U.S. Environmental Protection Agency’s (EPA)’s Proposed Finding that Greenhouse Gas Emissions from Aircraft Cause or Contribute to Air Pollution that may Reasonably Be Anticipated to Endanger Public Health and Welfare, and an Advance Notice of Proposed Rulemaking. Section 231(a)(2)(A) of the Clean Air Act states that, ‘‘The (EPA) Administrator shall, from time to time, issue proposed emission standards applicable to the emission of any air pollutant from any class or classes of aircraft engines which in [her] judgment causes, or contributes to, air pollution which may reasonably be anticipated to endanger public health or welfare.’’
This Proposal explains that in order to issue standards addressing emissions of GHGs from aircraft under section 231, the Administrator must first find that the air pollution being considered may reasonably be anticipated to endanger public health or welfare. The Administrator then must find that emissions of the air pollutant from certain classes of aircraft cause or contribute to that air pollution. This Proposal and the rules to follow that EPA announced in the Advance Notice of Proposed Rulemaking have been found to authorize EPA under the CAA to address greenhouse gas emissions from aircraft to help mitigate climate change.
