Bill > HR2351

This bill directs the Federal Aviation Administration (FAA) to contract the National Academy of Sciences to conduct a national study on the characteristics, distributions, sources, and potential health effects of airborne ultrafine particles (UFPs), which are particles with diameters less than or equal to 100 nanometers. The study will focus on large hub commercial airports in specific metropolitan areas and identify measures, including the use of sustainable aviation fuels, intended to reduce emissions from aircraft and airport operations and assess potential impacts on emissions related to UFPs. The FAA is required to submit a report on the study to Congress within 2 years of executing the funding agreement with the National Academy of Sciences.
