(AP) — The Kansas Department of Health and Environment says an auction is planned for land in a former southeast Kansas town contaminated by mining.

KDHE says in a release the Treece Relocation Assistance project has entered its final phase. The TRA Trust and KDHE worked since 2010 to relocate Treece residents after the town was deemed unsafe because of decades of residual lead and zinc waste. The buyouts were completed last year.

The TRA Trust’s auction is scheduled for Saturday in nearby Picher, Okla., and will involve selling 10 plots of land in the Treece area. Each plot will have restrictions prohibiting the land from being used for human occupancy and building. KDHE says acceptable uses include wildlife habitat and livestock grazing.

Treece was removed from the Kansas map last year.
