New Definition for “Waters of the United States” What Developers Need to Know



Land developers seeking to build anywhere near coastal waters, lakes, ponds, streams, waterways or wetlands, be aware that U.S. Army Corps of Engineers (“ACOE”) and the United States Environmental Protection Agency (“EPA”) are proposing a rule to change the definition of “waters of the United States” that will effectively expand ACOE jurisdiction to require dredge and fill permits. Since the individual 404 permitting process is often long, drawn out and costly, the proposed change has the potential to impact the profitability of projects if the proposed rule is adopted.

According to the public notice issued in connection with the proposed rule:

The proposed rule was developed to enhance protection for the nation’s public health and aquatic resources, and increase Clean Water Act program predictability and consistency by increasing clarity as to the scope of ‘waters of the United States’ protected under the Act.

Despite this stated intent, the proposed rule will not necessarily provide predictability and consistency for developers and will definitely expand ACOE permitting jurisdiction.

Jurisdictional Waters of the United States Defined

Waters in the categories listed below would be jurisdictional “waters of the United States” by rule. The proposed rule would apply for all sections of the CWA (i.e. Section 404 and 402) and would include:

  • Traditional navigable waters
  • Interstate waters, including interstate wetlands
  • The territorial seas
  • Impoundments of traditional navigable waters, and tributaries of such waters, including adjacent wetlands

Dredge and Fill Permit now Required

Under the proposed rule, landowners and developers whose projects impact any of these “waters of the United States” would be required to obtain an ACOE dredge and fill permit to impact the waterbody. According to the public notice:

The agencies emphasize that the categorical finding of jurisdiction for tributaries and adjacent waters was not based on the mere connection of a water body to downstream waters, but rather a determination that the nexus, alone or in combination with similarly situated waters in the region, is significant based on data, science, the CWA, and case law.

The case law in question includes two U.S. Supreme Court cases: U.S. v. Riverside Bayview, Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers and Rapanos v. United States both of which limited ACOE jurisdiction over waters the Court found not to be “waters of the United States.”

U.S. Army Corps of Engineers Scope Broadened

Despite EPA’s assertion to the contrary on its webpage devoted to this proposed rule, the new proposed definition broadens the scope of ACOE jurisdiction because under current rules and case law, individualized analysis of wetlands and more intermittent and disconnected water bodies is required before ACOE can assert jurisdiction.  Additionally, the inclusion of tributaries (broadly defined) that connect to navigable waters would arguably allow ACOE to assert jurisdiction over storm water conveyance ditches and pipes that outfall to the Atlantic or Gulf of Mexico in Florida, and any wetlands that have developed adjacent to those ditches and pipes.  In the west, intermittent streams could now be subject to jurisdiction as well (even when there is no water in them).

“Other Waters” Also Effected

The proposed rule also contains a catch-all definition for “other waters” that might be “waters of the United States” if, either alone or in combination with similarly situated “other waters” in the region, they have a “significant nexus” to a traditional navigable water, interstate water, or the territorial seas. While the proposed rule offers a definition of significant nexus and purports to explain how similarly situated “other waters” in the region should be identified, the promised clarity is missing, and the regionality of the required analysis is daunting.

Use of “absolute standards such as flow rates, surface acres, or minimum number of functions” is expressly disavowed. Rather, the case-by-case method for determining the significance of “other waters” will examine whether such waters have effects that are “more than speculative or insubstantial.” 79 Fed. Reg. at 22211.  Last time I checked there was no ASTM standard or tool for definitively measuring “more than speculative or insubstantial,” (even if that is what the U.S. Supreme Court said.) The result will be delay, confusion and added costs; particularly because ACOE is shrinking staff as a result of budget cuts.

Under the proposal, “waters of the United States” will not include waste treatment systems designed consistent with the requirements of the CWA, prior converted cropland, water transfers, certain farm conservation activities and certain manmade ditches. These exclusions are consistent with long standing ACOE practice.
