PSAPCA 1992 concerns - Deicing, Roadway Emissions, PoS as lead agency

KI T)A, P CO L''- l) PIERCE COL''- February 18 , 1992 Flight Plan Project Final Reoort DPEIS After a careful review of the Puget Sound Air TransporUt ion Comnuttee's Flight Plan Project Draft Programmatic Environmental Impact Statement we have two major concerns about the adequacy of the air quality element. First , no attempt is made to evaluate the impact of motor vehicle or aircraft emissions on air qual ity in the vicinity of the airport(s). Second , there is no documentation of the methodology or emission factors used to prepare th is report, thus making it impossible to verify the results . Motor vehicle emissions appear to be based solely on the average trip length to the airport(s) from each of the Puget Sound Regional Council's Forecast Analysis Zones . This implies that peoplt: will be able to use the nearest airport to board a flight to their destination; it also completely ignores the impact of traffic congestion on lOC4il air quality . Dispersion modeling is required in order to properly assess this impact and was not conducted. Similarly, the impact of aircraft operations was limited to a cursory evaluation of regional air pollutant emissions. Although the model used to calculate these emissions is also capable of estimating their impact, no dispersion modeling results appear in the report . In addition, existing air quality around the airports was not addressed, even though a comparison between the various flight plan alternatives and present conditions would seem to be fundamental.…
