Waters of the United States
Under the Obama administration, the Environmental Protection Agency (“EPA”) and the Army Corps of Engineers promulgated the Waters of the United States rule, which defined “Waters of the United States” to include small bodies of water, such as rivers and wetlands. However, in early 2018, the Trump administration suspended the rule to re-assess the definition. By the end of 2018, the EPA and the United States Department of Army released a new definition of “Waters of the United States,” restricting the definition to traditional navigable waters and their tributaries, certain ditches, certain lakes and ponds, impoundments and wetlands that are adjacent to water specifically covered by the rule.
The Obama administration’s “Clean Water Rule” was designed to control pollution in approximately 60% of the country’s bodies of water. The Rule primarily extended current federal regulations to smaller bodies of water, requiring that pollution of rivers and wetlands be held to the same environmental penalties as larger bodies of water. However, the Trump administration has suspended enforcement of the regulation for two years. During that time, they will re-consider the definition of “waters of the United States.” The Trump administration intends to release a new version this year.
