Transportation of Class I or II liquids from storage rooms in
buildings shall be in approved containers not in exceeding of
60 gallons (227 L) capacity. The handling or use of Class I or
II liquids in open containers is prohibited.
Exception: The above restrictions shall not apply to locations
conforming to Group H-1 and H-2 occupancy
requirements.
The Chief may impose reductions
or prohibitions on the amounts of flammable or combustible
liquids in storage or use when he finds that an
unusual risk is involved by reason of undue hazards to life, a
hazardous storage or operation, unusual exposure, or multiple
occupancies.
For every building or
portion of a building where flammable or combustible liquids
are used, processed, or stored in such a manner as to give rise
to undue hazard of fire or explosion from flammable liquids
or vapors, the Department may require that such areas be provided
with approved local exhaust ventilation or general
room ventilation, explosion venting, emergency drains,
curbs, warning systems, or approved fire extinguishing systems.
Where required by the fire code official, foam fire protection shall be provided for above-ground tanks, other than pressure tanks operating at or above 1 pound per square inch gauge (psig) (6.89 kPa) where such tank, or group of tanks spaced less than 50 feet (15 240 mm) apart measured shell to shell, has a liquid surface area in excess of 1,500 square feet (139 m2), and is in accordance with one of the following:
- Used for the storage of Class I or II liquids.
- Used for the storage of crude oil.
- Used for in-process products and is located within 100 feet (30 480 mm) of a fired still, heater, related fractioning or processing apparatus or similar device at a processing plant or petroleum refinery as herein defined.
- Considered by the fire code official as posing an unusual exposure hazard because of topographical conditions; nature of occupancy, proximity on the same or adjoining property, and height and character of liquids to be stored; degree of private fire protection to be provided; and facilities of the fire department to cope with flammable liquid fires.
The
maximum allowable size of containers, intermediate
bulk containers, and portable tanks shall be in accordance
with Table 5704.3.1.2.

The amount of
flammable or combustible liquids maintained for use in any
operating or processing area shall not exceed a supply sufficient
for one working day, unless a greater quantity is permitted
by special permit issued by the Department pursuant to
Section 105.8 of this article.
Safety cans shall be used for the
handling or temporary storage of Class I or II liquids in
any operating or processing area, unless otherwise
approved by the Department.
The center of
the oil well casing shall not be closer than 200 feet (60
960 mm) from every loading rack located on a bulk distributing
station.
Operating unit
shall be defined as: All of the contiguous lands lying
within any portion of the City in which drilling is permitted,
and which lands are included in the terms of the
lease, permit or other agreement pursuant to which the
well in question is drilled or authorized to be drilled,
whether such lands are in one ownership or in different
ownerships, and whether such lands are described in
said lease, permit or agreement as one parcel or as several
parcels. If there are separate units of noncontiguous
lands containing at least one net acre included in the
terms of such lease, permit, or agreement, each such
unit shall be deemed a separate Operating Unit.
Every Operating Unit
shall consist of at least one acre of contiguous land.
Parcels of land interrupted by a street shall not be
deemed to be contiguous. Where a parcel of land
consists of less than one net acre and is completely
surrounded by streets, and where all other provisions
of this article with reference to location of oil wells
can be complied with, such parcel of land may be
deemed an Operating Unit and one oil well permitted
thereon. Only one oil well shall be drilled for
each net acre in the Operating Unit.
Note: For the purposes of this section, an alley
shall not be included in the definition of "Street."
An approved legible
sign bearing the name of the oil well, the operator
thereof, and his emergency telephone number shall be
located and maintained on every oil well in a place
where it will be fully visible. There shall also be
located and maintained on every oil well a sign or plate
as may be required by the Chief, showing such registration
serial number as may be assigned to the oil well by
the Chief.
Oil well cellars shall be provided
and comply with Sections 5706.3.9.1 through
5706.3.9.4.
Oil well cellars shall be provided
and shall be constructed of noncombustible material.
When two or more oil wells
share a common cellar, such cellar shall be provided
with a fire protection system approved by the Chief.
Cellars shall be safeguarded by
noncombustible guardrails not less than 30 inches (760
mm) above grade or other adequate barrier approved by
the Chief.
No
person shall store or accumulate any dry weeds, grass, rubbish,
or other combustible materials or any waste, rubbish,
or junk whether combustible or not, within a radius of 50
feet (15 240 mm) from any oil well, derrick or tank, or any
building, machinery, or equipment used in the development,
production, or storage of petroleum. When any oil
well is placed on production, all combustible materials of
any kind, except those necessary for the production or
operation, shall be removed.
When an extraordinary
fire hazard exists in relation to the operation of any
oil well or its attendant equipment and appurtenances, all
operations incidental to the drilling for, production, treating,
or storage of Class I, II, and IIIA liquids shall cease
until it is safe to resume such operations. Under such conditions,
the Chief may require the removal of Class I, II,
and IIIA liquids which constitute such a hazard from any
tank or ground depression to a safe location.
At all times when
conducting drilling operations at an oil well, there shall be
available within 100 feet (30 480 mm) of such well not
less than two portable fire extinguishers, each having a
20B:C classification in accordance with Section 906 of
this article.
No person owning or having
possession or control of any oil well within the City shall
maintain or allow to exist thereon any moving parts or
machinery-in-use or intended to be used at such oil well,
unless such machinery or moving parts are securely
enclosed by an adequate noncombustible ventilated type
security fence, screen, or housing sufficient to prevent the
entry of unauthorized persons. Such security fence or
screen shall be not less than 5 feet (1525 mm) high, and if
equipped with gates, such gates must not be less than 5
feet (1525 mm) high and equipped with adequate hardware
to prevent the entry of unauthorized persons. A single
adequate security fence, screen, or housing may be
used to enclose more than one oil well. Security fences,
screens, or housings required by this subsection shall be
approved by the Chief.
Exception: This subsection shall not apply if a competent
person is in constant attendance, 24 hours a day, at
each oil well.
Where wells are located in
an area accessible to vehicular traffic, in addition to a
security fence there shall be a collision barrier. The collision
barrier shall be constructed of posts spaced a maximum
of 4 feet (1220 mm) on center and shall be set in
concrete or in steel sleeves which are encased in concrete.
Such posts shall be at least 5 feet (1525 mm) in length,
with 2 feet (610 mm) below ground and shall not be less
than 4 inch (102 mm) diameter, Schedule 40 iron pipe
filled with concrete. Collision barriers shall be located outside
the security fence and shall not be less than 10 feet
(3050 mm) from the center of the oil well casing.
Exception: The Chief may approve the omission of all
or part of both the security fence and collision barrier
when, by such omission, the well head and appurtenances
will not be exposed to damage from moving
vehicles, other heavy objects, or will not be accessible
to any unauthorized persons. The terms of any such
approval shall be in writing and shall become a condition
of the permit authorizing the installation, maintenance,
and use of such well head and appurtenances.
Every
oil well which has not been operated or which has ceased
to produce petroleum or natural gas for a continuous
period of 90 days shall be safeguarded in compliance with
the provisions of Sections 5706.3.15.1 through
5706.3.15.3.
All storage of material, whether
combustible or not, shall be removed from the oil well
site. The provisions of this subsection shall not apply to
approved tanks, boilers, pumps, piping, valves, or other
equipment, machinery, and facilities which are connected
together in a fixed position and form the operating
equipment and arrangement for normal oil
production procedure.
Above-ground tanks, pipe line,
oil and gas separators, dehydrating plants, or pump suction
pits, and other appurtenant equipment shall be
freed of flammable vapors or otherwise rendered safe
by a qualified person.
