Best Available Control Technology (BACT ) Guideline 3.2.2|
Last Update: 11/8/2002
Limited Use (1,000 hr/yr max) Diesel-Fired IC Engine - Located at a Stationary Source, non-emergency, non-Transportable, and not used to drive an electrical generator
|Pollutant||Achieved in Practice or in the SIP||Technologically Feasible||Alternate Basic Equipment|
|CO||Oxidation Catalyst||Electric motor|
|NOx||6.9 grams/bhp-hr||1.0 grams/bhp-hr (Selective Catalytic Reduction, or equal)||1. Electric motor 2. Natural gas or LPG fired IC engine or turbine|
|PM10||A 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.||1. Electric motor 2. Natural gas or LPG fired IC engine or turbine|
|SOx||Low-sulfur fuel (< 500 ppm sulfur, by weight). or Very low-sulfur fuel (< 15 ppm sulfur by weight), where available.||1. Electric motor 2. Natural gas fired IC engine or turbine|
|VOC||Catalytic filter; thermal oxidizer, or equal||Electric motor|
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 requirement.
2. The District will waive the 0.1 grams PM10/bhp-hr requirement (see Note 1) for engines which meet all three of the following:
a. were permitted within the District on March 5, 2001 for operation as emergency power generators,
b. are equipped with a particulate exhaust filter, and
c. are proposed to be operated as limited-use, electrical power generators at the original stationary source.
Engines which are transferred to another stationary source.
3. Revised 11/8/02 pursuant to CARB guidelines for Distributed Generation Equipment.|
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.
