Sept 16 (Reuters) - Farmer cooperative and grain trader CHS Inc said Thursday it expects its Myrtle Grove, Louisiana, grain export terminal to be operational by the height of the U.S. corn and soy harvest after Hurricane Ida damaged the facility last month.

The exact recovery timeline for the terminal, which unloads grain barges and loads ocean-going vessels for export, remains uncertain, CHA said. The facility remains without power from the local utility provider and repair crews are using an onsite generator, it said. (Reporting by Karl Plume in Chicago)
