Permit issuance for the proposed third runway
On December 13, 2002, the U.S. Army Corps of Engineers issued a federal permit allowing the Port of Seattle to build a third runway at Sea-Tac Airport as part of its Master Plan Update. The project includes an 8,500-foot runway, two Runway Safety Areas, and related construction that will permanently impact nearly 20 acres of wetlands and up to 980 linear feet of Miller Creek. After weighing input from government agencies and the public, the Corps determined the project was not contrary to the public interest and approved the permit. -

EXH AR026434: Highway Runoff Chemistry Hydrology Residence Time Non-Equilibrium Partitioning Heavy Metals Treatment
This research study examines how heavy metals in highway stormwater runoff behave as water flows off pavement, finding that most heavy metals remain dissolved rather than attaching to solid particles due to low alkalinity and short travel times on the pavement surface. The study, conducted on Interstate 75 in Cincinnati over two years, explores how best management practices like detention basins or infiltration trenches could be used to capture these metals before they reach receiving waters. -

EXH 391: Army-EPA MOA – Mitigation Determination Under CWA Section 404(b)(1)
This 2001 Memorandum of Agreement between the U.S. Army and the EPA outlines the policies and procedures for determining what types of mitigation are required when issuing permits for discharging dredged or fill material into waters under Clean Water Act Section 404. It establishes a three-step mitigation sequence — first avoiding impacts, then minimizing unavoidable impacts, and finally providing compensatory mitigation for any remaining harm — with a goal of no overall net loss of wetlands. The document provides guidance to Army Corps of Engineers and EPA field personnel on how to evaluate standard permit applications in compliance with these environmental protection standards.
