The employment terminations are expected to commence June 8, according to a letter recently sent to Shelbyville Mayor Wallace Cartwright.

Aleris announced last month it will permanently close its Shelbyville alloy plant, located on Railroad Avenue across from Central High School.

In all, 12 salaried employees are losing their jobs along with 44 hourly employees, the letter states.

Four of the workers on salary, an office manager and three process supervisors, have a termination date of July 31. The last day of work for the plant superintendent is "undetermined."

Aleris International, Inc. is headquartered in Beachwood, Ohio, a suburb of Cleveland, and operates 48 production facilities in North America, Europe, South America and Asia, with approximately 8,800 employees.

The Aleris site, which melts down aluminum scrap, has had a succession of different names and owners, including IMCO. At one time, it was owned by Alcan. Later, long after Alcan had sold the aluminum plant, Alcan bought the American Can/Cebal plant on Madison Street.

That plant, which produces plastic tubes for cosmetics, is still owned by Alcan and is not connected with or affected by the Aleris plant.

In 2006, the Aleris plant installed warning sirens in case of a chlorine leak and announced that it had made $2 million in environmental improvements at the site. Some had complained about odors, supposedly from the plant, being smelled on the high school campus.
