All users of the Town of Hague sewage system will comply with all standards and requirements of the Act and standards and requirements promulgated pursuant to the Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 U.S.C. 1251, et seq., including but not limited to 40 CFR Parts 406-471.
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 sewage system. These general prohibitions apply to all such users of a sewage system 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 sewage system:
(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 sewage system, or to the operation of the sewage system. At no time shall both of 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 of Hague, the state, or the EPA has determined to be a fire hazard, or hazard to the sewage system.
(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 one-half 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 or stone grinding or polishing wastes.
(3) 
Any wastewater having a pH less than 5.0 or greater than 10.0.
(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 of the sewage system, or to exceed the limitation set forth in a National Categorical Pretreatment Standard.
(a) 
A toxic pollutant shall include, but not be limited to, any pollutant identified pursuant to the National Categorical Pretreatment Standard.
(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 fats, waxes, grease, or oils which become visible solids when the wastes are cooled to 10° C. (50° F.); any petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin, in excess of 100 mg/l or in amounts that will cause interference or pass through.
(7) 
Any wastewater 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 sewage system treatment plant influent temperature to be greater than 40° C. (104° F.). The Wastewater Treatment Plant Operator reserves the right, in certain instances, to prohibit or limit the discharge of wastes whose maximum temperatures are 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 Wastewater Treatment Plant Operator, 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.
(13) 
Any wastewater with a closed cup flashpoint of less than 140° F. or 60° C. using the test methods specified in 40 CFR Part 261.21.
(14) 
Any pollutants which result in the presence of toxic gases, vapors or fumes within the wastewater treatment system in a quantity that may cause acute worker health and safety problems.
Limitations on wastewater strength or mass discharge contained in this chapter may be supplemented with more stringent limitations when, in the opinion of the Wastewater Treatment Plant Operator:
A. 
The limitations in this chapter are not sufficient to protect the sewage system;
B. 
The limitations in this chapter are not sufficient to enable the sewage system treatment plant to comply with applicable water quality standards or the effluent limitations specified in the sewage system's SPDES permit;
C. 
The sewage system sludge will be rendered unacceptable for disposal or reuse as the Town of Hague desires, as a result of discharge of wastewaters at the above prescribed concentration limitations;
D. 
Municipal employees or the public will be endangered; or
E. 
Air pollution and/or groundwater pollution will be caused.
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.
A. 
Grease interceptors shall be required for all establishments preparing or serving food as well as for all other users when, in the opinion of the Wastewater Treatment Plant Operator, such interceptors are necessary for the proper handling of wastewater containing excessive amounts of grease, flammable substances, sand, or other harmful substances. All interceptors shall be of type and capacity approved by the Wastewater Treatment Plant Operator and shall be so located to be easily accessible for cleaning and inspection.
B. 
Grease and oil interceptors shall be required for all automotive service and repair establishments.
C. 
Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the owner, at his expense and records shall be maintained by the property owner documenting these maintenance activities. The Wastewater Treatment Plant Operator shall have the authority to copy any record related to wastewater discharges to the sewage system.
