**SUPPLEMENTARY INFORMATION :**  On May 8, 2009 (74 FR 21594), EPA published a proposed rule to disapprove the ozone attainment demonstration portion of a comprehensive State Implementation Plan (SIP) revision request submitted by the State of Maryland on June 4, 2007 to meet the Clean Air Act (CAA) requirements for attaining the 1997 8- hour ozone National Ambient Air Quality Standard (NAAQS) for the Baltimore moderate nonattainment area (Baltimore Area). On May 26, 2015 (80 FR 29970), EPA determined that the Baltimore Area attained the 1997 8-hour ozone NAAQS, thereby suspending the area’s obligations to submit an attainment demonstration and other planning requirements related to attainment of the 1997 8-hour ozone NAAQS for as long as the area continues to attain the standard. On October 20, 2015, the State of Maryland withdrew the attainment demonstration (including modeling and weight of evidence), 2009 attainment year inventory, contingency measures for attainment, and 2009 transportation conformity budgets contained in Maryland’s June 4, 2007 SIP revision request.
