Central Puget Sound Geographic Response Plan (CPS-GRP)


The existing Central Puget Sound planning area covers 654 square miles, bounded by Kingston and Edmonds to the north, Bremerton to the west, Seattle to the east, and Tacoma to the south. Portions of Water Resource Inventory Areas 6, 8, 9, 10, 12, and 15 are included in the area.

Spill risks include commercial and recreational vessel traffic, including six Washington State Ferry routes across the sound; 244 miles of rail, including 65 miles owned and operated by BNSF; 13 miles of oil pipeline (BP Northwest Pipelines District and U.S. Oil/McChord); and countless miles of highways and roadways.

The area is also populated by more than a handful of regulated oil facilities. The CPS-GRP was last updated in July 2007 but it neither includes detailed 2-page response information sheets in Chapter 4 nor information about oil spill risks in Chapter 2. The anticipated release date of the updated plan is summer 2017.

Interim Updates

In between plan updates, GRP strategies are tested during drills and actual spill events. The results of these tests may require changes to certain response strategies, notification strategies, staging areas, or boat launch locations. Eventually, these changes will be fully incorporated into the plan. Until that time, please use the updated strategy and information sheets below in lieu of that provided for similarly numbered locations in the published plan.

No interim updates currently available
