The Commission shall consider all such requests for hearing, and if the Commission determines that there is a significant public interest in holding such hearing, at least 30 days’ notice of such hearing shall be given to all persons to whom notice of intent was sent and to any other person requesting notice. At least 30 days prior to the date of hearing, the Commission shall also cause a copy of the notice thereof to be published at least one time in a newspaper having general circulation in such county. In any county in which there is more than one newspaper having general circulation in that county, the Commission shall cause a copy of such notice to be published in as many newspapers having general circulation in the county as the Commission in its discretion determines may be necessary to assure that such notice is generally available throughout the county. The Commission shall prescribe the form and content of the notices.

The Commission shall prescribe the procedures to be followed in hearings. If the hearing is not conducted by the Commission, detailed minutes of the hearing shall be kept and shall be submitted, along with any other written comments, exhibits or documents presented at the hearing, to the Commission for its consideration prior to final action granting or denying the permit.

(4) Not later than 60 days following notice of intent or, if a public hearing is held, within 90 days following consideration of the matters and things presented at such hearing, the Commission shall grant or deny any application for issuance of a new permit or for renewal of an existing permit. All permits or renewals issued by the Commission and all decisions denying application for permit or renewal shall be in writing.

(5) Repealed by Session Laws 2011-398, s. 60(b), effective July 25, 2011, and applicable to permits that are issued on or after July 1, 2011.

(6) The Commission shall not act upon an application for a new nonmunicipal domestic wastewater discharge facility until it has received a written statement from each city and county government having jurisdiction over any part of the lands on which the proposed facility and its appurtenances are to be located which states whether the city or county has in effect a zoning or subdivision ordinance and, if such an ordinance is in effect, whether the proposed facility is consistent with the ordinance. The Commission shall not approve a permit application for any facility which a city or county has determined to be inconsistent with its zoning or subdivision ordinance unless it determines that the approval of such application has statewide significance and is in the best interest of the State. An applicant for a permit shall request that each city and county government having jurisdiction issue the statement required by this subdivision by mailing by certified mail, return receipt requested, a written request for such statement and a copy of the draft permit application to the clerk of the city or county. If a local government fails to mail the statement required by this subdivision, as evidenced by a postmark, within 15 days after receiving and signing for the certified mail, the Commission may proceed to consider the permit application notwithstanding this subdivision.

(c1) Any person who is required to obtain an individual wastewater permit under this section for a facility discharging to the surface waters of the State that have been classified as nutrient sensitive waters (NSW) under rules adopted by the Commission shall not discharge more than an average annual mass load of total nitrogen than would result from a discharge of the permitted flow, determined at the time the Commission makes a finding that those waters are experiencing or are subject to excessive growth of microscopic or macroscopic vegetation, having a total nitrogen concentration of five and one-half milligrams of nitrogen per liter (5.5 mg/l). The total nitrogen concentration of 5.5 mg/l for nutrient sensitive waters required by this subsection applies only to:

(1) Facilities that were placed into operation prior to 1 July 1997 or for which an authorization to construct was issued prior to 1 July 1997 and that have a design capacity to discharge 500,000 gallons per day or more.

(2) Facilities for which an authorization to construct is issued on or after 1 July 1997.

(c2) Any person who is required to obtain an individual wastewater permit under this section for a facility discharging to the surface waters of the State that have been classified as nutrient sensitive waters (NSW) under rules adopted by the Commission where phosphorus is designated by the Commission as a nutrient of concern shall not discharge more than an average annual mass load of total phosphorus than would result from a discharge of the permitted flow, determined at the time the Commission makes a finding that those waters are experiencing or are subject to excessive growth of microscopic or macroscopic vegetation, having a total phosphorus concentration of two milligrams of phosphorus per liter (2.0 mg/l). The total phosphorus concentration of 2.0 mg/l for nutrient sensitive waters required by this subsection applies only to:

(1) Facilities that were placed into operation prior to 1 July 1997 or for which an authorization to construct was issued prior to 1 July 1997 and that have a design capacity to discharge 500,000 gallons per day or more.

(2) Facilities for which an authorization to construct is issued on or after 1 July 1997.

(c3) A person to whom subsection (c1) or (c2) of this section applies may meet the limits established under those subsections either individually or on the basis of a cooperative agreement with other persons who hold individual wastewater permits if the cooperative agreement is approved by the Commission. A person to whom subsection (c1) or (c2) of this section applies whose agreement to accept wastewater from another wastewater treatment facility that discharges into the same water body and that results in the elimination of the discharge from that wastewater treatment facility shall be allowed to increase the average annual mass load of total nitrogen and total phosphorus that person discharges by the average annual mass load of total nitrogen and total phosphorus of the wastewater treatment facility that is eliminated. If the wastewater treatment facility that is eliminated has a permitted flow of less than 500,000 gallons per day, the average annual mass load of total nitrogen or phosphorus shall be calculated from the most recent available data. A person to whom this subsection applies shall comply with nitrogen and phosphorus discharge monitoring requirements established by the Commission. This average annual load of nitrogen or phosphorus shall be assigned to the wastewater discharge allocation of the wastewater treatment facility that accepts the wastewater.

(c4) A person to whom subsection (c1) of this section applies may request the Commission to approve a total nitrogen concentration greater than that set out in subsection (c1) of this section at a decreased permitted flow so long as the average annual mass load of total nitrogen is equal to or is less than that required under subsection (c1) of this section. A person to whom subsection (c2) of this section applies may request the Commission to approve a total phosphorus concentration greater than that set out in subsection (c2) of this section at a decreased permitted flow so long as the average annual mass load of total phosphorus is equal to or is less than that required under subsection (c2) of this section. If, after any 12-month period following approval of a greater concentration at a decreased permitted flow, the Commission finds that the greater concentration at a decreased permitted flow does not result in an average annual mass load of total nitrogen or total phosphorus equal to or less than those that would be achieved under subsections (c1) and (c2) of this section, the Commission shall rescind its approval of the greater concentration at a decreased permitted flow and the requirements of subsections (c1) and (c2) of this section shall apply.

(c5) For surface waters to which the limits set out in subsection (c1) or (c2) of this section apply and for which a calibrated nutrient response model that meets the requirements of this subsection has been approved by the Commission, mass load limits for total nitrogen or total phosphorus shall be based on the results of the nutrient response model. A calibrated nutrient response model shall be developed and maintained with current data, be capable of predicting the impact of nitrogen or phosphorus in the surface waters, and incorporated into nutrient management plans by the Commission. The maximum mass load for total nitrogen or total phosphorus established by the Commission shall be substantiated by the model and may require individual discharges to be limited at concentrations that are different than those set out in subsection (c1) or (c2) of this section. A calibrated nutrient response model shall be developed by the Department in conjunction with the affected parties and is subject to approval by the Commission.

(c6) For surface waters that the Commission classifies as nutrient sensitive waters (NSW) on or after 1 July 1997, the Commission shall establish a date by which facilities that were placed into operation prior to the date on which the surface waters are classified NSW or for which an authorization to construct was issued prior to the date on which the surface waters are classified NSW must comply with subsections (c1) and (c2) of this section. The Commission shall establish the compliance schedule at the time of the classification.

(c7) For surface waters of the State that have naturally occurring low dissolved oxygen levels, as determined by the Department, permitted wastewater discharges to such surface waters shall not cause a reduction in the dissolved oxygen levels of such surface waters of more than 0.10 mg/l below the approved modeled in-stream dissolved oxygen level for the surface waters at total permitted capacity for all discharges to such surface waters.

(d) Applications and Permits for Sewer Systems, Sewer System Extensions and Pretreatment Facilities, Land Application of Waste, and for Wastewater Treatment Facilities Not Discharging to the Surface Waters of the State. –

(1) All applications for new permits and for renewals of existing permits for sewer systems, sewer system extensions and for disposal systems, and for land application of waste, or treatment works which do not discharge to the surface waters of the State, and all permits or renewals and decisions denying any application for permit or renewal shall be in writing. The Commission shall act on a permit application as quickly as possible. The Commission may conduct any inquiry or investigation it considers necessary before acting on an application and may require an applicant to submit plans, specifications, and other information the Commission considers necessary to evaluate the application. If the Commission fails to act on an application for a permit, including a renewal of a permit, within 90 days after the applicant submits all information required by the Commission, the application is considered to be approved. Permits and renewals issued in approving such facilities pursuant to this subsection shall be effective until the date specified therein or until rescinded unless modified or revoked by the Commission. Prior to acting on a permit application for the land application of bulk residuals resulting from the operation of a wastewater treatment facility, the Commission shall provide notice and an opportunity for comment from the governing board of the county in which the site of the land application of bulk residuals is proposed to be located. Local governmental units to whom pretreatment program authority has been delegated shall establish, maintain, and provide to the public, upon written request, a list of pretreatment applications received.

(2) An applicant for a permit to dispose of petroleum contaminated soil by land application shall give written notice that he intends to apply for such a permit to each city and county government having jurisdiction over any part of the land on which disposal is proposed to occur. The Commission shall not accept such a permit application unless it is accompanied by a copy of the notice and evidence that the notice was sent to each such government by certified mail, return receipt requested. The Commission may consider, in determining whether to issue the permit, the comments submitted by local governments.

(d1) Each applicant under subsections (c) or (d) for a permit (or the renewal thereof) for the operation of a treatment works for a private multi-family or single family residential development, in which the owners of individual residential units are required to organize as a lawfully constituted and incorporated homeowners’ association of a subdivision, condominium, planned unit development, or townhouse complex, shall be required to enter into an operational agreement with the Commission as a condition of any such permit granted. The agreement shall address, as necessary, construction, operation, maintenance, assurance of financial solvency, transfers of ownership and abandonment of the plant, systems, or works, and shall be modified as necessary to reflect any changed condition at the treatment plant or in the development. Where the Commission finds appropriate, it may require any other private residential subdivision, condominium, planned unit development or townhouse complex which is served by a private treatment works and does not have a lawfully constituted and incorporated homeowners’ association, and for which an applicant applies for a permit or the renewal thereof under subsections (c) or (d), to incorporate as a lawfully constituted homeowners’ association, and after such incorporation, to enter into an operational agreement with the Commission and the applicant as a condition of any permit granted under subsections (c) or (d). The local government unit or units having jurisdiction over the development shall receive notice of the application within an established comment period and prior to final decision.

(d2) No permit issued pursuant to subsection (c) of this section shall be issued or renewed for a term exceeding five years. All other permits issued pursuant to this section for which an expiration date is specified shall be issued for a term not to exceed eight years.

(d3) The Department may transfer a permit issued pursuant to subsection (d) of this section without the consent of the permit holder to a successor-owner of the property on which the permitted activity is occurring or will occur as provided in this subsection:

(1) The Department may transfer a permit if all of the following conditions are met:

3. The successor-owner is the sole claimant of the right to engage in the permitted activity.

4. There will be no substantial change in the permitted activity.

(2) The permit holder shall comply with all terms and conditions of the permit until such time as the permit is transferred.

(3) The successor-owner shall comply with all terms and conditions of the permit once the permit has been transferred.

(4) Notwithstanding changes to law made after the original issuance of the permit, the Department may not impose new or different terms and conditions in the permit without the prior express consent of the successor-owner.

(e) Administrative Review. – A permit applicant, a permittee, or a third party who is dissatisfied with a decision of the Commission may commence a contested case by filing a petition under N.C. Gen. Stat. § 150B-23 within 30 days after the Commission notifies the applicant or permittee of its decision. If the permit applicant, the permittee, or a third party does not file a petition within the required time, the Commission’s decision is final and is not subject to review.

(f) Local Permit Programs for Sewer Extension and Reclaimed Water Utilization. – Municipalities, counties, local boards or commissions, water and sewer authorities, or groups of municipalities and counties may establish and administer within their utility service areas their own general permit programs in lieu of State permit required in N.C. Gen. Stat. § 143-215.1(a)(2), (3), and (8) above, for construction, operation, alteration, extension, change of proposed or existing sewer system, subject to the prior certification of the Commission. For purposes of this subsection, the service area of a municipality shall include only that area within the corporate limits of the municipality and that area outside a municipality in its extraterritorial jurisdiction where sewer service or a reclaimed water utilization system is already being provided by the municipality to the permit applicant or connection to the municipal sewer system or a reclaimed water utilization system is immediately available to the applicant; the service areas of counties and the other entities or groups shall include only those areas where sewer service or a reclaimed water utilization system is already being provided to the applicant by the permitting authority or connection to the permitting authority’s system is immediately available. No later than the 180th day after the receipt of a program and statement submitted by any local government, commission, authority, or board the Commission shall certify any local program that does all of the following:

(f1) The Commission may deny, suspend, or revoke certification of a local program upon a finding that a violation of the provisions in subsection (f) of this section has occurred. A denial, suspension, or revocation of a certification of a local program shall be made only after notice and a public hearing. If the failure of a local program to carry out this subsection creates an imminent hazard, the Commission may summarily revoke the certification of the local program. Chapter 150B of the N.C. Gen. Stat. does not apply to proceedings under this subsection.

(f2) Notwithstanding any other provision of subsections (f) and (f1) of this section, if the Commission determines that a sewer system, treatment works, or disposal system is operating in violation of the provisions of this Article and that the appropriate local authorities have not acted to enforce those provisions, the Commission may, after written notice to the appropriate local government, take enforcement action in accordance with the provisions of this Article.

(f3) The permittee for a wastewater treatment system may calculate its wastewater flows for new dwelling units, including units that have yet to be connected and for which the permittee has allocated capacity, at 75 gallons per day per bedroom, or at a lower rate approved by the Department.

(f4) No permits for sewer line extensions shall be issued to wastewater treatment systems owned or operated by municipalities, counties, sanitary districts, or public utilities unless the systems meet the following requirements:

(1) Prior to actual flow exceeding eighty percent (80%) of the system’s permitted hydraulic capacity, based on the average flow during the last calendar year, the permittee shall submit an engineering evaluation of its future wastewater treatment, utilization, and disposal needs. This evaluation shall outline plans for meeting future wastewater treatment, utilization, or disposal needs by either expansion of the existing system, elimination or reduction of extraneous flows, or water conservation and shall include the source of funding for the improvements. If expansion is not proposed or is proposed for a later date, a justification shall be made that wastewater treatment needs will be met based on past growth records and future growth projections and, as appropriate, shall include conservation plans or other measures to achieve waste flow reductions.

(2) Prior to actual flow exceeding ninety percent (90%) of the system’s permitted hydraulic capacity, based on the average flow during the last calendar year, the permittee shall obtain all permits needed for the expansion of the wastewater treatment, utilization, or disposal system and, if construction is needed, submit final plans and specifications for expansion, including a construction schedule. If expansion is not proposed or is proposed for a later date, a justification shall be made that wastewater treatment needs will be met based on past growth records and future growth projections and, as appropriate, shall include conservation plans or other specific measures to achieve waste flow reductions.

(3) The Director shall allow permits to be issued to facilities that are exceeding the eighty percent (80%) or ninety percent (90%) disposal capacity if the additional flow is not projected to result in the facility exceeding its permitted hydraulic capacity, the facility is in compliance with all other permit limitations and requirements, and adequate progress is being made in developing the required engineering evaluations or plans and specifications. In determining the adequacy of the progress, the Director shall consider the projected flows, the complexity and scope of the work to be completed, and any projected environmental impacts.

(f5) A permittee for a wastewater treatment system, who has signed a contract for the expansion of its wastewater treatment system, utilization, or disposal system and whose current system is located in a county with a projected population growth rate above two percent (2%) annually or is located in one of the top twenty percent (20%) of the fastest growing counties in the State, by population, and is meeting flow and pollutant discharge limits set out in the system’s current permit, may allocate one hundred ten percent (110%) of its existing system’s hydraulic capacity and increase the allocation amount to one hundred fifteen percent (115%) when the expansion of its system is within 24 months of completion, but may not allocate more than the permitted projected capacity after expansion without approval by the Department. Nothing in this subsection shall be construed to limit the Department from authorizing allocations above one hundred fifteen percent (115%) of a system’s hydraulic capacity.

(g) Any person who is required to hold a permit under this section shall submit to the Department a written description of his current and projected plans to reduce the discharge of waste and pollutants under such permit by source reduction or recycling. The written description shall accompany the payment of the annual permit fee. The written description shall also accompany any application for a new permit, or for modification of an existing permit, under this section. The written description required by this subsection shall not be considered part of a permit application and shall not serve as the basis for the denial of a permit or permit modification.
