Version: May 2017 Page 3 Jurisdictional Determination Request F. JURISDICTIONAL DETERMINATION (JD) TYPE (Select One) ❑� I am requesting that the Corps provide a preliminary JD for the property identified herein. A Preliminary Jurisdictional Determination (PJD) provides an indication that there may be "waters of the United States" or "navigable waters of the United States"on a property. PJDs are sufficient as the basis for permit decisions. For the purposes of permitting, all waters and wetlands on the property will be treated as if they are jurisdictional "waters of the United States". PJDs cannot be appealed (33 C.F.R. 331.2); however, a PJD is "preliminary" in the sense that an approved JD can be requested at any time. PJDs do not expire. ❑ I am requesting that the Corps provide an approved JD for the property identified herein. An Approved Jurisdictional Determination (AJD) is a determination that jurisdictional "waters of the United States" or "navigable waters of the United States" are either present or absent on a site. An approved JD identifies the limits of waters on a site determined to be jurisdictional under the Clean Water Act and/or Rivers and Harbors Act. Approved JDs are sufficient as the basis for permit decisions. AJDs are appealable (33 C.F.R. 331.2). The results of the AJD will be posted on the Corps website. A landowner, permit applicant, or other "affected party" (33 C.F.R. 331.2) who receives an AJD may rely upon the AJD for five years (subject to certain limited exceptions explained in Regulatory Guidance Letter 05- 02). ❑ I am unclear as to which JD I would like to request and require additional information to inform my decision. G. ALL REQUESTS Map of Property or Project Area. This Map must clearly depict the boundaries of the review area. ✓❑ Size of Property or Review Area 868 acres. ❑ The property boundary (or review area boundary) is clearly physically marked on the site.

REQUESTS FROM CONSULTANTS Project Coordinates (Decimal Degrees): Latitude: Longitude 35.9109 -78.8653 A legible delineation map depicting the aquatic resources and the property/review area. Delineation maps must be no larger than I Ix17 and should contain the following: (Corps signature of submitted survey plats will occur after the submitted delineation map has been reviewed and approved).6 ■ North Arrow ■ Graphical Scale ■ Boundary of Review Area ■ Date ■ Location of data points for each Wetland Determination Data Form or tributary assessment reach. For Approved Jurisdictional Determinations: ■ Jurisdictional wetland features should be labeled as Wetland Waters of the US, 404 wetlands, etc. Please include the acreage of these features. ■ Jurisdictional non -wetland features (i.e. tidal/navigable waters, tributaries, impoundments) should be labeled as Non -Wetland Waters of the US, stream, tributary, open water, relatively permanent water, pond, etc. Please include the acreage or linear length of each of these features as appropriate. ■ Isolated waters, waters that lack a significant nexus to navigable waters, or non - jurisdictional upland features should be identified as Non -Jurisdictional. Please include a justification in the label regarding why the feature is non jurisdictional (i.e. "Isolated", "No Significant Nexus", or "Upland Feature"). Please include the acreage or linear length of these features as appropriate. For Preliminary Jurisdictional Determinations: ■ Wetland and non -wetland features should not be identified as Jurisdictional, 404, Waters of the United States, or anything that implies jurisdiction. These features can be identified as Potential Waters of the United States, Potential Non -wetland Waters of the United States, wetland, stream, open water, etc. Please include the acreage and linear length of these features as appropriate. aCompleted Wetland Determination Data Forms for appropriate region (at least one wetland and one upland form needs to be completed for each wetland type) 6 Please refer to the guidance document titled "Survey Standards for Jurisdictional Determinations" to ensure that the supplied map meets the necessary mapping standards. http://www.saw.usace.army.mil/Missions/Re ulatory-Permit- Pro gram/Jurisdiction/ Version: May 2017 Page 5 Jurisdictional Determination Request aCompleted appropriate Jurisdictional Determination form • PJDs, please complete a Preliminary Jurisdictional Determination Form' and include the Aquatic Resource Table • AJDs, please complete an Approved Jurisdictional Determination Form' Vicinity Map Aerial Photograph USGS Topographic Map Soil Survey Map Other Maps, as appropriate (e.g. National Wetland Inventory Map, Proposed Site Plan, previous delineation maps, LIDAR maps, FEMA floodplain maps) ❑ Landscape Photos (if taken) aNCSAM and/or NCWAM Assessment Forms and Rating Sheets NC Division of Water Resources Stream Identification Forms Other Assessment Forms ' www.saw.usace.gM.mil/Portals/59/docs/re ug latorregdocs/JD/RGL 08-02_App_A_Prelim _JD_Form _fillable.pdf ' Please see http://www.saw.usace.army.mil/Missions/Re ug latory-Permit-Proaram/Jurisdiction/ Principal Purpose: The information that you provide will be used in evaluating your request to determine whether there are any aquatic resources within the project area subject to federal jurisdiction under the regulatory authorities referenced above.

Site number Latitude (decimal degrees) Longitude (decimal degrees) Estimated amount of aquatic resource in review area (acreage and linear feet, if applicable) Type of aquatic resource (i.e., wetland vs. non -wetland waters) Geographic authority to which the aquatic resource "may be" subject (i.e., Section 404 or Section 10/404) 1) The Corps of Engineers believes that there may be jurisdictional aquatic resources in the review area, and the requestor of this PJD is hereby advised of his or her option to request and obtain an approved JD (AJD) for that review area based on an informed decision after having discussed the various types of JDs and their characteristics and circumstances when they may be appropriate. 2) In any circumstance where a permit applicant obtains an individual permit, or a Nationwide General Permit (NWP) or other general permit verification requiring "pre - construction notification" (PCN), or requests verification for a non -reporting NWP or other general permit, and the permit applicant has not requested an AJD for the activity, the permit applicant is hereby made aware that: (1) the permit applicant has elected to seek a permit authorization based on a PJD, which does not make an official determination of jurisdictional aquatic resources; (2) the applicant has the option to request an AJD before accepting the terms and conditions of the permit authorization, and that basing a permit authorization on an AJD could possibly result in less compensatory mitigation being required or different special conditions; (3) the applicant has the right to request an individual permit rather than accepting the terms and conditions of the NWP or other general permit authorization; (4) the applicant can accept a permit authorization and thereby agree to comply with all the terms and conditions of that permit, including whatever mitigation requirements the Corps has determined to be necessary; (5) undertaking any activity in reliance upon the subject permit authorization without requesting an AJD constitutes the applicant's acceptance of the use of the PJD; (6) accepting a permit authorization (e.g., signing a proffered individual permit) or undertaking any activity in reliance on any form of Corps permit authorization based on a PJD constitutes agreement that all aquatic resources in the review area affected in any way by that activity will be treated as jurisdictional, and waives any challenge to such jurisdiction in any administrative or judicial compliance or enforcement action, or in any administrative appeal or in any Federal court; and (7) whether the applicant elects to use either an AJD or a PJD, the JD will be processed as soon as practicable. Further, an AJD, a proffered individual permit (and all terms and conditions contained therein), or individual permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it becomes appropriate to make an official determination whether geographic jurisdiction exists over aquatic resources in the review area, or to provide an official delineation of jurisdictional aquatic resources in the review area, the Corps will provide an AJD to accomplish that result, as soon as is practicable. This PJD finds that there "may be" waters of the U.S. and/or that there "may be" navigable waters of the U.S. on the subject review area, and identifies all aquatic features in the review area that could be affected by the proposed activity, based on the following information: SUPPORTING DATA.
