PSE completes $15 million natural gas project in south Tacoma area

BELLEVUE, Wash. (Dec. 15, 2008) – Puget Sound Energy today announced the completion of construction of the new $15 million Frederickson distribution natural gas supply main between PSE’s existing Frederickson gate station and the utility’s new Clover Creek limit station in south Tacoma.

“The Frederickson natural gas project provides another important link in our infrastructure to strengthen PSE’s natural gas system, improve reliability and increase capacity for this growing area of Pierce County,” said Sue McLain, senior vice president of Operations for PSE.

Construction began in August with the work advancing in approximately 200-foot increments each day. Natural gas began flowing through the new line on Dec. 14. Restoration of the project site will continue over the next several weeks.

The project involved installing five and a quarter miles of 16-inch natural gas line and building the new Clover Creek limit station located on 128th St. E. Gate and limit stations are devices in the natural gas distribution system that regulate the pressure of the natural gas, typically decreasing the pressure of the natural gas for use in residences and businesses.
