Abstract
The Environmental Protection Agency (EPA) is taking final action to approve elements of state implementation plan (SIP) submissions from Michigan and Wisconsin while taking final action to approve some elements and disapprove other elements of SIP submissions from Illinois and Minnesota regarding the infrastructure requirements of section 110 of the Clean Air Act (CAA) for the 2008 lead National Ambient Air Quality Standards (2008 Pb NAAQS). The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA. Illinois and Minnesota already administer federally promulgated regulations that address the final disapprovals described in today's rulemaking. Therefore, these two states are not obligated to submit new or additional regulations to EPA.
