It flooded the trench and proceeded to flow into a nearby storm grate. The facility staff revised the initial estimate and determined that a  discharge of approximately 1000 gallons entered the storm grate.  The PEW pumps were shutoff at 10:54 am.  Sandbags were deployed around the storm grate to prevent further drainage.  The discharge was stopped at approximately at 11:00 am.",
