In September 2009, the Texas Commission on Environmental Quality ( TCEQ ) conducted an audit of the City's Pretreatment Program / Municipal Pollution Prevention Assessment. The findings of the audit identified deficiencies which require the City to: 1. Revise the Industrial Waste Ordinance to comply with current federal regulations; and 2. To align the ordinance with specific components of the Industrial Waste program The proposed ordinance would repeal the existing ordinance Chapter 74, Utilities, Article II, Industrial Waste, Sections 74-36 through 74-58 both inclusive as codified in the City of La Porte Code of Ordinances. Changes to the current ordinance include the addition, deletion, and revision to numerous definitions, the addition and deletion of metal maximum contaminate levels based on current influent and effluent contaminates levels, and modifications to regulatory authority, other language and typographical changes. Additionally, the TCEQ requires a "Funding Resolution" by the governing body to ensure that adequate funding is provided for the operation and maintenance of the City's Pretreatment Program for the protection of the City's treatment works, personnel and the public. Current Significant Industrial Users (SIU's) are aware of the changes and none have expressed concern at this time. The Industrial Waste program is funded in the Wastewater Treatment Division budget through various accounts including an Industrial Waste Inspector, laboratory testing, equipment and supplies, etc. Staff plans to review current fees and return to Council with revised rate plan structure in the future.

Industrial user is not required to resample if the POTW performs sampling between the industrial's initial sampling and when the industrial user receives the results of this sampling. 74-109 k4,94 Notification of the Discharge of Hazardous Waste A. Any industrial 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 CFR Part 261. Such notification must include the name of the hazardous waste set forth in 40 CFR Part 21, the EPA hazardous waste number, and the type of discharge (continuous batch or other). If the industrial user discharges more than ten (10) kilograms of such waste per calendar month to the POTW, the notification shall also contain the following information to the extent such information is known and readily available to the industrial user: 1. An identification of the hazardous constituents contained in the wastes, 2. An estimation of the mass and concentration of such constituents in the wastewater discharged during that calendar month, and 3. An estimation of the mass and constituents in the waste stream expected to be discharged during following twelve(12) months. All notifications must take place no later than one hundred and eighty (180) days after the discharge commences. Any notification under this paragraph need be submitted only once for each hazardous waste discharged. However, notifications of changed discharges must be submitted under SerstieR 74-105 above. The notification requirement in this section does not apply to pollutants already reported under the self-monitoring requirements of SeetieRs 1, " 74- 101, 74-103 and &.4 74-104 above. B.

Compliance Orders When the Director finds that an IU has violated, or continues to violate, any provision of this article, a wastewater discharge permit or order issued hereunder, or any Pretreatment Standard or Requirement, The Director may issue an order to the IU responsible for the discharge directing that the IU come into compliance within a specified time. If the IU does not come into compliance within the time provided, sewer 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 non compliance, including additional self- monitoring and management practices designed to minimize the amount of pollutant discharged to the POTW. A compliance order may not extend the deadline for compliance established for a Pretreatment Standard or Requirement, nor does a compliance order relieve the IU 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 IU. 74-155 ( 1� Cease and Desist Orders When the Director finds that an IU iz=elatin has violated , or continues to violate any provision of a eFEITRance, the useF' wastewater discharge permit, any order issued 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 violations and directing the user to: A. Immediately comply with all requirements, and B. 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. Issuance of a cease and desist order shall not be a prerequisite to taking any other action against the user. 74-156 ( 10.6) Emergency Termination of Services The Director may immediately suspend a user's discharge (after informal notice to the user) whenever such suspension is necessary in order to stop an actual or threatened discharge which reasonably appears to present, or cause an imminent or substantial endangerment to the health, safety and welfare of the 44 public. The Director may also immediately suspend a user's discharge (after notice and opportunity to respond) that threatens to interfere with the operation of the POTW, or which presents or may present an endangerment to the environment. A. 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 prevent or minimize damage to the POTW, its receiving stream, or endangerment to any individuals. The Director shall allow the user to recommence its discharge when the user has demonstrated to the satisfaction of the City that the period of endangerment has passed, unless the termination proceedings set forth in Seel .3 74-153and 74-157 are initiated against the user. B. A IU 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 Director, prior to the date of any show cause or termination hearing under Seetio^,z0.3 74-153 and 1" 74-158.

A. Act of God. The Act of God defense constitutes a statutory affirmative defense ( Texas Water Code 7.2511 in an action brought in municipal or State court. If a person can establish that an event that would otherwise be a violation of a pretreatment ordinance, or a permit issued under the 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. B. An industrial user who wishes to establish an Act of God Affirmative defense shall demonstrate, through relevant evidence that: 1. An event that would otherwise be a violation of a pretreatment ordinance or a permit issued under the ordinance occurred, and the sole cause of the event was an act of God , war, strike, riot or other catastrophe; and 2. The industrial user has submitted the following information to the POTW and the City within 24 hours of becoming aware of the event that would otherwise be a violation of a pretreatment ordinance or a permit issued under the ordinance ( if this information is provided orally, a written submission must be provided within five days), a). a description of the event, and nature and cause of the event; b). the time period of the event, including exact dates and times or , if still continuing, the anticipated time the event is expected to continue; and c), steps being taken or planned to reduce, eliminate and prevent recurrence of the event. C. Burden of proof. In any enforcement proceeding, the industrial user seeking to establish an Act of God affirmative defense shall have burden of proving by a preponderance of the evidence that an event that would otherwise be a violation of a pretreatment ordinance or a permit issued 49 under the ordinance, was caused solely by an act of God , war, strike, riot or other catastrophe. 74-187 (1:3.2 ) General / Specific Prohibitions An industrial user shall have an affirmative defense to an enforcement action except for those circumstances specifies in Secti R 24 A, Q, and u 74-46 A and B and Section 74-64 B of this article of this ^rd—eRanee if it can proven 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: C. A local limit exists for each pollutant discharged and the industrial user was in compliance with each directly prior to, and during , the pass through or interference, or A. 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 4PD€-9--TPDES permit, and in the case of interference, was in compliance with applicable sludge use or disposal requirements 74-188. Bypass A. For the purposes of this Section, (1) Bypass means the intentional diversion of wastewater from any portion of an IU's 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. An IU may allow any bypass to occur which does not cause Pretreatment Standard or Requirements to be violated, but only if it is for essential maintenance to assure efficient operation. C. Bypass Notifications ( 1 ) If an IU knows in advance of the need for a bypass, it shall submit prior notice to the Director, at least ten (10) calendar days before the date of the bypass if possible. 50 ( 2) A IU shall submit oral notice to the Director of an anticipated bypass that exceeds applicable Pretreatment Standards within twenty-four (24) hours from the time it becomes aware of the bypass. A written submission shall also be provided within five (5) calendar days of the time IUs becomes aware of the bypass. The written submission shall contain a description of the bypass and its cause; duration of the bypass, including exact dates and times, and, if the bypass has not been corrected, the anticipated time it is expected to continue; and step taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass. The Director may waive the written report on a case-by-case basis if the oral report has been received within twenty-four (24) hours. D. Bypass ( 1 ) Bypass is prohibited, and the Director may take an enforcement action against an IU for a bypass, unless ( a) The 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 auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment down time. 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 preventative maintenance; and ( c ) The IU submitted notices as required under paragraph C. of the Section. ( 2 ) The Director may approve an anticipated bypass, after considering its adverse effects, if the Director determines that it will meet the three (3) condition listed in paragraph D. (1) of this Section. 51 DIVISION Pqft tr.1, .Is Ell CONTROL OF ADMISSIBLE WASTE 74-196 ( 14.1 ) Interceptors Grease, oil, and sand interceptors shall be provided for the proper handling of liquids wastes containing grease in excessive amounts, or any flammable wastes, sand, and other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwellings. All interceptors shall be a type and capacity approved by the City and shall be located to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be substantially constructed, watertight, and equipped with easily removable covers which when bolted in place, shall be gas tight and watertight.

Within sixty (60) calendar days from the date of this article, any person discharging or desiring to discharge an industrial mixture into the public sewers of the City, or any sewer connected, shall provide and maintain in a suitable, accessible position on the permittee's premises, or such premises occupied by the permittee, a sample well or manhole near the outlet of sewer, drain, pipe, channel, or connection to the sewer or sewage works of the City. Where the installation of a sample well is required by the Director, the IU shall have sixty (60) calendar days to install one after the requirement is written into their permit. Each such manhole or sample well shall be of such construction and design which will prevent infiltration by ground waters and surface waters, and shall be so maintained by the permittee discharging wastes so that any authorized representative, or employee of the City may readily and safely measure the volume and obtain samples of the flow at all times. Plans for construction of the sample well(s) shall be included with the Wastewater Discharge Permit Application, and are subject to approval by the Director. B. Sampling of effluent or discharge may be accomplished manually, or by the use of mechanical equipment, to obtain a composite sample which would be representative of the total effluent. Samples shall be taken at such intervals as to establish the BOD and Total Suspended Solids of the industrial waste for billing purposes, as determined by the City as necessary to maintain a control over the discharges from the Permittee. Additionally, such grab composite samples as deemed necessary by the City shall be taken at such intervals as to establish the concentrations of prohibited discharges and pretreatment standards as specified in this article. The method used in the examination of all industrial wastes to determine BOD and TSS shall be defined in 40 CFR Part 136. 54 DIVISION F.FinahI 15 INDUSTRIAL COST RECOVERY SURCHARGE 74-206 (( 1� A permittee discharging industrial wastes with a BOD exceeding 250 mg/l, or a suspend solids content of greater than 300 mg/I, or both, and meet all Sections, may be accepted for waste water disposal provided that; ( a) The wastes will not cause damage to the collection system; ( b) The wastes will not impair the treatment process. (c) The discharger of the waste enters into a contractual agreement with the Control Authority providing for a surcharge over and beyond the normal sewer rate. The surcharge for industrial discharge is to be calculated as follows: ISS = ( BOD + TSS ) x ( 0 &M cost ) x ( VOL) ; 250 300 ISS = represents Industrial Waste Surcharge in Dollars; BOD represent the Biochemical Oxygen Demand in milligram per liter ( mg/I ). Note: Concentration less than or equal to 250mg/I will be considered a value of zero. TSS represents Suspended Solids in milligram per liter ( mg/I ) Note: Concentration less than zero or equal to 300mg/I will be considered a value of zero. O&M Cost represents operation and maintenance cost of POTW wastewater treatment facility. Note: This cost is determined and updated by the City periodically. VOL represents Volume Discharged in Thousand of Gallons. The volume of waste shall be determined by the same methods used to calculate the normal sewer service charge, or by a sewage flow meter that has been approved by the Director and purchased, installed, and maintained by the permittee. All flow rates, BOD, Total Suspended Solids and 0 & M values used in the determination of the surcharge shall be reevaluated at least on an annual basis. 55 d. The industrial waste surcharges provided for in this ordinance shall be included as a separate item on the regular bill for water and sewer charges and shall be paid monthly in accordance with the existing practices. Surcharges shall be paid at the same time that the sewer charges of the permittee become due and payment for sewer services shall not be accepted without payment also of sewer surcharges. DIVISION SECTION 16 MISCELLANEOUS PROVISIONS 74-211(-1:6.-1-) Pretreatment Charges and Fees The City may adopt reasonable charges and fees for reimbursement of costs of setting up and operating the Pretreatment Program, which may include: A.

When wastewater subject to a categorical Pretreatment Standard is mixed with wastewater not regulated by the same Standard, the Director shall impose an alternate limit in accordance with 40 CFR 403.6(e). B. Once included in its permit, the Industrial User must comply with the equivalent limitations developed in this Section in lieu of the promulgated categorical Standards from which the equivalent limitations were derived. C. Many categorical Pretreatment Standards specify one limit for calculating maximum daily discharge limitations and a second limit for calculating maximum Monthly Average, or 4 -day average, limitations. Where such Standards are being applied, the same production or flow figure shall be used in calculating both the average and the maximum equivalent limitation. D. Any IU operating under a permit incorporating equivalent mass or concentration limits calculated from a production -based Standard shall notify the Director within two (2) business days after the IU has a reasonable basis to know that the production level will significantly change within the next calendar month. Any IU not notifying the Director of such anticipated change will be required to meet the mass or concentration limits in its permit that were based on the original estimate of the long term average production rate. 74-48. State Pretreatment Standards IUs must comply with the state pretreatment standards found in Texas Administrative Code 30, chapters 307 and 315. 74-49. Local Limits A.

The above limits apply at the point where the wastewater is discharged to the POTW. All concentrations for metallic substances are for total metals unless indicated otherwise. The Director may impose mass limitations in addition to the concentration -based limitations above. 74-50. 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 POTW if deemed necessary to comply with the objectives presented in Section 74-36 of this article or the general and specific prohibitions in Section 74-46 of this article. 74-51. Dilution No IU shall ever increase the use of process water, or in any way attempt to dilute a discharge, as partial or complete substitute for adequate treatment to achieve compliance with a discharge limitation unless expressly authorized by the applicable pretreatment standard or requirement. The Director may impose mass limitation on IUs, which are using dilution to meet applicable pretreatment standards or requirements, or in other case when the imposition of mass limitations is appropriate. DIVISION 3 PRETREATMENT OF WASTEWATER 14 74-61. Pretreatment Facilities IUs shall provide necessary wastewater treatment as required to comply with this article and shall achieve compliance with all applicable categorical pretreatment standards, local limits and the prohibitions set out in Section 74-46 above within the time limitations specified by the EPA, the State, or the Director. Any facilities required to pre -treat wastewater to a level acceptable to the Director shall be operated and maintained at the industrial waste IU's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the Director for review, and shall be acceptable to the Director before construction of the facility. The review of such plans and operating procedures will in no way relieve the IU from the responsibility of modifying the facility as necessary to produce an acceptable discharge to the POTW under the provisions of this article. 74-62. Additional Pretreatment Measures A. Whenever deemed necessary, the Director may require IUs to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and /or consolidate points, separate sewage waste -streams and such other conditions as may be necessary to protect the POTW and determine the IU's compliance with the requirements of this article. B. Each permittee discharging into the POTW greater than 120,000 gallons per day or greater than 5 percent of the average daily flow in the POTW, whichever is lesser, shall install and maintain, on their property and at their expense, a suitable storage and flow control facility to insure equalization of flow over a twenty-four (24) hour period. The facility shall have the capacity for at least Two Hundred percent (200%) of the daily discharge volume and shall be equipped with alarms and a rate of discharge controller, the regulation of which shall be directed by the Director. A wastewater discharge permit may be issued solely for flow equalization. C. Grease, oil and sand interceptors shall be provided when, in the opinion of the Director, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil or sand; except that such interceptors shall not be required for residential users. All interceptors units shall be of type and capacity approved by the City and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be cleaned/repaired as needed or more often if CA deems necessary, by the permittee at their own expense. These interceptors shall be subject to the CA's inspections. 15 D. IUs with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detector meter. E. At no time shall two readings on an explosion hazard meter at the point of discharge into the POTW, or at any point in the POTW, be more than five percent (S%) nor any single reading over ten percent (10%) of the lower explosive limit (LEL) of the meter. 74-63. Accidental Discharges /Slue Discharge Control Plan The Director shall evaluate within one year of being designated as an SIU, whether each SIU needs an accidental discharge/slug discharge control plan or other action to control slug discharges. The results of such activities shall be available to the Approval Authority upon request. The Director may require any IU to develop, submit for approval and implement such a plan or take such other action necessary to control Slug Discharges. Alternatively, the Director may develop such a plan for any IU. An accidental discharge/slug discharge control plan shall address, at minimum, the following: A. Description of discharge practices, including non routine batch discharges; B. Description of stored chemicals; C. Procedures for immediately notifying the Director of any accidental or Slug discharge, as required in Section 74-106 of this article; and D. Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading of operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/measures and equipment for emergency response. 16 74-64. Hauled Waste A. Septic domestic tank waste may be introduced into the POTW only at location designated by the Director and at such times as established by the Director. Such waste shall not violate Division 2 of this article or any other requirements established by the City. The Director may require septic tank waste haulers to obtain wastewater discharge permit. B. No hauled in industrial waste may be discharged to the City's sanitary sewer system or the POTW. DIVISION 4. WASTEWATER DISCHARGE PERMIT ELIGIBILITY 74-71. Wastewater Survey When requested by the Director, all IUs must submit information on the nature and characteristics of its wastewater by completing a Wastewater Discharge Survey and a Wastewater Discharge Permit Application thirty (30) calendar days prior to commencing their discharge. The Director is authorized to prepare forms for this purpose and may periodically require IUs to update this information, completing a Wastewater Discharge Survey and Application prior to commencing their discharge. Failure to complete or submit shall be considered a violation of the Industrial Waste Ordinance. 74-72. Wastewater Discharge Permit Requirements A. No SIU shall discharge wastewater into the POTW without obtaining a wastewater discharge permit from the Director, except that a SIU that has filed a timely application pursuant to Section 74-73 of this article may continue to discharge for the time period specified therein. B. The Director may require other Users to obtain wastewater discharge permits as necessary to carry out the purposed of this article. C. Any violation of the terms and conditions of a wastewater discharge permit shall be deemed a violation of this article and subjects the wastewater discharge permittee to the sanctions set out in Division 10 through 12 of this article.

Chronic violations of wastewater discharge limits, defined here as those in which sixty-six percent (66%) or more of all of the measurements taken for the same pollutant parameter taken during a six (6) month period exceed (by any magnitude) a numeric Pretreatment Standard or Requirement, including Instantaneous Limits as defined in Division 2 and 40CFR 403.3(1); B. Technical Review Criteria (TRC) violation, defined here as those in which thirty-three percent (33%) or more of all of the measurements taken for the same pollutant parameter during a six (6) month period equal or exceed the product of the numeric Pretreatment Standard or Requirement including Instantaneous Limits, as defined in Division 2 and 40CFR 403.3(1) multiplied by the applicable criteria TRC (TRC= 1.4 for 36 BOD,TSS, Fats, Oil, and Grease, and 1.2 for all other pollutants except pH); C. Any other violation of a pretreatment Standard or Requirement as defined by 40 CFR 403.3(1) (daily maximum, long-term average, instantaneous limit, or narrative standard) that the Director determines has caused, alone or in combination with other discharges, interference or pass through (including endangering the health of POTW personnel or the general public); D. Any discharge of a pollutant that has caused imminent endangerment to human health, welfare or to the environment or has resulted in the POTW's exercise of its emergency authority under 40 CFR 403.8 (f) (1) (vi) (B) to halt or prevent such a discharge; E. Failure to meet within ninety (90) calendar days after the schedule date, a compliance schedule milestone contained in the IU's permit or enforcement order for starting construction, completing construction, or attaining final compliance; F. Failure to provide, within thirty (30) calendar days after the due date, required reports such as baseline monitoring reports (baseline profile), best management practices (BMP) compliance information, BMP periodic compliance reports, 90 -day compliance reports, periodic self-monitoring reports and reports on compliance with compliance schedules; G. Failure to accurately report noncompliance; H. Any other violation or group of violations, which may include a violation of Best Management Practices, which the Director determines will adversely affect the operation or implementation of the local pretreatment program. DIVISION 10 ADMINISTRATIVE ENFORCEMENT REMEDIES 74-151. Notification of Violation Whenever the Director finds that any IU has violated or continues to violate, any provision this article, their wastewater discharge permit, a pretreatment requirement or any other violation of this article hereunder, the Director or his 37 agent may serve upon that IU a written Notice of Violation (NOV). Within ten (10) business days of the receipt of such notice, an explanation of the violation and plan for the satisfactory correction and prevention thereof, to include specific required action, shall be submitted be the IU to Director. The submission of this plan in no way relieves the IU of liability for any violations occurring before or after the receipt of the Notice of Violation. Nothing in this division shall limit the CA to take any action, including emergency actions, or any other enforcement action, without first issuing Notice of Violation. 74-152. 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 IU responsible for noncompliance. Such orders will include specific action to be taken by the IU to correct the noncompliance within a time period also specified by the order. Consent Orders shall be judicially enforceable. 74-153. Show Cause Hearing The Director may order any IU which cause or contributes to violation(s) of this article, wastewater discharge permits, or orders issued hereunder, or any other pretreatment standard requirement, to appear before the Director and show cause why a proposed enforcement action should not be taken. Notice shall be served on the IU specifying the time and place for the meeting, the proposed enforcement action, the reasons for such action, and request that the IU show cause why this enforcement action should not be taken. The notice of the meeting shall be served personally or by registered or certified mail (return receipt requested) at least five (5) business days prior to the hearing. Such notice may be served on any authorized representative of the IU. Whether or not IUs appear 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 action against the IU. 74-154. Compliance Orders When the Director finds that an IU has violated, or continues to violate, any provision of this article, a wastewater discharge permit or order issued hereunder, or any Pretreatment Standard or Requirement, The Director may issue an order to the IU responsible for the discharge directing that the IU come into compliance within a specified time. If the IU does not come into compliance within the time provided, sewer service may be discontinued unless 38 adequate treatment facilities, devices, or other related appurtenances are installed and properly operated. Compliance orders also may contain other requirements to address the non compliance, including additional self- monitoring and management practices designed to minimize the amount of pollutant discharged to the POTW. A compliance order may not extend the deadline for compliance established for a Pretreatment Standard or Requirement, nor does a compliance order relieve the IU 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 IU. 74-155. Cease and Desist Orders When the Director finds that an IU has violated, or continues to violate, any provision of this article, a wastewater discharge permit, any order issued hereunder, or any other pretreatment standard or requirement, or that the IU's past violations are likely to recur, the Director may issue an order to the IU directing it to cease and desist all violations and directing the IU to: A. Immediately comply with all requirements, and B. Take such appropriate remedial or preventative action as may be needed to properly address a continuing or threatened violations, 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 IU. 74-156. Emergency Termination of Services The Director may immediately suspend a IU's discharge (after informal notice to the IU) whenever such suspension is necessary in order to stop an actual or threatened discharge which reasonably appears to present, or cause an imminent or substantial endangerment to the health, safety and welfare of the public. The Director may also immediately suspend an IU's discharge (after notice and opportunity to respond) that threatens to interfere with the operation of the POTW, or which presents or may present an endangerment to the environment. A. Any IU notified of a suspension of its discharge shall immediately stop or eliminate its contribution. In the event of an IU's failure to immediately comply voluntarily with the suspension order, the Director shall take such steps as deemed necessary, including immediate severance of the 39 sewer connection, to prevent or minimize damage to the POTW, its receiving stream, or endangerment to any individuals. The Director shall allow the IU to recommence its discharge when the IU has demonstrated to the satisfaction of the City that the period of endangerment has passed, unless the termination proceedings set forth in Sections 74-153 and 74-157 of this article are initiated against the IU. B. A IU 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 Director, prior to the date of any show cause or termination hearing under Section 74-153 and 74- 158 of this article. Nothing in this section shall be interpreted as requiring a hearing prior to any emergency suspension under this section. 74-157. Termination of Discharge In addition to those provisions in Section 74-91 of this article, any IU that violates the following conditions of this article, wastewater discharge permit, or orders issued hereunder, is subject to discharge termination. A. Violation of wastewater discharge permit conditions. B. Failure to accurately report the wastewater constituents and characteristics of its discharge. C. Failure to report significant changes in operation or wastewater volume, constituents and characteristics prior to discharge. D. Refusal of reasonable access to the IU's premises for the purpose of inspection, monitoring or sampling. E. Violation of the pretreatment standards in Division 2 of this article. F. When compliance has not been met on any enforcement action listed above that states termination as the next step of enforcement, such IU will be notified of the proposed termination of its discharge and be offered an opportunity to show cause under this Section 74-153 of this article why the proposed action should not be taken. 74-158. Administrative Orders 40 A. When Director finds that an IU has violated, or continues to violate, any provision of this article, wastewater discharge permit or order hereunder, or any Pretreatment Standard or Requirement, Director may fine such IU in an amount not to exceed the maximum fine allowed under State Law. Such fines shall be assessed on a per violation per day basis. In the case of monthly or other long-term average discharge limit, fines shall be assessed for each day during the period of violation. B. Unpaid charges, fines, and penalties after sixty (60) calendar days, the Director may assess an additional penalty of fifteen percent (15%) of the unpaid balance, and interest shall accrue thereafter at a rate of five percent (5%) per month. A lien against the IU property may be sought for unpaid charges, fines and penalties. C. The Director may add the cost of preparing administrative enforcement actions, such as notices and orders to the fine. D. IUs desiring to dispute such fines must file a written request for the Director to reconsider the fine along with full payment of the fine amount within thirty (30) calendar days of being notified of the fine. Where a request has merit, Director may convene a hearing on the matter. In the event the IU appeal is successful, the payment, in addition to any interest accrued thereto, shall be returned to the IU. DIVISION 11 JUDICIAL ENFORCEMENT REMEDIES 74. 166. Iniunctive Relief Whenever the IU has violated a pretreatment standard or requirement, or continues to violate the provisions of this article, wastewater discharge permit or orders issued hereunder, or any other pretreatment requirement, the Director may petition the City of La Porte Municipal Court, through the City's Attorney, for the issuance of a temporary or permanent injunction, as appropriate, which restrains or compels the specific performance of the wastewater discharge permit, order, or other requirement imposed by this article on activities of the IU. Such other action as appropriate for legal and/or equitable relief may also be sought by the City. A petition for injunctive relief need be filed as a prerequisite to taking any other action against an IU. 74.167. Civil Penalties 41 A. Any IU which has violated or continues to violate this article, any order or wastewater discharge permit hereunder, or any other pretreatment standard or requirement shall be liable to the City for a maximum civil penalty of Two Thousand Dollars ($2,000.00) per violation per day. In the case of a monthly or other long-term average discharge limit, penalties shall accrue for each day during the period of the violation. B. The City may recover reasonable attorney's 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 corrective action by the IU, the compliance history of the IU, and other factor as justice requires. D. Filing a suit for civil penalties shall not be a prerequisite for taking any other action against an IU. 74-168. Criminal Prosecution A. Any IU that willfully or negligently violates any provision of this article, any orders, or wastewater discharge permits issued hereunder, or any other pretreatment requirement shall, upon conviction, be guilty of a misdemeanor and, upon conviction, shall be fined a maximum sum of Two Thousand Dollars ($2,000.00). Each day such violation continues shall constitute a separate offense. B. Any IU that willfully or negligently introduces any substance into the POTW which causes personal injury or property damage shall, upon conviction, be guilty of a misdemeanor and, upon conviction, shall be fined a maximum sum of Two Thousand Dollars ($2,000.00).

Any IU knowingly making false statements, representations, or certifications in any application, record, report, plan or other documentation filed, or required to be maintained, pursuant to this article, wastewater discharge permit, or order, or who falsifies, tampers with or knowingly renders inaccurate any monitoring device or method required under this article shall be deemed guilty of a misdemeanor and, upon conviction, be fined a maximum sum of Two Thousand Dollars ($2,000.00). Each day such violation continues shall constitute a separate offense. 42 74-169. Remedies Nonexclusive The provisions in Divisions 9-12 of this article are not exclusive remedies. The City reserves the right to take any, all, or any combination of these actions against a non-compliant IU. Enforcement of pretreatment violations will generally be in accordance with the City's enforcement response plan. However, the City reserves the right to take other action against any IU when the circumstances warrant. Further, the City is empowered to take more enforcement action against any non-compliant IU. These actions may be taken concurrently. DIVISION 12 SUPPLEMENTAL ENFORCEMENT ACTION 74-176. Performance Bonds The Director may decline to reissue a wastewater discharge permit to any IU which has failed to comply with the provisions of this article, any orders, or a previous wastewater discharge permit issued hereunder, unless such IU first files a satisfactory bond, payable to the City, in the sum not to exceed a value determined by the Director to be necessary to achieve consistent compliance. 74-177. Liability Insurance The Director may decline to reissue a wastewater discharge permit to any IU which has failed to comply with the provisions of this article, any orders, or a previous wastewater discharge permit issued hereunder, unless the IU first submits proof that it has obtained financial assurances sufficient to restore or repair damage to the POTW caused by its discharge. 74-178. Water Supply Severance Whenever an IU has violated or continues to violate the provisions of this article, orders, or wastewater discharge permits issued hereunder, water service to the IU may be severed. Service will only be reconnected, at the IU's expense, after it has satisfactorily demonstrated its ability to comply. 74-179. Public Nuisances Any violation of this article, wastewater discharge permits, or orders issued hereunder, is hereby declared a public nuisance and shall be corrected or abated as directed by the Director or designee. Any person(s) creating a public nuisance shall be subject to the provisions of Chapter 34 of this code governing such 43 nuisance, including reimbursing the City for any cost incurred in removing, abating or remedying said nuisance. DIVISION 13 AFFIRMATIVE DEFENSES TO DISCHARGE VIOLATIONS 74-186. Act of God. A. Act of God. The Act of God defense constitutes a statutory affirmative defense [Texas Water Code 7.251] in an action brought in municipal or State court. If a person can establish that an event that would otherwise be a violation of a pretreatment ordinance, or a permit issued under the article, was caused solely by an act of God, war, strike, riot or other catastrophe, the event is not a violation of the article or permit. B. An IU who wishes to establish an Act of God Affirmative defense shall demonstrate, through relevant evidence that: 1. An event that would otherwise be a violation of a pretreatment ordinance or a permit issued under the article occurred, and the sole cause of the event was an act of God, war, strike, riot or other catastrophe; and 2. The IU has submitted the following information to the POTW and the City within twenty-four (24) hours of becoming aware of the event that would otherwise be a violation of a pretreatment ordinance or a permit issued under the article (if this information is provided orally, a written submission must be provided within five (5) calendar days), a) a description of the event, and the nature and cause of the event; b) the time period of the event, including exact dates and times or, if still continuing, the anticipated time the event is expected to continue; and c) steps being taken or planned to reduce, eliminate and prevent recurrence of the event. C. Burden of proof. In any enforcement proceeding, the IU seeking to establish an Act of God affirmative defense shall have burden of proving by a preponderance of the evidence that an event that would otherwise be a violation of a pretreatment ordinance or a permit issued under the 44 article, was caused solely by an act of God, war, strike, riot or other catastrophe. 74-187. General/ Specific Prohibitions An IU shall have an affirmative defense to an enforcement action except for those circumstances specifies in Section 74-46 A and B and Section 74-64 B of this article if it can proven 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 local limit exists for each pollutant discharged and the IU was in compliance with each directly prior to, and during, the pass through or interference, or ■ No local limit exists, but the discharge did not change substantially in nature or constituents from the IU's prior discharge when the City was regularly in compliance with its TPDES permit, and in the case of interference, was in compliance with applicable sludge use or disposal requirements 74-188. Bypass A. For the purposes of this Section, (1) Bypass means the intentional diversion of wastewater from any portion of an IU's 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. An IU may allow any bypass to occur which does not cause Pretreatment Standard or Requirements to be violated, but only if it is for essential maintenance to assure efficient operation. C. Bypass Notifications 45 ( 1 ) If an IU knows in advance of the need for a bypass, it shall submit prior notice to the Director, at least ten (10) calendar days before the date of the bypass if possible. ( 2 ) A IU shall submit oral notice to the Director of an anticipated bypass that exceeds applicable Pretreatment Standards within twenty-four (24) hours from the time it becomes aware of the bypass. A written submission shall also be provided within five (S) calendar days of the time IUs becomes aware of the bypass. The written submission shall contain a description of the bypass and its cause; duration of the bypass, including exact dates and times, and, if the bypass has not been corrected, the anticipated time it is expected to continue; and step taken or planned to reduce, eliminate, and prevent reoccurrence of the bypass. The Director may waive the written report on a case-by-case basis if the oral report has been received within twenty-four (24) hours. D. Bypass ( 1 ) Bypass is prohibited, and the Director may take an enforcement action against an IU for a bypass, unless ( a ) The 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 auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment down time. 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 preventative maintenance; and ( c ) The IU submitted notices as required under paragraph C. of the Section. ( 2 ) The Director may approve an anticipated bypass, after considering its adverse effects, if the Director determines that it will meet the three (3) condition listed in paragraph D. (1) of this Section. DIVISION 14 CONTROL OF ADMISSIBLE WASTE 46 74-196. Interceptors Grease, oil, and sand interceptors shall be provided for the proper handling of liquids wastes containing grease in excessive amounts, or any flammable wastes, sand, and other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwellings. All interceptors shall be a type and capacity approved by the City and shall be located to be readily and easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be substantially constructed, watertight, and equipped with easily removable covers which when bolted in place, shall be gas tight and watertight. Grease and oil and sand interceptors shall be cleaned/maintained and repaired by the person or permittee, at their expense, in continuously efficient operation at all time. These interceptors shall be subject to the City's inspections. Where the CA finds that the pretreatment is not being maintained in a manner that will keep the IU in compliance with this article, the CA may specify required cleaning frequency which will be imposed through their wastewater discharge permit. Restaurants, food service operations and other establishments with commercial kitchen facilities shall have grease interceptors sized and designed by a registered professional engineer in accordance with the City's current adopted plumbing code. 74-197. Sample Wells A. Within sixty (60) calendar days from the date of this article, any person discharging or desiring to discharge an industrial mixture into the public sewers of the City, or any sewer connected, shall provide and maintain in a suitable, accessible position on the permittee's premises, or such premises occupied by the permittee, a sample well or manhole near the outlet of sewer, drain, pipe, channel, or connection to the sewer or sewage works of the City. Where the installation of a sample well is required by the Director, the IU shall have sixty (60) calendar days to install one after the requirement is written into their permit. Each such manhole or sample well shall be of such construction and design which will prevent infiltration by ground waters and surface waters, and shall be so maintained by the permittee discharging wastes so that any authorized representative, or employee of the City may 47 readily and safely measure the volume and obtain samples of the flow at all times. Plans for construction of the sample well(s) shall be included with the Wastewater Discharge Permit Application, and are subject to approval by the Director. B. Sampling of effluent or discharge may be accomplished manually, or by the use of mechanical equipment, to obtain a composite sample which would be representative of the total effluent. Samples shall be taken at such intervals as to establish the BOD and Total Suspended Solids of the industrial waste for billing purposes, as determined by the City as necessary to maintain a control over the discharges from the Permittee. Additionally, such grab composite samples as deemed necessary by the City shall be taken at such intervals as to establish the concentrations of prohibited discharges and pretreatment standards as specified in this article. The method used in the examination of all industrial wastes to determine BOD and TSS shall be defined in 40 CFR Part 136. DIVISION 15 INDUSTRIAL COST RECOVERY SURCHARGE 74-206. Industrial Cost Recovery. A permittee discharging industrial wastes with a BOD exceeding 250 mg/l, or a TSS content of greater than 300 mg/l, or both, and meet all other applicable requirements, including those established under this article, may be accepted for waste water disposal provided that; ( a) The wastes will not cause damage to the collection system; ( b) The wastes will not impair the treatment process. ( c) The discharger of the waste enters into a contractual agreement with the CA, via their wastewater discharge permit, providing for a surcharge over and beyond the normal sewer rate. The industrial waste surcharge for industrial discharge is to be calculated as follows: IWS = ( BOD + TSS ) x (O &M cost ) x ( VOL) ; 250 300 IWS = represents Industrial Waste Surcharge in Dollars; BOD = represents the Biochemical Oxygen Demand in milligram per liter (mg/1). Note: Concentration less than or equal to 250 mg/I will be considered a value of zero. 48 TSS = represents Total Suspended Solids or Suspended Solids in milligram per liter (mg/1) Note: Concentration less than zero or equal to 300mg/I will be considered a value of zero. O&M = Cost represents operation and maintenance cost of POTW wastewater treatment facility. Note: This cost is determined and updated by the City periodically. VOL = represents Volume Discharged in Thousand of Gallons. The volume of waste shall be determined by the same methods used to calculate the normal sewer service charge, or by a sewage flow meter that has been approved by the Director and purchased, installed, and maintained by the permittee. All flow rates, BOD, Total Suspended Solids and O & M values used in the determination of the industrial waste surcharge shall be reevaluated at least on an annual basis. ( d) The industrial waste surcharges provided for in this article shall be included as a separate item on the regular bill for water and sewer charges and shall be paid monthly in accordance with the existing practices. Surcharges shall be paid at the same time that the sewer charges of the permittee become due and payment for sewer services shall not be accepted without payment also of industrial waste surcharges. DIVISION 16 MISCELLANEOUS PROVISIONS 74-211. Pretreatment Charges and Fees The City may adopt reasonable charges and fees for reimbursement of costs of setting up and operating the Industrial Waste Pretreatment Program, which may include: A. Fees for wastewater discharge permit applications including the cost of processing such applications; B. Fees for monitoring, inspection, and surveillance procedures including the cost of collection and analyzing an IU's discharge, and reviewing monitoring reports submitted by IUs; 49 C Fees for reviewing construction plans and responding to accidental discharges; D. Fees for filing appeals; E. Other fees as the City may deem necessary to carry out the requirements of its' industrial waste pretreatment program. These fees related solely to the matters covered by this article and are separate from all other fees, fines and penalties chargeable by the City. Section 2.

Daily average flow determination for intermittent discharges shall consist of a minimum of three flow determinations on days of discharge. c. Daily maximum flow - the highest total flow for any 24-hour period in a calendar month. d. Instantaneous flow - the measured flow during the minimum time required to interpret the flow measuring device. e. 2 -hour peak flow (domestic wastewater treatment plants) - the maximum flow sustained for a two-hour period during the period of daily discharge. The average of multiple measurements of instantaneous maximum flow within a two-hour period may be used to calculate the 2 -hour peak flow. f. Maximum 2 -hour peak flow (domestic wastewater treatment plants) - the highest 2 -hour peak flow for any 24-hour period in a calendar month. 2. Concentration Measurements a. Daily average concentration - the arithmetic average of all effluent samples, composite or grab as required by this permit, within a period of one calendar month, consisting of at least four separate representative measurements. i. For domestic wastewater treatment plants - When four samples are not available in a calendar month, the arithmetic average (weighted by flow) of all values in the previous four consecutive month period consisting of at least four measurements shall be utilized as the daily average concentration. Page 3 City of La Porte TPDES Permit No. WQoolozoboox ii, For all other wastewater treatment plants - When four samples are not available in a calendar month, the arithmetic average (weighted by flow) of all values taken during the month shall be utilized as the daily average concentration. b.. 7 -day average concentration - the arithmetic average of all effluent samples, composite or grab as required by this permit, within a period of one calendar week, Sunday through Saturday. c.

Daily discharge - the discharge of a pollutant measured during a calendar day or any 24- hour period that reasonably represents the calendar day for purposes of sampling. For pollutants with limitations expressed in terms of mass, the daily discharge is calculated as the total mass of the pollutant discharged over the sampling day. For pollutants with limitations expressed in other units of measurement, the daily discharge is calculated as the average measurement of the pollutant over the sampling day. The daily discharge determination of concentration made using a composite sample shall be the concentration of the composite sample. When grab samples are used, the daily discharge determination of concentration shall be the arithmetic average (weighted by flow value) of all samples collected during that day. e. Bacteria concentration (E. coli or Enterococci) - Colony Forming Units (CFU) or Most Probable Number (MPN) of bacteria per loo milliliters effluent. The daily average bacteria concentration is a geometric mean of the values for the effluent samples collected in a calendar month. The geometric mean shall be determined by calculating the nth root of the product of all measurements made in a calendar month, where n equals the number of measurements made; or, computed as the antilogarithm of the arithmetic mean of the logarithms of all measurements made in a calendar month. For any measurement of bacteria equaling zero, a substituted value of one shall be made for input into either computation method. If specified, the 7 -day average for bacteria is the geometric mean of the values.for all effluent samples collected during a calendar week. f. Daily average loading (lbs/day) - the arithmetic average of all daily discharge loading calculations during a period of one calendar month. These calculations must be made for each day of the month that a parameter is analyzed. The daily discharge, in terms of mass (lbs/day), is calculated as (Flow, MGD x Concentration; mg/l x $.34)• g. Daily maximum loading (lbs/day) - the highest daily discharge, in terms of mass . (lbs/day), within a period of one calendar month. 3. Sample Type a. Composite sample - For domestic wastewater, a composite sample is a sample made lip of a minimum of three effluent portions collected in a continuous 24-hour period or during the period of daily discharge if less than 24 hours, and combined in volumes proportional to flow, and collected at the intervals required by 3o. TAC § 319.9 (a). For industrial wastewater, a composite sample is a sample made up. of a minimum of three effluent portions collected in a continuous 24-hour period or during the period of daily discharge if less than 24 hours, and combined in volumes proportional to flow, and collected at the intervals required by 3o TAC § 319.9 (b). Page 4 City of La Porte TPDES Permit No. WQoo1o2o6001 b. Grab sample - an individual sample collected in less than 15 minutes. 4. Treatment Facility (facility) - wastewater facilities used in the conveyance, storage, treatment, recycling, reclamation and/or disposal of domestic sewage, industrial wastes; agricultural wastes, recreational wastes, or other wastes including sludge handling or disposal facilities under the jurisdiction of the Commission, 5. The term "sewage sludge" is defined as solid, semi-solid, or liquid residue generated during the treatment of domestic sewage in 3o TAC Chapter 312. This includes the solids that have not been classified as hazardous waste separated from wastewater by unit processes. 6. Bypass - the intentional diversion of a waste stream from any portion of a treatment facility. MONITORING AND REPORTING REQUIREMENTS 1.

To request a less frequent schedule, the permittee shall submit a written request to the TCEQ Wastewater Permitting Section (MC 148) for each phase that includes a different monitoring frequency. The request must contain all of the reported bacteria values (Daily Avg. and Daily Max/Single Grab) for the twelve consecutive months immediately prior to the request. If the Executive Director finds that a less frequent measurement schedule is protective of human health and the environment, the permittee may be given a less frequent measurement schedule. For this permit, 1/week may be reduced to 2/month. A violation of any bacteria limit by a facility that has been granted a less frequent measurement schedule will Page 31 City of La Porte TPDES Permit No. WQ00102o6001 require the permittee to return to the standard frequency schedule and submit written notice to the TCEQ Wastewater Permitting Section (MC 148). The permittee may not apply for another reduction in measurement frequency for at least 24 months from the date of the last violation. The Executive Director may establish a more frequent measurement schedule if necessary to protect human health or the environment. 8. A certified operator shall inspect the facility daily and maintain at the plant site a record of these inspections. These records shall be available at the plant site for inspection by authorized representatives of the commission for at least three years. g. Permit compliance/noncompliance determinations will be based on the effluent limitations contained in this permit with consideration given to the Minimum Analytical Level (MAL) for the parameters specified as follows. Test methods utilized shall be sensitive enough to demonstrate compliance with the permit effluent limitations. Parameter MAL (mg/1) Total Copper 0.010 Total Nickel 0.010 Total Zinc 0.005 When an analysis of an effluent sample for any of the parameters listed above indicates no detectable levels above the MAL and the test method detection level is as sensitive as the specified MAL, a value of zero (o) shall be used for that measurement when determining calculations and reporting requirements for the self reporting form. This applies to determinations of daily maximum concentration, calculations of loading and daily averages, and other reportable results. When a reported value is zero (o) based on this MAL provision, the permittee shall submit the following statement with the self -reporting form either as a separate attachment to the form or as a statement in the comments section of the form. "The reported value(s) of zero (o) for [list parameter(s)] on the self -reporting form for [monitoring period date range] is based on the following conditions: 1) the analytical method used had a method detection level as sensitive as the MAL specified in the permit, and 2) the analytical results contained no detectable levels above the specified MAL." When an analysis of an effluent sample for a parameter indicates no detectable levels and the test method detection level is not as sensitive as the MAL specified in the permit, or an MAL is not specified in the permit for that parameter, the level of detection achieved shall be used for that measurement when determining calculations and reporting requirements for the self -reporting form. A zero (o) may not be used. Page 32 City of La Porte TPDES Permit No. WQ00102o6o01 CONTRIBUTING INDUSTRIES AND PRETREATMENT REQUIREMENTS r. The permittee shall operate an industrial pretreatment program in accordance with Sections 4020)(8) and (b)(9) of the Clean Water Act, the General Pretreatment Regulations (40 CFR Part 403) and the approved POTW pretreatment program submitted by the permittee. The pretreatment program was approved on November 17, 2004, and modified on January 22, 20314 (Streamlining Rule). The POTW pretreatment program is hereby incorporated by reference and shall be implemented in a manner consistent with the following requirements: a, Industrial user (IU) information shall be kept current according to 40 CFR §§403.8(f)(2)(i) and (ii) and updated at a frequency set forth in the approved pretreatment program to reflect accurate characterization of all IUs; b. The frequency and nature of IU compliance monitoring activities by the permittee shall be consistent with the approved POTW pretreatment program and commensurate with the character, consistency, and volume of waste. The permittee is required to inspect and sample the effluent from each significant industrial user (SIU) at least once per year, except as specified in 40 CFR §403.8 (f)(2)(v). This is in addition to any industrial self-monitoring activities; C. The permittee shall enforce and obtain remedies for IU noncompliance with applicable pretreatment standards and requirements and the approved POTW pretreatment program; d. The permittee shall control through permit, order, or similar means, the contribution to the POTW by each IU to ensure compliance with applicable pretreatment standards and requirements and the approved POTW pretreatment program. In the case of SIUs (identified as significant under 40 CFR §403.3 (v)), this control shall be achieved through individual permits or general control mechanisms, in accordance with 40 CFR §403.8(f)(1)(iii). Both individual and general control mechanisms must be enforceable and contain, at a minimum, the following conditions: (1) Statement of duration (in no case more than five years); (2) Statement of non -transferability without, at a minimum, prior notification to the POTW and provision of a copy of the existing control mechanism to the new owner or operator; (3) Effluent limits, which may include enforceable best management practices (BMPs), based on applicable general pretreatment standards, categorical pretreatment standards, local limits, and State and local law; (4) Self-monitoring, sampling, reporting, notification and record keeping requirements, identification of the pollutants to be monitored (including, if applicable, the process for seeking a waiver for a pollutant neither present nor expected to be present in the IU's discharge in accordance with 40 CFR §403•12(e)(2), or a specific waived pollutant in the case of an individual control mechanism), sampling location, sampling frequency, and sample type, based on the applicable general pretreatment standards in 40 CFR Part 403, categorical pretreatment standards, local limits, and State and local law; Page 33 City of La Porte TPDES Permit No. WQ00102o6001 (5) Statement of applicable civil and criminal penalties for violation of pretreatment standards and requirements, and any applicable compliance schedule. Such schedules may not extend the compliance date beyond federal deadlines; and, (6) Requirements to control slug discharges, if determined by the POTW to be necessary. C. For those IUs who are covered by a general control mechanism, in order to implement 40 CFR §403.8(f)(1)(iii)(A)(2), a monitoring waiver for a pollutant neither present nor expected to be present in the IU's discharge is not effective in the general control mechanism until after the POTW has provided written notice to the SIU that such a waiver request has been granted in accordance with 40 CFR §403.12(e)(2). f. The permittee shall evaluate, whether each SIU needs a plan or other action to control slug discharges, in accordance with 40 CFR §403.8(f)(2)(vi). If the POTW decides that a slug control plan is needed, the plan shall contain at least the minimum elements required in 40 CFR §403.8(f)(2)(vi); g. The permittee shall provide adequate staff, equipment, and support capabilities to carry out all elements of the pretreatment program; and, h. The approved program shall not be modified. by the permittee without the prior approval of the Executive Director, according to 40 CFR §403.18. 2. The permittee is under a continuing duty to: establish and enforce specific local limits to implement the provisions of 40 CFR. §403.5, develop and enforce local limits as necessary, and modify the approved pretreatment program as necessary to comply with federal, state and local law, as amended. The permittee may develop BMPs to implement paragraphs 40 CFR §§403.5(c)(1) and (c)(2). Such BMPs shall be considered local limits and pretreatment standards. The permittee is required to effectively enforce such limits and to modify their pretreatment program, including the Legal Authority, Enforcement Response Plan and/or Standard Operating Procedures, if required by the Executive Director to reflect changing conditions at the POTW. Substantial modifications will be approved in accordance with 40 CFR §403.18, and modifications will become effective upon approval by the Executive Director in accordance with 40 CFR §403.18. If after review of the substantial modification submission, the Executive Director determines that the submission does not comply with applicable requirements, including 40 CFR §§403.8 and 403.9, the Executive Director will notify the permittee. According to 40 CFR §403.11(c), the notification will include suggested modifications to bring the substantial modification submission into compliance with applicable requirements, including 40 CFR §§403.8(b) and (f), and 40 CFR §403.9(b). In such a case, revised information will be necessary for the Executive Director to make a determination on whether to approve or deny the permittee's substantial modification submission. Upon approval by the Executive Director of the substantial modification to this approved POTW pretreatment program, the requirement to develop and enforce specific prohibitions and/or limits to implement the prohibitions and limits set forth in 40 CFR §§403.5 (a)(1), (b), (c)(1) and (3), and (d) is a condition of this permit. The specific prohibitions set out in 40 CFR §403.5(U) shall be enforced by the permittee unless modified under this provision. Page 34 City of La Porte TPDES Permit No. WQ00102o6001 3. The permittee shall analyze the treatment facility influent and effluent for the presence of the toxic pollutants listed in the Texas Surface Water Quality Standards 13o TAC Chapter 3071, and in 40 CFR Part 122 Appendix D Table II at least once per year and the toxic pollutants in Table III at least once per three months. If, based upon information available to the permittee, there is reason to suspect the presence of any toxic or hazardous pollutant listed in 40 CFR Part 122 Appendix D Table V, or any other pollutant, known or suspected to adversely affect treatment plant operation, receiving water quality, or solids disposal procedures, analysis for those pollutants shall be performed at least once per three months on both the influent and the effluent. The influent and effluent samples collected shall be composite samples consisting of at least 12 aliquots collected at approximately equal .intervals over a representative 24 hour period and composited according to flow. Sampling and analytical procedures shall be in accordance with guidelines established. in 40 CFR Part 136, as amended; as approved by the EPA through the application for alternate test procedures; or as suggested in Tables 8 and 9 of the Procedures to Implement the Texas Surface Water Quality. Standards, January 2003, as amended and adopted by the TCEQ. The effluent samples shall be analyzed to the minimum analytical level (MAL). Where composite samples are inappropriate, due to sampling, holding time, or analytical constraints, at least four (4) grab samples, taken at equal intervals over a representative 24 hour period, shall be taken. 4. The permittee shall prepare annually a list of IUs which during the preceding twelve (12) months were in significant noncompliance (SNC) with applicable pretreatment requirements. For the purposes of this section of the permit, "Contributing Industries and Pretreatment Requirements", SNC shall be determined based upon the more stringent of either criteria established at 40 CFR §403.8(f)(2)(viii) [rev.1%4/o5] or criteria established in the approved POTW pretreatment program.

These additional effluent concentrations are 32%, 42%, 54%, 74%, and gg% effluent. The critical dilution, defined as gg% effluent, is the effluent concentration representative of the proportion of effluent in the receiving water during critical low flow or critical mixing conditions. d. This permit may be amended to require a WET limit, a Chemical -Specific (CS) limit, a Best Management Practice (BMP), or other appropriate actions to address toxicity. The permittee may be required to conduct a Toxicity Reduction Evaluation after multiple toxic events. C. Testing Frequency Reduction 1) If none of the first four consecutive quarterly tests demonstrates significant toxicity, the permittee may submit this information in writing and, upon approval, reduce the testing frequency to once per six months for the invertebrate test species and once per year for the vertebrate test Page 51 City of La Porte TPDES Permit No. WQ00102o600i species. 2) If one or more of the first four consecutive quarterly tests demonstrates significant toxicity, the permittee shall continue quarterly testing for that species until the permit is reissued. If a testing frequency reduction had been previously granted and a subsequent test demonstrates significant toxicity, the permittee will resume a quarterly testing frequency for that species until the permit is reissued. 2. Required Toxici . Testing Conditions a. Test Acceptance - The permittee shall repeat any toxicity test, including the control and all effluent dilutions, which fails to meet any of the following criteria: 1) a control mean survival of 8o% or greater; 2) a control mean dry weight of surviving mysid shrimp of 0.20 mg or greater; 3) a control mean dry weight for surviving unpreserved inland silverside of 0.50'mg or greater and 0.43 mg or greater for surviving preserved inland silverside. 4} a control Coefficient of Variation percent (CV%) between replicates of 40 or less in the growth and survival tests. 5) a critical dilution CV% of 40 or less in the growth and survival endpoints for either growth and survival test. However, if statistically significant lethal or nonlethal effects are exhibited at the critical dilution, a CV% greater than 40 shall not invalidate the test. 6) a Percent Minimum Significant Difference of 37 or less for mysid shrimp growth; 7) a Percent Minimum Significant Difference of 28 or less for inland silverside growth. b. Statistical Interpretation 1) For the mysid shrimp and the inland silverside larval survival and growth tests, the statistical analyses used to determine if there is a significant difference between the control and an effluent dilution shall be in accordance with the manual referenced above, or its most recent update. 2) The permittee is responsible for reviewing test concentration -response relationships to ensure that calculated test -results are interpreted and reported correctly. The EPA manual, "Method Guidance and Recommendation for Whole Effluent Toxicity (WET) Testing (40 CFR Part 136)" (EPA 821-B-oo-004), provides guidance on determining the validity of test results. Page 92 City of La Porte TPDES Permit No. WQ00102o6001 3) If significant lethality is demonstrated (that is, there is a statistically significant difference in survival at the critical dilution when compared to the control), the conditions of test acceptability are met, and the survival of the test organisms are equal to or greater than 8o% in the critical dilution and all dilutions below that, then the permittee shall report a survival No Observed Effect Concentration (NOEL) of not less than the critical dilution for the reporting requirements. 4) The NOEL is defined as the greatest effluent dilution at which no significant effect is demonstrated. The Lowest Observed Effect Concentration (LOEC) is defined as the lowest effluent dilution at which a significant effect is demonstrated. A significant effect is herein defined as a statistically significant difference at the 95% confidence level between the survival, reproduction, or growth of the test organism(s) in a specified effluent dilution compared to the survival, reproduction, or growth of the test organism(s) in the control (o% effluent). 5) The use of NOECs and LOECs assumes tither a monotonic (continuous) concentration -response relationship or a threshold model of the concentration -response relationship. For any test result that demonstrates a non -monotonic (non -continuous) response, the NOEC should be determined based on the guidance manual referenced in Item 2 above. 6) Pursuant to the responsibility assigned to the permittee in Part 2.b.2), test results that demonstrate anon -monotonic (non -continuous) concentration -response relationship may be submitted, prior to the due date, for technical review. The above -referenced guidance manual will be used when maldng a determination of test acceptability. 7) Staff will review test results for consistency with rules, procedures, and permit requirements. C. Dilution Water Because of a recent demonstration of toxicity in the receiving water, the permittee shall use synthetic dilution water in all toxicity tests. d. Samples and Composites 1) The permittee shall collect a minimum of three composite samples from Outfall oo1. The second and third composite samples will be used for the renewal of the dilution concentrations for each toxicity test. 2) The permittee shall collect the composite samples such that the samples are representative of any periodic episodeof chlorination, biocide usage, or other potentially toxic substance discharged on an intermittent basis. 3) The permittee shall initiate the toxicity tests within 36 hours after collection of the last portion of the first composite sample. The holding time for any subsequent composite sample shall not exceed 72 hours. Page 53 City of La Porte TPDES Permit No. WQ00102o6001 Samples shall be maintained at a temperature of o-6 degrees Centigrade during collection, shipping, and storage. 4). If Outfall oo1 ceases discharging during the collection of effluent samples, the requirements for the minimum number of effluent samples, the minimum numbers of effluent portions, and the sample holding time, are waived during that sampling period. However, the permittee must have collected an effluent composite sample volume sufficient to complete the required toxicity tests with renewal of the effluent. When possible, the effluent samples used for the toxicity tests shall be collected on separate days if the discharge occurs over multiple days. The sample collection duration and the static renewal protocol associated with the abbreviated sample collection must be documented in the full report. 5) The effluent samples shall not be dechlorinated after sample collection. 3. Reporting All reports, tables, plans, summaries, and related correspondence required in any Part of this Section shall be submitted to the attention of the Standards Implementation Team (MC r5o) of the Water Quality Division. a. The permittee shall prepare a full report of the results of all tests conducted in accordance with the manual referenced above, or its most recent update, for every valid and invalid toxicity test initiated whether carried to completion or not. b. The permittee shall routinely report the results. of each biomonitoring test on the Table 1 forms provided with this permit. 1} Annual biomonitoring test results are due on or before January 2oth for biomonitoring conducted during the previous 12 month period. 2) Semiannual biomonitoring test results are due on or before July 2oth and January zoth for biomonitoring conducted during the previous 6 month period. 3) Quarterly biomonitoring test results are due on or before April loth, July loth, October loth, and January 2oth, for biomonitoring conducted during the previous calendar quarter. 4} Monthly biomonitoring test results are due on or before the loth day of the month following sampling.

Persistent Toxicity The requirements of this Part apply only when a test demonstrates a significant effect at the critical dilution. A significant effect is defined as a statistically significant difference, at the 959,6' confidence level, between a specified endpoint (survival or growth) of the test organism in a specified effluent dilution when compared to the specified endpoint of the test organism in the control. Significant lethality is defined as a statistically significant difference in survival at the critical dilution when compared to the survival of the test organism in the control. ,Significant sublethality is defined as a statistically significant difference in growth at the critical dilution when compared to the growth of the test organism in the control. a. The permittee shall conduct a total of 2 additional tests (retests) for any species that demonstrates a significant effect (lethal or sublethal) at the critical dilution. The two retests shall be conducted monthly during the next two consecutive months. The permittee shall not substitute either of the two retests in lieu of routine toxicity testing. All reports shall be submitted within 20 days of test completion. Test completion is defined as the last day of the test. Page 55 City of La Porte TPDES Permit No. WQ00102o600t b. If the retests are performed due to a demonstration of significant lethality, and one or both of the two retests specified in item 4.a, demonstrates significant lethality, the permittee shall initiate the TRE requirements as specified in Part 5. The provisions of item 4.a. are suspended upon completion of the two retests and submittal of the TRE Action Plan and Schedule defined in Part 5. If neither test demonstrates significant lethality and the permittee is testing under the reduced testing frequency provision of Part te., the permittee shall return to a quarterly testing frequency for that species. C. If the two retests are performed due to a demonstration of significant sublethality, and one or both of the two retests specified in item 4.a. demonstrates significant lethality, the permittee shall again perform two retests as stipulated in item 4.a. d. If the two retests are performed due to a demonstration of significant sublethality, and neither test demonstratessignificant lethality, the permittee shall continue testing at the quarterly frequency. e. Regardless of whether retesting for lethal or sublethal effects or a combination of the two, no more than one retest per month is required for a species. 5. Toxicity Reduction Evaluation a. Within 45 days of the retest that demonstrates significant lethality, or within 45 days of being so instructed due to multiple toxic events, the permittee shall submit a General Outline for initiating a Toxicity Reduction Evaluation (TRE). The outline shall include, but not be limited to, a description of project personnel, a schedule for obtaining consultants (if needed), a discussion of influent and effluent data available for review, a sampling and analytical schedule, and a proposed TRE initiation date. b. Within go days of the retest that demonstrates significant lethality, or within go days of being so instructed due to .multiple toxic events, the permittee shall submit a TRE Action Plan and Schedule for conducting a TRE. The plan shall specify the approach and methodology to be used in performing the TRE. A TRE is a step -wise investigation combining toxicity testing with physical and chemical analysis to determine actions necessary to eliminate or reduce effluent toxicity to a level not effecting significant lethality at the critical dilution. The TRE Action Plan shall lead to the successful elimination of significant lethality for both test species defined in item 1,b. As a minimum, the TRE Action Plan shall include the following: 1) Specific Activities - The TRE Action Plan shall specify the approach the permittee intends to utilize in conducting the TRE, including toxicity characterizations, identifications, confirmations, source evaluations, treatability studies, and alternative approaches. When conducting characterization analyses, the permittee shall perform multiple characterizations and follow the procedures specified in the document entitled, "Methods for Aquatic Toxicity Identification Evaluations: Phase I Toxicity Characterization Procedures" (EPA/600/6-91/003), or alternate Page 56 City of La Porte TPDES Permit No. WQ00102o600i procedures. The permittee shall perform multiple. identifications and follow the methods specified in the documents entitled, "Methods for Aquatic Toxicity Identification Evaluations, Phase II Toxicity Identification Procedures for Samples Exhibiting Acute and Chronic Toxicity" (EPA/600/R-92/o8o) and "Methods for Aquatic Toxicity Identification Evaluations, Phase III Toxicity Confirmation Procedures for Samples Exhibiting Acute and Chronic Toxicity" (EPA/600/R-92/o81). All characterization, identification, and confirmation tests shall be conducted in an orderly and logical progression; 2) Sampling Plan - The TRE Action Plan should describe sampling locations, methods, holding times, chain of custody, and preservation techniques. The effluent sample volume collected for all tests shall be adequate to perform the toxicity characterization/ identification/ confirmation procedures, and chemical -specific analyses when the toxicity tests show significant lethality. Where the permittee has identified or suspects specific pollutant(s) and source(s) of effluent toxicity, the permittee shall conduct, concurrent with toxicity testing, chemical -specific analyses for the identified and suspected pollutant(s) and source(s) of effluent toxicity; 3) Quality Assurance Plan - The TRE Action Plan should address record keeping and data evaluation, calibration and standardization, baseline tests, system blanks, controls, duplicates, spikes, toxicity persistence in the samples, randomization, reference toxicant control charts, as well as mechanisms to detect artifactual toxicity; and 4) Project Organization - The TRE Action Plan should describe the project. staff, project manager, consulting engineering services (where applicable), consulting analytical and toxicological services, etc. C. Within 3o days of submittal of the TRE Action Plan and Schedule, the permittee shall implement the TRE with due diligence. d. The permittee shall submit quarterly TRE Activities Reports concerning the progress of the TRE. The quarterly reports are due on or before April loth, July 2oth, October loth, and January loth. The report shall detail information regarding the TRE activities including: 1) results and interpretation of any chemical -specific analyses for the identified and suspected pollutant(s) performed during the quarter; 2) results and interpretation of any characterization, identification, and confirmation tests performed during the quarter; 3) any data and substantiating documentation which identifies the pollutant(s) and source(s) of effluent toxicity; 4) results of any studies/evaluations concerning the treatability of the facility's effluent toxicity; 5) any data which identifies effluent toxicity control mechanisms that will Page 57 City of La Porte TPDES Permit No. WQ00102o600l reduce effluent toxicity to the level necessary to meet no significant lethality at the critical dilution; and 6) any changes to the initial TRE Plan and Schedule that are believed necessary as a result of the TRE findings. Copies of the TRE Activities Report shall also be submitted to the U.S. EPA Region 6 office. e. During the TRE, the permittee shall perform, at a minimum, quarterly testing using the more sensitive species; testing for the less sensitive species shall continue at the frequency specified in Part s.b. f. If the effluent ceases to effect significant lethality (herein as defined below) the permittee may end the TRE. A "cessation of lethality" is defined as no significant lethality for a period of 12 consecutive months with at least monthly testing. At the end of the 12 months, the permittee shall submit a statement of intent to cease the TRE and may then resume the testing frequency specified in Part i.b. The permittee may only apply the "cessation of lethality" provision once. This provision accommodates situations where operational errors and upsets, spills, or sampling errors triggered the TRE, in contrast to a situation where a single toxicant or group of toxicants cause lethality. This provision does not apply as a result of corrective actions taken by the permittee. "Corrective actions" are herein defined as proactive efforts which eliminate or reduce effluent toxicity. These include, but are not limited to, source reduction or elimination, improved housekeeping, changes in chemical usage, and modifications of influent streams and effluent treatment. The permittee may only apply this cessation of lethality provision once. If the effluent again demonstrates significant lethality to the same species, the permit will be amended to add a WET limit with a compliance period, if appropriate. However, prior to the effective date of the WET limit, the permittee may apply for a permit amendment removing and replacing the WET limit with an alternate toxicity control measure by identifying and confirming the toxicant and an appropriate control measure. g. The permittee shall complete the TRE and submit a Final Report on the TRE Activities no later than 28 months from the last test day of the retest that confirmed significant lethal effects at the critical dilution. The permittee may petition the Executive Director (in writing) for an extension of the 28 -month limit. However, to warrant an extension the permittee must have demonstrated due diligence in their pursuit of the TIE/TRE and must prove that circumstances beyond their control stalled the TIE/TRE. The report shall provide information pertaining to the specific control mechanism(s) selected that will, when implemented, result in reduction of effluent toxicity to no significant lethality at the critical dilution. The report will also provide a specific corrective action schedule for implementing the selected control mechanism(s). A copy of the TRE Final Report shall also be submitted to the U.S. EPA Region 6 office. h. Based upon the results of the TRE and proposed corrective actions, this permit Page 58 City of La Porte Page 59 TPDES Permit No. WQ00102o5oox may be amended to modify the biomonitoring requirements, where necessary, to require a compliance schedule for implementation of corrective actions, to specify a WET limit, to specify a BMP, and to specify CS limits.

However, to warrant an extension the permittee must have demonstrated due diligence in their pursuit of the TIE/TRE and must prove that circumstances beyond their control stalled Page 68 City of La Porte TPDES Permit No. WQ00102o600i the TIE/TRE. The report shall specify the control mechanism(s) that will, when implemented, reduce effluent toxicity as specified in item 5.9. The report will also specify a corrective action schedule for implementing the selected control mechanism(s). A copy of the TRE Final Report shall also be submitted to the U.S. EPA Region 6 office. I Within 3 years of the last day of the test confirming toxicity, the permittee shall comply with 307.6.(e)(2)(B), which requires greater than 50% survival of the test organism in l00% effluent at the end of 24 -hours. The permittee may petition the Executive Director (in writing) for an extension of the 3 -year limit. However, to warrant an extension the permittee must have demonstrated due diligence in their pursuit of the TIE/TRE and must prove that circumstances beyond their control stalled the TIE/TRE. The requirement to comply with 307.6.(e)(2)(B) may be exempted upon proof that toxicity is caused by an excess, imbalance, or deficiency of dissolved salts. This exemption excludes instances where individually toxic components (e.g. metals) form a salt compound. Following the exemption, the permit may be amended to include an ion -adjustment protocol, alternate species testing, or single species testing. L Based upon the results of the TRE and proposed corrective actions, this permit may be amended to modify the biomonitoring requirements where necessary, to require a compliance schedule for implementation of corrective actions, to specify a WET limit, to specify a BMP, and to specify a CS limit.
