GENERAL TERMS AND CONDITIONS:
19. This permit and any attachments must be retained and made available for inspection
upon request. The permit may be reissued to a new owner by the APCD as provided
in AQCC Regulation No. 3, Part B, Section II.B upon a request for transfer of
ownership and the submittal of a revised APEN and the required fee.
20. If this permit specifically states that final authorization has been granted, then the
remainder of this condition is not applicable. Otherwise, the issuance of this
construction permit does not provide "final" authority for this activity or operation of this
source. Final authorization of the permit must be secured from the APCD in writing in
accordance with the provisions of 25-7-114.5(12)(a) C.R.S. and AQCC Regulation No.
3, Part B, Section III.G. Final authorization cannot be granted until the operation or
activity commences and has been verified by the APCD as conforming in all respects
with the conditions of the permit. Once self -certification of all points has been
reviewed and approved by the Division, it will provide written documentation of such
final authorization. Details for obtaining final authorization to operate are located
in the Requirements to Self -Certify for Final Authorization section of this permit.
21. This permit is issued in reliance upon the accuracy and completeness of information
supplied by the owner or operator and is conditioned upon conduct of the activity, or
construction, installation and operation of the source, in accordance with this
information and with representations made by the owner or operator or owner or
operator's agents. It is valid only for the equipment and operations or activity
specifically identified on the permit.
22. Unless specifically stated otherwise, the general and specific conditions contained in
this permit have been determined by the APCD to be necessary to assure compliance
with the provisions of Section 25-7-114.5(7)(a), C.R.S.
23. Each and every condition of this permit is a material part hereof and is not severable.
Any challenge to or appeal of a condition hereof shall constitute a rejection of the
entire permit and upon such occurrence, this permit shall be deemed denied ab initio.
This permit may be revoked at any time prior to self -certification and final authorization
by the Air Pollution Control Division (APCD) on grounds set forth in the Colorado Air
Quality Control Act and regulations of the Air Quality Control Commission (AQCC),
including failure to meet any express term or condition of the permit. If the Division
denies a permit, conditions imposed upon a permit are contested by the owner or
operator, or the Division revokes a permit, the owner or operator or owner or operator
of a source may request a hearing before the AQCC for review of the Division's action.

24. 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.

The uncontrolled VOC emission factor was calculated using AP -42, Chapter 5.2, Equation 1
(version 1/95) using the following values:
S = 0.6 (Submerged loading: dedicated normal service)
P (true vapor pressure) = 9.7 psia
M (vapor molecular weight) = 46.28 Ib/Ib-mol
T (temperature of liquid loaded) = 524 °R
The uncontrolled non -criteria reportable air pollutant (NCRP) emission factors were calculated by
multiplying the mass fraction of each NCRP in the vapors by the VOC emission factor.

Notes
Mole %, MW, and mass fractions from Crow Valley sales gas analysis collected 11/18/2014.
Emissions are based on 8760 hours of operation per year.
The operator will be required submit an initial sample of the comingled gas stream that is routed to the open flare, to include both the separator gas and the
gas off of the heater treaters.

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?
no
This separator is not subject to Reg 7 Section XVII.G
