Washington, D.C. — 

U.S. Senator John Thune (R-South Dakota) today launched a new interactive map on his website displaying South Dakota rivers, streams, wetlands, flood plains, and other waterways that could be under new federal regulation due to a proposed power-grab from the Obama administration.

“The Obama EPA’s power-grab over small and seasonal bodies of water could have a devastating economic impact on our state’s farmers, ranchers, homeowners, and businesses,” said Thune. “South Dakotans deserve to know where the EPA will target and with what regulations property owners will be forced to comply. I encourage all South Dakotans to explore the map to help better understand the impact this rule could have on properties throughout the state.”

The map displays analyses from the American Farm Bureau Federation, which compiled data from the U.S. Geological Survey and the Federal Emergency Management Agency for 19 states to map areas the Environmental Protection Agency (EPA) could regulate under the new proposed definition of “waters of the U.S.” Thune has been fighting to stop the EPA’s proposal  from being finalized due to concerns that the rule would provide the EPA and U.S. Army Corps of Engineers authority to begin regulating small and seasonal bodies of water that have typically been regulated at the state level. Thune’s map allows users to locate potentially regulated areas on their property.
