San Juan Islands/North Puget Sound GRP (SJI/NPI-GRP)

The San Juan Islands/ North Puget Sound is bounded by Point Roberts to the north; the southern tip of Lopez Island and Fidalgo Island to the south; Haro Strait to the west; and the mainland of northern Washington to the east (including Boundary Bay, Semiahmoo Bay, Drayton Harbor, Birch Bay, Lummi Bay, Bellingham Bay, Padilla Bay, Burrows Bay).

The marine and estuarine waters within the San Juan Islands and North Puget Sound are among the most biologically rich and sensitive areas of the State. A wide diversity of shoreline and marine habitats (estuaries, rocks, reefs, and islands), abundant food resources, and exceptional water quality all contribute to making this area especially valuable to wildlife.

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.
