What is a Synthetic Minor Source?
Sources that have the potential to emit 100 ton/yr or greater of a criteria pollutant, 10 ton/yr or greater of any hazardous air pollutant, or 25 ton/yr or greater of any combination of hazardous air pollutants, and for which the permittee accepts a federally enforceable limit in the Permit to Operate that limits the potential to emit to the same criteria specified for a minor source.
What are federally enforceable limits?
Typically, a federally-enforceable limit is a physical or operational limitation on the capacity of a source to emit an air pollutant that is capable of being enforced by the federal government and citizens in federal court. A limitation has been considered federally enforceable if it is enforceable as a practical matter.
Examples of federally enforceable limits include:
- Throughput limits/production rate limits
- Operational limits
- Fuel type and/or usage amount limits
- Emission limits over a set period of time
How do I apply for a Synthetic Minor Source Permit to Operate?
Obtaining a minor source permit usually begins with the permittee applying for and receiving a Construction Permit.
Sources that received a construction permit under
Section 33-15-14-02 must notify the Department within 15 days of initial startup to satisfy the requirement to apply for a PTO.
A PTO is then issued after the conditions of the construction permit (PTC) have been verified by the Department with a facility inspection. For those sources that were not issued a construction permit (i.e., portable sources), an application for a PTO must be made on forms supplied by the Department prior to initiating operations.
Is a public comment period required?
Yes. Public participation concurrent with an EPA review period (30-day comment/review period) is required prior to issuing synthetic minor permits under the Minor Source Permit to Operate Program.
