Using Liquid Throughput to Monitor Compliance
Does the company use site specific emission factors based on a pressurizedliouid sample(Sampled upstream of the
equipment covered under this Alps ID)and process simulation to estimate emissions? §g"
This sample should have been collected within one year of the application received date.However,if thefecility has not been modified(e.g.,no new
wells brought on-line),then R may heappropriate 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?
lives,the permit will contain and init1l compliancenwt condition to demonstratethe destruction efficiency of the combustion device hosed on inlet

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 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-2OO)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.
