Sierra Club is appealing the permitting process for a confined hog and cattle operation in Clay County.
A First Circuit judge found that the Club did not have standing to appeal the county's permit.
Sierra Club took that decision to the South Dakota Supreme Court, which heard arguments on Wednesday, Oct. 7.
This is the last of the three-day October session held at the University of South Dakota School of Law.
Victoria Wicks covers this argument for SDPB.
