As in prior years, PROs were a key
contributor to the program's emissions
reduction accomplishments in 2000.
Nearly 70 of these technologies and
practices have been identified and
implemented by Natural Gas STAR
partners. PROs were responsible for
84 percent of production sector
reductions and 44 percent of trans-
mission and distribution sector
reductions.

Program Accomplishments
New Program Tools
Helping partners achieve future emissions reductions continues to be a key focus of the Gas STAR Program. Ten new PROs
have been added to the list of reduction opportunities available as PRO fact sheets. These 10 will appear soon in PDF and
HTML formats on the Gas STAR Web site. Additionally, the format of the fact sheets has been enhanced. Three new Lessons
Learned studies will also be added to the Web site, featuring analyses of desiccant dehydration, directed inspection and
maintenance at gas plants and booster stations, and composite sleeve repair. Six partner case studies that feature successful
program implementation are also available on the Web. Additionally, new online tools under development will help Natural
Gas STAR partners better evaluate, organize, track, and record data for emissions reduction activities.

GTI Study Results Being Published
Directed inspection and maintenance at gas processing plants is among several BMPs and PROs recommended by the Gas
STAR Program for reducing methane emissions. The Gas Technology Institute (GTI), in cooperation with EPA's Natural Gas
STAR Program and industry participants, conducted a leak detection and repair study at four gas processing facilities in late
2000. The objective of the study was to demonstrate with field data that a comprehensive leak detection and repair program
could reduce gas losses while enhancing profits. The selected facilities offered significant opportunities for cost-effective
reductions of natural gas losses. Results indicate that up to 80 percent of plant methane emissions may be eliminated cost-
effectively. For more information on the study results, see the Summer 2001 Natural Gas STAR Partner Update.

The final paper on this study is being published by GTI. For more information, contact Jeff Panek at 847-768-0884 or via

FtKSHO P
With generous co-sponsorship from the American
Gas Association, Indaco Air Quality Services, and
Sealweld Corporation, EPA held the 8th Annual
Natural Gas STAR Workshop in Houston, Texas, in
October 2001. More than 60 participants gathered
to:
• Discuss emerging technologies and practices
• Note the accomplishments of the STAR Program
and program partners
• Learn what other companies are doing to
profitably reduce emissions
• Present new program tools and documents

The workshop focused on how partners have
maximized gas savings and efficiency gains, and intro-
duced partners to the new tools developed over the
past year. These include implementation tools such
as Lessons Learned studies and PRO Fact Sheets, as
well as new Web-based tools for BMP and PRO
analysis, data collection and management, and elec-
tronic reporting.

Keynote Speakers
Highlights from the workshop included two keynote
presentations. Arthur Smith, Senior Vice President
and Environmental Counsel for NiSource, Inc.,
described environmental initiatives being pursued by
NiSource. He emphasized that all eligible NiSource
business units are participating in Natural Gas STAR,
and they have collectively achieved methane emis-
sions reductions of over 11 Bcf. Carl Edlund, Division
Director of the Multimedia Planning and Permitting
Division of EPA Region 6, shared information on
efforts in Texas to reduce ozone and other air pollu-
tants. He discussed Houston's 5-year plan to reach
target emissions reductions by 2007, using enforce-
able commitments such as the Texas Emissions
Reduction Plan (TERP).
Awards for Excellence
As always, the awards ceremony was a high point of
the annual workshop. Partner of the Year Awards
were presented to four companies that have shown
superior performance in the Natural Gas STAR
Program in the areas of emissions reductions, support
of program initiatives and activities, and involvement

Technology Transfer through Industry
Experience
Jeff Panek of the Gas Technology Institute
described results from a study of cost-effective
directed inspection and maintenance practices at
gas processing plants. The workshop also includ-
ed presentations from partner companies BR
Dynegy Midstream Services, and Phillips
Petroleum on methane reduction projects and
tips for successful program implementation. The
three presentations are summarized below.

Partner Presentations
Phillips Petroleum Company. Robert Wirtanen
presented an overview of the Natural
Gas STAR Program at Phillips
Petroleum Company, which became a
Gas STAR partner in 1999. Highlighting
the implementation plan for Phillips from 2001
to 2003, Mr. Wirtanen discussed the seven man-
agement practices that Phillips implemented in
2000. These included installing low-bleed con-
trols and actuators, removing dehydrators from
service, reviewing condensate storage tanks for
vapor recovery, performing directed inspection
and maintenance, and installing plunger lifts and
pumping units. He also discussed the emissions
reduction activities implemented at the San Juan
Basin, which included compressor starters,
plunger lifts, screw compressors, shutting-in
dehydrators, and pump-jacks on coal-bed
methane wells. Phillips 2000 reductions totaled
98,000 Mcf.

Dynegy Midstream Services, LP.
Ananthakrishna Shankar presented Dynegy's
experiences with the Natural Gas STAR Program.
He first discussed Dynegy's
participation in GTI's gas plant
study for which Dynegy con-
tributed two host testing facilities. The study
results helped direct Dynegy's implementation of
Gas STAR. Mr. Shankar recommended gathering
emissions reduction information from monthly
field meetings, requesting information through
DYNEGY
e-mail, incorporating the data into an emissions
inventory, and requesting assistance from environ-
mental safety and health advisors. Mr. Shankar
highlighted plans to conduct directed inspection
and maintenance at six upstream compressor sta-
tions. He also mentioned Dynegy's future plans,
which include four Natural Gas STAR training
sessions/meetings in 2002 and increased involve-
ment of management and the media relations
department.

BR Reid Smith gave an overview of the "Green
Completions" program at BR This program aims
to reduce flaring and venting at the
well site, through
steps taken during
drilling and well
completion. Venting and flaring
are prevented by directing initial
flow to specially designed surface
equipment, and by using a sand
separator. The sale of recovered
hydrocarbons then offsets the
equipment costs. Mr. Smith high-
lighted a field pilot in Wyoming's
Green River Basin. In the pilot,
green completion techniques
avoided the release of an estimat-
ed annual 600 Mmcf of natural
gas. The project had an internal
rate of return of 100 percent. Mr.
Smith noted that a key benefit of
implementing green completion
techniques is increased produc-
tion without the expense of
drilling new wells.
"Your voluntary efforts to
reduce methane emissions
while delivering dependable
energy to American homes
show that good stewardship
of the environment can also
mean good business. This
Administration believes
strongly that we can harness
the creativity and innovation
of industry—through
programs such as Natural
Gas STAR—and put it to
work for the environment.
You have shown that this
approach can be very
successful."
Christine Todd Whitman
New Online Program Tools
The Natural Gas STAR team presented three new
Web-based program tools—a BMP/PRO analysis
tool, a data collection and management tool, and
an online reporting tool—all of which will help
facilitate partners' decisions to implement emis-
sions reduction activities and their efforts to track
and record emissions reduction data. Available in
Natural Gas STAR Partner Update • January 2002
-------
2002, the tools will be accessible with a password
via the Natural Gas STAR Web site. Following is a
brief description of each tool:

• The BMP/PRO Analysis Tool will allow
partners to generate estimates of the economic
and environmental benefits of methane
reduction activities on a site-specific basis. The
tool will calculate capital costs and operation
and maintenance (O&M) costs; provide default
values for critical capital and annual cost
factors, methane emissions reduction factors,
and other operating assumptions; and project
cash flows during the first 5 years of operation.
Users will be prompted to enter site-specific
values where available, or use the default
values provided. The tool will be ready for
beta-testing by partners in spring 2002.

• The Data Collection and Management Tool
will streamline data collection and the annual
reporting process. This tool will help partners
collect and manage information about
methane emissions reduction activities
occurring at various locations across their
companies by allowing remote users to record
site-specific data. Users can enter, save, and
view data for all BMP and PRO activities. The
tool performs calculations, generates several
printable reports, including the annual Natural
Gas STAR Report, and allows partners to
export data for expanded use. Implementation
managers will control and approve remote
user access.

• The Online Reporting System is an option
for partners who wish to submit their annual
report via the Natural Gas STAR Web site.
The online forms mirror the hard copy report
forms, allowing partners to enter both current
and historical data for all BMPs and PROs
within their sectors. Unlike the online data
collection tool, a comprehensive data
management tool that stores historical
emissions reduction data, the online reporting
system temporarily stores data for the current
reporting year. The online forms will facilitate
data entry for partners by performing
calculations and providing default values.
Partners can access the forms for the spring
2002 reporting period at www.epa.gov/gasstar.

New Lessons Learned Studies
Participants reviewed and commented on drafts
of three new Lessons Learned studies covering
(1) composite sleeve repair of pipelines;
(2) directed inspection and maintenance at gas
processing plants and booster compressor sta-
tions; and (3) replacing glycol dehydrators with
desiccant dehydration systems. EPA thanks the
many Natural Gas STAR partners who provided
feedback and contributed data and other infor-
mation to the development of these documents.
These 3 new Lessons Learned studies will bring
the total available to 1 7. The new studies will be
posted on the Natural Gas STAR Web site by
mid-2002.

Keeping Up with Emerging
Technologies - the Partner Roundtable
The annual partner roundtable discussion
centered on two presentations. Jeff Panek of
GTI discussed new and emerging leak detection
devices. He queried partners as to their interest
in holding a special hands-on workshop to
learn more about these technologies. EPA is
collaborating with GTI to sponsor such a
workshop this year.

Sushma Masemore of the Southern Research
Institute (SRI) described the Environmental
Technology Verification Program (ETV), a joint
initiative by EPA and SRI. ETV provides
independent, objective performance verification
of commercially ready technologies with strong
environmental benefit, such as technologies
with the potential for greenhouse gas emissions
reductions. Currently, Natural Gas STAR is work-
ing with ETV to sponsor the verification of Comm
Engineering's eductor vapor recovery unit.

Gas STAR Claims Methane Emissions Reductions of 34 bcf in 2000
By the OGJ Online Staff
Houston, Jan. 11 2000 - The US Environmental Protection Agency said industry participants in its Natural Gas STAR
Program reduced methane emissions by 34 Bcf in 2000.
EPA said at $3/Mcf, the savings are worth $102 million. The voluntary STAR program, designed to reduce green-
house gas emissions, has 90 industry participants across all sectors of the gas industry.
EPA said since the program began in 1993, it has reduced methane emissions from field operations and equipment
leaks by 176 Bcf, worth more than $500 million and equivalent to eliminating the emissions from more than 14.2 million
cars or planting 21 million acres of trees.

Southwest Gas & Natural Gas STAR
Saving Gas and Money
(and helping the environment, too)
Since 1997, Southwest Gas has saved an estimated $3.8 million dollars
through participation in EPA's Natural Gas STAR Program, Through this
voluntary partnership, Southwest Gas and nearty 90 other companies -
including 41) LDCa - utu wurkiny li> maximize u|ieralimal efliuinriLy by

Cumulative Reduced Gas Losses -1997-2000
Musi importantly, our lauilitias ntut^ers jnJ anlire atalf Irdw beanne knnrily
aware nl the importance at minimizing gas toss through both liaditranial and

Southwest Gas to increase our company's competitive edge.
In October, 2001, Southwest Gas and
EPA teamed up at the American Gas
Association Operations Conference to
promote the Natural Gas STAR Program
to AGA's membership. EPA developed
the card on the left, which was distrib-
uted by Jim Wunderlin, VP of Operations
at Southwest Gas.
Technology Transfer Workshops Continue To Provide Value to Producers
Over the past year, the Natural Gas STAR Program held four
successful Producer Technology Transfer Workshops in
Hobbs, New Mexico; Denver, Colorado; Gaylord, Michigan;
and New Orleans, Louisiana. These free workshops offer in-
depth information on relevant technologies and a forum to
discuss emerging technologies or issues of regional impor-
tance. To ensure regional applicability, technical presenta-
tions are selected based on input from local operators.
Topics to choose from include improving dehydrator effi-
ciency, installing vapor recovery units, using plunger lifts in
gas wells, replacing high-bleed pneumatics, and reducing
compressor emissions. A new interactive component allows
participants to walk through a cost-benefit analysis for a
selected project, using company-specific information.

In 2002, Gas STAR will again hold producer workshops;
sites being considered include Wyoming, Texas, and
Louisiana. In addition, EPA plans to expand the program
in 2002 to offer a technology transfer workshop for gas
processors. All of the workshops are free and open to both
current and prospective partners.
Please visit the Natural Gas STAR Web site, or call your STAR
Service Representative for more information on upcoming
workshops. If you are interested in co-hosting a workshop in
your area, please contact the Natural Gas STAR Program
manager at (202) 564-2318.

The Natural Gas STAR Program would like to thank the
organizations and partner companies that helped make the
four technology transfer workshops held in 2001 a success.
