This EPA report summarizes U.S. greenhouse gas emissions data from 1990 to 2015, showing that total emissions reached 6,587 million metric tons of CO2 equivalent in 2015, a 2.3% decrease from 2014 levels. Carbon dioxide makes up the largest share at 82% of emissions, with electricity generation and transportation being the biggest contributing economic sectors at 29% and 27% respectively. The report includes detailed emissions breakdowns by gas type, economic sector, and fuel source, along with unit conversion tables and global warming potential values for reference.

A compilation document containing Washington State’s Model Toxics Control Act regulation (Chapter 173-340 WAC), the Model Toxics Control Act statute (Chapter 70.105D RCW), and the Uniform Environmental Covenants Act (Chapter 64.70 RCW). Published by the Washington State Department of Ecology’s Toxics Cleanup Program as Publication No. 94-06, revised in 2013.

This April 2004 report by the League of Women Voters examines air quality in the Puget Sound region, tracing the history of air pollution regulation from King Edward I's coal ban in 1305 through the creation of the U.S. Environmental Protection Agency in 1970. It focuses on the role of the Puget Sound Clean Air Agency in monitoring and reducing local air pollutants, with particular attention to small particles and diesel emissions. The report provides background on federal clean air legislation and outlines the League's related policy positions.

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;

EPA Integrated Risk Information System (IRIS) QuickView pages for Antimony (CASRN 7440-36-0) and Arsenic, inorganic (CASRN 7440-38-2), accessed February 14, 2002. Antimony oral RfD is 4×10-4 mg/kg-day based on LOAEL of 0.35 mg/kg-day from Schroeder et al. 1970 rat chronic oral bioassay; confidence rated Low. Arsenic oral RfD is 3×10-4 mg/kg-day based on NOAEL of

A scientist retained by the Airport Communities Coalition wrote to the EPA in December 2000, raising serious concerns about the Port of Seattle accepting contaminated fill materials for the proposed Third Runway project at Seattle-Tacoma International Airport. The letter argues that the Port improperly used Washington State's Model Toxics Control Act (MTCA) cleanup standards as fill acceptance criteria, when those standards were designed to clean up existing contaminated sites, not to permit introducing pollution onto previously clean land. The scientist also criticizes the Port's soil testing methods as statistically inadequate to detect the true extent of contamination, warning that chemicals in the fill could leach into groundwater, wetlands, and surface water including Miller Creek.

EPA report (EPA 821-R-00-001, January 2000) presenting a preliminary data summary of airport deicing operations. Covers aircraft and pavement deicing/anti-icing fluids including ethylene glycol-based compounds, fluid types, fluid application methods, variables affecting fluid use, nonchemical deicing methods, and NPDES/Clean Water Act wastewater concerns. Data collected via 1993 screener questionnaire, airport/vendor/POTW mini-questionnaires, EPA site visits, EPA

Article by John C. Hall, William T. Hall, and Charles J. Simmons published in Water Environment & Technology (June 1997) arguing that EPA’s 1984 and 1993 copper water quality criteria should not be applied directly to municipal effluents (POTWs) because dissolved copper in biologically treated effluents is complexed with organic and inorganic matter and is
