DANIEL SMITH Director Mr. Scott Cranston, Plant Manager Louisiana-Pacific Corporation Post Office Box 98 Roaring River, North Carolina 28669 NORTH CAROLINA Environmental Quality March 30, 2021 Subject: Review of the 2020 Annual Report LP Roaring River Mill, Distribution/Land Application of Class A Residuals Permit No. WQ0000461 Wilkes County Dear Mr. Cranston: Staff of the North Carolina Division of Water Resources Winston-Salem Regional Office (DWR) has completed a review of the 2020 Annual Report for the subject facility. This review was completed by DWR staff person Patrick Mitchell. The majority of the review reflects compliance with Permit No. WQ0000461. However, the following deficiency warrants your continued attention and action: The groundwater sampling results for three of the monitoring wells (i.e., MW-1, MW-5, and MW-9) serving the former dedicated land application fields continue to show Nitrate concentrations greater than the NC Groundwater Standard limit of 10.0 mg/L. Please be reminded that Permit Condition I.1. requires that an investigation shall be conducted and a report containing a corrective action plan shall be submitted to the Division within 180 days of permit issuance (i.e., on or before May 17, 2021). If you have any questions regarding this letter, please contact Patrick Mitchell or me at the letterhead phone number or address, or by email at patrick.mitchell@ncdenr.gov or lon.snider@ncdenr.gov Sincerely, �DocuSigned by: < L-0ti 1.

No site visit was made as part of this inspection event. The majority of the report reflects compliance with the subject permit. However, groundwater sampling results for the former dedicated fields shows exceedances for Nitrate in three of the monitoring wells. Below is a summary of notes from this review. • Monitoring wells MW-1, MW-5, and MW-9 all exceeded the groundwater limit of 10 mg/L for Nitrate. • Copper and Zinc were reported as elevated (i.e., >2,000 index value) for site sample "WHRLP". It should be noted that no land application was reported as occurring after March 31, 2020 and the new permit is for inactive (i.e., 0 residuals production or distribution). Therefore, no land application should be occurring from the subject facility. If this site is returned to use, soil sampling should be completed to ensure Copper and Zinc levels are not too high. • Residuals analyses results provided in the 2020 report met regulatory limits. • Field loading records suggests that all land application that occurred in 2020 was conducted within agronomic loading limits.
