5,000 cubic yards of materials per day are required to submit a Fugitive Dust Control Plan or a Large Operation Notification Form to SCAQMD. Based on the size of the Project area (approximately 1.4 acres) a Fugitive Dust Control Plan or Large Operation Notification would not be required. SCAQMD's Rule 403 minimum requirements require that the application of the best available dust control measures is used for all grading operations and include the application of water or other soil stabilizers in sufficient quantity to prevent the generation of visible dust plumes. Compliance with Rule 403 would require the use of water trucks during all phases where earth moving operations would occur. Compliance with Rule 403 has been included in the CalEEMod modeling for the proposed project. Per SCAQMD Rule 1113 as amended on June 3, 2011, the architectural coatings that would be applied after January 1, 2014 will be limited to an average of 50 grams per liter or less of VOCs for building coatings and 100 grams per liter or less of VOCs for traffic coatings. The phases of the construction activities which have been analyzed below for each phase are: (1) demolition, (2) grading, (3) building construction, (4) paving, and (5) application of architectural coatings. Details pertaining to the project's construction timing and the type of equipment modeled for each construction phase are available in the CalEEMod output in Appendix B. Construction -Related Regional Impacts The construction -related criteria pollutant emissions for each phase are shown below in Table 6. Table 6 shows that none of the project's emissions will exceed regional thresholds. Therefore, a less than significant regional air quality impact would occur from construction of the proposed project. Construction -Related Local Impacts Construction -related air emissions may have the potential to exceed the State and Federal air quality standards in the project vicinity, even though these pollutant emissions may not be significant enough to create a regional impact to the South Coast Air Basin. The proposed project has been analyzed for the potential local air quality impacts created from: construction -related fugitive dust and diesel emissions; from toxic air contaminants; and from construction -related odor impacts. Local Air Quality Impacts from Construction The SCAQMD has published a "Fact Sheet for Applying CalEEMod to Localized Significance Thresholds" (South Coast Air Quality Management District 2011b). CalEEMod calculates construction emissions based on the number of equipment hours and the maximum daily disturbance activity possible for each piece of equipment. In order to compare CalEEMod reported emissions against the localized significance threshold lookup tables, the CEQA document should contain the following parameters: (1) The off -road equipment list (including type of equipment, horsepower, and hours of operation) assumed for the day of construction activity with maximum emissions. (2) The maximum number of acres disturbed on the peak day. (3) Any emission control devices added onto off -road equipment. (4) Specific dust suppression techniques used on the day of construction activity with maximum emissions. The CalEEMod output in Appendix B show the equipment used for this analysis. As shown in Table 7, the maximum number of acres disturbed in a day would be 2 acres during demolition and grading. The local air quality emissions from construction were analyzed using the SCAQMD's Mass Rate Localized Significant Threshold Look -up Tables and the methodology described in Localized Significance Threshold Methodology prepared by SCAQMD (revised July 2008). The Look -up Tables were developed by Cabrillo at First Mixed Use Residential g3ldJ101 Air Quality, Global Climate Change, HRA, and Energy Impact Analysis 29 19386
