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. 
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 fire or 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 point in the system) be more than 25% nor shall any single reading be more than 40% 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, carbides, hydrides and sulfides and any other substances which the Village of Oxford, the state or the EPA has determined to be a fire hazard or a 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. Such substances include, but are not limited to, grease, garbage with particles greater than one-half (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, waste paper, 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 of less than five point zero (5.0) or greater than ten point zero (10.0), unless the POTW is 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, 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 POTW or 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 hazard to life or are sufficient to prevent entry into the sewers for their maintenance and 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 miligram/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 not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions.
(9) 
Any solids, 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 Wastewater Treatment Operator reserves the right in certain instances, to prohibit wastes at temperatures lower than 65° C.[1]

Editor's Note: Amended at time of adoption of Code; see Ch. 1, General Provisions, Art. I.
(10) 
Unusual volume of flow or concentration of wastes, constituting sludges, except by industrial wastewater permit.
(11) 
Any wastewater containing any radioactive wastes except as approved by the Wastewater Treatment Operator and in compliance with applicable state and federal regulations.[2]
[2]
Editor's Note: Amended at time of adoption of Code; see Ch. 1, General Provisions, Art. I.
(12) 
Any wastewater which causes a hazard to human life or which creates a public nuisance, either by itself or in combination with other wastes.
A. 
No person shall discharge, directly or indirectly, into the POTW wastewater containing any of the following substances in concentrations exceeding those specified below on either a daily or instantaneous basis. Concentration limits are applicable to wastewater effluents at a point just prior to discharge into the Village of Oxford POTW (end of pipe concentrations).

NOTES:
1 Except for chromium (hex), all concentrations listed for metallic substances shall be "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 grab sample taken of 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.
C. 
Limitations on wastewater strength contained in this chapter may be supplemented with more stringent limitations when, in the opinion of the Wastewater Treatment Operator:[1]
(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 plant's POTW's SPDES permit.
(3) 
The POTW sludge will be rendered unacceptable for disposal or reuse as the Village of Oxford desires, as a result of discharge of wastewaters at the above-prescribed concentration limitations.
(4) 
Municipal employees or the public will be endangered.
(5) 
Air pollution and/or groundwater pollution will be caused.

Editor's Note: Amended at time of adoption of Code; see Ch. 1, General Provisions, Art. I.
D. 
The limitations on wastewater strength shall be recalculated not less frequently than once every five years. The results of these calculations shall be reported to the Village of Oxford Board. This chapter shall then be amended appropriately. Any issued industrial wastewater discharge permits which have limitations, based directly on any limitations, which were charged, shall be revised and amended, as appropriate.
The Village of Oxford Board may, from time to time, amend the limitations set forth in § 230-48, recognizing changing industrial flows, changed SPDES permit limitations, new sludge disposal options and based on the current knowledge of the effect of pollutant discharges.
Except where expressly authorized to do so by an applicable pretreatment standard, no sewer 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.
All users of the Village of Oxford POTW will comply with all standards and requirements of the Act and standards and requirements promulgated pursuant to the Act.
Grease, oil and sand interceptors shall be provided when, in the opinion of the Wastewater Treatment Operator, 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 type and capacity approved by the Wastewater Treatment Operator 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.
