Controlled emissions are based on a enclosed combustion device control efficiency of 95%. Total actual flash tank and still vent combustion emissions are based on the sum of the emissions for the still vent primary control, still vent secondary control, flash tank primary control and flash tank secondary control. Total combustion emissions are based on the following emission factors: Page 12 of 14 COLORADO Air Pollution Control Division Department of Public Health 6 Environment Dedicated to protecting and improving the health and environment of the people of Colorado Still Vent Primary Control (Enclosed Combustion Device) CAS # Pollutant Uncontrolled Emission Factors lb/MMscf Waste Gas Combusted Source PKO 1.5 AP -42 Table 1-4-2 PM2.s 1.5 SOx 0.1 NOx 12.8 TNRCC RG-109 Table 4 CO 109.9 Note: The combustion emission factors are based on a heating value of 200 Btu/scf. Actual emissions are calculated by multiplying the emission factors in the table above by the waste gas flow from the regenerator overheads stream in the monthly GlyCalc report and by the hours per month the waste gas was routed to this control device. Still Vent Secondary Control: When the enclosed combustion device is down, still vent emissions are sent to the VRU. Flash Tank Primary Control: Flash tank emissions are recovered using a vapor recovery unit. Flash Tank Secondary Control: Flash tank emissions are sent to the facility inlet using a closed -loop system when the VRU is down. 6) In accordance with C.R.S. 25-7-114.1, each Air Pollutant Emission Notice (APEN) associated with this permit is valid for a term of five years from the date it was received by the Division.

The operator does not use those tanks for routine operations a though they remain permitted under GP01. They track throughput and have not had condensate in the tanks for 6+ years, so actual emissions have remained at 0 as shown in the 2019 APEN renewal. If they ever need to operate them routinely (above the 2 tpy Reg 7 th eshold for controls) they will complete the required paperwork updates and install any required controls at that time.

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 glycol dehydration (dehy) units 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, hydrocarbon liquid loading, 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.).

Process Description Gas enters the compressor station where it is routed to an inlet separator slug catcher. The inlet separator slug catcher separates gas from any hydrocarbon/water condensate. The vapor exiting the inlet separator is then routed through a station inlet meter and then into the compressors suction header. From the compressors suction header gas is compressed by five Cat35166/Ariel JGT4 compressors. Gas is discharged from each compressor into a common discharge header. From there it is routed through a gas/condensate heat exchanger where heat is passed from the discharged gas to the hydrocarbon/water condensate gathered from the inlet separator slug catcher and all separators located on the individual compressor skids. The gas exits the heat exchanger and is then passed to the TEG (Tri-ethylene glycol) dehydration absorber. In the absorber the gas is in contact with TEG which allows the gas stream to be dehydrated to a water content of 7lb H2O/ mmscfd or less. Gas is then passed through filtration and then exits the facility. TEG is regenerated by removing absorbed water by use of a direct fired reboiler. Water vapor and small amounts of hydrocarbon vapor released from the TEG regeneration skid are routed to a small condenser where the majority of hydrocarbon vapors and some water are condensed and then pumped back into the hydrocarbon/water condensate header system. Any hydrocarbon and water vapor that is not condensed is routed to a VRU compressor which discharges back into the inlet gas stream. Hydrocarbon/water condensate from the various separators located in the facility will be gathered by a common condensate header system. The header system will route the condensate to the gas/condensate heat exchanger. The heat exchanger's function is to pass heat from the gas discharged from compression into the condensate in order to stabilize the condensate. Stabilized condensate is then passed into a pipeline where it is transported to the Aka Gilcrest Gas Plant for storage and trucking. In the event of a pipeline interruption the stabilized condensate can be stored in on site atmospheric tanks. Vapors generated in the gas/condensate heat exchanger will be routed to a VRU compressor which discharges back into the inlet gas stream. Vapors from the tanks are less than 6 ton/yr of VOCs and will be routed to atmosphere. COLORADO Air Pollution Control Division Department of Public Health b Environment Form APCD-302 APCD Internal Use Only Received Date Approved? ❑ Approval Date Operating and Maintenance Plan Template for Glycol Dehydration Systems Ver. June 22, 2020 The Air Pollution Control Division developed this Operating and Maintenance Plan (OaM Plan) for glycol dehydration systems that use emissions controls, permitted at synthetic minor and major oil and gas facilities in the State of Colorado. One oam Plan may be used for multiple dehydration systems at one facility if each are controlled and monitored in the same manner. An OFtM Plan shall be submitted with the permit application when required. The facility operator must comply with the requirements of the OI}M Plan upon commencement of operation. An existing approved oam Plan may be modified without a permit modification or permit reissuance, but the operator must adhere to the requirements of the existing approved oam Plan until an approval letter is issued for the new OftM Plan. The operator is required to use the division -developed atm Plan template forms in order to meet minimum expectations within a standard, organized format. Do not modify the structure and/or content of this template. If the facility or emission unit is subject to other state or federal regulations with duplicative requirements, the operator must follow the most stringent regulatory requirement. Please note that O&M requirements are different for facilities in the Denver Metro and North Front Range 8 -hour ozone nonattainment area. For sources that are subject to the Title V Operating Permits program: In accordance with Colorado Regulation No. 3, Part C, Section V.C.5., some or all of the monitoring specified in this O&M plan will be incorporated as specific conditions in the source's Title V Operating Permit (if applicable). Additional monitoring not listed in this O&M Plan may be included in the source's Operating Permit in order to satisfy the periodic monitoring requirements of Regulation No. 3, Part C, Section V.C.5.b. Submittal Date: August 7, 2020 Section 1 - Source Identification For new permits, some of this information (i.e., Facility AIRS ID, Permit Number, and AIRS Point ID) may not be known at the time of application.

Page 3 of 5 CDPHE COLORADO Air Pollution Control Division Department of Public Health b Environment b Condenser Maximum Outlet Temperature If the emissions unit is controlled with a secondary control device and no control efficiency is being claimed for the condenser, then the condenser outlet temperature does not need to be monitored and there is no maximum condenser outlet temperature. If a control efficiency is claimed for the condenser, the maximum condenser outlet temperature shall be: Table 2: Condenser Maximum Outlet Temperature ❑ 160 °F ❑ °F A maximum temperature greater than 160 °F requires approval from the division. Supporting documentation must be submitted with the permit application and made available to the division upon request. Elevated Open Flare An open flare permitted after May 1, 2014 and used to comply with Regulation No. 7 Section XVII must be approved by the division as an alternate emission control device prior to operation, in accordance with Regulation No. 7 Section XVI1.6.2.e.; see PS Memo 15-03. d Pilot Light Monitoring Options If emissions are controlled by combustion device, then the operator must indicate in Table 3 the method by which the presence of a pilot light will be monitored. One primary method for Pilot Light Monitoring must be checked and, optionally, secondary methods may be checked. Table 3: Pilot Light Monitoring Primary Secondary Monitoring Method ❑ /2 Visual Inspection ❑ ❑ Optical Sensor L ❑ Auto -Igniter Signal �1 Thermocouple e Visible Emissions Observation and Method 22 Options At the frequency specified in Table 1, the operator is required to conduct an inspection of the subject combustion device for the presence or absence of smoke (e.g., visible emissions). If smoke is observed during the visible emissions inspection, the operator has the option to either (1) immediately shut-in the emissions unit to investigate the cause of the smoke, conduct any necessary repairs, and maintain records of the specific repairs completed; or (2) conduct a formal Method 22 observation to determine whether visible emissions (as defined per Regulation No. 7, Section XVII.A.17.) are present. If a Method 22 is conducted, the record of the observations shall be maintained as required in Section 3 of this OaM Plan. If visible emissions are observed by Method 22, the operator shall immediately conduct any necessary repairs and maintain records of the specific repairs completed; if repair cannot be immediately completed, the operator shall shut-in the emissions unit, conduct any necessary repairs, and maintain records of the specific repairs completed. The division has historically approved a "check box" to satisfy the Method 22 documentation procedures. The division will continue to accept the "check box" recordkeeping format in instances where no visible emissions are observed in order to demonstrate compliance.with the Method 22 requirement. If a flare is not subject to Regulation No. 7 requirements (as described in the permit), a similar approach may be employed where the operator may conduct an inspection for presence or absence of smoke, and, if smoke is observed, the operator has the option to (1) immediately conduct repairs and maintain records of the specific repairs completed; (2) shut-in the emissions unit to investigate the cause of the smoke, conduct any necessary repairs, and maintain records of the specific repairs completed; or (3) conduct a formal Method 9 observation to determine the opacity of the visible emissions, and conduct repairs if necessary. Page 4 of 5 CDPHE COLORADO Air Pollution Control Division Department of Public Health b Environment f Thermal Oxidizer: Minimum Combustion Chamber Temperature If emissions are controlled by thermal oxidizer, the minimum combustion chamber temperature shall be: Table 4: Thermal Oxidizer Minimum Combustion Chamber Temperature U 1400 °F Equal to the average combustion chamber temperature observed during the most recent division - approved stack testing. g Vapor Recovery Unit (VRU) or Recycled or Closed Loop System In the space provided below, please provide a description of the emission control system, including an explanation of parameters monitored, monitoring frequency, and how the system design ensures that emissions are being routed to the appropriate system at all times, or during all permitted runtime. Also, provide a description of how downtime is tracked and recorded. Attach additional pages if necessary. Vapors from the flash tank are recovered using the VRU. Operators will verify that the VRU is functioning properly on a daily basis. Downtime is tracked and recorded in an operating log when the VRU is down. h Routed to Reboiler Burner as Fuel In the space provided below, please provide a description of the emission control system, including an explanation of how the system design ensures that emissions are being held or rerouted when the reboiler is not firing. Describe the cycling frequency of the burner. Describe the other parameters and frequency for monitoring of this emissions control approach. Attach additional pages if necessary. Section 5 - Additional Notes and oam Activities Please use this section to describe any additional notes or operation and maintenance activities, or if additional space is needed from a previous section. Attach additional pages if necessary. No control efficiency is claimed for the condenser. Flash tank emissions are sent to the facility inlet using a closed loop system when VRU is down. Condenser vent emissions are sent to VRU when combustion device is down.
