Streets, sidewalks, parkways, and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the Tribe.


  1. Prohibited Discharges: No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which will cause interference or pass through. These general prohibitions apply to all users of the municipal treatment system whether or not the user is subject to categorical pretreatment standards or any other national, tribal or local pretreatment standards or requirements. Wastes prohibited by this section shall not be processed or stored in such a manner that these wastes could be discharged to the treatment system. Furthermore, no user may contribute the following substances to the system: (a) 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 be injurious in any other way to the treatment system. Included in this prohibition are waste streams with a closed cup flashpoint of less than 140E F (60E C) using the test methods prescribed in 40 CFR 261.21. (b) Solid or viscous substances in amounts which will cause interference with the flow in a sewer, and in no case solids greater than one half inch (½”)(1.27 centimeters) in any dimension or garbage that is not properly shredded garbage. (c) Any fat, oils or greases, including but not limited to petroleum oil, non- biodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through. (d) Any wastewater having a pH less than 5.5 or more than 10.0, or which may otherwise cause corrosive structural damage or harm to the system, tribal personnel or equipment. (e) Any wastewater containing pollutants in sufficient quantity (flow or concentration), either singly or by interaction with other pollutants, to pass through or interfere with the treatment system, any wastewater treatment or sludge process, or constitute a hazard to humans or animals. (f) 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. This includes dissolved hydrogen sulfide concentrations exceeding 0.1 mg/l. (g) Any substance, which may cause the treatment plant effluent or any other 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 system cause the Tribe to be in noncompliance with sludge use or disposal regulations or permits issued under applicable tribal or federal law. (h) Any wastewater, which imparts color, which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the treatment plants effluent thereby violating the Tribes NPDES permit. Color (in combination with turbidity) shall not cause the treatment plant effluent to reduce the depth of the compensation point for photosynthetic activity by more than 10 percent from the seasonably established norm for aquatic life. (i) Any wastewater having a temperature greater than 150E F (55E C), or which will inhibit biological activity in the treatment plant resulting in interference, but in no case wastewater which causes the temperature at the introduction into the treatment plant to exceed 104E F (40E C). (j) Any wastewater containing any radioactive waste or isotopes except as specifically approved by the Chief Operator in compliance with applicable federal regulations. (k) Any pollutants, which result in the presence of toxic gases, vapor or fumes within the system in a quantity that may cause worker health and safety problems. (l) Any trucked or hauled pollutant, except at discharge points designated by the Warm Springs Tribe in accordance with Section 431.320 of this Ordinance. (m) Storm water, surface water, groundwater, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, cooling water and unpolluted industrial wastewater, unless specifically authorized by the Chief Operator. (n) Any sludge, screenings, or other residues from the pretreatment of industrial wastes. (o) Any medical wastes, except as specifically authorized by the Chief Operator in a wastewater permit. (p) Any material containing ammonia, ammonia salts, or other chelating agents which will produce metallic complexes that interfere with the treatment system. (q) Any wastewater causing the treatment plant effluent to demonstrate toxicity to test species during a bio-monitoring evaluation. (r) Recognizable portions of the human or animal anatomy. (s) Any wastes containing detergents, surface-active agents, or other substances which may cause excessive foaming in the treatment system.
  2. Specific Pollutant Limitations (a) No nonresidential user shall discharge wastewater containing restricted substances or a slug into the treatment system in excess of limitations specified in its wastewater permit or published by the Chief Operator. The Chief Operator may publish and revise from time to time standards for specific restricted substances. (b) At his or her discretion, the Chief Operator may impose mass limitations in addition to or in place of the concentration-based limitations referenced above.
  3. If any wastewater is discharged or proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated above and which in the judgment of the Chief Operator may have a deleterious effect upon the treatment works, processes, equipment, or receiving waters, or which may otherwise create a hazard to life or constitute a public nuisance, the Chief Operator may: (a) Reject the wastes, sewers, (b) Require pretreatment to an acceptable condition for discharge to the public (c) Require control over the quantities and rates of discharge, and/or (d) If the Chief Operator permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Chief Operator, and subject to the requirements of all applicable codes, ordinances, and laws.
  4. Grease, oil, and sand interceptors shall be provided when, in the opinion of the Chief Operator, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand, or other harmful ingredients. However, such interceptors shall not be required for private residences. All interceptors shall be of a type and capacity approved by the Chief Operator and shall be located so as to be readily and easily accessible for cleaning and inspection.
  5. All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this ordinance shall be determined in accordance with 40 CFR Part 136 or, if 40 CFR Part 136 does not contain sampling or analytical techniques for the pollutant in question, in accordance with procedures approved by the Environmental Protection Agency (EPA). Except as indicated below, wastewater samples collected for purposes of determining compliance with standards and requirements of this ordinance must be obtained using flow proportional composite collection techniques. In the event that flow proportional sampling is infeasible, the Chief Operator may authorize the use of time proportional or grab sampling. Samples for fats, oil and grease (FOG), temperature, pH, cyanide, phenols, sulfides, and volatile organic chemicals must be obtained using grab collection techniques.
  6. No statement contained in this Article shall be construed to prohibit an agreement between the Warm Springs Tribe and any person whereby the Tribe for treatment may accept a discharge of unusual strength or character. Such an agreement may be made when, in the opinion of the Chief Operator, special circumstances justify such agreement, provided that no interference or pass through result from the discharge and no additional costs are incurred by the Tribe without recompense by the person. Federal and Tribal pretreatment standards and requirements shall not be waived by any special agreement of the parties.


  1. All property owners identified by the Tribe as contributors to excessive or improper infiltration or inflow into the treatment works shall be advised of their infiltration and inflow problems.
  2. All such situation properties shall be provided a grace period as determined by the Chief Operator in which to correct the infiltration and inflow problems as identified, said grace period to extend from the date of notification.
  3. By the end of the grace period, each property owner shall notify the Tribe that corrective actions have been taken or are in progress, which actions shall be specified in the notification to the Tribe.
  4. A property owner failing to notify the Tribe of corrective actions prior to the end of the grace period shall be subject to termination of service, without further notice, and water service, if provided by the Tribe, shall be immediately discontinued and shut off until the violation shall have been corrected in accordance with Federal and/or tribal regulations.
  5. In the event any instance of excessive or improper infiltration or inflow into the treatment works of the Tribe shall continue beyond the grace period, it is hereby declared that such continuing infiltration or inflow is a public nuisance, that the Tribe shall have the right to abate such public nuisance, and to enter upon any property within the reservation for such purpose and shall assess the cost of such abatement.


  1. No unauthorized person shall maliciously, willfully, or negligently break, damage, destroy, uncover, deface, or tamper with any structure, appurtenance, or equipment which is a part of the sewage works.
  2. Any person violating this provision shall be subject to immediate arrest under charge of disorderly conduct.


  1. The Chief Operator shall have the right to enter the facilities of any industrial user to ascertain whether the purpose of this Ordinance is being met and all requirements are being complied with.
