EASLEY LYNDO TIPPET GOVERNOR SECRETARY rr pv ~ November 1, 2007 V - ~ SUBJECT: Stokes County -Bridge # 242 on SR 1127, Temporary Rock Causeway ~ ~ Mr. John Thomas 2 ~ US Army Corps of Engineers 6508 Falls of the Neese Road, Suite 120 0 ~ Raleigh, NC 27615-6814 ~. Dear Mr. Thomas, e0 In an effort to obtain the necessary permits for a temporary rock causeway, we areproviding a pre- y construction notification application with supporting documentation. This is a permit for a defined perennial stream, the Little Yadkin River, with distinct stream banks. There will be 40 feet of temporary f- stream impacts, and .006 acres of temporary surface water impacts for the construction of a temporary rock ~ causeway. The causeway will be constructed of Class II riprap placed up to 1' below the natural ground elevation at Bent # 1. It will then be capped off with 1' of class A riprap to provide a stable pad for a drilling rig. This causeway is necessary to create a work area for the drilling rig at Bent #1. No endangered species were found on 10/19/07. We believe this project can be accomplished under Nationwide Permit 33. .After completion of the drilled shafts, the causeway will be removed and the stream profile will be returned to its original condition. The stream banks will be seeded with a riparian mix and lined with coir fiber matting. By copy of this letter, we are also seeking approval from the NC Wildlife Resources Commission, NC Department of Natural Resources -Water Quality, and the State Historic Preservation Office. Therefore, we are submitting the enclosed material to them. For DWQ, the WB5 number for this project is 37818. If you have any questions, comments or need additional information after reviewing this material, please contact me at (336) 703-6500. Thank you for your cooperation in this matter.

Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http~//h2o enr.state.nc.us/ncwetlands/strm~ide.html. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A Page 10 of 13 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP).

Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. z For purposes of this form, an RP W is defined as a tributary that is not a T'N W and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). ' Supporting documentation is presented in Section III.F. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWa 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.l and 2 and Section III.D.1.; otherwise, see Section ]II.$ below. 1. TNW Identify TNW: Summarize rationale supporting detemunation: 2. Wetland adjacent to TNW Sununarize 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 ofthe 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. Ifthe 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, sltip to Section III.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 news 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. Tf the JD covers a tributary with adjacent wetlands, complete Section lII.B.I 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 lII.C below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 8 square miles Drainage area: 8 square miles Average annual rainfall: 30 inches Average annual snowfall: 2 inches (ii) Physical Characteristics: (a) Relationship with TNW: ® Tributary flows directly into TNW. ^ Tributary flows through Pick List tributaries before entering T]WV. Project waters are 5-10 river miles from TNW. Project waters aze 1(or less) river miles from RPW. Project waters are 5-10 aerial (straight) miles from TNW.

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 titan a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant news 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 ita 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 TNW7 • 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: 1.
