Authority to Construct EvaluationA/C XXXXXFebruary 13, 2012Page 5Section 301 - Best Available Control Technology The proposed potential to emit from thisemissions unit exceeds the BACT thresholds for the affected pollutants as specified inSection 301.1 and below. Therefore, BACT will be required for VOC, PM10 and PM2.5.Pollutantlb/dayVOC 0NOx 0SOx 0PM10 0PM2.5 0CO 550Lead 3.3The SMAQMD BACT determination for automotive coating operations, together with theBay Area AQMD, South Coast AQMD and the San Joaquin Valley Unified APCD BACTManuals were reviewed for automotive refinishing operations.The SMAQMD BACT determination for general coating using a paint spray booth in anautomotive coating operation was issued on 7-28-05 (BACT Determination No. 22). Theanalyses performed for control technologies using catalytic incineration, thermalincineration, and carbon adsorption in coating operations have shown that VOC emissionsof 4,700 lb or less per year from a single paint spray booth exceed the District’s $17,500per ton cost effectiveness level for maximum cost per ton of pollutant controlled. Since theproposed VOC emissions limitation will not exceed this cost effectiveness threshold, BACTas Achieved in Practice shall be required. BACT requirements for the coating operation atCNC Auto Body will be as follows:a) Low VOC coatings compliant with the current Rule 459 standards including thestandards that will become effective February 25, 2012; andb) High transfer efficiency application equipment.XXX Auto Body is proposing the following compliant coatings and solvents as summarizedbelow:Coating Category(Rule 459)Primer/PrimerSealerBACT StandardsRule 459lb/galVOC Contentless water andexempt compoundslb/gal2.1 1.67ProposedCoating MaterialsPCL 901PolyprimerClear Coating 2.1 2.1 Matrix AG 40LVColor Coating 3.5 3.5 Matrix RSB-LVSolvent CleaningGun CleanerWax/Grease Rem0.2100.21Safety-Kleen ClearChoiceDominion LVAPC Wax &Grease Remover
