What is PTE?
K.A.R. 28-19-200 General provisions; definitions.
(yy) ‘‘Potential-to-emit’’ means the maximum capacity of a stationary source to emit a pollutant under its physical and operational design. Any physical or operational limitation on the capacity of the source to emit a pollutant, including air pollution control equipment and restrictions on hours of operation or on the type or amount of material combusted, stored, or processed, shall be treated as part of its design if the limitation or the effect it would have on emissions is federally enforceable. Secondary emissions shall not be considered in determining the potential-to-emit of a stationary source.

What is PTE?
• 24-hour operation, 365 days per year
• Operate at maximum capacity
• No pollution control devices or practices

Reasons for evaluating
•It’s required by your permit
•Determine if you need a permit
•Demonstrate your facility is below certain thresholds
•Determine if permit needs have changed
•Determine if adding new equipment will require a construction permit

Operating permit (Class I)
• Required if your PTE exceeds these thresholds:• 100 tons per year NOx, SOx, PM10, VOC, CO
• 10 tons per year of any single hazardous air pollutant (HAP)
• 25 tons per year of combined HAPs
• Also referred to as Title V permits (EPA version)

Operating permit (Class II)
• Actual emissions are below Class I thresholds but PTE is above—limit PTE and apply for Class II operating permit
• Class II permit requires minimal record keeping and is simpler (and cheaper) than maintaining a Class I permit
• Class II permit-by-rule (KAR 28-19-561 through 564)

Step 2: Calculate PTE
• Select method(s) to use
• Gather needed information to perform calculations
• Calculate PTE for each criteria pollutant and HAP generated at your facility
• Contact SBEAP or KDHE Permitting Section for assistance
![Page 29: PTE - SBEAPWhat is PTE? K.A.R. 28-19-200 General provisions; definitions. (yy) ‘‘Potential-to-emit’’ means the maximum capacity of a stationary source to emit a pollutant under](https://reader030.vdocument.in/reader030/viewer/2022040818/5e63ffeb9144b7270220c9df/html5/thumbnails/29.jpg)
Step 3: Compare PTE results with thresholds
• Refer to SBEAP fact sheet, Five Steps to Determine Whether Your Facility Needs an Air Permit, Step 3, for tables with thresholds
• Determine which permit to apply for• Are you an existing Class II that needs to be a Class I?
• Are you an existing Class I that could be a Class II?
• Have you added a piece of equipment?• Do you need a construction approval?
• Do you need a construction permit?

Step 4: Apply for the appropriate permit
• To be discussed in the next few sessions
![Page 31: PTE - SBEAPWhat is PTE? K.A.R. 28-19-200 General provisions; definitions. (yy) ‘‘Potential-to-emit’’ means the maximum capacity of a stationary source to emit a pollutant under](https://reader030.vdocument.in/reader030/viewer/2022040818/5e63ffeb9144b7270220c9df/html5/thumbnails/31.jpg)
Conclusion
• PTE is fundamental to determining your permitting requirements
• If PTEs are below regulatory thresholds and no permit is needed for any other reason—• File calculations should they be requested later by an inspector
• Continue to track emissions, especially if product usage or product type changes
