Section 07 - Initial and Periodic Sampling and Testing Requirements
You have indicated above the monitored process parameter is Liquid Througpot The following question does not require an answer.
Using Liquid Throughput to Monitor Compliance
Does the company use site specific emission factors based on a pressurized liquid sample (Sampled upstream of the`I'�'y',
equipment covered under this AIRS ID) and process simulation to estimate emissions? Yap..;
This sample 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 Compliance" testing requirement to collect a site -specific liquid sample 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.
Does the company request a control device efficiency greater than 95% for a flare or combustion device?

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]
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 froms/liq'
separators, well head casing, pneumatic pumps, blowdown events, among other events. If your emulsion 'does""
not fall into this category, there may be a more specific APEN for your source. In addition, the General`AI3EN
(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.gov/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.
