smarter) greener) better"
Based in Las Vegas, Nevada, Southwest Gas Corporation (Southwest) provides natural gas
service to more than 1.8 million residential, commercial, and industrial customers in Arizona,
California, and Nevada. A Natural Gas STAR Partner since 1997, Southwest continues to
research, support, and implement new technologies that reduce methane emissions, energy
usage, and other environmental impacts. Because the company's operations have historically
grown at a rapid pace, new construction provided Southwest opportunities to avoid methane
emissions, to seek out methane savings in existing infrastructure, and relate methane emission
reductions to additional types of efficiency-improvement activities.
In addition to implementing technologies that reduce methane emissions from its gas
distribution network, Southwest actively participates in Natural Gas STAR as part of its overall
Smarter Greener Better resource conservation and energy-efficiency philosophy. As a result of
its ongoing efforts, the company received Outstanding Partner and Continuing Excellence
awards in 2005, 2007 and 2009. Recent Natural Gas STAR activities include greenhouse gas
(GHG) inventory development and participation in Gas Technology Institute (GTI) studies to
improve methane emission factors. In addition, the company has actively pursued pipe
replacement, minimizing compressor blowdowns, and tying Program participation to additional
GHG initiatives.
Developing a GHG Inventory
In 2004, Southwest was encouraged by the California Public Utilities Commission to inventory
GHG emissions from its California facilities. Southwest has since voluntarily expanded this
inventory corporate-wide to include emissions from all of its facilities including those in Arizona
and Nevada. The inventory followed the Natural Gas Reporting Protocol proposed by the
American Gas Association and adopted by the state of California.
The inventory has allowed Southwest to understand its carbon footprint and to develop
strategies specific to GHG emissions management. The inventory also allowed Southwest to
verify that many of its existing equipment and operating practices—such as newer polyethylene
pipe, leak detection, and minimizing blowdown volumes—are state-of-the-art in terms of low
methane emissions.
Participating in GTI Studies
To help improve the accuracy of emission factors, Southwest partnered with GTI to conduct
direct measurement of natural gas emissions from regulator stations and meters in Las Vegas
and Phoenix. Three other utilities have participated in the same study. Most recently,

-------
Southwest installed a custom pipe
array adjacent to the company's
new Emergency Response Facility
in Henderson, Nevada, to help GTI
initiate a study to improve the
accuracy of emission factors
currently used for calculation of
GHG emissions from buried pipes.
As a result of measuring actual
leaks from its regulator stations,
Southwest demonstrated that its
current emission rates were lower
than those measured during
similar studies done by GTI in the
early 1990s for older infrastructure
located throughout the United
States and Canada. As the
number of customers doubled over
the past decade due to new housing, Southwest's system has expanded and has used newer
materials with lower average leak rates.
Methane Emissions Reductions
In addition to the benefits of using materials with lower average leak rates in new construction,
Southwest has also been replacing pipe in older parts of its system. Over the past 13 years,
Southwest has reduced emissions by replacing some of its older steel and vintage plastic pipe
(early forms of plastic pipe) with newer polyethylene pipe. As a result, it has reduced emissions
from leaks by approximately 50 percent.
For the pipe in its distribution system, Southwest also maintains leak detection and repair
programs that require immediate repair of grade 1 leaks; repair of grade 2 leaks normally within
30 days of discovery; and repair or reevaluation of grade 3 leaks within 15 months of discovery.
While hazardous grade 1 leaks are repaired immediately by all utility companies, Southwest has
chosen to adopt time periods for the repair or reevaluation of non-hazardous grade 2 and non-
hazardous grade 3 leaks that are more aggressive than the published industry guidelines.
Southwest's leak detection methods include handheld walking and vehicle-mounted systems
with verification of buried pipe leak locations using handheld devices. Southwest's existing leak
detection and repair program to reduce methane emissions has also positioned the company for
the recently implemented U.S. Pipeline and Hazardous Materials Safety Administration's
(PHMSA) Integrity Management Programs, which require active repair of existing and potential
leaks as well as active leak management and review.
In addition to the focus on its buried pipe network, Southwest is also identifying and reporting
methane emissions reduction projects in other areas. Southwest and its subsidiaries operate
one natural gas liquefaction facility and seven compressor stations. At one compressor station,
Southwest is in the process of reconfiguring unit valve placement. By moving the valves closer
to the compressor suction and discharge, Southwest will be able to reduce the volume of natural
gas emissions from 21,500 cubic feet to 1,400 cubic feet during compressor blowdowns prior to
each routine maintenance activity. Southwest is reporting this as a voluntary Natural Gas STAR
activity and has considered deriving additional value from the avoided emissions through the
carbon market.

Natural Gas STAR as Part of Broader Climate Protection Strategy
These Natural Gas STAR projects are one aspect of Southwest's Smarter Greener Better
attitude in day-to-day operations and in forward planning. In addition to methane emissions
reductions in its system, Southwest also emphasizes efficiency measures, some of which are
highlighted below.
•	Southwest's Energy Efficient

researches and develops
commercially viable products
that reduce overall greenhouse
gas emissions, which has
included natural gas air
conditioning/heating. Two such

A newly developed high efficiency natural gas heat
pump, shown here at Davis Monthan Air Force
Base, is now available for commercial applications.
Southwest Gas has used Natural Gas STAR as a means to avoid or reduce methane emissions
while expanding its operations, and to complement its ongoing efforts to improve environmental
performance and increase efficiency.
Technology Spotlight
Scroll Compressors
Until recently, scroll compressors were considered only for special cases of vapor recovery
because of their low discharge pressure and limited capacity. Now designs with higher
discharge pressures are finding applications in the vapor recovery industry.
Since 1990, vapor recovery units (VRUs) have saved Natural Gas STAR Partners nearly 97
billion cubic feet (Bcf) of natural gas, worth $679 million when valued at $7 per thousand cubic
feet (Mcf) and millions more in natural gas liquids.
Typical compressor types for VRU implementations
have been rotary vane, rotary screw, or, less
frequently, reciprocating.
Rotary vane compressors have relatively small
capital costs and low energy consumption, but their
limited discharge pressures and frequent
maintenance limits their scope to high recovery and
low pressure differential vapor recovery projects.
Rotary screw compressors are selected for VRU

applications because of their moderate capital costs, lower maintenance costs, ability to handle
wet gas, and higher discharge pressures, but they still require frequent maintenance and have
higher energy consumption. Large recovery projects of dry gas requiring high discharge
pressures lend themselves to reciprocating compressors; however, these have poor
performance handling wet gas and require frequent maintenance.
One company, Emerson, has taken steps to improve on scroll compressors' shortcomings for
this application. It has expanded flow capacity by 30 percent flow increase and raised
discharge pressure by up to 350 pounds per square inch gauge in their Copeland Scroll™
compressor series. Natural Gas STAR Partners have reported using these compressors in their
vapor recovery applications.
The Copeland Scroll™ compressor has one scroll, or spiral, orbiting in a path defined by a
matching fixed scroll, as shown in Exhibit 1. The fixed scroll is attached to the compressor
body. The orbiting scroll is coupled to the crankshaft and orbits, rather than rotates. The
orbiting motion creates a progressively shrinking cavity between the two scrolls. On the outer
portion of the scrolls, the cavity draws in gas, and then pushes it to the center of the scroll,
where the gas is discharged. As the gas moves into
the increasingly smaller inner cavities, the
temperature and pressure increase to the desired
discharge pressure.
Their operating characteristics put scroll
compressors in competition with rotary vane and
rotary screw compressors, while reciprocating
compressors are used for larger projects on dry gas
with high discharge pressure. Scroll compressors
are more expensive to purchase than similarly sized
rotary vane and rotary screw compressors and are
limited in application to areas that have electrical
power. However, their unique design offers several
benefits over conventional vapor recovery
	 compressors:
•	Variable frequency drive
o Allows for easier adjustment to fluctuating vapor volumes
o Allows for compressor to run 99% of the time, providing greater recovery volumes.
•	Low maintenance
o Estimated one hour annually
o Requires only oil change and replacement of two filters, but does not require alignment
or valve replacement
•	Very low noise levels make it an option for heavily populated areas
•	Compressor is hermetically sealed, eliminating gas loss from compressor seals
•	Reduced downtime and elimination of seal leakage mitigates methane, VOC, and HAP
emissions as compared to other compressor types.
Exhibit 3 shows the typical operating characteristics for single stage scroll, rotary vane, and
rotary screw vapor recovery compressors.

Different compressor types present different limitations and advantages, allowing an operator to
fill specific niches in vapor recovery operations. Other niche application options include ejector
or eductor vapor recovery processes. Choosing the proper vapor recovery compressor
depends on the required emissions reductions (whether due to permitting or company policy),
availability of power, required discharge pressure, vapor volumes, vapor composition, expected
lifetime of the project, and desired maintenance program. Scroll compressors are successfully
carving their own niche in this important industrial application.
Annual Reporting Season Underway
The Natural Gas STAR 2010 reporting season is underway. With 2009 annual reports due on
April 30th, 2010, Natural Gas STAR Partners should have received annual reporting packets in
the mail, and a STAR Service representative or an EPA Program Manager should have
contacted you to answer any questions regarding the reporting process. Please contact your
STAR Service representative with any reporting questions.
Partners can submit reports in hard copy, email, fax, or electronically through a secure,
password-protected reporting form (refer to box below for submittal options).

Below is a suggested procedure for identifying new projects to report to Natural Gas STAR.
1.	Review operations. Engage in discussions with operators who can identify recent
improvements or current challenges. Other information sources useful for identifying
opportunities include facility emission inventories, copies of process and instrumentation
diagrams, and repair/maintenance logs.
2.	Identify differences between your operations and current PROs. Compare the
technologies and practices used in your operations to the PROs available on the Gas STAR
website. Determine whether certain activities are unique or are improvements on current PROs.
Highlight these findings in your annual report to notify Natural Gas STAR of a new innovative
activity. Partner Reported Opportunities (PROs) are any practice or technology included in
Partner's annual report that reduce methane emissions. In 2008, PROs identified through the
annual reporting process reduced methane emissions by approximately 113 billion cubic feet
(Bcf) which equates to almost $800 million in added revenue when valuing gas at $7 per
thousand cubic feet. As their name suggests, PROs have all been used, reported and identified
by Natural Gas STAR Partners making them tried and tested activities. PROs are a valuable
resource to Partners who wish to expand their emission reduction activities. As a result,
continuously evaluating operations for new project ideas to report is vital.
3.	Report emission reduction activities for 2010. Review current PROs and report to Natural
Gas STAR all existing voluntary methane emissions reduction activities. A complete listing of all
reported PROs can be found on the Program's Web site at
epa.gov/gasstar/tools/recommended.html.
Prospective Projects Spotligh
[ Ideal Transmission Facility
One new approach to identifying and implementing methane emissions reduction projects is to
compare a facility against a conceptual ideal Natural Gas STAR facility. For a compressor
station, the ideal low methane emitting facility assembles the many existing Natural Gas STAR
project types into a comprehensive approach to capture and generate value from all methane
emissions sources.
Since the inception of the Natural Gas STAR Program, transmission Partners have reported
many voluntary cost-effective technologies and techniques to reduce methane emissions, with
projects applicable to virtually every aspect of a compressor station. Typically, transmission
facilities implement these technologies as individual projects. Combining these projects into a
single effort to reduce emissions makes sense as a strategy for operators that are considering
major facility overhauls, new construction, or efficiency improvements. Considering all
applicable types of methane emissions reduction projects can provide an up-front focus on the
value of reduced methane emissions and incorporate it into facility design.
iPartner Update
Spring 2010

-------
The ideal facility approach also treats methane capture-and-use projects as a facility-wide
investment which can financially compete with other projects. The approach is implemented
below using a model transmission system. The ideal facility approach is to define the process
flow, identify paths to the atmosphere, consider mitigation projects for each source, and
evaluate financial performance of the projects.
Background: Gas Transmission Station Methane Emissions
Below in Exhibit 1 is a process flow diagram for a natural gas transmission compressor station.
Compressor stations pressurize pipeline quality natural gas for transport to distribution
networks. Transmission stations typically consist of scrubbers to knock out liquids, reciprocating
compressors and/or centrifugal compressors, and air coolers to reduce gas temperature after
compression.
This process flow depiction of methane emissions identifies key paths to the atmosphere and
the affected parts of the system. Diagramming transmission compressor stations allows all
identified emissions sources to be paired with cost-effective project options.

Emission Reduction Opportunities: Achieving the Ideal Natural Gas STAR Facility
Below is a list of key Partner-reported projects that can form the basis of an ideal Natural Gas
STAR transmission facility.
Directed Inspection and Maintenance (DI&M) has proven to be a cost-effective way to detect,
measure, prioritize, and repair equipment leaks to reduce methane
emissions. A DI&M program begins with a baseline survey to identify and
quantify leaks. Repairs that are cost-effective are then made to the
leaking components. Subsequent surveys are based on data from
previous surveys, allowing operators to concentrate on the components
that are most likely to leak and are profitable to repair.
Using Pipeline Pump-Down Techniques to Lower Gas Line Pressure Before Maintenance
reduces pipeline blowdown emissions by pumping pipeline gas, which would otherwise be
vented for maintenance, further down the pipeline. The cost of running station compressors
and/or employing portable compressors is offset by saving the large amount of gas typically
vented from pipelines undergoing maintenance.
Replacing Wet Seals with Dry Seals in Centrifugal Compressors greatly reduces the most
significant methane emissions source from centrifugal compressors. Alternative projects to
address the same emission source include routing seal oil degassing emissions to low pressure
systems such as fuel gas.
Reducing Methane Emissions From Compressor Rod Packing has economically reduced
methane emissions for many Natural Gas STAR Partners. Gas value lost
from worn rod packing can justify its screening, emissions measurement,
and replacement at economic intervals.
Reducing Emission When Taking Compressors Off-line can essentially eliminate emissions
from compressor blowdowns. Instead of releasing compressor case gas to the atmosphere
during standbys or shutdowns, Partners have kept compressors pressurized when possible.
Blowdown gas can also be routed to fuel gas systems to minimize or eliminate product loss to
the atmosphere.
Management practices and design aspects to monitor and reduce methane emissions
such as developing greenhouse gas inventories to track methane emissions, encouraging all
levels of personnel to develop new project ideas, monitoring ongoing projects, and viewing such
projects as business opportunities can help create a corporate culture to further optimize
operations and maximize environmental performance. Ideal compressor stations can also
incorporate design features to promote regular methane emissions monitoring and control. For
example, one existing Natural Gas STAR project is to locate unit valves to minimize blowdown
volumes. Other design features include incorporating easily accessible compressor vent stacks
so that a minimal amount of staff time is involved when monitoring valve leak or seal vent rates.
Some examples of convenient accessibility include:
•	a flat rather than slanted roof,
•	dedicated, rather than manifolded, vent stacks for major vent sources for easy
identification of leaking components, and
v. A. * Partner Update	8
Spring 2010

-------
• for pipelines, locating connection points for portable compressors to facilitate
pumpdowns.
A key driver of the financial performance of the ideal facility project concept is valuation of
avoided methane emissions. Investigating the potential methods of gas value has been
particularly important in transmission projects where gas custody may be transferred but gas
ownership is not. Financially attractive projects have resulted when valuing the gas in several
ways, including
•	at market price,
•	as fuel gas value,
•	as a means to reduce the lost and unaccounted for volume in a specific transmission
system,
•	as a means to demonstrate a company's commitment to the environment, and
•	as a carbon value.
Many other project types are available when considering facility-wide methane emissions
reductions. Other Partner reported emissions reduction technologies include automated air/fuel
ratio controls, using Yale® closures for emergency shutdown testing, automate systems
operation to reduce venting, converting high-bleed pneumatic devices to low-bleed pneumatic
devices, and convert engine starting to nitrogen.
Transmission station owners typically own the transmission pipelines as well. Pipeline leaks and
blowdowns account for a significant portion of transmission sector emissions. Partner reported
opportunities for reducing transmission pipeline emissions include using composite wrap repair
for non-leaking pipeline defects, using pipeline pump-down technigues to lower gas line
pressure before maintenance, using hot taps for in-service pipeline connections, using inert
gases and pigs to perform pipeline purges, and inspecting flowlines annually.
Implementation and Economics: Ideal Compressor Station Example
Exhibit 2 illustrates potential emissions reductions from implementing the combined projects
shown in Exhibit 1. The total methane emission from the transmission station before project
implementation is estimated to be 78,350 Mcf/year. The potential emissions savings from those
projects shown in Exhibit 2 is $50,817 Mcf per year, resulting in gas savings of $355,717 at a
gas value $7 per Mcf.

The investment to cover project implementation illustrated by Exhibit 2 includes the capital cost
of the DI&M leak detection and measurement equipment, centrifugal compressor dry seal
retrofit cost, new reciprocating rod packing and installation, and the portable compressor for
pipeline pump downs cost. The total capital cost required for a compressor station with
centrifugal and reciprocating compressors is $386,094 or $7.60 per Mcf gas saved in the first
year. Annual operating and maintenance costs include labor costs for conducting surveys and
repairs and leasing a portable compressor are estimated to be $57,525 per year or $0.35 per
Mcf gas saved per year. Positive cash flow in the form of reduced emissions and increased
throughput depend on gas valuation. The example project economics discussed above are
shown in Exhibits 3 and 4. Exhibit 3 represents all projects discussed in the article. Exhibit 4
represents an analysis without the centrifugal compressor dry seal project since it requires
significant capital investment. This presentation allows the other projects to be examined
independent of the more costly dry seal replacement project.

Conclusion
The ideal transmission facility concept illustrates a strategy offering potential positive cash flow
along with climate and air quality benefits. Coordinated implementations of multiple projects
may improve system-wide efficiencies via replicating implementation successes at other
locations and/or identifying additional methane emissions reduction projects.

Deadline Extended to July 29, 2010 for Methane Projects Funding
Continuing its commitment to support projects that reduce methane emissions, the U.S. EPA
announced a new round of grant funding for Methane to Markets projects for 2010. To enable
time for additional submission from applicants, the EPA has extended the deadline to 1 p.m.
eastern daylight time on July 29, 2010.
Since the conception of the Methane to Markets Partnership, the EPA has awarded $13 million
in grants to fund over 70 projects. In 2009, $3.9 million was granted to fund emission reduction
projects. This year, up to 35 projects are anticipated to receive grants ranging from $100,000 to
$750,000, with an estimated total award of $5 million.
Successful proposals will support the Partnership's goals of reducing methane emissions and
advancing project development in the following Methane to Markets Partner countries:
