In March 2017, the Cheyenne River Sioux Tribe (CRST) requested that the EPA Region 8 Emergency Response Program (ERP) conduct a removal action on eight structures. The structures were abandoned, vandalized, burned and on tribally owned land at the CRST Reservation in Eagle Butte, South Dakota.
Previously, in 2014, the Removal Program had conducted a removal action on abandoned structures on tribally owned lands on the reservation where asbestos contaminated material (ACM) was present and posed a threat of release to the environment. The CRST stated that the structures identified in 2017 were of the same age as those addressed during the 2014 removal and were therefore likely to also have ACM present.
On November 13, 2018, an OSC and the EPA Emergency Response and Removal Services (ERRS) contractor mobilized to the reservation and initiated a removal of structures known to contain ACM that represented a threat to human health and the environment.
