waters or wastes to the sewer system:
(1) Any gasoline, benzene, naphtha, fuel oil, lubricating oil, or other flammable or
explosive liquid, solid, or gas.
(2) Any waters 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, constitute a hazard to humans or animals, or create a
public nuisance.
(3) Any waters or wastes having a pH lower than 5.5., or having any other corrosive
property capable of causing damage or hazard to structures, equipment, and
personnel.
(4) Solid or viscous substances in quantities or of such size capable of causing
obstruction to the flow in sewers or other interference with the proper operation of
the sewer system and wastewater treatment works such as but not limited to ashes,
bones, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics,
wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails,
and paper dishes, cups, milk containers, etc., either whole or ground by garbage

(d) The following described substances, materials, waters, or waste shall be limited in
discharges to the sewer system to concentrations or quantities which will not harm either the
sewer system, waste water treatment works processes, or equipment, will not have an
adverse effect on the underlying groundwater, or will not otherwise endanger lives, limb,
public property, or constitute a nuisance. The board may set limitations lower than the
limitations established in the regulations below if, in the opinion of the board, such more
severe limitations are necessary to meet the above objectives. In forming an opinion as to
the acceptability, the board will give consideration to such factors as the quantity of subject
waste in relations to flows and velocities in the sewers, materials or construction of the
sewers, the wastewater treatment process employed, capacity of the wastewater treatment
works, degree of treatability of the waste in the wastewater treatment works, and other
pertinent factors. The limitations or restrictions on materials or characteristics of waste or
wastewaters discharged to the sewer system which shall not be violated without approval of
the board are as follows:
(1) Wasterwater having a temperature higher than 150 degrees Fahrenheit (65
degrees Celsius).
(2) Wastewater containing petroleum oil, nonbiodegradable cutting oils, or products
of mineral oil origin exceeding limits which may be established by the board.

(4) Any garbage that has not been properly shredded (see section 6-7-2(n)). Garbage
grinders may be connected to sanitary sewers from homes, hotels, institutions,
restaurants, hospitals, catering establishments, or similar places where garbage
originates from the preparation of food in kitchens for the purpose of consumption on
the premises or when served by caterers.
(5) Any waters or wastes containing iron, chromium, copper, zinc, and similar
objectionable or toxic substances to such degree that any such material received in
the composite wastewater at the wastewater treatment works exceeds the limits
established by the board for such materials.
(6) Any waters or wastes containing odor-producing substances exceeding limits
which may be established by the board.
(7) Any radioactive wastes or isotopes of such half-life concentration as may exceed
limits established by the board.
(8) Quantities of flow, concentrations, or both which constitute a "slug" as defined
herein.
(9) Waters or wastes containing substances which are not amenable to treatment or
reduction by the wastewater treatment works, or are amenable to treatment only to
such degree that the effluent from the wastewater treatment works may degrade the
quality of the underlying groundwater.
(10) Any water or wastes which, by integration with other water or wastes in the
sewer system, may release obnoxious gases, form suspended solids which interfere
with the collection system, or create a condition deleterious to structures and
treatment processes.
(e) If any waters or wastes are discharged or are proposed to be discharged to the sewer
system, which waters contain the substances or possess the characteristics enumerated in
section 6-7-5(d) and which in the judgment of the board may have a deleterious effect upon
the sewer system, wastewater treatment works, processes, equipment, or underlying
groundwater, or which otherwise create a hazard to life or constitute a public nuisance, the
Board may:
(1) Reject the wastes;
(2) Require pretreatment to an acceptable condition for discharge to the sewer
system;
(3) Require control over the quantities and rates of discharge.
If the board permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the board.
(f) Grease, oil, and sand interceptors shall be provided when, in the opinion of the board,
such devices are necessary for the proper handling of liquid wastes containing floatable
grease in excessive amounts, as specified in section 6-7-5(d)(3), or any flammable wastes,
sand, or other harmful ingredients, except that such interceptors shall not be required for
private living quarters or dwelling units. All interceptors shall be of a type and capacity
approved by the board and shall be located as to be readily and easily accessible for cleaning
and inspections. In the maintaining of the interceptors, the owner(s) 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. Any removal and hauling of the
collected materials not performed by owner(s)' personnel shall be performed by currently
licensed waste disposal firms.
(g) Where pretreatment or flow equalizing facilities are provided or required for any waters
or wastes, they shall be maintained continuously in satisfactory and effective operation by
the owner(s) at his expense.
(h) All measurements, tests, and analyses of the characteristics of waters and wastes to
which reference is made in the Chapter shall be determined in accordance with the latest
edition of "Standard Methods for the Examination of Water and Wastewater," published by
the American Public Health Association. Sampling methods, location, times, durations, and
frequencies are to be determined on an individual basis subject to approval by the board.
