Operating Permits and Licenses:

Either an operating permit or an air pollution license is required to operate air pollution creating equipment or devices. The types of operating permits and licenses are:

• Title V Operating Permit - Required for major facilities. Once issued, this permit lasts for 5 years. Select the application form or addendum 1, addendum 2, or addendum 3.  The instructions can be found in application instructions. 
• Synthetic Minor Operating Permit - May be used by a major facility that is willing to accept a federally enforceable permit limitation that restricts potential emissions to below major source thresholds.  Once issued, this permit lasts for 5 years.  Select the application or instructions.
• Natural Minor Operating Permit - Required for minor facilities. Once issued, this permit lasts for 5 years. Select the application and instructions.
• General Plan Approval and Operating Permit - For minor facilities whose only pollution sources are covered by a general plan approval and operating permit, this document will act as the operating permit as well as the plan approval. Once issued, this permit lasts for 5 years. Select Pre-Construction Permits for more information.
• Air Pollution License - Required for de minimis facilities. Licenses expire on October 31 of each year. Select the application form.
• Indefinite License - Required for boilers or furnaces with a rated capacity of less than 2 million BTU/hr or less, or less than 5 million BTU/hr and burning only No. 2 grade or lighter commercial fuel oil, or less than 10 million BTU/hr and burning only natural gas. Indefinite licenses are only issued once and do not need to be renewed. Select the application form.
• Operating Permit Exemption - Minor facilities may request exemption from operating permit requirements by accepting emission limitations below the de minimis levels. If the request is accepted, the facility will become a de minimis facility and be required to maintain an air pollution license instead of an operating permit. Select the Request for Exemption from City of Philadelphia Operating Permit Requirements.
