SUBJECT: Analysis of Emissions Reduction Techniques for Equipment Leaks

1. Purpose

This memorandum documents a general review a nd analysis of emissions reduction techniques

for equipment leaks. It reviews control alterna tives and estimates the costs and environmental

impacts for the alternatives identified.

2. Legislative Background

The Clean Air Act (CAA) requires the U.S. Envi ronmental Protection Agency (EPA) to review

promulgated standards periodically to ensure new source performance standards (NSPS) and

national emissions standards for hazardous ai r pollutants (NESHAP) reflect advances in

emissions reduction technology. Sp ecifically, Section 112(d)(6) of the Clean Air Act (CAA)

states that “[t]he Administrato r shall review, and revise as necessary (taking into account

developments in practices, processes, and cont rol technologies), emissi on standards promulgated

under this section no less often than every 8 years.” Sim ilarly, Section 111 (b)(1)(B) requires

EPA to review NSPS for a given source category every 8 years, a nd, if appropriate, revise such

standards. To facilitate these required reviews, EPA is evaluating key em ission sources that exist

across several source categories to provide a cons istent framework for regulating emissions from

these sources. This memorandum provides informati on that may be considered in the course of

conducting a technology review for equipment leak emissions from a specific source category in

the future.

3. Introduction

Equipment leak standards are designed to redu ce or eliminate emissions of volatile organic

compounds (VOCs), volatile haza rdous air pollutants (VHAPs), and organic hazardous air

pollutants (HAPs) from piping and equipment f ound in various manufacturing processes. Many

federal regulations have been written to minimi ze air emissions from equipment leaks. Currently,

most equipment leaks are defined within regul ations primarily on the basis of a detection

instrument that reads the airborne concentration of volatile organic carbons at a potential leak

point on a parts per million (ppm) ba sis or on the basis of visual observation of certain types of

equipment. Generally, if the leak exceeds the th reshold, or leak definition, of the applicable

# Technical Memorandum – Analysis of Emissi ons Reduction Techniques for Equipment Leaks

December 21, 2011

2 regulation, repair of the leaki ng equipment is required. This memorandum considers methods to

reduce emissions from equipment leaks and analy zes the impacts associat ed with these methods

(EPA, 1998).

4. Description of Emission Releases

Emissions from equipment leaks occur in the fo rm of gases or liquids that escape to the

atmosphere through many types of connection points ( e.g. , flanges, threaded fittings) or through

the moving parts of valves, pumps, compressors, pr essure relief devices, and certain types of

process equipment (EPA, 1998).

Pumps

Pumps are used extensively in chemical manufac turing facilities for moving fluids. The most

widely used pump is the centrifugal pump. Othe r types of pumps include positive-displacement,

reciprocating and rotary acti on, 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 th e atmosphere, all pumps, except the sealless type

(canned-motor and diaphragm), require a seal at the point where the shaf t 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.

Compressors

Centrifugal, reciprocating, and ro tary compressors are used in ch emical manufacturing facilities.

The centrifugal compressor uses a rotating elemen t or series of elements containing curved

blades to increase the pressu re of a gas by centrifugal for ce. Reciprocating and rotary

compressors increase pressure by confining the gas in a cavity and progr essively decreasing the

volume of the cavity. Reciprocating compressors usually use a piston a nd cylinder arrangement,

while rotary compressors use rotating elements such as lobed impellers or sliding vanes.

As with pumps, seals are required to prevent le akage from compressors. Rotary shaft seals for

compressors may be labyrinth, rest rictive carbon rings, mechanical c ontact, 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 se al area that evacuate

collected gases to a control device.

Pressure Relief Devices

Engineering codes require the use of pressure-rel ieving 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 wh en the system pressure exceeds a set pressure,

allowing the release of vapors or liquids until the system pressu re is reduced to its normal

operating level. When the normal pressure is re-a ttained, 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 improper

# Technical Memorandum – Analysis of Emissi ons Reduction Techniques for Equipment Leaks

3 reseating of the valve after a re lieving operation (which occurs when the system pressure comes

close to the set pressure of th e valve); and corrosion or degrad ation of the valve seat. Some

pressure relief devices can be vented to a closed vent system fo r emissions control.

Rupture discs also may be used to relieve pressu re in process units. Thes e 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 a nd 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 (and then remain open to the

atmosphere until the disk is replaced), unless the disc is used with a pressure relief valve.

Sampling Connections

Process unit operations are checked periodically by routine analys is of feedstocks and products.

To obtain representative samples for these analyses, sampling lines first must be purged. If the

flushed fluid is a liquid, it could be drained onto the ground or into a process drain where it

would evaporate and release emi ssions to the atmosphere. Gas streams could be purged directly

to the atmosphere. Closed-loop sampling systems c ontrol the purged process fluid by returning it

directly to the process line, co llecting and recycling the fluid, or transporting the fluid to a

control device.

Open-ended Lines

Some valves are installed in a system to functi on with downstream lines 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 need ed to preserve product

purity. Normally, these are installed between multi -use product lines to prevent products from

collecting in cross-tie lines during valveseat leakag e. A faulty valve seat or incompletely closed

valve would result in leakage through the valv e, releasing emissions to the atmosphere. As

described in section 5, a cap, plug, blind flange, or secondary valv e is used at the end of the

open-ended line to prevent those emi ssions from reaching the atmosphere.

Process Valves

One of the most common types of equipment include d in an equipment leak detection and repair

program is the process valve. Commonly used ty pes are control, globe, gate, plug, ball, relief,

and check valves. All except the relief valve and check valve ar e activated through a valve stem,

which may have either a rota tional or linear motion, depending on the design. The valve stem

requires a seal to isolate the pr ocess fluid inside the valve from the atmosphere. The possibility

of a leak through this seal makes it a potential source of fugitive emissions. A check valve

typically is not a potential source of fugitive em issions because it has no stem or packing gland;

however, some check valves have a hinge that pe netrates the valve housi ng, which is a potential

source of fugitive emissions.

The stem can be sealed to prevent leakage by usi ng 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. Packing materials

# Technical Memorandum – Analysis of Emissi ons Reduction Techniques for Equipment Leaks

December 21, 2011

4 include graphite, graphite-impregnated fibers, and tetrafluorethylene polymer. The packing

material used depends on the valve applicati on and configuration. Thes e conventional packing

glands can be used over a range of operating te mperatures, but at high pressures, these glands

must be tight to obtain a good seal.

Elastomeric O-rings also are used for seali ng process valves. These O-rings provide good

sealing, but are not suitable if sliding motion occurs through th e packing gland. These seals are

used rarely in high pressure service, and opera ting temperatures are limited by the seal material.

Bellows seals are generally thought to be more effective for prev enting process fluid leaks than

the conventional packing gland or other gland-seal arrangement. This type of seal incorporates

formed metal bellows that makes a barrier be tween the disc and body bonne t joint. The bellows

are the weak point of th is 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 pushes the diaphragm toward the valve bottom, throttling the flow. The

diaphragm and compressor are connected in a ma nner so that separating them is impossible

under normal working conditions. When the diaphrag m 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, this type of valve can be used at te mperatures up to 205°C and in severe acid solutions.

If the seal fails, however, a valve using a di aphragm seal can become a source of leaks.

Flanges and Other Connectors

Flanges are bolted, gasket-sealed junctions us ed wherever pipes or other components or

equipment (such as vessels, pumps, valves, a nd 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 pi pes (couplings), or jo ining 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. Th e primary cause of flange leakage is thermal

stress, which causes deformation of the seal be tween the flange faces. Threaded connectors may

leak if the threads become damaged or corroded or if tightened without sufficient lubrication or

torque (EPA Office of Compliance Chemical, Commercial Services, and Municipal Division,

1998).

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. C onsequently, seals are

required to minimize fugitive emissions. Four seal arrangements commonly are used with

# Technical Memorandum – Analysis of Emissi ons Reduction Techniques for Equipment Leaks

December 21, 2011

5 agitators: compression pack ing (packed seal), mech anical seals, hydraulic seals, and lip seals.

Packed seals for agitators are very similar in de sign and application to packed seals for pumps.

Although mechanical seals are more co stly than the other three types of seals, they offer a greatly

reduced leakage rate to offset their higher co st. Furthermore, the maintenance frequency of

mechanical seals is one-half to one-fourth that of packed seals. At pr essures greater than 1,140

kPa (150 psig), the leakage rate and maintenance fr equency 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.

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 operating conditions ( e.g. , composition, pressure, flow, etc. ). Valves and connectors are

the predominant type of equipment used in in strumentation systems; however, other types of

equipment may also be included in these systems. These components are ge nerally the source of

leaks from instrumentation systems as well as fl uid that is vented or discharged from the

analyzer or bypass lines.

Closed-Vent Systems

A closed-vent system can be used to collect and convey gaseous emissions from seal oil

degassing vents, pump and compressor seal leakag e, relief valve leakage, and relief valve

discharges because of over-pressure operation. A process or portion of a process also can be

enclosed, and the enclosure can be vented through a closed vent system. A closed-vent system

consists of piping; equipment su ch as connectors, open-ended lines , and valves; flame arrestors,

and, if necessary, flow-inducing devices. Closed-vent systems are designed and operated to

convey emissions to a control device. However, just like in process lines, equipment in a closed

vent system is a potential sour ce of emissions due to leaks.

5. Identification of Control Options for Equipment Leaks

There are two primary techniques for reducing equipment leak emissions: (1) modifying or

replacing existing equipment, and (2) implem enting a leak detection and repair (LDAR)

program. Modifying or replacing existing eq uipment is referred to as an “equipment

modification.” Controlling emissions by equipment modification is achieved by either installing

additional equipment that eliminates or reduces emissions, or replacing existing equipment with

sealless types. An LDAR program is a structured program to detect and repair equipment that is

identified as leaking (U.S. EPA Office of Air Quaility Planning and Standards, 1995).

Equipment Modification Control Alternatives

For each equipment type there are one or more e quipment modifications th at can be implemented

for emissions control. This sec tion reviews the modifi cation alternatives for different equipment

leak types.

6 Pumps

Equipment modifications for pump s include routing leaking vapors through a closed -vent system

to control or replacing the existing pump with a new pump that is designed with dual mechanical

seals or is a sealless type.

A pump with dual mechanical seals contains two seals betw een which a barrier fluid is

circulated. Depending on the design of the dual mechanical seal s, the barrier fluid can be

maintained at a pressure that is higher than the pumped fluid or at a pressure that is lower than

the pumped fluid. If the barrier flui d is maintained at a higher pressure than the pumped fluid, the

pumped fluid will not leak to the atmosphere. Th e control efficiency of dual mechanical seals

with a barrier fluid at a highe r pressure than the pumped fl uid is essentially 100 percent,

assuming both the inner and out er seal do not fail simultaneous ly. If the barrier fluid is

maintained at a lower pressure than the pumped fl uid, a leak in the inner seal would result in the

pumped fluid entering the barrier fluid. To pr event emissions of the pumped fluid to the

atmosphere, a barrier fluid reservoir system shoul d be used. At the reservoir, the pumped fluid

can vaporize ( i.e. , de-gas) and then be collected by a closed-vent system.

The actual emissions reduction achievable through use of dual mechanical seals depends on the

frequency of seal failure. Failure of both the inner and outer seal s could result in relatively large

releases of the process fluid. Pressure monitori ng of the barrier fluid may be used to detect

failure of the seals, allowing fo r a quick response to a failure.

Sealless pumps, when operating properly, will no t leak because the process fluid cannot escape

to the atmosphere. Sealless pumps are used primarily in processes where the pumped fluid is

hazardous, highly toxic, or very expensive, and wh ere every effort must be made to prevent all

possible leakage of the fluid. Under proper operating conditions, the control efficiency of

sealless pumps is essentially 100 percent; however , if a catastrophic failure of a sealless pump

occurs, there is a potential fo r a large quantity of emissions.

Compressors

Emissions from compressors may be reduced by collecting and controlling the emissions from

the seal or by improving seal performance. Shaf t seals for compressors are of several different

types--all of which restrict but do not eliminat e leakage. In some cases, compressors can be

equipped with ports in the seal area to evacuat e collected gases using a closed-vent system.

Additionally, for some compressor seal types, em issions can be controlled by using a barrier

fluid in a similar manner as described for pumps.

Pressure Relief Valves

Equipment leaks from pressure relief valves (PRV s) occur as a result of improper reseating of

the valve after a release, or if the process is op erating too close to the set pressure of the PRV

and the PRV does not maintain its seal. Emissi ons occurring from PRVs as a result of an

overpressure discharge are not considered to be equipment leak emissions. There are two

primary alternatives for contro lling equipment leaks from pressu re relief devices: use of a

rupture disk (RD) in conjuncti on with the PRV, or use of a closed-vent system. The control

# Technical Memorandum – Analysis of Emissi ons Reduction Techniques for Equipment Leaks

December 21, 2011

7 efficiency of the RD/PRV combination is assumed to be 100 percent when operated and

maintained properly.

A closed-vent system can be used to transport equipment leaks from a PRV to a control device.

However, the equipment leak control efficiency for a closed-vent system installed on a PRV may

not be as high as the control efficiency that ca n be achieved by installi ng a closed-vent system on

other equipment types. This is due to the difficu lty of designing an effi cient control device that

can handle both high and low flow emissions since emissions from pressure relief devices can be

either high during an overpressure incident or low when associated with equipment leaks.

Valves

Emissions from process valves can be eliminated if the valve stem can be isolated from the

process fluid. Two types of sealless valves are available: diaphragm valves and sealed bellows

valves. The control efficiency of both diaphrag m and sealed bellows va lves is virtually 100

percent. However, a failure of these types of valves has the potential to cause temporary

emissions much larger than thos e from other types of valves.

Connectors

In cases where connectors are not required for safety, maintenance, process modification, or

periodic equipment removal, emissions can be eliminated by welding the connectors together.

Open-Ended Lines

Emissions from open-ended lines can be contro lled by properly installing a cap, plug, or second

valve to the open end. If a second valve is insta lled, the upstream valve should always be closed

first after use of the valves to prevent the tra pping of fluids between the valves. Capping an

open-ended line has the potential to achieve nearly 100 percent control. However, monitoring

has shown that capped open-ended lines of ten leak due to improper installation.

Sampling Connections

Emissions from sampling connections occur as a result of purging the sampling line to obtain a

representative sample of the pr ocess fluid. Emissions from sampling connections can be reduced

by using a closed-loop sampling system or by collec ting the purged process fluid and transferring

it to a control device, back to the process, or for liquids, to a hazardous waste or other type of

treatment unit. The closed-loop sampling system is designed to return the purged fluid to the

process at a point of lower pres sure. A throttle valve or othe r device is used to induce the

pressure drop across the sample loop. The efficiency of a closed-loop system is assumed to be

100 percent. Alternatively, in some cases, sampling connections can be designed to collect

samples without purging the line. If such a samp ling connection is insta lled and no emissions to

the atmosphere occur when a sample is collected, then the control efficiency can be assumed to

be 100 percent (U.S. EPA Office of Air Quaility Planning and Standards, 1995).

Instrumentation Systems

Emissions from the connectors, valves, and othe r equipment in instrumentation systems can be

controlled using the same tech niques described above for such equipment in process lines.

# Technical Memorandum – Analysis of Emissi ons Reduction Techniques for Equipment Leaks

December 21, 2011

8 Emissions of material that is pu rged from the system can be cont rolled using the same types of

techniques as described a bove for sampling connections.

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. C onsequently, seals are

required to minimize fugitive emissions. Four seal arrangements commonly are used with

agitators: compression pack ing (packed seal), mech anical seals, hydraulic seals, and lip seals.

Packed seals for agitators are very similar in de sign and application to packed seals for pumps.

Leak Detection and Repair Program

An LDAR program is designed to identify piece s of equipment that are emitting sufficient

amounts of material to warrant reduction of the emissions through repair. Leak detection

methods can include sensory inspections ( i.e. , indications of leaks based on sight, sound, or

smell) or monitoring with portable organic vapor analyzers in accordance with Method 21.

Typically, Method 21 has been used to monitor e quipment in gas/vapor service and equipment in

contact with relatively volatile liquids. Sensory inspections are generally used for equipment in

contact with less volatile liquids ( i.e. , “heavy” liquid service). Thes e programs are best applied to

equipment types that can be repaired on-line, resulting in immediate emissions reduction, and/or

to equipment types for which equipment modifica tions are not feasible. An LDAR program is

best suited to valves and pumps, and can also be implemented for agitators and connectors.

For other equipment types, an LDAR program is not as applicable. Compressors are repaired in a

manner similar to pumps; however, because compressors ordinarily do not have a spare for

bypass, a process unit shutdown may be required for repair. Compre ssors are typically controlled

by seal systems that include a barrier fluid sy stem. Historically, open-ended lines have been

controlled solely by equipment modifications (be cause the modification is expected to achieve

100 percent emissions reduction). Emissions from sampling connections can only be reduced by

changing the method of collecting the sample (sin ce, by definition, equipment leak emissions are

the material purged from the line), and cannot be reduced by an LDAR program. Safety

considerations may preclude th e use of an LDAR program on pressure relief valves.

Many studies have been performed to estimate the control effectiven ess of a given LDAR

program for light liquid pumps, gas valves, light liquid valves , and connectors. The control

effectiveness is based on the re lationship between the percentage of equipment pieces that are

leaking and the corresponding average leak emissi on rate for all of the equipment. The main

factors in determining the control effectiveness are: (1) how a “leak” is defined, (2) the leak

frequency before the LDAR program is implemen ted, and (3) the final leak frequency after the

LDAR program is implemented. The leak definition (or action level) for a piece of equipment is

the screening value at which a “leak” is indicated if the instrument reading is equal to or greater

than that value. The leak frequency is the fractio n of equipment with screen ing values equal to or

greater than the leak definition (EPA, 1995).

9 New Control Technologies

No entirely new developments in methods for co ntrolling equipment leak emissions were found.

However, variations and advancements in exis ting technologies and pr actices that are not

currently required in existing EPA rules have been identified and are listed as follows.

• Optical gas imaging – Optical gas imaging devi ces offer the ability to monitor equipment

from a distance and identify leaks (of a suffici ent mass) from equipment within the line

of sight of the optical imager (Envi ron International Corporation, 2003).

• “Low leak” packings – Packing combinations for valves and gaskets for flanges that

significantly reduce emissions are in place in some facilities, particularly refineries.

Facilities and packing manufacturers have crea ted emission testing protocols for packings

in order to study and test their effectivene ss. One of these studies, performed by two

packing manufacturers, revealed that “[s]ev eral aspects of valv e design; including

tolerances, surface finish, stem straightness and the overall alignment of the stem, stem

nut and stuffing box were found to be contribut ing factors to either the failure and/or

success of a particular stem packing to meet the emission requirements.” These studies

have lead to advancements such as pack ing consisting of braided carbon filament end

rings that encapsulate an Inc onel wire mesh with three molded flexible graphite center

rings (Cornelsen, 2006).

Some packing manufacturers have begun marke ting packings as “low-leak” packing and

providing performance guarantees. Companies have also develope d in-house testing

programs to ensure that packings are suitable fo r site-specific applications and to evaluate

the performance of different materials (Reeves, 2011).

• Monitoring of new equipment – Some local governments require monitoring on types

equipment that have not been monitored in th e past. In some cases, this is based on data

collected since LDAR programs where first designed and implemented. For example,

inspection agencies have conducted monitoring of open ended valves and lines (OELs) at

numerous facilities and found OELs that are leaking due to improper installation of the

plugs and other control equipment (W ilwerding 2007, Loukeris 2006). Monitoring on

atmospheric PRVs for releases and leaks is also required by some local governments

(Douglas, 2005).

The South Coast Air Management Quality District (SCAQMD) requires continuous

monitoring of a percentage of atmospheric PR Ds at refineries by installing a monitoring

device capable of recording the duration of each release and quantifying emissions.

Wireless technology allows continuous m onitoring of PRDs and makes it easy for

operators to identify releases and leaks. Th ere are several monitoring devices that can be

used, including acoustic sensors and pressure/di fferential pressure sensors. These sensor

units communicate with a base radio that in terfaces with the existing control system

(Ellis, 2007).

10 6. Summary of Control Options Analyzed

For the purposes of this memorandum, the baselin e control option is a combination of leak

detection and repair (LDAR) program elements , equipment design standards, and performance

standards which were based on a review of th e requirements and appl icability of existing

regulations, including federal, st ate, and local rules. The base line leak detection and repair

program is equivalent to the requirements in the National Emission Standards for Equipment

Leaks--Control Level 1 (40 CFR part 63, subpa rt TT) and Standards of Performance for

Equipment Leaks of VOC in the Synthetic Organic Compound Manufacturing Industry for

which Construction, Reconstruc tion, or Modification Commenced After January 5, 1981 but

Before November 7, 2006 (40 CFR part 60, subpart VV) and represents the least stringent set of

requirements that apply to faciliti es that are currently subject to equipment leaks standards. Thus,

it is also considered to be the least stringent al ternative for a process unit or facility that is

currently not subject to standards. Table 1 summ arizes the requirements of the baseline for all

equipment.

11 In addition, this memorandum also analyzes seve ral alternative means of compliance. From the

baseline, independent alternatives for each comp onent type were developed and are summarized

in Table 2. This approach provides the abilit y to analyze the incremental costs and cost

effectiveness of each alternative individually, while still distributing cost s of certain activities

(such as the use of a monitoring instrument or a da tabase) that apply to, or can be used for, more

than one type of equipment. Furthermore, many of these alternatives match current regulatory

requirements for facilities subject to certain existi ng rules; these alternatives thus can also serve

as the baseline in analyses of nationwide impact s of regulatory alternatives for source-category

specific rules that referen ce the Uniform Standards.

# Note that the regulatory leak definit ion for pumps is 2,000 ppm; however, data collected at a leak definition of 1,000

ppm were often used in this analysis to represent pumps with a leak definition of 2,000 ppm.



# Additional Requirements for Open Ende d Lines and Pressure Relief Devices

In addition to the requirements in Table 2, this memorandum also analyses the incremental cost

of conducting annual instrument monitoring to demonstrate that the open-ended valve or line

operates with an instrument reading of less than 500 ppm above background ( i.e. , that the cap,

blind flange, plug, or second valve seals the ope n-ended valve or line at all times). It was

assumed that the annual monitoring would not pr ovide any additional emissions reductions since

the baseline requires OELs to be capped, but w ould result in additional monitoring and repair

costs. The costs of annual monitoring, includ ing repair of any leak s found, are included in

Section 8.

The impacts associated with wireless monitoring for PRDs were also analyzed in this

memorandum. It was assumed that no additional emissions reductions would occur from this

requirement, but it would result in additional capital costs. Wireless monitoring costs are

included in Section 8.

7. Impact Analysis

Model Facilities

To calculate cost estimates and emissions reduc tions for potential equipment leak requirements,

model plants were developed to represent equipm ent counts found at different types of chemical

and refining facilities. Six models were creat ed, three to represent chemical manufacturing

process units and three to re present petroleum refineries. These models allowed for the

# Models 1-3 represent a range of chemical ma nufacturing process units and are based on the

models used in the Final Impacts Analysis for Regulatory Options for Equipment Leaks of VOC

in the SOCMI (Parrish, 2007). These equipment counts en compassed a large ra nge of individual

process units at chemical manufacturing facilities . However, a facility with numerous process

units could have many times more pieces of equi pment than Model 3. Focus was placed on small

facilities since that size range is where the impact s are most likely to be more burdensome. When

impacts for Model 3 are reasonable, we can be certai n that they will also be reasonable for larger

facilities.

Models 4-6 represent different size refineries, from a simple topping refinery to a complex

refinery. The equipment counts presente d for small and large refineries in Locating and

Estimating Air Emissions from Sources of Benzene (EPA, 1998) were used to estimate the

number of pieces of equipment in each type of refinery process un it. Model 4, the topping

# Technical Memorandum – Analysis of Emissi ons Reduction Techniques for Equipment Leaks

13 refinery, was assumed to consist of one crude distillation unit. Except for PRV, the equipment

counts for that model are equal to the counts for a crude distillation unit at a small refinery in

Locating and Estimating Air Emissions from Sources of Benzene (EPA, 1998). The PRV counts

were estimated based on a summary of data collected through EPA’s Petroleum Refinery

Information Collection Request (ICR) (EPA, 2011).

Models 5 and 6 were developed using info rmation from the U.S. Energy Information

Administration (EIA) on the number of refineries in the U.S., thei r capacities, and the types of

processes at each (U.S. DOE, 2011). The EIA report includes production capaci ty of facilities in

barrels per day (bbl/d) and the downstream charge capacity of each plant divided into process

type (vacuum distillation, dela yed coking, fluid coking, visbreaki ng, and other processes). Since

Locating and Estimating Air Emissions from Sources of Benzene defines the “large model

refinery” as a refinery with a crude charge capacity greater than 50,000 barrels per stream day,

refineries were classified as “large” or “small” based on the capacity in the EIA report. The

number of each type of process at an average “small” refinery and an average “large” refinery

was estimated based on the data in the EIA re port. For example, the EIA report included 40

“small” refineries, 24 of which reported vacuum di stillation capacity. Ther efore, it was assumed

for purposes of developing a small refinery model that an average small refinery has 0.6 vacuum

distillation units. Finally, the number of each type of process was multiplied by the appropriate

equipment counts in Locating and Estimating Air Emissi ons from Sources of Benzene , and the

results were summed for each type of equi pment except for PRV. The PRV counts were

estimated based on a summary of data from the Petroleum Refinery ICR. References for model

facilities are included in attachment 1.

The goal was to develop models as representative of the potential affected sources as possible so

that the model plants can be used in the futu re to develop source cate gory-specific nationwide

impact estimates in an efficient manner. There are process units and facilities larger than the

largest model; however, these models are intende d to cover a range of sizes representing a

majority of the potential affect ed facilities. In addition, the opt ions considered for the Uniform

Standards that are affected by economies of scale will have a greater impact on smaller processes

than larger processes. These models can be ad justed as needed based on data for a specific

source category or industry to represent that source category or indus try more accurately.

Leak Frequencies

Leak frequency refers to the estimated percenta ge of equipment that will be found leaking at a

given leak definition. Leak frequencies were used to calculate both cost and emission estimates

and are included in Table 4 and 5. Leak freque ncies were estimated using several sources

including the Protocol for Equipment Leak Emissi ons Estimates and industry data. Attachment 2

includes the basis for the leak frequencies in Ta bles 4 and 5. Detailed information on how leak

frequencies were used in cost and emission estim ates is included in the following sections.

# U.S. EPA National Enforcement Inve stigations Center (NEIC) data on leak frequencies for valves at refineries

suggest the actual percentage leaking may be higher. In orde r to account for this, it was estimated that the actual

percentage leaking is 1.7 times higher than typically m easured leak frequencies. This factor represents the 10th

percentile of the data set ( i.e. , 90 percent of the NEIC leak frequencies were at least 1.7 times higher than the leak

frequencies reported by the refineries) and was used determining leak frequencies (Parrish et al. , 2007).

15 Emission Reductions

In order to calculate the emissi ons reductions that result from th e baseline requirements, we first

had to estimate uncontrolled em issions. Once the emissions reductions of the baseline were

found, the incremental emissions reductions of each control alternative we re also calculated. The

incremental emissions reductions of each option is incremental w ith respect to the previous

option for a given equipment type. For example, the emissions reduction for pumps Option 1 is

based on the additional emissions reductions of Option 1 with respect to the baseline pump

emissions; similarly, the emissions reduction of pumps Option 2 is based on the additional

emission reduction of Option 2 with respect to Option 1. The following sections describe how

these emissions were calculated.

The first step in calculating emissions was to es tablish emission factors for each equipment type.

Emission factors are the estimated leak rates of an equipment type at a given leak definition and

are normally given in kg/hr/piece of equipment. Tables 6 and 7 summarize the leak emission

factors used for Models 1-3 and 4-6, respectively. Attachment 3 includes detailed information on

the basis for these emission factors.Technical Memorandum – Analysis of Emissions Reduction Techniques for Equipment LeaksDecember 21, 201116Table 6.

18 Uncontrolled emissions were calculated by multiplying the emission factors in Tables 6 and 7,

the equipment counts of each model, and the ope rating hours (which were assumed to be 8,760

hours/yr). Uncontrolled emissions for each mode l are summarized in Table 8. Attachment 4

provides detailed calculations.

Model 6 941,000 471



# Once uncontrolled baseline emissions were estab lished, emission estimates were calculated for

the baseline. The leak definitions under the ba seline are 10,000 ppm for pumps LL, valves G/LL,

and agitators in G/LL. Therefore, the leak emission factors for the baseline (summarized in Table

6 and 7) for these equipment types are based on a leak definition of 10,000 ppm. These leak

emission factors were multiplied by the equipment counts for each model and 8,760 hours to get

annual emissions. As stated in Section 5, the efficiency of the control methodologies for

sampling connections and PRVs in gas service is expected to be 100 percent; therefore,

implementing the requirements of the baseline for these types of equipment results in essentially

zero emissions for those equipment types. Emi ssion reductions from sensory requirements were

assumed to be zero because we are unable to quantify emissions reductions associated with

sensory requirements. Baseline compressor vent emissions estimates are based on emission

factors used in the HON analysis (Whitt, 1991), assuming the seal system barrier fluid would be

routed to a reservoir where the fluid could degas and the vapors routed to a control device. For

OELs, we used the emissions factors documented in previous analyses (Parrish and Randall,

2007; Parrish et al. , 2007) at the leak frequencies descri bed earlier in this section. Table 9

summarizes baseline emissi ons for all model plants.

# 8. Control Costs

The cost analysis uses a methodology that was originally presented in Impacts from the Control

of VHAP Emissions from Equipment Leaks in Non-SOCMI Process Units for HON (Whitt,

1991). The methodology has been tailored specifically for this analysis. Seve ral constant values

used in this analysis were developed for previ ous analyses and are deta iled in this section.

Cost calculations can fall into three categories:

1. Monitoring and Equipment Costs

2. Leak Repair Costs

3. Planning and training Costs

The first step was to estimate the costs of implementing the baseline. Once this was completed,

the incremental cost of each alternative was ca lculated. This section will analyze each cost

estimates and summarize the costs for each option.

Labor Hour Rates

Wage rate estimates used to calculate costs we re based on data from the U.S. Department of

Labor, Bureau of Labor Statistics for genera l manufacturing sectors (Sectors 31, 32, and 33)

(BLS, 2010). Overhead factors and fringe benefits were added to labor rates when necessary.

Table 11 summarizes the wage rates and overhead fact ors used to estimate costs for each option.

# Monitoring and Equipment Modification Costs

Initial monitoring costs are considered capital costs and are higher than annual monitoring costs

in order to account for implementation. They are incurred once at the st art of the program and

were calculated by multiplying the equipment count s in a given model by an estimated initial

monitoring fee. Table 12 summarizes the monitoring fees for each equipment type and the basis

for each.

# Monitoring instrumentation is also necessary for Method 21 monitoring, as well as a data

collection system to store mon itoring records. Instrumentation and data collection systems are

capital costs that were estimated at $10,800 a nd $14,500, respectively, per f acility. The estimated

instrumentation costs are roughly equal to the cost to purchase a st andard TVA1000B flame

ionization detector (FID)-only monitor with prob e from Thermo Fisher Scientific (2011). The

data collection system cost was based on Revised MACT Floor, Regulatory Alternatives, and

Nationwide Impacts for Equipment Leaks at Chemical Manufacturing Facilities (Shine et al.

, 2003).

Initial costs for PRD wireless monitoring device capable of identifying and recording the time

and duration of each pressure release and calculati ng the quantity of regulated material released

were also analyzed in addition to the baseline PRD requirements. There are several types of

wireless monitoring systems and costs vary de pending on the number of PRDs at a facility.

Based on cost studies from a SCAQMD staff repor t, the estimated cost of wireless monitoring

was assumed to be 7,500 dollars per PRD (the midpoint of the range provided by Ellis (2007),

which includes device parts, installation, maintenance, and da ta retrieval system. Annual

operating costs were not included in this analys is because they are assumed to be minimal.

Because the cost of electronic monitoring is not li near and facilities requ iring a large number of

monitors will benefit from economies of scale, the sixth-tenths rule was applied to calculate

initial costs which are provided below (Ellis, 2007).

# Technical Memorandum – Analysis of Emissi ons Reduction Techniques for Equipment Leaks

December 21, 2011

24 Leak Frequency and Repair Costs

The control options summarized in Tables 1 a nd 2 require Method 21 mon itoring and repair of

leaks for certain equipment types. Repair costs are a function of the leak frequency of a given

equipment type. An initial leak frequency repres ents the equipment found to be leaking the first

time the monitoring is conducted usi ng a particular leak definition. Th e cost to repair these initial

leaks is considered as initial LDAR costs (along with initial monitoring fees). The subsequent

leak frequency represents the equipment found to be leaking after a few monitoring cycles have

been completed and the program reaches “steady st ate” the cost to repair subsequent leaks are

considered annual repair costs. Generally, the subsequent leak fr equency is estimated to be less

than the initial leak frequency, but in some cases they are assumed to be the same. For example,

the initial leak frequencies for the baseline are the estimated percen tages of uncontrolled

equipment leaking above the 10,000 ppm leak defin ition, and the subsequent leak frequencies are

the estimated percentage of “leakers” once the ini tial leaks are repaired and the requirements are

in place. If initial or subseque nt leak frequencies increase for a control alternative, the initial

LDAR costs or the annual repair costs can increas e because there are more leaks to repair; these

additional repair costs are considered increm ental costs for each alternative option. Leak

frequencies were estimated using several source s including the Protocol for Equipment Leak

Emissions Estimates and industry data. As previous ly stated, attachment 2 includes the basis for

the leak frequencies in Tables 4 and 5.

The cost to repair initial and subsequent leak s is also based on whether the repair can be

performed online and the number of hours required to repair the leak. The general manufacturing

sector - Installation, Maintenance, and Repair Occupations labor rate with the overhead factor

applied ($66.24/hr) was used for all repairs. Tabl e 15 includes the assumptions used to estimate

the cost of repairing leaks and attachment 5 provides detailed cost calculations.

# As part of the initial (LDAR) repa ir cost for pumps we assumed th at the seals would need to be

replaced. The cost to purchas e replacement pump seals was estimated to be $282.71/leaking

pump (updated from Hausle, 1992); therefore, initia l LDAR cost for pumps also includes the cost

of replacement pumps seals multiplied by the number of initial leaks (in addition to the initial

monitoring and repair costs). The annual cost of pump replacements is included as an annual

25 maintenance cost. Leak repair costs also include additional monitoring of the repaired leaks in

order to verify the equipment was completely fi xed. These costs are considered annual costs and

were calculated using the subsequent monitoring fee for the equipment type and the subsequent

number of equipment leaking.

Baseline cost estimates for OELs only include the costs related to in stalling caps and annual

maintenance and do not include any OEL repair co sts. OEL repair costs were only used when

calculating incremental cost of annual monitoring on OELs (see Table 17).

Maintenance and Miscellaneous Costs

For pumps and agitators, annual maintenance co sts were included and are based on the annual

number of leaks multiplied by the updated co st of a replacement seal, $282.71 (Hausle, 1992).

Annual maintenance costs were also include d for PRVs, OELs, sampling connections, and

compressor vents as a percentage of initial monitoring fees. For PRV disk holders, OELs,

sampling connections, and compressor vents, annua l maintenance costs were based on 5 percent

of initial monitoring costs and 2 percent of initial monitoring costs for PRV disks.

Annual miscellaneous costs were also included in this analysis fo r pumps, PRDs, OELs,

sampling connections, and compressor vents. For pumps and agitators, th e miscellaneous costs

are based on 80 percent of the annual maintenance costs. For PRDs, OELs, sampling connections

and compressor vents, the annual miscellaneous charges are estimated using 4 percent of initial

monitoring costs (Hausle, 1992).

Administrative, Reporting, Planning, and Training Labor Costs

Planning and training costs are initial costs asso ciated with the implem entation of an LDAR

program. These costs include initial review of requirements and training of facility personnel.

We estimated initial planning and training costs based on an estimate of 320 labor hours and a

labor rate of $92.72/hr. The value of 320 hours per process unit is based on an estimate of initial

administration, planning, and training to implement a SOCMI-based LDAR program (Meardon,

1998). Planning and training costs we re included in baseline estimates, and it was assumed that

no additional planning and training costs would be incurred with any of the alternative options

for pumps and valves ( i.e. , incremental costs of planning and tr aining was assumed to be 0 for all

alternative options). For connectors, it was assumed that an additional 20 hours would be

required for activities such as adding connectors to the LDAR database for instrument

monitoring.

Annual reporting and administra tive costs were estimated usi ng 250 hours at a labor rate of

$92.72/hr to account for preparation of annual repor ts and recordkeeping. The 250 hour estimate

was based on the ratio of the amount of hours required for LDAR programs with and without

connectors which is estimated at 8 people at 32 hours each in Equipment Leak Analysis for

Amino and Phenolic Resins NESHAP (Meardon, 1998). Development of the labor rate is

discussed in Table 11. Annual repo rting costs were included in baseline estimates and it was

assumed that no additional annual reporting costs w ould be incurred with a ny of the alternative

options for pumps and valves ( i.e. , incremental costs of planning and training was assumed to be

$0 for all alternative options). For connectors, it was assumed that an additional 50 hours would

26 be required for preparation of annual reports and recordkeeping on ce the LDAR program

included instrument monitoring for connectors.

Annualized Initial Costs

Initial capital costs and labor expenditures were annualized using capital recovery factors. The

following equation was used to calculat e capital recovery factors (EPA, 2002):

CRF = [i * (1+i) n 

# )] / [(1+i) n 

# – 1],

Where, i is the interest rate and n is the life span in years.

For pump seals and rupture disks, the capital re covery factor is 0.244, as suming a life span of 5

years. For all other equipment types, the capital recovery factors is 0.142 based on a life span of

10 years. We also annualized initial repair la bor and planning and traini ng costs over 10 years.

For both factors, an interest ra te of 7 percent was used. The impacts analysis also includes a

recovery credit for the material that is not lost as emissions from equipment leaks. As in the

Technology Review for Heat Exchange Systems (Coburn, 2011), these cred its are $500/ton VOC.

Incremental Costs

Once the total initial and annual costs for th e implementation of baseline requirements was

determined, the incremental annual cost of each alternative option was estimated. Similar to

incremental emissions reductions, incremental cost s are the additional costs of the option with

respect to the preceding option. The incremental co sts were based on the additional repair costs

(initial and subsequent) of the lower leak definition of a given alternative option and any

additional costs that are calcu lated as a function of leak s (maintenance costs, annual

miscellaneous charges, and monitoring costs to veri fy off line repairs). It was assumed that there

are no incremental costs associated with monito ring fees, administrative costs, and planning and

training (except as described for connectors) si nce these are constant and should not increase

with a lower leak frequency. Detailed incremental cost calculations are included in attachment 5.

Cost estimates are summarized in Table 16 and Ta ble 17. Detailed cost calculations are included

28 9. Cost Effectiveness

The cost effectiveness of base line is calculated by dividing th e total annual costs (including

recovery credits) by the total emissions reduction of the baseline. Similarly, incremental cost

effectiveness was calculated by dividing the increm ental cost of each option (including recovery

credits) by the incremental emissions reductions. Tables 19-22 summarize the cost effectiveness

of each control alternative an alyzed in this memorandum.

Additional requirements for wireless monitoring for PRDs and annual monitoring of OELs were

not included in the cost effectiveness summary since no emissions reductions from these

activities is expected.

# Step 1: Calculate the LKFRAC % @ 10,000 ppm using 1,000 leak definition

ALR @ 1,000 ppm (kg/hr/source) = Equation 1

(0.11 × LKFRAC @1,000 ppm) + 4.6E-04 Table 5-4 Equipment Leak Protocol

LKFRAC @ 1,000 ppm = Equation 2

(NEIC Factor x 1.9 % Initial Leak Rate of Pumps LL @ 1,000ppm)/100

Substitute the leak frequency back into Equation 1.

ALR @ 1,000 ppm (kg/hr/source) =

0.11 × (NEIC Factor x 1.9 % Initial Leak Rate of Pumps LL @ 1,000ppm)/100 × 4.6E-04

ALR @ 10,000 ppm (kg/hr/source) = Equation 3

(0.24 × LKFRAC @ 10,000 ppm) + 1.9E-03 Table 5-4 Equipment Leak Protocol

Rearrange Equation 3 and substitute ALR@ 10,000 ppm with ALR at 1,000 ppm

LKFRAC % @ 10,000 ppm =

[(ALR @ 1 000 ppm (kg/hr/source)

- 1 9E

- 03 )/0 24] × 100

# LKFRAC % @ 10,000 ppm =

[(ALR @ 1,000 ppm (kg/hr/source) - 1.9E-03)/0.24] × 100

Substitute Equation 3 into Equation 4

LKFRAC % @ 10,000 ppm = Equation 4

[(0.11 × (((NEIC Factor x 1.9 % Initial Leak Rate of Pumps LL @ 1,000ppm)/100 × 4.6E-04) - 1.9E-03)/0.24] × 100

Step 2: Calculate the LKFRAC % @ 10,000 ppm using 5,000 leak definition
