(a) 
State requirements and limitations on discharges to the POTW shall be met by all dischargers which are subject to such standards in any instance in which they are more stringent than federal requirements and limitations or those in this article or any other applicable ordinance.
(b) 
No discharger shall increase the use of potable or process water in any way for the purpose of diluting a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the standards set forth in this article.
(c) 
Where deemed appropriate, the authority may apply mass limitations expressed in pounds per day of pollutant discharged.
(d) 
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).
(Ordinance 450-12, sec. 4(A), adopted 1/19/12)
(a) 
Each discharger shall provide protection from accidental discharge of prohibited or regulated materials or substances established by this article. Where necessary, facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the discharger’s cost and expense. When applicable, detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the authority for review, and shall be approved by the authority before construction of the facility. Review and approval of such plans and operating procedures by the authority shall not relieve the discharger from the responsibility to modify its facility as necessary to meet the requirements of this article.
(b) 
Dischargers shall notify the authority and the control authority immediately upon the occurrence of a “slug” or accidental discharge of substances prohibited by this article. The notification shall include the location of discharge, date and time thereof, type of waste, concentration and volume, and corrective actions taken, and be signed by the discharger’s authorized representative. Within five (5) days following such discharge, the user shall, unless waived by the director, submit to the director a detailed written report which specifies: a description and cause of the discharge, including location of the discharge, type, concentration, and volume of water; duration of noncompliance including exact dates and times of noncompliance and, if the noncompliance is continuing, an immediate response to cause the noncompliant discharge to cease; and all steps taken or to be taken to reduce, eliminate, and prevent continuation or recurrence of such an upset, slug load, or accidental discharge, spill, or other conditions of noncompliance. Any discharger discharging slugs of prohibited materials shall be liable for any expense, loss or damage to the POTW, in addition to the amount of any fines imposed on the authority under state or federal law.
(c) 
A notice shall be permanently posted on the user’s bulletin board or other prominent place advising employees who to call in the event of a discharge described in this article. Each employer shall instruct all applicable employees who may cause or discover such a discharge with respect to the emergency notification procedure, including the proper telephone number of the authority to be notified.
(Ordinance 450-12, sec. 4(B), adopted 1/19/12)
All dischargers who discharge wastewater into a private sewer system shall comply with this article, including section 13.06.091(g); provided, however, that flow measurement may be based on metered water consumption. Each discharger shall provide an agreement, signed by the owner of the sewer system, which authorizes the authority’s personnel to enter onto the owner’s property for purposes of inspection and monitoring of the discharger’s premises, and for enforcement pursuant to the terms of this article.
(Ordinance 450-12, sec. 4(C), adopted 1/19/12)
(a) 
Bypass of a discharger’s treatment equipment or treatment facility is prohibited and the authority may take enforcement action against the discharger unless:
(1) 
The bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;
(2) 
There were no feasible alternatives to the bypass, such as use of auxiliary treatment facilities, retention of untreated wastewater, or maintenance during normal periods of downtime. This condition is not satisfied if, in the exercise of reasonable engineering judgment, adequate backup equipment should have been installed to prevent a bypass which occurred during normal periods of equipment downtime or maintenance; and
(3) 
The discharger submitted advance written notice of the need for a bypass.
(b) 
The discharger shall submit oral notice to the authority of an unanticipated bypass that exceeds categorical standards or other discharge limits within 24 hours of the time the discharger becomes aware of the bypass. Written notice shall be provided within 5 days of the time the discharger becomes aware of the bypass. The written notice shall include a description of the bypass and its causes, duration of the bypass, and steps taken to prevent the reoccurrence of the bypass, and must be signed by the authorized representative of the discharger.
(c) 
The authority may approve an anticipated bypass after considering its adverse effects, if it determines that the bypass will meet all of the conditions of subsection (a) above.
(Ordinance 450-12, sec. 4(D), adopted 1/19/12)
(a) 
Pursuant to 40 CFR section 403.12(p), any user who commences the discharge of hazardous waste shall notify the director, the EPA Region VI Waste Management Division Director, and the TCEQ, in writing, of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR part 261.
(1) 
Such notification shall include the name of the hazardous waste as set forth in 40 CFR part 261, the EPA hazardous waste number, and the type of discharge (continuous, batch, or other).
(2) 
If the user discharges more than one hundred (100) kilograms of such waste per calendar month to the POTW, the notification also shall contain the following information to the extent such information is known and readily available to the user: an identification of the hazardous constituents contained in the wastes, an estimation of the mass and concentration of such constituents in the waste stream discharged during that calendar month, and an estimation of the mass of constituents in the waste stream expected to be discharged during the following twelve (12) months.
(3) 
All notifications shall take place no later than one hundred eighty (180) days after the discharge commences. Any notification under this subsection need be submitted only once for each hazardous waste discharged. However, notifications of changed conditions shall be submitted as per this article. The notification requirement in this section does not apply to pollutants already reported by users subject to categorical pretreatment standards under the self-monitoring requirements of this article.
(b) 
Dischargers are exempt from the requirements of subsection (a) during a calendar month in which they discharge no more than fifteen (15) kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e). Discharge of more than fifteen (15) kilograms of non-acute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), requires a one-time notification. Subsequent months during which the user discharges more than such quantities of any hazardous waste do not require additional notification.
(c) 
In the case of any new regulations under section 3001 of RCRA identifying additional characteristics of hazardous waste or listing any additional substance as a hazardous waste, the user shall notify the director, the EPA Region VI Waste Management Division Director, and the TCEQ, of the discharge of such substance within ninety (90) days of the effective date of such regulations.
(d) 
In the case of any notification made under this section, the user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical.
(e) 
This provision does not create a right to discharge any substance not otherwise permitted to be discharged by this article, a permit issued thereunder, or any applicable federal or state law.
(Ordinance 450-12, sec. 4(E), adopted 1/19/12)
The director shall evaluate whether each significant industrial user needs an accidental discharge/slug control plan or other action to control slug discharges at the time of SIU determination, or at least by the first year. All the activities associated with slug control evaluation and results are to be kept in the industrial user file. The director may require any user to develop, submit for approval, and implement such a plan or take such other action that may be necessary to control slug discharges. Alternatively, the director may develop such a plan for any user. An accidental discharge/slug plan shall address, at the minimum the following:
(1) 
Description of discharge practices, including nonroutine batch discharges;
(2) 
Description of stored chemicals;
(3) 
Procedures for immediately notifying the director of any accidental or slug discharge, as required by this article; and
(4) 
Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.
(Ordinance 450-12, sec. 4(F), adopted 1/19/12)
