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.

There are 41 GRPs for Washington state. Eleven of these are new and open for the public to review and comment on. Twenty-seven are active, and three are draft plans for which the public comment period has already passed.

Draft GRPs open for comment

We value your input and hope you’ll let us know how these plans might be improved.

Public comment period from May 16, 2017 to June 15, 2017

We have 11 GRPs available for your review and comment.

These 11 draft plans will be published at the end of next month along with plans for three other new areas that were completed earlier this year. This will bring the total number of GRPs in Washington to 41. The expansion GRPs in Washington is a result of the 2015 Oil Transportation Safety Act, and highlights our state’s efforts to protect the environment and Washingtonians from new oil spill risks.

Public comment opportunities after June 15, 2017

Other draft GRPs

The formal public comment period for these GRPs has passed, but we do accept comments on any GRP at any time at the above email and mail addresses.

GRPs are living documents that can be revised at any time based on new information from comments and lessons learned from drills and spills. These changes are typically reflected as interim updates until they are fully incorporated into plans during future updates.

Completed GRPs

There are 27 active GRPs for Washington state.
