An invoice for these fees will be issued after the permit is issued. The permit holder must pay the invoice within 30 days of receipt of the invoice. Failure to pay the invoice will result in revocation of this permit. (Regulation Number 3, Part A, Section VI.B.) 2) The production or raw material processing limits and emission limits contained in this permit are based on the consumption rates requested in the permit application. These limits may be revised upon request of the owner or operator providing there is no exceedance of any specific emission control regulation or any ambient air quality standard. A revised air pollution emission notice (APEN) and complete application form must be submitted with a request for a permit revision. 3) This source is subject to the Common Provisions Regulation Part II, Subpart E, Affirmative Defense Provision for Excess Emissions During Malfunctions. The owner or operator must notify the Division of any malfunction condition which causes a violation of any emission limit or limits stated in this permit as soon as possible, but no later than noon of the next working day, followed by written notice to the Division addressing all of the criteria set forth in Part II.E.1 of the Common Provisions Regulation. See: _. 4) The following emissions of non-criteria reportable air pollutants are estimated based upon the process limits as indicated in this permit. This information is listed to inform the operator of the Division's analysis of the specific compounds emitted if the source(s) operate at the permitted limitations.

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. 4.0 Are facility-wide permitted emissions of VOC greater than or equal to 40 tons per year in the ozone nonattainment �. area OR are emissions greater than or equal to 90 tons per year in the ozone attainment area? If yes,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. -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? 'fee 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 initial and periodic compliance testing in accordance with PS Memo 20-02 r1"'�/f ..:.� '� � ar � �i�✓G�,a(! �fJ�'f��rais,x�i' �yid �„;�.ri�f/rr �'ira/.," -�/r�//�ar��.rar ,;•.r,":� z P r ,iii," .� ✓ �Frc c /r ✓ H₹.cv pr 1 rl"w �/ .:;:r C: �'�q .a 'a� l� l - ' iri Yi 5 ow fi b r °l: lad ; f E.) `: �'�OH j °f, ,;: EN'i_ MMENIE Nei j U ., S O IN 111 ° ' j �� t a M E aggipsgng .r...:..?, ,.:.r. 1,19,. �, jil ti A's s.,_a "" w'.,._x .. ;W..3�...... . .: /:. €� .env .gym :s_✓.a" r.

Incomplete APENs will be rejected and wilt require re-submittal. Your APEN will be rejected if it is filled out incorrectly, is missing information, or lacks payment for the filing fee. The re-submittal will require payment for a new filing fee. This APEN is to be used for tanks that store crude oil associated with oil and gas industry operations. If your emission source does not fall into this category, there may be a specific APEN available for your source (e.g. condensate 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.). See Regulation No. 3, Part A, II.C. for revised APEN requirements.
