The Supreme Court ruled on May 25 in a case that questioned the Environmental Protection Agency’s (EPA) ability to regulate wetlands under the Clean Water Act. In a unanimous decision, the Supreme Court affirmed an Idaho couple’s ability to build a home on their property that is a few hundred feet from Priest Lake, reversing a decision made by the U.S. Court of Appeals for the 9th Circuit that sided with the EPA. However, the court was also split within the ruling on what is known as the “significant nexus” test to interpret whether wetlands are connected to navigable waters. The 5-4 majority ruling found that the EPA’s authority applied only to those wetlands that are indistinguishable from and have a “continuous surface connection” to larger lakes, oceans, streams, and rivers. The decision is considered a win for small property owners but significantly reduces protections for wetlands.
