"In a case that has become a local flashpoint, environmental groups seeking to halt a lithium operation in Imperial County until it gets further review argued before a state appeals court in San Diego on Thursday.
Controlled Thermal Resources wants to extract lithium from hot brine that will be used to power a geothermal electricity plant it plans to build. This type of lithium removal is different from traditional hardrock mining or evaporation ponds. The project also would need 6,500 acre-feet of fresh water annually for washing the mineral and cooling.
Earthworks, a nonprofit focused on the impacts of mining, and Comité Cívico del Valle, an Imperial County environmental justice group, allege the county didn’t adequately examine the project’s effects on water supply, air quality and tribal cultural resources when it granted approvals."
