Air Quality Planning Documents

MPD Air Quality Team is responsible for implementing and developing the statutory and regulatory requirements for conformity state implementation plans (conformity SIPs). A conformity SIP includes a state’s specific criteria and procedures for certain aspects of the transportation conformity process. Clean Air Act section 176(c) is the statutory authority for transportation conformity (42 U.S.C. 7506(c)). The regulations that explain the requirements for a conformity SIP are found at 40 CFR 51.390 which was updated January 24, 2008 (73 FR 4420).   NOTE: MPD Air Quality is currently in the process of updating these consultation procedures and process - the older processes are provided below for informational purposes only.
