In the Final rules section of this Federal Register, EPA is approving the portion of Kentucky's August 26, 2016, SIP revision addressing the NNSR requirements for the 2008 8-hour ozone NAAQS for the Kentucky portion of the Cincinnati-Hamilton, OH-KY-IN Area as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments.
