[Ord. No. 687 §709, 11-1-1960]
A.
A flammable liquid storage tank may be located underground, outside
of or under a building, if such installation meets the requirements
of this Section. The tank shall be so located with respect to existing
building foundations and supports that the loads carried by the latter
cannot be transmitted to the tank. The distance from any part of a
tank storing Class III liquids to the nearest wall of any basement,
pit cellar or property line shall not be less than one (1) foot. The
distance from any part of a tank storing Class I or II liquids to
the nearest wall of any basement pit or cellar shall not be less than

to avoid undermining of foundations of existing structures. Underground
tanks shall be set on firm foundation and surrounded with soft earth
or sand well tamped in place. Tanks shall be covered with a minimum
of two (2) feet of earth, or shall be covered with not less than one
(1) foot of earth on top of which shall be placed a slab of reinforced
concrete not less than four (4) inches thick. When underground tanks
are or are likely to be subjected to traffic, they shall be protected
against damage from vehicles passing over them by at least three (3)
feet of earth cover, or eighteen (18) inches of well tamped earth,

settling, sliding or shifting, and shall be so installed that the
bottom pitches to a draw off or drain opening at a slope of not less
than one-fourth (1/4) inch per foot of length.
[Ord. No. 687 §712, 11-1-1960]
A.
Storage tanks for flammable liquids shall not be located where, because
of topography or nearness of streams, flammable liquids could drain
or be carried to sites having structures of high values, places of
habitation or public assembly unless such tanks are diked in a manner
to prevent such drainage. Compliance with the provisions for dikes
contained in the suggested code for the storage, handling and use
of flammable liquids (No. 30) published by the National Fire Protection
Association or other nationally recognized standard shall be deemed
as complying with this requirement.
B.
Where provision is made for draining rain water from diked areas,
such drains shall normally be kept closed and shall be so designed
that when in use, they will not permit flammable liquids to enter
natural water courses, public sewers, or public drains, if their presence
would constitute a hazard.

will not enter building openings or be trapped under eaves or other
obstructions and for Class I and Class II liquids shall discharge
upward or horizontally.
F.
Fill opening for tanks storing flammable liquids shall be not less
than five (5) feet from a any building door or cellar or basement
opening. Fill and discharge openings for buried tanks shall enter

shall be so installed so that oil or vapor will not be discharged
into any building. Glass gauges, the breaking of which would allow
the escape of liquid or vapor into a building shall not be used.
H.
Vents, relief devices, emergency reliefs, flame arresters, gauging
devices and devices for the withdrawal of flammable liquids from storage
tanks shall be in accordance with suggested code published by the
National Fire Protection Association (No. 30) or similarly nationally

and handling of flammable liquids shall be designed for the working
pressures and structural stresses for which they may be subjected.
B.
Piping systems shall be substantially supported and protected against
physical damage and excessive stresses arising from settlement, vibration,
expansion or contraction. Pipe systems shall contain a sufficient
number of valves to operate the system properly and to protect the
plant. Pipe systems in connection with pumps shall contain sufficient
number of valves to properly control the flow of liquid in normal
operation and also in the event of physical damage. Check valves shall
be provided for automatic protection against back flow from aboveground
tanks where such tanks are filled by centrifugal pumps.
C.
Each connection to an aboveground tank storing flammable liquids,
located below normal liquid level, shall be provided with an internal
or external control valve located as close as practicable to the shell
of the tank and in addition there shall be an extra valve in each
such connection installed on the inside of the tank which is operable
both manually and by an effective heat releasing devices which will
close to prevent the flow of liquid from the tank in case of fire,
except that such valves shall not be required on a bulk plant tank
equipped with a swing line, and on tanks where transfer of products
between tanks, in the event of fire, is practicable.
D.
Heating and other devices using oil burners shall be installed, maintained
and operated in accordance with nationally recognized safe practices.
Storage tanks, burners and accessories such as piping, vents, filling
connections and control devices complying with the National Fire Protection
Association Standard for the "installation of oil burning equipment"
or a similarly nationally recognized standard shall be deemed to comply
with this Section.
E.
Fill and discharge openings for buried tanks storing flammable liquids
where practicable, shall enter tanks only through the top and connections
shall be graded toward the tank.

of buildings and from buried tanks shall, except as noted herein,
be by an approved pump through continuous piping so as to avoid the
exposure of the liquid or its vapors. Gravity feed of a flammable
liquid inside of a building shall be limited to fuel oil from supply
tanks not to exceed two hundred seventy-five (275) gallons individual
capacity nor five hundred fifty (550) aggregate capacity. Flammable
liquids shall not be withdrawn from a tank which operates through
pressure within a storage tank, unless the tank has been approved
as a pressure vessel for the use to which it is subjected. In no case
shall air or gas pressure be used for the withdrawn of a flammable
liquid from a storage tank. Tanks operating at above atmospheric pressure
shall be designed and constructed in accordance with the Unfired Pressure
Vessel Code of the American Society of Mechanical Engineers or a similarly
national recognized code satisfactory to the Building Inspector.
B.

otherwise permitted by this Chapter, application outlining the quantity
required and the necessity therefor shall be filed with the Building
Inspector who may issue special permit therefor providing the conditions
of such use and safeguards therefor are in conformity with requirements
contained in the 1957 suggested Code of the National Fire Protection
