Dear Permittee: The Division of Water Resources (Division) acknowledges that the volume and characteristic of wastewater discharged per the subject NPDES permit will transition in the coming months as the facility initiates a phased shutdown. The Division is of the understanding that the subject wastewater treatment plant (WWTP) will continue treating all the Town of Canton's municipal wastewater for at least a two (2) year period beginning March 8, 2023. The purpose of this notice is to make you aware of compliance responsibilities during the transition.As the permittee,you remain responsible for compliance with your NPDES permit. The NPDES permit may be transferred to a new owner of the WWTP for continued operation or may be rescinded/revoked after proper WWTP closure. In either case, a Division permitting action is necessary. The Division is in receipt of the wastewater treatment system transition plan received on March 17, 2023,that cites three phases of transition. Based on the expected significant changes in operation of the facility, the Division is requiring notification to be made to the Division at least five (5) calendar days prior to the implementation of each transition phase or sub-phase. Notification(s) shall describe any deviation from the submitted transition plan and list those treatment units that will be modified or taken offline. Notification(s) may be made via email to regional staff at Landon.Davidson(@ncdenr.gov and to the central office at Sergei.Chernikovpncdenr.gov. The Division understands that the facility is currently in transition Phase 1A. Please refer to your permit for additional reporting requirements.

The permittee of NC0000272 is to submit a revised permit application at least thirty (30) calendar days in advance of the implementation of Phase III of the transition plan. Permit condition A.6. Section B.4. states that the Best Management Plan (BMP) must be amended whenever there is a change in mill design, construction, operation or maintenance that materially affects the potential for leaks or spills of spent pulping, liquor, turpentine or soap from immediate process areas. Pursuant to the section,the DWR interprets proposed shutdown phasing as having potential to materially affect the potential for impacts. Therefore,the Division is requiring the submittal of an amended BMP Plan that specifically addresses any modifications, enhancements, etc. necessary to ensure leaks and spills are managed closely during all phases of the shutdown beginning with Phase 1B. The amended BMP should evaluate the need for enhanced WWTP influent monitoring to ensure protection of the plant and receiving waters. An amended BMP Plan or a written response to this requirement is to be submitted to the regional office at least ten (10) calendar days prior to implementation of Phase 1B. Prior to any facility system treatment unit(s) final closure, the Division will require an approved facility closure plan. The plan will need to specify treatment unit(s) closure processes, ensuring all contents of any affected unit(s) are removed and disposed of properly.All system(s) and unit(s) taken off-line must be closed out per Division Policies as reflected in Attachment 1 herein. Please note that compliance with all permit conditions is required including monitoring until such time as written approval is obtained from the Division or a modified permit is issued. The Division appreciates your continued cooperation in this matter. If you should have any questions please contact Sergei Chernikov Ph.D., Environmental Engineer III at: 919- 707-3606 or via email at: Sergei.ChernikovOncdenr.gov.

Dee Freeman Governor Director Secretary June 22,2012 MEMORANDUM TO: Aquifer Protection Section Staff Interested Parties FROM: Ted L.Bush,Jr.,Deputy Direct Division of Water Quality SUBJECT: Guidelines for the Closure o mitted Wastewater Ponds and Lagoons Purpose The purpose of these guidelines is to provide a course of action for the closure of permitted Non-Discharge wastewater treatment ponds,storage ponds,or lagoons. According to G.S. 143-215.1,construction and operation of any sewer system,treatment works or disposal system within the state of North Carolina requires a permit. 15A NCAC 2T.01050)requires that waste treatment systems(or parts thereof,such as lagoons,storage ponds,etc.) authorized by a permit must be properly closed before that permit(or parts thereof)can become inactive. These guidelines provide clarification as to what"properly closed"entails. While each structure must be considered for its unique circumstances,the Aquifer Protection Section(APS)has outlined general procedures(attached)to be used for closure of wastewater treatment ponds and lagoons permitted by the Section. These guidelines are not intended to address lagoons used for animal waste and their associated facilities,or ponds used for the storage of coal combustion by-products. However,it is the intent of APS to require similar close out procedures for comparable scenarios in coordination with other permitting agencies such as the Surface Water Protection,or other interested parties. These guidelines supersede Guidelines for the Closure of Treatment Ponds and Lagoons implemented August 18,2003. Closure Approval The closure of a Non-Discharge permitted wastewater treatment or storage pond or lagoon should begin with notification by the permittee to the APS. This should include a request to close a specific permitted pond or lagoon, and an indication whether the permit should be modified or rescinded. APS will make available the attached closure checklist/guidelines to the permittee,who should propose a closure plan based on the attached guidelines. This closure plan should generally include or describe the following(see next page): i i I 1617 Mail Service Center,Raleigh.North Carolina 27699.1617 Location:512 N.Salisbury St.Raleigh,North Carolina 27604 Phone:919-801-6300 1 FAX:919-807-6492 Internet:wwwrimaterguality.org 7�7One ,..f�t, An Equal Opportunity 1 Affirmative Action Employer L V�,L1��aI•�hna ;Vaturallty D � � North Carolina Department of Environmental Quality 1 Division of Water Resources Asheville Regional Office 12090 U.S.Highway 70 1 Swannanoa,North Carolina 28778 NORTH CAROLINP, 0spe"emm Emimamamai auaury 828.296.4500 DocuSign Envelope ID: B700D5E5-4B4C-409C-8E9D-F7F9A2FB8081 Guidelines for the Closure of Permitted Wastewater Treatment Storage Ponds and Lagoons • Checklist with chosen options and requirements indicated(Attachment A,page A-1) • Historical use of impoundment(include all waste streams)and current status • Future plan for site • Disposal options for wastewater • Disposal options for sludge • Sludge disposal location(s) • Sampling plan for wastewater and/or sludge Once the permittee submits their closure plan,a preliminary inspection will be conducted and an inspection report with additional closure instructions(if needed)will be presented to the permittee.

The final closure report may include the following: • Sampling results • Volume of sludge disposed and location • Companies/Contractors involved • Final Certifications The Regional Office will conduct a final inspection and present the results of that inspection to the permittee,along with their recommendation to the APS Central Office for approval or disapproval of a permit modification or rescission. Applicable Regulations Regulations that may be applicable to the abandonment of Non-Discharge permitted ponds and lagoons are listed below. These guidelines do not go into the detailed requirements of the regulation listed. However,each bullet summarizes how the regulation may be applicable to the action requested. • Title 15A NCAC 2L,Classifications and Water Quality Standards Applicable To The Groundwaters of North Carolina. This regulation requires that groundwaters must be protected to a level of quality at least as high as that required under standards established in Section.0202 of that Rule. • Title I SA NCAC 2T, Waste Not Discharged to Surface Waters. This rule establishes requirements that are protective of surface water and groundwater standards for systems that treat,store,transport,and dispose of residuals and do not discharge waste to surface waters. Other pertinent standards and regulations may be found in the Department of Environmental and Natural Resources (DENR)Division of Land Resources(DLR)regulations pertaining to Sedimentation and Erosion Control and Dam Safety,the DENR Division of Waste Management(DWM)regulations pertaining to the disposal of wastes and sludge,and the Department of Transportation(DOT)regulations pertaining to transportation of materials on public highways. cc: Surface Water Protection(Matt Matthews) Attachments A, Checklist and Instruction Items B.

Wastewater Sampling.Analysis, and Disposal 1. ,Pond samples require a composite sampling technique. Samples should be composited from several locations. An adequate number of representative and composite samples should be taken and developed respectively. 2. For permitted disposal sites,sample and analyze wastewater in accordance with permit conditions. In the absence of permit specified monitoring,sample for the following parameters: a. Fecal coliform bacteria,chlorine residuals(if used as disinfectant),total nitrogen,BOD5,TSS,pH- b. Other parameters may be required based on waste streams,as directed by the APS Regional Supervisor. 3. All wastewater samples must be analyzed by a DWQ-certified laboratory. 4. Once the wastewater is sampled,the pond/lagoon can be dewatered to a permitted disposal site(uniform application of wastewater)or through a pump and haul permit. 5. Remove or plug all inflow and outflow piping,etc to the pond/iagoon Item B. Conversion to Non-Wastewater Pond(Tertiary Treatment Ponds Only) 6. Determine pond liquid volume(if water accumulates after complete disposal per Item A,Wastewater Sampling,Analysis, and Disposal). 7. If some sludge remains,sludge can be left in place,in accordance with Item E#23 below. Otherwise, remove all residuals and dispose of properly per Item D,Sludge and Soil Disposal. 8. Disinfect and/or treat pond to meet Item B#1 I requirements below. 9. Sample pond(see Item A,Wastewater Sampling,Analysis, and Disposal) 10. No pond discharge is allowed to surface water without prior approval from an appropriate Surface Water Section Regional Office.Note that pond discharge to class SA waters is not allowable. 11. All discharges must meet water quality standards applicable to receiving stream classification or per limits provided by DWQ when water quality stream standards for monitored parameters are not defined. Item C. Soil and Sludge Analysis 12. All soil and sludge samples require a composite sampling technique. An adequate number of representative and composite samples should be taken and developed respectively. Thickness of sludge or soil and surface acreage should be considered. Example:one composite sample per acre foot. 13. All soil and sludge samples must be analyzed by a DWQ-certified laboratory. 14. For biological wastewater lagoons systems and tertiary wastewater pond systems,soil or sludge shall be sampled for: a. Pathogen and Vector Attraction Reductions.Testing should be done per 15A NCAC 02T.1100. If project concerns only a tertiary pond,and pond sediments/sludge meets Class A pathogen reduction requirements(maximum of 1000 fecal coliform bacteria colonies per gram of total solids),additional characterization for pH,metals,nutrients,and solids as stated in 14.b and 14.c (below)may not be required,as determined on a case by case basis. b. Arsenic,cadmium,chromium,copper,lead,mercury,molybdenum,nickel,selenium,zinc,TKN, ammonia nitrogen,nitrate/nitrite,nitrogen,phosphorus, sodium,calcium,magnesium(mg/kg dry wt basis),percent total solids and pH. c. Other parameters may be required based on waste streams,as directed by the APS Regional Supervisor.

For industrial wastewater lagoon systems,this should be the same as biological wastewater lagoon system sampling plus site-specific parameters and hazardous characterization to include,but not limited to,TCLP, ignitability,corrosivity and reactivity. 16. If the sludge or soil samples are: a. Required to be analyzed for hazardous characteristics and results exceed hazardous characteristics regulatory limits,the material needs to be removed and reported to and managed in accordance with the Hazardous Waste Section in the Division of Waste Management. b. Not required to be analyzed for hazardous characteristics or results do not exceed the hazardous characteristics regulatory limits,the soil can be left in place if the following conditions are met i. Total concentrations of contaminants in soil do not exceed protection of groundwater soil concentrations for North Carolina based on 2L standards,as calculated using theTransport Model for Calculation of Soil-to-Groundwater Concentrations from the USEPA 1996 Soil Screening Guidance document. (The EPA Transport model can be found in the"Soil Remediation Goals Table"at hgp:Hportal.ncdenr.orp-,/web/wm/sf/ihs/ihs ug ide or the"2L, MCL,and Soil Screening Levels Table"at http•//portal.ncdenr.org/web/wm/hw/technical/guidance.) ii. Total concentrations of contaminants in the soil exceed protection of groundwater soil concentrations for North Carolina,but results do not exceed naturally-occurring background concentrations, iii. A more stringent soil clean-up level is not necessary due to site specific conditions as determined by the Division. For sludge left in place,see Item E,Sludge Left in PIace, For sludge disposal,see Item D,Sludge and Soil Disposal. c. Not required to be analyzed for hazardous characteristics or results do not exceed hazardous characteristics regulatory limits,but total concentration results exceed corresponding protection of groundwater soil concentrations for North Carolina as calculated using the Transport Model from the USEPA 1996 Soil Screening Guidance document described in 16(b)(i),soil and sludge must be disposed of according to Item D,Sludge and Soil Disposal. For soils that exceed protection of groundwater levels,Item G,Groundwater Post Closure Monitoring,must also be considered. 17. For ponds or lagoon bottoms that intercept groundwater,Regional Offices will determine what type of sampling is required for the remaining contents on a case by case basis. Item D. Sludge and Soil Disposal 18. Measure surface area and depth of sludge and soil(if required)to determine disposal volume 19. Sample sludge and soil(if required)for permitted disposal option including pathogen and vector attraction reduction verification(see Item C,Soil and Sludge Analysis) 20. If a tertiary pond and sludge/sediments meet Class A pathogen and vector attraction reduction requirements,sludge/sediments can be land applied uniformly on site without sludge permitting action (additional sludge or soil characterization may not be required,as determined on a case by case basis). 21. If sludge or soil does not meet Class A pathogen and vector attraction reduction requirements, sludge/sediments may require a permit modification to land apply. 22. Pathogen and vector attraction reduction testing will not be required if sludge or soil is taken to a permitted compost or another treatment facility for further stabilization.

Slud a Left in Place 23. For closure purposes,the Division of Water Quality considers it practical to remove sludge content from structures. The Division will evaluate the applicability of leaving any remaining volume of sludge content in the structure on a case by case basis. Sufficient technical justification shall be provided to support such recommendation. Item F. Liner Demolition/Disposal 24. If a synthetic liner is present,remove synthetic liner,scarify/rip/disk underlying material in cases where there is no potential benefit for reuse of the structure based on projected future site use. a. If there are no historical problems with the lagoon(documented seepage,etc.)and the liner is intact after dewatering with no visible indications of seepage,soil sampling may still.be required on a case-by-case basis. b. If liner and/or lagoon issues are documented,the soil material under the synthetic liner should be sampled according to Item C,Soil and Sludge Analysis. 25. If clay liner is present,scarify/rip/disk and/or remove and reuse as cap if filling. If the liner is natural clay, sampling may be required on a case by case basis if the following conditions are not met: a. Based on existing groundwater monitoring data,no groundwater violations are present, b. Domestic wastewater systems only, c. Surficial layer of earthen material(top 6"—12")removed,and d. All sludge removed and the remaining material is only soil and not co-mingled soil/sludge. 26, If the clay liner does not meet the conditions in 425 above,the clay liner should be sampled according to Item C,Soil and Sludge Analysis. 27. If a pond or lagoon does not have a liner,the underlying soil should be sampled according to Item C,Soil and Sludge Analysis. Item G. Groundwater Post Closure Monitoring 28. For facilities with no historic groundwater monitoring,monitoring may be required based on post closure soil sample results. Contact Regional Office for directions. If groundwater monitoring is not required, permittee can petition the Division for rescission once the site is reclaimed. 29. For ponds or lagoons with historic groundwater monitoring and no groundwater violations were detected, no further groundwater monitoring will be required,as recommended by the Regional Office based on existing data. 30. For ponds or lagoons with historic groundwater monitoring and/or 15A NCAC 2L standards were exceeded,the following actions would be required: a. Maintain permit with limited actions as recommended by the Regional Office(e.g.annual groundwater monitoring and reporting). b. Continue groundwater monitoring as permitted for a minimum of three sampling events. i. If there are no further groundwater exceedances detected or exceedances show a trend of lowering toward groundwater standards,the permittee could petition the Division for permit rescission. ii. If groundwater exceedances continue at the same level,continued monitoring and or site evaluation would be required at the Regional Office Supervisor's discretion. c. In lieu of groundwater monitoring,the Permittee may provide predictive calculations,acceptable to the Director,to demonstrate groundwater standards can be met at the property boundary.

Berms/Laizoon Walls and Site Reclamation* 31. In cases where retention of municipal structures provides no value based on projected future site use, it is recommended that minimal demolition be performed to breach or remove sidewalls(dependent on the size) when the liner is demolished. Minimal demolition may be considered feasible in cases where retention of the structure or a portion thereof poses minimal risks based on conditions such as low population densities of surrounding areas,low hazard environment,low probability of encroaching development,etc. 32. For privately owned and higher risk municipal structures,more extensive structure demolition is recommended to include,but not be limited to,removal of berms/dike walls and general grading of project site. 33. If structure is completely constructed at or below grade,fill with clean material(partial or complete, depending on size)and/or grade site to minimize any hazards posed by existing conditions. 34. If structure is finished in the groundwater table,see Item C#17. 35, Stabilize the site with vegetation.Establishment of trees,grasses,and other viable cover crops should be considered to assist site stabilization and with removing any remaining nutrients. *Recognize the added value of planned reclamation efforts. Reclamation activities incorporating created artificial wetland systems,planted trees,and other pro-active actions viewed as either mitigation efforts or secondary environmental protection measures may assist with enabling the closure project to qualify for recognition and benefit from other environmental programs,such as those offered through conservation easements. Item I. Final Certifications 36. For deconstruction including berm removal,berm breaching,or liner destruction,submit a letter certified by the overseeing professional engineer that action was taken according to the approved plan,as well as all local and state regulations. 37.For wastewater disposal,submit a copy of the monitoring report that documents lagoon wastewater disposal activities,certified by the facility ORC. 38. For sludge disposal,submit a copy of the records documenting lagoon sludge disposal,certified by the licensed sludge land application contractor if land applied. If sludge was disposed of in a landfill,records from the receiving facility shall be provided. 39. Sampling results from any post-closure sampling conducted at the facility to document proper removal of sludge in accordance with the approved closure plan shall be submitted. 40.Photos of closure activities documenting conditions prior to initiating closure,closure activities,and post- closure conditions are recommended,but not required. 41.
