Additional decreases in ROG <br />(VOC) can be obtained by using High Velocity Low Pressure Applicators (HVLP), and <br />NO VOC coatings, which contain <g/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 Unmitigated <br />(lbs/day) Mitigated <br />(lbs/day) SCAQMD <br />Threshold <br />ROG 66.67 66.67 75 <br />NOx 0.04 0.04 100 <br />CO 0.71 0.71 550 <br />PM 10 0.01 0.01 150 <br />S02 0.00 0.00 150 <br />PM 2.5 0.00 0.00 55 <br />C02 96.71 96.71 N/A <br />Isola-unuerune indicates exceedance of SCAQMD Threshold. <br />02/02/11 <br />15 <br />75B-123
