Furthermore, the EPA is approving additional revisions to the 1990 base year emissions inventory submitted as part of the Post-1996 ROP Plan. The EPA is also approving the State's point source banking regulations. This rulemaking action is being taken under sections 110, 301, and part D of the Act.
