Any gasoline, benzene, naptha, fuel oil, or other flammable
or explosive liquid, solid or gas;
(2)
Any wastes containing toxic or poisonous solids, liquids

A.
Limitations related to treatment plant influent. Discharge
to the local system of the following described substances, materials, waters
or waste shall be limited to the following concentrations or quantities, provided
that such concentrations or quantities will not harm the local system, regional
system, wastewater treatment plant, wastewater treatment process or equipment;
will not have an adverse effect on the receiving stream; will not have an
adverse effect on the sludge management program; will not endanger persons
or property; will not cause air pollution or other detrimental environmental
effects; and will not constitute a nuisance:
(1)
Liquid having a temperature higher than 65° C. (149°
F.) or any wastewater having a temperature which will inhibit biological activity
in the wastewater treatment plant, thereby resulting in interference; notwithstanding
the foregoing, in no case shall wastewater be discharged having a temperature
that causes the influent to the wastewater treatment plant to exceed 40°
C. (104° F.), unless the Commission Engineer certifies that the wastewater
treatment plant is designed to accommodate such temperature;
(2)
Wax, grease, oil, plastic or any other substance that
solidifies or becomes discernibly viscous;
(3)
Radioactive wastes which, alone or with other wastes,
result in releases greater than those specified by current United States Bureau
of Standards handbooks, or which violate rules or regulations of any applicable
regulatory agency;
(4)
Wastewater containing more than 50 milligrams per liter
of petroleum oil, nonbiodegradable cutting oils, or products of mineral oil
origin;
(5)
Wastewater containing more than 300 mg/l of oil or grease
of animal or vegetable origin;
(6)
Wastewater which in concentration of any given constituent
or in quantity of flow exceeds for any period of duration longer than 15 minutes
more than five times the average twenty-four-hour concentration or flows during
normal operation;
(7)
Wastewater which contains in excess of any of the following
constituents in a twenty-four-hour flow proportionate sample made up of an
aggregate of the total discharge from all of the outfalls of the industrial
user:
|
1.0 mg/l aluminum
| |

(a)
The Village shall cooperate with the Commission Engineer
in changing the requirements established in this chapter above if necessary
to meet the objectives of this chapter or a condition of the Commission's
WPDES permit;
(b)
Samples shall be collected over the period of discharge
if the discharge is less than 24 hours in duration;
(8)
Industrial discharges exceeding applicable National Categorical
Pretreatment Standards or state standards;
(9)
Any substance with objectionable color not removed in
the treatment process, such as, but not limited to, dye wastes and vegetable

Any discharge prohibited or limited as determined by
the Commission to be necessary to meet the objectives of this chapter or the
conditions of its WPDES permit.
B.
Limitations related to treatment plant effluent.
(1)
Specific. No person shall discharge any wastewater to
the local system which, in combination with other discharges, results in either:
(2)
General. No person shall cause or permit a discharge
into the local system that would cause, or significantly contribute to, either
directly or indirectly, a violation of the conditions of the Commission's
WPDES permit and any modification or reissuance thereof.
C.
Limitations superseded. Upon promulgation of National
Categorical Pretreatment Standards for a particular industrial user subcategory,
the federal standards (if more stringent than the limitations imposed under
these regulations) shall immediately supersede the limitations imposed under
these regulations, and such industrial user shall comply with said federal
standards upon notification by the Commission of the applicable requirements
under 40 CFR 403.12, as may be amended from time to time.
Dilution of an industrial discharge for purposes of reducing the pollutant
characteristics or concentrations to below the limitations established in
this article, or below other applicable pretreatment standards, is prohibited.
Any person who accidentally discharges into the local system wastes
or wastewater prohibited under these regulations shall immediately report
such a discharge to the Village and the Commission. Such report shall describe
the location, time and volume of the discharge and the type of waste or wastewater
discharged. Within 15 days of such discharge, a detailed written statement
describing the cause of the discharge and the measures taken to prevent a
future occurrence shall be submitted to the Village and Commission. Such reporting
shall not relieve the person causing the accidental discharge from any penalties
imposed by this chapter or Commission Regulations. Where the Village or Commission
deems necessary, industrial users shall provide facilities to prevent accidental
discharges or spills of wastes or wastewaters prohibited under these regulations.
If any waters or wastes are discharged or are proposed to be discharged
to the local system in excess of those limitations enumerated herein, the
Village, following consultation with the Commission, shall:
Industrial users shall comply with the provisions of this chapter and
Commission Regulations, as may be amended from time to time, and any additional
conditions related to a specific industrial user as determined by the Village
and Commission. Industrial users may be required to pretreat their wastewater
when necessary to protect the wastewater facilities or prevent discharge of
incompatible pollutants. Construction, operation and maintenance of pretreatment
facilities shall be at the expense of the user. Pretreatment facilities shall
be operated by qualified personnel holding a Grade 1 certificate in appropriate
subgrade as issued by the DNR.
The Village shall require such traps as are deemed necessary by the
Commission, in its sole opinion, for the proper handling of liquid wastes
containing floatable oil or grease in amounts in excess of the limitations
as specified in this article, or any flammable wastes, sand, or other harmful
ingredients. However, such traps shall not be required for private living
quarters or dwelling units. All such traps shall be of a type and capacity
approved by the Commission and shall be located as to be readily and easily
accessible for cleaning and inspection. In maintaining these traps, the Village
or other owner shall be responsible for the proper removal and disposal by
appropriate means of the captured material and shall maintain records of the
dates and means of disposal. Such records shall be submitted to the Village
and Commission upon request. Disposal of the collected materials must be in
accordance with applicable DNR rules and regulations.
