Last Update: 6/1/2006


Ag Transportable Compression-Ignited IC Engine
Pollutant Achieved in Practice or in the SIP Technologically Feasible Alternate Basic Equipment
VOCThe proposed engine shall meet the latest available CARB certification standard for the particular horsepower range. (Example: a 200 bhp engine proposed in 2007 shall emit =< 0.149 g-PM10/bhp-hr if triggers BACT for PM10) LPG/Propane Fired Engine to meet 4702 (either lean, or rich w/3-way catalyst)
NOXThe proposed engine shall meet the latest available CARB certification standard for the particular horsepower range. (Example: a 200 bhp engine proposed in 2007 shall emit =< 0.149 g-PM10/bhp-hr if triggers BACT for PM10)LPG/Propane Fired Engine to meet 4702 (either lean, or rich w/3-way catalyst)

BACT is the most stringent control technique for the emissions unit and class of source. Control techniques that are not achieved in practice or contained in s a state implementation plan must be cost effective as well as feasible. Economic analysis to demonstrate cost effectiveness is requried for all determinations that are not achieved in practice or contained in an EPA approved State Implementation Plan.

This is a Summary Page for this Class of Source. For background information, see Permit Specific BACT Determinations on Details Page.
