Released To: The Greeley Tribune
On: October 6, 2014
Published: October 9, 2014
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: Encana Oil & Gas (USA) Inc.
Facility: Gurtler Horizontal, State Peterson 1 20 Et 12 20 and Davis 1A 1B 1C Horizontal
Oil and gas production and exploration facilities
NWNW Section 30 T2N, R64W, NWNW Section 20, T5N, R63W, and SWNE Section 9,
T2N, R66W
Weld County
The proposed project or activity is as follows: Oil and gas exploration and production facilities with
condensate tanks.
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 Permits 14WE1013, 14WE1014
and 14WE1015 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. Any such comment must be submitted in writing to the following addressee:

1992)) in all subsections of Section II. A and B of this regulation.
R ulation 2-Odor
Section I.A- 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
002 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.
Re ulation 3-APENs Construction Permits Operating Permits PSD
Part A-APEN Requirements
Criteria Pollutants: For criteria pollutants, Air Pollutant Emission Notices are required for:
002 each individual emission point in a non-attainment area with uncontrolled actual emissions
of one ton per year or more of any individual criteria pollutant(pollutants are not summed)
for which the area is non-attainment.
(Applicant is required to file an APEN since emissions exceed 1 ton per year VOC)
Part B—Construction Permit Exemptions
002 Applicant is required to obtain a permit since uncontrolled VOC emissions from this
facility are greater than the 2.0 TPY threshold(Reg.3, Part B, Section ILD.2.a)
Regulation 6- New Source Performance Standards
NSPS Kb: for storage vessels greater than 19,800 gallons after 7/23/84.
Is this source greater than 19,800 gallons(471 bbl)? No
002 Is this source subject to NSPS Kb? No
WHY?There are 8-350 bbl tanks onsite(each less than 471 bbl), therefore,these tanks do
not meet the criteria of this subpart.

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.
26. Section 25-7-114.7(2)(a), C.R.S. requires that all sources required to file an Air Pollution

Section I.A- 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
001 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.
Regulation 3-APENs, Construction Permits, Operating Permits. PSD
Part A-APEN Requirements
Criteria Pollutants: For criteria pollutants,Air Pollutant Emission Notices are required for:
001 each individual emission point in a non-attainment area with uncontrolled actual emissions
of one ton per year or more of any individual criteria pollutant(pollutants are not summed)
for which the area is non-attainment.
(Applicant is required to file an APEN since emissions exceed 1 ton per year VOC)
Part B—Construction Permit Exemptions
001 Applicant is required to obtain a permit since uncontrolled VOC emissions from this
facility are greater than the 2.0 TPY threshold(Reg.3, Part B, Section II.D.2.a)
R-•ulation 6- New Source Performance Standards
NSPS Kb: for storage vessels greater than 19,800 gallons after 7/23/84.
Is this source greater than 19,800 gallons(471 bbl)? No
001 Is this source subject to NSPS Kb? No
WHY?There are 20-400 bbl tanks onsite(each less than 471 bbl),therefore,these tanks
do not meet the criteria of this subpart.

Section II.A.1 -Except as provided in paragraphs 2 through 6 below, no owner or operator
of a source shall allow or cause the emission into the atmosphere of any air pollutant which
001 is in excess of 20% opacity. This standard is based on 24 consecutive opacity readings
taken at 15-second intervals for six minutes. The approved reference test method for
visible emissions measurement is EPA Method 9 (40 CFR, Part 60,Appendix A(July,
1992)) in all subsections of Section II. A and B of this regulation.

Section I.A- 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
001 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.

Part A-APEN Requirements
Criteria Pollutants: For criteria pollutants,Air Pollutant Emission Notices are required for:
001 each individual emission point in a non-attainment area with uncontrolled actual emissions
of one ton per year or more of any individual criteria pollutant(pollutants are not summed)
for which the area is non-attainment.
(Applicant is required to file an APEN since emissions exceed 1 ton per year VOC)
Part B—Construction Permit Exemptions
001 Applicant is required to obtain a permit since uncontrolled VOC emissions from this
facility are greater than the 2.0 TPY threshold(Reg.3, Part B, Section ILD.2.a)
Regulation 6-New Source Performance Standards
NSPS Kb: for storage vessels greater than 19,800 gallons after 7/23/84.
Is this source greater than 19,800 gallons(471 bbl)? No
001 Is this source subject to NSPS Kb? No
WHY?There are 12-400 bbl tanks onsite(each less than 471 bbl), therefore, these tanks
do not meet the criteria of this subpart.

XII.VOLATILE ORGANIC COMPOUND EMISSIONS FROM OIL AND GAS OPERATIONS
(Applicant Is subject to the emission control regWrements for condensate tanks
001 since It is located in a non-attainment area.)
XVII.C STATEWIDE CONTROLS FOR OIL AND GAS OPERATIONS...
(Applicant Is currerttfy subject to this since actual uncontrolled emissions are
@reater than 20 tp OfbnC.)
_N t
MACT EEEE:Organ ids Distribution
001 This source is not subject to MACT EEEE because it is not located at a major source of
HAP.
001 MACT HH
This source is not subject to MACT HH because it is not located at a major source of HAP.

Section 14-Miscellaneous Application Notes
AIRS Point 001 Condensate Storage Tanks
A permit will be issued because the uncontrolled VOC emissions are greater than 2 TPY(permit
threshold).
Operator used the same emission factors used with the first APEN of this source as a GP01. Since then,
the emissions have increased greater than the GP01 permit limit;therefore,they require a CP_
I converted the emission factors to lb/1000 gal:
VOC= 11.074 lb/bbl* 1000/42=263.6667 lb/1000 gal
Benzene=0.041 lb/bbl*1000/42=0.9792 lb/1000 gal
n-hexane= 0.283 lb/bbl*1000/42=6.7381 lb/1000 gal
