The Environmental Protection Agency's new definition of the Waters of the United States (WOTUS) greatly expands the number of projects that would have to go through regulatory review--in some cases, roadside ditches could be considered WOTUS. Industry groups like the Portland Cement Association and the National Association of Home Builders are fighting this and have joined in a law suit challenging the new rules.

“Through WOTUS, federal regulators are asserting unprecedented regulatory authority over large and small bodies of water throughout the US, exceeding the scope that was set by Congress and upheld by the Supreme Court," said PCA president James Toscas.  "This will create needless gridlock, delays, and cost for construction projects across the country, with little or no benefit to the environment.”

A coalition that includes the U.S. Chamber of Commerce and the National Federation of Independent Businesses (NFIB) has filed a legal challenge.
