If states are willing to accept foreign nuclear waste, there's no reason the federal government should prohibit them, says a Utah congressman whose district could get tons of Italian leftovers.

"I don't see it as a federal issue," U.S. Rep. Rob Bishop told The Associated Press.

"If the state of Tennessee wants to take it, and if the state of Utah wants to take it, I'm going to punt it back to them. It is within their purview," the Republican said.

EnergySolutions Inc. wants to import about 20,000 tons of waste from Italian nuclear plants for processing in Tennessee. After processing, about 1,600 tons would be shipped to the company's facility 70 miles west of Salt Lake City — and within Bishop's district —, for disposal. It is the largest and only privately owned radioactive-waste dump in the U.S.

The company's application is at the Nuclear Regulatory Commission, which is taking public comment through June 10.

Bishop differs from U.S. Rep. Jim Matheson, a Utah Democrat who is co-sponsoring a bill that would ban nuclear-waste imports unless it originated in the U.S. or came from an overseas U.S. military facility.

The company's plan has drawn opposition from environmental groups and politicians upset over foreign waste when this country still is trying to deal with its own nuclear waste. South Carolina lawmakers have closed that state's radioactive-waste dump to any waste that doesn't originate from there, New Jersey or Connecticut.

There's concern in South Carolina because the Italian waste could come through the Charleston port.

Bishop is a former lobbyist for Envirocare, EnergySolutions' predecessor, and has received more than $20,000 in contributions from the company's executives and its political action committee since being elected in 2002.

The company also has spent heavily on legislative races and succeeded in taking state lawmakers out of the approval process for accepting more waste than its license allows at the site in Clive, Tooele County.

Matheson's campaign has received nearly $11,000 from the EnergySolutions PAC and executives since 2006.
