(Salem, OR) -- Oregon is joining a 21-state coalition in a lawsuit against the Trump Administration for weakening federal regulations on mercury and other pollutants released by coal and oil-fired power plants. Oregon Attorney General Dan Rayfield says the decision to rollback 2024 standards allows power plants to release more dangerous chemicals into the air, which travel across state lines and settle into waterways. The coalition says the repeal was illegal because the Environmental Protection Agency failed to provide a reasoned basis for its decision, nor did it adequately consider the consequences.
