Prefiled direct testimony of Steven J. Swenson, licensed civil engineer at R.W. Beck, submitted in PCHB No. 01-160, Airport Communities Coalition (ACC) and Citizens Against Sea-Tac Expansion (CASE) v. State of Washington Department of Ecology and Port Of Seattle. Swenson testifies on stormwater management at SeaTac International Airport (STIA) during construction and operation of Master

This technical report documents VS2DT, a computer program that models how chemical solutes move through variably saturated porous soil and rock, accounting for processes such as advection, hydrodynamic dispersion, decay, adsorption, and ion exchange. The document includes the underlying mathematical theory, numerical methods, data input instructions, and verification problems comparing the program's results against known analytical solutions. While primarily a groundwater contaminant transport modeling tool, it has no direct connection to airport noise policy.

NPDES Permit WA-002465-1 fact sheet for the Seattle-Tacoma International Airport (STIA), issued to the Port Of Seattle. Establishes basis for effluent limitations and requirements for discharge of treated industrial wastewater to Puget Sound (WA-PS-0270) and stormwater to Miller Creek (WA-09-2005), Des Moines Creek (WA-09-2000), and the City of SeaTac storm sewer, tributary to Gillian Creek

Prefiled testimony of Dr. Michael Riley, Civil Engineer, in PCHB No. 01-160, Airport Communities Coalition (ACC) v. State of Washington Department of Ecology and Port Of Seattle. Riley performed modeling analysis of fill criteria in the 401 Certification for the Third Runway embankment at Sea-Tac Airport, using conservative assumptions including maximum metal concentrations allowed by

This document presents chemical composition data for various petroleum fuel types, including fresh gasoline, weathered gasoline, fresh diesel, weathered diesel, and heavy fuel oil. It breaks down the percentage and concentration (mg/kg) of aliphatic and aromatic hydrocarbon fractions across different carbon chain length ranges. The data appears to support environmental modeling and site assessment work, likely related to fuel spill or contamination analysis.
