30 Day Notice

Issue Date: August 16, 2019
Closing Date: September 16, 2019

The U.S. Army Corps of Engineers, Portland District (Corps) is making available for public review the 90% draft Mid-Columbia River Regional Master Plan, integrated Environmental Assessment (EA), and draft finding of no significant impact (FONSI). The master plan is for the Corps’ Mid- Columbia River Projects (Bonneville Lock and Dam, The Dalles Lock and Dam, John Day Lock and Dam, and Willow Creek Project). The integrated EA and draft FONSI were prepared in accordance with the National Environmental Policy Act (NEPA), the Council on Environmental Quality’s NEPA regulations (40 C.F.R. parts 1500- 1508), and the Corps’ NEPA regulations (33 C.F.R. part 230).

The purpose of the Mid-Columbia River Regional Master Plan is to serve as the overall strategic land use management document guiding the Corps’ comprehensive administration and development of recreational, natural, and cultural resources on project lands of the Corps’ Mid-Columbia River Project. The master plan provides an overall land use management plan, resource objectives, and management development concepts for the efficient and cost-effective management, development, and use of project lands for the next twenty years.

Master plans for the Mid-Columbia River Projects date back to the 1970s. A regional master plan is needed to integrate and update management and development planning for the Mid-Columbia River Project in order to guide the responsible stewardship and sustainability of project resources for the benefit of present and future generations. The Mid-Columbia River Regional Master Plan is needed to ensure the management, development, and use of project lands are aligned with national objectives, regional needs, and resource capabilities and suitabilities; protect and sustain project natural and cultural resources; and provide public recreational opportunities that are consistent with authorized project purposes.

The master plan and integrated EA include land classifications, resource objectives and plans and natural resource management recommendations. Resources evaluated include cultural resources, wildlife, aquatic and terrestrial invasive species management, threatened and endangered species, ecological settings, and recreation use and facilities on Project lands within the master plan boundaries. Environmental impacts from a no action alternative and a proposed action alternative (implementation of the master plan) are evaluated in the integrated EA.

Assessment of the Need for an Environmental Impact Statement: USACE has preliminarily determined the proposed action is not likely to result in significant effects on the human environment, and therefore an environmental impact statement (EIS) will not be prepared. The draft FONSI is included with the Master Plan and integrated EA for public review.

Public Comment Period: The master plan, integrated EA, and draft FONSI will be available for public comment for 30-days after the date of this public notice. The public comment period is intended to provide those interested in or affected by this action an opportunity to make their concerns or comments known. The Corps will consider comments received during the 30-day comment period in making a determination on a finding of no significant impact.

The draft master plan and integrated EA are available for download at the following link:
