A. For all states^a

SIPs must be submitted within 3 years of promulgation of new NAAQS and provide for “implementation, maintenance, and enforcement” of the standard. Among other things each SIP must

• Include enforceable emission limitations and controls as well as schedules and timetables to ensure compliance.

• Provide for the monitoring of ambient air quality.

• Include a program to enforce the emission limitations and control measures.

• Contain adequate provisions prohibiting emissions within the state to contribute significantly to nonattainment of NAAQS in any other state.

• Ensure that the state will have adequate personnel, funding, and authority to carry out the plan.

• Require stationary emission sources to monitor and provide periodic reports of their emissions.

• Meet requirements relating to consultation, public notification, and prevention of significant deterioration of air quality.

• Provide for air quality modeling and provide related data to demonstrate how emissions affect air quality.

• Require owners or operators of major stationary emission sources to pay fees to cover (1) reasonable costs of reviewing and acting upon permit applications, and (2) reasonable costs of implementing and enforcing the terms and conditions of the permit.

• Provide for participation by local political subdivisions affected by the plan.

B. For nonattainment areas^b

Attainment-demonstration SIPs must be submitted within 3 years of an area being designated a nonattainment area. In addition to the items listed in part A, the SIP must

• Provide a plan for the implementation of reasonably available control technologies (RACT) and attainment of primary NAAQS, for the offsetting of emissions of new or modified major stationary sources, and for the installation in major new stationary sources of technology capable of achieving the lowest achievable emission rate (LAER).

• Include a comprehensive emissions inventory for all relevant pollutants.

• Implement a new-source review (NSR) before construction, and for all new or modified stationary sources, implement a permit program that mandates use of control technologies that obtain the LAER and provides sufficient emission offsets from other sources in the area to ensure reasonable progress and attainment of NAAQS.

• Provide for the implementation of contingency measures in the event that the area fails to make reasonable progress or meet its attainment deadline.
