Interim GRP Updates to Middle Columbia River - Dalles Pool
The Washington Department of Ecology is performing an interim update on the Middle Columbia River - Dalles Pool 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 Wednesday 11/6/2024 – Friday 12/6/2024 at 5:00 PM.
Description of the Planning Area
This section provides a description of the physical features, hydrology, climate, and winds, found along the Middle Columbia River (MCR) corridor and includes an overview of the oil spill risks in the region. The Columbia River travels 1,243 miles, originating in British Columbia, Canada and running through Washington, providing a border between Washington and Oregon before eventually entering the Pacific Ocean. Although the Columbia River originates in Canada, the NOAA river mile system used in these geographic response plans (GRPs) begins at the confluence of the river with the Pacific. 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 Middle Columbia Region begins at river mile 145.4 on the upstream side of the Bonneville Lock and Dam and is subdivided into four separate GRPs, each a specific pool created by one of four USACE dams in the region: Bonneville, The Dalles, John Day, and McNary.
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.
