The legislaure of the Hopi Tribe in Arizona rescinded their approval of a project to determine whether tribal land is suitable for carbon storage.
The Tribal Council narrowly rejected the federally funded project last week that it had earlier approved in July. The reservation was one of two areas in Arizona identified by researchers for such testing.
Tribal lawmakers raised concern about potential environmental damage, groundwater contamination and risks to public safety rescinding approval. Proponents said the drilling would have allowed Hopis to make an informed decision about whether to allow carbon storage on the reservation if the geology was right. The project called for drilling a 7,000-foot well beneath the Black Mesa Basin.
