Specifically, EPA is proposing to disapprove the portion of these SIP revisions that the state intended to address contingency measure requirements. Contingency measures are control requirements in a nonattainment area SIP that would take effect should the area fail to meet Reasonable Further Progress (RFP) emissions reductions requirements or fail to attain the NAAQS by the applicable attainment date.
