NORTH CAROLINA Director Environmental Quality 8/5/2024 Via Electronic Mail(bpatterson@burlin onnc.gov) Robert C. Patterson,Jr.,P.E. Water Resources Director City of Burlington P.O. Box 1358 Burlington,NC 27216 Subject: Pretreatment Compliance Audit Program: City of Burlington Wastewater Treatment Plant: East WWTP and South NPDES #: NCO023868 and NCO023867,Alamance County Dear Robert Patterson: On July 17,2024 a Pretreatment Compliance Audit(PCA)was performed by Octavio Henriquez, Stephanie Zorio,and Natalie Gorensek of the Central Office. Kristy King Hylton of the City of Burlington was present for the audit. The purpose of this audit was to determine the effectiveness of the City's pretreatment program,which includes the review of files,including industrial monitoring data, POTW plant performance, industry monitoring data, adherence to the enforcement response plan(ERP),an industry inspection, and other pretreatment elements as outlined by 15A NCAC 02H .0900. Background The city has thirteen(13) Significant Industrial Users(SIUs),three(3)of which are categorical under federal regulations. The City of Burlington's Publicly Owned Treatment Works(POTW)operates two Wastewater Treatment Plants(WWTP).Both Burlington East(NC0023868)and Burling South(NC0023786)WWTP are permitted for 12 MGD. POTW Interview There are no known POTW issues related to pretreatment at the time of this PCA. Pretreatment Program Elements Review The Headworks Analysis(HWA)renewal was submitted on March 17, 2020. The HWA renewal is currently awaiting review by the Division. The Industrial Waste Survey(IWS)was approved on August 10, 2022. The Sewer Use Ordinance(SUO)was approved on March 1,2013. The Enforcement Response Plan(ERP)was approved on February 5,2020. The Long Term Monitoring Plan(LTMP)was approved on January 27,2006. D E Q�� North Carolina Department of Environmental Quality I Division of Water Resources 512 North Salisbury Street 1 1611 Mail Service Center I Raleigh,North Carolina 27699-1611 NORTH CAROLINA 919.707.9000 Uapad—t of E,,kon—tal Quay Docusign Envelope ID:3FC83COE-394F-431C-9EE6-ED835128AE77 LTMP File Review Findings The Division reviewed the LTMP from 2006 and found the PQLs to be out of date.A new PQL list was released in 2022. We request that the City of Burlington revises the LTMP with the updated PQLs. The Division requests that the City of Burlington proposes an appropriate timeline for implementation. The Long Term Monitoring Plan(LTMP)is being conducted at the proper locations and frequencies. Industrial User Permit(IUP)File Review None of the thirteen(13) SIUs were in significant noncompliance(SNC) in 2023. A review of the file for ITG Burlington Industries dba Elevate Textiles (#0006)revealed that the monitoring data was well-organized and in compliance with pretreatment rules. A review of the file for Alamance Foods (#0067)revealed that the monitoring data was well-organized and in compliance with pretreatment rules. A review of the file for Engineering Controls International, LLC(#0019)revealed that the monitoring data was well-organized and in compliance with pretreatment rules. The slug control plan for ITG Burlington Industries dba Elevate Textiles(#0006)was in good order. The slug control plan for Alamance Foods (#0067)was in good order. The slug control plan for Engineering Controls International, LLC(#0019)was in good order. Industry Inspection The team from the Division and Kristy King Hylton visited ITG Burlington Industries dba Elevate Textiles for an annual inspection. The inspection revealed that Kristy King Hylton used the Division Model Inspection Form or Equivalent and performed a thorough inspection including: Initial Interview,Plant Tour, Sampling Review, and an Exit Interview. The plant tour revealed an area of chemical storage that could benefit from additional spill containment(such as spill containment pallets)and this was noted during the inspection and the City of Burlington will take action. Action Items Obtain official IUP review letter from the Division for Alamance Foods(#0067)and Engineering Controls International, LLC (#0019). The Division reviewed the LTMP from 2006 and found the PQLs to be out of date.A new PQL list was released in 2022. We request that the City of Burlington revises the LTMP with the updated PQLs. The Division requests that the City of Burlington proposes an appropriate timeline for implementation. Final Comments The Division set a tentative due date for the next Headworks Analysis of March 2025. The HWA submission from 2020 is still under review and in effect.

The facility currently uses PFAS in their production,but they have a compliance schedule to eliminate usage by January 2025.The facility plans to cease using PFAS by the end of this month. Small spill observed under some pallets and plastic was being used as containment. Suggested that they invest in some containment pallets to help with this. Audit SUMMARY AND COMMENTS: Audit Comments: The Pretreatment program files were well organized and accessible to the inspector. Kristy was highly competent and accommodating and has a vast knowledge of the requirements of the PT program for each of the POTW's industries. The Division notes that official review letters for IUPs for Engineering Controls and Alamance Foods were missing, and that the Inspectors will work with other members of the Division and Kristy to resolve this issue.
