The plant was experiencing high turbidity and the plant was put on diversion for most of the day. The pH and temperature were not measured during the approximate 40-minute window when the laboratory analyst was present due to a misunderstanding. The laboratory analyst thought that the plant was going to be discharging the rest of the day but the turbidity was high that the plant operator on site had to put the plant on diversion into the following morning. |
