General Conformity Training Module 1.4: More Information
1.4.1 Revisions to the General Conformity Regulations
EPA initially promulgated the General Conformity regulations in January 1994. Subsequently EPA collected information from other federal agencies on how to maintain the same environmental protections while streamlining the General Conformity implementation process. This information was used to develop and propose revisions to the General Conformity rule. After soliciting comments on these revisions from the public, EPA issued a final rule revision on April 5, 2010. This 2010 revised rule improved the process federal entities use to demonstrate that their actions will not contribute to a NAAQS violation, provided tools to encourage better communication and air quality planning between states and federal agencies, and encouraged both the federal agencies and the states to take early actions to ensure projects will conform to the state’s plans to implement the NAAQS. The 2010 revised General Conformity regulations and additional information are available on EPA's General Conformity website at https://epa.gov/general-conformity.
