Wash. business groups challenge tribal-backed water protections

A coalition of business associations is challenging federal water quality standards in Washington state, arguing the rules should be repealed. Several Native American tribes, including the Quinault Indian Nation and Puyallup Tribe, support the regulations, citing treaty-protected fishing rights and environmental protections. The U.S. Environmental Protection Agency defends the standards, saying they protect public health. The case, filed in D.C. federal court, could impact water policies nationwide.
