original comments (CSD comment). kk) Install STOP control signage and striping at all driveway exits. 6) SAN JOAQUIN VALLEY AIR POLLUTION CONTROL DISTRICT (Contact: (2091 557-6400)Sta# Contact: Charly Vann (559)T_230 5934 a) Based on information provided to the District, Project specific annual emissions of criteria pollutants are not expected to exceed any of the following District significance thresholds: 100 tons per year of carbon monoxide(CO), 10 tons per year of oxides of nitrogen (NOx), 10 tons per year of reactive organic gases (ROG), 27 tons per year of oxides of sulfur (SOx), 15 tons per year of particulate matter of 10 microns or less in size (PM10), or 15 tons per year of particulate matter of 2.5 microns or less in size (PM2.5). Therefore, the District concludes that the Project would have a less than significant impact on air quality when compared to the above-listed annual criteria pollutant emissions significance thresholds. b) The IS/MND indicates that the Project would include several onsite restaurants,the nature of which are not known at this time. The IS/MND presented a qualitative assessment which relies upon the District to require controls on any future sources that may emit toxic air contaminants, making the impact less than significant. Currently, the only source of restaurant emissions subject to District regulations is chain-driven charbroilers. Therefore, it would be reasonable to conclude that chain- driven charbroilers would have a less than significant health impact. However, please note that sources such as underfired charbroilers, deep fat fryer, or griddles are not subject to District rules and their emissions may have a significant health impact. c) District Rule 9510 (Indirect Source Review) is intended to mitigate a project's impact on air quality through project design elements or by payment of applicable off-site fees. The proposed Project is subject to District Rule 9510 (Indirect Source Review) if it has or will receive a project-level discretionary approval from a public agency and will equal or exceed 2,000 square feet of commercial space, or(2) if it has or will receive project-level approval from a public agency and will equal or exceed 10,000 square feet of commercial space. If subject to the rule, an Air Impact Assessment (AIA) application is required prior to applying for project-level approval from a public agency. In this case, if not already done, please immediately submit an AIA application to the District to comply with District Rule 9510ln the case the Project is subject to District Rule 9510 an AIA application is required and the District recommends that demonstration of compliance with District Rule 9510, before issuance of the first building permit, be made a condition of Project approval. Information about how to comply with District Rule 9510 can be found online at: http://www.valleyair.org/ISR/ISRHome.htm. The AIA application form can be found online at: http://www.valleyair.org/ISR/ISRFormsAndApplications.htm. d) The gas station portion of this Project will be subject to District Rule 2010 (Permits Required) and Rule 2201 (New and Modified Stationary Source Review) and will require District permits. Prior to construction, the Project proponent should submit to the District an application for an Authority to Construct (ATC). For further information or assistance, the Project proponent may contact the District's Small Business Assistance (SBA) Office at(209) 557-6446. e) Particulate Matter 2.5 microns or less in size (PM2.5)from under-fired charbroilers pose immediate health risk. Since the cooking of meat can release carcinogenic PM2.5 species like polycyclic aromatic hydrocarbons, controlling emissions from under-fired charbroilers will have a substantial positive impact on public health. Charbroiling emissions occur in populated areas, near schools and residential neighborhoods, resulting in high exposure levels for sensitive Valley residents. The air quality impacts on neighborhoods near restaurants with under-fired charbroilers can be significant on days when meteorological conditions are stable, when dispersion is limited and emissions are trapped near 11
