(A) No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
(1) Any gasoline, benzene, naptha, fuel oil or other inflammable or explosive liquid, solid or gas or noxious or malodorous liquids, gases or solids, which either alone or by interaction are capable of creating a public nuisance or hazard to life, or are sufficient to prevent entry into the sewers for their maintenance and repair;
(2) Any waters or wastes having a pH lower than 5.0 or higher than 9.0, or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works;
(3) Solid or viscous substances which will or may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater system; or
(4) Any substance which causes a pass through.
(B) No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes, which shall include, but not be limited to, the substances set out as follows:
(1) Any liquid or vapor having a temperature higher than 160°F or with a temperature which will inhibit biological activity in the wastewater treatment plan resulting in interference; but in no case, wastewater with a temperature which will cause the raw wastewater in the affluent to the wastewater treatment plant to exceed 140°F;
(2) Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of 50 mg/l of which not more than 25 mg/l is soluble oils, or containing substances which may solidify or become so highly viscous as to retard flow in the sewer system at temperatures between 32° and 150°F (0° and 65°C);
(3) Any garbage that has not been properly shredded. Installation and operation of any garbage grinder (other than in a residence) may be subject to the review and approval of the Superintendent;
(4) Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions whether neutralized or not;
(5) Any water or wastes exceeding the following maximum allowable limits:

Zinc | 6.8 | 3.4 | 1.5 |
(6) Objectionable or toxic substances or wastes exerting an excessive chlorine requirement to such degree that any such material received in the composite sewage at the treatment works exceeds the limits established by the Superintendent for such materials by state, federal or other public agencies of jurisdiction;
(7) Any waters or wastes containing phenols or other taste- or odor-producing substances after treatment of the composite sewage, in such concentrations exceeding limits which may be established by the Superintendent as necessary to meet the requirements of the state, federal or other public agencies of jurisdiction for such discharge to the respective waters;
(8) Any radioactive material in excess of limits established by state and federal law;
(9) Any waters or wastes having a pH of less than 5.0 or in excess of 9.0;
(10) Materials which exert or cause:
(a) Unusual concentrations of inert, suspended solids (such as but not limited to Fullers earth, lime slurries and lime residues) or dissolved solids (such as but not limited to sodium chloride and sodium sulfate);
(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 plant; or
(d) Unusual volume of flow or concentration of wastes constituting “slugs” as defined herein.
(11) 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;
(12) Any substance which will cause the wastewater works to violate its NPDES permit or the receiving stream’s water quality;
(13) Any wastewater containing toxic pollutants in sufficient quantity either singularly or in 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 water of the wastewater plant or to exceed applicable categorical pretreatment standards; and/or
(14) Any substance which will cause the wastewater treatment plant to violate its NPEDS permit or the receiving stream’s water quality standards.
(C) If any waters or wastes are discharged, or are proposed to be discharged, to the public sewers, which waters contain the substance or possess the characteristics enumerated in division (B) above, and which in the judgment of the Town Council may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Town Council shall:
(1) Require new industries, or industries with significant increase in discharges, to submit information on wastewater characteristics and obtain prior approval for discharges;
(2) Require other methods of disposal;
(3) Require pretreatment to an acceptable condition for discharge to the public sewers;
(4) Require control over the quantities and rates of discharge; and/or
(5) (a) Each discharger shall provide protection from accidental discharge of substances regulated by this chapter. Where necessary, facilities to prevent accidental discharge of prohibited materials as defined in divisions (A) and (B) above shall be provided and maintained at the discharger’s cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the Authority for review and shall be approved by the Authority before construction of the facility. Each existing discharger shall complete its plan and submit same to the Authority by 60 days from the effective date of this chapter. No discharger who discharges to the POTW after the aforesaid date shall be permitted to introduce pollutants into the system until accidental discharge protection procedures have been approved by the Authority. Review and approval of such plans and operating procedures by the Authority shall not relieve the discharger from the responsibility to modify its facility as necessary to meet the requirements of this chapter.
(b) Dischargers shall notify the Authority immediately upon the occurrence of a slugload, or accidental discharge of substances prohibited by this chapter. The notification shall include location of discharge, date and time thereof, type of waste, concentration and volume and corrective actions.
(c) Any discharger who discharges a slugload of prohibited materials shall be liable for any expense, loss or damage to the POTW and for any loss for fish kill or any other damage to person or property, in addition to the amount of fines imposed on the Authority on account thereof under state or federal law. An additional report with updated information as required above shall be filed within five working days of the initial report. Signs shall be permanently posted in conspicuous places on discharger’s premises, advising employees of who to call in the event of a slug or accidental discharge. Employers shall instruct all employees who may cause or discover such a discharge with respect to emergency notification procedure. The telephone number of the POTW shall be prominently posted at the industry and the discharger shall notify the POTW of any slug discharge.
