1 a. Does the project include or is it adjacent to protected riparian buffers identified
® Yes In No
within one of the NC Riparian Buffer Protection Rules?
1 b. If yes, then is a diffuse flow plan included? If no, explain why.
Comments: The buffer impacts for this project include the complete removal of
Gauer una �UaEi n -Z putt or Me quarry extension. Ido OufieT irmpacis will occur
Geyontl Me quarry limits, an'a collectea stormwater from Me perimeter Germ will Ge
routed to two wet detention ponds that directly discharge to the unnamed tributary
streams immediately south of Charlie Brooks Road. These ponds will be designed to
meet 90 percent TSS removal and would be designed to discharge at non-erosive
-�claclticu.
For the overburden and excavated materials stockpile area, stormwater runoff will be
❑ Yes ® No
treated in wet detention ponds. These ponds will also be designed to meet 90 percent
TSS removal and would discharge at non-erosive velocities.
n final aainuse flow plan is not incluaaea witn inis application Gecause a Curter variance is
required. Once final buffer variance determination has been made, UM will demonstrate
diffuse flow into the buffer when submitting its stormwater management plan to
Chatham County.
