Dear Mr. Arnolt:
Dee Freeman
Secretary
The Division of Water Quality issued a Coastal Stormwater Management Permit, Number SW8 010120 to SouthSide
Business Park for a High Density project on October 22, 2001, This permit expires on October 22, 2011, Per 15A
NCAC 2H.1003(h) (the stormwater rules), applications for permit renewals shall be submitted 180 days prior to the
expiration of a permit and must be accompanied by a processing fee, which is currently set at $505.00. If this is still
an active project please complete and submit the enclosed renewal application prior to April 22, 2011. If this project
has not been constructed and a permit is no longer needed, please submit a request to have the permit rescinded. If
you have sold the project, or are no longer the permittee, please provide the name, mailing address and phone
number of the person or entity that is now responsible for this permit. Enclosed is a form for change of ownership,
which should be completed and submitted if the property has changed hands.
Your permit requires that upon completion of construction and prior to operation of the permitted stormwater
treatment system, a certification of completion be submitted to the Division from an appropriate designer for the type
of system installed. This is to certify that the permitted facility has been installed in accordance with the permit, the
approved plans, specifications and supporting documentation. Please include a copy of the certification with your
permit renewal request and processing fee. Enclosed is a copy of a sample certification. Also enclosed is a new
Operation and Maintenance agreement that should be completed and submitted along with your renewal application.
You should be aware that failure to provide the Designer's Certification and the operation of a stormwater treatment
facility without a valid permit, are violations of NC General Statute 143-215.1 and may result in appropriate
enforcement action including the assessment of civil penalties of up to $10,000 per day.

responsibility for meeting the built -upon area limit is transferred to the individual property owner.
3. if an Architectural Review Committee (ARC) is required to review plans for compliance with the BUA

requirements of the permit. Within the time frame specified in the notice, the permittee shall submit a written
time schedule to the Director for modifying the site to meet minimum requirements. The permittee shall
provide copies of revised plans and certification in writing to the Director that the changes have been made.
7. The stormwater management system shall be constructed in it's entirety, vegetated and operational for its
intended use prior to the construction of any built -upon surface.
During construction, erosion shall be kept to a minimum and any eroded areas of the system will be repaired
immediately.
9. Upon completion of construction, prior to issuance of a Certificate of Occupancy, and prior to operation of
this permitted facility, a certification must be received from an appropriate designer for the system installed

and specifications, and other supporting documentation. Any deviations from the approved plans and
specifications must be noted on the Certification.
10. Decorative spray fountains will not be allowed in the stormwater treatment system.
11. If the stormwater system was used as an Erosion Control device, it must be restored to design condition prior
to operation as a stormwater treatment device, and prior to occupancy of the facility.

1. Please delineate all wetlands on site, disturbed or undisturbed, or note on the plans that none exist.
1 Please provide the permanent pool and forebay dimensions; and make sure that they add up to 11,098
ft'. Based on scaling, I get only 10,800 ft2, which could be attributed to print stretch/shrink.
Please specify the wetland species to be planted on the 6:1 shelf.
4. Please initial page 4 of the application.
Please add the nearest major intersection to the vicinity map.
Please list the maximum BUA per lot, in square feet, on page 3 of the application.
