In EPA's adequacy review, the Agency determines whether the motor vehicle emissions budgets in the SIP are adequate for conformity purposes. More information about the adequacy review process is available in EPA's May 14, 1999, guidance, available on the Policy and Guidance page.

For additional information on adequacy review, review these questions:

• What SIP submissions are currently under EPA adequacy review?
• What SIP submissions has EPA already found adequate or inadequate?
• Who do I contact to be notified when EPA receives a particular SIP submission?

For questions regarding a particular SIP or state, contact your EPA Regional contact person.
