New Iowa Air Permitting Option - Collection of Air Permits (CAP)

The Iowa DNR is proposing to create a new air quality construction permit option called a Collection of Air Permits (CAP). Current construction permit practice is to issue one permit per emission point. The new CAP permit option will still assign a permit number to each emission point but will consolidate requirements in one permit document.


Several changes have been proposed to the CAP based on comments received during the first CAP comment period in January 2016. Additionally, the CAP was modified to be consistent with the recently updated standard permit format.

MPCA Low-Emitting Facility (LEF) General Permit and Enforcement Amnesty

The Part 70 Low-Emitting Facility (LEF) General Permit is primarily intended for businesses with high potential emissions and low actual emissions that began operating without an air permit. Although any business meeting eligibility requirement can apply, businesses that are likely to apply include autobody shops, metal fabrication facilities, cabinet shops, other businesses that coat or paint, and facilities that have engines, boilers or tanks on site. Targeted facilities may have constructed a major source under the New Source Review (NSR) program and/or constructed and operated a major source of hazardous air pollutants.
