On the interstate pipeline grid, the long-distance, wide-diameter (20-42 inch), high capacity trunklines carry most of the natural gas that is transported on the national network.

The 30 largest companies own about 77 percent of all interstate natural gas pipeline mileage and about 83 percent of the total capacity (148 billion cubic feet) available within the interstate natural gas pipeline network. Some of the largest levels of pipeline capacity exist on those natural gas pipeline systems that link the natural gas production areas of the U.S. Southwest with the other regions of the country. Sixteen of the thirty largest U.S. natural gas pipeline systems originate in the Southwest Region, with four additional ones depending heavily upon supplies from the region. Today, almost every major metropolitan area in the United States is supplied by, or is the final destination of, one or more of the major interstate pipeline companies or their affiliates. For instance, New York City is a major delivery point on several
