New York Times:

In a major victory for environmental advocates, New York State has ruled that outmoded cooling technology at the Indian Point nuclear power plant kills so many Hudson River fish, and consumes and contaminates so much water, that it violates the federal Clean Water Act.
The decision is a blow to the plant’s owner, the Entergy Corporation, which now faces the prospect of having to spend hundreds of millions of dollars to build stadium-size cooling towers, or risk that Indian Point’s two operating reactors — which supply 30 percent of the electricity used by New York City and Westchester County — could be forced to shut down.
Entergy officials said that they were “disappointed” in the ruling and that they might fight it in court. The original federal licenses for the two 1970s-era reactors expire in 2013 and 2015, and a water quality certificate is a prerequisite for a 20-year renewal by the United States Nuclear Regulatory Commission. But a prolonged appeal in New York could delay a shutdown, Diane Screnci, a spokeswoman for the commission, said late Saturday.
An Entergy spokesman said that converting Indian Point’s cooling system would cost $1.1 billion and would require shutting both reactors down entirely for 42 weeks.
The ruling in New York comes after President Obama pressed for the construction of new nuclear plants in his State of the Union address. But it is the second instance since of a state asserting its power to threaten an existing nuclear plant. In Vermont, the State Senate voted overwhelmingly in February to block operation of Entergy’s Vermont Yankee plant after 2012, citing leaks of radioactive tritium, inaccurate testimony by company officials and other problems.
Nuclear proponents said they hoped that the federal government would determine that the nation’s energy needs should take precedence over such state-level actions. “The N.R.C. may decide this is not a policy they’re going to give credence to,” said Arthur J. Kremer, chairman of the New York Affordable Reliable Electricity Alliance, of which Entergy is a member. “It’s bad news for investors in new power facilities and in upgrading old ones.”

Shut down 30 percent of NYC and Westchester’s electricity? It’s almost as if someone wants our electricity rates to skyrocket.
