EPA Region 10 Letter to FAA Regarding Air Quality Concerns at Sea-Tac Airport Final EIS

Notes

EPA Region 10 supplements its March 18, 1996 comments on the Final Environmental Impact Statement for Proposed Master Plan Update Development Actions at Seattle-Tacoma International Airport, detailing air quality concerns related to conformity with the State Implementation Plan under the Clean Air Act. The letter identifies deficiencies in the draft conformity analysis, noting that the project increases the severity of carbon monoxide exceedances at two intersections near the airport. EPA requests a comprehensive emissions inventory, air quality analysis, mitigation measures, and a cumulative impacts assessment covering multiple projects in the airport area.
