Sec. 60.113b Testing and procedures.
The owner or operator of each storage vessel as specified in Sec.
60.112b(a) shall meet the requirements of paragraph (a), (b), or (c) of
this section. The applicable paragraph for a particular storage vessel
depends on the control equipment installed to meet the requirements of
Sec. 60.112b.
(a) After installing the control equipment required to meet Sec.
60.112b(a)(1) (permanently affixed roof and internal floating roof),
each owner or operator shall:
(1) Visually inspect the internal floating roof, the primary seal,
and the secondary seal (if one is in service), prior to filling the
storage vessel with VOL. If there are holes, tears, or other openings in
the primary seal, the secondary seal, or the seal fabric or defects in
the internal floating roof, or both, the owner or operator shall repair
the items before filling the storage vessel.
[[Page 364]]
(2) For Vessels equipped with a liquid-mounted or mechanical shoe
primary seal, visually inspect the internal floating roof and the
primary seal or the secondary seal (if one is in service) through
manholes and roof hatches on the fixed roof at least once every 12
months after initial fill. If the internal floating roof is not resting
on the surface of the VOL inside the storage vessel, or there is liquid
accumulated on the roof, or the seal is detached, or there are holes or
tears in the seal fabric, the owner or operator shall repair the items
or empty and remove the storage vessel from service within 45 days. If a
failure that is detected during inspections required in this paragraph
cannot be repaired within 45 days and if the vessel cannot be emptied
within 45 days, a 30-day extension may be requested from the
Administrator in the inspection report required in Sec. 60.115b(a)(3).
Such a request for an extension must document that alternate storage
capacity is unavailable and specify a schedule of actions the company
will take that will assure that the control equipment will be repaired
or the vessel will be emptied as soon as possible.
(3) For vessels equipped with a double-seal system as specified in
Sec. 60.112b(a)(1)(ii)(B):
(i) Visually inspect the vessel as specified in paragraph (a)(4) of
this section at least every 5 years; or
(ii) Visually inspect the vessel as specified in paragraph (a)(2) of
this section.
(4) Visually inspect the internal floating roof, the primary seal,
the secondary seal (if one is in service), gaskets, slotted membranes
and sleeve seals (if any) each time the storage vessel is emptied and
degassed. If the internal floating roof has defects, the primary seal
has holes, tears, or other openings in the seal or the seal fabric, or
the secondary seal has holes, tears, or other openings in the seal or
the seal fabric, or the gaskets no longer close off the liquid surfaces
from the atmosphere, or the slotted membrane has more than 10 percent
open area, the owner or operator shall repair the items as necessary so
that none of the conditions specified in this paragraph exist before
refilling the storage vessel with VOL. In no event shall inspections
conducted in accordance with this provision occur at intervals greater
than 10 years in the case of vessels conducting the annual visual
inspection as specified in paragraphs (a)(2) and (a)(3)(ii) of this
section and at intervals no greater than 5 years in the case of vessels
specified in paragraph (a)(3)(i) of this section.
(5) Notify the Administrator in writing at least 30 days prior to
the filling or refilling of each storage vessel for which an inspection
is required by paragraphs (a)(1) and (a)(4) of this section to afford
the Administrator the opportunity to have an observer present. If the
inspection required by paragraph (a)(4) of this section is not planned
and the owner or operator could not have known about the inspection 30
days in advance or refilling the tank, the owner or operator shall
notify the Administrator at least 7 days prior to the refilling of the
storage vessel. Notification shall be made by telephone immediately
followed by written documentation demonstrating why the inspection was
unplanned. Alternatively, this notification including the written
documentation may be made in writing and sent by express mail so that it
is received by the Administrator at least 7 days prior to the refilling.
(b) After installing the control equipment required to meet Sec.
60.112b(a)(2) (external floating roof), the owner or operator shall:
(1) Determine the gap areas and maximum gap widths, between the
primary seal and the wall of the storage vessel and between the
secondary seal and the wall of the storage vessel according to the
following frequency.
(i) Measurements of gaps between the tank wall and the primary seal
(seal gaps) shall be performed during the hydrostatic testing of the
vessel or within 60 days of the initial fill with VOL and at least once
every 5 years thereafter.
(ii) Measurements of gaps between the tank wall and the secondary
seal shall be performed within 60 days of the initial fill with VOL and
at least once per year thereafter.
(iii) If any source ceases to store VOL for a period of 1 year or
more, subsequent introduction of VOL into the
[[Page 365]]
vessel shall be considered an initial fill for the purposes of
paragraphs (b)(1)(i) and (b)(1)(ii) of this section.
(2) Determine gap widths and areas in the primary and secondary
seals individually by the following procedures:
(i) Measure seal gaps, if any, at one or more floating roof levels
when the roof is floating off the roof leg supports.
(ii) Measure seal gaps around the entire circumference of the tank
in each place where a 0.32-cm diameter uniform probe passes freely
(without forcing or binding against seal) between the seal and the wall
of the storage vessel and measure the circumferential distance of each
such location.
(iii) The total surface area of each gap described in paragraph
(b)(2)(ii) of this section shall be determined by using probes of
various widths to measure accurately the actual distance from the tank
wall to the seal and multiplying each such width by its respective
circumferential distance.
(3) Add the gap surface area of each gap location for the primary
seal and the secondary seal individually and divide the sum for each
seal by the nominal diameter of the tank and compare each ratio to the
respective standards in paragraph (b)(4) of this section.
(4) Make necessary repairs or empty the storage vessel within 45
days of identification in any inspection for seals not meeting the
requirements listed in (b)(4) (i) and (ii) of this section:
(i) The accumulated area of gaps between the tank wall and the
mechanical shoe or liquid-mounted primary seal shall not exceed 212
Cm\2\ per meter of tank diameter, and the width of any portion of any
gap shall not exceed 3.81 cm.
(A) One end of the mechanical shoe is to extend into the stored
liquid, and the other end is to extend a minimum vertical distance of 61
cm above the stored liquid surface.
(B) There are to be no holes, tears, or other openings in the shoe,
seal fabric, or seal envelope.
(ii) The secondary seal is to meet the following requirements:
(A) The secondary seal is to be installed above the primary seal so
that it completely covers the space between the roof edge and the tank
wall except as provided in paragraph (b)(2)(iii) of this section.
(B) The accumulated area of gaps between the tank wall and the
secondary seal shall not exceed 21.2 cm\2\ per meter of tank diameter,
and the width of any portion of any gap shall not exceed 1.27 cm.
(C) There are to be no holes, tears, or other openings in the seal
or seal fabric.
(iii) If a failure that is detected during inspections required in
paragraph (b)(1) of Sec. 60.113b(b) cannot be repaired within 45 days
and if the vessel cannot be emptied within 45 days, a 30-day extension
may be requested from the Administrator in the inspection report
required in Sec. 60.115b(b)(4). Such extension request must include a
demonstration of unavailability of alternate storage capacity and a
specification of a schedule that will assure that the control equipment
will be repaired or the vessel will be emptied as soon as possible.
(5) Notify the Administrator 30 days in advance of any gap
measurements required by paragraph (b)(1) of this section to afford the
Administrator the opportunity to have an observer present.
(6) Visually inspect the external floating roof, the primary seal,
secondary seal, and fittings each time the vessel is emptied and
degassed.
(i) If the external floating roof has defects, the primary seal has
holes, tears, or other openings in the seal or the seal fabric, or the
secondary seal has holes, tears, or other openings in the seal or the
seal fabric, the owner or operator shall repair the items as necessary
so that none of the conditions specified in this paragraph exist before
filling or refilling the storage vessel with VOL.
(ii) For all the inspections required by paragraph (b)(6) of this
section, the owner or operator shall notify the Administrator in writing
at least 30 days prior to the filling or refilling of each storage
vessel to afford the Administrator the opportunity to inspect the
storage vessel prior to refilling. If the inspection required by
paragraph (b)(6) of this section is not planned and the owner or
operator could not have known about the inspection 30 days in
[[Page 366]]
advance of refilling the tank, the owner or operator shall notify the
Administrator at least 7 days prior to the refilling of the storage
vessel. Notification shall be made by telephone immediately followed by
written documentation demonstrating why the inspection was unplanned.
Alternatively, this notification including the written documentation may
be made in writing and sent by express mail so that it is received by
the Administrator at least 7 days prior to the refilling.
(c) The owner or operator of each source that is equipped with a
closed vent system and control device as required in Sec. 60.112b
(a)(3) or (b)(2) (other than a flare) is exempt from Sec. 60.8 of the
General Provisions and shall meet the following requirements.
(1) Submit for approval by the Administrator as an attachment to the
notification required by Sec. 60.7(a)(1) or, if the facility is exempt
from Sec. 60.7(a)(1), as an attachment to the notification required by
Sec. 60.7(a)(2), an operating plan containing the information listed
below.
(i) Documentation demonstrating that the control device will achieve
the required control efficiency during maximum loading conditions. This
documentation is to include a description of the gas stream which enters
the control device, including flow and VOC content under varying liquid
level conditions (dynamic and static) and manufacturer's design
specifications for the control device. If the control device or the
closed vent capture system receives vapors, gases, or liquids other than
fuels from sources that are not designated sources under this subpart,
the efficiency demonstration is to include consideration of all vapors,
gases, and liquids received by the closed vent capture system and
control device. If an enclosed combustion device with a minimum
residence time of 0.75 seconds and a minimum temperature of 816 [deg]C
is used to meet the 95 percent requirement, documentation that those
conditions will exist is sufficient to meet the requirements of this
paragraph.
(ii) A description of the parameter or parameters to be monitored to
ensure that the control device will be operated in conformance with its
design and an explanation of the criteria used for selection of that
parameter (or parameters).
(2) Operate the closed vent system and control device and monitor
the parameters of the closed vent system and control device in
accordance with the operating plan submitted to the Administrator in
accordance with paragraph (c)(1) of this section, unless the plan was
modified by the Administrator during the review process. In this case,
the modified plan applies.
(d) The owner or operator of each source that is equipped with a
closed vent system and a flare to meet the requirements in Sec. 60.112b
(a)(3) or (b)(2) shall meet the requirements as specified in the general

(1) A report containing the measurements required by Sec. 60.18(f)
(1), (2), (3), (4), (5), and (6) shall be furnished to the Administrator
as required by Sec. 60.8 of the General Provisions. This report shall
be submitted within 6 months of the initial start-up date.
(2) Records shall be kept of all periods of operation during which
the flare pilot flame is absent.
(3) Semiannual reports of all periods recorded under Sec.
60.115b(d)(2) in which the pilot flame was absent shall be furnished to
the Administrator.
Sec. 60.116b Monitoring of operations.
(a) The owner or operator shall keep copies of all records required
by this section, except for the record required by paragraph (b) of this
section, for at least 2 years. The record required by paragraph (b) of
this section will be kept for the life of the source.
(b) The owner or operator of each storage vessel as specified in
Sec. 60.110b(a) shall keep readily accessible records showing the
dimension of the storage vessel and an analysis showing the capacity of
the storage vessel.
(c) Except as provided in paragraphs (f) and (g) of this section,
the owner or operator of each storage vessel either with a design
capacity greater than or equal to 151 m\3\ storing a liquid with a
maximum true vapor pressure greater than or equal to 3.5 kPa or with a
design capacity greater than or equal to 75 m\3\ but less than 151 m\3\
storing a liquid with a maximum true vapor pressure greater than or
equal to 15.0 kPa shall maintain a record of the VOL stored, the period
of storage, and the maximum true vapor pressure of that VOL during the
respective storage period.
(d) Except as provided in paragraph (g) of this section, the owner
or operator of each storage vessel either with a design capacity greater
than or equal to 151 m\3\ storing a liquid with a maximum true vapor
pressure that is normally less than 5.2 kPa or with a design capacity
greater than or equal to 75 m\3\ but less than 151 m\3\ storing a liquid
with a maximum true vapor pressure that is normally less than 27.6 kPa
shall notify the Administrator within 30 days when the maximum true
vapor pressure of the liquid exceeds the respective maximum true vapor
vapor pressure values for each volume range.
(e) Available data on the storage temperature may be used to
determine the maximum true vapor pressure as determined below.
(1) For vessels operated above or below ambient temperatures, the
maximum true vapor pressure is calculated based upon the highest
expected calendar-month average of the storage temperature. For vessels
operated at ambient temperatures, the maximum true vapor pressure is
calculated based upon the maximum local monthly average ambient
temperature as reported by the National Weather Service.
(2) For crude oil or refined petroleum products the vapor pressure
may be obtained by the following:
(i) Available data on the Reid vapor pressure and the maximum
expected storage temperature based on the highest expected calendar-
month average temperature of the stored product may be used to determine
the maximum true vapor pressure from nomographs contained in API
Bulletin 2517 (incorporated by reference--see Sec. 60.17), unless the
Administrator specifically requests that the liquid be sampled, the
actual storage temperature determined, and the Reid vapor pressure
determined from the sample(s).
(ii) The true vapor pressure of each type of crude oil with a Reid
vapor pressure less than 13.8 kPa or with physical properties that
preclude determination by the recommended method is to be determined
from available data and recorded if the estimated maximum true vapor
pressure is greater than 3.5 kPa.
(3) For other liquids, the vapor pressure:
(i) May be obtained from standard reference texts, or
(ii) Determined by ASTM D2879-83, 96, or 97 (incorporated by
reference--see Sec. 60.17); or
(iii) Measured by an appropriate method approved by the
Administrator; or
(iv) Calculated by an appropriate method approved by the
Administrator.
[[Page 369]]
(f) The owner or operator of each vessel storing a waste mixture of
indeterminate or variable composition shall be subject to the following
requirements.
(1) Prior to the initial filling of the vessel, the highest maximum
true vapor pressure for the range of anticipated liquid compositions to
be stored will be determined using the methods described in paragraph
(e) of this section.
(2) For vessels in which the vapor pressure of the anticipated
liquid composition is above the cutoff for monitoring but below the
cutoff for controls as defined in Sec. 60.112b(a), an initial physical
test of the vapor pressure is required; and a physical test at least
once every 6 months thereafter is required as determined by the
following methods:
(i) ASTM D2879-83, 96, or 97 (incorporated by reference--see Sec.
60.17); or
(ii) ASTM D323-82 or 94 (incorporated by reference--see Sec.
60.17); or
(iii) As measured by an appropriate method as approved by the
Administrator.
(g) The owner or operator of each vessel equipped with a closed vent
system and control device meeting the specification of Sec. 60.112b or
with emissions reductions equipment as specified in 40 CFR 65.42(b)(4),
(b)(5), (b)(6), or (c) is exempt from the requirements of paragraphs (c)
and (d) of this section.
