In the event that any jurisdictional areas are identified, the Division of Water Resources requests that NCDOT consider the following environmental issues far the proposed project: Project Specif►c Comments: 1. DWR cannot comment on permit requirements with the limited information provided and wide range of estimated impacts within the proposed alternative corridors. A verified field delineation is required to determine the presence or absence of jurisdictional resources within the project limits. In addition, NCDOT State of No�th Carolina IEnvironmental Quality I Water Resources 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Phone:919-807-6300 must provide an estimate of impacts to any resources located within the construction limits of the project befare we can specifically comment on NCDWR permit eligibility. Please be advised that a 401 Water Quality Certification requires satisfactory protection of water quality to ensure that water quality standards are met and no wetland or stream uses are lost. Final permit authorization will require the submittal of a formal application by the NCDOT and written concurrence from NCDWR. Please be aware that any approval will be contingent on appropriate avoidance and minimization of wetland and stream impacts to the maximum extent practical, the development of an acceptable stormwater management plan, and the inclusion of appropriate mitigation plans where appropriate. Review of the project reveals the presence of surface waters classified as B;Sw, High Quality Waters of the State in the project study area. This is one of the liighest classifications for water quality. Provided the project meets the requirements of NCDOT NPDES permit NCS000250, no application for individual State Stormwater permit will be required (Streamlining State Stonnwater Permitting for NCDOT Projects letter, July 26, 2013). General Project Comments: The environmental document should provide a detailed and itemized presentation of the proposed impacts to wetlands and streams with corresponding mapping. If mitigation is necessary as required by l SA NCAC 2H.0506(h), it is preferable to present a conceptual (if not finalized) mitigation plan with the environmental documentation. Appropriate mitigation plans will be required prior to issuance of a 40l Water Quality Certifi cati on. Environmental impact statement alternatives shall consider design criteria that reduce the impacts to streams and wetlands from storm water runofF. These alternatives shall include road designs that allow for tt-eatment of the storm water runoff through best management practices as detailed in the most recent version of NCDWR's Stormwater Best Management Practices Manual, July 2007, such as grassed swales, buffer areas, preformed scour holes, retention basins, etc. After the selection of the preferred alternative and prior to an issuance of the 401 Water Quality Certification, the NCDOT is respectfully reminded that they will need to demonstrate the avoidance and minimization of impacts to wetlands (and streams) to the maximum extent practical. In accordance with the Environmental Mana�ement Commission's Rules (l SA NCAC 2H.0506[h]), mitigation will be required for impacts of �reater than 1 acre to wetlands. In the event that mitigation is required, the mitigation plan shall be designed to replace appropriate lost functions and values. North Carolina Division of Mitigation Services may be available for assistance with wetland mitigation. 7. An analysis of cumulative and secondary impacts anticipated as a result of this project may be required if an alternative on new location is proposed. Tt�e type and detail of analysis shall conform to the NC Division of Water Resource Policy on the assessment of secondary and cumulative impacts dated April l0, 2004. 8. In accardance with the Environmental Management Commission's Rules (l SA NCAC 2H.0506[h]), mitigation will be required for impacts of greater than 150 linear feet to any perennial stream. In the event that mitigation is required, the mitigation plan shall be designed to replace appropriate lost functions and values. The North Carolina Division of Mitigation Services may be available far assistance with stt-eam mitigation. 9. Future documentation, including the 40l Water Quality Certification Application, shall continue to include an itemized listing of the proposed wetland and stream impacts with corresponding mapping. 10. The NCDWR is very concerned with sediment and erosion impacts that could result fi-om this project. The 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. 11. The NCDOT is respectfully reminded that all impacts, including but not limited to, bridging, fill, excavation and clearing, and rip rap to jurisdictional wetlands, streams, and riparian buffers need to be included in the final impact calculations. These impacts, in addition to any construction impacts, temporary or otherwise, also need to be included as part of the 401 Water Quality Certification Application. � 2. Where streams must be crossed, the NCDWR prefers bridges be used in lieu of culverts. However, we realize that economic considerations often require the use of culverts. Please be advised that culverts should be countersunk to allow unimpeded passage by fish and other aquatic organisms. Mareover, in areas where high quality wetlands or streams are impacted, a bridge may prove preferable. When applicable, the NCDOT should not install the bridge bents in the creek, to the maximum extent practicable. 13. 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, floodplain benches, and/or sills may be required where appropriate. Widening the stream channel should 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. l4. The 40l Water Quality Certification application will need to specifically address the proposed methods for stormwater management. More specifically, stormwater shall not be permitted to discharge directly into streams or surface waters. 15. 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 Plannin� and Design Manual and the most recent version of NCS000250. l6. Riparian vegetation (native trees and shrubs) shall be preserved to the maximum extent possible. Riparian vegetation must be reestablished within the construction limits of the project by the end of the growing season following completion of construction Thank you for requesting our input at this time. The NCDOT 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.
