An energy company has resumed production at an ethanol plant in Indiana along the Ohio River that was shut down more than two years ago by its previous owner, The Associated Press reported yesterday. Valero Renewable Fuels said that the plant at the Port of Indiana-Mount Vernon was operating with about 65 employees. The plant, located 20 miles west of Evansville, Ind., was closed due to a decline in the ethanol market in 2012. Company officials cited the plant's access to corn suppliers, as well as strong rail, truck and barge transportation. San Antonio-based Valero bought the plant in March from Pekin, Ill.-based Aventine Renewable Energy. The Indiana Economic Development Corp. offered Valero up to $600,000 in tax credits based on its hiring plans.
