No person(s) shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers or treatment works:
(A) Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive liquid, solid or gas.
(B) Any waters or wastes having a pH lower than 6.0 higher than 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the wastewater works.
(C) Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers or other appurtenances 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, plastic, wood, un-ground garbage, whole blood, paunch manure, entrails, and paper dishes, cups, milk containers, etc. either whole or ground by garbage grinders.
(D) Wastewater having a temperature higher than 120° Fahrenheit.
(E) Any water or waste containing any toxic or poisonous substance in sufficient quantity to interfere with the village's wastewater treatment process or constituting a hazard to humans or animals, or causing any violation of discharge standards in local receiving streams.
(F) Any waters or wastes containing suspended solids of such character or concentration that unusual attention, treatment, or expense is required at the wastewater treatment plant.
(G) 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.
(H) (1) Wastewater containing more than 50 milligrams per liter of petroleum oil, non-biodegradable cutting oils, products of mineral oil origin, or floatable oils, fat, wax, or grease in excess of 100 mg/l as determined by the currently approved test for total recoverable fats and grease as listed in 40 C.F.R. § 136.3 . Floatable oil and grease (FOG) interceptors shall be provided when, in the opinion of the Administrator, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, flammable wastes, or other harmful ingredients; except that the interceptors shall not be required for private living quarters or dwelling units. The FOG interceptor shall be installed on a separate building sewer servicing kitchen flows only which would allow fats oils and grease to be discharged through the interceptor. This shall include all pot sinks, pre-rinse sinks, any other sinks into which oils and grease are likely to be introduced, floor drains into which kettles may be drained, automatic hood wash units, dishwashers or any other fixtures or facilities where oils, fats and grease is likely to be discharged. No food grinders or garbage disposals may be connected to the FOG interceptor.
(2) All FOG interceptors shall be watertight and be constructed of pre-cast concrete or other similar durable material and shall be so located to be accessible for convenient inspection, cleaning and maintenance.
(3) FOG interceptors shall have a minimum detention time of at least 24 hours at maximum daily flow and shall have a minimum liquid depth of 36 inches measured from the bottom of the tank to the outlet. The air space from the top of the liquid to the underside of the tank shall be a minimum of eight inches. They shall be equipped with easily removable covers which, when bolted in place, shall be gas tight and water tight. All grease and oil interceptors shall be maintained by the owner, at his or her expense, in continuously efficient operation at all times.
(I) Any (unpolluted) surface water, groundwater, roof runoff, storm water, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process waters to any sanitary sewer. Any existing roof drain connections to sanitary or combined sewers shall be connected into an available storm sewer or shall be discharged above ground in an appropriate manner approved by the village. Discharges from roof drains emptying onto the surface of the ground shall be at least three feet from adjacent property lines, and shall in no way be directed so as cause flooding or otherwise damage adjoining property. The owner of any building(s) situated within the village is required at his or her expense to disconnect all existing roof drains from sanitary and combined sewers in accordance with the provisions of this section within 180 days after the date of official notice to do so. For any new construction, any storm water connections of roof drains; footer and foundation tiles or any other connection to a sanitary sewer is prohibited.
(J) Any water or wastes containing solids, liquids or gasses in sufficient quantity either singly or by interaction with other wastes to injure or interfere with any waste water treatment process or which constitute a hazard to humans, animals, or waters of the wastewater treatment plant, including, but not limited to, as shown below. These concentrations shall not be exceeded in industrial wastes discharged to the public sewers. These maximum concentrations may be changed as necessary by the Administrator or state regulatory agencies based on the new information concerning inhibitory substances or to protect treatment plant processes. Industrial dischargers covered by federal pretreatment requirements shall meet those limitations specified under the effluent guidelines published under Section 304(b) and 307(b) of the Federal Act or the below concentrations, whichever is more stringent.
(K) (1) Unusual volume of flow or concentrations of wastes constituting “slugs” as defined in these regulations.
(2) These concentrations shall not be exceeded in industrial wastes discharged to the public sewers.

(3) The admission into the public sewers of any waters or wastes having a five-day chemical biological oxygen demand greater than 200 milligrams per liter by weight or containing more than 200 milligrams per liter by weight of suspended solids or containing any quantity of substances having the characteristics described in the above divisions, or having an average daily flow greater than 10% of the average daily sewage flow of the village, shall be subject to the review and approval of the Administrator. The owner shall provide, at his or her expense, the preliminary treatment as may be necessary to reduce the chemical biological oxygen demand to 200 milligrams per liter by weight, or reduce objectionable characteristics of constituents to within the maximum limits provided above, or control the quantities and rates of discharge of the waters and waste. Plans and specifications and any other pertinent information relating to proposed treatment facilities shall be submitted for approval by the Administrative Director and the Ohio Environmental Protection Agency; and no construction of the facilities shall be commenced until this approval is obtained in writing. Where any treatment facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation, by the owner of the treatment facilities at his or her expense.
(4) If the concentration of any industrial waste exceeds the limits stipulated above, as received at the sewage treatment plant, the contributor shall reduce, by acceptable pretreatment and flow regulation or both, the amounts wasted to the public sewer until the aggregate of any such waste concentration at the treatment works shall not exceed the above prescribed limits.
