Section 07-Initial and Periodic Sampling and Testing Requirements
,-Using Gas Throughput to Monitor Compliance
1
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 maybe 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.
eta
y r
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 affthis 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 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

t ; Gas Venting APEN - Form APCD-211
Air Pollutant Emission Notice (APEN) and
G°P"E Application for Construction Permit
Alt 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.
