Best Available Control Technology (BACT ) Guideline 3.2.5
Last Update: 3/5/2001


Diesel I.C. Engine - Used for starting a Gas Turbine
Pollutant Achieved in Practice or in the SIP Technologically Feasible Alternate Basic Equipment
NOxCertified NOx emissions of 6.9 g/bhp-hr or less
PM10A Performance Standard of - = or < 0.02 grams/bhp-hr and - very low-sulfur fuel (15 ppmw sulfur) where available. or a Minimum Technology Standard - 0.1 grams PM10/bhp-hr, and - a catalytic particulate filter (or equal), and - very low-sulfur fuel (15 ppmw sulfur) where available.
SOxLow-sulfur fuel (< 500 ppm sulfur, by weight). or Very low-sulfur fuel (< 15 ppm sulfur by weight), where available.
VOCPositive Crankcase Ventilation (PCV) or Crankcase Control Device that is at least 90% efficient
Any engine model included in the ARB or EPA diesel engine certification lists and identified as having a PM10 emission rate of 0.149 grams/bhp-hr or less, based on ISO 8178 test procedure, shall be deemed to meet the 0.1 grams/bhp-hr requirement.

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.
