Last Update: 8/2/1996


Diesel Fired IC Engine - < 700 hp, Serving a Deep Water Channel Dredging Operation, and Not Used to Drive an Electrical Generator
Pollutant Achieved in Practice or in the SIP Technologically Feasible Alternate Basic Equipment
NOx1. Selective Catalytic Reduction utilizing ammonia injection 2. NOx emissions of 7.2 grams per horsepower-hour or less OR Turbocharger with intercooler or aftercooler and timing retarded 4 degrees relative to standard timing.
PM10Low sulfur diesel fuel (0.05% by weight) and positive crankcase ventilation (PCV) or crankcase control device that is 90% efficient
SOxLow sulfur diesel fuel (0.05% by weight)
VOC1. Catalytic Oxidizer and positive crankcase ventilation (PCV) or crankcase control device that is 90% efficient 2. Positive crankcase ventilation (PCV) or crankcase control device that is 90% efficient


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.
