ABSTRACT
The purpose of this manual is to enhance an inspector's ability to conduct more
complete and effective inspections at facilities in the chemical industry that are subject
to Federal equipment leak regulations. Equipment leak standards are designed to reduce
or eliminate emissions of volatile organic compounds (VOCs), volatile hazardous air
pollutants (VHAPs), and organic HAPs from the miles of piping and numerous
components found in chemical manufacturing processes.
This document is divided into three volumes. The first volume is a manual for
inspectors; the second and third volumes describe regulations that apply to the chemical
manufacturing and the petroleum refining industries, respectively.
Volume I has five chapters dedicated to helping an inspector:
• Chapter 1 states the goals, background, approaches to rule enforcement, and
organization of the document.
• Chapter 2 addresses applicability determinations: ensuring the correct rules are
being complied with at a facility, determining whether all appropriate
components have been identified, and ensuring the components are properly
classified by service.
» Chapter 3 discusses reporting and recordkeeping requirements for NSPS,
NESHAP, HON, and RCRA (recordkeeping only), and strategies for reviewing
reports and records.
• Chapter 4 covers on-site inspections: walk-throughs and inspections with the
inspector monitoring for leaks. It addresses pre-inspection activities, timing and
scope, interviews, leak monitoring evaluations, inspections of the process area
and records, and post-inspection reviews and reports.
• Chapter 5 discusses recommended inspection techniques and procedures.
Volume n tackles the equipment leak regulations applicable to the chemical
manufacturing industry.
• The first three appendices of Volume II summarize the regulations of 40
CFR Part 60 Subpart W, Part 61 Subparts J and V, Part 63 Subparts H and
I, Part 264 Subpart BB, and Part 265 Subpart BB; detail the differences
among the regulations; and give the requirements grouped by component.
• Appendix D describes the regulated equipment.
• Appendix E contains the "Method 21" approach to leak detection.
* Appendix F lists chemical manufacturing processes that are subject to HON.
• Appendix G lists organic HAPs that are subject to HON.
* Appendix H lists manufacturing processes and associated organic HAP
emissions that are subject to HON.
-------
Volume in contains the equipment leak regulations applicable to the petroleum refining
industry.
• The three appendices of Volume HI summarize the regulations of 40 CFR Part
60 Subparts DDD, GGG, KKK, and QQQ, and Part 63 Subpart CC; detail the

ENFORCEMENT, AND ORGANIZATION OF DOCUMENT
1.1 SCOPE OF MANUAL AND STATEMENT OF PURPOSE
The purpose of this manual is to provide guidance to enhance an inspector's
ability to conduct more complete and effective inspections at facilities in the chemical
industry subject to Federal equipment leak regulations. Inspections are typically
conducted not only to determine whether a facility is in compliance with a regulation,
but also to evaluate the effectiveness of a facility's implementation of a program.
Equipment leak inspections involve two separate, but equally important
activities: evaluation of equipment leak program records and reports and on-site
inspections. To effectively conduct these activities, an inspector must be able to:
• Determine which Federal equipment leak regulations are applicable to a
chemical industry facility.
• Understand the overall approach of using both equipment standards and
leak detection and repair standards to achieve reductions in emissions
from equipment leaks.
• Determine if a source is complying with all the requirements of
component identification, component marking, equipment design,
monitoring, repair, recordkeeping, and reporting.
• Understand the use of alternate standards.
• Understand the volatile organic compounds (VOC) analyzer performance
specifications required by U.S. EPA Method 21.
• Understand the basic operating principles of flame ionization analyzers,
photoionization analyzers, and catalytic combustion analyzers.

-------
• Evaluate source personnel's calibration procedures and records.
» Evaluate field monitoring procedures used by source personnel to detect
leaks from regulated components.
This manual addresses seven Federal equipment leak regulations that affect the
chemical industry. These regulations, found in the Code of Federal Regulations (CFR),
are:
• 40 CFR Part 60, Subpart W - SOCMI Equipment Leaks New Source
Performance Standard (NSPS)
• 40 CFR Part 61, Subpart J— Benzene Equipment Leaks National
Emission Standard for Hazardous Air Pollutants (NESHAP)
• 40 CFR Part 61, Subpart V - NESHAP Equipment Leaks
• 40 CFR Part 63, Subpart H — Organic Hazardous Air Pollutants (RAP)
Equipment Leak NESHAP
• 40 CFR Part 63, Subpart I - Organic HAP Equipment Leak NESHAP
for Certain Processes
• 40 CFR Part 264, Subpart BB — Air Emission Standards for Equipment
Leaks for TSDFs
• 40 CFR Part 265, Subpart BB — Air Emission Standards for Equipment
Leaks for Interim Program TSDFs
Due to the similarity among many of the equipment leak regulations, the
guidance in this manual may be of assistance to inspectors responsible for conducting
inspections at facilities complying with State or local equipment regulations and at other
types of facilities (e.g., petroleum refineries) subject to other Federal equipment leak
regulations. The focus of this manual, however, is the seven Federal regulations
identified above, which affect facilities in the chemical industry. These regulations are
presented in Volume n, Appendices A, B, and C. Regulations that affect the petroleum
refinery industry are presented in Volume HI.
1.2 BACKGROUND
1.2.1 Introduction; What are equipment leaks and why are they of concern?
Chemical manufacturing processes include miles of piping and numerous
components which convey petrochemical feedstocks, water, steam, and intermediate
and final products. Emissions from equipment leaks occur in the form of gases or
liquids that escape to the atmosphere through many types of connection points (e.g.,
flanges, threaded fittings, etc.) or through the moving parts of valves, pumps,
compressors, pressure relief devices, and certain types of process equipment.
1-2
-------
Equipment leaks are primarily defined within the above regulations on the basis
of a detection instrument which reads the airborne concentration of volatile organic
carbons at a potential leak point on a parts per million (ppm) basis. If the leak exceeds
the threshold definition of the applicable regulation, repair of the leaking equipment is
required. How the instrument is used (leak monitoring procedure) and performance
criteria for the instrument are defined in Method 21 of 40 CFR Part 60, Appendix A
(see Volume n, Appendix E). Equipment leaks also may be defined on the basis of
visual observation of certain types of equipment. Each regulation includes leak
definitions for specific types of equipment (see Volume n, Appendix C).
Equipment leak standards are designed to reduce or eliminate emissions of
VOCs, volatile hazardous air pollutants (VHAPs), and organic HAPs. VOCs, along
with nitrogen oxides (NO*) and ultraviolet radiation, contribute to ozone production.
Ozone is one of the criteria pollutants for which a national ambient air quality standard
(NAAQS) is designated under Section 109 of the Clean Air Act, and nonattainment of
the ozone NAAQS is a serious problem in the United States. VHAPs and organic
HAPs (collectively referred to as HAPs in this document) are controlled because such
air pollutants can pose a health risk for humans, in the form of direct worker exposure
or as a contribution to air pollution affecting a broader population.
Equipment leak emissions of VOCs and HAPs from the source categories •
discussed above constitute a significant source of air pollutants. For example,
equipment leak emissions are estimated to be responsible for over 50 percent of the
total VOC emissions from refineries or about 10,000 tons per year in California based
on the 1990 emissions inventory of the California Air Resources Board. Significant
emissions from equipment leaks are also reported by the chemical manufacturing
industries to the Toxic Chemical Release Inventory, as required by Section 313 of the
Emergency Planning and Community Right-to-Know Act. For example, all
manufacturers of chemicals and allied products (Standard Industrial Classification (SIC)
Code 2800) reported in 1993 that fugitive emissions accounted for approximately
250,000 tons of air emissions. Fugitive emissions from equipment leaks are a
significant subset of total fugitive emissions.
Federal equipment leak standards implemented during the 1980's were estimated
to reduce VOC and HAP emissions between 55 and 68 percent from facilities affected
by the standards. For example, the EPA estimated the VOC emissions from facilities
affected by the synthetic organic chemical manufacturing industry (SOCMI) standards
would be reduced from approximately 91,500 tons per year (tpy) to 40,700 tpy--a 56
percent reduction. The emission reduction estimate for benzene sources at chemical
manufacturing facilities is 68 percent. The Hazardous Organic NESHAP (HON)
standards, as well as some State and local standards, are intended to achieve even
greater reductions of VOC and HAP fugitive emissions.

-------
1.2.2 Components
A general set of equipment is covered by all of the equipment leak standards
affecting chemical facilities. This includes pumps, compressors, pressure relief
devices, open-ended valves or lines, valves, sampling connections, flanges and other
connectors. In addition, all of the standards include any devices or systems (i.e.,
alarms, or dual mechanical seals) required to satisfy performance or equipment
standards. The equipment leak standards also identify requirements for closed-vent
systems and control devices that may be used to comply with the regulations.
Additional equipment is covered only by specific standards. For example,
product accumulator vessels are addressed only by the HON and benzene NESHAP,
and agitators are addressed only by the HON. The HON also addresses instrumentation
systems.
Leak Detection and Repair (LDAR) programs (see Section 1.2.3.1) affect valves
and pumps and other components. Appendix C in Volume n provides a component-by-
component summary of the equipment leak regulations. Specific regulated components
are discussed in greater detail in Volume n, Appendix D.
1.2.2.1 Pomps
Pumps are used extensively in chemical manufacturing facilities for moving
fluids. The most widely used pump is the centrifugal pump. Other types of pumps that
also may be used are the positive-displacement, reciprocating and rotary action, and
special canned-motor and diaphragm pumps.
Chemicals transferred by pumps can leak at the point of contact between the
moving shaft and stationary casing. To isolate the pump's interior from the
atmosphere, all pumps, except the seal-less type (canned-motor and diaphragm), require
a seal at the point where the shaft penetrates the housing. The most commonly used
seals in these pumps are packed and mechanical. However, no seal system is perfect,
and many pumps are equipped with a closed-vent system.
1.2.2.2 Compressors
Centrifugal, reciprocating, and rotary compressors are used in chemical
manufacturing facilities. The centrifugal compressor uses a rotating element or series
of elements containing curved blades to increase the pressure of a gas by centrifugal
force. Reciprocating and rotary compressors increase pressure by confining the gas in
a cavity and progressively decreasing the volume of the cavity. Reciprocating
compressors usually use a piston and cylinder arrangement, while rotary compressors
use rotating elements such as lobed impellers or sliding vanes.
1-4
-------
As with pumps, seals are required to prevent leakage from compressors. Rotary
shaft seals for compressors may be labyrinth, restrictive carbon rings, mechanical
contact, or liquid film. All of these seals are leak restriction devices, but none of them
completely eliminate leakage. To respond to leakage, many compressors are equipped
with ports in the seal area that evacuate collected gases to a control device.
1.2.2.3 Pressure Relief Devices
Engineering codes require the use of pressure-relieving devices or systems in
applications where the process pressure may exceed the maximum allowable working
pressure of the vessel. The pressure relief valve is the most common type of pressure-
relieving device used. Typically, relief valves are spring-loaded and designed to open
when the system pressure exceeds a set pressure, allowing the release of vapors or
liquids until the system pressure is reduced to its normal operating level. When the
normal pressure is re-attained, the valve reseats and a seal is again formed. The seal is
a disc on a seat, and a leak through this seal is a potential source of fugitive VOC and
HAP emissions. The potential causes of leakage from relief valves are "simmering or
popping" (a condition that occurs when the system pressure comes close to the set
pressure of the valve); improper reseating of the valve after a relieving operation; and
corrosion or degradation of the valve seat.
Rupture discs also may be used to relieve pressure in process units. These discs
are made of a material that ruptures when a set pressure is exceeded, thus allowing the
system to depressurize. The advantage of a ruptured disc is that the disc seals tightly
and does not allow any emissions to escape from the system during normal operations.
When the disc ruptures, however, the system will depressurize until atmospheric
conditions are obtained, unless the disc is used with a pressure relief valve.
1.2.2.4 Sampling Connections
Process unit operations are checked periodically by routine analysis of
feedstocks and products. To obtain representative samples for these analyses, sampling
lines first must be purged. If the flushing liquid is not controlled, it could be drained
onto the ground or into a process drain where it would evaporate and release emissions
to the atmosphere. Closed-loop sampling systems control the purged process fluid by
returning it directly to the process line, collecting and recycling the fluid, or
transporting the fluid to a control device.
1.2.2.5 Open-ended Lines or Open Valves
Some valves are installed in a system so that they function with the downstream
line open to the atmosphere. Open-ended lines, which are used mainly in intermittent
service for sampling and venting, include purge, drain, and sampling lines. Some
1-5
-------
open-ended lines are needed to preserve product purity. Normally, these are installed
between multi-use product lines to prevent products from collecting in cross-tie lines
during valve seat leakage. A faulty valve seat or incompletely closed valve would
result in leakage through the valve, releasing emissions to the atmosphere.
1.2.2.6 Process Valves
One of the most common pieces of equipment affected by these standards is the
process valve. Commonly used types are control, globe, gate, plug, ball, relief, and
check valves. All except the relief valve (see Section 1.2.2.3) and check valve are
activated through a valve stem, which may have either a rotational or linear motion,
depending on the design. The valve stem requires a seal to isolate the process fluid
inside the valve from the atmosphere. The possibility of a leak through this seal makes
it a potential source of fugitive emissions. Since a check valve has no stem or
subsequent packing gland, it is not considered a potential source of fugitive emissions
and is not subject to the standards.
The stem can be sealed to prevent leakage by using a packing gland or O-ring
seals. Valves that require the stem to move in and out with or without rotation must
use a packing gland. Conventional packing glands are suited for a wide variety of
packing material. The most common are various types of braided asbestos that contain
lubricants. Other packing materials include graphite, graphite-impregnated fibers, and
tetrafluorethylene polymer. The packing material used depends on the valve application
and configuration. These conventional packing glands can be used over a range of
operating temperatures, but at high pressures, these glands must be quite tight to obtain
a good seal.
Elastomeric O-rings also are used for sealing process valves. These O-rings
provide good sealing, but are not suitable if sliding motion occurs through the packing
gland. These seals are used rarely in high pressure service, and operating temperatures
are limited by the seal material.
Bellows seals are more effective for preventing process fluid leaks than the
conventional packing gland or any other gland-seal arrangement. This type of seal
incorporates a formed metal bellows that makes a barrier between the disc and body
bonnet joint. The bellows is the weak point of this type of system, and service life can
be quite variable. Consequently, this type of seal normally is backed up with a
conventional packing gland and often is fitted with a leak detector in case of failure.
A diaphragm may be used to isolate the working parts of the valve and the
environment from the process liquid. The diaphragm also may be used to control the
flow of the process fluid. In this design, a compressor component pushes the
diaphragm toward the valve bottom, throttling the flow. The diaphragm and
1-6
-------
compressor are connected in a manner so that separating them is impossible under
normal working conditions. When the diaphragm reaches the valve bottom, it seats
firmly against the bottom, forming a leak-proof seal. This configuration is
recommended for fluids containing solid particles and for medium-pressure service.
Depending on the diaphragm material, Ms type of valve can be used at temperatures up
to 205°C and in severe acid solutions. If the seal fails, however, a valve using a
diaphragm seal can become a source of fugitive emissions.
1.2.2.7 Flanges and Other Connectors
Flanges are bolted, gasket-sealed junctions used wherever pipes or other
equipment such as vessels, pumps, valves, and heat exchangers may require isolation or
removal. Connectors are all other nonwelded fittings that serve a similar purpose to
flanges, which also allow bends in pipes (elbows), joining two pipes (couplings), or
joining three or four pipes (tees or crosses). Connectors typically are threaded.
Flanges may become fugitive emissions sources when leakage occurs because of
improperly chosen gaskets or poorly assembled flanges. The primary cause of flange
leakage is thermal stress, which causes deformation of the seal between the flange
faces. Threaded connectors may leak if the threads become damaged or corroded or if
tightened without sufficient lubrication or torque.
1.2.2.S Product Accumulator Vessels. Bottoms Receivers., and Separator
Vessels
Product accumulator vessels include overhead and bottoms receiver vessels used
with fractionation columns and product separator vessels used in series with reactor
vessels to separate reaction products. Accumulator vessels can be vented directly to the
atmosphere or indirectly through a blowdown drum or vacuum system. When an
accumulator vessel contains benzene and other HAPs and vents to the atmosphere,
emissions will occur.
1.2.2.9 Agitators
Agitators are used to stir or blend chemicals. Like pumps and compressors,
agitators may leak organic chemicals at the point where the shaft penetrates the casing.
Consequently, seals are required to minimize fugitive emissions. Four seal
arrangements commonly are used with agitators: compression packing (packed seal),
mechanical seals, hydraulic seals, and lip seals. Packed seals for agitators are very
similar in design and application to packed seals for pumps.
Although mechanical seals are more costly than the other three types of seals,
they offer a greatly reduced leakage rate to offset their higher cost. Furthermore, the
1-7
-------
maintenance frequency of mechanical seals is one-half to one-fourth that of packed
seals. At pressures greater than 1,140 kPa (150 psig), the leakage rate and maintenance
frequency are so superior that the use of packed seals on agitators is rare. As with
packed seals, the mechanical seals for agitators are similar in design and application to
the mechanical seals for pumps.
1.2.2.10 Instrumentation Systems
Instrumentation systems consist of smaller pipes and tubing that carry samples
of process fluids to be analyzed to determine process operating conditions or to systems
for measurement of process conditions.
1.2.2.11 Cloged-Vent Systems and Control Devices
A closed-vent system can be used to collect and dispose of gaseous emissions
from seal oil degassing vents, pump and compressor seal leakage, relief valve leakage,
and relief valve discharges because of over-pressure operation. A closed-vent system
consists of piping connectors, flame arresters, and, if necessary, flow-inducing devices.
Closed-vent systems are designed and operated so that all emissions are transported to a
control device without leakage to the atmosphere.
Several types of control devices can be used to dispose of VOC and HAP
emissions captured in the closed-vent system. Incineration, carbon adsorption, and
condensation are three control methods that typically are applied.
1.2.3 Leak Minimization Standards
Equipment leak standards are designed to control emission leaks from regulated
equipment through the application of work practices, equipment standards, and
operational practices. The work practice most commonly applied to control equipment
leaks is the LDAR program. Equipment practices include the use of specific types of
components, equipment design standards or specifications, and operational standards
for certain types of equipment. Equipment practices are evaluated using performance
standards that provide a basis for monitoring or substantiating the effectiveness of such
control practices.
1.2.3.1 Leak Detection and Repair
LDAR programs consist of two phases: (1) monitoring potential fugitive
emission sources within a process unit to detect leaks, and (2) repair or replacement of
the leaking component.
1-8
-------
The level of emission reduction achieved by a LDAR program is affected by
several factors. The three main factors are monitoring interval, leak definition, and
repair interval:
» Monitoring interval—The monitoring interval is the frequency at which
individual component monitoring is conducted. For example, valves are
generally required to be monitored once a month using a leak detection
instrument, but the monitoring interval may be extended to once every
quarter for each valve that has not leaked for two successive months.
The LDAR programs also specify weekly visual inspections of pumps
and compressors for indications of liquids dripping from the seals.
• Leak definition—The leak definition is the VOC (or HAP) concentration
observed during monitoring with a leak detection instrument that exceeds
the threshold standard for the applicable regulation. Leaks may also be
defined on the basis of visual inspections. In other cases, monitoring is
required if certain indications of leaks are observed.
* Repair interval—The repair interval is defined as the length of time
allowed between detection of a leak and repair of the leak. When a leak
is detected, the affected component is required to be repaired as soon as
practicable, but not later than 15 calendar days after the leak is detected,
unless the conditions described under "Delay of Repair" (later in this
section) are met.
For each component, the first attempt at repair is to be made no later than five
calendar days after each leak is detected. First attempts at repair include, but are not
limited to, the following best practices, where practicable and appropriate:
* Tightening of bonnet bolts
* Replacement of bonnet bolts
* Tightening of packing gland nuts
• Injection of lubricant into lubricated packing
Other factors that can improve the efficiency of an LDAR program that are not
addressed by the standards include training programs for equipment monitoring
personnel and tracking systems that address the cost efficiency of alternative equipment
(e.g., competing brands of valves hi a specific application).
1-9
-------
1.2.3.2 Equipment. Design. Operational, and Performance Standards
Equipment standards refer to the use of specific types of components. Design
standards include requirements for dual mechanical seals, closed purge and vent
systems, caps, blind flanges, second valves, and control equipment specifications
associated with flares and enclosed combustion devices.
Certain equipment operations, e.g., the proper sequence for closing double
blocks and bleed valves or the requirement to maintain a pilot flame in flares, are
regulated through implementing operational standards.
Performance standards refer to no detectable emissions and percent reduction
efficiency for control devices. Annual monitoring is used for components subject to the
"no detectable emissions" requirement, which requires emissions of less than 500 ppmv
above background levels. No detectable emissions components include pumps,
compressors, valves (specifically designated for no detectable emissions), pressure
relief devices in gas/vapor service, and closed-vent systems for both NSPSs and
NESHAPs.
1.2.4 Eederal Equipment Leak Regulations
Federal equipment leak regulations affecting chemical manufacturing facilities
consist of standards promulgated under the NSPS, NESHAP, and the Resource
Conservation and Recovery Act (RCRA). NSPSs are implemented under Section 111
of the Clean Air Act and apply to newly constructed stationary sources—those sources
constructed after the date that an NSPS is proposed in the Federal Register. NSPSs
become effective upon promulgation. In addition, existing stationary sources (sources
existing prior to the NSPS proposal date) can become subject to an NSPS if they are
modified or reconstructed after the NSPS proposal date. A degree of national
uniformity to air pollution standards is established through NSPSs. Such uniformity
tends to preclude situations in which certain States could attract new industries as a
result of relaxed standards, relative to other States.
NESHAPs, which are implemented under Section 112 of the Clean Air Act,
apply to both new and existing stationary sources. NESHAPs are intended to control
hazardous pollutants such as carcinogens or other serious disease-causing agents.
Formerly, they were developed and implemented for individual pollutants, but this
proved to be an extremely cumbersome and slow-moving process. By 1990, NESHAPs
had been established for only eight pollutants. Of these, equipment leak regulations
were applied only to benzene and vinyl chloride. The Clean Air Act Amendments of
1990 (CAAA) have changed the approach for controlling hazardous air pollutants. In
the CAAA, 189 chemicals are identified as air toxics that will be controlled on a source
category basis. A subset of the listed chemicals will be regulated under the HON.
1-10
-------
As a class, organic air emissions at hazardous waste treatment, storage, and
disposal facilities (TSDFs) are regulated under Subtitle C of RCRA. Final standards
are established in the rale to limit leaks from equipment (e.g., pumps and valves) that
contains or contacts hazardous waste streams with 10 percent or more total organics.
The final standards incorporate, or closely follow, many of the provisions of the
equipment leak NSPS and the benzene NESHAP. These standards are promulgated
under authority of Section 3004 of the Hazardous and Solid Waste Amendments to
RCRA and are incorporated into Parts 264 and 265 (Subpart BB), Air Emission
Standards for Owners and Operators of Hazardous Waste Treatment, Storage, and
Disposal Facilities (U.S. EPA, 1990b).
1.2.4.1 Federally Regulated Source Categories - NSPS
The NSPS equipment leak standards for the SOCMI are in Subpart W of 40
CFR Part 60, and sections (§) of this standard are found in §60.480 through §60.489.
The proposal and applicability date for Subpart W is January 5, 1981. The rale was
promulgated on October 18, 1983.
1.2.4.2 Sources Subject to NESHAP Regulations
NESHAPs have been established for equipment leaks of two designated VHAPs-
-benzene and vinyl chloride. Only the benzene NESHAP is applicable to chemical
manufacturing facilities.
The NESHAPs are found in 40 CFR Part 61. Part 61 contains the national
emission standards for hazardous air pollutants, including the folio whig subparts:
« Subpart J specifies the national emission standard for equipment leaks of
benzene and basically incorporates Subpart V as its standards. Subpart J
is found in §61.110 through §61.112. Subpart J was promulgated on
June 6, 1984.
• Subpart V contains the national emission standard for VHAP equipment
leaks. This subpart contains generic provisions and standards that are
incorporated by reference in 40 CFR 61, Subpart J. Subpart V is found
in §61.240 through §61.247. Subpart V was promulgated on June 6,
1984.
1-11
-------
1.2.4.3 Hazardous Organic National Emission Standard (HON)
The HON for equipment leaks at organic chemical plants is found at 40 CFR
Part 63, Subpart H, in §63.160 through §63.182. These standards apply to equipment
in organic hazardous air pollutant service for 300 or more hours per year. The
chemical manufacturing processes and organic HAPs subject to the rule are published
in Tables 1 and 2 of Subpart F to 40 CFR Part 63 (see Volume H, Appendices F
andG).
Subpart H standards also apply to some additional processes that produce certain
butadienes, chlorine, or styrene-based products. These processes are addressed in
Subpart I of 40 CFR 63 (see Volume H, Appendix H) at §63.190 through §63.193.
The HON was promulgated on April 22, 1994.
A number of the manufacturing processes listed under the HON also contain
equipment subject to NSPS or NESHAP equipment leak standards. Wherever such
overlapping rules apply, the HON takes precedence.
1.2.4.4 Hazardous Waste Facility Emission Standards
Organic air emissions at hazardous waste TSDFs are found at Parts 264 and 265
(Subpart BB), Air Emission Standards for Owners and Operators of Hazardous Waste
Treatment, Storage, and Disposal Facilities and Air Emissions Standards for Owners
and Operators of Interim Status Hazardous Waste Treatment, Storage and Disposal
Facilities, respectively. The regulations may be found at §264.1050 through §264.1065
and §265.1050 through §265.1064. The rules were both promulgated on June 21,
1990.
1.3 APPROACHES TO RULE ENFORCEMENT
Reports, recordkeeping requirements, and inspections form the basis of
assessing compliance with the Federal equipment leak standards. Inspections require
the evaluation of records and reports as well as the performance of on-site inspections,
including leak detection. Both activities are necessary to me accomplishment of
effective regulatory oversight.
1.3.1 Review of Reports and Recordkeeping
The review of records and reports can encompass two separate functions: (1)
determination that the records and reports are in compliance with the applicable
standards, and (2) use of records and reports in the performance of on-site inspections.
One of the goals of this manual is to assist inspectors in evaluating the often
1-12
-------
complicated and voluminous records that are an essential part of the equipment leak
programs. The records and reports required by the Federal equipment leak standards
are essential elements for the demonstration of compliance by the regulated facility. It
should be noted that these regulations are complicated and are not uniform from one
category to another. It is imperative therefore, that the inspector be thoroughly
knowledgeable of the source specific regulations before conducting an inspection. This
will aid the inspector in recognizing what types of information are important for the
compliance determination as well as providing a means of preparation for site visits and
inspections.
1.3.2 On-Site Inspections
On-site inspections can encompass the direct monitoring of regulated equipment
and measurement of equipment leaks as well as observational techniques addressing
plant procedures, equipment usage, and evaluation of monitoring and testing performed
by the plant. One goal of this manual is to provide guidance in the development and
implementation of direct monitoring inspections. Another goal is to enable the
inspector, through observational techniques, to determine if plant personnel are in full
compliance with EPA Method 21 field monitoring techniques and if they are adequately
identifying regulated and/or leaking equipment. Inspectors must, therefore, be
thoroughly familiar with VOC detector operating principles, calibration procedures,
operating problems, and leak screening techniques in order to perform both types of
inspections.
1.4 ORGANIZATION OF DOCUMENT
Chapter 2 - Applicability
The focus of this chapter is to address applicability determinations needed to
ensure the correct rule(s) is (are) being complied with, all appropriate components are
included in the program, and all such components are correctly identified as to which
service they are in.
Chapter 3 - Compliance/Inspection Through Reports and Recordkeeping
This chapter addresses the review of reports and recordkeeping for compliance
with the Federal equipment leak regulations.

Chapter 4 - Compliance/Inspection Through Walk-Through Monitoring
This chapter addresses the compliance and inspection issues that can be
addressed by conducting an actual walk-through of the facility including on-site review
of records and the use of a monitor during the walk-through.
Chapter 5 - Recommended Inspection Techniques and Procedures
This chapter provides a summary of the pros and cons of both enforcement
strategies. Actual programs should seek a balance between the two. The best
procedure will vary based on resources available to the inspector and the air quality
priorities of the regions.

CHAPTER 2
APPLICABILITY
This chapter addresses three critical applicability determinations. The first
determination is to ensure the correct rales are being complied with at any given
facility. Second, once the correct rale is determined for each process area within a
facility, determine whether all appropriate components have been identified. The third
critical determination is to ensure that these components are properly classified as to
what type of service they are in.
These three determinations are discussed in the following sections of this
chapter. For each determination, a discussion of each regulation is presented, followed
by a discussion of procedures that can be used in making these critical determinations.
2.1 WHICH REGULATION?
2.1.1 Specific Regulations
At many chemical manufacturing facilities, more than one Federal equipment
leak rule may be applicable to different pieces of equipment or process areas within the
facility. However, each rule has a precedence ranking relative to the other rales such
that only one rule should be applicable to any specific piece of equipment or process
area.
The HON standard (40 CFR 63, Subpart H and I) is the best place to begin for
the determination of rule precedence. The rale takes precedence over any equipment
also subject to NSPS or NESHAP standards, including some equipment previously
subject to benzene regulations. If a process is not subject to 40 CFR 63, it should be
reviewed for benzene applicability (40 CFR 61, Subparts J and V). The NESHAPs
take precedence over any applicable NSPS [§61.110(d) or §61.240(c)].
Several terms important to determination of rale applicability can be confusing
because they have different meanings under some of the rales (e.g., affected facility) or
can be used in different contexts (in service). Those terms important to the following
discussions are reviewed here to help clarify how the standards are applied.
2-1
-------
Affected Facility. An affected facility is an emission source or group of
emission sources to which a standard applies. Part 60, Subpart W defines affected
facility as the "group of all equipment within a process unit." All of the other rules
addressed by this manual define each individual piece of equipment (e.g., pump,
compressor) as the affected facility.
Process Unit. All of the standards (except RCRA Subpart BB) contain the
following generic definition: "a process unit can operate independently if supplied with
sufficient storage facilities for the product." Each standard also contains specific
qualifiers (see Table 2.1). The RCRA definition of a hazardous waste management unit
refers to the area hi which a nazardous waste is stored or in which constituent wastes
are mixed.
Table 2.1. Process Unit Definitions-Specific Qualifiers
Standard Specific Process Unit Definition
40 CFR Part 60 Components assembled to produce, as intermediate or final products, one or
more of the chemicals listed in §60.489 of Subpart W.
40 CFR Part 61 Equipment assembled to produce VHAP or its derivatives as intermediates or
final products, or equipment assembled to use a VHAP in the production of a
product.
40 CFR Part 63 Equipment assembled and connected by pipes or ducts to process raw materials
and to manufacture an intended product.
40 CFR Part 265 A contiguous area of land on or in which hazardous waste is placed, or the
largest area in which there is significant likelihood of mixing hazardous waste
constituents in the same area. Example; A tank and its associated piping and
underlying containment system.
The EPA clarifies the definition of process unit for the SOCMI standards, as
follows: The definition was drafted by EPA to provide a practical way to determine
which equipment is included in an affected facility. There are no specific physical
boundaries or size criteria. The definition instead depends upon several operational
factors, including chemical produced and the configuration of the processing
equipment. Such configurations may be different for different producers of the same
chemical; therefore, the definition may be fairly site specific. In practice, however, the
definition wiE implement the selection of a process unit basis as the "source" covered
by the standards.
Service. Service refers to two district concepts. "In ... service" addresses the
specific conditions by which rale applicability is determined. These terms (in organic
HAP service, in volatile organic compound (VOC) service, etc.) are discussed in this
section. "Type of service" refers to the physical condition of the process material:
gas/vapor, light liquid, or heavy liquid. Type of service is discussed in a later section
of this chapter.
2-2
-------
2.1.1.1 40 CFR Part 63
Within the chemical industry, the HON applies to major sources which
manufacture as a primary product one or more of a designated list of chemicals and
which make or use as a reactant or manufacture as a product, co-product, or byproduct
any of a designated list of organic HAPs, The applicable chemicals and HAPs are
published as Table 1 and Table 2 of 40 CFR 63, Subpart F.
In addition to the chemical manufacturing processes referred to above, the HON
also applies to a number of processes that produce certain butadiene-, chlorine-, or
styrene-based products. These processes are identified in 40 CFR 63, Subpart I, and
are required to comply with the provisions of Subpart H,
For those facilities subject to the HON, the standards apply to equipment in
organic hazardous air pollutant service for 300 or more hours per year. "In organic
HAP service" means that the equipment contains or contacts a fluid that is five percent
or greater by weight of total organic HAP. Within the rule, specific standards apply to
equipment in different types of service: gas/vapor, light liquid, and heavy liquid.
The HON also stipulates that each piece of equipment within a process unit that
can reasonably be expected to contain equipment in organic HAP service is presumed to
be in organic HAP service unless an owner or operator demonstrates that the piece of
equipment is not in organic HAP service. For a piece of equipment to be considered
not in organic HAP service, it must be determined that the percent organic HAP
content can be reasonably expected not to exceed five percent by weight on an annual
average basis. For purposes of detennining the percent organic HAP content of the
process fluid that is contained in or contacts equipment, Method 18 of 40 CFR Part 60,
Appendix A is to be used.
The HON is applicable to both new and existing facilities, regardless of their
date of construction. For the purpose of establishing compliance deadlines, those
processes subject to Subpart H are divided into five distinct groups. The compliance
dates (as of April 10, 1995) for the process groups at existing sources are as follows:
Group I: October 24, 1994
Group H: January 23, 1995
Group ffl: April 24, 1995
Group IV: July 24, 1995
Group V: October 23, 1995
2-3
-------
The group designation for each process unit is indicated in Table 1 of Subpart F.
However, the owner/operator of a plant has the option to comply at an earlier date than
required by the schedule.
New sources that commence construction or reconstruction after December 31,
1992, should be in compliance with Subpart H upon initial startup or April 22, 1994,
whichever is later.
Existing sources identified in Subpart I were required to comply with the
standard no later than October 24, 1994. New sources are required to comply upon
initial start-up.
Finally, any equipment that is in vacuum service and equipment that is in
organic HAP service less than 300 hours per year are excluded from the requirements
of the HON standard. No other specific exemptions are identified in the rule.
Equipment in VHAP service less than 300 hours per year as well as exempt equipment
in vacuum service must be identified in plant records.
2.1.1.2 40 CFR Part 61
The benzene equipment leak standards apply to components that are intended to
operate in benzene service. This is defined as "a piece of equipment which either
contains or contacts a fluid Qiquid or gas) that is at least 10 percent benzene by
weight." Generic provisions and standards for equipment in VHAP service are'at 40
CFR 61 Subpart V, and the benzene standards are at 40 CFR 61 Subpart J.
As with the HON, the benzene equipment leak standards apply to both new and
existing sources, and no applicability date separates new from existing sources. Each
piece of equipment within a process unit that can conceivably contain equipment in
VHAP service is presumed to be VHAP service unless an owner or operator
demonstrates that the piece of equipment is not in VHAP service. A piece of
equipment is considered to be not in VHAP service if the percent VHAP content can be
reasonably expected never to exceed 10 percent by weight. Such determinations can be
made through the use of engineering judgement or by following procedures that
conform to ASTM Method D-2267.
These standards do not apply to sources located in coke by-product plants. Any
equipment in benzene service located at a plant site designed to produce or use less than
1,000 mg of benzene per year is exempt from the benzene NESHAP. This cutoff is
intended to exempt most research and development facilities and other small-scale
operations. Also exempt is any process unit that has no equipment in benzene service
and any equipment that is in vacuum service. All exempt equipment and equipment not
in VHAP service must be identified in plant records.
2-4
-------
2.1.1.3 40 CFR Part 60
SOCMI is a broad source category that covers plants that produce many types of
organic chemicals. Examples of organic chemicals produced in the SOCMI segment
include acetone, methyl methacrylate, toluene, and glycine. The complete list of
organic chemicals covered by SOCMI equipment leak standards is found in §60.489 of
40 CFR Part 60. 40 CFR 60 Subpart W applies to the industries that produce as
intermediates, byproducts, or final products, one or more of the chemicals listed in
§60.489 of the standard. The standards apply to any affected facility that commenced
construction or modification after January 5, 1981.
Subpart W applies to any piece of equipment which contains or contacts a
process fluid that is at least 10 percent VOC by weight.
Any affected facility that has the design capacity to produce less than 1,000
megagrams (Mg) (1,100 tons) per year is exempt from the SOCMI rules. An affected
facility that produces heavy liquid chemicals only from heavy liquid feed or raw
materials is also exempt. Exemptions also apply to: any affected facility that produces
beverage alcohol, any affected facility that has no equipment in VOC service, and all
equipment in vacuum service.
2.1.1.4 40 CFR Part 264 and 265
40 CFR Part 264, Subpart BB applies to owners and operators of facilities that
treat, store, or dispose of hazardous wastes (TSDFs). Part 265, Subpart BB applies to
owners and operators of interim status TSDFs. These subparts apply to equipment that
contains or contacts hazardous wastes with organic concentrations of at least 10 per cent
by weight that are managed in: (1) units that are subject to the permitting requirements
of 40 CFR Part 270, or (2) hazardous waste recycling units that are located on
hazardous waste management facilities otherwise subject to the permitting requirements
of Part 270, A facility may be an operational chemical manufacturer, but any organic
waste streams it generates may render it subject to 264/265 BB (i.e., it does not need to
be a commercial treatment, storage, or disposal facility).
Any equipment that is in vacuum service is excluded from the requirements of
this standard. However, equipment in vacuum service must be identified in plant
records. These regulations do not affect conditionally-exempt or small-quantity
generators, and they do not affect satellite accumulation areas.
2.1.2 Procedures to Determine if Appropriate Rule is Being Applied
Determination of rule applicability is ultimately the responsibility of the
regulated facility. Normally, any questions regarding applicability are reviewed and
2-5
-------
resolved through the State permitting process. Thus, an inspector can determine which
rules are being applied to a facility by consulting that facility's air permits. However,
permits are not always correct, and total reliance on the permit is not recommended. A
thorough knowledge and understanding of the various process areas within a facility,
and the relationship of such processes to potentially applicable rules, will contribute to
an inspector's effectiveness.
At any given facility, there will be an ongoing activity of equipment replacement
or retirement and additions or modifications to the various processes. Good process
knowledge will help the inspector to keep track of such changes, understand how the
current rule applies to new equipment, and identify any oversights by the facility in the
identification of such equipment. Additionally, the inspector may identify situations
such as changes to process constituents or formula, or major modifications, which
necessitate a review of rule applicability. With experience, the inspector may be able
to identify entire processes or facilities which an owner/operator has failed to recognize
as potentially subject to a rule.
2.2 WHICH COMPONENTS?
2.2.1 Specific Components
Each of the Federal equipment leak regulations specifies a list of components
covered by each regulation. Specific components common to all of the regulations
include: valves, connectors, pumps, compressors, pressure relief devices, sampling
connection systems, open-ended valves or lines, and closed vent systems and control
devices. The benzene NESHAP also applies to product accumulator vessels, whereas
the HON also applies to agitators, surge control vessels, bottoms receivers, and
instrumentation systems.
2.2.2 Quiflance tqi Determine if Eqm|tment Jas Been Identified Properly
Production facilities subject to one or more of the equipment leak standards are
typically large plants with a very large number of components. In order to comply with
the various standards, an owner or operator needs to be able to locate and identify those
components subject to the standards and to reference any relevant information
applicable to each individual component. Some types of information are required by
some of the rules; other information is simply useful or prudent from the
owner/operator's perspective. An inspector should develop a detailed understanding of
a facility's component identification system, as well as information about the
components themselves.
2-6
-------
The most basic element of any component identification system is the
assignment of a unique identification (ID) number to each component. The ID number
is used to comply with various recordkeeping and reporting requirements. For
example, the ID number of each component that is found to be leaking is recorded in a
log. In addition, a list of the ID numbers of all equipment subject to the standards are
to be recorded in a log. Lists of identification numbers are also required for equipment
in vacuum service, and other equipment in any special status identified by the
regulations.
Following establishment of an ID system, being able to establish the exact
location of each component is the next basic element. Most ID systems are designed to
facilitate location by incorporating the individual process unit (or other geographically
convenient criteria) into the number system. For the NSPS equipment leak standards,
components are only subject to the standards if they are located in an affected facility.
Therefore, it is important to identify the location of each component with regard to the
process unit it is in and whether that process unit is an affected facility.
Another item of concern to the inspector is the relationship between the plant's
inventory of equipment subject to the standards and the equipment which is actually in
service. When individual pieces of equipment or subsections of a process area are
taken out of service, such equipment should be routinely retired or identified as out-of-
service on the inventory. Likewise, new or replacement equipment should be added to
the inventory. If an inspector can identify equipment that has not been properly added
or deleted from the inventory, then the facility may not be in full compliance with the
applicable rule.
2.3 WHICH SERVICE?
2.3.1 Service Definition
The specific standards applied to equipment subject to these rules depends on
the type of service the equipment is in. Most rules identify three types of conditions:
gas/vapor service, light liquid service, and heavy liquid service. Part 61 does not
define "light" or "heavy" liquid, just "liquid service." Definitions of the three types of
service are the same, although several rules provide for alternative means of
measurement or demonstration.
"In gas/vapor service" means that the piece of equipment contains or contacts
process fluid that is in the gaseous state at operating conditions. All of the standards
use this definition except the HON, which refers to "equipment in organic hazardous air
pollutant service (which) contains a gas or vapor at operating conditions."
2-7
-------
Equipment Is "in light liquid service" if all of the following conditions are met:
• The vapor pressure of one or more components is > 0.3 kPa (0,04 psi) at
20°C.
• The total concentration of the pure components, with a vapor pressure
>0,3 kPa (0.04 psi) at 20°C, is s20 percent by weight.
* The fluid is a liquid at operating conditions.
40 CFR Part 61, Subpart V defines "in liquid service" rather than differentiating
between "in light liquid service" and "in heavy liquid service." In liquid service means
that a piece of equipment is not in gas/vapor service. The HON also uses this
definition of "in liquid service."
A summary of components and type of service designations covered by the
Federal equipment leak regulations is presented in Table 2.2.
2.3.2 Guidance toJMermtne if Correct Seryjce is Identified
As is the case with rule applicability, determination of type of service is the
responsibility of the regulated facility. The regulations require that documentation of
type of service determination be maintained by the facility. If an inspector questions a
facility's classification, a review of the records which address how the type of service
classification was made would be the first step.
An inspector may also be able to review process and material balance data to
determine if type of service classifications are appropriate. As a final course of action,
an inspection may collect a sample of the process material in question and apply the
analysis specified by the applicable rule.

CHAPTERS
COMPLIANCE/INSPECTION THROUGH
REPORTS AND RECORDKEEPING
It is extremely important that an inspector be thoroughly familiar with the
reporting and recordkeeping requirements of the regulations. With the exception of
RCRA, all of the equipment leak standards addressed by this manual stipulate that
compliance with the applicable standards will be determined by review of required
records, by review of performance test results, and by inspections. The NSPS and
HON also reference reports as a basis for compliance demonstration. Parts 264 and
265 both specify reeordkeeping requirements, and Part 264 requires reports if leak
repairs are not completed on schedule or if control devices deviate from their
operational standards for more than 24 hours. Review of reports and records is also a
critical component in the conduct of effective on-site inspections.
This chapter first addresses the content of required reports for the NSPS,
NESHAP and HON and discusses their review for the purposes of compliance
determination. Recordkeeping requirements of the NSPS, NESHAP, HON, and RCRA
regulations are then addressed, with a concluding discussion of recordkeeping
compliance reviews. The chapter concludes with additional discussion of strategies an
inspector can use to supplement the review of records and reports. Chapter 4 addresses
the role of records and reports as a resource for on-site inspections.
3.1 REPORTS
3.1.1 40 CFR Part 60. Subpart W
Facilities subject to Subpart W are required to submit reports both under the
general provisions, which are applicable to all NSPSs unless the specific subpart says
otherwise, and under Subpart W. The following paragraphs identify the various
reports required and the information each is to contain. Failure to submit the required
reports on time and with the required information may be grounds for non-compliance.
The NSPS General Provisions (40 CFR Part 60, Subpart A, §60.7) mandate that
any owner or operator subject to a NSPS must provide written notification of the date
3-1
-------
of construction or reconstruction within 30 days after work begins. In addition to the
construction or reconstruction notification, the general provisions require the following:
• A notification of the anticipated date of initial startup of an affected
facility postmarked between 30 and 60 days before the startup date.
» A notification of the actual date of initial startup of an effective facility
within 15 days after startup.
• A notification of any physical or operational change to an existing
facility that may increase the emission rate of any pollutant to which a
standard applies, unless that change is specifically exempted. This
notice shall be postmarked 60 days, or as soon as practicable, before the
change.
3.1.1.1 Initial Reports
Under Subpart W facilities are required to submit semiannual reports beginning
six months after the initial startup date and every six months thereafter. The initial
report must include an identification of the process unit, the number of valves in
gas/vapor service or light liquid service, the number of pumps in light liquid service,
and the number of compressors. Valves, pumps, and compressors that are designated
as having no detectable emissions should not be included hi the totals listed in the initial
report.
3.1.1.2 Semiannual Reports
Semiannual reports are required beginning six months after the initial report and
each six months thereafter. These reports contain information on the results of LDAR
programs. The information required in these reports begins with the process unit
identification, which should correspond with the identification in the initial report. The
semiannual report must document, on a monthly basis, the total number of detected
leaks and the number of this total that were not repaired in the required 15-day period.
In each Distance where a repair is delayed, the report is to explain the delay. If the
reason for the delay is that it could not be repaired until a process unit shutdown, then
the report is to indicate why a process unit shutdown was technically infeasible during
the reporting period. The report shall then show the dates during the reporting period
when process unit shutdowns occurred. In addition, any revisions to items reported in
the initial report are to be described and discussed. The format of reports is not
specified in the regulations, and a number of variations are acceptable.
3-2
-------
3.1.1.3 Other Reporting Requirements
Other reporting requirements contained in the NSPS regulations include two
alternative standards for valves: the allowable percentage of valves leaking, and the
skip-period LDAR program. If an owner or operator elects to comply with either of
these alternative standards, a notification must be provided 90 days before
implementing the provisions.
40 CFR Part 60 also requires the owner or operator to submit a written report of
the results of any performance test to EPA. Performance tests are required for no
detectable emissions equipment and valves complying with an alternative standard.
They also may be required for closed-vent systems, control devices, and equivalent
means of emission limitation. Information must be made available to EPA as necessary
to determine the operating conditions during the performance tests. In addition,
Subpart W requires that the owner or operator notify the Administrator of the schedule
for the initial performance tests at least 30 days before conducting them.
3.1.2 40 CFR Part 61
40 CFR Part 61, Subparts J and V require submission of an initial statement and
semiannual reports.
3.1.2.1 Initial Reports
The initial report must contain two portions: a written assertion stating that the
company will implement the standards and the testing, reeordkeeping, and reporting
requirements contained in the applicable NESHAP; and information on the equipment
subject to the regulation, including equipment identification (ID) numbers, process unit
IDs for each source, and a description of the type of equipment (e.g., a pump or a
pipeline valve). Also, the percent by weight of VHAPs in the fluid being handled by
the equipment and the state of the fluid (i.e., gas/vapor or liquid) must be included.
Finally, the initial report must contain a description of the chosen method of
compliance and a schedule for subsequent semiannual reports. The source must abide
by this schedule unless it is amended in subsequent semiannual reports.
All facilities in existence on the effective date of any NESHAP were required to
submit an initial report. Therefore, all existing facilities subject to the above-
referenced standards should have already submitted an initial report. All new plants are
required to submit an initial report with the application for approval of construction, as
required by the general provisions of Part 61 (NESHAP).
3-3
-------
3.1.2.2 Semiannual Reports
Six months after the initial report, and every six months thereafter, the facility
must submit a semiannual report. These semiannual reports are for NESHAP
compliance and are similar to the required NSPS semiannual reports. They must
provide process unit IDs for regulated equipment and, on a monthly basis for each
process unit, the number of valves, compressors, and pumps that were detected leaking.
Of those valves, compressors, and pumps that were detected leaking, the number that
were not repaired within 15 days is to be reported, along with an explanation of why a
repair was delayed. If the reason for the delay was that a process unit shutdown is
needed before repair, then an explanation must be given why a process unit shutdown
was infeasible.
The report also must include the dates of all process unit shutdowns during the
six-month reporting period and a discussion of any revisions to the initial report or
subsequent revisions to the initial report. The regulations do not specify the format of
the reports; they only specify minimum content requirements. Each facility develops
and uses its own format.
These standards allow the designation of equipment subject to a no detectable
emissions limit rather than an LDAR standard, an alternative standard based on the
allowable percentage of valves leaking, and an alternative skip-period LDAR program.
All three of these as well as closed-vent systems and control devices require
performance tests. If a performance test was conducted within the six-month reporting
period, then the results of the test also must be included in the semiannual report.
3.1.2.3 Other Reporting Requirements
An owner or operator of a facility electing to comply with either of the
alternative standards for valves (i.e., the allowable percentage of valves leaking or the
skip-period LDAR program), must provide notification 90 days before implementation
of either of these programs.
Certain circumstances described in the regulations do not require an application
for approval of construction/modification. These circumstances are: (1) a new source
complies with the standards, (2) a new source is not part of the construction of a
process unit, or (3) all information required in the initial report is contained in the next
semiannual report.
3.1.3 40 CFR Part 63. Subparts H and I
Existing facilities subject to the HON standards are required to submit an initial
notification that describes the source and the chemical manufacturing processes subject
3-4
-------
to the standards. New sources (if the start-up date is 90 days or more after the
promulgation date) are required to submit an application for approval of construction or
reconstruction in lieu of the initial notification. All sources are required to submit a
Notification of Compliance Status within 90 days of the applicable compliance date.
This notification describes how the source will maintain compliance with the standard.
Finally, periodic reports are to be submitted semiannually beginning six months after
the Notification of Compliance Status. Reports can be submitted on electronic media
where acceptable to the regulating agency and the owner/operator of the source.
3.1.3.1 Initial Notification
The initial notification required of existing sources is due within 120 days of the
date of promulgation of the applicable standard (April 22, 1994, for Subparts H and I).
It is to include the name and address of the owner or operator, the address (physical
location) of the affected source, identification of the chemical manufecturing processes
subject to the subpart, and a statement of whether the source can achieve compliance by
the applicable compliance date. The application for approval of construction or
reconstruction submitted by new sources is to contain the same information as required
for the initial notification.
3.1.3.2 Notification of Compliance Status
The Notification of Compliance Status is due within 90 days of the applicable
compliance date (Subpart H has five dates, see Chapter 1) for existing sources. New
sources, which are required to comply with Phase II of the HON upon initial startup,
would include the equivalent compliance status information in their application. The
Notification of Compliance Status requires the following information for each process
unit subject to the standards:
• Process unit identification
• Number of each equipment type (e.g., valves, pumps) excluding
equipment in vacuum service
• Method of compliance with the standard (e.g., "monthly LDAR" or
"equipped with dual mechanical seals")
• A planned schedule for each phase of the requirements applicable to
pumps in light liquid service and valves in gas/vapor or light liquid
service.
If a source elects to use pressure testing of batch product process equipment to
demonstrate compliance, the notification report is to include the batch products or
3-5
-------
product codes subject to this option and the planned schedule for pressure testing of the
equipment when it is configured for such production. The notification shall identify
each enclosed-vented process unit and describe the negative pressure system and control
device used.
3.1.3.3 Periodic Report
The periodic reports are to be submitted semiannually and are to convey the
following information for each process unit for each monitoring period during the six-
month period reported:
• The number (by type) of valves, pumps, compressors, agitators,
connectors, and screwed connectors that were detected leaking and the
number for which leaks were not repaired as required in the standard.
* The total number (by type) of valves, pumps, connectors, and screwed
connectors monitored and the percent of the total found leaking.
» The number of unrepaired valves and the number of unrepaired
connectors that are determined non-reparable.
• The facts that explain any delay of repairs and, where appropriate, why a
process unit shutdown was technically infeasible.
« The results of all monitoring of pressure relief devices, closed-vent
systems, and any compressors designated to operate at less than 500
ppm.
* If applicable, implementation of a monthly monitoring program for
valves, a quality improvement program for valves or pumps, or a change
in connector monitoring alternatives.
If the source has elected to use pressure testing to demonstrate compliance for
batch process equipment, the report shall also include;
* Batch product process equipment train identification.
» The number of pressure tests conducted and the number of tests where
the equipment train failed the test.
• The facts that explain any delay of repairs.
3-6
-------
• The results of all monitoring to determine compliance with standards for
closed-vent systems and control devices.
3.1.4 40 CFR Parts 264 and 265. Subpart BB
TSDF facilities to which Part 264 applies are not required to submit an initial
report and are required to submit a semiannual report only under certain conditions.
These conditions refer to failure to repair leaking equipment on schedule or failure to
correct a control device which exceeds or operates outside of design specifications. If a
report is required, it shall identify the facility and provide the dates of hazardous waste
management unit shutdowns that occurred during the preceding semiannual reporting
period. For each month during the semiannual reporting period, the TSDF is required
to report: (1) the ID number of each valve, pump, or compressor for which a leak was
not repaired or required, and 2) the date, duration and cause of any control device
exceedance, and any corrective measures taken.
40 CFR Part 265, Subpart BB contains no reporting requirements.
3.1.5 Reviewing Reports
Although reports are the primary mechanism by which a facility documents
compliance with the equipment leak rules, they are of limited value to the inspector as a
means of identifying specific violations or of substantiating noncompliance. From a
regulatory point of view, review of reports can only substantiate noncompliance on the
basis of:
» Failure to submit a report
• Late submittals
• Missing or incomplete report content
• Self-reported violations
For purposes of determining compliance, the primary focus of an inspector's
review of reports should be on the issue of report completeness. Other issues
(accuracy, equipment classification, monitoring performance, etc.) require some further
interaction with the review of records and/or on-site inspections.
During the first year or two of developing an equipment leak program at a
regulated facility, it is possible that a facility may overlook or be unaware of some
reporting requirements. Equipment subject to partial exemptions or non-routine
reporting schedules may be the most likely to be overlooked. However, once a facility
3-7
-------
has submitted a report that the Agency accepts as complete, the facility is unlikely to
regress from this established standard. Subsequent violations of reporting requirements
are most likely to be associated with changes in the process, e.g., failure to add/delete
equipment as a result of maintenance or process modifications.
A report may contain "self-reported" violations such as failure to attempt
equipment repair within schedule or during process shutdown. An inspector should, of
course, review each report carefully and note such "self-reported" violations for follow-
up. In many cases, these events prove to be recordkeeping or reporting errors rather
than true violations. For example, transcription errors may occur between records and
reports (e.g., a valve is monitored as leaking at 1,500 ppm but is transcribed to a report
at 15,000 ppm), or a maintenance crew may forget to submit repair invoices. By
routinely following up on such questions, an inspector will help the facility to recognize
inadequacies in its equipment leak compliance program and such reporting errors
should decline.
Many facilities employ sophisticated monitoring systems and databases to
minimize both the labor hours and opportunities for clerical errors associated with large
scale monitoring systems. Monitoring equipment can be equipped with a data logger
containing the sequential ID numbers for all equipment within a process area. At each
monitoring point, the data logger automatically records the highest instrument reading
obtained at that point. This data can then be downloaded to a database that contains;
(1) all the relevant information for each piece of equipment, and (2) a report generator
which automatically prepares the appropriate report for each process area.
Sophisticated systems can also generate erroneous reports, as a result of lack of
foresight in their preparation or due to a lack of human attention to the system. As an
example, some data logging systems employ a default value of zero or carry forward
the reading from the previous monitoring. As a result, these systems may report a
numerical reading for a piece of equipment, even if that equipment was not monitored.
Conversely, these systems may not be able to record readings from new equipment until
the equipment data has been entered into the database.
Ultimately, the best strategy for effective review of reports by an inspector is
developed familiarity. This includes familiarity with the recordkeeping and reporting
requirements of the rules, and familiarity with how the regulated facility is performing
its monitoring, data management, leak repair, and reporting programs. By developing
such detailed knowledge about a specific facility, an inspector will be better prepared to
interpret and understand that facility's reports. This developed familiarity requires an
ongoing balance of effort which includes on-site inspection and review of records.
3-8
-------
3.2 RECORDKEEPING
3.2.1 Part 60 Subpart W and Part 61 Subpart V & J
All of the equipment leak regulations require the maintenance of extensive,
detailed records that can be readily accessed at the plant site. Specific records that are
required include:
• A list of ID numbers for all equipment subject to the requirements
(except for welded fittings or connectors under some rules).
» A list of equipment ID numbers for equipment designated for "no
detectable emissions" or complying with the less than 500 ppm above
background standard. The no detectable emissions designation must be
signed by the owner or operator and requires an annual compliance test
and a record of the date of the compliance test, the background level
measured, and the maximum instrument reading measured at the
equipment.
• A list of equipment ID numbers for pressure relief devices required to
comply with the standards for pressure relief devices in gas/vapor
service.
» A list of ID numbers for equipment in vacuum service.
If a closed-vent system and a control device are used to control fugitive
emissions, the records for this equipment must include:
• Detailed schematics, design specifications, and piping and
instrumentation diagrams,
• Dates and descriptions of any changes in the design specifications.
» A description of the parameters) monitored to ensure that a control
device is operated and maintained in conformance with the design, and
an explanation of why that parameter was selected for monitoring.
• Periods when the closed-vent systems and control devices are not
operated as designed, including periods when a flare pilot light does not
have a flame.
• Dates of start-ups and shutdowns of the closed-vent systems and control
devices.
3-9
-------
A dual mechanical seal system that includes a barrier fluid system is an
alternative for reducing emissions from pumps and compressors. If a dual mechanical
seal system with a barrier fluid system is used, the following information must be
recorded: (1) the design criteria that indicates failure of the seal system, the barrier
fluid system, or both; (2) an explanation of the choice of this design criteria; and (3)
documentation of any changes to the criteria and the reasons for the changes.
The records also must contain a list of ID numbers for valves that are designated
as "unsafe to monitor," an explanation for this designation, and the plan for monitoring
each valve. The same records are required for valves designated as "difficult to
monitor." For valves complying with the skip-period provisions, a schedule of
monitoring and a record of the percent of valves found leaking during each monitoring
period must be kept on file.
Certain criteria allow a facility to be exempted from the requirements (see
Chapter 2). If a facility claims an exemption, then it must maintain a log that contains
information, data, and analyses to support its exemption declaration. For example, 40
CFR 63 Subparts V & J stipulate that the following information shall be recorded: (1)
an analysis demonstrating the design capacity of the process unit, and (2) an analysis
demonstrating that equipment is not in VHAP service.
For each compliance monitoring test conducted, a record of results must be
retained. This includes the monthly leak monitoring for pumps and valves, as well as
the annual no detectable emissions monitoring for pumps, compressors,'valves, and
closed-vent systems. Any monitoring for alternative standards also must be
documented.
Other non-periodic circumstances require compliance monitoring. A pressure
relief device must be monitored within five calendar days after a pressure release to
confirm that no emissions are detectable. If a pump or valve in heavy liquid service,
flange, or other connector is suspected of leaking, this equipment must be monitored
within five days. If a leak is detected and repair is attempted, the component must be
monitored to determine if the repair attempt was successful. Records must be kept of
the findings of all such monitoring tests. If a leak is detected, the equipment must be
identified as a leaking component by attaching an ID tag to the leaking equipment. The
tag must be weatherproof and readily visible. A tag may be removed after the
equipment has been repaired and retested successfully. The tag may be removed from a
valve, however, only after it has been repaired and monitored for two successive
months with no detected leak.
When leaks are detected, records on each leak must be kept and maintained for
two years. For each detected leak, the equipment ED number, the instrument and
operator ID numbers, and the date the leak was detected must be recorded. The date of
3-10
-------
each repair attempt and an explanation of each method applied should be recorded. If
the leak is corrected, then the date of successful repair should be entered in the log. If
the repair is unsuccessful, the operator should record that the maximum instrument
reading of the monitoring after the respective repair was above the applicable leak
limit.
If a leak is not repaired within 15 calendar days of being detected, "repair
delayed" should be entered in the log, and the reason for the delay should be discussed.
If the reason for the delay is that the repair could not be attempted until a process
shutdown, then the person who made the decision to delay repair must sign the log. If
process unit shutdowns occurred while the leak remained unrepaired, the dates of these
shutdowns also must be recorded. Finally, the expected date of successful repair of the
leak should be entered for these delinquent leaks.
3.2.2 Recordkeeping for the HON
The HON incorporates virtually all of the recordkeeping requirements of the
NSPS and NESHAP standards, with significant additions and extensions. For example,
all equipment ID numbers are required to identify the process area in which the
equipment is located. Additional equipment addressed by the HON includes agitators,
product accumulator vessels, and bottoms receivers equipped with closed-vent and
control systems, pressure release devices equipped with upstream rupture disks,
instrumentation systems, batch process equipment, enclosed-unit processes, and
equipment in HAP service less man 300 hours per year. Substantial new recordkeeping
requirements are associated with equipment in a quality improvement program (QDP).
Connectors need not be identified individually, but the number of connectors in
each process area are to be recorded. Screwed connectors are to be individually
identified. Additionally, each connector which has been disturbed since the last
monitoring is to be identified and the date and result of follow-up monitoring recorded.
The HON records require a monitoring schedule by process area for valves and
connectors. Both valves and connectors that are designated as difficult to monitor,
unsafe to monitor, or unsafe to repair are to be identified in the records. The records
must also ID valves and connectors which have been removed from service and claimed
for emission reduction credits.
Tagging of individual components within each process area is not required by
the HON, so long as other identification requirements are met. Tagging and reporting
requirements for leaking equipment are the same as the NESHAP regulations. For
equipment which cannot be repaired within the applicable deadline, the HON allows
written procedures for determining that such equipment qualifies for delay of repair
status to be included hi the records.
3-11
-------
Visual inspections required by the HON are to be recorded. These are to
include documentation that the inspection was conducted, the date of the inspection, and
detailed records for leaking equipment identified in these inspections.
When a facility elects to periodically pressure test a batch process, each
regulated product and the time hi service for each product are to be recorded. Pressure
test records are to include the date of each test and any visual observation of leaks.
When equipment fails a pressure test, records are to be kept of each leak repair attempt,
the date of each repair, the repair methods employed, and the reasons for any delay of
repair.
Enclosed-vent process units and the HAPs they handle are required to be
identified in the records. Enclosed-vent process units are enclosed in such a manner
that all emissions from equipment leaks are vented through a closed vent system to a
control device. The records are to include a schematic of the process unit, enclosure,
and closed vent system and a description of the system used to create the negative
pressure in the enclosure.
A QIP generally consists of information gathering, detennining superior
technologies, and replacing existing equipment with the superior technologies until the
required base performance levels are achieved. The recordkeeping requirements
basically stipulate dates and documentation of QIP activities. The Demonstration of
Further Progress QIP for valves requires additional recordkeeping for monitoring and
repair activities. The Technology Review and Improvement QIP for valves or pumps
extends recordkeeping requirements to include: equipment construction and use data,
process stream data, inspection of leaking valves removed from service or of pumps
that leak frequently, and analysis of equipment performance based on these records.
3.2.3 RCRA Recordkeeping Requirements
The RCRA equipment leak standards stipulate that records be maintained hi the
facility operating record or in a log maintained in the facility operating record. The
following information is to be maintained for each piece of equipment to which Subpart
BB applies:
• Equipment ID number and hazardous waste management unit
identification.
• Approximate location within the facility.
• Type of equipment (e.g. pump or pipeline valve).
3-12
-------
• Percent-by-weight total organics in the hazardous waste stream at the
equipment.
» Physical state of hazardous waste at the equipment (e.g., gas/vapor or
liquid).
* Method of compliance with the standard.
» A list of ID numbers for all subject equipment.
» A list of ID numbers for equipment designated for "no detectible
emissions," with signature of the owner or operator.
• A list of ID numbers for pressure relief devices subject to the standard.
» For each compliance test required by the standards, the date, the
background level, and the maximum instrument reading measured at the
equipment.
For each leak detected in the compliance tests, the following information is to be
recorded in a log and maintained for three years:
• The instrument, operator, and equipment ID numbers.
• The date evidence of a potential leak was found.
« The date the leak was detected and the dates of each repair attempt.
» Repair methods applied in each attempted repair.
* "Above 10,000" if the instrument reading following a repair attempt
exceeds 10,000 ppm.
• "Repair delayed" and the reason if a leak is not repaired within 15 days
of discovery.
• Delay of repair documentation for applicable valves.
* Owner or operator signature when repairs cannot be effected without a
unit shutdown.
• The expected date of repair for leaks not repaired within 15 days.
3-13
-------
• The date of successful repair.
The records are to include design documentation and monitoring, operating, and
inspection information for each closed vent system and control device. In addition, a
performance test plan and documentation of performance test results are required when
test data is used to demonstrate control device performance. Control devices not
otherwise identified in the regulations are also required to record monitoring and
inspection information indicating proper operation and maintenance of the control
device.
A list of valves designated as unsafe to monitor and a list of valves designated as
difficult to monitor are to be maintained. Each list is to include an explanation of the
designation and a plan for monitoring each valve. Recorded information for other
valves must include (1) a schedule of monitoring and (2) the percent of valves found
leaking during each monitoring period.
The following information is to be maintained hi a log for determination of
applicable exemptions: (1) analysis determining the design capacity of the hazardous
waste management unit, (2) a statement listing the hazardous waste influent/effluent to
each unit and an analysis determining whether these hazardous wastes are heavy
liquids, and (3) up-to-date analysis, supporting information, and data used to determine
applicability of the standards.
3.2.4 Reviewing Records
When reviewing equipment leak records, it is important to keep in mind the
primary purpose of the records, which is verification of the information in the reports
and documentation of other elements of program performance such as performance of
monitoring, adherence to repair schedules, documentation of visual inspections, etc.
Review of records should be guided by the inspector's prior review of the reports and
should focus on using the records to (1) confirm the accuracy and content of the reports
and (2) determine that recordkeeping requirements of the applicable standard are
complied with.
Specifically, records should be investigated to confirm that all components are
indicated as being monitored as reported and to confirm the number of reported leaks.
Additionally, such information should be compared with the inventories of total
components by type of service as recorded in the initial report for each facility. There
will normally be some fluctuation in the total number of components inspected during
each monitoring period due to a variety of factors such as leak/repair status and
equipment retired from or added to a process. A detailed review of the records may be
necessary to resolve all of the apparent anomalies in process areas with a large number
3-14
-------
of components or where substantial modifications are underway. Failure to record and
report such changes may result in a violation of the standards.
Records should also be reviewed to confirm the performance of repairs and
follow-up monitoring on all reported leaks. For example, if a valve was reported
leaking, check if the records confirm the following: (1) a first attempt to repair within
five days, (2) completion of repair within 15 days, and (3) monthly monitoring for two
months before return to quarterly monitoring. If the valve was not repaired but was
scheduled for repair at the next shutdown, was this an appropriate classification (i.e. is
the explanation/documentation of the classification reasonable and signed by the proper
official)? The complete list of components scheduled for repair at the next shutdown
should be reviewed to determine the appropriateness of this classification.
As is the case with reports, only a limited number of specific violations can be
identified and confirmed solely through a review of records. Establishing such a
violation is primarily a process of identifying something which is missing. Facilities
are in direct noncompliance under the following situations:
• Failure to record leaks and dates of repairs,
• Failure to record the reason for delaying repair of leaks past an allotted
tune frame,
• Failure to develop a schedule to observe visual emissions from flares,
» Failure to perform emission testing for control devices (except in the
case of flares), and
• Failure to record periods when the control device is not operating.
Finally, each facility will develop and implement its own form of
recordkeeping. The variety and inconsistency of recordkeeping formats from one
facility to another is a problem which an inspector has little opportunity to influence or
correct. For example, the availability and utility of work orders to support
recordkeeping or to confirm/resolve errors and oversights will vary from facility to
facility. To be effective, an inspector needs to develop a degree of familiarity with the
data collection and management system of each facility in his or her area of
responsibility.
3-15
-------
3.3 STRATEGIES FOR REVIEWING REPORTS AND RECORDS
As has been previously discussed, the report and recordkeeping requirements of
the equipment leak regulation do. not provide enough information for an inspector to
make a complete determination of compliance. The report and recordkeeping review
activities provide the basis for determining whether a facility is in compliance with the
report and recordkeeping requirements and provide the informational basis for more in
depth inspection activities. Strategies available to the inspector to improve the
effectiveness of both functions include (1) requesting additional information and 2)
coordinating the review process with on-site inspections to reinforce the determination
of compliance.
An inspector can generally request that a facility provide any records specified
by the equipment leak regulations in the form of a supplementary report. A thorough
understanding of the records required by the standards and the data management
systems of the individual facilities will enable an inspector to request additional
information in a format that is reasonable for the facility to comply with and useful to
the inspector's objectives. Other information not specifically referenced in the
regulations may also be available to the inspector. Process flow diagrams and/or
schematics of individual process areas can be particularly useful as a means of orienting
oneself prior to a site visit, reviewing the appropriateness of various equipment
designations (e.g., type of service, dangerous to monitor), and for cross-referencing
data from various records sources. Work repair orders and/or repair invoices are
another source of potentially useful information, especially when it is necessary to
reconcile apparent gaps or oversights in the records.
Required reports and supplementary irformation provided by the facility are
useful means of preparing for on-site inspections. In addition, information collected
on-site or requested during a site visit can be used for follow-up review and evaluation
of compliance status. Collecting or requesting information for review after completion
of a site visit allows the inspector to make more efficient use of available time while on-
site. Such information can be used to supplement and/or document inspection field
notes and observations. Additionally, such information can be compared with the
initial review of semiannual reports to resolve any lingering questions.
3-16

CHAPTER 4
COMPLIANCE/ASSESSMENT THROUGH ON-SITE INSPECTIONS
On-site inspections are a critical component in evaluating compliance with the
leak detection rules and evaluating the effectiveness of facility LDAR monitoring
activities. Due to the complexity of the standards and the large numbers of emission
points at a typical facility, it is imperative that an inspection be conducted hi a
systematic fashion. An inspector may choose to use a portable VOC analyzer to
conduct direct leak checks of regulated equipment, but it is also possible to conduct a
compliance inspection without the use of such equipment. The first portion of this
chapter addresses the conduct of a walk-through inspection without an analyzer; the
second portion addresses the conduct of inspections with the direct monitoring of
regulated equipment.
Equipment leak inspections encompass a broad range of potential activities. The
specific content and organization of inspections will vary according to the priorities or
objectives of the inspector and/or policies of the agency. For example, it may be
necessary to devote an entire inspection to on-site interviews and examination of
records addressing the appropriate classification of equipment. Short, follow-up
inspections may be combined with other on-site activities. This chapter uses a
simplified inspection format to illustrate the important elements of organizing and
conducting inspections.
4.1 WALK-THROUGH INSPECTIONS
A complete equipment leak inspection program includes pre-inspection
activities, on-site activities, and post-inspection review and reports. The pre-inspection
activities help the inspector become familiar with the facility, contributes to the
selection of specific process areas or components to be inspected, and may determine
the actual timing of the inspection. On-site activities include review of records,
interviews with plant personnel, inspection of regulated equipment, and observation of
monitoring procedures. Post-inspection activities include additional review of records
and other information, preparation of the inspection report, and establishing the
foundation for subsequent inspections.
4-1
-------
4.1.1 Pre-inspection Activities
The purpose of pre-inspection activities is for the inspector to develop a general
understanding of the plant under investigation, the processes employed, and products
produced. Additionally, the inspector should be familiar with the applicable regulations
and understand what types of information are required to determine compliance prior to
the on-site inspection. Good preparation helps to select those units suspected or
detected as being compliance problems, determine the appropriate timing of the
inspection, and improve an inspector's efficiency while on-site. Caution: While it is
meaningful to gain an impression of the overall situation through these pre-
inspection activities, it is equally important than an inspector not prejudge a
facility based only on the preliminary information. Compliance determination
should be finalized only after the on-site inspection and follow-up activities are
completed.
It is important that the inspector keep detailed records for each inspection. An
inspection notebook should be started during the pre-inspection time period so that all
information is contained in a central location for the entire inspection. Since the
notebook may be used to form the premise of the inspector's report and as evidence in
legal proceedings, it is critical that the inspector substantiate the facts with tangible
evidence such as pertinent observations, photographs, copies of documents,
descriptions of procedures, unusual conditions, problems and statements from facility
personnel.
4.1.1.1 Report Reviews and Other Information Sources
Sources subject to the various equipment leak standards are required to submit a
preliminary notification and/or initial report which provides general facility
information, process unit information, and the inventory of all subject equipment with
details of individual components. These initial documents should be evaluated for
completeness, as discussed in the preceding chapter. If any aspect of the initial
documents are incomplete, the inspector should record this in the inspection notebook.
Each of the regulations also require the submission of semiannual or periodic
reports. The inspector should evaluate the most recent of these reports for
completeness and compliance with the requirements. Additionally, these reports should
be compared with each other and with the initial reports to determine the consistency of
information. Any inconsistencies or omissions of required information should be
recorded in the inspection notebook.
Following the review and evaluation of these reports, the inspector should
review previous inspection reports and related documentation such as field notes, post-
4-2
-------
inspection correspondence, and violation notices. These will identify previous
deficiencies and related issues, may record the estimated schedule of additions or
reconstructions the facility is planning to implement, and may record specific actions
the facility has committed to with respect to improving its compliance with the
equipment leak regulations.
The omissions, inconsistencies, unclear information, or question areas identified
by the above review should be noted in the inspection notebook. A complete and well
organized list of questions should be developed from these notations so that plant
personnel can be questioned or plant records checked during the inspection.
Inconsistencies by themselves.are not uncommon and do not necessarily indicate
violations. They may indicate poor implementation of recordkeeping and reporting
which can be corrected at the facility without the issuance of formal citations.
In the case of new regulations (e.g., the HON in 1995/96) or new plant
construction, the only source of information specific to the equipment leak programs
may be the initial report. In such cases, the inspector should examine agency files to
determine if other process areas at the facility have been previously regulated under
other equipment leak rules. If so, these reports may provide some background about
the facility's familiarity and performance with respect to equipment leak regulations.
Agency files should also be examined to obtain other compliance information,
correspondence, complaints, etc. regarding the facility. Other types of permits and
reports, such as those for other air regulations, wastewater, hazardous waste, or toxic
substance permits, should also be reviewed. A good example is TRI reports, submitted
pursuant to EPCRA requirements. Information contained in the initial equipment leak
reports should be compared with these other sources of information to assess the
consistency between the details reported.
Other inspectors who are currently or formerly assigned to the facility in
question should be interviewed for their experience and insight. For example, RCRA
and air inspectors should perform cross-media reviews of each other's inspection
reports.
Finally, up-to-date schematics or flow charts of regulated process areas at the
facility should be obtained to facilitate understanding of the physical site layout. A
major problem that confronts the inspector is determining if equipment exists in the
facility that is subject to the standard, but is not listed hi the in-plant records and
therefore is not being monitored and/or does not meet the equipment specifications.
This may be the most difficult part of an inspection. One method of addressing this
problem is to request a process unit material balance with a corresponding simplified
flow diagram. This information could then be reviewed hi detail to determine if there
appears to be equipment which should be listed and is not. If such areas exist, then the
on-site inspection or follow-up inspection should address this issue.
4-3
-------
4.1.1.2 Inspection Timing and Scope
An additional consideration during pre-inspection preparations should be the
nature of the inspection itself. Does the purpose of the inspection require an
unannounced visit or is some degree of notification acceptable? While it is desirable to
maintain some degree of flexibility as to the specific plant areas and records you will
examine while on-site, it is also necessary to allow key plant personnel an opportunity
to rearrange their activities to accommodate the inspection. The inspection involves the
review of many records and interviews with key company officials. Additionally, plant
personnel should be available to accompany the inspector during the facility walk-
through and to answer the inspector's questions.
If you plan to examine leak monitoring activities of plant personnel or their
outside contractors, obtain their current monitoring schedule. You need to ensure that
routine monitoring activities will be conducted during your visit, and you may want to
select an inspection date which coincides with monitoring of specific process areas.
Another aspect of inspection preparation involves making an assessment of what
can be accomplished within the time available to conduct the inspection. To make the
best use of limited time and resources, it is often useful to structure the inspection on
the basis of what can be accomplished within one full day.
For the inspection program discussed in this section, an initial interview with
plant officials and the site walk-through can be accomplished during the" morning, with
the afternoon devoted to review of records and a final interview addressing any
questions or observations resulting from the inspection. It may be necessary to review
some of the records prior to conducting the site walk-through, especially if the records
are needed to identify specific equipment to be inspected. In general, the site walk-
through should be completed before reviewing the records in detail to assure that
enough time is available for the walk-through. If the record review cannot be
completed on-site, copies can generally be taken back to the office.
It is useful to become familiar with the normal workday schedule at each plant
and to schedule your inspection accordingly. For example, the equipment leak
monitoring personnel may work an early shift (e.g., 6 am to 3 pm) so that maintenance
personnel can conduct same-day equipment repairs on a later shift. At a small facility
which employs a contract monitoring service, monitoring personnel may only be
available one or two days per week or during alternating weeks. It is generally difficult
to obtain useful observations or interviews if you schedule a process area walk-through
during the lunch break. More importantly, if you are flexible in the scheduling of
inspection activities, plant personnel may be more relaxed and responsive to your
inquiries.

4.1.1.3 Health and Safety Planning
A critical aspect of pre-inspeetion planning includes efforts to ensure that
personnel safety measures are in place. Contaminants of concern identified during the
preliminary review of the facility should be reviewed for exposure impacts, via dermal
or inhalation pathways, to ensure appropriate personnel safety gear is donned for the
inspection. Further, if potential risks exist, the inspector should wear a modified level
C and be able to don a respirator if monitoring equipment indicates levels in the
breathing zone exceed acceptable levels. Finally, when you schedule an inspection,
review with company officials what safety equipment is needed and what, if any, safety
equipment the company will provide.
4.1.2 Qn-SiteInspection
When you arrive at the facility, notice if there are any strong odors or visible
emissions. If there is a visible emission or strong odor, make sure it is thoroughly
documented before entering the facility. Try to find out the cause of the visible
emissions or odor after you have introduced yourself.
4.1.2.1Initial Interview
Once the inspector has identified himself or herself and has been granted entry
to the facility, the initial interview should be conducted. The objective of the interview
is to inform the facility officials of the purpose of the inspection, the authority tinder
wMch it will be conducted, the procedures to be followed, and your agenda for the day
of the inspection.
Discussion of the agenda should include an explanation of how you plan to
perform the inspection and should address any adjustments to your schedule
necessitated by plant operating schedules and conditions. With regard to leak
monitoring activities, it is probably best to observe calibration and monitoring
procedures as they are scheduled for that day, rather than to observe a possibly
rehearsed demonstration of these activities. Final specification of the records you wish
to inspect should be made at this time, along with agreement as to when they will be
available and where you can review them.
An important component of the inspection involves the evaluation of how well
company officials understand the applicable regulations and how effectively they are
acting to achieve compliance. The inspector should have key plant officials explain the
compliance program of the facility: including a general discussion of
problems/solutions, plant quality assurance procedures, and compliance program goals
of the plant. With regard to the inspection agenda for the day, the inspector should
4-5
-------
verify that the sources are subject to the standard and should ask for a description of the
process areas, principal products, and location of major emission points.
Before proceeding into the process areas, the inspector should review plant
safety procedures and confirm that all appropriate safety equipment is available.
Finally, plant officials should be advised of their right to request confidential treatment
of trade secret information. Company officials may review the inspection notes at the
end of the inspection and mark trade information confidential.
4.1.2.2 LeakMonitoringActivities
A key element of the facility inspection involves evaluation of the leak
monitoring program. This activity may include: interviewing monitoring personnel,
observing the calibration of leak detection equipment, and observing facility personnel
perform leak detection monitoring and spot checking of equipment sources for leaks.
Some facilities conduct monitoring with their own personnel, while others
employ an outside contractor to perform the leak monitoring. If in-house personnel
conduct the monitoring, an inspector may want to review the training and resources
provided to the employees. If an outside contractor is employed, the inspector should
determine if the facility employs any oversight or quality assurance procedures to
evaluate the performance of the contractor. Other pertinent items include: how
monitoring personnel report leaks, how repairs are scheduled, and how follow-up
monitoring is scheduled for repaired equipment.
The competency of the personnel who conduct the monitoring may be evaluated
both through observation and direct interviewing. The inspector should discuss the
plant procedures and schedules for monitoring, the recording of monitoring results,
general information regarding the analyzers in use, requirements of Method 21, and any
other areas the inspector determines to be of importance. These could include training
received, task supervision, and ancillary duties performed by the leak monitoring
personnel.
The leak detection equipment used to document facility compliance must be
calibrated on a routine basis. The inspector should observe calibration procedures
performed by the facility or contractor personnel who normally perform the routine
monitoring. The calibration precision tests, response time, and response factor tests
reveal whether the instruments are operating properly for the specific applications. The
inspector should witness the calibration procedures and should note any deviations from
the Method 21 procedures.
A number of other factors can be important such as: probe cleanliness, probe
leakages, gas flow rates, improper warmup period, incorrect zero, or meter adjustment.
4-6
-------
If the meter readout cannot be adjusted to the proper value, a malfunction of the
analyzer is indicated and corrective actions are necessary before using the analyzer.
The inspector should verify that the correct calibration gases are used and that the gases
are within the proper range. The inspector should record the instrument response time,
response factors, and calibration precision tests.
After the calibration procedure is complete, the inspector should observe the
plant personnel's or private contractor's technique hi performing actual leak detection
measurements. The plant personnel should be able to correctly monitor fugitive
emissions from all the equipment types at the plant site. Additionally, the plant
personnel should be able to correctly determine background concentrations. Any
deviations from Method 21 procedures should be noted. Techniques for correctly
monitoring certain equipment items are described in the foEowing paragraphs. See
Appendix E in Volume n for a more detailed discussion of monitoring techniques.
Fugitive leaks from valves occur primarily from the valve stem packing gland.
The normal procedure is to circumscribe the valve stem with the probe held at the stem-
packing interface. Maintaining such a close proximity to the stem is necessary in order
to obtain accurate measurement because of the relatively poor capture effectiveness of
the probe design. The presence of strong cross-draft wind further reduces the probe
capture capability. For these reasons the proper placement of the probe is critical. It
should be noted, however, that this monitoring requirement dictates that the inspector
position himself or herself in the immediate vicinity of the leak because most probes are
relatively short in length. Caution: If the inspector detects unsafe conditions, he or
she should stop observation and inform plant personnel. All involved parties
should follow their organization's safety procedures.
Certain monitoring procedures can be employed to minimize the risk of such
exposure. Whenever feasible, equipment to be monitored should be. approached from
downwind. Concentrations of equipment hi a sheltered area should be approached
relatively slowly from a more open area. In both cases, use your sense of smell and
visual observation of the instrument background reading as an early means of detecting
elevated concentrations.
Fugitive emissions from pumps occur from the pump shaft seal used to isolate
the process fluid from the atmosphere. Monitoring must be performed within one
centimeter of the seal and the rotating shaft. Caution: A rigid probe tip should not
be used near the rotating shaft because it could break if the monitoring personnel
were not able to hold the probe absolutely steady during the measurement. A
flexible tip is usually added to the end of the rigid probe when sampling pumps. If the
housing configuration prevents a complete traverse of the shaft periphery, sample all
accessible portions. Additional points on the pump or compressor housing where leaks
4-7
-------
could occur include flanges and other connections, and these should be sampled. Also,
look for liquid leaks from the stuffing boxes of pumps.
Care must be exercised when monitoring sources, such as valves and pumps,
that handle heavy liquid streams at high temperatures. Relatively nonvolatile organic
compounds can condense hi the probe and detector. Both the instrument response to
the emissions and the instrument return to zero may be slowed due to the condensation
of these compounds.
Fugitive leaks from flanges or other connectors typically occur at the flange or
connector sealing interface. For all connections, the probe should be positioned at the
outer edge of the flange-gasket interface, and monitoring should be conducted over the
entire circumference of the flange.
In most cases, the configuration of pressure relief devices prevents sampling at
the sealing interface. However, for those pressure relief devices equipped with an
enclosed discharge pipe, extension, or horn, the sample probe inlet should be placed at
the approximate center of the exhaust area relative to the atmosphere. Also, sample at
any "weep hole" at the bottom of such devices.
Certain fugitive leak sources are subject to a "no detectable emission"
regulation, i.e., the difference between the background organic vapor concentration and
the concentration measured at the source should not be greater than 500 ppmv. The
background concentration is determined by placing the probe one to two meters upwind
of the source. If other equipment interferes with the background measurement, the
upwind monitoring location can be as close as 25 centimeters.
Leak monitoring personnel should record the highest instrument reading
obtained at each piece of equipment. For fugitive VOC sources that have a highly
variable leak rate, the maximum sustained concentration or maximum repeated
concentration observed should be recorded.
During observation of the leak monitoring, the inspector should note how well
the monitoring personnel keep track of their monitoring equipment. While monitoring
is underway, the probe tip should be routinely checked and cleaned out as necessary.
Instrument background readings and return to zero rates should be monitored
periodically. Also, note whether monitoring personnel are equipped with and using
appropriate tags to mark leaking equipment.
Finally, note the number of equipment components and the number of leaks
detected by the monitoring personnel. These can be used to calculate rough estimates
of leak monitoring rates (i.e., valves per hour or total components per hour) and
component leak rates (e.g., eight leaking valves out of 150 tested equals six percent
4-8
-------
leak rate). These rates can be compared to leak monitoring rates and component leak
rates calculated from the records for the same or similar process areas. A large and
consistently repeated difference between reported rates and observed rates may indicate
that monitoring personnel are changing their procedures in some consistent fashion
while being observed by the inspector.
In addition to observing the performance of routine monitoring, the inspector
may wish to have the monitoring personnel spot-check a representative sample of
equipment for leaks. This should be done by observing personnel perform leak
detection monitoring on each type of equipment subject to the standard. The spot-
checks should include:
* recently leaking devices;
* "no detectable emission" devices;
* exempt devices (verify compliance).
Finally, if a facility is using closed vent systems and control devices, ensure
compliance with minimum temperature, residence time, efficiency and no detectable
emissions requirements. If flares are being used, inspect for no visible emissions as
determined by Reference Method 22.
4.1.2.3 Process Area Inspection
In addition to observing the leak monitoring program, an inspector should
devote some time to observation of the process area itself and interviewing process
personnel regarding their roles in the equipment leak program. By doing so, an
inspector can determine compliance with observable requirements such as equipment
tagging and gain a better understanding of the program implementation.
The degree to which process area personnel will be aware of and involved in the
equipment leak program will vary from facility to facility. At a rninimum, there should
be a designated individual (process area chief or shift foreman) responsible for (1)
documentation of visual inspections, (2) maintenance of on-site logs, and (3)
coordination between leak monitoring and equipment maintenance. Other areas in
which process personnel may be involved include (1) performance of first attempt at
repair, (2) oversight or quality review of leak monitoring personnel, and (3) on-site
responsibility for equipment markers and removable equipment (e.g., end caps or
plugs).
Perhaps one of the most important areas to discuss with process personnel is the
issue of coordination between leak monitoring and equipment maintenance personnel.
4.9
-------
Lack of communication between these groups is a significant source of errors and
compliance problems. How well the facility understands these problems and the types
of procedures undertaken to correct or prevent such oversights can reveal a lot about
the development and effectiveness of a facility's equipment leak program.
Observation of the process area should include verification of component
tagging, observation of end caps or plugs on open ended lines, inspection of sampling
connection systems and equipment in vacuum service, and evaluation of the operation
of various control devices.
Errors and oversights with respect to component tagging requirements are a
common problem which can be directly observed by the inspector. All equipment that
is scheduled for repair or to be monitored following repair must be clearly labeled. An
inspector can use records and reports to develop a list of components that should be
tagged and can then directly inspect those components to confirm the tags are being
applied and maintained. For equipment that will not be repaired until the next process
turnaround, the inspector can review the process equipment where the component is
located to confirm that such repairs cannot be accomplished without a process
shutdown.
Open-ended lines are frequently out of compliance (e.g., no plug or end cap)
and can be directly cited as a violation as a result of on-site inspections. Plant
personnel may lose or misplace end caps or plugs when such lines are opened, then
simply forget about them. An area-wide maintenance activity may result hi numerous
lines with missing caps.
Sampling connection systems should be examined to confirm that the vent
properly returns process fluids to the process. Similarly, equipment in vacuum service
should be examined to confirm that equipment to create such a vacuum is in place,
operating, and venting to a control device.
Each dual mechanical seal with barrier fluid system is required to be equipped
with a sensor that monitors the chosen criteria to detect a system failure. This sensor
must be checked daily or be equipped with an audible alarm. The inspector should
verify that the sensor has an alarm which is working properly or that the sensors are
being monitored daily.
If a control device is being used to control equipment leak emissions, the
inspector needs to observe several items. The first is the identification of the control
device and the manner in which the owner or operator is monitoring its operation.
Following are several questions that should be answered during the inspection:
» Why type of control device is used?
4-10
-------
• What is the claimed control device efficiency?
» Is the efficiency measured (tested) or calculated? Obtain a copy of any
of these test results or calculations.
» For incineration devices, what is the combustion temperature (from the
field or control room)?
» For each type of control device in use, what are the critical parameters
that demonstrate compliance (e.g., adsorber pressure drop/regeneration
cycle time, scrubbing fluid flow rate/pressure drop, final temperature
leaving condenser)?
* For flares, during normal operation what is the net heating value and exit
velocity of the flare gas? Is the velocity and net heating value of the
flare gas measured (tested) or calculated? Obtain copies of these test
results and/or calculations. Check the flame indicating device (probably
a thermocouple readout) in the field or control room for proper
operation. Observe the flare for visible emissions.
The inspector should evaluate the parameters chosen and the rationale for this
selection to determine if these parameters are appropriate to monitor proper operation
for the type of control device. This evaluation may need to be done off-site if the
inspector is not readily familiar with a particular type of control device.
4.1.2.4 Inspection of Records
Recordkeeping requirements and strategies for the review of records have been
addressed in Chapter 3. The primary objective of the record inspections is to minimize
fugitive emissions through requiring adherence to the recordkeeping requirements of
the regulation. Records that are required to be kept by the facility (and not reported)
should be reviewed by the inspector during the on-site inspection. The inspector should
determine what information needs to be obtained to document compliance. In
particular, the inspector should identify missing information, incomplete data or reports
and inconsistencies in the available background material, and specifically seek to extract
this information from on-site facility reports for the purpose of making a compliance
determination. Likewise, if noncompliance is suspected, the inspector should
concentrate efforts on obtaining necessary documentation for verifications.
The first step in the records review should be to determine if the records are
complete according to the regulations. After determining the completeness of the
records, a check for consistency and validity should follow. An inspector should take
along a few of the most recent semiannual reports so that comparisons can be drawn
4-11
-------
between the information contained in these reports and the information in the on-site
records, especially if during the pre-inspection review the inspector identifies any
inconsistencies. Alternatively, the inspector may copy the appropriate records and
perform this comparison off-site. If any equipment is complying by an option of the
regulations that requires annual testing, then it is advisable to bring semiannual reports
which contain test results to check for consistency with the complete test reports. The
records for leaking pumps, compressors, and valves should be compared with the
numbers in the last several semiannual reports. Any inconsistencies between the
reports and records should be noted.
The inspector should then review the monitoring data to ascertain if the control
device is being operated according to its design. The records must also contain design
specifications, instrumentation diagrams, etc. so that this comparison can be drawn.
The records are to contain a log of periods when the closed-vent systems and control
devices are not operated in accordance with the design specifications. The duration and
frequency of noncompliance episodes should be noted. The inspector should compare
his findings regarding such periods (based on a review of the monitoring data) with the
instances recorded in the log. Any inconsistencies should be noted in the inspection
notebook.
The test data pertaining to no detectable emissions equipment or valves
complying with percentage of valves leaking provision that was reported should be
compared with the test information contained in the records. Again, any
inconsistencies should be noted. A test for a process unit complying with the percent
leakage that indicates greater than two percent leakers is a violation. Any instance
where such a test was conducted and not reported should be noted and evaluated as a
possible inconsistency or a violation.
4.1.3 Post-Inspection Review and Reports
4.1.3.1 Post-Inspection Review
The post-inspection process should begin by reviewing the applicability
determination to ensure that all questions about the facility as a whole and all individual
process units have been fully answered. The equipment listings should also be
reviewed.
There are two fundamental questions that an inspector should consider during
this post-inspection data sorting.
• Is the recordkeeping system adequate to track monitoring, leaks, and
repairs?
4-12
-------
* Are the monitoring staff, equipment, and procedures adequate?
The answers to these questions and rationale for these answers should be contained in
the inspection report. If the response to either of these is no, suggestions should be
made to proper plant personnel to address correction of the existing problems.
4.1.3.2 Post-Inspection Reports
Upon completion of the walk-through inspection, the inspector should begin
preparing the inspection report while all the events of the inspection are still fresh in his
or her mind. The inspector should prepare the report before conducting another leak
detection inspection. When two or more inspections are done at one time, it becomes
difficult to mentally separate one from another. The facility data contained in the initial
report, the semiannual reports, as well as results of the facility record review and the
inspection, constitute the information available to the inspector to evaluate compliance
with the regulations. Additional information, elaboration or clarification may come
from the inspector's field notebook. If the inspector feels that it is needed, letters may
be issued or phone calls made requesting additional information. The instance may
occur where a return visit to the plant is necessary. These follow-up type inspections
should be abbreviated in nature and focus on the unanswered questions or problem
areas.
The next phase of the post-inspection process is to write the inspection report.
The report organizes and correlates all evidence gathered during the inspection into a
concise and useable format. The report serves to record the procedures used in
gathering data and gives factual observations and evaluations drawn in determining
facility compliance. The inspector's report will also serve as part of the evidence for
any enforcement proceeding or compliance-related follow-up activities.
The inspection results should be organized in a comprehensive, objective and
accurate report. The recommended report elements are listed below:
• Introduction
» Compliance Status for Regulated Equipment
» Evaluation of Observed Program
• Data
* Summary
4.1.4 Preparation for Subsequent Inspections
After completing the report, the inspector should prepare for the next inspection
while the facility's processes are still fresh in his or her mind* This can be
4-13
-------
accomplished by preparing a list of items to be checked and information to be reviewed
or gathered during the next inspection.
There are several suggestions to be considered for subsequent inspections at a
facility. The pre-inspection preparation should basically be the same for each
inspection. The inspector should review all the information contained in the facility's
file including the initial and semiannual reports. The semiannual reports that have been
submitted since the last inspection should be reviewed most carefully. The past
inspection reports should also be reviewed. If any items were noted in these reports
which required action by the facility, then the semiannual reports should be examined
with these specific areas in mind. There also are items to consider regarding the on-site
inspection. Due to the large number of records that are required, it may be impossible
to review all records on each visit. If this is the case, it is a good idea to spot-check a
different portion of the records during each inspection. It is also suggested that the
inspector check a different area of the plant by general walk-through and equipment
spot-checks in an effort to eventually cover the entire affected facility.
4.2 DIRECT MONITORING OF COMPONENTS
The use of monitoring equipment by an inspector introduces an added level of
complexity to the inspection process and may produce unsatisfactory results if the direct
monitoring is not carefully planned. On the other hand, some detailed inspection data
suggest that actual leak rates are often much higher than what is reported by the
facilities, and some local agencies are convinced that a comprehensive direct
monitoring strategy is necessary for effective enforcement of the equipment leak rules.
However, the use of direct monitoring by inspectors does not necessarily guarantee an
effective regulatory program in and of itself.
In recent years, the National Enforcement Inspection Center (NEIC) of U.S.
EPA has conducted a number of comprehensive sampling inspections of facilities
subject to 40 CFR 60, Subpart GGG, NSPS for petroleum refineries. These inspections
included some facilities at which direct monitoring had been included as part of the
local agency's inspection procedures. A typical NEIC inspection involved two or three
inspectors conducting direct monitoring of eight or ten process areas. Plant personnel
or their contractors accompanied the inspectors and conducted their own monitoring,
employing the same methodology used by the EPA inspectors (Method 21). In all
cases, the NEIC inspections measured leak rates at a majority of process areas that
were substantially higher than leak rates currently being reported by the facilities. A
typical inspection of ten process areas would find seven or more process areas with leak
rates of three to five times the reported rates. In all cases but one, leak rates found by
the plant personnel accompanying the inspection agreed with the findings of the
inspectors.
4-14
-------
These inspections suggest that the primary problem is the monitoring
methodology employed by the facilities or their contractors. Although ostensibly
following Method 21 procedures, the monitoring personnel appear to be performing
cursory examinations in an attempt to complete as many inspections as possible within
an allotted period of time, resulting in a chronic under-reporting of leak rates.
These inspections also illustrate some of the difficulties associated with
evaluating compliance with the equipment leak rules. If a facility is conducting the
required monitoring, performing repairs on schedule, and complying with all of the
recordkeeping and reporting requirements, it can be extremely difficult to demonstrate
that the facility is not achieving the emission reductions expected from the reported
level of performance. The inspector can only periodically observe performance of the
monitoring personnel and can at best only develop circumstantial evidence of
inconsistencies between routine and observed monitoring practices.
The use of direct monitoring within the context of an agency inspection program
needs to address this issue of verifying that the monitoring and testing procedures
utilized by the plant are in full compliance with the Method 21 sampling methodology.
To accomplish this, an inspector could monitor a representative sample of equipment
within a process area and compare the results with the history of leak checks for that
process area conducted by the plant. A large discrepancy between the inspector's
findings and the plant's records would indicate that the monitoring procedures of the
plant need to be improved.
Another means of evaluating the monitoring procedures of plant personnel is to
have them monitor all of the components hi a specific area of a process unit, while the
inspector follows and monitors the identical equipment. Alternatively, the inspector
could accompany the plant personnel and monitor each piece of equipment
concurrently, so that both operators obtain the same reading. In the first case,
discrepancies in the results of the two evaluations would indicate a need for improved
monitoring technique, while the second scenario allows the plant personnel to directly
perform the monitoring method as practiced and approved by the Agency.
4.2.1 ]Process Area Inspection
Evaluating the monitoring technique of plant personnel is useful on an
occasional basis, but conducting inspections of a representative sample of equipment
within a process area is probably preferable as a long-term inspection practice. It
directly addresses the performance of regulated equipment at a facility and can be more
consistently replicated as an inspection procedure. Plant personnel would also have the
opportunity to accompany the inspector with their own monitoring equipment without
interfering with the inspection procedure.
4-15
-------
Determining what constitutes a representative sample of equipment within a
process area is an issue of both numbers and accessibility. Equipment that is not
classified as difficult or unsafe to monitor, but which requires some exertion to reach
(e.g., climbing towers) should be systematically included in the inspector's sampling
pattern. Equipment such as pumps and compressors, which are normally present in
small numbers within a process area, can all be sampled. Valves, normally present in
very large numbers within a process area, need to be systematically sampled. Other
equipment, including connectors, pressure relief devices, and equipment subject to no
detectable emission limits, can be spot-checked during the inspection.
As a general rule of thumb, 200 to 300 valves can be inspected within a half day
of direct monitoring and are usually a sufficient number to constitute a representative
sample. Very large process areas (i.e., more than 1,000 valves) may require a larger
sample. A purely random sampling of valves is often infeasible and is usually not
necessary so long as other steps are taken to maintain representativeness. For example,
if a process area has four reactor columns which require climbing to access equipment,
select one or two columns and monitor all valves on those selected.
Usually, one or two cohesive subsets of a large process area can be identified
and sampled as a representative sample of that area. Often, the facility will have an
established "start-to-finish" route to be used by its own monitoring personnel or
subcontractors. Using a process flow diagram, it may be possible to divide the route
into three or four sections and then select any one section as the representative sample
for that area. Any equipment type such as pumps, reactor columns, surge control
vessels, etc. that are concentrated in a specific area should be added to the inspection.
Depending on the number involved, all or a portion of these units (as well as valves and
other connectors associated with the units) can be sampled.
To be most effective, direct monitoring needs to be repeated. An ideal practice
might be to test each process area at a regulated facility once per year. The specific
process area to be tested on any given day would be unannounced. If annual testing of
all process areas cannot be achieved, the selection of process areas to be tested should
be guided by the inspector's on-site observations and evaluation of the facility's records
and reports. Additionally, certain process areas can be expected to leak more often
than others and should therefore be inspected more frequently. These areas include
those processes containing more volatile materials and processes operating at elevated
temperatures or pressures.
4.2.2 Inspection Preparation
Preparing for and conducting an inspection that includes direct monitoring of a
process area is very similar to the procedures for a walk-through inspection described
earlier in this section. The principal difference is that performance of the monitoring
4-16
-------
by the inspector replaces the observation of monitoring by facility personnel. Other
inspection activities, including preview of reports, on-site observations of regulated
equipment, interviews with plant personnel, and on-site inspection of records remain
virtually unchanged. Direct monitoring activities may increase an inspector's risk of
exposure and the adequacy of safety planning steps should be reviewed.
Several steps need to be added to the preparation stage to ensure a successful
inspection. These include equipment maintenance, supplementary supplies, and
planning the monitoring approach.
Prior to each inspection, the monitoring instruments and supporting equipment
should be inspected to confirm that everything is in good working order and will be
available on the dates needed.
The next step in the pre-check procedure is to confirm that the sampling
instrument is properly calibrated. This includes checking that the monthly calibration
precision test has been conducted and scheduling a daily calibration test for the
inspection date. If a calibration test is to be performed in the field, confirm that
disposable cylinders of certified gas mixtures in the appropriate concentrations will be
available.
Finally, check the condition of the analyzer backpack. All analyzers should be
outfitted so that the instrument can be carried on the inspector's back. Additionally, the
pack straps should be equipped with clips for the hand-held probe and the inspector's
clipboard. This allows both hands to be free for climbing ladders. Use of a backpack
will greatly reduce fatigue, and the probe can also be clipped to a strap when the
inspector is writing in the clipboard.
Selection of the specific process area or areas to be tested should be
accomplished during the inspection preparation. This may be done as a result of a
preliminary review of reports and records, notes from previous inspections, or an
annual schedule. Process area schematics, leak monitoring and repair records, and
information about process materials (type of service, heated or pressurized processes,
volatility of process materials) can be used to make such determinations. These
materials should be requested in advance from the facility. When the inspection is
scheduled with the facility, the inspector should request that the most recent records for
four or five process areas (including the one to be directly monitored) be available at
the beginning of the inspection. This will allow the inspector to review the most up-to-
date information on the process area immediately before the inspection.
4-17
-------
4.2.3 Pn-Site Inspection Procedures
During the pre-inspection meeting, identify the specific process area(s) you plan
to inspect and monitor and review the most recent records from those processes. Also,
request to see a copy of the permit and check to see if the permit is current and valid.
Compare your agency's current equipment list with the source's equipment list. Check
existing permit conditions and ask if any changes have been made to the operation
which are not reflected in the permit.
Immediately prior to entering the process area, warm up your analyzer
instrument, check that all components are operating properly, and perform a span check
with the appropriate calibration gas. Upon entering the process area, ask the
production personnel if there are any leaking components and when they were found
leaking and tagged. Compare any reported leakers with the most recent records for that
area. While conducting the monitoring inspection, observe tags on leaking components
to ensure that they are properly dated and that the allowed time period for repair has
not expired.
While conducting the monitoring inspection, use your senses of sight, smell, and
hearing to survey an area for leaks and to help you zero in on leaking components. As
you enter an area and proceed from component to component, note any suspect odors
and watch for any increases in background concentrations on your analyzer gauge.
Look for any distortion emanating from the equipment similar to the distortion seen
from infrared radiation near the ground or on a roof on a hot day. Also, look for such
distortions in the shadow of the equipment. If background noises are not excessive,
you may also detect leaks by hearing them. Investigate the source of any unexplained
hissing sounds. Caution; Your risk of an exposure that exceeds acceptable levels
can increase significantly as you zero in on leaking components. Be certain that all
appropriate safety gear is donned before proceeding with your investigation.
Always look for liquid leaks from components in the form of drips or spray
mist. Investigate any stains which may be the result of recent evaporation of such
leakage. If process or sealing fluids are present at valve stems, pump shafts, or
connection points, look for bubbles which may indicate a leak.
When using the analyzer to check each piece of equipment for a leak, move the
probe slowly along the interface where a leak may be likely, holding the probe tip as
close to the interface as possible. Look for blips in the meter reading, which may
indicate that you recently passed over a leak. Remember that there is a response time
lag (usually less than five or ten seconds) between the time a VOC is sucked into the
probe and the time that a meter indication is observed. When a blip is observed, slowly
retrace your sampling route until you find the point at the interface where the leak is
highest.
4-18
-------
The leak rate is measured by finding the highest concentration of the leak. At
the interface where the leak is highest, vary the angle of the probe to maximize the
concentration. If possible, block any wind or draft from the area you are checking.
Read and record the maximum concentration that you can maintain for several seconds,
not just the peak of a spike. If the leak is intermittent or pulsing, note the maximum
concentrations across several cycles and record the maximum of these readings. In the
case of gross leaks (e.g., 50,000 ppp or more), attempting to read the maximum
concentration following this procedure may lead to flame-out or saturation of the
analyzer. Addition of dilution air to the probe intake may be necessary to obtain an
accurate reading. Alternatively, the inspector may record the highest reading
obtainable without risking damage to the analyzer and note any supplementary
information (odors, etc.) associated with the leak.
Within the portion of a process area selected for direct monitoring, certain
components are more likely to leak than others, and these components should be
carefully examined. Flow control valves, which are operated more frequently than
other valves, are correspondingly more likely to leak. There are often valves and
connectors located near pumps and compressors that are subjected to vibrations and
pressure surges. A pump that is not running is more likely to leak at the shaft seal than
one which is operating. Gauges and meters that have been repositioned by plant
personnel are more likely to leak as a result of such movement. Finally, any equipment
that has been worked on or recently installed is more likely to leak. Visual cues (tool
marks, new looking or cleaner components) as well as the facility's monitoring and
repair records will help you identify such components.
It may not be necessary to record every component you examine, especially if
you can use a process diagram to document the areas inspected. Ask the plant
personnel who accompany you during the inspection to keep a running tally of the
number and type of each component inspected. When a leak is detected, record the
leak rate and the ID for the leaking component. Plant personnel should tag each
leaking component. If plant personnel make an initial attempt to repair the component,
try to reinspect these components to confirm the results of the initial repair attempt. It
may be possible to do this after monitoring of the selected area is completed or at the
end of the day. If personnel initiate repair attempts while you are conducting the
monitoring inspection, do not slow down your own inspection schedule by waiting to
monitor repairs. Come back after completing your monitoring schedule.
Detailed inspection procedures for valves, pumps, compressors, pressure relief
devices, connectors, and other equipment have been discussed earlier in this chapter.
While conducting the inspections, remember to look for grease or other materials mat
could plug the probe and continually check the probe tip for any obstructions. Also,
use caution when inspecting any moving equipment. Do not touch the surface of any
4-19
-------
rotating or reciprocating shaft with the probe tip of your analyzer. Use a short piece of
plastic or tygon tubing at the probe tip as an extra means of protection.
4.2.4 Post-Inspection Interview
Include a discussion of the findings from your monitoring inspection in the post-
inspection interview with plant personnel. Address any areas where the monitoring
results may result in a notice of violation, such as leaks from equipment designated for
no detectable emissions. If the monitoring results indicate a significant discrepancy
with leak rates reported by the facility, discuss this issue and elicit comments from the
plant personnel regarding specific actions to be taken to address the problem.

RECOMMENDED INSPECTION TECHNIQUES AND PROCEDURES
5.1 INSPECTION PROGRAM DEVELOPMENT
Chapter four briefly referred to the fact that the emphasis of equipment leak
inspections will vary in response to a variety of factors. One important factor is the
state of LDAR program development at a new facility or at a facility newly subject to a
new rale. Initial inspections at such facilities would focus on applicability, appropriate
classification of equipment, and documentation of exemptions. Later inspections would
focus more heavily on inspection of monitoring practices, reeordkeeping, and repair
procedures, and addressing the correction of identified deficiencies. Assuming the
LDAR program at the regulated facility matures and stabilizes, on-going inspections
may evolve into a more-or-less routine pattern of compliance oversight.
However, even within the context of inspections at a facility with an established
LDAR program, the emphasis of individual inspections will vary. There may be one or
two annual inspections that address the facility as a whole in addition to periodic
inspections that look more closely at individual process areas. Intermittent events, such
as start-up following a process shutdown or the employment of new monitoring
personnel at the facility, may become the primary emphasis of individual inspections.
Finally, the experience level of the inspector may be a factor in the selection of
inspection emphasis.
Implementation of the HON equipment leak provisions provides a convenient
means of illustrating such an evolution of inspection emphasis. As the rule was
implemented, many chemical facilities found themselves subject to equipment leak
regulations for the first time. For those facilities already subject to NSPS or NESHAP
regulations, the HON was likely to introduce an expansion of the number of regulated
process areas as well as more extensive recordkeeping requirements and more stringent
leak standards. Such facilities may have found that current monitoring and
recordkeeping practices were inadequate, or even inappropriate, for the demands of the
regulations and the needs of the facility. Those changes may have resulted in an
expanded level of inspection activity for the regulatory agency as well as a need to
adjust the inspection emphasis in step with development of the LDAR programs at the
regulated facilities.
5-1
-------
At the outset of implementation of new LDAR requirements for a facility, the
first few inspections would focus primarily on applicability issues while developing
familiarity with the plant's initial approaches to monitoring, recordkeeping, and
equipment repair. Finding and reconciling any misclassification or oversight with
respect to regulatory applicability during the initial phase could avoid more serious
complications at a later stage. An inspector addressing this issue could consult with
personnel in the agency who have developed the facility's permits, study process flows
and material balances of the facility, and review the documentation and justification for
'those processes which have been classified as qualifying for various exemptions. At
this time, the inspector should also look at equipment classified as "difficult to monitor"
or "unsafe to monitor" to confirm that such equipment meets the applicable
requirements.
Once the issue of applicability has been adequately resolved, the inspector can
begin to concentrate on direct observation of the facility's monitoring program and
conduct visual inspections of individual process areas. While observing monitoring
activities, the inspector may devote one or two site visits to conducting side-by-side
monitoring with the facility's personnel. This would afford an opportunity to identify
and address any problems with monitoring techniques at the facility. In the case of
process area site visits, the inspector can interview operating personnel so as to gam
insight into how well they understand their role in developing compliance with the
equipment leak regulations. The inspector should also address issues such as proper
tagging of leaking equipment, performance of repairs within the allotted time, follow-
up monitoring of repaired equipment, visual inspections, and recordkeeping practices to
document these activities. The inspector should also become familiar with closed-vent
control devices at the facility and the equipment served by such devices.
After several rounds of monitoring have been completed and the first one or two
periodic reports submitted, the inspector can relate his or her developed familiarity with
the facility to the information in these records and reports. The inspector will be able
to identify those process areas and equipment types that are exhibiting higher than
average leak rates and may even be able to identify specific pieces of equipment as
"chronic leakers."
The next phase of inspection activities, beginning perhaps midway through the
second year of regulations, would begin to incorporate direct monitoring of
representative portions of selected process areas. Once again, developed familiarity
with the facility will aid the inspector in selection of appropriate areas to be monitored.
Direct monitoring inspections can become an important part of inspection procedures
over the next several years, along with periodic observational inspections or walk-
throughs of larger portions of the facility.
5-2
-------
Maintaining consistent documentation in the form of inspection reports and
associated notes will help to develop a consistent background file on the facility. This
can be especially important as experienced inspectors are replaced by new personnel.
Ideally, one or two inspectors should be continuously assigned to the same facility or
group of facilities and should be responsible for the full range of air related permits and
emission control programs at those facilities. This will help to reinforce a fuller
understanding of the facilities and will also broaden the range of regulatory expertise
among the individual inspectors. Additionally, if possible, a new inspector should
accompany a more experienced individual on several inspections for training. Finally,
whenever feasible, experienced inspectors should accompany each other on inspections
of their respective facilities. This will help to expand the inspector's perspective by
exposing them to equipment leak programs at other facilities and will also help to
reinforce consistent monitoring and inspection techniques among the inspection staff.
A final, optional phase of inspection activities would be to conduct
comprehensive monitoring inspections of individual facilities. This would involve two
or three inspectors visiting a facility for several days to conduct complete monitoring of
selected process areas and/or representative portions of larger process areas. Such
inspections could be patterned after the in-depth inspections of the NEIC. Facility
personnel would accompany the inspectors and conduct side-by-side monitoring of
selected process areas. These comprehensive monitoring inspections could accomplish
three purposes: (1) evaluate and compare the extent to which the facilities are
accomplishing the emission reduction objectives of the regulations, (2) evaluate the
effectiveness of the agency's inspection program, and (3) provide a basis for
documenting noncompliance in the form of under-reporting of leak rates at individual
facilities. As a long-term program, comprehensive monitoring inspections could be
performed on all facilities or a subset of facilities within an agency's jurisdiction on a
cycle of once every four or five years. Additionally, comprehensive inspections could
be performed at individual facilities whenever such action is necessary.
5.2 WORKING WITH REGULATED FACILITIES
Over the long term, a successful inspection and regulatory enforcement program
for the equipment leak regulations is more likely to succeed if the inspector can develop
a cooperative working relationship with the regulated facilities. Such a relationship will
make it easier for the inspector to obtain information about the facility in the form of
reformatted or supplemental reports and other information not specifically identified by
the recordkeeping requirements. The inspector may also find it easier to elicit verbal
information about planned changes or developments within the facility which can be
useful to the planning effort for future inspections. In exchange, the inspector may be
able to assist the regulated facility by providing information or assistance helpful to the
facility's development of a successful equipment leak program. Such a relationship can
5-3
-------
therefore improve the probability that enforcement of the equipment leak regulations
will contribute to effective and long-term reductions of this class of emissions.
The issue of component monitoring technique is a particularly important area in
which the inspector can potentially contribute assistance. Facility personnel or
contractors responsible for monitoring may feel inclined to complete the monitoring of
as many components as possible within a limited amount of time. This emphasis on
speed and efficiency may result in a decline in monitoring technique, with personnel
moving their analyzers too quickly over the equipment or not holding the probe tip
close enough to those points where leaks are likely to occur. As previously discussed,
the inspector can review and critique the monitoring technique of plant personnel or
engage in side-by-side monitoring with the personnel. This creates an opportunity for
the inspector to demonstrate correct monitoring techniques and can improve the
probability that reported leak rates accurately reflect conditions at the facility.
Collaboration in the area of monitoring technique can be taken one step further
by making agency training available to monitoring personnel from the regulated
facilities. Shared training further reinforces the objective of getting the facilities to
practice appropriate monitoring techniques and may also contribute to cost savings for
both the agency and the facilities with respect to training costs. For example, the South
Coast Air Quality Management District (SCAQMD) has found shared training to be a
successful approach. The SCAQMD is planning to expand their program to include
certification of facility monitoring personnel.
As an inspector develops experience with equipment leak programs and learns
more about how other facilities are developing their programs, the inspector may be
able to offer additional assistance or advice in a number of areas. An inspector can
develop such experience from accompanying other inspectors to other facilities, and
through long-term observation of different approaches within facilities assigned to the
inspector. If one or two facilities within an agency's jurisdiction are achieving
exceptional success with their leak minimization programs, an inspector can inform
other facilities of such accomplishments and encourage information sharing between the
facilities. An inspector may also be aware of additional potential resources, such as
trade associations, that may be a source of help to a facility.
Some of the approaches used by successful facilities include in-plant oversight
of monitoring procedures, use of internal leak standards, innovative component tracking
systems, use of advanced repair systems and materials, and installation of new
equipment with improved leak minimization performance.
In-plant oversight of monitoring involves the application of quality assurance
techniques to the equipment monitoring and leak reporting activities. Some facilities
that employ subcontractors have found it advantageous to obtain analyzer instruments
5-4
-------
and train one or two plant personnel to provide oversight and backup to the contract
monitoring service. By developing an in-house monitoring capability, the facility is
better able to identify and correct any deficiencies in the contractor's performance. As
a backup resource, the in-house personnel are most valuable as a means of assuring
appropriate follow-up monitoring and reporting of repaired equipment.
Although most contract monitoring services provide a database and
recordkeephig system as part of then: package, some facilities prefer to develop an
internal system. This allows for faster acquisition of reports, enables report formats to
be modified, addresses some issues of confidentiality, and creates the opportunity to
incorporate the monitoring and recordkeeping systems in the development of additional
program elements.
Facilities that perform their own monitoring cite a number of factors which
reinforce their commitment to this approach. Having plant-wide in-house monitoring
capabilities permits the establishment and maintenance of higher performance standards
and allows for greater flexibility in the utilization of monitoring resources. This
flexibility can be applied to leak testing equipment during process repair and
maintenance activities, during startup after a process shutdown, and for spot-checking
suspect equipment without waiting for the routine monitoring schedule.
Internal plant standards refer to a potentially broad range of activities designed
to ensure compliance by doing more than the minimum requirements of the regulations.
Some plants will repair equipment before applicable leak rate definitions are exceeded
(e.g., conduct an initial repair procedure on any equipment leaking at 5,000 ppm or
more when the leak definition is 10,000 ppm) Other strategies include supplemental
monitoring as described previously, replacement of equipment which continues to leak
after two or more attempts at repair, and repair of equipment which could be classified
as non-repairable. In a related approach, many facilities have incorporated
environmental compliance, waste minimization, pollution prevention, and similar goals
within the context of total quality management programs or other production quality
initiatives.
Component tracking addresses the utilization of repetitive monitoring data to
evaluate the long-term performance of equipment. This can include the identification of
equipment which leaks chronically or performance comparisons of alternative
components within a process area. The increased sophistication and flexibility of
internalized databases and recordkeeping systems lends support to the utilization of
component tracking strategies.
Equipment leak regulations have been in effect at some facilities for a number of
years. Efforts to minimize equipment leaks have contributed to advances in repair
techniques and materials and to development of new equipment with improved leak
5-5
-------
minimization performance. Improved repair techniques have greatly expanded the
number and types of equipment which can be repaired in place, without a process
shutdown. Improved component materials such as specialty gaskets can improve the
performance and extend the life of existing equipment. Finally, the design of new
processes or reconstruction of existing process areas can incorporate leak minimization
efforts by reducing the number of valves, flanges, and other connectors within the
process system.
The leak standards and other specified control strategies within the HON are a
reflection of the achievable standards resulting from the improved equipment, repair
techniques, and information management strategies summarized above. Additionally,
the QIP provisions of the HON are based on leak minimization programs that have
worked for other facilities in the past. Although not formally required until Phase ffl,
an inspector might suggest that facilities implement QIP plans or an in-house equivalent
early on as a means of improving their opportunities to meet compliance with the
standard.

ABSTRACT
The purpose of this manual is to enhance an inspector's ability to conduct more
complete and effective inspections at facilities in the chemical industry that are subject
to federal equipment leak regulations. Equipment leak standards are designed to reduce
or eliminate emissions of volatile organic compounds (VOCs), volatile hazardous air
pollutants (VHAPs), and organic HAPs from the miles of piping and numerous
components found in chemical manufacturing processes.
This document is divided into three volumes. The first volume is a manual for
inspectors; the second and third volumes describe regulations that apply to the chemical
manufacturing and the petroleum refining industries, respectively.
Volume I has five chapters dedicated to helping an inspector:
• Chapter 1 states the goals, background, approaches to rale enforcement, and
organization of the document.
• Chapter 2 addresses applicability determinations: ensuring the correct rules are
being complied with at a facility, determining whether all appropriate
components have been identified, and ensuring the components are properly
classified by service.
• Chapter 3 discusses reporting and recordkeeping requirements for NSPS,
NESHAP, HON, and RCRA (recordkeeping only), and strategies for reviewing
reports and records.
• Chapter 4 covers on-site inspections: walk-throughs and inspections with the
inspector monitoring for leaks. It addresses pre-inspection activities, timing and
scope, interviews, leak monitoring evaluations, inspections of the process area
and records, and post-inspection reviews and reports.
» Chapter 5 discusses recommended inspection techniques and procedures.
Volume II tackles the equipment leak regulations applicable to the chemical
manufacturing industry.
« The first three appendices of Volume n summarize the regulations of 40 CFR
Part 60 Subpart W, Part 61 Subparts J and V, Part 63 Subparts H and I, Part
264 Subpart BB, and Part 265 Subpart BB; detail the differences among the
regulations; and give the requirements grouped by component.
• Appendix D describes the regulated equipment.
• Appendix E contains the "Method 21" approach to leak detection.
» Appendix F lists chemical manufacturing processes that are subject to HON.
• Appendix G lists organic HAPs that are subject to HON.
• Appendix H lists manufacturing processes and associated organic HAP
emissions that are subject to HON.
-------
Volume HI contains the equipment leak regulations applicable to the petroleum refining
industry.
* The three appendices of Volume DI summarize the regulations of 40 CFR Part
60 Subparts DDD, GGG, KKK, and QQQ, and Part 63 Subpart CC; detail the
differences among the regulations; and give the requirements grouped by
component.

Not applicable.
The batch processes provision is an alternative to complying with §§63.163 through
63.171 and §§63.173 through 63.176. Under the monitoring option for batch
processes, the standards are similar to those for continuous processes with the
monitoring frequency prorated to time in use of organic HAP.
Each time equipment is reconfigured for the production of a new product, the
reconfigured equipment is to be monitored for leaks within 30 days of start-up. This
initial monitoring of the reconfigured equipment oan not be used in determining
percent leaking equipment in the process unit.
Connectors are to be monitored in accordance with §63.174.
Equipment other than connectors are to be monitored based on the frequencies shown
below, which can be adjusted to accommodate process operations:

If a leak is detected, It must be repaired as soon as practicable, but no later than 15
calendars after detection. Delay of repair is allowed if equipment supplies have been
depleted and supplies had been sufficiently stocked before their depletion and the
repair is made no later than 10 calendar days after delivery of the replacement
equipment.

Pressure Test
Option
Not applicable.
Not applicable.
Not applicable.
Monitor for teaks when the equipment is in organic HAP service, in use with an
acceptable surrogate volatile organic compound which is not an organic HAP, or is in
use with any other detectable gas or vapor.
Each time equipment is reconfigured for production of a different product or
intermediate, the batch process train is to be pressure-tested for leaks before organic
HAP is first fed into the equipment.
Pressure test new or disturbed equipment when a batch process train is reconfigured.
Pressure testing not required for routine seal breaks, such as changing hoses and
filters.
Batch process equipment test using either:
» procedures specified for pressure or vacuum loss [see §63,180(0] or
* procedures specified for using a liquid [see §63,180(g)]
Each batch process that operates in organic HAP service during a calendar year must
be pressure tested at least once during that same calendar year.
For pressure or vacuum tests, a leak is detected if the rate of pressure change in
excess of 6.9 kilopascals (1 psig) in 1 hour; or if there is visible, audible, or olfactory
evidence of fluid loss.
For pressure tests using a liquid, a leak is detected if there are indications of dripping
liquid or other evidence of fluid loss from process units.
When leaks are detected, repairs must be made and a retest conducted before startup
of the process.
If the process unit fails this retest or the second of 2 consecutive pressure tests, the
equipment must be repaired as soon as practicable but not later than 30 calendar days
aftef the second pressure test.
Not applicable.

Not "in service"
determination
For demonstration;
Use procedures that conform to ASTM E-
260, E-168, B-169 to determine percent
VOC in process fluid that is contained or
contacts a piece of equipment.
Engineering judgement may be used to
estimate the VOC content if piece of
equipment had not been shown previously
to be in VOC service,
Administrator will require use of ASTM
Method D-2267b in even! of disagreement
to determine VOC content,
Compounds determined by EPA to have
negligible photochemical reactivity can be
excluded in determining VOC content of a
process fluid.
For demonstration:
Use procedures that conform to ASTM
Method D-2267,
Engineering judgment may be used to
determine percent VHAP clearly does not
exceed 10 percent.
Administrator will require use of ASTM
Method D-2267b in event of disagreement
to determine VOC content.
For demonstration:
Use Method 18 of 40 CFR Part 60,
appendix A to determine percent organic
HAP.
Engineering judgment may be used to
determine percent organic HAP does not
exceed 5 percent,
Owner/operator may instead determine
organic HAP content does not exceed 5
percent by weight.
For demonstration:
Use ASTM Methods D 2267-88, E 169-87,
E 168-88, E260-85, or Method 9060 or
8240ofSW-846.
Engineering judgment may be used to
estimate organic concentration.
Regional Administrator will require the use
of ASTM Methods D 2267-88, E 169-87, E
168-88, E260-85, or Method 9060 or 8240
of SW-846 in the event of disagreement to
determine VOC content.
Revisions of "In
service"
determination
None specified.
Determination of in VHAP service can be
revised only by following specified
procedures.
Determination of in organic HAP service
can be revised by either following specified
procedures or documenting a change in
process or raw materials no longer causes
equipment to be in organic HAP service.
If owner or operator determines that a piece
of equipment contains or contacts a
hazardous waste with an organic
concentration of at least 10% be weight, the
determination can only be revised by
following the demonstration procedures.

Initial survey:
« Monitor all connectors within first 12 months after initial start-up (new sources)
* Monitor all connectors no later than 12 months after compliance date (existing)
Subsequent monitoring frequency based on percent leaking:
» Annual: if aO.5% during last annual or biennial period
» Once every 2 years: if <0.5% during last monitoring period (monitor at least 40% of connectors
in first year and remainder in second year)
* Once every 4 years: if <0.5% during 2 year monitoring period (monitor at least 20% per year
until all are monitored within 4 years)
» Once every 2 years: 0.5 to <1% during 4 year monitoring period (monitor at least 40% of
connectors first year and remainder in second year)
• Annual: if > 1 % during 4 year monitoring period
For any connector that has been opened or otherwise has had its seal broken, monitor when
reconnected or within first 3 months of being returned to HAP service.
If leak is detected and it cannot be repaired, then the connector should be counted as nonrepairable
for purposes of determining monitoring frequency. If the owner or operator chooses not to monitor
connectors that have been opened or otherwise had the seal broken, then he cannot count
nonrepairable connectors for the purposes of determining monitoring frequency. The owner or
operator will instead set the nonrepairable component of the monitoring frequency equation to zero
for all monitoring periods.
A switch in alternatives requires initial monitoring no later than 12 months after reporting the switch.

Credit may be given for eliminating connectors if the following requirements are met:
• connector was welded after the date of proposal of the specific subpart that references this
subpart
* integrity of the weld is demonstrated by monitoring it according to the procedures in 63.180(b)
or by testing using X-ray, acoustic monitoring, hydrotesting, or other applicable method
* welds created after the date of proposal but before the date of promulgation of a specific subpart
that references this subpart are monitored or tested by 3 months after the compliance date
specified in the applicable subpart, and
* welds created after promulgation of the subpart that references this subpart are monitored or
tested within 3 months after being welded
If an inadequate weld is found or the connector is not welded completely around the circumference,
the connector is not considered a welded connector and is therefore not exempt.
In percent leaking connectors equations, optional credit for removed connectors is calculated:
0.67 * net (total removed - total added) number of connectors in organic HAP service that are
removed from the process unit after compliance date for existing units and after initial start-up for
new units. If credits are not taken, the credit = 0

REGULATED EQUIPMENT1
'Source: Handbook: Control Techniques for Fugitive VOC Emissions from Chemical Process

Chapters
Regulated Equipment
Equipment leak standards are designed to control
emissions of VOCs and VHAPs from regulated
equipment through the application of work practices
and equipment practices. The work practice most
commonly applied to control equipment leaks is the
LDAR program, which is discussed in detail in
Section 2.2.4.2. Subsequent chapters address the
monitoring, recordkeeping, and reporting
requirements of implementing a LDAR program
under NSPS or NESHAP standards. In this chapter,
regulated equipment is reviewed to illustrate how
monitoring programs are applied to specific pieces
of equipment.
Equipment practices include the use of specific
types of components, equipment design standards
or specifications, and operational standards for
certain types of equipment Equipment practices are
evaluated using performance standards that provide
a basis for monitoring or substantiating the
effectiveness of such control practices. Equipment
practices, briefly summarized in Section 2.2.4.3, are
addressed in greater detail in this chapter.
A general set of equipment is covered by all of the
equipment leak standards. Some equipment is
covered only by specific standards. For example,
product accumulator vessels are covered only by
the equipment leak standards for benzene. Also, the
vinyl chloride fugitive emission standards cover
additional sources (loading and unloading lines,
agitators, slip gauges, opening of equipment, and in-
process wastewater). Except for agitators, however,
the emissions from these sources generally are not
considered "equipment leaks." The equipment leak
standards also identify requirements for closed-vent
systems and control devices that may be used to
comply with the regulations.
3.1 Pumps
Pumps are used extensively in the SOCMI and
petroleum refinery industries, as well as in natural
gas processing plants, for moving organic fluids.
The most widely used pump is the centrifugal pump.
Other types of pumps that also may be used are the
positive-displacement, reciprocating and rotary
action, and special canned-motor and diaphragm
pumps (U.S. EPA, 1990).
Chemicals transferred by pumps can leak at the
point of contact between the moving shaft and
stationary casing. To isolate the pump's interior from
the atmosphere, all pumps, except the seal-less
type (canned-motor and diaphragm), require a seal
at the point where the shaft penetrates the housing.
The most commonly used seals in these pumps are
packed and mechanical (U.S. EPA, 1980a).
Pump stuffing box
gland
Figure 3-1. Diagram of simple packed seal (U.S. EPA, 1980b).
3.1.1 Packed Seals
Packed seals can be used on both reciprocating and
rotary action pumps. A packed seal consists of a
cavity ("stuffing box") in the pump casing filled with
special packing material that is compressed with a
packing gland to form a seal around the shaft. A
simple packed seal is illustrated in Figure 3-1. To
prevent buildup of frictional heat, lubrication is
required. A sufficient amount of liquid (either the
liquid" being pumped or another liquid that is
injected) must be allowed to flow between the
packing and the shaft to provide the necessary
lubrication. If this packing and/or the shaft seal face
degrade after a period of usage, organic compounds
can leak to the atmosphere.
REGULATED EQUIPMENT
page D-1
-------
3.1.2 Single Mechanical Seals
Mechanical seals, limited in application to pumps
with rotating shafts, can be single or dual. Basic
designs of mechanical seals vary, but all have a
lapped seal face between a stationary element and
a rotating seal ring (Ramsden, 1978). In a single
mechanical seal application, the rotating-seal ring
and stationary element faces are lapped to a very
high degree of flatness to maintain contact over their
shared surface area (Figure 3-2). The faces are held
together by a combination of pressure supplied by a
spring and the pump pressure transmitted through
the liquid that is being pumped. An elastomer seals
the rotating face to the shaft. The stationary face is
sealed to the stuffing box with another elastomer or
gasket. As with packed seals, the faces must be
lubricated: however, because of the mechanical
seafs construction, much less lubrication is needed.
Again, if the seal becomes imperfect because of
wear, the organic compounds being pumped can
teak between the seal faces and can be emitted to
the atmosphere.

3.1.3 Dual Mechanical Seals
Dual mechanical seals (Figure 3-3) can be arranged
back to back, in tandem, or face to face. In the back-
to-back arrangement, the too seals form a closed
cavity. A barrier fluid, such as water or seal oil, is
circulated through the cavity. Because the barrier
fluid surrounds the dual seal and lubricates both
sets of seal faces, the heat transfer and seal life
characteristics of this dual seal are much better than
those of the single seal. In order for the seal to
function, the barrier fluid "must be at a pressure
greater than the operating pressure of the stuffing
box. As a result, some barrier fluid will leak across
the seal faces. Liquid leaking across the inboard
face will enter the stuffing box and mix with the
process liquid. Barrier fluid going across the
outboard face will exit to the atmosphere. Therefore,
the barrier fluid must be compatible with the process
liquid and with the environment (Ramsden, 1978, p.
99).

-------
In a tandem dual mechanical seal arrangement, the
seals face the same direction, and the secondary
seal provides a backup for the primary seal. A seal
flush is used In the stuffing box to remove the heat
generated by friction. As with the back-to-back seal
arrangement, the cavity between the two tandem
seals is filled with a barrier fluid. The barrier fluid,
however, is at a pressure lower than that in the
stuffing box. Therefore, any leakage will be from the
stuffing box into the seal cavity containing the barrier
fluid. Since this liquid is routed to a closed reservoir,
process liquid that leaks into the seal cavity also will
be transferred to the reservoir. At the reservoir, the
process liquid could vaporize and be emitted to the
atmosphere. To ensure that VOCs or VHAPs do not
leak from the reservoir, the reservoir can be vented
to a control device.
Another arrangement of dual seals is face to face. In
this configuration, two rotating faces are mated with
a common stationary barrier. Barrier fluid may be
provided at higher or lower pressures than in the
stuffing box. As in the tandem arrangement, if the
barrier fluid is at a lower pressure than in the stuffing
box, the barrier fluid reservoir may require venting to
a control device.
3.1.4 Seal-less Pumps
The seal-less pump includes canned-motor and
diaphragm pumps. In canned-motor pumps (Figure
3-4), the cavity housing, the motor rotor, and the
pump casing are interconnected. As a result, the
motor bearings run in the process liquid and all shaft

seals are eliminated. Because the process liquid is
the bearing lubricant, abrasive solids cannot be
tolerated. Canned-motor pumps are used widely for
handling organic solvents, organic heat transfer
liquids, light oils, and many toxic or hazardous
liquids. Canned-motor pumps also are used when
leakage is an economic problem (Perry and Chilton,
1978, p. 6-8).
Diaphragm pumps (Figure 3-5) perform similarly to
piston and plunger pumps. The driving member,
however, is a flexible diaphragm fabricated of metal,
rubber, or plastic. The primary advantage of this
arrangement is that no packing and shaft seals are
exposed to the process liquid, which is an important
asset when handling hazardous or toxic liquids.

3.2 Compressors
In the industries affected by these standards,
centrifugal, reciprocating, and rotary compressors
are used. The centrifugal compressor uses a
rotating element or series of elements containing
curved blades to increase the pressure of a gas by
centrifugal force. Reciprocating and rotary
compressors increase pressure by confining the gas

in a cavity and progressively decreasing the volume
of the cavity. Reciprocating compressors usually use
a piston and cylinder arrangement, while rotary
compressors use rotating elements such as lobed
impellers or sliding vanes.
As with pumps, seals are required to prevent
leakage from compressors. Rotary shaft seals for
compressors may be labyrinth, restrictive carbon
rings, mechanical contact, or liquid film. Figure 3-6
is an illustration of typical designs of these four
types of seals. All of these seals are leak restriction
devices, but none of them completely eliminates
leakage. To respond to leakage, many compressors
are equipped with ports in the seal area that
evacuate collected gases.
3.2.1 Labyrinth
The labyrinth seal is composed of a series of close
tolerance, interlocking "teeth" that restrict the flow of
gas along the shaft. Many variations in "tooth*
design and materials of construction are available.
Although labyrinth seals as a group have the largest
leak potential of the different types, properly applied
variations in tooth configuration and shape can
reduce leakage by up to 40 percent over a straight-
pass-type labyrinth (Nelson, 1977).
3,2.2 Carbon Rings
Restrictive carbon ring seals consist of multiple
stationary carbon rings with close shaft clearances.
These seals may be operated dry with a sealing fluid
or with a buffer gas. Restrictive ring seals can
achieve lower leak rates than can the labyrinth type.
3.2.3 Mechanical
Mechanical contact seals are a common type of seal
for rotary compressor shafts and are similar to the
mechanical seals described for pumps. In this type
of seal, the clearance between the rotating and
stationary elements is reduced to zero, and oil or
another suitable lubricant is supplied to the seal
faces. Mechanical seals can achieve the lowest leak
rates of the types discussed here, but they are not
suitable for all processing.
3.2.4 Packed
Packed seals are used for reciprocating compressor
shafts. As with pumps, the packing in me stuffing
box is compressed with a gland to form a seal.
Packing used on reciprocating compressor shafts is
often of the "chevron" or netted V type. To ensure
operating safety, the area between the compressor
seals and the compressor motor (distance piece)
normally is enclosed and vented outside of the
compressor building. If hydrogen sulfide is present
in the gas, then the vented vapors are flared
normally.
Reciprocating compressors can use a metallic
packing plate and nonmetallic partially compressible
material (i.e., Graffbil, Teflon) or oil wiper rings to
seal shaft leakage to the distance piece.
Nevertheless, some leakage into the distance piece
may occur.
3.2.5 Liquid Film Seals
In addition to having seal types like those used for
pumps, centrifugal compressors can be equipped
with a liquid-film seal. The seal is a film oil that flows
between the rotating shaft and the stationary gland.
The oil that leaves the compressor from the
pressurized system side is under the system
internal gas pressure and is contaminated with the
gas. When this contaminated oil is returned to the
open oil reservoir, process gas and entrained VOCs
and VHAPs can be released to the atmosphere.
3.3 Pressure Relief Devices
Engineering codes require the use of pressure-
relieving devices or systems in applications where
Disc

EPA, 1990, p.2-16).
REGULATED EQUIPMENT
page D-5
-------
the process pressure may exceed the maximum
allowable working pressure of the vessel. The
pressure relief valve is the most common type of
pressure-relieving device used. Typically, relief
valves are spring-loaded (see Figure 3-7) and
designed to open when the system pressure
exceeds a set pressure, allowing the release of
vapors or liquids until the system pressure is
reduced to its normal operating level. When tfie
normal pressure is re-attained, the valve reseats,
and a seal is again formed. The seal is a disc on a
seat, and a leak through this seal is a potential
source of VOC and VHAP fugitive emissions. The
potential causes of leakage from relief valves are
"simmering or popping" (a condition that occurs
when the system pressure comes close to the set
pressure of the valve); improper reseating of the
valve after a relieving operation; and corrosion or
degradation of the valve seat (U.S. EPA, 1980a, p.
3-3).
Rupture discs also may be used to relieve pressure
fn process units (see Figure 3-8). These discs are
made of a material that ruptures when a set
pressure Is exceeded, thus allowing the system to
depressurize. The advantage of a rupture disc is
that the disc seals tightly and does not allow any

VOC or VHAP to escape from the system during
normal operations. When the disc ruptures,
however, the system will depressurize until
atmospheric conditions are obtained, unless the
disc is used with a pressure relief valve.
3.4 Sampling Connections
Process unit operations are checked periodically by
routine analysis of feedstocks and products. To
obtain representative samples for these analyses,
sampling lines first must be purged. If the flushing
liquid is not controlled, it could be drained onto the
ground or into a process drain where it would
evaporate and release VOCs or VHAPs to the
atmosphere. Closed-loop sampling systems control
the purged process fluid by returning it directly to
the process line, collecting and recycling the fluid, or
transporting tiie fluid to a control device. These
sampling system controls typically allow zero VOC
or VHAP emissions to the atmosphere. Two closed-
loop sampling systems are illustrated in Figure 3-9.

3.5 Open-ended Lines or Open Valves
Some valves are installed in a system so that they
function with the downstream line open to the
atmosphere. Open-ended lines, which are used
mainly in intermittent service for sampling and
venting, include purge, drain, and sampling lines.
Some open-ended lines are needed to preserve
product purity. Normally, these are installed
between multi-use product lines to prevent products
from collecting in cross-tie lines during valve seat
leakage. A faulty valve seat or incompletely closed
valve would result in leakage through the valve,
releasing fugitive VOC or VHAP emissions to the
atmosphere.
REGULATED EQUIPMENT
page D-6
-------
Operational requirements specify that open-ended
valves or lines be equipped with a cap, blind flange,
plug, or second valve. The purpose of the cap, blind
flange, plug, or second valve is to seal the open end
at all times, except during operations requiring
process fluid flow through the open-ended valve or
line.
If a second valve is used, the open-ended line or
valve is to be operated so that the valve on the
process fluid end is closed before the second valve
is closed. If a double block-and-bleed system is
being used, the bleed valve or line may remain open
during operations that require venting the line
between the block valves. At all other times, the
open end of the bleed valve or line must be sealed
(again, except during operations requiring process
fluid flow through the open-ended line or valve).
3.6 Process Valves
One of the most common pieces of equipment
affected by these standards is the process valve.
Commonly used types are control, globe, gate, plug,
ball, relief, and check valves (see Figures 3-10 and
3-11). All except the relief valve (see Section 3.3)
and check valve are activated through a valve stem,
which may have either a rotational or linear motion,
depending on the design. The valve stem requires
a seat to isolate the process fluid inside the valve
from the atmosphere. The possibility of a leak
through this seal makes it a potential source of
fugitive emissions. Since a check valve has no stem
or subsequent packing gland, it is not considered a
potential source of fugitive emissions.
The stem can be sealed to prevent leakage by using
a packing gland or O-ring seals. Valves that require
the stem to move in and out with or without rotation
must use a packing gland. Conventional packing
glands are suited for a wide variety of packing
material. The most common are various types of
braided asbestos that contain lubricants. Other
packing materials include graphite, graphite-
impregnated fibers, and tetrafluorethylene polymer.
The packing material used depends on the valve
application and configuration. These conventional
packing glands can be used over a range of
operating temperatures, but at high pressures, these
glands must be quite tight to obtain a good seal
(Templeton, 1971).

Figure 3-13. Diagram of a weir diaphragm seal
(U.S. EPA, 1990, p. 2-24).
Elastomeric O-rings also are used for sealing
process valves. These O-rings provide good
sealing, but are not suitable if sliding motion occurs
through the packing gland. These seals are used
rarely in high pressure service, and operating
temperatures are limited by the seal material.
Bellows seals are more effective for preventing
process fluid leaks than is the conventional packing
gland or any other gland-seal arrangement This
type of seal incorporates a formed metal bellows
that makes a barrier between the disc and body
bonnet joint (see Figure 3-12). The bellows is the
weak point of this type of system, and service life
can be quite variable. Consequently, this type of
seal normally is backed up with a conventional
packing gland and often is fitted with a leak detector
in case of failure.
A diaphragm may be used to isolate the working
parts of the valve and the environment from the
process liquid. Illustrated in Figures 3-13 and 3-14
are two types of diaphragm seals. The diaphragm
also may be used to control the flow of the process
fluid. In this design, a compressor component
pushes the diaphragm toward the valve bottom,
throttling the flow. The diaphragm and compressor
are connected in a manner so that separating them
is impossible under normal working conditions.
When the diaphragm reaches the valve bottom, it
seats firmly against the bottom, forming a leak-proof
REGULATED EQUIPMENT
page D-8
-------
seal. This configuration is recommended for fluids
containing solid particles and for medium-pressure
service. Depending on the diaphragm material, this
type of valve can be used at temperatures up to
2Q5°C and in severe acid solutions. If the seal fails,
however, a valve using a diaphragm seal can
become a source of fugitive, emissions (Pikulik,
1978, pp. 3-23 and 3-24).
3.7 Flanges and Other Connectors
Flanges are bolted, gasket-sealed junctions used
wherever pipes or other equipment such as vessels,
pumps, valves, and heat exchangers may require
isolation or removal. Connectors are all other
nonwelded fittings that serve a similar purpose to
flanges, which also allow bends in pipes (elbows),
joining two pipes (couplings), or joining three or tour
pipes (tees or crosses). Connectors typically are
threaded.
Flanges may become fugitive emissions sources
when leakage occurs because of improperly chosen
gaskets or poorly assembled flanges. The primary
cause of flange leakage is thermal stress, which
causes deformation of the seal between the flange
faces. Threaded connectors may leak if the threads
become damaged or corroded or if tightened without
sufficient lubrication or torque. LDAR programs are
the principal control technique for flanges and other
connectors.
3.8 Product Accumulator Vessels
The background information document for the
proposed benzene standards (U.S. EPA. 1980b)
states that product accumulator vessels include
overhead and bottoms receiver vessels used with
fractionation columns and product separator vessels
used in series with reactor vessels to separate
reaction products. Accumulator vessels can be
vented directly to the atmosphere or indirectly
through a blowdown drum or vacuum system. When
an accumulator vessel contains benzene and vents
to the atmosphere, benzene emissions can occur.
This equipment is covered only by the benzene
equipment leak standards.
The benzene standards require each product
accumulator vessel to be equipped with a closed-
vent system capable of capturing and transporting
any leakage from the vessel to a control device.
Acceptable control devices include vapor recovery
systems, enclosed combustion devices, or flares.
These control systems are described in Section
3.10.
3.9 Agitators
Agitators are used to stir or blend chemicals. Like
pumps and compressors, agitators may leak
organic chemicals at the point where the shaft
penetrates the casing. Consequently, seats are
required to minimize fugitive emissions. Four seal
arrangements commonly are used with agitators:
compression packing (packed seal), mechanical
seals, hydraulic seals, and lip seals. Packed seals
for agitators are very similar in design and
application to packed seals for pumps (Ramsey and
Zoller, 1976).
Although mechanical seals are more costly than the
other three types of seals, they offer a .greatly
reduced leakage rate to offset their higher cost.
Furthermore, the maintenance frequency of
mechanical seals is one-half to one-fourth that of
packed seals. At pressures greater than 1,140 kPa
(150 psig), the leakage rate and maintenance
frequency are so superior that the use of packed
seals on agitators is rare. As with packed seals, the
mechanical seals for agitators are similar in design
and application to the mechanical seals for pumps.
The hydraulic seal, which is the simplest and least
used agitator shaft seal, has an annular cup
attached to the process vessel that contains a liquid
that is in contact with an inverted cup attached to
the rotating agitator shaft. The primary advantage of
this seal is that it is a noncontact seal. Use of this
seal, however, is limited to low temperatures and
pressures and very small pressure fluctuations. In
addition, organic chemicals may contaminate the
liquid and then be released into the
atmosphere as fugitive emissions.
A lip seal can be used on a top-entering agitator as
a dust or vapor seal. The sealing element is a
spring-loaded elastomer. Lip seals are relatively
inexpensive and easy to install. Once the seal has
been installed, the agitator shaft rotates in
continuous contact with the lip seal. Pressure limits
of the seal are 2 to 3 psig because it operates
without lubrication, and operating temperatures are
limited by the characteristics of the elastomer.
Fugitive. emissions can be released through this
seal when the seal wears excessively or the

3.10 Closed-Vent Systems and Control
Devices
A closed-vent system can be used to collect and
dispose of gaseous VOC emissions from seal oil
degassing vents, pump -and compressor seal
leakage, relief valve leakage, and relief valve
discharges because of over-pressure operation. A
closed-vent system consists of piping connectors,
flame arresters, and, if necessary, flow-inducing
devices. Closed-vent systems are designed and
operated so that all VOC emissions are transported
to a control device without leakage to the
atmosphere.
Several types of control devices can be used to
dispose of VOC and VHAP emissions captured in
the closed-vent system. Incineration, carbon
adsorption, and condensation are three control
methods that typically are applied. Control
efficiencies of the three methods are dependent on
specific operating characteristics and the types of
emissions being generated. Typically, enclosed
combustion devices (boilers, process heaters, and
thermal and catalytic incinerators) can achieve
better than 95 percent destruction efficiencies. The
key parameters affecting destruction efficiency are
residence time and temperature. Carbon adsorption
systems can achieve 95 to 99 percent control
efficiency through proper design and operation,
white condensation systems can achieve capture
efficiencies of 90 percent or more.
Flares commonly found at plants subject to these
standards include steam-assisted, air-assisted, non-
assisted, ground, and dual-flare systems. Certain
flares have demonstrated destruction efficiencies
equal to those of enclosed combustion devices
provided certain design specifications (heat content
and exit velocity) are met (U.S. EPA, 1985).

EMISSION MEASUREMENT TECHNICAL INFORMATION CENTER
NSPS TEST METHOD
(EMTICM-21, 2/9/93)
Method 21 - Determination of Volatile Organic Compound Leaks
1. APPLICABILITY AND PRINCIPLE
1,1 Applicability. This method applies to the determination of volatile organic compound
(VOC) leaks from process equipment. These sources include, but are not limited to,
valves, flanges and other connections, pumps and compressors, pressure relief devices,
process drains, open-ended valves, pump and compressor seal system degassing vents,
accumulator vessel vents, agitator seals, and access door seals,
1.2 Principle. A portable instrument is used to detect VOC leaks from individual sources.
The instrument detector type is not specified, but it must meet the specifications and
performance criteria contained in Section 3. A leak definition concentration based on a
reference compound is specified in each applicable regulation. This procedure is intended
to locate and classify leaks only, and is not to be used as a direct measure of mass
emission rate from individual sources.
2. DEFINITIONS
2.1 Leak Definition Concentration. The local VOC concentration at the surface of a
leak source that indicates that a VOC emission (leak) is present, The leak definition is an
instrument meter reading based on a reference compound.
2.2 Reference Compound. The VOC species selected as an instrument calibration basis
for specification of the leak definition concentration. (For example, if a leak definition
concentration is 10,000 ppm as methane, then any source emission that results in a local
concentration that yields a meter reading of 10,000 on an instrument meter calibrated with
methane would be classified as a leak. In this example, the leak definition is 10,000 ppm,
and the reference compound is methane.)
2.3 Calibration Gas. The VOC compound used to adjust the instrument meter reading
to a known value. The calibration gas is usually the reference compound at a known
concentration approximately equal to the leak definition concentration.
2.4 No Detectable Emission. The total VOC concentration at the surface of a leak
source that indicates that a VOC emission (leak) is not present. Since background VOC
concentrations may exist, and to account for instrument drift and imperfect reproducibility,
a difference between the source surface concentration and the local ambient concentration
is determined. A difference based on the meter readings of less than a concentration
METHOD 21 (40 CFR 60, APPENDIX A) page E-1
-------
corresponding to the minimum readability specification indicates that a VOC emission
(leak) is not present (For example, if the leak definition in a regulation is 10,000 ppm, then
the allowable increase is surface concentration versus local ambient concentration would
be 500 ppm based on the instrument meter readings.)
2.5 Response Factor. The ratio of the known concentration of a VOC compound to the
observed meter reading when measured using an instrument calibrated with the reference
compound specified in the applicable regulation.
2.6 Calibration Precision. The degree of agreement between measurements of the
same known value, expressed as the relative percentage of the average difference
between the meter readings and the known concentration to the known concentration.
2.7 Response Time. The time interval from a step change in VOC concentration at the
input of the sampling system to the time at which 90 percent of the corresponding final
value is reached as displayed on the instrument readout meter.
3. APPARATUS
3.1 Monitoring Instrument.
3.1.1 Specifications
a. The VOC instrument detector shall respond to the compounds being processed.
Detector types which may meet this requirement include, but are not limited to, catalytic
oxidation, flame ionization, infrared absorption, and photoionization.
b. The instrument shall be capable of measuring the leak definition concentration
specified in the regulation.
c. The scale of the instrument meter shall be readable to + or - 5 percent of the specified
leak definition concentration.
d. The instrument shall be equipped with a pump so that a continuous sample is provided
to the detector. The nominal sample flow rate shall be 0.1 to 3.0 liters per minute.
e. The instrument shall be intrinsically safe for operation in explosive atmospheres as
defined by the applicable U.S.A. standards (e.g., National Electrical Code by the National
Fire Prevention Association).
f. The instrument shall be equipped with a probe or probe extension for sampling not to
exceed 1/4 in. in outside diameter, with a single end opening for admission of sample.
METHOD 21 (40 CFR 60, APPENDIX A) page E-2
-------
3.1.2 Performance Criteria.
a. The instrument response factors for the individual compounds to be measured must
be less than 10.
b. The instrument response time must be equal to or less than 30 seconds. The
response time must be determined for the instrument configuration to be used during
testing.
c. The calibration precision must be equal to or less than 10 percent of the calibration gas
value.
d. The evaluation procedure for each parameter is given in Section 4.4.
3.1.3 Performance Evaluation Requirements.
a. A response factor must be determined for each compound that is to be measured,
either by testing or from reference sources. The response factor tests are required before
placing the analyzer into service, but do not have to be repeated at subsequent intervals.
b. The calibration precision test must be completed prior to placing the analyzer into
service, and at subsequent 3-month intervals or at the next use whichever is later.
c. The response time test is required before placing the instrument into service. If a
modification to the sample pumping system or flow configuration is made that would
change the response time, a new test is required before further use.
3.2 Calibration Gases.
The monitoring instrument is calibrated in terms of parts per million by volume (ppm)
of the reference compound specified in the applicable regulation. The calibration gases
required for monitoring and instrument performance evaluation are a zero gas (air, less
than 10 ppm VOC) and a calibration gas in air mixture approximately equal to the leak
definition specified in the regulation. If cylinder calibration gas mixtures are used, they
must be analyzed and certified by the manufacturerto be within + or - 2 percent accuracy,
and a shelf life must be specified. Cylinder standards must be either reanalyzed or
replaced at the end of the specified shelf life. Alternatively, calibration gases may be
prepared by the user according to any accepted gaseous preparation procedure that will
yield a mixture accurate to within + or - 2 percent. Prepared standards must be replaced
each day of use unless it can be demonstrated that degradation does not occur during
storage.
Calibrations may be performed using a compound other than the reference compound
if a conversion factor is determined for that alternative compound so that the resulting
METHOD 21 (40 CFR 60, APPENDIX A) page E-3
-------
meter readings during source surveys can be converted to reference compound results.

4.4 if the evaluation requirement of Section 3.1.3 have not been met
4.2 Calibration Procedures. Assemble and start up the VOC analyzer according to the
manufacturer's instructions. After the appropriate warmup period and zero internal
calibration procedure, introduce the calibration gas into the instrument sample probe.
Adjust the instrument meter readout to correspond to the calibration gas value. (Note: If
the meter readout cannot be adjusted to the proper value, a malfunction of the analyzer
is Indicated and corrective actions are necessary before use.)
4.3 Individual Source Surveys.
4.3.1 Type I - Leak Definition Based on Concentration. Place the probe inlet at the
surface of the component interface where leakage could occur. Move the probe along the
interface periphery while observing the instrument readout. If an increased meter reading
is observed, slowly sample the interface where leakage is indicated until the maximum
meter reading is obtained. Leave the probe inlet at this maximum reading location for
approximately two times the instrument response time. If the maximum observed meter
reading is greaterthan the leak definition in the applicable regulation, record and report the
results as specified in the regulation reporting requirements. Examples of the application
of this general technique to specific equipment types are:
a. Valves - Leaks usually occur at the seal between the stem and the housing. Place the
probe at the interface where the stem exits the packing and sample the stem
circumference and the flange periphery. Survey valves of multipart assemblies where a
leak could occur.
b. Flanges and Other Connections - Place the probe at the outer edge of the flange-
gasket interface and sample the circumference of the flange.
c. Pump or Compressor Seals - If applicable, determine the type of shaft seal. Perform
a survey of the local area ambient VOC concentration and determine if detectable
emissions exist as described above.
d. Pressure Relief Devices - For those devices equipped with an enclosed extension, or
horn, place the probe inlet at approximately the center of the exhaust area to the
atmosphere.
e. Process Drains - For open drains, place the probe inlet as near as possible to the
METHOD 21 (40 CFR 60, APPENDIX A) page E-4
-------
center of the area open to the atmosphere. For covered drains, locate probe at the surface
of the cover and traverse the periphery.
f. Open-ended Lines or Valves - Place the probe inlet at approximately the center of the
opening of the atmosphere.
g. Seal System Degassing Vents, Accumulator Vessel Vents, Pressure Relief Devices -
If applicable, observe whether the applicable ducting or piping exists. Also, determine if
any sources exist in the ducting or piping where emissions could occur before the control
device. If the required ducting or piping exists and there are no sources where the
emissions could be vented to the atmosphere before the control device, then it is
presumed that no detectable emissions are present. If there are sources in the ducting or
piping where emissions could be vented or sources where leaks could occur, the sampling
surveys described in this section shall be used to determine if detectable emissions exist.
h. Access door seals - Place the probe inlet at the surface of the door seal interface and
traverse the periphery.
4.3.2 Type II - "No Detectable Emission". Determine the ambient concentration around
the source by moving the probe randomly upwind and downwind around one to two meters
from the source. In case of interferences, this determination may be made closer to the
source down to no closer than 25 centimeters. Then move the probe to the surface of the
source and measure as in 4.3.1. The difference in these concentrations determines
whether there are no detectable emissions. When the regulation also requires that no
detectable emissions exist, visual observations and sampling surveys are required.
Examples of this technique are: (a) Pump or Compressor Seals - Survey the local area
ambient VOC concentration and determine if detectable emissions exist, (b) Seal System
Degassing Vents, Accumulator Vessel Vents, Pressure Relief Devices - Determine if any
VOC sources exist upstream of the device. If such ducting exists and emissions cannot
be vented to the atmosphere upstream of the control device, then it is presumed that no
detectable emissions are present, if venting is possible sample to determine if detectable
emissions are present.
4.3.3 Alternative Screening Procedure.
4.3.3.1 A screening procedure based on the formation of bubbles in a soap solution that
is sprayed on a potential leak source may be used for those sources that do not have
continuously moving parts, that do not have surface temperatures greater than the boiling
point or less than the freezing point of the soap solution, that do not have open areas to
the atmosphere that the soap solution cannot bridge, or that do not exhibit evidence of
liquid leakage. Sources that have these conditions present must be surveyed using the
instrument technique of Section 4.3.1 or 4.3.2.
METHOD 21 (40 CFR 60, APPENDIX A) page E-5
-------
4.3.3.2 Spray a soap solution over all potential leak sources. The soap solution may be
a commercially available leak detection solution or may be prepared using concentrated
detergent and water.
A pressure sprayer or squeeze bottle may be used to dispense the solution. Observe the
potential leak sites to determine if any bubbles are formed. If no bubbles are observed,
the source is presumed to have no detectable emissions or leaks as applicable. If any
bubbles are observed, the instrument techniques of Section 4.3.1 or 4.3.2 shall be used
to determine if a leak exists, or if the source has detectable emissions, as applicable.
4.4 Instrument Evaluation Procedures. At the beginning of the instrument performance
evaluation test, assemble and start up the instrument according to the manufacturer's
instructions for recommended warmup period and preliminary adjustments.
4.4.1 Response Factor.
4.4.1.1 Calibrate the instrument with the reference compound as specified in the
applicable regulation. For each organic species that is to be measured during individual
source surveys, obtain or prepare a known standard in air at a concentration of
approximately 80 percent of the applicable leak definition unless limited by volatility or
explosivity. In these cases, prepare a standard at 90 percent of the standard saturation
concentration, or 70 percent of the lower explosive limit, respectively. Introduce this
mixture to the analyzer and record the observed meter reading. Introduce zero air until a
stable reading is obtained. Make a total of three measurements by alternating between
the known mixture and zero air. Calculate the response factor for each repetition and the
average response factor.
4.4.1.2 Alternatively, if response factors have been published for the compounds of
interest for the instrument or detector type, the response factor determination is not
required, and existing results may be referenced. Examples of published response factors
for flame ionization and catalytic oxidation detectors are included in the Bibliography.
4.4.2 Calibration Precision. Make a total of three measurements by alternately using
zero gas and the specified calibration gas. Record the meter readings. Calculate the
average algebraic difference between the meter readings and the known value. Divide this
average difference by the known calibration value and multiply by 100 to express the
resulting calibration precision as a percentage.
4.4.3 Response Time. Introduce zero gas into the instrument sample probe. When the
meter reading has stabilized, switch quickly to the specified calibration gas. Measure the
time from switching to when 90 percent of the final stable reading is attained. Perform this
test sequence three times and record the results. Calculate the average response time.

ABSTRACT
The purpose of this manual is to enhance an inspector's ability to conduct more
complete and effective inspections at facilities in the chemical industry that are subject
to Federal equipment leak regulations. Equipment leak standards are designed to reduce
or eliminate emissions of volatile organic compounds (VOCs), volatile hazardous air
pollutants (VHAPs), and organic HAPs from the miles of piping and numerous
components found in chemical manufacturing processes.
This document is divided into three volumes. The first volume is a manual for
inspectors; the second and third volumes describe regulations that apply to the chemical
manufacturing and the petroleum refining industries, respectively.
Volume I has five chapters dedicated to helping an inspector:
« Chapter 1 states the goals, background, approaches to rale enforcement, and
organization of the document.
• Chapter 2 addresses applicability determinations: ensuring the correct rales are
being complied with at a facility, determining whether all appropriate
components have been identified, and ensuring the components are properly
classified by service.
« Chapter 3 discusses reporting and recordkeeping requirements for NSPS,
NESHAP, HON, and RCRA (recordkeeping only), and strategies for reviewing
reports and records.
• Chapter 4 covers on-site inspections: walk-throughs and inspections with the
inspector monitoring for leaks. It addresses pre-inspection activities, timing and
scope, interviews, leak monitoring evaluations, inspections of the process area
and records, and post-inspection reviews and reports.
• Chapter 5 discusses recommended inspection techniques and procedures.
Volume BE tackles the equipment leak regulations applicable to the chemical
manufacturing industry.
• The first three appendices of Volume II summarize the regulations of 40 CFR
Part 60 Subpart W, Part 61 Subparts J and V, Part 63 Subparts H and I, Part
264 Subpart BB, and Part 265 Subpart BB; detail the differences among the
regulations; and give the requirements grouped by component.
• Appendix D describes the regulated equipment.
« Appendix E contains the "Method 21" approach to leak detection.
» Appendix F lists chemical manufacturing processes that are subject to HON.
• Appendix G lists organic HAPs that are subject to HON.
« Appendix H lists manufacturing processes and associated organic HAP
emissions that are subject to HON.
-------
Volume III contains the equipment leak regulations applicable to the petroleum refining
industry.
• The three appendices of Volume in summarize the regulations of 40 CFR Part
60 Subparts DDD, GGG, KKK, and QQQ, and Part 63 Subpart CC; detail the
differences among the regulations; and give the requirements grouped by
component.

demonstration
Equipment must be demonstrated not to be
in VOC service (i.e., VOC content never
greater than 10% by weight).
For demonstration:
Use procedures that conform to ASTM E-
260, E-168, E-I69 to determine percent
VOC in process fluid that is contained or
contacts a piece of equipment.
Engineering judgement may be used to
estimate the VOC content if piece of
equipment had not been shown previously
to be in VOC service.
Administrator will require use of ASTM
Method D-2267b in event of disagreement
to determine VOC content,
Compounds determined by EPA to have
negligible photochemical reactivity can be
excluded in determining VOC content of a
process fluid.
Equipment must be
demonstrated that
the percent VOC
content can be
reasonable expected
never to exceed
10.0 percent by
weight.
For demonstration:
Use procedures that
conform to ASTM
Methods El69,
E168,orE-260
(incorporated by
reference).
Not applicable.
Equipment is presumed to be in organic HAP service unless demonstrated that the
organic HAP content can never reasonably expected to exceed 5 percent by weight.
For demonstration:
Use Method 18 of 40 CFR Part 60, appendix A to determine percent organic HAP,
Engineering judgment may be used to determine percent organic HAP does not
exceed 5 percent.
Owner/operator may instead determine organic HAP content does not exceed 5
percent by weight.

Applicability Optional in Phase IH to owners/operations with a4% leakers without Section 63.649 connector
monitoring or aS% leakers with Section 63.649 connector monitoring
Decision required within first year of Phase HI
If rolling average of percent leakers is <4% (or 5%) for 2 consecutive quarters: 1) comply with
QIP, 2) monitor each valve quarterly or 3) comply with both QIP and monitor quarterly
If monitoring each valve quarterly cannot use QIP again if leak rate goes above 4% (or 5%); monthly
monitoring is required
Demonstration of
Further Progress
Collect data and maintain records as follows:
» maximum instrument reading observed in each monitoring
• classification of valve "gas or light liquid service"
• repair method used and instrument readings after repair (monitoring required at least once within
the first 3 months after the repair is completed)(ID tag on a leaking valve may be removed after
the valve successfully passes this monitoring period
Continue to collect data for as long as the process unit is in QIP
Demonstrate progress in reducing the percent leaking valves each quarter by at least:
• 10 percent (meaning that each quarter there is at least a 10 percent reduction in the percent
leaking valves from the preceding monitoring period)
• alternative quarterly percent reduction and to less than 4% (or 5%) within 2 years
The provisions for failure to meet the 10% reduction for 2 consecutive rolling averages are:
• a choice of monthly monitoring, or
• implementation of a QBP for technology review
Technology Data collection for as long as in QIP:
Review and » valve type and manufacturer, valve design, materials of construction, year installed, and packing
Improvement material
» service characteristics of the stream (e.g., operating pressure, temperature, line diameter,
eorrosivity)
• gas/vapor or light liquid service
* repair methods used and the instrument readings after the repair
Inspect all valves removed due to leaks to determine cause of failure and recommend design and
other changes to reduce leak potential
Analyze data to determine the services, operating and maintenance procedures, and valve designs or
technologies that have poorer and those that have better than average performance; the first analysis
shall be completed no later than 18 months after the start of the program, shall use a minimum of 6
months of data, shall be done yearly for as long as the process unit is in the QIP program

Visual: View entire cover surface and each cover opening in a closed, seal position for evidence of
defect that may affect ability to continue to operate with no detectable organic emissions.
Repair
Requirements
Repair as soon as practicable; no later than 15 calendar days after identification (45 days for tanks)
Delay of Repair
Delay of repair allowed if the repair is technically impossible without a complete or partial facility or
unit shutdown.
Repair to occur before the end of the next facility or unit shutdown.
Recordkeeping
Requirements
When leak detected (for each test of detectable emissions):
• date test performed
• background level measures
« maximum concentration
• waste management unit
« control equipment
• leak interface location where detectable emissions measured
» description of problem and the corrective action taken
• date the corrective action completed
For each visual inspection that identifies a problem that could result in benzene emissions:
• date of inspection
« waste management unit inspection
* control equipment location inspected
• description of problem
* corrective action taken
• date corrective action completed
