Nonexclusive remedies. 17.68.010 Notification of violation. Whenever the director finds that any user has violated or is violating any provision of this ordinance, or any wastewater discharge permit, order, rule or regulation issued or promulgated hereunder, or any other pretreatment requirement, the director may serve upon said user a written Notice of Violation. Such written notice shall be served in 8 person or by certified mail, return receipt requested. Within five (5) days after the receipt of such notice, an explanation for the violation and a plan for the satisfactory correction and prevention thereof, which shall include specific required actions, shall be submitted by the user to the director. Submission of this plan in no way relieves the user of liability for any violations occurring before or after receipt of the Notice of Violation. Nothing in this section shall limit the authority of the POTW to take any action, including emergency actions or any other enforcement action, without first issuing a Notice of Violation. 17.68.020 Consent orders. The director is hereby empowered to enter into consent orders, assurances of voluntary compliance, or other similar documents establishing an agreement with any user responsible for noncompliance. Such orders will include specific action to be taken by the user. Consent orders shall have the same force and effect as administrative orders issued pursuant to Sections 17.68.040 and 17.68.050 below, and shall be judicially enforceable. 17.68.030 Show Cause Hearing. The director may order any user which causes or contributes to violation(s) of any provisions of this ordinance, or any wastewater discharge permit or order, rule or regulation issued or promulgated hereunder, or any other pretreatment standard or requirement, to appear before the director and show cause why a proposed enforcement action should not be taken. Notice shall be served on the user, which notice shall specify the time and place for the meeting, 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. Such written notice shall be served in person on any authorized 9 . representative of the user, or by certified mail, return receipt requested, at least seven (7) days prior to the hearing. Whether or not the user appears as ordered, immediate enforcement action may be pursued following the hearing date. A show cause hearing shall not be a prerequisite for taking any other actions against the user. 17.68.040 Compliance orders. When the director finds that a user has violated or continues to violate any provision of this ordinance, or any wastewater discharge permit, rule or regulation issued or promulgated hereunder, or any other pretreatment standard or requirement, he may issue an order to the user responsible for the violation directing that the user come into compliance within thirty (30) days. If the user does not come into compliance within thirty (30) days, sewer service may be discontinued. Compliance orders may also contain other requirements to address noncompliance, including additional self -monitoring, and management practices designed to minimize the amount of pollutants discharged to the POTW. A compliance order may not extend the deadline for compliance established for a federal pretreatment standard or requirement, nor does a compliance order release the user of liability for any violation, including any continuing violation. Issuance of a compliance order shall not be a prerequisite to taking any other action against the user. 17.68.050 Cease and desist orders. When the director finds that a user is violating any provision of this ordinance, any wastewater discharge permit, rule or regulation issued or promulgated hereunder, or any other pretreatment standard or requirement, or that the user's past violations are likely to recur, the director may issue an order to the user directing it to cease and desist all such violations and directing the user to: 10 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 operations and/or terminating the discharge. Issuance of a cease and desist order shall not be a prerequisite to taking any other action against the user. 17.68.060 Administrative fines. A. Notwithstanding any other section of this ordinance, any user found to have violated any provision of this ordinance, or any wastewater discharge permit, order, rule or regulation issued or promulgated hereunder, or any other pretreatment standard or requirement, may be fined in an amount not greater than $10,000 per day, as determined by the director in his reasonable discretion. Such fines shall be assessed on a per day, per violation basis. In the case of monthly or other long term average discharge limits, fines shall be assessed for each day during the period of violation. B. The POTW may charge a user for the costs of preparing administrative enforcement actions, such as notices and orders, which charge may be assessed whether or not a fine under subsection (A) is also imposed. C. Assessments for fines and/or administrative costs may be added to the user's next scheduled sewer service charge, and the director shall have such other collection remedies as may be available for other service charges and fees. D. Unpaid charges, fines, assessments and penalties shall, after sixty (60) calendar days, be assessed an additional penalty of ten (10) percent of the unpaid balance. Thereafter, interest on any unpaid balances, including penalties, shall accrue at a rate of 11 ,1 % per month. A lien against the individual user's property will be sought for unpaid charges, fines, and penalties. E. Users desiring to dispute such fines or assessments must file a written request for the director to reconsider the fine or assessment, along with full payment thereof within thirty (30) days of being notified of the fine or assessment. The director shall convene a hearing on the matter within fourteen (14) days of receiving the request from the user. In the event the user's appeal is successful, any amounts paid by the user to the POTW shall be returned to the user , without interest. F. The imposition of an administrative fine, assessment or other charge shall not be a prerequisite for taking any other action against the user. 17.68.070 Emergency suspensions. The director may order the immediate suspension or shut-off of a user's discharge (after informal notice to the user), whenever such suspension or shut-off is necessary in order to stop an actual or threatened discharge which reasonably appears to present or cause a risk of an imminent or substantial (a) damage to the POTW, (b) endangerment to the health or welfare of any residents of the POTW, (c) interference with the operation of the POTW, or (d) endangerment to the environment. Any user notified of a suspension of its discharge shall immediately stop or eliminate its contribution. In the event of a user's failure to immediately comply voluntarily with the suspension order, the director shall take such steps as deemed necessary, including immediate severance of the sewer connection, to enforce such order. The director shall allow the user to recommence its discharge when the user has demonstrated to the satisfaction of the POTW that the period of endangerment has passed, unless the termination proceedings set forth in Section 12 17.68.080 are initiated against the user. A user that is responsible, in whole or in part, for any discharge presenting imminent endangerment, shall submit to the director a detailed written statement describing the causes of the harmful contribution and the measures taken to prevent any future occurrence, prior to the date of any show cause or termination of discharge hearing under Sections 17.68.030 and 17.68.080. Nothing in this section shall be interpreted as requiring a hearing prior to any emergency suspension under this Section. 17.68.080 Termination of Discharge. In concert with the wastewater discharge permit revocation provisions in Section 17.52.160 of this ordinance, any user committing any of the following acts or omissions is subject to discharge termination. A. Violation of any provisions of this ordinance or any wastewater discharge permit, order, rule or regulation issued or promulgated hereunder; B. Failure to accurately report the wastewater constituents and characteristics of its discharge; C. Failure to report significant changes in operations or wastewater volume, constituents and characteristics prior to discharge; D. Refusal of reasonable access to the user's premises for the purpose of inspection, monitoring or sampling; or E. Violation of the standards in Chapter 17.36 of this ordinance. The user will be notified of the proposed termination of its discharge and be offered an opportunity to show cause under Section 17.68.030 of this ordinance why the proposed action should not be taken. 13 17.68.090 Injunctive relief. Whenever a user has violated a pretreatment standard or requirement or continues to violate any provisions of this ordinance, or any wastewater discharge permit, order, rule or regulation issued or promulgated hereunder, or any other pretreatment requirement, the POTW may petition any court of competent jurisdiction for the issuance of a temporary or permanent injunction, as appropriate, which restrains or compels the specific performance of the wastewater discharge permit, order, rule, regulation or other requirement. In addition, the POTW may recover reasonable attorney's fees, court costs, and other expenses of litigation by appropriate legal action against the user found to have violated any provision hereof, or of any wastewater discharge permit, order, or any other rule or regulation issued or promulgated hereunder. Such other action as appropriate for legal and/or equitable relief may also be sought by the POTW. A petition for injunctive relief need not be filed as a prerequisite to taking any other action against a user. 17.68.100 Civil fine pass through recovery. In the event that a user discharges such pollutants which cause the POTW to violate any conditions of its UPDES Permit and the POTW is fined by the EPA, the State of Utah or Salt Lake County for such violations, then such user shall be fully liable for the total amount of the fines and civil penalties assessed against the POTW by the EPA or the State of Utah and administrative costs incurred. 17.68.110 Referral to State of Utah for action. The POTW may refer to the State of Utah criminal violations of any pretreatment standards or permit conditions. The Utah Attorney General's office will offer Salt Lake 14 County the option to prosecute the violator. Should Salt Lake County decline, the State, at its discretion, may initiate appropriate criminal action. The POTW shall assist the Utah Attorney General's office or Salt Lake County any way it can with appropriate support for the action taken. 17.68.120 Performance bonds. The director may decline to reissue a wastewater discharge permit to any user which has failed to comply with the provisions of this ordinance, or of any previous wastewater discharge permit, order, rule or regulation issued or promulgated hereunder, unless such user first files a satisfactory bond, payable to the POTW, in a sum not to exceed a value determined by the director to be necessary to achieve consistent compliance. 17.68.130 Liability insurance. The director may decline to reissue a wastewater discharge permit to any user which has failed to comply with the provisions of this ordinance, or of any previous wastewater discharge permit, order, rule or regulation issued or promulgated hereunder, unless the user first submits proof that it has obtained financial assurances sufficient to restore or repair damage to the POTW caused by its discharge. 17.68.140 Water supply severance. Whenever a user has violated or continues to violate the provisions of this ordinance, or of any wastewater discharge permit, order, rule or regulation issued or promulgated hereunder, water service to the user may be discontinued. Service will only recommence, at the user's expense, after it has satisfactorily demonstrated its ability to comply. 15 17.68.150 Public nuisances. Any violation of the provisions of this ordinance, or of any wastewater discharge permit, order, rule or regulation issued or promulgated hereunder, is hereby declared a public nuisance and shall be corrected or abated as directed by the director. Any person(s) creating a public nuisance shall be subject to the provisions of the Salt Lake City Code governing nuisances, including reimbursing the POTW for any costs incurred in removing, abating or remedying said nuisance. 17.68.160 Contractor listing. Users which are found to be in significant non-compliance with any provisions of this ordinance, or of any wastewater discharge permit, order, rule or regulation issued or promulgated hereunder, are not eligible to receive a contractual award for the sale of goods or services to the POTW. Existing contracts for the sale of goods or services to the POTW held by a user found to be in significant noncompliance with any provisions of this ordinance, or of any wastewater discharge permit, order, rule or regulation issued or promulgated hereunder, may be terminated at the discretion of the POTW. 17.68.170 Nonexclusive Remedies The provisions of Sections 17.68.010 through 17.68.160 are not exclusive remedies. The POTW reserves the right to take any, all, or any combination of these actions against a noncompliant user. Enforcement of pretreatment violations will generally be in accordance with the POTW's enforcement response plan. However, the POTW reserves the right to take other action against any user when the circumstances warrant. Further, the POTW is empowered to take more than one enforcement action against any noncompliant user. These actions may be taken concurrently. 16 SECTION 17. There are hereby enacted new Sections 17.69.010 through 17.69.030 of the Salt Lake City Code, to read as follows: CHAPTER 17.69 AFFIRMATIVE DEFENSES Sections: 17.69.010 Upset. 17.69.020 General/specific prohibitions. 17.69.030 Bypass. 17.69.010 Upset. A. For the purposes of this Section, "upset" means an exceptional incident in which there is unintentional and temporary noncompliance with categorical pretreatment standards because of factors beyond the reasonable control of the user. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. B. An upset shall constitute an affirmative defense to an action brought for noncompliance with categorical pretreatment standards if the requirements of subsection (C) are met. C. A user who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: 1. An upset occurred and the user can identify the cause of the upset; 2. The facility was at the time being operated in a prudent and workmanlike manner and in compliance with applicable operation and maintenance procedures; 17 3. The user has submitted the following information to the POTW and treatment plant operator within 24 hours of becoming aware of the upset (if this information is provided orally, a written submission must be provided within five (5) days): (i) A description of the indirect discharge and cause of noncompliance; (ii) The period of noncompliance, including exact dates and times or, if not corrected, the anticipated time the noncompliance is expected to continue; and (iii) Steps being taken and/or planned to reduce, eliminate and prevent recurrence of the noncompliance. D. In any enforcement proceeding, the user seeking to establish the occurrence of an upset shall have the burden of proof. E. Users will have the opportunity for a judicial determination on any claim of upset in an enforcement action brought for noncompliance with categorical pretreatment standards. F. The user 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 has failed. 18 17.69.020 General/specific prohibitions. An user shall have an affirmative defense to an enforcement action brought against it for noncompliance with the general and specific prohibitions in Chapter 17.36 of this ordinance if it can prove that it did not know or have reason to know that its discharge, along or in conjunction with discharges from other sources, 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 prior discharge when the POTW was regularly in compliance with its UPDES permit, and in the case of interference, was in compliance with applicable sludge use or disposal requirements. 17.69.030 Bypass. A. (1) "Bypass" means the intentional diversion of waste streams from any portion of a user's treatment facility. (2) "Severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. B. 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 subsections (C) and (D) of this Section. 19 C. (1) If a user knows in advance of the need for a bypass, it shall submit prior notice to the POTW, at least ten days before the date of the bypass if possible. (2) A user shall submit oral notice of an unanticipated bypass that exceeds applicable pretreatment standards to the POTW within 24 hours from the time it becomes aware of the bypass. A written submission shall also be provided within 5 days of the 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. The user shall also set forth in writing the steps taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass. The POTW may waive the written report on a case -by -case basis if the oral report has been received within 24 hours. D. (1) Bypass is prohibited, and the POTW may take enforcement action against a user for a bypass, unless: (i) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; (ii) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (iii) The user submitted notices as required under subsection (C) of this Section. 20 (2) The POTW may approve an anticipated bypass, after considering its adverse effects, if the POTW determines that it will meet the three conditions listed in (D)(1) of this Section. SECTION 18. Section 17.72.010, Salt Lake City Code, is hereby repealed in its entirety: SECTION 19. Section 17.72.020, Salt Lake City Code, is hereby repealed in its entirety: SECTION 20. Section 17.72.030, $alt Lake City Code, is hereby amended to read as follows: 17.72.030 Schedule 1-Rates and Fees. SCHEDULE 1 RATES AND FEES * * * C. Sewer Charge. 1. User Service Rate. (a) Each sewer service account shall be charged a monthly sewer fee equal to the greater of (i) eighty cents ($0.80) per one hundred (100) cubic feet of metered water usage, as determined below, or (ii) a minimum charge of three dollars and fifteen cents ($3.15). The average monthly water meter readings during the consecutive months of November, December, January, February and March (hereinafter "winter months"), shall be the basis for sewer billings for the twelve-month period beginning July 1 and ending June 30, immediately following such winter months. 21 (b) In cases where little or no water is used during one or more of the winter months, such that the average metered usage during such winter months cannot be reasonably assumed to reflect typical monthly usage for an account, the director may use other consumptive information specific to such account to determine average monthly minimum usage for sewer billing purposes. (c) Meter readings for sewer billing purposes shall only include meters which measure water which may enter the sewer system. (d) In the case of sewer users whose water usage is based in whole or in part on water sources other than the City, the city may require installation of a city approved meter, at the sewer user's expense, on the well(s) or other sources of water supply, for measurement by the City during the winter months to determine the sewer user's water use during the winter months. (e) For each single-family dwelling sewer user using water other than City water and desiring not to install a water meter as provided above, the director may waive the meter requirement, in which event the user will be charged for sewer service as provided in subsection E of this Section. 2. Surcharge. In addition to the User Service Rate set forth above, each user shall pay the following surcharge, for discharges in excess of the following benchmark wastewater discharge concentrations: 22 Category Surcharge for each lb. in excess of Benchmark Benchmark Discharge Concentrations Concentration (mg/liter) ($/lb.) COD 400 $0.025 BOD 200 $0.050 TSS 250 $0.050 Either a BOD or COD surcharge will be assessed, but not both. Nothing in this Section 17.72.30(C)(2) shall authorize discharges in excess of the maximum local limit concentrations established by the director pursuant to Section 17.36.090. D. *** E.
