With this application, the operator is requesting permit coverage for condensate storage vessels, produced water storage vessels, hydrocarbon loadout, VRT venting, separator venting and natural gas fired RICE. The RICE are obtaining permit coverage under the GPO2. This preliminary analysis only addresses the condensate storage vessels, The condensate storage vessels are APEN required because uncontrolled requested VOC emissions are greater than 1 tpy (Colorado AQCC Regulation 3, Part A, Section IL8.3.a.). Additionally, the source is permit required because uncontrolled VOC emissions from all APEN required sources at the facility are greater than 2 tpy (Colorado AQCC Regulation 3, Part 8, Section ILD..2.aPublic c.), NOs emo ment is ons as a result of the prired for oject are greater han 25 tpy, andis source because new etic minor limits tthe change in CO emissions ones as eing established result�of in order tothe project avoid othgreater t anre50 t menu.

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 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 develop a site specific emissions factor based on guidelines in PS Memo 05-01.

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 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.
