2. Diffuse Flow
An additional condition is that all stormwater shall be directed as diffuse flow at non -erosive velocities through the
protected stream buffers and will not re -concentrate before discharging into the stream as identified within 15A NCAC
02B .0714(5) or provide treatment via an approved stormwater BMP meeting the nutrient removal requirements
established within 15A NCAC 02B .0714(a)(1)(2).

4. The Permittee shall replant the vegetation within temporarily disturbed areas associated with this project in an "in
kind" manner immediately following construction. (Example: Disturbed areas with pre-existing grassed lawns must
be replanted with grass. Disturbed areas with pre-existing trees or woody vegetation must be replanted with trees
and woody vegetation. Disturbed areas with pre-existing forest vegetation must be replanted with forest vegetation
including at least two different native hardwood tree species at a density sufficient to provide 260 trees per acre at
maturity. This density can usually be achieved by planting approximately 360 (11 x 11 spacing) to 538 (9 x 9 spacing)
trees per acre.) Restoration of trees/shrubs/forest must be completed by the first subsequent planting season
(November 1 through March 30). Note, if the tree plantings do not survive, they will need to be replaced such that
the density is sufficient to provide 320 trees per acre at maturity. [15A NCAC 02H .0507 (c), 15A NCAC 02H .0506
(b)(3), and 15A NCAC 02B .0714 (6)]

conditions. [15A NCAC 02B .0507(d)(2)]
6. This approval and its conditions are final and binding unless contested. {G.S.143-215.5)

GENERAL NOTES:
1. THE HF LEE OUTFALLS 005A AND 005B WILL HAVE THE TOP OF RIP RAP
WITHIN THE CENTER OF THE CHANNEL BE 1 FOOT BELOW THE CURRENT
ELEVATION. THE EDGES OF THE RIP RAP CHANNEL WILL RETURN TO
EXISTING ELEVATION GRADE (SEE PAGE HFL_C901.035.009 PER DETAIL 1).
THIS DESIGN ALLOWS THE WATER TO REMAIN WITHIN THE RIP RAP
APRON AND NOT SPREAD OUTSIDE OF THE RIP RAP APRON LIMITS PER
NPDES PERMIT REQUIREMENTS FOR TREATED WASTEWATER DISCHARGE
TO REMAIN AS A POINT SOURCE OUTFALL. THIS CURRENTLY PROPOSED
DESIGN WAS BASED ON A PREVIOUSLY COMPLETED AND APPROVED
DESIGN FOR THE CAPE FEAR PLANT IN 2019/2020.
