The Environmental Protection Agency is set Thursday to announce the repeal of the Obama-era Waters of the United States rule that extended federal authority and protections to streams and wetlands, according to a source familiar with the details of the announcement.The announcement is scheduled to take place at the National Association of Manufacturers, a trade group in Washington, DC.The 2015 regulation, commonly known as WOTUS, defined what bodies of water are protected under the federal Clean Water Act but was a favorite punching bag of Republicans, who ridicule it as government overreach. Democrats defended it as necessary to ensure waterways remained pollution-free.Thursday's repeal of the regulation is likely to draw intense litigation from the environmental community.

EPA and the Army Corps of Engineers did not immediately respond to CNN's request for comment.President Donald Trump has repeatedly called clean water a priority for his administration. "We want crystal clean water and that's what we're doing and that's what we're working on so hard," he said in an environmental speech earlier this summer.But the Obama-era rule has been under attack from Trump and conservatives for years.Several states challenged the Obama-era rule, and a federal judge in Georgia 1966
