WASHINGTON (AP) - Democrats have blocked a Senate bill that would have forced the Obama administration to withdraw new federal rules to protect smaller streams, tributaries and wetlands from development and pollution.
Supporters of the legislation - and opponents of the rules - did not get the 60 votes needed Tuesday to stop debate and consider the bill. The vote was 57-41, meaning Democrats have blocked the bill, for now.
Most Democrats say the Obama administration rules will safeguard drinking water for 117 million Americans and should remain in place. The White House threatened a veto of the bill, saying the regulations are "essential to ensure clean water for future generations."
Republicans and a handful of Democrats from rural states say they fear a steady uptick in federal regulation of every stream and ditch. Senate Majority Leader Mitch McConnell, R-Ky., said on the Senate floor that the regulations are "a cynical and overbearing power grab dressed awkwardly as some clean water measure."
Four Democrats voted with Republicans on the measure - Sens. Heidi Heitkamp, of North Dakota, Claire McCaskill, of Missouri, Joe Manchin, of West Virginia, and Joe Donnelly, of Indiana.
Federal courts have already put the rules on hold as they consider a number of lawsuits that were filed immediately after the Environmental Protection Agency and the U.S. Army Corps of Engineers issued the regulations in May.
The rules clarify which smaller waterways fall under federal protection after two Supreme Court rulings left the reach of the Clean Water Act uncertain. Those decisions in 2001 and 2006 left 60 percent of the nation's streams and millions of acres of wetlands without clear federal protection, according to the EPA, causing confusion for landowners and government officials.
The EPA says the new rules would force a permitting process only if a business or landowner took steps that would pollute or destroy the affected waters - those with a "direct and significant" connection to larger bodies of water downstream that are already protected. For example, that could include tributaries that show evidence of flowing water.
The Senate bill would force the EPA to withdraw and rewrite the rules. Democratic supporters of the regulations say that would just cause even more confusion.
"We shouldn't pass legislation that would create even more uncertainty and invite years of litigation," said Sen. Barbara Boxer, D-Calif.
