Facilities that have low overall air emissions and qualify as one of the conditionally exempt source categories may be exempt from needing a permit.
First, determine if your facility qualifies as an insignificant facility. Insignificant facilities are not required to notify the MPCA about their status.
If your facility cannot qualify as an insignificant facility, it may qualify as conditionally exempt if you operate in one of these sectors:
- auto-body refinishing
- coating
- woodworking
- concrete manufacturer
- gasoline service station
Eligibility criteria, notification forms, and other information specific to the facilities above is available on the MPCA’s conditionally exempt facilities webpage.
