(Ordinance No. G -94-05-26-9B of May 26, 1994) 10.412 Affirmative Defenses to Discharge Violations (1) Act of God defense. (a) Act of God defense/ The Act of God defense constitutes a statutory affirmative defense [Texas Water Code Section 7.251] in an action brought in municipal of Sate 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. Act of God does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or careless or improper operation. (b) An industrial user who wishes to establish the Act of God affirmative defense shall demonstrate, through relevant evidence that: (1) An event that would otherwise be a violation of the 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 24 (2) The industrial user 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 ordinance (if this information is provided orally, a written submission must be provided within five (5) days): a. A description of the event, and the nature and cause of the event; b. The time period of the event, including 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 the Act of God affirmative defense shall have the 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 ordinance, was caused solely by an act of God, war, strike, riot or other catastrophe. (d) Users shall control production of all discharges to the extent necessary to maintain compliance with pretreatment requirements upon reduction, loss, or failure of its treatment facility until the facility is restored or an alternative method of treatment is provided. This requirement applies in the situation where, among other things, the primary source of power for the treatment facility is reduced, lost, or fails. (2) Bypass (a) Bypass means the intentional diversion of wastestreams from any portion of a user's treatment facility. (b) 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. (c) A user may allow any bypass to occur which does not cause pretreatment standards or requirements to be violated, but only if it also is for essential maintenance to assure efficient operation. (d) If a user knows in advance of the need for a bypass, it shall submit prior notice to the Control Authority at least ten days before the date of the bypass, if possible. (e) A user shall submit oral notice to the Control Authority of an unanticipated bypass that exceeds applicable pretreatment requirements within twenty-four (24) hours from the time it becomes aware of the bypass. A written submission shall also be provided within five (5) days from the time the user becomes aware of the bypass. The written submission shall contain a description of the bypass and 25 its cause; the duration of the bypass, including exact dates and times, and, if the bypass has not been corrected, the anticipated time it is expected to continue; and steps taken or planned to reduce eliminate, and prevent reoccurrence of the bypass. The Control Authority may waive the written report on a case-by-case basis if proper oral notice has been given. (0 Bypass is prohibited, and the Control Authority may take an enforcement action against a user for a bypass, unless (g) (i) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage; (ii) There were no feasible alternatives to the bypass, such as the use auxiliary treatment facilities, retention of untreated wastes, or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate back-up equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (iii)The user submitted notices as stated herein. The Control Authority may approve an anticipated bypass, after considering its adverse effects, if the Control Authority determines that it will meet the three conditions in paragraph (f) above.

That Chapter 10, Sections 10.600, Environmental Services Fees, Code of Ordinances (1995 Edition), City of Round Rock is hereby amended as follows: Section 10.600 ENVIRONMENTAL SERVICES FEES In order to ensure an equitable cost recovery system, the Control Authority shall periodically review the fees and adjust them as appropriate. 10.601 WASTEWATER DISCHARGE PERMIT APPLICATIONS AND SURCHARGE (1) Applicability This section shall be applicable to all nondomestic dischargers to the Brushy Creek Regional Wastewater System. (2) Definitions All words and phrases used in this Section shall have the same meaning as the words and phrases defined in Section 10.402. (3) Wastewater Discharge Permit Application A user is subject to the following application fees: 27 Significant Other Users Users New Permit $100 $25 Permit Renewal $100 $25 Permit Modification $100 $25 Removal credit - A fixed fee for a removal credit application cannot be given because of the circumstances of each user and constituent the credit is applied for are highly variable. Any user or group of users wishing to apply for a removal credit shall assume responsibility for all costs incurred by the City. (4) Surcharge for Higher Concentrations Users shall be assessed a sewer surcharge for nondomestic sewage that contains concentrations of TSS and BOD/COD higher than those defined for domestic sewage herein. The surcharge shall be in addition to any other sewer charges required by other City ordinances. If a user has more than one nondomestic outfall identified in a permit, the surcharge shall be applicable to the daily average total of all nondomestic discharges and not the individual nondomestic discharges.

Computations of surcharges shall be based on the formulas below. The surcharges for individual TSS and BOD/COD are additive. (i) BOD surcharge SBOD = V x 8.34 (A[BOD - 250]) TSS surcharge STSS = V x 8.34 (B[TSS - 2501) COD surcharge 28 where: SCOD = V x 8.34 (C[COD - 450]) S - Sum of surcharges in dollars that will appear on the user's monthly bill. V - Monthly average volume of nondomestic discharge in millions of gallons whichever is the least of the following volumes: (1) total monthly water consumption during the billing period, (2) the average water consumption for the billing periods of December, January, and February of each fiscal year, or; (3) the total estimated or measured nondomestic discharge as determined by methods specified in the user's permit. 8.34 - Conversion factor for units of measure in surcharge equations. A - cost per pound of BOD B - cost per pound of TSS C - cost per pound of COD Fees may be found at Chapter 10 Section 10.202 of the City of Round Rock Code of Ordinances 1990 edition. BOD- BOD concentration in mg/L. For more than one nondomestic discharge, this shall be the flow -weighted concentration. TSS- total suspended solids concentration mg/L. For more than on nondomestic discharge, this shall be the flow -weighted concentration. COD- COD concentration in mg/L. For more than one nondomestic discharge, this shall be the flow -weighted concentration. 250- normal daily average BOD and TSS concentration in mg/L. 450- normal daily average COD in mg/L. (c) Application of Surcharge Surcharge will apply directly to the water meter customer assigned to the discharging user(s). (d) Sampling and Analysis The City shall sample for BOD, TSS, and COD. The time of sampling shall be at the sole discretion of the Control Authority. The Control Authority may select an independent contractor to conduct the sampling and/or analyses. (e) Sampling/Control Point The user shall provide and the Control Authority shall designate a sampling/control point for the purpose of sampling. The location and design of the control point shall be approved by the Control Authority. This sampling point shall be free of impediments and easily accessible by city personnel. (f) Period of Surcharge If analyses for TSS and/or BOD/COD shows that a surcharge is applicable, the surcharge shall be applied to the monthly water bill for a period of six (6) months. (g) Costs of Analyses When analyses show that a surcharge shall be applied, a fee of fifty dollars ($50) shall be added to a user's bill to cover the sampling, handling, and laboratory analyses. When analyses show that a surcharge shall not be applied, then this fee shall not be added to the user's bill. (h) Contested Charges User must contest any/all charges within fourteen (14) days of issuance of surcharge notification. 10.602 This Section reserved for future use. 10.603 ANALYTICAL AND SAMPLING FEES (1) Applicability The fees described herein do not apply to any sampling event or analytical work initiated by the City for the purposes of its own routine testing and monitoring.

MARTINEZ, City Secreta 32 DATE: August 22, 2003 SUBJECT: City Council Meeting - August 28, 2003 ITEM: *9.B.1. Consider an ordinance amending Chapter 10, Section 10.400 and 10.600 of the Code of Ordinance (1995 Edition) to incorporate Texas Commission on Environmental Quality (TCEQ) changes into the existing pretreatment program. (Second Reading) Resource: History: Tom Word, Chief of Public Works Operations Tom Clark, Utility Director Tracy Herring, Environmental Services Supervisor Through the wastewater contract with the Lower Colorado River Authority (LCRA) and Brazos River Authority (BRA), the city is required to operate and maintain a Texas Commission on Environmental Quality (TCEQ) approved pretreatment program. The TCEQ has requested that the program currently in place be substantially modified. These changes are necessary to reflect new rules and regulations and to streamline the program. The most notable change is in Section 10.403(3) local limits that are applicable to all wastewater dischargers. These limits are periodically reviewed and are derived to protect the wastewater treatment plant and in turn the receiving waters of Brushy Creek. These numbers were derived by both the Brazos River Authority (BRA) and TCEQ. TCEQ gave final approval to these limits and to the entire revised 10.400 ordinance. Funding: Cost: N/A Source of funds: N/A Outside Resources: N/A Impact/Benefit: Amending Section 10.400, will bring the pretreatment program in compliance with required industry standards.
