[Adopted 10-7-2002]
A. 
This article sets forth uniform requirements for direct and indirect discharges of pollutants from nondomestic sources into the wastewater collection and treatment system for the Town of Middletown, Delaware, and enables the Town to comply with all applicable state and federal laws, including the Clean Water Act (33 U.S.C. § 1251), and the General Pretreatment Regulations (40 CFR Part 403). The objectives of this article are:
(1) 
To prevent the introduction of pollutants into the municipal wastewater system which will interfere with the operation of the system;
(2) 
To prevent the introduction of pollutants into the municipal wastewater system which will pass through the system, inadequately treated, into receiving soils, the atmosphere, or otherwise be incompatible with the system and/or treated effluent disposal methods;
(3) 
To ensure that the quality of the wastewater treatment plant sludge is maintained at a level which would allow complete and adequate stabilization;
(4) 
To protect municipal personnel who may come into contact with sewage, sludge, and effluent in the course of their employment as well as the general public;
(5) 
To preserve the hydraulic capacity of the municipal system;
(6) 
To improve the opportunity to recycle and reclaim wastewater from the system;
(7) 
To provide for equitable distribution of the cost of operation, maintenance and improvement of the municipal wastewater system; and
(8) 
To ensure the Town complies with its spray irrigation permit conditions, disposal requirements, and any other federal or state laws, which the municipal wastewater system is subject to.
B. 
This article provides for the regulation of direct and indirect discharges to the municipal wastewater collection system through the issuance of permits to certain nondomestic users and through enforcement of general requirements for other users, authorizes monitoring and enforcement activities, establishes administrative review procedures, requires user reporting, and provides for the setting of fees for the equitable distribution of costs resulting from the program established herein.
C. 
This article shall apply to the Town and persons outside of the Town who, by contract with the Town, are included as users of the municipal wastewater system. Except as otherwise provided herein, the Superintendent of the municipal wastewater system or his designees shall administer, implement, and enforce the provisions of this article.

B. 
Categorical regulated industrial discharge. Any industrial discharger required under federal law to meet national categorical pretreatment standards for any pollutant shall meet these standards in its discharge, provided that such standards are more stringent than the local standards established in this section for the pollutant. Where categorical standards are less stringent than the local standards, the local standards shall apply.
C. 
The concentrations apply at the point where the industrial waste is discharged into the municipal wastewater system. All concentrations for metallic substances are for "total" metal. At his discretion, the Superintendent may impose mass limitations in addition to or in place of the concentration based limitations above. Compliance with all parameters may be determined with a single grab sample.
The Town reserves the right to establish, by ordinance or in wastewater permits, more stringent limitations or requirements on discharges to the municipal wastewater system if deemed necessary to comply with the objectives presented in § 136-18 of this article or the general and specific prohibitions in § 136-21 of this article.
The Town reserves the right to enter into special agreements with users setting out special terms under which the industrial user may discharge to the system. In no case will a special agreement waive compliance with a pretreatment standard. However, the industrial user may request a net gross adjustment to a categorical standard in accordance with 40 CFR 403.15. Industrial users may also request a variance from the categorical pretreatment standards from the U.S. EPA. Such a request will be approved only if the user can prove the factors relating to its discharge are fundamentally different from the factors considered by U.S. EPA when establishing that pretreatment standard. An industrial user requesting a fundamentally different factor variance must comply with the procedural and substantive provisions in 40 CFR 403.13.
No user shall ever increase the use of process water or in any way attempt to dilute a discharge as a partial or complete substitution for adequate treatment to achieve compliance with a discharge limitation unless expressly authorized by an applicable pretreatment standard, or in any other pollutant-specific limitation set by the Town.
Industrial users shall provide necessary wastewater treatment as required to comply with this article and shall achieve compliance with all categorical pretreatment standards, local limits and prohibitions set out in §§ 136-21 through 136-27 above, with limitations specified by the Superintendent. Any facilities required to pretreat wastewater to a level acceptable to the Town shall be provided, operated, and maintained at the industrial user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the Town for review, and shall be acceptable to the Town 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 acceptable discharge to the Town under the provisions of this article.
Whenever deemed necessary, the Superintendent may require the industrial user to restrict the industrial user's discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage waste streams from industrial waste streams, and such other conditions as may be necessary to protect the municipal wastewater system and determine the industrial user's compliance with the requirements of this article.
A. 
Each person discharging into the municipal wastewater system greater than 100,000 gallons per day or greater than 5% of the average daily flow in the system, whichever is lesser, shall install and maintain, on his property at his expense, a suitable storage and flow control facility to ensure equalization of flow over a twenty-four-hour period. The facility shall have a capacity for at least 50% of the daily discharge volume and shall be equipped with alarms and a rate of discharge controller, the regulation of which shall be directed by the Superintendent. A wastewater permit may be issued solely for flow equalization.
B. 
Grease, oil, and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of wastewater containing excessive amounts of grease, flammable substances, sand, or other harmful substances; except that such interceptors shall not be required for residential users. All interception units shall be of a type and capacity approved by the Superintendent and shall be so located to be easily accessible for cleaning and inspection.
C. 
Industrial users with a potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.
A. 
Industrial users shall provide protection from accidental discharge of materials which may interfere with the municipal wastewater system by developing spill prevention plans. Facilities necessary to implement these plans shall be provided and maintained at the owner or industrial user's expense. Spill prevention plans, including the facility and operating procedure, shall be approved by the Town before implementation of the plan.
B. 
Industrial users that store hazardous substances shall not contribute to the municipal wastewater system after the effective date of this article unless a spill prevention plan has been approved by the Town. Approval of such plans shall not relieve the industrial user from complying with all other laws and regulations governing the use, storage, and transportation of hazardous substances.
Any person who shall occupy the industrial user's premises as a tenant under any rental or lease agreement shall be jointly and severally responsible for compliance with the provisions of this article in the same manner as the owner.
All new domestic wastewaters from restrooms, showers, and drinking fountains shall be kept separate from all industrial wastewaters until the industrial wastewaters have passed through the required treatment system and the industrial user's monitoring facility. When directed to do so by the Superintendent, industrial users must separate existing domestic wastewaters from industrial waste streams.
A. 
Septic tank waste (septet) will be accepted into the municipal wastewater system at a designated receiving location, and at such times as are established by the Superintendent, provided such wastes do not contain toxic or hazardous pollutants, and provided such discharge does not violate any other requirements established by the Town. Permits for individual vehicles to use such locations shall be issued by the Superintendent.
B. 
The discharge of industrial wastes as industrial septet requires prior approval and a wastewater permit from the Town. The Superintendent shall have authority to prohibit such wastes, if such disposal would interfere with treatment plant operations. Waste haulers are subject to all other sections of this article.
C. 
Fees for dumping septet will be established as part of the user fee system as authorized in § 136-84.
No person shall maliciously, willfully, or negligently break, damage, destroy, uncover, deface, tamper with, or prevent access to any structure, appurtenance or equipment, or other part of the municipal wastewater system. Any person found in violation of this requirement shall be subject to the sanctions set out in §§ 136-74 through 136-76 below.
When requested by the Superintendent, all industrial users must submit information on the nature and characteristics of their wastewater by completing a wastewater survey prior to commencing their discharge. The Superintendent is authorized to prepare a form for this purpose and may periodically require industrial users to update the survey. Failure to complete this survey shall be grounds for terminating service to the industrial user and shall be considered a violation of the Ordinance.
A. 
It shall be unlawful for significant industrial users to discharge wastewater into the Town's sanitary sewer system without first obtaining a wastewater permit from the Superintendent. Any violation of the terms and conditions of a wastewater permit shall be deemed a violation of this article and subjects the industrial user to sanctions set out in §§ 136-66 through 136-81. Obtaining a wastewater permit does not relieve a permittee from its obligation of other permits required by Federal, State, or local law.
B. 
The Superintendent may require other industrial users, including liquid waste haulers, to obtain wastewater permits as necessary to carry out the purpose of this chapter.
Any significant industrial user which discharges industrial waste into the municipal wastewater system prior to the effective date of this article, and who wishes to continue such discharge in the future, shall, within 90 days after said date, apply to the Town for a wastewater permit in accordance with § 136-40 below, and shall not cause or allow to cause a discharge to the system to continue after 180 days of the effective date of this article in accordance with a permit issued by the Superintendent.
Any significant industrial user proposing to begin or recommence discharging industrial wastes into the municipal wastewater system must obtain a wastewater permit prior to beginning or recommencing such discharge. An application for this permit must be filed at least 90 days prior to the anticipated start date.
Any existing significant industrial user located beyond the Town limits shall submit a permit application in accordance with § 136-40 below, within 90 days of the effective date of this article. New significant industrial users located beyond the Town limits shall submit such applications to the Superintendent 90 days prior to any proposed discharge into the municipal system. Upon review of such applications, the Superintendent may enter into a contract with the industrial user which requires the industrial user to subject itself to and abide by this chapter, including all permitting, compliance monitoring, reporting, and enforcement provisions herein. Alternatively, the Superintendent may enter into an agreement with the neighboring jurisdiction in which the significant industrial user is located to provide for the implementation and enforcement of the pretreatment program and requirements against said user.
In order to be considered for a wastewater permit, all industrial users required to have a permit must submit the following information on an application form developed by the Superintendent.
A. 
Name, mailing address, and location (if different from mailing address). Name of primary contact person, secondary contact person, and alternate contact person. (Contact person will be person designated to communicate with Superintendent on matters contained in this article.)
B.

For industrial users subject to equivalent mass and concentration limits established in accordance with the procedures in 40 CFR 403.6(c), this report shall contain a reasonable measure of the users long-term production rate. For all other industrial users subject to categorical pretreatment standards expressed in terms of allowable pollutant discharge per unit of production (or other measure of operation), this report shall include the user's actual production during appropriate sampling period. All compliance reports must be signed and certified in accordance with § 136-41.
All significant industrial users subject to a pretreatment standard shall, at a frequency determined by the Superintendent, but in no case less than twice per year, submit a report indicating the nature and concentration of pollutants in the discharge which are limited by such pretreatment standards and the measure of estimated average and maximum daily flows for the reporting period. All periodic compliance reports must be signed and certified in accordance with § 136-41.
A. 
All wastewater samples must be representative of the industrial user's discharge. Wastewater monitoring and flow measurement facilities shall be properly operated, kept clean, and maintained in good working order at all times. The failure of an industrial user to keep its monitoring facility in good working order shall not be grounds for the industrial user to claim that sample results are unrepresentative of this discharge.

This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user.
C. 
Within five days following an accidental discharge, the user shall, unless waived by the Superintendent, submit a detailed written report describing the cause(s) of the discharge and measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or liability which may be incurred as a result of damage to the system, natural resources, or any other damages to person or property nor shall such notification relieve the user of any fines, civil penalties, or other liability which may be imposed by this article.
D. 
Failure to notify the Town of potential problem discharges shall be deemed a separate violation of this article.
E. 
A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees who to call in the event of a discharge described in Subsection B, above. Employers shall ensure that all employees who may cause or suffer such a discharge to occur are advised of the emergency notification procedure.
All industrial users not subject to categorical pretreatment standards and who are not required to obtain a wastewater permit shall provide appropriate reports to the Town as the Superintendent may require.
A.

The facility's sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the industrial user at the industrial user's expense. All devices used to measure wastewater flow and quality shall be calibrated periodically to ensure their accuracy.
D. 
Any temporary or permanent obstruction to safe and easy access to the industrial facility to be inspected and/or sampled shall be promptly removed by the industrial user at the written or verbal request of the Superintendent and shall not be replaced. The cost of clearing such access shall be borne by the industrial user.
E. 
Any unreasonable delays (greater than 15 minutes) in allowing the Town personnel access to the industrial user's premises shall be a violation of this article.
If the Superintendent has been refused access to a building, structure or property, or any part thereof, and if the Superintendent has probable cause to believe that there has been a violation of this article or that there is a need to inspect as part of a routine inspection program of the Town designed to protect the overall public health, safety and welfare of the community, then, upon application by the Town Attorney, the Municipal Court Judge of the Town shall issue a search and/or seizure warrant describing therein the specific location subject to the warrant. The warrant shall specify what, if anything, may be searched and/or seized on the property described. Such warrant shall be served at reasonable hours by the Superintendent in the company of a uniformed police officer of the county. In the event of an emergency affecting public health and safety, or if the industrial user consents, inspections shall be made without the issuance of a warrant.
A. 
Information and data on an industrial user obtained from reports, questionnaires, permit applications, permits, and monitoring programs, and from Town inspection and sampling activities shall be available to the public without restriction unless the industrial user specifically requests and is able to demonstrate to the satisfaction of the Town that release of such information would divulge information, processes or methods of production entitled to protection as trade secrets under applicable state law.
B. 
Wastewater constituents and characteristics and other "effluent data," defined by 40 CFR 2.302, will not be recognized as confidential information and will be available to the public without restriction.
C. 
When requested and demonstrated by the industrial user furnishing a report that such information shall be held confidential, the portions of a report which might disclose trade secrets or special processes shall not be made available for inspection by the public, but shall be made available immediately, upon request, to governmental agencies for uses related to this article and in enforcement proceedings involving the person furnishing the report.
The Town shall annually publish, in the largest daily newspaper circulated in the area where the municipal wastewater system is located, a list of industrial users which, during the previous 12 months, were in significant noncompliance with applicable pretreatment standards and compliance. The term "significant noncompliance" shall mean:
A. 
Chronic violations of wastewater discharge limits in which 66% or more of all of the measurements taken during a six-month period exceed the permit limit for the same pollutant parameter.
B. 
Technical review criteria (TRC). Violations in which 33% or more of the measurements for a pollutant parameter taken during a six-month period equal or exceed the product of the permit limit multiplied by the applicable TRC. (TRC equals 1.4 for BOD, TSS, fats, oils, and grease, and 1.2 for all other pollutants except pH.)
C. 
Any other violation of a pretreatment effluent limit that the control authority determined has caused, alone or in combination with other discharges, interference or pass through.
D. 
Any discharge or pollutant that has caused imminent endangerment to human health, welfare or the environment, or has resulted in the POTW's exercise of its emergency authority to halt or prevent such a discharge.
E. 
Failure to meet, within 90 days after a schedule date, a compliance schedule milestone contained in the permit or enforcement order for starting construction, completing construction, or attaining final compliance.

G. 
Failure to accurately report noncompliance.
H. 
Any other violation or group of violations that the control authority determines will adversely affect the operation or implementation of the local pretreatment program.
Whenever the Superintendent finds that any industrial user has violated, or is in violation of this article, a wastewater permit or order issued hereunder, or any other pretreatment requirement, the Superintendent or his agent may serve upon said user a written notice of violation. Within 10 days of receipt of this notice, an explanation of the violation and the satisfactory correction and prevention thereof, to include specific required actions, shall be submitted to the Superintendent. Submission of this plan in no way relieves the user of a liability for any violations occurring before or after the receipt of the notification of violation. Nothing in this section shall limit the authority of the Town to take emergency action without first issuing a notice of violation.
The Superintendent is hereby empowered to enter into consent orders, assurances of voluntary compliance, or other similar documents establishing an agreement with the industrial user responsible for the noncompliance. Such orders shall include specific actions to be taken by the industrial user to correct the noncompliance within a time period also specified by the order. Consent orders shall have the same force and effect as administrative orders issued pursuant to §§ 136-69 and 136-70 below and shall be judicially enforceable.
The Superintendent may order any industrial user which causes or contributes to violation(s) of this article, wastewater permit or orders issued hereunder, or any other pretreatment requirement to appear before the Superintendent and show cause why a proposed enforcement action shall not be taken. Notice shall be served on the industrial user specifying the time and place for the meeting, the proposed enforcement action, the reason for such action, and a request that the user show cause why the proposed enforcement action should not be taken. The notice of the meeting shall be served personally or by registered, or certified mail (return receipt requested) at least 10 days prior to the hearing. Such notice may be served on any authorized representative of the industrial user. Whether or not the industrial user appears as noticed, immediate enforcement action may be pursued following the hearing date.
When the Superintendent finds that an industrial user has violated or continues to violate the article, permits or orders issued hereunder, or any other pretreatment requirement, he may issue an order to the industrial user responsible for the discharge directing that, following a specified time period, sewer service shall be disconnected unless adequate treatment facilities, devices, or other regulated appurtances are installed and properly operated. Compliance orders may also contain such other requirements as might be reasonably necessary and appropriate to address the noncompliance, including additional self-monitoring, and management practices designed to minimize the amount of pollutants discharged to the sewer. Furthermore, the Superintendent may continue to require such additional self-monitoring for at least 90 days after consistent compliance has been achieved, after which time the self-monitoring conditions in the discharge permit shall control.
When the Superintendent finds that an industrial user has violated or continues to violate the article, permits or orders issued hereunder, or any other pretreatment requirement, the Superintendent may issue an order to the industrial user directing it to cease and desist all such violations and directing the user to:
A. 
Immediately comply with all requirements; and
B. 
Take such appropriate remedial or preventive action as may be needed to properly address a continuing or threatened violation, including halting the operation and/or terminating the discharge.
Notwithstanding any other section of this article, any user which is found to have violated any provision of this article, permits and orders issued hereunder, or any other pretreatment requirement shall be fined in the amount of $1,000 per violation, and not to exceed a total of $5,000, in addition to relevant damages incurred by the municipality. Such fines shall be assessed on a per-violation, per-day basis. In the case of monthly or long-term average discharge limits, fines shall be assessed for each business day during the period of violation.
A. 
Assessments may be added to the user's next scheduled sewer service charge, and the Superintendent shall have such other collection remedies as may be available for other service charges and fees.
B. 
Unpaid charges, fines, and penalties shall, after 30 calendar days, be assessed an additional penalty of 20% of the unpaid balance, and interest shall accrue thereafter at a rate of 7% per month. Furthermore, these unpaid charges, fines, and penalties, together with interest therefrom shall constitute a lien against the individual user's property.
C. 
Industrial users desiring to dispute such fines must file a written request for the Superintendent to reconsider the fine along with full payment of the fine amount within 10 days of being notified of the fine. Where the Superintendent believes the request has merit, he shall convene a hearing on the matter within 15 days after receiving the request from the indutrial user. The Town may add the cost of preparing administrative enforcement actions, such as notices and orders to assess the fine.
A. 
In addition to those provisions in § 136-48 of this article, any industrial user which violates the following conditions of this article, wastewater permits, or orders issued hereunder is subject to permit termination:
(1) 
Violation of permit conditions;
(2) 
Failure to accurately report the wastewater constituents and characteristics of its discharge;
(3) 
Failure to report significant changes in operations or wastewater volume, constituents and characteristics prior to discharge; or
(4) 
Refusal of reasonable access to the user's premises for the purpose of inspection, monitoring, or sampling.
B. 
Noncompliant industrial users will be notified of the proposed termination of their wastewater permit and be offered an opportunity to show cause under § 136-68 of this article why the proposed action should not be taken.
The Superintendent may suspend the wastewater permit of an industrial user for a period not to exceed 30 days, whenever such suspension is necessary in order to stop a threatened discharge which reasonably appears to present or cause an imminent or substantial endangerment to the health or welfare of persons, interferes with operation of the municipal wastewater system, or which presents an endangerment to the environment.
A. 
Any industrial user notified of a suspension of its permit shall immediately stop or eliminate its contribution. In the event of an industrial user's refusal to immediately comply voluntarily with the suspension order, the Superintendent shall take such steps as deemed necessary, including immediate severance of the sewer connection, to prevent or minimize damage to the system, its receiving soil, or endangerment to any individuals. The Superintendent shall allow the industrial user to recommence its discharge when the user has demonstrated to the satisfaction of the Town that the period of endangerment has passed, unless the termination proceedings set forth in § 136-72 are initiated against the user.
B. 
An industrial user which is responsible, in whole or in part, for any discharge presenting imminent endangerment shall submit a detailed written statement describing the cause of the harmful contribution and the measures taken to prevent any future occurrence to the Superintendent prior to the date of any show cause or termination hearing under §§ 136-68 and 136-72.
Whenever an industrial user has violated or continues to violate the provisions of this article, permits or orders issued hereunder, or any other pretreatment requirement, the Superintendent, through the Town's Attorney, may petition the Municipal Court of New Castle County for the issuance of a temporary or permanent injunction, as may be appropriate, which restrains or compels the specific performance of the wastewater permit, order or other requirement imposed by this article on activities of the industrial user. Such other action as may be appropriate for legal and/or equitable relief may also be sought by the Town. The Court shall grant the injunction without requiring a showing of a lack of an adequate remedy at law.
Any industrial user that has violated or continues to violate this article, any permits or orders issued hereunder, or any other pretreatment requirement shall be liable to the Superintendent for a maximum civil penalty of $5,000, but not less than $1,000 per violation per day. In the case of a monthly or longer term average discharge limit, penalties shall accrue for each business day during the period of the violation.
A. 
The Superintendent may recover reasonable attorney's fees, court costs, and other expenses associated with the enforcement activities, including sampling and monitoring expenses, and the cost of any actual damages incurred by the Town.
B. 
In determining the amount of civil liability, the court shall take into account all relevant circumstances, including, but not limited to, the extent of harm caused by the violation, the magnitude and duration, any economic benefit gained through the industrial user's violation, corrective actions by the industrial user, the compliance history of the user, and any factor as justice requires.
C. 
Where appropriate, the Superintendent may accept mitigation projects in lieu of the payment of civil penalties where the project provides a valuable service to the Town and the industrial user's expense in undertaking the project is at least 150% of the civil penalty.
A. 
Any industrial user who willfully or negligently violates any provisions of this article, any orders or permits issued hereunder, or any other pretreatment requirement shall, upon conviction, be guilty of a misdemeanor, punishable by a fine of not more than $1,000 per violation per day or imprisonment for not more than one-year or both.
B. 
Any industrial user who knowingly makes any false statements, representations, or certifications in any application, record, report, plan or other document filed or required to be maintained pursuant to this article, or wastewater permit, or who falsifies, tampers with or knowingly renders inaccurate any monitoring device or method under this article shall, upon conviction, be punishable by a fine of not more than $1,000 per violation per day or imprisonment for not more than one year, or both.
C. 
In the event of a second conviction, the user shall be punishable by a fine not to exceed $3,000 per violation per day or imprisonment for not more than three years, or both.
The Superintendent may decline to reissue a permit to any industrial user which has failed to comply with the provisions of this article, any orders, or a previous permit issued hereunder unless such user first files a satisfactory bond, payable to the Town, in a sum not to exceed a value determined by the Superintendent to be necessary to achieve consistent compliance.
The Superintendent may decline to reissue a permit to any industrial user which has failed to comply with the provisions of this article, any orders, or a previous permit issued hereunder unless such user first submits proof that it has obtained financial assurance sufficient to restore or repair damage to the municipal wastewater system caused by its discharge.
Whenever an industrial user has violated or continues to violate the provisions of this article, orders, or permits 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 its ability to comply.
Any violations of the prohibitions or effluent limitations of this article, permits, or orders issued hereunder is hereby declared a public nuisance and shall be corrected or abated as directed by the Superintendent or his designee. Any person(s) creating a public nuisance shall be subject to the provisions of the Town codes governing such nuisance, including reimbursing the Town for any cost incurred by the Town in removing, abating, and/or remedying said nuisance.
Industrial users which have not achieved consistent compliance with applicable pretreatment standards and requirements are not eligible to receive a contractual award for the sale of goods or services to the Town. Existing contracts for the sale of goods or services to the Town held by the industrial user found to be in significant violation with pretreatment standards may be terminated at the discretion of the Town.
A. 
Upset.
(1) 
An upset shall be an affirmative defense to an enforcement action brought against a user for violating a pretreatment standard and requirement if the following conditions are met:
(a) 
The user can identify the cause of the upset.
(b) 
The facility was operating in a prudent and workmanlike manner at the time of the upset and was in compliance with applicable O&M procedures.
(c) 
The user submits, within 24 hours of becoming aware of the upset, a description of the discharge(s) and its causes, the period of noncompliance (if not corrected, then the time the noncompliance is anticipated to end), and the steps being taken to reduce, eliminate and prevent recurrence of the noncompliance.
(d) 
If this report is given orally, the user must also submit a written report containing such information within five days unless waived by the Superintendent.
(2) 
"Upset" shall mean an exceptional incident in which there is unintentional and temporary noncompliance with categorical pretreatment standards and requirements because of factors beyond the reasonable control of the industrial user. Noncompliance caused by operational error, improperly designed pretreatment facilities, inadequate pretreatment facilities, lack of preventive maintenance, or careless or improper operation does not constitute an "upset."
B. 
General/specific prohibitions. An industrial user shall have an affirmative defense to an enforcement action brought against it for noncompliance with the general and specific prohibitions in Section 2.1 of this article if it can prove that it did not know or have reason to know that its discharge would cause pass through 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 spray irrigation permits, and in the case of interference, in compliance with applicable sludge use or disposal requirements.
C. 
Bypass. The intentional diversion of waste streams from any portion of an individual user's treatment facility shall be an affirmative defense to an enforcement action brought against the industrial user if the user can demonstrate that such a bypass was unavoidable to prevent loss of life, personal injury, or severe property damage. In order to be eligible for the affirmative defense, the industrial user must demonstrate that there was no feasible alternative to the bypass as required by 40 CFR 403.17.
