Title V of the Clean Air Act requires ‘major sources’ of air pollutants and certain other sources to obtain and operate in compliance with a Title V Operating Permit.
- A major source with respect to Title V is a source above that emits above the major source thresholds:
- Emits over 100 tons per year of any criteria pollutant;
- Emits over 10 tons per year of a single HAP; or
- Emits over 25 tons per year of any combination of HAPs.
These facilities are subject to and the associated operating permits are issued pursuant to the Administrative Rules of Montana Title 17, Chapter 8, Subchapter 12 (ARM 17.8.12).
Once you have a Title V Permit
The goal of a TV Operating Permit is to serve as a single document that contains all the applicable requirements associated with the source. The Operating Permit contains permit limits, monitoring, recordkeeping and reporting requirements that are designed to make sure the source knows when it is or isn’t in compliance with air quality regulations.
Operating permits require annual certifications that the source is complying with all applicable requirements. Additionally, permits must be renewed every 5 years.
