The erosion and sediment control measures for the projecfmust be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual. b. The design, installation, operation, and maintenance of the sediment and.erosion control measures must be such that they equal, or exceed, the requirements. specified in the most recent version of the North Carolina Sediment and Erosion Control, Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the project. c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual. d. The reclamation measures and implementation must comply with the reclamation in accordance with 'the requirements of the Sedimentation Pollution Control Act. 6.: 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 land possible aquatic life and fish kills. 7. The use of rip-rap above the Normal High Water Mark shall be minimized. Any rip-rap placed for stream stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life passage. 8. During the construction of the project, no staging of equipment of any kind is permitted in waters of the U.S., or protected riparian buffers. Page 3 of 5 9. The dimension, pattern and profile of the stream above and below the crossing shall not be modified..:. Disturbed floodplains and streams shall be restored to natural geomorphic conditions 10. Heavy equipment shall be operated from the banks rather than in the stream channel in order to minimize ` sedimentation and reduce the introduction of other pollutants into the stream. 11. All mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. 12. No rock, sand or other materials shall be. dredged from the stream channel except where authorized by this certification. 13. Discharging hydroseed mixtures. and washing out hydroseeders and other equipment in or adjacent to surface , waters is prohibited. 14.

Impacts to areas within the fencing are prohibited unless otherwise authorized by this certification. 15. Native riparian vegetation (ex. list trees and shrubs native to your geographic region) must be reestablished 'within the construction limits of the project by the end of the growing season following "completion of constriction. 16. There shall be no excavation from, or waste disposal into, jurisdictional wetlands or waters associated with this - certification without appropriate modification. Should waste or borrow sites, or access roads to waste or borrow sites, be located in wetlands or streams, compensatory mitigation will be required since that is a direct impact from road construction activities. 17. Strict adherence to the most recent version of NCDOT's Best Management Practices For Bridge Demolition and Removal approved by the US Army Corps of Engineers is a condition of the 401 Water Quality Certification., . . 18.
