For our South Dakota neighbors

We think it is important to keep our neighbors informed about the construction of the Long-Baseline Neutrino Facility and the Deep Underground Neutrino Experiment. To ensure that you have the most up-to-date information, we have set up this website with information about LBNF and DUNE.

Dust in Lead

We understand the community’s concerns about dust within Lead, emanating from the Open Cut. We apologize for the significant inconvenience and understand the community’s frustration. We are committed to working to resolve this issue as quickly as possible. Please download the commonly asked questions regarding the dust (pdf). We will continue to keep these updated as we receive new questions. If residents have additional concerns, please do not hesitate to contact us at neighbors-sd@fnal.gov.

We encourage our neighbors in Lead, South Dakota to follow us on Twitter (@LBNFacility) or Facebook (Long-Baseline Neutrino Facility). You also may want to subscribe to the free weekly newsletter Deep Thoughts published by Sanford Lab.

Below you will find links to letters sent to residents of Lead, talks that were presented at informational meetings in South Dakota as well as articles and other information about LBNF and DUNE for local residents.

Environmental assessment

With the help of a number of technical experts, including independent consultants assisted by Fermilab and Sanford Lab staff, the U.S. Department of Energy prepared an environmental assessment to determine what impacts LBNF and DUNE construction and operation might have on human health and environment.

Public meetings were held on June 17, 2015, in Lead, South Dakota, June 18, 2015, in Rapid City, South Dakota, and June 24, 2015, in Batavia, Illinois.
