Title V Operating Permits

In November of 1990, Congress completed a major re-drafting of the Federal Clean Air Act. Many of these changes dealt with stationary sources of air pollution. One of the most significant of those changes was the creation of the Operating Permit program in Title V of the Clean Air Act.


Operating permits include a listing of all air pollution regulatory requirements that apply to the source. The program does not allow for the addition of new emissions control requirements, but rather clarifies the air pollution control obligations of major sources by compiling in one document all of a source's compliance requirements. The intent is that by including all applicable requirements in one permit it will be easier for the source owner, the regulatory agency, and the public to determine if the source is in compliance. The permits contain monitoring, record keeping and reporting requirements designed to ensure that the source knows when it is and is not in compliance. Owners of sources with operating permits must certify that the source is in compliance each year, and the permits must be renewed every five years. Each operating permit that is issued is subject to Public Comment and offers the public an opportunity for a hearing before the Colorado Air Quality Control Commission.


Additionally, sources are provided certain flexibility options which allow them to make changes in the way they operate without needing a new or revised permit. This allows them to be able to more quickly take advantage of changing market conditions.


Who Needs Operating Permits?


Any source that emits or has the potential to emit more than 100 tons of any regulated air pollutant per year will be required to have an operating permit. In addition, any source that emits or has the potential to emit more than 10 tons per year of a hazardous air pollutant, or more than 25 tons per year of a combination of hazardous air pollutants, will be required to have an operating permit. This includes older sources which never before were required to obtain an air pollution permit.


New major sources must obtain a construction permit from the Division prior to construction and then must apply for an operating permit within 12 months of commencing operation. All source owners submitting applications for permits will be billed by the Division for the time spent processing the application. The legislature has set the processing fee at $76.45 per hour.

Operating Permit Forms


Each of the following files contain the Title V Operating Permit forms. Both a Word and a PDF file are provided.



As of January 1, 2014, the Colorado Air Pollution Control Division no longer accepts blank APENs. Additional fees will apply if an APEN is submitted without the necessary information. An application with missing information may result in longer processing times.  Please note that all APEN submissions should be completed using forms currently supplied by the Division (see Reg. 3, Part A, Section II.A).  If you need assistance, please refer to:




Operating Permits Issued


Each of the following permits have two files associated with it. The first file is a copy of the current operating permit. If a permit is modified, only the most current version of the permit will appear here.

The second file is a copy of the Technical Review document. This document is created by the permit review engineer to provide an overview of the facility and a general discussion of any important technical, regulatory or compliance issues that were encountered during the processing of the operating permit. If a permit is modified and an additional Technical Review document is generated, it will be added to the files associated with the facility. Any previous Technical Review documents will be maintained as well.
