Abstract
In this action, the EPA is promulgating a redesignation request and State Implementation Plan (SIP) revision submitted by the state of Missouri on June 13, 1997. Additional material was sent on June 15, 1998. The request is to redesignate the portion of the St. Louis metropolitan area, currently a carbon monoxide (CO) nonattainment area, to a CO attainment area. Under the Clean Air Act (CAA) as amended in 1990, a redesignation to attainment may be promulgated if the state demonstrates full compliance with the redesignation requirements set forth in section 107(d)(3)(E). In this action, the EPA is also approving Missouri's SIP revision regarding the state's CO maintenance plan.
