US EPA and the Army Corps of Engineers have signed a Final Rule to limit and clarify the scope of the Clean Water Act following the repeal
of the 2015 Waters of the United States (WOTUS) Rule.
At the heart of this Navigable Waters Protection Rule
is a new definition for the key regulatory term “Waters of the United States,” or WOTUS. The definition of WOTUS tells the regulatory community which bodies of water are subject to EPA Clean Water Act programs, including, but not limited to:
- Spill Prevention, Control, and Countermeasure (SPCC) Planning.
- Oil spill notifications.
- NPDES permitting.
- Stormwater discharge.
The Navigable Waters Protection Rule is the result of a two step EPA process.
Step 1 was to repeal the 2015 Waters of the US Rule and reinstate the pre-2015 Clean Water Act applicability standards. Step 2 is the new Final Rule, which sets a new, clearer definition of WOTUS and makes other revisions.
Four Categories of Covered Waters
The new Final Rule lays out four categories of waters that are considered WOTUS:
- Territorial seas and traditional navigable waters;
- Perennial and intermittent tributaries to those waters;
- Certain lakes, ponds, and impoundments; and
- Wetlands adjacent to jurisdictional waters.
The new definition of WOTUS explicitly excludes twelve distinct categories of waters. These include many ditches, groundwater, prior converted cropland, and others. The Final Rule also establishes new definitions for regulatory terms like adjacent wetlands, perennial, ephemeral, ditch, high tide line, and others.
The Final Rule will take effect 60 days after it appears in the Federal Register. Watch this space for an update when the rule is officially promulgated.
A pre-publication copy of the Final Rule is available on EPA's website.
