ORGANIC LIQUIDS DISTRIBUTION IMPLEMENTATION TOOL
1.0 PURPOSE
The purpose of this implementation tool is to assist facilities in understanding and
complying with the Organic Liquids Distribution National Emission Standard for
Hazardous Air Pollutants (OLD NESHAP - 40 CFR 63 Subpart EEEE). The OLD
NESHAP was promulgated on February 3, 2004. Amendments to the OLD NESHAP
were published on July 28, 2006, and are integrated into the information presented in this
implementation tool. This implementation tool provides both textual explanations and
flowcharts that can be used to assist a facility in determining the applicability, and
regulatory requirements of the OLD NESHAP. The compliance date for existing sources
was February 3, 2007; and for new sources is upon start-up.
This implementation tool is organized to provide detailed information on various aspects
of the OLD NESHAP.
Section 2 provides explanatory text and flowcharts for determining the
applicability and requirements for storage tanks, transfer racks, containers,
equipment leaks, and equipment not requiring control. This section also provides
a summary and flowchart to assist in the understanding of the compliance timeline
for new/reconstructed sources, existing sources, and area sources. Information on
required notifications as well as continuous compliance is also provided.
Section 3 contains questions and answers to issues that have been raised
throughout the rule making process.
Section 4 contains a detailed glossary of defined terms. The glossary is a
compilation of terms from the OLD NESHAP and other rules that are
incorporated by reference.
The appendices contain all the tables from the OLD NESHAP.
-------
-------
2.0 APPLICABILITY AND REGULATORY SUMMARY FLOW CHARTS
2.1 General Applicability of the Standards
To determine if you are subject to the OLD NESHAP,
you must first determine if you are a major source.
Major sources emit at a minimum 10 tons per year (tpy)
of an individual hazardous air pollutant (HAP) or 25
tpy of a combination of HAP. Subsequently, you must
determine if you have organic liquids and organic
liquids distribution activities at your facility. The
following two bullets provide information on the
definition of organic liquids and organic liquids
distribution activities.
Organic liquids include any non-crude oil liquid
or liquid mixture that contains at least 5 percent
by weight or greater of organic HAP listed in
Table 1 of the OLD NESHAP. Organic liquids
also include crude oils downstream of the first
point of custody transfer. Organic liquids do
not include gasoline or other liquids used as
fuels, hazardous waste, waste water, ballast
water, or any other non-crude oil liquids with
annual average true vapor pressures less than
0.7 kilopascals (0.1 psia).
Organic liquids distribution operations are
carried out at storage terminals, refineries, crude pipeline stations, and various
manufacturing facilities. OLD-type operations include the combination of
activities and equipment used to store or transfer organic liquids into, out of, or
within a plant site regardless of the specific activity being performed. OLD-type
activities include the storage, transfer, blending, compounding, and packaging of
liquids.
Certain types of plants that have OLD-type operations are not subject to this rule and
include:
research and development facilities,
oil and natural gas production field facilities, and
natural gas transmission and storage facilities.
If you determine that you do not have any organic liquids, or that you do not distribute
organic liquids, you are not subject to the OLD NESHAP.
Key Points
The OLD NESHAP only
applies to major sources.
Organic liquids as defined
by the rule do not include
gasoline or other fiiels.
An affected source is the
collection of activities and
equipment used to distribute
organic liquids into, out of,
or within a major source
facility.
Distribution refers to the
transfer of organic liquids
into, out of, or within a plant
site regardless off the
specific activity being
performed.
Major source status of your
facility is determined based
on all HAP compounds; but
only 92 HAPs are used to
meet the HAP content
criteria in the definition of
organic liquid in §63.2406.
-------
Throughout this implementation tool, the words "affected source" are used. An affected
source is composed of:
all storage tanks storing organic liquids.
all transfer racks at which organic liquids are loaded into or unloaded out of
transport vehicles and/or containers.
all equipment leak components in organic liquids services that are associated
with: storage tanks, transfer racks, various types of pipelines and pipeline
transfers.
all transport vehicles while they are loading or unloading organic liquids at
transfer racks subject to Subpart EEEE.
all containers while they are loading or unloading organic liquids at transfer racks
subject to Subpart EEEE.
Figure 2.1 (a) helps you determine if you are subject to Subpart EEEE. Figure 2.1(b)
helps you determine if any of your emission sources are subject to Subpart EEEE. Figure
2.1(b) also steers you to the section within this implementation tool pertaining to the
emissions source of interest. Finally, Figure 2.1(c) helps you determine if your facility is
new/reconstructed or existing.

Key Terms:
1. Affected source, for the purposes of this part, means the collection of equipment,
activities, or both within a single contiguous area and under common control that is
included in a section 112(c) source category or subcategory for which a section 112(d)
standard or other relevant standard is established pursuant to section 112 of the Act. For
the purpose of OLD M ACT, the affected source is defined as the collection of activities
and equipment used to distribute organic liquids into, out of, or within a facility that is a
major source of HAP. The affected source is composed of: (1) All storage tanks storing
organic liquids. (2) All transfer racks at which organic liquids are loaded into or unloaded
out of transport vehicles and/or containers. (3) All equipment leak components in organic
liquids service that are associated with: (i) Storage tanks storing organic liquids; (ii)
Transfer racks loading or unloading organic liquids; (iii) Pipelines that transfer organic
liquids directly between two storage tanks that are subject to this subpart; (iv) Pipelines
that transfer organic liquids directly between a storage tank subject to this subpart and a
transfer rack subject to this subpart; and (v) Pipelines that transfer organic liquids directly
between two transfer racks that are subject to this subpart. (4) All transport vehicles while
they are loading or unloading organic liquids at transfer racks subject to this subpart. (5)
All containers while they are loading or unloading organic liquids at transfer racks
subject to this subpart (§63.2338 (b) (1 )-(5)).
2. Construction means the on-site fabrication, erection, or installation of an affected
source. Construction does not include the removal of all equipment comprising an
affected source from an existing location and reinstallation of such equipment at a new
location. The owner or operator of an existing affected source that is relocated may elect
not to reinstall minor ancillary equipment including, but not limited to, piping, ductwork,
and valves. However, removal and reinstallation of an affected source will be construed
as reconstruction if it satisfies the criteria for reconstruction as defined in this section.
The costs of replacing minor ancillary equipment must be considered in determining
whether the existing affected source is reconstructed.
3. Organic liquids means: 1) Any non-crude oil liquid or liquid mixture that contains 5
percent by weight or greater of the organic HAP as determined using the procedures
specified in §63.2354(c). 2) Any crude oils downstream of the first point of custody
transfer. 3) Organic liquids do not include the following: gasoline (including aviation
gasoline), kerosene (No. 1 distillate oil), diesel (No. 2 distillate oil), asphalt, and heavier
distillate oils and fuel oils. Organic liquids also do not include any fuel consumed or
dispensed on the plant site directly to users (such as fuels for fleet refueling or for
refueling marine vessels that support the operation of the plant), hazardous waste,
wastewater, ballast water, or any non-crude oil liquid with an annual average true vapor
pressure less than 0.7 kilopascals (0.1 psia).
4. Organic liquids distribution operations means the combination of activities and
equipment used to store or transfer organic liquids into, out of, or within a plant site
regardless of the specific activity being performed. Activities include, but are not limited
to, storage, transfer, blending, compounding, and packaging.
-------
5. In organic liquids service means that an equipment leak component contains or
contacts organic liquids having 5 percent by weight or greater of the organic HAP listed
in Table 1 to Subpart EEEE.
6. Research and Development Facility means a laboratory and/or pilot plant operation
whose primary purpose is to conduct research and development into new processes and
products, where the operations are under the close supervision of technically trained
personnel, and which are not engaged in the manufacture of products for commercial
sale, except in a de minimis manner.
7. Reconstruction means the replacement of components of an affected or a previously
nonaffected source to such an extent that: (1) The fixed capital cost of the new
components exceeds 50 percent of the fixed capital cost that would be required to
construct a comparable new source; and (2) It is technologically and economically
feasible for the reconstructed source to meet the relevant standard(s) established by the
Administrator (or a State) pursuant to section 112 of the Act. Upon reconstruction, an
affected source, or a stationary source that becomes an affected source, is subject to
relevant standards for new sources, including compliance dates, irrespective of any
change in emissions of hazardous air pollutants from that source.
-------
2.2 Applicability for Storage Tanks
At this point you have determined that you have a
facility that is subject to the OLD NESHAP, and that
you have a storage tank. Figure 2.2 allows you to
determine if your storage tank is part of an affected
source.
The following types of storage tanks are not part of the
affected source:
storage tanks that are subject to a different 40
CFR Part 63 NESHAP,
storage tanks that are "non-permanent," and
storage tanks that are used to conduct standard
maintenance activities, such as stormwater
management, liquid removal from tanks for
inspections and maintenance, or changeovers
to a different liquid stored in a storage tank.
Key Points
All storage tanks storing
organic liquids are subject
to the OLD NESHAP
unless specifically
excluded by the rale.
A storage tank is a
stationary unit that is
designed to hold a bulk
quantity of liquid. Storage
tanks excluded from the
rule include: units
permanently attached to
conveyances such as
trucks, trailers, rail cars,
barges, or ships; pressure
vessels; bottoms receivers;
surge control vessels;
vessels storing
wastewater; or reactor
vessels.
Floating roof storage tanks that are part of the OLD
NESHAP affected source but that are in compliance
with either 40 CFR 60, Subpart Kb, or 40 CFR Part
61, Subpart Y are considered to be in compliance with
the OLD NESHAP. Similarly, fixed roof storage tanks that are controlled with a closed
vent system and control device and that are in compliance with 40 CFR Part 60, subpart
Kb or 40 CFR Part 61, Subpart Y can remain in compliance with those subparts to
establish compliance with the OLD NESHAP.
Alternatively, if your storage tank is part of an OLD affected source, but is subject to
control under the above mentioned subparts, you can comply with the storage tank
standards that are included in Table 2 of the OLD NESHAP.

-------
Key Terms
1. Storage tank means a stationary unit that is constructed primarily of nonearthen
materials (such as wood, concrete, steel, or reinforced plastic) that provide structural
support and is designed to hold a bulk quantity of liquid. Storage tanks do not include
units permanently attached to conveyances such as trucks, trailers, rail cars, barges, or
ships, pressure vessels designed to operate in excess of 204.9 kilopascals and without
emissions to the atmosphere, bottom receivers, surge control vessels, vessels storing
wastewater, or reactor vessels associated with a manufacturing process unit.
2. Closed vent system means a system that is not open to the atmosphere and is
composed of piping, ductwork, connections, and, if necessary, flow-inducing devices that
transport gas or vapors from an emission point to a control device. This system does not
include the vapor collection system that is part of some transport vehicles or the loading
arm or hose that is used for vapor return. For transfer racks, the closed vent system
begins at, and includes, the first block valve on the downstream side of the loading arm or
hose used to convey displaced vapors.
3. Control device means any combustion device, recovery device, recapture device, or
any combination of these devices used to comply with this subpart. Such equipment or
devices include, but are not limited to, absorbers, adsorbers, condensers, and combustion
devices. Primary condensers, steam strippers, and fuel gas systems are not considered
control devices.
-------
-------
2.3 Emission Limits, Operating Limits, and Work Practice Standards for Storage
Tanks
Whether a storage tank must be controlled and to what
extent depends on the size of the tank and the vapor
pressure of the organic liquid stored within the tank. In
addition, control requirements vary depending on
whether the tank is at a new/reconstructed or existing
affected source.
KEY POINT
Even though your storage
tank may be subject to the
OLD NESHAP, it may not
require control.
Facilities to which the standards for storage tanks apply
have various options for achieving compliance with the emission limits presented in
Table 2. Facilities may:
reduce emissions of total organic HAP by at least 95 weight-percent, or, as an
option, to an exhaust concentration less than or equal to 20 ppmv,
vent emissions through a closed vent system to any combination of control
devices meeting the applicable requirements of 40 CFR part 63, subpart SS,
comply with the work practice standards specified in Table 4, items 1 .a, 1 .b, or
1 .c for tanks storing liquids described in that table.
Items 1 .a, 1 .b, and 1 .c of Table are specific to work practice standards and offer a facility
three options.
The first option allows you to comply with the requirements of 40 CFR 63,
Subpart WW (control level 2).
The second option allows you to comply with the requirements of 40 CFR 63,
Subpart SS (§63.984) for routing emissions to a fuel gas system or back to a
process.
The third option allows you to comply with the requirements of §63.2346(a)(4)
for vapor balancing emissions to the transport vehicle from which the storage
tanks is filled.
The OLD NESHAP also addresses compliance requirements you have if your facility is
subject to both Subpart EEEE and another subpart. Specifically, §63.2396(a) provides
information on complying with Subpart EEEE and other subparts for fixed and floating
roof storage tanks. For example, you are in compliance with Subpart EEEE if you have
floating roof storage tank that is in compliance with the provisions of 40 CFR part 60,
Subpart Kb, or 40 CFR 61, Subpart Y, except that records must be kept for 5 years rather
than 2 years for storage tanks that are assigned to the OLD affected source. Similarly, if
you have a fixed roof storage tank that is in compliance with the above-referenced
subparts, you are in compliance with Subpart EEEE except that you must comply with
the monitoring, recordkeeping, and reporting requirements of Subpart EEEE. Finally, if
you have a storage tank that is assigned to the OLD affected source and is subject to
control under 40 CFR 60, Subpart Kb, or 40 CFR 61, Subpart Y, you can chose to

2.4 Applicability for Containers
Containers are portable storage vessels in which liquids can
be stored and transported. Typically, they are plastic units
that are oftentimes surrounded by metal framework. A tote
is synonymous with containers. Containers are specifically
referenced in 40 CFR 63.2338, and the rule states that they
are subject to the OLD NESHAP while they are being
loaded or unloaded with organic liquids at transfer racks at
new or reconstructed facilities.
Containers are specifically excluded from the affected
source if:
they are part of an affected source under another 40
CFR part 63 NESHAP,
they are used in special situation distribution loading/unloading operations, and
they are used to conduct maintenance activities, such as stormwater management,
liquid removal from tanks for inspections and maintenance, or changeovers to a
different liquid stored in a storage tank.
Figure 2.4 is designed to help you determine if your container is subject to the OLD
NF.SHAP.
Key Points
AH containers, unless
specifically excluded by the
rule, are subject to the OLD
NESHAP while they are
loading/unloading at transfer
racks.
Containers specifically
include drums and portable
cargo containers called
"totes."

1. Container means a portable unit in which a material can be stored, transported,
treated, disposed of, or otherwise handled. Examples of containers include, but are not
limited to, drums and portable cargo containers known as "portable tanks" or "totes."
-------
2.5 Emission Limits, Operating Limits, and Work Practice Standards for
Containers
All containers at affected sources are subject to the OLD
NESHAP unless they are specifically excluded. Only
containers having volumes equal to or greater than 55 gallons
that are filled by transfer racks at new/reconstructed facilities
require control. You can control container filling by
complying with §63.924 through §63.927 of 40 CFR 63
Subpart PP (National Emission Standards for Containers,
Container Level 3 Controls) or by complying with the work
practice standards specified in Item 3.a of Table 4 to Subpart EEEE.

Only containers
having capacities
>55 gallons at new
facilities require
control.

-------
Key Points
By definition, a transfer
rack only loads/unloads
organic liquids into
transport vehicles or
containers.
* Transport vehicle
means a cargo tank or
tank car.
2.6 Applicability for Transfer Racks
Subpart EEEE states that all transfer racks at which
organic liquids are loaded into or unloaded out of
transport vehicles and/or containers are subject to the
rule, except as follows:
transfer racks that are part of an affected source
under another 40 CFR Part 63 NESHAP,
non-permanent transfer racks when used in
special situation distribution loading and
unloading operations, and,
transfer racks that are used to conduct
maintenance activities, such as storm water management, liquid removal from
tanks for inspections and maintenance, or changeovers to a different liquid stored
in a storage tank.
The OLD NESHAP also addresses compliance requirements you have if your facility is
subject to both Subpart EEEE and another subpart. Specifically, §63.2396(b) states that
if you have transfer racks that are subject to 40 CFR Part 61, subpart BB (National
Emission Standard for Hazardous Air Pollutants for Benzene Emissions from Benzene
Transfer Operations), you are required to meet all the requirements of Subpart EEEE
while the transfer rack is in OLD operation during the loading of organic liquids.
The flowchart in Figure 2.6 assists you in determining the applicability of the transfer
rack standards in Subpart EEEE to your facility.

Key Term
1. Transfer rack means a single system used to load organic liquids into, or unload
organic liquids out of, transport vehicles or containers. It includes all loading or
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.
2. Cargo tank means a liquid-carrying tank permanently attached and forming an
integral part of a motor vehicle or truck trailer. This term also refers to the entire cargo
tank motor vehicle or trailer. For the purpose of this subpart, vacuum trucks used
exclusively for maintenance or spill response are not considered cargo tanks.
3. Tank car means a car designed to carry liquid freight by rail, and including a
permanently attached tank.

2.7 Emission Limits, Operating Limits, and Work Practice Standards for Transfer
Racks
This section only addresses transfer rack loading and
unloading of transport vehicles. Transfer rack loading of
containers is addressed in Sections 2.4 and 2.5. The
flowcharts presented in this section provide important
decision points and help you navigate to the control
requirements presented in Subpart EEEE. The
determination of which transfer rack is to be controlled
and to what extent depends on the following criteria:
Key Points
* Transfer racks require controls
if they meet certain throughput
thresholds.
The HAP weight percentage of
the organic liquids is different
for new/reconstructed or
existing facilities.
Only transfer racks loading
organic liquid are subject to
control.

an organic liquid (only transfer racks are
controlled),
the annual throughput of all transfer racks at a
facility, and
whether a facility is new/reconstructed, or an existing facility.
Facilities to which the standards for transfer racks apply have various options for
achieving compliance with the emissions limits presented in Table 2. Facilities may:
reduce emissions of total organic HAP from the loading of organic liquids either
by venting the emissions that occur during loading through a closed vent system
to any combination of control devices meeting the applicable requirements of 40
CFR 63 Subpart SS (National Emission Standards for Closed Vent Systems,
Control Devices, Recovery Devices and Routing to a Fuel Gas System or a
Process) while achieving 98 weight percent HAP reduction, or,
reduce emissions of total organic HAP using any combination of control devices
to an exhaust concentration less than or equal to 20 ppmv on a dry basis corrected
for 3 percent oxygen for combustion control devices using supplemental air, or,
comply with the work practice standards specified in Item 3 of Table 4.
Item 3 of Table 4 is specific to work practice standards and offers a facility two options:
The first option (Table 7, Items 3.b.i) is for vapor balancing systems and requires
that vapors displaced from the loading of transport vehicles be returned to the
storage tank from which the liquid originated, or that vapors be returned to
another storage tank connected by a common header.
The second option allows a facility to comply with the requirements of §63.984
(Fuel gas systems and processes to which storage vessel, transfer rack, or
equipment leak regulated material emissions are routed).

Key Points
Equipment leak
components are
limited to pumps,
valves, and sampling
connection systems.
Equipment must be in
OLD service.
Equipment must be
associated with
storage tanks, transfer
racks or pipelines.
2.8 Applicability for Equipment Leak Components
The OLD rule applies to three specific types of equipment
leak components: valves (except relief valves and check
valves), pumps, and sampling connection systems. To be
subject to OLD, the component must be in OLD service
and must be associated with one of the following:
storage tanks storing organic liquids,
transfer racks loading or unloading organic
liquids,
pipelines that transfer organic liquids directly
between two storage tanks that are subject to the
OLD NESHAP,
pipelines that transfer organic liquids directly
between a storage tank and a transfer rack subject
to the OLD NESHAP, or
pipelines that transfer organic liquids directly between two transfer racks subject
to the OLD NESHAP.
Similar to storage tanks, containers, and transfer racks, the OLD NESHAP does not apply
to certain equipment leak components as follows:
equipment leak components that are part of an affected source under another 40
CFR Part 63 NESHAP,
equipment leak components when used in special situation distribution loading
and unloading operations, and
equipment leak components when used to conduct maintenance activities, such as
stormwater management, liquid removal from tanks for inspections and
maintenance, or changeovers to a different liquid stored in a storage tank.
Otherwise, equipment leak components not specifically excluded may be subject to
control by the OLD NESHAP and detailed information as well as a flowchart is provided
in Section 2.10.
Figure 2.8 helps you determine the applicability for equipment leak components.

Key Terms
1. Equipment leak component means each pump, valve, and sampling connection
systems used in organic liquids service at an OLD operation. Valve types include
control, globe, gate, plug, and ball. Relief and check valves are excluded.
2. In organic liquids service means that an equipment leak component contains or
contacts organic liquids having 5 percent by weight or greater of the organic HAP listed
in Table 1 to Subpart EEEE.
29
-------
-------
2.9 Leak Detection and Repair Requirements for Equipment Leaks
Equipment leak components subject to OLD are required
to be controlled through leak detection and repair
programs (LDAR). The OLD NESHAP incorporates these
by reference. The requirements only apply if your
affected source has at least one storage tank or one
transfer rack that meets the applicability criteria for
control in Table 2 of the OLD NESHAP. Additionally,
the requirements only apply to pumps, valves, and
sampling connection systems that operate in OLD service
for at least 300 hours per year. If you meet the criteria
mentioned above, you must comply with the applicable
requirements under:
Key Points
For LDAR to apply,
equipment must be in
OLD service for at least
300 hr/yr.
If one storage tank or
transfer rack is subject
to control, all
equipment leak
components are subject
to LDAR.
The owner/operator
may elect which of 3
subparts to comply
with.
40 CFR 63, Subpart TT - NESHAP for
Equipment Leaks, Control Level 1,
40 CFR 63, Subpart UU - NESHAP for
Equipment Leaks, Control Level 2, or
40 CFR 63, Subpart H - NESHAP for Organic HAP for Equipment Leaks.
Of importance is that the owner/operator can choose the subpart (from the list above)
under which LDAR will be conducted. In addition, pumps, valves, and sampling
connection systems that are insulated to provide protection against persistent subfreezing
temperatures are subject to the difficult to monitor provisions in the applicable subpart
selected by the facility.
The OLD NESHAP also has provisions in §63.2396(c) for equipment leak components
that are subject to other rules. If your equipment leak components are subject to a 40
CFR 60 Subpart. and the equipment is in OLD operation and in organic liquids service,
then you must comply with the provisions of both rules. If you have pumps, valves, and
sampling connection systems subject to 40 CFR 63 Subpart GGG (NESHAP for
Pharmaceutical Production), and the equipment is in OLD operation and service, you can
elect to comply with the OLD NESHAP provisions.
Finally, there are provisions within Subpart EEEE for dealing with overlapping
regulations for monitoring, recordkeeping, and reporting requirements. This provision
pertains to equipment components associated with a transfer rack subject to the OLD
NLSHAP that only unloads organic liquids directly to or via pipeline to a non-tank
process unit component or to a storage tank subject to another 40 CFR 63 subpart. In this
case, if you are applying the applicable recordkeeping and reporting requirement of the
different subpart, you must also be in compliance with the recordkeeping and reporting
requirements of the OLD NESHAP. If the recordkeeping and reporting satisfies the
requirements of this subpart, you may elect to continue to comply with the recordkeeping
and reporting requirements of the other subpart. However, you must identify the other
subpart being complied with in the Notification of Compliance Status.

2.10 Monitoring of Equipment Components in Gas-Vapor Service and/or Light
Liquid Service under Subpart TT, UU, or Subpart H when Using Vapor Balancing
The equipment leak component provisions in the OLD
NESHAP only apply to valves, pumps, and sampling
connection systems. Nevertheless, if you operate a vapor
balancing system for a transfer rack or a storage tank
subject to the emission limits presented in Table 2 to
Subpart EEEE, you are required to monitor each potential
source of vapor leakage on a quarterly basis.
The leak definition for equipment used for vapor balancing
is 500 ppmv. If a leak is detected, it must be repaired in
accordance to the provisions of the LDAR NESHAP that
was selected for your facility. As was stated in Section
2.9, you can comply with:
40 CFR 63 Subpart H, NESHAP for Organic HAP
for Equipment Leaks,
40 CFR 63 Subpart TT, NESHAP for Equipment
LeaksControl Level 1, or
40 CFR 63 Subpart UU, NESHAP for Equipment Leaks
Key Points
When using vapor
balancing, valves,
pumps, and sampling
connections are not
the only equipment
components that need
to be monitored.
Each potential source
of vapor leakage must
be monitored,
Pressure relief devices
are subject separately
through §63.2346
The leak definition is
500 ppmv
-Control Level 2.
The rule also states that if you do not load a transport vehicle or fill a container during a
quarter you are not required to monitor the vapor balancing system for leaks.

2.11 Requirements for Affected Equipment Not Requiring Control
You may have emission sources subject to Subpart
EEEE but for which no control is required. Such
sources, however, may still have certain notification,
recordkeeping, and reporting requirements. Section
63.2343 identifies all notification, recordkeeping, and
reporting requirements.
Notification, recordkeeping, and reporting
requirements are required for two sets of equipment:
storage tanks with capacities > 5,000 gallons
that are not subject to control under Subpart
EEEE, and
transfer racks that load organic liquids that are
not subject to control under Subpart EEEE.
Any equipment that does not require control and that
does not fall within one of the two categories listed
above has no additional notification, recordkeeping or
reporting requirements. A brief summary of the
notification, reporting, and recordkeeping requirements
for the equipment listed above is provided below. It is
important to note that you are required to submit
information in either the Notification of Compliance
Status or your first and subsequent compliance reports.
The order in which these are submitted is important
and will determine what information you will have to
report:
Key Points
If you have a storage tank
or transfer rack which
requires no control (i.e.
below size cut off or only
unloads organic liquid),
then you must maintain up-
to-date documentation
verifying these sources are
not required to be
controlled.
If you have a storage tank
with a capacity > 5,000
gallons that is not subject
to control, you are required
to maintain records
documenting the annual
average true vapor pressure
of the organic HAP stored
in the tank.
If you have a transfer rack
that is not subject to
control under Subpart
EEEE, you must maintain
records detailing the total
actual annual facility-level
organic liquid loading
volume through transfer
racks.
for storage tanks with capacities > 5,000 gallons that are not subject to control
under Subpart EEEE, you are required to submit information on the tanks and
your facility in the compliance report or in the Notification of Compliance Status,
and
for transfer racks that load organic liquids but are not subject to control under
Subpart EEEE, you are required to submit information on your transfer racks and
your facility in your compliance report or your Notification of Compliance Status.
In addition, events may occur that would trigger subsequent compliance reports. These
events are:
when a storage tank or transfer rack becomes subject to control under Subpart
EEEE,
when any storage tank > 5,000 gallons becomes part of the affected source but is
not subject to control,
34
-------
when a transfer rack that loads organic liquids becomes part of the affected
source, and
when reporting requirements of §63.2386 (c)(l)-(3) change.
The notification, recordkeeping, and reporting requirements are presented in Table
2.11.1.
For storage tanks with capacities < 5,000 gallons and transfer racks that only unload
organic liquids, you are required to maintain up-to-date documentation that verifies that
these equipment are not required to be controlled.

2.12 Compliance Timeline
This section presents two timelines: compliance dates for
emission limits, operating limits, work practice standards,
and compliance dates for notification, recordkeeping, and
reporting.
The compliance timeline for emissions limits, operating
limits, and work practice standards varies depending on
whether you have a new/reconstructed, or existing affected
source. The flowcharts in Figures 2.12(a) and 2.12(b)
provide information on the various dates and conditions for
new/reconstructed and existing facilities.
Key Points
You can only submit
one request for a
compliance extension.
You arc required to
submit applicable
reports from 40 CFR
63 Subparts A, H, SS,
TT, UU, WW.
There are also requirements and timelines for the submission of compliance reports and
notifications of compliance status. These requirements exist for both equipment not
requiring control (refer to Section 2.11), and controlled equipment. Depending on the
order in which the reports are submitted, there are also requirements for the information
that must be submitted in the reports. Subpart SS is incorporated into Subpart EEEE by
reference. Subpart EEEE requires that you submit all applicable reports and notifications
from Subpart SS. Table 2.12 provides you with the notification and reporting
requirements, their due dates, and a crosswalk to the applicable Subpart SS requirements.
If you currently operate an area source, and you increase your emissions or potential to
emit to the point that you become a major source of HAP emissions and an existing
affected source subject to Subpart EEEE, you have 3 years to come into compliance with
this subpart once you trigger the major source threshold.

Key Terms
1. New affected source means the collection of equipment, activities, or both within a
single contiguous area and under common control that is included in a section 112(c)
source category or subcategory that is subject to a section 112(d) or other relevant
standard for new sources. This definition of "new affected source," and the criteria to be
utilized in implementing it, shall apply to each section 112(d) standard for which the
initial proposed rule is signed by the Administrator after June 30, 2002. Each relevant
standard will define the term "new affected source," which will be the same as the
"affected source" unless a different collection is warranted based on consideration of
factors including:
(1) Emission reduction impacts of controlling individual sources versus groups of
sources;
(2) Cost effectiveness of controlling individual .equipment;
(3) Flexibility to accommodate common control strategies;
(4) Cost/benefits of emissions averaging;
(5) Incentives for pollution prevention;
(6) Feasibility and cost of controlling processes that share common equipment (e.g.,
product recovery devices);
(7) Feasibility and cost of monitoring; and
(8) Other relevant factors.
2. New source means any affected source the construction or reconstruction of which is
commenced after the Administrator first proposes a relevant emission standard under this
part establishing an emission standard applicable to such source.
3. Existing source means any affected source that is not a new source.

2.13 Monitoring and Demonstrating Continuous Compliance
Key Points
High throughput
transfer racks have
their own set of
continuous compliance
requirements with
operating limits.
With exceptions, you
must demonstrate
continuous compliance
even during periods of
startup, shutdown, and
malfunction.
Subpart EEEE has continuous compliance requirements for
storage tanks, transfer racks, and equipment leaks. The
continuous compliance requirements are addressed in the rule
in §63.2366, §63.2374, and §63.2378. The continuous
compliance requirements are presented in Tables 8, 9, and 10
of Subpart EEEE. Table 8 provides continuous compliance
requirements for emission limits. Table 9 provides
continuous compliance requirements for operating limits, and
Table 10 provides continuous compliance requirements for
work practices.
Storage tanks have continuous compliance requirements for
emission limits and work practices. Transfer racks have
continuous compliance requirements for emission limits,
operating limits (in the case of high throughput transfer
racks), and work practices. Finally, equipment leaks have continuous compliance
requirements for work practices only.
Tables 8-10 reference three other 40 CFR 63 subparts. 40 CFR §63.1 - §63.16 are part of
Subpart A, which are the General Provisions. Table 9 specifically references §63.11.
This section provides requirements for control devices. 40 CFR §63.980 - §63.999 are
part of Subpart SS - the NESHAP for closed vent systems, control devices, recovery
devices, and routing to a fuel gas system or a process. 40 CFR §63.1060 - §63.1067 are
part of Subpart WW - the NESHAP for storage vessels (tanks), control level 2. You will

3.0 QUESTIONS AND ANSWERS
The following Questions and Answers are provided for guidance purposes only and are
not final determinations of applicability for any particular source, nor are they official
regulatory interpretations. The Questions and Answers have been grouped by subject
area.
A. Compliance Timeline
Ql: What is the due date of the first compliance report? The rule states at
§63.2386(b)(l)(ii) that it is to be postmarked no later than July 31 or January 31,
whichever date follows the end of the first calendar half after the compliance date.
Al: The due date of the first compliance report is no later than July 31, 2007.
Q2: Section 63.2386(b)(l) of the OLD rule requires submittal of the first compliance
report on July 31 covering the period of February 5, 2007 through June 30, 2007. Section
63.2386(b)(3) allows a source to submit their compliance reports on their Title V
schedule. For example, assume the Title V reporting schedule is March 31s1 and
September 30lh.
May the source wait until September 30, 2007 to submit its first OLD MACT
compliance report, OR
Must it submit the first compliance by the July 31 date and then resubmit the
second one early on September 30th in order to get on its Title V schedule?
A2: Section 63.2386(b)(3) allows you to use the Title V submittal date in lieu of the
OLD submittal date for both the initial and subsequent compliance reports. Therefore,
the source may wait until September 30 to submit its initial compliance report.
B. Applicability
Q3: Can a facility calculate an average of all available HAP concentrations data from
sample analysis or process knowledge to determine whether non-crude liquid or liquid
mixtures contain 5 percent by weight or greater of the organic HAP listed in Table 1 to
Subpart EEEE? Can this HAP determination be based on an annual average according to
§63.2354(c)?
A3: Yes. The owner/operator of a facility is free to use whichever source of
information he/she feels is appropriate to make the HAP determination. However,
records documenting the process and sources of data should be kept in case you are
audited. If for example, you have average HAP concentration data, you are free to
calculate an average HAP concentration value, but you are required to maintain
documentation of the data and the process in which you calculated the average HAP
concentration data.
53
-------
Q4: A facility uses toluene as a fuel to produce an inorganic chemical. Does the fact
that the toluene is used as fuel mean that it does not meet the definition of organic liquid
at §63.2406?
A4: No. The OLD rule applies to the storage and transfer of toluene used as fuel. The
exemption for a fuel only applies to a fuel that is a "common" fuels and not to other
organic liquids that could be used as fuel because of their heating value. Gasoline was
excluded outright from the OLD rule, and kerosene, diesel, asphalt, and the heavier
distillates were excluded because their respective vapor pressures were below 0.1 psia.
The EPA always intended that pure HAPs, such as toluene, which meet the vapor
pressure cutoff, would be subject to the rule.
Q5: What is the applicability of the OLD rule to storage tanks at a tank farm located at
Hazardous Organic NESHAP (HON) facility?
AS: The OLD rule would potentially apply to storage tanks located at a tank farm
where there is an intervening storage tank that can be assigned to the chemical
manufacturing process unit (CMPU) at the HON facility. For purposes of the HON, an
intervening storage vessel means a storage vessel connected by hard-piping to the CMPU
and to the storage vessel in the tank farm so that product (or raw material) entering or
leaving the chemical manufacturing process unit flows into (or from) the intervening
storage vessel and does not flow directly into (or from) the storage vessel in the tank
farm. Where there is an intervening storage vessel, the boundary of the CMPU would
end at that intervening storage vessel (and any associated transfer operations and other
equipment) and would exclude the tank farm storage vessel. Therefore, the storage tank
at the tank farm would not be part of the HON affected source and therefore should be
evaluated for potential applicability under the OLD rule.
Q6: A tank at a tank farm sometimes receives product directly from a chemical
manufacturing process unit (CMPU) subject to the Hazardous Organic National
Emissions Standard for Hazardous Air Pollutants (HON) and sometime receives product
from an intervening tank or directly from another CMPU. How do you determine
applicability of either the HON or OLD to that tank?
A6: The preamble to the proposed amendments for the "intervening tank" language in
the HON, at 61 FR 43700 (August 26, 2006), clarifies this by specifying three rules for
assigning a storage vessel to a CMPU, as follows:
1. A storage vessel at a tank farm is considered to be part of
the CMPU ONLY if the CMPU does not have an
intervening storage vessel.
2. If two or more CMPU's use the tank farm tank, and
NONE of them have an intervening storage vessel, then
you assign the storage tank at the tank farm to the
appropriate CMPU per the concepts of predominant use at
63.100(g)(2).
54
-------
3. If only one CMPU, of the two or more that use the tank
farm tank, has no intervening storage tank, then the tank
farm tank is assigned to that one CMPU with no
intervening storage tank.
The situation presented above is described by #3. In that case, the tank farm tank would
be assigned to the CMPU which directly feeds it, and OLD would not apply.
Q7: How do you determine applicability under the gasoline distribution MACT (GD
MACT) and/or the OLD rule at an independent terminal? The terminal stores and loads
both gasoline and non-gasoline organic liquids as well as other products. Vessels and
equipment change service over time depending on customer demand. A storage vessel
can change service from organic liquid service to gasoline service.
A7: The facility would have to be in compliance with the GD MACT when storing
gasoline and meeting the applicability of the GD MACT, and in compliance with the
OLD MACT when storing organic liquids and meeting the applicability of the OLD rule.
Neither rule has procedures for determining primary use for flexible use storage tanks.
Q8: A printing facility transfers 5,000 gallons/day of recovered toluene from storage
tanks into tank trucks. There is no control at the loading rack so the displaced emissions
from the tank trucks are released into the atmosphere. They also receive ink containing
toluene solvent that they store and mix in storage tanks with capacities of 10,000 and
12,000 gallons. The loading rack, storage and tank trucks are affiliated with the printing
operation but are not part of the affected facility under that rule. Would the loading rack
and the tanks be subject to OLD regulations?
A8: Yes. There is no exemption for affiliated operations under the OLD rule for
subparts which do not include the affiliated operations as part of the affected source.
Q9: Would sources subject to the MON rule be subject to OLD during the interim
period between the compliance date of the OLD rule (February 7, 2007) and the
compliance date of the MON rule, which was extended until May 10, 2008?
A9: No. Affected equipment regulated under the MON requirements would not be
subject to the OLD rule during the interim between the OLD and MON rule compliance
dates. Storage tanks, transfer racks, transport vehicles, containers, and equipment leak
components that are part of a MON affected source would not be subject to OLD, per
§63.2338(c)(l). The fact that the compliance date of the MON is after the compliance
date of OLD does not alter this.
C. Initial Compliance Demonstration
Q10: Can a facility conduct a design evaluation for a nonflare control device per
§63.985(b)(l)(i) to satisfy initial compliance with the emission limit requirements of
Subpart EEEE for a high throughput transfer rack?
55
-------
A10: No. Per §63.2354(b)(l), a performance test is required and the design evaluation
requirements of §63.985 are not referenced, therefore they are not allowed. The
applicable sections to non-flare control devices are §63.7(e), §63.988(b), §63.990(b), or
§63.995(b). These sections provide the requirements for conducting performance tests,
and the specific procedures for conducting these are provided in §63.997(e).
Qll: Can a facility request a compliance extension for circumstances other than those
described in §63.2342(b)(3)(ii)?
All: Yes. The Administrator may also grant extension of compliance under 40 CFR
Subpart A for existing sources who need additional time for the installation of controls.
Section 63.6(i) provides the requirements for requesting compliance extensions.
D. Continuous Compliance
Q12: How do you demonstrate continuous compliance for a facility that fills transport
vehicles or containers from a storage tank using a vapor balancing system?
A12: For vapor balancing systems, there are two places in subpart EEEE that identify
compliance requirements - Table 10 and §63.2346(a)(4). Item 6.b.i in Table 10 provides
the specific continuous compliance requirement for a storage tank using a vapor
balancing system and references Table 4, item 4 for the quarterly monitoring of "each
potential source of vapor leakage in the system". Paragraph (a)(4)(v) of §63.2346
separately identifies leak detection and repair (LDAR) requirements for pressure relief
devices used in vapor balancing systems.
The phrase "each potential source of vapor leakage" is intended to apply to any and all
equipment in the vapor balancing system that may leak, including but not limited to
equipment as defined by subpart EEEE, but not pressure relief devices. For all such
equipment, the owner or operator must apply the applicable provisions found in the
equipment leak standard, selected by the owner or operator, to comply with the
equipment leak components. If the vapor balancing system has a pressure relief valve,
however, the owner or operator would comply separately with the LDAR provisions for
pressure relief valves found in §63.2346(a)(4)(v).
Q13: What are the requirements concerning Notification of Compliance Status and
Subsequent Compliance reports for storage tanks not subject to control based on the
criteria specified in Subpart EEEE?
A13: The specific requirements for storage tanks not requiring control are presented in
§63.2343(a) and (b) ("What are my requirements for emission sources not requiring
control?"). Storage tanks that never require control based on size are subject only to
maintaining readily accessible, up to date documentation of such and have no further
recordkeeping, notification or reporting requirements. For storage tanks which do not
require control based on vapor pressure cutoffs, §63.2343(b)(l)(i) requires you to submit
the certain information in §63.2386:
56
-------
(c)( 1) - company name and address,
(c)(2) - statement by a responsible official, including the
official's name, title, and signature, certifying that, based
on information and belief formed after reasonable inquiry,
the statements and information in the report are true,
accurate, and complete,
(c)(3) - date of report and beginning and ending dates of
the reporting period, and
(10)(i) - a listing of tanks greater than or equal to 18.9 m3
(5,0000 gallons) that are part of the affected source but are
not subject to any of the emission limitations, operating
limits, or work practice standards of this subpart.
This information must be submitted in either the Notification of Compliance Status or in
the first Compliance report, whichever comes first. Further information on special
conditions regarding the submission of the Notification of Compliance Status and
Compliance reports, including subsequent compliance reports, is presented in
§63.2343(b)(l) through (2).
Q14: What is required for control devices controlling emissions from storage tanks or
low throughput transfer racks, if the owner or operator elects pursuant to §63.2346(e) to
comply with the operating limits in Table 3 for high throughput transfer racks?
A14: You can comply with the appropriate operating limit in Table 3 or, if a type of
control device other than one listed under Table 3 is utilized, then a monitoring plan is
required per Item 8 in Table 3.
K. Storage Tanks
QI5: A storage tank is subject to OLD but is not subject to control, based on the vapor
pressure of the stored liquid. It is associated with a loading rack that is subject to OLD
and subject to control, and intends to meet the transfer rack standard through vapor
balancing. C'an the transfer rack vapor balance to the uncontrolled storage tank?
A15: No. The storage tank to which the transfer rack vapor balances must be
controlled to ensure that there are no emissions losses. §63.2346(a)(4)(iv) specifically
states that no pressure relief devices on the storage tank shall be open during loading or
as a result of diurnal temperature changes during vapor balancing.
Q16: A compressed gas, which is a Table 1 organic HAP, is offloaded from railcars
using a pipeline and compressor system into a pressurized tank at an existing source. The
compressed gas remains in the gaseous state throughout the transfer. The tank is
designed to operate in excess of 204.9 kilopascals and without emissions to the
atmosphere. Is there any applicability to OLD?
A16: No. A compressed gases is not subject to Subpart EEEE because it does not meet
the definition of "organic liquid." If the compressed gas were transferred in the liquid
57
-------
state, then the transfer rack unloading the organic liquid would be subject to OLD but
would have no control requirements unless it met the criteria of item 7 or 8 of Table 2. If
the tank was designed to operate in excess of 204.9 kilopascals and without emissions to
the atmosphere, then it would not be a storage tank according to §63.2406.
Q17: Facilities subject to the OLD rule that have internal floating roof tanks complying
with Subpart WW (control level 2) may periodically land the floating roof on its support
legs, e.g., because of usage, to accommodate change of service, or to facilitate emptying
and degassing for roof and seal inspections or other maintenance. When the floating roof
is landed, the process of filling to the point of re-floating the floating roof must be
continuous and performed as soon as practical per §63.1063(b)(2). Would any of these
landings constitute startup and shutdown activities? If so, would the fact that the
requirements of §63.1063(b)(2) were met mean that there were no exceedances of the
relevant standard?
A17: Landing a floating roof in order to change the service of the tank or to empty and
degas the tank for roof and seal inspections or other maintenance are activities that would
constitute startup and shutdown. However, landings caused by lowering of the tank level
due to usage would not by definition be startup or shutdown.
Section 40 CFR 63.10(d)(5)(i) requires the submission of a startup, shutdown, and
malfunction (SSM) report that includes information about startups and shutdowns that
caused the source to exceed "any applicable emission limitation in the relevant emission
standards".
"Relevant standard" is further defined in 63.2 as follows:
Relevant standard.meam:
(1) An emission standard;
(2) An alternative emission standard;
(3) An alternative emission limitation; or
(4) An equivalent emission limitation established pursuant
to section 112 of the Act that applies to the collection of
equipment, activities, or both regulated by such standard or
limitation. A relevant standard may include or consist of a
design, equipment, work practice, or operational
requirement, or other measure, process, method, system, or
technique (including prohibition of emissions) that the
Administrator (or a State) establishes for new or existing
sources to which such standard or limitation applies. Every
relevant standard established pursuant to section 112 of the
Act includes subpart A of this part, as provided by
§63.1(a)(4), and all applicable appendices of this part or of
other parts of this chapter that are referenced in that
standard.
58
-------
If you are in compliance with §63.1063(b)(2), then you would be meeting the work
practice standard, which in this case is the relevant standard and would not be required to
submit a SSM report. If you are not in compliance with §63.1063(b)(2), then you would
be exceeding the applicable emission limitation in the relevant standard and would be
required to submit a SSM report.
In addition, a landing caused by lowering of the tank level due to usage would not
constitute an exceedance so long as the requirements of §63.1063(b)(2) are met.
F. Transfer Racks
Q18: There are many small volume transfers at refineries. One example is methanol
which is used for analytical tests. In this case, a tote is filled from a truck using piping,
valves and meters. The tote is then used to fill a pail by gravity drain. The pail is then
used to fill beakers in a laboratory, again by gravity. Which of these transfers would be
considered transfer rack transfers?
A18: By definition, a transfer rack is a system that transfers liquids into or out of
transport vehicles or containers. Therefore, the transfers from the truck to the tote using
piping, valves, and meters would be considered a transfer rack transfer; the transfer from
the tote to the pail would not and the pail to the beakers by gravity fill would not.
Q19: Would pumping any organic liquid out of or into a container or tote need to be
considered under the transfer rack provisions? If a drum is refilled by a tote using gravity
drain, does this constitute a transfer rack?
A19: Yes. Based on the definition of transfer rack, you would have to consider the
pumping of any organic liquid out of or into a container. A drum loading rack is
considered to be a loading rack. Filling a drum from a tote using gravity feed would not
be considered a transfer rack as this does not entail or require a system of loading arms,
pumps, meters, shutoff valves, relief valves, etc.
Q20: A facility pumps liquid directly from a tote to a reactor vessel. Is this activity
considered to be a transfer rack under Subpart EEEE? Would it make a difference if the
transfer was done through a hose rather than a pipe?
A20: Yes. If a facility pumps liquids from a tote to a day tank that is attached to the
process, and the day tank is not subject to a different 40 CFR 63 NESHAP, then this
operation would be considered to be a transfer rack under Subpart EEEE, if it otherwise
met the definition of transfer rack at §63.2406. Finally, it makes no difference if the
filling is done through a hose rather than a pipe.
Q21: Would loading/unloading of organic liquids via a tanker truck using a transfer
pump located on the truck and no other equipment other than hoses be considered a
transfer rack? Would it make a difference if the transfer pump was secured at the
facility?
59
-------
A21: Yes, this would be considered a transfer rack. It makes no difference if the pump
is located on the truck, or if it is secured at the facility.
Q22: What would trigger "new" transfer rack requirements under the OLD MACT at an
existing facility? Would reconstruction of the affected source trigger applicability of
items 9-10 in Table 2 or are only transfer racks at new (i.e. greenfield) affected sources
subject to items 9-10?
A22: Facility reconstruction would trigger the new source requirements for the affected
facility, including transfer racks. "Reconstruction" is defined as the replacement of
components that cost more than 50 percent of the cost of constructing a new unit or
source like the one being rebuilt. Both greenfield and reconstructed sources are subject
to the new source requirements in Table 2 at items 9-10. The addition of a transfer rack
that does not trigger reconstruction would not trigger new transfer rack requirements.
Q23: An OLD terminal proposes to meet 40 CFR 63 Subpart EEEE by collecting the
tank truck loading vapors and sending the vapors through a closed vent system to a
control device that meets the regulations. To load the truck, the facility proposes to
attach/bolt a metal plate to the opened dome. The plate has the loading hose and vapor
recovery line attached to it. While disconnecting the tank truck, it is necessary to remove
the metal plate from the tank truck exposing the contents of the truck to the atmosphere
until the dome lid is secured. Does this type of loading meet Subpart EEEE regulations?
A23: No. The rule requires you to meet the pressure requirements at all times. The
retrofit system you are describing would be prone to leakage, even with the plate bolted
down and would not meet the pressure testing requirements. The majority of trucks are
equipped to be bottom loaded and the vapor return lines are mounted in the top panel
compartments and they are equipped with sealed disconnect fittings and pressure relief
valves.
G. Equipment Leaks
Q24: What equipment leak standards are applicable at an affected facility where the
number of hours of service for the storage tanks is greater than 300 hours of organic
liquid service, yet related systems, such as transfer rack, pipeline and pipeline transfer
rack to storage tanks have less than 300 hours of OLD service?
A24: Each storage tank, transfer rack and associated pipeline is evaluated separately
against the 300 hours per year threshold. Therefore, the storage tank would be subject to
equipment leak requirements of the selected Subpart. Under §63.2346(c) for each pump,
valve, and sampling connection systems that operates in organic liquids service for at
least 300 hours per year, you must comply with the applicable requirements under 40
CFR Part 63, Subpart TT (Control Level 1), Subpart UU (Control Level 2), or Subpart H.
Note that equipment remains in HAP service even if the storage tank, transfer rack or
pipeline is not in use, unless the equipment is emptied and/or purged.
60
-------
Q25: Why do OLD recordkeeping and reporting requirements in §63.2396(e)(2)
address equipment associated with unloading transfer racks if the only requirements for
such unloading transfer racks are called out in §63.2343(a)?
A25: §63.2343 applies to the transfer rack which unloads organic liquids, not to the
equipment components associated with the rack. Equipment components are subject to
the leak detection and repair requirements set forth in the rule, e.g., §63.2346(c) and item
4 of Table 4. If you only have sources that are described by §63.2343 (i.e., you have no
equipment leak components in organic liquids service for at least 300 hours per year),
then the requirements at §63.2396(e)(2) do not apply.
Q26: Do sources have 180 days after the compliance date to tag and conduct the first
round of monitoring on all pumps/valves, and comply with the sampling connection
system provisions (under TT/UU/H)? If so, is it correct that some of the first compliance
reports due July 30, 2007, may not have fugitive monitoring results to report?
A26: Yes. Sources have 180 days after the compliance date to tag and conduct the first
round of required monitoring. The first periodic report, due postmarked by July 30,
2007, would not contain information on periodic monitoring or work practice (LDAR)
because of the 180-day timeframe for conducting the initial compliance demonstrations
ends after the submittal date.

4.0 GLOSSARY OF DEFINED TERMS
Actual annual average temperature, for organic liquids, means the temperature
determined using the following methods.
(1) For heated or cooled storage tanks: use the calculated annual average temperature of
the stored organic liquid as determined from a design analysis of the storage tank.
(2) For ambient temperature storage tanks:
(i) use the annual average of the local (nearest) normal daily mean temperatures reported
by the National Climatic Data Center; or
(ii) use any other method that the EPA approves.
Administrator means the Administrator of the United States Environmental Protection
Agency or his or her authorized representative (e.g., a State that has been delegated the
authority to implement the provisions of this part).
Affected source means the collection of equipment, activities, or both within a single
contiguous area and under common control that is included in a section 112(c) source
category or subcategory for which a section 112(d) standard or other relevant standard is
established pursuant to section 112 of the Act. Each relevant standard will define the
"affected source," as defined in this paragraph unless a different definition is warranted
based on a published justification as to why this definition would result in significant
administrative, practical, or implementation problems and why the different definition
would resolve those problems. The term "affected source," as used in this part, is separate
and distinct from any other use of that term in EPA regulations such as those
implementing title IV of the Act. Affected source may be defined differently for part 63
than affected facility and stationary source in parts 60 and 61, respectively. This
definition of "affected source," and the procedures for adopting an alternative definition
of "affected source," shall apply to each section 112(d) standard for which the initial
proposed rule is signed by the Administrator after June 30, 2002.
Alternative emission limitation means conditions established pursuant to sections
I I2(i)(5) or I 12(i)(6) of the Act by the Administrator or by a State with an approved
permit program.
Alternative emission standard means an alternative means of emission limitation that,
after notice and opportunity for public comment, has been demonstrated by an owner or
operator to the Administrator's satisfaction to achieve a reduction in emissions of any air
pollutant at least equivalent to the reduction in emissions of such pollutant achieved
under a relevant design, equipment, work practice, or operational emission standard, or
combination thereof, established under this part pursuant to section 112(h) of the Act.
Alternative test method means any method of sampling and analyzing for an air
pollutant that is not a test method in this chapter and that has been demonstrated to the
Administrator's satisfaction, using Method 301 in Appendix A of this part, to produce
62
-------
results adequate for the Administrator's determination that it may be used in place of a
test method specified in this part.
Approved permit program means a State permit program approved by the
Administrator as meeting the requirements of part 70 of this chapter or a Federal permit
program established in this chapter pursuant to title V of the Act (42 U.S.C. 7661).
Area source means any stationary source of hazardous air pollutants that is not a major
source as defined in this part.
Annual average true vapor pressure means the equilibrium partial pressure exerted by
the total Table 1 organic HAP in the stored or transferred organic liquid. For the purpose
of determining if a liquid meets the definition of an organic liquid, the vapor pressure is
determined using standard conditions of 77 degrees F and 29.92 inches of mercury. For
the purpose of determining whether an organic liquid meets the applicability criteria in
Table 2, items 1 through 6, to this subpart, use the actual annual average temperature as
defined in this subpart. The vapor pressure value in either of these cases is determined:
(1) In accordance with methods described in American Petroleum Institute Publication
2517, Evaporative Loss from External Floating-Roof Tanks (incorporated by reference,
see §63.14);
(2) Using standard reference texts;
(3) By the American Society for Testing and Materials Method D2879-83, 96
(incorporated by reference, see §63.14); or
(4) Using any other method that the EPA approves.
Bottoms receiver means a tank that collects distillation bottoms before the stream is sent
for storage or for further processing downstream.
Capacity means the volume of liquid that is capable of being stored in a vessel,
determined by multiplying the vessel's internal cross-sectional area by the internal height
of the shell.
Cargo tank means a liquid-carrying tank permanently attached and forming an integral
part of a motor vehicle or truck trailer. This term also refers to the entire cargo tank
motor vehicle or trailer. For the purpose of this subpart, vacuum trucks used exclusively
for maintenance or spill response are not considered cargo tanks.
Closed-loop system means an enclosed system that returns process fluid to the process
and is not vented to the atmosphere except through a closed-vent system.
Closed-purge system means a system or combination of system and portable containers,
to capture purged liquids. Containers must be covered or closed when not being filled or
emptied.
Closed vent system means a system that is not open to the atmosphere and is composed
of piping, ductwork, connections, and, if necessary, flow-inducing devices that transport
63
-------
gas or vapors from an emission point to a control device. This system does not include
the vapor collection system that is part of some transport vehicles or the loading arm or
hose that is used for vapor return. For transfer racks, the closed vent system begins at,
and includes, the first block valve on the downstream side of the loading arm or hose
used to convey displaced vapors.
Closed vent system 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 closed vent system or part of a closed vent
system consistent with safety constraints and during which repairs can be effected. An
unscheduled work practice or operational procedure that stops production from a process
unit or part of a process unit for less than 24 hours is not a closed vent system shutdown.
An unscheduled work practice or operational 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 closed vent system or part of the closed vent system of materials and start up
the unit, and would result in greater emissions than delay of repair of leaking components
until the next scheduled closed vent system shutdown, is not a closed vent system
shutdown. The use of spare equipment and technically feasible bypassing of equipment
without stopping production are not closed vent system shutdowns.
Closure device means a cover, cap, hatch, lid, plug, seal, valve, or other type of fitting
that prevents or reduces air emissions to the atmosphere by blocking an opening in a
container or its cover when the device is secured in the closed position. Closure devices
include devices that are detachable from the container (e.g., a drum head, a threaded
plug), manually operated (e.g., a hinged dumpster lid, a truck tank hatch), or
automatically operated (e.g., a spring loaded pressure relief valve).
Combustion device means an individual unit of equipment, such as a flare, oxidizer,
catalytic oxidizer, process heater, or boiler, used for the combustion of organic emissions.
Commenced means, with respect to construction or reconstruction of an affected source,
that an owner or operator has undertaken a continuous program of construction or
reconstruction or that an owner or operator has entered into a contractual obligation to
undertake and complete, within a reasonable time, a continuous program of construction
or reconstruction.
Compliance date means the date by which an affected source is required to be in
compliance with a relevant standard, limitation, prohibition, or any federally enforceable
requirement established by the Administrator (or a State with an approved permit
program) pursuant to section 112 of the Act.
Compliance schedule means: (1) In the case of an affected source that is in compliance
with all applicable requirements established under this part, a statement that the source
will continue to comply with such requirements; or
(2) In the case of an affected source that is required to comply with applicable
requirements by a future date, a statement that the source will meet such requirements on
64
-------
a timely basis and, if required by an applicable requirement, a detailed schedule of the
dates by which each step toward compliance will be reached; or
(3) In the case of an affected source not in compliance with all applicable requirements
established under this part, a schedule of remedial measures, including an enforceable
sequence of actions or operations with milestones and a schedule for the submission of
certified progress reports, where applicable, leading to compliance with a relevant
standard, limitation, prohibition, or any federally enforceable requirement established
pursuant to section 112 of the Act for which the affected source is not in compliance.
This compliance schedule shall resemble and be at least as stringent as that contained in
any judicial consent decree or administrative order to which the source is subject. Any
such schedule of compliance shall be supplemental to, and shall not sanction
noncompliance with, the applicable requirements on which it is based.
Connector means flanged, screwed, or other joined fittings used to connect two pipelines
or a pipeline and a piece of equipment. A common connector is a flange. Joined fittings
welded completely around the circumference of the interface are not considered
connectors for the purpose of this regulation. For the purpose of reporting and
recordkeeping, connector means joined fittings that are not inaccessible, ceramic, or
ceramic-lined (e.g., porcelain, glass, or glass-lined) as described in §63.1027(e)(2).
Construction means the on-site fabrication, erection, or installation of an affected
source. Construction does not include the removal of all equipment comprising an
affected source from an existing location and reinstallation of such equipment at a new
location. The owner or operator of an existing affected source that is relocated may elect
not to reinstall minor ancillary equipment including, but not limited to, piping, ductwork,
and valves. However, removal and reinstallation of an affected source will be construed
as reconstruction if it satisfies the criteria for reconstruction as defined in this section.
The costs of replacing minor ancillary equipment must be considered in determining
whether the existing affected source is reconstructed.
Continuous emission monitoring system (CEMS) means the total equipment that may
be required to meet the data acquisition and availability requirements of this part, used to
sample, condition (if applicable), analyze, and provide a record of emissions.
Continuous monitoring system (CMS) is a comprehensive term that may include, but is
not limited to, continuous emission monitoring systems, continuous opacity monitoring
systems, continuous parameter monitoring systems, or other manual or automatic
monitoring that is used for demonstrating compliance with an applicable regulation on a
continuous basis as defined by the regulation.
Container means a portable unit in which a material can be stored, transported, treated,
disposed of, or otherwise handled. Examples of containers include, but are not limited to,
drums and portable cargo containers known as "portable tanks" or "totes."
Control device means any combustion device, recovery device, recapture device, or any
combination of these devices used to comply with this subpart. Such equipment or
65
-------
devices include, but are not limited to, absorbers, adsorbers, condensers, and combustion
devices. Primary condensers, steam strippers, and fuel gas systems are not considered
control devices.
Control System means the combination of the closed vent system and the control
devices used to collect and control vapors or gases from a regulated emission source.
Crude oil means any of the naturally occurring liquids commonly referred to as crude
oil, regardless of specific physical properties. Only those crude oils downstream of the
first point of custody transfer after the production field are considered crude oils in this
subpart.
Custody transfer means the transfer of hydrocarbon liquids after processing and/or
treatment in the producing operations, or from storage tanks or automatic transfer
facilities to pipelines or any other forms of transportation.
Design evaluation means a procedure for evaluating control devices that complies with
the requirements in §63.985(b)(l)(i).
Deviation means any instance in which an affected source subject to this subpart, or
portion thereof, or an owner or operator of such a source:
(1) Fails to meet any requirement or obligation established by this subpart including, but
not limited to, any emission limitation (including any operating limit) or work practice
standard;
(2) Fails to meet any term or condition that is adopted to implement an applicable
requirement in this subpart, and that is included in the operating permit for any affected
source required to obtain such a permit; or
(3) Fails to meet any emission limitation (including any operating limit) or work practice
standard in this subpart during SSM.
Effective date means:
(1) With regard to an emission standard established under this part, the date of
promulgation in the Federal Register of such standard; or
(2) With regard to an alternative emission limitation or equivalent emission limitation
determined by the Administrator (or a State with an approved permit program), the date
that the alternative emission limitation or equivalent emission limitation becomes
effective according to the provisions of this part.
Emissions averaging is a way to comply with the emission limitations specified in a
relevant standard, whereby an affected source, if allowed under a subpart of this part,
may create emission credits by reducing emissions from specific points to a level below
that required by the relevant standard, and those credits are used to offset emissions from
points that are not controlled to the level required by the relevant standard.
66
-------
Emission limitation means an emission limit, opacity limit, operating limit, or visible
emission limit.
Emission standard means a national standard, limitation, prohibition, or other regulation
promulgated in a subpart of this part pursuant to sections 112(d), 112(h), or 112(f) of the
Act.
Empty container means a container for which either of the following conditions exists:
the container meets the conditions for an empty container specified in 40 CFR 261.7(b);
or all regulated-material has been removed from the container except for any regulated-
material that remains on the interior surfaces of the container as clingage or in pools on
the container bottom due to irregularities in the container.
Empty or emptying means the partial or complete removal of stored liquid from a
storage vessel. Storage vessels that contain liquid only as wall or bottom clingage, or in
pools due to bottom irregularities, are considered completely empty.
Equipment means each pump, compressor, agitator, pressure relief device, sampling
connection system, open-ended valve or line, valve, connector, surge control vessel,
bottoms receiver, and instrumentation system in organic hazardous air pollutant service;
and any control devices or systems required by this subpart.
Equipment leak component means each pump, valve, and sampling connection system
used in organic liquids service at an OLD operation. Valve types include control, globe,
gate, plug, and ball. Relief and check valves are excluded.
Existing source means any affected source that is not a new source.
First attempt at repair means to take action for the purpose of stopping or reducing
leakage of organic material to the atmosphere, followed by monitoring as specified in
§63.180 (b) and (c), as appropriate, to verify whether the leak is repaired, unless the
owner or operator determines by other means that the leak is not repaired.
Fixed capital cost means the capital needed to provide all the depreciable components of
an existing source.
Fuel gas means gases that are combusted to derive useful work or heat.
Fuel gas system means the offsite and onsite piping and control system that gathers
gaseous stream(s) generated by onsite operations, may blend them with other sources of
gas, and transports the gaseous stream for use as fuel gas in combustion devices or in in-
process combustion equipment such as furnaces and gas turbines, either singly or in
combination.
Fugitive emissions means those emissions from a stationary source that could not
reasonably pass through a stack, chimney, vent, or other functionally equivalent opening.
67
-------
Under section 112 of the Act, all fugitive emissions are to be considered in determining
whether a stationary source is a major source.
Gasoline means any petroleum distillate or petroleum distillate/alcohol blend having a
Reid vapor pressure of 21.6 kilopascals (4.0 pounds per square inch absolute (psia) or
greater which is used as a fuel for internal combustion engines. Aviation gasoline is
included in this definition.
Hard-piping means pipe or tubing that is manufactured and properly installed using
good engineering judgment and standards, such as ANSI B31.3.
Hazardous air pollutant means any air pollutant listed in or pursuant to section 112(b)
of the Act.
High throughput transfer rack means those transfer racks that transfer into transport
vehicles (for existing affected sources) or into transport vehicles and containers (for new
affected sources) a total of 11.8 million liters per year or greater of organic liquids.
In gas/vapor service means that a piece of equipment in organic hazardous air pollutant
service contains a gas or vapor at operating conditions.
In heavy liquid service means that a piece of equipment in organic hazardous air
pollutant service is not in gas/vapor service or in light liquid service.
In light liquid service means that a piece of equipment in organic hazardous air pollutant
service contains a liquid that meets the following conditions:
(1) The vapor pressure of one or more of the organic compounds is greater than 0.3
kilopascals at 20 °C,
(2) The total concentration of the pure organic compounds constituents having a vapor
pressure greater than 0.3 kilopascals at 20 °C is equal to or greater than 20 percent by
weight of the total process stream, and
(3) The fluid is a liquid at operating conditions.
Note: Vapor pressures may be determined by the methods described in 40 CFR
60.485(e)(l).
In liquid service means that a piece of equipment in organic hazardous air pollutant
service is not in gas/vapor service.
In organic hazardous air pollutant or in organic HAP service means that a piece of
equipment either contains or contacts a fluid (liquid or gas) that is at least 5 percent by
weight of total organic HAPs as determined according to the provisions of §63.180(d) of
this subpart. The provisions of §63.180(d) of this subpart also specify how to determine
that a piece of equipment is not in organic HAP service.
68
-------
In organic liquids service means that an equipment leak component contains or contacts
organic liquids having 5 percent by weight or greater of the organic HAP listed in Table 1
to this subpart.
In regulated material service means, for the purpose of this subpart, equipment which
meets the definition of "in VOC service", "in VHAP service", "in organic hazardous air
pollutant service", or "in other chemicals or groups of chemicals service" as defined in
the referencing subpart.
In volatile organic compound or in VOC service means that:
(1) The piece of equipment contains or contacts a process fluid that is at least 10 percent
VOC by weight (see 40 CFR 60.2 for the definition of VOC, and 40 CFR 60.485(d) to
determine whether a piece of equipment is not in VOC service); and
(2) The piece of equipment is not in heavy liquid service as defined in 40 CFR 60.481.
Instrumentation system means a group of equipment components used to condition and
convey a sample of the process fluid to analyzers and instruments for the purpose of
determining process operating conditions (e.g., composition, pressure, flow, etc.). Valves
and connectors are the predominant type of equipment used in instrumentation systems;
however, other types of equipment may also be included in these systems. Only valves
nominally 1.27 centimeters (0.5 inches) and smaller, and connectors nominally 1.91
centimeters (0.75 inches) and smaller in diameter are considered instrumentation systems
for the purposes of this subpart. Valves greater than nominally 1.27 centimeters (0.5
inches) and connectors greater than nominally 1.91 centimeters (0.75 inches) associated
with instrumentation systems are not considered part of instrumentation systems and
must be monitored individually.
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.
Low throughput transfer rack means those transfer racks that transfer into transport

unless the Administrator establishes a lesser quantity, or in the case of radionuclides,
different criteria from those specified in this sentence.
New affected source means the collection of equipment, activities, or both within a
single contiguous area and under common control that is included in a section 112(c)
source category or subcategory that is subject to a section 112(d) or other relevant
69
-------
standard for new sources. This definition of "new affected source," and the criteria to be
utilized in implementing it, shall apply to each section 112(d) standard for which the
initial proposed rule is signed by the Administrator after June 30, 2002. Each relevant
standard will define the term "new affected source," which will be the same as the
"affected source" unless a different collection is warranted based on consideration of
factors including:
(1) Emission reduction impacts of controlling individual sources versus groups of
sources;
(2) Cost effectiveness of controlling individual equipment;
(3) Flexibility to accommodate common control strategies;
(4) Cost/benefits of emissions averaging;
(5) Incentives for pollution prevention;

(1) For existing affected sources, each 3-year rolling average is based on actual facility-
level loading volume during each calendar year (January 1 through December 31) in the
3-year period. For calendar year 2004 only (the first year of the initial 3-year rolling
average), if an owner or operator of an affected source does not have actual loading
volume data for the time period from January 1, 2004, through February 2, 2004 (the time
period prior to the effective date of the OLD NESHAP), the owner or operator shall
compute a facility-level loading volume for this time period as follows: At the end of the
2004 calendar year, the owner or operator shall calculate a daily average facility-level
loading volume (based on the actual loading volume for February 3, 2004, through
December 31, 2004) and use that daily average to estimate the facility-level loading
volume for the period of time from January 1, 2004, through February 2, 2004. The
owner or operator shall then sum the estimated facility-level loading volume from
January 1, 2004, through February 2, 2004, and the actual facility-level loading volume
from February 3, 2004, through December 31, 2004, to calculate the annual facility-level
loading volume for calendar year 2004.
(2)(i) For new affected sources, the 3-year rolling average is calculated as an average of
three 12-month periods. An owner or operator must select as the beginning calculation
date with which to start the calculations as either the initial startup date of the new
affected source or the first day of the calendar month following the month in which
74
-------
startup occurs. Once selected, the date with which the calculations begin cannot be
changed.
(ii) The initial 3-year rolling average is based on the projected maximum facility-level
annual loading volume for each of the 3 years following the selected beginning
calculation date. The second 3-year rolling average is based on actual facility-level
loading volume for the first year of operation plus a new projected maximum facility-
level annual loading volume for second and third years following the selected beginning
calculation date. The third 3-year rolling average is based on actual facility-level loading
volume for the first 2 years of operation plus a new projected maximum annual facility-
level loading volume for the third year following the beginning calculation date.
Subsequent 3-year rolling averages are based on actual facility-level loading volume for
each year in the 3-year rolling average.
Transfer rack means a single system used to load organic liquids into, or unload organic
liquids out of, transport vehicles or containers. It includes all loading and unloading

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.
Vapor balancing system means: (1) a piping system that collects organic HAP vapors
displaced from transport vehicles or containers during loading and routes the collected
vapors to the storage tank from which the liquid being loaded originated or to another
storage tank connected to a common header. For containers, the piping system must
route the displaced vapors directly to the appropriate storage tank or to another storage
tank connected to a common header in order to qualify as a vapor balancing system; or
(2) a piping system that collects organic HAP vapors displaced from the loading of a
storage tank and routes the collected vapors to the transport vehicle from which the
storage tank is filled.
Vapor collection system means any equipment located at the source (i.e., at the OLD
operation) that is not open to the atmosphere; that is composed of piping, connections,
and, if necessary, flow-inducing devices; and that is used for:
(1) Containing and conveying vapors displaced during the loading of transport vehicles
to a control device;
(2) Containing and directly conveying vapors displaced during the loading of containers;
or
(3) Vapor balancing. This does not include any of the vapor collection equipment that is
installed on the transport vehicle.
75
-------
Vapor-mounted seal means a rim seal designed not to be in contact with the stored
liquid. Vapor-mounted seals may include, but are not limited to, resilient seals and
flexible wiper seals.
Vapor-tight transport vehicle means a transport vehicle that has been demonstrated to
be vapor-tight. To be considered vapor-tight, a transport vehicle equipped with vapor
collection equipment must undergo a pressure change of no more than 250 pascals (1
inch of water) within 5 minutes after it is pressurized to 4,500 pascals (18 inches of
water). This capability must be demonstrated annually using the procedures specified in
EPA Method 27 of 40 CFR part 60, appendix A. For all other transport vehicles, vapor
tightness is demonstrated by performing the U.S. DOT pressure test procedures for tank
cars and cargo tanks.
