1. Short title This Act may be cited as the Protecting Airport Communities from Particle Emissions Act . 2. Airborne ultrafine particle study (a) In general Not later than 180 days after the date of enactment of this Act, the Administrator of the Federal Aviation Administration, jointly with the Administrator of the Environmental Protection Agency, shall enter into an agreement with an eligible institution of higher education to conduct a study examining airborne ultrafine particles and their effect on human health. (b) Scope of study The study conducted under subsection (a) shall— (1) summarize the relevant literature and studies done on airborne ultrafine particles worldwide; (2) focus on large hub commercial airports in— (A) Seattle; (B) Boston; (C) Chicago; (D) New York; (E) the Northern California Metroplex; (F) Phoenix; (G) the Southern California Metroplex; (H) the District of Columbia; and (I) Atlanta; (3) examine airborne ultrafine particles and their effect on human health, including— (A) characteristics of UFPs present in the air; (B) spatial and temporal distributions of UFP concentrations; (C) primary sources of UFPs; (D) the contribution of aircraft and airport operations to the distribution of UFP concentrations when compared to other sources; (E) potential health effects associated with elevated UFP exposures, including outcomes related to cardiovascular disease, respiratory infection and disease, degradation of neurocognitive functions, and other health effects, that have been considered in previous studies; and (F) potential UFP exposures, especially to susceptible and vulnerable groups; (4) identify measures, including the use of sustainable aviation fuels, intended to reduce emissions from aircraft and airport operations and assess potential effects on emissions related to UFPs
