“There’s always something going on with the waters of the United States (WOTUS) rule. Last September, we wrote about how the 1986/1988 WOTUS rule would replace the 2015 Obama rule until the Trump administration finalized its new rule. Well, the final rule was just announced by the EPA on January 24, 2020. So, what does the new rule categorize as “waters of the United States?” Are there any differences between the rule as it was proposed in February of 2019 and the final rule? Will this version of WOTUS stick?
What is (and isn’t) WOTUS now?
The Trump EPA’s WOTUS rewrite maps out which waters are and are not waters of the United States. The following are WOTUS in the new rule:
- The territorial seas, and waters which are currently used, or were used in the past, or may be susceptible to use in interstate or foreign commerce, including waters which are subject to the ebb and flow of the tide;
- Lakes and ponds, and impoundments of jurisdictional waters; and
- Adjacent wetlands.
Notably, this definition is a great deal shorter than the 2015 iteration of the rule, meaning that less waters fall under the rule. In addition, the new rule contains a much longer list of waters that are not WOTUS:
- Waters or water features that are not identified in the definition of WOTUS, above;
- Groundwater, including groundwater drained through subsurface drainage systems;
- Ephemeral features, including ephemeral streams, swales, gullies, rills, and pools;
- Diffused stormwater run-off and directional sheet flow over upland;
- Ditches that are not territorial seas, waters used in foreign commerce, or tributaries, and those portions of ditches constructed in some adjacent wetlands;
- Prior converted cropland;
- Artificially irrigated areas, including fields flooded for agricultural production, that would revert to upland should application of irrigation water to that area cease;
- Artificial lakes and ponds, including water storage reservoirs and farm, irrigation, stock watering, and log cleaning ponds, constructed or excavated in upland or in non-jurisdictional waters, so long as those artificial lakes and ponds are not impoundments of jurisdictional waters that are connected the territorial seas, or waters used in interstate or foreign commerce;
- Water-filled depressions constructed or excavated in upland or in non-jurisdictional waters incidental to mining or construction activity, and pits excavated in upland or in non-jurisdictional waters for the purpose of obtaining fill, sand, or gravel;
- Stormwater control features constructed or excavated in upland or in nonjurisdictional waters to convey, treat, infiltrate, or store stormwater run-off;
- Groundwater recharge, water reuse, and wastewater recycling structures, including detention, retention, and infiltration basins and ponds, constructed or excavated in upland or in non-jurisdictional waters; and
- Waste treatment systems.”
