REGAN Secretary LINDA CULPEPPER Director NORTH CAROLINA Environmental Quality November 15, 2019 CERTIFIED MAIL 7018 2290 0001 8043 5756 RETURN RECEIPT REQUESTED Mr. Raymond Gottlieb Sandler Utilities at Mill Run, LLC 448 Viking Drive Ste 200 Virginia Beach, VA 23452 Subject: Notice of Violation: NOV-2019-LV-0839 Groundwater Quality Eagle Creek WWTP Permit No. WQ0014306 Currituck County Dear Mr. Gottlieb: Permit No. WQ0014306 was issued by the Division of Water Resources on October 8, 2015 for the continued operation of the wastewater treatment and disposal system serving the above referenced facility. A review of the permit and Groundwater Monitoring Reports showed that samples from multiple wells (monitoring wells MW-1 and MW-2) were above the groundwater standard for Total Ammonia Nitrogen. The Division of Water Resources has reason to believe that Sandler Utilities at Mill Run, LLC is responsible for activities resulting in noncompliance with North Carolina law. The self -reported GW-59 sample reports for the two wells have consistently shown elevated concentrations of total ammonia nitrogen above the State's groundwater standard of 1.5 mg/l (1,500 ug/L) found in 15A NCAC 02L .0202. This letter is to formally notify you of violations of 15A NCAC 21, (Groundwater Quality Standards) and to advise you of what you are required to do to correct these violations in accordance with 15A NCAC 2L .0106 (d). Da Q North Carolina Department of Environmental Quality I Division of Water Resources _ Washington Regional Office 1 943 Washington Square Mall I Washington, North Carolina 27889 252.946.6481 Page 2 Mr. Raymond Gottlieb November 15, 2019 According to 15A NCAC 2L .0106(d)(2) the permittee shall assess the cause, significance and extent of the violation of standards and submit the results of the investigation, and a plan and proposed schedule for corrective action to the Division. The permittee shall implement the plan as approved by and in accordance with a schedule established by the Division. Because contaminants are detected at or beyond the compliance boundary within the two monitoring wells, the permittee shall also respond in accordance with the requirements of 15A NCAC 2L .0106(f). This rule requires permittee to abate, contain or control the migration of contaminants. This rule also requires the removal, treatment or control of any primary pollution source. In addition, the rule requires the removal, treatment, or control of secondary pollution sources that would be potential continuing sources of pollutants to the groundwaters, such as contaminated soils and non -aqueous phase liquids. The site assessment shall be in accordance with 15A NCAC 2L .0106 (g) and the corrective action shall be in accordance with 15A NCAC 2L .0106 (h). We request that you respond to this notice within fifteen working days from its receipt. In your response, please confirm the Sandler Utilities at Mill Run, LLC's intent to comply with the above requirements. We appreciate your attention and prompt response in this matter. If you have questions, please do not hesitate to call either Scott Vinson or Robert Tankard at (252) 946-6481. Sincerely, Ro" T"."

Contaminated soils that threaten the quality of groundwaters shall be treated, contained, or disposed of in accordance with rules in this Chapter and in 15A NCAC 13 applicable to such activities. The treatment or disposal of contaminated soils shall be conducted in a manner that will not result in a violation of standards or North Carolina Hazardous Waste Management rules. (g) The site assessment conducted pursuant to the requirements of Paragraphs (c), (d), or (e) of this Rule, shall include: (1) The source and cause of contamination; (2) Any imminent hazards to public health and safety, as defined in G.S. 130A-2, and any actions taken to mitigate them in accordance with Paragraph (f) of this Rule; (3) All receptors and significant exposure pathways; (4) The horizontal and vertical extent of soil and groundwater contamination and all significant factors affecting contaminant transport; and (5) Geological and hydrogeological features influencing the movement, chemical, and physical character ofthe contaminants. Reports of site assessments shall be submitted to the Department as soon as practicable or in accordance with a schedule established by the Secretary. In establishing a schedule the Secretary shall consider a proposal by the person submitting the report. (h) Corrective action plans for restoration of groundwater quality, submitted pursuant to Paragraphs (c), (d), and (e) of this Rule shall include: (1) A description of the proposed corrective action and reasons for its selection; (2) Specific plans, including engineering details where applicable, for restoring groundwater quality; (3) A schedule for the implementation and operation of the proposed plan; and (4) A monitoring plan for evaluating the effectiveness ofthe proposed corrective action and the movement of the contaminant plume. (i) In the evaluation of corrective action plans, the Secretary shall consider the extent of any violations, the extent of any threat to human health or safety, the extent of damage or potential adverse impact to the environment, technology available to accomplish restoration, the potential for degradation of the contaminants in the environment, the time and costs estimated to achieve groundwater quality restoration, and the public and economic benefits to be derived from groundwater quality restoration. 0) A corrective action plan prepared pursuant to Paragraphs (c), (d), or (e) of this Rule shall be implemented using a remedial technology demonstrated to provide the most effective means, taking into consideration geological and hydrogeological conditions at the contaminated site, for restoration of groundwater quality to the level of the standards. Corrective action plans prepared pursuant to Paragraphs (c) or (e) of this Rule may request an exception as provided in Paragraphs (k), (1), (m), (r), and (s) of this Rule. (k) Any person required to implement an approved corrective action plan for a site subject to Paragraphs (c) or (e) of this Rule may request that the Secretary approve such a plan without requiring groundwater remediation to the standards. A request submitted to the Secretary under this Paragraph shall include a description of site -specific conditions, including information on the availability of public water supplies for the affected area; the technical basis for the request; and any other information requested by the Secretary to evaluate the request in accordance with Subparagraphs (1) through (7) of this Paragraph. The person making the request shall demonstrate: (1) that all sources of contamination and free product have been removed or controlled pursuant to Paragraph (f) of this Rule; la (2) that the time and direction of contaminant travel can be predicted with reasonable certainty; (3) that contaminants have not and will not migrate onto adjacent properties, or that: (A) such properties are served by an existing public water supply system dependent on surface waters or hydraulically isolated groundwater; or (B) the owners of such properties have consented in writing to the request; (4) that the standards specified in Rule .0202 of this Subchapter will be met at a location no closer than one year time of travel upgradient of an existing or foreseeable receptor, based on travel time and the natural attenuation capacity of subsurface materials or on a physical barrier to groundwater migration that exists or will be installed by the person making the request; (5) that, if the contaminant plume is expected to intercept surface waters, the groundwater discharge will not possess contaminant concentrations that would result in violations of standards for surface waters contained in 15A NCAC 02B .0200; (6) that public notice of the request has been provided in accordance with Rule .0114(b) of this Section; and (7) that the proposed corrective action plan would be consistent with all other environmental laws. (1) Any person required to implement an approved corrective action plan for a site subject to Paragraphs (c) or (e) ofthis Rule may request that the Secretary approve such a plan based upon natural processes of degradation and attenuation of contaminants. A request submitted to the Secretary under this Paragraph shall include a description of site -specific conditions, including written documentation of projected groundwater use in the contaminated area based on current state or local government planning efforts; the technical basis for the request; and any other information requested by the Secretary to evaluate the request in accordance with Subparagraphs (1) through (10) of this Paragraph. The person making the request shall demonstrate: (1) that all sources of contamination and free product have been removed or controlled pursuant to Paragraph (f) of this Rule; (2) that the contaminant has the capacity to degrade or attenuate under the site -specific conditions; (3) that the time and direction of contaminant travel can be predicted based on subsurface conditions and the contaminant's physical and chemical properties; (4) that contaminant migration will not result in any violation of applicable groundwater standards at any existing or foreseeable receptor; (5) that contaminants have not and will not migrate onto adjacent properties, or that: (A) such properties are served by an existing public water supply system dependent on surface waters or hydraulically isolated groundwater; or (B) the owners of such properties have consented in writing to the request; (6) that, if the contaminant plume is expected to intercept surface waters, the groundwater discharge will not possess contaminant concentrations that would result in violations of standards for surface waters contained in 15A NCAC 02B .0200; (7) that the person making the request will put in place a groundwater monitoring program that, based on subsurface conditions and the physical and chemical properties of the contaminant, will accurately track the degradation and attenuation of contaminants and contaminant by-products within and down gradient ofthe plume and to detect contaminants and contaminant by-products prior to their reaching any existing or foreseeable receptor at least one year's time of travel upgradient of the receptor and no greater than the distance the groundwater at the contaminated site is predicted to travel in five years; (8) that all necessary access agreements needed to monitor groundwater quality pursuant to Subparagraph (7) of this Paragraph have been or can be obtained; (9) that public notice of the request has been provided in accordance with Rule .0114(b) of this Section; and (10) that the proposed corrective action plan would be consistent with all other environmental laws. (m) The Department or any person required to implement an approved corrective action plan for a site subject to Paragraphs (c) or (e) of this Rule may request that the Secretary approve termination of corrective action. (1) A request submitted to the Secretary under this Paragraph shall include: (A) a discussion of the duration of the corrective action, the total project cost, projected annual cost for continuance and evaluation of the success of the corrective action; (B) an evaluation of alternate treatment technologies that could result in further reduction of contaminant levels, projected capital, and annual operating costs for each technology; and (C) the effects, including health and safety impacts, on groundwater users if contaminant levels remain at levels existing at the time corrective action is terminated. (2) In addition, the person making the request shall demonstrate: (A) that continuation of corrective action would not result in a significant reduction in the concentration of contaminants. This demonstration shall show the duration and degree of success of existing remedial efforts to attain standards. For the purpose of this Part, a "significant reduction" is demonstrated by showing that the asymptotic slope of the contaminants curve of decontamination is less than a ratio of 1:40 over a term of one year based on quarterly sampling; (B) that contaminants have not and will not migrate onto adjacent properties, or that: (i) such properties are served by an existing public water supply system dependent on surface waters or hydraulically isolated groundwater; or (ii) the owners of such properties have consented in writing to the request; (C) that, if the contaminant plumes are expected to intercept surface waters, the groundwater discharge will not possess contaminant concentrations that would result in violations of standards for surface waters contained in 15A NCAC 02B .0200; (D) that public notice of the request has been provided in accordance with Rule .0114(b) of this Section; and (E) that the proposed termination would be consistent with all other environmental laws. (3) The Secretary shall not authorize termination of corrective action for any area that, at the time the request is made, has been identified by a state or local groundwater use planning process for resource development. (4) The Secretary may authorize the termination of corrective action, or amend the corrective action plan after considering all the information in the request. In making the authorization, the Secretary shall consider health and safety impacts on all existing and foreseeable receptors and the impacts the contaminated plume may have if it reaches them. Upon termination of corrective action, the Secretary shall require implementation of a groundwater monitoring program that, based on subsurface conditions and the physical and chemical properties of the contaminants, will accurately track the degradation and attenuation of contaminants at a location of no less than one year's predicted time of travel upgradient of any existing or foreseeable receptor. The monitoring program shall remain in effect until there is sufficient evidence that the contaminant concentrations have been reduced to the level of the standards. For the purpose of this Part, "sufficient evidence" means that sampling and analyses demonstrate that contaminant concentrations have been reduced to the level of the standards on multiple sampling events. (n) Upon a determination by the Secretary that continued corrective action would result in no significant reduction in contaminant concentrations, and the contaminated groundwaters can be rendered potable by treatment using technologies that are in use in other applications and shown to be effective for removal of contaminants, the Secretary may designate the remaining area of degraded groundwater RS. Where the remaining degraded groundwaters cannot be made potable by such treatment, the Secretary may consider a request for reclassification of the groundwater to a GC classification as outlined in Rule .0201 of this Subchapter. (o) If at any time the Secretary determines that a new technology is available that would remediate the contaminated groundwater to the standards specified in Rule .0202 of this Subchapter, the Secretary may require the responsible party to evaluate the economic and technological feasibility of implementing the new technology in an active groundwater corrective action plan in accordance with a schedule established by the Secretary. The Secretary's determination to utilize new technology at any site or for any particular constituent shall include a consideration of the factors in Paragraph (h) of this Rule. (p) Where standards are exceeded as a result of the application of pesticides or other agricultural chemicals, the Secretary shall request the Pesticide Board or the Department of Agriculture and Consumer Services to assist the Department in determining the cause of the violation. If the violation is determined to have resulted from the use of pesticides, the Secretary shall request the Pesticide Board to take appropriate regulatory action to control the use of the chemical or chemicals responsible for, or contributing to, such violations, or to discontinue their use. (q) The approval pursuant to this Rule of any corrective action plan, or modification or termination thereof, that permits the migration of a contaminant onto adjacent property, shall not affect any private right of action by any party that may be affected by that contamination. (r) If a discharge or release is not governed by the rules in Section .0400 of this Subchapter and the increase in the concentration of a substance in excess of the standard resulted in whole or in part from a release from a commercial or noncommercial underground storage tank as defined in G.S. 143-215.94A, any person required to implement an approved corrective action plan pursuant to this Rule and seeking reimbursement for the Commercial or Noncommercial Leaking Petroleum Underground Storage Tank Cleanup Funds shall implement a convective action plan meeting the requirements of Paragraph (k) or (1) of this Rule unless the person demonstrates to the Secretary that: (1) contamination resulting from the discharge cannot qualify for approval of a plan based on the requirements of the Paragraphs; or (2) the cost of making such a demonstration would exceed the cost of implementing a corrective action plan submitted pursuant to Paragraph (c) of this Rule. (s) If a discharge or release is not governed by the rules in Section .0400 of this Subchapter and the increase in the concentration of a substance in excess of the standard resulted in whole or in part from a release from a commercial or noncommercial underground storage tank as defined in G.S. 143-215.94A, the Secretary may require any person implementing or operating a previously approved corrective action plan pursuant to this Rule to: (1) develop and implement a corrective action plan meeting the requirements of Paragraphs (k) and (1) of this Rule; or (2) seek discontinuance of corrective action pursuant to Paragraph (m) of this Rule.
