Table 4 Stormwater Quality Comparators comparing water quality data across multiple study sites including NURP 1983, BURP 1984, Metro 1982, Bellevue 1995, Highway Runoff 1981, Portland NPDES 1993, and STIA Landside and Airfield locations. Parameters measured include pH, TPH, fecal coliforms, BOD5, TSS, turbidity, glycols, copper (Cu), lead (Pb), and zinc (Zn) in units of

This document is a technical laboratory reference table listing method detection limits (MDLs), practical quantitation levels (PQLs), and published water quality values for a wide range of chemical compounds in various water matrices, including wastewater, groundwater, and drinking water. It compares laboratory PQL ranges against Method B groundwater and surface water standards for chemicals such as acenaphthene, acrolein, aldrin, arsenic, benzene, and PCB compounds. The table is used to assess whether analytical detection capabilities meet regulatory thresholds for water quality monitoring purposes.

In September 2002, the Port of Seattle notified nearby residents that it would be removing trees located west and south of Tyee Golf Course, near South 196th Street, at the direction of the Federal Aviation Administration. The trees were identified as hazards to aircraft taking off and landing at Seattle-Tacoma International Airport. Work was scheduled to begin September 16, 2002, and was expected to last up to four weeks.

Port Of Seattle petition for judicial review filed in King County Superior Court (case no. 02-2-25658-9SEA) under RCW 34.05 (Administrative Procedure Act), challenging the August 12, 2002 final order of the Pollution Control Hearings Board (PCHB Case No. 01-160) regarding the 401 Certification issued by Washington Department of Ecology on September 21, 2001 for the

This August 2002 permit application by the Port of Seattle outlines proposed Master Plan Update improvements at Seattle-Tacoma International Airport, including the construction of a third runway, expanded taxiways, cargo facilities, and terminal upgrades. The documents map both on-site and off-site wetland mitigation areas required to offset environmental impacts, with retaining walls and creek relocations used to minimize effects on wetlands and Miller Creek. The project spans multiple sections of King County, Washington, and includes detailed plans for stormwater detention, runway safety areas, and property acquisition boundaries.

This document is the Final Report (July 2002) of the FAR Part 150 Study Update for Seattle-Tacoma International Airport, a federally guided process to assess and manage aircraft noise impacts on surrounding communities. Technical Appendix Two (Appendices 7–26) compiles key study materials including community advisory committee reports, land use recommendations, flight track analyses, public hearing transcripts, noise data, and Port of Seattle resolutions. The report represents the culmination of extensive community involvement and technical review aimed at updating the airport's noise abatement and sound attenuation programs.

This document is the Technical Appendix One of the Seattle-Tacoma International Airport FAR Part 150 Study Update Final Report, completed in July 2002. It compiles community and technical advisory committee records, public hearing transcripts, noise abatement recommendations, and land use findings gathered during the airport's noise compatibility study. The report was produced by the Barnard Dunkelberg & Company Team on behalf of the Port of Seattle's Noise Abatement Office.

This document outlines the FAA's approval decisions on the Noise Compatibility Plan (NCP) for Seattle-Tacoma International Airport (Sea-Tac), as reviewed in June 2002. It covers a range of proposed measures to reduce aircraft noise, including public oversight committees, noise barriers, runway use preferences, and a Fly Quiet Program, with some measures approved, others partially approved, and several disapproved pending additional information. The plan aims to balance noise reduction for surrounding communities with the safe and efficient operation of the airport.

This document is the FAR Part 150 Noise Compatibility Program Study Update for Seattle-Tacoma International Airport (Sea-Tac), approved by the FAA in June 2002. It outlines a series of measures aimed at reducing aircraft noise, including establishing a public oversight committee, exploring noise barriers and ground run-up enclosures, and encouraging the voluntary phase-out of older, louder Stage 2 jet aircraft. The FAA approved some measures outright, while others—such as revised maintenance run-up regulations and the voluntary aircraft phase-out—were disapproved pending submission of additional supporting information.
