Best Available Control Technology (BACT ) Guideline 1.9.14
Last Update: 2/9/2007


Natural Gas Fired Dryer with High Turndown Ratio**
Pollutant Achieved in Practice or in the SIP Technologically Feasible Alternate Basic Equipment
NOx<= 8.9 ppmvd*** @ 19% O2 (0.1 lb/MMBtu) low NOx burner4.3 ppmvd @ 19% O2 (0.048 lb/MMBtu) low NOx burner, or equalElectric Dryer
**For the purpose of this determination, a "high turndown ratio" is one that exceeds the turndown ratio of an ultra-low NOx burner system operating at 2.2 ppmv NOx @ 19% O2 or 1.1 ppmv NOx @ 19% O2. ***BACT will be established on a case-by-case basis to assure the lowest achievable emission rate, taking into account unique facility characteristics

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.
