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: Whiting Oil and Gas Corporation
Facility: Razor 33-2813H
Crude Oil Exploration and Production Facility
SWSW SEC33 TION R58W
Weld County
The proposed project or activity is as follows: The applicant proposes to add three(3)crude oil storage tanks, one
(1) produced water storage tank, a truck loadout, and one separator (associated gas flaring) to the Razor 33-2813H
facility
The Division has determined that this permitting action is subject to public comment per Colorado Regulation No.
3, Part B, Section 1II.C due to the following reason(s):
• permitted emissions exceed public notice threshold values in Regulation No. 3, Part B. Section IlI.C.La
(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 13WE2697 E2697 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 www.colorado.gov/cdphe/AirPublicNotices
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:

e. No later than 30 days before the existing APEN expires.
19. Federal regulatory program requirements (i.e. PSD, NANSR or Title V Operating Permit)
shall apply to this source at any such time that this source becomes major solely by virtue of
a relaxation in any permit condition. Any relaxation that increases the potential to emit
above the applicable Federal program threshold will require a full review of the source as

GENERAL TERMS AND CONDITIONS
20. 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.
21. 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.
22. This permit is issued in reliance upon the accuracy and completeness of information
supplied by the applicant 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 applicant or applicant's agents. It is valid only for the
equipment and operations or activity specifically identified on the permit.
23. 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.
24. 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 applicant, or the Division revokes a permit, the applicant
or owner or operator of a source may request a hearing before the AQCC for review of the
Division's action.
25. 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.
26. Violation of the terms of a permit or of the provisions of the Colorado Air Pollution Prevention
and Control Act or the regulations of the AQCC may result in administrative, civil or criminal
enforcement actions under Sections 25-7-115 (enforcement), -121 (injunctions), -122 (civil
penalties), -122.1 (criminal penalties), C.R.S.

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 3
An APEN is required for this source because uncontrolled VOC emissions
Part A. exceed two tons per year in an attainment area.
A permit is required for this source because uncontrolled VOC emissions from
this facility exceed five tons per year in an attainment area.
Part B: This source is not subject to Section III.D.2(Minor Source RACT)because it
is not located in a nonattainment area.
Is public comment Public Comment Required
