RE: NPDES NCG020000 NOI Application — Revised
River Road Pit, Tar River Mining Inc., Pitt County
Dear Mr. Lowther:
Please find enclosed a revised NPDES NCG020000 NOI Application for the River Road Pit located north
of Greenville in Pitt County, There are no point discharges leaving the mine site or operations. The
mining permit states that water will be contained within the mine. The first letter had stated a single
stormwater discharge was leaving the property form the farm pond, but this was in error. The farm pond
will remain as a farm pond and will not capture any sediment -runoff from the mine. The pond's outlet
and spillway were improved for better hydraulics, maintenance, and to serve as a future waterfowl
impoundment. There are discharges to a blue -line stream from swales that will be constructed along the
haul road. Stone filter check dams will filter stormwater runoff before discharging into the blue line
stream 50' buffer. The haul road crosses the blue -line stream where the existing farm road is currently
located. The mine will be dewatered, if necessary, and used for irrigation (approx. 250 gal/min pump) on
the crop fields. The mine will not be dewatered when irrigation is not needed. The dewatering or
irrigation will not discharge directly into adjacent wetlands and streams. The mining permit is currently
in review with the Division of Land Quality.
Sorry for the confusion and please let me know if you need additional information.
Sincerely,
J. Branch Smith, PE

Dear 11-'Ir. Vendemia:
Dee Freeman
Secretary
The Division of Water Quality's Stormwater Permitting Unit received a National Pollutant Discharge
Elimination System (NPDES) permit application for the River Road Mine on September 21, 2009. The
application indicated an associated application for a mining permit was submitted to the Division of Land
Resources (DLR). Please be aware that the issuance of an NPDES pemiit is contingent upon the issuance of
an associated mining permit from DLR. Our office will process your stormwater permit application once a
DLR mining permit has been issued for your project.
A copy of the mining plans :with all wetlands clearly delineated was not included with the application. I
talked with Branch Smith of GS3 and he said he would provide the plans as well as the Sediment and
Erosion Control Calculations.
Please also be aware that if your project is located near wetlands, your NPDES permit will require
dewatering operations without wetland impacts. The specific requirements for mine dewatering at facilities
near wetlands can be found in the text of the general NPDES mining permit number NCG 020000 available
on our website, http://h2o.enr.state.uc.us/su/Forms_ Documents.litm. See Section C, Part I of the permit on
the page labeled, "fart III Page 5 of 9". An approved Operation and Monitoring Plan is required for
NPDES-permitted mining facilities. Discharging mine dewatering wastewater without Plan approval will be
subject to enforcement -action. A Plan for your facility must be submitted to the Washington Regional Office
within 60 days of your receipt of an NPDES permit. We encourage you to contact Thom Edgerton at the
Washington Regional Office at [phone] to address any wetland concerns for your facility in order to
ensure a successful NPDES application review.
Per the requirements of the Tar -Pamlico Riparian Buffer Rule, all stormwater drainage to stream buffers,
from portions of this site that have been constructed after January 1, 2000, must be discharged through a
correctly designed level spreader or another device that meets diffuse flow requirements per 15A NCAC 213
.0259: Diffuse flow requirements are described in Chapter 8 of the North Carolina Stormwater BMP
Manual, available at: http://ii2o.enr.state.nc.us/su/bmp forms,htm

Thom,
Thanks for this email. I checked at this mine finally has its DLR Permit. 1 have attached the N01 and maps sent in for this
mine, River Road Mine in Greenville (Pitt County). The site discharges stormwater into the Tar River (WS-IV; NSW). The
only Stormwater should be swales along the haul roads.
Does the Washington Regional Office have any concerns about issuing this facility a COC for this general permit, and are
there any potential impacts to wetlands? If we don't receive any objections, we'll issue the COC in 30 days.

Subject: Re: River Rd Pit NPDES Gen Permit
Thom,
After several discussions and emails with Mr. Vendemia of Tar River Mining, we have decided to withdraw our application
for the NPDES permit to use the mine water for irrigation. Instead, we intend to proceed with our original plan to mine the
sand 'wet'. This is a common practice in sand mines, where the operator excavates down to a point just above the
existing water table, then steps the trackhoe down to this level to excavate as deep as the excavator can reach, For this
particular mine, Mr. Vendemia should be able to excavate down as far as 25 feet below existing ground.
No dewatering will be performed within the mine excavation area.
In the future, Mr. Vendemia can reclaim a pond section of the excavation area, have it inspected by the DENR, and get it
released from the mining permit and returned to agricultural use. At this point, the farm owner will be able to use the pond
for any agricultural purposes allowed, including irrigation.
Please let me know if you have any questions.

Subject: RE: River Rd Pit NPDES Gen Permit
Branch,
I got your message about the 0&M plan. The regional office approves the 0&M plan. You will need to contact Thom
Edgerton in the Washington Office about what they will require. The 0&M are required for mine dewatering activities
that have the potential to drain wetlands.
Here is an outline of what is required. 0&M Plan must include groundwater monitoring strategies to demonstrate the
effect of pumping and, as necessary, establish the pumping regime necessary to reduce impacts. The 0&M plan must
include detailed plans to maintain the surrounding hydrology and the respective monitoring to demonstrate
compliance. In order to complete the plan you will need to determine the amount of wastewater expected to be
discharged daily as a result of the dewatering and determine the cone of influence from the dewatering. The site must
be delineated and existing as well as seasonal wetland hydrology determined. The 0&M plan must have a wetland
monitoring plan that includes a Map of landscape positions, well information, physical monitoring for the wetlands
areas, settling ponds for sediment prior to dewatering, and explanation of how the dewatering will be conducted.
I don't have any examples but the regional office might have some. Let me know if you have any questions.

Were is the PCN submittal and DWQ's 1 st response. This was submitted in Aug. I think they have addressed most of
these issues by now, but I'm not sure. There is the JD Tear Sheets for the wetlands included in the attachments.zip file.
That's about all I have I think.

Yep, we hold the stormwater permit until the mining permit is issued.
Thanks for the information. Do you have any of the approvals you could forward me. I plan on talking with the
Washington Regional Office about it.

I understand the SW permit for the road swales. The mining permit is in process, so if I understood you right, the NPDES
permit will be issued after the mining permit is complete, correct?
*I was told the dewatering for irrigation has been applied forbefore I began working in the mine. It was a CCPUA
Notification to Div. Water Resources.

Subject: RE: River Rd Pit NPDES Gen Permit
Branch,
I sent a letter to the owner informing him we can issue a stormwater permit until they have a mining permit. The site
will need a stormwater permit based on the discharges to the swales from the haul road, As far as the dewatering be
irrigation, I believe you will need to have a permit from aquifer protection. Have you talked to them yet? I also have
concerns about all the surrounding wetlands being dewatered. Have these been delineated or is the data just from lidar
contours?

RE: NPDES NCG020000 NOI Application — Revised
River Road Pit, Tar River Mining Inc., Pitt County
Dear Mr. Lowther:
Please find enclosed a revised NPDES NCGO20000 NOI Application for the River Road Pit located north
of Greenville in Pitt County. There are no point discharges leaving the mine site or operations. The
mining permit states that water will be contained within the mine. The first letter had stated a single
stormwater discharge was leaving the property form the farm pond, but this was in error. The farm pond
will remain as a farm pond and will not capture any sediment -runoff from the mine. The pond's outlet
and spillway were improved for better hydraulics, maintenance, and to serve as a future waterfowl
impoundment. There are discharges to a blue -line stream from swales that will be constructed along the
haul road. Stone filter check darns will filter stormwater runoff before: discharging into the blue line
stream 50' buffer. The haul road crosses the blue -line stream where the existing farm road is currently
located. The mine will be dewatered, if necessary, and used for irrigation (approx. 250 gal/min pump) on
the crop fields_ The mine will not be dewatered when irrigation is not needed. The dewatering or
irrigation will not discharge directly into adjacent wetlands and streams. The mining permit is currently
in review with the Division of Land Quality.
Sorry for the confusion and please let me know if you need additional information.

RE: NPDES NCGO20000 NOI Application
River Road Pit, Tar River Mining Inc., Pitt County
To whom it may concern:
Please find enclosed NPDES NCG020000 NOI Application for the River Road Pit located north of
Greenville in Pitt County.
There is a single stormwater discharge leaving the property from a large farm pond that controls
stormwater runoff from the proposed mine excavation. The farm pond has been modified to a
wet retention pond with a flashboard riser -barrel outlet. This outlet will serve as a future
waterfowl impoundment after mining is completed. There are also discharges to a blue -line
stream from swales that will be constructed along the haul road. Stone filter check dams will
filter stormwater runoff before discharging into the blue line stream 50' buffer. The haul road
crosses the blue -line stream where the existing farm road is currently located. The mine will be
dewatered occasionally and used for irrigation (approx. 250 gal/min pump) on the crop fields.
The mine will not be dewatered when irrigation is not needed. The dewatering or irrigation will
not discharge directly into adjacent wetlands and streams. The mining permit is currently in
review with the Division of Land Quality.
Please let me know if any additional information is needed.

RIVER ROAD PIT
TAR RIVER MINING, INC.
STATE MINE PERMIT & NPDES GENERAL PERMIT COVERAGE
PITT COUNTY
FARM POND DESIGN CALCULATIONS
MINE LOCATION
The mine is located on 3351 Old River Road, which is north of Greenville in Pitt County, NC. The site
is bordered by the Tar River Creek to the south.
SOILS
According to the Web Soil Survey, the main soils are Lakeland sand and Chipley sand. Other soils
consist of Portsmouth, Tuckerman, Altavista, and Ocilla loams (occasionally wet soils). Lakeland has
hydrologic soil group type A and Chipley has hydrologic soil group type B. The main soils were used
to determine the SCS Runoff Curve Number.
FARM POND DESIGN NARRATIVE
The Tar River mine has an existing farm pond that will remain as is and no proposed mining will affect
the drainage to the pond. The pond will have a normal pool with a riser -barrel outlet device. This
detail can be found on the mine drawings. The pond was routed for the 10-yr, 25-yr, and 100-yr
design storms, which can be found in the attached routing spreadsheets. The 100-yr storm was
analyzed for dam overtopping, although the 100-yr storm on the dam will be outlet controlled due to
the Tar River floodplain. A rip -rap apron was sized per the Surface Mining Manual and is shown on
the mine drawings.
