AltEn Community Update

The below information has been provided in an effort to help keep the community informed on a more frequent basis about progress at the AltEn site. 

Ever since AltEn ceased operations at its facility in Mead in 2021, the AltEn Facility Response Group (FRG) has been voluntarily working under the guidance of the Nebraska Department of Environment and Energy (NDEE) to stabilize the AltEn site and develop a Remedial Action Plan (RAP) for the site. The FRG’s top priorities have been and continue to be to help ensure the safety of the surrounding community and environment. To-date, there has been no evidence of impacts to local drinking water.

The FRG is working diligently with the NDEE to identify the most effective and safest methods to address the current environmental conditions on the AltEn site. The remedial action plans (RAP) will recommend remediation for components remaining on-site, including wastewater, sludge, and wet cake.

Wet Cake Pilot Project

The FRG has resumed the pilot project, which was paused over the winter due to colder weather, with wet cake solidification beginning in preparation for transportation and disposal. Wet cake removal is expected to last five to six weeks.

Northeast Lagoon Liner Removal

Northeast Lagoon liner removal is expected to be completed in July. Remaining lagoon solids are being consolidated, with water being pumped into the Southeast Lagoon for treatment.

Southeast Lagoon Dredging

Starting in July, remaining solids will be removed from the Southeast Lagoon. Dredged solids will be pumped via Geotubes into the Northeast Lagoon after its liner is removed. This work is expected to be completed in September.

Lagoon Water Treatment and Land Application

Water continues to be treated at an on-site treatment facility. As of June 11, around 90 million gallons have been treated; an estimated 25 to 30 million gallons remains to be treated, excluding stormwater. Approximately 60.9 million gallons have been applied to land through Spring 2024. Land application will continue through 2025 until all treated water is applied.

Other Site Activities

A new, larger on-site tornado shelter is being constructed, with completion expected later this summer.
