subsequent revision to an air quality control measure proposed 
under Subsection (b) that directly affects or requires action of a 
significant portion of the general population of a participating 
county only if the governing bodies of both the participating 
county and the most populous municipality that has a majority of the 
municipality's residents residing in the participating county 
request or consent to the measure as part of an early action plan.
