Proposed Finding That Lead Emissions From Aircraft Engines That Operate on Leaded Fuel Cause or Contribute to Air Pollution That May Reasonably Be Anticipated To Endanger Public Health and Welfare; (29 page(s), in English)

Proposed action - In this action, the Administrator is proposing to find that lead air pollution may reasonably be anticipated to endanger the public health and welfare within the meaning of
section 231(a) of the Clean Air Act. The Administrator is also proposing to find that engine emissions of lead from certain aircraft cause or contribute to the lead air pollution that may reasonably be anticipated to endanger public health and welfare under section 231(a) of the Clean Air Act. Entities potentially interested in this proposed action include those that manufacture and sell covered aircraft engines and covered aircraft in the United States and those who own or operate covered aircraft. Covered aircraft engines in this context means any aircraft engine capable of using leaded aviation gasoline as well as all aircraft and ultralight vehicles equipped with covered engines. The proposed findings in this action, if finalized, would not themselves apply new requirements to entities other than the EPA and the Federal Aviation Administration (FAA).
