Air Quality Criteria Pollutant Emissions Inventory Task 2.8: Working Paper – Documentation of Assumptions

Document Library
SAMP

This 2016 working paper documents the methods and assumptions used to build an air quality emissions inventory for Seattle-Tacoma International Airport as part of the Sustainable Airport Master Plan. Using the FAA's EDMS modeling software, analysts estimated pollution from sources including aircraft engines, ground support equipment, parking, and stationary facilities such as generators and boilers. Aircraft operation data for 2014 was gathered from multiple sources, including FAA tower records, airline guides, and the Port of Seattle's own noise monitoring system.

Notes

LeighFisher (LFA) working paper documenting assumptions for the Air Quality Criteria Pollutant Emissions Inventory (Task 2.8) developed for Seattle-Tacoma International Airport as part of the Sustainable Airport Master Plan (SAMP). Uses FAA EDMS Version 5.1.4.1 to estimate 2014 baseline emissions of criteria pollutants from aircraft engines, auxiliary power units (APUs), ground support equipment (GSE), stationary sources (generators, commercial kitchens, cooling towers, boilers, bulk liquid storage tanks), parking traffic, and roadway traffic. Data sources include Port of Seattle Airport Statistics, FAA ATCT records, FAA ASPM, ANOMS, OAG, and JP Airline Fleets International. Temperature inputs from NCDC Climate Normals 1981–2010; default EDMS mixing height of 3,000 feet used. Aircraft operation categories covered: Air Carrier, Air Taxi, General Aviation, and Military. Notes FAA released AEDT Version 2b after study initiation.
