**Potential To Emit Calculator for Hot Mix Asphalt Plants** 3/23/2015 This spreadsheet helps estimate a facility's potential to emit. It is provided for the convenience of the permitted community. EPA does not guarantee the accuracy or appropriateness of this information. Emission factor sources are subject to revision or correction. It is the permittee's responsibility to verify the accuracy of the information. EPA is not liable for errors or omissions.

This PTE calculator is only applicable to the asphalt plants subject to NSPS, Subpart I (i.e. all PM emission units are controlled) and only applicable to the asphalt plants with the dryers controlled by dry filters. The emission factors for the dryers controlled by scrubbers are not included in this spreadsheet since the use of scrubbers to control asphalt plants are rare. If you are NOT subject to NSPS, Subpart I, the PM/PM10/PM2.5 emission factors in this spreadsheet need to be revised to be based on the uncontrolled emission factors.

Note: Engines that are considered portable nonroad engines do not need to be included (see 40 CFR 1068.30)
