  This "nonroad study" quantifies the contribution of nonroad sources to air pollution, including volatile organic compounds (VOCs), oxides of nitrogen (NOx), carbon monoxide (CO), and particulate matter (PM). The study covers 10 equipment categories, including: lawn and garden equipment, farm and construction equipment, recreational vehicles, marine vessels, and airport service equipment.
  Paper copies of this study are available from the National Technical Information Service (NTIS) - Publication #PB-92-126960.
