Dear Mr. Barnhill:
In accordance with your application for a discharge permit received on February 17,
2014, we are forwarding herewith the subject certificate of coverage to discharge under the
subject state - NPDES general permit. This permit is issued pursuant to the requirements of
North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North
Carolina and the US Environmental Protection Agency dated October 15, 2007 (or as
subsequently amended).
This certificate of coverage is not transferable. if the facility changes ownership or is
closed, the Division of Energy Mineral & Land Resources may require modification, revocation
or reissuance of the certificate of coverage.
Please be aware that mine dewatering at your site has the potential to impact adjacent
wetlands. The specific requirements for mine dewatering at facilities near wetlands can be
found in Part III, Section E of your permit. You must have an approved Operation anti
Monitoring Plan before mine dewatering discharges occur at lour facility. Discharging
mine dewatering wastewater without Plan approval will be subject to enforcement action. An
Operation and Monitoring Plan for your facility must be submitted to the Wilmington Regional
Office within 60 days of your receipt of this permit. Contact Dan Sams at the Wilmington
Regional Office at [phone] for more information about the approval process.
This site will discharge to a receiving stream designated as High Quality Waters
(HQW). As a result, a more stringent TSS limit and wastewater discharge volume applies.

Please note that mine dewatering wastewater includes wet pit overflows caused
solely by direct rainfall and groundwater seeps for this type of mining operation. Any
discharge of this water (and any stormwater commingled with it) is subject to the effluent
limitations in this permit.
This general permit allows the discharge of stormwater and certain types of
wastewater from your facility. In your application, you specified that only mine dewatering
water would be discharged from this facility. If separate point -source discharges of
stormwater occur (i.e., stormwater not combined with mine dewatering water), you will be
required to adhere to the conditions in this permit for stormwater discharges.
This project is Iocated in one of North Carolina's 20 coastal counties. Coastal
stormwater management rules (15A NCAC 2H .1000) may require an additional State
Stormwater Permit (different from the NPDES mining activities discharge permit). Please
contact Georgette Scott in the Wilmington Regional Office at [phone] to determine
if you will be required to submit an application for a State Stormwater permit.
This permit does not affect the legal obligation to obtain other permits which may be
required by the Division of Energy, Mining, and Land Resources, or any other federal, state, or
local authorities.
If you have any questions concerning this permit, please contact Larry Wade PE at
telephone number [phone].
Sincerely,
for Tracy E. Davis, P.E.

RE: Howard Pit
Onslow County
Operations and Monitoring Plan
Dear Mr. Bennett:
A
We are submitting an Operations and Monitoring Plan for the Howard Pit in Onslow County,
North Carolina based on our conversation February 11, 2014, to ensure that any dewatering activities that
may occur in correlation with mining activities shall not have any adverse effects on any nearby
jurisdictional wetlands 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 western edge of the mine nearest the property line. Any topsoil
in this area will be stripped and incorporated into the stockpile area as shown. The topsoil within
this area will be used to build any slopes after mining this area. The topsoil stockpile will be
seeded as needed to stabilize. We will strip areas as 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. As water is pumped into the basin, it will dewater through a riser and onto a
rip rap outlet pad as shown on the plan. This discharge will then dissipate through the 50'
undisturbed buffer to the on -site wetland.
4) After all mining activities in Phase I are complete, remaining topsoil stockpiled will be used to
build the finished 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 Phase I1 area in the same manner. Topsoil will be stripped as
needed and stockpiled as mining progress. As mining activities extend below the water table in
this area, water will be pumped into the existing dewatering basin. We will also use the newly
created pond for storage of pumped water from the new mining area. Pumping will be shared
between the on -site pond and dewatering basin as needed to ensure that discharge is kept to a
minimum, if any at all.
6) After all mining activities in the 15.0 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 wetland. 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 wetland 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.
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

STORMWATER POLLUTION PREVENTION PLAN
A. INTRODUCTION
This Stormwater Pollution Prevention Plan (SPPP) is for the Howard pit, located on
Bell Frazier Avenue off Highway 24, Onlsow County, North Carolina, Permit No.
NCG020537. The owner is Mr. Ricky Taylor of Bogue Sound Septic and Grading.
Mr. Taylor received a Notice of Violation (NOV- 2013-PC-0157) in July 2013.
This SPPP is provided to satisfy Item I of that NOV. Per approval by the Division
of Energy, Mineral & Land Resources, Department of Environment and Natural
Resources, the SPPP will be kept at the site or at the offices of the Permittee for
review by DENR personnel.
B. SITE PLAN AND PHYSICAL FACILITY DESCRIPTION AND LOCATION
As seen on the attached Site and Existing Condition Plan, (SP-1) the Howard Pit
(Pit) is located off the north side of Highway 24, with access from Bell Frazier
Avenue (N 34 43'30", W 77 12'08"). The Howard Pit is located on an 18.1 acre
parcel of land and includes two active mining areas and an existing pond.
The parcel includes multiple buffered areas. There is a 30 foot buffer which is
unexcavated around the existing pond and all stormwater run off is overland flow
across site, towards the existing pond and mining areas. The existing pond has
approximately 10 (minimum) feet of freeboard. No stormwater leaves the site.
However, one of the active mining areas has two permitted outfall discharge
locations. Outfall location 1 (see SDM -1) discharges to a rock check dam to ensure
velocities are non erosive, in keeping with NPDES permitted discharge point.
Outfall location 2 (See SDM-1) discharges via 8" outfall pipe and valve to Meadows
Pond, per agreement.
C. WATERSHED
As seen on the USGS Topo Map, Appendix 1, the receiving waterbody is Pasture
Branch, Queen Creek, within the White Oak River Basin. This is a SA;HQW
stream classification, Index Number 19-14-16.
As seen on attached Stormwater Drainage Map,(SDM-1) all stormwater run off is
overland flow across site, towards the existing pond and active mining areas. The
existing pond has approximately 10 feet of freeboard. One active mining area has
two outfall discharge locations. Outfall location 1 (see SDM -1) discharges to a rock
check dam to ensure velocities are non erosive, in keeping with NPDES permitted
discharge point. Outfall location 2 (See SDM-1) discharges via 8" outfall pipe and
valve to Meadows Pond, per agreement.

D. STORAGE
This is an active mining site. Mining of sand for fill is performed with typical
excavating equipment. Mined materials are staged into stockpiles. As seen in the
Site and ExistinIz Condition Plan (SP-1), the stock piles are adjacent to the mines,
but outside the buffers. From the stockpiles, the mined sand is loaded directly into
haul trucks. There are no permanent facilities located within the parcel. There is
minimal onsite storage of equipment at the site. As such, there is minimal to no
storage on site, other than the stockpiled mined materials. All equipment is
maintained at off site locations.
E. POTENTIAL POLLUTION SOURCES
The main source of potential pollution is erosion and dust. The access road is nearly
1900 feet long. It is a well compacted surface. The combination of compaction and
distance preclude creation of significant dust from haul trucks. In addition, the in -
situ soils of the site are sandy in nature and typically create minimal dusting
conditions. As discussed below, the site activities are very mature in nature. The
processes are repeated and there is little to no grading or excavating outside the
typical mining activities. The existing activity pattern is set and little to no new
erosion is created. However, as discussed below there is some silt fence in place to
ensure any eroded material created is precluded from the leaving the site.
F. RECENT SPILLS AND LEAKS
No spills or leaks, other than those of a very minor nature from equipment, have
occurred over the last three years. As such, no corrective actions have been
required or performed.
G. STORMWATER OUTFALL CERTIFICATION
There are no permanent or temporary utilities with the parcel. With this report, the
permitee has certified that the outfall has been evaluated by a professional engineer
and there is no evidence of non stormwater discharges from the existing pond or
the active mining areas.
H. SITE PLAN
See Section B above.
Page 4 of 6

I. EROSION AND SEDIMENT CONTROL PLAN
As seen on the attached Erosion and Sediment Control Plan, (ES-1) access to the pit
is along Bell Frazier Avenue from Highway 24. The primary source of erosion
would be along the mined area perimeters and along the access road. As discussed
in Section E above, the access road is well packed and is very stable in its existing
condition. This, in addition to the minimal amount of vehicle traffic, primarily haul
trucks, and the length of the access road combine to limit erosion of the site.
For additional protection, silt fence was placed along the perimeter in areas where
there was a possibility of erosion from mining activities to adjacent parcel.
J. STORMWATER MANAGEMENT PLAN
As noted above, the site drains overland into the existing pond and mining areas.
There are currently no discrete or structural controls, such as inlets or culverts, for
runoff into the pond. As discussed in Section C above and seen by the existing spot
elevations on the Stormwater Drainage Map (SDM-1), all stormwater runoff drains
overland flows within the site and the existing pond.
Within the existing pond, there is currently approximate 10 feet of remaining
freeboard. This is a significant volume for rainfall events. Within the active mining
area there is currently approximate 20 feet of remaining freeboard. This is also a
significant volume for rainfall events. Within the existing active mining areas, any
discharges are from the two outfall discharge locations. Outfall locations 1 and 2
(See SDM-1). For this report, an inspection of the outfalls was made by a
professional engineer (There are no discrete BMPs to inspect). There is no evidence
of any nature of erosive outfall velocities, pollutant spills or sediment at the
downstream locations, see attached photos.
A copy of the record of this inspection is attached. This inspection record is on
permanent file with engineer of record, KSMJ Engineering, pile, 388 McCotter
Blvd, Havelock, NC 28532, 252-444-5786.
Regarding the requirement for rainfall monitoring, a rainfall gauge is in place on
site. The gauge is checked by the permittee following rainfall events greater than
0.5 inches.
K. RESPONSIBLE PARTY AND EMPLOYEE TRAINING
The responsible party for the overall coordination, development and
implementation of this plan is the permittee, Mr. Ricky Taylor.
However, questions of a technical nature can be addressed through the engineer of
record, Susan Sayger, PE of KSMJ Engineering, pile.

NCG 020000 Permit SWPPP Requirements,
January 24, 2014
Da n,
I have reviewed the SWPPP submitted for the Howard Pit, Permit Number NCG020537, Mining
Permit Number 67-58 and have the following comments:
The SWPPP is missing:
1. Stormwater Management Plan
a. Management of Stormwater Runoff for the discharge into the wetland when the pump
is directed to the wetland on the south side of the northern pit. An NOV was issued
because the pump malfunctioned and a lot of sediment was discharged to the wetland.
A plan should be in place to prevent that from happening again.
b. BMP Controls Inspections and Maintenance.
i. Once every seven calendar days and within 24 hours after any storm event that
results in a discharge.
c. Secondary Containment Requirements and Records
2. Spill Prevention and Response Plan
3. Preventative Maintenance and Good Housekeeping Program
4. Employee Training.
I based this on the SWPPP requirements listed in the permit. Please let me know if you need
any additional information and what you would like me to do with the SWPPP submittal. I
would recommend that I contact the consultant that submitted the SWPPP and discuss the
omissions. Please let me know.
