(a) The Public Service Director shall enforce rules and regulations establishing the types and characteristics of sewage, industrial wastes, and other matters which shall be discharged into the sanitary sewerage system, the types and characteristics of sewage and industrial wastes admissible to the system only after pretreatment, requisites for pretreatment, and otherwise governing the discharge of sewage, industrial wastes, and other matters into the system in the interest of safety and efficient operation of the wastewater treatment plant. Applicable industrial pretreatment conditions and industrial pretreatment regulations, as promulgated under Section 307(b) of the Clean Water Act, are hereby incorporated in this chapter and made a part thereof.
(b) An industry shall, upon application for sewer service, present to the Public Service Director a tabulation of the chemical analysis of the wastes to be discharged to sewerage system and the volume of such wastes, or if this is not available, the expected waste analysis based on similar processes now in operation.
(c) In cases where the character of sewage or industrial waste from any manufacturing or industrial plant, building, or premises is such that it will damage the sewerage system or cannot be treated satisfactorily at the wastewater treatment plant, the Public Service Director shall compel such users to dispose of such waste in an approved alternative manner and prevent it from entering the sewerage system.
(d) In cases where the character of the sewage or industrial waste from any manufacturing or industrial plant, building, or premises is such that it imposes an unreasonable burden upon the sewage collection, pumping, or treatment works greater than that imposed by the average sewage entering the sewerage system, the Public Service Director may: compel such manufacturing or industrial plant, building, or premises to pretreat such sewage in such manner as specified by the Public Service Director before discharging it into the sewerage system; require flow control or equalization of such wastes so as to avoid any “slug” loads or excessive loads that may be harmful to the treatment works, or require payment of a surcharge on any excessive flows or loadings discharged to the treatment works to cover the additional costs of having capacity for and treating such wastes.
(e) National categorical pretreatment standards as promulgated by the U.S. Environmental Protection Agency pursuant to the Clean Water Act shall be met by all industrial users subject to such standards.
(f) State requirements and limitations on discharges to the POTW shall be met by all Dischargers which are subject to those standards in any instance in which they are more stringent than federal requirements or those in this chapter.
(g) No user shall discharge wastewater in excess of the following limitations.

The preceding list of pollutants is subject to revisions as required to meet current water quality standards or effluent standards imposed by state or federal agencies.
(h) No person shall discharge or cause to be discharged, either directly or indirectly to the sewerage system, any of the following described substances, material, waters, or wastes:
(1) Heat in amounts sufficient to inhibit biological activity, but in no case wastewater exceeding 104° F.
(2) Any gasoline, benzene, naphtha, fuel, oil, mineral oil, or other volatile flammable or explosive liquid, solid, or gas which may create a fire or explosion hazard in sewers or at the POTW, but in no case wastewater with a closed cup flashpoint of less than 140°F.
(3) Any noxious or malodorous gas or substance which, either singly or by interaction with other wastes, is capable of creating a public nuisance or hazard to life or of preventing entry into the sewers for their maintenance and repair.
(4) Any waters or wastes having a pH lower than 5.5 or higher than 9.0, or having any other corrosive property capable of causing damage or hazard to structures, equipment, or personnel of the sewerage system.
(5) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, paunch manure, hair and fleshing, entrails, lime slurry, lime, chemical or paint residues, cannery wastes, bulk solids, or any other solid objects or viscous substance capable of causing obstruction to the flow operation of the sewerage system.
(6) Any waters or wastes containing a toxic or poisonous substance in sufficient quantity to injure or interfere with any sewerage treatment process, constitute a hazard to humans or animals, or create any hazard in the receiving waters of the sewerage system.
(7) Any water or wastes containing emulsified oil or grease exceeding, on analysis, an average of 50 milligrams of oil and grease per liter determined as total soluble matter.
(8) 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 ½ inch in any dimension.
(9) Any water or wastes containing suspended solids of such character or quality that unusual attention or expense is required to handle such materials at the sewage treatment plant, or having a chlorine demand greater than 25 parts per million.
(10) Any waste containing substances that would result in a violation of the NPDES permit.
(11) Any substance with objectionable color such as, but not limited to, dyes and tanning solutions.
(12) Any unpolluted waters which will increase the hydraulic loading on the POTW including, but not limited to, any stormwater, surface water, groundwater, roof runoff water, subsurface drainage, uncontaminated cooling water, or uncontaminated industrial process waters.
(13) Any trucked or hauled pollutants, including septage and industrial waste, except as may be approved by the Public Service Director.
(14) Any of the above list is subject to revisions as required to meet current water quality standards imposed by the state or federal agencies.
(i) No statement contained in this section shall be interpreted 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. In all such cases, the provisions set forth in the Village Ordinance establishing Sewer Service Charges (Chapter 933 of these Codified Ordinances) will be governing factors in any contracts entered into.
(j) Grease, oil, and sand interceptors shall be provided when, in the opinion of the Village, they are necessary for proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand, and other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be located as to be readily and easily accessible for cleaning and inspection. Grease and oil 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. Where installed, all grease, oil, and sand interceptors shall be maintained by the owner at his expense, in continuous efficient operation at all times. (Ord. 99051. Passed 8-16-99.)
