About Us

Environmental Compliance provides extremely broad support to all of the district’s civil works federal actions and programs in three functional areas: environmental sciences as well as compliance with federal biological compliance laws (Biological Resources Team) and general environmental compliance (Environmental Resources Team) laws. Our two functional teams conduct roughly 400 environmental effect analysis determinations and appropriate documentation annually under the National Environmental Policy Act and the Endangered Species Act, amongst numerous other environmental laws and Executive Orders.

We consult with the state, federal and tribal environmental regulatory and natural resources management agencies on federal actions where there are interests external to the Corps and ensure the Corps meets requirements for consultation.

Lucky Peak Lake View Trail

Collapse All Expand All

The US Army Corps of Engineers has signed the Finding of No Significant Impact (FONSI) for the proposed Lake View Recreation Trail, Lucky Peak Dam Environmental Assessment (EA). The signing of the FONSI concludes the Corps environmental compliance for this action.  Based on the need to balance a broad range of interests, considerations, priorities and values expressed by key stakeholders, the Corps will implement the No Action Alternative at this time. 

The Proposed Action was to build a 15 mile multiple use trail along Lucky Peak Lake’s southern shoreline from Lucky Peak Dam to the Chimney Rock area.  The trail would have allowed increased access to recreational opportunities that include hiking, hunting, biking, wildlife viewing, camping and day use at waterside campgrounds, as well as provided potential fire management.

The Corps distributed the draft FONSI and EA for this action on May 22, 2020 for a 30-day public review. That review time was extended at the request of the Idaho Fish and Game so they could further evaluate the proposed action, for an additional 60 days ending on August 20, 2020.

If you have any questions about the final FONSI, EA or the Corps Responses, please contact Mr. Ben Morris, Environmental Coordinator, at 509-527-7294 or preferably at Benjamin.W.Morris@usace.army.mil

Granite Creek Public Notice

Collapse All Expand All

In compliance with U.S.C. Title 33, Chapter 9, Subchapter 1, Section 408, Snake River Ranch has requested permission to alter the JY Ranch Levee, associated with the Jackson Hole Levee Project, an existing Federal flood risk management project.  The proposed alteration would include removal of three existing, 4-foot steel pipes and associated headgates and wooden retaining wall along approximately 41 linear feet of the levee and installing three, 8 foot wide by 7 foot high box culverts with sliding headgates between RM 979 and RM 980 on the Snake River.  The levee prism within this location would be restored to the as-built condition, except the intake structure would be 4.5 feet below the existing structure elevation to reduce water pressure through the intake structure for improved fish passage. 

The public is invited to comment on the impacts of the proposal on the quality of the human environment for the next 30 days, starting Nov. 20.

Waitsburg Levee Emergency

Collapse All Expand All

Interested parties are hereby notified that the Walla Walla District of the U.S. Army Corps of Engineers (Corps) proposes an activity that is subject to the provisions of Section 404 of the Clean Water Act (CWA) of 1977 (Public Law 95-217).

The Corps proposes to repair a levee (totaling 220 linear feet [lf]) damaged by historic flooding in the spring of 2020 along the Touchet River in Walla Walla County, Washington.  These repairs need to be completed as soon as possible as the upcoming Touchet River flood season starts December 2020.  Therefore, the Corps proposes to perform the repair as soon as possible in November and December of 2020. 

The Corps repair would include the construction of an upriver revetment (140 lf) outside of the pre-flood footprint intended to prevent failure of the downstream levee.  The 140 lf levee revetment would involve work below the ordinary high water mark.  Without the revetment extension, the repaired levee system would continue to be vulnerable to the river flanking the upstream end of the left bank levee system at approximately the 10-year flood recurrence interval.  Implementation of the levee repair and revetment extension is expected to provide 100-year (1% annual chance exceedance) level of protection.

Ice Harbor Master Plan Revision and Environmental Assessment

Collapse All Expand All

The U.S. Army Corps of Engineers, Walla Walla District (Corps), plans to revise the 1977 Ice Harbor Master Plan and prepare an accompanying Environmental Assessment.  The Master Plan guides how the Corps manages Ice Harbor project lands surrounding Lake Sacajawea behind Ice Harbor Dam.  It is a conceptual document that focuses on management and development of the natural, cultural, and recreational resources on the Corps lands for the next 20 years.  It does not address dam operations (e.g., spill, fish passage, or dam breaching), flood risk management (e.g., levees), or navigation.  The Corps is revising the existing 43-year-old Master Plan because Corps land management regulations have changed, and because the existing plan may not meet current or future needs of the public or the project resources. 

As part of the Master Plan process, the Corps is also preparing an Environmental Assessment (EA).  The EA will identify and evaluate the environmental effects of a range of alternatives for future management of Ice Harbor lands, including the No Action Alternative (No Change in Current Management).

The Master Plan revision and EA preparation are now in the scoping phase.  This is the public’s opportunity to tell the Corps how they use the public lands surrounding Lake Sacajawea and how they would like to see the lands managed in the future.  The public can also tell the Corps what alternatives should be considered and what environmental issues or concerns should be addressed in the EA.

The Corps will be accepting scoping comments for the Master Plan revision and EA from May 1 through June 15, 2020.  Information on how to submit comments is provided on the Ice Harbor Master Plan web page.  Comments can be submitted through several means, including a link on the Master Plan web page.  Additional information about Ice Harbor project and the Master Plan update can be found on the Master Plan webpage

Ice Harbor navigation lock upstream floating guidewall cables repair

Ice Harbor Floating Guidewall Cable Repair Update April 20, 2020

The U.S. Army Corps of Engineers’ Walla Walla District (Corps) has temporarily halted its repair of the cable anchoring system used for the Ice Harbor Dam navigation lock upstream gate floating guidewall.  The steel cables have deteriorated and need to be replaced.  The Corps was able to replace the set of cables attached to the shoreline anchor block during the in-water work window that ended in early 2020.  However, because of COVID-19 concerns, the Corps was unable to complete the dredging needed to access the anchor block on the river bottom.  The Corps proposes to complete the dredging within the winter in-water work window of December 15, 2020 through February 28, 2021 and attach the remaining cables.

The Corps issued a Public Notice for this project on December 12, 2019 and the public comment period closed January 13, 2020.  The Corps prepared a Statement of Findings documenting the results of its environmental analysis and its decision to implement the project.  The Statement of Findings was signed February 12, 2020.

Boyer Park Marina Dock Replacement Project

Collapse All Expand All

*****Update: This comment period is now closed*****

The U.S. Army Corps of Engineers’ Walla Walla District (Corps) is seeking input on the Draft Finding of No Significant Impact (FONSI) and Environmental Assessment (EA) for the Boyer Park Dock Replacement Project.

The project proposes to approve a request from the Port of Whitman County to complete a series of improvements on lands leased from the Corps in Boyer Park and Marina, including the repair, realignment, and replacement of docking facilities in the marina, as well as associated upland improvements.

The purpose of the proposed action is to repair and upgrade the existing moorage and facilities in the marina to ensure continued safe recreational boating support services. The proposed action is needed because existing facilities in the marina are deteriorating and pose a risk to marina users as well as the environment. Additionally, marina facilities, including those for potable water and electricity, are approaching the end of their planned lifespan and no longer provide an acceptable level of service.

The comment period was open from Oct. 11 to Nov. 11.   All comments submitted were included in the permanent public record

For additional information, contact Mr. John Hook, Environmental Resource Specialist, at 509-527-7239.

Aquatic Invasive Rapid Response Plan

Collapse All Expand All

*****Comment Period ended August 19. Final FONSI available below************

The U.S. Army Corps of Engineers, Walla Walla District (Corps) is proposing to assist the states with establishing and executing rapid response measures if discovery of dreissenid mussels within the four-state area occurs.  Rapid response actions could also be conducted by the Corps or by other federal land managing agencies at federally owned or managed water resources projects and related facilities (e.g., dams, boat ramps, etc.) within the CRB.  The proposed action is needed because the risk of water bodies in the CRB being infected is high and the introduction and establishment of zebra or quagga mussels has the potential to cause billions of dollars in economic damage and untold damage to the ecosystem and the species dependent upon it.

The Corps solicited comments on a Draft Finding of No Significant Impact (FONSI) and Environmental Assessment (EA) for a Rapid Response Action Plan (Plan) for the eradication of potential zebra (Dresissena polymorhpa) and quagga mussel (D. bugensis), infestations in the Columbia River Basin (CRB), as well as across infested waterbodies in the states of Washington, Oregon, Idaho, and Montana.

 

The 30-day comment period was be from July 19, 2019 to August 19, 2019.  All information and comments submitted were included in the permanent public record and addressed in the final FONSI.

Flowering Rush Control Project

Collapse All Expand All

The U.S. Army Corps of Engineers, Walla Walla District (Corps) released the Draft Finding of No Significant Impact (FONSI) and Environmental Assessment (EA) for flowering rush control in the States of Washington, Idaho, Oregon, and Montana.  Flowering rush is an aquatic invasive plant species, non-native to the Pacific Northwest.

The Corps proposes to share flowering rush control treatment costs with the Pacific States Marine Fish Commission to treat infestations on non-Federal lands.  The goal of treatment is to prevent and/or minimize the impacts of flowering rush invasion on habitat, irrigation, and recreation.  The aim is to eradicate known and future flowering rush populations and provide continued subsequent control at a much-reduced effort.

The Corps’ participation in this project is authorized under Section 1039(d) of the Water Resources Reform and Development Act of 2014 (Public Law 113-121) and Section 1178 of the Water Infrastructure Improvements for the Nation Act of 2016 (Public Law 114-322).

The 30-day comment period was from June 24, 2019 to July 24, 2019 and has since closed.  All information and comments submitted will be included in the permanent public record.
