  for Federal Agencies

The conformity process works best when the federal agency coordinates with the applicable state, tribal, or local air quality agency to ensure that the emissions from the existing facility and actions are included in the SIP/TIP. The environmental officials at the federal agencies need to know the process for the development of the SIP/TIP in the area and the appropriate contacts. States, tribes, and local agencies can more effectively accommodate the future action by a federal agency if the agency provides information about the actions to the air quality agency when it is developing a SIP/TIP.

A key to the federal agency’s ability to deal effectively with the state, tribe, or local air quality agency is its knowledge of its own emissions. Development of a comprehensive emission inventory for a federal facility provides the federal agency the information to ensure that all the emissions from a facility are included in the SIP/TIP. The comprehensive inventory can also help identify possible mitigation measures for future conformity demonstrations and ERCs.
