Legal Documents of Maryville

1. Any liquids, solids or gases which by reason of their nature or quantity are, or may be, sufficient either alone or by interaction with other substances to cause fire or explosion or by injurious in any other way to the POTW or to the operation of the POTW. No pollutant shall be discharged which create a fire or explosion hazard in the POTW, including, but not limited to, waste streams with a closed cup flash point of less than one hundred forty degrees Fahrenheit (140°F) or sixty degrees Celsius (60°C) using the test methods specified in 40 CFR 261.21. At no time shall two (2) successive readings on an explosion hazard meter at the point of discharge into the system (or at any point in the system) be more than five percent (5%), nor any single reading over ten percent (10%) of the Lower Explosive Limit (LEL) of the meter.
2. Solid or viscous substances which may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater treatment facilities such as, but not limited to, grease, garbage or improperly shredded garbage with particles greater than one-half inch (1/2") in any dimension.
3. Any wastewater having a pH less than 5.0 or greater than 9.5, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment, and/or personnel of the POTW.
4. Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the POTW, or to exceed the limitation set forth in a categorical pretreatment standard. A toxic pollutant shall include, but not be limited to, any pollutant identified pursuant to section 307(a) of the Act.
5. Any noxious or malodorous liquids, gases, or solids which either singly or by interaction with other wastes are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for maintenance and repair.
6. Any substance which may cause the POTW's effluent or any other product of the POTW such as residues, biosolids, sludges, or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case shall a substance discharged to the POTW cause the POTW to be in non-compliance with the sludge use or disposal criteria, guidelines or regulations developed under section 405 of the Act; any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act, the Clean Water Act, or federal or state criteria applicable to the sludge management method being used.
7. Any substance which will cause the POTW to violate its NPDES and/or state disposal system permit, the receiving water quality standards, or cause a passthrough violation.
8. Any wastewater with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions.
9. Any wastewater having a temperature which will inhibit biological activity in the POTW treatment plant resulting in interference, but in no case wastewater with a temperature at the introduction into the POTW which exceeds sixty-five degrees Celsius (65°C) one hundred fifty degrees Fahrenheit (150°F) or cause the influent of the wastewater treatment plant to exceed forty degrees Celsius (40°C) one hundred four degrees Fahrenheit (104°F) unless the POTW treatment plant is designed to accommodate such temperature.
10. Any pollutants, including oxygen demanding pollutants (BOD, etc.) released at a flow rate and/or pollutant concentration which will cause interference to the POTW. In no case shall a slug discharge have a flow rate or contain concentration or quantities of pollutants that exceed for any time period longer than fifteen (15) minutes more than five (5) times the average twenty-four (24) hour concentration, quantities, or flow during normal operation.
11. Any wastewater containing any radioactive wastes or isotopes of such half life or concentration as may exceed limits established by the control authority in compliance with applicable state or federal regulations.
12. Any wastewater which causes a hazard to human life or creates a public nuisance.
13. Any stormwater (flow occurring during or following any form of natural precipitation and resulting therefrom), surface water, groundwater, roof runoff, subsurface drainage, to any sanitary sewer. Storm water drainage shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the state. Uncontaminated industrial cooling water or unpolluted process waters may be discharged on approval of the state to a storm sewer or natural outlet. Landfill leachate and discharge from temporary groundwater remediation projects may be discharged to the sewer system in accordance with this chapter upon approval by the control authority.
14. Any wastewater containing fats, wax, grease, petroleum oil, nonbiodegradeable cutting oil or products of mineral oil origin, or other substances which may solidify or become viscous at temperatures between zero degrees Celsius (0°C) thirty-two degrees Fahrenheit (32°F) and forty degrees Celsius (40°C) one hundred four degrees Fahrenheit (l04°F) and/or cause interference or pass-through at the POTW treatment plant.
15. Pollutants which result in the presence of toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems.

16. Any trucked or hauled pollutants, except at discharge points designated by the POTW and in accordance with the requirements of this ordinance.

    When the control authority determines that a user(s) is contributing to the POTW any of the above enumerated substances in such amounts as to interfere with the operation of the POTW, the control authority shall

    1. Advise the user(s) of the impact of the contribution on the POTW and
    2. Develop effluent limitations for such user(s) to correct the interference with the POTW.

Limitations on wastewater strength. No person or user shall discharge wastewater to the POTW in excess of the concentration set forth in Table 18-202(4) (next page) unless:

1. An exception has been granted the user by the control authority; or
2. The wastewater discharge permit of the user provides as a special permit condition a higher interim concentration level in conjunction with a requirement that the user construct a pretreatment facility or institute changes in operation and maintenance procedures to reduce the concentration of pollutants to levels not exceeding the standards set forth in Table 18-202(4) within a fixed period of time.
    

TABLE 18-202(4)

Limits on Wastewater Discharged by Users
 

Any user discharging wastewater having pollutants in excess of the concentrations listed above may be subject to fines and/or other enforcement actions as outlined in § 18-208 hereinafter.

Criteria to protect the treatment plant influent. No person or user shall discharge any waters or wastes which cause the wastewater arriving at the treatment facility to exceed any of the concentration limits shown in Table 18-202(5) hereinafter. Users may be subject to reporting and monitoring requirements for all or a part of these parameters.

The control authority shall monitor the treatment works influent for the parameters in Table 18-202(5). In the event that the influent at the treatment works reaches or exceeds the levels established by said table, the Control Authority shall initiate technical studies to determine the cause of the influent violation, and shall recommend to the city council such remedial measures as are necessary, included, but not limited to, recommending the establishment of new or revised pretreatment levels for these parameters. The control authority shall also recommend changes to any of these criteria in the event the POTW effluent standards are changed or in the event that there are changes in any applicable law or regulation affecting same or in the event changes are needed for more effective operation of the POTW.

TABLE 18-202(5)

Protection Limits at Treatment Works Influent

1. Protection from slug discharges. Each user shall provide protection from slug discharge of prohibited materials or other substances regulated by this ordinance. Facilities to prevent slug discharge of prohibited material shall be provided and maintained at the owner or user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the control authority for review, and shall be approved by the control authority before construction of the facility. All existing users shall complete such a plan within one hundred eighty (180) days from the effective date of this ordinance. No user who commences contribution to the POTW after the effective date of this ordinance shall be permitted to introduce pollutants into the system until a slug discharge control plan has been approved by the control authority. Significant industrial users are required to notify the control authority immediately of any changes at its facility affecting potential for a slug discharge.

   Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify the user's facility as necessary to meet the requirements of this ordinance. In the case of a slug discharge, it is the responsibility of the User to immediately telephone and notify the POTW of the incident. The notification shall include location of discharge, type of waste, concentration and volume, and corrective actions.

2. Written notice of slug discharges. Within five (5) days following a slug discharge the user shall submit to the control authority a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW, fish kills, or any other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties, or other liability which may be imposed by this article or other applicable law.
3. Notice to employees. A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees whom to call in the event of a slug discharge. Employers shall insure that all employees who may cause or suffer such a slug discharge to occur are advised of the emergency notification procedure. In lieu of placing notices on bulletin boards, the user may submit an approved slug control plan.

Discharge of hazardous wastes. All industrial users shall notify the control authority, the EPA Region IV Resource Conservation and Restoration Division, and the Tennessee Department of Environment and Conservation Division of Solid Waste Management 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. The notification must 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).

If the industrial user discharges more than one hundred (100) kilograms of such wastes 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: An identification of the hazardous constituents contained in the wastes, an estimate of the mass and concentration of such constituents discharged during that calendar month, and an estimate of the mass and concentration of such constituents expected to be discharged during the following twelve (12) months.

Notification shall be provided within one hundred eighty (180) days of the discharge. Notification need be submitted only once for each hazardous waste discharged; however, advance notification of substantial change is required.

Industrial users are exempt from notification requirements 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 Tennessee Rule 0400-1-11-.02(4)(a) and (4)(d).

If new regulations identify additional characteristics of hazardous wastes or list new hazardous wastes, notification of the appropriate authorities by the industrial user is required within ninety (90) days of the effective date of such regulations.

If notification is required, the industrial 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.
