WASHINGTON — The US Supreme Court  narrowed the scope of the Clean Waters Act in a ruling Thursday.

The ruling overturned the EPA’s Waters of the United States or WOTUS rules introduced in the Obama Administration.

Iowa Senator Chuck Grassley signed onto a brief that urged the High Court to overturn the regulations. Grassley issued a statement saying “thankfully, the Supreme Court saw through this federal overreach and unanimously determined that it violated the Clean Water Act.”

He says after years of uncertainty, the decision is a victory for farmers, builders, landowners and common sense.

Senator Joni Ernst says in a statement that  ‘the federal government has no authority to impose blanket jurisdiction over puddles, waters, and wetlands with vague, overreaching regulations.” She calls it a big win for Iowa.
