Notes
Myths and Facts document dated August 30, 2002 addressing airport and aircraft air quality issues. Covers particulate matter (PM2.5, PM10), VOCs, NOx, ozone, carbon monoxide, and carcinogens from airport emissions. Discusses ICAO aircraft engine emissions certification standards, the ‘smoke number’ standard, EDMS (Emissions Dispersion Modeling System), ISC3 and AERMOD dispersion models, FAA regulatory authority over airports, USEPA limitations, and shoreline pollution trapping via sea/lake breeze effects. Notes that ICAO — not USEPA — regulates aircraft engine emissions, and that FAA’s EDMS model switch from ISC3 to AERMOD reduced prediction conservatism by a factor of approximately 12:1. Also addresses noise abatement terminology and sound insulation programs.
