Petitions to the Office of Air and Radiation

This page makes available petitions for rulemaking received by the Office of Air and Radiation on or after January 1, 2013. For the purposes of this page, the agency has posted incoming communications styled as "petitions" for generally applicable, national rulemakings. Petitions provided as comments in a publicly available rulemaking docket are not reproduced here. Petitions for reconsideration of rules recently issued under the Clean Air Act are also not included. Additional petitions will be added on an ongoing basis as they are received or identified; petitions on this page were last updated in November 2022.

The presence of a petition on this page does not indicate an EPA decision to grant or deny the petition. Any regulatory action that follows as a result of a petition for rulemaking would still be shaped by the typical outreach used by the agency to gather stakeholder input, and is still subject to any applicable notice and comment requirements. Petitions for rulemaking from other offices.
