Director RONALD BUCK — PARTNER LINGO PARTNERSHIP 5200 OLD HARDING ROAD FRANKLIN, TENNESSEE 37064 Dear Mr. Buck, NORTH CAROLINA Environmental Quality January 31, 2023 Subject: Penult No. WQ0003924 Permit Rescission Denial Linco Partnership — Lincolnton WWTF Wastewater Irrigation System Lincoln County This letter is in response to your permit rescission request received September 21, 2022. The Mooresville Regional Office has reviewed your permit rescission request and has determined that the Permittee needs to address the following item: 1. The Permittee shall submit a Closure Plan for the wastewater treatment, storage, and irrigation facilities. Attached is a Division -issued Memorandum titled "Guidelines for the Closure of Permitted Wastewater Ponds and Lagoons" for your reference. Accordingly, the Division has denied your permit rescission request. Pursuant to 15A NCAC 02T .0105 , "the Permittee shall comply with all permit conditions and requirements until the waste treatment systems authorized by the permit are properly closed or subsequently permitted by another permit issued by the appropriate permitting authority for that activity." Please contact the Mooresville Regional Office at (704) 663-1699 if you need assistance completing the above item. Once the Permittee has addressed this item, you may resubmit your permit rescission request via the Non -Discharge online portal. If you need additional information concerning this letter, please contact Nathaniel Thornburg at (919) 707-3653 or nathaniel.thornburg&ncdenr.gov. Sincerely, DDocuSigned by: T..u. "WoN83 Richard E.

Background: Man-made treatment ponds and lagoon type structures are used to contain fluids and semi -solids for a variety of reasons. As these ponds and lagoons become no longer necessary, the structure needs to be abandoned in an environmentally friendly manner. The Groundwater Section's major concern with the elimination of these stnictures is that groundwater remains protected both during and after abandonment. Each structure must be considered for its unique circumstances on a case -by -case basis. Regulations relevant to the abandonment of ponds and lagoons for ground waters of the state include the Classifications and Water Quality Standards found in Title 1 5A NCAC 2L. Other pertinent standards and regulations maybe found in the DENR Land Resources regulations pertaining to Sedimentation and Erosion Control and Dana Safety, the DENR "Waste Management regulations pertaining to the disposal of wastes and sludge, and the NCDOT regulations pertaining to transportation of materials on public highways. Lagoons for animal ID waste are regulated under the federal NRCS Standards. Recommended Procedure: The major elements of pond and lagoon structures include the contents, the walls, the floor and the liner, if one exists. Each element must be characterized for its quantity and material properties in order to prepare a closure plan. Guidelines for the preparation of this plan are described in the following steps: 1) Collect and assemble field information by characterizing the structural elements and liquid contents, including bottom sludge in the impoundment. Sampling will be required in most situations, and the types of sampling and analyses will depend on factors such as what the lagoon was used for, its construction materials (earthen, concrete, natural or synthetic liner), and size. The samples must be representative of the medium sampled, and the rationale for the depths, locations and number of samples should be justified and documented in preparation of being legally defensible. The sampling must be performed under the direction Lagoon Closure final,doc Page 1 of 3 of a qualified individual and analyzed by a DWQ Certified Laboratory. <y` y 2) Prepare and submit a Closure Plan to the DWQ regional office at least 30 days prior to commencing deconstruction activities. This should include as a minimum: a. the quantity and characteristics (TCLP, nutrients, metals) of the materials for disposal (contents, walls, floor and liner), including the calculations used to determine volumes, b. an assessment of alternatives (actions, costs and timing) in sufficient detail to select an optimum approach consistent with minimal groundwater impact, c. a proposed method for removal/disposal, including the abandonment and salvage of any physical equipment, and a timetable for the project, d. site reclamation plan and section view of the treatment, storage and disposal area(s), e. vicinity map, and f. location map to scale showing items such as the location of sampling points, existing monitoring and supply wells (within 500 feet), depth to groundwater, direction of groundwater flow, roads, strictures, and rock outcrops. 3) If the structure is to be retained for an ornamental pond, storage or any other function other than for treatment, then the Closure Plan will need to demonstrate that the residuals of treatment (e.g. physical connections, bottom sludge, coliforms, nutrients and metals) conform to all appropriate surface water standards. 4) If the structure is to be abandoned in place (totally or partially), sampling of the underlying native soil, whether it has a natural or synthetic liner, is required. If the sampling determines that the soil is contaminated, then the Closure flan will need to demonstrate, by modeling or numerical calculations, that leaving the contents and or stricture materials in place will not cause a contravention of the groundwater quality standards in the groundwater beneath the structure. If the modeling does not demonstrate this, than removal or treatment of the soils must be included as part of the Closure Plan. If it were an earthen structure, the preferable approach would be to completely eliminate the walls and incorporate the material in the existing site. 5) Any land disturbing activity associated with the closure activities that affect more than one (1) acre of land must have an erosion and sediment control plan approved by the Land Quality Section of the Division of Land Resources. NC General Statute 113A-57(4) requires this plan to be submitted at least thirty (30) days prior to beginning the land -disturbing activity. Closure Documentation: Upon completion of the closure, the owner should submit documentation to the DWQ regional office with the following: 1) A description of all actions taken and elates relative to the abandonment. Lagoon Closine final.doo Page 2 of 3 2) Copies of all pertinent correspondence with private, Iocal, state and/or federal agencies. 3) Ultimate disposal sites with weigh tickets or processing verifications, as appropriate. 4) Certification by a Professional Engineer (PE) or Professional Geologist (PG) if the pond or lagoon: a. is greater than five (5) acres in total area, b. contains hazardous substances as defined by TCLP tests, or c. involves a breaching of a darn, which could impose a safety hazard to persons or property below it.
