Emergency Diesel I.C. Engine Driving a Fire Pump
|Pollutant||Achieved in Practice or in the SIP||Technologically Feasible||Alternate Basic Equipment|
|NOx||Certified NOx emissions of 6.9 g/bhp-hr or less|
|PM10||0.1 grams/bhp-hr (if TBACT is triggered) (corrected 7/16/01) 0.4 grams/bhp-hr (if TBACT is not triggered)|
|SOx||Low-sulfur diesel fuel (500 ppmw sulfur or less) or Very Low-sulfur diesel fuel (15 ppmw sulfur or less), where available.|
|VOC||Positive crankcase ventilation [unless it voids the Underwriters Laboratories (UL) certification]||Catalytic Oxidation|
1. 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
2. A site-specific Health Risk Analysis is used to determine if TBACT is triggered. (Clarification added 05/07/01)|
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.
