(A) Generally. The written permission to construct a house sewer or to make a connection to a public sewer shall specify the permissible use of such house sewer and connection and such specifications shall be governed by the following requirements.
(1) Sewage, including wastes from water closets, urinals, lavatories, sinks, bath tubs, laundries, cellar floor drains, bars, soda fountains, cuspidors, refrigerator drips, drinking fountains, stable floor drains and other objectionable wastes shall be discharged into a sanitary or combined sewer but in no case into a storm sewer.
(2) Industrial waste shall not be discharged into a storm water sewer but may be discharged into a sanitary sewer if the waste is of such character as not to be detrimental to the sewer system or to the sewage treatment works.
(3) Where such waste is detrimental to the sewer system or sewage treatment works it shall be otherwise disposed of in a satisfactory manner or so improved in character as not to be detrimental to the sewer system or sewage treatment works.
(4) Surface water, rain water from roofs, subsoil drainage, building foundation drainage, cistern overflow, clean water from condensers, waste water from water motors and elevators, and any other clean and unobjectionable waste water shall be discharged into a storm water but in no case into a sanitary sewer.
(5) Connection with a cesspool or a privy vault shall not be made into a sanitary or storm water sewer.
(6) A trap for the interception of grease and oil shall be provided on a connection from a hotel restaurant, club or institutional kitchen and from a public garage or motor vehicle washing station. Such trap shall be satisfactory to the Village Administrator. No person shall discharge into a house sewer or tap a house sewer for the purpose of discharging into it any waste or drainage water prohibited by the provisions of this section. Any existing connection in violation of the provisions of this section shall be abandoned and removed.
(B) Action when discharged substances have a deleterious effect. If any substances discharged or proposed to be discharged into a Public Owned Treatment Works under the control of the village, where such substances may, in the judgment of the Village Administrator, have a deleterious effect upon the POTW, treatment processes or receiving waters, including violation of applicable water quality standards, or which otherwise may create a hazard to health, safety, welfare or the environment, or increase the cost of operating the POTW, the Village Administrator may:
(1) Require immediate cessation of the discharge;
(2) Revoke or suspend the administrative order authorizing the discharge;
(3) Require pretreatment or additional pretreatment;
(4) Limit the quantities and/or rates of discharge; and/or
(5) Require payment for the added cost of handling and treating the substances.
(C) Industrial discharges. All industrial wastes discharged to the POTW shall, at a minimum, meet the most stringent requirements of applicable national categorical pretreatment standards, or best practical control technology currently available for incompatible pollutants, as prescribed in the Code of Federal Regulations.
(D) Discharge prohibitions. No person shall discharge or cause to be discharged, directly or indirectly, any of the following substances or classes of substances into the POTW:
(1) Any storm water, roof runoff, surface water, ground water or other subsurface drainage or non-contact cooling water;
(2) Any substance which may create a fire or explosion hazard in the POTW, including but not limited to substances with a closed cup flashpoint of less than 140°F or 60°C using the test method specified in 40 C.F.R. Part 261.21. Prohibited materials include but are not limited to gasoline, kerosene, naphtha, benzene, fuel oil, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides;
(3) Any solid or viscous substance in quantities or of a size that may cause obstruction to the flow in a sewer or interference or pass through the POTW including, but not limited to: medical wastes, grease, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails, blood, feathers, ashes, cinders, sand, mud, spent lime, stone or marble dust, wood, metal, glass, plastics, shavings, straw, grass clippings, rags, spent grains, waste paper, paper products, gas, tar, asphalt residues, residues from the refining or processing of fuel or lubricating oil, or lens grinding or polishing wastes;
(4) Any garbage, unless originating from residences used for noncommercial purposes, which has not been shredded such that no particle is greater than one-half inch in any dimension. Garbage grinders shall not be connected to the POTW from hotels, institutions, restaurants, hospitals, groceries, catering establishments or similar places where garbage originates from the commercial or large-scale preparation of food for the purpose of sale, consumption on the premises, or for service by caterers;
(5) Any petroleum oil, non-biodegradable cutting oils, products of mineral oil origin, or floatable oils, fat, wax or grease, that pass through the POTW or cause interference. In no event shall the total concentration of such substances exceed 250 mg/l;
(6) Any substance having a pH less than 5.0 or greater than 10.0, or having any other corrosive property capable of causing damage or hazard to structures, equipment or personnel of the POTW. The Village Administrator may impose more stringent pH limits on any user where he or she determines that such limits are necessary to avoid an adverse impact on the POTW, treatment processes, sludge disposal methods or violation of NPDES permits;
(7) Any substance that either singly or by interaction with other substances, may create a public nuisance, a hazard to human life or health, or prevent or interfere with entry into the sewerage system for maintenance and repair;
(8) Any substance that may cause a treatment plant effluent or any other product of the treatment plant, such as residues, sludges or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation process;
(9) Any substance that may cause a treatment plant to violate any applicable sludge use or disposal statute, regulation, guideline or criterion;
(10) Any substance which may cause a treatment plant to violate its NPDES permit or cause a violation of water quality standards;
(11) Any substance, the color of which is not completely removed in the treatment process, including but not limited to dye wastes and vegetable tanning solutions;
(12) Any substance the temperature of which may inhibit biological activity in a treatment plant or interfere with wastewater treatment process efficiency. At no time shall any discharge into the POTW exceed 120°F (49°C) or cause the wastewater at a treatment plant to exceed 104°F (40°C);
(13) Any substance, including oxygen demanding materials (BOD and COD), at a rate and/or concentration that may cause interference or pass through at a treatment plant. No discharge shall have a flow rate or contain concentrations or quantities of pollutants that exceed, for any period of time longer than 60 minutes, during any 24-hour period, more than five times the permitted average 24-hour concentration, quantity or flow representative or normal operations;
(14) Any radioactive substance whose half-life or concentration exceeds limits established or prescribed by applicable federal or state requirement;
(15) Any substance that, either singly or by interaction with other substances, may injure or interfere with any wastewater treatment process, constitute a hazard to the life or health of humans or animals, create a public nuisance, may be toxic to any organism in the receiving water of a treatment plant or exceeds any limitation set forth in a pretreatment standard; and
(16) Any substance that may result in gases, vapors or fumes within the POTW that may endanger the health, safety or welfare of village employees.
(E) Evaluation and review. Before any application to use the sewer system is approved, a review of the proposed installation shall be reviewed by the Village Administrator to determine if the discharge is compatible with both the capacity and the capability for treatment of the proposed discharge.
(F) Monitoring manholes. If the discharge requires periodic sampling to assure allowable discharge, a monitoring manhole must be installed between the building sewer and the public sewer. Such manhole must be available for sampling without prior notice.
(G) System capacity. In no case will a new user or increased release into the system from a present user be permitted that is in excess of the capacity of the system. This capacity is determined not only by the capacity of the final plant destination and discharge permit, but also the capacity of the piping within the system, lift stations, surge tanks or any other component of the system.
(H) Flow meters. If for any reason the system has the capability of discharging an amount of effluent into the system that could be in excess of the domestic water meter reading, the system will be required to have a flow meter installed between the building sewer and the public system.
(I) Sampling and testing. Sampling and testing of discharges into the public system shall be made by the Sewer Department any time there is a reason to believe the approved discharge has changed. If found to vary from the original approval, appropriate action shall be taken to bring the discharge into compliance.
