this title (relating to Definitions).
(1) For an internal floating roof storage tank, the
internal floating roof and the primary seal or the secondary seal
(if one is in service) must be visually inspected through a fixed
roof inspection hatch at least once every 12 months.
(A) If the internal floating roof is not resting on
the surface of the volatile organic compounds (VOC) inside the storage
tank and is not resting on the leg supports; or liquid has accumulated
on the internal floating roof; or the seal is detached; or there are
holes or tears in the seal fabric; or there are visible gaps between
the seal and the wall of the storage tank, within 60 days of the inspection
the owner or operator shall repair the items or shall empty and degas
the storage tank in accordance with Subchapter F, Division 3 of this
chapter (relating to Degassing of Storage Tanks, Transport Vessels,
and Marine Vessels).
(B) If a failure cannot be repaired within 60 days
and if the storage tank cannot be emptied within 60 days, the owner
or operator may submit written requests for up to two extensions of
up to 30 additional days each to the appropriate regional office.
The owner or operator shall submit a copy to any local air pollution
control program with jurisdiction. Each request for an extension must
include a statement that alternate storage capacity is unavailable
and a schedule that will assure that the repairs will be completed
as soon as possible.
(2) For an external floating roof storage tank, the
secondary seal gap must be physically measured at least once every
12 months to insure compliance with §115.112(a)(2)(F), (d)(2)(F),
and (e)(2)(G) of this title (relating to Control Requirements).
(A) If the secondary seal gap exceeds the limitations
specified by §115.112(a)(2)(F), (d)(2)(F), and (e)(2)(G) of this
title, within 60 days of the inspection the owner or operator shall
repair the items or shall empty and degas the storage tank in accordance
with Subchapter F, Division 3 of this chapter.
(B) If a failure cannot be repaired within 60 days
and if the storage tank cannot be emptied within 60 days, the owner
or operator may submit written requests for up to two extensions of
up to 30 additional days each to the appropriate regional office.
The owner or operator shall submit a copy to any local air pollution
control program with jurisdiction. Each request for an extension must
include a statement that alternate storage capacity is unavailable
and a schedule that will assure that the repairs will be completed
as soon as possible.
(3) If the storage tank is equipped with a mechanical
shoe or liquid-mounted primary seal, compliance with §115.112(a)(2)(F),
(d)(2)(F), and (e)(2)(G) of this title can be determined by visual
inspection.
(4) For an external floating roof storage tank, the
secondary seal must be visually inspected at least once every six
months to ensure compliance with §115.112(a)(2)(E) and (F), (d)(2)(E)
and (F), and (e)(2)(F) and (G) of this title.
(A) If the external floating roof is not resting on
the surface of the VOC inside the storage tank and is not resting
on the leg supports; or liquid has accumulated on the external floating
roof; or the seal is detached; or there are holes or tears in the
seal fabric; or there are visible gaps between the seal and the wall
of the storage tank, within 60 days of the inspection the owner or
operator shall repair the items or shall empty and degas the storage
tank in accordance with Subchapter F, Division 3 of this chapter.
(B) If a failure cannot be repaired within 60 days
and if the storage tank cannot be emptied within 60 days, the owner
or operator may submit written requests for up to two extensions of
up to 30 additional days each to the appropriate regional office.
The owner or operator shall submit a copy to any local air pollution
control program with jurisdiction. Each request for an extension must
include a statement that alternate storage capacity is unavailable
and a schedule that will assure that the repairs will be completed
as soon as possible.
(5) For fixed roof storage tanks in the Bexar County,
Dallas-Fort Worth and Houston-Galveston-Brazoria areas, storing crude
oil or condensate prior to custody transfer or at a pipeline breakout
station for which the owner or operator is required by §115.112(e)
of this title to control flashed gases, the owner or operator shall
inspect and repair all closure devices not connected to a vapor recovery
unit or other vapor control device according to the schedule in this
paragraph.
(A) The owner or operator shall conduct an audio, visual,
and olfactory inspection of each closure device not connected to a
vapor recovery unit or other vapor control device to ensure compliance
with §115.112(e)(7)(A) of this title. The inspection must occur
when liquids are not being added to or unloaded from the tank. If
the owner or operator finds the closure device open for reasons not
allowed in §115.112(e)(7)(A) of this title, the owner or operator
shall attempt to close the device during the inspection. The inspection
must occur before the end of one business day after each opening of
a thief or access hatch for sampling or gauging, and before the end
of one business day after each unloading event. If multiple events
occur on a single day, a single inspection within one business day
after the last event is sufficient.
(B) The owner or operator shall conduct an audio, visual,
and olfactory inspection of all gaskets and vapor sealing surfaces
of each closure device not connected to a vapor recovery unit or other
vapor control device once per calendar quarter to ensure compliance
with §115.112(e)(7)(B) of this title. If the owner or operator
finds an improperly sealed closure device, the owner or operator shall
make a first attempt at repair no later than five calendar days after
the inspection and repair the device no later than 15 calendar days
after the inspection unless delay of repair is allowed. If parts are
unavailable, repair may be delayed. Parts must be ordered promptly
and the repair must be completed within five days of receipt of required
parts. Repair may be delayed until the next shutdown if the repair
of the component would require a shutdown that would create more emissions
than the repair would eliminate. Repair must be completed by the end
of the next shutdown. For the purpose of this subparagraph, a repair
is complete if the closure device no longer exudes process gasses
based on sight, smell, or sound.
(b) The following inspection requirements apply in
Gregg, Nueces, and Victoria Counties.
(1) For an internal floating roof storage tank, the
following inspection requirements apply.
(A) If during an inspection of an internal floating
roof storage tank, the internal floating roof is not resting on the

leg supports; or liquid has accumulated on the internal floating roof;
or the seal is detached; or there are holes or tears in the seal fabric;
or there are visible gaps between the seal and the wall of the storage
tank, within 60 days of the inspection the owner or operator shall
repair the items or shall empty and degas the storage tank.
(B) If a failure cannot be repaired within 60 days
and if the storage tank cannot be emptied within 60 days, the owner
or operator may submit written requests for up to two extensions of
up to 30 additional days each to the appropriate regional office.

control program with jurisdiction. Each request for an extension must
include a statement that alternate storage capacity is unavailable

and if the storage tank cannot be emptied within 60 days, the owner
or operator may submit written requests for up to two extensions of
up to 30 additional days each to the appropriate regional office.

control program with jurisdiction. Each request for an extension must
include a statement that alternate storage capacity is unavailable
and a schedule that will assure that the repairs will be completed
