(a) No person shall discharge, or cause to be discharged, any storm water, surface water, ground water, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary sewer.
(b) Storm water, surface drainage, subsurface drainage, ground water, roof runoff, cooling 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 local authorities. Industrial cooling water or unpolluted process waters may be discharged, on approval of the local authorities, to a storm sewer or natural outlet.
(c) Anyone proposing to discharge any pollutant, including non-contact cooling water, to the waters of the State must submit an NPDES permit application to the Ohio EPA no later than 180 days prior to any discharge.
(d) No person shall be permitted to connect to or discharge wastewater into the sewerage system, unless it has been determined by the Authority that there is sufficient capacity in the system to collect, convey and treat the proposed wastewater discharge of such person.
(e) No person shall discharge or cause to be discharged, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of the POTW. These general prohibitions apply to all users of the POTW, whether or not the user is subject to National Categorical Pretreatment Standards (40 CFR Part 403) or any other Federal, State or local pretreatment standards or requirements.
(f) No person shall discharge or cause to be discharged any of the following described substances, materials, waters or wastes into any public sewers:
(1) 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 which exceeds 150 degrees Fahrenheit, or which causes the temperature of the wastewater at the treatment facility to exceed 104 degrees Fahrenheit.
(2) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive 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.
(3) Any water or wastes containing fats, waxes, free oils, emulsified oils and grease exceeding an average of fifty parts per million (417 pounds per million gallons) of ether soluble matter or containing substances which may solidify or become viscous at temperatures between thirty-two degrees Fahrenheit and 150 degrees Fahrenheit.
(4) Any waters or wastes 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 sewage treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the sewage treatment plant, including cyanides.
(5) Any garbage that has not been properly shredded to a degree that all particles will be carried freely under the flow conditions of the sewer and with no particle greater than one-half inch in any direction. The installation and operation of any garbage grinder with a motor of three-quarters Hp or larger shall be subject to the approval of the Authority.
(6) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch manure, hair and fleshings, entrails, lime slurry, lime residues, chemical residues, paint residues, cannery waste, bulk solids or any other solid or viscous substance capable of causing obstruction to the flow in sewers or other interference with proper operation of the sewerage works.
(7) Any waters or wastes containing suspended solids (SS) of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant, or any substance which may cause the POTW's effluent or treatment residues, sludges, or scums to be unsuitable for reclamation and reuse, or to interfere with the reclamation process.
(8) Any noxious or malodorous gases or substances capable of creating a public nuisance or hazard to life, or substances causing the release of noxious or poisonous gases after discharge into the public sewer system.
(9) Any waters or wastes containing strong acid iron pickling wastes or concentrated plating solutions, whether neutralized or not.
(10) Any waters or wastes containing substances which may cause the treatment plant to exceed NPDES permit limitations.
A. Industrial waste shall not exceed the limits for the materials listed below based on a twenty-four hour composite sample, or as may be established by the Authority from time to time for such materials to meet NPDES permit conditions.
Effluent Characteristics | Discharge Limitation, (mg/l) |
Effluent Characteristics | Discharge Limitation, (mg/l) |

B. The preceding list of substances is subject to revisions as required to meet current water quality standards or effluent standards imposed by State or Federal agencies.
C. In special cases (low volume users), the concentration of the applicable substances in the wastewater may be exceeded if it is determined by the Authority that the total pounds of the substances discharged to the sewerage system are not harmful to or will not interfere with the sewage treatment process or will not violate water quality or effluent standards.
(11) Any waters or wastes containing phenols or other taste or odor-producing substances, in concentrations exceeding limits which may be established by the Authority as necessary, after treatment of the composite sewage, to meet the requirements of Federal, State or other public agencies of jurisdiction for such discharge to the receiving waters, and which might cause the POTW to violate its NPDES permit and/or other disposal system permits.
(12) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Authority in compliance with applicable State or Federal regulations.
(13) Any waters or wastes having a pH of less than 5.5 or in excess of 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment or personnel of the sewerage system.
(14) Materials which exert or cause:
A. Unusual concentrations of inert suspended solids such as, but not limited to, fuller's earth, lime slurries and lime residues, or of dissolved solids such as, but not limited to, sodium chloride and sodium sulfate.
B. Excessive discoloration such as, but not limited to, dye wastes and vegetable tanning solutions.
C. Biochemical oxygen demand, suspended solids or chlorine requirements in such concentrations as to constitute a load on the sewage treatment works greater than that expected from normal domestic wastewater characteristics.
D. Unusual volume of flow or concentration of wastes constituting slugs.
(15) Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed or which are amenable to treatment only to such a degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
(g) No discharger shall dilute a waste stream as a substitute for adequate treatment to achieve compliance with the standards set forth in this chapter.
(h) The National Categorical Pretreatment Standards, as established by the U.S. EPA, shall be met by all discharges of the regulated industrial categories. If a pollutant in an industrial discharge is limited by both National Categorical Pretreatment Standards and limits established by the Authority, the maximum allowable concentration will be the more stringent of the two.
(i) If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substance or possess the characteristics which, in the judgment of the Authority, may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which may otherwise create a hazard to life or constitute a public nuisance, the Authority may:
(1) Reject the wastes;
(2) Require pretreatment to an acceptable condition in accordance with guidelines adopted herein for discharge into the public sewers;
(3) Require control over quantities and rates of discharge; and/or
(4) Require payment of a surcharge to cover the added cost of handling and treatment of the wastes not covered by existing taxes or sewer charges.
(j) If the Authority 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 Authority and subject to the requirements of all applicable Federal, State and local codes, regulations and laws.
(k) No person shall discharge septic tank wastes or other similar wastes into the Authority's treatment system without first obtaining written approval from the Authority prior to such discharge. Septic tank wastes and other similar wastes shall not be discharged to sewers tributary to the Authority's treatment plant unless the Authority has granted permission to do so.
(l) The Authority may refuse the services of its facilities for septic tank or other similar waste materials if the waste is determined to:
(1) Be deleterious to the treatment plant or appurtenances thereto;
(2) Cause unusual expense in the handling of the treatment thereof;
(3) Inhibit the performance of the treatment process; and
(4) Cause the plant to violate its NPDES permit and/or other disposal system permits.
(m) Treatment charges for septic tank wastes delivered by an approved hauler shall be based on a flat rate for each load of 1,000 gallons or portion thereof, as defined in Appendix A.
