To apply for a new permit or modify an existing permit, follow these steps.
2. Emissions Calculation & Regulatory Analysis Workbook
The APCD has developed a form to assist you in completing your emissions calculations and regulatory analysis, and closely reflects internal forms used for the same purpose. The use of this form is optional, and this form does not necessarily include all types of equipment or all possible regulatory scenarios. This form is updated periodically.
3. Complete Attachments A through J for your application.
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 a new filing fee. See our Application Rejection Frequently Asked Questions page for more information.
"A. APEN Fees."]You must pay the APEN fee for every APEN submitted. General Permits
will require additional fees.
Include an APEN for each emissions point subject to APEN reporting requirements.
"E. Ambient air impact analysis." An ambient air impact analysis is required if emission increases requested in your application are above the modeling thresholds in the Colorado Modeling Guideline for Air Quality Permits
. An ambient air impact analysis is not required for sources that emit only VOCs and no other criteria pollutants.
Include all existing, portable, and newly-requested emission points at your facility. This form isn't needed if your facility has only one emission point.
"G. Process description, flow diagram, and plot plan of emissions unit and/or facility." Attachment G does not require a specific APCD form. You can represent this in a written or graphical format or both, as appropriate. This attachment is not needed if your facility has only one emissions point.
"H. Operating and maintenance (O&M) plan - APCD Form Series 300." The Operating & Maintenance Plan forms
page has additional guidance and links to all templates available for download. O&M plans are required for each source with emission controls at a synthetic minor or major stationary source. They are not required if a source is covered by a General Permit or if the source is at a true minor facility.
"I. Regulatory analysis."]You may opt for us to complete the regulatory analysis. Submitting a regulatory analysis along with the permit application may speed up the issuance of the permit.
