Estimating Emissions from Stationary Diesel Engines

To estimate emissions from stationary diesel engines at a facility, an owner/operator may use:

  •  Manufacturer data and specifications to verify their guaranteed level;
  •  USEPA or CARB certification levels for Tier 1-4 engines;
  •  Source test results, or
  • The default emission values presented below:

  Default SCAQMD Diesel Engine Emission Factors

 Pollutant  Emission Factor Units 
 PM  1.0  g/bhp-hr
 NOx  10 - 14.1  g/bhp-hr
 CO  5  g/bhp-hr
