(C) Storage of volatile organic liquids in fixed roof tanks.
(1)
Except where exempted under paragraph (C)(5) of this rule, no owner or operator
of a fixed roof tank shall place, store, or hold any volatile organic liquid
with a maximum true vapor pressure which is greater than 0.75 pounds per square
inch absolute, but less than 11.1 pounds per square inch absolute, in any such
tank, after the date specified in paragraph (G) of this rule, unless such tank
is designed or equipped with one of the following vapor control systems:
(a) An internal floating roof that meets
paragraph (C)(3) of this rule.
(b)
A closed vent system and control device that meets paragraph (C)(4) of this

(2) Except where
exempted under paragraph (C)(5) of this rule, no owner or operator of a fixed
roof tank shall place, store, or hold any volatile organic liquid with a
maximum true vapor pressure which is equal to or greater than 11.1 pounds per
square inch absolute, in any such tank, after the date specified in paragraph
(G) of this rule, unless such tank is designed or equipped with a closed vent
system and control device that meets paragraph (C)(4) of this rule.
(3) If the fixed roof tank is equipped with
an internal floating roof, the following shall be met:
(a) The internal floating roof shall rest or
float on the liquid surface (but not necessarily in complete contact with it)
inside a storage vessel that has a fixed roof. The internal floating roof shall
float on the liquid surface at all times, except during initial fill and during
those intervals when the storage vessel is completely emptied or subsequently
emptied and refilled. When the roof is resting on the leg supports, the process
of filling, emptying, or refilling shall be continuous and shall be
accomplished as rapidly as possible.
(b) Each internal floating roof shall be
equipped with one of the following closure devices between the wall of the
storage vessel and the edge of the internal floating roof:
(i) A foam or liquid-filled seal mounted in
contact with the liquid (liquidmounted seal). A liquid-mounted seal means a
foam or liquid-filled seal mounted in contact with the liquid, between the wall
of the storage vessel and the floating roof, and extending continuously around
the circumference of the tank.
(ii)
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 shall be continuous.
(iii) A
mechanical shoe seal. A mechanical shoe seal is a metal sheet held vertically
against the wall of the storage vessel by springs or weighted levers and is
connected by braces to the floating roof. A flexible coated fabric (envelope)
spans the annular space between the metal sheet and the floating
roof.
(c) Automatic
bleeder vents shall be equipped with a gasket and are to be closed at all times
when the roof is floating except when the roof is being floated off or is being
landed on the roof leg supports. Rim space vents shall be equipped with a
gasket and are to be set to open only when the internal floating roof is not
floating or at the manufacturer's recommended setting.
(d) Each opening in a non-contact internal
floating roof, except for automatic bleeder vents (vacuum breaker vents) and
the rim space vents, shall provide a projection below the liquid
surface.
(e) Each opening in the
internal floating roof, except for leg sleeves, automatic bleeder vents, rim
space vents, column wells, ladder wells, sample wells, and stub drains, shall
be equipped with a cover or lid which shall be maintained in a closed position
at all times (i.e., no visible gap) except when the device is in actual use.
The cover or lid shall be equipped with a gasket. Covers on each access hatch
and automatic gauge float well shall be bolted except when they are in
use.
(f) The sample well, which
penetrates the internal floating roof for the purpose of sampling, shall have a
slit fabric cover that covers at least ninety per cent of the
opening.
(g) Each penetration of
the internal floating roof that allows for passage of a ladder shall have a
gasketed sliding cover.
(h)
Inspection.
The owner or operator of each storage vessel equipped with an internal floating roof, shall comply with the following:
(i) 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 a volatile organic liquid. 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.
(ii) 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 twelve
months after initial fill. If the internal floating roof is not resting on the
surface of the volatile organic liquid 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 forty-five days. If a failure
that is detected during inspections required in this paragraph cannot be
repaired within forty-five days and if the vessel cannot be emptied within
forty-five days, a thirty-day extension may be requested from the director in
the inspection report required in paragraph (C)(3)(j)(iii) of this rule. Such a
request for an extension shall document that alternate storage capacity is
unavailable and specify a schedule of actions the company will take that will
ensure that the control equipment will be repaired or the vessel will be
emptied within thirty days.
(iii)
For vessels equipped with both primary and secondary seals, visually inspect
the vessel as follows:
(a) As specified in
paragraph (C)(3)(h)(iv) of this rule at least every five years.
(b) At least once every twelve months as
specified in paragraph (C) (3)(h)(ii) of this rule.
(iv) 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 ten per cent 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 a volatile organic liquid. In no event shall inspections conducted
in accordance with this provision occur at intervals greater than ten years in
the case of vessels conducting the annual visual inspection as specified in
paragraphs (C)(3)(h)(ii) and (C)(3)(h)(iii)(b) of this rule and at intervals no
greater than five years in the case of vessels specified in paragraph
(C)(3)(h)(iii)(a) of this rule.
(i) Notify the director in writing at least
thirty days prior to the filling or refilling of each storage vessel for which
an inspection is required by paragraphs (C)(3)(h)(i) and (C)(3)(h)(iv) of this
rule to afford the director or the director's authorized designee the
opportunity to have an observer present. If the inspection required by
paragraph (C)(3)(h)(iv) of this rule is not planned and the owner or operator
could not have known about the inspection thirty days in advance of refilling
the tank, the owner or operator shall notify the director at least seven 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 director at least seven days prior to the
refilling.
(j) Recordkeeping and
reporting.
The owner or operator of each storage vessel equipped with an internal floating roof shall keep records and furnish reports in accordance with the following:
(i) Furnish the
director with a report that describes the control equipment and certifies that
the control equipment meets the specifications of paragraph (C) of this rule.
This report shall be submitted in accordance with the requirements specified in
paragraph (H) of this rule.
(ii)
Keep a record of each inspection performed as required by paragraphs
(C)(3)(h)(i) to (C)(3)(h)(iv) of this rule. Each record shall identify the
storage vessel for which the inspection was performed and shall contain the
date the vessel was inspected and the observed condition of each component of
the control equipment (seals, internal floating roof, and fittings).
(iii) If any of the conditions described in
paragraph (C)(3)(h)(ii) of this rule are detected during the annual visual
inspection required by paragraph (C)(3)(h)(ii) of this rule, a report shall be
furnished to the director within thirty days of the inspection. Each report
shall identify the storage vessel, the nature of the defects, and the date the
storage vessel was emptied or the nature of and date the repair was
made.
(k) After each
inspection required by paragraph (C)(3)(h)(iii) of this rule that finds holes
or tears in the seal or seal fabric, or defects in the internal floating roof,
or other control equipment defects listed in paragraph (C) (3)(h)(ii) or
(C)(3)(h)(iv) of this rule, a report shall be furnished to the director within
thirty days of the inspection. The report shall identify the storage vessel and
the reason it did not meet the specifications of paragraph (C)(3) of this rule
and list each repair made.
(l) The
owner or operator shall keep copies of all reports and records required by
paragraph (C)(3)(j) of this rule for at least five years.
(4) If the fixed roof tank is equipped with a
closed vent system and control device, as required by paragraph (C)(1)(b) or
(C)(2) of this rule, the following specifications shall be met:
(a) The closed vent system shall be designed
to collect all VOC vapors and gases discharged from the storage vessel and
operated with no detectable emissions, as indicated by an instrument reading of
less than five hundred parts per million above background and visual
inspections, as determined by the methods specified in
40 CFR
60.485(c).
(b) If a control device other than a flare is
employed, the control device shall be designed and operated to reduce inlet VOC
emissions by ninety five per cent or greater. The control efficiency shall be
determined in accordance with paragraph (C) of rule
3745-21-10 of the Administrative
Code.
(c) If a flare is used as the
control device, it shall meet the specifications described in the general
control device requirements specified in
40 CFR
60.18.
(d) The owner or operator of each tank that
is equipped with a closed vent system and control device other than a flare, to
meet the control requirements as required in paragraph (C)(4) of this rule,
shall meet the specifications identified in paragraphs (C)(4)(a) and (C)(4)(b)
of this rule and shall submit, for approval by the director, an operating plan
containing the following information:
(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 rule, 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 eight hundred sixteen degrees
centigrade is used to meet the ninety-five per cent control requirement,
documentation that those conditions will exist during all loading conditions 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).
(e) 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 director in
accordance with paragraph (C)(4)(d) of this rule, unless the plan was modified
by the director during the review process, in which case, the modified plan
applies. The operating plan required by paragraph (C)(4)(d) of this rule shall
be maintained by the owner or operator for the life of the control equipment
and shall be made available to the director upon request.
(f) Any approval granted by the director in
accordance with paragraph (C)(4)(d) of this rule shall be approved by the USEPA
as a revision of the Ohio state implementation plan.
(g) The owner or operator of each source that
is equipped with a closed vent system and a flare, to meet the control

supports.
(ii) Measure the seal
gaps around the entire circumference of the tank, in each place where a
one-eighth inch diameter uniform probe passes freely (without forcing or
binding against the 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 (D)(b)(ii) of this rule shall be determined by using
probes of various widths to measure accurately the actual distance from the
tank wall to the seal and then multiplying each such width by its respective
circumferential distance.
(iv) Add
the gap surface area of each gap location for the primary seal and the
secondary seal individually and divide the sum for each by the nominal diameter
of the tank and compare each ratio to the respective standards in paragraph
(D)(3)(c)(i) or (D)(3)(c)(ii) of this rule.
