Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Coleco H. Sullins, Director Division of Water Quality July 2, 2007 TO: Hank Schwab, Bridge Project Planning Engineer, NCDOT FROM: Polly Lespinasse, NC Division of Water Quality, Mooresville Regional Office SUBJECT: Scoping Review of NCDOT's Proposed Bridge Replacement Projects: B- 4517 and 6- 4519, Gaston County In reply to your correspondence dated June 6, 2007 (received June 12, 2007) in which you requested comments for the above referenced projects, the NC Division of Water Quality (DWQ) offers the following comments: Project Specific Comments B-4517, Bridge No. 49 Over Crowders Creek, Gaston County Crowders Creek is a Class C; 303(d) waters of the State. Crowders Creek is on the 303(d) list for impaired use for aquatic life due to impaired biological integrity. DWQ is very concerned with sediment and erosion impacts that could result from this project. DWQ recommends that the most protective sediment and erosion control BMPs be implemented to reduce the risk of nutrient runoff to Crowders Creek. DWQ requests that road design plans provide treatment of the storm water runoff through best management practices as detailed in the most recent version of NC DWQ Stormwater Best Management Practices. B-4519, Bridge 155 Over Little Long Creek, Gaston County Little Long Creek is Class C, 303(d) Waters of the State. Little Long Creek is on the 303(d) list for impaired use for aquatic life due to urban runoff (historical listing). DWQ is very concerned with sediment and erosion impacts that could result from this project. DWQ recommends that the most protective sediment and erosion control BMPs be implemented to reduce the risk of nutrient runoff to Little Long Creek. DWQ requests that road design plans provide treatment of the storm water runoff through best management practices as detailed in the most recent version of NC DWQ Storm Water Best Management Practices. General Comments Regarding Bridge Replacement Projects DWQ is very concerned with sediment and erosion impacts that could result from this project. North Carolina Department of Transportation (NCDOT) shall address these concerns by describing the potential impacts that may occur to the aquatic environments and any mitigating factors that would reduce the impacts. If foundation test borings are necessary; it shall be noted in the document. Geotechnical work is approved under General 401 Certification Number 3494/Nationwide Permit No. 6 for Survey Activities.

If a bridge is being replaced with a hydraulic conveyance other than another bridge, DWQ believes the use of a Nationwide Permit may be required. Please contact the US Army Corp of Engineers to determine the required permit(s). 4. If the old bridge is removed, no discharge of bridge material into surface waters is allowed unless otherwise authorized by the US ACOE. Strict adherence to the Corps of Engineers guidelines for bridge demolition will be a condition of the 401 Water Quality Certification. Whenever possible, the DWQ prefers spanning structures. Spanning structures usually do not require work within the stream or grubbing of the stream banks and do not require stream channel realignment. The horizontal and vertical clearances provided by bridges allow for human and wildlife passage beneath the structure, do not block fish passage and do not block navigation by canoeists and boaters. Bridge deck drains shall not discharge directly into the stream. Stormwater shall be directed across the bridge and pre-treated through site-appropriate means (grassed swales, pre-formed scour holes, vegetated buffers, etc.) before entering the stream. Please refer to the most current version of NC DWQ Stormwater Best Management Practices. If concrete is used during construction, a dry work area shall be maintained to prevent direct contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete shall not be discharged to surface waters due to the potential for elevated pH and possible aquatic life and fish kills. 8. Bridge supports (bents) shall not be placed in the stream when possible. If temporary access roads or detours are constructed, the site shall be graded to its preconstruction contours and elevations. Disturbed areas shall be seeded or mulched to stabilize the soil and appropriate native woody species shall be planted. When using temporary structures the area shall be cleared but not grubbed. Clearing the area with chain saws, mowers, bush-hogs, or other mechanized equipment and leaving the stumps and root mat intact allows the area to re-vegetate naturally and minimizes soil disturbance. 10. Sediment and erosion control measures sufficient to protect water resources must be implemented and maintained in accordance with the most recent version of North Carolina Sediment and Erosion Control Planning and Design Manual and the most recent version of NCS000250. 11. All work in or adjacent to stream waters shall be conducted in a dry work area unless otherwise approved by NC DWQ. Approved BMP measures from the most current version of NCDOT Construction and Maintenance Activities manual such as sandbags, rock berms, cofferdams and other diversion structures shall be used to prevent excavation in flowing water. 12. Heavy equipment shall be operated from the bank rather than in stream channels in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into streams. This equipment shall be inspected daily and maintained to prevent contamination of surface waters from leaking fuels, lubricants, hydraulic fluids, or other toxic materials. 13. In most cases, the DWQ prefers the replacement of the existing structure at the same location with road closure. If road closure is not feasible, a temporary detour shall be designed and located to avoid wetland impacts, minimize the need for clearing and to avoid destabilizing stream banks. If the structure will be on a new alignment, the old structure shall be removed and the approach fills removed from the 100-year floodplain. Approach fills shall be removed and restored to the natural ground elevation. The area shall be stabilized with grass and planted with native tree species. Tall fescue shall not be used in riparian areas. Mrs Hank Schwab Page Three General Comments if Replacing the Bridge with a Culvert Placement of culverts and other structures in waters, streams, and wetlands shall be below the elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches, and 20 percent of the culvert diameter for culverts having a diameter less than 48 inches, to allow low flow passage of water and aquatic life. Design and placement of culverts and other structures including temporary erosion control measures shall not be conducted in a manner that may result in dis-equilibrium of wetlands or streambeds or banks, adjacent to or upstream and down stream of the above structures. The applicant is required to provide evidence that the equilibrium is being maintained if requested in writing by DWQ. If this condition is unable to be met due to bedrock or other limiting features encountered during construction, please contact the NC DWQ for guidance on how to proceed and to determine whether or not a permit modification will be required. 2. If multiple pipes or barrels are required, they shall be designed to mimic natural stream cross section as closely as possible including pipes or barrels at flood plain elevation and/or sills where appropriate. Widening the stream channel shall be avoided. Stream channel widening at the inlet or outlet end of structures typically decreases water velocity causing sediment deposition that requires increased maintenance and disrupts aquatic life passage. 3. Riprap shall not be placed in the active thalweg channel or placed in the streambed in a manner that precludes aquatic life passage. Bioengineering boulders or structures shall be properly designed, sized and installed. Thank you for requesting our input at this time. The DOT is reminded that issuance of a 401 Water Quality Certification requires that appropriate measures be instituted to ensure that water quality standards are met and designated uses are not degraded or lost. If you have any questions or require additional information, please contact Polly Lespinasse at (704) 663-1699. cc: Steve Lund, US Army Corps of Engineers, Asheville Field Office Ron Lucas, Federal Highway Administration Chris Militscher, Environmental Protection Agency Marla Chambers, NC Wildlife Resources Commission Marella Buncick, US Fish and Wildlife Service Sonia Gregory, DWQ Central Regional Office File Copy ..'j W A rF9Q co ?rm V-N\ v MEMORANDUM Michael F_ Easley, Governor William G.

'a I NATURAL RESOURCES TECHNICAL REPORT EXECUTIVE SUMMARY Replacement of Bridge No. 49 SR 1103 over Crowder's Creek Gaston County, North Carolina (B-4517) (State Project No. 8.2812901) (Federal Aid No. BRSTP-1103(15)) Prepared for: The North Carolina Department of Transportation Raleigh, North Carolina June 2007 r e The N.C. Department of Transportation (NCDOT) proposes to replace Bridge No. 49 located on North Carolina State Road 1103 (SR 1103) over Crowder's Creek in Gaston County, North Carolina (Figure 1). INTRODUCTION The project study area is located at the crossing of SR 1103 over Crowder's Creek (Figure 1). The project study area has been determined to be approximately 400 feet wide, centered on SR 1103, and approximately 1200 feet long. The project study area encompasses approximately 11.9 acres (Figure 2). Elevations within the project study area range from a high of approximately 720 feet National Geodetic Vertical Datum (NGVD) to a low of approximately 640 feet NGVD (USGS Gastonia South, NC 7.5-minute topographic quadrangle [1993]) within the stream channel. Land uses within and adjacent to the project study area consist of woodlands, sewer and power easements, and roadside shoulders. Based on soil mapping for Gaston County (NRCS 1997a), the project study area is underlain by four soil series: Appling (Typic Kanhapludults), Chewacla (Fluvaquentic Dystrochrepts), Congaree (Typic UdiFluvents), and Madison (Typic Kanhapludults). These soil series are considered non-hydric in Gaston County, but the Chewacla and Congaree series may contain inclusions of hydric soils (NRCS 1997b). Three alternatives have been proposed for the replacement of Bridge No. 49. Alternate A proposes that Bridge No. 49 be replaced at its current location while maintaining traffic with an off-site detour. Alternate B proposes that Bridge No. 49 be replaced at its current location while maintaining traffic with an on-site detour over a temporary bridge south of the existing bridge. Alternate C proposes that Bridge No. 49 be replaced at a new location south of the existing bridge while maintaining traffic over the existing bridge. PHYSICAL CHARACTERISTICS Water Resources The project study area is located within sub-basin 03-08-37 of the Catawba River Basin (NCDWQ 2004). This area is part of USGS Hydrologic Unit 03050101 (Seaber et al. 1987) of the South Atlantic-Gulf Region. The project study area contains three streams: Crowder's Creek, and two unnamed tributaries (UT) to Crowder's Creek (UT1 and UT2) (Figure 2). The structure targeted for replacement spans Crowder's Creek. Crowder's Creek, from its source to the Yadkin River, has been assigned Stream Index Number 11-135 NCDWQ (NCDWQ 2006b). A Best Usage Classification of C has been assigned to Crowder's Creek. Class C waters are suitable for secondary recreation, aquatic life propagation and survival, fishing, wildlife, and agriculture. Secondary recreation includes wading, boating, and other uses not involving human body contact with waters on an organized or frequent basis. No other stream classifications have been assigned to Crowder's Creek. No High Quality Waters (HQW), Outstanding Resource Waters (ORW), Water Supply I (WS-1), Water Supply 11 (WS-11), or watershed Critical Areas (CA) occur within 1.0 mile of the project study area (NCDWQ 2006b). Crowder's Creek from its source to the South Carolina border, including the reach within the project study area,'is listed on the N.C. 2006 final Section 303(d) list for urban runoff and storm sewers (NCDWQ 2006c). Biotic Resources Three distinct plant communities were identified within the project study area: bottomland hardwood forest, disturbed/maintained land, and Mesic Mixed Hardwood Forest (Piedmont Subtype) (Figure 2). Table 1 shows the acreage of each community within the project study area and each community. In addition to terrestrial communities, approximately 0.6 acre (5 percent) of the project study area encompasses Crowder's Creek, UT1, and UT2, while 0.6 acre (5 percent) includes impermeable surfaces. Table 1: Plant Communities Within the Project Study Area . Plant Community Coverage (Acres) Coverage (Percent) Bottom[ and Hardwood Forest 5.6 47 Disturbed/Maintained Land 2.6 22 Mesic Mixed Hardwood Forest 2.5 21 Total 10.7 90 Proposed alternatives include both permanent and temporary impacts. Permanent impacts are considered to be those impacts that occur within proposed cut-fill limits, and include a 25-foot buffer. Temporary impacts are considered to be those impacts which occur within the cut-fill footprint associated with the temporary detour of Alternate B, and also include a 25-foot buffer. Plant communities within the project study area were delineated to determine the approximate area and location of each (Figure 2). A summary of potential impacts to plant communities is presented in Table 2.

This project may be processed as a Categorical Exclusion (CE) under Federal Highway Administration (FHWA) guidelines. USACE has made available Nationwide Permit (NWP) 23 (67 FR 2020, 2082; January 15, 2002) for CEs due to minimal impacts to waters of the United States expected with bridge construction. NCDWQ has made available a General 401 Water Quality Certification for NWP 23 (GC 3403). If temporary structures are necessary for construction activities, access fills, or dewatering of the site, then a NWP 33 (67 FR 2020, 2087; January 15, 2002) permit and the associated General 401 Water Quality Certification (GC 3366) will be required. In the event that NWPs 23 and 33 will not suffice, impacts attributed to bridge replacement and associated approach improvements may qualify under General Bridge Permit (GP) 031 issued by the Wilmington USACE District. NCDWQ has made available a General 401 Water' Quality Certification for GP 031 (GC 3404). Notification to the Wilmington USACE District office is required if this general permit is utilized. Protected Species Species with the federal classification of Endangered, Threatened, or officially Proposed for such listing are protected under the Endangered Species Act (ESA) of 1973, as amended (16 U.S.C. 1531 et seq.). The term "Endangered Species" is defined as "any species which is in :I l 'I danger of extinction throughout all or a significant portion of its range;" and the term "Threatened Species" is defined as "any species which is likely to become an Endangered species within the foreseeable future throughout all or a significant portion of its range" (16 U.S.C. 1532. Table 4 lists the three federally protected species for Gaston County as of June 26, 2007 (USFWS 2007). Table 4. Federally Protected Species Listed for Gaston County Common Habitat Biological Conclusion Scientific Name Status' Name Present Bald eagle Haliaeetus leucocephalus T No No Effect Bog turtle Clemmys muhlenbergii T (S/A) No Not Required Schweinitz's E Yes No Effect sunflower Helianthus schweinitzii 'Federal Status: E--Endangered; T-Threatened; T (S/A)-- Threatened due to similarity of appearance Haliaeetus leucocephalus (Bald eagle) Threatened Family: Accipitridae Date Listed: March 11, 1967 BIOLOGICAL CONCLUSION: NO EFFECT The project study area, does not contain suitable nesting, perching, or foraging habitat for bald eagle. There are no natural shorelines or large bodies of water for foraging within 1.0 mile of the project study area. In addition, NCNHP records (reviewed June 26, 2007) document no occurrence of bald eagle within 2.0 miles of the project study area and no individuals were observed during field investigations. Consequently, the proposed project will have "No Effect" on bald eagle. Clemmys muhlenbergii (Bog turtle) Threatened due to Similarity of Appearance Family: Emydidae Date Listed: November 4, 1997 Threatened due to Similarity of Appearance species are not subject to Section 7 consultation and a biological conclusion is not required. However, this project is not expected to affect the bog turtle as' the project study area contains no suitable wetland habitat. NCNHP records (reviewed June 26, 2007) document no occurrence of.the bog turtle within 1.0 mile of the project study area. Based on NCNHP records and lack of suitable habitat, this project will have no effect on the bog turtle. Helianthus schweinitzii (Schweinitz's sunflower) Endangered Family: Asteraceae Date Listed: May 7, 1991 BIOLOGICAL CONCLUSION: NO EFFECT The project area provides habitat preferred by Schweinitz's sunflower within power and sewer easements, along roadsides and upland forest edges. NCNHP records (reviewed June 26, 2007) document no occurrence of Schweinitz's sunflower within 1.0 mile of the project study area, and a systematic plant-by-plant survey along overlapping transects was conducted on October 11, 2006 by ESC biologists revealed no individuals of this species within the project study area. Consequently, the proposed project will have No Effect on Schweinitz's sunflower. Federal Species of Concern - Shoals spiderlily (Hymenocallis coronaria) is the only Federal Species of Concern (FSC) listed by USFWS for Gaston County (USFWS 2007). FSC are not afforded federal protection under the Endangered Species Act of 1973, as amended, and are not subject to any of its provisions, including Section 7,, until they are formally proposed or listed as Threatened or Endangered. Candidate Species - The USFWS list also includes a category of species designated as "Candidate" (C). A species with this designation is one that is a species under consideration for official listing for which there is sufficient information to support listing. One C species is listed for Gaston County: Georgia aster (Aster georgianus) which has a state status of Threatened (Franklin and. Finnegan 2006). Georgia aster populations typically prefer roadsides, woodland borders, dry rocky woods, and disturbed areas such as fields and utility right-of-ways. Suitable habitat exists for this species within the project study area. NCNHP records (reviewed June 26, 2007) list no documentation for Georgia aster within 1.0 mile of the project study area. A systematic survey conducted on October 11, 2006 by ESC biologists revealed no individuals of Georgia aster within the project study area. CONCLUSIONS No Outstanding Resource Waters (ORW), High Quality Waters (HOW), Water Supply I (WS-1), Water Supply II (WS-11) waters, watershed Critical Areas (CA), or Trout Waters Jr) occur within 1.0 mile of the project study area (NCDWQ 2006). Crowder's Creek from its source to the South Carolina border, including the reach within the project study area, is listed on the N.C. 2006 Final Section 303(d) list for urban runoff and storm sewers (NCDWQ 2006c). The project study area contains three jurisdictional surface waters (Crowder's Creek, UT1, and UT2) and two vegetated wetlands (Wetlands 1 and 2). Direct impact to jurisdictional areas is expected from the replacement of Bridge No. 49- This project may be processed as a CE due to minimal impacts to waters of the United States expected with bridge construction. The proposed project is not expected to adversely impact any federally protected species.
