Gas Pipeline Operations
Williams operates three major interstate natural gas pipelines systems:
- Northwest Pipeline
- Transco
- Gulfstream
About Northwest Pipeline
Williams' Northwest Pipeline system has changed significantly since its beginnings more than 50
years ago. Like the Western states it serves, Northwest's transmission system has expanded to
meet the demands of growth. Today the pipeline is a primary artery for the transmission of
natural gas to the Pacific Northwest and Intermountain Region.
What began as a 1,500-mile pipeline is now a 3,900-mile bi-directional transmission system
crossing the states of Washington, Oregon, Idaho, Wyoming, Utah and Colorado. Northwest's
bi-directional system provides access to British Columbia, Alberta, Rocky Mountain and San Juan
Basin gas supplies.

About Transco
During the past 50 years Williams’ Transco pipeline has been quietly, safely and reliably delivering
natural gas to its customers through its 10,500-mile pipeline system, extending from South Texas to
New York City.
The Transco pipeline system is a major provider of natural gas to the northeastern and southeastern
states. Its compressor stations help move gas from the Gulf Coast to 12 Southeast and Atlantic
Seaboard states, including major metropolitan areas in New York, New Jersey and Pennsylvania.
