925.06 GENERAL DISCHARGE PROHIBITIONS.

   (a)   No person shall discharge or cause to be discharged any unpolluted storm water, surface water, ground water, roof run-off, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary sewer. Any existing unpolluted water as described above connected to sanitary or combined sewers shall be connected into an available storm sewer or shall be disconnected above ground in a manner approved by the City Engineer. The owner of all buildings situated within the wastewater system is required at his expense to disconnect all existing roof drains from sanitary and combined sewers in accordance with the provisions of this chapter within ninety days after the date of official notice to do so.

   (b)   Storm water and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the City Engineer or OEPA. Unpolluted industrial cooling water or process waters may be discharged on approval by the City Engineer to a storm sewer, or natural outlet.

   (c)   No person shall discharge or cause to be discharged, directly or indirectly, any of the following described waters or wastes to any public sewers:

      (1)   Pollutants which create a fire or explosion hazard in the POTW, including, but not limited to, wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or sixty degrees Centigrade using the test method specified in 40 CFR 261.21, or any other liquids, solids or gases which by reason of their nature or quantity are, or may be, sufficient either alone or by interaction to cause fire or explosion or be injurious in any other way to the operation of the POTW.

         (Ord. 1992-12. Passed 12-4-01.)

      (2)   Any waters or wastes having a pH lower than 6.0 or greater than 11.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the wastewater works.

         (Ord. 2009-012. Passed 2-17-09.)

      (3)   Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers or other interferences with the proper operation of the wastewater facilities such as, but not limited to, ashes, bones, cinders, sand, mud, straw shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.

      (4)   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 system which exceeds 150 degrees Fahrenheit, or which exceeds 104 degrees Fahrenheit at the entrance to the POTW treatment plant.

      (5)   Wastewater containing petroleum oil, nonbiodegradable cutting oils, products of mineral oil origin or floatable oils, fat, wax or grease, in concentrations exceeding fifty milligrams per liter or in amounts which can pass through or cause interference.

      (6)   Any garbage that has not been properly shredded. Garbage grinders may be connected to sanitary sewers from homes, hotels, institutions, restaurants, hospitals, catering establishments or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers.

      (7)   Any noxious or malodorous liquids, gases or solids which either singly or by interaction are capable of creating a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for their maintenance and repair.

      (8)   Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as exceed limits established in compliance with applicable state or federal regulations.

      (9)   Any slugload, which shall mean any pollutant, including oxygen demanding pollutants (BOD, etc.), released in a single extraordinary discharge episode of such volume or strength as to cause interference to the POTW.

      (10)   Any substance which may cause the POTW's effluent or treatment residues, or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation process.

      (11)   Any substance which will cause the POTW to violate its NPDES and/or other disposal system permits.

      (12)   Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, or to exceed the limitation set forth in national categorical pretreatment standards.

      (13)   Any substance with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions.

      (14)   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.

      (15)   Any wastewater which causes a hazard to human life or creates a public nuisance.
(Ord. 1992-12. Passed 12-4-01.)

   (d)   The following concentrations shall not be exceeded in wastes discharged to the public sewers unless accepted by agreement provided in subsection (h) hereof:

 

COD -       800 mg/1 SS -          300 mg/1 Total Phosphorus -    25 mg/1 Ammonia -       100 mg/l CBOD -       400 mg/l

 

(Ord. 2009-12. Passed 2-17-09.)

   (e)   For grease, oil and inorganic material such as sand, grit, etc., interceptors shall be provided when in the opinion of the Engineer, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts, as specified in subsection (c) (5) hereof, or any flammable wastes, sand or other harmful ingredients: except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Engineer, and shall be located as to be readily and easily accessible for cleaning and inspection. In the maintaining of these interceptors the owner shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates, and means of disposal which are subject to review by the Superintendent.

   (f)   Where pretreatment or flow-equalizing facilities are provided or required for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.
(Ord. 1992-12. Passed 12-4-01.)

   (g)   No person shall discharge trucked or hauled pollutants, including industrial wastes, into any location of the sewer system or POTW at any time. Septic tank, holding tank, and leachate wastes from properly licensed and permitted haulers are accepted at applicable fees. Licensing, permitting, and fees are as outlined in the Wastewater Rules and Regulations.

(Ord. 2001-137. Passed 12-4-01.)

   (h)   No statement contained in this section shall be construed as preventing any special agreement or arrangement between the City and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the City for treatment, subject to possible payment therefor by the industrial concern for subsequent treatment. Any industrial concern may appeal to Council any determination made by the Service Director in the enforcement of this chapter.
