This 1997 Annual Stormwater Monitoring Report, prepared by Scott Tobiason of Port of Seattle Environmental Services, documents water quality data collected from Seattle-Tacoma International Airport's stormwater discharges between July 1, 1996 and May 31, 1997. The report analyzes discharge samples from stormwater outfalls across the airport's drainage basins, comparing results to regional and national benchmarks, and notes that improvements from newly installed Best Management Practices (BMPs) would be evaluated in the following year's report. It was submitted to the Washington Department of Ecology in fulfillment of Special Condition S.9 of the airport's NPDES permit.

This 1997 report by Science Applications International Corporation characterizes sediment quality in the Duwamish Turning Basin near Seattle, Washington, as part of the Hamm Creek Restoration Project. It presents results from chemical testing, biological bioassays, and sediment sampling to evaluate contaminant levels and compare them against sediment management standards. The study was prepared for the U.S. Army Corps of Engineers, Seattle District.

This document contains aerial photographs of Seattle-Tacoma International Airport (Sea-Tac) taken in 1997 and 1998 by Walker & Associates, a photogrammetric and GIS services firm based in Seattle, WA. The images show the airport's runways, taxiways, terminal area, and surrounding residential and commercial neighborhoods from above. Accompanying metadata indicates the 1997 photograph was taken on August 31, 1997, at an approximate print scale of 1 inch equals 2,300 feet, under negative number 1197 SeaTac PP-2.

A June 1997 transmittal from the Port of Seattle Engineering Department to Alaska Airlines' Peggy McCloskey forwards final bid bioassay results for the Arco Hoecust Safewing MP IV 1957 Green product. The enclosed Laboratory Report from Bio Research Laboratories, Inc. documents an Acute Oral Rat Toxicity Test performed for MultiChem Analytical Services, testing the Green Safewing MP IV substance at a dose of 5000 mg/kg. The report, dated May 21, 1997, was directed by Warren C. Ladiges, DVM, and signed off by President and Scientific Director John J. Majnarich, Ph.D.

This June 1997 report, prepared by the Port of Seattle for Washington State's Department of Ecology, presents storm water receiving environment monitoring results conducted under NPDES Permit No. WA-002465-1. It covers water quality topics including instream toxicity bioassays, sediment quality, identification of pollution sources, metals speciation, vegetation management, and streambank erosion in Miller Creek and Des Moines Creek watersheds near Sea-Tac Airport. The findings assess the environmental impact of airport storm water runoff on local waterways and identify contributing pollution sources within each creek basin.
