A. TNWs AND WETLANDS ADJACENT TO TNWs
' Boxes chedced below shall be supported by completing the appropriate sections in Section Ili below.
'- For purposes of this form, an RPW is detined as a tributary that is not a TN W and that typically flows year-round or has continuous flow at least
"seasonally" (e.g., typically 3 months).
j Supporting documentation is presented in Section iil.F.

The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW,
complete Section III.A.l and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete
Sections III.A.1 and 2 and Section III.D.I.; otherwise, see Section III.B below.
1. TNW
Identify TNW:
Sumrnarize rationale supporting determination:
2. Wetlandadjacent to TNW
Summarize rationale supporting conclusion that wetland is "adjacent":
B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNV1') AND ITS ADJACENT WETLANDS (IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and
it helps determine whether or not the standards for jurisdiction established under Rapa��os have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively
permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally
(e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictionaL If the aquatic resource is not a
TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly
abutting a tributary with perennial flow, skip to Section III.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a signi�cant nexus evaluation. Corps
districts and EPA regions will include in the record any available information that documents the existence of a
significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any)
and a traditional navigable water, even though a significant nexus finding is not required as a matter of law.
If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to
determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the
significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This
significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is
used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD
covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite
wetlands, and Section I11.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination
whether a significant nexus exists is determined in Section III.0 below.

C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions
performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical,

and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in
combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical,
physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not
limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and
the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant
nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between
a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely
determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos
Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example:
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood
waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions
for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and
organic carbon that support downstream foodwebs'?
• Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical,
chemical, or biological integrity of the TNW?
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be
documented below:

adjacent wetlands, then go to Section IILD: .
