Spills Program

Geographic Response Plans

Geographic Response Plans (GRPs) are plans that guide oil spill response in Washington, Oregon, and Idaho. Each GRP is written for a specific area (for example a river, a lake, or section of Puget Sound), and includes tactical response strategies tailored to a particular shore or waterway at risk of injury from oil. GRPs have two main objectives:

  • Identify sensitive natural, cultural or significant economic resources at risk of injury from oil spills.
  • Describe and prioritize response strategies in an effort to reduce injury to sensitive natural, cultural, and certain economic resources at risk from oil spills.

Ecology partners with Oregon Department of Environmental Quality (OR-DEQ), the U.S. Coast Guard (USCG), and the U.S. Environmental Protection Agency (US-EPA) for GRP development. 27 GRPs are complete while five are being updated and four being developed in the 2015-2016 cycle.
