Additional decreases in ROG <br />(VOC) can be obtained by using High Velocity Low Pressure Applicators (HVLP), and <br />NO VOC coatings, which contain <lg/1 VOC. The majority of architectural coatings will <br />be applied as interior paints which would offer the best reduction using Low VOC and No <br />VOC paints. Using Low and No VOC coatings along with HVLP equipment it is estimated <br />would likely reduce the VOC emissions below the calculated mitigated values generated in <br />the URBEMIS model for the proposed projects. <br />Table 5 -4 Architectural Coatings <br />Pollutant <br />Unmitigated <br />(lbslday) <br />Mitigated <br />(lbslday) <br />SCAQMD <br />Threshold <br />ROG <br />66.67 <br />66.67 <br />75 <br />NOx <br />0.04 <br />0.04 <br />100 <br />CO <br />0.71 <br />0.71 <br />550 <br />PM 10 <br />0.01 <br />0.01 <br />150 <br />SOz <br />0.00 <br />0.00 <br />150 <br />PM 2.5 <br />0.00 <br />0.00 <br />55 <br />CO2 <br />96.71 <br />96.71 <br />NIA <br />Bold - underline indicates exceedance of SCAQMD Threshold. <br />02/02/11 15 <br />
