(2) Any pollutant which by reason of their nature or quantity, are or may be sufficient, either alone or by interaction, to cause safety hazards, fire or explosion or be injurious in any other way to the facilities or personnel of the village, or to the operation of village POTW. Materials considered in this regard are those with a closed cup flashpoint of less than 140º F. or 60º C. using the test methods specified in 40 CFR 261.21;
(3) Any solid, solid waste or viscous substance which will cause obstruction to the flow in a sewer or POTW, or other interference to the operation of the POTW. Prohibited materials include but are not limited to: waste cooking oil, grease, grease interceptor wastes, garbage with particles greater than one-half inch in any direction, 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 or hops, paper, wood, plastics, residues from gas, tar or asphalt, residues from refining or processing of fuel or lubricating oils, mud or glass grinding or polishing waste, fatty acids or esters of fatty acids, or any material which can be disposed of as trash;
(4) Any wastewater containing noxious or malodorous solids, liquids, or gases, which either singly or by their interaction are capable of creating a public nuisance or hazard to life, or to interfere with, inhibit or cause potential problems of any operation of the POTW, including but not limited to, prevention of entry into sewers for their maintenance and repair;
(5) Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems or which necessitates the village taking special measures to counteract and/or alleviate the impact of the pollutant(s);
(6) Any wastewater containing substances in sufficient quantity to interfere with the POTW;
(7) Any toxic pollutants in sufficient quantity, either singly or by interaction, to injure, interfere with or cause potential problems of any POTW treatment processes or facilities, constitute a hazard to humans or animals, or to exceed limitation as set forth in the existing Act, or the Act as it may be amended;
(8) Any wastewater having a temperature which shall inhibit biological activity or cause interference in the village's POTW facilities, but in no case heat in such a quantity that the influent temperature at the POTW will exceed 40º C. (104º F.);
(9) Any wastewater having a pH less than 5.0 or higher than 10 or having any other corrosive property capable of causing damage or hazard to structures, equipment or personnel in the POTW. The pH limits are instantaneous limits that shall be met at all times, and are not subject to averaging;
(10) Any pollutant, including oxygen demanding pollutants, released in a discharge at a flow rate and/or pollutant concentration (including any slug load), either singly or by interaction with other pollutants which may cause interference with, inhibit, or cause potential problems at the POTW;
(11) Ammonia nitrogen in amounts that would cause a violation of the water quality standards of the receiving waters of the POTW;
(12) Any wastes containing detergents, surface active agents, aqueous firefighting foam or other substances which may cause excessive foaming in the collection system or the treatment process that result in POTW interferences and/or pass through and/or is shown to inhibit the nitrification process. Wastes prohibited in this section shall not be processed or stored in such a manner that they could be discharged to the POTW;
(13) Additives for the purpose of emulsifying or biologically/chemically treating FOG for grease remediation or as a supplement to interceptor maintenance that have a content of enzymes, surfactants or solvents that is greater than 10% of the volume without the written consent of the Pretreatment Coordinator;
(14) Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass-through;
(15) Any wastewater containing any organism, including viruses, considered pathogenic and/or detrimental to POTW organisms other than by direct excrement and any other wastes defined as medical wastes;
(16) Any wastewater containing any radioactive wastes or isotopes, except in accordance with village, state and federal rules governing such discharges;
(17) Wastewater or wastes containing iron pickling wastes or concentrated plating solutions whether neutralized or not;
(18) Any leachate, groundwater remediation wastewater or waste material, originating within the POTW service area, which does not meet discharge limitations as set forth in this chapter or determined by this chapter except at discharge points designated by the Pretreatment Coordinator;
(19) All trucked or hauled wastes;
(20) Any bio-solids, screenings or other residues from the pretreatment of non-residential wastes;
(21) Any solid, solid waste or viscous substances that have caused an obstruction to the flow in a sewer that is eliminated by a professional service or contractor;
(22) 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) that cause potential problems or interfere with POTW operations;
(23) Any substance with objectionable color which is not removed in the treatment processes, such as, but not limited to: dye waste, ink waste and vegetable tanning solutions;
(24) Any substances that inhibit the use of UV for disinfection purposes;
(25) Wastewater or wastes containing substances which are not amenable to treatment or reduction by the POTW treatment processes employed, or are amenable to treatment only to such degree that the POTW effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters;
(26) Any substance or combination of substances which shall cause the POTW to be in violation of its NPDES permit(s), or to cause the village's POTW to violate receiving stream water quality and/or general effluent discharge standards;
(27) Any wastewater causing the POTW effluent to fail a toxicity test; or
(28) Any substance which may cause the village's POTW effluent or bio-solids, to be unsuitable for reclamation and re-use, or interfere with the reclamation processes. In no case shall a substance discharged to the village's POTW cause the village to be in noncompliance with any bio-solids use or disposal regulations developed under Section 405 of the Act; or any regulations affecting bio-solids use or disposal developed pursuant to the Resource Conservation and Recovery Act, Solids Waste Disposal Act, Toxic Substance Control Act, or any state or local standards applicable to any bio-solids management methods either being used, or considered by the village.
(D) Wastes prohibited in this section shall not be processed or stored in such manner that they could be discharged or introduced to the POTW. All users with prohibited wastes described in this section or those that have hazardous wastes as defined in § 13-10-9 shall develop and implement a Spill Prevention/Slug Control Containment and Countermeasures Plan consistent with the requirements in § 13-7-4. The Pretreatment Coordinator may also determine spill prevention/slug control is required of liquids and solids not previously described on either list based on an evaluation of a site potential to cause spills or slug loads to be introduced to the POTW. Notice requirements shall be permanently posted as provided in §§ 13-7-4 and 13-10-7. Spill planning applies to all users not just classified SIU or regulated NSRU.
