923.08 USE OF PUBLIC SEWERS.
   (a)   Prohibition of Unpolluted Water. No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, downspouts, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process water to any sanitary sewer.
   (b)   Allowable Discharge of Unpolluted Water. Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm drain or to a natural outlet approved by the Service Director and other regulatory agencies. Unpolluted industrial cooling water or process waters may be discharged on approval by the Director to a storm sewer, or natural outlet. (Ord. 2004-24. Passed 4-13-04.)
   
   (c)   Septic Tank Wastes.
      (1)   No person shall deposit septic tank wastes into a public sewer, storm sewer, sanitary sewer or drainage system. Septic tank wastes shall be transported to the wastewater treatment plant and disposed of in a manner acceptable to the Wastewater Superintendent or his/her designee.
         A.   The fee for dumping domestic septic tank wastes at the wastewater treatment plant shall be eight cents ($.08) per gallon.
         B.   The fee for dumping wastes other than domestic septic tank wastes at the wastewater treatment plant shall be twenty cents ($.20) per gallon.
      (2)   The Wastewater Superintendent or his/her designee shall have sole discretion as to what substances are acceptable. Examples of substances deemed non-domestic waste shall be all material from commercial or industrial waste pits, tanks or traps that contain other than domestic sanitary wastes such as concentrated food processing wastes, pizza parts, salad wastes, vegetables, etc. Any wastes containing concentrated oils and greases such as petroleum base oils, product or mineral oils origin or floatable oils, fats, wax or grease of any type. Examples of prohibited waste would be defined as any wastes containing non-biodegradable material, cutting oils, flammable or explosive liquids, solid or gas of any nature.
      (3)   All approved septic tank wastes shall be deposited at the Wastewater Treatment Plant at the designated septage receiving station or the ATAD system. A required form must be filled out and approved before discharging the wastes. The form will consist of dates, times, total gallons and the nature and types of wastes. Any commercial business or industrial wastes to be discharged at the designated site must be inspected and approved/disapproved by wastewater treatment plant personnel before discharge.
         (Ord. 2010-4. Passed 2-11-10.)
   (d)   Substances Prohibited. No person shall discharge or cause to be discharged any of the following described water or wastes to any public sewers:
      (1)   Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid or gas.
      (2)   Any waters or wastes having a pH lower than 6.0, higher than 10.5 having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the wastewater works.
      (3)   Solids 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 animal blood, manure, animal hair and fleshings, animal entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
      (4)   Any substance that alone or in combination with other substances may cause this wastewater treatment works to violate any permit or law.
   (e)   Substances Limited. The following described substances, materials, waters, or waste shall be limited in discharges to municipal systems to concentrations or quantities which will not harm or block the sewers, or pass through or interfere with wastewater treatment processes or equipment; or cause or contribute to violation of the wastewater treatment plant NPDES permit; will not have an adverse effect on the receiving stream; or will not otherwise endanger lives, limb, public property, or constitute a nuisance. The Director may set limitations lower than the limitations established in the regulations below if in his opinion such more stringent limitations are necessary to meet the above objectives. Deliberate dilution with unpolluted water to meet the concentrations established in the regulations below shall not be acceptable. In forming his opinion as to the acceptability, the Director will give consideration to such facts as the quantity of subject waste in relation to flows and velocities in the sewers, materials of construction of the sewers, the wastewater treatment process employed, capacity of the wastewater treatment plant, degree of treatability of the waste in the wastewater treatment plant and other pertinent factors. The limitations or restrictions on materials or characteristics of waste or wastewater discharged to the sanitary sewer which shall not be violated without approval of the Director are as follows:
      (1)   Wastewater having a temperature higher than 150oF.
      (2)   Wastewater containing more than fifty milligrams per liter of petroleum oil, nonbiodegradeable cutting oils, product of mineral oil origin or floatable oils, fat, wax or grease.
      (3)   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.
      (4)   Any water or wastes containing solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the wastewater treatment plant, including but not limited to cyanides, hexavalent chromium, copper, zinc, cadmium, nickel and phenols in the wastes as discharged to the public sewer. The following concentrations shall not be exceeded in any wastes discharged to the public sewers:
 
Total cyanide (CN), none permitted
Hexavalent chromium, 0.5 mg/l
Copper, 0.2 mg/l
Zinc, 1.0 mg/l
Cadmium, 0.2 mg/l
Nickel, 0.2 mg/l
Phenols, 0.2 mg/l
Lead, 0.5 mg/l
Mercury, 0.01 mg/l
Silver, 0.2 mg/l
   These maximum concentrations may be changed as necessary by the Director or State regulatory agencies based on new information concerning inhibitory substances or to protect treatment plant processes or personnel. Industrial discharges shall be further regulated by Chapter 924.
      (5)   Any waters or wastes containing odor-producing substances exceeding limits which may be established by the Director or any local or State regulatory agencies.
      (6)   Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits in compliance with applicable State or Federal regulations.
      (7)   Quantities of flow, concentration or both which constitute a “slug” as defined herein.
      (8)   Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment process employed, or are amenable only to such degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
      (9)   Any water or wastes which by interaction with other water or wastes in the public sewer system, release obnoxious gases, form suspended solids which interfere with the collection system, or create a condition deleterious to structures and treatment processes.
   (f)   Authority for Control of Wastewater Discharges.
      (1)   If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which contain the substances or possess the characteristics enumerated in subsection (e)(3) or (4) hereof, and which in the judgment of the Director, may have a deleterious effect upon the wastewater facilities, processes, equipment, or receiving waters, including violation of applicable water quality standards, or which otherwise create a hazard to life or constitute a public nuisance, the Director may:
         A.   Reject the waste;
         B.   Require pretreatment o an acceptable condition for discharge to the public sewers;
         C.   Require control over the quantities and rates of discharge; and/or,
         D.   Require payment to cover the added cost of handling and treatment of the wastes.
      (2)   If the Director requires 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 Director and State regulatory agencies and subject to the requirements of all applicable codes, ordinances and laws.
   (g)   Grease and Oil Interceptors. For grease, oil, petroleum products, inorganic material and other materials as listed in the Ohio Basic Building Code such as sand, grit, etc., interceptors shall be provided when in the opinion of the Director they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts, as specified in subsection (e)(2) 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 Director and shall be located as to be readily and easily accessible for cleaning and inspection. In the maintaining of these interceptors the owner(s) 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 Director. Any removal and hauling of the collected materials not performed by the owner(s)’ personnel must be performed by currently licensed waste disposal firms.
   (h)   Operation of Pretreatment Facilities. 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(s) at his expense.
   (i)   Analyses. All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the latest edition of “Standard Methods for the Examination of Water and Wastewater”, published by the American Public Health Association. Sampling methods, location, times, durations and frequencies are to be determined on an individual basis subject to approval by the Director.
