V26-02 VALLEY PROTEINS ROSE FALL VVIF - DUPLIN COUNTY, NC
STORJMWATER, EROSION & SEDIMENT CONTROL PLAN
0 A. INTRODUCTION
The Valley Proteins facility in Duplin County is located at 469 Yellow Cut Rd at the
intersection of U.S. Highway 117, in Rose Hill, North Carolina, which is located in
Duplin County. Valley Proteins is proposing to construct a vehicle maintenance facility
building, wash building, associated parking areas, and drives at its existing facility. The
area of development is currently vacant, and is located within the existing facility
property boundaries. The site is shown on a vicinity map and is highlighted on the USGS
topographic map and included in this report. These improvements involve the disturbance
of approximately 6.50 acres of the site.
B. EXISTING CONDITIONS
The area of proposed development is currently grassed and wooded in fair condition.
The project site outfalls to an existing drainage ditch along the CSX Railroad rights-of-
iway, which eventually outfalls to Taylors Creek.
In the area of improvements, elevations range from 96 in the northwest corner of the site
to 91 feet at the southeastern corner. The site is located on the Rose Hill, North Carolina
USGS quadrangle sheet. A portion of this USGS quad map showing the site and general
drainage pattern is included in this Report.
C. SOILS CONDITIONS
The predominant soil types present on the site are GoA—Goldsboro loamy sand, RaA—
Rains fine sandy loam, and ToA—Torhunta mucky fine sandy loam. These soils are
generally characterized as moderately sloping, moderately well -drained to poorly drained
soils. A portion of the NRCS and Duplin County soils map and a general description of
the soil on the site are included in this Report.
D. PRE -DEVELOPMENT RUNOFF
For the purposes of this project analysis, the pre -development runoff was determined for
the project site (6.50-acres). The pre -development conditions are based on the existing

� J
V26-02 VALLEY PROTEINS ROSE HILL V,MF -- DUPLIN COUNTY, NC
STOR:MWATER, EROSION & SEDIMENT CONTROL PLAN
land use of the project site area, and overall drainage area, and curve numbers were
calculated based on this. The pre -development drainage divides are shown on drawing
DD-I in Appendix III.
Stormwater calculations for the pre -developed runoff were prepared using the Soil
Conservation Service (SCS) Technical Release 55 (TR-55) Methodology using
Drain:Edge Software. The two, ten, and one -hundred year, 24-hour storms were modeled
to establish pre -development peak flows per NCDENR and Duplin County requirements.
Data introduced into the model include area, hydraulic length, overland slope, and curve
number. Peak flows and volumes were generated by Drain:Edge for the pre -development
conditions going offsite. The output from Drain:Edge is included in Appendix III and is
summarized in Table 1 below.

100 Year

E. POST -DEVELOPMENT RUNOFF
The post development conditions result in an increase in impervious on the project site,
from pre -developed conditions, due to paving and building construction. A dry detention
basin will be utilized to facilitate stormwater quantity and quality for the site runoff.
The post -development drainage divides for the site are shown on drawing DD-2 in
Appendix IV. Curve numbers for the watersheds were selected based on the land use and
the soil type present. Stormwater calculations for the site were once again prepared using
the Soil Conservation Service (SCS) Technical Release 55 (TR-55) methodology using
Drain:Edge Software. The design storm for the drainage system is the ten year, 24- hour
storm event for Duplin County.

STORMWATER, EROSION & SEDIMENT CONTROL PLAN
Once again, the two, ten, and one -hundred year 24-hour storms were modeled to compare
the pre and post -developed peak flows from the detention basin for the project site.
Calculations generated by Drain:Edge for the post -development conditions can be found
in Appendix IV.
Tables 2 illustrates the post -development peak flows for each of the storm events for the
project site. For the project site, there is a reduction in peak flows for the 2, 10, and 100-
year storm events. The water surface elevation for the 100-year storm event passes
through the emergency spillway for the detention basin. Therefore, in our professional
opinion we feel that developed conditions for the project site will not cause any adverse
impact on downstream properties.

F. SEDIMENT CONTROL
In order to minimize erosion and migration of sediment during construction, sediment
control measures shall be provided for the site through the use of Best Management
Practices (BMP's). Some of the BMP's to be used on the site include grassing, silt fence
around the perimeter of the site, inlet protection around catch basins, gravel construction
entrance, diversions, stone check dams, and rip rap plunge pools at the discharge points
from the piped system. Additionally, the detention basin shall function as a sediment trap
until the site is stabilized. The erosion and sediment control plan is included in the
construction drawings along with a sequence of construction.

0 G. SPILLS AND NON-STORIVIWATER CONTINGENCIES
All fueling of equipment and vehicles will be conducted near the construction entrance
and staging area near the construction entrance. Any spillage will be removed
immediately. Contaminated soils will be placed on heavy plastic and covered or placed in
approved containers to prevent contact with storm water. Fueling will be done with a fuel
truck so there will be no onsite fuel tank or containment area. Oils, other vehicle fluids,
paints and solvents will be stored in the construction trailer or sealed storage trailers. Any
spill in excess of two gallons will be reported to the Owners representative.
If a release containing a hazardous substance in an amount equal to or in excess of a
reporting quantity established under either 40 CFR 117 or 40 CFR 302 occurs
during a 24 hour period, the contractor will immediately notify the permittee who
shall then do the following: notify the National Response Center (NRC) at (800) 424-
8802 and the North Carolina Department of Environment and Natural Resources
-_� Division of Water Quality 24 hour reporting number at: [phone]. Carlisle
Associates will then prepare a revision to this document to identify measures to prevent
the reoccurrence of such a release.
•
Each contractor is required to provide litter control for trash generated by their crew. A
dumpster for garbage will be located on the site and will be limited to garbage and paper
trash only. Paint cans, oil cans, used oil, and filters will be contained and disposed of by
the contractor by taking them an approved Hazardous Waste Disposal Center.
