LOS ANGELES (AP) — California regulators are recommending $94 million in refunds for Southern California utility customers for reduced operating costs at the now-closed San Onofre nuclear power plant.

The California Public Utilities Commission said in a statement Tuesday that the costs were “neither reasonable nor necessary” and are only a first step.

The agency is considering hundreds of millions of dollars in possible refunds for problems at the plant run by Southern California Edison.

It was shut down in January 2012 after a small radiation leak led to the discovery of damaged tubing.

Edison closed the plant for good earlier this year.

The commission will consider the refunds recommended by agency judges next month.
