VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. 1'<igc 5 of 8 USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strmizlde.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. A finding of insignificant impact is anticipated; therefore, a mitigation plan is not provided. Cumulative impacts are less than 150 feet. The maximum amount of impact to a single stream is 40 linear feet. No Outstanding Resource Waters, federally protected species or their habitats, or essential fishery habitats occur in the project area. The project is not located in a High Quality Water. 2.

Construction is anticipated to take 4 weeks. 1. Prior to beginning pipe removal and installation, drill holes and place supporting bolts in one end of a single line of 60' long 117" X 79" CM pipe arch. 2. nstall a rock silt dam downstream of the proposed diversion channel outlet to prevent incidental sediment loss from the diversion channel. 3. Dig a diversion channel to dewater the construction area. The diversion channel will be approximately the same width as the existing channel. 4. Line the diversion channel with poly-fabric to prevent sediment loss. 5. Install ABC aggregate or a less intrusive dewatering device to force flow into the diversion channel. 6. Breach the inlet and outlet dams of the diversion channel. 7. Remove one existing line of 40' long 72" CM pipe. 8. Excavate to sufficient depth to allow burial of the pipes to 1', place base stone, and two lines of 60' long 117" X 79" CM pipe arch. 9. Backfill the new lines of pipe and place rip rap only as needed. 10. Prior to removing the diversion place cofferdams to divert flow into the pipe without the sill. 11. Starting from the downstream end, remove the dewatering structure and restore the natural stream contours. 12. Place ABC aggregate at each end of the diversion channel forcing flow through the pipe without the sill. 13. Dewater the diversion channel, backfill with suitable material, and compact the backfilled material. 14. Construct mold and pour concrete sill in the appropriate line of pipe. 15.
