Legal Documents of Jefferson City

1. General prohibitions. No user shall contribute or cause to be contributed into the POTW, directly or indirectly, any pollutant or wastewater which causes interference or pass through. These general prohibitions apply to all users of a POTW whether or not the user is a Significant Industrial User (SIU) or subject to any national, state, or local pretreatment standards or requirements.

2. Specific prohibitions. No user shall contribute or cause to be contributed into the POTW the following pollutants, substances, or wastewater:

   1. Pollutants which create a fire or explosive hazard in the POTW, including, but not limited to, waste streams with a closed cup flashpoint of less than one hundred forty degrees Fahrenheit (140° F) sixty degrees Centigrade (60°C) using the test methods specified in 40 CFR 261.21.
   2. Solid or viscous substances in amounts which will cause obstruction of the flow in the POTW resulting in interference, but in no case solids greater than one half inch (1/ 2") in any dimension.
   3. Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through.
   4. Any wastewater having a pH less than 5.0 or wastewater having any other corrosive property capable of causing damage to the POTW or equipment.
   5. Any wastewater containing pollutants, including oxygen-demanding pollutants, (BOD, etc.) in sufficient quantity, (flow or concentration) either singly or by interaction with other pollutants, to cause interference with the POTW.
   6. Any wastewater having a temperature greater than one hundred fifty degrees Fahrenheit (150° F) sixty six degrees Centigrade (66° C), or which will inhibit biological activity in the POTW treatment plant resulting in interference, but in no case wastewater which causes the temperature at the introduction into the treatment plant to exceed one hundred degrees Fahrenheit (104° F) forty degrees Centigrade (40° C).
   7. Any 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.
   8. Any trucked or hauled pollutants. Unless specifically authorized by the public works director at a discharge point specifically designated by the POTW.
   9. Any noxious or malodorous liquids, gases, or solids or other wastewater 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.
   10. Any substance which may cause the POTW's effluent or any other product of the POTW such as residues, 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 sludge use or disposal regulations or permits issued under section 405 of the Act; the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act, or state criteria applicable to the sludge management method being used.
   11. Any wastewater which imparts color which is not removed by the treatment process, including, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts sufficient color to the treatment plant's effluent to render the waters injurious to public health or secondary recreation or to aquatic life and wildlife or to adversely affect the palatability of fish or aesthetic quality or impair the receiving waters for any designated uses.
   12. Any wastewater containing an y radioactive wastes or isotopes except as specifically approved by the public works director in compliance with applicable state or federal regulations.
   13. Storm water, surface water, ground water, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, non- contact cooling water and unpolluted industrial wastewater, unless specifically authorized by the public works director.
   14. Fats, oils, or greases of animal or vegetable origin in concentrations greater than three hundred (300) mg/l, unless otherwise authorized in writing.
   15. Any sludges, screenings or other residues from the pretreatment of industrial wastes.
   16. Any medical wastes, except as specifically authorized by the public works director in a wastewater discharge permit.
   17. Any material containing ammonia, ammonia salts, or other chelating agents which will produce metallic complexes that interfere with the municipal wastewater system.
   18. Any material that would be identified as hazardous waste according to 40 CFR part 261 if not disposed of in a sewer except as may be specifically authorized by the public works director.
   19. Any wastewater causing the treatment plant effluent to violate state water quality standards for toxic substances as described in 15A NCAC 2B .0200.
   20. Wastewater causing, alone or in conjunction with other sources, the treatment plant's effluent to fail a toxicity test.
   21. Recognizable portions of the human or animal anatomy.
   22. Any waste containing detergents, surface active agents, or other substances which may cause excessive foaming in the municipal wastewater system.
   23. Any wastes causing two successive readings on an explosion hazard meter at the point of discharge into the system (or at any point in the system) of more than five percent (5%) or which causes any single reading ten percent (10%) of higher than the Lower Explosive Limit (LEL) of the meter.

   Pollutants, substances, wastewater, or other wastes prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the municipal wastewater system. All floor drains located in process or materials storage areas must discharge to the industrial user's pretreatment facility before connecting with the system. For existing buildings proposing new connections, all floor drains must be verified by dye testing, or other verifiable method, of each individual drain.

   When the public works director determines that a user is contributing to the POTW any of the above enumerated substances in such amounts which may cause or contribute to interference of POTW operation or pass through, the public works director shall:

   1. Advise the user of the potential impact of the contribution on the POTW in accordance with § 18-608(1); and
   2. Take appropriate actions in accordance with § 18-604 for such user to protect the POTW from interference or pass through.

1. Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the public works director may impose equivalent concentration or mass limits in accordance with 40 CFR 403.6(c).
2. When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the public works director shall impose an alternate limit using the combined waste stream formula in 40 CFR 403.6(e).
3. A user may obtain a variance from a categorical pretreatment standard if the user can prove, pursuant to the procedural and substantive provisions in 40 CFR 403.13, that factors relating to its discharge are fundamentally different from the factors considered by EPA when developing the categorical pretreatment standard.
4. A user may obtain a net gross adjustment to a categorical standard in accordance with 40 CFR.403.15.

Local limits. To implement the general and average discharge prohibitions listed in this policy, industrial user specific discharge limits will be developed ensuring that the POTW's maximum allowable headworks loading is not exceeded for particular pollutants of concern for each industrial user. These local limits will apply to all users and can be found at City of Jefferson City's Public Works Facility. Local limits will be established for the following pollutants:

BOD
TSS
NH3
Arsenic
Benzene
Cadmium (a,b)
Carbon Tetrachloride
Chloroform
Chromium, I ll
Chromium, VI
Copper (a,b)
Cyanide (d)
Ethylbenzene
Lead (a,b)
Mercury {c)
Methylene Chloride
Naphthalene
Nickel {a,b)
Phenols, Total
Phthalates, Total¹
Silver (a,b,c)
Tetrachloroethylene
Trichloroethylene
Total Chromium
Toluene
1, 2 Trans Dichloroethylene
1,1,1 Trichloroethane
Zinc (a,b)

¹Total Phthalates is the sum of Bis (2-ethylhexyl phthalate, Butyl benzylphthalate, Di-n-butyl phthalate and Diethyl phthalate.

Note: These local limits may be expressed in daily maximum and/or monthly averages. All sampling and analysis must be in accordance with 40 CFR 136 unless explicitly allowed by the NPDES permit. See part 3.2. of the NPDES permit for sample type requirements. References include T.C.A 0400-40-14-.12(7)(c), 40 CFR 136, and EPA Form 3510-2C (8/90 version).

1. Denotes metals for which fish and aquatic life criteria are expressed as a function of total hardness.
2. The criteria for this metal is in the dissolved form at lab conditions. The calculated effluent concentration is in the total recoverable form.
3. The chronic criteria for mercury is not converted to dissolved, since it is based on fish tissue data rather than toxicity.
4. The criteria for this parameter is in the total form.
5. Silver limit is daily max.

1. Pretreatment facilities. Users shall provide wastewater treatment as necessary to comply with this policy and wastewater permits issued under § 18-604(2) of this policy and shall achieve compliance with all national categorical pretreatment standards, local limits, and the prohibitions set out in § 18-602(1) of this policy within the time limitations as specified by EPA, the state, or the public works director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the city for review and shall be approved by the public works director before construction of the facility. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent acceptable to the city under the provisions of this policy. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be approved by the public works director prior to the user's initiation of the changes.
2. Additional pretreatment measures.
   1. Whenever deemed necessary, the public works director may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage waste streams from industrial waste streams, and take such other actions as may be necessary to protect the POTW and enable the public works director to determine whether the user is complying with the requirements of this policy.
   2. The public works director may require any person discharging into the POTW to install and maintain, on his property and at his expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.
   3. Grease, oil, and sand interceptors shall be provided when, in the opinion of the public works 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 interception units shall be of type and capacity approved by the public works director and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the user at his expense.
   4. Users with the potential to discharge flammable substances may be required to install and maintain an approved combustible gas detection meter.

1. At least once every two (2) years, the public works director shall evaluate whether each SIU needs a plan to control and prevent slug discharges and accidental discharges as defined in § 18-601(2)(oo). All SIUs must be evaluated within one (1) year of being designated a SIU. The public works director may require any user to develop, submit for approval and implement such a plan.
2. All SIUs are required to notify the POTW immediately of any changes at its facility affecting the potential nature for spills and other accidental discharge, discharge of a non-routine, episodic nature, a non-customary batch discharge, or a slug load. Also, see § 18-605(5) and (6).
3. Alternatively, the public works director may develop such a plan for any user. An accidental discharge/slug control plan shall address, at a minimum, the following:
   1. Description of discharge practices, including non-routine batch discharges;
   2. Description of stored chemicals;
   3. Procedures for immediately notifying the public works director of any accidental or slug discharge, as required by § 18-605(6) of this policy; and
   4. Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including, solvents, and/ or measures and equipment for emergency response.
