sewer line is being modified.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
Repair breached dam and install a new inlet and outlet structure with newwing walls. The project will include grading within the original pond footprint.
A portion of an existing sewer line runs parallel to Hybarts Branch. This portion of the sewer will be abandoned and replaced with a larger diameter pipe away from the stream. Standard
construction equipment will be used; bulldozer, backhoe, dump truck, and cranes. Wetland impact will result from the sewer work.

E. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
Dam safety requested all utilities in the dam be moved away from the limits of the dam at least one half the height of the mapmum dam height. This
forced the sewer into the footprint of Wetland B. The sewer Will cross the wetland at its narrowest point.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
There is only a 10' construction access on either side of the sewer easement to minimize wetland impacts. The majority of the open water impacts are
temporary.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
r Yes r No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
The project's total permanent impacts (0.002 acres of wetland, 70 linear feet of stream, and 0.06 acre of open water) are belowthe 0.1 acre wetland threshold and 150 linear foot
stream threshold for mitigation under NWPs 3 and 12.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
1. Diffuse Flow Plan
1a. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?
