A diligent effort is underway by Operations and Process personnel to identify and correct the source of this and previous TOC excursions Insufficient bleach addition and other operational parameters are beinq examined closely for some type of correlation with'hiqh TOC levels. 1 Due to a reduced demand for product; idled chlorine circuits have caused an increased flow to the Lead OVO' In to Treatment ponds, thereby reducinq the retention time ` allowed for sedimentation of suspended solids. Subsequent to this sample, the flow has been decreased by brinqinq another chlorine circuit on stream. r, p -: -N'-v i 1 -- .
