Using HYSYS & the reverse separator methodology, they modelled the gas which the LP Separator liquid was in equilibrium with (LP Separator Gas), saturated the LP Gas with the modelled gas and then ran that through the anticipated model design to determine the composition of the LP Gas. Because the LP Liquid was saturated, this is anticipated to be a more conservative estimation than just using the modelled equilibrium gas. This methodology is not typically used, as a sample upstream is normally available for the modeling. Additionally, the sample pressure was not labelled with the units, so we are unable to verify that the sample occured along the phase envelope.

No This sample should represent tie 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 modif ed (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 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. Are facility -wide permitted ern ssions of VOC greater than or equal to 90 tons per year? No If yes, the permit wil 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 and initial compliance test condition to demonstrate the destruction efficiency of the combustion device based on inlet and outlet ccncentration sampling You have indicated above that the monitored process parameter is natural gas vented.

They are slightly different from the calculations/methodologyused by the source as they directly used the lb/hr rate. Because of this slight difference, the values reflected in the permit will be those requested by the source. This source is using the "Reverse Separator" methodology. The modelling software is able to determine the composition of thegas which is in equilibrium with the LP Separator Liquids.

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-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/cdthe/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.
