    Special Projects Branch hits 10-year milestone

    In many organizations, there are some tasks and projects that just don’t seem to fit into an easily defined category. This was also the case for the Corps of Engineers Omaha District in 2009. The District had projects that needed to be completed, but didn’t quite fit the mold of the programs they were assigned to. The solution to that issue to the stand up the Special Projects Branch. It was a new concept when the first eight-person team was assembled to take on these outliers, which totaled more than $140 million that first year. Since then, the branch has grown to 52 people and nearly $600 million worth of work annually.

    Optimized Remediation of Groundwater Contamination at the Former Nebraska Ordnance Plant

    The Former Nebraska Ordnance Plant, located in rural Nebraska near the town of Mead, was a 17,250-acre load, assemble and pack facility that produced bombs, boosters and shells in support of World War II and the Korean Conflict. The facility included munition load lines and an Atlas Missile Area, added in 1959.  There are currently four groundwater plumes, each up to four miles long. The primary contaminants within the groundwater are trichloroethene (TCE), a common solvent, and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), an explosive. Despite the existing contamination, the former NOP property is used today for residential, agricultural, and research purposes by the University of Nebraska-Lincoln. The U.S. Army Reserve and Nebraska Air National Guard also own portions of the property.

    U.S. Army Corps of Engineers at Smithville Lake celebrates 30th managed deer hunt

    Nearly 150 people filled a maintenance facility with excitement at Smithville Lake around 4 a.m. Saturday, Nov. 23, 2019. They were all there for one reason, to get out into the wild and seek a big buck this weekend. For the 30th year, the U.S. Army Corps of Engineers at Smithville Lake hosted what’s known as the world’s largest managed deer hunt for mobility-impaired hunters. During this two-day event, 60 hunting blinds are set up across 3,800 acres of prime ground, not available for public hunting. Along with a volunteer, these hunters seek out the best spot near daybreak and wait out their target.
  • CRSO: Introducing the affected environment

    Essential to the National Environmental Policy Act process and the comparison of the alternatives under consideration is the development of the Affected Environment and Environmental Consequences sections of the environmental impact statement.
  • CRSO: Operating dams to support fish passage

    The Corps and Reclamation operate Hungry Horse, Libby, Albeni Falls, Grand Coulee and Dworshak dams to store water to reduce flood damages downstream and deliver water for irrigation, among other purposes. However, storing water can interrupt the seasonal river flow patterns.
  • Defining the Environment under NEPA

    The National Environmental Policy Act requires federal agencies to evaluate each of the alternatives thoroughly to support comparisons about their implementation and their impacts on resources in natural and physical environments.
