C. Internal Floating Roof. An internal floating roof
consists of a pontoon type roof, double deck type roof, or
internal floating cover which will rest or float on the surface
of the liquid contents and is equipped with a closure seal to
close the space between the roof edge and tank wall. All tank
gauging and sampling devices shall be gas tight except when
gauging or sampling is taking place. If the organic
compounds have a vapor pressure of 11.0 psia or greater
under actual storage conditions, the requirements of
Subsection F of this Section shall supersede the requirements
of this Subsection. In the parishes of Ascension, Calcasieu,
East Baton Rouge, Iberville, Livingston, Pointe Coupee, and
West Baton Rouge, the following additional requirements
apply:
1. The closure seal shall consist of either:
a. a liquid mounted seal consisting of a foam- or
liquid-filled seal mounted in contact with the liquid between
the wall of the storage vessel and the floating roof
continuously around the circumference of the tank;
b. a mechanical shoe seal (metallic-type shoe seal)
consisting of a metal sheet held vertically against the wall of
the storage vessel by springs or weighted levers and connected
by braces to the floating roof. A flexible coated fabric
(envelope) spans the annular space between the metal sheet
and the floating roof; or
c. two seals mounted one above the other so that each
forms a continuous closure that completely covers the space
between the wall of the storage vessel and the edge of the
internal floating roof. The lower seal may be vapor-mounted,
but both must be continuous.
2. Each opening in the internal floating roof (except rim
space vents and automatic bleeder vents) shall be provided
with a projection below the liquid surface. In addition, each
opening (except for leg sleeves, bleeder vents, rim space
vents, column wells, ladder wells, sample wells, and stub
drains) shall be provided with a cover equipped with a gasket.
Automatic bleeder vents and rim space vents shall be gasketed
and ladder wells shall be equipped with a sliding cover.
3. If the internal floating roof does not meet the
specifications of this rule, then the specifications shall be met
at the earlier of either the next scheduled maintenance
turnaround (when deinventorying and degassing occurs) or
December 1, 2005. Any request for an extension beyond
December 1, 2005, shall be examined on a case-by-case basis
and must be approved by the administrative authority*.

D. External Floating Roof. An external floating roof
consist of a pontoon type roof, double deck type roof, or
external floating cover which will rest or float on the surface
of the liquid contents and is equipped with a primary closure
seal to close the space between the roof edge and tank wall
and a continuous secondary seal (a rim mounted secondary)
extending from the floating roof to the tank wall. In the
parishes of Ascension, Calcasieu, East Baton Rouge, Iberville,
Livingston, Pointe Coupee, and West Baton Rouge, the
primary closure seal shall consist of a liquid mounted seal or
a mechanical shoe seal, as defined in Subsection C.1.a and b
of this Section. Installation of the primary and secondary
seals in these parishes shall be within the same time
requirements as stipulated in Subsection C.3 of this Section.

which also has a secondary seal from the top of the shoe seal
to the tank wall (i.e., a shoe-mounted secondary).
d. an alternate seal or seals can be used in lieu of the primary and secondary seals required herein provided the resulting emission is not greater than that which would have resulted if the primary and secondary seals were installed. The equivalency demonstration will be made to the satisfaction of the administrative authority*.
2. The seal closure devices required in LAC 33:III.2103.D shall:
a. have no visible holes, tears, or other openings in the seal(s) or seal(s) fabric.
b. be intact and uniformly in place around the circumference of the floating roof and the tank wall.

The primary seal gap measurements shall be made every five years at any tank level provided the roof is off its legs. Conditions not up to standards described in LAC 33:III.2103.D.2 shall be recorded along with date(s) that the standards are not met and the administrative authority shall be notified within seven days. To avoid noncompliance with this Section, repairs necessary to be in compliance must be initiated within seven working days of recognition of defective conditions by ordering appropriate parts. Repairs shall be completed within three months of the ordering of the repair parts. However, if it can be demonstrated that additional time for repair is needed, the administrative authority may extend this deadline.

the external floating roof, except for automatic bleeder vents,
rim space vent, and leg sleeves, are to provide a projection
below the liquid surface. Except for automatic bleeder vents,
rim space vents, roof drains, and leg sleeves, each opening in
the roof is to be equipped with a cover, seal, or lid that is to be
maintained in a closed position at all times (i.e., no visible
gap) except when the device is in actual use. Automatic
