substitution of sampling equipment that has been demonstrated for a
particular sample matrix and use of a different impinger absorbing
solution;
    (2) Changes in sample recovery procedures and analytical
techniques, such as changes to sample holding times and use of a
different analytical finish with proven capability for the analyte of
interest; and
    (3) ``Combining'' a federally required method with another proven
method for application to processes emitting multiple pollutants.
    Internal floating roof or IFR means a floating roof located in a
storage vessel with a fixed roof. An EFR located in a storage vessel to
which a fixed roof has been added is considered to be an internal
floating roof.
    Internal guidepole sleeve means a cylindrical device that fits on
the inside of a slotted guidepole and blocks the vapor emission pathway
from the interior of the guidepole through the guidepole slots to the
outside air.
    Liquid-mounted seal means a resilient or liquid-filled rim seal
designed to contact the stored liquid.
    Liquids dripping means any visible leakage from the seal including
dripping, spraying, misting, clouding and ice formation. Indications of
liquids dripping include puddling or new stains that are indicative of
an existing evaporated drip.
    Major change to monitoring means a modification to federally
required monitoring that uses ``unproven technology or procedures''
(not generally accepted by the scientific community) or is an entirely
new method (sometimes necessary when the required monitoring is
unsuitable). A major change to monitoring may be site-specific or may
apply to one or more source categories and will almost always set a
national precedent. Examples of major changes to monitoring include,
but are not limited to:
    (1) Use of a new monitoring approach developed to apply to a
control technology not contemplated in the applicable regulation;
    (2) Use of a predictive emission monitoring system (PEMS) in place
of a required CEMS;
    (3) Use of alternative calibration procedures that do not involve
calibration gases or test cells;
    (4) Use of an analytical technology that differs from that
specified by a performance specification;
    (5) Decreased monitoring frequency for a CEMS, continuous opacity
monitoring system, PEMS or CPMS;
    (6) Decreased monitoring frequency for a leak detection and repair
program; and
    (7) Use of alternative averaging times for reporting purposes.
    Major change to test method means a modification to a federally
enforceable test method that uses ``unproven technology or procedures''
(not generally accepted by the scientific community) or is an entirely
new method (sometimes necessary when the required test method is
unsuitable). A major change to a test method may be site-specific or
may apply to one or more sources or source categories, and will almost
always set a national precedent. In order to be approved, a major
change must be validated according to EPA Method 301 (40 CFR part 63,
appendix A). Examples of major changes to a test method include, but
are not limited to:
    (1) Use of an unproven analytical finish;
    (2) Use of a method developed to fill a test method gap;
    (3) Use of a new test method developed to apply to a control
technology not contemplated in the applicable regulation; and
    (4) Combining two or more sampling/analytical methods (at least one

unproven) into one for application to processes emitting multiple
pollutants.
    Maximum representative operating conditions means process operating
conditions that result in the most challenging condition for the
control device. The most challenging condition for the control device
may include, but is not limited to, the highest hazardous air pollutant
(HAP) mass loading rate to the control device or the highest HAP mass
loading rate of constituents that approach the limits of solubility for
scrubbing media.
    Maximum true vapor pressure or MTVP means the equilibrium partial
pressure exerted by the total regulated material in the stored or
transferred liquid at the temperature equal to the highest calendar-
month average of the liquid storage or transfer temperature for liquids
stored or transferred above or below the ambient temperature or at the
local maximum monthly average temperature, as reported by the National
Weather Service, for liquids stored or transferred at the ambient
temperature, as determined using methods specified in Sec.  65.306.
    Mechanical shoe seal or metallic shoe seal means a rim seal
consisting of a band of metal (or other suitable material) as the
sliding contact with the wall of the storage vessel, and a fabric seal
to close the annular space between the band and the rim of the floating

that are overlapped or joined together to form a ring. The sheets are
held vertically against the wall of the storage vessel by springs,
weighted levers or other mechanisms and are connected to the floating
roof by braces or other means. The lower end of the band extends into
the stored liquid.
    Minor change to monitoring means:
    (1) A modification to federally required monitoring that:
    (i) Does not decrease the stringency of the compliance and
enforcement measures for the relevant standard;
    (ii) Has no national significance (e.g., does not affect
implementation of the applicable regulation for other regulated
sources, does not set a national precedent and individually does not
result in a revision to the monitoring requirements); and
    (iii) Is site-specific, made to reflect or accommodate the
operational characteristics, physical constraints or safety concerns of
a regulated source.
    (2) Examples of minor changes to monitoring include, but are not
limited to:
    (i) Modifications to a sampling procedure, such as use of an
improved sample conditioning system to reduce maintenance requirements;
    (ii) Increased monitoring frequency; and
    (iii) Modification of the environmental shelter to moderate
temperature fluctuation and, thus, protect the analytical
instrumentation.
    Minor change to test method means:
    (1) A modification to a federally enforceable test method that:
    (i) Does not decrease the stringency of the emission limitation or
standard;
    (ii) Has no national significance (e.g., does not affect
implementation of the applicable regulation for other regulated
sources, does not set a national precedent and individually does not
result in a revision to the test method); and
    (iii) Is site-specific, made to reflect or accommodate the
operational characteristics, physical constraints or safety concerns of
a regulated source.
    (2) Examples of minor changes to a test method include, but are not
limited to:
    (i) Field adjustments in a test method's sampling procedure, such
as a modified sampling traverse, or location to avoid interference from
an obstruction in the stack, increasing the sampling time or volume,
use of additional impingers for a high moisture situation, accepting
particulate emission results for a test run that was conducted with a
lower-than-specified temperature, substitution of a material in the
sampling train that has been demonstrated to be more inert for the
sample matrix; and
    (ii) Changes in recovery and analytical techniques, such as a
change in quality control/quality assurance requirements needed to
adjust for analysis of a certain sample matrix.
    Monitoring means the collection and use of measurement data or
other information to control the operation of a process or pollution
control device or to verify a work practice standard relative to
assuring compliance with applicable requirements. Monitoring is
composed of four elements:
    (1) Indicator(s) of performance--the parameter or parameters you
measure or observe for demonstrating proper operation of the pollution
control measures or compliance with the applicable emissions limitation
or standard. Indicators of performance may include direct or predicted
emissions measurements (including opacity), operational parametric
values that correspond to process or control device (and capture
system) efficiencies or emissions rates and recorded findings of
inspection of work practice activities, materials tracking or design
characteristics. Indicators may be expressed as a single maximum or
minimum value, a function of process variables (for example, within a
range of pressure drops), a particular operational or work practice
status (for example, a damper position, completion of a waste recovery
task, materials tracking) or an interdependency between two or among
more than two variables.
    (2) Measurement techniques--the means by which you gather and
record information of or about the indicators of performance. The
components of the measurement technique include the detector type,
location and installation specifications, inspection procedures, and
quality assurance and quality control measures. Examples of measurement
techniques include CEMS, continuous opacity monitoring systems, CPMS,
and manual inspections that include making records of process
conditions or work practices.
    (3) Monitoring frequency--the number of times you obtain and record
monitoring data over a specified time interval. Examples of monitoring
frequencies include at least four points equally paced for each hour
for continuous emissions or parametric monitoring systems, at least
every 10 seconds for continuous opacity monitoring systems and at least
once per operating day (or week, month, etc.) for work practice or
design inspections.
    (4) Averaging time--the period over which you average and use data
to verify proper operation of the pollution control approach or
compliance with the emissions limitation or standard. Examples of
averaging time include a 3-hour average in units of the emissions
limitation, a 30-day rolling average emissions value, a daily average
of a control device operational parametric range and an instantaneous
alarm.
    Non-repairable means that it is technically infeasible to repair a
piece of equipment from which a leak has been detected without a
process unit shutdown.
    Nonstandard batch means a batch process that is operated outside of
the range of operating conditions that are documented in an existing
operating scenario, but is still a reasonably anticipated event. For
example, a nonstandard batch occurs when additional processing or
processing at different operating conditions must be conducted to
produce a product that is normally produced under the conditions
described by the standard batch. A nonstandard batch may be necessary,
as a result of a malfunction, but it is not itself a malfunction.
    Open-ended valve or line means any valve, except relief valves,
having one

side of the valve seat in contact with process fluid and one side open
to atmosphere, either directly or through any length of open piping. An
open-ended valve or line with a cap, blind flange, plug or second valve
on the side that would be otherwise open to the atmosphere is still
considered an open-ended valve or line.
    Operating block means a period of time that is equal to the time
from the beginning to end of batch process operations within a process.
    Optical gas imaging instrument means an instrument capable of
producing an image that makes visible emissions that otherwise may be
invisible to the naked eye.
    Owner or operator means any person who owns, leases, operates,
controls or supervises a regulated source or a stationary source of
which a regulated source is a part.
    Performance test means the collection of data resulting from the
execution of a test method (usually three emission test runs) used to
demonstrate compliance with a relevant emission limit, as specified in
the performance test section of 40 CFR part 65, subpart M or in the
referencing subpart.
    Pole float means a float located inside a guidepole that floats on
the surface of the stored liquid. The rim of the float has a wiper or
seal that extends to the inner surface of the pole.
    Pole sleeve means a device that extends from either the cover or
the rim of an opening in a floating roof deck to the outer surface of a
pole that passes through the opening. The sleeve extends into the
stored liquid.
    Pole wiper means a seal that extends from either the cover or the
rim of an opening in a floating roof deck to the outer surface of a
pole that passes through the opening.
    Polymerizing monomer means a compound that may form polymer buildup
in pump mechanical seals resulting in rapid mechanical seal failure.
    Pressure release means the emission of materials resulting from the
system pressure being greater than the set pressure of the PRD. This
release may be one release or a series of releases over a short time
period.
    Pressure relief device (PRD) means a safety device used to prevent
operating pressures from exceeding the maximum allowable working
pressure of the process component. Examples of pressure relief devices
are a spring-loaded pressure relief valve and a rupture disk. Except
for devices used to comply with the vapor balancing requirements in
Sec.  65.320(c), devices that are actuated either by a pressure of less
than or equal to 2.5 psig or by a vacuum are not pressure relief
devices.
    Pressure vessel means a storage vessel that is used to store
liquids or gases and is designed not to vent to the atmosphere as a
result of compression of the vapor headspace in the pressure vessel
during filling of the pressure vessel to its design capacity.
    Primary fuel means the fuel that provides the principal heat input
to a combustion device. To be considered primary, the fuel must be able
to sustain operation without the addition of other fuels.
    Process condenser means a condenser whose primary purpose is to
recover material as an integral part of a regulated batch process. All
condensers recovering condensate from a regulated batch process at or
above the boiling point or all condensers in line prior to a vacuum
source, are considered process condensers. Typically, a primary
condenser or condensers in series, are considered to be integral to the
batch regulated process if they are capable of and normally used for
the purpose of recovering chemicals for fuel value (i.e., net positive
heating value), use, reuse or for sale for fuel value, use or reuse.
This definition does not apply to a condenser that is used to remove
materials that would hinder performance of a downstream recovery device
as follows:
    (1) To remove water vapor that would cause icing in a downstream
condenser.
    (2) To remove water vapor that would negatively affect the
adsorption capacity of carbon in a downstream carbon adsorber.
    (3) To remove high molecular weight organic compounds or other
organic compounds that would be difficult to remove during regeneration
of a downstream carbon adsorber.

process to collect material discharged from a feedstock storage vessel
or component within the process before the material is transferred to
other components within the process or a product storage vessel.
Examples of process tanks include surge control vessels, bottoms
receivers and weigh tanks. In addition, all vessels in which a unit
operation is conducted, including, but not limited to reaction, mixing
and separation are process tanks.
    Process unit means, unless specified otherwise in the applicable
referencing subpart, the components assembled to produce an intended
intermediate or final product. A process unit can operate independently
if supplied with sufficient feed or raw materials and sufficient
storage facilities for the product. All components located within the
fence line of the plant site are included in the process unit.
Components located offsite are not included within any process unit.
    Process unit shutdown means a work practice or operational
procedure that stops production from a process unit, or part of a
process unit during which it is technically feasible to clear process
material from a process unit, or part of a process unit, consistent
with safety constraints and during which, repairs can be affected. The
following are not considered process unit shutdowns:
    (1) An unscheduled work practice or operations procedure that stops
production from a process unit, or part of a process unit, for less
than 24 hours.
    (2) An unscheduled work practice or operations procedure that would
stop production from a process unit, or part of a process unit, for a
shorter period of time than would be required to clear the process
unit, or part of the process unit of materials and start up the unit,
and would result in greater emissions than delay of repair of leaking
components, until the next scheduled process unit shutdown.
    (3) The use of spare equipment and technically feasible bypassing
of equipment without stopping production.
    Referencing subpart means the subpart that directs you to comply
with one or more applicable Uniform Standards (subparts I through M of
this part). A referencing subpart for one Uniform Standard may also be
a referencing subpart for another Uniform Standard.
    Regulated material means chemicals or groups of chemicals (such as
volatile organic compounds or HAP) that are regulated by the
referencing subpart.
    Regulated source means the stationary source, the group of
stationary sources or the portion of a stationary source that is
regulated by a relevant standard or other requirement established,
pursuant to a referencing subpart.
    Repair means that:
    (1) If indications of a potential leak or liquids dripping are
observed during sensory monitoring or a visual inspection, then the
equipment, seal, fitting or other emissions source is adjusted, or
otherwise altered, to eliminate the indications of a potential leak or
liquids dripping.

    (2) If a leak is detected by instrument monitoring, then the
equipment, seal, fitting or other emissions source is adjusted or
otherwise altered to eliminate a leak, as defined in the applicable
sections of subparts I through M of this part and the emissions source
is monitored, as specified in Sec.  65.431(a) and (b) to verify that
emissions are below the applicable instrument reading that defines a
leak.
    (3) If a leak is detected by a sensor or by failure of one or more
design or inspection criteria, then the equipment, seal, fitting or
other emissions source is adjusted, or otherwise altered, to return the
emissions source to conditions such that the sensor no longer indicates
a leak or that the emissions source is meeting the design or inspection
criteria, as applicable.
    (4) If a leak is detected by optical gas imaging, then the
equipment, seal, fitting or other emissions source is adjusted, or
otherwise altered, to eliminate the leak and the emissions source is
monitored, as specified in Sec.  65.450(b)(2) to verify that the leak
can no longer be imaged by the optical gas imaging instrument.
    (5) Repair does not mean repairs to CEMS or CPMS.
    Rim seal means a device attached to the rim of a floating roof deck
that spans the annular space between the deck and the wall of the
storage vessel. When a floating roof has only one such device, it is a
primary seal; when there are two seals (one mounted above the other),
the lower seal is the primary seal and the upper seal is the secondary
seal.
    Run means one of a series of emission or other measurements needed
to determine emissions for a representative operating period or cycle,
as specified in 40 CFR part 65, subpart M or in the referencing
subpart. Unless otherwise specified, a run may be either intermittent
or continuous within the limits of good engineering practice.
    Run down tank means a tank in which the product from a still,
agitator or other processing equipment is received, and from which, the
product is pumped to a storage vessel.
    Rupture disk means a PRD that consists of a diaphragm held between
flanges. The diaphragm splits when the pressure on the process side
exceeds the design set pressure.
    Sampling connection system means an assembly of piping and
equipment within a process unit used during periods of representative
operation to take samples of the process fluid. Lines that convey
samples to analyzers and analyzer bypass lines are part of sampling
connection systems. A device or apparatus used to take non-routine grab
samples is not considered a sampling connection system.
    Secondary fuel means a fuel fired through a burner other than the
primary fuel burner that provides supplementary heat, in addition to
the heat provided by the primary fuel.
    Sensor means a device that measures a physical quantity or the
change in a physical quantity, such as temperature, pressure, flow
rate, pH or liquid level.
    Sensory monitoring means visual, audible, olfactory or any other
detection method used to determine a potential leak to the atmosphere.
    Set pressure means the pressure at which a properly operating PRD
begins to open to relieve atypical process system operating pressure.
    Slotted guidepole means a guidepole or gaugepole that has slots or
holes through the wall of the pole. The slots or holes allow the stored
liquid to flow into the pole at liquid levels above the lowest
operating level.
    Small boiler or process heater means a boiler or process heater
that has a design capacity less than 44 megawatts, and in which the
vent stream is introduced with the combustion air or as a secondary
fuel.
    Startup means the setting into operation of a process unit, a piece
of equipment or a control device that is subject to the Uniform
Standards.
    Storage capacity means the internal volume of a storage vessel from
the floor to the top of the shell. For example, for a flat-bottomed
storage vessel, the storage capacity is determined by multiplying the
internal cross-sectional area of the storage vessel by the height of
the shell. The calculation must be modified, as necessary, to account
for floors that are not flat (e.g., slope-bottomed, cone-up or cone-
down).
    Storage vessel means a stationary unit that is constructed of non-
earthen materials (such as wood, concrete, steel, fiberglass or
plastic), which provides structural support and is designed to hold an
accumulation of liquids or other materials. The following are not
considered storage vessels:
    (1) Vessels permanently attached to motor vehicle, such as trucks,
railcars, barges or ships;
    (2) Vessels storing liquid that contains regulated material only as
an impurity;
    (3) Wastewater tanks; and
    (4) Process tanks.
    Submerged loading means the filling of a transport vehicle through
a submerged fill pipe whose discharge is no more than 6 inches from the
bottom of the tank. Bottom loading of transport vehicles is included in
this definition.
    Supplemental combustion air means the air that is added to a vent
stream after the vent stream leaves the unit operation. Air that is
part of the vent stream as a result of the nature of the unit operation
is not considered supplemental combustion air. Air required to operate
combustion device burner(s) is not considered supplemental combustion
air. Air required to ensure the proper operation of catalytic
oxidizers, to include the intermittent addition of air upstream of the
catalyst bed to maintain a minimum threshold flow rate through the
catalyst bed or to avoid excessive temperatures in the catalyst bed, is
not considered to be supplemental combustion air.
    Surge control vessel means feed drums, recycle drums and
intermediate vessels as part of any continuous operation. Surge control
vessels are used within a process unit when in-process storage, mixing
or management of flow rates or volumes is needed to introduce material
into continuous operations.

a permanently attached vessel that is designed to carry liquid freight
by rail.
    Thermal oxidizer means a combustion device with an enclosed
combustion chamber (i.e., an enclosed fire box) that is used for
destroying organic compounds. Auxiliary fuel may be used to heat waste
gas to combustion temperatures.
    Transfer operations means the loading into a transport vehicle or
container of organic liquids from a transfer rack.
    Transfer rack means a single system used to load organic liquids
into transport vehicles or containers. It includes all loading and
unloading arms, pumps, meters, shutoff valves, relief valves and other
piping and equipment necessary for the transfer operation. Transfer
equipment and operations that are physically separate (i.e., do not
share common piping, valves and other equipment) are considered to be
separate transfer racks.
    Transport vehicle means a cargo tank or tank car.
    Uniform Standard(s) mean(s) any one or all of subparts I, J, K, L
and M of this part.
    Unslotted guidepole or solid guidepole means a guidepole or
gaugepole that does not have slots or holes through the wall of the
pole at or above the level of the floating roof when it is at its
lowest operating level.

    Wastewater tank means a stationary structure that is designed to
contain an accumulation of wastewater or any liquid or solid material
containing volatile organics that is removed from a wastewater stream
and is constructed of non-earthen materials (e.g., wood, concrete,
steel, plastic) that provides structural support.
    You means an owner or operator of a regulated source under the
Uniform Standards.

Manual of Petroleum Measurement Standards, ``Evaporative Loss from
Floating Roof Tanks'' (incorporated by reference, see Sec.  65.265). If
you need the total vapor pressure of a petroleum liquid mixture (e.g.,
crude oil or gasoline), you must test for Reid vapor pressure and
distillation slope, as applicable, to determine the constants A and B
for the vapor pressure equation. If only part of a mixture is regulated
material, you must test to determine the composition of the stored
liquid. Testing is not required if you determine, based on engineering
judgment, that the mixture contains less than 1-percent regulated
material by weight.
    (3) As determined by the ``American Society for Testing and
Materials Method D2879-83'' (incorporated by reference, see Sec.
65.265).
    (4) As determined using ``Test Method for Vapor Pressure of
Reactive Organic Compounds in Heavy Crude Oil Using Gas
Chromatography'' (incorporated by reference, see Sec.  65.265).
    (5) Any other method approved by the Administrator in accordance
with Sec.  65.250.
    (b) Determine the MTVP for each storage vessel that contains a
regulated material either prior to the required submittal date of your
Notification of Compliance Status or prior to the initial fill with
regulated material, whichever is later.
    (c) Determine the MTVP each time the storage vessel is filled with
a different type of material.
    (d) Determine the MTVP at least annually if the storage vessel
stores a mixture and it was determined to be subject to Sec.  65.305(a)
the last time the MTVP was determined.
    (e) Keep records of each MTVP determination, as specified in Sec.
65.380(b)(2).

Standards and Compliance Requirements for Storage Vessels

Sec.  65.310  What requirements must I meet for an atmospheric storage
vessel equipped with a fixed roof?

    You must equip the storage vessel with a fixed roof and operate in
accordance with paragraphs (a) through (d) of this section.
    (a) Closure requirements. Each opening in the fixed roof must be
equipped with a cover or other type of closure device.
    (b) Operating requirements. (1) Except as specified in paragraph
(b)(2) of this section, the fixed roof must be installed with each
closure device secured in the closed position when the storage vessel
contains regulated material.
    (2) You may open closure devices or remove the fixed roof under the
conditions specified in paragraphs (b)(2)(i) and (ii) of this section.
    (i) A closure device may be opened or the roof may be removed when
needed to provide access for manual operations such as maintenance,
inspection, sampling and cleaning.
    (ii) Opening of a spring-loaded conservation vent or similar type
of device that vents to the atmosphere (or allows air to enter the
storage vessel) is allowed to maintain the tank internal operating
pressure within tank design specifications when loading operations or
diurnal ambient temperature fluctuations cause the pressure inside the
storage vessel to migrate beyond the operating pressure range for the
storage vessel.
    (c) Monitoring requirements. (1) Except as specified in paragraph
(c)(2)

or (3) of this section, monitor each potential source of vapor leakage
from the fixed roof and its closure devices for leaks in accordance
with either paragraph (c)(1)(i) or (ii) of this section. Conduct
monitoring while the storage vessel contains regulated material.
    (i) Monitor using Method 21 of 40 CFR part 60, appendix A-7, in
accordance with Sec.  65.431(a) and (b). A leak is detected if you
obtain an instrument reading greater than 500 parts per million by
volume. Conduct monitoring within 90 days after the initial fill and at
least annually.
    (ii) Monitor in accordance with the protocol for optical gas
imaging, as specified in 40 CFR part 60, appendix K. You may use this
monitoring option only if at least one compound in the emissions can be
detected by the optical gas imaging instrument. A leak is detected if
you observe an image of emissions when using the optical gas imaging
instrument. Conduct monitoring within 90 days after the initial fill
and at least semiannually.
    (2) If you determine parts of the roof are unsafe to monitor using
Method 21 of part 60, appendix A-7, because operating personnel would
be exposed to an imminent or potential danger as a consequence of
complying with such monitoring, then the inspection requirements
specified in paragraph (c)(1)(i) of this section do not apply and you
must comply with the requirements specified in paragraphs (c)(2)(i)
through (iii) of this section.
    (i) You must prepare and maintain at the plant site written
documentation that identifies all parts of the fixed roof and any
closure devices that are unsafe to monitor and explains why such parts
are unsafe to monitor.
    (ii) You must develop and implement a written plan and schedule to
conduct inspections during times when it is safe to do so. The required
inspections must be performed as frequently as practicable, but do not
need to be performed more than annually. Keep a copy of the written
plan and schedule at the plant site, as specified in Sec.
65.380(c)(4).
    (iii) As an alternative to paragraphs (c)(2)(i) and (ii) of this
section, you may monitor the parts of the roof identified in paragraph
(c)(2)(i) of this section by using optical gas imaging, as specified in
paragraph (c)(1)(ii) of this section, if the criteria in paragraph
(c)(1)(ii) of this section and 40 CFR part 60, appendix K, are met.
    (3) No monitoring is required during a calendar year when either of
the conditions in paragraph (c)(3)(i) or (ii) of this section are met.
    (i) The storage vessel stores no regulated material at any time
during the calendar year.
    (ii) The storage vessel is emptied less than 120 days since the
last inspection and no regulated material is stored in the storage
vessel for the remainder of the year.
    (4) Keep records of the date of each inspection, as specified in
Sec.  65.380(c)(1), and keep records of each leak, as specified in
Sec.  65.380(c)(2). Provide notification of each inspection, as
specified in Sec.  65.388(a)(1).
    (d) Repair requirements. When a leak is identified during
monitoring required under paragraph (c) of this section, you must
either complete repairs or completely empty the storage vessel within
45 days. If a repair cannot be completed or the vessel cannot be
completely emptied within 45 days, you may use up to two extensions of
up to 30 additional days each. Keep records documenting each decision
to use an extension, as specified in Sec.  65.380(c)(3). Not repairing
or emptying the storage vessel within the time frame specified in this
paragraph (d) is a deviation and must be reported in your semiannual
periodic report, as specified in Sec.  65.384(a).

Sec.  65.315  What requirements must I meet for an atmospheric storage
vessel with a floating roof?

    You must comply with the requirements in paragraphs (a) through (g)

supported by the leg supports or

other support devices (e.g., hangers from the fixed roof) under the
circumstances specified in paragraphs (b)(1)(i) through (vi) of this
section. Any other floating roof landing event is a deviation and must
be recorded, as specified in Sec.  65.380(d)(1), and reported in your
semiannual periodic report, as specified in Sec.  65.384(b).
    (i) During the initial fill.
    (ii) When necessary for maintenance or inspection, including
refill, provided you also comply with either paragraph (b)(1)(ii)(A) or
(B) of this section.
    (A) If the storage vessel does not need to be completely empty in
order to perform the maintenance or inspection, then refill must begin
no later than 24 hours after the roof is landed. Refill must be
performed in accordance with paragraph (b)(2) of this section.
    (B) If the storage vessel must be completely empty in order to
perform the maintenance or inspection, then actions to completely empty
the storage vessel must begin no later than 24 hours after the roof is
landed. Refill may occur at any time after the storage vessel is
completely empty.
    (iii) When necessary to support a change in service to an

24 hours after the roof is landed.
    (v) When the vapors are routed through a closed vent system to a
non-flare control device that reduces regulated material emissions by
at least 90 percent by weight from the time the floating roof is landed
until the floating roof is within 10 percent by volume of being
refloated. You must comply with the requirements in subpart M of this
part for the closed vent system and the applicable non-flare control
device(s). To demonstrate initial compliance with the 90-percent
reduction requirement, you must conduct either a design evaluation, as
specified in Sec.  65.850, or a performance test, as specified in
Sec. Sec.  65.820 through 65.829.
    (vi) When non-halogenated vapors are routed through a closed vent
system to a flare that reduces regulated material emissions from the
time the floating roof is landed until the floating roof is within 10
percent by volume of being refloated. You must comply with the
requirements in subpart M of this part for the closed vent system and
the requirements of Sec.  63.11(b) of this chapter for the flare.
    (2) Once you start filling or refilling a storage vessel that has a
landed floating roof, you may not suspend filling or refilling until
the roof is floating (except when the quantity of liquid produced in
one batch is insufficient to float the roof, and the output from
additional batches will be added before any material is withdrawn from
the storage vessel), and you may not withdraw liquid from the storage
vessel while simultaneously filling or refilling.
    (3) Each cover over an opening in the floating roof, except for
automatic bleeder vents (vacuum breaker vents) and rim space vents,
must be closed at all times, except when the cover must be open for
access.
    (4) Each automatic bleeder vent (vacuum breaker vent) and rim space
vent must be closed at all times, except when required to be open to
relieve excess pressure or vacuum, in accordance with the
manufacturer's design, and during periods when the floating roof is
allowed to be supported by its legs or other support devices.
    (5) Each guidepole cap and slotted ladder leg cap must be closed at
all times except when gauging the liquid level or taking liquid
samples.
    (c) Inspection requirements. Inspect internal floating roofs in
accordance with Table 2 to this subpart, and inspect external floating
roofs in accordance with Table 3 to this subpart. You must also comply
with paragraphs (c)(1) through (6) of this section, as specified in
Table 2 to this subpart, or Table 3 to this subpart, as applicable. If
a floating roof fails an inspection, comply with the repair
requirements specified in paragraph (d) of this section. Keep records
of the inspections, as specified in Sec.  65.380(d)(2), and report
inspection failures in your annual periodic report, as specified in
Sec.  65.386(a).
    (1) Visually inspect for any of the conditions specified in
paragraphs (c)(1)(i) through (iv) of this section at the frequency
specified in Table 2 to this subpart or Table 3 to this subpart, as
applicable. Observing any of these conditions constitutes an inspection
failure. These inspections may be performed entirely from the top side
of the floating roof, as long as there is visual access to all deck
fittings and the top rim seal specified in paragraph (a) of this
section.
    (i) Stored liquid on the floating roof.
    (ii) Holes or tears in the primary or secondary seal (if one is
present).
    (iii) Floating roof deck, deck fittings or rim seals that are not
functioning as designed (as specified in paragraph (a) of this
section).
    (iv) Failure to comply with the operational requirements of
paragraph (b) of this section.
    (2) If you comply with Option 1 or Option 3 in Table 2 to this
subpart or Option 1 in Table 3 to this subpart, inspect each deck
fitting in accordance with paragraph (c)(2)(i) of this section. If you
comply with Option 2 in Table 2 to this subpart or Option 3 in Table 3
to this subpart, monitor each deck fitting in accordance with paragraph
(c)(2)(iii) of this section. If you comply with Option 2 in Table 3 to
this subpart, monitor each deck fitting in accordance with paragraph
(c)(2)(ii) of this section.
    (i) Measure the gap between each deck fitting gasket or wiper
(required by paragraph (a) of this section) and any surface that it is
intended to seal. The inspector must attempt to slide a \1/8\ inch
diameter probe between the gasket or wiper and the surface against
which it is intended to seal. Each location where the probe passes
freely (without forcing or binding) between the two surfaces
constitutes a gap and an inspection failure.
    (ii) Use Method 21 of 40 CFR part 60, appendix A-7, in accordance
with Sec.  65.431(a) and (b) to monitor all sources of potential vapor
leakage around each fitting. Conduct monitoring only when the roof is
floating on the stored liquid. An instrument reading greater than 500
ppmv constitutes an inspection failure. This option may be used only
for an EFR.
    (iii) Monitor the deck fittings using an optical gas imaging
instrument in accordance with the protocol for optical gas imaging, as
specified in 40 CFR part 60, appendix K. You may use this monitoring
option only if at least one compound in the emissions can be detected
by the optical gas imaging instrument. Conduct monitoring only when the
roof is floating on the stored liquid. Any imaged emissions constitutes
an inspection failure.
    (3) If you comply with Option 1 in Table 3 to this subpart, conduct
seal gap inspections for an EFR by determining the presence and size of
gaps between the rim seals and the wall of the storage vessel in
accordance with the procedures specified in paragraph (c)(3)(i) through
(iv) of this section. Any exceedance of the gap requirements specified
in paragraphs (c)(3)(ii) and (iii) of this section constitutes
inspection failure.
    (i) Rim seals must be measured for gaps at one or more levels while
the EFR is floating, as specified in paragraphs (c)(3)(i)(A) through
(F) of this section.

    (A) The inspector must hold a \1/8\ inch diameter probe vertically
against the inside of the storage vessel wall, just above the rim seal,
and attempt to slide the probe down between the seal and the vessel
wall. Each location where the probe passes freely (without forcing or
binding against the seal) between the seal and the vessel wall
constitutes a gap.
    (B) Determine the length of each gap by inserting the probe into
the gap (vertically) and sliding the probe along the vessel wall in
each direction as far as it will travel freely without binding between
the seal and the vessel wall. The circumferential length along which
the probe can move freely is the gap length.
    (C) Determine the maximum width of each gap by inserting probes of
various diameters between the seal and the vessel wall. The smallest
probe diameter should be \1/8\ inch, and larger probes should have
diameters in increments of \1/8\ inch. The diameter of the largest
probe that can be inserted freely anywhere along the length of the gap
is the maximum gap width.
    (D) Determine the average width of each gap by averaging the
minimum gap width (\1/8\ inch) and the maximum gap width.
    (E) The area of a gap is the product of the gap length and average
gap width.
    (F) Determine the ratio of accumulated area of rim seal gaps to
storage vessel diameter by adding the area of each gap, and dividing
the sum by the nominal diameter of the storage vessel. Determine this
ratio separately for primary and secondary rim seals.
    (ii) The ratio of seal gap area to vessel diameter for the primary
seal must not exceed 10 square inches per foot of vessel diameter, and
the maximum gap width must not exceed 1.5 inches.
    (iii) The ratio of seal gap area to vessel diameter for the
secondary seal must not exceed 1 square inch per foot, and the maximum
gap width must not exceed 0.5 inches, except when you must pull back or
remove the secondary seal to inspect the primary seal.
    (iv) If you determine that it is unsafe to perform an EFR
inspection as specified in paragraph (c)(3)(i) of this section, comply
with the requirements of paragraph (c)(3)(iv)(A) or (B) of this
section.
    (A) Perform the inspection no later than 30 days after the
determination that the floating roof is unsafe.
    (B) Completely empty the storage vessel no later than 45 days after
determining the floating roof is unsafe. If the vessel cannot be
completely emptied within 45 days, you may utilize up to two extensions
of up to 30 additional days each. Keep records documenting each
decision to use an extension, as specified in Sec.  65.380(d)(3).
    (4) If you comply with Option 3 in Table 3 to this subpart, monitor
the circumference of the floating roof when the roof is floating on
stored liquid using an optical gas imaging instrument in accordance
with the procedures specified in the protocol for optical gas imaging
in 40 CFR part 60, appendix K. This monitoring option may be used only
if at least one compound emitted from the storage vessel can be
detected by the optical gas imaging instrument. Any imaged emissions
constitutes an inspection failure.
    (5) If you comply with Option 2 in Table 3 to this subpart, monitor
the interface between the rim seal and the tank shell and any gaps in
the secondary seal using Method 21 of 40 CFR part 60, appendix A-7, in
accordance with Sec.  65.431(a) and (b). Conduct monitoring when the
roof is floating on stored liquid. An instrument reading greater than
500 ppmv constitutes an inspection failure.
    (6) If you comply with Option 2 in Table 2 to this subpart, monitor
the circumference of the IFR using an optical gas imaging instrument in
accordance with the protocol for optical gas imaging, as specified in
40 CFR part 60, appendix K. You may use this monitoring option only if
at least one compound in the emissions can be detected by the optical
gas imaging instrument. Conduct monitoring when the roof is floating on
stored liquid. Any imaged emissions constitutes an inspection failure.
    (d) Repair requirements. Any condition causing an inspection
failure under paragraph (c) of this section that is observed during an
inspection required by paragraph (c) of this section or that you
observe while conducting other activities on the storage vessel (e.g.,
maintenance or sampling) must be repaired, as specified in paragraph
(d)(1) or (2) of this section.
    (1) If the inspection is performed while the storage vessel is
completely empty, you must complete repairs before refilling the
storage vessel with regulated material.
    (2) If the inspection is performed while the storage vessel is not
completely empty, you must complete repairs or completely empty the
storage vessel within 45 days. If a repair cannot be completed or the
vessel cannot be completely emptied within 45 days, you may use up to
two extensions of up to 30 additional days each. Keep records
documenting each decision to use an extension, as specified in Sec.
65.380(d)(3). Not repairing or emptying the storage vessel within the
time frame specified in this paragraph (d) is a deviation and must be
reported in your semiannual periodic report, as specified in Sec.
65.384(a).
    (e) Alternative means of emission limitation. (1) An alternate
device may be substituted for a device specified in paragraph (a) of
this section if the alternate device has an emission factor less than
or equal to the emission factor for the device specified in paragraph
(a) of this section. Requests for the use of alternate devices must be
submitted, as specified in Sec.  65.388(b).
    (2) Tests to determine emission factors for an alternate device
must accurately simulate representative conditions under which the
device and storage vessel will operate, such as wind speed, ambient and
liquid temperatures, pressure or vacuum, and filling and withdrawal
rates, but without creating an unsafe condition. You must include a
copy of the proposed testing protocol in your request.
    (f) Floating roof landing monitoring requirements. (1) Each storage
vessel must be equipped with a system that provides a visual or audible
signal when the floating roof (IFR or EFR) is about to be landed on its
legs or other support devices (e.g., hangers from the fixed roof).
    (2) Each time a floating roof is landed, even if the alarm did not
activate, estimate the amount of regulated material emitted to the
atmosphere during the time the floating roof is landed. Keep records of
this emissions estimate, as specified in Sec.  65.380(d)(1). Report the
estimated emissions in your annual periodic report, as specified in
Sec.  65.386(b).
    (g) Overfill monitoring requirements. (1) Each storage vessel must
be equipped with monitoring equipment that provides a visual or audible
signal when the storage vessel is about to be overfilled.
    (2) Each time the storage vessel is overfilled, estimate the amount
of regulated material spilled and the amount emitted to the atmosphere.
Keep records of this emissions estimate, as specified in Sec.
65.380(i). Report the estimated emissions in your annual periodic
report, as specified in Sec.  65.386(c).

in regulated material service, comply with requirements specified in
Sec.  65.430, unless you are required to comply with Sec.  65.427 for
other emissions conveyed by the fuel gas system (e.g., process vent
emissions).
    (B) For equipment in the fuel gas system that is determined to be
in regulated material service, conduct monitoring and inspections,
while transferring any material that generates vapor that causes the
equipment in the fuel gas system to be in regulated material service.
Alternatively, you may conduct monitoring and inspections when the fuel
gas system is conveying vapors from other emission points that cause
the equipment to be in regulated material service. If equipment in the
fuel gas system contacts regulated material, but is not in regulated
material service, conduct inspections when regulated material vapors
are flowing through the fuel gas system (e.g., when filling any
transport vehicle with liquid that contains regulated material).
