Potential-to-Emit Modules

An objective for Kentucky’s Division of Compliance Assistance (DCA) is to help regulated entities comply with environmental requirements. One way DCA assists individuals, regulated entities and government agencies is by answering inquiries regarding environmental regulations and providing materials to make the regulations easier to understand.

Kentucky’s ECAP has developed online learning modules to help facilities understand and conduct potential-to-emit (PTE) calculations. PTE calculations quantify the maximum amount of air contaminants that can be potentially emitted from the facility, given that operations occur 24 hours a day, seven days a week. PTE calculations are the core component of an air permit application serving as a communication tool between the applicant and the permit reviewer.

A facility-wide PTE summary aids in the assessment of applicable requirements and determining if the facility is capable of meeting those requirements. In the simplest of terms, PTE is a way for an entity to numerically illustrate the air quality emissions generated.

The new learning modules unravel the complexity of air emission assessments by introducing the key concepts for locating and understanding potential emissions. The modules will take you through step-by-step examples of assessing a facility, finding emission factors and conducting the calculations.

The Potential-to-Emit Introduction learning module begins by identifying what potential-to-emit means, what pollutants are assessed in air emission calculations, how to identify air contaminant sources at your facility and what information to gather about these emission sources in order to conduct PTE calculations. The introductory module also presents the different types of air permits and approvals for Kentucky and provides resources for identifying potentially applicable regulations and what content should be included in an air quality application.

Next, the Potential-to-Emit Components learning module takes you further into learning each variable of the PTE formula, what considerations should be made while conducting an emission point analysis and how to carry out the PTE calculations. To supplement the information provided in the two potential-to-emit modules, the Emission Factors: AP42 and EPA WebFIRE learning module was developed specifically to help entities navigate the most common emission factor sources.

These learning modules are now available along with others developed by DCA, which address a few of the common environmental regulations including, but not limited to, hazardous waste determination, fugitive dust regulations, air quality compliance reports, recordkeeping practices and household pharmaceutical waste management.

These modules can be found on our Resource Documents webpage and are just one way DCA assists individuals, regulated entities and government agencies.
