6      Natural Gas STAR Partner Update      ★ Fall 2007
      Don’t forget! Register today for the 14th Annual

       Natural Gas STAR Implementation Workshop!

The Implementation Workshop will take place October 22–24, 2007, at
              the Hyatt Regency in Houston, Texas.

This year’s workshop comes at a time of heightened interest in greenhouse gas reductions, and is a forum for
sharing solutions and optimal ways to reduce methane emissions. The workshop will include partner company
presentations on new experiences with reducing methane emissions. Expert speakers will focus on a range of
issues including:

•	   New methods to capture methane emissions
•	   Mitigation projects with positive economics
•	   Technology demonstrations
•	   Environmental, policy, and market issues faced by partner companies
This year’s workshop will also include a free field trip on Wednesday, October 24 to Kinder Morgan Midcon
Texas Pipeline Corporation's Sugarland Compression Station.
More than 140 participants gathered at last year's workshop to network, share information and celebrate the
achievements of this important voluntary partnership, and we expect at least that level of participation again
this year!

     Registration and information on the workshop facility, hotel,
       and sponsorship opportunities are now available on the
      Natural Gas STAR Web site at:
•	   Workshop location: Hyatt Regency in downtown Houston.
•	   Hotel reservations: Call the Hyatt at (713) 654-1234 and reference the EPA Natural Gas STAR Workshop to
     receive the special conference rate by September 24, 2007.
•	   Sponsorship information: Available online, or contact Erin Pittorino, ERG (

If you have any questions please contact Suzie Waltzer, EPA ( or Erin Pittorino, ERG


We look forward to seeing you in Houston!
