We are working to upgrade our natural gas system in Chehalis to our customers' current and future needs. We replaced approximately 6,000 feet of 4-inch natural gas line with 8-inch natural gas line along Coal Creek Road. The 1.2 miles of 8-inch natural gas line run along N. National Avenue and NE Coal Creek Road in Chehalis.

The natural gas system in east King County is reaching capacity. The new line was needed to increase natural gas system's reliability as well as accommodate continued growth in east King County and surrounding areas. PSE's natural gas system works as a large network; any main line upgrade helps stabilize the system in adjacent communities as well as the entire geographic area.

How does natural gas get to my home or business?

Natural gas is a fossil fuel composed almost entirely of methane. Interstate pipelines transport natural gas to regional utility natural gas systems, where it is metered and delivered through a network of local mains, service lines and, ultimately, to customer homes and businesses. More than one-third of all Washington state households and businesses use natural gas.
