Lower Columbia River Geographic Response Plan (GRP)
The Washington Department of Ecology is updating the Lower Columbia River Geographic Response Plan (GRP). An important part of the update process is hearing from the people who live, work, and play in the GRP area. To facilitate this, a public comment period will be open from 7/16/2024 – 8/16/2024 at 5pm.
Description of the Planning Area
The Lower Columbia River Geographic Response Plan (LCR-GRP) starts at river mile one and ends at the base of the U.S. Army Corps of Engineers (USACE) Bonneville Lock and Dam located at river mile 145.4. The four-GRP Middle Columbia River region begins on the upriver side of the Bonneville Dam. The borders of each adhere to the specific pool or reservoir created by the four USACE dams (Bonneville, The Dalles, John Day, and McNary). Also included within the plan is the lower Willamette River, which is a 26-mile reach from the Willamette Falls at West Linn/Oregon City, Oregon to the confluence with the Columbia at Kelley Point Park in the City of Portland.
What are Geographic Response Plans?
Geographic Response Plans (GRPs) are used to guide early response actions in the event of an oil spill. Ecology develops and updates GRPs in collaboration with state, local and federal agencies and tribes. 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.
