Santa Fe, NM --- Attorney General Hector Balderas today, joined a coalition of 19 attorneys general, in filing a lawsuit challenging the Trump Administration’s unlawful final rule redefining the "waters of the United States" under the Clean Water Act. The final rule continues the Environmental Protection Agency’s (EPA) effort to weaken water quality protections under the Clean Water Act and narrow the definition of “waters of the United States.” The new rule removes protections for all ephemeral streams, many wetlands, and other waters that were previously covered under the Act. In the lawsuit, the coalition argues that EPA’s rule directly conflicts with the text of the Clean Water Act, Supreme Court precedent, and the EPA’s own scientific findings.
