P.A. T.O.C. 2 ENVIRONMENTAL ASSESSMENT (EA) AND FINDING OF NO SIGNIFICANT IMPACT (FONSI) ' PLANTATION CANAL PROPOSED MAINTENANCE DREDGING PROJECT TOWN OF RIVER BEND, NORTH CAROLINA I.July 12, 1999 1.0 PROJECT DESCRIPTION ' Mid-Atlantic Associates, P.A. (formerly GulfStream Environmental, Inc.) was retained by Mr. William C. Raybon, P.E. of Raybon Engineering P.A., to perform an Environmental Assessment (EA) on the proposed Plantation Canal ' maintenance-dredging project within the Town of River Bend, North Carolina. The proposed maintenance project is classified under the North Carolina Environmental Policy Act (NCEPA), as outlined in NCAC T 15A: 01 C.0504 (4n): ' (7/31/96), as a Non-Major Management Activity. Per this designation, the "dredging of existing navigation channels and basins to originally approved ' specifications, provided that the spoil is placed in existing and approved high ground disposal areas" does not warrant the preparation of an EA. However, this EA has been commissioned to document potential environmental impacts that ' may arise during the execution of the proposed project, in an effort to mitigate these potential factors. The purpose of the EA -- as directed by NCAC T15A: 01 C.0100-.0500 (7.31.96) and included in the Guidelines for the preparation of an ' EA -- is to provide a decision making tool for state agencies in determining the potential environmental impacts of planned projects, and to make the determination of whether an Environmental Impact Statement (EIS) is necessary ' (Guidelines EA-1). The scope of work performed during this assessment has included (1) the review ' of pertinent technical documentation, (2) the review of available aerial photography, (3) the consultation of regulatory officials with the United States Fish and Wildlife Service (USFWS), the North Carolina (NC) Division of Marine ' Fisheries (DMF), the NC Division of Coastal Management (DCM), the NC Division of Water Quality (DWQ), Water Quality Section (WQS), the NC Division of Water Resources (DWR), the North Carolina Wildlife Resources ' Commission (NCWRC), and the NC Natural Heritage Program, and (4) the review of the proposed engineering design, to date. ' Mid-Atlantic has performed this assessment in accordance with the proposal entitled "Proposal/Cost to Prepare an Environmental Assessment (EA)," dated November 10, 1998, and the Guidelines for the preparation of an EA/FONSI. The ' activities performed during this study were authorized by Mr. William C. Raybon, P.E., on behalf of the Town of River Bend, in the Mid-Atlantic Proposal Acceptance Contract executed on December 10, 1998. 1 Mid-Atlantic Associates, P.A. ' Page 1 I I EA/FONSI July 12, 1999 1.1 Description of Project Area A USGS Topographic Quadrangle (7.5 Minute) depicting the site region has been provided as Figure 1, a Site Plan has been provided as Figure 2. and details of the canal system have been provided as Figures 3-5. Site photographs collected during the site reconnaissance are provided in Appendix 1. Aerial photographs of the area have been furnished in Appendix 11 for the years of 1968, 1989, and 1993. 1.1.1 Setting The Town of River Bend is located in Craven County, within the coastal plain physiographic province of North Carolina, approximately 5.0 miles west of New Bern, North Carolina (Figure 1). The corporate limits of the town are bound to the north by Highway 17; however it should be noted that the Springdale subdivision, Hidden Oaks (Extra-Territorial Jurisdiction (ETJ)), and Deerfield Phase III (ETJ), are located north of Hwy. 17 (Figure 2). The southern boundary of the town abuts the Trent River, which adjoins Plantation Canal. Plantation Canal, its branches. headbasin, and Island Lake are backwaters of the Trent River. Plantation Canal is an artificial waterway constructed in 1974, during the initial development of River Bend (Figures 3-5/Photographs 1,3,4.5,6). Dredging of the freshwater canal was performed in the location of a former creek bed adjacent to Samuel's Branch in Rocky Run, a division of Hayward Creek along the eastern boundary of the property limits (see Aerial Photographs). The original CAMA Major Permit Application was not available at the time of this report. The project included the excavation of a watercourse through wetland swamp areas, including the construction of a marina basin, main canal course, drainage/retention ponds, and secondary canals. Project excavation limits included the dredging of the marina basin, consisting of approximately 4.0 acres, and the main channel connecting to the Trent River, stretching approximately 1.0 mile (Report 5). Initial project design criteria involved the excavation of a main channel with a surface width of ±100.0 ft. and a center channel with a bottom width of ±50.0 ft., at a minimum centerline depth of 6.0 ft. below mean low water (MLW) (Report 5). Sediment accumulation and shoaling within Plantation Canal has been caused by a number of factors consisting of sedimentation, siltation, and sloughing of the unstabilized north bank (in the main channel). The canal system was originally designed to (1) provide boating/recreational access to the waterfront community of River Bend. and (2) serve as the central drainage feature for the development. Plantation Canal, the associated secondary canals, and the retention Mid-Atlantic EANFONSI .July 12, 1999 ' ponds/drainage ditches throughout the town are interconnected, and function to facilitate proper drainage regimes, as intended by the ' developer (Photographs 2,5,6,7). The canal acts as the receiving body for directed flow and sheet flow throughout the town limits. The canal's utility as a drainage feature is absolutely necessary (Photograph 5). ' Circulation within the canal system is driven by precipitation, runoff, and wind tides. Lunar tidal influence is minimal and saline intrusion into the canal system is limited to the confluence point of Plantation Canal and the ' Trent River. 1.1.2 North Carolina Division of Water Quality, Water Quality Section ' Surface Freshwater Classifications Used in North Carolina - Adjacent Waterbodies ' The NC DWQ, WQS has developed water quality classifications for surface freshwaters in North Carolina. These surface water classifications "are designations applied to surface water bodies, such as streams, rivers, ' and lakes, which define the best uses to be protected within these waters and carry out with them an associated set of water quality standards to protect those uses" (Classifications 1). The water bodies located adjacent ' to the Town of River Bend carry the following classifications (Classifications and NCAC T15A: 02B .0100): Trent River (SB Sw NSW)-- The portion of the Trent River that runs adjacent to River Bend is located in the NEUI 1 sub-basin is indicated by index number 27-101-(31) and is located on map number G30S W5. This run of the Trent is classified as SB (saltwaters protected for primary recreation which includes swimming on a frequent or organized basis and all SC uses, including secondary recreation, fishing, aquatic life including propagation and survival, and wildlife), with supplemental classifications of Sw (swamp waters which have low velocities and other natural characteristics which are different from adjacent streams) and NSW (nutrient sensitive waters subject to growths of microscopic or macroscopic vegetation requiring limitations on nutrient inputs). • Rocky Run (C Sw NSW) - This tributary of Hayward Creek is located in the NEU 11 sub-basin, is indicated by index number 27-101- 35-1, and is located on map number G30S W6. Rocky Run is classified as C (freshwaters protected for secondary recreation, fishing, aquatic life including propagation and survival, and wildlife), with supplemental classifications of Sw (swamp waters) and NSW (nutrient sensitive waters). • Hayward Creek (C Sw NSW) - This branch of Hayward Creek is located in the NEU 11 sub-basin, is indicated by index number 27- 10 1 - Mid-Atlaotic Associates, P.A. Pate 3 EANONSI July 12,1999 ' 35, and is located on map number G30SW3. Hayward Creek is classified as C (freshwaters protected for secondary recreation, fishing, aquatic life including propagation and survival, and wildlife), with supplemental classifications of Sw (swamp waters) and NSW (nutrient sensitive waters). ' • Plantation Canal - Plantation Canal is not listed within the classification schedule. This manmade canal is therefore incorporated ' by reference to the adjacent stretch of the Trent River (SB Sw NSW). • Samuel's Branch - Samuel's Branch is not listed within the classification schedule. This tributary is therefore incorporated by reference because it is a branch of Hayward Creek and Rocky Run (C Sw NSW). ' 1.2 Description of Proposed Action ' The objective of this project is to perform routine maintenance dredging on Plantation Canal to return the watercourse to its original permitted elevation and condition. Because this project involves the maintenance of a pre-existing channel, and does not entail the expansion of the waterway, or dredging in areas outside the original footprint of the canal system, it qualifies as a Non-Major Activity with respect to the North Carolina Environmental Policy Act. This classification is an exemption from the requirement to prepare environmental documentation, such as this EA. ' As proposed, this maintenance project will involve the removal of approximately 42,000 yds3 of material, consisting of some surficial silt material, but mostly comprised of sand throughout the entire length of ' Plantation Canal and the secondary canals. Dredging will be effected with a hydraulic dredge and decanter/staging barge. Dredge spoils will be placed in one of three upland disposal areas designated for use in this ' project (Photographs 8-10). The location of the three proposed disposal areas is shown. on Figure 2. Maintenance dredging will be performed on the central navigation channel only, and will not cover the entire canal width. Current profile elevations are noted in the hydrographic survey generated by Raybon Engineering, P.A. The design standard for the ' channel will provide a channel width of approximately 30.0-ft., and a minimum centerline channel depth of approximately 6.0 ft. below MLW. ' The Town of River Bend has been awarded $292,000 in financial assistance to subsidize this project. The project has been endorsed by NCDENR based on its merit for improvements to existing water quality within the system. Per the 9.22.97 correspondence from Wayne McDevitt, Secretary of the Department of the Environment and Natural Resources (NCDENR), the grant has been approved on behalf of the DWR and ' Mid-Atlantic Associates, P.A. Page 4 Ci EA/FONSI July 12, 1999 NCDENR to improve navigation, facilitate stormwater drainage, and benefit fish habitats (Appendix III). 1.3 Benefits of Proposed Project The maintenance dredging of Plantation Canal and the associated secondary canals will provide multiple benefits to every medium affected by the project, whether water quality, fish, wildlife, or human interests. As noted above in Section 1.2, a financial assistance package has been approved for this maintenance project by the NCDENR, because the "removal of sediment and shoals from the Plantation Canal will improve navigation for the citizens of River Bend and the boating public," and "will also improve fish habitat and storm water drainage" (McDevitt). In addition, representatives from the North Carolina Division of Coastal Management (Mr. Scott Jones) have expressed their support for this project, due to increased flushing and an improvement in water quality resulting in decreased aquatic vegetation growth (green algae and blue- green algae).

Mid-Atlantic Associates, P.A. Page 5 2.0 NEED FOR PROPOSED PROJECT EANONSI July 12,1999 The need for the maintenance dredging of Plantation Canal has been recognized by the citizens of River Bend, the River Bend Town Council, the Waterways Advisory Board, and the regulatory community, as documented by their support of this project. As documented above in Section 1.3, the need for this project arises from an improvement in water quality, circulation, flushing, and fish habitats, the reduction of aquatic plant growth, the benefits to the local economy and land use potential, and the importance of the watercourse as the central drainage feature of the town. The River Bend community was originally developed around this navigational/drainage feature. By dredging the watercourses, the health of the entire system will be augmented. Maintenance dredging of the canal system will effectively (1) improve water quality, (2) benefit fishery habitats and spawning areas, (3) improve circulation and flushing within the canals by removing accumulated sediments, (4) reduce the effects of eutrophication, i.e. aquatic vegetation propagation, (5) maintain the canal as the central drainage feature within the town, and (6) provide suitable fill materials to enhance public-use areas. 3.0 ALTERNATIVE ANALYSIS In considering the maintenance dredging project, as proposed, one other alternative is also available - a no action alternative. Analysis of this proposed alternative is provided hereafter in Section 3.1. 3.1 No Action ' The option proposed as "No Action" will facilitate continual degradation of the environmental condition of the canal system. The eutrophication of receiving waters will continue to foster aquatic vegetation growth with the ' introduction of nitrates and phosphates, as noted in the study entitled "Water Quality Monitoring of the Waterways of River Bend, NC May 1994 to April 1995," dated April 12, 1995. This perpetuation of green/blue-green algae in the spring and summer months will ultimately cause a degradation of water quality, resulting in low dissolved oxygen content, and conditions possibly leading to a fish-kill. Without increased circulation and flushing of the watercourse, combined with continual sedimentation, shoaling, and nutrient loading, the Plantation Canal system may ultimately become a tributary unable to support normal aquatic life ' functions.

Nitrogen fertilizes algae and make it grow. Algae uses oxygen for respiration (at night) and decay. Detail 1 Source: Neuse River Riparian Area Rule http://h2o.etir, state. nc.us/nps/cheat-s3.htm Additionally, the "No Action" alternative will prevent free flow exchange between the Trent River and Plantation Canal. This prohibition will also result in water quality degradation, which will adversely impact anadromous fishery spawning (Bream, Striper, Losid, Blue Back Herring, and American Shad) and habitat areas (Striped Bass). ' In summary, the rate of degradation to the canal eco-system is anticipated to occur exponentially. Eutrophication and water quality degradation will be exacerbated without improvements to hydraulic flow regime of the ' system. The "No Action" alternative is not a viable solution for improving the current declining quality of surface water in the canal. ' 3.2 Option as Proposed By performing the maintenance-dredging project, as proposed, ' improvements to water quality, fishery habitats, and spawning areas will be realized. Additionally, the canal system will remain open for navigable ' use and recreation by the public. Further, the maintenance project will facilitate the improvement of the canal as a drainage feature, as it was originally designed. The multiple benefits of this project, as discussed ' above in Sections 1.0 and 1.2, will all benefit property values throughout the Town of River Bend, as they should appreciate as a function of the canal improvement. 1 ' Mid-Atlantic Associates, P.A. Page 7 EANONSI July 12,1999 ' 4.0 ENVIRONMENTAL CONSEQUENCES ' 4.1 Changes in Land Use ' Changes in land use will result in the preparation of the dredge spoil upland disposal/staging areas. These areas will be cleared and diked to accommodate all materials generated during the project. Ultimately, the dredged materials will be relocated to provide fill in low-lying/frequently ' flooded areas. This measure will provide beneficial use of the material, and will improve these public-use areas. Following the removal of the dredged sediments from the disposal areas, the impoundments will be ' restored to their original conditions, and will be seeded to prevent erosion of surficial sediments. ' Additionally, any disturbance caused to the canal bank during dredging o erations will be restored before roject com letion p p p . ' 4.2 Wetlands According to. the proposed project engineering design, no impacts to ' wetlands will occur. Dredged materials will be placed in existing upland disposal areas only. No dredging, filling, or alteration of wetlands will occur during the project, as only the original canal will be maintained. ' One of the disposal areas selected will however, abut a USACOE Section 404 wetlands area. The wetlands in this locale have been properly ' delineated and will not be impacted by dike construction. The location of this wetland area is shown in Appendix IV. ' 4.3 Prime or Unique Agricultural Lands No prime or unique agricultural lands were identified as part of the scope ' of this project. 4.4 Public Lands ' Maintenance dredging of the canal system within River Bend is a r?pscsen significant improvement to the public trust waters constituting the channel. ' No other public lands - national forests, seashores, corridors, easements, or reserves - will be impacted as a result of this project. ' 4.5 Scenic and Recreational Areas ' As discussed previously in Sections 1.3 and 4.1, recreational areas will benefit from this project. First, several areas of low elevation, which are frequently flooded, will be provided with suitable sand fill from the ' Mid-Atlantic Associates, P.A.

Additionally, by ring .water quality and fishery will be augmented. Dredging lth and recreational viability of 4.6 Areas of Archaeological or Historical Value No areas of archaeological or historical value have been identified during this assessment. Additional research will be performed to confirm the cultural or archaeological significance of the proposed disposal sites, for inclusion in the final document. 4.7 Air Quality Potential impacts to air quality, as a result of the project operations, are not anticipated. No emissions of primary or secondary sources are proposed. Some sediments may become airborne following drying in the upland disposal impoundments. Impacts as a result of these effects should be mitigated by the design height of the impoundment structures. 4.8 Groundwater Quality No impacts to groundwater quality were identified during this assessment. 4.9 Noise Levels Noise levels, both sub-aqueous and ambient, may exceed normal background levels during the execution of the project. This is primarily due to noise caused by the mechanical dredge apparatus. These levels are not expected to pose adverse effects to the surrounding environments and are characteristic of routine dredging projects conducted throughout the region. 4.10 Water Supplies r No direct impacts to water supplies are expected to occur as a result of this project. The NC Division of Water Resources has expressed their approval of the project, as resulted in the approval of the financial assistance package discussed in Section 1.2. ' Mid-Atlantic Associates, P.A. Page 9 C I I EA/FONSI July 12,1999 4.11 Shellfish/Fish Habitats/Wildlife Habitats - Endangered/Threatened Species (NC Wildlife Resources Commission, NC Division of Marine Fisheries, NC Natural Heritage Commission, US Fish and Wildlife Service) • According to Brad Hammers, Biologist with the North Carolina Wildlife Resources Commission, potential impacts of the maintenance-dredging project stem from sedimentation, impacts to fishery habitats, and possible interruption of normal spawning cycles. A letter from Mr. Hammers and the NC Wildlife Resources Commission is included in Appendix V. Throughout the course of discussions with Mr. Hammers, and included in the letter from him, Mr. Hammers noted that the Striped Bass Fishery utilizes portions of the Trent River adjacent to Plantation Canal for winter habitat; however he was unaware of their use of Plantation Canal as such, but indicated that it is a possibility. Additionally, Mr. Hammers indicated that the dredging should be performed in the winter months to avoid impacts to Bream and Striped Bass spawning cycles in the vicinity. These spawning periods occur during a moratorium from April 1- September 30. Additionally, according to Mr. Hammers, "fisheries resources in this area or adjacent areas provide a very valuable recreational fishery and include striped bass, largemouth bass, bluegill, redear sunfish, and pumpkinseed" (Letter dated February 5, 1999). • Mr. Jim Francesconi, Fisheries Biologist with the NC Division of Marine Fisheries, indicated that Plantation Canal area was not under the jurisdiction of the agency. Mr. Francesconi stated, however, that this region was not a primary nursery area, but it is a spawning area for Stripers, Losids, Blue Back Herring, and American Shad. • According to Ms. Susan Giles, Information Specialist with the North Carolina Natural Heritage Program, "The NC Natural Heritage Program does not have records of high quality natural communities, rare species, or Significant Natural Heritage Areas at or within a 1.0 mile radius of the site of the proposed maintenance dredging of the Plantation Canal, Town of River Bend, NC" (letter 1.14.99). The letter documenting these findings has been included in Appendix VI. • According to Mr. Ken Graham, Biologist with the US Fish and Wildlife Service, endangered terrestrial species have been highlighted and located in Craven County by the Department of the Interior, however, this has not been done for aquatic species. Mr. Graham referred the inquiry to the NC Natural Heritage Program, as referenced above. Mr. Graham noted the sighting of one Manatee and one Leatherback Sea Turtle, both discovered at the mouth of the Trent River within the last ten years. No sightings have been confirmed in the area of the Trent adjacent to Plantation Canal or within the canal. Mr. Graham stated that the likelihood of encountering either of these species within Plantation Canal was "very low." I Mid-Atlantic Associates, P.A. Page 10 EA/FONSI July 12, 1999 i A letter from the U.S. Fish and Wildlife Service has been included in Appendix VII. ' 4.12 Introduction of Toxic Substances ' The likelihood of the introduction of toxic substances during the dredging project is very low, and is limited to the potential release of liquid petroleum hydrocarbons associated with refueling and normal operation ' procedures of the dredge. A characterization of sediments quality was performed in March of 1999. ' Sediment samples were collected by Eastern Environmental in eleven locations through the entire length of the canal. Samples were analyzed for Oil & Grease as well as the RCRA primary metals. Oil & Grease ' concentrations were detected above the regulatory limit of 250 mg/kg in six of the 11 stations sampled. The firm conducting the sampling has attributed this occurrence to naturally occurring organics. None of the ' RCRA metals analyzed exceeded regulatory limits. A copy of the sampling report is contained in Appendix VIII. ' 4.13 Eutrophication of Receiving Waters The eutrophication of receiving waters is already a current phenomenon within the Plantation Canal system. Mitigative measures to address this problem are further detailed in Section 5.0. Additional nutrient loading is not expected to occur as a result of this project. ' 4.14 Hydraulics ' Maintenance dredging of the channel will increase the cross-sectional area of the channel, thus increasing circulation and flushing. This improvement between the exchange of waters between the Trent River and Plantation Canal, however, will not result in increased water levels within the canal during flood stages or storm events. Dredging should actually result in the displacement of floodwaters during these episodes. 4.15 Sediment Sampling ' Sampling of proposed dredged sediments has been performed by Eastern Environmental. A report documenting the results of the sampling event has been included in Appendix VIII. As noted in the report, concentrations of TCLP RCRA Metals were not detected above the regulatory action levels in any of the 11 samples. However, ' concentrations of Oil & Grease were detected above regulatory action levels in six of the 11 samples. Eastern Environmental attributed the presence of these compounds to "Naturally occurring oils from both macro ' Mid-Atlandc Associates, P.A. Page 11 i ' EA/FONSI July 12,1999 and micro plant and animal remains" found in these "highly organic bottom ...swampy sediments" (March 16, 1999). ' 4.16 Water Quality Sampling No water quality sampling has been performed as of the date of this report. ' 5.0 MITIGATIVE MEASURES The Town of River Bend was designed around an interconnected series of ' drainage ditches, retention ponds, and finger canals, all of which flow to Plantation Canal and eventually to the Trent River. River Bend has, and continues to move forward in a pro-active manner to address sensitive ' environmental issues within and around the Plantation Canal system. Presently, the town has implemented measures to mitigate the effects of sediment influx, nutrient loading (eutrophication), and the introduction of toxic substances, via ' stormwater runoff, into the receiving waters of the canal system and ultimately the Trent and Neuse Rivers. The Town has been awarded a financial assistance package for the .implementation of a Wetlands Enhancement Program from the ' NC Water Resources Planning Section. This grant was provided to execute a water resources development project, as outlined further below. ' To date, the Town of River Bend has installed aerating fountains in the retention ponds to increase circulation, and has also implemented a Wetlands Enhancement Program in two areas (Photographs 2 and 7). First as detailed in Photograph 2, the Enhancement Program involved the construction of wetlands in one of the retention ponds (adjacent to Hwy. 17). Since this pond is located near the head of the drainage system, this vegetative filter serves to reduce sediment, nutrient, and ' toxic material loading from the area around Highway 17, and adjacent neighborhoods, to the receiving waters. Vegetative swales were also constructed around the perimeter of this pond to serve as filters for surficial runoff. Second, a ' series of vegetative filters/ wetlands will be constructed within a drainage ditch that empties into the pond/canal system (Photograph 7). This ditch is located at a topographic low point along Plantation Drive, which acts as the receiving drain for an upgradient neighborhood. With respect to future mitigative measures, the Town of River Bend proposes to ' first ; develop a "Nutrient Management Plan (NMP)" in accordance with the requirements outlined in the Neuse Nutrient Sensitive Waters Management Strategy, adopted by the North Carolina Environmental Management Commission ' on December 11, 1997. The objective of this NMP would be to reduce nutrient loading (eutrophication), promote denitrification, prevent sedimentation, and increase vegetative buffers within riparian corridors. Detail 2 outlines the ' composition of vegetative riparian corridors below. Secondly, as a proposed mitigative measure, River Bend will schedule all dredging activities around Mid-Atlantic Associates, P.A. Page 12 EANONSI July 12,1999 spawning moratoriums established by the relevant agencies, as discussed in Section 4.11. A third mitigative measure to promote flushing and prevent stagnant conditions would involve dredging the mouth of the canal as the deepest point, with a general decrease in elevation to the end of the project. Additionally, a sediment or silt curtain will be emplaced at the mouth of the canal to prevent potential sedimentation in the receiving waters of the Trent River. And lastly, to minimize potential effects from increased upland drainage, properly engineered and constructed upland disposal areas will be utilized. ?6 ' { ? ? ? ty c ? ? ?

Mill 6.0 FINDING OF NO SIGNIFICANT IMPACT (FONSI) As described in the Environmental Assessment above, the Town of River Bend proposes to remove approximately 42,000 yds3 of a sand/silt material during the routine maintenance dredging of the Plantation Canal system. All dredged materials generated during this project will be placed in existing upland disposal areas. The activities proposed herein are classified under the North Carolina Environmental Policy Act (NCEPA), as outlined in NCAC T15A: 01C.0504 (4n): (7/31/96), as a Non-Major Management Activity. Per this designation, the "dredging of existing navigation channels and basins to originally approved specifications, provided that the spoil is placed in existing and approved high ground disposal areas" does not warrant the preparation of an EA. This EA has been commissioned by the Town of River Bend to identify potential environmental impacts that may arise during the execution of the proposed project, in an effort to mitigate any potential adverse elements. I Mid-Atlantic Associates, P.A. Page 13 I EA/FONSI July 12, 1999 I This project will not have significant adverse impacts on the state or quality of the surrounding environment because the canal will only be maintained to its ' originally permitted condition. No expansion of the canal or extension of the original footprint will be effected. This project will actually serve to benefit the condition of the watercourse in its entirety through: I • improvement of water quality • improvement of fishery habitats I • improvement of flushing/circulation • establishment of a Nutrient Management Plan to implement riparian corridor buffers, reduce nitrate/phosphate loading, promote ' denitrification, and prevent sedimentation • improvement of navigation/recreation potential • reduce oxygen-depleting algae ' River Bend has begun implementing a pro-active campaign to mitigate adverse environmental impacts as they relate to runoff, eutrophication, sedimentation, and ' the vitality of the canal. The Town of River Bend has already been awarded a financial assistance ' package, consisting of $292,000, to assist in the performance of this project. As noted in the approval letter from Wayne McDevitt, Secretary of the NCDENR, dated 9.22.97, "the removal of shoals from the Plantation Canal will improve ' navigation for the citizens of River Bend and the boating public" and "will also improve fish habitat and storm water drainage." This support emphasizes the approval of this project by the Department of Environment and Natural ' Resources, the Secretary, and the Division of Water Resources. ' No Environmental Impact Statement is anticipated for this project. This Finding of No Significant Impact (FONSI) completes the environmental record for presentation to the State Clearinghouse.

Fullwood, Executive Director ' MEMORANDUM February 5, 1999 ' FROM: Brad E. i lanuners 41, Division of Inland Fisherics ' TO: Jon Jester Gulfstream Environmental ' SUBJECT: Scoping request for information to be used in preparing an Environmental Assessment (EA) for Maintenance Dredging of Riverbend Canal in Craven ' Countv. North Carolina. The following information is pro% ided as per our discussion on 1/14/99 concerning the ' maintenance dredging project in the canal connecting to the Trent River in the Riverbend community. Some potential concerns rewarding the project include excessive sedimentation/turbidity and hottom disturbance during dredging activities. Elevated turbidity ' could reduce water quality in this area and stress aquatic organisms. Excessive turbidity is particularly damaging to eg and larval lifi: stages of aquatic organisms. Fisheries resources in this area or adjacent areas provide a verb %aluahle recreational fishery and include striped bass, ' largemouth bass. hluegill, redear sunfish. anti pumpkinseed. Measures to avoid or minimize impacts to these resources should include restricting dredging activities during warmer summer months (i.e. April i - September ,0) and localizing turbidity by employing a sediment curtain at the mouth of the canal during dredging. -Also. a stormwater management plan should be implemented to control nutrients and other pollutants that negatively impact aquatic resources in ' the canal. In addition, we are providing the following standardized letter. Although some of the ' information requests and comments ma% not he applicable to certain projects, these guidelines should facilitate preparation of fisheries and wildlife impact assessments. Our ability to evaluate project impacts and provide heneficial recommendations when reviewing environmental t documents will be enhanced if consultants. project sponsors, or permit applicants provide the following information. 1 1. Complete descriptions ol'\viIdlil'k!. fisheries, and wetland resources within, adjacent to, or utilizing the proposed project construction area including a listing of species designated as Iedcrally or state endangered, threatened, or special concern. When practicable, potential borrow areas to he used for project construction and discharge areas should be included in the invcntorics. i\ listing ofdesignated animal and plant species can be developed through consultation with: N.C. Natural I Ieritage Program P.O. Box 27087 Raleigh, N.C. 17611 (919)733-7795 and, N.C.D.A. Plant Conservation Program P.O. Box 27047 Raleigh, N.C. 27611 (919)7')3-',0 10 ' ?. Project map identifying wetland acreage impacted by the project. Wetland acreage should include all pro.iect related .a-cas that may undergo hydrologic change as a result of ditching, other drainage. or tilling for project construction. Wetland identification may be ' accomplished through coordination with the U.S. Army Corps of Engineers (COE). If the COE is not consulted. the person delineating wetlands should be identified and criteria listed. 3. Description of anv streams or \cctlands affected by the project. The need for channelizing or relocatlnul portion; )I streams and the extent of such activities should be noted. Any water withdrawals from 11-01.1ndwater or surface water sources should also be well described. In addition. wetland acreage impacted by alternative project designs should be provided. Finally, for prOiccts involving the discharge of wastewater, potential impacts to streams and wetlands >hOUld be thoroughly described, whether wastes are directly dischgruod tr. surface wa. rs „ !and applied. Adequate buffers should be maintained bemeen all land application areas and wetlands or streams. 4. Description of project site and non-wetland vegetative communities. 5. The extent of wildlife habitat iragmentation in uplands and wetlands and impacts associated with fragmentation. 6. Mitigation for avoiding, minimiAna, or compensating for direct and indirect habitat loss and degradation in quantitative terms. 1 7. A discussion of the cunlul IM e impacts of secondary development facilitated by the proposed faciIIth inlpro\enlentS. tillch discussion should weigh the economic benefits of ' the project against the costs ofassociated environmental degradation. 8. Ifenvironmcntal docunrents are required, a list ofpreparers and respective areas of ' expertise, including professional qu:llifications, should be included. Measures to avoid or minimize impacts to sensitive resources, including wetlands, should ' be implemented throughout Iacility p1a1111111e and construction. Where impacts to wetlands are unavoidable, the N.C. Wildlife Resources c '0mlrlission %?ill recommend mitigation for the losses. Professional wildlife and fisheries hiolouists should be consulted if aquatic, wetland, or terrestrial ' habitats are affected by this type of development.

PIAI uKAL nr U ALYL rxvtzKAM UMINTY brhL;Mb LlbT LUVLK SHEET e county species list from the NC Natural Heritage Program is a listing of the elements (rare species, natural communities, and ecial animal habitats) known to occur in a county. The information on this printout is compiled from a variety of sources, including field surveys, museums and herbaria, literature, and personal communications. The Heritage Program's Biological and conservation Database (BCD) is dynamic, with new records being added and old records being revised as new information is ceived. The BCD was developed and is maintained using methodology developed by The Nature Conservancy. The enclosed list cannot be considered a definitive record of natural heritage elements, and it should not be considered a substitute for field surveys. ['he-i this information is used in anv document, we request that the printout date be given and that the NC Natural Heritage ogram be credited. s cover sheet explains the four columns of status codes that are given on the right-hand side of the county list printout. STATE STATUS ODE STATUS Endangered T Threatened I C Special Concern Candidate CODE STATUS P Proposed (E, T, or C) SR Significantly Rare EX Extirpated Wan: statuses are determined by the Plant Conservation Program (NC Department of Agriculture) and the Natural Henmee roz'am (NC Department of Environment and Natural Resources). E, T, and SC species are protected by state law (Plant Protection and Conservation Act, 1979). C and SR designations indicate rarity and the need for population monitoring and I orservation action. Ammal statuses that indicate state protection (E, T, and SC) are published in Endangered Wildlife of Yorrh Carolina, March 16, 99:, Nongame and Endangered Wildlife Program (NC Department of Environment and Natural Resources). SR and EX statuses Ire Natural Heritage Program designations. SR indicates rarity and the need for population monitoring and conservation action. FEDERAL STATUS is status is designated by the US Fish and Wildlife Service. Federally listed Endangered and Threatened species are protected under the provisions of the Endangered Species Act of 1973, as amended through the 100th Congress. Unless otherwise noted. Flniiions are taken from the Federal Re?isrer, Vol. 56, No. 325, November 21, 1991 (50 CFR Part 17). CODE STATUS DEFINITION Endangered A taxon "in danger of extinction throughout all of a significant portion of its range." Threatened A taxon "likely to become an endangered species within the foreseeable future throughout all of a significant portion of its range." _ Proposed A taxon proposed for official listing as endangered or threatened. Candidate A taxon under consideration for which there is sufficient information to support listing. This categor;.- was formerly designated as a Candidate 1 (C1) species. SC Federal "Species of Concern" (also called "Species at Risk"). Formerlv defined as a [axon under consideration for which there is insufficient information to support listing; formerly designated as a Candidate ' (C2) species. Currently, the US Fish and Wildlife Service does not recognize this as an official designation. (S, A) Threatened due to Similarity of Appearance. Species with this designation are not considered biologically endangered or threatened and are listed for trade purposes. [The American Alligator has this designation ' due to similarity of appearance to other rare crocodilians. The Bog Turtle (southern population) has this designation due to similarity of appearance to Bog Turtles in the threatened northern population.] Please note that the US Fish and Wildlife Service no longer recognizes the following categories: IA Candidate 3A A taxon formerly under consideration for listing, but for which there is "persuasive evidence of extinction." 3B Candidate 3B A taxon formerly under consideration for listing, but which current taxonomic understanding does not support as a distinct entity meeting the Endangered Species Act's definition of "species." 'C Candidate 3C A taxon formerly under consideration for listing, but which has been "proven to be more abundant or widespread than previously believed and/or [which is] not subject to any identifiable threat." GLOBAL AND STATE RANKS These ranks are determined by The Nature Conservancy's system of measuring rarity and threat status. "Global" refers to worldwide ranks and "State" to statewide ranks. STATE RANK DEFINITIONS Sl Critically imperiled in North Carolina because of extreme rarity or otherwise very vulnerable to extirpation in the state. S" Imperiled in North Carolina because of rarity or otherwise vulnerable to extirpation in the state. S3 Rare or uncommon in North Carolina. S» Apparently secure in North Carolina, with many occurrences. S5 Demonstrably secure in North Carolina and essentially ineradicable under present conditions. SA Accidental or casual; one to several records for North Carolina, but the state is outside the normal range of the species. SH Of historical occurrence in North Carolina, perhaps not having been verified in the past 25 years, and suspected to be still extant in the state. SR Reported from North Carolina, but without persuasive documentation for either accepting or rejecting the report SX Believed to be extirpated from North Carolina. S: Possibly in peril in North Carolina, but status uncertain; more information is needed. S^ Unranked, or rank uncertain. B Rank: of breeding population in the state. Used for migratory species only. Rank of non-breeding population in the state. Used for migratory species only. _Z_ Population is not of significant conservation concern; applies to transitory, migratory species. GLOBAL RANK DEFINITIONS G1 Critically imperiled globally because of extreme rarity or otherwise very vulnerable to extinction throughout its range. GZ Imperiled globally because of rarity or otherwise vulnerable to extinction throughout its range. G3 Either very rare and local throughout its range, or found locally in a restricted area. G» Apparently secure globally, although it may be quite rare in parts of its range (especially at the periphery). G5 Demonstrably secure globally, although it may be quite rare in parts of its range (especially at the periphery). GH Of historical occurrence throughout its range. GX Believed to be extinct throughout its range. Gt; Possibly in peril, but status uncertain; more information is needed. G` Unranked, or rank uncertain. G _Q Of questionable taxonomic status. T_ Status of subspecies or variety; the G rank refers to the species as a whole. ADDITIONAL DEFINITIONS Elements following county names marked with one or two asterisks indicate obscure or historic records. Obscure record: the date the element was last observed in the county is uncertain. '• Historic record: the element was last observed in the county more than 50 years ago.

Eastern Environmental recently collected sediment samples from along River Bend's Channel Run Canal. The samples were collected at approximately 750 feet intervals. Sediment cores ranging between 12 and 18 inches were recovered, placed in sterile jars on ice for delivery to the analyzing laboratory. The samples were analyzed by Method 9071A for Oil & Grease and TCLP Extraction, Method SW846 1311, RCRA Metals. The analysis results indicate metal concentrations are significantly below regulatory action levels. The Oil & Grease concentrations are above regulatory limits in 6 of the sediment samples. These results are not surprising for highly organic bottom or swampy sediments. Naturally occurring oils from both macro and micro plant and animal remains can account for the elevated concentrations found in the samples. A correlation in the analysis and the sediment descriptions is apparent. The mucky, highly organic sediment samples with obvious plant debris show the highest Oil & Grease concentrations. Sandier, less organic samples have lower Oil & Grease concentrations. Please see the following attachments: Figure 1 Site location & Topographic Map Figure 2 Bottom Sample Collection Locations (except Island Creek) Figure 3 Sediment Core Descriptions Table 1 Summary of Sediment Sample Laboratory Analysis Laboratory Reports and Chain of Custody. If you have questions please call (252) 637-7884. Thank you for allowing Eastern Environmental to be of service. Sincerel F.X.
