the receiving waters.
§ 50.066 PRETREATMENT, EQUALIZATION OF
WASTE FLOWS.
(A) If any waters or wastes are discharged, or
are proposed to be discharged, to the public
sewers, which waters contain the substances
or possess the characteristics enumerated in §

the Regional Sewer District may have a deleterious
effect upon the sewage works, processes,
equipment or receiving waters, or which otherwise
create a hazard to life or constitute a public
nuisance, the Director of the Regional Sewer
District may:
(1) Require new industries (or other large
users) or industries (or other large users) with
significant increases in discharges to submit
information on wastewater quantities and characteristics
and obtain prior approval for discharges.

any reason deemed appropriate by the
Regional Sewer District,
(3) Require pretreatment of such wastes to
within the limits of normal sewage as defined,
(4) Require control or flow equalization of
such wastes so as to avoid any “slug” loads or
excessive loads that may be harmful to the
treatment works, or
(5) Require payment of a surcharge on any
excessive flows or loadings discharged to the
treatment works to cover the additional costs of
having capacity for and treating such wastes.
(B) If the Director of the Regional Sewer
District permits the pretreatment or equalization
of waste flows, the design and installation
of the plant and equipment shall be subject to
the review and approval of the Director of the
Regional Sewer District and subject to the
requirements of all applicable codes, ordinances

TESTS AND ANALYSES.
(A) When required by the Director of the
Regional Sewer District, the owner of any property
services by a building sewer carrying
industrial wastes shall install a suitable control
manhole together with such necessary meters
and other appurtenances in the building sewer
to facilitate observation, sampling and safely
located, and shall be constructed in accordance
with plans approved by the Director of
the Regional Sewer District. The manhole shall
be installed by the owner at his or her expense
and shall be maintained so as to be safe and
accessible at all times. Agents of the Regional
Sewer District, the state water pollution control
agencies and the U.S. Environmental
Protection Agency shall be permitted to enter
all properties for the purpose of inspection,
observation, measurement, sampling and testing.
(B) All measurements, tests and analyses of
the characteristics of waters and wastes to
which reference is made in this Code shall be
determined in accordance with the latest edition
of “Standard Methods of the Examination
of Water and Wastewater,” published by the
American Public Health Association and shall
be determined at the control manhole provided,
or upon suitable samples taken at the control
manhole, except for applications for
NPDES permits and report thereof which shall
be conducted in accordance with rules and
regulations adopted by the USEPA (40 CFR
136). In the event that no special manhole has
been required, the control manhole shall be
considered to be the nearest downstream manhole
in the public sewer to the point at which
the building sewer is connected. Sampling
shall be carried out by customarily accepted
methods to reflect the effect of constituents
upon the sewage works and to determine the
existence of hazards to life, limb and property.
The particular analyses involved will determine
whether a 24 hour composite of all outfalls of a
premises is appropriate or whether a grab
sample or samples should be taken. Normally,
but not always, BOD and suspended solids
analyses are obtained from 24 hour composites
of all outfalls, whereas pH’s are determined
from periodic grab samples.
§ 50.069 INDUSTRIAL WASTES; SPECIAL
AGREEMENT.
No statement contained in this Code shall be
construed as preventing any special agreement
or arrangement between the Regional
Sewer District and any industrial concern
whereby an industrial waste of unusual
strength or character may be accepted by the
Regional Sewer District for treatment, subject
to payment therefore, by the industrial concern,
at such rates as are compatible with §§
50.100 et seq.
§ 50.070 DISCHARGE OF WATERS FROM AIR
CONDITIONERS, COOLING, CONDENSING
SYSTEMS OR SWIMMING POOLS.
Unpolluted water from air conditioners, cooling,
condensing systems or swimming pools
shall be discharged to a storm water, where it
is available, or to a combined sewer approved
by the Regional Sewer District. Where a storm
sewer is not available, discharge may be to a
natural outlet approved by the Regional Sewer
District and by the state. Where a storm sewer,
combined sewer or natural sewer is not available,
such unpolluted water may be discharged
to a sanitary sewer pending written approval
by the Regional Sewer District.
PRETREATMENT REQUIREMENTS

more stringent requirements established by
the Regional Sewer District and any subsequent
state or federal guidelines and rules and
regulations.
