No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of the POTW. These general prohibitions apply to all such users of the POTW whether or not the user is subject to national categorical pretreatment standards or any other national, state or local pretreatment standards or requirements. A user may not contribute the following substances to the POTW:
A. 
Any liquids, solids or gases which, by reason of their nature or quantity, are or may be sufficient, either alone or by interaction with other substances, to cause fire or explosion or be injurious in any other way to the POTW or to the operation of the POTW. At no time shall two successive readings on an explosion hazard meter at the point of discharge into the system (or at any point in the system) be more than 5% nor any single reading over 10% of the lower explosive limit (LEL) of the meter. Prohibited materials include but are not limited to gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides, sulfides, PCB's and any other substances which the Village, state or USEPA has notified the user is a fire hazard or a hazard to the system.
B. 
Solid or viscous substances which may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater treatment facilities, such as but not limited to grease, garbage with particles greater than 1/2 inch in any dimension, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, wastepaper, wood, plastics, gas, tar, asphalt residues, residues from refining or processing of fuel or lubricating oil, mud or glass grinding or polishing wastes.
C. 
Any wastewater having a pH less than 5.0 or greater than 9.5, unless the POTW is specifically designed to accommodate such wastewater, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment and/or personnel of the POTW.
D. 
Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the POTW or to exceed the limitation set forth in a categorical pretreatment standard. A toxic pollutant shall include but not be limited to any pollutant identified pursuant to § 307(a) of the Act.
E. 
Any noxious or malodorous liquids, gases or solids which either singly or by interaction with other wastes are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for their maintenance and repair.
F. 
Any substance which may cause the POTW's effluent or any other product of the POTW such as residues, sludges or scums to be unsuitable for reclamation and reuse or to interfere with the reclamation process where the POTW is pursuing a reuse and reclamation program. In no case shall a substance discharged to the POTW cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under § 405 of the Act; any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act or state criteria applicable to the sludge management methods being used.
G.

L. 
Any cyanide in excess of two milligrams per liter by weight as CN.
M. 
The admission into the public sewers of any waters or wastes having a five-day biochemical oxygen demand greater than 300 milligrams per liter; or containing more than 350 milligrams per liter of suspended solids; or containing any quantity of substances having the characteristics described in this section; or having an average daily flow greater than 2% of the average daily wastewater flow of the Village; or being of such nature and delivered at such quantity and quality and at such a rate as to impair the hydraulic capacity, strength or durability of the public sewers, structures, equipment or treatment plant shall be subject to the review and approval of the Engineer. Where, in the opinion of the Engineer, the water or waste admitted to the system may have a deleterious effect upon the wastewater treatment plant, process equipment or receiving waters or which otherwise may create a hazard to life or constitute a public nuisance, the Engineer shall:
(1) 
Advise the user(s) of the impact of the contribution on the POTW.
(2) 
Develop effluent limitation(s) for such user to correct the interference with the POTW and:
(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.
(d) 
Require payment to cover additional cost to handle and treat the wastes not covered by existing taxes or sewer charges.
N. 
Unpolluted water such as stormwater, roof drains, spring water, cistern overflow, footing drains or discharge from air-conditioning units, refrigeration units or heat pumps; or the contents of any privy vault, septic tank or cesspool except under such conditions and at such locations as are permitted by the Engineer.
A. 
Grease, oil and sand interceptors shall be provided when the above set limits for those substances are exceeded or when, in the opinion of the Engineer, they are necessary for the 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 which do not provide restaurant-type services. All interceptors shall be of a type and capacity approved by the Commission and shall be located so as to be readily and easily accessible for cleaning and inspection.
B. 
Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperatures. They shall be of substantial construction, watertight and equipped with easily removable covers which, when bolted in place, shall be gastight and watertight.
C. 
Where installed, all grease, oil and sand interceptors shall be maintained by the owner, at his expense, in continuously efficient operation and shall be readily accessible and open to inspection by the Engineer at any time.
Where pretreatment or flow-equalizing facilities are provided or required for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner(s), at his expense.
When required by the Engineer, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable structure together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such structure, when required, shall be accessibly and safely located and shall be constructed in accordance with plans approved by the Engineer and in concert with § 129-52. The structure shall be installed by the owner at his expense and shall be maintained by him so as to be safe and accessible at all times.
The Engineer may require a user of sewer services to provide information needed to determine compliance with this chapter. These requirements may include:
A. 
Wastewater discharge peak rate and volume over a specified time period.
B. 
Chemical analyses of wastewaters.
C. 
Information on raw materials, processes and products affecting wastewater volume and quality.
D. 
Quantity and disposition of specific liquid, sludge, oil, solvent or other materials important to sewer use control.
E. 
A plot plan of sewers on the user's property showing sewer and pretreatment facility location.
F. 
Details of wastewater pretreatment facilities.
G. 
Details of systems to prevent and control the losses of materials through spills to the municipal sewer.
A. 
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. Sampling methods, location, times, durations and frequencies are to be determined on an individual basis subject to approval by the Engineer.
B. 
No statement contained in this chapter shall be construed as preventing any special agreement or arrangement between the Commission and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the Village for treatment, subject to payment therefor by the industrial concern.
C. 
Alternate methods for the analysis of industrial wastes may be used subject to mutual agreement between the Commission and the producer of such wastes. The frequency and duration of the sampling of any industrial waste shall not be less than once every three months for a twenty-four-hour period. However, more frequent and longer periods may be required at the discretion of the Commission.
Where the Village's wastewater treatment system achieves consistent removal of pollutants limited by federal pretreatment standards, the Village may apply to the approval authority for modification of specific limits in the federal pretreatment standards. "Consistent removal" shall mean reduction in the amount of a pollutant or alteration of the nature of the pollutant by the wastewater treatment system to a less toxic or harmless state in the effluent which is achieved by the system in 95% of the samples taken when measured according to the procedures set forth in § 403.7(c)(2) of (Title 40 of the Code of Federal Regulations, Part 403) General Pretreatment Regulations for Existing and New Sources of Pollution promulgated pursuant to the Act. The Village may modify pollutant discharge limits in the federal pretreatment standards if the requirements contained in 40 CFR 403.7 are fulfilled and prior approval from the approval authority is obtained.
State requirements and limitations on discharges shall apply in any case where they are more stringent than federal requirements and limitations or those in this chapter.
The Village reserves the right to establish by local law more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives presented in § 129-2 of this chapter.
No user shall ever increase the use of process water or in any other way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the federal categorical pretreatment standards or in any other pollutant-specific limitation developed by the Village or state.
Each user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this chapter. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner's or user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the Commission for review and shall be approved by the Commission before construction of the facility. All existing users shall complete such a plan by January 1, 1983. No user who commences contribution to the POTW after the effective date of this chapter shall be permitted to introduce pollutants into the system until accidental discharge procedures have been approved by the Commission. Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify the user's facility as necessary to meet the requirements of this chapter. In the case of an accidental discharge, it is the responsibility of the user to immediately telephone and notify the POTW of the incident. The notification shall include location of discharge, type of waste, concentration and volume and corrective actions.
A. 
Written notice. Within five days following an accidental discharge, the user shall submit to the Engineer a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage or other liability which may be incurred as a result of damage to the POTW, fish kills or any other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties or other liability which may be imposed by this chapter or other applicable law.
B. 
Notice to employees. A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees whom to call in the event of a dangerous discharge. Employers shall ensure that all employees who may cause or suffer such a dangerous discharge to occur are advised of the emergency notification procedure.
