Figure 4.4-1 shows the sensitive receptors in the project vicinity. <br /> Regulatory Setting <br /> Clean Air Act <br /> The federal Clean Air Act(CAA) establishes EPA's responsibilities to protect and improve the <br /> nation`s air quality. EPA oversees the implementation of federal programs for setting air quality <br /> standards,permitting new and modified stationary sources,controlling toxic air contaminants,and <br /> reducing emissions from motor vehicles and other mobile sources.EPA also requires that each state <br /> prepare and submit a State Implementation Plan(SIP)that consists of background information, <br /> rules,technical documentation,and agreements that an individual state will use to attain <br /> compliance with the NAAQS within federally-imposed deadlines.State and local agencies implement <br /> the plans and rules associated with the SIP,but the rules are also federally enforceable. <br /> California Clean Air Act <br /> The California Clean Air Act(CCAA) establishes a statewide air pollution control program for <br /> California.ARB is the primary administrator of the CCAA.ARB's main responsibilities are to develop, <br /> adopt,implement,and enforce the state's motor vehicle pollution control program; administer and <br /> coordinate the state`s air pollution research program; adopt and update the CAAQS; review the <br /> operations of the local air pollution control districts; and review and coordinate the state's SIP for <br /> achieving NAAQS. <br /> Addendum No.2 to the Environmental Impact Report for 4 Z4 September 2012 <br /> the Redwood City Costco Wholesale Project ICF 00154.12 <br />
