Approval and Promulgation of Implementation Plans; Designation of Areas for Air Quality Planning Purposes; Redesignation of the Baltimore Carbon Monoxide Area to Attainment and Approval of the Area's Maintenance Plan and Emission Inventory; State of Maryland
EPA is approving a maintenance plan and a request to redesignate the Baltimore carbon monoxide (CO) nonattainment area, which is located within the Baltimore City Central Business District (CBD) within the Baltimore Metropolitan Statistical Area. The maintenance plan and redesignation requests were submitted by the State of Maryland on September 20, 1995. Under the 1990 amendments of the Clean Air Act (CAA) designations can be revised if sufficient data is available to warrant such revisions. In this action, EPA is approving Maryland's request because it meets the maintenance plan and redesignation requirements set forth in the CAA. This action is being taken under section 110 of the CAA.
