Water Quality

The Oregon Environmental Quality Commission adopted new water quality standards for the West Division Main Canal near Hermiston, in northeastern Oregon, at their meeting on April 26, 2012. The rule corrects previous standards, establishing designated beneficial uses and associated water quality criteria  that are appropriate for and feasibly attainable in the canal.

On Friday, Nov. 15, 2013, EPA partially approved and partially disapproved the revised standards for Canal. Only the standards changes approved by EPA are effective.
