Memorandum of Agreement (MOA) between the U.S. Department of the Army and the U.S. Environmental Protection Agency (EPA) articulating policy and procedures for determining type and level of mitigation required under Clean Water Act (CWA) Section 404(b)(1) Guidelines. AR037425. Covers three mitigation types: avoidance, minimization, and compensatory mitigation; establishes no net loss of wetlands goal;

Direct testimony of Erik Stockdale, Senior Wetlands Specialist at Washington State Department of Ecology, submitted in PCHB No. 01-160 before the Pollution Control Hearings Board. Stockdale, a certified Professional Wetlands Scientist, evaluates wetland impacts from Port Of Seattle Master Plan Update projects at Seattle-Tacoma International Airport (STIA). Project will fill 18.37 acres of palustrine freshwater

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.

Letter and memorandum from EPA Assistant Administrator Robert Perciasepe transmitting the final Interim Permitting Approach for Water Quality-Based Effluent Limitations in Storm Water Permits to State Water Program Directors and EPA Water Management Division Directors. The policy addresses NPDES storm water permit effluent limitations, adopting best management practices (BMPs) in lieu of numeric water quality-based

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.

In this 2001 declaration filed with Washington State's Pollution Control Hearings Board, fisheries biologist Dr. John A. Strand argues that proposed modifications to the Port of Seattle's stormwater discharge permit would harm Walker and Gilliam Creeks near Sea-Tac Airport, which support salmon, trout, and other aquatic life. Dr. Strand contends that Ecology failed to identify specific locations of new construction-related stormwater outfalls, denying the public a meaningful chance to assess environmental impacts. He supports a stay of the permit modification until its compliance with the Clean Water Act can be fully reviewed.
