Outage is scheduled to continue thru 3/25/18 Revision 3, 10/1/08 Blue Ridge Paper Products Inc. dba Evergreen Packaging Have efforts been made to mitigate the occurrence? Lower end is trying to ease back on dumping and be mindful of flow and color going into the sewer in their areas. Is corrective action recommended? Yes Corrective Action Implemented: Lower end was instructed to cease dumping and control all flow and color going into the sewers in their areas. *Describe incident in detail including regulated substance (black liquor, turpentine, or soap) that went to the Wastewater Treatment plant: A combination of outage related washing, black liquor, fiber, and lime mud were dumped into the sewer throughout the day causing very high flow and color in the influent stream to the WTP. Describe any other necessary information: WTP operators began adding our color reducing polymer Amerfloc 485 very early on 3/20 at the low lift, in the primary system and the secondary system. The decision was made in the afternoon after still seeing a rise in influent color that the concentration of CRP needed to be adjusted. A higher concentration of CRP was added into the process and we began to see the effects within a few hours. The CRP was reducing the color numbers significantly, so we continued with the higher dosage until lam on 3/21. At IOpm on 3/20 influent flow was directed into the #1 clarifier to reduce flow just in case. Secondary effluent color came in at 83,651 for the day, 20k below the limit. More polymer was brought in by the vendor on 3/21, shipments are scheduled for 3/22 as well. High color continued into 3/21. The lower end supervisors were notified of every color over 300ppm. The outage continued to impact color throughout the day. CRP was added throughout the day.

Non-BMP incident ❑ Test Method Interference ❑ New Method = Turbidity = Secondary Effluent (with one day lag time) _ Outage x Other ❑ Is problem ongoing? No, weak wash is no longer over flowing. �. Have efforts been made to mitii4ate the occurrence? Weak wash tank was overflowing sending very high pH material to the WTP, tank level was pulled down. Revision 3, 10/1/08 Blue Ridge Paper Products Inc. dba Evergreen Packaging I Is corrective action recommended? Lowering tank level was the corrective action in this case. Corrective Action Implemented: Yes *Describe incident in detail including regulated substance (black liquor, turpentine, or soap) that went to the Wastewater Treatment plant: Ou'zage work hias delayed the startup of many of the j,,;roccsses in the rower end, weak wash wlatgch is used to flute nine green liquor hn thie sr±ich dissolving ta±ilks isn't being pulled down fast enough so the weak wash tank is over .lowing.
