Director Mr. Benjamin P. White, General Manager WestRock Kraft Paper 100 Gaston Road Roanoke Rapids, NC 27870 Dear Mr. White: NORTH CAROLINA Environmental Quality September 14, 2023 Subject: NC0000752 WestRock/Kraft Paper 001 and 002 Investigative Monitoring Roanoke Rapids Mill WWTP Halifax County (RRO) Facility Class IV Recent concerns about elevated water temperatures in the Roanoke River have been brought to the attention of the Division of Water Resources (DWR). Follow-up by DWR staff, along with communications with facility personnel, indicates the WestRock facility is likely the source of the elevated instream water temperatures. WestRock's January 20, 2023, permit renewal included temperature requirements that addressed instream temperature monitoring. For specific details, refer to the permit at page 3 Condition A. (1) in the table related to "Temperature" and at footnote number 8; and at page 4 Condition A. (2) in the table related to "Temperature" and at footnote number 1. Based on the above, DWR is requesting expedited investigative monitoring and completion of the temperature modeling study as described below. The authority for such additional investigative actions can be found in 15A NCAC 02B .0508 (b)(2) and G.S. 143-215.66. REQUIRED ACTIONS Based upon the forgoing issue and regulatory authority, beginning within thirty (30) days of the date of this letter, the Permittee shall implement the following additional investigative requirements: 1. Investigative Monitoring Map: Prior to implementation, the Permittee shall submit a map to DWR for review and possible approval. The map shall include at a minimum the following: (1) Aerial/Site location map; (2) Facility location; (3) Location of outfall(s) (latitude and longitude); (4) Sampling and monitoring location(s) (latitude and longitude); (5) Map scale (e.g. 1" = 500' or USGS Map); (6) Distance in feet from outfall(s) (latitude and longitude) to sampling location(s); (7) Upstream and downstream monitoring locations (latitude and longitude); (8) Waterbody name; and (9) Major roads. Once approved, Permittee shall implement the monitoring, sampling and reporting below.

Effluent shall be sampled for temperature prior to discharge, three (3) times per week for each Outfall (i.e., 001 and 002). b. Instream water temperature sampling shall occur upstream of the discharge points and shall be sampled three (3) times per week. The sampling locations shall be approximately 1,000 feet above the facility discharge points. c. Instream water temperature sampling shall occur downstream from the discharges and shall be sampled within 100 feet and within 1,000 feet of the discharge points three (3) times per week. 2. The Permittee shall submit Discharge Monitoring Reports electronically using NC DWR's eDMR application system per Special Condition A. (6) (G.S. 143-215.1(b)) of the Permit. In addition to reporting the monthly results on the facility's eDMR, send a copy of all results to the DWR NPDES Industrial Permitting Unit within thirty (30) days of the end of each calendar month to: sergei.chemikovgdeq.nc.gov. Please include your NPDES permit number and reporting period in the subject heading. 3. The facility shall provide a schedule for conducting and completing the temperature modeling study as specified in the NPDES permit at page 3 footnote number 8. The sampling and reporting protocols specified herein shall remain in effect until rescinded by DWR in letter form. If necessary, NPDES staff will contact you to develop additional corrective actions based upon the results of the data.
