Subject: Stormwater Permit No. SW8 000848 Modification
Brunswick Community College Applied Plant Sciences Facility
High Density Project
Brunswick County
Dear Dr. Greiner:
The Wilmington Regional Office received a Stormwater Management Permit Application for
Brunswick Community College Applied Plant Sciences Facility on December 1, 2006. 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. SW8
910501 Modification dated, December 21, 2006, for the construction of the subject project.
This permit shall be effective from the date of issuance until December 21, 2016, 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. Please also note the requirement for engineer's certification of the pond upon completion of
construction.
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 sixty (60) 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.
If you have any questions, or need additional information concerning this matter, please contact
Mary Jean Naugle, or me at [phone].
Sincerely)

NARRATIVE
DESCRIPTION:
The pr^sc, site is a large acre tract located on the campus of Brunswick
Community College. The soils of the site consist of lightly vegetated, sandy clay topsoil
and grades ranging from 0.5% to 2.0%. Approximately 3 acres will be graded to allow
construction of a new school building and retention area with paved access. The runoff
from the site is estimated using the rational method 10-year design storm and rainfall
data for the area. Construction is scheduled to begin as soon as all permits and
approvals are obtained.
EROSION CONTROL MEASURES:
The attached plans and specifications outline the requirements for erosion
control measures. Silt fencing will be provided where stormwater would be expected to
sheet flow from disturbed areas directly to adjacent property. Gravel check dams will
not be provided unless the Contractor has to temporarily discharge into an open ditch
instead of the proposed storm drain outfall. The detention pond will be used as a silt
basin during construction and restored to its design contours prior to completion. A
gravel construction entrance will be constructed at the project entrance. Maintenance
will be provided by the grading contractor and developer.
STORMWATER MANAGEMENT MEASURES:
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 Regulations. The
stormwater runoff from the development will be directed to the relocated stormwater
detention pond. This was originally permitted under SW8 000848 dated February 14.
2001.
CONSTRUCTION SEQUENCE:
The Contractor will install the gravel construction entrance and silt fence prior to
beginning any clearing and grading operations. Additional silt fence will be installed
when and if conditions warrant during construction. The detention pond/silt basin will
be constructed immediately after that portion of the site is cleared, and outlet structure
with protection will be installed. Disturbed areas will be landscaped or seeded upon
completion.

EROSION CONTROL NOTES AND MAINTENANCE PLAN
1. Install erosion control measures before beginning construction or as soon
thereafter as possible. All erosion and sediment control practices will be
checked for stability and operation following every runoff-producing rainfall but in
no case less than once every week. Any needed repairs will be made
immediately to maintain all practices as designed.
2. Maintain the gravel construction entrances in a condition to prevent mud or
sediment from leaving the construction site. The contractor shall inspect the
construction entrances on a daily basis. This will require periodic top dressing
with additional No. 4 stone. Any objectionable materials spilled, washed, or
tracked onto public roadways shall be removed immediately.
3. Install erosion control measures around the drop inlets as shown on the plans to
trap.silt during construction. Inspect the erosion control around the inlets after
each rain and make repairs immediately. Remove sediment when it becomes
0.50 deep to provide adequate storage volume for subsequent rains. When the
contributing drainage area has been adequately stabilized, remove all materials
and any unstable soil and either salvage or dispose of it properly. Bring the
disturbed area to proper grade and appropriately stabilize all bare areas around
the drop inlets.
4. Sediment will be removed from behind the silt fence when it becomes 0.5 feet
deep at the fence. The sediment fence will be repaired as necessary to maintain
a barrier. Silt fence stakes shall be spaced 6 feet apart unless a wire backing is
used with 8 foot stake spacing.
5. Inspect temporary sediment traps / check dams after each period of significant
rainfall. Remove sediment and restore the trap to its original dimensions when
the sediment has accumulated to one-half the design depth of the trap. Place
the sediment that is removed in the designated disposal area and replace the
contaminated part of the gravel facing. Check the structure for damage from
erosion or piping. Periodically check the depth of the spillway to ensure it is a
minimum of 1.5 ft below the low point of the embankment. Immediately fill any
settlement of the embankment to slightly above design grade. Any riprap
displaced from the spillway must be replaced immediately. After all sediment-
producing areas have been permanently stabilized, remove the structure and all
unstable sediment. Smooth the area to blend with the adjoining areas and
stabilize properly.
6. The stormwater ponds will act as sediment basins and will be cleaned out when
the level of sediment reaches 2.0 ft below the top of the riser. Gravel will be
cleaned or replaced when the sediment pool no longer drains properly.

'M NORRIS KUSKE TUNSTAL
7. The angle for graded slopes and fills shall be no greater than the angle that can
be retained by vegetative cover or other adequate erosion-control devices or
structures. In any event, slopes left exposed will, within 21 calendar days of
completion of any phase of grading, be planted or otherwise provided with
temporary or permanent ground cover, devices, or structures sufficient to restrain
erosion.
8. All disturbed areas shall be seeded within 15 days of disturbance. All seeded
areas will be fertilized, reseeded as necessary and mulched according to
specifications in the vegetative plan to maintain a vigorous, dense vegetative
cover.
9. More stringent measures shall be used to halt erosion if those shown on this plan
are not effective.
10. All erosion shall be controlled including side slopes before the project is
completed.
11. Remove , temporary measures upon completion of project. All permanent
measures will be well established before project closeout.

NARRATIVE
DESCRIPTION:
The project site is a 7.7 acre tract located on the campus of Brunswick
Community College. The soils of the site consist of lightly vegetated, sandy clay topsoil
and grades ranging from 0.5% to 2.0%. Approximately 3 acres will be graded to allow
construction of a new school building and retention area with paved access. The runoff
from the site is estimated using the rational method 10-year design storm and rainfall
