All users within the Gananda Sewer District will comply with all standards and requirements of the Act and standards and requirements promulgated pursuant to the Act.
A. 
No user shall contribute or cause to be contributed, in any manner or fashion, 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 a POTW, whether or not the user is subject to National Categorical Pretreatment Standards, or any other national, state, or local pretreatment standards or requirements.
B. 
Without limiting the generality of the foregoing, a user may not contribute the following substances to the POTW:
(1) 
Any solids, liquids 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 a fire or an explosion or be injurious in any way to the POTW or to the operation of the POTW. At no time shall two successive readings on a flame-type explosion hazard meter at the point of discharge into the system (or at any other point in the system) be more than 25% nor any single reading be more than 40% of the lower explosive limit (LEL) of the meter. Unless explicitly allowable by a written permit, prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, carbides, hydrides and sulfides and any other substance which the Town, the state or the EPA has determined to be a fire hazard or hazard to the POTW.
(2) 
Solid or viscous substances which may cause obstruction to the flow in a sewer or otherwise interfere with the operation of the wastewater treatment facilities. Unless explicitly allowable by a written permit, such substances include, but are 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 fuel or lubricating oil, mud, or glass grinding or polishing wastes.
(3) 
Any wastewater having a pH less than 5.0 or greater than 10.0, unless the POTW was specifically designed to manage such wastewater, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment and/or POTW personnel.
(4) 
Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants (including heat), to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters or 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 Section 307(A) of the Act.
(5) 
Any noxious or malodorous solids, liquids or gases which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or a hazard to life or are sufficient to prevent entry into the sewers for their maintenance or repair.
(6) 
Oils and grease; any commercial, institutional or industrial wastes containing floatable fats, waxes, grease or oils or which become floatable when the wastes cool to the temperature prevailing in the wastewater at the POTW treatment plant during the winter season; also any commercial, institutional or industrial wastes containing more than 100 milligrams per liter of emulsified oil or grease; also any substances which will cause the sewage to become substantially more viscous, at any seasonal sewage temperature in the POTW.
(7) 
Any substance which will cause interference or pass-through.
(8) 
Any wastewater with objectionable color which is not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions.
(9) 
Any solid, liquid, vapor or gas having a temperature higher than 65° C. (150° F.); however, such materials shall not cause the POTW treatment plant influent temperature to be greater than 40° C. (104° F.). The Superintendent reserves the right, in certain instances, to prohibit wastes at temperatures lower than 65° C.
(10) 
Unusual flow rate or concentration of wastes, constituting slugs, except by industrial wastewater permit.
(11) 
Any wastewater containing any radioactive wastes, except as approved by the Superintendent and in compliance with applicable state and federal regulations.
(12) 
Any wastewater which causes a hazard to human life or which creates a public nuisance, either by itself or in combination, in any way, with other wastes.
A. 
No person shall discharge, directly or indirectly, into the sewer system of the Gananda Sewer district wastewater containing any of the following substances in concentrations exceeding those specified below on either a daily or an instantaneous basis, except by permit or as provided for herein. Concentration limits are applicable to wastewater effluents at a point just prior to discharge into the POTW (end-of-pipe concentrations).

NOTES:
(1)
Except for chromium (hex), all concentrations listed for metallic substances shall be as "total metal," which shall be defined as the value measured in a sample acidified to a pH value of two or less, without prior filtration.
(2)
As determined on a composite sample taken from the user's daily discharge over a typical operational and/or production day.
(3)
As determined on a grab sample taken from the user's discharge at any time during the daily operational and/or production period.
B. 
Other substances which may be limited are:
(1) 
Antibiotics.
(2) 
Chemical compounds which, upon acidification, alkalinization, oxidation or reduction, in the discharge or after admixture with wastewater and its components in the POTW produce toxic, flammable or explosive compounds.
(3) 
Pesticides, including algicides, fungicides, herbicides, insecticides and rodenticides.
(4) 
Polyaromatic hydrocarbons.
(5) 
Viable pathogenic organisms from industrial processes or hospital procedures.

B. 
Considerations.
(1) 
To ensure that none of the above noted limitations are violated, the Superintendent shall issue permits to significant industrial users limiting the discharge of the substances noted above. Each permit shall restrict the discharge from each significant industrial user to a portion of the total allowable influent loading. In determining what portion of the total of each substance that each significant industrial user shall be allowed to discharge, the superintendent shall consider:
(a) 
The quantities of each substance that are uncontrollable because they occur naturally in wastewater.
(b) 
The quantities of each substance that are anthropogenic but are nonetheless uncontrollable.
(c) 
Historical discharge trends.
(d) 
Past pollution control efforts of each significant industrial user as compared to other significant industrial dischargers of the same substance.
(e) 
Potential for growth in the POTW service area.
(f) 
Potential for more restrictive regulatory requirements to be placed on the POTW discharge or sludge disposal or sludge reuse method.
(g) 
Treatability of the substance.
(2) 
The Superintendent shall apply a 15% safety factor protective of the POTW.
C. 
All samples of influent loads to the POTW must be tested by a laboratory certified by the New York State Department of Health.
D. 
Permits issued in accordance with this section may allow for discharges in excess of limitations set forth under § 235-78.
A. 
Limitations on wastewater strength or mass discharge contained in this chapter may be supplemented with more stringent limitations when, in the opinion of the Superintendent:
[Amended 3-28-1996 by L.L. No. 2-1996]
(1) 
The limitations in this chapter are not sufficient to protect the POTW;
(2) 
The limitations in this chapter are not sufficient to enable the POTW treatment plant to comply with applicable water quality standards or the effluent limitations specified in the POTW's State Pollutant Discharge Elimination System (SPDES) permit;
(3) 
The POTW sludge will be rendered unacceptable for disposal or reuse as the Town of Walworth desires, as a result of discharge of wastewaters at the above prescribed concentration limitations;
(4) 
Municipal employees or the public will be endangered; or
(5) 
Air pollution and/or groundwater pollution will be caused.
B. 
The limitations on wastewater strength or mass discharge shall be recalculated not less frequently than once every five years. The results of these calculations shall be reported to the Town Board. This chapter shall then be amended appropriately. Any issued industrial wastewater discharge permits which have limitations based directly on any limitations which were changed shall be revised and amended as appropriate.
A. 
Except where expressly authorized to do so by an applicable pretreatment standard, 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 a pretreatment standard.
B. 
Dilution flow shall be considered to be inflow.
Grease, oil, and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of wastewater containing excessive amounts of grease, flammable substances, sand or other harmful substances, except that such interceptors shall not be required for private living quarters or living units. All interceptors shall be of a type and capacity approved by the Superintendent and shall be so located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned and repaired regularly as needed, by the owner, at his expense.
