• %vw – stack gas moisture content, wet volume percent 

• dscfm – stack gas flow rate, dry standard (one atm., 68°F) cubic feet per minute 

• ug/dscm – micrograms per dry standard (one atm., 68°F) cubic meter 

• lb/hr – pollutant mass emission rate, pounds per hour 

• gr/dscf – grains per dry standard (one atm., 68°F) cubic feet 

• F 1⁄2 PM – front half particulate. This includes the acetone rinse of the M29 probe 

and filter.
