are primarily installed to receive wastewaters directly from facilities
which convey wastewater from individual structures or from private
property, and which include service connection "Y" fittings designed
for connection with those facilities. The facilities which convey
wastewater from individual structures, from private property to the
public sanitary sewer, or its equivalent, are specifically excluded
from the definition of "sewer system."

[Amended 2-25-2008 by Ord. No. 1935]
A. General discharge prohibitions. No discharger shall
contribute or cause to be discharged, directly or indirectly, any
of the following described substances into the wastewater disposal
system or otherwise to the facilities of the Village:
(1) Any liquids, solids or gases which by reason of their
nature or quantity are, or may be, sufficient either alone or by interaction
to cause fire or explosion or be injurious in any other way to the
operation of the Village wastewater facilities or the Milwaukee Metropolitan
Sewerage District (MMSD) wastewater treatment works.
(2) Solid or viscous substances which will or may cause
obstruction to the flow in a sewer or other interference with the
operation of the wastewater system.
(3) Any wastewater having a pH less than 5.0 or higher
than 10 or having any other corrosive property capable of causing
damage or hazard to structures, equipment, or personnel of the system.
(4) Any wastewater containing toxic pollutants in sufficient
quantity, either singly or by interaction, to injure or interfere
with any wastewater treatment process, to constitute a hazard to humans
or animals, or to exceed the limitation set forth in state or federal
categorical pretreatment standards. A toxic pollutant shall include
but not be limited to any pollutant identified in the Toxic Pollutant
List set forth in Ch. NR 215, Wis. Adm. Code.
(5) Any noxious or malodorous liquids, gases, or solids
which either singly or by interaction are capable of creating a public
nuisance or hazard to life or are sufficient to prevent entry into
the sewers for their maintenance and repair.
(6) Any substance which may cause the Village's and/or
MMSD's effluent or treatment residues, sludges, or scums to be unsuitable
for reclamation and reuse or to interfere with the reclamation process.
(7) Any substance which will cause the Village and/or
MMSD to violate its WPDES and/or other disposal system permits.
(8) Any substance with objectionable color not removed
in the treatment process, such as, but not limited to, dye wastes
and vegetable tanning solutions.
(9) Any wastewater having a temperature which will inhibit
biological activity in the MMSD wastewater treatment works resulting
in interference, but in no case wastewater with a temperature at the
introduction into the publicly owned treatment works which exceeds
40° C (104° F).
(10)
Any slug load, which shall mean any pollutant,
including oxygen demanding pollutants (BOD, etc.), released in a single
extraordinary discharge episode of such volume or strength as to cause
interference to the publicly owned treatment works.
(11)
Any unpolluted water, including but not limited
to noncontact cooling water.
(12)
Any wastewater containing any radioactive wastes
or isotopes of such half-life or concentration as exceeds limits established
by the approving authority in compliance with applicable state or
federal regulations.
(13)
Any wastewater which causes a hazard to human
life or creates a public nuisance.
(14)
Any stormwater, surface water, groundwater,
roof runoff or surface drainage or any other connections from inflow
sources to the sanitary sewer. Such waters may be discharged to a
storm sewer or other waterway with permission of the Village.
(15)
Any discharge into the sanitary sewerage system
that is in violation of the MMSD's ordinances and WPDES permit and
the modifications thereof.
B. Limitations on wastewater strength.
(1) National categorical pretreatment standards. National
categorical pretreatment standards as promulgated by the Unites States
Environmental Protection Agency shall be met by all dischargers of
the regulated industrial categories.
(2) State requirements. State requirements and limitations
on discharges to the publicly owned treatment works shall be met by
all dischargers which are subject to such standards in any instance
in which they are more stringent than federal requirements and limitations
or those in this article or any other applicable ordinance.
(3) Milwaukee Metropolitan Sewerage District (MMSD) requirements.
MMSD requirements and limitations on discharges to MMSD's publicly
owned treatment works shall be met by all dischargers.
(4) Right of revision. The approving authority reserves
the right to amend this article to provide for more stringent limitations
or requirements on discharges to the publicly owned treatment works
where deemed necessary to comply with the objectives set forth in
this article.
(5) Dilution. No discharger shall increase the use of
potable or process water in any way nor mix separate waste streams
for the purpose of diluting a discharge as a partial or complete substitute
for adequate treatment to achieve compliance with the standards set
forth in this article.
(6) Supplementary limitations.
(a)
No discharger shall discharge wastewater containing
concentrations (and/or mass limitations) above MMSD standards.
(b)
The approving authority may impose mass limitations
on dischargers which are using dilution to meet the pretreatment standards
or requirements of this article or in other cases where the imposition
of mass limitations is deemed appropriate by the approving authority.
(7) Accidental discharges.
(a)
Each discharger shall provide protection from
accidental discharge of prohibited or regulated materials or substances
established by this article. Where necessary, facilities to prevent
accidental discharge of prohibited materials shall be provided and
maintained at the discharger's cost and expense. Detailed plans showing
facilities and operating procedures to provide this protection shall
be submitted to the approving authority for review and shall be approved
by the approving authority before construction of the facility. Review
and approval of such plans and operating procedures by the approving
authority shall not relieve the discharger from the responsibility
to modify its facility as necessary to meet the requirements of this
article.
(b)
Dischargers shall notify the approving authority
immediately upon the occurrence of a slug load or accidental discharge
of substances prohibited by this article. The notification shall include
location of discharge, date and time thereof, type of waste, concentration
and volume, and corrective actions. Any discharger which discharges
a slug load of prohibited materials shall be liable for any expense,
loss or damage to the Village's wastewater facilities or the Milwaukee
Metropolitan Sewerage District's wastewater treatment works, in addition
to the amount of any fines imposed on the approving authority on account
thereof under state or federal law.
(c)
Signs shall be permanently posted in conspicuous
places on the discharger's premises advising employees whom to call
in the event of a slug or accidental discharge. Employers shall instruct
all employees who may cause or discover such a discharge with respect
to the emergency notification procedure.
