On April 2, 2017, a discharge occurred from Outfall ODD that was below the minimum pH permit limit of 6.5. Approximately 26,000 gallons of water were discharged to the on-site absorption pond with a pH value between 6.4 and 6.1. The next discharge, which occurred on April 3, 2017, had returned within proper pH limits. The cause of this event was a discharge isolation valve switch malfunction. The switch is being replaced. CNP has not observed any environmental impact from this discharge.
