Last Update: 10/1/2002
Gas Turbine - < 50 MW, Uniform Load, Without Heat Recovery
|Pollutant||Achieved in Practice or in the SIP||Technologically Feasible||Alternate Basic Equipment|
|CO||6.0 ppmvd** @ 15% O2, based on a three-hour average (Oxidation catalyst, or equal).||90% control efficiency (SCONOx system, or equal).|
|NOx||5.0 ppmvd** @ 15% O2, based on a three-hour average (high temp SCR, or equal).||1. 2.5 ppmv @ 15% O2 (SCONOx system, or equal). 2. 3.0 ppmv (Dry Low-NOx combustors and SCR, or equal)|
|PM10||Air inlet cooler/filter, lube oil vent coalescer (or equal) and either PUC-regulated natural gas, LPG, or non-PUC-regulated gas with < 0.75 grams S/100 dscf.|
|SOx||PUC-regulated natural gas, LPG, or Non-PUC-regulated gas with < 0.75 grams S/100 dscf, or equal.|
|VOC||2.0 ppmvd** @ 15% O2, based on a three-hour average (Oxidation catalyst, or equal).||1. 90% control efficiency (SCONOx system, or equal).|
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.
