Rate increases for 1.2 million Wash. natural gas users

OLYMPIA, Wash. (AP) - The cost of natural gas is going up for 1.2 million customers of four utilities in Washington.

The state Utilities and Transportation Commission says it approved the rate adjustments because of rising wholesale prices.

The increases take effect Friday for customers of Kennewick-based Cascade Natural Gas, Puget Sound Energy, Avista in Eastern Washington, and customers in southwest Washington of Portland based Northwest Natural Gas.

About half of Washington's natural gas comes from Alberta and British Columbia and the rest from Rocky Mountain states.
