(1) EPA approves revisions to the Maryland State Implementation Plan for post 1996 rate of progress plans for milestone years 1999, 2002 and 2005 for the Cecil County portion of the Philadelphia-Wilmington-Trenton ozone nonattainment area. These revisions were submitted by the Secretary of the Maryland Department of the Environment on December 24, 1997, as revised on April 24 and August 18, 1998, December 21, 1999 and December 28, 2000.

(2) EPA approves the contingency plans for failure to meet rate of progress in the Cecil County portion of the Philadelphia-Wilmington-Trenton ozone nonattainment area for milestone years 1999, 2002 and 2005. These plans were submitted by the Secretary of the Maryland Department of the Environment on December 24, 1997, as revised on April 24 and August 18, 1998, December 21, 1999 and December 28, 2000.

(3) EPA approves revisions to the Maryland State Implementation Plan, submitted by the Secretary of the Maryland Department of the Environment on March 8, 2004, for the rate-of-progress (ROP) plan for year 2005 for the Cecil County portion of the Philadelphia-Wilmington-Trenton 1-hour ozone nonattainment area. These revisions update Cecil County's 2005 ROP plan's 1990 and 2005 motor vehicle emissions inventories and motor vehicle emissions budgets to reflect the use of the MOBILE6 emissions model, establish motor vehicle emissions budgets of 3.0 tons per day (tpd) of volatile organic compounds and 11.3 tpd of nitrogen oxides, and amend the contingency measures associated with the 2005 ROP plan for Cecil County.

(g) [Reserved]

(h) EPA approves the attainment demonstration for the Philadelphia area submitted as a revision to the State Implementation Plan by the Maryland Department of the Environment on April 29, 1998, August 18, 1998, December 21, 1999, December 28, 2000, August 31, 2001, and September 2, 2003 including its RACM analysis and determination. EPA is also approving the revised enforceable commitments made to the attainment plan for the Baltimore severe ozone nonattainment area which were submitted on December 28, 2000. The enforceable commitments are to submit measures by October 31, 2001 for additional emission reductions as required in the attainment demonstration test, and to revise the SIP and motor vehicle emissions budgets by October 31, 2001 if the additional measures affect the motor vehicle emissions inventory; and to perform a mid-course review by December 31, 2003.

(i) EPA approves the following mobile budgets of Maryland's attainment plan for the Philadelphia area:

(1) [Reserved]

(2) Similarly, EPA is approving the 2005 attainment demonstration and its current budgets because Maryland has provided an enforceable commitment to submit new budgets as a SIP revision to the attainment plan consistent with any new measures submitted to fill any shortfall, if the new additional control measures affect on-road motor vehicle emissions.
