1. Short title This Act may be cited as the Protecting Airport Communities from Particle Emissions Act . 2. Study on ultrafine particles (a) In general The Administrator of the Federal Aviation Administration shall conduct a study that— (1) includes a review of the results of previous studies on ultrafine particles in the air, including the health impacts of such particles; (2) for each of the 20 largest airports in the United States (as measured by calendar year 2016 revenue enplanements), analyzes and evaluates with respect to the communities surrounding, near, and impacted by airport-generated air traffic— (A) the ultrafine particles present in the air; (B) the characteristics of such particles; (C) the spatial distribution patterns and concentration of such particles; (D) the primary sources of such particles; (E) the contributions made by aircraft to such particles relative to other primary sources; (F) the health impacts of such particles, including with respect to heart and lung diseases, asthma rates, nervous system disorders, and any other impacts observed in or suggested by previous studies reviewed under paragraph (1); and (G) disproportionate rates of exposure, risks, and other negative impacts on communities of color, economically insecure residents, vulnerable groups, and disparately impacted communities; and (3) analyzes the potential impacts of mitigation options, emissions reductions, and the increased use of aviation biofuels with, or in place of, commonly used petroleum-based aviation fuels on— (A) ultrafine particles in the air surrounding airports
