(a)   No 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 treatment works.
   (b)   No person shall discharge or cause to be discharged any unpolluted waters such as stormwater, groundwater, roof runoff, subsurface drainage, or cooling water to any sanitary sewer, except stormwater runoff from limited areas, which stormwater may be polluted at times, may be discharged to the sanitary sewer by permission of the Administrator.
   (c)   (1)   Whenever the Administrator shall find that any provision of (b) above is being violated, he shall issue a written order to the person responsible for the removal, elimination, or correction of such condition(s) to remove such connectors or drains from such sanitary sewer within 90 days after service of such order.
      (2)   The service of such order, as mentioned herein, may be made on the person to whom it is directed, either by delivering a copy of same to such person, or by delivering the same to and leaving it with any person in charge of the premises, or by affixing a copy thereof in a conspicuous place on the door to the entrance of such premises.
   (d)   Stormwater other than that exempted under (b) above and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as combined sewers or storm sewers or to a natural outlet approved by the Administrator and other regulatory agencies. Unpolluted industrial cooling water or process waters may be discharged, on approval of the Municipal Administrator and other regulatory agencies, to a storm sewer, combined sewer, or natural outlet.
   (e)   Whenever sewers are about to be or have been constructed for the purpose of carrying off sewage and drainage from lots and lands outside the corporate limits, no permission shall be given or granted to connect such sewers within the municipal treatment works, nor shall the use of the treatment works be permitted for the sewage and drainage of such lots and lands outside of the corporate limits, unless there shall have been secured written permission from the Municipal Administrator which shall be given only if the sewers or system of sewers for which such connection or use is sought conform to the plans theretofore adopted by the Municipality. A certificate of approval of such sewers by the Ohio Environmental Protection Agency shall also be furnished where, by law, such plans are required to be approved.
   (f)   In addition to the Administrator's approval applicants for permission to use or connect with municipal sewers shall execute such agreements as to terms, conditions, and compensation for the use of such sewers and treatment works as shall be required by the Municipality and authorized by law.
   (g)   No person shall discharge or cause to be discharged any of the following described waters 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 containing toxic or poisonous solids, liquids, or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any waste 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.
      (3)   Any waters or wastes having a pH lower than 6.0, or higher than 10.0 or as otherwise required; or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the wastewater works.
      (4)   Solid or viscous substances in quantities of such size capable of causing obstruction to the flow in sewers, or other interference 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, or entrails.
   (h)   All major contributing industrial users of the treatment facilities shall pretreat any pollutant which may interfere with, pass through, or otherwise be incompatible with the treatment works. Pretreatment of such pollutants shall be in accordance with § 307 of Public Law 92-500 and as determined by the Municipal Administrator. All owners of any source to which pretreatment standards are applicable, shall be in compliance with such standards within the shortest reasonable time, but not later than the date of compliance required by PL 92-500 or the date established by the Administrator, whichever first occurs. All owners of any source to which pretreatment standards are applicable shall submit to the Municipal Administrator semiannual notices regarding specific actions taken to comply with such standards. Such notices shall be submitted on April 1, and October 1. If any major contributing industrial user proposes to pretreat its wastes, the design and installation of the plants and equipment shall be subject to the review and approval of the Municipal Administrator.
   (i)   The following described substances, materials, waters, or waste shall be limited in discharges to the municipal system from all users to concentrations or quantities which will not harm either the sewers, wastewater treatment process, or equipment; will not have an adverse effect on the receiving stream; will not cause violations of the NPDES regulations; or will not otherwise endanger lives, limb, public property, or constitute a nuisance. The Municipal Administrator may set limitations more severe than the limitations established in the regulations below, or in (g) or (h) above, if, in the Administrator's opinion, such more severe limitations are necessary to meet the above objectives. In forming this opinion as to acceptability, the Administrator will give consideration to such factors 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 material or characteristics of waste or wastewaters discharged to the sanitary sewer which shall not be violated without approval of the Administrator are as follows:
      (1)   Wastewater having a temperature higher than 150 °F (65 °C) at the point of entrance to the main sewer.
      (2)   Wastewater containing more than 100 mg/1 of petroleum oil, nonbiodegradable cutting oils, or product of mineral oil origin.
      (3)   Wastewater from industrial plants containing floatable oils, fat, or grease.
      (4)   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.
      (5)   Any waters or wastes containing iron, chromium, copper, zinc, cadmium, and similar objectionable or toxic substances to such degree that any such material received in the composite wastewater at the point of entry to the wastewater treatment works exceeds the limits established by § 307 of Public Law 92-500 and the Administrator, whichever is more stringent. The provisions of (g) and (h) above, this division, and Section 935.12 shall  apply to these requirements.
      (6)   Any waters or wastes containing odor-producing substances exceeding limits which may be established by the Administrator.
      (7)   Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Administrator in compliance with applicable state or federal regulations.
      (8)   Quantities of flow, concentrations, or both, which constitute a slug.
      (9)   Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed, or are amenable to treatment 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.
      (10)   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. The Administrator shall require all discharges to conform to all NPDES permit requirements and any other in specified state or federal regulations.
      (11)   Any water or wastes which produce a color which could interfere with the treatment process, analytical tests, or impart an unnatural color to the treatment plant's effluent.
      (12)   Any substance which exerts a significant chlorine demand. Limits of chlorine demand shall be as established by the Administrator.
   (j)   (1)   If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in (i) above, and which in the judgment of the Administrator may interfere with, pass through, or otherwise be incompatible with the wastewater facilities, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Administrator may:
         A.   Reject the wastes;
         B.   Require pretreatment to an acceptable condition for discharge to the public sewers;
         C.   Require control over the quantities and rates of discharge;
         D.   Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of (g), (h), and (i) above and Section 935.12.
      (2)   If the Administrator 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 Administrator and the Ohio Environmental Protection Agency in accordance with the Ohio Revised Code Chapter 6111.
   (k)   Grease, oil, and sand interceptors shall be provided when, in the opinion of the Administrator, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts as specified in (i) (3) 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. The municipal official responsible for the plumbing code shall determine the size and type of interceptor, and shall be responsible for having it installed and maintained.
   (l)   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.
   (m)   When required by the Administrator, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable structure, together with such necessary meters and other appurtenances, in the building sewer to facilitate the observation, sampling, and measurement of the wastes. Such structure, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Administrator. The structure shall be installed by the owner at his expense, and shall be maintained by him so as to be safe and accessible at all times.
   (n)   The Administrator may require a user of sewer services to provide information needed to determine compliance with this chapter. These requirements may include:
      (1)   Wastewaters discharge peak rate and volume over a specified time period.
      (2)   Chemical analyses of wastewaters.
      (3)   Information on raw materials, processes, and products affecting wastewater volume and quality.
      (4)   Quantity and disposition of specific liquid, sludge, oil, solvent, or other materials important to sewer use control.
      (5)   A plot plan of sewers of the user's property showing sewer and pretreatment facility location.
      (6)   Details of wastewater pretreatment facilities.
      (7)   Details of systems to prevent and control the losses of materials through spills to the municipal sewer.
      (8)   Such other information and may be required by the Municipality's NPDES permit.
   (o)   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. All tests shall conform to EPA Regulation 40 CFR 136, published October 16, 1973 in the Federal Register entitled "Guidelines Establishing Test Procedures for Analysis of Pollutants." Sampling methods, location, times, durations, and frequencies are to be determined on an individual basis, subject to approval by the Administrator and other regulatory agencies.
   (p)   No statement contained in this section shall be construed as preventing any special agreement or arrangement between the Municipality and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the Municipality for treatment. Any user who enters into a special agreement or arrangement with the Municipality shall be subject to all user and industrial cost recovery charges as set forth herein. No special agreement will be entered into which is in conflict with § 307 of Public Law 92-500 or with any other state or federal law or regulation.
