The EPA finds Kentucky's arguments On this regard inadequately supported.[132] The Commonwealth involved no long-lasting and enforceable emissions controls in its SIP submission.[133] We provide more reaction to remarks about Kentucky's SIP submission within the RTC document.

See Wisconsin,
This prerequisite is part with the broader set of “infrastructure” specifications, which can be developed to make certain that the structural factors of every point out's air excellent administration software are satisfactory to fulfill the condition's responsibilities beneath the CAA. Disapproving a SIP submission establishes a two-yr deadline with the EPA to promulgate Federal Implementation Strategies (FIPs) to deal with the pertinent necessities, Except if the EPA approves a subsequent SIP submission that satisfies these needs.
