A local oil refinery is planning a multi-million dollar expansion. Ergon Incorporated, located in Newell, will invest 78 million dollars in upgrades that will allow the refinery to process new crude oils from the Marcellus and Utica shales in the Ohio Valley. Ergon Spokesman Jim Temple said the expansion primarily involves processing equipment and won't create any new jobs. The plant employs 180 people. The expansion is expected to be completed in 2014.
