Sumas Geographic Response Plan (SUMR-GRP)

The Sumas GRP planning area is approximately 53 square miles, and resides within the boundaries of Whatcom County. Fully or partially, it includes the towns or cities of Everson, Nooksack, and Sumas. It entirely resides within the boundaries of the 42nd Legislative District. Portions of WRIA 1 (Nooksack) fall within this planning area, and includes: Bone Creek (3 Miles), Breckenridge Creek (6.3 Miles), Collins Creek (2.3 Miles), Dale Creek (1.4 Miles), Johnson Creek (11.2 Miles), Kinney Creek (2.4 Miles), Saar Creek (5 Miles), Squaw Creek (3.6 Miles), Sumas River (18.6 Miles), and Swift Creek (4.1 Miles). The Nooksack Tribe has reservation lands in the area, and the Lummi, Muckleshoot, Nooksack, Samish, Sauk-Suiattle, Stillaguamish, Suquamish, Swinomish, Tulalip, and Upper Skagit Tribes all have potential interests in the area. Major roadways include: Hwy 9 (15.4 Miles), Hwy 544 (1.5 Miles), Hwy 546 (5.5 Miles), and Hwy 547 (6.9 Miles). BNSF (21.4 Miles) is the only company that owns railroad track in this area.

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.

There are no interim updates at this time
