Notes
Memorandum of Agreement (MOA) signed by Port of Seattle, FAA, Washington State Department of Ecology, Puget Sound Air Pollution Control Agency (PSAPCA), and EPA Region 10 establishing a 24-month air quality monitoring program in the Sea-Tac Airport vicinity. The MOA addresses modeled exceedences of the National Ambient Air Quality Standard (NAAQS) for carbon monoxide (CO) identified in the 1996 Final EIS for the Sea-Tac Master Plan Update. Monitoring priorities include CO at roadway intersections, oxides of nitrogen (NOX) near aircraft departure backup queues, ground-level residue from aircraft fuel particle discharges, toxic substances, and fugitive dust from construction. Total funding of $195,000 allocated: Ecology $35K, EPA $30K, Port of Seattle $130K. Port agrees not to proceed with Master Plan Update elements projected to create CO exceedences until monitoring is complete. Field activities scheduled for completion by June 1998. Conformity with Central Puget Sound State Implementation Plan (SIP) is a central concern.
