Air Pollution Control Division
Notice of a Proposed Project or Activity Warranting Public
Comment
Website Title: Extraction Oil Et Gas, Inc. - Westwind Production Facility - Weld County
Notice Period Begins: September 28, 2017
Notice is hereby given that an application for a proposed project or activity has been submitted to the
Colorado Air Pollution Control Division for the following source of air pollution:
Applicant: Extraction Oil Et Gas, Inc.
Facility: Westwind Production Facility
Exploration Et Production Well Pad.
SWSW Section 7 T6N R67W
Weld County
The proposed project or activity is as follows: Construction permits for flaring of separator gas and VRT gas
when sales line is not available. Other equipment permitted in this project are condensate storage tanks
(GP08), truck loadout (GP07), three (3) engines (GP02), and produced water storage tanks (permit -exempt).
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):
• the source is requesting a federally enforceable limit on the potential to emit in order to avoid other
requirements
• 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 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 Permits 17WE0528 and
17WE0529 have been filed with the Weld County Clerk's office. A copy of the draft permits and the
Division's analyses 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. Any such comment must be submitted in writing to the following addressee:

Below is a table summarizing the emission factors and resulting emissions calculated by the operator and used in the permit. As described in the
additional notes section below, the difference is likely due to rounding. This difference is small enough to be considered insignificant and thus
acceptable for permitting purposes.

Regulatory Applicability
AQCC Regulation 1
This source is subject to the opacity requirements for flares in Section II.A.5:'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.'
AQCC Regulation 2
Section I.A applies to all emission sources. "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 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."
AQCC Regulation 7
Was the well newly constructed, hydraulically fractured, or recompleted on or after August 1, 2014?
Yes
This separator is subject to Reg 7, Section XVII.G. and control requirements of Reg 7, Section XVII.B.2
Additional Notes:
The emission factors calculated in this preliminary analysis are not identical to the emission factors reported by the operator on the APEN. However, the difference
between the values is small enough as to be considered insignificant. The difference between these values is most likely due to rounding in the calculations. The
'.. emission factors reported by the operator in the application will be used for permitting purposes.
The applicant submitted an erroneous Promax model with the original application (didn't properly enter the analytical data). I received a revised talc sheet and APEN
on 8/25/17 which corrected this. The entries above reflect that revised Promax run.

Notes
My calculated amounts above are slightly different from those reported by applicant. I will accept applicant's amounts.
Mole %, are from a ProMax run based on a site -specific pressurized liquid analysis collected 3/24/17.
Emissions are based on 3066 hours of venting from this point per year. Flow meter will measure actual amount.
I assumed a MW of 114.23 Ib/Ibmol for C8+.

Gas Analysis
Below is a table summarizing the emission factors and resulting emissions calculated by the operator and used in the permit. As described in the
additional notes section below, the difference is likely due to rounding. This difference is small enough to be considered insignificant and thus
acceptable for permitting purposes.

Regulatory Applicability
AQCC Regulation 1
This source is subject to the opacity requirements for flares in Section II.A.5:'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.'
AQCC Regulation 2
Section I.A applies to all emission sources. "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 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."
AQCC Regulation 7
Was the well newly constructed, hydraulically fractured, or recompleted on or after August 1, 2014?
Yes See additional notes section below for further discussion.
This separator is subject to Reg 7, Section XVII.G. and control requirements of Reg 7, Section XVII.B.2
Additional Notes:
The emission factors calculated in this preliminary analysis are not identical to the emission factors reported by the operator on the APEN. However, the difference
'.. between the values is small enough as to be considered insignificant. The difference between these values is most likely due to rounding in the calculations. As such,
the emission factors reported by the operator in the application will be used for permitting purposes.

Air Pollutant Emission Notice (APEN) and "<.'-.cEIVED \'
Application for Construction Permit SEP 1 2 2017 I
Alt sections of this APEN and application must be completed for both new and existing facilities, including APEN_:
updates. An application with missing information may be determined incomplete and may be returned or result in
longer application processing times. You maybe charged an additional APEN fee if the APEN is filled out
incorrectly or is missing information and requires re -submittal.
This APEN is to be used for Natural Gas Venting only. Natural 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. 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 at:
www.colorado.gov/cdphe/apcd.
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). See Regulation No. 3, Part A, II.C. for revised APEN requirements.

All sections of this APEN and application must be completed for both new and existing facilities, including APEN
updates. An application with missing information may be determined incomplete and may be returned or result in
longer application processing times. You may be charged an additional APEN fee if the APEN is filled out
incorrectly or is missing information and requires re -submittal.
This APEN it to be used for Natural Gas Venting only. Natural 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. 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 at:
www.colorado.gov/cdphe/apcd.
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). See Regulation No. 3, Part A, II.C. for revised APEN requirements.
