No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, cooling water or unpolluted industrial process waters to any sanitary sewer.
Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the Plumbing Inspector. Industrial cooling water or unpolluted process waters may be discharged, upon approval of the Plumbing Inspector, to a storm sewer or natural outlet.
No user shall discharge or cause to be discharged, either directly or indirectly, to any public sewers, any substance or wastewater which could interfere with the operation or performance of the POTW. These general prohibitions also apply to all nondomestic users of the Town's facilities, whether or not the user is subject to national pretreatment standards or any other federal, state or local pretreatment requirements. The following substances and wastewaters are specifically prohibited from discharge into the Town's facilities:
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 days' readings on an explosion hazard meter, at the point of discharge into the system (or at any point in the system), be more than 10% or any single reading be 20% or more 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, perclilorates, bromates, carbides, hydrides and sulfides and any other substances which the Town, the state, the EPA or any other appropriate enforcement agency 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, 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 water or wastes having any corrosive property capable of causing damage or hazard to structures, equipment of the sewer system or personnel employed in its operation.
D. 
Any water or wastes 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 sewage treatment plant effluent, 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 Section 307(a) of the Clean Water Act.
E. 
Any water or wastes containing any chemical or biological constituent or having physical characteristics which could cause interference with any POTW wastewater treatment process.
F. 
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 maintenance and repair.
G. 
Any garbage containing particles greater than 1/2 inch in any dimension. The installation and operation of any garbage grinder equipped with a motor of 3/4 horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Plumbing Inspector.
H. 
Materials which exert or cause discolorations such as, but not limited to, dye waters and vegetable tanning solution.
I. 
In no case shall a substance discharged to the Town's facilities cause the POTW treatment plant to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Clean Water Act and criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to federal, state or local laws and regulations.
J. 
Any substance which will cause the POTW treatment plant to violate its NPDES/SPDES permit or the receiving water quality standards.
K. 
Any substance or wastewater which causes a hazard to human life or creates a public nuisance.
No person shall discharge or cause to be discharged into the public sewerage system any substance or wastes which exceed the limits established below:
A. 
Any water or wastes having a pH lower than 5.0 or higher than 12.0.
B. 
Any liquid or vapor having a temperature higher than 150° F. (65° C.). If, in the opinion of the Town Engineer or other appropriate regulatory agency, lower temperatures of such wastes could harm either the sewers, sewage treatment process or equipment, have an adverse effect on the receiving stream, or could otherwise endanger life, health or property, or constitute a nuisance, the Town Engineer may prohibit such discharges.
C. 
Any water or waste containing substances which may precipitate solidity or become viscous at temperatures between 32° and 104° F. (0° and 40° C.).
D. 
Any radioactive wastes or isotopes of such half-life or concentrations as may exceed limits established by applicable federal, state or other public agencies having jurisdiction.
E. 
Any pollutants, including oxygen-demanding pollutants (BOD, etc.) released at a flow rate and/or pollutant concentration which a user knows or has reason to know will cause interference to the POTW. In no case shall a slug load have a flow rate or contain concentrations or qualities of pollutants that exceed for any time period longer than 15 minutes more than five times the average twenty-four-hour concentration, quantities or flow during normal operation.
F. 
Any water or wastes which contain concentrations of total oil and grease in excess of 100 mg/l.
G. 
Concentration limits.
(1) 
Any waters, sewage or wastes containing quantities of pollutants in concentrations (milligrams per liter) which exceed the following, and similar objectionable or toxic substances in such concentrations which, in the opinion of the Town of West Seneca, will be detrimental to the collection system or treatment process.

For facilities with multiple outfalls to the public sewers, the limits established above shall apply to each individual outfall.
As a condition of the industrial discharge permit, an industrial user may be required to pay an industrial discharge surcharge. The industrial discharge surcharge may be required from those industrial users whose contribution of compatible pollutants creates costs in excess of that normally created by a domestic user. This surcharge will cover the appropriate debt service, operation and maintenance costs needed to collect, treat and dispose of wastes from the industrial user. The actual charge and formula for a particular industrial user for this service will be determined by the Town Board and collected with the industrial user's annual taxes.
No industrial user shall ever increase the use of process water or in any other way attempt to dilute a discharge as a means for obtaining compliance with any prohibited or limited discharge requirement of this chapter or any federal or state pretreatment requirement.
As federal categorical pretreatment standards are promulgated, the federal standard, if more stringent than limitations imposed under this chapter, shall immediately supersede the limitations imposed under this chapter. The Town Engineer shall notify all affected users of the applicable reporting requirements under 40 CFR 402-13. If limitations and/or regulations established by the POTW receiving or treating sewage generated in the Town of West Seneca are more stringent than limitations imposed under this chapter, the more stringent limitations shall apply.
In the case of an accidental or slug discharge, it is the responsibility of the user to immediately telephone and notify the Town Engineer and the POTW treatment plant of the incident. The notification shall include location of discharge, type of waste, concentration and volume and corrective actions being taken. Within five days following an accidental or slug discharge, the user shall submit to the Town a written report describing the cause of discharge and the measures which will be taken by the user to prevent recurrence of the noncompliance. Compliance with this section of this chapter shall not relieve the user of other liability or expense for damage to the POTW's facilities or 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 article or other applicable law.
The Town Engineer, Town Code Enforcement Officer or one of their designees that are employees of the Town shall have the right to inspect and/or test any building sewer and building drain and appurtenances or private sewers that discharge wastewater directly or indirectly to the Town's wastewater conveyance system. This includes the authority to inspect basements for illegal connections, such as sump pumps or other prohibited connections as indicated in § 97-23 (Prohibited connections). In the case of basement inspection, the Town Engineer or Code Enforcement Officer shall give notice of no less than 12 hours nor more than 48 hours if requested by the owner. If it is found that such sewers or drains are used or maintained in such a way as to cause any discharge that violates this chapter, the Town Code Enforcement Officer will initiate enforcement actions in accordance with Article IX (Enforcement).
