CHAPTER 25

INDUSTRIAL PRETREATMENT RULES AND REGULATIONS

OF THE

NEENAH‑MENASHA SEWERAGE COMMISSION

25.01 GENERAL PROVISIONS - PURPOSE AND POLICY

The purpose of these rules and regulations is to establish uniform requirements for Industrial Users of the Neenah‑Menasha Sewerage Commission's (NMSC) interceptors and Wastewater Treatment System to enable the Commission to protect its sewage transport and treatment facilities, its wastewater treatment process efficiency, its ability to continue land disposal of conformity with applicable local, State and Federal laws.

The policy of these rules and regulations is:

(1) To establish uniform requirements for direct and indirect contributors to the wastewater collection and treatment system owned and operated by NMSC and to enable NMSC to comply with applicable State and Federal laws including the General Pretreatment Regulations (40 CFR, Part 403).

(2) To prevent the introduction of pollutants into the NMSC's wastewater system which would:

(a) Interfere with the operation of the system.

(b) Cause the treatment plant to violate its WPDES Permit.

(d) Pass through the system, inadequately treated, into receiving waters or the atmosphere.

(e) Pose a health threat to sewer workers.

(f) Be otherwise incompatible with the system.

(3) To improve the opportunity to recycle and reclaim wastewaters and sludges from the system.

Accordingly, these rules and regulations are promulgated and ordained by the NMSC to provide for the regulation of discharges into the Commission's wastewater system through issuance by the Commission of discharge permits to Industrial Users.

(3) Contracting Municipality: Shall mean any of the Wisconsin municipalities enumerated in Chapter 2, section 2.01 L, herein.

(4) pH Test Procedures: Shall mean those pH neutralization test procedures which are set forth in detail in this chapter.

(b) Obtaining PH Variance Authorization. The NMSC may approve and authorize a variance to the upper pH limit set forth under section 3.01, C, hereof, regarding the effluent proposed to be discharged to the Wastewater Treatment System by an Industrial Discharger, provided the following conditions are met:

(1) A written request for such variance, indicating the extent of pH variance requested and the specific reason for such request, is made to the NMSC.

(2) The Contracting Municipality within which nonconforming effluent is proposed to be discharged approves such nonconforming discharge in writing.

(3) The Industrial Discharger adequately demonstrates and establishes to the satisfaction of NMSC by the pH neutralization test procedures described below that the MILLIEQUIVALENTS of acid required to lower the maximum pH of the discharge at maximum effluent flow conditions to pH 10 is less than the MILLIEQUIVALENTS of caustic required to raise the pH of the wastewater in the receiving sewer at minimum flow conditions to pH 10.

(4) That any pH variance authorized by the NMSC shall be conditioned upon amendment and modification of the Industrial Discharger's wastewater permit to incorporate the variance and any limitations or conditions to which the variance has been made subject by the NMSC. If the Industrial Discharger does not hold a permit, the Industrial Discharger shall be required to obtain a discharge permit from the NMSC before any pH variance may be exercised.

(5) Any pH variance granted by the NMSC shall be limited to the life of the permit of such Industrial Discharger. At the time of permit renewal, the NMSC, at its sole discretion, may incorporate the pH variance into the renewed permit or may require the Industrial Discharger to submit a new variance request.

(c) Termination of pH Variance Authorization. The NMSC may terminate pH variance authorization to any Industrial Discharger, at the sole discretion of the Commission, should the Commission determine that discharge under such variance is detrimental to the Wastewater Treatment System in any way. Termination of pH variance authority shall become effective upon 90‑day written notice by the NMSC to the Industrial Discharger, made by registered U. S. mail, or equivalent, return receipt requested. Following such notice the Industrial Discharger shall: (i) report the actions the Industrial Discharger intends to take to insure that its future effluent discharge is not at variance with the upper pH limit established in subsection 3.01r C, herein; (ii) furnish the NMSC with a compliance schedule implementing such proposed action. Provided such action and compliance schedule are approved by the NMSC, the Industrial Discharger may continue pH variance discharge pursuant to the approved schedule. Failing approval by NMSC of either the proposed compliance action or schedule, all variable discharge by the Industrial Discharger shall cease upon the expiration of 90 days from its receipt of the termination notice.

(d) Neutralization Test Procedures. As part of the pH variance authority application to NMSC by an Industrial Discharger seeking pH variance authority, the following pH test procedures shall be performed by a commercial testing laboratory certified by the State of Wisconsin, the results of which shall be submitted in writing to NMSC as an attachment to the application for pH variance authority:

(1) Determination of Applying Industrial Discharger's Maximum Discharge pH. The Industrial Discharger applicant shall have a commercial laboratory continuously monitor the Industrial Discharger's flow and pH for a consecutive two-week period at the place or places of discharge concerning which pH variance is requested. The daily maximum and average pH value and flows (GPM) shall be reported to NMSC.

(2) Grab Sample. The Industrial Discharger applicant shall cause a commercial laboratory to collect a grab sample of its wastewater when the maximum pH value is achieved. The following test shall be conducted of such sample.

(a) A 100 milliliter aliquot of sample shall be titrated with 0.25N Hydrochloric acid to pH 10.

(b) The milliequivalents (MEQ) of acid to lower the maximum discharge flow to pH 10 shall be calculated as follows: (MEQ of acid = mls of acid for 100 ml aliquot x acid normality x 37.5 x maximum flow [gallons per minute])

(3) Upstream Monitoring. The Industrial Discharger applicant shall cause such commercial laboratory to monitor the receiving sewer flow immediately upstream of the applicant's discharge point(s) for a two-week period. Flow data (GPM) to be reported to NMSC shall include daily minimum, daily maximum and average flows.

(4) Upstream Grab Sample. Such commercial laboratory shall collect a grab sample of wastewater from the receiving sewer immediately upstream of applicant's discharge point(s). The following test shall be conducted of the sample:

(a) A 100 milliliter aliquot of sample shall be titrated with 0.25N Sodium Hydroxide to pH 10.

(b) The milliequivalents (MEQ) of caustic to raise the minimum sewerage flow in the receiving sewer to pH 10 shall be calculated as follows: (MEQ) of acid = mls of NaOH for 100 ml aliquot x NaOH normality x 37.5 x minimum flow [gallons per minute]

(e) NMSC Industrial User Contracting Requirements. In accordance with the September 28, 1982 Ordinance‑Contract, (adopted by five local municipalities to jointly reorganize the Neenah‑Menasha Sewerage Commission), any industrial user shall become a Contracting Industrial User if its annual average flow exceeds 640,000 gallons per day, or its annual average five day biochemical oxygen demand (BOD) exceeds 898 pounds per day, or its annual average suspended solids (SS) exceeds 795 pounds per day. A Contracting Industrial User must negotiate a commitment with the NMSC, in contract form, regarding use by such industry of the NMSC sewerage system and regarding payment by such industry of costs in accordance with section 507 of the Ordinance‑Contract.

(4) Dilution. The discharger shall not utilize any technique which has as its purpose or likely result the dilution of its effluent, including but not limited to, increasing the use of potable or process water, mixing separate wastestreams, collecting and temporarily containing a wastestream for later discharge, or, in any way, attempting to dilute an effluent as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in this ordinance. NMSC may impose mass limitations on discharger if, in the opinion of NMSC, discharger may be using dilution to meet applicable pretreatment standards or requirements, or in such cases where imposition of mass limitations is deemed appropriate by NMSC.

25.07 ACCIDENTAL DISCHARGES

(1) Protection From Accidental Discharges. Each Discharger shall carefully survey its facilities, no less than annually, and shall provide, where reasonably necessary, adequate protection against accidental discharge or discharge of prohibited or regulated materials or substances established by these rules and regulations. Where necessary, facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the Discharger's cost and expense. The NMSC, at its discretion, when it determines such to be necessary, may mandate the construction and maintenance of such facilities and operating procedures by a Discharger when it neglects or refuses to do so. Detailed plans and specifications showing the facilities and operating procedures proposed to provide needed protection, together with a proposed compliance schedule, shall be submitted to the Commission for its review, and shall be approved by the Commission before construction of the facility may begin. A Discharger shall complete its plan and compliance schedule and submit them to the Commission within ninety (90) days of written notification of need from the Commission. The Commission shall have sixty (60) days from receipt of same to review and comment on the plan and the compliance schedule and to mandate any changes in either. Provided the Discharger faithfully observes the foregoing provisions, including the compliance schedule as approved by the Commission, it may at all times, continue its discharge to the sewer system, subject to these rules and regulations. Review and approval of such plans and operating procedures by the Commission and construction of such facilities by Discharger shall not relieve it of the responsibility to further modify its facility as necessary to meet the requirements of these rules and regulations.

(2) Notification of Accidental Discharge. Each Discharger shall immediately notify the Commission upon the occurrence of any Slugload, or any accidental discharge of substances prohibited by these rules and regulations. Such notification shall include information regarding the location of the discharge, the date and time thereof, the type of waste, the concentration and volume, and all corrective actions taken. Any Discharger who discharges a Slugload of prohibited materials shall be liable for any expense, loss or damage to the POTW resulting therefrom, in addition to payment of any fines imposed by the Commission (or upon the Commission) as the result thereof under local, State, or Federal law. Within five (5) days of the date of occurrence, the Discharger shall submit a detailed written report describing the cause(s) of the discharge and the measures to be taken by the Discharger to prevent similar future occurrences.

(3) Signs. Prominent signs shall be permanently posted and maintained in multiple conspicuous places on Discharger's premises, advising its employees to immediately telephone the Commission in the event of occurrence of a Slugload or accidental discharge. No less frequently than annually, every Discharger shall instruct all of its employees who are in a position to cause or discover a Slugload or accidental discharge of Discharger's immediate notification obligation.

25.11 REPORTING REQUIREMENTS FOR PERMITTEE

(1) Reporting Requirements. All Industrial Dischargers subject to Categorical Pretreatment Standards, at a minimum, shall comply with the reporting requirements contained in 40 CFR, Part 403.12, including, but not limited to those subparts entitled Baseline Monitoring Reports, Compliance Date Reports, and Periodic Compliance Reports. All reports required of an Industrial Discharger by this Ordinance shall be signed by an authorized representative of the Discharger and accompanied by a chain of custody record for any laboratory data reported.

(2) Compliance Date Report. Within ninety (90) days following the date for final compliance by the Discharger with applicable Pretreatment standards set forth in these rules and regulations, or within ninety (90) days following commencement of the introduction of wastewater into the POTW by a new Discharger, such Discharger subject to these rules and regulations all submit to the Commission a report indicating the nature and concentration of all prohibited or regulated substances contained in its discharge, and the average and maximum daily flow in gallons. The report shall state whether the applicable Pretreatment standards or requirements are being met on a consistent basis and, if not, what additional operation and maintenance and/or Pretreatment is necessary to bring the Discharger into compliance with the applicable Pretreatment standards or requirements. This statement shall be signed by an authorized representative of the Discharger, and certified by a registered professional qualified to do so.

(3) Periodic Compliance Reports.

(a) Any Discharger subject to a Pretreatment standard or Pretreatment requirements, after the compliance date of such Pretreatment standard, or, in the case of a new Discharger, after commencement of the discharge to the POTW, shall submit to the Commission during the months of June and December each year, unless required more frequently by the Commission, a report indicating the nature and concentration of prohibited or regulated effluent substances which are limited by the Pretreatment standards hereof. In addition, this report shall include a record of all measured or estimated average and maximum daily flows previously reported under Section 5.02 B. The Commission, for good cause shown considering such factors as local high or low flow rates, holidays, budget cycles, or other extenuating factors, may authorize the submission of said reports in months other than those specified above.

(b) Reports of permittees shall contain the full results of all sampling and analysis of the discharge, including the flow, the nature and concentration thereof, and production and mass when required by the Commission. The frequency of monitoring by the Discharger shall be as prescribed in the applicable Categorical Pretreatment Standards. Where such Standards do not specify the frequency of monitoring, the Discharger shall perform the required monitoring as specified in the Commission's Pretreatment Program Implementation Procedures Manual. All analyses shall be performed in accordance with 40 CFR, Part 136 and amendments thereto (Comment: Where 40 CFR, Part 136 does not include a sampling or analytical technique for the pollutant in question sampling and analysis shall be performed in accordance with the procedures set forth in the EPA publication, Sampling and Analysis Procedures for Screening of Industrial Effluent for Priority Pollutants, April 1977, and amendments thereto, or with any other sampling and analytical procedures approved by the Administrator of the U. S. EPA). A minimum of four (4) grab samples must be used for pH, cyanide, total phenols, oil and grease, sulfide, and volatile organics. For all other pollutants, 24‑hour composite samples must be obtained through flow‑proportional composite sampling techniques where feasible. The NMSC may waive flow-proportional composite sampling for any industrial user that demonstrates that flow‑proportional sampling is infeasible. In such cases, samples may be obtained through time-proportional composite sampling techniques or through a minimum of four (4) grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged. All sampling shall be done during days when industrial discharges are occurring at normal to maximum levels.

(c) If the results of the discharger's wastewater analysis indicate a violation has occurred, the discharger shall notify the NMSC within 24 hours of becoming aware of the violation and repeat the sampling and pollutant analysis and submit, in writing, the results of this repeat analysis within 30 days after becoming aware of the violation.

(4) Notification of Hazardous Waste in Discharge.

(a) The Discharger shall notify the NMSC, the EPA Region V Waste Management Division Director, and the DNR Bureau of Solid and Hazardous Wastes in writing of any discharge by Discharger to the NMSC system 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 Discharger discharges more than 100 kilograms of such waste per calendar month to the NMSC, the notification shall also contain the following information to the extent such information is known and readily available to the Discharger: an identification of the hazardous constituents contained in the wastes, an estimation of the mass and concentration of such constituents in the wastestream discharged during that calendar month, and an estimation of the mass of constituents in the wastestream expected to be discharged during the following twelve months. A Discharger shall provide such notification no later than 180 days after the discharge of the listed or characteristic hazardous waste. Any notification under this paragraph need be submitted only once for each hazardous waste discharged. However, notification of changed discharges must be submitted under 40 CFR 403.12(j). The notification requirements in this section do not apply to pollutants already reported under the self‑monitoring requirements of 40 CFR 403.12(b), (d), and (e).

(b) Dischargers are exempt from the requirements of this section during a calendar month in which they discharge no more than fifteen kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e). Discharge of more than fifteen kilograms of non‑acute 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.

(c) Subsequent months during which the Discharger discharges more than such quantities of any hazardous waste do not require additional notification.

(d) In the case of any new regulations under Section 3001 of RCRA identifying additional characteristics of hazardous waste or listing any additional substance as a hazardous waste, the Discharger must notify the NMSC, the EPA Region V Waste Management Division Director, and the DNR Bureau of Solid and Hazardous Wastes of the discharge of such substance within 90 days of the effective date of such regulations.

(e) In the case of any notification made under this section, the Discharger 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.

25.12 PRETREATMENT FACILITIES

Industrial Dischargers shall provide necessary wastewater Pretreatment as required to comply with these rules and regulations and shall achieve compliance with all Categorical Pretreatment Standards or Pretreatment requirements within the limitations as specified by the federal Categorical Pretreatment Regulations. Any facilities required to pretreat wastewater to a level acceptable to the Commission shall be provided, operated and maintained efficiently and in good operating condition at the Industrial Discharger's sole expense.

25.13 SUBMISSION OF PLANS

Where Pretreatment or equalization of wastewater flows to discharge into any part of the wastewater treatment system is required, plans, specifications, operating procedures, and other pertinent data or information relating to such Pretreatment flow-control facilities shall first be submitted by the Industrial Discharger to the Commission for review, comment, revision and/or approval. The review of such plans and operating procedure will in no way relieve the Industrial Discharger from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the commission under the provisions of these rules and regulations. Any subsequent changes to such Pretreatment or flow‑control facilities or methods of operation shall be reported to and be approved by the Commission prior to the Industrial Dischargers initiation of the changes.

25.14 MONITORING FACILITIES

At the Commission's discretion and direction, a Discharger shall provide and operate at its own expense; a monitoring facility to allow inspection, sampling and flow measurements of each sewer discharge to the public sewer and POTW. Each monitoring facility shall be situated on the Discharger's premises, unless to do so would be impractical or cause undue hardship to the Discharger, in which event the Commission may allow the facility to be constructed in the public street or sidewalk area provided it is so located that it will not be obstructed by landscaping or parked vehicles. There shall be ample room in or near each monitoring facility to allow accurate sampling and preparation of samples for analysis. The facility, sampling, and measurement equipment shall be maintained at all times in safe and proper operating condition, at the expense of the Discharger.

All monitoring facilities shall be constructed and maintained in accordance with applicable local construction standards and specifications.

25.15 INSPECTION AND SAMPLING

The Commission, Wisconsin DNR and US EPA may at any time inspect the monitoring facilities of any Discharger to determine its Compliance with these rules and regulations. The Discharger shall allow the Commission or its representatives to enter upon Premises of the Discharger for the purposes of inspection, sampling, or records examination. The Commission shall have the right to set up on the Discharger's property, at any time, such devices as are necessary to independently conduct sampling, inspection, compliance monitoring and/or metering operations. Sampling of industrial wastewater for the purpose of compliance determinations with respect to Chapter 3 prohibitions and limitations shall be done at such intervals as the Commission may designate. However, it is the intention of the Commission to conduct compliance sampling or cause such sampling to be conducted, at least once every year, for all Industrial Dischargers whose wastewater contribution may significantly impact the Commission's wastewater treatment system.

25.16 CONFIDENTIAL INFORMATION

Information and data furnished to the Commission with respect to the nature and frequency of discharge shall be available to the public or any governmental agency without restriction unless the Discharger specifically requests and is able demonstrate to the reasonable satisfaction of the Commission that the release of such information would divulge information, processes or methods of production entitled to protection as trade secrets or proprietary information of the Discharger. When requested by a Discharger furnishing a report, the portions of a report which may disclose trade secrets or secret processes shall not be made available for inspection by the public; 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 Discharger furnishing the report. Wastewater constituents and characteristics shall not be recognized as confidential information. In no event shall any information be withheld from the public that is by definition a public record as defined in section 19.34, Wis. State Stats., as amended.

25.17 EMERGENCY SUSPENSION OF WASTEWATER DISCHARGE PERMIT AND SUSPENSION OF SERVICE

For good cause the Commission may suspend and cut‑off the wastewater treatment service and the Wastewater Discharge Permit of any Discharger when the Commission determines that such Discharger's actual or threatened conduct or discharge presents or threatens: (i) imminent substantial danger to the health or welfare of any person; (ii) imminent substantial danger to the environment; (iii) adverse Interference with the operation of the Neenah-Menasha Sewerage Commission sewage treatment plant or facilities; (iv) violation of any Pretreatment limits imposed by these rules and regulations; (v) violation of any of the provision s of the Discharger's Wastewater Discharge Permit issued pursuant to these rules and regulations; (vi) violation of the Commission WPDES or State discharge permit; or (vii) the Commission determines any of the reasons exist set forth in Section 6.02. Any Discharger notified by the NMSC of suspension of its wastewater treatment service and suspension of its Wastewater Discharge Permit, and the cause therefore, shall immediately cease or eliminate its adverse discharge, or correct its noncompliant conduct, within a time period determined by the Commission and specified in the notice of suspension. Such a notice shall be deemed an order issued by the NMSC, as the term "order" is employed in this Chapter. In the Commission's discretion, prior to hearing, such a suspension order may be summarily implemented by an immediate service cut‑off, if reasonably required to prevent or halt an emergency due to imminent danger to the public health or welfare, or imminent danger to the environment, or imminent danger of POTW Interference, created by the affected Discharger's actual or threatened discharge or conduct. The Commission may reinstate the Wastewater Discharge Permit and resume wastewater treatment service to the Discharger, and terminate any judicial proceedings, upon due and satisfactory proof by the Discharger of its full elimination of any noncomplying conduct or discharge and of any conditions creating a threat of imminent danger, including, at the Commission's discretion, posting with the Commission and maintenance by the Discharger of a performance bond or a liability insurance policy in a form and amount determined by the NMSC.

25.18 GROUNDS FOR REVOCATION, TERMINATION OR REISSUANCE REFUSAL OF PERMIT

The Commission may revoke, terminate or refuse to reissue or extend the Wastewater Discharge Permit of any Discharger who: (i) has failed to properly collect, maintain or retain any information or records required hereunder or by any permit issued hereunder; (ii) has falsified any information or records which it is required to collect, maintain, retain or submit to NMSC in accordance with either this ordinance or any permit issued hereunder; (iii) has failed to timely, accurately and/or fully make any report, notice or schedule required by this ordinance or any permit issued hereunder, including, but not limited to, reports pertaining to the wastewater constituents and characteristics of its discharge; or (iv) has failed to timely report significant changes in its wastewater constituents or characteristics; or (v) refuses NMSC or its agents reasonable access to the Discharger's premises for the purpose of inspecting, monitoring and determining Discharger's compliance with its permit and this ordinance; or (vi) violates the conditions or provisions of its Wastewater Discharge Permit; or (vii) violates these rules and regulations, including but not limited to, failure to pay fines, to pay sewer charges or to timely meet compliance schedules; or (viii) violates any NMSC or judicial order entered with respect thereto; or (ix) when changed circumstances require the NMSC to effect temporary or permanent reduction or elimination of a permitted discharge.

25.19 NOTIFICATION OF VIOLATION AND SUSPENSION OR REVOCATION

When the Commission ascertains that any Discharger has engaged in, or threatens to engage in, conduct which justifies NMSC suspension of wastewater treatment service and suspension, revocation, termination or refusal to reissue or extend its Wastewater Discharge Permit, pursuant to either Section 6.01 or 6.02 hereof, the Commission shall serve or cause to be served nature of the alleged actual or threatened violation; (ii) cites the legal authority of the NMSC to terminate service and suspend or revoke Discharger's Wastewater Discharge Permit; (iii) describes the method for terminating treatment service; and (iv) specifies the date and time of service termination. Such a notice shall be deemed an order issued by the NMSC, as the term "order" is employed in this Chapter. Within a time period specified in such notice, the Discharger shall respond in writing to the NMSC, advising of its position with respect to the matters set forth in the notice. Thereafter, the parties or their designees appointed in writing shall meet to discuss the actual or threatened violations and, where necessary, to establish a plan for satisfactory correction thereof. If the matter is not resolved at such meeting, or if the Discharger refuses to meet, and if a hearing has not previously been scheduled by the NMSC, the NMSC may schedule a show cause hearing or the Discharger may request a show cause hearing pursuant to the provisions of section 6.05.

25.31 BYPASS PROVISIONS

An Industrial User may allow a Bypass to occur which does not cause Pretreatment Standards or Requirements to be violated, but only if it is also done in furtherance of essential maintenance by Discharger to assure efficient operation. Such a Bypass is subject to the provisions of paragraphs A. and B. of this section.

(1) Notice.

(a) If an Industrial User knows in advance of the need a Bypass, it shall submit prior written notice to the NMSC, if possible at least ten days before the date of intended bypass.

(b) An Industrial User shall submit oral notice of an unanticipated Bypass that exceeds applicable Pretreatment Standards to the NMSC within 24 hours from the time the Industrial User becomes aware of the Bypass. A written submission shall also be provided within 5 days of the time the Industrial 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 or prevent recurrence of a Bypass. The NMSC may waive the written report on a case‑by‑case basis if an oral report has been received within 24 hours.

(2) Prohibition of Bypass.

(a) Bypass is prohibited and the NMSC may take enforcement action against an Industrial User for a Bypass, unless:

(1) The Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage, as defined in section 2.01.

(2) There were no feasible alternatives to the Bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or Discharger's performance of maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back‑up equipment could have been installed in the exercise of reasonable engineering judgment to prevent a Bypass which occurred during normal periods of equipment downtime or preventative maintenance.

(3) The Industrial User has submitted notices as required under paragraph A of this section.

(b) The NMSC may approve an anticipated bypass, after considering its adverse effects, if the NMSC determines that it will meet the three conditions listed in paragraph B. 1. of this section.

25.32 CIVIL PENALTIES

Any Discharger who is determined by a court of competent jurisdiction: (i) to have violated an order of the Commission; or (ii) to have failed to comply with any provision of these rules and regulations, or any permit issued hereunder, upon conviction shall be subject to imposition of a civil penalty of not less than One Hundred Dollars ($100.00), nor more than Five Thousand Dollars ($5,000.00), for each day such violation exists.
