(a) General provisions.
(1) Purpose and policy. This section sets forth uniform requirements for direct and indirect contributors into the wastewater collection and treatment system for the Town of Surf City hereafter referred to as the town, and enables the town to comply with all applicable state and federal laws, including the Clean Water Act (33 United States Code § 1251 et seq.) and the General Pretreatment Regulations (40 CFR, Part 403). The objectives of this section are:
a. To prevent the introduction of pollutants into the municipal wastewater system which will interfere with the operation of the system or contaminate the resulting sludge;
b. To prevent the introduction of pollutants into the municipal wastewater system which will pass-through the system, inadequately treated, into any waters of the state or otherwise be incompatible with the system;
c. To promote reuse and recycling of industrial wastewater and sludges from the municipal system;
d. To protect both municipal personnel who may be affected by sewage, sludge, and effluent in the course of their employment as well as protecting the general public;
e. To provide for equitable distribution of the cost of operation, maintenance and improvement of the municipal wastewater system; and
f. To ensure that the municipality complies with its NPDES or non discharge permit conditions, sludge use and disposal requirements and any other federal or state laws to which the municipal wastewater system is subject.
This section provides for the regulation of direct and indirect contributors to the municipal wastewater system, through the issuance of permits to certain nondomestic users and through enforcement of general requirements for the other users, authorizes monitoring and enforcement activities, requires user reporting and provides for the setting of fees for the equitable distribution of costs resulting from the program established herein.
This section shall apply to all users of the municipal wastewater system, as authorized by G.S. 160A-312 and/or 153A-275. The town shall designate an administrator of the POTW and pretreatment program hereafter referred to as the POTW director. Except as otherwise provided herein, the POTW director shall administer, implement, and enforce the provisions of this section. Any powers granted to or imposed upon the POTW director may be delegated by the POTW director to other town personnel. By discharging wastewater into the municipal wastewater system, industrial users located outside the town limits agree to comply with the terms and conditions established in this section, as well as any permits, enforcement actions, or orders issued hereunder.

a. The user charge shall reflect, at least, the cost of debt service, operation and maintenance (including replacement) of the POTW.
b. Each user shall pay its proportionate cost based on volume of flow.
c. The manager of the town shall review annually the sewage contributions of users, the total costs of debt service, operation and maintenance of the POTW and will make recommendations to the council serving the town for adjustments in the schedule of charges and fees as necessary.
d. Charges for flow to the POTW not directly attributable to the users shall be distributed among all users of the POTW based upon the volume of flow of the users.
(3) Surcharges. The amount of the surcharges will be based upon the volume of flow and the character and concentration of the constituents of the wastewater:
a. The volume of flow used in determining the total discharge of wastewater for payment of user charges and surcharges shall be based on the following:
1. Metered water consumption as shown in the records of meter readings maintained by the town; or
2. If required by the town or at the individual dischargers option, other flow monitoring devices which measure the actual volume of wastewater discharged to the sewer. Such devices shall be accessible and safely located, and the measuring system shall be installed in accordance with plans approved by the town. The metering system shall be installed and maintained at the user's expense according to arrangements that may be made with the town.
3. Where any user procures all or part of his water supply from sources other than the town, the user shall install and maintain at his own expense a flow measuring device of a type approved by the town.

(8) Notice of violation/repeat sampling and reporting. If sampling performed by a user indicates a violation, the user must notify the POTW director within twenty-four (24) hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the POTW director within thirty (30) days after becoming aware of the violation. The user is not required to resample if the POTW director monitors at the user's facility at least once a month, or if the POTW director samples between the user's initial sampling and when the user receives the results of this sampling.
(9) Notification of the discharge of hazardous waste. The town prohibits the discharge of any hazardous wastes without notification and approval of the POTW director.
a. Any user who commences the discharge of hazardous waste shall notify the POTW, the EPA Regional Waste Management Division Director, and State hazardous waste authorities, in writing, of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR Part 261. Such notification must include the name of the hazardous waste as set forth in 40 CFR Part 261, the EPA hazardous waste number, and the type of discharge (continuous, batch, or other). If the user discharges more than one hundred (100) kilograms of such waste per calendar month to the POTW, the notification also shall contain the following information to the extent such information is known and readily available to the user: an identification of the hazardous constituents contained in the wastes, an estimation of the mass and concentration of such constituents in the waste stream discharge during the calendar month, and an estimation of the mass of constituents in the waste stream expected to be discharged during the following twelve (12) months. All notifications must take place no later than one hundred and eighty (180) days after the discharge commences. Any notification under this paragraph need be submitted only once for each hazardous waste discharge. However, notifications of changed conditions must be submitted under subsection (e)(5), of this section. The notification requirement in this section does not apply to pollutants already reported by users subject to categorical pretreatment standards under the self-monitoring requirements of subsections (e)(1), (3), and (4), of this section.
b. Dischargers are exempt from the requirements of paragraph a., above, during a calendar month in which they discharge no more than fifteen (15) kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specific in 40 CFR 261.30(d) and 261.33(e). Discharge of more than fifteen (15) kilograms of nonacute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), requires a one-time notification. Subsequent months during which the user discharges more than such quantities of any hazardous waste do not require additional notification.
c. In the case of any new regulation under section 3001 of RCRA identifying additional characteristics of hazardous waste or listing any additional substance as a hazardous waste, the user must notify the POTW director, the EPA Regional Waste Management Waste Division Director, and state hazardous waste authorities of the discharge of such substance within ninety (90) days of the effective date of such regulations.
d. In the case of any notification made under this section, the user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical.
e. This provision does not create a right to discharge any substance not otherwise permitted to be discharged by this section, a permit issued thereunder, or any applicable federal or state law.
(10) Analytical requirements. All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report shall be performed in accordance with the techniques prescribed in 40 CFR Part 136, unless otherwise specified in an applicable categorical pretreatment standard. If 40 CFR Part 136 does not contain sampling or analytical techniques for the pollutant in question, sampling and analyses must be performed in accordance with procedures approved by EPA.
(11) Sample collection.
a. Except as indicated in subsection b., below, the user must collect wastewater samples using flow proportional composite collection techniques. In the event flow proportional sampling is infeasible, the POTW director may authorize the use of time proportional sampling or a minimum of four (4) grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged. In addition, grab samples may be required to show compliance with instantaneous discharge limits.
b. Samples for oil and grease, temperature, pH, cyanide, phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques.
(12) Timing. Written reports will be deemed to have been submitted on the date postmarked. For reports which are not mailed, postage prepaid, into a mail facility serviced by the United States Postal Service, the date of receipt of the report shall govern.
(13) Recordkeeping. Users subject to the reporting requirements of this section shall retain, and make available for inspection and copying, all records of information obtained pursuant to any monitoring activities required by this section and any additional records of information obtained pursuant to monitoring activities undertaken by the user independent of such requirements. Records shall include the date, exact place, method, and time of sampling, and the name of the person(s) taking the samples; the dates analyses were performed; who performed the analyses; the analytical techniques or methods used; and the results of such analyses. These records shall remain available for a period of at least three (3) years. This period shall be automatically extended for the duration of any litigation concerning the user or the town, or where the user has been specifically notified of a longer retention period by the POTW director.
(f) Compliance monitoring.
(1) Monitoring facilities.
a. The town requires the user to provide and operate at the user's own expense, monitoring facilities to allow inspection, sampling, and flow measurement of the building sewer and/or internal drainage systems. The monitoring facility should normally be situated on the user's premises, but the town may, when such a location would be impractical or cause undue hardship on the user, allow the facility to be constructed in the public street or sidewalk area and located so that it will not be obstructed by landscaping or parked vehicles.
b. There shall be ample room in or near such sampling manhole or facility to allow accurate sampling and preparation of samples for analysis. The facility, sampling, and measuring equipment shall be maintained at all times in a safe and proper operating condition at the expense of the user.
c. Whether constructed on public or private property, the sampling and monitoring facilities shall be provided in accordance with the requirements of the town and all applicable local construction standards and specifications. Construction shall be completed within ninety (90) days following written notification by the town.
(2) Inspection and sampling. The town will inspect the facilities of any user to ascertain whether the purpose of this section is being met and all requirements are being complied with. Persons or occupants of premises where wastewater is created or discharged shall allow the town, approval authority and EPA or their representative ready access at all reasonable times to all parts of the premises for the purposes of inspection, sampling, records examination and copying or in the performance of any of their duties. The town, approval authority and EPA shall have the right to set up on the user's property such devices as are necessary to conduct sampling, inspection, compliance monitoring and/or metering operations. Where a user has security measures in force which would require proper identification and clearance before entry into their premises, the user shall make necessary arrangements with their security guards so that upon presentation of suitable identification, personnel from the town, approval authority and EPA will be permitted to enter, without delay, for the purposes of performing their specific responsibilities. Denial of the POTW director's approval authority's, or EPA's access to the user's premises shall be a violation of this section.
(3) Search warrants. If the POTW director, approval authority, or EPA has been refused access to a building, structure, or property, or any part thereof, and is able to demonstrate probable cause to believe that there may be a violation of this section, or that there is a need to inspect and/or sample as part of a routine inspection and sampling program of the town designed to verify compliance with this section or any permit or order issued hereunder, or to protect the overall public health, safety and welfare of the community, then the POTW director, approval authority, or EPA may seek issuance of a search warrant from the court having jurisdiction within the town.
(g) Confidential information.
(1) Information and data on a user obtained from reports, questionnaires, permit applications, permits and monitoring programs and from inspections shall be available to the public or other governmental agency without restriction unless the user specifically requests and is able to demonstrate to the satisfaction of the POTW director that the release of such information would divulge information, processes or methods of production entitled to protection as trade secrets of the user. Any such request must be asserted at the time of submission of the information or data.
(2) When requested by the person furnishing a report, the portions of a report which might disclose trade secrets or secret processes shall not be made available for inspection by the public, but shall be made available upon written request to governmental agencies for uses related to this section, the National Pollutant Discharge Elimination System (NPDES) Permit, non discharge permit and/or the pretreatment programs; provided, however, that such portions of a report shall be available for use by the State or any state agency in judicial review or enforcement proceedings involving the person furnishing the report. Wastewater constituents and characteristics will not be recognized as confidential information.
(3) All records relating to compliance with pretreatment standards shall be made available to officials of the approval authority and EPA upon request.
(1) Administrative remedies.
a. Notification of violation. Whenever the POTW director finds that any user has violated or is violating this section, wastewater permit, or any prohibition, limitation or requirements contained therein or any other pretreatment requirement the POTW director may serve upon such a person a written notice stating the nature of the violation. Within thirty (30) days from the date of this notice, an explanation for the violation and a plan for the satisfactory correction thereof shall be submitted to the town by the user. Submission of this plan does not relieve the discharger of liability for any violations occurring before or after receipt of the notice of violation.
b. Consent orders. The POTW director is hereby empowered to enter into consent orders, assurances of voluntary compliance, or other similar documents establishing an agreement with the person responsible for the noncompliance. Such orders will include specific action to be taken by the discharger to correct the noncompliance within a time period also specified by the order. Consent orders shall have the same force and effect as an administrative order issued pursuant to subsection (h)(1)d., below.
c. Show cause hearing.
1. The POTW director may order any user who causes or is responsible for an unauthorized discharge, has violated this section or is in noncompliance with a wastewater discharge permit to show cause why a proposed enforcement action should not be taken. In the event the POTW director determines that a show cause order should be issued, a notice shall be served on the user specifying the time and place for the hearing, the proposed enforcement action, the reasons for such action, and a request that the user show cause why this proposed enforcement action should not be taken. The notice of the hearing shall be served personally or by registered or certified mail (return receipt requested) at least ten (10) days before the hearing. Service may be made on any agent or officer of a corporation.
2. The POTW director shall review the evidence presented at the hearing and determine whether the proposed enforcement action is appropriate.
3. A show cause hearing under this section is not a prerequisite to the assessment of a civil penalty under subsection (h)(2) nor is any action or inaction taken by the POTW director under this section subject to an administrative appeal under subsection (d)(2)h.
d. Administrative orders. When the POTW director finds that user has violated or continues to violate this section, permits or orders issued hereunder, or any other pretreatment requirement the POTW director may issue an order to cease and desist all such violations and direct those persons in noncompliance to do any of the following:
1. Immediately comply with all requirements;
2. Comply in accordance with a compliance time schedule set forth in the order;
3. Take appropriate remedial or preventive action in the event of a continuing or threatened violation;
4. Disconnect unless adequate treatment facilities, devices or other related appurtenances are installed and properly operated within a specified time period.
e. Emergency suspensions.
1. The POTW director may suspend the wastewater treatment service and/or wastewater permit when such suspension is necessary in order to stop an actual or threatened discharge which presents or may present an imminent or substantial endangerment to the health or welfare of persons or the environment, interferes with the POTW or causes the POTW to violate any condition of its NPDES or mon discharge permit.
2. Any user notified of a suspension of the wastewater treatment service and/or the wastewater permit shall immediately stop or eliminate the contribution. A hearing will be held within fifteen (15) days of the notice of suspension to determine whether the suspension may be lifted or the user's waste discharge permit terminated. In the event of a failure to comply voluntarily with the suspension order, the POTW director shall take such steps as deemed necessary including immediate severance of the sewer connection, to prevent or minimize damage to the POTW system or endangerment to any individuals. The POTW director shall reinstate the wastewater permit and the wastewater treatment service upon proof of the elimination of the noncompliant discharge. The industrial user shall submit a detailed written statement describing the causes of the harmful contribution and the measures taken to prevent any future occurrence to the POTW director prior to the date of the above-described hearing.
f. Termination of permit. Any user, who violates the following conditions of this section, or applicable state and federal regulations, is subject to having its permit terminated:
1. Failure to accurately report the wastewater constituents and characteristics of his discharge;
2. Failure to report significant changes in operations, or wastewater constituents and characteristics;
3. Refusal of reasonable access to the user's premises for the purpose of inspection or monitoring; or,
4. Violation of conditions of the permit.
Noncompliant users will be notified of the proposed termination of their wastewater permit and will be offered an opportunity to show cause under subsection (h)(1), of this section why the proposed action should not be taken.
(2) Civil penalties.
a. Any user who is found to have failed to comply with any provision of this section, or the orders, rules, regulations and permits issued hereunder, may be fined up to twenty-five thousand dollars ($25,000.00) per day per violation.
1. Penalties between ten thousand dollars ($10,000.00) and twenty-five thousand dollars ($25,000.00) per day per violation may be assessed against a violator only if:
a. For any class of violation, only if a civil penalty has been imposed against the violator within the five (5) years preceding the violation, or
b. In the case of failure to file, submit, or make available, as the case may be, any documents, data, or reports required by this section, or the orders, rules, regulations and permits issued hereunder, only if the POTW director determines that the violation was intentional and a civil penalty has been imposed against the violator within the five (5) years preceding the violation.
b. In determining the amount of the civil penalty, the POTW director shall consider the following:
1. The degree and extent of the harm to the natural resources, to the public health, or to public or private property resulting from the violation;
2. The duration and gravity of the violation;
3. The effect on ground or surface water quantity or quality or on-air quality;
4. The cost of rectifying the damage;
5. The amount of money saved by noncompliance;
6. Whether the violation was committed willfully or intentionally;
7. The prior record of the violator in complying or failing to comply with the pretreatment program;
8. The costs of enforcement to the town.
c. Appeals of civil penalties assessed in accordance with this section shall be as provided in subsection (d)(2)h.
(3) Other available remedies. Remedies, in addition to those previously mentioned in this section, are available to the POTW director who may use any single one (1) or combination against a noncompliant user. Additional available remedies include, but are not limited to:
a. Criminal violations. The district attorney for the applicable judicial district may, at the request of the town, prosecute noncompliant users who violate the provisions of G.S. 143-215.6B. [Note: Under North Carolina law, it is a crime to negligently violate any term, condition, or requirement of a pretreatment permit, or negligently fail to apply for a pretreatment permit, issued by local governments (G.S. 143-215.6B(f)), to knowingly and willfully violate any term, condition, or requirement of a pretreatment permit, or knowingly and willfully fail to apply for a pretreatment permit, issued by local governments (G.S. 143-215.6B(g)), to knowingly violate any term, condition, or requirement of a pretreatment permit issued by local governments, or knowingly fail to apply for a pretreatment permit, knowing at the time that a person is placed in imminent danger of death or serious bodily injury, (G.S. 143-215.6B(h)), and to falsify information required under G.S. Ch. 143, Art. 21 (G.S. 143-215.6B(i)).]
b. Injunctive relief. Whenever a user is in violation of the provisions of this section or an order or permit issued hereunder, the POTW director, through the town attorney, may petition the Superior Court of Justice for the issuance of a restraining order or a preliminary and permanent injunction which restrains or compels the activities in question.
c. Water supply severance. Whenever a user is in violation of the provisions of this section or an order or permit issued hereunder, water service to the user may be severed and service will only recommence, at the user's expense, after it has satisfactorily demonstrated ability to comply.
d. Public nuisances. Any violation of the prohibitions or effluent limitations of this section or of a permit or order issued hereunder, is hereby declared a public nuisance and shall be corrected or abated as directed by the POTW director. Any person(s) creating a public nuisance shall be subject to the provisions of the appropriate ordinances of the town governing such nuisances, including reimbursing the POTW for any costs incurred in removing, abating or remedying said nuisance.
(4) Remedies nonexclusive. The remedies provided for in this section are not exclusive. The POTW director may take any, all, or any combination of these actions against a noncompliant user. Enforcement of pretreatment violations will generally be in accordance with the town's enforcement response plan. However, the POTW director may take other action against any user when the circumstances warrant. Further, the POTW director is empowered to take more than one (1) enforcement action against any noncompliant user.
(i) Annual publication of significant noncompliance. At least annually, the POTW director shall publish in the largest daily newspaper circulated in the service area, a list of those users which were found to be in significant noncompliance, also referred to as reportable noncompliance in 15A NCAC 2H .0903(b)(10), with applicable pretreatment standards and requirements, during the previous twelve (12) months.
(j) Affirmative defenses to discharge violations.
a. An upset shall constitute an affirmative defense to an action brought for noncompliance with categorical pretreatment standards if the requirements of subparagraph b., below, are met.
b. A user who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:
1. An upset occurred and the user can identify the cause(s) of the upset;
2. The facility was at the time being operated in a prudent and workman-like manner and in compliance with applicable operation and maintenance procedures; and
3. The user has submitted the following information to the POTW director within twenty-four (24) hours of becoming aware of the upset [if this information is provided orally, a written submission must be provided within five (5) days]:
i. A description of the indirect discharge and cause of noncompliance;
ii. The period of noncompliance, including exact dates and times or, if not corrected, the anticipated time the noncompliance is expected to continue; and
iii. Steps being taken and/or planned to reduce, eliminate, and prevent recurrence of the noncompliance.
c. In any enforcement proceeding, the user seeking to establish the occurrence of an upset shall have the burden of proof.
d. Users will have the opportunity for a judicial determination on any claim of upset only in an enforcement action brought for noncompliance with categorical pretreatment standards.
e. Users shall control production of all discharges to the extent necessary to maintain compliance with categorical pretreatment standards upon reduction, loss, or failure of its treatment facility until the facility is restored or an alternative method of treatment is provided. This requirement applies in the situation where, among other things, the primary source of power of the treatment facility is reduced, lost, or fails.
(2) Prohibited discharge standards defense. A user shall have an affirmative defense to an enforcement action brought against it for noncompliance with the general prohibitions in subsection (b)(1)a., of this section or the specific prohibitions in subsections (b)(1)b.2., 3., and 5.—7. of this section if it can prove that it did not know, or have reason to know, that its discharge, alone or in conjunction with discharges from other sources, would cause passthrough or interference and that either:
a. A local limit exists for each pollutant discharged and the user was in compliance with each limit directly prior to, and during, the pass-through or interference; or
b. No local limit exists, but the discharge did not change substantially in nature or constituents from the user's prior discharge when [the town] was regularly in compliance with its NPDES permit, and in the case of interference, was in compliance with applicable sludge use or disposal requirements.
a. 1. If a user knows in advance of the need for a bypass, it shall submit prior notice to the POTW director, at least ten (10) days before the date of the bypass, if possible.
2. A user shall submit oral notice to the POTW director of an unanticipated bypass that exceeds applicable pretreatment standards within twenty-four (24) hours from the time it becomes aware of the bypass. A written submission shall also be provided within five (5) days of this time the user becomes aware of the bypass. The written submission shall contain a description of the bypass and its cause; the duration of the bypass, including exact dates and times, and, if the bypass has not been corrected, the anticipated time it is expected to continue; and steps taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass. The POTW director may waive the written report on a case-by-case basis if the oral report has been received within twenty-four (24) hours.
b. 1. Bypass is prohibited, and the POTW director may take an enforcement action against a user for a bypass, unless:
i. Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;
ii. There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and
iii. The user submitted notices as required under paragraph b. of this section.
2. The POTW director may approve an anticipated bypass, after considering its adverse effects, if the POTW director determines that it will meet the three (3) conditions listed in subparagraph b.1., of this section.
