AKRON, Ohio -- The precious metals company that was the source of a cyanide spill that killed more than 30,000 fish in the Rocky River last year has agreed to pay $300,000 in community service payments to the Cleveland Metroparks, according to documents filed in federal court.

The community service deal struck between lawyers for the Kennedy Mint of Strongsville and federal prosecutors will be added to an earlier plea deal, reached in May, that called for the company's owner, Teresina Montorsi of Grafton, to pay $30,893 in restitution to the Ohio Department of Natural Resources. That money will be used to restock the river with 30,000 steelhead trout.

Montorsi, 75, is scheduled to appear later today before U.S. District Judge John Adams, who will be asked to finalize the plea bargains.

The deadly cyanide spill was discovered on April 22, 2012 –- Earth Day -- and eventually traced to the Kennedy Mint, where investigators found an empty 55-gallon drum with a hole punched in the lid.

Federal prosecutors believe Renato Montorsi, Teresina's husband, was responsible for dumping the barrel of cyanide into a storm sewer that led to the Rocky River, causing the massive fish kill. But they dropped the charges against the 79-year-old man after psychiatric tests determined he suffered from dementia and lacked the ability to understand the charges against him or to assist lawyers in his defense. He is not expected to attend today's hearing.

Teresina Montorsi pleaded guilty in May to obstruction of justice, and to federal Clean Water Act violations on behalf of Kennedy Mint. She could receive a sentence of from six months to a year in prison, or Adams could place her on house arrest.

Richard Blake, the company’s lawyer, said Teresina Montorsi was blameless for the fish kill.
