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.

Mill Creek Supplemental Environmental Impact Statement (SEIS)

Collapse All Expand All
The U.S. Army Corps of Engineers - Walla Walla District (Corps) placed a Notice of Intent in the Federal Register on Feb. 17, 2017, announcing that it intends to prepare a Supplemental Environmental Impact Statement (SEIS), in compliance with the National Environmental Policy Act (NEPA), for the continued operation and maintenance of the federally managed portion of the Mill Creek Flood Control Project at Walla Walla, Washington, and implementation of actions to avoid or minimize potential effects to Endangered Species Act (ESA) -- listed fish and/or associated critical habitat.

The SEIS will supplement the June 1975, Mill Creek Project, Walla Walla, Washington, Final Environmental Impact Statement (FEIS), prepared by the Corps for the operation, maintenance, and improvement of the federally managed portion of the Project. The SEIS will identify and evaluate current O&M actions that may not have been adequately addressed in the 1975 FEIS or have been implemented since completion of the 1975 FEIS, and actions that are proposed for the future. It will also identify and evaluate operational and structural measures the Corps has proposed to improve fish passage through the Mill Creek Project.

The Corps invites affected Federal, state, and local agencies, affected Native American tribes, and other interested organizations and persons to participate in the development of the SEIS. The Corps invites interested parties to provide specific comments on issues and alternatives the Corps should evaluate in the SEIS related to the continued O&M of the Project. Comments, requests to be placed on the SEIS mailing list, and requests for information may be submitted by U.S. Postal Service:

Dworshak Nutrient Supplementation Program / Jan. 27 - Feb. 27

Collapse All Expand All

The U.S. Army Corps of Engineers’ Walla Walla District invites public comments on a Draft Finding of No Significant Impact (FONSI) and Environmental Assessment (EA) for the Corps' proposed “Dworshak Long-Term Nutrient Supplementation Program.” Public comments are being accepted from Friday, Jan. 27, 2017, through Monday, Feb. 27, 2017.

The Draft FONSI and EA documents are available on the Walla Walla District website in the Links section below. The Corps will consider all comments submitted as it performs this environmental review.

The Corps proposes to implement a long-term nutrient supplementation program at the Dworshak Dam and Reservoir Project on the North Fork of the Clearwater River near Ahsahka, Idaho. The purpose of the long-term program is to enhance the biological productivity of Dworshak reservoir, primarily to improve the kokanee fishery and to decrease growth of undesirable blue-green algae, which can be hazardous to human and animal health and competes with desirable plankton for nutrients.

In the EA, the Corps considered five alternatives. These alternatives included changing reservoir operation, mixing reservoir sediments, distributing fish pellets or carcasses around the reservoir, applying liquid fertilizer to the reservoir, or taking no action. The Corps’ proposed alternative is to continue applying liquid fertilizer to add nutrients to the reservoir, as was previously done under two pilot studies.

The Corps started a Dworshak Nutrient Supplementation Pilot Project study in 2007 in conjunction with the Idaho Department of Fish and Game (IDFG) to assess the feasibility of increasing the biological productivity of Dworshak Reservoir and abundance of edible phytoplankton (plant-like plankton) by adding inorganic nitrogen liquid fertilizer. The Corps and IDFG agreed to suspend the pilot study in July 2010, restarted it in 2012, and continued it from spring 2012 to fall 2016. Monitoring data collected during this period indicated the effects of the nutrient supplementation were positive compared with data collected from the reservoir before the addition of the nitrogen. A summary report prepared after the 2015 growing season indicated the amount of edible phytoplankton, zooplankton biomass, primary productivity, and kokanee size increased while the amount of toxin-forming blue-green algae decreased. Drinking water has not been affected by nutrient supplementation.

The North Fork of the Clearwater River is naturally nutrient-poor because of the underlying geology, soils and land use. In the years immediately following Dworshak Dam construction completion in the 1970s, the reservoir initially contained plentiful nutrients from the decomposition of organic material that was inundated by rising reservoir water.  However, the amount of nutrients declined after the initial decomposition. The water in the reservoir eventually returned to a nutrient-poor state.

Comments may be submitted no later than Feb. 27 via e-mail to NEPANWW@usace.army.mil. Insert "Dworshak Nutrient Program" in the subject line. Comments submitted by U.S. Mail must be postmarked no later than Feb. 27 and sent U.S. Army Corps of Engineers, Walla Walla District, CENWW-PPL-C, Dworshak Nutrient Program, 201 North 3rd Avenue, Walla Walla, WA 99362-1876.

Birch Creek Road Bridge Project Section 408

Collapse All Expand All
The Walla Walla District of the U.S. Army Corps of Engineers (Corps) seeks scoping comments from the public regarding the Corps’ proposal to grant permission pursuant to 33 United States Code Section 408 (Section 408) for potential alteration to a Corps-constructed river improvement (public work).

The Corps plans to grant Section 408 permission to the Milton-Freewater Water Control District to allow the modification of the Walla Walla River Flood Control Project (levee system) by the Oregon Department of Transportation (ODOT) to replace the structurally deficient Birch Creek Road Bridge.

The ODOT plans to remove the existing bridge, located on Birch Creek Road and replace it with a new bridge to be located approximately 175 feet upstream (south). The ODOT plans to construct a new bridge upstream of the existing bridge and realign the roadway to provide better approaches. New bridge abutments would be installed on the Corps-constructed levees.

The existing bridge, built in 1956, received a very low sufficiency rating during an inspection completed on July 23, 2014. There is scour along the bridge footings and the bridge is currently limited to vehicles weighing less than three tons. Both ends of the bridge have been damaged by vehicles crossing the centerline to turn onto or off of the bridge because the roadway alignment is substandard.

Public scoping input/comments may be submitted January 18 through Feb. 1, 2017. Comments must be emailed or postmarked no later than Feb. 1, 2017, to be considered in the development of an Environmental Assessment to evaluate the effects of the Corps granting permission to potentially alter the Walla Walla River Flood Control Project (levee system) under Section 408.

Inkom Wastewater System Improvements

Collapse All Expand All

The U.S. Army Corps of Engineers’ Walla Walla District issued a final Finding of No Significant Impact (FONSI) for the City of Inkom, Idaho, Wastewater System Improvements Project. 

The Corps proposed to assist the city of Inkom, Idaho, with its Wastewater System Improvements Project. The purpose of the project is to upgrade the City’s aging and deteriorating wastewater facilities. Improvements would also allow the City to provide wastewater treatment capacity for current and future demands. The proposed action consists of upgrading the existing aerated lagoon treatment facilities, constructing a winter storage pond, constructing a summer sprinkler land application system, and purchasing needed ground for the storage pond and land application areas.

The Corps is not assisting the City with the entire proposed action. The Corps and the City have agreed the Corps would provide funding to assist with effluent disposal, specifically construction of the winter storage pond and the Corps own associated environmental costs. Corps participation in this project is authorized under Section 595 of the Water Resources Development Act of 1999.

The City of Inkom submitted to the Corps an Environmental Information Document (EID) for City of Inkom Wastewater System Improvements. While the Corps had no role in the preparation of the EID, it did undertake an independent review of the document and determined the information contained in it is accurate and satisfies the requirements of the National Environmental Policy Act (NEPA) regulations.

The Corps invited comments about a draft FONSI through Monday, January 30, 2017. Links to the final FONSI, City of Inkom’s EID, and other related documents are available below. For additional questions about the final FONSI, please call the Corps’ Environmental Coordinator at 509-527-7245.

Federal Participation in Watercraft Inspection Stations / Dec. 19 - Jan. 12

Collapse All Expand All
The U.S. Army Corps of Engineers’ Walla Walla District invites public comments on a draft Integrated Letter Report and Programmatic Environmental Assessment (EA) for Federal Participation in Watercraft Inspection Stations in the Columbia River Basin. Public comments are invited beginning Monday, Dec. 19, 2016, through Thursday, Jan. 12, 2017. 

State-managed inspection stations in Idaho, Montana, Oregon and Washington reduce the risk of aquatic invasive species (AIS), such as zebra or quagga mussels carried on watercraft, entering the basin from outside the basin. The Columbia River Basin is one of the last major watersheds in the United States not infested with invasive zebra or quagga mussels.

The Corps proposes to partner with the states of Idaho, Montana, Oregon, and Washington on establishing watercraft inspection stations at locations that provide the greatest likelihood of preventing the spread of aquatic invasive species into Corps-managed reservoirs in the Columbia River basin. In accordance with Section 1039(d) of the Water Resources Reform and Development Act of 2014, the Corps has authority to fund 50 percent of the cost of constructing, operating and maintaining the AIS watercraft inspection stations.

In the Draft Integrated Letter Report and Programmatic EA, the Selected Alternative would augment existing watercraft inspection programs by incorporating a comprehensive range of measures or “suite of tools” to be used and modified annually, depending on each state’s need and ability to fund its portion of the program, the results of regional coordination efforts, and  availability of federal funding. The suite of tools include Corps participation in regional strategy meetings to select the inspection locations, expanding the number of locations or hours of operation, adding canine detection capabilities, improving signage, constructing site improvements, and augmenting existing monitoring efforts and contingency and response planning efforts.

As the Draft Integrated Letter Report and Programmatic EA notes, conservative estimates of average federal and non-federal annual operations and maintenance cost savings associated with deferring an aquatic invasive species infestation for one year is about $250 million. Total estimated costs of the inspection station program within the Columbia River basin is about $3.7 million. Therefore, the benefit-to-cost ratio (BCR) is favorable, about 67 to one. These economic benefits do not include the ecosystem benefits of delaying an infestation.

Mill Creek Levee Extension (Sec 408)

Collapse All Expand All

The Walla Walla District of the U.S. Army Corps of Engineers (Corps) invites public comments regarding the Corps’ proposal to grant permission for alteration to a Corps-constructed river improvement (public work). 

The Corps proposes to grant Section 408 permission, pursuant to 33 United States Code Section 408 (Section 408), to the Walla Walla County Mill Creek Flood Control Zone District for the encroachment of a commercial recreational hall (building) within the easement for the Mill Creek Levee Extension of the Mill Creek Flood Control Project. The levee extension is located between Mill Creek and Titus Creek, about 2 miles east of Walla Walla, Washington. The Corps has determined the structure is not an obstruction to the flow area of Mill Creek and does not affect the hydraulic performance of the levee.

 

Interested parties are invited to provide their comments on the proposed Corps action. The Corps is particularly interested in opinions on issues and environmental effects the Corps should consider when evaluating the County’s request for Section 408 permission for the levee easement encroachment.

City of Vale Waterline Installation (Sec 408)

Collapse All Expand All

 

The Walla Walla District of the U.S. Army Corps of Engineers (Corps) issued a final Finding of No Significant Impact (FONSI) to grant Section 408 permission for a waterline project on the Malheur River in the City of Vale, Oregon. 

The City of Vale plans to replace an existing 8-inch water transmission line that crosses the Malheur River with a new 14-inch water transmission line. The transmission line installation is part of the City’s water-distribution system improvement project to increase pressure, and enhance water flow and circulation capabilities. 

The new transmission line would be approximately 1,300 feet long and would be installed by way of horizontal directional drilling under the Malheur River to connect the new pipeline to the existing distribution system between May 15, 2017, and Oct. 31, 2018. Because the drilling and waterline placement would take place under levee structures constructed by the Corps, these actions require Section 408 permission from the Corps.

The Corps solicited public comments on its draft FONSI June 24-July 24, 2016.
