the OEHHA’s Health Risk Assessment Guidelines(http://www.oehha.ca.gov/air/hot_spots/index.html)b. T-BACT Determinations:If the applicant chooses to operate a system that exceeds the health risk limit of one in onemillion, Toxic-Best Available Control Technology (T-BACT) is required. AutomotiveRefinishing operations that fall into this category must reduce coating usage or proposecoating/solvent replacements that drop the booth and facility risk levels to acceptable limits.Otherwise, the booth shall maintain a 90% capture efficiency and 95% destruction/removalefficiency for emissions of toxic air contaminants. In addition, the health risk number may notexceed 10 in one million for this situation. For projects requesting greater than 10 in onemillion, call the SMAQMD for more information on what is required.The following exhaust controls may be used as T-BACT emission control devices:PollutantROCT-BACT for AutomotiveRefinishingCatalytic/Thermal IncineratorsCarbon Adsorption3. New Source Review -- BACTa. Applicability:Rule 202, Section 301, requires that any new or modified emissions unit which results in anincrease in potential quarterly emissions for any affected pollutant having the potential to emitat levels exceeding those specified below, must apply Best Available Control Technology(BACT) for that pollutant.PollutantVOCNOxSOxPM10PM2.5COLeadBACT Trigger Level0 lb/day0 lb/day0 lb/day0 lb/day0 lb/day550 lb/day3.3 lb/dayb. VOC BACT Determinations:Applicants must provide BACT for new or modified stationary sources where the unitemission increase for the system exceeds the VOC limit of 0 lbs/day as proposed. BACT forautomotive refinishing operations without add-on controls is currently considered to be low-VOC coatings, high-efficiency spray application, solvent clean-up and surface preparationthat is in compliance with Rule 459 coupled with a 4,700 lb/qtr and 4,700 lb/year VOCemissions limit. This is the limit at which add-on exhaust controls are not cost-effective, aspreviously determined by the District under BACT determination number 22. For larger paintspray booths with exhaust flow rates of 30,000 acfm or more, use of the previously statedlimit to avoid add-on controls does not apply and an individualized BACT determination shallbe performed.The District may require a different more stringent technology/standard as BACT pursuant toRule 202, Section 204.1b.VI-9
4. New Source Review -- Emission OffsetsApplicants must provide emissions offsets for new or modified stationary sources where thecumulative emission increase for the facility exceeds the following levels (Rule 202, §302):PollutantPounds/QuarterVolatile Organic Compounds (VOC) 5,000Nitrogen Oxides (NOx) 5,000Sulfur Oxides (SOx) 13,650PM10 7,300PM2.515 TPYCarbon Monoxide (CO) 49,5005. New Source Review - California Environmental Quality Act (CEQA)The SMAQMD has developed a comprehensive permitting CEQA Guidance document. Projectreviews conducted in accordance with the policy manuals contained therein (including thismanual) have been determined to meet the CEQA criteria of ministerial and do not requireadditional CEQA review.In the event a project falls outside the scope of this policy manual (for example a new BACTdetermination or other situation already described within the CEQA guidance document), theproject shall follow the steps for CEQA review as detailed in the guidance document."6. Rule 217 – Public Notice Requirements for PermitsPrior to approving and Authority to Construct application for a new or modified stationary sourceor emissions unit which has an increase in potential to emit exceeding any of the following limitsor where emission offsets are required pursuant to Rule 202, the District must submit apreliminary decision to CARB and EPA for review and publish the preliminary decision solicitingpublic review and comment at least 30 days prior to final action on the application.PollutantPounds/QuarterVolatile Organic Compounds (VOC) 5,000Nitrogen Oxides (NOx) 5,000Sulfur Oxides (SOx) 9,200PM10 7,300PM2.510 TPYCarbon Monoxide (CO) 49,500VI-10
