Best Available Control Technology (BACT ) Guideline 3.2.1
Last Update: 1/9/1995


Diesel I.C. Engine - > 449 hp, used for testing of crankcase emission controls
Pollutant Achieved in Practice or in the SIP Technologically Feasible Alternate Basic Equipment
NOxNOx emissions of 7.2 grams/hp-hr or less OR Turbocharger with intercooler or aftercooler and timing retarded 4 relative to standard timing
PM10Low-sulfur diesel fuel (0.05% by weight sulfur or less) and positive crankcase ventilation or crankcase control device


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.
