Who Needs A Major Source Operating Permit?
A Major Source (Part 70) Operating Permit is required of companies that have operations involving a major air contaminant source. These companies include the following:
- Facilities with the potential to emit 10 tons per year of any hazardous air pollutant (HAP)
- 25 tons per year of any combination of HAPs
- 100 tons per year of any regulated air pollutant
- Facilities subject to acid rain requirements under Title IV of the Clean Air Act
- Facilities with lower tons per year limits in non-attainment areas
- Any other source the EPA Administrator determines by rulemaking should be included.
All industries that are potential sources of air pollution, unless specifically exempt as determined in the Air Pollution Ordinance, Section 4-56(c)(11) and (12), must receive an installation permit before constructing, installing, or reconstructing any equipment that has the potential to emit air pollutants. Installation permits contain emissions limitations and operating requirements that must be agreed to by the source prior to receiving the permit. A Certificate of Operation must be issued or a Part 70 permit application must be received prior to operating the equipment. In addition, all installation permits, with the exception of New Source Review (NSR) cases which may require more time, are required to undergo a 30 day public participation opportunity period.
