Dee Freeman
Secretary
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for
South Point Business Park on October 15, 2009. Staff review of the plans and specifications has
determined that the project, as proposed, will comply with the Stonnwater Regulations set forth in Title
15A NCAC 21-1.1000 and Session Law 2006-246. We are forwarding Permit No. SW SW4091001, dated
November 20, 2009, for the construction, operation and maintenance of the subject project and the
stormwater BMPs.
This permit shall be effective from the date of issuance until November 19, 2019, and shall be subject to
the conditions and limitations as specified therein. Please pay special attention to the Operation and
Maintenance requirements in this pennit. Failure to establish an adequate system for inspection and
maintenance of the stonnwater management system will result in future compliance problems.
If any parts, requirements, or limitations contained in this pennit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within thirty (30) days following receipt of this
pennit. This request must be in the form of a written petition, confonning to Chapter 150B of the North
Carolina General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer 27447,
Raleigh, NC 27611-7447. Unless such demands are made this pennit shall be final and binding.
This project will be kept on file at the Winston-Salem Regional Office. if you have any questions, or need
additional infonnation concerning this matter, please contact Mike Randall at [phone]; or

RE: Stormwater Project No. S W4091001
Dear Mike:
Your comments dated November 5, 2009 have been reviewed and addressed as follows:
1. Comment: Provide sealed, signed and dated calculations.
Response: The attached calculations are signed and sealed.
2. Comment: High -density projects must use structural.storm1Val er nlcrtrage ment
systems that ll w,-'control and treat runofffrom the first one -inch of rain. I have
attached the calci.elations for the water quality treatment volume. Based on %BUA
and draina e area, the water quality treatment volume for the one inch design storm
is 49,828 ft . The supplement�%rm indicates the treatment volume to be 149,449 f 3.
The calculations were not Provided with the application crud tivhere the 149.449 ft3
came from can not be verified.
Response: The total volume provided is 149,449 W, which includes the temporary
and permanent volume. The temporary volume required is 49,549 ft3, see attached
calculations.
3. Comment: Runoff volume drawclown time must be a minimum of 48 hours, but not
more than 120 hours. The discharge rate for the water quality treatment volume
would need to be between 0.113 and 0.289 cfs. The 2.8 inch orifice would release
water quality treatment volume at 13.3 cfs.
UfS'% -1 A
Response: A drawdown time of 3 days was used to size the orifice
orifice would release at a discharge rate of 0.2 cfs. See attached,ca

4. ' Comment: SAIDA ratio provided in the supplement form indicates 0.44. For the
given BUA, 85% TSS removal and 3 foot minimum depth the ratio is 1. 61.
'Response: The entry of 0.44 on the previous supplement form referred to the surface
area required for the pond (0.437 acres). The supplement form has been corrected to
show the SA/DA ratio of 1.25, which reflects an average depth of 5 feet and 38
percent impervious cover.
5. Comment: Information on the seasonal high water table (SHWT) was not provided.
If the SHWT is below the permanent pool elevation (PPE), then a liner will need to be
provided in order to maintain the permanent pool. If a clay liner is proposed, then a
minimum 4-inch layer of topsoil shall be provided on the vegetated shelf for planting.
Response: There is a note included on Sheet C203 which instructs the contractor to
compact earthen material in the water quality.basin such that the infiltration rate is no
more than 0.01 in/hr. If the required infiltration rate cannot be met by compaction, a
Geosynthetic Clay Liner shall be installed. Compaction and infiltration rate to be
tested and verified by a geotechnical engineer.
6. Comment: High -density projects must discharge the water quality treatment volume
at a rate equal to or less than the predevelopment discharge rate for the one-year, 24-
hour storm. The pre -development peak flow rate was not provided on the supplement
form nor were the calculations provided. Normally with a properly sized orifice that .
meets the drawdown requirements will also be less than the predevelopment
discharge rate for- the one-year, 24-hour storm. But we will need to verify that it -
does.
Response: Refer to orifice calculation attached.
7. Comment: The supplement form indicates that the driving head Ha is 4 feet. The
supplement form also indicates that the temporary pool elevation is 817 fmsl and the
permanent pool elevation is 814 frnsl. The driving head is calculated using 113 the
distance between the elevation of the temporary and permanent pool, or 1.0 feet.
Response: The driving head used for the orifice calculation is 1.0. See attached
calculation.
8. Comment: Drawing C201 shows the runoff from ND-157 and ND-156 bypassing the
forebay.
Response: The topography of the site restricts the discharge locations of the
stormwater runoff to the main pond.
9. Comment: Provide a detail of level spreader.
Response: The level spreader detail has been included on Sheet C203.

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
® does ❑ does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— . No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
-- Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
