Georgia and eight other states are suing over new water regulations they say are an overreach by the federal government. The Waters of the United States rule, issued by the Environmental Protection Agency and Army Corps of Engineers, seeks to clarify which smaller waterways fall under federal protection after two Supreme Court rulings had left the reach of the Clean Water Act uncertain. According to the EPA, the waters affected would be only those with a “direct and significant” connection to larger bodies of water downstream that are already protected.
