So….why does EPA say it doesn’t?

Tributaries - The Big Questions 
Does this rule go beyond current federal

The draft rule is very similar to the 2007 Post- 
Rapanos guidance used by the Corps.

Tributaries - The Big Questions 
Does this rule go beyond current federal

When it comes to Section 404 (dredge and fill), the 
Corps exerts its reach quite far into the 
watershed - to the end of the tributary.

This is a Big Change.

Definitions 
• (1) Adjacent: The term adjacent means 
bordering, contiguous or neighboring. Waters, 
including wetlands, separated from other 
waters of the United States by man-made 
dikes or barriers, natural river berms, beach 
dunes and the like are “adjacent waters.”
resourceful. naturally. 
Definitions 
• (2) Neighboring: The term neighboring, 
includes waters located within the riparian 
area or floodplain of a water [of the US] or 
waters with a shallow subsurface hydrologic 
connection or confined surface hydrologic 
connection to such a jurisdictional water.
resourceful. naturally. 
Definitions 
• (3) Riparian area: The term riparian area means 
an area bordering a water where surface or 
subsurface hydrology directly influence the 
ecological processes and plant and animal 
community structure in that area. Riparian areas 
are transitional areas between aquatic and 
terrestrial ecosystems that influence the 
exchange of energy and materials between those 
ecosystems.
resourceful. naturally. 
Definitions 
• (4) Floodplain: The term floodplain means an 
area bordering inland or coastal waters that 
was formed by sediment deposition from such 
water under present climatic conditions and is 
inundated during periods of moderate to high 
water flows.
resourceful. naturally. 
Waste Treatment 
40 CFR 122.2 Definitions 
• Waste treatment systems, including treatment ponds or 
lagoons … are not waters of the United States. This 
exclusion applies only to manmade bodies of water which 
neither were originally created in waters of the United 
States …nor resulted from the impoundment of waters of 
the United States. [See Note 1 of this section.] 
• NOTE: At 45 FR 48620, July 21, 1980, the Environmental 
Protection Agency suspended until further notice in §122.2, 
the last sentence, beginning “This exclusion applies . . .” in 
the definition of “Waters of the United States.” This revision 
continues that suspension.1
resourceful. naturally. 
Waste Treatment 
New Definition 
• The following are not “waters of the United 
States” 
• (1) Waste treatment systems, including 
treatment ponds or lagoons, designed to meet 
the requirements of the Clean Water Act.
resourceful. naturally. 
Definitions 
• (5) Tributary: The term tributary means a water physically characterized by the 
presence of a bed and banks and ordinary high water mark, as defined at 33 CFR § 
328.3(e), which contributes flow, either directly or through another water, to a 
water identified in paragraphs (a)(1) through (4) of this section. In addition, 
wetlands, lakes, and ponds are tributaries (even if they lack a bed Page 328 of 370 
and banks or ordinary high water mark) if they contribute flow, either directly or 
through another water to a water identified in paragraphs (a)(1) through (3) of this 
section. A water that otherwise qualifies as a tributary under this definition does 
not lose its status as a tributary if, for any length, there are one or more man-made 
breaks (such as bridges, culverts, pipes, or dams), or one or more natural breaks 
(such as wetlands at the head of or along the run of a stream, debris piles, boulder 
fields, or a stream that flows underground) so long as a bed and banks and an 
ordinary high water mark can be identified upstream of the break. A tributary, 
including wetlands, can be a natural, man-altered, or man-made water and 
includes waters such as rivers, streams, lakes, ponds, impoundments, canals, and 
ditches not excluded in paragraphs (b)(3) or (4) of this section.
resourceful. naturally. 
Definitions 
(5) Tributary: The term tributary means a water 
physically 
– characterized by the presence of a bed and 
banks and ordinary high water mark, 
– which contributes flow, either directly or 
through another water, to a water (of the 
U.S.).
resourceful. naturally. 
Definitions 
• (5) Tributary: 
• Wetlands, lakes, and ponds are tributaries 
– (even if they lack a bed and banks or 
ordinary high water mark) if they 
– contribute flow, either directly or through 
another water to a water (of the U.S.)
resourceful. naturally. 
Definitions 
• (5) Tributary: 
• A water that otherwise qualifies as a tributary does not 
lose its status as a tributary if, 
– for any length, there are one or more man-made 
breaks (such as bridges, culverts, pipes, or dams), 
– or one or more natural breaks (such as wetlands at 
the head of or along the run of a stream, debris 
piles, boulder fields, or a stream that flows 
underground) 
– so long as a bed and banks and an ordinary high 
water mark can be identified upstream of the break.

Definitions 
• (5) Tributary: 
• A tributary, including wetlands, can be a 
natural, man-altered, or man-made water and 
includes waters such as rivers, streams, lakes, 
ponds, impoundments, canals, and ditches 
not excluded in this rule.
resourceful. naturally. 
Definitions 
(7) Significant nexus: The term significant nexus 
means that a water, including wetlands, either 
alone or in combination with other similarly 
situated waters in the region (i.e., the watershed 
that drains to the nearest water [of the U.S.] 
significantly affects the chemical, physical, or 
biological integrity of a water [of the U.S.].
resourceful. naturally. 
Definitions 
(7) Significant nexus (cont’d) For an effect to be 
significant, it must be more than speculative or 
insubstantial. Other waters, including wetlands, are 
similarly situated when they perform similar 
functions and are located sufficiently close together 
or sufficiently close to a “water of the United 
States” so that they can be evaluated as a single 
landscape unit with regard to their effect on the 
chemical, physical, or biological integrity of a water 
[of the U.S.].
