Best Available Control Technology (BACT ) Guideline 3.2.11
Last Update: 8/11/2014


Transportable Compression - Ignited IC Engines (Non-Agricultural)*
Pollutant Achieved in Practice or in the SIP Technologically Feasible Alternate Basic Equipment
COThe proposed engine shall meet the latest available CARB certification standard for the particular horsepower range. (Example: a 200 bhp engine proposed in 2014 shall be Tier 4i certified and meet the emission standard of 2.6 g-CO/bhp-hr)LPG/Propane Fired Engine
NOxThe proposed engine shall meet the latest available CARB certification standard for the particular horsepower range. (Example: a 200 bhp engine proposed in 2014 shall be Tier 4i certified and meet the emission standard of 1.5 g-NOx/bhp-hr)LPG/Propane Fired Engine
PM10The proposed engine shall meet the latest available CARB certification standard for the particular horsepower range. (Example: a 200 bhp engine proposed in 2014 shall be Tier 4i certified and meet the emission standard of 0.01 g-PM10/bhp-hr)LPG/Propane Fired Engine
SOxVery Low Sulfur Fuel (0.0015% fuel S by weight)
VOCThe proposed engine shall meet the latest available CARB certification standard for the particular horsepower range. (Example: a 200 bhp engine proposed in 2014 shall be Tier 4i certified and meet the emission standard of 0.14 g-VOC/bhp-hr)LPG/Propane Fired Engine
*For the purposes of this BACT guideline, Transportable Compression -Ignited IC engines are IC engines that remain or will remain at a location (any single site at a building, structure, facility, or installation) for 12 months or less or a shorter period of time for an engine located at a seasonal source.

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.
