authorize the assumption of certain responsibilities and the waiver of sovereign immunity in connection with certain actions under federal environmental law.

SB 71 allows South Dakota's Department of Transportation to take over federal environmental review responsibilities for highway projects under the National Environmental Policy Act (NEPA). It directly affects the state DOT and any parties involved in lawsuits related to these highway projects. Key provisions include waiving South Dakota's sovereign immunity (meaning the state can be sued in federal court) for compliance disputes and requiring the state to pay damages and attorney fees from highway funds if it loses such cases. The bill streamlines environmental reviews for state highway projects but does not change federal environmental standards.
