Vector Pipeline and ANR Pipeline complete interconnection at St. John, Indiana

LIVONIA, Mich., May 20, 2003 — A new interconnect between Vector Pipeline L.P. and ANR Pipeline Company at St. John in Lake County, Indiana, is now in-service and offers natural gas customers in the Midwest and southwestern Ontario additional flexibility and access to natural gas supplies at the Joliet/Chicago Hub. ANR Pipeline is a subsidiary of El Paso Corp.

“Existing and future shippers on the Vector and ANR pipeline systems will benefit from this interconnection,” said Craig R. Fishbeck, Vector President. “This will provide ANR customers access to markets in southwestern Ontario and Vector customers additional supply security with access to Mid-continent, Rockies and Gulf Coast supplies on ANR.”

The St. John facilities, with a design capacity of 200 MMcfd, interconnect two high-pressure natural gas transmission systems that cross the U.S. Midwest.

“This cooperative effort continues to demonstrate ANR Pipeline’s commitment to providing its customers access to new growth markets and enhancing market diversity,” said James J. Cleary, president of ANR Pipeline Company. “Through this interconnection, ANR and Vector will capitalize on their existing infrastructure as well as their access to diverse supply sources to provide cost-effective transportation and storage services to the Midwest and eastern Canada.”

The 42-inch Vector Pipeline transports Western Canadian natural gas from the Chicago-area market hub in Joliet, Illinois, to the hub at Dawn, Ontario, providing access to markets and storage in the upper Midwest and eastern Canada.
