Dear Mr. Hunsucker-
Dee Freeman
Secretary
ti
The Stormwater Permitting Unit received a complete Stormwater Management Permit
Application for Leon Levine College of Health Sciences Building on September 1, 2009; with
additional information on September 16, 2009 and September 24, 2009. Staff review of the
plans and specifications has determined that the project, as proposed, will comply with the
Stormwater Regulations set forth in Title 15A NCAC 2H.1000 and Session Law 2006-246. We
are forwarding Permit No. SW3090901, dated September 24, 2009, for the construction,
operation and maintenance of the subject project and the stormwater BMPs.
This permit includes BUA for future dorm buildings within the drainage area to the wet detention
pond. A site plan revision showing the buildings must be submitted and approved by DWQ prior
to the construction of these future buildings.
This permit shall be effective from the date of issuance until September 24, 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 permit. Failure to establish an adequate system
for Inspection and maintenance of the stormwater management system will result in future
compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory heading upon written request within thirty (30) days following
receipt of this permit. This request must be in the form of a written petition, conforming to

4. Sheet C-8 shows a 12" orifice, but the supplement states the orifice is 10". Please make
consistent.
5. Sheet C-8 shows the top of the riser at 551.85', but the supplement states the temporary pe'll
elevation is 552.8'. Please make consistent.
6. Please provide orifice drawdown calculations based on the minimum treatment volume
required. The average head to use in the orifice equation is approximately 1/3 of the distanec
between the PPE and the elevation of the next available outlet above the PPE.

High Density Commercial Wet Pond Project
Union County
Dear Mr. Hunsucker:
The Stormwater Permitting Unit received a complete Stormwater Management Permit
Application requesting a modification of the permit for Leon Levine College of Health Sciences
But ding on April 1, 2011. Staff review of the plans and specifications has determined that the
project, as proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC
2H.1000 and Session Law 2006-246. We are forwarding Permit No. SW3090901, dated April 4,
2011, for the construction, operation and maintenance of the subject project and the stormwater
BMPs.
This permit includes BUA for future dorm buildings within the drainage area to the wet detention
pond. A site plan revision showing the buildings must be submitted and approved by DWQ prior
to the construction of these future buildings.
This permit shall be effective from the date of issuance until September 24, 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 permit. Failure to establish an adequate system
for inspection and maintenance of the stormwater management system will result in future
compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following
receipt of this permit. This request must be in the form of a written petition, conforming 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
permit shall be final and binding.

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
The site will be. graded to flow_ into a piped storm drainage system into the forebay of the wet pond.. 'There is
also an pipe extension for future development across N. iylain Street. The volume for that future area has
been included in the calculations. The flow will flow throu_gh� t the riurao baffle to remove TSS and plantings
along the lateral shelf to remove floating oils of the panting lot. The water, is detained for 2 days to allow for
settlement and released in the outlet structure into a new pipe system under Pearl Circle.
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUT) Approval Date:

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BNEP. This maintenance record will be kept in a
log in a known set location. Any deficient SNIP 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 MAP.
The wet detention basin system is definer{ as the wet detention basin,
pretreatment including for( -.,bays 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 vet 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 dace safety expert should h-tspect the embaaknnent.
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.
