A. No person(s) shall discharge or cause the discharge of any unpolluted waters such as storm water, surface water, ground water, roof runoff, subsurface drainage, or cooling water to any sewer. Storm water runoff from limited areas, which storm water may be polluted at times, may be discharged to the sanitary sewer by permission of the city and Utah department of environmental quality.
B. Storm water and other than that exempted under the previous paragraph and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers, or to natural outlets approved by the city and the Utah department of environmental quality. Unpolluted industrial cooling water or process waters shall also be discharged to a storm sewer or natural outlet.
C. No person(s) shall discharge or cause to be discharged any of the following described water liquids or wastes to any public sewer: 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 other wastes, to contaminate or interrupt any sewage treatment process, constitute a hazard in or have an adverse effect on the waters receiving any discharge from the works; 3) any waters or wastes having a pH lower than 5.5 or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the wastewater works; and 4) solid or viscous substances in quantities or 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, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, underground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders. Each person or user which discharges any toxic pollutants which cause an increase in the cost of managing the effluent of the sludge of the wastewater treatment works shall pay for such increased costs.
D. The following described substances, materials, waters, or wastes shall be limited in discharges to municipal system to concentrations or quantities which will not harm either the sewers, the sludge of any municipal system, the wastewater treatment process or equipment, will not have an adverse effect on the receiving stream, or equipment, will not have an adverse effect on the receiving stream, or will not otherwise endanger lives, public property or constitute a nuisance. The city may set limitations below if such more severe limitations are necessary to meet the above objectives. In setting these requirements, the city 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 sewers, capacity of the wastewater treatment plant, and other pertinent factors. The limitations or restrictions on materials or characteristics of waste or wastewaters discharged to the sanitary sewer which shall not be violated without approval of the city are as follows:
1. Wastewater having a temperature higher than one hundred fifty degrees Fahrenheit (150°F) (65 degrees Celsius).
2. Wastewater containing more than twenty five milligrams per liter (25 mg/l) of petroleum oil, nonbiodegradable cutting oils, or products 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 in commercial kitchens for the purpose of consumption on the premises.
5. Any waters or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances to such degree that any such material received in the composite wastewater at the wastewater treatment works exceeds the limits established by the state of Utah and the environmental protection agency for such materials.
6. Any waters or wastes containing odor producing substances exceeding limits which may be established by the state of Utah and the environmental protection agency.
7. Any radioactive wastes or isotopes of such half life of concentration as may exceed limits established in compliance with applicable state or federal regulations.
8. Quantities of flow, concentrations, or both which constitute a "slug" as defined herein.
9. Water or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed or are amendable 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 system, release obnoxious gases, form suspended solids which interfere with the collection system, or create a condition deleterious to structures and treatment processes.
E. If any water or wastes are discharged, or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated above, and which are determined by the city to have a deleterious effect upon the wastewater facilities, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the city may:
1. Reject the wastes;
2. Require pretreatment in accordance with Spanish Fork's public sewer system pretreatment regulations;
3. Require control over the quantities and rates of discharge, and/or wastes not covered by existing taxes or sewer charges under the provisions of this chapter. If the city permits the pretreatment of equalization or waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the city and the Utah state department of environmental quality.
4. A plot plan of sewers of the user's property showing sewer and pretreatment facility location.
5. Details of wastewater pretreatment facilities.
6. Details of systems to prevent and control the losses of materials through spills to the municipal sewer.
F. All measurements, tests, and analysis 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 Waste Water", 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 city.
G. No statement contained in this chapter shall be construed as preventing any special agreement or arrangement between the city and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the city for treatment.
H. No persons shall maliciously, wilfully, or negligently break, destroy, uncover, deface, or tamper with any structure, appurtenances or equipment which is a part of the wastewater facilities. Any persons violating this provision shall be subject to immediate arrest and charged according to law. (Ord. 95-19)
