7.B. - Page 148 �/holesale Redwood City GDF Expansion Air Quality/Climate Change Analysis Page 3 Introduction Background In November 2006, the City of Redwood City released a draft Environmental Impact Report (EIR) for the Redwood City Costco Wholesale Project (City of Redwood City, 2006). The project comprised a 150,000 square foot warehouse retail building, a 16-position gasoline dispensing facility (GDF), 800 parking spaces, roadway improvements, and utility improvements. Following public review, the City responded to comments, revised the Draft EIR, and released the final EIR in May 2007 (City of Redwood City, 2007a). In June 2007, the Planning Commission certified the EIR (2007 Certified EIR). After an appeal of the project and issuance of an EIR Addendum containing corrected traffic analysis data (City of Redwood City, 2007b), the City Council upheld approval of the project for a 12-position GDF (rather than the 16-position facility evaluated in the 2007 Certified EIR). The 2007 Certified EIR analyzed the following impacts with respect to air quality: • Demolition/construction emissions (criteria pollutants2 associated with construction of the warehouse and GDF) • Operational emissions (criteria pollutants from motor vehicle traffic associated with the warehouse and GDF) • Carbon monoxide "hot spots" impacts associated with relocating the main site entrance from Charter Street to Willow Street • Gasoline dispensing facility toxic air contaminant impacts associated with benzene in gasoline • Gasoline dispensing facility center odors • Gasoline dispensing facility queuing impacts (short-term concentrations of carbon monoxide, nitrogen dioxide, and respirable particulate matter, or PM,o) With respect to the GDF, the air quality impact analysis assumed: • Dispensing of 9 million gallons of gasoline per year • Sixteen gasoline fueling positions • A net increase of 850 weekday trips from the gasoline dispensing facility The 2007 Certified EIR identified a potential for fugitive dust (PM,o) impacts to nearby sensitive receptors during project demolition/construction. With imposition of Condition 4.5-1 (basic and enhanced dust control measures), fugitive dust impacts were determined to be reduced to less Z"Criteria pollutants"are those pollutants(and pollutant precursors)for which the California Air Resources Board or U.S. Environmental Protection Agency have established health-and welfare-based standards. Typically, these include ozone [reactive organic gases(ROG)and nitrogen oxides (NOx)as ozone precursors], respirable particulate matter(PM�o), fine particulate matter(PM2.5), carbon monoxide (CO), and sulfur oxides(SOx). 7/30/2012
