5TORMWATER NARRATIVE
The proposed Benton Ready -Mix of Brunswick, Inc. facility will be located within the planning Jurisdiction of
Brunswick County on tax parcel number 18200092. The site 15 Just northeast of the Town of 5hallotte,
approximately 1 /3 miles north of U5 17. The address is 197 Barnhill Road, NW. The tract area 15 5.55 acres,
approximately 0.3G acres of which are wetlands. No wetlands are proposed to be disturbed during the
construction of this project.
Approximately 39.9% of the site will be covered by "built -upon area" (BUA). The large portion of the BUA will be
recycled asphalt or base material for the movement and parking of concrete mixer trucks. A smaller portion of the
BUA will consist of an office/maintenance budding, control house, well tank house, plant hopper/loadmg/conveyor
system, a mixer fueling area, a helicopter pad, and miscellaneous concrete surfaces associated with the mixer
washdown and concrete reclaim area. 5tormwater runoff from all of the BUA will be collected and directed to a
wet detention pond for treatment with the exception of a small portion of the entrance drive and the helicopter
pad (30 if 30'). The helicopter pad will be surrounded by grass surfaces graded to provide overland flow.
5tormwater collection will be by yard inlets, catch basin, storm drainage piping, and vegetated swales.
The 5tormwater pond 15 designed to treat the runoff from the first 1 I/2" of rainfall and to remove 30%, of
suspended solids in accordance with State regulations. The orifice in the pond outlet structure 15 sized to draw
down the "treatment volume" in approximately 2 i/2 days. In addition, the pond 15 designed to be in compliance with
the Brunswick County 5tormwater ordinance.
In addition to the State 5tormwater permit, application shall also be made for an AIPDE5 Discharge Permit for
Ready -Ma Concrete 51te5. Process wastewater will result from washdown of the surface of the mixer trucks
before they leave the site to deliver concrete and from the dumping of excess concrete from mixer trucks when
they return from deliveries. A reclalm/settling facility will be used to treat the process wastewater. A large
portion of the water used In this operation will be recycled; however, there will be some overflow into a vegetated
Swale that is part of the 5tormwater collection system that directs runoff to the wet detention pond. The
overflow is at the end of the settling basin where a large percent of the solids have been settled out. The settling
facility will be routinely cleaned out by front-end loaders which access the compartments of the settling basin by
ramps.

EROSION CONTROL PLAN NARRATIVE
Protect Description
Mr. Keith A. Benton, 5r., owner, plans to build this concrete batch plant under the name of Benton Ready -Mix of Brunswick, Inc. The site 15 just
northeast of the Town of Shallotte, approximately 1/3 miles north of US 17. The address 15 197 Barnhill Road, NW. The project site consists of 8.55
acres of which 0.3G acres are wetlands. No wetlands are proposed to be disturbed during the construction of this project.
Approximately 39.5% of the site will be covered by "built -upon area" (BUA). The large portion of the BUA will be gravel for the movement and parking of
concrete mixer trucks. A smaller portion of the BUA will consist of an office/maintenance building, control house, well tank house, plant
hopper/loading/conveyor system, a mixer fueling area, a helicopter pad, and miscellaneous concrete surfaces associated with the mixer washdown and
concrete reclaim area. 5tormwater runoff from all of the BUA will be collected and directed to a wet detention pond for treatment with the exception
of a portion of the entrance drive and the helicopter pad (30' x 30'). The helicopter pad will be surrounded by grass surfaces graded to provide
overland flow. 5tormwater collection will be by yard inlets, catch basin, storm drainage piping, and vegetated swales.
Site Description
The project area is currently wooded except for a mobile home site (unoccupied) in the northeast corner of the site and access road to the mobile home
site. The mobile home will be removed from the site prior to the completion of construction.
The project drams to a tributary of Williams Branch. Williams Branch 15 classified as C; 5w; HOW. Relief ranges from a maximum elevation of
approximately 53' at the northeast corner of the site and to a minimum elevation of approximately 42' at the southeast corner of the site. The primary
sod types based on the Brunswick County Sod 5ur✓eyare Baymeade and Goldsboro.
Adjacent Propertv
Woodlands surround the project to the north, east, and west. The tract to the south of the project is cleared and is currently being developed by
Southport Concrete Company.
Planned Erosion and Sedimentation Control Practices
The 5tormwater wet detention pond will serve as the primary erosion control feature during and construction of this project. This pond Will serve as a
sediment basin. Following construction and the 5tab1hzat1on of all disturbed surfaces, the pond will be cleaned of collected sediment.
Other erosion control features will include sediment fencing, a gravel construction entrance/exit, inlet protection at yard inlets and catch basm, and
temporary check dams within grassed -lined vegetative swales. Protective lining of swales during construction shall be jute net, fiberglass roving, or
double fiberglass roving as specified in the "Swale Data Table." All disturbed areas shall be stabilized by vegetative ground cover within 2 1 days
following any completion of grading unless the final gravel surface can be placed by that time. Within 2 1 days following completion of construction,
permanent ground cover over all disturbed areas not covered by BUA shall be established.
CONSTRUCTION SEQUENCE
1. The Contractor shall notify the NCDENR Land Quality Section, Wilmington Regional Office at (910) 79G-721 5 at least 48
hours prior to begmnmg construction.
2. Install construction entrance.
3. Clear alignments for all sediment fencing and install sediment fence.
4. Clear and grub the area for the 5tormwater detention pond. Construct the 5tormwater pond with outlet structure and
storm drain. Apply seed and mulch to disturbed areas and stabilize all slopes.
5. Clear and grub alignments/locations for swales, storm drains, and inlet5/junction box.
G. Construct swales, Inlets/junction box, and storm drains. Seed, fertilize, and mulch swales, apply protective liner, and install
check dams. Install inlet protection at yard inlets and catch basin.
7. Clear and grub areas for the drives, parkmcj, and structures.
8. Grade areas for the drives, parking, and structures.
9. Place gravel and construct structures.
10 Apply seed and mulch to all disturbed areas that are not covered with BUA.
r ir•T� ��,

EROSION CONTROL MAINTENANCE PLAN
I . Check all erosion and sediment control practices for stability and operation following every runoff -producmg rainfall event but in no case less than
once every week. Any needed repairs shall be made immediately to maintain all practices as designed.
2. The 5tormwater detention pond shall be cleaned out before the sediment reaches a level 3 feet below the orifice elevation. Immediately after
completion of construction and after all denuded areas have been stabilized with a vigorous vegetative cover, remove accumulated sediment from the
wet detention pond and restore the basin to the design elevations.
3. Check the 5tormwater pond orifice at least once a week and clear it of any obstructions. Replace orifice nipples that become damaged.
4.5ediment shall be removed from behind sediment fences before it reaches a level one-half foot deep at the fence. Fences shall be repaired as
necessary to maintain a barner.
5. All seeded areas shall be fertilized, reseeded, and mulched as necessary to maintain a vigorous, dense vegetative cover'.
G. Leave temporary check dams in -place until all areas upstream are stabilized.

STORMWATER FACILITIES MAINTENANCE
1. After every significant runoff producing event and at least monthly:
• Inspect the wet detention basin system for sediment accumulation, erosion, trash
accumulations, vegetated cover, and general condition.
" Check and clear the orifice of any obstructions such that drawdown of the temporary pool
occurs within 2 to 5 days. Replace orifice nipples that become damaged.
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. Remove trash as needed.
3. Inspect and repair the collection system (i.e. curb inlets, storm drains, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet detention basin main pond and forebay
immediately after completion of construction and after all denuded areas have been stabillzed
with a vigorous vegetative cover. Thereafter, remove accumulated sediment in each part of
the pond semi-annually or when water depth is reduced to values presented in the Stormrvater
Permit. 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. do not stockpile near the
wet detention basin, a stream, or any other water body).
5. Remove cattails and other indigenous wetland plants from the wet detention ponds wher they
cover 50%" of the basin surface. These plants shall be encouraged to grow along the
vegetated shelf and forebay berm.
6. Use a pump and/or siphon to draw down the basin in an emergency ores needed for
maintenance. If a pump is used its discharge should be directed into a sump to settle out
sediment prior to overflowing into a natural drainage feature.
7. Perform other maintenance activities as may be required to keep the wet detention pond and
collection system in good working order.
