Post Office Box 1890 Wilmington, NC 28402-1890?? f Dear Mr. McLendon: SUBJECT: New Hanover County, Bridge on US 17 Wilmington Bypass over the Northeast Cape Fear River, TIP No. R-2633CA, State Project 8.U250901 The N.C. Department of Transportation (NCDOT) proposed in its January 7, 1998 application to construct the Wilmington Bypass from US Route 421 (US 421) to approximately 5,800 feet east of Interstate 40 (I-40). The NCDOT's Soils and Foundation Design Section proposes to conduct a foundation loadtest on R-2633CA. The foundation loadtest will occur on Rat Island and in the east channel of the Northeast Cape Fear River. The loadtest will provide information on the existing subsurface conditions at the site in order to design the most economical bridge and uncover any potential construction problems associated with the site and its geology. The foundation loadtest plan consists of three elements: geotechnical tests and tests performed at Test Areas 1 and 2. Geotechnical tests involve SPT borings and CPT, dilatometer, and vane shear tests. Test Areas 1 and 2 include lateral statnamic, Osterberg Cell, and lateral static tests. Specific activities conducted during the proposed work include drilling drilled piers with bentonite slurry; constructing a reinforced concrete cap; driving, extracting, and re-driving steel piles; and advancing and extracting pre-stressed concrete (PSC) piles. Please see the enclosed foundation loadtest plan for more details on the type of work proposed. The foundation loadtest impacts 0.002 acres of waters of the United States. Measures taken to minimize the impacts include performing construction from barges and temporary platforms, accessing the site via water, demolishing all aboveground structures, and the absence of dredging activities. The NCDOT hereby applies for a Nationwide 6 permit for the proposed foundation loadtest. If you have any questions, please feel free to contact Gordon Cashin at 919- 733-7844 extension 278.

Bowers, P.E., Division 3 Engineer Ms. Leigh Lane, Project Planning Engineer FOUNDATION LOADTEST PLAN R-2633CA BRIDGE OVER NE CAPE FEAR RIVER US 17 WILMINGTON BYPASS NEW HANOVER COUNTY Primary Goals 1. To develop unit tip bearing and skin friction values for use in design of the drilled shafts for axial capacity. 2. To develop lateral capacities for use in the design of the drilled shafts for ship impact in the East Channel. 3. To develop lateral capacities for the alluvial soils and muck for the design of the approach span structures. 4. Learn about potential construction problems associated with this specific site and geology. Significant Cost Saving Areas: 1. Primarily, expect a reduction in drilled shaft lengths due to increased axial capacities and a reduced factor of safety (increased level of confidence). A reduction in shaft diameters may also be possible depending on drilled shaft lateral capacities. 2. Possibly, expect to utilize pre-stressed concrete (PSC) piles for the approach span structures as opposed to drilled shafts. This will not only depend upon the loadtest results but also upon scour elevations. 3. Also, expect to reduce potential for claims and costs associated with construction of the foundations. Geotechnical Testing Sequence and Description of Tests- 1. SPT borings at each NCHRP Group location, drilled shafts location, PSC piles location. 2. CPT testing with pressuremeter at each NCHRP Group location and the PSC piles location. 3. Dilatometer testing at each NCHRP Group location and the PSC piles location. 4. Vane shear testing on Rat Island. Test Area 1 Sequence and Description of Tests- 1. Lateral statnamic test on NCHRP Group (approximately 80,000 lb. test) on Rat Island to test muck. 2. Series of Osterberg Cell tests on the two 84" drilled shafts without the cap to test axial capacities. One shaft would tip in hard clay and would contain two 3000 ton cells (one at the bottom and one in the dense sand). The other shaft would tip in dense sand and contain one 3000 ton cell at the bottom. 3. Lateral static test on NCHRP Group on Rat Island by pulling drilled shafts and group together to test muck. 4. Lateral static test on NCHRP single piles by pushing apart for comparison to the group. 5. Lateral statnamic test on the two 84" drilled shafts with the cap (approximately 120,000 lb. test) to test lateral capacities of the dense sand (Pedee Formation). Test Area 2 Sequence and Description of Tests- l. Driving, restriking and PDA measurements on both the 30" PSC square pile with a steel H-pile stinger and a 36" PSC cylinder pile. Pile lengths would range from 70 to 110 feet. Hammer energies required are expected to range from 120 to 160 ft-kips. Jetting and drilling during driving would be expected in order to advance the cylinder pile as far as possible into the Pedee formation. The 30" PSC pile would be pulled after driving to observe the condition of the pile. 2. Lateral static test on the PSC piles by pushing them apart and using NCDOT frame to test loose alluvial soils. 3. Lateral statnamic test on NCHRP Group (approximately 80.000 lb. test) to test loose alluvial soils. 4. Lateral static test on NCHRP single piles by pushing apart for comparison to the group. Additional Comments and Details 1. Test Area 2 may be moved to deeper water if during geotechnical testing phase it is found that the proposed location has shallower than expected water. 2. We expect to have 5 barges and 2 cranes to perform this construction. 3. The drilled shafts and the concrete piles (if they can not be removed) will be left in place for demolition during the actual bridge construction. 4. Bentonite slurry will be used during the construction of the drilled shafts. All applicable permits will be obtained by the contractor for the slurry use prior to beginning construction. 5. A temporary work platform will be constructed on the banks of Rat Island in order to perform the lateral statnamic on the NCHRP Group in Test Area 1. All other work will be performed from barges. Site access will be by water from either down or up river. Item 12 - Description of proposed work. Foundation Loadtest Plan will include the following- 1. Drilling 2 2.13 m diameter drilled piers. The drilled piers will be drilled with bentonite slurry and all cuttings, as well as the slurry, will be disposed of off site. Fresh water for the bentonite slurry will be drawn from either a well onsite or piped in from off site. 2.13 in diameter steel casing will be used during drilling and remain in place during testing. The steel casing will extend from the top of the each pier to elevation -11 m. 2. Constructing a reinforced concrete cap. The bottom of the cap will be at approximately elevation 0 m and the top of the cap will be at approximately elevation 5 m. According to the US Army Corps of Engineers' control tide station located in Wilmington, NC, the mean high water elevation for the NE Cape Fear River is .85 m. The cap and the drilled piers will be demolished and removed down to the mudline by blasting after completion of testing. 3. 8 .27 m diameter steel piles will be driven, extracted and driven again in two different locations. 4 other .27 m diameter steel piles will be driven, extracted and redriven in three different locations. In some cases, the steel piles may be vibrated in. All the steel piles will be extracted and removed from the site after completion of testing. 4. One .76 m square pre-stressed concrete pile and one .91 in pre-stressed concrete cylinder pile will be driven. Methods to advance the piles to the required depth may include jetting while driving, pre-jetting and augering while driving. The square pile will have a steel pile stinger on the end approximately 3.5 meters in length. The square pile will be extracted and removed from the site after completion of testing. The cylinder pile will be demolished and removed by blasting or cutting down to the mudline after completion of testing. i A2? r'??

Wilmington Bypass Brunswick and New Hanover Counties DATE: March 25, 1991 Douglas G. Lewis Director Planning and Assessment The Department of Environment, Health, and Natural Resources has reviewed the Department of Transportation's (DOT) scoping notice to construct the Wilmington Bypass in Brunswick and New Hanover Counties. The information that was circulated for review was not sufficient to evaluate potential environmental impacts of this project. However, our review efforts did raise a number of specific issues that will need to be fully addressed in the proposed EIS. In reviewing our comments it is evident that DOT's preliminary selection of bypass corridors will have impacts of the environment. There is concerns with potential impacts on wetlands, water quality, and on rare, threatened and endangered species. These are critical issues that deserve specific attention in the EIS. Comments also indicate that mitigation will be required for wetland loss and implementation of stringent sediment control measure is necessary to help minimize impacts from highway construction. If these issues are anticipated, then every effort must be made to address them early on.

Box 25201 Raleigh, North Carolina 27611 Dear Mr. Vick: UNITED STATES DEPARTMENT OF COMMERCE National Oceanic and Atmospheric Administration NATIONAL MARINE FISHERIES SERVICE Southeast Regional Office 9721 Executive Center Drive N. St. Petersburg, Florida 33702 February 20, 1997 C? Ff8 a o ,o z - 97 The National Marine Fisheries Service (NMFS) has reviewed the Federal Supplemental Draft Environmental Impact Statement (SDEIS) for the Wilmington Bypass, 1-40 to US 421, New Hanover County, North Carolina, Federal-Aid Project No. STPNHF-17(1), State Project No. 8.U250901, TIP No R-2633C. The proposed project is to provide a northern bypass of the City of Wilmington. G=eral C,Qnu1L is - The SDEIS is confusing regarding the impacts of the two alternatives on riverine wetlands adjacent to the Northeast Cape Fear River. It is difficult to determine the differences in the impacts of the two proposed alternatives. The SDEIS should be revised to clarify the impacts of each alternative on riverine wetlands. We are also concerned that the costs of bridging wetlands versus mitigating for wetland losses associated with filled causeways is inadequately addressed. The Southern Alternative would cost an additional $25 million dollars to bridge all wetlands. However, the additional costs for mitigating dir 'toss cf 25 acres of high quality wetlands, if a bridge is not constructed, is not addressed. These additional mitigation costs should be considered if costs are to be used as basis to justify one alternative versus another. The SDEIS identifies 12 additional highway projects involving wetland losses in the vicinity of this project. Given this large number of projects in the Cape Fear and Northeast Cape Fear Rivers area, we believe that a comprehensive assessment of cumulative wetland losses should be a part of the National Environmental Policy Act documents for all projects in this area. I I S.pvcific Comments 2.0 ALTERNATIVE 2.3 TRAFFIC OPERATIONS AND COST ESTIMATES 2.3.3. Cost Estimates Page -34, par?ph2. This Paragraph and Table 2.8 on page 2-35 address the costs associated with the project. It is inappropriate to discuss project costs or develop a table depicting costs that excludes the costs of bridging wetlands and mitigating wetland losses. Pursuant to the 1990 Memorandum of Agreement between the Department of the Army and the Environmental Protection Agency regarding mitigation and the Clean Water Act, wetland avoidance, minimization, and mitigation are a part of the permit process. Therefore, the costs of these activities should be included as a basis for comparing alternatives. The SDEIS should be revised to more clearly identify all costs associated with each alternative. 3.0 AFFECTED ENVIRONMENT 3.3 EXISTING NATURAL ENVIRONMENT 3.3.1 Biotic Communities Table 3.13 INVENTORY OF EXISTING BIOTIC COMMUNITIES Page 352. We recommend that this table be revised to more clearly demonstrate that the total wetland losses include 25 acres of fill in riverine wetlands adjacent to the Northeast Cape Fear River. 4.0 ENVIRONMENTAL CONSEQUENCE 4.2 IMPACTS TO THE PHYSICAL ENVIRONMENT 4.2.1 Hydrology and Drainage 4.2.1.1 River and Stream Crossings page- 4-24- p.aragraph-4. This section states that a bridge length of 730 feet (Table 4.4) would maintain existing drainage patterns. However, it does not address changes in drainage patterns in the adjacent riverine wetlands that would result from the extensive wetland fill approaches required if a 730-foot-long bridge is used. 4.3.3 Aquatic and Fisheries Resources Page-f2,-paragraph-1. The assessment of impacts in this section does not consider the impact of lost wetland functions and values on fishery resources. The SDEIS should be revised to address the impacts of loss of water quality maintenance and habitat functions resulting from the wetland losses. A discussion of the restoration of these functions through a compensatory mitigation plan should also be included in the document. 4.3.4 Protected Species 4.3.4.4 Fish Page-4--6i-paragraph-5. This section addresses impacts on the endangered shortnos the roles of various agencies in addressing these impacts. However, it does not identify e sturgeon and as the lead federal agency responsible for this species. The NMFS's responsibilities for the reviewing NMFS permit applications pursuant to the Clean Water Act also should be listed. 4.4 CONSTRUCTION IMPACTS 4.4.4 Biotic Communities Page- ipb-5• This section inadequately addresses the impacts of the wide range of brid e construction alternatives that could be used. For example, construction techniques may ran the placement of tem o g p mry fill roads in wetlands to dredging canals for barge access.

The National Marine Fisheries Service (NINES) has reviewed the Federal Draft Environmental Impact Statement (DEIS) for Wilmington Bypass, I-40 to US 421, New Hanover County, Federal-Aid Project No. STP-17(1), State Project No. 8.U250901, TIP No. R-2633C. The proposed project is to provide a northern bypass of the City of Wilmington between 1-40 and US 421. The following comments are provided for your consideration. The preferred (southern) alternative is a part of the Greater Wilmington Urban Area Transportation Plan (GWUATP). This plan ultimately involves multiple projects potentially impacting hundreds of acres of wetlands. The NMFS is concerned that the DFIS does not address the cumulative impact of the GWUATP on fishery resources and it is recommended that the DEIS be revised to provide this information. Under the preferred alternative, 7,500 linear feet of filled causeway would be constructed in wetlands. The cost of bridging these wetlands is discussed, but the cost of mitigating for lost wetlands is not. This information is needed to balance the true cost of bridge versus causeway construction. Lastly, the DEIS is inadequate regarding the consideration of mitigation options. Specifically, the purchase and preservation of wetlands is thc only mitigation measure considered. The DEIS should be eM=ded to describe a broader range of potential mitigation options such as wetland restoration and enhancement. nted on Recycled Paper 4 w-0, V-121) 2.0 ALTERNATIVES 2.2 ALTERNATIVES REVIEWED FOR EIWIRONME NTAL CONSEQUENCES 2.2.2 Construction Alternatives EQUENC]ES 2.2.2.1 History of Feasible Alternatives Development page 2-14, paragraph 5 - This section concludes that environmental conditions west of the terminus of the proposed project would not preclude future extension of the bypass.

We have reviewed the information provided with your letter and offer the following comments. • The preliminary alternative corridors depicted in your letter would cross the Cape Fear and Northeast Cape Fear River. These rivers and their tributaries and adjacent wetlands provide habitat for a variety of anadromous and estuarine dependent fishery resources. Alternative highway and bridge alignments under study, cross wetlands and water that support both commercially and recreationally important fisheries. Therefore, we recommend that the EIS include the following: 1. The EIS should address bridge and highway alignment alternatives that will avoid and minimize wetland losses. 2. The EIS should describe the location, species, and acreage of wetlands potentially impacted by the highway alignment alternatives considered. 3. The EIS should provide a description of the aquatic organisms found in the project area and an assessment of the impacts of the project's alternatives on these resources. 4. The EIS should describe construction alternatives that wito minimize wetland avoid loss of these important resources. 5. The alternative analysis in the EIS should demonstrate that the recommended alternative also represents the least environmentally damaging alternative. s 6. Bridge construction often requires access roads and/or excavation of channels access. The EIS should address the impact temporary filling for for barge-construction on wetlands and fishery 3 ' -2- resources of any construction related temporary wetland losses or fishery habitat alternations. 7. If, after avoidance and minimization of wetland involvement, the selected alternative requires unavoidable wetland losses, the EIS should provide a mitigation plan to compensate for wetlands lost. Unless compensation for wetland losses is incorporated as a part of the project, we will likely recommend against the issuance of a Corps of Engineers' Section 10/404 permit for the project. 8. The Cape Fear River supports a population of the endangered shortnose sturgeon (Acipenser brevirostrum) for which we are responsible. Accordingly, you should contact Dr. Terry Henwood of our endangered species staff at Protected Species Management Branch, National Marine Fisheries Service, Southeast Regional Office, 9450 Koger Boulevard, St. Petersburg, Florida 33702, telephone number 813/893-3503. The North Carolina Division of Marine Fisheries is an excellent and reliable source of data concerning specific fishery resources in the project area. A representative of our Beaufort field office is available to discuss National Marine Fisheries Service concerns at any time during this process. Sinc ly our , An eas Mager, .

Box 1890 Wilmington, North Carolina 28402-1890 Attention: Scott McLendon, Regulatory Branch Dear Colonel Youngbluth. This is the report of the U.S. Fish and Wildlife Service (Se.rvice) on Public Notice (PN) ID #199403552, dated February 27, 1997. The North Carolina Department of Transportationto (NCDOT) has applied for a,Department of the Army (DOA) permit fill jurisdictional wetlands in conjunction with the construction of a portion of the Wilmington Bypass, New Hanover County, North Carolina (TIP No. R-2633C). The PN states that two alternatives are under consideration and that wetland losses are estimated to range from 130 acres (Southern Alternative) to 116 acres (Central Alternative). The PN requests comments on these alternatives. This report is submitted in accordance with the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d), and Section 7 of the Endangered Species Act (ESA) of 1973, as amended (16 U.S.C. 1531-1543). It is to be used in your determination of compliance with the Environmental Protection Agency's 404(b) (1) Guidelines (40 CFR 230) and in your public interest review (33 CFR 320.4) as they relate to protection of fish and wildlife resources. According to information provided in the PN, to construct a four-lane, divided freeway on new location. Both build alternatives would interchanges at US 421, US 117/NC133, and I- alternatives would require a new bridge•.over Fear River. the NCDOT proposes about 7.8 miles of provide 40. Both build the Northeast Cape The wetlands in the project area represent very valuable fish and wildlife habitat. The proposed project would produce permanent losses of tidal freshwater marsh, tidal cypress-gum swamp, pocosin wetlands, freshwater bottomland hardwood forest, and wet pine flatwoods. The Service strongly recommends that the District Engineer ensure that this project does not result in any loss of the many functions and values provided by the wetlands in the project area, especially the riverine areas adjacent to the Northeast Cape Fear River. We are concerned that the alternative as currently designed have not incorporated all practical measures to avoid and minimize wetland impacts. Unavoidable losses should be mitigated to ensure that there is no net loss of the functions and values provided by these wetlands. The PN states that the NCDOT is investigating mitigation opportunities in the project area. However, a mitigation proposal is not ready,at this time. The Service has stated in previous comments on NCDOT projects that compensatory mitigation should be developed early in the planning process. The complete absence of a compensatory mitigation plan precludes any realistic assessment of the long-term impacts or the project on fish and wildlife resources. The Service provided _vour o_-'ice with the comments of the Department of interior, dated February 24, 1997, on potential project impacts on federally protected species based on information contained i^ the Supplemental Environmental T Statement released in December 1996. The Service requested that additional justification was required to support a determination that the project was not likely to adversely affect the rough- leaved loosestrife (L_vsimachia asperulaefolia) and Coole.y's meadowrue (Thalictrum cooleyi). Therefore, the requirements of Section 7 of the ESA have not been fulfilled at this time. In summary, the Service believes that the proposed activities I will have a significant ant irreversible adverse impact on fish and wildlife resources. We feel that the NCDOT has inadequately ' addressed avoidance and minimization measures recommended by the Service in previous comments on NCDOT projects. In the absence of a revised alternative which would truly avoid and minimize wetland impacts, the Service would recommend denial of a permit for this project. The above findings and recommendations constitute the report of the Service. In accordance with the ' procedural requirements of the 1992 4041'(q)', Memorandum of I Agreement, Part IV.3(a), we are advising you that the proposed work may result in substantial and unacceptable impacts, to acuatic resources of national importance. The Service appreciates the opportunity to comment on this public notice. Please advise us of any action taken by the Wilmington District, Corps of Engineers on this permit application.

Russell Federal Building 75 spring street, S.W. Atlanta, Georgia 30903 Q C + February 24, 1997 Nicholas L. Graf, P. E. Federal Highway Administration 310 New Bern Avenue, Suite 410 Raleigh, NC 27601 Dear Mr. Graf: Ffe rt AL? The Department of the Interior has reviewed the Supplemental Draft Environmental Impact Statement (DEIS) for the Wilmington Bypass, I- 40 to US-421 in New Hanover County, NC, as requested. The Fish and Wildlife Service (FWS) comments in this letter are provided in accordance with the Fish and Wildlife Coordination Act, as amended, (16 USC 661-667d) and Sec. 7 of the Endangered Species Act of 1973, as amended, .(16 USC 1531-1543). The Department's comments on the DEIS for this project dated April 21, 1995, expressed concern that the overall Wilmington Bypass had been divided into three segments. While each segment would have a certain independent utility, the construction of a single segment would dictate, to some degree, 'the alignment of other segments. The construction of a single segment could serve as a justification for the construction of other segments. While the FWS concurred with an interagency agreement to resolve the segmentation issue by the concurrent release of separate National Environmental Policy Act (NEPA) documents for the central and western sections of the bypass, we believe that the three sections of the bypass are interdependent and that a review of the overall bypass project would have been facilitated by the preparation of a single NEPA document. The wetlands in the project area represent very valuable fish and wildlife habitat. The proposed project would produce permanent losses of tidal freshwater marsh, tidal cypress gum swamp, pocosin wetlands, freshwater bottom land hardwood forest, and wet pine flatwoods. We believe that every effort should be made to avoid and minimize the permanent loss of these wetland areas, including the bridging of all riparian wetlands. If unavoidable losses occur, there should be sufficient compensation to ensure that there is no net loss of the functions and values provided by these wetlands. u Analysis of Alternatives The SDEIS states (p. 2-15) that the western terminus of the project would be I-40. There would be an interchange at the junction with I-40. The document notes (p. 2-15) that the project termini "at I- 40 and US 421 are logical endpoints." However, a statement which appears to occur only in the summary section (p. S-2) states that a "5,800-foot extension east of I-40 is necessary to completely develop the interchange movements.." Exhibit 8 of the Natural Systems Technical Memorandum (NSTM), dated October 1996, shows the eastern end of this extension in a wetland area. We question the need for any interchange development to extend 1.1 mile from I-40 and whether the eastern end of this extension represents a true "logical terminus" for transportation purposes between US 421 and I-40. The issue of termini for this project" concerns us because there will be a desire to link adjacent sections of the project to these points. Any work east of I-40 would restrict the alignment of the segment which will be built from US 17 to I-40 (TIP No. R-2405). Our comment on the 1995 DEIS noted that the upgrading of Sidbury Road was an alternative to the new location corridors proposed by the NCDOT. ' We recommend that the Final Environmental Impact Statement (FEIS) fully explain the need for this 1.1-mile extension and support the eastern end of the' extension as a logical terminus for this project. We also recommend that the FEIS specifically address the utility of the 1.1 mile extension in the event that 8- 2405 is not build or is designed to meet I-40 either north or south of the interchange proposed for this project. In reference to the other parts of the Wilmington Bypass, the SDEIS notes (p. 2-15) that the two alternatives for this project would "not restrict consideration of other alternatives." We disagree with this statement. Any significant extension of the present project on new location to the east of I-40 would seem to severely restrict the range of alternatives which would be feasible for R- 2405, and would enhance the selection of a new location corridor for the eastern portion of the overall Wilmington Bypass. Figure 2.3 indicates that the eastern terminus of R-2633C will join R-2405 and the western terminus of R-2633C will join R-2633A/B. The overall goal of the project is to construct a single route to join US 17 northeast and southwest of Wilmington. We believe that current plans to connect these three segments will result in the central segment, the subject of this SDEIS, controlling, to some extent, the corridors of the eastern and western parts. The SDEIS presents two alternatives, the southern and center alternatives. Section 2 presents a detailed analysis of the selection and justification of these alternatives. The document 2 does not give a preference between the alternatives. In the narrow context of the single project considered in this SDEIS, the FWS attended interagency meetings which worked to develop alternatives for the central part of the overall bypass. We believe that the analysis which led to the corridors between US 421 and I-40 is adequate. The FWS would like to provide comments on the final design features and eventual alignment on the highway within the corridor selected. We strongly recommend that the final design include features to ensure that the project does not disrupt hydrological flow within the project area. Furthermore, we recommend that the final design includes measures to allow the passage of amphibians, reptiles, and small mammals. Wetland Losses and Mitigation Section 3 presents a comprehensive discussion of the social and natural environmental features of the project area. Table 3-13 (pp. 3-51/52) presents an outline of the biotic communities which would be impacted by the project. The total wetland impacts, based on a 300-foot right-of-way,-would be 133 and 118 acres for the southern and center alternative, respectively. The FWS is especially concerned that both alternatives would pass through the proposed 2,800-acre conservation area along the Northeast Cape Fear River. As noted in the SDEIS (p. 3-63), this area consists of wetlands, bluffs, and buffer strips on both sides of the river. Under the 404(b)(1) guidelines of the Environmental Protection Agency, we understand that the NCDOT should first endeavor to avoid, then minimize, and finally compensate for wetland losses of the project. The SDEIS discusses (p. 4-61) "potential measures to reduce impacts to wetlands." However, the document does not state which, if any, measures will actually be used for the project. While noting that bridging of the wetland along the Northeast Cape Fear River would reduce wetland impacts, the NCDOT has apparently only given "consideration" to this design feature. We recommend that all feasible design features and construction techniques be employed to minimize the permanent loss of wetlands. These measures would include, at a minimum, steeper side slopes for fill, the elimination of lateral drainage ditches, reduced median widths through wetlands, and the bridging of riparian wetlands along the Northeast Cape Fear River. Despite all efforts for avoidance and minimization, this project is likely to result in some permanent wetland losses. However, the SDEIS does not present a fully developed plan for compensatory I mitigation. The document indicates (p. 4-61) that a potential mitigation site would be areas within a 2,800-acre tract along the Northeast Cape Fear River which has been proposed as a conservation area by the Wilmington District of the U. S. Army Corps of Engineer. The FWS recognizes the high value of this area, but we 3 are concerned that compensation within this area may involve the purchase of relatively undisturbed wetlands which could, in time, be purchased by the Corps. The preservation of this area has been designated as a separate fish and wildlife enhancement feature of the Corps' dredging projects associated with the Wilmington ship channel, and the Corps' proposal calls for the area to be used for conservation purposes. Therefore, the FWS is concerned that the use of parts of this tract by the NCDOT as compensation could lead to a situation where two agencies were seeking to use the same land in conjunction with two different projects. Furthermore, compensatory mitigation within this area may rely exclusively on wetlands. The the preservation ave reservati nos about relatively lcompensat compensatory FWS would on plan which relied entirely on preservation. We strongly encourage locating disturbed and/degraded wetlands along the lower Northeast Cape Fear River which could be restored and/or enhanced. While preservation of existing wetlands can be an important part of a comprehensive plan which is centered on restoration and/or enhancement, the use,.of wetland preservation to areas a ne? loss compensate for the permanent loss of wetlands results of the functions and values provided by project will result in a net loss of wetland functions and values, this loss should be documented in the FEIS. Federally-listed Species Section 4.3.4 of the SDEIS (pp. 4-62/65) discusses project impacts 3-56) that on federally-protected species. The document notes (p• habitat for two federally-endangered plants is available in the project area. These are the rough-leaved loosestrife (1ysimacThe asperulaefolia) and Cooley's meadowrue (Thalictrum cooleyi). SDEIS states that "previous field surveys" indicate that these species do not occur within the alternative corridors and concludes that the project is not likely to adversely affect these species. The protected species section of the October 1996 NSTM contain similar language. Page 17 of the NSTM provides only a cursory description of field survey methodologies and provides no specific information on surveys for protected species. The FWS believes that a more detailed justification for project impacts to these two listed species should be provided. The SDEIS concludes (p. 4-64) that the project is not *likely to adversely affect the West Indian manatee (Trichechus manatus), a federally-endangered aquatic mammal. This conclusion is based, in part, on the opinion that the project area is in the "extreme northern range" of the species. Data have been published ust souwhich document manatees at the port facility in Wilmington, j of the project area, and in the Northeast Cape F area River in Plater county, several miles upriver from the project the FWS regards the instance is cited in the NSTM.

The FWS further -ecommenda that the comprehensive mitigation plan be included in the FEIS. V The proposed project would cross the area which has been designated as environmental enhancement lands by the COE as part of the Wilmington Harbor. Northeast Cape Fear River water resources development project. The FWS believes that impacts to this area should be minimized to the maximum extent possible and recommends a series of methods to reduce these impacts. The DEIS presents.an adequate discussion of potential impacts to federally-listed species. The FWS is pleased that field searches were made for the red-cockaded woodpecker (Picoldds borealis). Based on information in the DSIS, the FWS concurs that the project is not likely to affect federally-listed endangered or threatened species. The FWS, however, believes that it would be prudent for the NCDOT to consider the 14 candidate species for Federal listing in project planning, and we strongly encourage NCDOT to address this issue in the FEIS. The FWS concerns related to wetland losses and secondary and cumulative impacts of this project are -substantial. Depending on the proposal included in the FEIS, the FWS may recommend referring this project to the Council on Environmental Quality under Section 1504 of the Council's Regulations for Implementing the Procedural Provisions of the National Environmental Policy Act. We do, however, wish to coordinate fully at the earliest possible time and avoid any delays in addressing transportation needs for this area, and preclude the necessity for referral. Coordination can be initiated by contacting the Field Supervisor, Division of Ecological Services, U.S. Fish and Wildlife Service, D.O. Box 33726, Raleigh, North Carolina 27636-3726, telephone (919) 056-4520. The National Park Service (NPS) indicates that the DSIS provides an excellent evaluation of the impact of alternatives on historic and archeological sites. The NPS indicates that neither the Southern Preferred Alternative or the Northern Alternative will impact the Thornbury and Nesses Creek Plantation Archeological Districts. The NPS also notes that there are no prehistoric sites identified which would be affected by the Southern Alternative and that four sites may be eligible for the National Register of Historic Places. In correspondence included in the D$IS, the North Carolina State Historic Preservation officer I (SHPO) indicates that these sites may be salvaged and are not site-significant. The NPS notes that the crossing or the Northeast Cape Year River has potential with either construction alternative to impact underwater archeological sites. However, the NCDOT agrees to an underwater archeological survey on the selected alternative. Therefore, based on the information presented in the DEIS including correspondence from the SHPO, the MPS agrees with the determination in the DSIS that there are no Section 4(f) involvements with historic and archeological sites. The DEIS does not identify that any recreational sites will be impacted for Section 4(f) or section 6(f) involvements, SPECIFIC COMMStas Aaalysis of the A_lteeygtivge and the Selection of Preferred Alternative, paces 2-2 to 2-22 The DEIS presents an extensive discussion of the development of alternative routes. The DEIS describes the process by which the 36 preliminary alternatives were reduced to two final alternatives, a Northern and Southern Alternative. The NCDOT has selected the Southern Alternative as the preferred route. The FWS is very concerned about the selection of the Southern Alternative for this section of Wilmington Bypass an it relates to the alignment of the other segments. The Wilmington Bypass, as currently conceived, would have three ' sections which are from northeast to southwest: (1) the link from U9 17 to I-40 (TIP No. R-2405) ; (2) the segment under current review from I-40 to US 412 (TIP i Bishop.

It is indicated in Table 3.13 that based on the 300-foot right-of-way, the Preferred Southern Alternative would impact 178 acres of wetlands, a total of 62 percent of the area impacted. The highest wetlands impact would occur in pond pine forests (101 acres), bottomland hardwoods (31 acres), and mixed hardwoods (18 acres), the FWS recognizes that these losses are less than those associated with the Northern Alternative, which would impact 199 wetland acres. Based on a consideration of only the final two build alternatives, the Preferred Southern Route apparently would result in less wetlands impact. Wetlands, losses could be further reduced by using the above-described design and construction techniques and by employing mitigation in the context of the Council on Environmental Quality's National Environmental Policy Act regulations. . Despite design and construction features to avoid and minimize wetland losses, it is indicated that some unavoidable wetland losses will occur and compensatory mitigation will be required. The FWS recommends that the lead agency include a wetland mitigation plan for unavoidable wetlands losses, including direct, indirect, and cumulative losses, associated with the project in the PEIS.. The PWS will evaluate this plan in accordance with our Mitigation Policy which considers the Resource Categories of wetlands impacted. This plan, at a minimum, must include the following parts: A. the amount (in acres) and a measure of the habitat value for each type of wetlands lost based on the National Wetlands Inventory/Cowardin classification system; b. the proposed mitigation for each wetland type: either in-kind or out-or- kind; C. the amount (in acres) of each community type to be used for compeneatory wetlands; d. the location of areas to ba used for compensation wetlands; e. the present use, condition, and wetland jurisdictional statue of areas to be used for compensation wetlands; f. the disposition of compensation wetlands (i.e., who will own, manage, and protect the compensation wetlands in perpetuity) ; g, a work plan which details the initial procedures which will be used to change the present condition of each type of compensation area into a given wetland type lost during construction (i.e., land clearing piano, site preparation, species to be planted, etc.); h. a mitigation schedule which gives a timeframe for several intermediate goals and a final goal for the conversion of each area used for compensation to the desired functional wetland; and, a contingency plan which will state the actions to be taken if the goals of the mitigation schedule are not achieved. Regarding the location of compensatory wetlands, the PWS considers areas in the immediate vicinity of the wetlands lost to be preferable to off-site compensation. The issue of replacing habitat value rather than simply replacing lost acreage should be addressed in the mitigation plan.

These comments are provided in accordance with provisions of the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e) and Section 7 of Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543). The U.S. Fish and Wildlife Service (Service) is particularly concerned about potential impacts of the proposed project upon stream ecosystems and associated wetlands within the study corridor. At least eight stream and wetland crossings are present in the study corridor. Special care should be exercised in the design and implementation of all stream crossing structures. The attached pages identify the Federally-listed endangered (E) and threatened (T) species which may occur in the proposed project corridor. If the proposed project will be removing pines greater than or equal to 30 years of age in pine or pine/hardwood habitat, surveys should be conducted for active red-cockaded woodpecker cavity trees in appropriate habitat within a 1/2 mile radius of project boundaries. If red-cockaded woodpeckers are observed within the project area or active cavity trees found, the project has the potential to adversely affect the red-cockaded woodpecker and you should contact this office for further information. The Service's review of any environmental document would be greatly facilitated if it contained the following information: 1) A description of the fishery and wildlife resources within existing and required additional right-of-way and any areas, such as borrow areas, which may be affected directly or indirectly by the proposed improvements. 2) Acreage of branches, creeks, streams, rivers or wetlands to be filled. Wetlands affected by the proposed project should be mapped in accordance with the Federal Manual for Identifvina and Delineatina Jurisdictional Wetlands. 3) Linear feet of any water courses relocated. 4) Acreage of upland habitats, by cover type, which would be eliminated. 5) Techniques which will be employed for designing and constructing any relocated stream channels or for creating replacement wetlands. 6) Mitigation measures which will be employed to avoid, eliminate, reduce or compensate for habitat value losses associated with any of the proposed improvements. 7) Assessments of the expected secondary and cumulative impacts of the proposed project on fish and wildlife resources. • Sincerely yours, L.K.

Youngbluth District Engineer, Wilmington District Department of the Army, Corps of Engineers P. O. Box 1390 Wilmington, North Carolina 23402-1890 Attention Scott McLendon Dear Colonel Youngbluth: In accordance with Part IV, Section 3(a) of the current Memorandum of Agreement (MOA) between the Departments of Commerce and the Army, I am notifying you of the National Marine Fisheries Service's (NMFS) intent to consider referral of Department of the Army (DOA) permit application 199403552 dated February 27, 1997. At issue is the request by the North Carolina Department of Transportation (NCDOT) to place fill material in waters and wetlands adjacent to the Northeast Cape Fear River, Ness Creels, and other unnamed tributaries of the Northeast Cape Fear River to construct the Wilmington Bypass north of Wilmington, New Hanover County, North Carolina. This letter details reasons: (1) why there may be substantial and unacceptable adverse impacts to aquatic resources of national importance; and (2) why issuance of the specified permit must be conditioned or denied to protect these resources. The proposed project consists of the construction of 7.3 miles of 4-lane median divided freeway from east of I-40 to US 421 west of the Northeast Cape Fear River. The typical cross section includes a 46-foot-wide grassed median. A high rise bridge with a 65 foot vertical clearance will be constructed over the Northeast Cape Fear River. The Draft Environmental Impact Statement (DEIS) which was circulated in January 1995 described two alternative alignments for the highway, a Southern Alternative and a NorthernAlternative. A Supplemental Draft Environmental Impact Statement (SDEIS), which addressed a new Central Alternative, was circulated for review in December 1996. Based on substantial adverse impacts to natural and cultural resources, the Northern Alternative was eliminated from further consideration in April 1996. I f Wetlands impacted by the project include a mixture of bottomland hardwoods, tidal, fresh, and saltwater marsh, tidal cypress and gum swamp, pocosin, and wet pine flats. Total wetland impacts would be 130 acres and 116 acres of wetlands for the Southern and Central Alternatives, respectively. 0 Ponied.ni Recycled Palkr Weiland species commonly found in the project area include bald cypress (Taxodium distichum), tupelo gum (Nvssa aquatica), black gum (Nyssa sylvatica), green ash (Fraxinus pennsvlvanica), swamp black gum yssa svivatica), sweet gum (L.iguidambar stvraciflua), loblolly pine (Pinus taeda), wax myrtle erica cerifera), cattail Jypha sp.), soft rush (Juncus effusus), and saw grass (Cladium iLtmaicense). These wetlands perform a variety of important functions including providing habitat for aquatic species and water quality maintenance functions. Wetlands adjacent to uplands function to slow storm water run-off and trap excessive sediments, nutrients, and pollutants before they can reach surface waters, thereby, aiding in the maintenance of water quality.' By removing excessive sediments, nutrients, and pollutants from adjacent waters during periods of seasonal flooding, seasonally and tidally flooded wooded wetlands and marshes also function to maintain water quality in the Northeast Cape Fear River.' These wetlands are also a source of primary productivity and provide a source of detritus, an important component in the aquatic food chain supporting fishery resources. When flooded these wetlands also provide important nursery area functions for a host of estuarine dependent and anadromous fish and shellfish.' The Northeast Cape Fear River and its tributaries and adjacent wetlands, including portions of the project area, have been designated as primary nursery areas (PNA) by the North Carolina Division of Marine Fisheries. PNAs are defined as those areas in which, for reasons such as food, cover, bottom type, salinity, temperature, and other factors, young finfish and crustaceans spend the major portion of their initial growing season.` This designation reemphasizes the importance of these wetlands-to the continued production of fishery resources. Commercially and recreationally important, fishery resources found in the project area include estuarine dependent species such as spot (Leiostomus xanthurus), flounders (Paralichthvs spp.), Atlantic croaker (Microoogonias undulatus), striped mullet (Mugil cephalus), shrimp enaeus spp.), and blue crab (Callinectes sa idus . These species are identified in Section 906(e)(1) of the Water Resources Development Act of 1986 (PL 99-602) as species of "national economic importance". A fishery management plan (FMP) for shrimp has been developed by the South Atlantic Fishery Management Council (SAFMC) because shrimp stocks are reduced. Additionally, the Mid-Atlantic Fishery Management Council, in cooperation with the SAFMC, has developed FMPs for summer flounder. The FMP for shrimp and flounder specify rigorous management and protection of the managed species and their essential habitat. =NC Coastal Nonpoint Pollution Control Program. 1995.

Anadromous fishery resources are dependent on hardwood swamps for annual pulses of detritus which form the basis of complex food webs that support fish productivity in the ecological system.' In recent years, landings of these important species have declined which has been attributed to declines in water quality and losses of habitat.' Under the Atlantic Coastal Fisheries Cooperative Management Act of 1993, the Atlantic States Marine Fisheries Commission is developing management plans for these species which include protection of managed species and their essential habitats. Accordingly, we regard these fishery resources and their associated habitat as aquatic resources of "national economic importance". The NMFS has been involved with this project since its onset in 1989, including on-site inspections, interagency meetings, and the review of the DEIS and SDEIS. Based on this involvement, we believe that the wetland losses associated with either alternative will be detrimental to NMFS trust resources. However, we believe that the Center Alternative is environmentally preferable to the Southern Alternative since the overall wetland losses are less with the Center Alternative and it includes bridging of all wetlands located adjacent to the Northeast Cape Fear River. The Southern Alternative is totally unacceptable since it does not bridge riverine wetlands and involves the loss of more wetland acreage. EverLthougb this project has been in the planning stage for a considerable time, there remains many issues that must be resolved before the NMFS can recommend authorization for this work. The goals of wetland avoidance and impact minimization, as well as provisions for adequate mitigation for unavoidable wetland losses, must be achieved prior to federal authorization for this work. To accomplish these goals the following criteria or standards must be met: 1. All riverine wetlands must be bridged with bridge design and construction techniques being selected to minimize impacts to wetlands and fishery resources. Impacts associated with construction techniques are of great concern to the NMFS in areas which support an annual anadromous fish migration. The use of construction techniques which minimize impacts to fisheries is essential for agreement on federal authorization by the NMFS. 2 Primary nursery areas must be protected from discharges of storm water run-ofi both temporary and permanent, as well as, other pollutants associated with highway and bridge construction. 3.

Post Office Box 1890 Wilmington, NC 28402-1890 Dear Mr. McLendon: SECRETARY SUBJECT: New Hanover County, Bridge on US 17 Wilmington Bypass over the COQ. Northeast Cape Fear River, TIP No. R-2633CA, State Project 8.U250901 G7 The N.C. Department of Transportation (NCDOT) proposed in its January 7, 1998 application to construct the Wilmington Bypass from US Route 421 (US 421) to approximately 5,800 feet east of Interstate 40 (I-40). The NCDOT's Soils and Foundation Design Section proposes to conduct a foundation loadtest on R-2633CA. The foundation loadtest will occur on Rat Island and in the east channel of the Northeast Cape Fear River. The loadtest will provide information on the existing subsurface conditions at the site in order to design the most economical bridge and uncover any potential construction problems associated with the site and its geology. The foundation loadtest plan consists of three elements: geotechnical tests and tests performed at Test Areas 1 and 2. Geotechnical tests involve SPT borings and CPT, dilatometer, and vane shear tests. Test Areas 1 and 2 include lateral statnamic, Osterberg Cell, and lateral static tests. Specific activities conducted during the proposed work include drilling drilled piers with bentonite slurry; constructing a reinforced concrete cap; driving, extracting, and re-driving steel piles; and advancing and extracting pre-stressed concrete (PSC) piles. Please see the enclosed foundation loadtest plan for more details on the type of work proposed. The foundation loadtest impacts 0.002 acres of waters of the United States. Measures taken to minimize the impacts include performing construction from barges and temporary platforms, accessing the site via water, demolishing all aboveground structures, and the absence of dredging activities. The NCDOT hereby applies for a Nationwide 6 permit for the proposed foundation loadtest. If you have any questions, please feel free to contact Gordon Cashin at 919- 733-7844 extension 278.

Bowers, P.E., Division 3 Engineer Ms. Leigh Lane, Project Planning Engineer FOUNDATION LOADTEST PLAN R-2633CA BRIDGE OVER NE CAPE FEAR RIVER US 17 WILMINGTON BYPASS NEW HANOVER COUNTY Primary Goals 1. To develop unit tip bearing and skin friction values for use in design of the drilled shafts for axial capacity. 2. To develop lateral capacities for use in the design of the drilled shafts for ship impact in the East Channel. 3. To develop lateral capacities for the alluvial soils and muck for the design of the approach span structures. 4. Learn about potential construction problems associated with this specific site and geology. Significant Cost Saving Areas: 1. Primarily, expect a reduction in drilled shaft lengths due to increased axial capacities and a reduced factor of safety (increased level of confidence). A reduction in shaft diameters may also be possible depending on drilled shaft lateral capacities. 2. Possibly, expect to utilize pre-stressed concrete (PSC) piles for the approach span structures as opposed to drilled shafts. This will not only depend upon the loadtest results but also upon scour elevations. 3. Also, expect to reduce potential for claims and costs associated with construction of the foundations. Geotechnical Testing Sequence and Description of Tests- 1. SPT borings at each NCHRP Group location, drilled shafts location, PSC piles location. 2. CPT testing with pressuremeter at each NCHRP Group location and the PSC piles location. 3. Dilatometer testing at each NCHRP Group location and the PSC piles location. 4. Vane shear testing on Rat Island. Test Area 1 Sequence and Description of Tests- 1. Lateral statnamic test on NCHRP Group (approximately 80,000 lb. test) on Rat Island to test muck. 2. Series of Osterberg Cell tests on the two 84" drilled shafts without the cap to test axial capacities. One shaft would tip in hard clay and would contain two 3000 ton cells (one at the bottom and one in the dense sand). The other shaft would tip in dense sand and contain one 3000 ton cell at the bottom. 3. Lateral static test on NCHRP Group on Rat Island by pulling drilled shafts and group together to test muck. 4. Lateral static test on NCHRP single piles by pushing apart for comparison to the group. 5. Lateral statnamic test on the two 84" drilled shafts with the cap (approximately 120,000 lb. test) to test lateral capacities of the dense sand (Pedee Formation). Test Area 2 Sequence and Description of Tests- 1. Driving, restriking and PDA measurements on both the 30" PSC square pile with a steel H-pile stinger and a 36" PSC cylinder pile. Pile lengths would range from 70 to 110 feet. Hammer energies required are expected to range from 120 to 160 ft-kips. Jetting and drilling during driving would be expected in order to advance the cylinder pile as far as possible into the Pedee formation. The 30" PSC pile would be pulled after driving to observe the condition of the pile. 2. Lateral static test on the PSC piles by pushing them apart and using NCDOT frame to test loose alluvial soils. 3. Lateral statnamic test on NCHRP Group (approximately 80.000 lb. test) to test loose alluvial soils. 4. Lateral static test on NCHRP single piles by pushing apart for comparison to the group. Additional Comments and Details 1. Test Area 2 may be moved to deeper water if during geotechnical testing phase it is found that the proposed location has shallower than expected water. 2. We expect to have 5 barges and 2 cranes to perform this construction. 3. The drilled shafts and the concrete piles (if they can not be removed) will be left in place for demolition during the actual bridge construction. 4. Bentonite slurry will be used during the construction of the drilled shafts. All applicable permits will be obtained by the contractor for the slurry use prior to beginning construction. 5. A temporary work platform will be constructed on the banks of Rat Island in order to perform the lateral statnamic on the NCHRP Group in Test Area 1. All other work will be performed from barges. Site access will be by water frgm either down or up river. Item 12 - Description of proposed work. Foundation Loadtest Plan will include the following- 1. Drilling 2 2.13 m diameter drilled piers. The drilled piers will be drilled with bentonite slurry and all cuttings, as well as the slurry, will be disposed of off site. Fresh water for the bentonite slurry will be drawn from either a well onsite or piped in from off site. 2.13 m diameter steel casing will be used during drilling and remain in place during testing. The steel casing will extend from the top of the each pier to elevation -11 m. 2. Constructing a reinforced concrete cap. The bottom of the cap will be at approximately elevation 0 m and the top of the cap will be at approximately elevation 5 m. According to the US Army Corps of Engineers' control tide station located in Wilmington, NC, the mean high water elevation for the NE Cape Fear River is.85 m. The cap and the drilled piers will be demolished and removed down to the mudline by blasting after completion of testing. 3. 8 .27 m diameter steel piles will be driven, extracted and driven again in two different locations. 4 other .27 m diameter steel piles will be driven. extracted and redriven in three different locations. In some cases, the steel piles may be vibrated in. All the steel piles will be extracted and removed from the site after completion of testing. 4. One .76 m square pre-stressed concrete pile and one .91 m pre-stressed concrete cylinder pile will be driven. Methods to advance the piles to the required depth may include jetting while driving, pre-jetting and augering while driving. The square pile will have a steel pile stinger on the end approximately 3.5 meters in length. The square pile will be extracted and removed from the site after completion of testing. The cylinder pile will be demolished and removed by blasting or cutting down to the mudline after completion of testing. 1 Hayn A.

Project Review Coordinator RE: 91-0591 - Scoping. Wilmington Bypass Brunswick and New Hanover Counties DATE: March 25, 1991 The Department of Environment, Health, and Natural Resources has reviewed the Department of Transportation's (DOT) scoping notice to construct the Wilmington Bypass in Brunswick and New Hanover Counties. The information that was circulated for review was not sufficient to evaluate potential environmental impacts of this project. However, our review efforts did raise a number of specific issues that will need to be fully addressed in the proposed EIS. In reviewing our comments it is evident that DOT's preliminary selection of bypass corridors will have impacts of the environment. There is concerns with potential impacts on wetlands, water quality, and on rare, threatened and endangered species. These are critical issues that deserve specific attention in the EIS. Comments also indicate that mitigation will be required for wetland loss and implementation of stringent sediment control measure is necessary to help minimize impacts from highway construction. If these issues are anticipated, then every effort must be made to address them early on. Thank you for the opportunity to respond. Our divisions ' welcome the opportunity to work with the Department of Transportation throughout all phases of this project. ?i-?.• . f MM : bb li Attachments riHr or co ? ?? tf J'4"' 01 Mr. H. Franklin Vick, P.E., Manager Planning and Environmental Branch N.C. Division of Highways P.O. Box 25201 Raleigh, North Carolina 27611 Dear Mr. Vick: UNITED STATES DEPARTMENT OF COMMERCE National Oceanic and Atmospheric Administration NATIONAL MARINE FISHERIES SERVICE Southeast Regional Office 9721 Executive Center Drive N. St. Petersburg, Florida 33702 February 20, 1997 b fE??o to z - 97 The National Marine Fisheries Service (NMFS) has reviewed the Federal Supplemental Draft Environmental Impact Statement (SDEIS) for the Wilmington Bypass, 1-40 to US 421, New Hanover County, North Carolina, Federal-Aid Project No. STPNHF-17(1), State Project No. 8.U250901, TIP No R-2633C. The proposed project is to provide a northern bypass of the City of Wilmington. Gmeral 'o?mments The SDEIS is confusing regarding the impacts of the two alternatives on riverine wetlands adjacent to the Northeast Cape Fear River. It is difficult to determine the differences in the impacts of the two proposed alternatives. The SDEIS should be revised to clarify the impacts of each alternative on riverine wetlands. We are also concerned that the costs of bridging wetlands versus mitigating for wetland losses associated with filled causeways is inadequately addressed. The Southern Alternative would cost an additional $25 million dollars to bridge all wetlands. However, the additional costs for miligating dic fuss df 25 acres of high quality wetlands, if a bridge is not constructed, is not addressed. These additional mitigation costs should be considered if costs are to be used as basis to justify one alternative versus another. The SDEIS identifies 12 additional highway projects involving wetland losses in the vicinity of this project. Given this large number of projects in the Cape Fear and Northeast Cape Fear Rivers area, we believe that a comprehensive assessment of cumulative wetland losses should be a part of the National Environmental Policy Act documents for all projects in this area. I Specific Comments 2.0 ALTERNATIVES 2.3 TRAFFIC OPERATIONS AND COST ESTIMATES 2.3.3. Cost Estimates Page -34, paragraph-2. This paragraph and Table 2.8 on page 2-35 address the costs associated with the project. It is inappropriate to discuss project costs or develop a table depicting costs that excludes the costs of bridging wetlands and mitigating wetland losses. Pursuant to the 1990 Memorandum of Agreement between the Department of the Army and the Environmental Protection Agency regarding mitigation and the Clean Water Act, wetland avoidance, minimization, and mitigation are a part of the permit process. Therefore, the costs of these activities should be included as a basis for comparing alternatives. The SDEIS should be revised to more clearly identify all costs associated with each alternative. 3.0 AFFECTED ENVIRONMENT 3.3 EXISTING NATURAL ENVIRONMENT 3.3.1 Biotic Communities Table 3.13 INVENTORY OF EXISTING BIOTIC COMMUNITIES Page 3-5 .

The National Marine Fisheries Service (NMFS) has reviewed the Federal Draft Environmental Impact Statement (DEIS) for Wilmington Bypass, I-40 to US 421, New Hanover County, Federal-Aid Project No. STP-17(1), State Project No. 8.U250901, TfP No. R-2633C. The proposed project is to provide a northern bypass of the City of Wilmington between 1-40 and US 421. The following comments are provided for your consideration. The preferred (southern) alternative is a part of the Greater Wilmington Urban Area Transportation Plan (GWUATP). This plan ultimately involves multiple projects potentially impacting hundreds of acres of wetlands. The NMFS is concerned that the DES does not address the cumulative impact of the GWUATP on fishery resources and it is recommended that the DEIS be revised to provide this information. Under the preferred alternative, 7,500 linear feet of filled causeway would be constructed in wetlands. The cost of bridging these wetlands is discussed, but the cost of mitigating for lost wetlands is not. This information is needed to balance the true cost of bridge versus causeway construction. Lastly, the DEIS is inadequate regarding the consideration of mitigation options. Specificall y, the purchase and preservation of wetlands is the only mitigation measure considered. The DEIS should be expanded to describe a broader range of potential mitigation options such as wetland restoration and enhancement. nted on Reo'cled Paper ( ?o '1, 2.0 ALTERNATIVES 2.2 ALTERNATIVES REVIEWED FOR ENVIRONMENTAL CONSEQUENCES 2.2.2 Construction Alternatives 2.2.2.1 History of Feasible Alternatives Development Page 2-14, paragraph 5 - This section concludes that environmental conditions west of the terminus of the proposed project would not preclude future extension of the bypass.

'Bypass; Brunswick and New Hanover Counties, N.C., State Project No. 6.258001T; TIP No. R-2633. We have reviewed the information provided with your letter and offer the following comments. • The preliminary alternative corridors depicted in your letter would cross the Cape Fear and Northeast Cape Fear River. These rivers and their tributaries and adjacent wetlands provide habitat for a variety of anadromous and estuarine dependent fishery resources. Alternative highway and bridge alignments under study, cross wetlands and water that support both commercially and recreationally important fisheries. Therefore, we recommend that the EIS include the following: 1. The EIS should address bridge and highway alignment alternatives that will avoid and minimize wetland losses. 2. The EIS should describe the location, species, and acreage of wetlands potentially impacted by the highway alignment alternatives considered. ' 3. The EIS should provide a description of the aquatic organisms found in the project area and an assessment of the impacts of the project's alternatives on these resources. The EIS u construction alternatives l m to minimize wetland losses. We recommend bridging all wetlands avoid loss of these important resources. lethat 5. The alternative altanalysis ernati e n also IS reshould presents demonstrate ast the recommended environmentally damaging alternative. 6. Bridge construction often requires temporary filling for access roads and/or excavation of channels for barge... construction access. The EIS should address the impact on wetlands and fishery fr.uv.y46` iM _ G , -2- resources of any construction related temporary wetland losses or fishery habitat alternations. 7. If, after avoidance and minimization of wetland involvement, the selected alternative requires unavoidable wetland losses, the EIS should provide a mitigation plan to compensate !or wetlands lost. Unless compensation for wetland losses is incorporated as a part of the project, we will likely recommend against the issuance of a Corps of Engineers' Section 10/404 permit for the project. 8. The Cape Fear River supports a population of the endangered shortnose sturgeon (Acipenser brevirostrum) for which we are responsible. Accordingly, you should contact Dr. Terry Henwood of our endangered species staff at Protected Species Management Branch, National Marine Fisheries Service, Southeast Regional Office, 9450 Koger Boulevard, St. Petersburg, Florida 33702, telephone number 813/893-3503. The North Carolina Division of Marine Fisheries is an excellent and reliable source of data concerning specific fishery resources in the project area. A representative of our Beaufort field office is available to discuss National Marine Fisheries Service concerns at any time during this process. Z Sinc Y our , 4? 04 An eas Mager, .

Youngbluth District Engineer U.S. Army Corps of Engineers P.O. Box 1890 Wilmington, North Carolina 28402-1890 Attention: Scott McLendon, Regulatory Branch Dear Colonel Youngbluth: This is the report of the U.S. Fish and Wildlife Service (Se•rvice) on Public Notice (PN) ID #199403552, dated February 27, 1997. The North Carolina Department of Transportation (NCDOT) has applied for a ,Department of the Army (DOA) permit to fill jurisdictional wetlands in conjunction with the construction off a portion of the Wilmington Bypass, New Hanover County, North Carolina (TIP No. R-2633C). The PN states that two alternatives are under consideration and that wetland losses are estimated to range from 130 acres (Southern ?alternative) to 116 acres (Central Alternative). The PN requests comments on these alternatives. This report is submitted in accordance with the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d), and Section 7 of the Endangered Species Act (ESA) of 1973, as amended (16 U:S.C. 1531-1543). It is to be used in your determination of compliance with the Environmental Protection Agency's 404(b) (1) Guidelines (40 CFR 230) and in your public interest review (33 CFR 320.4) as they relate to protection of fish and wildlife resources. According to information provided in the PN, to construct a four-lane, divided freeway on new location. Both build alternatives would interchanges at US 421, US 117/NC133, and I- alternatives would require a new bridge•..over Fear River. the NCDOT proposes about 7.8 miles of provide 40. Both build the Northeast Cape The wetlands in the project area represent very valuable fish and wildlife habitat. The proposed project would produce permanent losses of tidal freshwater marsh, tidal cypress-gum swamp, pocosin wetlands, freshwater bottomland hardwood forest, and wet pine flatwoods. The Service strongly recommends that the District Engineer ensure that this project does not result in any loss of the many functions and values provided by the wetlands in the project area, especially the riverine areas adjacent to the Northeast Cape Fear River. We are concerned that the alternative as currently designed have not incorporated all practical measures to avoid and minimize wetland impacts. Unavoidable losses should be mitigated to ensure that there is no net loss of the functions and values provided by these wetlands. The PN states that the NCDOT is investigating mitigation opportunities in the project area. However, a mitigation proposal is not ready at this time. The Service has stated in previous comments on NCDOT projects that compensatory mitigation should be developed early in the planning process. The complete absence of a compensatory mitigation plan precludes any .realistic assessment of the long-term impacts of the project on fish and wildlife resources. The Service provided _vour office with the comments of the Department of Interior, dated February 24, 1997, on potential project impacts on Lederally protected species based on information contained in the Supplemental Environmental Statement released in December 1996. The Service requestimpact ed d that additional justification was required to support a determination that the project was not likely to adversely affect the rough- leaved loosestrife (L_vsimachia asr)erulaefolia) and Coole.y's meadowrue (Thalictrum coole_yi). Therefore, the requirements of Section 7 of the ESA have not been fulfilled at this time. In summary, the Service believes that the proposed activities I will have a significant anti irreversible adverse impact on fish and wildlife resources. We feel that the NCDOT has inadequately addressed avoidance and minimization measures recommended by the Service in previous comments on NCDOT projects. in the absence of a revised alternative which would truly avoid and minimize wetland impacts, the Service would recommend denial of a permit for this project. The above findings and recommendations constitute the report of the Service. In accordance with the ` procedural requirements of the 1992 404(q)'•Memorandum of I Agreement, Part !V.3(a), we are advising you that the proposed work may result in substantial and unacceptable impact) to aauatic resources of national importance. The Service appreciates the opportunity to comment on this public notice. Please advise us of any action taken by the Wilmington District, Corps of Engineers on this permit application.

Federal Highway Administration 310 New Bern Avenue, Suite 410 Raleigh, NC 27601 Dear Mr. Graf: FB ? R /99" ', C ` /?' 7 LI 1. 2L?f w,I v? s? .7 The Department of the Interior has reviewed the Supplemental Draft Environmental Impact Statement (DEIS) for the Wilmington Bypass, I- 40 to US-421 in New Hanover County, NC, as requested. The Fish and Wildlife Service (FWS) comments in this letter are provided in accordance with the Fish and Wildlife Coordination Act, as amended, (16 USC 661-667d) and Sec. 7 of the Endangered Species Act of 1973, as amended, .(16 USC 1531-1543). The Department's comments on the DEIS for this project dated April 21, 1995, expressed concern that the overall Wilmington Bypass had been divided into three segments. While each segment would have a certain independent utility, the construction of a single segment would dictate, to some degree, the alignment of other segments. The construction of a single segment could serve as a justification for the construction of other segments. While the FWS concurred with an interagency agreement to resolve the segmentation issue by the concurrent release of separate National Environmental Policy Act (NEPA) documents for the central and western sections of the bypass, we believe that the three sections of the bypass are interdependent and that a review of the overall bypass project would have been facilitated by the preparation of a single NEPA document. The wetlands in the project area represent very valuable fish and wildlife habitat. The proposed project would produce permanent losses of tidal freshwater marsh, tidal cypress gum swamp, pocosin wetlands, freshwater bottom land hardwood forest, and wet pine flatwoods. We believe that every effort should be made to avoid and minimize the permanent loss of these wetland areas, including the bridging of all riparian wetlands. If unavoidable losses occur, there should be sufficient compensation to ensure that there is no net loss of the functions and values provided by these wetlands. I Analysis of Alternatives The SDEIS states (p. 2-15) that the western terminus of the project would be I-40. There would be an interchange at the junction with I-40. The document notes (p. 2-15) that the project termini "at I- 40 and US 421 are logical endpoints." However, a statement which appears to occur only in the summary section (p. S-2) states that a "5,800-foot extension east of I-40 is necessary to completely develop the interchange movements." Exhibit 8 of the Natural Systems Technical Memorandum (NSTM), dated October 1996, shows the eastern end of this extension in a wetland area. We question the need for any interchange development to extend 1.1 mile from I-40 and whether the eastern end of this extension represents a true "logical terminus" for transportation purposes between US 421 and I-40. The issue of termini for this project "concerns us because there will be a desire to link adjacent sections of the project to these points. Any work east of I-40 would restrict the alignment of the segment which will be built from US 17 to I-40 (TIP No. R-2405). Our comment on the 1995 DEIS noted that the upgrading of Sidbury Road was an alternative to the new location corridors proposed by the NCDOT. ' We recommend that the Final Environmental Impact Statement (FEIS) fully explain the need for this 1.1-mile extension and support the eastern end of the"extension as a logical terminus for this project. We also recommend that the FEIS specifically address the utility of the 1.1 mile extension in the event that R- 2405 is not build or is designed to meet I-40 either north or south of the interchange proposed for this project. In reference to the other parts of the Wilmington Bypass, the SDEIS notes (p. 2-15) that the two alternatives for this project would "not restrict consideration of other alternatives." We disagree with this statement. Any significant extension of the present project on new location to the east of I-40 would seem to severely restrict the range of alternatives which would be feasible for R- 2405, and would enhance the selection of a new location corridor for the eastern portion of the overall Wilmington Bypass. Figure 2.3 indicates that the eastern terminus of R-2633C will join R-2405 and the western terminus of R-2633C will join R-2633A/B. The overall goal of the project is to construct a single route to join US 17 northeast and southwest of Wilmington. We believe that current plans to connect these three segments will result in the central segment, the subject of this SDEIS, controlling, to some extent, the corridors of the eastern and western parts. The SDEIS presents two alternatives, the southern and center alternatives. Section 2 presents a detailed analysis of the selection and justification of these alternatives. The document 2 does not give a preference between the alternatives. In the narrow context of the single project considered in this SDEIS, the FWS attended interagency meetings which worked to develop alternatives for the central part of the overall bypass. We believe that the analysis which led to the corridors between US 421 and I-40 is adequate. The FWS would like to provide comments on the final design features and eventual alignment on the highway within the corridor selected. We strongly recommend that the final design include features to ensure that the project does not disrupt hydrological flow within the project area. Furthermore, we recommend that the final design includes measures to allow the passage of amphibians, reptiles, and small mammals. Wetland Losses and Mitigation Section 3 presents a comprehensive discussion of the social and natural environmental features of the project area. Table 3-13 (pp. 3-51/52) presents an outline of the biotic communities which would be impacted by the project. The total wetland impacts, based on a 300-foot right-of-way, -would be 133 and 118 acres for the southern and center alternative, respectively. The FWS is especially concerned that both alternatives would pass through the proposed 2,800-acre conservation area along the Northeast Cape Fear River. As noted in the SDEIS (p. 3-63), this area consists of wetlands, bluffs, and buffer strips on both sides of the river. Under the 404(b)(1) guidelines of the Environmental Protection Agency, we understand that the NCDOT should first endeavor to avoid, then minimize, and finally compensate for wetland losses of the project. The SDEIS discusses (p. 4-61) "potential measures to reduce impacts to wetlands." However, the document does not state which, if any, measures will actually be used for the project. While noting that bridging of the wetland along the Northeast Cape Fear River would reduce wetland impacts, the NCDOT has apparently only given "consideration" to this design feature. We recommend that all feasible design features and construction techniques be employed to minimize the permanent loss of wetlands. These measures would include, at a minimum, steeper side slopes for fill, the elimination of lateral drainage ditches, reduced median widths through wetlands, and the bridging of riparian wetlands along the Northeast Cape Fear River. Despite all efforts for avoidance and minimization, this project is ` likely to result in some permanent wetland losses. However, the SDEIS does not present a fully developed I plan for compensatory mitigation. The document indicates (p. 4-61) that a potential mitigation site would be areas within a 2,800-acre tract along the Northeast Cape Fear River which has been proposed as a conservation area by the Wilmington District of the U. S. Army Corps of ' Engineer. The FWS recognizes the high value of this area, but we 3 are concerned that compensation within this area may involve the purchase of relatively undisturbed wetlands which could, in time, be purchased by the Corps. The preservation of this area has been designated as a separate fish and wildlife enhancement feature of the Corps' dredging projects associated with the Wilmington Harbor ship channel, and the Corps' proposal calls for the area to be used for conservation purposes. Therefore, the FWS is concerned that the use of parts of this tract by the NCDOT as compensation could lead to a situation where two agencies were seeking to use the same land in conjunction with two different projects. Furthermore, compensatory mitigation within this area may rely exclusively The the preservation of loabout relatively compensatorydmitigation plan FWS would have reservations which relied entirely on preservation. We strongly encourage locating disturbed and/degraded wetlands along the lower Northeast Cape Fear River which could be restored and/or enhanced. While preservation of existing wetlands can be an important part of a comprehensive plan which is centered on restoration and/or enhancement, the use,.of wetland preservation to oss compensate for the permanent loss of wetlands results areas a n if lose of the functions and values provided by project will result in a net lossn of wetland functions and values, this loss should the FEIS.

Northeast Cape Fear River water resources development project. The FWS believes that impacts to this area should be minimized to the maximum extent possible and recommends a series of methods to reduce these impacts. The DEIS presents an adequate discussion of potential impacts to federally-listed species. The FWS is pleased that field searches were made for the red-cockaded woodpecker (Plcoldes borealle). Based on information in the DEIS, the FWS concurs that the project is not likely to affect federally-listed endangered or threatened species. The FWS, however, believes that it would be prudent for the NCDOT to consider the 14 candidate species for Federal listing in project planning, and we strongly encourage NCDOT.to address this issue in the FEIS. The FWS concerns related to wetland losses and secondary and cumulative impacts of this project are substantial. Depending on the proposal included in the FEIS, the FWS may recommend referring this project to the Council on Environmental Quality under Section 1500 of the Council's Regulations for Implementing the Procedural Provisions of the National Environmental Policy Act. We do, however, wish to coordinate fully at the earliest possible time and avoid any delays in addressing transportation needs for this area, and preclude the necessity for referral.

The National Park Service (NPS) indicates that the DAIS provides an excellent evaluation of the impact of alternatives on historic and archeological sites. The NPS indicates that neither the Southern Preferred Alternative or the Northern Alternative will impact the Thornbury and Nesses Creek Plantation Archeological Districts. The NPS also notes that there are no prehistoric sites identified which would be affected by the Southern Alternative and that four sites may be eligible for the National Register of Historic Places. In correspondence included in the DEIS, the North Carolina State Historic Preservation Officer I (SHPO) indicates that these sites may be salvaged and are not site-significant. The NPS notes that the crossing of the Northeast Cape Fear River has potential with either construction alternative to impact underwater archeological sites. However, the NCDOT agrees to an underwater archeological survey on the selected alternative. Therefore, based on the information presented in the DEIS including correspondence from the SHPO, the MPS agrees with the determination in the DSIS that there are no Section 4(f) involvements with historic and archeological sites. The DSIS does not identify that any recreational sites will be impacted for Section 4(f) or Section 6(f) involvements. 9PICIFIC Comms Aa;lvsis of the Alteriyives and the Selection of Preferred Alternative. paces 2-2 to 2-22 ' The DEIS presents an extensive discussion of the development of alternative routes. The DSIS describes the process by which the 36 preliminary alternatives were reduced to two final alternatives, a Northern and Southern Alternative. The ' NCDOT has selected the Southern Alternative as the preferred route. The FWS is very concerned about the selection of the Southern Alternative for this section of Wilmington Bypass as it relates to the alignment of the other segments. The Wilmington Bypass, as currently conceived, would have three ' sections which are from northeast to southwest: (1) the link from US 17 to I-40 (TIP No. R-2405) ; (2) the segment under current review from I-40 to US 412 (TIP I i No- R-2633C) ; and, (3) the se 3 Bishop. eecauae the termi 9mant from US 421 to rejoin US 17 near the Town of segment already constructed 1 of future eegmentt must join the termini of an have a significant cant influence one construction of the central sa the routes of the other two segment first xi11 I gments.

The . he FW9 s Wetland Losses Aa¢ Mitigation. Duaaee 3-43 to 3-48 and-4.51 to 4.54 The proposed segment of the Wilmington Bypass will impact important wetlands. It is indicated in Table 3.13 that based on the 300-foot right-of-way, the Preferred Southern Alternative would impact 178 acres of wetlands, a total of 62 percent of the area impacted. The highest wetlands impact would occur in pond pine forests (101 acres), bottomland hardwoods (31 acres), and mixed Hardwoods (18 acres), the BWS recognizes that these losses are less than those associated with the Northern Alternative, which would impact 199 wetland acres. Based on a consideration of only the final two build alternatives, the preferred Southern Route apparently would result in less wetlands impact. wetlands' losses could be further reduced by using the above-described design and construction techniques and by employing mitigation in the context of the Council on Environmental Quality's National Environmental Policy Act regulations. Despite design and construction features to avoid and minimize wetland losses, it is indicated that some unavoidable wetland losses will occur and compensatory mitigation will be required. The FWS recommends that the lead agency include a wetland mitigation plan for unavoidable wetlands losses, including direct, indirect, and cumulative losses, associated with the project in the PEIS.. The PWS will evaluate this plan in accordance with our Mitigation Policy which considers the Resource Categories of wetlands impacted. This plan, at a minimum, must include the following parts: - A. the amount (in acres) and a measure of the habitat value for each typo of wetlands lost based on the National Wetlands Inventory/Cowardin classification system; b. the proposed mitigation for each wetland type: either in-kind or out-of- kind; C. the amount (in acres) of each community type to be used for compensatory wetlands; d. the location of areas to ba used for compensation wetlands; e. the present use, condition, and wetland jurisdictional status of areas to be used for compensation wetlands; f. the disposition of compensation wetlands (i.e., who will own, manage, and protect the compensation wetlands in perpetuity) ; g. a work plan which details the initial procedures which will be used to change the present condition of each type of compensation area into a given wetland type lost during construction (i.e., land clearing plans, site preparation, species to be planted, ate.) ; h. a mitigation schedule which givae a timeframe for several intermediate goals and a final goal for the conversion of each area used for compensation to the desired functional wetland; and, a contingency plan which will state the actions to be taken if the goals of the mitigation schedule are not achieved. Regarding the location of compensatory wetlands, the PWS considers areas in the immediate vicinity of the wetlands loot to be preferable to off-site compensation. The issue of replacing habitat value rather than simply replacing loot acreage should be addressed in the mitigation plan.

These comments are provided in accordance with provisions of the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e) and Section 7 of Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543). The U.S. Fish and Wildlife Service (Service) is particularly concerned about potential impacts of the proposed project upon stream ecosystems and associated wetlands within the study corridor. At least eight stream and wetland crossings are present in the study corridor. Special care should be exercised in the design and implementation of all stream crossing structures. The attached pages identify the Federally-listed endangered (E) and threatened (T) species which may occur in the proposed project corridor. If the proposed project will be removing pines greater than or equal to 30 years of age in pine or pine/hardwood habitat, surveys should be conducted for active red-cockaded woodpecker cavity trees in appropriate habitat within a 1/2 mile radius of project boundaries. If red-cockaded woodpeckers are observed within the project area or active cavity trees found, the project has the potential to adversely affect the red-cockaded woodpecker and you should contact this office for further information. The service's review of any environmental document would be greatly facilitated if it contained the following information: 1) A description of the fishery and wildlife resources within existing and required additional right-of-way and any areas, such as borrow areas, which may be affected directly or indirectly by the proposed improvements. 2) Acreage of branches, creeks, streams, rivers or wetlands to be filled. Wetlands affected by the proposed project should be mapped in accordance with the Federal Manual for Identifying and Delineating Jurisdictional Wetlands. 3) Linear feet of any water courses relocated. 4) Acreage of upland habitats, by cover type, which would be eliminated. 5) Techniques which will be employed for designing and constructing any relocated stream channels or for creating replacement wetlands. 6) Mitigation measures which will be employed to avoid, eliminate, reduce or compensate for habitat value losses associated with any of the proposed improvements. 7) Assessments of the expected secondary and cumulative impacts of the proposed project on fish and wildlife resources. • Sincerely yours, L.K.

Youngbluth District Engineer, Wilmington District Department of the Army, Corps of Engineers P. O. Box 1890 Wilmington, North Carolina 28402-1890 Attention Scott McLendon Dear Colonel Youngbluth: In accordance with Part IV, Section 3(a) of the current Memorandum of Agreement (MOA) between the Departments of Commerce and the Army, I am notifying you of the National Marine Fisheries Service's (NMFS) intent to consider referral of Department of the Army (DOA) permit application 199403552 dated February 27, 1997. At issue is the request by the North Carolina Department of Transportation (NCDOT) to place fill material in waters and wetlands adjacent to the Northeast Cape Fear River, Ness Creek, and other unnamed tributaries of the Northeast Cape Fear River to construct the Wilmington Bypass north of Wilmington, New Hanover County, North Carolina. This letter details reasons: (1) why there may be substantial and unacceptable adverse impacts to aquatic resources of national importance; and (2) why issuance of the specified permit must be conditioned or denied to protect these resources. The proposed project consists of the construction of 7.8 miles of 4-lane median divided freeway from east of I-40 to US 421 west of the Northeast Cape Fear River. The typical cross section includes a 46-foot-wide grassed median. A high rise bridge with a 65 foot vertical clearance will be constructed over the Northeast Cape Fear River. The Draft Environmental Impact Statement (DEIS) which was circulated in January 1995 described two alternative alignments for the highway, a Southern Alternative and a Northern Alternative. A Supplemental Draft Environmental Impact Statement (SDEIS), which addressed a new Central Alternative, was circulated for review in December 1996. Based on substantial adverse impacts to natural and cultural resources, the Northern Alternative was eliminated from further consideration in April 1996. 1 t Wetlands impacted by the project include a mixture of bottomland hardwoods, tidal, fresh, and saltwater marsh, tidal cypress and gum swamp, pocosin, and wet pine flats. Total wetland impacts would be 130 acres and 116 acres of wetlands for the Southern and Central alternatives, respectively. 0 Pnnled oaf Recycled P-111- t 7 'IV Weiland species commonly found in the project area include bald cypress (Taxodium distichum), tupelo gum (Nvssa Aggatica), black: gum (Nvssa UIvatica), green ash C -.anus aennsvlvanica), swamp black gum vssa svi?vatica), sweet gum (LiQUidambar styraciflua), loblolly pine (Pinus taeda), wax myrtle erica cerifera), cattail (Typha sp.), soft rush (Juncus effusus), and saw grass (Cladium iamaicense). These wetlands perfoR as maintenance fun UonsniWfunctions etlands adjacentgto providing uplands function ?o aquatic species and water quality slow storm water run-off and trap excessive sediments, nutrients, and pollutants before they can reach surface waters, thereby, aiding in the maintenance of water quality.' By removing excessive sediments, nutrients, and pollutants from adjacent waters during periods of seasonal flooding, seasonally and tidally flooded wooded wetlands and marshes also function to maintain water quality in the Northeast Cape Fear River.' These wetlands are also a source of primary productivity and provide a source of detritus, an important component in the aquatic food chain supporting fishery resources. When flooded these wetlands also provide important nursery area functions for a host of estuarine dependent and anadromous fish and shellfish.' The Northeast Cape Fear River and its tributaries and adjacent wetlands, including portions of the project area, have been designated as primary nursery areas (PNA) by the North Carolina Division of Marine Fisheries. PNAs are defined as those ,areas in which, for reasons such as food, cover, bottom type, salinity, temperature, and other factors, young finfish and crustaceans spend the major portion of their initial growing season.' This designation reemphasizes the importance of these wetlands-to the continued production of fishery resources. Commercially and recreationally important, fishery resources found in the project area include estuarine dependent species such as spot (Leiostomus xanthurus), flounders (Paralichthvs spp.), Atlantic croaker (Mcrooogonias undulatus), striped mullet (Mugil cephalus), shrimp enaeus spp.), and blue crab (Callinectes sa idus . These species are identified in Section 906(e)(1) of the Water Resources Development Act of 1986 (PL 99-602) as species of "national economic importance". A fishery management plan (FMP) for shrimp has been developed by the South Atlantic Fishery Management Council (SAFMC) because shrimp stocks are reduced. Additionally, the Mid-Atlantic Fishery Management Council, in cooperation with the SAFMC, has developed FMPs for summer flounder. The FMP for shrimp and flounder specify rigorous management and protection of the managed species and their essential habitat. INC Coastal Nonpoint Pollution Control Program. 1995.

Anadromous fishery resources are dependent on hardwood swamps for annual pulses of detritus which form the basis of complex food webs that support fish productivity in the ecological system.' In recent years, landings of these important species have declined which has been attributed to declines in water quality and losses of habitat.6 Under the Atlantic Coastal Fisheries Cooperative Management Act of 1993, the Atlantic States Marine Fisheries Commission is developing management plans for these species which include protection of managed species and their essential habitats. Accordingly, we regard these fishery resources and their associated habitat as aquatic resources of "national economic importance". The NMFS has been involved with this project since its onset in 1989, including on-site inspections, interagency meetings, and the review of the DEIS and SDEIS. Based on this involvement, we believe that the wetland losses associated with either alternative will be detrimental to NMFS trust resources. However, we believe that the Center Alternative is environmentally preferable to the Southern Alternative since the overall wetland losses are less with the Center Alternative and it includes bridging of all wetlands located adjacent to the Northeast Cape Fear River. The Southern Alternative is totally unacceptable since it does not bridge rivetine wetlands and involves the loss of more wetland acreage. Even.though this project has been in the planning stage for a considerable time, there remains many issues that must be resolved before the NMFS can recommend authorization for this work. The goals of wetland avoidance and impact minimization, as well as provisions for adequate mitigation for unavoidable wetland losses, must be achieved prior to federal authorization for this work. To accomplish these goals the following criteria or standards must be met: 1. All riverine wetlands must be bridged with bridge design and construction techniques being selected to minimize impacts to wetlands and fishery resources. Impacts associated with construction techniques are of great concern to the NMFS in areas which support an annual anadromous fish migration. The use of construction techniques which minimize impacts to fisheries is essential for agreement on federal authorization by the NMFS. 17. Primary nursery areas must be protected from discharges of storm water run-old bod. temporary and permanent, as well as, other pollutants associated with highway and bridge construction. 3. Seasonal work restrictions protecting anadromous fishery resources, which include the I 5IMeeter, D.A., &J. Livingston, and G.C. Woodsum. 1979. Long term climatological cycles and population changes in a river-dominated estuarine system. pp. 315-338. In R.J. Livingston (ed.) Ecological Processes in Coastal and Marine Systems. Plenum Press. New York, New York. 6E eri pp y, S.P. and S.W. Ross. 1986. Characterization of the North Carolina Pamlico- Albemarle Estuarine Complex. NOAA Technical Memorandum NTIFS-SEFC-175. E endangered shortnose sturgeon (Acipenser brevirostrum), must be in place and strictly adhered to. Since the shortnose sturgeon is a likely inhabitant in the Cape Fear River system, in `nccordance with the Endangered Species Act of 1973, as amended, it is the responsibility of the appropriate federal regulatory agency to review its activities and programs and to identify any activity or programs that may affect endangered or threatened species or their habitat. Due to the possible presence of protected species, consultation with our Protected Species Management Branch at the letterhead address, must be initiated. If it is determined that these activities may adversely affect any species listed as endangered or threatened, then formal consultation is required. To date, we have no record of any coordination or consultation with our Protected Species Management Branch. 4. An acceptable mitigation plan to compensate for unavoidable wetland losses must be an integral part of the project plans. Any mitigation proposed must be in accordance with the 1990 MCA Between the Environmental Protection Agency and the DOA concerning the Determination of Mitigation Under the Clean Water Act Section 404 (b)(1) Guidelines. As currently proposed, neither alternative has demonstrated compliance with this MOA in the areas of wetland avoidance and impact minimization. The SDEIS addressed a mitigation plan consisting of the purchase of 2,300 acres of wetlands located on both sides of the Northeast'Cape Fear River north of Wilmington, North Carolina. This plan is almost totally preservation of existing wetlands. While the proposed preservation area could be a component of a mitigation plan, preservation alone is unacceptable to the NMFS as a total mitigation package. At a minimum, adequate wetland mitigation must provide a 1:1 replacement ratio, in-kind and in the same river basin as that of the losses. The public notice does not address the cumulative impacts associated with this, along with approximately 12 other highway projects in the Cape Fear River Basin. We believe that a formal accounting of NCDOT's overall impacts on this area is necessary for future planning in the area of impact mitigation. Based on the above, the NMFS believes that the Center Alternative will have the least impact on I MFS trust resources. However, there are unresolved issues which must be addressed before this work will be acceptable to the NMFS. Therefore, we recommend that federal authorization of this work not be granted. We appreciate the opportunity to provide these comments.
