(b) Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions);
(c) Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works;
(d) Unusual volume of flow or concentration of wastes constituting “slugs” as defined herein;
(10) Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters;
(11) Any waters or wastes having a five-day BOD greater than 300 parts per million by weight; or containing more than 350 parts per million by weight of suspended solids; or having an average daily flow greater than 2% of the average sewage flow of the village, shall be subject to the review of the village. Where necessary in the opinion of the village, the owner shall provide, at his expense, such preliminary treatment as may be necessary to reduce the biochemical oxygen demand to 300 parts per million by weight; or reduce the suspended solids to 350 parts per million by weight; or control the quantities and rates of discharge of such waters or wastes. Plans, specifications, and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the village and no construction of such facilities shall be commenced until said approvals are obtained in writing.
(E) (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 division (D) of this section, and which in the judgment of the village may have a deleterious effect upon the sewage works, processes, equipment, or receiving waters, or which otherwise create a hazard to life to constitute a public nuisance, the village 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; and/or
(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 division (J) of this section;
(2) If the village 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 village and subject to the requirements of all applicable codes, ordinances and laws.
(F) Grease, oil, and sand interceptors shall be provided when, in the opinion of the village, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts or any flammable wastes, of sand, or of other harmful ingredients, except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be subject to the following requirements:
(1) All interceptors shall be located as to be readily and easily accessible for cleaning by the user and for inspection by the village;
(2) All interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight, and equipped with easily removable covers which when bolted in place shall be gastight and watertight;
(3) The owner shall ensure that all interceptors work properly and effectively;
(4) All interceptors shall fully comply with all applicable provisions of the Village Code of Ordinances and any other applicable village regulations;
(5) The owner shall be solely responsible for the cost and completion of interceptor cleaning, inspection, and maintenance, and repairs;
(6) Pumping of all interceptors shall be performed when, in the case of a grease interceptor the total volume of captured fats, oils, grease, and food sludge in a grease interceptor or, in the case of a sand and oil interceptor, the total volume of captured sand and oil displaces 20% or more of the volume of the interceptor. In no case shall pumping be performed less often than every two months. Pumping the interceptor means emptying it and cleaning the side walls, cross pipes, and inlet and outlet pipes.
(7) All interceptors shall be opened, inspected, and maintained a minimum of once per month;
(8) Interceptors may be inspected by the village as often as deemed necessary to assure compliance with this section. Such inspections may be unannounced. The village may review the facilities’ records on proper pumping, cleaning, maintenance, and disposal activities and may order the facility to make such changes or repairs as necessary to comply with the provisions of this section;
(9) The owner shall be solely responsible for the cost and completion of all repairs of interceptors. Repairs required by the village shall be completed within 21 calendar days from the date of receipt of written notice of required repairs;.
(10) The owner shall be responsible for the lawful and effective disposition of all grease, sand, oil, and materials removed from interceptors;
(11) The owner shall maintain records of all interceptor cleaning, maintenance, disposal, and repair, and shall make all records available to the village on demand. Such records shall include the date and time of the event recorded as well as the date the record was created and shall include the amount of material pumped, the repair conducted, or similar description of the recorded event. All records shall be signed by the authorized owner or operator, or a representative of the owner or operator. If cleaning and maintenance are done by facility owners, written maintenance and cleaning procedures as well as the above-required records are required and shall be made available to the village upon demand. All required written records shall be maintained for three years from the date the record was created;
(12) No grease, sand, or oil sources shall be connected directly to sewer lines or be allowed in any other manner to bypass the interceptor;
(13) Sewage shall not be allowed to pass through a interceptor;
(14) Access covers or manholes shall be clearly identifiable and provided over each interceptor. The manhole shall have readily removable covers to facilitate inspection, the removal of grease, sand, oil, and other materials, and gray water sampling activities. The location of the interceptor shall be kept free and clear of debris. Blocking or covering the access to manholes is prohibited. The owners or designated representatives (facility managers) of the food service facilities or transportation service establishments shall open access covers or manhole covers at the request of the village;
(15) Interceptors shall be designed and maintained so as to prevent surface water or groundwater from entering the interceptor through leaks in the plumbing or cracks in the interceptor itself;
(16) Under-the-sink grease interceptors shall be cleaned at a minimum of once per week, or more often as necessary, to prevent pass-through of grease and other solids into the village’s sewage system. Facilities with under the sink grease interceptors are subject to the same recordkeeping requirements as indicated above;
(17) The owner shall allow the village ready access at all reasonable times to all parts of the facility for the purpose of interceptor inspections, observations, records examination, measurements, sampling, testing, and any other function deemed necessary under this section.
(G) Where preliminary treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.
(H) When required by the village the owner of any property services by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling, and measurement of the wastes. Such manhole, when required, shall be accessible and safely located and shall be constructed in accordance with plans approved by the village. The manhole shall be installed by the owner at his or her expense and shall be maintained by him or her so as to be safe and accessible at all times.
(I) 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 and shall be determined at the control manhole provided or upon suitable samples taken at the control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb, and property. (The particular analyses involved will determine whether a 24-hour composite of all outfalls of a premise is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solid analyses are obtained from 24-hour composites of all outfalls whereas pHs are determined from periodic grab samples.)
(J) No statement contained in this section shall be construed as preventing any special agreement or arrangement between the village and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the village for treatment, subject to payment thereof, by the industrial concern.
(K) The village shall have the right to enforce the provisions of this section, to bring a cause of action for a violation of this section under § 10.99 of the village Code of Ordinances, and to bill the owner in violation of this section for the costs incurred by the village to bring any interceptor into compliance with this section.
