The Division will use the information provided on the APEN to determine whether the land development project requires an air permit. If an air permit is required, the APEN will become part of the permit application package. In accordance with Colorado air regulations, the Division has up to 90 days to issue a permit once a complete APEN is received. If an incomplete APEN is received, the Division may request additional information. The 90-day permit-processing clock will start once the additional information is received. If a permit is required for your land development project, site operations cannot commence until the air permit has been issued. You must plan ahead! Obtaining an Air Permit Land development projects that that are greater or equal to 25 contiguous acres and/or 6 months in duration typically require an air permit. The land development permitting process has been streamlined to generate a final "temporary" land development air permit in one step. The temporary air permit is applicable through the project's "Commence" and "Stop" dates listed on the APEN. The temporary permit expires at the requested "Stop" date. As a rule of thumb, land development activities may be considered complete when all disturbed areas are stabilized from dust emissions. If an extension or modification to the air permit is required, contact the Division to discuss the change and determine whether a new APEN is required. Temporary land development permits are typically issued for a period of up to five years. Based on the information provided on the APEN, the permit may cover a single land development activity or a series of activities (or project phases) over a defined period of time. ➢ Types of Air Permits Currently the Air Pollution Control Division offers two types of permits for land development projects.
