CPM Reporting Threshold

Annual Operating Report

Condensable Particulate Matter Reporting Threshold

For CPM that is emitted from an emissions unit but not subject to any numerical emission limiting standards, AOR pollutant annual emissions must be reported for CPM, for each SCC, if CPM was emitted from the emissions unit during the reporting year in an amount, by SCC, equal to or greater than 5.0 tons/year and if information is available to estimate emissions. If such information is not available, CPM should not be listed as a reportable pollutant on the form.

A calculator to estimate CPM emissions based on some available CPM emissions factor information from AP-42 is provided at the following link:

  Note: This is not necessarily a complete list of CPM factors that may be available.
