the treatment process or in any other way constitute a detriment to
the sewerage system, including the sewers, the pumping facilities,
the wastewater treatment plant or the receiving waters.

(1)
Those wastewaters, including industrial wastes, which will be accepted
in the sewerage system of the Town of Indian Head.

system the following described substances, materials, waters or wastes
if, in the opinion of the Engineer, such wastes can harm either the
sewers, pumping facilities, wastewater treatment process or equipment
or have an adverse effect on the receiving stream or can otherwise
endanger life, public property, or limb or constitute a nuisance.
In forming his opinion as to the acceptability of these wastes, the
Engineer will give consideration to such factors as the quantities
of the subject wastes in relation to flows and velocities in the sewers,
the materials of construction of the sewers, the nature of the wastewater
treatment process, the capacity of the wastewater treatment plant

may be approved by the Engineer, are:
(1)
Any liquid or vapor having a temperature higher than 150° F.
(65° C.).
(2)
Any water or waste containing fats, wax, grease or oils, whether
emulsified or not, in excess of 100 milligrams per liter or 1/4 pound
per day or containing substances which may solidify or become viscous
at temperatures between 32° and 150° F. (0° and 65°
C.).

and operation of any garbage grinder or comminutor equipped with a
motor of 3/4 horsepower (0.76 horsepower metric) or greater shall
be subject to the review and approval of the Engineer.
(4)
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 wastewater at the treatment plant exceeds
the limits established by the Engineer for such materials.
(5)
Any radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the Engineer in compliance with
applicable state and federal regulations.
(6)

public sewer lower than 5.5 or higher than 9.5 or which would in any
way cause damage to sewer, structures, equipment or wastewater treatment
process.
(8)
All industrial wastes that will not pass a No. 20 mesh screen.
B.
If any waters or wastes are discharged or are proposed to be discharged to the public sewers and said waters contain the substances or possess the characteristics enumerated in Subsection A of this section and which are prohibited from discharge to the sewerage system because, in the judgment of the Engineer, they may have a deleterious effect upon the sewerage system, treatment process or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Town may:
(1)
Reject the waste discharge or not approve the request for treatment
of the proposed wastes, as the case may be; or
(2)
Request the owner to comply with the following requirements in order
to obtain the written approval of the Engineer and thereby be permitted
to discharge the particular wastewater to the public sewerage system:
(a)
Pretreat, at his expense, the wastewater to an acceptable condition
for discharge to the public sewers, as described herein, except that
he would be required to pay standard Town surcharge rates for handling
excess amounts of BOD and/or suspended solids. Plans, specifications
and any other pertinent information relating to proposed preliminary
treatment facilities shall be submitted for the approval of the Engineer
and of the State Department of Health and the State Department of
the Environment, and no construction of such facilities shall be commenced
until said approvals are obtained in writing.
(b)
Provide necessary and approved controls over the quantities
and rates of discharge.
C.
The Engineer may require any or all of the following as conditions
before approval of the discharge of the wastes to the sewer: preliminary
treatment, payment of the Town surcharge rate where applicable or
flow equalization.
(1)
If the Engineer permits discharge to the sewer after preliminary
treatment or equalization of wastes flows, the design and installation
of the requisite facilities and equipment shall be subject to the
joint review and approval of the Engineer, the State Department of
Health and the State Department of the Environment, subject to the
requirements of all applicable codes, ordinances and laws.
(2)
Where preliminary treatment or flow-equalizing facilities are provided
for any waters or wastes, they shall be maintained continuously in
satisfactory and effective operation by the owner at his expense.
(3)
As part of such preliminary treatment, the Engineer will require
grease removal and screening of industrial wastes, where applicable.
Facilities for said pretreatment will be subject to the approval of
the Engineer.
(4)
The
owner of a pretreatment facility shall properly dispose of collected
sludges and/or materials at his own expense.
[Added at time of adoption of Code (see Ch. 1, General Provisions,
Art. III)]
D.
Grease, oil and sand interceptors shall be provided when, in the
opinion of the Engineer, they are necessary for the proper handling
of liquid wastes containing grease in excessive amounts, any flammable
wastes, sand, shellfish particles or other harmful ingredients, except
that such interceptors shall not be required for private living quarters
or dwelling units. All interceptors shall be designed to reduce the
liquid waste velocity to a maximum of one foot per second and, unless
otherwise authorized by the Town Engineer, shall have a minimum depth
of two feet six inches, and the velocity shall be determined by the
peak hourly discharge. All interceptors shall be of a type and capacity
approved by the Engineer and shall be located as to be readily and
easily accessible for cleaning and inspection by the Town or the Engineer.
E.
When required by the Engineer, the owner of any property serviced
by a building sewer carrying industrial wastes shall install a suitable
control manhole, together with such approved meters and other appurtenances,
in the building sewer to facilitate observation, sampling and measurement
of the wastes. Such manhole, when required, shall be accessible and
safely located and shall be constructed in accordance with plans approved
by the Engineer. The manhole shall be installed by the owner at his
expense and shall be maintained by him so as to be safe and accessible
at all times.
F.
All measurements, tests and analyses of the characteristics of water
and wastes to which reference is made in this article 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 or the latest edition of Methods for Chemical Analysis
of Water and Wastes published by the Environmental Protection Agency
or by a method acceptable to the State Department of Health and shall
be determined at the control manhole provided or upon suitable samples
taken at said control manhole. Sampling shall be carried out by customarily
accepted methods to reflect the effect of constituents upon the sewerage
system and to determine the existing hazards to life, limb and property.
The particular analysis involved will determine whether twenty-four-hour
composites or grab samples should be taken; pH is to be determined
by periodic grab samples. When additional sampling and analysis beyond
the normal are requested by a wastewater contributor, he shall pay
the Town's cost for performing the same unless said samples show appreciable
difference from the previous sampling and analysis.
G.
When the wastewater treatment facilities have reached a point near
maximum loading as determined and approved by the state and/or the
Town Engineer, the Town shall prohibit increased industrial discharge,
either on the basis of flow or quantity of waste constituents, or
both.
The maximum allowable concentration of heavy metals or substances

A.
Any person found to be violating any provision of this article shall
be served by the Town with a written notice, stating the nature of
