Closure plan for the X-230J7 Holding Pond

Technical Report · Wed Jul 01 04:00:00 EDT 1992

OSTI ID:6985318

The X-230J7 Holding Pond is identified as NPDES outfall 001. The pond was constructed to control sediments in stormwater runoff from storm sewers D and E and the east drainage ditch which drain the mid-northeastern area of the plant site. The pond also accepts once-through cooling water (water that passes once through the plant air conditioning system and is discharged to the storm sewer system). Until November 1988, the east drainage ditch received effluent from the X-701B holding pond (NPDES 601). The concentration of trichloroethylene entering X-230J7 from X-701B was monitored and averaged 400--600 ppb (parts per billion). Potential contaminants include caustic soda, nitric acid, uranium, sodium bifluoride, oil, PCBs, diesel fuel, sulfuric acid, and volatile organic compounds (VOCs). This report describes the closing of this pond.
