NSPS Subpart 0000a Storage tank is subject to NSPS OOOO0 Regulation 8,Part E,MACT Subpart HH Storage Tank is not subject to MACE HH (See regulatory applicability worksheet for detailed analysis) Section 07-Initial and Periodic Sampling and Testing Requirements For condensate or crude oil tanks,does the company use the state default emissions factors to estimate emissions? If yes,are the uncontrolled actual or requested emissions for a crude oil tank estimated to be greater than or equal to 20 tons VOC per year OR are the uncontrolled actual or requested emissions for a condensate storage tank estimated to be greater than or equal to 80 tpy? If yes,the permit will contain an"Initial Compliance"testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 14-03, Does the company use a site specific emissions factor to estimate emissions? If yes and if there are flash emissions,are the emissions factors based on a pressurized liquid sample drawn at the facility being y. permitted(for produced water tanks,a pressurize liquid sample must be analyzed using flash liberation analysis)?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 maybe 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 14-03. 1,4:n1t Does the company request a control device efficiency greater than 95%for a flare or combustion device?

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 tanks that store condensate associated with oil and gas industry operations. If your emission source does not fall into this category, there may be a more specific APEN available for your source(e.g. crude oil storage tanks, produced water storage tanks, hydrocarbon liquid loading, 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 and associated addendum forms can be found on the Air Pollution Control Division(APCD) website at: www.colorado.gov/pacific/cdphe/air-permits. 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.).
