As part of this project, the operator has also separately permitted 3 natural gas reciprocating internal combustion engines at the site through general permits. The Division has determined that this permitting action is subject to public comment per Colorado Regulation No. 3, Part B, Section III.C due to the following reason(s): • permitted emissions exceed public notice threshold values in Regulation No. 3, Part B, Section III.C.1.a (25 tpy in a non -attainment area and/or 50 tpy in an attainment area) • the source is requesting a federally enforceable limit on the potential to emit in order to avoid other requirements The Division has made a preliminary determination of approval of the application. A copy of the application, the Division's analysis, and a draft of Construction Permit 18WE0156 have been filed with the Weld County Clerk's office. A copy of the draft permit and the Division's analysis are available on the Division's website at https://www.colorado.gov/pacific/cdphe/air-permit-public-notices The Division hereby solicits submission of public comment from any interested person concerning the ability of the proposed project or activity to comply with the applicable standards and regulations of the Commission. The Division will receive and consider written public comments for thirty calendar days after the date of this Notice.

Flash Tank Control: CAS # Pollutant Uncontrolled Emission Factors lb/MMscf Waste Gas Combusted Source NOx 192.79 AP -42 CO 384.87 AP -42 Note: The combustion emission factors are based on a heating value of 1397 Btu/scf. Control of Purge Gas: CAS # Pollutant Uncontrolled Emission Factors lb/MMscf Waste Gas Combusted Source NOx 155.94 AP -42 CO 311.32 AP -42 Note: The combustion emission factors are based on a heating value of 1130 Btu/scf. Actual emissions are calculated by multiplying the emission factors in the table above by total design rate of all combustor pilot lights. 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. A revised APEN shall be submitted no later than 30 days before the five-year term expires. Please refer to the most recent annual fee invoice to determine the APEN expiration date for each emissions point associated with this permit. For any questions regarding a specific expiration date call the Division at (303)-692- 3150. 7) This permit fulfills the requirement to hold a valid permit reflecting the glycol dehydration unit and associated control device per the Colorado Oil and Gas Conservation Commission rule 805b(2)(B) when applicable.
