12)- 400BBL crude oil storage tanks, two (2) produced water storage tanks, two (2) emergency tanks , one flare stack, and truck loading for the crude oil. This source will be located in the SESE quarter-quarter of Section 19, Township 11 North, Range 63 West in Weld County, Colorado. These sources would be considered major sources of air pollutants subject to Prevention of Significant Deterioration (PSD) and Maximum Achievable Control Technology (MACT) requirements if the operator did not install emissions controls and accept Federally enforceable emissions limits in the proposed permit. Since the operator will accept emissions limits less than 100 tons per year for each criteria pollutant and less than 10 tons per year any single hazardous air pollutant (HAP) and 25 tons per year total combined HAP, each source will be considered a synthetic minor source not subject to PSD and MACT review. Each source will have permitted emissions less than 100 tons per year for criteria pollutants and will be considered a new synthetic minor source not subject to Title V Operating Permit requirements. As such, this permit is subject to public comment per Regulation 3, Part B, Section III.C.1.d. Copies of the draft permit and preliminary analysis are available for review in the public comment package. The Division has determined that the proposed source will comply with all applicable regulations and standards of the Colorado Air Quality Control Commission and has made a preliminary determination of approval of the application. The Division hereby solicits and requests submission of public comment concerning the aforesaid proposed project and activities 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: Adam Reed Colorado Department of Public Health and Environment 4300 Cherry Creek Drive South, APCD-SS-B1 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.

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, 001-005 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 001-005 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: • each individual emission point in an attainment area with uncontrolled actual emissions of 001-005 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 for these points because uncontrolled emissions exceed 2 tons per year VOC) Part B—Construction Permit Exemptions 001-005 Applicant is required to obtain a permit for points 001-005 since uncontrolled VOC emissions from this facility are greater than the 5.0 TPY threshold(Reg. 3, Part B, Section ll.D.3.a) Part B, III.D.2 - RACT requirements for new or modified minor sources located in ozone 001-005 non-attainment areas This source is not subject to this requirement because it is located in an ozone attainment area. • Regulation 6 - New Source Performance Standards Page 5 001, 002, NSPS Kb: for storage vessels greater than 19,800 gallons after 7/23/84. 003 These tanks are not subject to NSPS Kb because they each have a capacity less than 471 BBL.

Tank emissions controlled by Cimarron smokeless combustor. Without emission controls and federally enforceable emission limits for this point, this facility would be considered a major source of VOC for Operating Permit applicability. In order to obtain synthetic minor limits and avoid Operating Permit applicability, EOG will not take advantage of the categorical permit exemption in Regulation 3, Part B, Section II.D.1.n for crude oil storage tanks with capacities less than 40,000 gallons. AIRS Point 002 Produced Water Storage Tanks EOG used the state default emission factors to calculate emissions from this produced water storage tank battery. Produced water contains less than 1% oil, emissions controlled by Cimarron smokeless combustor. Without emission controls and federally enforceable emission limits for this point, this facility would be considered a major source of VOC for Operating Permit applicability. In order to obtain synthetic minor limits and avoid Operating Permit applicability, EOG will not take advantage of the categorical permit exemption in Regulation 3, Part B, Section II.D.1.m for tanks used to store produced water that is less than 1% oil by volume. Page 7 AIRS Point 003 Emergency Tank In case of a flare outage (AIRS point 004), produced natural gas from this site will be routed to this Emergency Tank. Entrained liquids settle in the tank and the gas will be vented to atmosphere. EOG based emissions from this activity on a gas flow rate of 10,416.7 scf/hr and three venting events per year at 12 hours per event. The composition of the vented gas has the same basis as was used to calculate emissions routed to the flare (point 004). AIRS Point 004 Tornado Flare Emissions calculated using VOC wt. fraction from analysis dated August 9, 2010 from Critter Creek 2- 03H The tornado flare is controlling gas coming off the well since there is no midstream pipeline available in the area at this time. EOG will continue to flare gas until a pipeline is available.
