The Construction Permits Section is responsible for the review and approval of all pre-construction air permitting in Iowa with the exception of Linn and Polk counties where local air programs are present.
New facilities must be designed to meet emissions standards and not result in a violation of ambient air quality standards. Facilities meeting state and federal requirements are issued construction permits which also include operating requirements to assure continued compliance.
More detailed analyses are required for large and complex projects. This includes those that involve Prevention of Significant Deterioration (PSD), Major Source Non-Attainment Area permitting, State Implementation Plan (SIP) maintenance areas, sources netting out of these requirements, major brand new (Greenfield) facilities, etc. This more detailed analysis recognizes the impact large sources of emissions can have on a region.
The Iowa DNR strongly encourages pre-application meetings in order to facilitate review and permitting of these large and complex projects. The DNR cannot assure how quickly that projects submitted without this prior coordination can be reviewed or permitted. Please review the guidance materials below for the type of project your facility will be proposing. If you are unsure what applies to you, or simply need help with the construction permitting process, call 1-877-AIR-IOWA (1-877-247-4692).
