Village of Blue Mounds, WI Use of Public Sewers and Regulations

Except as hereinafter provided, no person shall discharge or cause to be discharged any of the following described water or waters to any public sewer:

Any gasoline, benzene, naphtha, fuel oil, other flammable or explosive liquid, solid, or gas.

Any waters or wastes containing toxic or poisonous solids, liquids, or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any waste treatment process that constitutes a hazard to humans or animals, creates a public nuisance, or creates any hazard in or has an adverse effect on the waters receiving any discharge from the wastewater treatment facility.

Any waters or wastes having a pH lower than 5.5 or higher than 9.0, or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the wastewater collection or treatment facility.

Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in public sewers, or other interference with the proper operation of the wastewater collection and treatment facilities, including but not limited to ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, hair and fleshings, entrails, paper dishes, cups, milk containers, diapers, feminine protection products, contraceptive devices, etc., either whole or ground by garbage grinders.

The following described substances, materials, waters, or waste shall be limited in discharges to municipal sanitary sewage systems to concentrations or quantities that will not harm either the sanitary sewer or wastewater treatment process or equipment; will not have an adverse effect on the receiving stream; will not otherwise endanger lives, limb, or public property; and will not constitute a nuisance. The Village may set limitations lower than the limitations established in the regulations below if in its opinion such more severe limitations are necessary to meet the above objectives. In forming an opinion as to the acceptability, the Village will give consideration to such factors as the quantity of subject waste in relation to flows and velocities in the sewers, materials of construction of the sewers, the wastewater treatment process employed, capacity of the waste in wastewater treatment facility, degree of treatability of the waste in the wastewater treatment facility, and other pertinent factors. The following limitations or restrictions on materials or characteristics of waste or wastewater discharged to the sanitary sewer shall not be violated without approval of the Village:

(1)

Wastewater having a temperature higher than 150° F. (65° C.).

(2)

Wastewater containing more than 25 milligrams per liter of petroleum oil, nonbiodegradable cutting oils, or product of mineral oil origin.

(3)

Any water or waste that may contain more than 100 mg/l of fat, oil, or grease.

(4)

Any garbage that has not been properly shredded by a garbage grinder or disposal.

(5)

Any waters or wastes containing iron, chromium, copper, zinc, mercury, and similar objectionable or toxic substances to such degree that any material received in the composite wastewater at the wastewater treatment facility exceeds the limits established by federal, state, or local authorities or by the Village for such materials.

(6)

Any waters or wastes containing odor-producing substances exceeding limits that may be established by local authorities or by the Village.

(7)

Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by applicable state or federal regulation.

(8)

Quantities of flow, concentrations, or both that constitute a "slug" as defined herein.

(9)

Water or wastes containing substances that are not amenable to treatment or reduction by the wastewater treatment processes employed or that are amenable to treatment only to such degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.

(10)

Any water or wastes that, by interaction with other water or wastes in the public sanitary sewage system, release obnoxious gases, form suspended solids that interfere with the collection system, or create a condition deleterious to structures and treatment processes.

(11)

Materials that exert or cause:

(a)

Unusual BOD, chemical oxygen demand or in such quantities as to constitute a significant load on the wastewater treatment plant.

(b)

Unusual volume of flow or concentration of wastes constituting a "slug" as defined herein.

(c)

Unusual concentrations of inert suspended solids (including but not limited to Fuller's earth, lime slurries, and lime residues) or of dissolved solids (including but not limited to sodium sulfate).

(d)

Excessive discoloration (including, but not limited to, dye wastes and vegetable tanning solutions).

(12)

Incompatible pollutants in excess of the allowed limits as determined by federal, state, or local laws and regulations in reference to pretreatment standards developed by the Environmental Protection Agency, 40 CFR 403.

No wastewater, regardless or character, shall be discharged to the sewage system in such a manner as to interfere with the designed operation of the wastewater treatment facility or to cause the wastewater treatment facility to exceed the limits presented by the WPDES Permit No. WI-0031650-4.

It shall be unlawful to construct or maintain any privy, privy vault, septic tank, holding tank, cesspool, or other facility intended or used for the disposal of sewage or wastewater without permission of the Village.
