Project No: CA-03232
Carteret. County
Dear Mr. Brown:
On June 24, 2003, personnel of this office inspected a project located on Highvray 70 in Carteret
County, North Carolina. This inspection was performed to determine compliance with the North Carolina
Sedimentation Pollution Control Act of 1973. The inspection revealed a land -disturbing activity of
approximately 1 ,45 acres being conducted.
It is our understanding that you and/or your firm are responsible for this land -disturbing activity. The
purpose of this letter is to inform you that this activity was found to be in violation of the Act, NCGS 1 13A-50
to 66, and Title 1 5A, North Carolina Administrative Code, Chapter 4. If you feel that you are not responsible
for the following violations, please notify this office immediately.
The violations that were found are:
Failure to conduct a land -disturbing activity in accordance with the provisions of an
approved erosion and sedimentation control plan. G.S. 113A-61.1.
As stated in the approved plan, the stormwater pond and collection system was to be utilized as a
sediment basin during the construction phases of the project. At the time of the inspection, the
stormwater pond and collection system had not been constructed and land disturbing activities had
taken place.
The erosion and sedimentation control plan approved by this office on April 30, 2003 must be immediately
implemented on the site sufficient to restrain off -site sedimentation, or if that plan can no longer address the
field conditions, submit to this office a revised plan that addresses current erosion and sediment control
needs.
2. Failure on a tract of more than one acre, when more than one acre is uncovered, to install
sedimentation and erosion control devices sufficient to retain the sediment generated by the land -
disturbing activity within the boundaries of the tract during construction upon and development of the
tract. G.S. 1 13A-57(3).
Off site sedimentation had occurred in the southwest section of the tract resulting in sediment reaching
an adjacent waterbody. Off site sedimentation had also occurred along the north property line .

3. Failure to maintain satisfactorily all temporary and permanent erosion and sedimentation control
measures and facilities during the development of a site. 15 NCAC 413.0013.
Silt fence along the east side of the tract had exceeded 50% of its capacity. Silt fence in the
southwest portion of the tract had not been properly maintained.
To correct these violations, you must:
Construct stormwater pond as detailed in the approved plan or submit a revised plan.
2. Establish erosion control measures to prevent off site sedimentation in the southwest section
of the tract. Due to the actual elevation of the building pad, additional erosion control measures
are needed along the northern section of the tract.
3. Silt fence that has exceeded 50% capacity needs to be cleaned out. Additional silt fence that
has been damaged should be restored. , r.
If the violations described in this Notice are not corrected within 20 days following your receipt of this
Notice, the Division of Land Resources may take additional appropriate legal action against you pursuant to
NCGS 113A-64. That action could be the assessment of additional civil penalties and may result in the
initiation of other remedies as prescribed by the Act. If additional civil penalties are assessed for the violations,
the amount may be up to $5,000.00 per day for each day of the violation pursuant to NCGS 133A-64fa1(1).
If all violations are corrected within the time period specified for compliance, additional civil penalties or legal
remedies will not be pursued.
Any new land -disturbing activity associated with this project should not begin until the area presently
disturbed is brought into compliance with the Act. When corrective actions are complete, you should notify
this office so that the work can be inspected. You should not assume that the site is in compliance with the
Act until we have so notified you. In addition, once compliance has been achieved, all installed measures must
be satisfactorily maintained until development is complete and the site is fully stabilized to avoid further
violations of the Act.
We solicit your cooperation, and would like to avoid taking further enforcement action. At the same
time, it is your responsibility to understand and comply with the requirements of the Act. Copies of the
relevant statute and administrative rules may be examined at this office or will be sent to you upon request.
Should you have questions concerning this Notice or the requirements of the Act, please contact either Trentt
James or me at your earliest convenience.

A. Description of Project
I . Type of Development
This project consists of construction of a 8928 sf building with associated parking designated for 60
vehicles, driveway, drainage and site utilities. The site area is 1,45 acres.
2. Earth Disturbing Activities
a. Excavation and fill for building foundation and floor slab.
b. Grading associated with driveway and parking lot construction.
c. Excavation and backfill for site utilities.'
d. Excavation and backfill for installation of site drainage and excavation of the proposed stormwater
pond.
Soil types
According to the Carteret County Soil Survey, the soils are classified as Onslow loamy sand and
Lynchburg fine sandy loam.
4. Drainage
The site presently drains by surface runoff from the rear of the property southward to Highway 70
and then westward to the existing canal eventually draining to Hull Swamp (Class SQ. Following
construction, all stormwater will be directed in catch basins and drop inlets and then piped to a stormwater
detention pond adjacent to the Highway 70 right of way. Discharge from the pond will be piped to the
existing drainage canal located to the west of the property.
B. Erosion and Sedimentation Control Measures
The following measures are proposed for the site. If it becomes evident that additional erosion and
sedimentation control measures are needed, they shall be installed immediately. It is intended that all grading and
excavation activities within a certain area will be protected as soon as that activity is complete.
i . Sediment Fence - Sediment fence will be utilized as necessary in locations as shown on plans or as deemed
necessary by the engineer to insure that off -site sedimentation in controlled.
2. Sediment Basins- The detention pond to be site
between the parking lot an the highway will serve as
a sediment basin during construction. Sediment volume from the earth disturbing activities is estimated to be
3600 cubic feet based on 2.0 acres of disturbance. The pond has a capacity in excess of 9700 cubic feet.
Once construction is completed basin shall be cleaned to the original design depth,
3. Riprap outlet protection- Riprap to be installed at locations shown on plans to reduce energy at high velocity
areas.
4. Seeding - All disturbed areas will be seeded within 14 days following construction in accordance with the
seeding schedule shown on plans.

4. Seeding - All disturbed areas will be seeded within 14 days following construction in accordance with the
seeding schedule shown on plans.
5. Stone Construction Entrance - Stone construction entrance(s) will be used to reduce transport of sediment off
site.
6. Drop Inlet Protection - Inlet protection will be used to reduce the amount of sediment entering the storm
drainage piping system during construction. .
C. Time Sequence of Operations
l . Remove and/or relocate any existing obstructions.
2. Install stone construction entrance.
3. Install silt fencing at specified locations.
4. Clear and grub entire tract area for construction.
5. Excavate, rough grade and seed stormwater de3tention basin
6. Rough grade drive and parking area and begin preparation of building site.
7. Seed and mulch all areas of disturbance not to be paved within 14 days of land disturbance,
8. Install drop inlets and storm drainage piping within parking and drive area with sedimentation control
measures as shown on detail.
9. Install utilities.
10. Fine grade drive and parking area and place stone base course.
H. Construct building.
12. Pave drive and parking area.
13. Perform final grading, seed and mulch all remaining disturbed areas.
14. Remove accumulated sediment from stormwater detention basin and perform final grading of basin.
is. Install wet detention basin vegetation as specified on seeding schedule.
D. Design Assumptions
1. Design storm is ten years.
2. The rational method was used for design.
E. Wet Detention Basin Operation and Maintenance
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, grass cover, and general condition.
b. Check and clear the orifice and overflow device of any obstructions.
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 (piping, flumes, swales, rip rap) quarterly to maintain proper
functioning.
4. Remove accumulated sediment from the wet detention basin systems semi-annually or when depth is reduced
to 75% of the original design depth.
Main Basin Forebav
Pond original design depth; 4.00' 3.00'
sediment removal benchmark depth: 3.00' 2.25'
Removed sediment shall be disposed of in an appropriate manner in no way adversely impacting water
quality.
5. Remove cattails and other indigenous plants when they cover 50% of the basin surface.
F. Coastal Stormwater Regulations
The North Carolina Division of Environmental Management implemented coastal Stormwater regulations in
coastal counties on January 1, 1988, these regulations are detailed in 15 NCAC 2H.1000 Stormwater Runoff Disposal.
These rules allow for a development to be considered under various options. This project is submitted for approval
consideration under Section .1003(d)(2).
