Note: The controlled emissions factors for this point are based on a control efficiency of 100% when
emissions are routed to the VRU and a control efficiency of 95% when emissions are routed to the
enclosed combustors) during VRU downtime. The site specific emission factors for this source
were developed using a site specific pressurized liquid sample in conjunction with ProMax. The
pressurized liquid samplewas obtained from the outlet of the HLP separator for the Ottenhoff
29R 323 well, on 07/08/2019. The sample temperature and pressure are 116°F and 19.2 psig
respectively. Uncontrolled actual VOC and HAP emissions are calculated by multiplying the
emission factors in the table above by the total condensate throughput. Controlled actual VOC
and HAP emissions are calculated by multiplying uncontrolled emissions by a 100% control
efficiency when emissions are routed to the VRU and a 95% control efficiency when emissions are
routed to the enclosed combustor(s) during VRU downtime. The TNRCC Flare Emission Guidance
(Technical Supplement 4) N0x and CO emission factors (0.138 lb/MMBtu and 0.2755 lb/MMBtu
respectively) in the table above were converted to units of lb/bbl using a gas molecular weight
of 45.5493 lb/lbmole, a standard molar volume of 379.41 scf/lb-mole, a VOC mole % of 67.14%
and a heat content of 2,557.47 Btu/scf. Actual NOx and CO emissions are calculated by
multiplying the emission factors in the table above by the total condensate throughput during
VRU downtime.

Note:
The NOx and CO emission factors listed in the table above were obtained by multiplying the AP -42
Chapter 13.5 NOx and CO emission factors (0.068 lb/MMBtu and 0.31 lb/MMBtu respectively) by
a heat value of 1,136 Btu/scf. The VOC emission factor in the table above was obtained by
multiplying the AP -42 Chapter 1.4 emission factor by a ratio of 1,136 Btu/scf to 1,020 Btu/scf.
Actual emissions are calculated by multiplying the emission factors in the table above by the
total fuel flow of the pilot gas. Pilot light fuel flow is based on a constant rate of 15.6 scf/hr.
There are a total of eleven combustors used to control emissions from the condensate storage
vessels. As a result, the total pilot gas fuel flow is 171.6 scf/hr.
Total actual emissions are obtained from the sum of emissions resulting from the storage vessels
and combustion of waste gas from the storage vessels (process 01) and the combustion of pilot light
gas (process 02).
6) In accordance with C.R.S. 25-7-114.1, each Air Pollutant Emission Notice (APEN) associated with
this permit is valid for a term of five years from the date it was received by the Division. A revised
APEN shall be submitted no later than 30 days before the five-year term expires. Please refer to
the most recent annual fee, invoice to determine the APEN expiration date for each emissions point
associated with this permit. For any questions regarding a specific expiration date call the Division
at (303)-692-3150.

Section 03 - Description of Project
PDCEnergy Inc. (PDC) submitted an application requesting permit coverage for several newsources ata new synthetic minor oil andgas well production facility located in the ozone non -
attainment area. With this application, the operator is requesting permit coverage', for condensate storage vessels, produced water storage vessels, hydrocarbon loadout;'and natural gas
fired reciprocating internal combustion engines (RICE). The RICE are obtaining permit coverage under the GP02, and the loadout is` obtaining coverage under the GP07. The produced water
storage vessels are addressed under permit #19WE0799. This preliminary analysis only addresses the twenty (20) 538 barrel condensate storage vessels. - !.
This source is AP EN required because uncontrolled actual VOC emissions are greater than 1 tpy (CO AQCC Regulation 3, Part A, Section II.B.3.a ).: Additionally, ;the source is permit requires(
because the uncontroled VOC emissions from all APEN required sources at the facility are greater than 2 tpy (CO AQCC Regulation 3 Part B, Section II.D2.a.);.
Public comment is required for this source because new synthetic minor limits are being established in order avoid: other requirements and the change in VOC emissions as a -:result oft
project are greater than 25 tpy.

Section 07- Initial and Periodic Sampling and Testing Requirements
Does the company use site specific emissions factento estimate emissions?
If yes and If there are flash emissions, are the emissions factors based on a pressurized liquid water sample drawn
at the facility being permitted and analyzed using flash liberation analysis? This sample should be considered
representative which generally means she-spedflc and collected within one year of the application received date.
However, if the facility has not been modified (e.g., no new wells brought on-line), then it may be appropriate to
use n alder site -specific sample.
If no, the permit will contain an "Initial Compliance" testing requirement to develop a site spedflc emissions factor. See PS Memo
t0,s 5.9 and 5.12 for additional guidance On testing.
Does thecompany request a control device efficiency greater than 95% for a flare at combustion device? yt__=_t/N/A - emissions {TOT this source are not controlled.
If yes, the permit will contain and Initial compliance test condition to demonstrate the destruction efficiency of the combustion device based on inlet and outlet concentration sampling

Condensate Storage Tank(s) APEN
Form APCD-205
Air Pollutant Emission Notice (APEN) and
Application for Construction Permit
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 is to be used for tanks that store condensate associated with oil and gas industry operations. If your
emission source does not fall into this category, there may be a more specific APEN available for your source (e.g.
crude oil storage tanks, produced water storage tanks, hydrocarbon liquid loading, etc.). 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 and associated addendum forms can be found on the Air Pollution Control Division (APCD)
website at: www.colorado.gov/pacific/cdphe/air-permits.
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 is to be used for tanks that store produced water associated with oil and gas industry operations. If your
emission source does not fall into this category, there may be a more specific APEN available for your source (e.g.
crude oil storage tanks, condensate storage tanks, hydrocarbon liquid loading, etc.). 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 and associated addendum forms can be found on the Air Pollution Control Division (APCD)
website at: www.colorado.Rov/pacific/cdphe/air-permits.
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,
