SIGNIFICANT NON-COMPLIANCE / PENALTIES • There were no SIUs or IUs in SNC during 2023. • Altus Finishing (IU Permit #2016) was issued an NOV for the July-December 2023 period for not sampling as required in the IU permit. Altus had been required to notify TRU of the next batch discharge and originally stated there were not any discharges at the end of 2023. An email from user on 1/4/2023 stated they miscommunicated during the previous period, and there were batch discharges occurring that contained process water. Due to the missed sampling, Altus Finishing was assessed a $600 civil penalty, and it was paid promptly in March 2023. B. ORDERS AND SCHEDULE INFORMATION • The Champion Powder Coating Consent Order was completed on 6/30/2023. Consent Order was provided to DEQ in the 2022 PAR. The user stopped discharging process wastewater to sewer, so SIU permit was rescinded and a local IU permit #2019 was effective immediately on 11/1/2023 to continue to monitor Champion Powder Coating. C. AUTHORIZATIONS TO CONSTRUCT (AtoC) • None D. MISSING IDSF DATA • Champion Powder Coating (Previously SIU Permit # 1072, and now IU #2019) stopped process discharge in February 2022. The 2023 sampling was not applicable since no discharge occurred. • Darling Ingredients (SIU Permit # 1047) did not discharge and therefore no sample was collected for the entire 2023 period. • MANN+HUMMEL (SIU Permit # 1067) did not obtain a 24-hour flow reading for the January sample due to a broken effluent wastewater meter that was waiting on parts for repair. The 12-month average daily flow was used for compliance evaluation during the January 2023 sampling event. E. OTHER IDSF DATA COMMENTS • All TTO and OCPSF Pollutants TTO Certifications are input as "Certified" except when TTO sampling was performed. • Priority Pollutant results Wind River Environmental (IUP #1066) and GC Landfill (IUP #1051) both sample annually for a modified Priority Pollutant list similar to 40 CFR part 423. No pollutants in either sample were concerning. • Flow Limit compliance judgment Daily flow limits are all evaluated on 24-hr flow reading during TRU sampling events. Monthly flow limits are evaluated from monthly meter readings. Page 3 of 5 3 3. OTHER INFORMATION A. SIU INSPECTIONS Inspections of all permitted industrial users were completed during 2023.

INDUSTRIAL WASTE SURVEY The five-year IWS Report was received by DEQ on June 26, 2020. Pretreatment staff receives monthly notifications of building permits issued and planning/zoning changes that relate to industrial areas. In 2023, new industrial customers were evaluated using the following criteria: City of Gastonia billing database, North Carolina Manufacturers Register, economic development reports and status updates, phone calls, site visits, IWS form or wastewater permit applications. The IWS list will continue to be updated when new findings are made. The following IUs were being evaluated during 2023: Hans Kissle LLC IWS & permit app received 11/7/2022 SIU Permit issued in 2024. GNT, USA Full permit app received 5/26/2023 SIU Permit issued in 2024. Piedmont Lithium Potential future discharge is being evaluated C. OTHER MUNICIPALITIES Town of Cramerton and City of Belmont The Town of Cramerton transferred the sewer system, including the Eagle Road WWTP, to TRU in 2011 by an inter-jurisdictional agreement (IJA). A portion of the City of Belmont's wastewater is treated at the Eagle Road WWTP. An IJA is in place with the City of Belmont. No SIUs are located in Town of Cramerton or the portion of Belmont that discharges to the Eagle Road WWTP, therefore a pretreatment program is not required for the Eagle Road WWTP. Towns of Dallas, McAdenville, Ranlo and High Shoals; City of Lowell A portion of the wastewater from Lowell and Dallas, and all the wastewater from the other municipalities is treated at the Long Creek WWTP. TRU has IJAs with these municipalities. These municipalities do not have any SIUs at this time and therefore do not require a pretreatment program. The Town of Ranlo has an inactive pretreatment program. Town of Stanley All wastewater from the Town of Stanley's collection system is treated at the Long Creek WWTP. TRU has an IJA and SIU Permit #1069 with the Town of Stanley. TRU also has a contract agreement for operations of the town's pretreatment program. A separate PAR is submitted by TRU for the Town of Stanley (Program # WQCS00180). Two SIUs discharge to the town's collection system. Town of Clover, City of Bessemer City and City of Kings Mountain Wastewater from Clover, Bessemer City and a portion of Kings Mountain is treated at the Crowders Creek WWTP. The Cities of Bessemer City and Kings Mountain operate pretreatment programs regulated by NC DEQ. The Town of Clover operates a pretreatment program regulated by South Carolina DHEC. IJAs are in place with each municipality and SIU permits have been issued to each by TRU.

The submission was received by the Division on 10/09/2023. SIU# SIU NAME 1072 Champion Powder Coating, Inc. The review indicates the IUP has been dropped by the Two Rivers Utilities Pretreatment Program and the documentation meets the minimum requirements of 15A NCAC 2H .0916 and 40 CFR 403.8(f)(1)(iii). The allocation table,maintained in the Division's database,has been updated accordingly. Within 180 days of the effective date of any reissued or modified NPDES permit the permittee would be required to submit to the Division a written technical evaluation of the need to revise local limits (i.e., an updated IWS, or documentation of why one is not needed). This action may include revising, updating, or adding to the list of Significant Industrial Users (SIUs). Pursuant to 15A NCAC 2H .0907(b) either the Division or the permittee may initiate pretreatment program revisions. Federal and State pretreatment regulations require the local delegated pretreatment program to effectively control and document the discharge of wastewater from Significant/Categorical Industrial Users to the POTW. It is the POTW's responsibility to ensure that these objectives are consistently met. Thank you for your continued cooperation with the Pretreatment Program.
