Indicate Which of the Following Apply:
A. Preliminary Determination
_ There are waters, including wetlands, on the above described project area, that may be subject to Section 404 of the
Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). The
waters, including wetlands, have been delineated, and the delineation has been verified by the Corps to be sufficiently
accurate and reliable. Therefore this preliminary jurisdiction determination may be used in the permit evaluation process,
including determining compensatory mitigation. For purposes of computation of impacts, compensatory mitigation
requirements, and other resource protection measures, a permit decision made on the basis of a preliminary JD will treat all
waters and wetlands that would be affected in any way by the permitted activity on the site as if they are jurisdictional
waters of the U.S. This preliminary determination is not an appealable action under the Regulatory Program
Administrative Appeal Process (Reference 33 CFR Part 331). However, you may request an approved JD, which is an
appealable action, by contacting the Corps district for further instruction.
_ There are wetlands on the above described property, that may be subject to Section 404 of the Clean Water Act
(CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). However, since the
waters, including wetlands, have not been properly delineated, this preliminary jurisdiction determination may not be
used in the permit evaluation process. Without a verified wetland delineation, this preliminary determination is merely an
effective presumption of CWA/RHA jurisdiction overall of the waters, including wetlands, at the project area, which is
not sufficiently accurate and reliable to support an enforceable permit decision. We recommend that you have the
waters of the U.S. on your property delineated. As the Corps may not be able to accomplish this wetland delineation in a
timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps.
B. Approved Determination
_ There are Navigable Waters of the United States within the above described property subject to the permit requirements of
Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403) and Section 404 of the Clean Water Act (CWA)(33 USC
§ 1344). Unless there is a change in law or our published regulations, this determination may be relied upon for a period
not to exceed five years from the date of this notification.
_ There are waters of the U.S., including wetlands, on the above described project area subject to the permit requirements
of Section 404 of the Clean Water Act (CWA) (33 USC § 1344). Unless there is a change in the law or our published
regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification.

We recommend you have the waters of the U.S. on your property delineated. As the Corps may not be able to
accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that
can be verified by the Corps.
_ The waters of the U.S., including wetlands, on your project area have been delineated and the delineation has been
verified by the Corps. If you wish to have the delineation surveyed, the Corps can review and verify the survey upon
completion. Once verified, this survey will provide an accurate depiction of all areas subject to CWA and/or RHA
jurisdiction on your property which, provided there is no change in the law or our published regulations, may be relied
upon for a period not to exceed five years.
_ The waters of the U.S., including wetlands, have been delineated and surveyed and are accurately depicted on the plat
signed by the Corps Regulatory Official identified below on . Unless there is a change in the law or our
published regulations, this determination may be relied upon for a period not to exceed five years from the date of this
notification.
X There are no waters of the U.S., to include wetlands, present on the above described project area which are subject to the
permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law or our
published regulations, this determination may be relied upon for a period not to exceed five years from the date of this
notification.
_ The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act
(LAMA). You should contact the Division of Coastal Management in Morehead City, NC, at [phone] to
determine their requirements.
Placement of dredged or fill material within waters of the US, including wetlands, without a Department of the Army permit
may constitute a violation of Section 301 of the Clean Water Act (33 USC § 1311). Placement of dredged or fill material,
construction or placement of structures, or work within navigable waters of the United States without a Department of the
Army permit may constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act (33 USC § 401 and/or 403). If
you have any questions regarding this determination and/or the Corps regulatory program, please contact Ms. Samantha
Dailey at [phone], ext. 22 or Samantha.J.Daileynusace.army.mil.
C. Basis For Determination: Refer to the enclosed Approved Jurisdictional Determination Form (Rapanos
Form)
D. Remarks:
E. Attention USDA Program Participants
This delineation/determination has been conducted to identify the limits of Corps' Clean Water Act jurisdiction for the
particular site identified in this request. The delineation/determination may not be valid for the wetland conservation
provisions of the Food Security Act of 1985. If you or your tenant are USDA Program participants, or anticipate participation
in USDA programs, you should request a certified wetland determination from the local office of the Natural Resources
Conservation Service, prior to starting work.

Indicate presence of waters of U.S. in review area (check all that apply): '
❑ TNWs, including territorial seas
❑ Wetlands adjacent to TNWs
❑ Relatively permanent waters2 (RPWs) that flow directly or indirectly into TNWs
❑ Non-RPWs that flow directly or indirectly into TNWs

❑ Wetlands adjacent to non-RPWs that flow directly or indirectly into TNWs
❑ Impoundments of jurisdictional waters
❑ Isolated (interstate or intrastate) waters, including isolated wetlands
b. Identify (estimate) size of waters of the U.S. in the review area:

Wetlands: acres.
c. Limits (boundaries) of jurisdiction based on: —
Elevation of established OHWM (if known):
2. Non -regulated waters/wetlands (check if applicable):3
® Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional.
Explain: One (1) non -jurisdictional ditch (--450 linear feet) was identified within the approximate 0.3 acre project
boundary. The feature did not exhibit an ordinary high water mark, nor did it meet the hydrophytic vegetation,
wetland hydrology, or hydric soil criteria of the 1987 Corps of Engineers Wetland Delineation Manual and the
Atlantic and Gulf Coastal Plain Regional Supplement. Soil samples were collected upslope and downslope of the
ditch areas and did not exhibit any saturation, nor was there any observable evidence that water from the ditch
contributed any flow, via either surface or subsurface connection, to a downslope receiving stream/lake. Therefore,
Boxes checked below shall be supported by completing the appropriate sections in Section III below.
z For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally"
(e.g., typically 3 months).
s Supporting documentation is presented in Section III.F.

-2-
this feature is considered non -jurisdictional and is not subject to permit requirements of Section 404 of the Clean
Water Act (33 USC 1344).
SECTION III: CWA ANALYSIS
A. TNWs AND WETLANDS ADJACENT TO TNWs
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete
Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections HI.A.1 and 2
and Section III.D.1.; otherwise, see Section III.B below.
1. TNW
Identify TNW:
Summarize rationale supporting determination:
2. Wetland adjacent to TNW
Summarize rationale supporting conclusion that wetland is "adjacent':
B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) 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 Rapanos 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 IH.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant 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 waterbody4 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 III.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.

(iii) Chemical Characteristics:
Characterize tributary (e.g., water color is clear, discolored, oily film; water quality; general watershed characteristics, etc.).
Explain:
Identify specific pollutants, if known:
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.
6A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where
the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow
regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

Summarize overall biological, chemical and physical functions being performed:
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:
Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain
findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D:
Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into

Explanation: The streams) listed above has been located on the most recent published NRCS Soil Survey of
Johnston County, North Carolina and/or the most recent copy of the USGS Topographic map at a 1:24,000 scale.
Each stream that is checked "Not Subject" has been determined to not be at least intermittent or is not present.
Streams that are checked "Subject" have been located on the property and possess characteristics that qualify it to be
at least an intermittent stream. There may be other streams located on the property that do not show up on the maps
referenced above but may be considered jurisdictional according to the US Army Corps of Engineers.
This on -site determination shall expire rive (5) years from the date of this letter. Landowners or affected
parties that dispute a determination made by the DWR may request a determination by the Director. An
appeal request must be made within sixty (60) days of date of this letter. A request for a determination by the
