Re: Dairy Farm Pit
NPDES Permit Application
I am respectfully submitting an application for an NPDES discharge permit for a borrow pit in Pitt
County. An on-site determination of potential jurisdictional features was performed by the
Environmental and Soil Service, Inc. The location of the wetlands and the proposed buffers are also
shown on the enclosed site plan.
Barnhill Contracting Company proposes to pump water from a rim ditch into the dewatering
basin as shown on the mine map during the initial start of the excavation. This basin has been designed
for a 1,000 gallons per minute pump and a detention time of 2 days. Once this area is mined of its
material, it will then be used for storage of dewatering from the next phase of the mining area. Water
will be pumped into the basin and pond utilizing a 6" submersible pump (Thompson Pump Model
46HST) at an average rate of approximately 650 gallons per minute. This pit will be operated for Barnhill
Contracting projects only and will not be run on a continual basis. Use will be determined by demand
for sand for local projects. Because of the nature of this work, withdrawal rates and discharge will vary
greatly from month to month. We intend to dewater only when we are actively mining sand and not on
a continuous basis. During times of mining we will typically work 12 hour days and pump during those
times. Therefore, any discharges will be kept to a minimum. We have also applied for a CCPCUA
withdrawal permit through division of Water Resources since this site is within Edgecombe County.
Erosion control measures will be installed onsite prior to any land disturbance taking place.
Please reference the site plan for a more detailed depiction of these measures. Any water within the
mining area will be directed to drain towards the pit. There are also diversion ditches with check dams
along both sides of the haul road to control runoff from this area.

38) A WaSteWater treatment alternatives reviewis required by 15A NCAC 2H.0105 (c)(2)
for any new or expanding water pollution control facility discharges in North Carolina. You may
attach additional sheets. List the types of wastewater this mine site will discharge:
8 Mine Dewatering
❑ Process Wastewater (such as washing or recycle system overflows, other mining activity wastewater)
a) What wastewaters were considered for this alternatives review? 0 Dewatering ❑ Process WW
b) Connection to a Municipal or Regional Sewer Collection System:
i) Are there existing sewer lines within a one -mile radius? ..................................... ✓❑ Yes ❑ No
(1) If Yes, will the wastewater treatment plant (WWTP) accept the wastewater? .... ❑ Yes [Q✓ ] No
(a) If No, please attach a letter documenting that the WWTP will not accept the wastewater.
(b) If Yes, is it feasible to connect to the WWTP? Why or why not?* PLEASE SEE THE ATTACHED
LETTER FROM THE EDGECOMBE COUNTY UTILITY DIRECTOR IN REGARDS TO
NOT ACCEPTING THE WASTE WATER.
c) Closed-loop Recycle System (meets design requirements of 15A NCAC 2T.1000):
i) Are you already proposing a closed-loop recycle system (CLRS)? ......................... ❑ Yes 0 No
(1) If Yes, for what type of wastewater at this mine site? ❑ Dewatering ❑ Process WW
(2) If No, is this option technologically feasible (possible)? Why or why not?*
A CLRS IS NOT TECHNOLOGICALLY FEASIBLE BASED ON THIS SITE IS IN A RURAL COUNTY WITH
LIMITED RESOURCES.
(3) If No, is it otherwise feasible to build a CLRS at this site? Why or why not?*
A CLRS IS NOT FEASIBLE BECAUSE IT WOULD BE TO COSTLY FOR THE AMOUNT OF DISCHARGE
THAT WILL TAKE PLACE. SINCE THE AMOUNT OF WATER THAT WILL BE DISCHARGED WILL
SOLELY BE BASED ON THE AMOUNT OF DEVELOPMENT IN THE SURROUNDING AREA, OUR NEED
TO DISCHARGE WILL VARY GREATLY.
(4) What is the feasibility of building a CLRS compared to direct surface water discharge?*
AS STATED ABOVE, THE NEED TO DISCHARGE WILL VARY GREATLY FROM MONTH TO MONTH.
BARNHILL CONTRACTING COMPANY WILL ONLY BE PUMPING WHEN WE ARE ACTIVELY MINING.
d) Surface or Subsurface Disposal System (e.g., spray irrigation):
i) Is a surface or subsurface disposal technologically feasible (possible)? ..................... ❑ Yes 21 No
Why or Why not? * SINCE THE PIT IS LOCATED IN EDGECOMBE COUNTY, WHICH ISA RURAL
AGRICULTURAL BASED COUNTY, IT WOULD NOT BE TECHNOLOGICALLY FEASIBLE DUE TO THE COST
AND THE VARIANCE IN THE NEED TO DISCHARGE BASED OFF OF THE NEED.
ii) Is a surface or subsurface disposal system otherwise feasible to implement?*............ ❑ Yes [01 No
Why or Why not?* BECAUSE OF THE SURROUNDING LAND ACTIVELY BEING USED AS FARM LAND,
BARNHILL CONTRACTING COMPANY WOULD IMPACT MORE LAND IMPLEMENTING A SPRAY
IRRIGATION SYSTEM THEN PUMPING INTO A DEWATERING BASIN AND THE WATER SPILLING OUT
THROUGH A RIP RAP SPILLWAY INTO AN ONSITE DITCH.

NCG020000 N.O.I.
iii) What is the feasibility of employing a subsurface or surface discharge as compared to a direct
discharge to surface waters?* BECAUSE THE NEED TO DISCHARGE WILL VARY GREATLY, IT IS NOT
FEASIBLE TO EMPLOY A SUBSURFACE OR SURFACE DISCHARGE BECAUSE SOME MONTHS WE MAY
NOT DISCHARGE AT ALL. OUR DISCHARGE SOLELY DEPENDS ON THE FUTURE DEVELOPMENT
IN THE SURROUNDING AREA.
e) Direct Discharge to Surface Waters: Is discharge to surface waters the most environmentally sound
alternative of all reasonably cost-effective options for the wastewaters being considered?*
0 Yes ❑ No
f) If this review included all wastewater discharge types, would excluding some types (e.g. mine
dewatering) make any of the above non -discharge options feasible for some of the wastewaters?
❑ Yes El No

RE: Dairy Farm Pit
Edgecombe County
Operations and Monitoring Plan
Dear Mr. Edgerton:
We are submitting an Operations and Monitoring Plan for the Dairy Farm Pit in
Edgecombe County, North Carolina, to ensure that any dewatering activities that may occur in
correlation with mining activities shall not have any adverse effects on any nearby jurisdictional
streams that may be present on the property. Reference is made to the site plan that
accompanies this Operations and Monitoring Plan, which illustrates the mining activities as they
shall occur on the site.
The type of discharge that will be present on the site will be mine dewatering.
Reference is made to the site plan that illustrates the points of discharge from the mine.
Barnhill Contracting Company proposes to dewater mining operations through the following
sequence of events:
1) Erosion Control items will be installed prior to any mining activities on the site.
Sediment Basins and Diversion Ditches will be installed per plan design before mining
activities begin in the mining area.
2) Mining will begin in on the most north/northwestern edge (5.0 acre area) of the mine
nearest the property line. This area has already been approved under the express
permitting process, EDGEC-2018-008. Any topsoil in this area will be stripped and
incorporated into a small berm that would extend around the perimeter edges of the
pit. The topsoil within these berms would be used to build any slopes after mining this
area. The topsoil berms will be seeded as needed to stabilize. We will strip areas as

800 Tiffany Blvd., Suite 200
Rocky Mount, North Carolina 27804
252-823-1021 phone
www.barnhillcontracting.com
mining progresses to prevent unnecessary erosion from occurring. Diversion ditches
will be utilized to divert shed water towards the sediment basin.
3) As mining activities extend below the water table, water will be pumped as needed into
the borrow pit dewatering basin. In case excess water flows over the edge of the
existing basin, a rip rap outlet will be installed at the lowest point and any discharge will
dissipate through the 50' undisturbed buffer to the on-site man made ditch.
4) After all mining activities in this 5.00 acre area are complete, any remaining topsoil
stockpiled will be used to build the slopes of the pond to a grade of 3:1 or flatter above
the water table, and permanently seeded.
5) Mining will then begin in the remaining 21.10 acre area in the same manner. Topsoil
will be stripped as needed and used for berms around the perimeter of the pit. As
mining activities extend below the water table in this area, water will be pumped into
the existing 5 acre excavation area for storage of pumped water from the new mining
area. Pumping will be shared between the on-site dewatering basin and newly created
pond as needed to ensure that discharge is kept to a minimum, if any at all.
6) After all mining activities in the 26.10 acre area are complete, any remaining topsoil
stockpiled will be used to build the slopes of the pond to a grade of 3:1 or flatter above
the water table, and permanently seeded.
The proposed operation has been designed so that any overflow from dewatering
activities or extreme rainfall events will take a natural course to the closest ditch. Water will be
pumped at a rate not to exceed 936,000 gallons per day, as dictated by our CCPCUA withdrawal
permit, utilizing a Thompson 6" submersible pump (model 46HST or comparable). The
estimated volume of water withdrawal from dewatering activities will be recorded. Storm
water will be managed within the pit utilizing silt fence, diversion ditches, sediment basins,
buffers, and berms when topsoil is available. Reference is made to the site plan, which
illustrates the design specifications and size of the sediment basin.
There will be an undisturbed buffer established between the mine footprint edges and
the jurisdictional ditch edge. The 50' undisturbed buffer along the edge of the mine limits will
be adequately marked with orange safety fence to ensure that heavy equipment does not enter
into this area and land disturbing activities do not occur.

Rocky Mount, North Carolina 27804
252-823-1021 phone
www.barnhillcontracting.com
Barnhill Contracting Company will work to inspect and monitor the jurisdictional
features that appear within the property boundary daily, during times that pumping and
discharge are occurring. Barnhill Contracting Company will inspect and monitor the features to
reaffirm the presence of the jurisdictional feature and soils, as well as, for the instability,
erosion, sloughing, subsidence, collapse, newly formed sinkholes, wetland vegetation
degradation, and/or flooding of ditch from discharge activities. Barnhill Contracting Company
does not foresee any impacts to the adjacent features or wetlands, but will secure the
appropriate 401 Permit if the need arises.
Together with data collected by NCDENR- Division of Water Quality from their
inspections, Barnhill Contracting Company and NCDENR- Division of Water Quality can
determine if there are any detrimental impacts to the property's jurisdictional features. During
inspections conducted by Barnhill Contracting Company, if there are any detrimental impacts to
the property's wetlands discovered, Barnhill Contracting Company will immediately cease
dewatering activities, and report the discovery to NCDENR- Division of Water Quality
Washington Regional Office. Together, Barnhill Contracting Company and NCDENR- Division of
Water Quality will determine how these impacts can be abated.
Should you require any additional information, please do not hesitate to contact us.
Yours very truly,
Barnhill Contracting Company

Summary
The objective of this report is to provide Barnhill Contracting Company with the environmental evaluation for the
proposed Rhodes Pit as required by the North Carolina Department of Transportation (NCDOT). The environmental
evaluation was done in accordance with Borrow and Waste Site Reclamation Procedures for Contracted Projects as
presented by NCDOT'.
Barnhill Contracting Company proposes to excavate material/dirt from a site located in north -central Edgecombe County,
North Carolina (Figure 1). It is understood the dirt removed from the site will be used on the Kingsboro Industrial Site
located in Edgecombe County (NCDOT Project #0204145). There is one (1) borrow pit and a haul road being proposed
for the site (Figure 2). The borrow pit is planned to be located in an open farm field area and the haul road is planned to
connect the borrow pit to Hwy 97 by exiting the borrow pit area in the area of some existing farm buildings, then by
traveling through an existing farm field to Hwy 97.
1.0 Introduction
This report and analysis was done using NCDOT guidance outlined in Borrow and Waste Site Reclamation Procedures
for Contracted Projects'. In addition, information obtained from guidance document Skaggs Method for Determining
Lateral Effects of a Borrow Pit on Adjacent Wetlands2 was used in this report and evaluation.
1.1 Site Description
The site was located off Hwy 97 in Edgecombe County, North Carolina. The coordinates are latitude 35.969610 and
longitude -77.639869. The proposed pit is located in an existing agricultural field. The proposed pit area was bound on
the north and west by a narrow wooded area and another agricultural field. There was a wooded area and another
agricultural field to the east of the site. To the south of the site was an agricultural field and a farm operation with several
out buildings (Figure 2).
The soil in the area of the proposed pit was typical of Coastal Plain deposits found on stream terraces. The soils formed
from fluvial and marine sediment.
The Tar River was located +/-1.4 miles to the south. Key Branch and/or its small tributaries ran from areas on either side
of the site to the Tar River (Figure 1).
The topography of the area was relatively flat to gently rolling. There was a general drop in elevation from the proposed
borrow pit area to all surrounding areas; however, the drop in elevation was more prominent to the west. Several small
wetland areas were located adjacent to the area proposed for excavation (Figure 2, 3 & 4).
1.2 Project Description
Barnhill Contracting Company proposes to excavate material from a borrow pit that will be used to supply dirt for the
local Kingsboro Industrial Paris Project. The site was located at 132 Rhodes Dairy Lane, Rocky Mount, NC. The borrow
pit and haul road are proposed to be located on parcel number 480029065900, which consists of a total of +/- 121.2
acres. The proposed excavation area of the borrow pit is +/- 26 acres.
A typical excavation depth of 16 to 20 feet is planned for the site. Dewatering of the pit will be required while excavation
is taking place. Once the pit is closed out, water levels will be allowed to return to natural levels. No outlets or overflows
will be built into the pond once the pit is closed out
A haul road is proposed to enter the site off Hwy 97. The haul road will continue through an existing agricultural field,
then between existing farm buildings to the proposed pit area (Figure 2).

1.0 Methods
Field investigations were used to describe soil conditions, vegetation, and landscape position and to identify any features
such as local streams and wetlands. Hand auger soil borings were used to gather soil information and to determine soil
characteristics such as depth of horizons, texture, structure, color and consistence.
Relative ground elevations at the locations of soil borings and other ground levels were shot with a laser level. The
elevations are not actual elevations but are elevations used to determine site specific characteristics. An elevation of
60.00 feet was assigned to a nail (temporary bench mark) placed in a power pole on the southeast comer of the site
(Figure 4). All other elevations were determined relative to the temporary bench mark. Elevations of groundwater levels
were determined by measuring static groundwater in open bore holes and subtracting measurements from the relative
ground elevations.
The wetlands were delineated in accordance with the 1987 Wetland Delineation Manual and Adandc/Gulf Coast
Regional Supplement. The Clean Water Act was enacted to protect waters of the United States, which includes
wetlands. Section 404 of the Act gives authorization to the Secretary of the Army, acting through the Chief of
Engineers to issue permits for the discharge of dredge or fill material into waters of the United States. Before the
wetland delineation can be considered official, the delineation must be verified and determined to be jurisdictional or
non jurisdictional by a representative of the US Army Corps of Engineers (USACOE).
All soil borings, wetland flags and other pertinent items used to development our site maps were located with a GPS unit
capable of sub -meter accuracy.
Recommendations are given based on site specific work that included soils identification, wetland and stream
determinations, groundwater levels and other site specific characteristics.
2.0 Preliminary Wetland Delineation
Wetlands and open waters that were within or near 400 feet of the proposed borrow pit and near the proposed haul road
were identified and flagged. Before the wetland delineation can be considered official, the delineation must be
verified and determined to be jurisdictional or nor -jurisdictional by a representative of the US Army Corps of Engineers.
Based on criteria for adjacency or connectivity areas of wetlands or open waters were determined to be jurisdictional or
non jurisdictional from a preliminary standpoint (Figure 2, 3 and 4).
2.1 Borrow Pit
Jurisdictional 404 wetlands or waters of the US were identified to the northeast, east, south and southwest of proposed
the proposed pit (Figure 2, 3 and 4). These areas are identified as Wetland "A", Wetland "C", Wetland "D", Wetland "E"
and Jurisdictional Waters. Wetland "A", "C" and the Jurisdictional Waters were within 400 feet of the proposed borrow pit.
Wetland "A" was 302 feet from the proposed borrow pit at its closest point Wetland "C" was 232 feet from the proposed
borrow pit at its closest point The jurisdictional waters/pond was 79 feet from the proposed borrow pit at its closest point
Wetland "D" and "E" were outside the 400 foot perimeter around the borrow pit and were not in the vicinity of the
proposed haul road; therefore, these wetland areas should be of no consequence to this environmental evaluation.
The waters/pond located east of the proposed borrow pit had connectivity to traditionally navigable waters (Tar River) via
a ditch that flowed from the pond, across the field in a southerly direction and to a tributary of Key Branch, which flowed
to the Tar River. For this reason, the pond was determined by ESS to be jurisdictional.
There was an abandoned farm lagoon (upland impoundment) located south of the proposed borrow pit area. Near the
impoundment was an upland pond. The pond was dug to supply spoil for the formation of the lagoon. The pond had no
connectivity to any stream or wetland and was in an upland landscape position; therefore, the pond should be
considered non jurisdictional. The abandoned lagoon should also be non jurisdictional.

2.2 Haul Road
The proposed haul road is planned to enter the site off Hwy 97, cross and existing agricultural field and enter the pit area
between existing farm buildings (Figure 2). A potential wetland area was located near Hwy 97 in the vicinity of the
proposed haul road (Figure 2 and 3). The potential wetland area can be avoided by routing the haul road to the west of
the potential wetland area.
3.0 Identification of Surface Waters/Riparian Buffers
The site lies within the upper Tar River watershed (HUC 03020101). A review of North Carolina Division of Water
Resources (NCDWR) documents indicate the Tar River and its tributaries are currently subject to riparian buffers3.
Streams and potential streams in the vicinity of the site were identified. A review of USGS topographic maps (Figure 1
and 3) showed potential streams to the south, west and east of the site. The Edgecombe County Soil Survey showed
potential streams to the south of the site; however, the streams do not extend to the east and west of the site as shown
on USGS maps (Figure 5).
The streams shown on USGS maps appear to be potential tributaries of Key Branch. The tributary to the east of the site
was outside the 400 foot perimeter established around the proposed borrow pit, therefore, this tributary should be of no
consequence to this environmental evaluation. With the exception of a small portion to the northwest of the site, the
entirety of the potential tributary to the south and west of the site was outside the 400 foot perimeter. The portion that is
shown within the 400 foot perimeter is shown as "man-made ditch" on Figure 2, 3 and 4. This feature was 304 feet from
the proposed borrow pit at its closest point. An investigation of the potential stream revealed a man-made ditch that was
located at the edge of the existing agricultural field. It is the opinion of ESS, that this ditch would not be classified a
stream based on NCDWR standards and would not be subject to riparian buffers. A stream call would most likely be
needed by NCDWR if the feature is determined to be of consequence with respect to the excavation of the borrow pit
4.0 Determination of Seasonal High Water Table (SHWT) and Stratigraphy
A series of seven (7) soil borings were conducted at various landscape positions in the areas of the proposed pit. The
locations of these soil borings are shown on Figure 4.
4.1 Soil Drainage
The soils within the area of the proposed pit ranged from moderately well drained on the eastern portion of the proposed
pit to well drained on the western portion the proposed pit.
4.2 Detennination of Seasonal High Water Table (SHWT)
Soil characteristics and measured depths to static groundwater were used to determine the depth of the SHWT at each
soil boring. The depth to the SHWT ranged from 2.33 feet below the surface at B7 to 6.67 feet below the surface at B4
(Figure 4). Table 1 gives the relative elevations of the ground surface, SHWT and static groundwater levels (STWL) at
each boring location.

4.3 Soil Descriptions and Stratigraphy
Soil descriptions were recorded at each of the soil borings. Stratigraphy to a depth of 20 feet was based on information
gathered from soil borings conducted by ESS and exploratory excavations made by Barnhill Contracting Company. Soil
descriptions are available upon request. The soils were characterized by sandy loam textured material from the surface
to a depth of 8 to 20 inches ("A" Horizon). A horizon ("Bt" Horizon) of sandy clay loam soil was encountered from just
below the "A" horizon to a depth that ranged from 3 to 4 feet. A course loamy "BC" horizon was found from the bottom of
the "Bf' horizon to a depth of 4 to 5 feet. Course sand ("C" horizon) was found below the "BC" horizon. The soil was in
area of the proposed pit was most like the Wickham soil series. Soils in the field to the west of the site and wetland areas
were most like the Roanoke soil series.
Based on information obtained from Mr. Brent Caudle of Barnhill Contracting, the sand extended to a depth of at least 20
feet in the area of the proposed pit. For the purpose of this evaluation, the impermeable layer will be assumed to be at a
depth of 20 feet since no data was available for depths greater than 20 feet.
5.0 Excavation Below the SHWT
To determine the feasibility of excavating below the SHWT, the depth to the SHWT was determined as described in
subsection 4.2 of this report. In addition to determining the depth to the SHWT, the direction of groundwater flow and
groundwater gradient was determined based on information gathered on site. These items are needed to determine if
"Skaggs Method" calculations are needed in situations where the proposed excavation may impact wetlands or streams
within 400 feet of the proposed disturbance area and concurrence from the USACE is being requested in situations
where reduced buffers are being requested2. As our evaluation has determined, there are wetlands and jurisdictional
waters within 400 feet of the proposed pit.
5.1 Depth of Excavation
Barnhill Contracting Company has indicated the typical excavation depth to be 16 to 20 feet. The highest ground
elevation in the proposed borrow pit area was on the southwest comer of the site (Table 1). If excavated to a depth of 20
feet, the bottom of the pit would be at a relative elevation of 40 feet. This excavation depth would place the bottom of the
pit 13.34 feet below the SHWT at B4. Due to the excavation being below the SHWT and measured static groundwater
levels across the site, dewatering of the pit will be needed.
5.2 Direction of Groundwater Flow
The NCDOT document Skaggs Method for Determining Lateral Effects of a Borrow Pit on Adjacent Wet/ands2 describes
three (3) pit types in which the direction of groundwater is considered. The reason for determining the direction of
groundwater flow is to determine if excavations from the borrow pit, that will result in dewatering of the pit, will result in a
negative impact on the hydrology of any nearby wetland. The three (3) pit types described in the document are: 1. Flow
from wetland to pit 2. Flow from pit to wetland and 3. Flow through pits: wetland to pit on one side, pit to wetland on
other side 2.

To determine the direction of groundwater flow, groundwater levels were measured and relative elevations calculated.
The relative elevations were then used to determine the groundwater contour and direction of groundwater flow by
using the triangulation method (Figure 4). Before any excavation or dewatering takes place, the general direction of
groundwater flow was determined to be from the area east of the proposed pit 1, across the proposed pit area and
toward the wetland area (Wetland "C") located on the southwest side of the proposed pit (Figure 4). Given the relatively
low groundwater gradient, it is likely dewatering of the pit will effect surrounding hydrology for the period dewatering
takes place. After the pit is closed out and no outlets are created for water to escape the pit, the hydrology of the area
should return to levels encountered before excavation and dewatering.
6.0 "Skaous Method"
The "Skaggs Method" must be used for determining reduced buffers in situations when wetland hydrology may be
affected by dewatering, wet mining or excavations below the SHWT and when the borrow pit is a type 1 or type 3
as defined in the Skaggs Method for Determining Lateral Effects of a Borrow Pit on Adjacent Wetlands2. The current
status of hydrology in the area would be type 3. A type 1 pit would result temporarily as the pit is dewatered.
The analysis of hydrology indicates the "Skaggs Method" would be required in this case.
6.1 "Skaggs Method" Results
Inputs into the model were from site specific data and estimated data from the Soil Survey. The Step -by -Step
Guide for "Skanas Method" Program was used when determining inputs. The deepest water level allowed in the
model is 6 feet, which was used as the water level in the pit. Surface depressional storage in the wetland was set
at 1 inch. The depth to the impermeable layer was set at 10 feet in the wetland area. The depth to the
impermeable layer in the area pf the proposed pit was determined to be 20 feet. The Wetland "C" was 10 feet
below the ground elevation at 134. This would place the depth of the impermeable layer at 10 feet below the
surface in the area of the wetland. The wetland soil were best characterized by the Roanoke soil series. Since no
on site hydraulic conductivity measurements were taken, the model inputs for a Roanoke soil were used.
Drainable porosity was set at a conservative value of 0.035. The resulting lateral effect was calculated to be 133.6
feet (Appendix 1).
6.2 Effects on Wetland Hydrology
The jurisdictional wetlands/waters identified within 400 feet of the proposed borrow pit were Wetland "A", the
Jurisdictional Waters/Pond and Wetland "C". The results of the "Skaggs Method" indicate a lateral effect of 133.6
feet. Wetlands "A" and "C" are greater than 134 feet from the proposed borrow pit at their closest point (Figure 4).
Based on this information a reduced buffer should be allowed for wetlands "A" and "C".
Due to close proximity of the jurisdictional waters/pond located east of the proposed pit, the hydrology issue must
be addressed in more detail. One solution could be reduce the size of the pit to accommodate a minimum
setback of at least 134 feet from the pond to the pit. At present the pond is located +/-79 feet from the proposed
pit. Another solution may be to pump water into the pond as needed to maintain current water levels. Daily
monitoring of the water levels would be needed to assure water levels are maintained at current levels.
7.0 Federally Protected Species
ESS conducted an investigation of the disturbance areas (Borrow Pit and Haul Road) to determine if federally protected
species may exist. Appendix 2 is a list from the US Fish and Wildlife Service of these species in Martin County. None of
the species or habitat for the species listed were observed in the area of the proposed pit or haul road.
8.0 Flood Zone
A review of FEMA maps indicate the area of the proposed pit or haul road are not located within a flood zone (Figure 6)

9.0 Conclusions
Barnhill Contracting Company plans to excavate material from a proposed borrow pit located off Hwy 97 in Edgecombe
County, North Carolina. An environmental evaluation was conducted by ESS to identify wetlands, streams, protected
species and flood zones that may be impacted by the activities related to the proposed project.
The evaluation revealed wetlands within 400 feet of the proposed borrow pit and haul road. After reviewing the proposed
activities and applying pertinent rules and regulations, it appears the activity can be achieved without adverse effects to
the wetland hydrology of wetland "A", wetland "C or the potential wetland area located near Hwy 97.
The "Skaggs Method" calculations indicate a lateral effect of 134 feet, which would affect only the jurisdictional waters
located to the east of the site. Proper measures can be taken to insure hydrology of the pond remains as is during the
dewatering phase of the operation.
After completion of the excavation and dewatering of the pit, the water level in the pit will be allowed to return to pre-
operation levels.
Based on information provided by Barnhill Contracting Company, the site does lies adjacent to but not within any flood
zone based in FEMA maps. No federally endangered species were observed in the area of the proposed pit or haul
road.

Federally Protected Species

3gecomoe e:ounty tnaangerea bpectes, 1nreatenea species,reaerai ... attps://www.rws.gowrateign/species/cntyiisvedgecombe.htmi
North Carolina, the Asheville and Raleigh Field Offices of the US Fish and Wildlife Service (Service) define Federal
Species of Concern as those species that appear to be in decline or otherwise in need of conservation and are under
consideration for listing or for which there is insufficient information to support listing at this time. Subsumed under
the term "FSC" are all species petitioned by outside parties and other selected focal species identified in Service
strategic plans, State Wildlife Action Plans, or Natural Heritage Program Lists.
T(S/A) = threatened due to similarity of appearance. A taxon that is threatened due to similarity of appearance with
another listed species and is listed for its protection. Taxa listed as T(S/A) are not biologically endangered or
threatened and are not subject to Section 7 consultation. See below.
EXP = experimental population. A taxon listed as experimental (either essential or nonessential). Experimental,
nonessential populations of endangered species (e.g., red wolf) are treated as threatened species on public land, for
consultation purposes, and as species proposed for listing on private land.
P = proposed. Taxa proposed for official listing as endangered or threatened will be noted as "PE" or "PT",
respectively.
Bald and Golden Eagle Protection Act (BGPA)•
In the July 9, 2007 Federal Register( 72:37346-37372), the bald eagle was declared recovered, and removed (de-
listed) from the Federal List of Threatened and Endangered wildlife. This delisting took effect August 8,2007. After
delisting, the Bald and Golden Eagle Protection Act (Eagle Act) (16 U.S.C. 668-668d) becomes the primary law
protecting bald eagles. The Eagle Act prohibits take of bald and golden eagles and provides a statutory definition of
"take" that includes "disturb". The USFWS has developed National Bald Eagle Management Guidelines to provide
guidance to land managers, landowners, and others as to how to avoid disturbing bald eagles. For mor information,
visit http://ww-w.fws.g�v_/m igratorybirds/baldeagle.htm
Threatened due to similarity of appearance(T(S/AD:
In the November 4, 1997 Federal Register (55822-55825), the northern population of the bog turtle (from New York
south to Maryland) was listed as T (threatened), and the southern population (from Virginia south to Georgia) was
listed as T(S/A) (threatened due to similarity of appearance). The T(S/A) designation bans the collection and
interstate and international commercial trade of bog turtles from the southern population. The T(S/A) designation has
no effect on land management activities by private landowners in North Carolina, part of the southern population of
the species. In addition to its official status as T(S/A), the U.S. Fish and Wildlife Service considers the southern
population of the bog turtle as a Federal species of concern due to habitat loss.
Definitions of Record Status:
Current - the species has been observed in the county within the last 50 years.
Historic - the species was last observed in the county more than 50 years ago.
Obscure - the date and/or location of observation is uncertain.
Incidental/migrant - the species was observed outside of its normal range or habitat.
Probable/potential - the species is considered likely to occur in this county based on the proximity of known records
(in adjacent counties), the presence of potentially suitable habitat, or both.
