(b) Except where the emissions limitations and requirements of an applicable new source performance standard under 40 CFR Part 60 are more stringent than the emissions limitations and requirements of this chapter, any new or modified source issued a permit-to-install after January 1, 2008, shall comply with the requirements of this chapter in effect at the time the source becomes subject to this chapter. For the purposes of this chapter, modified source is as defined in rule 3745-31-01 of the Administrative Code.
