If yes, the permit will contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 14-03. Does the company use a site specific emissions factor to estimate emissions? If yes and,ifthere are flash emissions, are the emissions factors based on a pressurized liquid sample drawn at the facility being permitted (for produced water tanks, a pressurize liquid sample must be analyzed using flash liberation analysis)? This sample should be considered representative which generally means site -specific and collected within one year of the application received date. However, if the facility has not been modified (e.g-, no new wells brought on-line), then it may be appropriate to. use an older site -specific sample. If no, thepermitwill contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 14-03.

If yes, are the uncontrolled actual or requested emissions for a crude oil tank estimated to be greater than or equal to 20 tons VOC per year OR are the uncontrolled actual or requested emissions for a condensate storage tank estimated to be greater than or equal to 80 tpy? If yes, the permit will contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS. Memo 14-03. Does the company use a site specific emissions factor to estimate emissions? If yes and if there are flash emissions, are the emissions factors based on a pressurized liquid sample drawn at the facility being permitted (for produced water tanks, a pressurize liquid sample must be analyzed using flash liberation analysis)? This sample should be considered representative which generally means site -specific and collected within one year of the application received date. However, if the facility has not been modified (e.g„ no new wells brought on-line), then it may be appropriate to use an older site -specific sample. If no, the permit will contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 1403. Does the company request a control device efficiency greater than 95% for a flare or combustion device? If yes, the permit will contain initial and periodic compliance testing in accordance with PS Memo 20-02 Section 08 -Technical Analysis Notes Applicant estimated flash/working/breathing emissions using Pro based on a site-specificpreSsunzed lipoid sample and gas sample collected 2112/19..

Date of first production of well API#05.123-38068 was 1/14/2015, which is after August 1, 2014, and so the separators covered by this point are subject to Regulation 7, Part D, Section II.F. L The extended gas analysis used to establish emission factors in this application was obtained from the outlet of the buffer house (liquids knockout for low pressure gas vented from the low pressure side of the HLP separators) at this facility. As a result, rt rs representative of only low pressure gars that is vented to and controlled by the enclosed combustors. 3. During normal operations, low pressure gas vented from the low pressure side of the HLP separators is captured using vapor recovery units (VRUs) and routed to the sales line. During VRU downtime, the low pressure gas is routed through the buffer house (liquids knockout) and then to the enclosed combustors. VRU downtime tracking is required in the permit to quantify the volume of gas vented frorn the separators and routed to the enclosed combustor(s), based on the liquids throughput to the storage tanks. 4 It should be noted that an emission factor for VOC associated with pilot light combustion is not incorporated into the permit. This is due to the fact that the pilot light only results in a negligible contribution of VOC. This minimal amount of emissions does not impact the total VOC limit for this source and therefore can be ignored.

The high pressure gas from the high pressure side of the HLP separators is routed to the sales line via vapor recovery units. The low pressure gas from the) wpressure side of the HLP separators - is typically routed through a buffer house (liquids knockout) and then to the sales lime vla vapor recovery units. During vapor recovery unit downtime;. the low pressure gas: vented from the low pressure side of the HLP separators Is routed through. a buffer house (liquids knockout) and then to the enclosed cambustor(s). In order to develop site specific emission factors, the operator used a dte-specific safes gas sample and a pressurreed lipid sample collected an 2/12/19.

During normal operatons, low pressure gas vented from the low pressure side of the HLP separators is captured using vapor recovery unts(VRUs) and routed to the sales the During VRU downtime, the low pressure gas is routed through the buffer house (liquids knockout) and then to the enclosed cpmbustors.VRU downtime tracking s required In the permit to quantify the volume of gas vented from the separators and routed to the enclosed combustor(s), based an the liquids throughpuitothe storage tanks. 4. It should be noted that an emission factor for VOC associated with pilot light combustion is not incorporated into the permit. This is due to the fact that the pilot light only results in a negligible contribution of VOC. This minimal amount of emissions does not impactthe total VOC limit for this source and therefore can be ignored. Section 09 -SCC Coding and Emissions Factors (For Inventory Use Only].

The eight (8) wells on site each produce through high/low pressure separators. • Hydrocarbon liquids from the high/low pressure separators are sent to the condensate storage tanks. Produced water from the high/low pressure separators is routed directly to water storage tanks. Condensate storage tank emissions are routed to enclosed combustors for control. Condensate is transferred out of the facility either by pipeline or truck. Produced water is transported from the facility via truck. The storage tank battery consists of twenty-eight (28) 500 -barrel condensate storage tanks and four (4) 235 -barrel water storage tanks. • Gas from the low-pressure side of the separators are routed to vapor recovery units (VRU). In the event the VRUs are offline, gas is sent to enclosed combustors for control. • Gas from the high-pressure side of the separators is directed to the sales line via VRU. Crestone is requesting an individual permit for an enclosed process flare at the Edith Ann -Duckworth 21H-0268 Battery to control the low-pressure separator gas when VRUs are unavailable. Figure 1.

When necessary, the regulatory analysis below uses this date for applicability. The regulatory analysis provided here is for the condensate tanks, the proposed enclosed process flare and the facility -wide determinations associated with this modification. 1.0 Federal New Source Review Non -attainment New Source Review Weld County was re -designated as serious non -attainment for ozone on January 27, 2020. Upon re -designation, the Edith Ann -Duckworth 21H -O268 facility remained an existing minor in an ozone non -attainment area with potential facility -wide emissions of ozone precursors, Nitrogen Oxides (NOx) and Volatile Organic Compounds (VOC). With this modification request the Edith Ann -Duckworth 21H -O268 facility will return to an existing synthetic minor source. New Source Review (NSR) applies to new or modified sources with emissions or net emission increases in excess of specified thresholds. Existing minor sources are subject to Non -Attainment New Source Review (NANSR) only if proposed increases in NOx or VOC emissions constitute a major stationary source in and of themselves (Colorado Regulation 3, Part D, Section II.A.25.c.). Under serious non -attainment, the major stationary source threshold is 50 tpy of either NOx or VOC. NANSR is triggered by any modification to an existing major source that increases potential emission of NOx or VOC by 25 tpy or more. The projected change in emissions associated with this permit application indicates an increase of less than 25 tpy of both NOx and VOC, therefore this modification to the Edith Ann -Duckworth 21H - O268 facility is not subject to additional NANSR review under the NSR thresholds. Potential for Significant Deterioration Specific source types are subject to Prevention of Significant Deterioration (PSD) review if their potential to emit (PTE) exceeds 100 tpy of any regulated NSR pollutant. All other source types are subject to PSD review if their PTE exceeds 250 tpy. This facility is not one of the listed source types and does not exceed a PTE of 250 tpy of any regulated NSR pollutant; therefore, this facility is not subject to PSD review. 2.0 Federal Operating Permits Sources are required to obtain a Part 70 Title V Operating Permit if they are a major source of emissions. A major source is defined as a stationary source that emits or has the potential to emit 10 tpy of any single hazardous air pollutant (HAP), 25 tpy of total HAPs, or 100 tpy of any regulated air pollutant. However, the thresholds for NOx and VOC are 50 tpy in a serious non -attainment area. An Exploration & Production well facility is not a listed source type, therefore fugitive emissions are not included in determining major source status. This facility will not emit any pollutant above the specified thresholds and is therefore not required to obtain a Title V operating permit. 3.0 State Regulations Regulation 1, Section II.A.1. Except as provided in paragraphs 2 through 6 of Regulation 1, Section II.A, stationary sources are limited to emissions with a maximum opacity of 20% except during periods of startup and shutdown. Regulation 2, Odor Emission All sources are subject to the general odor emission provisions detailed in Colorado Regulation 2. Regulation 3, Part A, Section II. Regulation 3, Part A, Section II describes when an APEN must be submitted for new, modified, and existing sources. This application proposes the construction of a new stationary source and a modification of an existing stationary emission source, with estimated uncontrolled criteria pollutant emissions greater than one ton per year in a non -attainment area. Therefore, it is subject to the provisions of Regulation 3, Part A. Regulation 3, Part B Regulation 3, Part B describes the requirements for Construction Permits. This application requests a new construction permit be issued. Therefore, it is subject to the provisions of Regulation 3, Part B. Regulation 3, Part C Regulation 3, Part C describes the requirements for Operating Permits. This facility will become an existing synthetic minor source of both criteria pollutant and HAP emissions. Therefore, it is not subject to the provisions of Regulation 3, Part C. Regulation 3, Part D Regulation 3, Part D describes the requirements for new or existing major stationary source New Source Review and Prevention of Significant Deterioration. As described above, the facility is not subject to NSR or PSD review at this time. Regulation 7, Part D, Section I. Regulation 7, Part D, Section I describes requirements for VOC emissions from oil and gas operations located in the ozone non -attainment area. ■ The control equipment (enclosed combustors) used to demonstrate compliance with the requirements under this section must comply with all general requirements under Section I.C. ■ The condensate storage tanks at this facility are subject to the emission control requirements under Section I.D. ■ The condensate storage tanks at this facility are subject to the monitoring requirements under Section I.E. ■ The condensate storage tanks at this facility are subject to the recordkeeping and reporting requirements under Section I.F. Regulation 7, Part D, Section II. Regulation 7, Part D, Section II. describes statewide requirements for control of emissions from oil and gas operations. The following requirements apply under this Section: ■ The control equipment used to demonstrate compliance with the requirements under this section (enclosed combustors) must comply with all general requirements under Section II.B. ■ The condensate storage tanks at this facility are subject to the emission control requirements under Section II.C, including Storage Tank Emission Management System (STEM) plan requirements. ■ The separator venting emissions at this facility will be subject to the emission control requirements of Regulation No. 7, Part D, Section II.F because the gas coming off a separator comes from a well that was newly constructed, hydraulically fractured, or recompleted on or after August 1, 2014. Emissions from this source are controlled via enclosed combustor. There are no further requirements under this section applicable to this source. 4.0 New Source Performance Standards Regulation 6, Part A (40 CFR Part 60), Subpart Kb — Standards of Performance for Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification . Commenced After July 23, 1984 NSPS Subpart Kb applies to storage vessels with a capacity greater than or equal to 75 cubic meters that is used to store volatile organic liquids (VOL) and that was constructed, reconstructed, or modified after July 23, 1984. ■ Condensate Storage Tanks All condensate storage tanks at this facility have maximum volumes of 500 bbl (approximately 79.5 cubic meters) but are used to store condensate prior to custody transfer. Therefore, these tanks are exempt from Subpart Kb requirements per §60.110b(d)(4). Hydrocarbon Liquid Loading APEN Form APCD-208 Air Pollutant Emission Notice (APEN) and Application for Construction Permit All sections of this APEN and application must be completed for both new and existing facilities, including APEN updates. Incomplete APENs will be rejected and will require re -submittal. Your APEN will be rejected if it is filled out incorrectly, is missing information, or locks payment for the filing fee. The re -submittal will require payment for a new filing fee. This APEN is to be used for hydrocarbon liquid loading only. If your emission unit does not fall into this category, there may be a more specific APEN for your source (e.g. amine sweetening unit, glycol dehydration unit, condensate storage tanks, etc.). In addition, the General APEN (Form APCD-200) is available if the specialty APEN options will not satisfy your reporting needs. A list of all available APEN forms can be found on the Air Pollution Control Division (APCD) website. This emission notice is valid for five (5) years. Submission of a revised APEN is required 30 days prior to expiration of the five-year term, or when a reportable change is made (significant emissions increase, increase production, new equipment, change in fuel type, etc.).

Incomplete APENs will be rejected and will require re -submittal. Your APEN will be rejected if it is filled out incorrectly, is missing information, or lacks payment for the filing fee. The re -submittal will require payment for a new filing fee. This APEN is to be used for gas venting only. Gas venting includes emissions from gas/liquid separators, well head casing, pneumatic pumps, blowdown events, among other events. If your emission unit does not fall into this category, there may be a more specific APEN for your source (e.g. amine sweetening unit, hydrocarbon liquid loading, condensate storage tanks, etc.). In addition, the General APEN (Form APCD-2OO) is available if the specialty APEN options will not satisfy your reporting needs. A list of all available APEN forms can be found on the Air Pollution Control Division (APCD) website. This emission notice is valid for five (5) years.
