PUBLIC NOTICE OF A PROPOSED PROJECT
OR ACTIVITY WARRANTING PUBLIC COMMENT
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: Wildhorse 06-06I4H
Oil and Gas Exploration and Production Site
NWNW Sec 6 T9N R59W
Weld County
The proposed project or activity is as follows: The applicant proposal to construct an exploration and production
facility that will include Crude Oil Storage, Produced Water Storage, Loadout of Hydrocarbon Liquids, and
Separator Venting
The Division has determined that this permitting action is subject to public comment per Colorado Regulation No.

• 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 14WE0459 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

approved methods.
ADDITIONAL REQUIREMENTS
15. A revised Air Pollutant Emission Notice (APEN) shall be filed: (Reference: Regulation
No. 3, Part A, II.C)
a. Annually by April 30th whenever a significant increase in emissions occurs as
follows:
For any criteria pollutant:
For sources emitting less than 100 tons per year, a change in actual emissions
of five (5)tons per year or more, above the level reported on the last APEN; or
For sources emitting 100 tons per year or more, a change in actual emissions
of five percent or 50 tons per year or more, whichever is less, above the level
reported on the last APEN submitted; or
For any non-criteria reportable pollutant:
If the emissions increase by 50% or five (5) tons per year, whichever is less,
above the level reported on the last APEN submitted to the Division.

e. No later than 30 days before the existing APEN expires.
16. 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 though construction had not yet commenced on the source. The source shall
not exceed the Federal program threshold until a permit is granted. (Regulation No. 3
Part D).
GENERAL TERMS AND CONDITIONS
17. 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

18. If this permit e artn fin- t=u tuzatio ." 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.
19. 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.
20. Unless specifically stated otherwise, the general and specific conditions contained in this

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 of a source may request a hearing
before the AQCC for review of the Division's action.
22. 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.
23. 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
