Section 07 - Initial and Periodic Sampling and Testing Requirements
Does the company use the state default emissions factors to estimate emissions?
If yes, are the uncontrolled actual or requested emissions estimated to be greater than or equal to 80 tons VOC per year?
If yes, the permit will contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 05-01.
Does the company use a site specific emissions factor to estimate emissions?
If yes and if there are flash emissions, are the emissions factors based on a pressurized liquid sample drawn at the
facility being permitted? This sample should be considered representative which generally means site -specific and
collected within one year of the application received date. However, if the facility has not been modified (e.g., no
. wells brought on-line), then it may be appropriate to use an older site -specific sample.
.,...,�..... ........................__ ..........._,_
If no, the permit will contain ea "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 05-01.
Does the company request a control device efficiency greater than 95% for a flare or combustion device?
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 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?
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? gym' rsu;
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 she -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? Yes
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 B01_ 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?
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
You have indicated above that the monitored process parameter is natural gas vented. The following questions do
Section 08 -Technical Analysis Notes
*Confirmed with operator that this emission point represents emissions from the inlet high-pressure separators. Any gas that is flared from other wastegas sources should be evaluated separately.
*O&M plan submitted priorto publishing of new Division templates for flares and separators,Since the O&M plan does not contain a requirementforperiodicvisible emissions observations, I will include a requirement
'.. daily visibleemtssion chechsthat aloes with the requirement in O&M template for5eparatorf(ver. 1/1/18)
This flare is subject to Regulation 7 Section XVII L2 e and therefore requires approval as an alternative emission control device (AEC) The AEC wassubmitted by BBC on XX/XX/XXXX and approved This approval is based on criteria
contained in PS Memo 15-03 section 2.3 Spec f ca lly th s flare is not the primary destination for emissions, it meets a 95% Centro' efficiency with manufacturer guarantee of 98% for hydrocarbons and the flare will operate with no visiblei
emissions, be equipped With an auto -igniter, and otherwise comply with requirements of XVll $ aside from the requirement to be enclosed

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.Qov/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.

Natural Gas Venting APEN - Form APCD-211
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 Natural Gas Venting only. Natural 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. 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 at:
www.colorado.Rov/cdphe/apcd.
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.
