Since the user will have already been in SNC to necessitate the show cause hearing, any action taken as a result of the hearing shall be in addition to any penalties levied for the SNC. Sec. 106-630. - Compliance orders. When the Control Authority finds that a user has violated or continues to violate any section of this ordinance, a wastewater discharge permit or order issued under this ordinance or any other pretreatment standard or requirement, the Control Authority may issue an order to the user responsible for the discharge directing that the user come into compliance within a specified time. If the user does not come into compliance within the time provided, sewer and/or water service may be discontinued unless adequate treatment facilities, devices, or other related appurtenances are installed and properly operated. Compliance orders also may contain other requirements to address the noncompliance, including the installation of pretreatment technology, additional self- monitoring and management practices designed to minimize the amount of pollutants discharged to the sewer. A compliance order may not extend the deadline for compliance established for a pretreatment standard or requirement, nor does a compliance order relieve the user of liability for any violation, including any continuing violation. Issuance of a compliance order shall not be a bar against or a prerequisite for taking any other action against the user. Sec. 106-631. - Cease and desist orders. (a) When the Control Authority finds that a user has violated or continues to violate any section of this ordinance, a wastewater discharge permit or order issued under this ordinance or any other pretreatment standard or requirement or that the user's past violations are likely to recur, the Control Authority may issue an order to the user directing it to cease and desist all such violations and directing the user to: (1) Immediately comply with all requirements; and (2) Take such appropriate remedial or preventative action as may be needed to properly address a continuing or threatened violation, including halting operations and/or terminating the discharge. (b) Issuance of a cease and desist order shall not be a bar against or a prerequisite for taking any other action against the user. Sec. 106-632. - Administrative fines. (a) When the Control Authority finds that a user has violated or continues to violate any section of this ordinance, a wastewater discharge permit or order issued under this ordinance or any other pretreatment standard or requirement, the Control Authority may fine such a user in an amount not to exceed $2,000.00. Such fine shall be assessed on a per-violation, per-day basis. For monthly or other long-term average discharge limits, fines shall be assessed for each day during the period of violation. Such assessments may be added to the user's next scheduled sewer service charge, and the Control Authority shall have such other collection remedies as he has to collect other service charges. (b) Unpaid charges, fines, and penalties shall, after 14 calendar days, be assessed an additional penalty of ten percent of the unpaid balance, and interest shall accrue thereafter at a rate of one percent per month for every month unpaid up to a maximum of ten percent per month. (c) A user desiring to dispute such fine must file a written request for the Control Authority to reconsider the fine along with full payment of the fine amount within ten days of being notified of the fine. When the Control Authority believes a request has merit, the Control Authority may convene a hearing on the matter within 15 days of receiving a request from the user. If the user's appeal is successful, the payment, together with any interest accruing thereto, shall be returned to the user. The Control Authority may add the costs of preparing administrative enforcement actions, such as notices and orders, to the fine. (d) Issuance of an administrative fine shall not be a bar against or a prerequisite for taking any other action against the user. Sec. 106-633. - Emergency suspensions. (a) The Control Authority may immediately suspend a user's discharge and/or water service, after informal notice to the user, whenever such suspension is necessary to stop an actual or threatened discharge which reasonably appears to present or cause an imminent or substantial endangerment to the health or welfare of persons. The Control Authority may also immediately suspend a user's discharge and/or water service, after notice and opportunity to respond, that threatens to interfere with operation of the publicly owned treatment works or which presents, or may present, an endangerment to the environment. (b) Any user notified of a suspension of its discharge shall immediately stop or eliminate its contribution. If a user fails to immediately comply voluntarily with the suspension order, the Control Authority may take such steps as deemed necessary, including immediate severance of the sewer connection, to prevent or minimize damage to the publicly owned treatment works, its receiving stream, or endangerment to any individuals. The Control Authority may allow the user to recommence its discharge when the user has demonstrated to the satisfaction of the Control Authority that the period of endangerment has passed, unless the termination proceedings in section 106-634 are initiated against the user. (c) A user that is responsible, in whole or in part, for any discharge presenting imminent endangerment shall submit a detailed written statement, describing the causes of the harmful contribution and the measures taken to prevent any future occurrence, to the Control Authority prior to the date of any show cause or termination hearing under section 106-629 or 106-634. (d) Nothing in this subdivision shall be interpreted as requiring a hearing prior to any emergency suspension under this section. Sec. 106-634. - Termination of discharge. (a) In addition to section 106-765, any user who violates the following conditions is subject to discharge termination: (1) Violation of wastewater discharge 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; (4) Refusal of reasonable access to the user's premises for the purpose of inspection, monitoring, sampling or industry categorization verification; (5) Violation of the pretreatment standards in subdivision II of division 4 of this ordinance; (6) Violation of any applicable state or federal law; or (7) Tampering with sampling equipment, sampling lines, or otherwise interfering with sampling or samples collected for the purpose of influencing or manipulating sample test results. (b) Such user will be notified of the proposed termination of its discharge and be offered an opportunity to show cause under section 106-629 why the proposed action should not be taken. Exercise of this option by the Control Authority shall not be a bar to or a prerequisite for taking any other action against the user. Sec. 106-635. - Liquidated damages. (a) Each wastewater discharge use permit issued to an industrial user, and as a condition of issuing such permit, shall contain the following: "In the event that the Control Authority determines that any user is in violation of any provisions of Chapter 106, Ordinance VII of the Code of Ordinances of the City of Wichita Falls, Texas, its wastewater discharge permit, or orders issued hereunder, or any other pretreatment standard or requirement, the Control Authority shall notify the user of such violation and require the user to cure the violation within the time specified in the notice. The user shall respond in writing to the notice of violation within 10 business days from receipt of such notice, setting forth the steps taken to correct the violation. The Control Authority may extend the time for such response upon a showing of just cause by the user. If the Control Authority determines that the user is continuing the violation, the Control Authority may assess liquidated damages at a minimum of$1,000.00 per violation, per day." (b) The user retains the right to seek review by the city council of any damages assessed under this section and the wastewater discharge permit. (c) Assessments may be added to the user's next scheduled sewer service charge, and the Control Authority shall have such other collection remedies as may be available for other service charges and fees. (d) Issuance of an assessment under this section shall not be a prerequisite for taking any other action against the user. Secs. 106-636-106-660. - Reserved. Subdivision IV. - Judicial Enforcement Sec. 106-661. - Authority. If any person discharges sewage, industrial wastes, or other wastes into the wastewater disposal system contrary to this ordinance or any order or permit issued under this ordinance, the Control Authority, through the city attorney, may commence an action for appropriate legal and/or equitable relief in the municipal court for the city. Sec. 106-662. - Injunctive relief. When the Control Authority finds that a user has violated or continues to violate any section of this ordinance, a wastewater discharge permit, or order issued under this ordinance or any other pretreatment standard or requirement, the Control Authority may petition the courts through the city attorney for the issuance of a temporary, preliminary, and/or permanent injunction, as appropriate, which restrains or compels the specific performance of the wastewater discharge permit, order, or other requirement imposed by this ordinance on activities of the user. The Control Authority may also seek such other action as is appropriate for legal and/or equitable relief, including a requirement for the user to conduct environmental remediation. A petition for injunctive relief shall not be a bar against or a prerequisite of taking any other action against a user. The Control Authority shall have such remedies to collect these fees as it has to collect other sewer service charges. Sec. 106-663. - Civil penalties. (a) A user who has violated or continues to violate any section of this ordinance, a wastewater discharge permit, or order issued under this ordinance or any other pretreatment standard or requirement shall be liable to the city for a maximum civil penalty of$2,000.00 per violation per day plus actual damages incurred by the publicly owned treatment works. For a monthly or other long term average discharge limit, penalties shall accrue for each day during the period of the violation. (b) The Control Authority may recover reasonable attorneys' fees, court costs, and other expenses associated with enforcement activities, including sampling and monitoring expenses, and the cost of any actual damages incurred by the city. (c) 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 of the violation, any economic benefit gained through the user's violation, corrective actions by the user, the compliance history of the user, and any other factor as justice requires. (d) Filing a suit for civil penalties shall not be a bar against or a prerequisite for taking any other action against a user. Sec. 106-664. - Criminal prosecution. (a) For the purpose of this ordinance, the city shall enact all criminal authorities authorized under state law. (b) Any user that willfully or negligently violates any section of this ordinance, any orders or wastewater discharge permits issued under this ordinance or any other pretreatment requirement shall, upon conviction, be guilty of a misdemeanor, punishable by a fine of not more than $2,000.00 per violation, per day as provided in section 106-632. (c) Any user that knowingly makes any false statements, representations, or certifications in any application, record, report, plan, or other documentation filed or required to be maintained pursuant to this ordinance, the wastewater discharge permit or an order or who falsifies, tampers with or knowingly renders inaccurate any monitoring device or method required under this ordinance shall, upon conviction, be punished by a fine per violation. (d) The purpose of criminal prosecution is to punish noncompliance through court proceedings and to deter future noncompliance. The city will enforce compliance with all ordinances in municipal court and will seek the assistance of the district attorney and/or the U.S. Attorney's office to enforce state statutes and federal laws. Sec. 106-665. - Remedies nonexclusive. The remedies provided for in this ordinance are not exclusive. The Control Authority may take any, all, or any combination of the actions in this subdivision against a noncompliant user. Enforcement of pretreatment violations will generally be in accordance with the city's enforcement response plan. However, the Control Authority may take other action against any user when the circumstances warrant. Further, the Control Authority is empowered to take more than one enforcement action against any noncompliant user. Secs. 106-666-106-690. - Reserved. Subdivision V. - Affirmative Defenses to Discharge Violations Sec. 106-691. - Act of God Affirmation Defense If a person can establish that an event that would otherwise be a violation of this ordinance within the Control Authority's jurisdiction or an ordinance adopted or an order or a permit issued under such an ordinance was caused solely by an act of God, war, strike, riot, or other catastrophe, the event is not a violation of the ordinance or permit. Sec. 106-692. - Prohibited discharge standards. A user shall have an affirmative defense to an enforcement action brought against him for noncompliance with the general prohibitions in section 106-816 or the specific prohibitions in section 106-817 if the user can prove that he did not know or have reason to know that the discharge, alone or in conjunction with discharges from other sources, would cause pass through or interference and that either: (1) 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 (2) No local limit exists, but the discharge did not change substantially in nature or constituents from the user's prior discharge when the city was regularly in compliance with its National Pollutant Discharge Elimination System permit and, in the case of interference, was in compliance with applicable sludge use or disposal requirements. Sec. 106-693. - Bypass. (a) The following words, terms and phrases, when used in this ordinance, shall have the meanings ascribed to them in this subsection, except where the context clearly indicates a different meaning: Bypass means the intentional diversion of wastestreams from any portion of a user's treatment facility. 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. The term "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 ensure efficient operation. These bypasses are not subject to subsections (c) and (d) of this section. (c) Notice of bypass shall be given in accordance with the following: (1) If a user knows in advance of the need for a bypass, it shall submit prior notice to the Control Authority, at least ten days before the date of the bypass, if possible. (2) A user shall submit oral notice to the Control Authority 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 five 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; if the bypass has not been corrected, the anticipated time it is expected to continue; and the steps taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass. The Control Authority may waive the written report on a case-by-case basis if the oral report has been received within 24 hours. (d) Enforcement action curtailments shall be as follows: (1) Bypass is prohibited, and the Control Authority 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 backup 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 preventative maintenance; and c. The user submitted notices as required under subsection (c) of this section. (2) The Control Authority may approve an anticipated bypass, after considering its adverse effects, if the Control Authority determines that it will meet the three conditions listed in subsection (d)(1) of this section. Secs. 106-694-106-720. - Reserved. Subdivision VI. - Compliance Monitoring Sec. 106-721. - Inspection and sampling. In accordance with 40 CFR 403.8(f)(2)(v), the Control Authority shall randomly inspect and sample each significant industrial user once a year in order to verify self- monitoring reports and other user-provided information. This section shall not preclude the Control Authority from sampling and/or inspecting significant industrial users more frequently or from sampling or inspecting any nonsignificant industrial user or any other user. Sec. 106-722. - Right of entry. (a) The Control Authority and/or the approval authority shall have the right to enter the premises of any user, whether or not the user possesses a wastewater discharge permit, to determine whether the user is complying with all the requirements of this ordinance and any wastewater discharge permit or order issued under this ordinance. A user shall allow the Control Authority and/or the approval authority ready access to all parts of the premises for the purpose of sampling, records examination and copying, and the performance of any additional duties, including determination and verification of proper classification of the user as a categorical, noncategorical, significant, or nonsignificant industrial user. (b) Where a user has security measures in force which require proper identification and clearance before entry into its premises, the user shall make necessary arrangements with its security guards so that, upon presentation of suitable identification, the Control Authority and/or the approval authority will be permitted to enter without delay for the purposes of performing specific responsibilities. (c) The Control Authority shall have the right to set up on the user's property or require installation of such devices as are necessary to conduct sampling and/or metering of the user's operations. (d) The Control Authority may require the user to install sampling equipment, monitoring equipment, metering equipment, and/or control manholes as necessary. The facility's sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the user at his own expense. All devices used to measure wastewater flow and quality shall be calibrated at appropriate intervals to ensure their accuracy. (e) Any temporary or permanent obstruction, whether object, condition, or otherwise, to safe and easy access to the facility or the facility's control point shall be promptly removed by the user at the written or verbal request of the Control Authority and shall not be replaced. The costs of clearing such access shall be borne by the user. (f) Unreasonable delays in allowing the Control Authority and/or the approval authority access to the user's premises shall be a violation of this ordinance. (g) The right of access of the Control Authority and/or the approval authority shall extend to but not be limited to any premises where there is a discharge source or pretreatment system located or where records are required to be kept by this ordinance or under 40 CFR 403. To make a comprehensive determination of user's compliance status, the Control Authority and/or the approval authority shall have access to all areas of the facility, including but not limited to areas where chemicals and raw materials are stored. This right shall be considered at least as extensive as the authority provided under section 308 of the Act. (h) During the course of any visit, the Control Authority and/or the approval authority may document any part or process of the facility by written document, still photography, video, audio, or any other recording method deemed appropriate by the Control Authority and/or the approval authority. The user may use the procedures in section 106-569 to request that portions of the documentation be considered confidential information. (i) The user shall not deny access by the Control Authority and/or the approval authority to any area of the facility for any reason, including but not limited to proprietary processes, security clearance, safety concern, or personal privacy. Any necessary arrangements for access to all areas shall have been made by the user beforehand so that upon presentation of suitable identification, the Control Authority and/or the approval authority shall be permitted to enter any area of the facility without reasonable delay for the purposes of performing specific responsibilities. The failure of the user to make any such necessary arrangements shall not constitute a valid reason for the user to deny entrance by the Control Authority and/or the approval authority to any area of the facility. Sec. 106-723. - Search warrants. If the Control Authority and/or the approval authority 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 ordinance or that there is a need to inspect and/or sample as part of a routine inspection and sampling program of the city designed to verify compliance with this ordinance or any permit or order issued under this ordinance or to protect the overall public health, safety and welfare of the community, the Control Authority may seek issuance of a search warrant. Secs. 106-724-106-750. - Reserved. DIVISION 3. - WASTEWATER DISCHARGE PERMIT Sec. 106-751. - Denial or conditions of new or increased contributions. The Control Authority may deny or condition new or increased contributions of pollutants or changes in the nature of pollutants to the publicly owned treatment works by industrial users where such contributions do not meet applicable pretreatment standards and requirements or where such contributions would cause the publicly owned treatment works to violate its Texas Pollutant Discharge Elimination System permit. Sec. 106-752. - Wastewater analysis. When requested by the Control Authority, a user must submit information on the nature and characteristics of its wastewater within a reasonable time specified by the Control Authority. The Control Authority is authorized to prepare a form for this purpose and may periodically require users to update this information. Sec. 106-753. - Requirements. (a) No significant industrial user shall discharge wastewater into the publicly owned treatment works without first obtaining a wastewater discharge permit from the Control Authority, except that a significant industrial user that has filed a timely application pursuant to section 106-754 or 106-755 may continue to discharge for the time period specified therein. (b) The Control Authority may require other users to obtain wastewater discharge permits as necessary to carry out the purposes of this ordinance. (c) Any violation of the terms and conditions of a wastewater discharge permit shall be deemed a violation of this ordinance and subjects the wastewater discharge permittee to the sanctions set out in sections 106-751-106-759 and sections 106-614 and 106- 615 and subdivisions IV and V of division 2 of this ordinance. Obtaining a wastewater discharge permit does not relieve a permittee of its obligation to comply with all federal and state pretreatment standards or requirements or with any other requirements of federal, state, and local law. Sec. 106-754. - Existing connections. Any user required to obtain a wastewater discharge permit who was discharging wastewater into the publicly owned treatment works prior to the effective date of the ordinance from which this section derives and who wishes to continue such discharges in the future shall, within 30 days after such date, apply to the Control Authority for a wastewater discharge permit in accordance with section 106-757 and shall not cause or allow discharges to the publicly owned treatment works to continue after 60 days of the effective date of the ordinance from which this section derives except in accordance with a wastewater discharge permit issued by the Control Authority. All users currently under a permit may continue to discharge wastewater for the duration of the permit with the provision that all prohibitions in this ordinance shall be considered to be in force at the effective date of the ordinance from which this ordinance derives. Sec. 106-755. - New connections. Any user required to obtain a wastewater discharge permit who proposes to begin or recommence discharging into the publicly owned treatment works must obtain such a permit prior to the beginning or recommencing of such discharge. An application for this wastewater discharge permit, in accordance with section 106-757, must be filed at least 60 days prior to the date upon which any discharge will begin or recommence. Sec. 106-756. - Extrajurisdictional industrial users. This ordinance shall apply to all persons outside the city who are, by contract or agreement with the city, users of the city's publicly owned treatment works, and thus such users may be required to obtain a wastewater discharge permit in accordance with all applicable sections of this division. Sec. 106-757. - Application contents. (a) All users required to obtain a wastewater discharge permit must submit a permit application. The Control Authority may require all users to submit as part of an application the following information: (1) All information required by section 106-881(b); (2) Description of activities, facilities, and plant processes on the premises, including a list of all raw materials and chemicals used or stored at the facility which are or could accidentally or intentionally be discharged to the publicly owned treatment works; (3) Number and type of employees, hours of operation, and proposed or actual hours of operation; (4) Each product produced by type, amount, process and rate of production; (5) Type and amount of raw materials processed (average and maximum per day); (6) Site plans, floor plans, mechanical and plumbing plans, and details to show all sewers, floor drains, and appurtenances by size, location, and elevation, and all points of discharge; (7) Time and duration of discharges; and (8) The location for monitoring all wastes covered by the permit (9) Flow Measurements Information showing the measured average daily and maximum daily flow, in gallons per day, to the POTW from regulated process streams and other streams, as necessary to allow us of the combined wastestream formula (40 CFR 403.6(e)).

Secs. 106-768-106-790. - Reserved. DIVISION 4. - SEWER USE REGULATIONS Subdivision I. - In General Secs. 106-791-106-815. - Reserved. Subdivision II. - Prohibited Discharges Sec. 106-816. - General prohibitions. No user shall introduce or cause to be introduced into the publicly owned treatment works any pollutant or wastewater which causes pass through or interference. These general prohibitions and the specific prohibitions in section 106-817 apply to all users of the publicly owned treatment works, whether or not they are subject to categorical pretreatment standards or any other national, state, or local pretreatment standards or requirements. Sec. 106-817. - Specific prohibitions. (a) No user shall introduce or cause to be introduced into the publicly owned treatment works the following pollutants, substances, or wastewater: (1) Pollutants which create a fire or explosive hazard in the publicly owned treatment works, including but not limited to wastestreams with a closed-cup flashpoint of less than 140 degrees Fahrenheit (60 degrees Celsius) using the test methods specified in 40 CFR 261.21. (2) Wastewater having a pH less than five or more than 12, or otherwise causing corrosive structural damage to the publicly owned treatment works or equipment. (3) Solid or viscous substances in an amount which will cause obstruction of the flow in the publicly owned treatment works resulting in interference, but in no case solids greater than two inches or five centimeters in any dimension. (4) Pollutants, including oxygen-demanding pollutants (BOD, etc.), released in a discharge at a flow rate and/or pollutant concentration which, either singly or by interaction with other pollutants, will cause interference with the publicly owned treatment works. (5) Heat in amounts which will inhibit biological activity in the treatment plant resulting in interference, but in no case heat in such quantities which causes the temperature at the introduction into the treatment plant to exceed 104 degrees Fahrenheit (40 degrees Celsius). (6) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through. (7) Pollutants which result in the presence of toxic gases, vapors, or fumes within the publicly owned treatment works in a quantity that may cause acute worker health and safety problems. (8) Trucked or hauled pollutants, except at discharge points designated by the city in accordance with section 106-854. (9) Fats, oils and grease in concentrations greater than 500 mg/I, or which violate any other section of this subdivision. (b) Pollutants, substances, or wastewater prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the publicly owned treatment works. Sec. 106-818. - National categorical pretreatment standards. (a) The categorical pretreatment standards found at 40 CFR chapter I, subchapter N, parts 405-471 are incorporated. All existing or new users shall also comply with all applicable pretreatment standards and requirements, including those set forth in 40 CFR 403.6. (b) When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the Control Authority shall impose an alternate limit using the combined wastestream formula in 40 CFR 403.6(e). (c) A user may obtain a variance from a categorical pretreatment standard if the user can prove, pursuant to the procedural and substantive provisions in 40 CFR 403.13, that factors relating to its discharge are fundamentally different from the factors considered by the Environmental Protection Agency when developing the categorical pretreatment standard. (d) A user may obtain a net gross adjustment to a categorical standard in accordance with 40 CFR 403.15. (1) Categorical Pretreatment Standards may be adjusted to reflect the presence of pollutants in the Industrial User's intake water in accordance with this section. Any Industrial User wishing to obtain credit for intake pollutants must make application to the Control Authority. Upon request of the Industrial User, the applicable Standard will be calculated on a "net" basis (i.e., adjusted to reflect credit for pollutants in the intake water) if the requirements of paragraph (2) of this section are met. (2) Criteria (i) Either (i) The applicable categorical Pretreatment Standards contained in 40 CFR subchapter N specifically provide that they shall be applied on a net basis; or (ii) The Industrial User demonstrates that the control system it proposes or uses to meet applicable categorical Pretreatment Standards would, if properly installed and operated, meet the Standards in the absence of pollutants in the intake waters. (ii) Credit for generic pollutants such as biochemical oxygen demand (BOD), total suspended solids (TSS), and oil and grease should not be granted unless the Industrial User demonstrates that the constituents of the generic measure in the User's effluent are substantially similar to the constituents of the generic measure in the intake water or unless appropriate additional limits are placed on the process water pollutants either at the outfall or elsewhere. (iii) Credit shall be granted only to the extent necessary to meet the applicable categorical Pretreatment Standards(s), up to a maximum value equal to the influent value. Additional monitoring may be necessary to determine eligibility for credits and compliance with Standard(s) adjusted under this section. (iv) Credit shall be granted only if the User demonstrates that the intake water is drawn from the same body of water as that into which the POTW discharges. The Control Authority may waive this requirement if it finds that no environmental degradation will result. Sec. 106-819. - State pretreatment standards. State requirements and limitations on discharges to the publicly owned treatment works shall be met by all dischargers which are subject to such standards in any instance in which they are more stringent than federal requirements and limitations or those in this ordinance or any other applicable ordinance. Sec. 106-820. - Local limits. (a) The city has two publicly owned treatment works: POTW#1, known as the Northside Treatment Plant, located at 5645 Burkburnett Road, Wichita Falls, Texas, and POTW #2, known as the Wichita Falls Resource Recovery Facility, located at 1005 River Road, Wichita Falls, Texas. As these two publicly owned treatment works have different capacities, flow characteristics, and receiving waters, the city has developed maximum allowable discharge limits for industrial users for each treatment works. (b) Each industrial discharger will be required to adhere to those limits established at the treatment works receiving its wastewater discharge. The following local limits are established to protect against pass through and interference and to protect sludge quality. These limits are deemed Pretreatment Standards for the purpose of section 307(d) of the Act. Except as provided, no person shall discharge wastewater in excess of the following maximum allowable discharge limits: Wichita Falls Northside Treatment Pollutant Resource Recovery Facility Plant mg/I mg/I Antimony 1.42 0.34 Arsenic 0.89 0.21 Beryllium 0.07 0.47 Cadmium 0.39 0.08 Chromium 6.82 3.48 Copper 6.75 2.30 Cyanide 0.38 0.06 Lead 2.26 0.58 Mercury 0.0083 0.0073 Nickel 1 4.64 1 0.34 Phenols 3.94 0.87 Selenium 0.17 0.02 Silver 0.66 0.66 Zinc 42.54 1.72 (c) Discharge of wastewater containing BOD and/or TSS in concentrations greater than 300 mg/I and fats, oils and grease in concentrations greater than 100 mg/I will be subject to a sewer surcharge at a rate set by the city council to defray the additional costs of treatment for excessive BOD, TSS and fats, oils and grease at the publicly owned treatment works. (d) The surcharge will be an additional charge to the current monthly industrial sewer charge. The surcharge will not be retroactive, but will continue until such time subsequent tests determine that the surcharge requires adjustment. (e) The limits in this section applies to Local Limits only at the point where the wastewater is discharged to the publicly owned treatment works. All concentrations for metallic substances are for total metal unless indicated otherwise. The Control Authority may impose mass limitations in addition to the concentration-based limitations in this section. (f) The Control Authority may impose additional and/or alternative limits by permit on specific individual industrial users. These limits shall be technically based on the allowable loading of the specified pollutant at the appropriate treatment plant. In no case shall these additional and/or alternative limits be less stringent than the above limits, or any applicable federal or state statute. (g) The Control Authority may develop Best Management Practices (BMPs), by ordinance or in individual wastewater discharge permits, to implement Local Limits and the requirements of this ordinance. Sec. 106-821. - City's right of revision. The city reserves the right to establish, by ordinance or in wastewater discharge permits, more stringent standards or requirements on discharges to the publicly owned treatment works. Sec. 106-822. - Dilution. No user shall ever increase the use of process water or in any other way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with a discharge limitation unless expressly authorized by an applicable pretreatment standard or requirement. The Control Authority may impose mass limitations on users who are using dilution to meet applicable pretreatment standards or requirements or in other cases when the imposition of mass limitations is appropriate. Secs. 106-823-106-850. - Reserved. Subdivision III. - Pretreatment Requirements Sec. 106-851. - Pretreatment facilities. Users shall provide necessary wastewater treatment to comply with this ordinance and shall achieve compliance with all applicable categorical pretreatment standards, local limits, and the prohibitions established by this ordinance in subdivision II of this division within the time limitations specified by the Environmental Protection Agency, the state, or the Control Authority, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense. Detailed plans describing such facilities and operating procedures shall be submitted to the Control Authority for review and shall be acceptable to the Control Authority before such facilities are constructed. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the city under this ordinance. Sec. 106-852. - Additional pretreatment measures. (a) Whenever deemed necessary, the Control Authority may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial wastestreams, and meet such other conditions as may be necessary to protect the publicly owned treatment works and determine the user's compliance with the requirements of this ordinance. (b) The Control Authority may require any person discharging into the publicly owned treatment works to install and maintain, on his property and at his expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization. All records, charts, recorded charts or strips, and logs of such controls shall be maintained and provided upon request of the Control Authority. (c) Grease, oil, and sand interceptors or traps shall be provided when, in the opinion of the Control Authority, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil or sand; however, such interceptors or traps shall not be required for residential users. All interception units shall be of a type and capacity approved by the Control Authority and shall be so located to be easily accessible for cleaning and inspection. Such interceptors or traps shall be inspected, cleaned, and repaired regularly, as needed, by the user at his expense. A record of maintenance, repairs, and a log of pumping and waste hauling of contents shall be maintained and provided to the Control Authority upon request. (d) Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter. (e) The Control Authority may require any user to install or have installed at the user's expense a control manhole, of a size and construction approvable by the Control Authority. Additionally, the Control Authority may require the user to construct or have constructed at the user's expense any structures, appurtenances, fences, embankments, rail guards, posts, security system, or any other device with eye bolts, locks, lights, signs, or any other device to ensure the security and safety of Control Authority personnel and sampling equipment. Sec. 106-853. - Accidental discharge and slug control plans. (a) Within one year of being designated as a SIU and at least once every two years thereafter whether each SIU needs a plan or other action to control slug discharges. The Control Authority may require any user to develop, submit for approval, and implement such a plan or take such other action that may be necessary. Alternatively, the Control Authority may develop such a plan for any user. An accidental discharge plan shall address, at a minimum, the following: (1) Description of discharge practices, including nonroutine batch discharges; (2) Description of stored chemicals; (3) Procedures for immediately notifying the Control Authority, other regulatory agencies such as the EPA and the approval authority, and the appropriate wastewater treatment plant of any accidental or slug discharge, as required by section 106-886; and (4) Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include but are not limited to inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants including solvents, and/or measures and equipment for emergency response. The location of floor drains, if present, and any other possible sources of introduction into the waste stream or sanitary sewage system will also be identified. (b) The Control Authority is required to keep records of the activities associated with slug control evaluations and the results are required to be available to the Approval Authority upon request. Sec. 106-854. - Hauled wastewater. The following requirements are in addition to section 106-311 and subdivision III of division 2 of this ordinance: (1) Septic tank waste shall only be introduced into the publicly owned treatment works at locations designated by the publicly owned treatment works and at such times as are established by the publicly owned treatment works. Such waste shall not violate subdivision II of this division or any other requirements established by the city. The Control Authority shall require septic tank waste haulers to obtain wastewater discharge permits. (2) The Control Authority may require haulers of industrial wastewater to obtain wastewater discharge permits. The Control Authority may require generators of hauled industrial wastewater to obtain wastewater discharge permits. The Control Authority may also prohibit the disposal of hauled industrial wastewater. The discharge of hauled industrial wastewater is subject to all other requirements of this ordinance. (3) Industrial wastewater haulers shall discharge loads only at locations designated by the publicly owned treatment works. No load may be discharged without prior consent of the publicly owned treatment works. The publicly owned treatment works or the Control Authority may collect samples of each hauled load to ensure compliance with applicable standards. The publicly owned treatment works or the Control Authority may require the industrial wastewater hauler to provide a waste analysis of any load prior to discharge. (4) Industrial wastewater hauler must provide a trip ticket for every load. (5) The superintendent of the POTW, or his designated representative, may at any time and without prior notice, refuse to allow the discharge of any specific load of hauled wastewater from any particular liquid waste hauler. This refusal may be based upon such criteria as questionable physical characteristics of the hauled wastewater (odor, color, etc.), past history of the manifested liquid waste generator, or any other such information or judgment that the discharge may adversely affect the POTW in any way. In the event of such refusal of discharge, the wastehauler shall provide to the Control Authority within 30 days, a manifest indicating the proper disposal of that load of hauled wastewater. Sec. 106-855. - Disposal of contaminated water from leaking petroleum storage tank sites. (a) After treatment to specified standards, the contaminated water will be placed in a sanitary sewer line where possible. Disposal into the sanitary sewer system will be based on the quality of the water, the peak flow to be placed into the sewer, sewer capacity available, and the availability of sanitary sewer systems. (b) If necessary, the treated water can be placed into the storm drainage system. This disposal method will require an approval authority permit to discharge the treated water into the surface waters of the state. Disposal via the storm drain system must not create a nuisance to the properties between the affected site and the public stream where discharge is permitted by the approval authority. (c) Where it is not possible or feasible to dispose of the treated waters in the sanitary sewer or the disposal by storm drain will create a nuisance effect, and no other disposal methods are available, the city will determine the improvements required in the sanitary or storm drain systems to accept the flow. All improvements will be at the sole expense of the owner of the contaminated site. All improvements must be installed per city standards and procedures, and must be dedicated to the city. (d) All waters from a contaminated site, before disposal into a sanitary sewer, must meet the quality standards of this subdivision with the addition of the following standards for BTEX, lead, and total hydro-carbons: Chemical ug/liter mg/liter Benzene 1,000 1.0 Toluene 1,000 1.0 Ethyl benzene 1,000 1.0 Xylenes 1,000 1.0 Total BTEX 2,000 2.0 Total petroleum Hydrocarbons (TPH) 2.0 Lead (Wichita Falls Resource Recovery Facility POTW) 2.26 Lead (Northside POTW) 1 0.58 1 (e) Prior to disposal of the treated water from the contaminated site, the site owner must present to the Control Authority a copy of the approval authority approved plan for corrective action and, as required, an approval authority permit to discharge to surface waters. The Control Authority will be provided a copy of all laboratory tests conducted to meet the approval authority requirements in the plan for corrective action. The Control Authority may require additional tests beyond those of the approval authority approved plan of corrective action. (f) These procedures apply to either pump-and-treat flows or batch releases of treated waters from contaminated sites. Under no circumstances will a site owner dispose of treated waters from a LPST contaminated site in the city until authorized to do so by the Control Authority. (g) The owner will be required to obtain a permit from the Control Authority. This permit must be renewed annually. The owner must pay an initial permit fee and an annual fee to renew the permit. In addition, each month the owner may pay a fee to defray the cost of reviewing lab results and the results of city-initiated sampling and testing to ensure compliance with both the remedial action plan and the industrial pretreatment ordinance. These costs must be paid until the site is closed by the approval authority and disposal of treated waters has ceased. A statement of the amount of these fees can be obtained from the Control Authority. (h) If the treated water is disposed of in the sanitary sewer, there will be a minimum monthly charge plus the current commodity charge per 1,000 gallons disposed. The amount disposed generally shall be determined by the rated capacity of the pumps in a pump-and-treat system or by the size of the container in a batch disposal system (added). Sec. 106-856. - Fraud and false statements. The reports and other documents required to be submitted or maintained under this ordinance shall be subject to: (1) The provisions of 18 USC 1001 relating to fraud and false statements; (2) The provisions of section 309(c)(4) of the act, as amended, governing false statements, representations, or certifications; and (3) The provisions of section 309(c)(6) of the act regarding responsible corporate officers.

The categorical pretreatment standards applicable to each regulated process. b. The user shall take a minimum of one representative sample to compile that data necessary to comply with the requirements of this subsection. c. Samples should be taken immediately downstream from pretreatment facilities if such exist or immediately downstream from the regulated process if no pretreatment exits. If other wastewaters are mixed with the regulated wastewater prior to pretreatment the User should measure the flows and concentrations necessary to allow use of the combined wastestream formula in 40 CFR 403.6(e) this adjusted limit along with supporting data shall be submitted to the Control Authority. d. Sampling must be performed in accordance with procedures set out in section 106-891. e. The Control Authority may allow the submission of a baseline report which utilizes only historical data so long as the data provides information sufficient to determine the need for industrial pretreatment measures. f. The baseline report shall indicate the time, date, and place of sampling and methods of analysis and shall certify that such sampling and analysis is representative of normal work cycles and expected pollutant discharges to the publicly owned treatment works. g. In cases where the Standard requires compliance with a BMP or pollution prevention alternative, the user shall submit documentation as required by the Control Authority or the applicable standards to determine compliance with the standard. (6) Certification. A statement, reviewed by an authorized representative of the industrial user and certified by a qualified professional, indicating whether pretreatment standards are being met on a consistent basis and, if not, whether additional operation and maintenance (O&M) and/or additional pretreatment is required for the industrial user to meet the pretreatment standards and requirements. (7) Compliance schedule. If additional pretreatment and/or O&M will be required to meet the pretreatment standards, the shortest schedule by which the industrial user will provide such additional treatment and/or O&M. The completion date in this schedule shall not be later than the compliance date established for the applicable pretreatment standard. A compliance schedule pursuant to this section must meet the requirements set out in section 106-882. a. Where the industrial user's categorical pretreatment standard has been modified by a removal allowance (40 CFR 403.7), the combined wastestream formula (40 CFR 403.6(e)), and/or a fundamentally different factors variance (40 CFR 403.13) at the time the user submits the report required by subsection (b) of this section, the information required by subsections (b)(6) and (7) of this section shall pertain to the modified limits. b. If the categorical pretreatment standard is modified by a removal allowance (40 CFR 403.7), the combined wastestream formula (40 CFR 403.6(e)), and/or a fundamentally different factors variance (40 CFR 403.13) after the user submits the report required by subsection (b) of this section, any necessary amendments to the information required by subsections (b)(6) and (7) of this section shall be submitted by the user to the Control Authority within 60 days after the modified limit is approved. c. The Control Authority shall have the authority to set compliance schedules where and when it so deems necessary or if the user's compliance schedule is deemed inadequate by the Control Authority. (8) Signature and certification. All baseline monitoring reports must be signed and certified in accordance with section 106-758. (9) In cases where the Pretreatment Standard requires compliance with a Best Management Practice (BMP) or pollution prevention alternative, the user must submit documentation required by the Control Authority or the Pretreatment Standard necessary to determine the compliance status of the user Sec. 106-882. - Compliance schedule progress reports. The following conditions shall apply to the compliance schedule required by section 106-881(b)(7): (1) The schedule shall contain increments of progress in the form of dates for the commencement and completion of major events leading to the construction and operation of additional pretreatment required for the industrial user to meet the applicable categorical pretreatment standards. Such events include but are not limited to hiring an engineer, completing preliminary plans, completing final plans, executing a contract for major components, commencing construction, completing construction, pretreatment system start-up, first discharge, and beginning and conducting routine operation. (2) No increment referred to in subsection (1)of this section shall exceed nine months. (3) Not later than 14 days following each date in the schedule and the final date for compliance, the industrial user shall submit a progress report to the Control Authority, including, at a minimum, whether or not the user complied with the increment of progress to be met on such date and, if not, the date on which the user expects to comply with this increment of progress, the reason for delay, and the steps being taken by the industrial user to return the construction to the schedule established. (4) In no event shall more than nine months elapse between such progress reports to the Control Authority. Sec. 106-883. - Reports on compliance with categorical pretreatment standard deadline. Within 90 days following the date for final compliance with applicable categorical pretreatment standards or, for a new source, following commencement of the introduction of wastewater into the publicly owned treatment works, any industrial user subject to such pretreatment standards and requirements shall submit to the Control Authority a report containing the information described in section 106-881(b)(4)-(6) & (9). 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 the appropriate sampling period. All compliance reports must be signed and certified in accordance with section 106-758. All sampling will be done in conformance with section 106-891. In cases where the Standard requires compliance with a BMP or pollution prevention alternative, the user shall submit documentation as required by the Control Authority or the applicable standards to determine compliance with the standard. Sec. 106-884. - Periodic compliance reports for categorical industrial users. (a) Any industrial user subject to a categorical standard, after the compliance date of such pretreatment standard or, for a new source, after commencement of the discharge into the publicly owned treatment works, shall submit to the Control Authority on or before July 30th and January 30th, unless required more frequently in the pretreatment standard or by the Control Authority, the Environmental Protection Agency, or the approval authority, a report indicating the nature and concentration of pollutants in the effluent which are limited by such categorical pretreatment standards. In cases where the pretreatment standard requires compliance with a Best Management Practice (BMP) or pollution prevention alternative, the industrial user must submit documentation required by Control Authority or the pretreatment standard necessary to determine the compliance status of the industrial user. In addition, this report shall include a record of measured or estimated average and maximum daily flows for the reporting period for the discharge reported in section 106-881(b)(4) except that the Control Authority may require more detailed reporting of flows. At the discretion of the Control Authority and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the Control Authority may agree to alter the months during which such reports are to be submitted. All compliance reports must be signed and certified in accordance with section 106-758. The samplings may be done in the five months preceding the submittal months; however, they must be done within the same permit year. (b) All wastewater samples must be representative of the 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 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. (c) If a user subject to the reporting requirement in this division monitors any regulated pollutant at the appropriate sampling location more frequently than required by the Control Authority, using the procedures prescribed in section 106-891, the results of this monitoring shall be included in this report. (d) The reports required in this section shall be based upon data obtained through appropriate sampling and analysis performed during the period covered by the report, which data is representative of conditions occurring during the reporting period.

Significant noncategorical industrial users shall submit to the Control Authority at least once every six months, on dates specified by the Control Authority, a description of the nature, concentration, and flow of the pollutants required to be reported to the Control Authority. In cases where compliance with a Best Management Practice (BMP) or pollution prevention alternative is required, the user must submit documentation required by the Control Authority necessary to determine the compliance status of the user. These reports shall be based on sampling and analysis performed in the period covered by the report, and performed in accordance with the techniques described in section 106-891. All periodic compliance reports must be signed and certified in accordance with section 106-758. Sec. 106-886. - Reports of changed conditions. (a) Each user must promptly notify both the Control Authority and the POTW in advance of any planned significant or substantial changes to the user's operations or system which might alter the nature, character, quality, or volume of its wastewater at least 30 days before the change. (b) The Control Authority may require the user to submit such information as may be deemed necessary to evaluate the changed condition, including the submission of a wastewater discharge permit application under section 106-759. (c) The Control Authority may issue a wastewater discharge permit under section 106- 759 or modify an existing wastewater discharge permit under section 106-763 in response to changed conditions or anticipated changed conditions. (d) For purposes of this section, significant changes include but are not limited to flow increases of 20 percent or greater, the discharge of previously unreported pollution, or the addition of any process subject to categorical pretreatment standards. (e) Significant industrial users are required to notify the Control Authority immediately of any changes at its facility affecting the potential for a slug discharge. Sec. 106-887. - Reports of potential problems. (a) If any discharge, including but not limited to accidental discharges, discharges of a nonroutine episodic nature, a noncustomary batch discharge, or any slug discharge, that may cause potential problems for the publicly owned treatment works or for a reportable slug load, the user shall immediately telephone and notify the Control Authority of the incident. This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user. (b) Industrial users shall notify the CA, EPA and state hazardous waste authorities in writing of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR Part 261. (c) Within five days following such discharge, the user shall, unless waived by the Control Authority, submit a detailed written report describing the cause of the discharge and the 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 other liability which may be incurred as a result of damage to the publicly owned treatment works, natural resources, or any other damage to person or property; nor shall such notification relieve the user of any fines, penalties, or other liability which may be imposed pursuant to this division. (d) Every significant industrial user shall permanently post a notice on the user's bulletin board or other prominent place advising employees and contractors whom to call if a discharge described in subsection (a) of this section occurs. Employers shall ensure that all employees and contractors, who may cause such discharge to occur, are advised of the emergency notification. Sec. 106-888. - Reports from other users. (a) All other users required to obtain a wastewater discharge permit shall provide such information and reports to the Control Authority as required by the wastewater discharge permit. (b) All users not required to obtain a wastewater discharge permit shall provide appropriate reports to the Control Authority as the Control Authority may require. Sec. 106-889. - Notice of violation; repeat sampling and reporting. If sampling performed by an industrial user indicates a violation, the user shall notify the Control Authority within 24 hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the Control Authority within 30 days after becoming aware of the violation, except the industrial user is not required to resample if the Control Authority performs sampling at the industrial user: (1) At a frequency of at least once a month; or (2) Between the time when the user performs its initial sampling and the time when the user receives the results of this sampling. Sec. 106-890. - Discharge of hazardous waste. Under this division, all users are prohibited from discharging hazardous waste. Any user who commences the discharge of hazardous waste shall notify the POTW, the EPA Regional Waste Management Division Director, and State hazardous waste authorities, in writing, of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR Part 261. Sec. 106-891. - Sampling and analytical requirements. (a) All pollutant sampling and analyses to be submitted as part of a wastewater discharge permit application or report shall be performed in accordance with the techniques prescribed in 40 CFR 136 and amendments thereto, unless otherwise stated in an applicable categorical pretreatment standard. Where 40 CFR 136 does not contain sampling or analytical techniques for the pollutant in question or where the administrator determines that the 40 CFR 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analysis shall be performed by using validated analytical methods or any other applicable sampling and analytical procedures, including procedures suggested by the publicly owned treatment works or other parties, approved by the administrator. (b) A minimum of four 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 Control Authority 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 grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged. (1) Any report required by the Control Authority must be based upon data obtained through appropriate sampling and analysis performed during the period covered by the report, which data are representative of conditions occurring during the reporting period. The frequency of monitoring shall be of that frequency necessary to assess and assure compliance by Industrial Users with applicable Pretreatment Standards and Requirements. Grab samples must be used for temperature, pH, cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds. For all other pollutants, 24-hour composite samples must be obtained through flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by the Control Authority. Where time-proportional composite sampling or grab sampling is authorized by the Control Authority, the samples must be representative of the Discharge and the decision to allow the alternative sampling must be documented in the Industrial User file for that facility or facilities. Using protocols (including appropriate preservation) specified in 40 CFR part 136 and appropriate EPA guidance, multiple grab samples collected during a 24-hour period may be composited prior to the analysis as follows: For cyanide, total phenols, and sulfides the samples may be composited in the laboratory or in the field; for volatile organics and oil & grease the samples may be composited in the laboratory. Composite samples for other parameters unaffected by the compositing procedures as documented in approved EPA methodologies may be authorized by the Control Authority, as appropriate. (2) All analyses shall be performed in accordance with procedures established by the Administrator pursuant to section 304(h) of the Act and contained in 40 CFR Part 136 and amendments thereto or with any other test procedures approved by the Administrator. (See, §§136.4 and 136.5.) Sampling shall be performed in accordance with the techniques approved by the Administrator. Where 40 CFR part 136 does not include sampling or analytical techniques for the pollutants in question, or where the Administrator determines that the part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed using validated analytical methods or any other sampling and analytical procedures, including procedures suggested by the POTW or other parties, approved by the Administrator. (3) All analyses shall be performed in accordance with procedures established by the Administrator pursuant to section 304(h) of the Act and contained in 40 CFR Part 136 and amendments thereto or with any other test procedures approved by the Administrator. (See, §§136.4 and 136.5.) Sampling shall be performed in accordance with the techniques approved by the Administrator. Where 40 CFR part 136 does not include sampling or analytical techniques for the pollutants in question, or where the Administrator determines that the part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed using validated analytical methods or any other sampling and analytical procedures, including procedures suggested by the POTW or other parties, approved by the Administrator. (4) if any Categorical Industrial User, any non-categorical Significant Industrial User, or any other Industrial User subject to reporting requirements monitors any regulated pollutant at the appropriate sampling location more frequently than required by the Control Authority, using the procedures prescribed in this section, the results of this monitoring shall be included in the report. (5) Non-detectable sampling results may be used only as a demonstration that a pollutant is not present if the EPA approved method from 40 CFR 136 with the lowest minimum detection level for that pollutant was used in the analysis. (c) Submissions of all pollutant analyses shall contain the following: (1) A copy of the laboratory report should be attached. The report should include the following information: a. The name, address, and telephone number of the laboratory performing the analysis. b. The units in which each parameter is reported. c. The method of analysis used (e.g., Environmental Protection Agency 335.1, 3500-Zn-A, etc.). The method must be a technique for wastewater analysis as prescribed in 40 CFR 136. d. The detection limit for each parameter measurement. e. The name, initials, or other such unambiguous identification of the analyzing technician. f. The date each analysis was performed. g. The signature of the laboratory director, or equivalent position. h. Quality control data (e.g., spikes, etc.). i. The results of the analyses. (2) A copy of the chain of custody records should be attached. Each record shall have the following: a. The name and address of the user being sampled. b. The sample container identification number or other such unique, unambiguous identification. c. For a grab sample, the date and time the sample was taken. d. For a composite sampling, the date and time the composite sampler was set up and the date and time the composite sampler was retrieved. e. The exact sampling point of the sample. f. The method of taking the sample (i.e., grab sample, automatic or manual flow- proportioned composite sample, automatic or manual time-proportioned composite sample, etc.). g. The name, title, and signature of the person taking the sample. h. The method of preservation of the sample and the date and time it was preserved, or if no preservation was necessary. i. The date and time dispatched for analysis, the name of the dispatcher, and the method of shipment, if the sample was so dispatched. j. The name of the individual, company, and/or address to which the sample is dispatched. k. The signature of the receiver of the sample, the date and time of its receipt, who it was received from, and its disposition. (d) All wastewater samples must be representative of the 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 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. Sec. 106-892. - Timing. Written reports submitted under this division 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 shall govern. Sec. 106-893. - Recordkeeping. Any CA and any users subject to the reporting requirements of this ordinance shall retain, and make available for inspection and copying, all records of information obtained pursuant to any monitoring activities required by this ordinance, any additional records of information obtained pursuant to monitoring activities undertaken by the User independent of such requirements, and documentation associated with Best Management Practices. Records shall include the date, exact place, method, and time of sampling, and the name of the person(s) taking the samples; the dates analyses were performed; who performed the analyses; the analytical techniques or methods used; and the results of such analyses. These records shall remain available for a period of at least three (3) years. This period shall be automatically extended for the duration of any litigation concerning the User or the Control Authority, or where the User has been specifically notified of a longer retention period by the Control Authority. This requirement shall also apply to the Control Authority. Sec. 106-894. Signatories to Reports All reports and other information requested by the Approval Authority from the City shall be signed by the person and in the manner required by 30 TAC 305.128 (relating to Signatories to Reports). Secs. 106-895-106-920. - Reserved. DIVISION 6. - FEES, RATES AND CHARGES Sec. 106-921. - Pretreatment charges and fees.

(2) Fees for monitoring, inspection, and surveillance procedures, including the cost of collection and analyzing a user's discharge, and reviewing monitoring reports submitted by users. (3) Fees for reviewing and responding to accidental discharge procedures and construction. (4) Fees for filing appeals. (5) Surcharges for BOD and TSS above the value of 300 mg/I, and fats, oils and grease above 100 mg/I. (6) Other fees as the city may deem necessary to carry out the requirements contained in this ordinance. These fees relate solely to the matters covered by this ordinance and are separate from all other fees, fines, and penalties chargeable by the city. Sec. 106-922. - Wastewater discharge permit fees. (a) Wastewater discharge permit fees shall be fixed according to the schedule established by separate ordinance. (b) The rates referenced in subsection (a) of this section are for a permit issued for a period of one year. The Control Authority may prorate the amounts for permits with shorter durations or may multiply the amounts by the appropriate factor for multiyear permits. Unless otherwise designated on the permit, all permits expire at 12:00 midnight on December 31 of the designated year. Sec. 106-923. - Abnormal sewage surcharge. (a) Abnormal sewage shall be defined as sewage containing BOD and/or TSS in concentrations greater than 300 mg/I and/or fats, oils and grease in concentrations greater than 100 mg/I. (b) Any industrial user whose discharge contains abnormal sewage shall be subject to a monthly sewage surcharge payable to the city utility collection division. The surcharge shall be in addition to monthly sewer service charges. Monthly surcharges shall stay in effect until such time as the industrial user demonstrates that it has reduced the abnormality. The reduction must be attained in accordance with section 106-822 and subdivision III of division 4 of this ordinance. The surcharge shall be based on data determined by approved methods of the Environmental Protection Agency (see 40 CFR 136). This data shall be derived from all sampling done at least in the previous six-month period, but this period may be longer if deemed appropriate by the Control Authority. The Control Authority reserves the right to either increase or decrease the surcharge at any time to reflect additional data from sampling. (c) The surcharge for abnormal BOD shall be established by separate ordinance. Any discharge of water or wastewater with a concentration of BOD more than five times the average 24-hour concentration of normal operations of the industrial user shall be prohibited without the prior notification and specific permission of the Control Authority. (d) The surcharge for abnormal TSS shall be established by separate ordinance. Any discharge of water or wastewater with a concentration of TSS more than five times the average 24-hour concentration of normal operations of the industrial user shall be prohibited without the prior notification and specific permission of the Control Authority. (e) The surcharge for abnormal fats, oils and grease shall be established by separate ordinance. Discharge of fats, oils and grease over 500 mg/I is prohibited. (f) Each surcharge shall be assessed separately. For sewage containing more than one abnormal constituent, the surcharges shall be added together. (g) This charge shall be reviewed annually by the Control Authority who may recommend to the city council adjustments as necessary to reflect true costs to the city.
