Benton Water Treatment Plant project -Rerouting of a previously permitted transmission main Action ID Numbers 200320193, 200620626-200620628, and Nationwide Permit Date: Numbers 12 (Utility Line Activities) and 39 (Residential, Commercial, and Institutional 12 February 2008 Developments) Contact: Linda Diebolt Dear Ms Karoly: Phone: In association with construction of the Dempsey E. Benton Water Treatment Plant 919.854.1282 (WTP), upgrades to the Lake Benson and Lake Wheeler dams, and construction of transmission mains, Nationwide Permit (NWP) Numbers 12 and 39 were issued by Email: Iinda.dieboltCc?arcadis-us.com the U.S. Army Corps of Engineers (USAGE). To better meet the existing and forecasted needs of the communities that will be served by the Dempsey E. Benton Our ref: WTP, a transmission main route that was included in the aforementioned NWP 12 NC703027.1000 has been modified. The new transmission main route includes four blow off locations that will permanently impact 44 linear feet (0.004 acre) of stream. The new transmission main route, including the four aforementioned blow offs, will impact 324 linear feet (0.053 acre) of stream and 0.048 acre of wetlands. The new transmission main route traverses 6 streams (Wildcat Creek will be crossed twice) and 2 wetlands. The previously permitted transmission main route crossed 9 streams and 2 wetlands. The new transmission main route, compared to the previously permitted transmission main route, decreases the temporary stream impacts by 36 feet (0.014 acre) and decreases temporary wetland impacts by 0.94 acre. Permanent impacts to 0.26 acre of wetlands, which were previously permitted and for which mitigation was secured through the North Carolina Ecosystem Enhancement Program, are still proposed to occur. The permanent wetland impacts are associated with construction of the Dempsey E. Benton WTP facility and are not related to the Imagine the result ARCADIS Mr. Jamie Shern 12 February 2008 transmission main. Permanent impacts to two streams, which total 43 linear feet of impact, were previously permitted and are still proposed to occur. Additional permitted impacts that are expected to occur are impacts associated with a second transmission main that is not being relocated. In response to the changes in impacts associated with relocation of the transmission main route, we have provided the attached documentation. ^ Pre-Construction Notification (PCN) Application Form -The attached PCN Application Form was generated to provide information on the impacts associated with only the new transmission main route and the four associated new blow offs. Previously permitted impacts that will no longer occur due to the relocation of the transmission main route and previously permitted impacts that will occur regardless of the relocation of the transmission main route are not included in the PCN Application Form. The attached PCN Application Form includes: o Table 1, which provides the site coordinates for the impact locations o Figure 1, Site Location Map o Figure 2, Soils Map o Figures 3 through 5, which depict the location of the new transmission main, the impact locations, and the impact amounts o Construction details for anti-seep collars and blow off discharge stabilization areas o Routine Jurisdictional Determination Form - An upland and wetland Jurisdictional Determination Form is provided for Wetland 4. o Approved Jurisdictional Determination Form -Approved Jurisdictional Determination Forms are provided for Streams 20 through 24. ^ Additionallnformation o Sheet 1 through Sheet 10 - These figures show the previously permitted transmission main route, the permitted impact totals, and whether the permitted impacts will still occur.

Name of project: City of Raleigh, Dempsey E. Benton Water Treatment Plant, Rerouting of a Previously Permitted Finished Water Transmission Main 2. T.LP. Project Number or State Project Number (NCDOT Only): 3. Property Identification Number (Tax PIN): The new transmission main will be located in existing and proposed easements. 4. Location County: Wake Nearest Town: Garner Subdivision name (include phase/lot number): Directions to site (include road numbers/names, landmarks, etc.): The new transmission main route extends north along Benson Road (Highway 50) from the proposed Dempsey Benton Water Treatment Plant (WTP) to New Rand Road. The transmission main runs north along New Rand Road, then turns west and runs along. Rand Mill Road. The transmission main crosses through a City of Raleigh baseball field and then runs through a power line easement and wooded, undeveloped land to Haywood Street. The transmission main continues north along Montague Street, then turns west along West Main Street. The transmission main follows West Main Street to Benson Road, where it starts paralleling a railroad easement. The transmission main parallels the railroad easement north to Rush Street. The transmission main runs west along Rush Street, crosses Hammond Road, then turns north and parallels Newbold Street to South Wilmington Street. The transmission main runs north along South Wilmington Street to the E.B. Bain WTP. 5. Site coordinates (For linear projects, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct waterbody.) Decimal Degrees (6 digits minimum): See Table 1 (attached) 6. Property size (acres): ~ 38 acres (7.9-miles long, 40-foot wide easement) Updated 1 l/1/2005 Page 6 of 16 7. Name of nearest receiving body of water: Lake Benson/Swift Creek 8. River Basin: Neuse River Basin (Note -this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://h2o.enr.state.nc.us/admin/maps/.) 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: Much of the land crossed by the transmission main route consists of roadway easements and wooded, undeveloped land adjacent to a railroad easement Bottomland hardwood forest is the dominant riparian vegetation community at most of the stream crossings 10. Describe the overall project in detail, including the type of equipment to be used: A new, approximately 7.9 mile long 48-inch finished water transmission main will be constructed from the Dempsey E. Benton WTP site to the E B Bain WTP site Transmission main construction will primarily utilize bulldozers for land clearing and backhoes for trench excavation and back-filling. The transmission main will be located primarily within existing North Carolina Department of Transportation (NCDOT) rights-of-way along Benson Road (Highway 50), New Rand Road, Rand Mill Road Haywood Street Montague Street West Main Street, Rush Street and South Wilmington Street Four blow offs will be constructed along the transmission main and will discharge into the adjacent streams 11. Explain the purpose of the proposed work: The City of Raleigh proposes to reactivate Lakes Benson and Wheeler reservoirs as a water supply source primarily to provide the City and surrounding Wake County communities with a reliable and independent water supply source. This project will help initiate solutions to the post-2010 water supply needs and the current drought situation in the project area and for surrounding local communities purchasing water from the City. Reroutin of the pipeline will better meet the existin and forecasted needs of the communities that will be served by the Dempsey E Benton WTP IV. Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain. Include the USACE Action lD Number, DWQ Project Number, application date, and date permits and certifications were issued or withdrawn. Provide photocopies of previously issued permits, certifications or other useful information. Describe previously approved wetland, stream and buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project, list and describe permits issued for prior segments of the same T.I.P. project, along with construction schedules. A jurisdictional determination for the WTP site has been issued b. USACE (Action ID. No. 20030193• February 18 2003) A North Carolina Division of Water Quality (NCDWQ) stream determination for the applicability of Neuse River Riparian Buffer Rules was conducted at the WTP on April 14 2003 and issued August 28 2003 (No NBRRO - 03-199). As noted in the NCDWQ letter the applicability of the buffer rules to Swift Creek and Updated I I/1/2005 Page 7 of l6 Mahlers Creek, the southern and eastern property boundaries, were not in question, and riparian areas along these creeks are assumed to be subject to the buffer rules. Impacts to jurisdictional resources along the force main for the Highway 50 wastewater pump station have been permitted under a separate NWP #12 (Action ID No. 200421195 and 20042 1 1 96; August 16, 2004). A 401 Water Quality Certification for the force main was issued by NCDWO (Proiect No. 04-0921: July 30. 20041. As part of the permitting for the Dempsey E. Benton WTP and its associated pump stations, water transmission mains, intake and discharge sites, and other structures, a NWP #12 and #39 were issued by the U.S. Army Corps of Engineers (USAGE) on April 5, 2006 (Action ID Numbers 200320193 and 200620626-200620628). Approval of 401 Water Quality Certification and Authorization Certificate per the Neuse River Buffer Protection Rules (15A NCAC 2B .0233) with Additional Conditions was issued on November 26, 2006 (NCDWQ Project # 06- 1144). However, after the aforementioned Section 401 and 404 approvals were issued, a portion of the previouslypermitted transmission main was rerouted. Impacts to jurisdictional areas from the rerouted transmission main described herein are less than the impacts included in the April 5, 2006 USAGE NWP #12 and #39 and the November 26, 2006 Water Quality Certification. The information contained within this PCN Application Form reflects only impacts to jurisdictional areas that were not included in the previous permit application. Figures showing the previously permitted transmission main route, the permitted impact totals, and whether the impacts will change with the relocation of the transmission main route are attached to this PCN Application Form (see "Additional Information"). The attached figures also show the impacts associated with the new transmission main route. Wetland and stream summary tables that compare the previously permitted jurisdictional impacts to the impacts associated with the new transmission main route are also provided in the attached "Addition Information" section. Table 1 and Table 2, as provided in the attached "Additional Information," show that the new transmission main route will decrease temporary stream impacts by 361inear feet and 0.014 acre, and decrease temporary wetland impacts by 0.94 acre below the previouslypermitted impacts. V. Future Project Plans Are any future permit requests anticipated for this project? If so, describe the anticipated work, and provide justification for the exclusion of this work from the current application. No future permit requests are anticipated for this Proiect. VI. Proposed Impacts to Waters of the United States/Waters of the State It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to wetlands, open water, and stream channels associated with the project. Each impact must be listed separately in the tables below (e.g., culvert installation should be listed separately from riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts, permanent and temporary, must be listed, and must be labeled and clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) Updated l l/1/2005 Page 8 of 16 should be shown on a delineation map, whether or not impacts are proposed to these systems. Wetland and stream evaluation and delineation forms should be included as appropriate. Photographs may be included at the applicant's discretion. If this proposed impact is strictly for wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. 1. Provide a written description of the proposed impacts: Installation of the transmission main will temporarily impact 0.48 acre of jurisdictional wetland. Temporary wetland impacts, totaling 0.46 acre, will occur within a shrub scrub riverine wetland, Wetland 3. Temporarypacts to Wetland 3 were included in the previous permit; however, relocation of the transmission main reduced the temporarypacts to this wetland by 0.42 acre (0.88 acre of impacts were previously permitted for Wetland 3). Wetland 4 is located adjacent to a stream channel (S23) within an existing sewer easement. Temporary impacts to Wetland 4 consist of 0.02 acre. During construction activities, discharge of excavated material into the adjacent wetlands will be for the minimum period of time necessary for installation of the pipe. These temporary discharges will be fully contained and appropriate erosion control measures will be used. Anti-seep collars will be placed at 150 foot intervals along the transmission line within Wetland 3. A construction detail for the anti-seep collars is attached. Upon completion of the transmission main installation within the wetland areas, the wetland area will be returned to original grade, seeded, and strawed. Fescue grass seed will not be used within the wetland areas. The transmission main will cross 6 jurisdictional stream channels and temporarily impact 324 linear feet of stream. The construction easement is 40 feet in width, for a total temporary stream impact of 0.053 acre. The stream crossings will be performed using coffer dams and all crossings will be at an ankle between 75 degrees and 105 degrees of the surface water intersection. All applicable construction moratoria relative to fish will be adhered to during construction of the transmission main. Upon completion of the transmission main installation, the stream bed and banks will be restored to their on ig nal grade and the banks will be stabilized. Stream stabilization will be provided by the installation of matting along andportions of the stream bank that were disturbed during construction activities. No permanent fill material, such as rip rap, will be placed below Ordinary High Water Mark (OHWM) relative to the stream crossings of the transmission main. Four blow offs will be installed along the transmission main. These blow offs will discharge onto stabilization pads that will diffuse the flow prior to discharge into the stream. A minimal amount of rip rap will be placed within the stream below OHWM in association with the blow offs for stream bank stabilization. The blow offs will permanently impact 44 linear feet and 0.004 acre of stream. A construction detail for the blow offs is attached. 2. Individually list wetland impacts. Types of impacts include, but are not limited to mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams, separately list impacts due to both structure and flooding.

Isolated Waters Do any isolated waters exist on the property? ^ Yes ®No Describe all impacts to isolated waters, and include the type of water (wetland or stream) and the size of the proposed impact (acres or linear feet). Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. 8. Pond Creation If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ^ uplands ^ stream ^ wetlands Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Current land use in the vicinity of the pond: Size of watershed draining to pond: Expected pond surface area: Updated 11/1/2005 Page 1 1 of 16 VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also, discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. Impacts to jurisdictional resources can only be completely avoided by implementation of a no-build scenario. The no- build scenario is not an acceptable option. Impacts to jurisdictional areas have been avoided or minimized to the extent feasible. The new transmission main route decreases the previously permitted impacts. The new transmission main route is located within numerous existing easements and right-of-ways, and adjacent to a railroad easement. A majority of the new transmission main route is located along topographic rides. All stream crossings will be perpendicular to the stream flow to minimize impacts. All impacts along the transmission main route, except minimal permanent impacts associated with the blow offs, will be temporar. ,, s the grade will be restored to preconstruction elevations once the transmission main is installed. VIII. 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 htro://h2o.enr.state.nc.us/ncwetlands/strm~ide.html. 1. 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) Updated 11/1/2005 Page 12 of 16 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. Mitigation is not proposed for wetland or stream impacts described herein. Mitigation credits for permanent wetland impacts associated with construction of the Dempsey E. Benton WTP, as described in the previous PCN Application Form, have been secured through the Ecosystem Enhancement Program (EEP). 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP).

If no, please provide a short narrative description: Dempsey E. Benton WTP Project will not significantl affect growth rate final land use atterns or development densities in the Swift Creek watershed as these have been determined by separate planning and political processes. Yet it is also correct to state that the additional increment of water supply that would be contributed b~project is a necessary factor in achieving and sustaining a normal rate of growth. However the strong local programs in Ip ace by these communities will offset any potential overall cumulative impacts that may result from the proposed project such as growth management planning land mana ement lannin ,open space plans and initiatives erosion and sedimentation control riparian buffers water conservation, stormwater and pollution prevention and planning toward low impact development. A comprehensive discussion of the cumulative impacts of the proposed project is provided in the Environmental Assessment. A Finding of No Significant Impact (FONSI) has been received for this project and was attached to the previously submitted PCN Ap lication Form. XV. Other Circumstances (Optional): It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits. However, an applicant may choose to list constraints associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control).

' Supporting documentation is presented in Section [II.F. 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 III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 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 Rapanas 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 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 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 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.C below.

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.

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: I.

CHARACTERISTICS OF TRHiUTARY (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 Rapanor 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 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 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.

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.C below. 1.

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 can•y 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?

Explain: ~ Boxes checked below shall be supported by completing the appropriate sections in Section III below. ` 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). Supporting documentation is presented in Section [ILF. 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 III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 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 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 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 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.C below. 1.

Explain: ~ 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). Supporting documentation is presented in Section [I[.F. 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 III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 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 Rapanor 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 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 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 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.C below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: spick List Drainage area: Pick List Average annual rainfall: inches Average annual snowfall: inches (ii) Physical Characteristics: (a) Relationship with TNW: ^ Tributary flows directly into TNW. ^ Tributary flows through Piek T~ist tributaries before entering TNW. Project waters are ick ~3st river miles from TNW. Project waters are i'u~k;Lest river miles from RPW. Project waters are aerial (straight) miles from TNW. Project waters are Pick ~.ist aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Identify flow route to TNWS: Stream flows into a tributary, which flows to Lake Benson. Tributary stream order, if known: ° Note that the Instructional Guidebook contains additional information regazding swales, ditches, washes, and erosional features generally and in the acid West. s Flow route can be described by identifying, e.g., tributary a, which flows through the review azea, to flow into tributary b, which then flows into TNW. (b) General Tributarv Characteristics (check all that apply): Tributary is: ^ Natural ^ Artificial (man-made). Explain: ^ Manipulated (man-altered). Explain: Tributary properties with respect to top of bank (estimate): Average width: feet Average depth: feet Average side slopes: Eck X:ist.

(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: ~A 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.

For each wetland, specify the following: Directly abuts? (Y/M Size (in acres) Directly abuts? (Y/M Size (in acres) 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: 1. 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: 2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section III.D: 3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW.
