The Washington Regional Office received a completed Stormwater Application for modification to
permit SW7040604 on April 20, 2005. 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. We
are forwarding Permit No. SW7040604 dated May 19, 2005 to Farr Developing, LLC for the construction and
operation of four wet detention ponds and grass lined swales to serve Currituck Industrial Park located at the
East end of Dr. Newbern Road in Currituck County, NC. This permit replaces permit SW7D4D5D4 issued
August 5, 2004. Enclosed is a copy of the approved modified portion of the plans.
This permit shall be effective from the date of issuance until May 19, 2015 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 operation 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

Re: Currituck Industrial Park
Stormwatcr Permit No. SW7040604
Dear Mr. Thorpe:
The purpose of this letter is to certify that, based on periodic inspections throughout the construction
process, the stormwater management appurtenances associated with the above referenced project have
been constructed in substantial conformance with the approved plans.
Plantings associated with the wet pond construction have been installed. Due to the drought conditions
that we are currently experiencing as well as pumping of groundwater from sand pits on two adjacent
sites flanking the subdivision, the water level within the ponds is currently low. This low water level has
adversely impacted the health of the planted vegetation. The required plants will be monitored as the
basins re -fill and normalize, and additional plantings will be made as needed as prescribed by the basin
maintenance requirements.
If you have any questions, or require any additional infonnation, please do not hesitate to contact me at
[phone]. Thank you for your assistance with this project.
Sincerely,
D

Subject: Stormwater Permit Renewal
Stormwater Management Permit SW7040604
Currituck Industrial Park
Currituck County
A Division of Energy, Mineral, and Land Resources file review has determined that .
Stormwater Permit SV 7040604 for a stormwater treatment system consisting of four
wet detention ponds serving the Currituck Industrial Park located at the East end of Dr.
Newbern Road in Currituck County expires on May 19, 2019. This is a reminder that
permit renewal applications are due 180 days prior to expiration. We do not have a
record of receiving a renewal application.
Please submit a completed permit renewal application along with a $505.00 fee for
permit renewal. Permit application forms for renewal can be found on our website at:
iittps:/Ideq.nc^ oovv/about/divisions/energy-mineral-land-resoui-ces/enemy-mineral-land-
rule,s'Istormwater-program/post-construction. North Carolina General Statutes and the
Coastal Stormwater rules require that this property be covered under a stormwater
permit. Failure to maintain a permit subjects the owner to assessment of civil penalties.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you. If you would like I can e-mail you a copy of the
renewal application. You can request a copy by e-mailing me at

Footnotes:
When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90%,TSS removal. The NCDENR BMP manual provides design tables for both 95% TSS removal and 90%'I'SS removal.

actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 In the 20 coastal counties, the requirement for a ve getative filter may be waived if the wet detention basin is designed to provide
90% TSS removal. The NCDENR BMP manual provides design tables for both 85% TSS removal and 90% TSS removal.
II. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stormwater Best Management Practices Manual
(N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code
Section: 15 A NCAC 2H .1008.
Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached. If the applicant has designated an agent in•the Stormwater Management Permit
Application Form, the agent may initial below. If a requirement has not been met, attach justification.
Applicants Initials
a. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).
OA L _ _ b. The forebay volume is approximately equal to 20% of the basin volume.
DA , c. The temporary pool controls runoff from the design storm event.
OA is d. The temporary pool draws down in 2 to 5 days.
e. If required, a'30-foot vegetative filter is provided at the outlet (include non erosive flow
calculations)
b ' D f. The basin length to width ratio is greater than 3:1.
P7 A f7 g. The basin side slopes above the permanent pool are no steeper than 3: 1.
D9 1) h. A submerged and vegetated perimeter shelf witha sfope of 6:1' or less (show detail)."'
t31 fi i. vegetative cover above the permanent pool elevation is specified.
DH 1) j. A trash rack or similar device is provided for both the overflow and orifice.
N / k. A recorded drainage easement is provided for each basin including access to nearest right-
of-way.
1. If the basin is used for sediment and erosion control during construction, clean out of the
;basin is specified prior to use as a wet detention basin.

III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
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) 0 does X does not incorporate a vegetated filter at the outlet.
This system (check one) 0 does 'Odoes not incorporate pretreatment other than a forebay.
Form SWU-102 Rev 3.99 Page 2 of 4

Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs
within Ito 5 days as designed.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
Inspect and repair the collection system (i.e.'caich basins; piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed
of in an appropriate manner and shall be handled in a manner that will not adversely impact water quality
(i.e. stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate"into accumulated sediments.
When the permanent pool depth reads 2. 25 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads ;�,;?5 feet in the forebay, the sediment shall be removed.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain shall be minimized to the maximum extent practical.

7. All components of the wet detention basin system shall be maintained in good working order.
