This page is an attempt to solve a problem we’ve had since the beginning: how to get visitors to study documents and all the related content which often provides the necessary context. For example, most studies are meant to be read by specialists. If you are a layperson, you may only be interested in the ‘one-pager’. This page shows you both.
This page last reviewed March 12, 2015 This website contains information pertaining to the Harbor Communities Monitoring Study (HCMS), conducted to characterize air quality in the communities of the greater Wilmington area. The air pollution measurement phase occurred during 2007. The primary goal of this study is to characterize the spatial variations in air

This statement is submitted for review pursuant to the requirements of Section 102(2)(C) of the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq); E.O. 11990, Protection of Wetlands; E.O. 11998, Floodplain Management; the USC Subtitle VII; 42 U.S.C. 7401 et seq; 49 U.S.C. 47101 et seq; Washington State Environmental Policy Act (RCW 43.210); and other applicable laws. The proposed action will impact the 100-year floodplain as indicated on the Federal Emergency Management Agency's Flood Insurance Rate Map. This Environmental Impact Statement (EIS) is a combined National Environmental Policy Act and Washington State Environmental Policy Act (SEPA) docunient. With regard to SEPA requirements, this EIS represents the second step of a phased environmental review which began with publication d the 1992 Flight Plan Final EIS, which assessed alternatives for addressing regional aviation needs. This Final EIS also contains the draft conformity statement, as required by the Clean Air Act amendments. The Port of Seattle, operator of Seattle-Tacoma International Airport, has prepared a Master Plan Update for the Airport. The Plan shows the need to address the poor weather operating capability of the Airport through the development of a third parallel runway (Runway 16W34X) with a length of up to 8.500 feet, separated by 2,500 feet from existing Runway 16U34R, with associated taxiways and navigational aids. Other development needs include: extension of Runway 34R by 600 feet; establishment of standard Runway Safety Areas for Runways 16Rl34L and 16U34R; development of a new air traff~c control tower; development of a…

Re: Flight Plan: Non-Project (Programmatic) Final Environmental Impact Statement (FEIS) Dear Reader:. The central Puget Sound region is faced with growing demand for commercial air the existing Seattle-Tacomatransportation services and a limited capacity at _ • " Sea Tac Without :_n_ionof " ort ca acity or other steps toInternaUon_..Airport.( .- ). exp ;- . _ .p ....... address the increase m m_d-to long-range travel neeos, me result wu/o.e oetays .mrmr travelers, which could ultimately affect the region's economy. The soluuon to this challenge must strike a balance between environmental impacts, quality of life faaors, and the travel needs of the region's populace. The Flight Plan Project has been a joint effort of the PugetSound RegionalCouncil and the Port of Seattle. The project was initiated bythe Puget bouno _oundl ox Governments (predecessor to the Puget Sound Regional Council) and the Port of Seattle to research airpon system alternatives to meet the region's long-term air transportation needs. (On October 1, 1991 the Puget Sound Council of Governments (r_L._u) was dissolved and replaced by the Puget Sound Regional Coundl.) The PSCOG ano me Port established the Puget Sound Air Transportation t_ommittee (PSATC), whi_ was composed of citizens, elected officials and private sector interests, to propose solutions to the region's air transportationneeds. The Flight Plan s Draft Report, prepared by the Re_ionaJ Council and the Port of Seattle and issued on January 7, 1992, included a.non- project, draftenvironmental impact statement (DEIS) re_gardingthe PSATC's ad_ ory recommendations.
