This chapter sets forth uniform requirements for direct and indirect contributors into the wastewater collection and treatment system for the Town of Wilkesboro, hereafter referred to as the Town of Wilkesboro, 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).
(A) The objectives of this chapter are:
(1) To prevent the introduction of pollutants and wastewater discharges into the municipal wastewater system which will interfere with the operation of the system or contaminate the resulting sludge;
(2) To prevent the introduction of pollutants and wastewater discharges 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;
(3) To promote reuse and recycling of industrial wastewater and sludges from the municipal system;
(4) 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;
(5) To provide for equitable distribution of the cost of operation, maintenance and improvement of the municipal wastewater system; and
(6) 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.
(B) This chapter provides for the regulation of direct and indirect contributors to the municipal wastewater system, through the issuance of permits to certain non-domestic 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.
(C) This chapter 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 Publicly Owned Treatment Works or 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 chapter. Any powers granted to or imposed upon the POTW Director may be delegated by the POTW Director to other town personnel.
(D) By discharging wastewater into the town wastewater system, industrial users located outside the town limits agree to comply with the terms and conditions established in this chapter, as well as any permits, enforcement actions, or orders issued hereunder.

(J) Pretreatment of wastewater.
(1) Pretreatment facilities. Users shall provide wastewater treatment as necessary to comply with this chapter and wastewater permits issued under § 53.05(B) and shall achieve compliance with all National categorical pretreatment standards, local limits, and the prohibitions set out in § 53.03(A) within the time limitations as specified by EPA, the state, or the POTW Director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the town for review, and shall be approved by the POTW Director before construction of the facility. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the town under the provisions of this chapter. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be approved by the POTW Director prior to the user's initiation of the changes.
(2) Additional pretreatment measures.

(b) The POTW Director may require any person discharging into the POTW to install and maintain, on their property and at their expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
(c) Grease, oil, and sand interceptors shall be provided when, in the opinion of the POTW Director, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil, or sand; except that such interceptors shall not be required for residential users. All interception units shall be of type and capacity approved by the POTW Director and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the user at their expense.
(d) Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
(K) Accidental discharge/slug control plans.
(1) The POTW Director shall evaluate whether each significant industrial user needs a plan or other action to control and prevent slug discharges and accidental discharges as defined in § 53.02.

(4) 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.
(5) This provision does not create a right to discharge any substance not otherwise permitted to be discharged by this chapter, a permit issued thereunder, or any applicable federal or state law.
(J) Analytical requirements. All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report shall be performed by a laboratory certified by the state to perform the wastewater analyses in accordance with the techniques prescribed in 40 CFR Part 136, unless otherwise specified in an applicable categorical pretreatment standard or unless otherwise performed in accordance with procedures approved by EPA or town. 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 and the town.
(K) Grab and composite sample collection.
(1) All wastewater samples must be representative of the user's discharge. Wastewater monitoring and low measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of a user to keep its monitoring facility in good working order shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
(2) Grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide, volatile organic compounds, and any other pollutants as required by 40 CFR 136. The POTW shall determine the number of grabs necessary to be representative of the user's discharge. See 40 CFR 403.12(g)(5) for additional grab sample number requirements for BMR and 90-Day Compliance Reports. Additionally, the POTW Director may allow collection of multiple grabs during a 24-hour period which are composited prior to analysis as allowed under 40 CFR 136.
(3) Composite samples. All wastewater composite samples shall be collected with a minimum of hourly aliquots or grabs for each hour that there is a discharge. All wastewater composite samples shall be collected using flow proportional composite collection techniques, unless time-proportional composite sampling or grab sampling is authorized by the POTW Director. When authorizing time-proportional composites or grabs, the samples must be representative and the decision to allow the alternative sampling must be documented.
(L) 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.
(M) Record keeping. Users subject to the reporting requirements of this chapter shall retain, and make available for inspection and copying, all records of information obtained pursuant to any monitoring activities required by this chapter 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 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.
(N) Electronic reporting. The POTW Director may develop procedures for receipt of electronic reports for any reporting requirements of this chapter. Such procedures shall comply with 40 CFR Part 3. These procedures shall be enforceable under § 53.09.
(Ord. passed 12-3-2012)
(A) (1) Monitoring facilities. 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.
(2) 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.
(3) 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 90 days following written notification by the town.
(B) Inspection and sampling. The town will inspect the facilities of any user to ascertain whether the purpose of this chapter 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 town, approval authority's, or EPA's access to the user's premises shall be a violation of this chapter. Unreasonable delays may constitute denial of access.
(C) Search warrants. If the town, 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 chapter, 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 chapter or any permit or order issued hereunder, or to protect the overall public health, safety and welfare of the community, then the town, approval authority, or EPA may seek issuance of a search warrant from the court having jurisdiction within the town.
(Ord. passed 12-3-2012)
(A) Information and data provided by an industrial user to the POTW Director pursuant to this chapter identifying the nature and frequency of a discharge, shall be available to the public without restriction. All other information which may be so submitted by an industrial user to the POTW Director in connection with any required reports shall also be available to the public unless the industrial user or other interested person specifically identifies the information as confidential upon submission and is able to demonstrate to the satisfaction of the POTW Director that the disclosure of such information or a particular part hereof to the general public would divulge methods or processes entitled to protection as trade secrets.
(B) Information provided by an industrial user to the POTW Director that is determined to be entitled to confidential treatment shall be made available upon written request to the Division of Water Quality or any state agency for uses related to the Pretreatment Program, the National Pollutant Discharge Elimination System (NPDES) Permit, collection system permit, stormwater permit, and/or non-discharge permit, and for uses related to judicial review or enforcement proceedings involving the person furnishing the report.
(C) Information and data received by the division or other state agency under § 53.08(B) above shall be subject to the processes set forth in G.S. § 143-215.3C.
(Ord. passed 12-3-2012)
(A) Administrative remedies.
(1) Notification of violation. Whenever the POTW Director finds that any industrial user has violated or is violating this chapter, 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 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.
(2) 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 § 53.09(A)(4).
(3) Show cause hearing.
(a) The POTW Director may order any industrial user who causes or is responsible for an unauthorized discharge, has violated this chapter 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 10 days before the hearing. Service may be made on any agent or officer of a corporation.
(b) The POTW Director shall review the evidence presented at the hearing and determine whether the proposed enforcement action is appropriate.
(4) Administrative orders. When the POTW Director finds that an industrial user has violated or continues to violate this chapter, 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:
(a) Immediately comply with all requirements;
(b) Comply in accordance with a compliance time schedule set forth in the order;
(c) Take appropriate remedial or preventive action in the event of a continuing or threatened violation;
(d) Disconnect unless adequate treatment facilities, devices or other related appurtenances are installed and properly operated within a specified time period.
(5) Emergency suspensions.
(a) 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 non-discharge permit.
(b) 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 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 individual. 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.
(6) Termination of permit or permission to discharge. The POTW Director may revoke a wastewater discharge permit or permission to discharge for good cause, including, but not limited to, the following reasons:
(a) Failure to accurately report the wastewater constituents and characteristics of his discharge;
(b) Failure to report significant changes in operations, or wastewater constituents and characteristics;
(c) Refusal of reasonable access to the user's premises for the purpose of inspection or monitoring; or
(d) Violation of conditions of the permit or permission to discharge, conditions of this chapter, or any applicable state and federal regulations.
(7) Noncompliant industrial users will be notified of the proposed termination of their wastewater permit and will be offered an opportunity to show cause under § 53.09(A) why the proposed action should not be taken.
(B) (1) Civil penalties. Any user who is found to have failed to comply with any provision of this chapter, or the orders, rules, regulations and permits issued hereunder, may assessed a civil penalty of up to $25,000 per day per violation.
(2) Penalties between $10,000 and $25,000 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 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 chapter, 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 5 years preceding the violation.
(3) In determining the amount of the civil penalty, the POTW Director shall consider the following:
(a) 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;
(b) The duration and gravity of the violation;
(c) The effect on ground or surface water quantity or quality or on air quality;
(d) The cost of rectifying the damage;
(e) The amount of money saved by noncompliance;
(f) Whether the violation was committed willfully or intentionally;
(g) The prior record of the violator in complying or failing to comply with the pretreatment program;
(h) The costs of enforcement to the town.
(i) Appeals of civil penalties assessed in accordance with this section shall be as provided in § 53.11.
(C) Other available remedies. Remedies, in addition to those previously mentioned in this chapter, and are available to the POTW Director who may use any single 1 or combination against a noncompliant user. Additional available remedies include, but are not limited to:
(1) 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. § 143-2l5.6B(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. Article 21, Chapter 143 (G.S. § 143-215.6B(i))).
(2) Injunctive relief. Whenever a user is in violation of the provisions of this chapter or an order or permit issued hereunder, the POTW Director, through the City 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.
(3) Water supply severance. Whenever an industrial user is in violation of the provisions of this chapter or an order or permit issued hereunder, water service to the industrial user may be severed and service will only recommence, at the user's expense, after it has satisfactorily demonstrated ability to comply.
(4) Public nuisances. Any violation of the prohibitions or effluent limitations of this chapter 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 chapter of the town governing such nuisances, including reimbursing the POTW for any costs incurred in removing, abating or remedying said nuisance.
(D) Remedies nonexclusive. The remedies provided for in this chapter 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 1 enforcement action against any noncompliant user.
(Ord. passed 12-3-2012)
At least annually, the POTW Director shall publish in a newspaper of general circulation that provides meaningful public notice within the jurisdiction(s) served by the POTW, a list of those industrial users which were found to be in significant noncompliance, also referred to as reportable noncompliance, in 15A NCAC 2H .0903(b)(34), with applicable pretreatment standards and requirements, during the previous 12 months.
(Ord. passed 12-3-2012)
Judicial review. An applicant whose permit is denied, or is granted subject to conditions he/she deems unacceptable, a permittee/user assessed a civil penalty under § 53.09(B), or 1 issued an administrative order under § 53.09(A) may seek judicial review of the order or decision by filing a written request for review by the Superior Count of Wilkes County within 30 days after receipt of notice by registered or certified mail of the order or decision, but not thereafter, along with a copy to the town. Within 30 days after receipt of the copy of the petition of judicial review, the Council or Board serving the town shall transmit to the reviewing court the original or a certified copy of the official record of their decision.
(Ord. passed 12-3-2012)
(A) Upset.
(1) An upset shall constitute an affirmative defense to an action brought for noncompliance with categorical pretreatment standards if the requirements of § 53.12(A)(2) below, are met.
(2) A user who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:
(a) An upset occurred and the user can identify the cause(s) of the upset;
(b) 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
(c) The user has submitted the following information to the POTW Director within 24 hours of becoming aware of the upset (if this information is provided orally, a written submission must be provided within 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.
(3) In any enforcement proceeding, the user seeking to establish the occurrence of an upset shall have the burden of proof.
(4) 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.
(5) 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.
(B) Prohibited discharge standards defense.
(1) A user shall have an affirmative defense to an enforcement action brought against it for noncompliance with the general prohibitions in § 53.03(A)(1) or the specific prohibitions in § 53.03(B)(2), (3), and (5) - (7) and (9) - (23) 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 pass through or interference and that either:
(2) 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
(3) 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.
(C) Bypass.
(1) A user may allow any bypass to occur which does not cause pretreatment standards or requirements to be violated, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provision of divisions (2) and (3) of this section.
(2) If a user knows in advance of the need for a bypass, it shall submit prior notice to the POTW Director, at least 10 days before the date of the bypass, if possible.
(3) A user shall submit oral notice to the POTW Director of an unanticipated bypass that exceeds applicable pretreatment standards within 24 hours from the time it becomes aware of the bypass. A written submission shall also be provided within 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 24 hours.
(4) Bypass is prohibited, and the POTW Director may take an enforcement action against a user for a bypass, unless:
(a) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;
(b) 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
(c) The user submitted notices as required under division (C)(2) of this section.
(5) The POTW Director may approve an anticipated bypass, after considering its adverse effects, if the POTW Director determines that it will meet the 3 conditions listed in division (C)(4) of this section.
