No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, or subsurface drainage to any public sanitary sewer.
Stormwater, groundwater, and all other unpolluted drainage, including unpolluted cooling or process water, shall be discharged to such sewers as are specifically designated as storm sewers, or drainage ditches, or to a natural outlet. Uncontaminated industrial cooling water or unpolluted industrial process waters may be discharged on approval of the Superintendent, the Niagara County Health Department and DEC to a storm sewer or natural outlet.
No person shall discharge or deposit or cause or allow to be discharged or deposited into the wastewater treatment system any wastewater which contains the following:
A. 
Explosive mixtures. Liquid, 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 wastewater treatment system or to the operation of the system. At no time shall two successive readings on an explosion hazard meter, at the point of discharge into the public sewer 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, and any wastes which have a flashpoint lower than 187° F. (86° C.).
B. 
Toxic substances. Any toxic substances in amounts exceeding standards promulgated by the Administrator of the United States Environmental Protection Agency pursuant to the Act (now Section 307[a]) and chemical elements or compounds, phenols or other taste- or odor-producing substances, or any other substances which singly or by interaction with other wastes are not susceptible to treatment or which may interfere with the biological processes or efficiency of the wastewater treatment system, or that will pass through the system without being treated to the required degree.
C. 
Corrosive wastes. Any waste which will cause corrosion or deterioration of the wastewater treatment system. All wastes discharged to the public sewer system must have a pH value in the range of 6 to 9 standard units. Prohibited materials include, but are not limited to, acids, sulfides, concentrated chloride and fluoride compounds and substances which will react with water to form acidic products.
D. 
Solid or viscous wastes. Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the wastewater treatment system, such as, but not limited to, ice, snow, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, lint, feathers, tar, plastics, wood, slurries, whole blood, hair and fleshings or hides, animal guts or tissues, entrails, bones, wax, paraffin, paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders, food processing bulk solids, spent lime, stone or marble dust, grass clippings, spent grains, grain processing wastes, spent hops, beer and distillery slops, wastepaper, acetylene generation sludge, asphalt residues, residues from refining or processing of fuel or lubricating oil, chemical residues, acid residues, and similar substances. This prohibition includes any wastewater which by interaction with other waters or wastes in the public wastewater treatment system forms suspended solids which obstruct the flow in the sewer or create a condition that interferes with the proper operation of the wastewater treatment system.
E. 
Oil and grease. Any wastewater containing fats, wax, grease or oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32° F. and 150° F. (0° C. and 65° C.).
F. 
Excessive temperature.
(1) 
Wastewater causing the temperature in the Town public sewer to exceed 150° F. (65° C.); or
(2) 
Wastewater of such high temperature and in such amounts as to cause the influent to the treatment facilities to exceed 104° F. (40° C.).
G. 
Improperly shredded garbage. Garbage that has not been ground or comminuted to such a degree that all particles will be carried freely in suspension under flow conditions normally prevailing in the public sewers.
H. 
Noxious materials. Noxious or malodorous solids, liquids or gases, which either singly or by interaction with other wastes, are capable of creating a public nuisance or hazard to any form of life, or are or may be sufficient to prevent entry into a sewer for its maintenance and repair.
I. 
Radioactive wastes. Radioactive wastes or isotopes of such half-life or concentration that they do not comply with regulations or orders issued by the appropriate authority having control over their use and/or which will or may cause damage or hazards to the wastewater treatment system or personnel operating the system.
J. 
Excessive discharge rate. Quantities of wastewater flow, concentrations, or both, which constitute a slug as defined herein, and which causes a treatment process upset or loss of treatment efficiency or impairment of the hydraulic capacity or the sanitary sewer.
K. 
Discolored material. Wastes with color such as but not limited to, dye water or vegetable tanning solution that are not removable by the treatment process.
A. 
General limitations on incompatible pollutants. No person shall discharge or convey, or permit or allow to be discharged or conveyed to a public sanitary sewer any wastewater containing incompatible pollutants of such character or quantity that will:
(1) 
Violate pretreatment standards;
(2) 
Cause the wastewater treatment works to violate its SPDES permit requirements;
(3) 
Violate the provisions of this chapter or other applicable laws, rules or regulations; or
(4) 
Not be susceptible to treatment or interfere with the process or efficiency of the wastewater treatment system or contaminate the sludge affecting the chosen sludge disposal method.
B. 
Specific limitations on certain incompatible pollutants. The following are the maximum concentrations of pollutants allowable in wastewater discharges to the wastewater treatment system as established by DEC. This chapter includes by reference any future revisions or additions to this list as promulgated by DEC or EPA. Dilution of any wastewater discharge for the purpose of satisfying these requirements shall be considered a violation of this chapter.

C. 
Limitations on compatible pollutants. In cases where effluent characteristics of an industrial or commercial discharge exceed the permissible limits for the compatible pollutants listed below, the acceptability of such waste will be left to the engineering judgement of the Town, or any other federal, state or local agencies having jurisdiction. The primary judgement criteria for the determination of acceptability by the Town and responsible authorities will be whether the admission of such waste will cause the wastewater treatment system to violate its SPDES permit or other provisions of this chapter. If it is determined the wastewater is acceptable, permission to discharge said compatible pollutants may be granted under conditions stated by the Superintendent. However, the Town will require, in accordance with Article XI, the payment of an additional industrial operation and maintenance surcharge for the additional cost of operation and maintenance and a user charge for the additional capital construction costs to cover the cost of treating the excessive strength wastewater. This charge is in addition to any sewer charges for the nonexcessive waste discharge. "Excessive strength wastewater" is defined as:
(1) 
Concentrations of suspended solids which exceed 250 mg/l (such as, but not limited to, Fullers earth, lime slurries, and lime residues) or dissolved solids, such as, but not limited to, sodium chloride in concentrations greater than 10,000 mg/l and sodium sulfate in concentrations greater than 500 mg/l.
(2) 
Concentrations of BOD which exceed 250 mg/l.
(3) 
Chlorine demand requirements exceeding 9.0 mg/l.
(4) 
Concentrations of free ammonia which exceed 25 mg/l.
A. 
No person shall discharge or cause to be discharged to the Town wastewater treatment system, wastewaters containing substances subject to an applicable federal categorical pretreatment standard promulgated by EPA, in excess of the quantity prescribed in such applicable pretreatment standards except as otherwise provided in this section. The Superintendent shall notify the affected industrial users of the required schedule for obtaining compliance with the applicable pretreatment standards. However, new sources shall initially comply with the existing pretreatment standards. The allowance of a time period in order to achieve compliance with the pretreatment standards will in no case be interpreted to allow any industry to discharge wastes in the interim that interfere with the wastewater treatment plant complying with its existing SPDES permit or violate any provision of this chapter. Town review, control and monitoring of the pretreatment system will be in accordance with Article VI.
B. 
Upon application by an industrial user, the Superintendent may revise any limitations on substances specified in the applicable pretreatment standards to reflect removal of the substances by the wastewater treatment facility. The revised discharge limit for specified substances shall be derived in accordance with the Act and will not be granted until approved by the EPA, or DEC, or their designated approval authority.
C. 
Upon application by an industrial user, the Superintendent may adjust any limitation on substances specified in the applicable pretreatment standards to consider factors relating to such user which are fundamentally different from the factors considered by EPA during the development of the pretreatment standard. Requests for and determinations of a fundamentally different adjustment shall be in accordance with the Act and will not be granted until approved by the EPA, or DEC, or their designated approval authority.
D. 
The cost to the Town for all services necessary to implement this section shall be the responsibility of the directly affected industry. Work under Subsections B and C will not be carried out without prior agreement by the industrial user for payment of the estimated cost.
No commercial or private collector (hauler) of wastewater shall discharge to the Town wastewater system without the prior approval of the Town Board.
