This Spring 1998 newsletter from the Port of Seattle provides an update on the Seattle-Tacoma International Airport FAR Part 150 Aircraft Noise and Land Use Compatibility Study, which aims to reduce the impact of aircraft noise on surrounding neighborhoods. The study involves measuring existing and predicting future noise levels, evaluating noise reduction and land use alternatives, and producing noise exposure maps using the FAA's Integrated Noise Model. Citizens raised key concerns at an initial open house, including adherence to flight tracks, ground noise, and expansion of sound insulation programs, with findings to be presented at a second public open house on July 23, 1998.

Discharge Monitoring Report (DMR) for April 1998, permit number WA-002465-1, discharge number 001 (IWS), submitted by Port Of Seattle for Sea-Tac Airport (facility #681), P.O. Box 68727, Seattle WA 98168. Monitoring period covers April 1–30, 1998. Parameters monitored include flow (GPM), pH, oil and grease (mg/L), TSS (mg/L), BOD5 (mg/L), total glycols (mg/L), and TPH

These documents relate to the 1999 Sea-Tac Airport airfield improvement project, including a haul permit issued to Gary Merlino Construction for trucking rock and concrete along designated routes near the airport, with restricted operating hours during the school year. Also included is a 1998 letter from the Regional Commission on Airport Affairs describing a proposal by Environmental Materials Transport LLC to build a temporary barge terminal near Des Moines Creek Beach Park, with a conveyor system to move fill material to Sea-Tac Airport as an alternative to truck hauling. The materials reflect community and municipal concerns about construction traffic, noise, and environmental impact associated with airport expansion activities in the greater Sea-Tac area.

A March 1998 fax exchange between the Port of Seattle and Herrera Environmental Consultants concerns the scope of work and cost estimates for Third Runway Water Quality Compliance Services. Carlos Herrera of Herrera Environmental sent documents to Port of Seattle contacts Barbara Hinkle and Kym Mattress, arguing that routine project water quality monitoring should be Herrera's responsibility, covering both compliance and BMP performance monitoring. Herrera noted he believed this approach would be most credible to the Washington Department of Ecology and neighboring airport communities, and requested review and discussion of the cost estimates to potentially reduce the budget.

This Home Owner's Instruction Manual was produced under the Port of Seattle's Sound Reduction Program and covers vinyl window and door products installed by CARE-FREE Windows and contractor SKM Construction.

A 1998 internal memo from Ryk Dunkelberg to Richard Kennedy outlines the schedule of eight public CAC/TAC meetings planned through 1999 for the Part 150 Noise Study Update at Sea-Tac Airport, along with broader public engagement activities such as workshops, newsletters, and a project website. The memo also explains the Port of Seattle's cautious policy toward FAR Part 161 aircraft noise regulations, noting that no such studies have ever been successfully approved by the FAA and that pursuing one could jeopardize existing noise abatement programs. Additionally, it addresses the potential acquisition of residential properties in the Approach Transition Areas, stating that no decision has been made and that further study and federal funding would be required.
