The Seattle Tacoma International Airport currently has no air-pollution monitoring system in place. The Washington State Department of Ecology (DOE) studied how seriously the airport is affecting the quality of the air we breathe. The Seattle Tacoma International Airport covers 2500 acres of land in King County. This a mere 0.18% or less than 1/5 of 1% of the land in King County. The DOE found that Sea-Tac Airport contributed 8% of the carbon monoxide and 5% of the nitrogen oxide emissions in all of King County in 1991. The following air pollutants, classified as either Criteria or Toxic http://www.rcaanews.org/ file:///C|/AA_RCAAwebsite/water/libr1.htm Pollutants, are not being monitored by Sea-Tac Airport staff: Total suspended particulates, particulate matter, carbon monoxide, oxides of sulfer, oxides of nitrogen, hydrocarbons, ozone and lead (criteria pollutant) Phenyl, benzene, dioxin, toluene, manganese, xylene, formaldehyde and chloroform pc.,[Ed. note: unreadable text]. Benzene, one of the toxic pollutants, is a known carcinogen. Sea-Tac airport, according to the DOE study, contributed 12.7 tons of benzene in 1984. This amounted to about 0.16 parts per million or 24,000 parts per trillion. New WAC 173-460 proposes the acceptable impact levels for benzene at 0.063 parts per trillion. There is no baseline for a study of air pollution at the Seattle-Tacoma International Airport. There is no system set up at this time to study air pollution. This is a fatal flaw in the [FlightPlan] Environmental Impact Statement which must be corrected. Airport currently has no air-pollution monitoring system in place. [Page 3] Our creation…
