(vii) Component leaks detected shall be repaired as set forth below: a. The leak will be repaired within 15 days. Repaired components shall be re-screened within five days of repair to determine if the leak is repaired. If the rescreening shows a leak, then the leak shall be repaired as soon as practicable, but no later than 15 days after the rescreening. Repeat the process until the rescreening shows no leak.

Section 25-7-114.7(2)(a), C.R.S. requires that all sources required to file an Air Pollution Emission Notice (APEN) must pay an annual fee to cover the costs of inspections and administration. If a source or activity is to be discontinued, the owner must notify the Division in writing requesting a cancellation of the permit. Upon notification, annual fee billing will terminate. 38. Violation of the terms of a permit or of the provisions of the Colorado Air Pollution Prevention and Control Act or the regulations of the AQCC may result in administrative, civil or criminal enforcement actions under Sections 25-7-115 (enforcement), -121 (injunctions), -122 (civil penalties), -122.1 (criminal penalties), C.R.S.

This standard is based on 24 consecutive opacity readings taken at 15-second intervals for six minutes. The approved reference test method for 001-004, visible emissions measurement is EPA Method 9 (40 CFR, Part 60, Appendix A(July, 009, 010 1992)) in all subsections of Section II. A and B of this regulation.

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 All 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: All 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 All 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 will be in service after the date above, this source is considered "new or modified." Operator is using submerged fill (0.6 saturation factor), therefore, RACT requirements are satisfied. 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. 005 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 fugitives will be in service after the date above, this source is considered "new or modified." Operator has agreed on the Division's standard conditions. Regulation 6-New Source Performance Standards NSPS Kb: for storage vessels greater than 19,800 gallons after 7/23/84. Is this source greater than 19,800 gallons (471 bbl)?Yes 002 Is this source subject to NSPS Kb? No WHY? The storage tanks at the facility are all prior to custody transfer and are therefore not subject to this subpart. 003 No applicable subpart. This facility is not a bulk gasoline terminal. Page 7 NSPS OOOO: Standards of Performance for Crude Oil and Natural Gas Production, Transmission and Distribution. For fugitive emissions at natural gas processing plants subject to NSPS OOOO. This subpart establishes emission standards and compliance schedules for the control of volatile organic compounds(VOC)and 005 sulfur dioxide(SO2 )emissions from affected facilities that commence construction, modification or reconstruction after August 23, 2011. Is this source at a"natural gas processing plant?" No Is this source subject to NSPS OOOO? No WHY? Source is not located at a"natural gas processing plant" but a production field facility,therefore, not meeting the requirements of this subpart. Regulation 7—Volatile Ora tomoounds XII. VOLATILE ORGANIC COMPOUND EMISSIONS FROM OIL AND GAS OPERATIONS (Applicant is subject to the emission control requirements for condensate tanks 001, 009, since it is located in a non-attainment area.) 010 XVII.C STATEWIDE CONTROLS FOR OIL AND GAS OPERATIONS... (Applicant is currently subject to this since actual uncontrolled emissions are greater than 20 tpy of VOC.) 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 003 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. Section XII.G: If facility Is a natural gas processing plant located In non-attainment area,then subject to Section XII.G. 008 This facility is not a natural gas processing plant,therefore, not subject to this subpart. B puiatio 8-Hazardous_Aif Pamtanta 001,002, MACT EEEE: Organic Liquids Distribution 009, 010 This source is not subject to MACT EEEE because it is not located at a major source of HAP. 001 MACT HH This source is not subject to MACT HH because it is not located at a major source of HAP. MACT HH: If facility is MAJOR source for HAP at a natural gas processing plant ONLY(summation of HAPS of dehydrators and fugitives),then fugitive emissions are subject to MACT HH. 005 Is this facility considered MAJOR for HAPS? No Is this source subject to MACT HH? No WHY? This facility is considered area source for MACT HH; therefore, only TEG dehydrators at this facility would be subject(there are no dehys onsite).

Source provided site-specific emission factors using EPA Tanks(working and breathing)and WimSim(flashing). Emission factors were generated from both models and then added together. The Winsim showed no flashing emissions, and E&P tanks agreed. The liquid analysis used in WimSim had a sample date of 24 2013(less P July than 1 year of application submittal).

None of the well names match any stated wells associated with this site, and seem to belong to"Econode B12", according to my understanding of the nomenclature used by Noble. An updated extended gas analysis will be required because the tests included in the application were not extended gas analyses and not site-specific. The HAP composition was assumed conservatively high using values from surrounding facilities. AIRS Point 005 Fugitive VOC Leak Emissions A permit will be issued because the uncontrolled VOC emissions are greater than 2 (permit threshold). AIRS Point 009 Condensate Storage Tanks A permit will be issued because the uncontrolled VOC emissions are greater than 2 TPY(permit threshold). This point was converted from a GP01, and uses state emission factors for condensate tanks. Originally, a slightly lower emission factor than the state was used for the VOC emissions—12.89 lb/BBL. In light of no sampling documentation being presented, I am redlining and changing to 13.7 lb/BBL. AIRS Point 010 Condensate Storage Tanks A permit will be issued because the uncontrolled VOC emissions are greater than 2 TPY(permit threshold). This point was converted from a GP01, and uses state emission factors for condensate tanks.
