The secondary effluent color samples taken on 1/10/14 and 1/11/14 were shown to have exceeded the permitted daily maximum value of 1 105,250 lbs/day.Proper sampling procedures were followed by plant personnel. The result of the analyses showed a value of 125,731 lbs/day for 1/10 and 129,856 lbs/day for 1/11. All other effluent parameters were within permit requirements. A phone call was placed to the NCD WR j regional office to relay information about the current conditions at the mill. On Tuesday 1/7,the Canton area experienced subzero temperatures (-6°F). As a result of the extraordinary low temperatures,a level cell in the Deaerator Tank froze at approximately 6:30 a.m., sending a false"high level" signal to the DCS system. As a result of the false signal, each boiler ran out of feed water causing the boilers to trip off. Additionally,the mill experienced a loss of power and a cold mill shutdown. i During the process of restarting the mill, elevated color material was sent to the sewer and i captured in the mill's extensive sump system for subsequent processing. This continued until all available spill tanks were full. The continued freezing temperatures made it difficult to get the mill back to steady operations. Lines typically used to transfer spill materials were frozen and ffeshbydesignY \\ewrpack\CFMShare"0HS\Sh9re\Water FilaNick's Water Files\DWR NCDWR Page 2 J inoperable. Moreover, Evergreen personnel were diligent in their efforts to minimize color and are confident that no environmental impact resulted from the excess color. Additional mitigating measures included utilizing the W WTP spare clarifier to capture material that could not be processed within the mill, and using polyamine to help with the elevated color. The conditions causing the cold mill shutdown and release of color in excess of the daily maximum limit on 1/10 and 1/I1 were beyond the control of the Canton Mill. If you have any questions or comments,please feel free to contact us at your earliest convenience.
