What are 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.
