Pretreatment Annual Report January 1, 2023 - December 31, 2023 Pretreatment Program covers: Long Creek WWTP - NCO020184 Crowders Creek WWTP - NCO074268 1. GENERAL INFORMATION A. General Program Information: • Pretreatment approvals and updates: o Sewer Use Ordinance (SUO): SUO effective and approved 12/27/2012. o Enforcement Response Plan (ERP): Effective and approved 2/5/2020. o Industrial Waste Survey (IWS): The 5-year IWS report was last received by DEQ on 6/26/2020 and approved 9/17/2020. The IWS will be appropriately maintained and TRU is transitioning all the data to the updated spreadsheet obtained on the DEQ website. o NPDES Permits: Long Creek WWTP NPDES permit became effective 2/1/2022 with the expiration date of 1/31/2027. The Crowders Creek WWTP NPDES permit became effective 9/1/2021 with the expiration date of 8/31/2026. o Long Term Monitoring Plan (LTMP): The Long Creek WWTP LTMP was approved on 9/6/2019. No updates were necessary due to the renewal of the Long Creek NPDES permit. The Crowders Creek WWTP LTMP was last approved on 8/25/2017. An updated LTMP with minor changes was received by DEQ on 1/12/2022 due to the Crowders Creek NPDES renewal and is pending DEQ approval. o Headworks Analysis (HWA): The Long Creek WWTP HWA was last approved 8/28/2017. Updates were received by DEQ on 8/28/2020 and are awaiting DEQ approval. The Crowders Creek WWTP HWA was last approved on 4/15/2020. Updates submitted on 1/12/2022 due to the Crowders Creek WWTP NPDES renewal and are awaiting DEQ approval. o Allocation Table (AT): As of 12/31/2023, the Long Creek WWTP AT had last been updated 8/1/2022 due to the modification of Selkirk Reality (Permit #1071). In 2024, the Long Creek AT was updated on 2/1/2024 for two new SIUs, which was submitted to DEQ on 12/1/2023. The most recent Long Creek AT is included in this PAR. Crowders Creek WWTP AT was updated on 10/1/2023 for a permit modification for IFAB (Permit #1062), which was submitted to DEQ on 8/8/2023. Page 1 of 5 1 o Dental Amalgam: Two Rivers Utilities (TRU) has identified 39 active dental facilities in the service area. TRU received, reviewed and retained 38 one-time compliance (OTC) forms by the end of 2023. A new Dental facility began operations at the end of 2023, and we are working with the customer to get a OTC form. As new dental facilities open, OTC forms will be requested for completion from these facilities. TRU does not have any current concerns with mercury at its WWTPs, but will continue efforts to implement the Mercury Minimization Plan. • Pretreatment Program Info Database (PPID) — Updates attached. o Comments for Crowders Creek WWTP PPID: ■ Program SIUs are 23 and CIUs are 7 as of the date of this report. ■ Current Fiscal Year PCI done on 8/22/2023. ■ The HWA and LTMP comments are similar to the narrative above. ■ Contacts are the same. o Comments for the Long Creek WWTP PPID: ■ Program SIUs are 23 and CIUs are 7 as of the date of this report. ■ WWTP SIUs are 15 and CIUs are 3 as of the date of this report. ■ Current Fiscal Year PCI done on 8/22/2023. ■ The "% design mgd is SIU permitted" is 21.93 because the "Permitted SIU flow" is 3.508 mgd. ■ The HWA and LTMP comments are similar to the narrative above. ■ Contacts are the same. • Historical SNC Report is not attached because DEQ is updating tracking program. B. General Permit Information • Crowders Creek WWTP SIU Permits o No Crowders Creek WWTP SIU permits lapsed or expired prior to renewal. o Permit modification for permit #1062 (IFAB) approved by DEQ on 9/15/23 and became effective 10/1/2023. • Long Creek WWTP SIU Permits o No Long Creek WWTP SIU or IU permits lapsed or expired prior to renewal. o No Permit modifications or renewals occurred in 2023. o SIU Permit #1013 (Sunshine Uniform) was rescinded on 12/15/2023 due to the close of business on 11/30/2023. o SIU Permit #1072 (Champion Powder Coating) was rescinded on 10/31/2023 due to ceasing process wastewater discharge to sewer. Local IU #2019 issued to user to monitor operations. o In 2024, there have been two new SIU permits issued. SIU Permit #1074 (Hans Kissle Company LLC) effective 1/1/2024 and SIU Permit #1073 (GNT USA, LLC) effective 2/1/2024. Page 2 of 5 2. INDUSTRIAL USER INFORMATION A. 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: 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.
