Each University campus holds an Air Emission Permit issued by MPCA. The purpose of the permit is to identify all federal and state air quality rules that apply to the affected campus. The permit also contains air pollution limits for each significant emission source, defines allowable hourly and annual throughputs, and consolidates monitoring, recordkeeping and reporting requirements.
Each of the four major campuses holds an existing air emission permit, as follows:
- Twin Cities - Title V Federal Operating Permit (Major Source)
- Duluth - State Operating Permit
- Crookston - State Operating Permit
- Morris - State "Option D" Registration Permit
Standard reporting and recordkeeping requirements apply to all permits. Specific permit for each campus may have additional monitoring and reporting requirements.
Procedure for amending permit depends on the type of permit held. Federal permits are the most restrictive. State registration permits are the most flexible for purposes of making changes at the existing facility. Installation/modification of new equipment and processes may require permit amendment.
