One of the facility's ponds (Tank Farm Pond) overflowed onto a bermed road. The water overtopped the berm and flowed down the adjacent hillside to Alameda Creek. Part of the berm was sloughed off and carried with the water towards the creek. Water also reached an area called "Creek Crossing" where Calaveras and Alameda Creek intersect. The quantity of water that was discharged is unknown. MVR suspects that the discharge was caused by non-synchronized pumps. Estimated quantity of discharge: 10,007 gallons. |
MVR staff put out sandbags and reinforced the berm. Facility backfilled top of sloughed area. The road will be closed and the berm will be raised over the summer. An evaluation of the removal of sloughed berm material from the slope will be conducted. Facility management is implementing a daily log to track operation of the Tank Farm Pond pumps to ensure they remain in sync and water level is controlled. |

The leaking valve is in the process of being repaired. Until the leaking valve is repaired, water from the Pit 1 Pond is being pumped concurrently with water from the West Nursery Pond to ensure that the Supply Tank is fed from both ponds as usual." |
