Since the State Implementation Plan (SIP) mandated in nonattainment areas must comply with specific federal requirements, isn the EAC weaker?
The plan developed under the EAC will be incorporated into the SIP and will therefore be state and federally enforceable. As such, the EAC will comply with the same federal requirements as any other SIP. The EAC protocol also includes SIP provisions more stringent than in the standard nonattainment process (semi-annual tracking and reporting, maintenance for growth). In addition, the EAC will result in a local clean air plan three years earlier than expected under standard nonattainment (2004 versus 2007).
