Air Pollutant Emission Notice (APEN)and
CDPHE Application for Construction Permit
All sections of this APEN and application must be completed for both new and existing facilities, including APEN
updates. incomplete APENs will be rejected and will require re-submittal. Your APEN will be rejected if it is filled
out incorrectly, is missing information,or lacks payment for the filing fee. The re-submittal will require payment
for a new filing fee.
This APEN is to be used for gas venting only.Gas venting includes emissions from gas/liquid separators,well head
casing, pneumatic pumps, blowdown events,among other events. If your emission unit does not fall into this
category, there may be a more specific APEN for your source(e.g.amine sweetening unit, hydrocarbon liquid
loading,condensate storage tanks,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 can be found on the
Air Pollution Control Division(APCD)website.
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.

and upon such occurrence, this permit must 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.
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.
25. 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.

Section 03 - Description of Project
Applicant is requesting a permit for a new emissions point. Applicant is proposing to send commingled vapors from the vapor recovery tower (VRT) and LP separators to
combustors. Previously, these vapors were sent to a vapor recovery unit (VRU) and compressed to the sales gas pipeline. Applicant is metering the streams (LP & VRT)
together using a single gas flow meter. This request is being accomodated since applicant is using the VRT gas composition (higher VOC percentage and molecular weight) to
estimate the composition from the commingled stream .

Section 07 - Initial and Periodic Sampling and Testing Requirements
Using Gas Throughput to Monitor Compliance
Does the company use site specific emission factors based on a gas sample to estimate emissions? Yes
This sample should represent the gas outlet of the equipment covered under this AIRs ID, and should have been 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 an older site-specific sample.
If no, the permit will contain an "Initial Testing Requirement" to collect a site-specific gas sample from the equipment being permitted and conduct an emission factor
analysis to demonstrate that the emission factors are less than or equal to the emissions factors established with this application.
Are facility-wide permitted emissions of VOC greater than or equal to 90 tons per year? No
If yes, the permit will contain:
-An "Initial Testing Requirement" to collect a site-specific gas sample from the equipment being permitted and conduct an emission factor analysis to demonstrate that the
emission factors are less than or equal to the emissions factors established with this application.
-A "Periodic Testing Requirement" to collect a site-specific gas sample from the equipment being permitted and conduct an emission factor analysis to demonstrate that the
emission factors are less than or equal to the emissions factors established with this application on an annual basis.
Will the operator have a meter installed and operational upon startup of this point? No
If no, the permit will contain a condition that requires the operator to calculate gas throughput using the liquid throughput until the meter is installed and operational (not
to exceed 180 days). This condition will use the "Volume of waste gas emitted per BBL of liquids throughput" (scf/bbl) value in section 03.
Does the company request a control device efficiency greater than 95% for a flare or combustion device? No
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

Separator Venting Emissions Inventory
Section 08 - Technical Analysis Notes
-Applicant has elected to, conservatively, show emissions for both the LP separator and VRT using the gas profile for the VRT applied to the volume expected from both units plus a 20% buffer.
-NOx and CO limits are inclusive of emissions from combustion of combustor pilot. Pilot emissions are based on 0.5 Mscf/day gas fbw and heat content of 1000 btu/scf. This equates to 182.5 MMBtu/yr for each combustor. For a total of
two (2) combustors controlling emissions from this sauce, pilot emissions are 0.012 tpy NOx and 0.057 tpy CO using AP -42 Chapter 13 emission factors. These totals are added to the limit in the tables above.
-Although facility emissions are approaching major source thresholds, I will not require periodic sampling of the LP/VRT stream since applicant is conservatively assuming the commingled LP separator and VRT gas stream is represented by
the VRT gas composition for emission calculation purposes. The LP gas is significantly lower in VOC and as such, I do not bel ive periodic sampling will increase accuracy of emission factors.
