of the CAA.

DATES: The proposed rule published on May 8, 2009 (74 FR 21594),

4, 2007 comprehensive SIP revision request for the Baltimore Area, is 
withdrawn as of December 4, 2015.

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.
