=i-e-Tacoma International Airport (Sea.-Tac) Expansion Project Environmental mp,ICt Statement-- The Port of Seattle completed and issued its Final Supplemental ,nvironmental Impact Statement for the proposed Master Plan Update at Sea-Tac. followed by the Federal Aviation Administration's release of its Record of Decision and Air Conformity determination. The FM determined that the project will not be considered regionally sigIdficant with regard to air pollution emissions, and that it is consistent with the State Implementation Plan ,r dir quality. The state reaffirmed its certification of the Sea-Tac Airport third runway project is certification is conditioned to assure that the third runway will be constructed and operated in compliance with applicable air and water quality standards. The conditions of the ,rtification uld the status of the environmental permits to be issued by the Department of ,c.ojogy (Ecology) are explained in more detail below. Ecology is one of several agencies that reviewed both the environmental impact statement (EIS) and the supplemental EIS for the proposed airport expansion project. and is involved in issuing environmental permits and ,ertifications for the project , Stockpile of fill material '-- The Port has begun to stockpile fill needed to build the third runway. CWTently, the fill is coming from a permitted spd and gravel mine located in Dupont. The fill is shipped by barge up the Duwamish River and then trucked up SR509 to the airport. , Enforcement – Ecology recently penalized the Port for improperly controlled soil erosion runoff from an employee parking lot under construction north…

The study - done at the re- quest of 33rd District state Rep. Greg Fisher (D-Des Moines) - indicates that the airport accounts for approxi- mately 8 percent of the carbon monoxide ·and 5 percent of the nitrogen oxide in King Coun- ty. Both substances are suspected carcinogens, which means they may cause cancer. "Those who live around the airport live in an air-pollution ~------------v_o_t_~ __ N_o_._12_7 ____ ~IIL ___________________________ A __ 3~ NORTH HILL SOUTH SEATAC NORMANDY PARK ~s a major polluter · hotspot," said Fisher. "It could have significant impacts on their health." POLLUTION GENER· ATED by the airport may be transported by the wind, transformed in the atmosphere and then deposited in sur- rounding areas, the report said. Taken in the aggregate, au- tomobiles still produce far more pollution than any other source, including the airport, said Jim Nolan of the Puget Sound Air Pollution Control Agency in Seattle. "But you're going to find that the airport is a great pollution producer, partly because so many vehicles travel there," Nolan said. "But in a lot of respects, au- tomobile traffic is much worse than air traffic." The Boeing plant in Renton, for example, generates 11 tons of carbon monoxide and 45 tons of nitrogen oxide each year, Nolan said. The · airport gel'lerates 3,628 tons of carbon monoxide and 1,897 tons of nitrogen oxide annually, according to the report. Automobiles in King County generate 322,037 tons of carbon monoxide annually, according to statistics from the air-pollution control…
