The 2007 Certified EIR assumed an annual throughput of 9 million gallons per year for a 16 fueling position GDF. Source: City <br /> of Redwood City,Final Environmental Impact Report for the Redwood City Costco Wholesale Project(SCH#2005092047), <br /> Section 3(Comment Documents and Responses), Master Responses to Air Quality Comments. Daily throughput is calculated <br /> assuming 365 days/year. <br /> 2. Assume that the gasoline throughput for the existing facility is the same as evaluated in the 2007 Certified EIR. <br /> 3. The maximum throughput for the proposed 20 fueling position GDF will not exceed 18 million gallons per year(double the <br /> throughput assumed in the 2007 Certified EIR). Daily maximum allowable throughput is calculated assuming 365 days per <br /> year. Note that the Bay Area Air Quality Management District(BAAQMD)Permit No. G#11933 for the Costco Wholesale <br /> Redwood City gasoline dispensing facility limits gasoline throughput to 29.8 million gallons per year. <br /> 4.
