Description
Applicant pulled a pressurized liquid sample from HLP separator(117 psig,75F).In addition,applicant completed an extended gas analysis of sales gas emitted from HP side of HLP separator(113 psi,66f).These sample
results were recombined using ProMax at the well head conditions and modeled through the HLP separator,and storage tanks.The resulting scf/bbl(as reported above as scf of gas emitted from the buffer house per bbl of

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 out 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 40 tons per year in the ozone nonattainment
area OR are emissions greater than or equal to 90 tons per year in the ozone attainment area?
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?
If yes,the permit will contain initial and periodic compliance testing in accordance with PS Memo 20-02
Section 08-Technical Analysis Notes
See section 04 emission calculation description for more information on sampling and process simulation used to estimate emissions.
Applicant has indicated on the ADEN that source is not subject to Section XVII.G.(revised version citation is Regulation 7,Part D,II.F.Per this section,gas produced from wells that were constructed,hydraulically fractured or recompleted on or
after 8/1/14 are subject to control requirements.Based on the APENs submitted for storage tanks,no new wells have been added at this facility.
Applicant had originally requested to monitor emissions and process limits based on liquid throughput.However,it was communicated to the applicant that sources in NAA with uncontrolled emissions 0 50 tpy VOC would require meters.The..
operator agreed and will be given up to 180 days from issuance of permit to install and operate a meter.

�;�:��r Gas Venting APEN - Form APCD-211
4 Air Pollutant Emission Notice (APEN) and CCDPHE 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.
