I When using the Division SAIDA tables, the correct SAIDA 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 85%TSS removal and 90%TSS removal.

STORMWATER MANAGEMENT
The project site is located in Brunswick County. Land disturbing on the site will
exceed one acre, which requires the site to comply with the State of North Carolina
Regulations. The stormwater runoff from the development will be directed to the
stormwater detention pond. The stormwater detention pond was designed to
accommodate this site at 62.05% impervious area lot coverage. The drainage area to
the pond will include some existing and some new impervious surfaces, as it is not
practical to separate the runoff.

Center Brunswick Community College Technical and Trades
Brunswick County
Dear Dr. Reaves:
The Wilmington Regional Office received a Stormwater Management Permit Application for
Brunswick Community College Technical and Trades Center on August 25, 2000. A preliminary review of
that information has determined that the application is not complete. The following information is needed
to continue the stormwater review:
I. The requirement to collect and treat all new impervious surface runoff has not been met and
adequate justification for not meeting this requirement has not been given. The narrative
and calculations are vague in describing why the new parking lot cannot be collected in the
pond. Please collect and treat runoff from all new impervious surfaces. In accordance,
correct the numbers on the application, supplement form and submit revised calculations.
The revised calculations should give the numbers for all existing impervious surfaces, all
new impervious surfaces, and how much of the existing surfaces drain to the pond.
2. Delineate the drainage area(0.948ac) to the pond.
3. Please verify,that there will be only one roof drain, as shown on planes, that drains the new
addition to the building. If there are more than one, please show how the others are being
directed to the pond.
4. The vegetative cover above the permanent pool is not specified on the plans, please do so.
5. On page 2 of 4 of the supplement form, please specify the type of mechanism proposed to
drain the pond for maintenance/emergencies for item I'm.".
6. Please give the approximate date as to when the existing building and parking were
constructed. In this situation the issue of phase development after 1988 has to be addressed.

l When using the Division SAIDA tables,the correct SAIDA 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 85%TSS removal and 90%TSS removal.
H. REQUIRED ITEMS CHECKLIST

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 2 to 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.
_3. Inspect and repair the collection system (i.e. catch 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�5dversely 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 4.12 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 3.0 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.

STORMWATER MANAGEMENT
The project site is located in Brunswick County. Land disturbing on the site will
exceed one acre which requires the site to comply with the State of North Carolina
Regulations. The stormwater runoff from the development will be directed to the
stormwater detention pond. The stormwater detention pond was designed to
accommodate this site at 80% impervious area lot coverage. A portion of the new
impervious area will not drain to the pond. However, a greater amount of existing
impervious surface will be directed to the pond to offset the deficiency.

NOTICE OF RECEIPT OF EROSION & SEDIMENTATION CONTROL PLAN
Brunswick Community College
Dr. Michael Reaves, President y
Post Office Box 30
Supply NC 28462
Dear Dr. Reaves:
This office has received a soil erosion and sedimentation control plan for the project listed below which was
submitted as required by the North Carolina Sedimentation Pollution Control Act (NCGS 113A-57(4)).
Please be advised that this Act requires that all persons disturbing an area of one or more acres of land
must obtain approval of a soil erosion control plan prior to the commencement of said land disturbing activity
(NCGS 113A-54(d)(4)). The act further states that this plan must be filed a minimum of 30 days prior to the activity
and the approving authority must approve or disapprove the submitted plan within 30 days of receipt. Failure of
the approving authority to approve or disapprove the submitted plan within the 30 day period will be deemed
approval of the plan. Commencement or continuation of a land-disturbing activity under the jurisdiction of this Act
prior to the approval of an erosion and sediment control plan is a violation of the Act.
A copy of any erosion and sediment control plan which could involve the utilization of ditches for the purpose
of dewatering or lowering the water table is forwarded by this office to the Division of Water Quality (DWQ). It is
suggested that you contact Joanne Steenhuis at [phone] of DWQ if the ditches shown on your plan will
lower the water table.
The approval of an erosion and sediment control plan is conditioned on the applicant's compliance with
Federal and State water quality laws, regulations and rules.
If you have questions, please do not hesitate to contact this office. Your cooperation in this matter is
appreciated and we look forward to working with you on this project.
Sincerely,
Carol N. Miller, CPESC
