-2- <br /> A. TNWs AND WETLANDS ADJACENT TO TNWs <br /> The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW,complete <br /> Section III.A.1 and Section III.D.1,only;if the aquatic resource is a wetland adjacent to a TNW,complete Sections III.A.1 and 2 <br /> and Section III.D.I.;otherwise,see Section III.B below. <br /> 1. TNW <br /> Identify TNW: <br /> Summarize rationale supporting determination: <br /> 2. Wetland adjacent to TNW <br /> Summarize rationale supporting conclusion that wetland is"adjacent': <br /> B. CHARACTERISTICS OF TRIBUTARY(THAT IS NOT A TNW)AND ITS ADJACENT WETLANDS(IF ANY): <br /> This section summarizes information regarding characteristics of the tributary and its adjacent wetlands,if any,and it helps <br /> determine whether or not the standards for jurisdiction established under Rapanos have been met. <br /> The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are"relatively permanent <br /> waters"(RPWs),i.e.tributaries that typically flow year-round or have continuous flow at least seasonally(e.g.,typically 3 <br /> months).A wetland that directly abuts an RPW is also jurisdictional.If the aquatic resource is not a TNW,but has year-round <br /> (perennial)flow,skip to Section IH.D.2.If the aquatic resource is a wetland directly abutting a tributary with perennial flow, <br /> skip to Section III.D.4. <br /> A#ctland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation.Corps districts and <br /> EPA regions will include in the record any available information that documents the existence of a significant nexus between a <br /> relatively permanent tributary that is not perennial(and its adjacent wetlands if any)and a traditional navigable water,even <br /> though a significant nexus finding is not required as a matter of law. <br /> If the waterbody°is not an RPW,or a wetland directly abutting an RPW,a JD will require additional data to determine if the <br /> waterbody has a significant nexus with a TNW.If the tributary has adjacent wetlands,the significant nexus evaluation must <br /> consider the tributary in combination with all of its adjacent wetlands.This significant nexus evaluation that combines,for <br /> analytical purposes,the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is <br /> the tributary,or its adjacent wetlands,or both.If the JD covers a tributary with adjacent wetlands,complete Section III.B.1 for <br /> the tributary,Section III.B.2 for any onsite wetlands,and Section III.B.3 for all wetlands adjacent to that tributary,both onsite <br /> and offsite.The determination whether a significant nexus exists is determined in Section III.0 below. <br /> 1. Characteristics of non-TNWs that flow directly or indirectly into TNW <br /> (i) General Area Conditions: <br /> Watershed size: <br /> Drainage area: <br /> Average annual rainfall: inches <br /> Average annual snowfall: inches <br /> (ii) Physical Characteristics: <br /> (a) Relationship with TNW: <br /> ❑Tributary flows directly into TNW. <br /> ❑Tributary flows through i tributaries before entering TNW. <br /> Project waters are river miles from TNW. <br /> Project waters are river miles from RPW. <br /> Project waters are aerial(straight)miles from TNW. <br /> Project waters are aerial(straight)miles from RPW. <br /> Project waters cross or serve as state boundaries.Explain: <br /> Identify flow route to TNW5: <br /> Tributary stream order,if known: <br /> (b) General Tributary Characteristics(check all that apply): <br /> °Note that the Instructional Guidebook contains additional information regarding swales,ditches,washes,and erosional features generally and in the and <br /> West <br /> s Flow route can be described by identifying,e.g.,tributary a,which flows through the review area,to flow into tributary b,which then flows into TNW <br />
