Governor Inslee of Washington signed legislation to provide funding for Puget Sound Energy to decommission and clean up the Colstrip coal-fired power plant units 1 and 2 in Montana when they retire. The bill establishes a fund to manage the cleanup costs in a way that protects customers and minimizes risks. While the legislation does not mandate retirement, it gives Puget Sound Energy an important tool to facilitate timely retirement of the old and polluting coal units. Environmental groups praised the bill for helping transition Washington to cleaner energy and reducing carbon pollution.
