PM2.5 direct emissions definition

PM2.5 direct emissions means finely divided solid or liquid material, with an aerodynamic diameter less than or equal to a nominal two-and-a-half (2.5) micrometers emitted to the ambient air as measured by an applicable reference method, or an equivalent or alternative method, specified in 40 C.F.R.

PM2.5 direct emissions means finely divided solid or liquid material, with an aerodynamic diameter less than or equal to a nominal two-and-a-half (2.5) micrometers emitted to the ambient air as measured by an applicable reference method, or an equivalent or alternative method, specified in 40 C.F.R. Chapter 1. Emissions shall include gaseous emissions from a source or activity which condense to form particulate matter at ambient temperatures. It does not include emissions of other gaseous precursors which may subsequently contribute to formation of secondary PM2.5 particles through chemical reactions.

PM2.5 direct emissions means solid particles, with an aerodynamic diameter less than or equal to nominal 2.5 micrometers, emitted directly from an air emissions source or activity, or gaseous emissions or liquid droplets from an air emissions source or activity which condense to form particulate matter at ambient temperatures. Direct PM2.5 emissions include elemental carbon, directly emitted organic carbon, directly emitted sulfate, directly emitted nitrate, and other inorganic particles (including but not limited to crustal material, and metals).
