Dear Mr. Shepherd:
Dee FreLrnan
Secretary
On June 23, 2009, I, Michael Lawyer from the Fayetteville Regional Office of the Division of Water Quality,
conducted a site inspection at the Black Ankle Quarry facility located at 371 Black Ankle Road near Star, Montgomery
County, North Carolina. A copy of the Compliance Inspection Report is enclosed for your review. Ms. Stephanie Graham
and Mr. Doyle Carlisle were also present during the inspection and their time and assistance is greatly appreciated.
Stormwater from this facility drains to an unnamed tributary to the Little River, a Class C stream located in the
Yadkin/Pee-Dee River Basin. The site visit and file review revealed that the subject facility is covered by NPDES
Stormwater General Permit-NCG020695.
Please refer to the enclosed Compliance Inspection Report for additional comments and observations made
during the inspection.
Please be advised that violations of the NPDES General Permit are subject to a civil penalty assessment
of up to $25,000 per day for each violation. If you or your staff has any questions, comments, or needs assistance with
understanding any aspect of your permit, please do not hesitate to contact me at [phone].

Permit: NCG020695 Owner - Facility: Martin Marietta Materials, Inc.
Inspection Date: 06123/2009 Inspection Type: Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
Inspection conducted to ensure compliance with the conditions of the NCG020000 general permit for mining activities.
Met onsite with Ms. Stephanie Graham and Mr. Doyle Carlisle who explained that active mining operations ceased in July
2008 due to the economy, Owners want to maintain permit coverage should operations resume. A review was conducted
of the facility's Stormwater BMP Plan and monitoring records from 2008 as supplied by Ms. Graham. The BMP Plan
contains all permit -required items. The mine is set up such that all process water and pit dewatering enter an existing pit
that is without a discharge outlet, Water from the pit can be used as process water if needed. Quarterly Analytical
Monitoring records from 2008 into 2009 show that no discharges have occurred from this pit. Monitoring records for
stormwater was also available for review and all parameters were below Cut-off Concentrations, however there was no
actual discharge event and the samples were taken from inside one of the settling ponds. It was relayed that sampling
and subsequent analysis applies only to the discharge of stormwater from the mine property and that documentation of
'No Discharge' should be recorded as similarly done regarding process wastewater monitoring. Qualitative Monitoring
records for stormwater were not available, however as reported by facility personnel there have been no discharge events
since Martin Marietta acquired ownership of the mine in March of 2008.

Re: Wetlands Operations and Monitoring Plan
Black Ankle Quarry (Seagrove Quarry) — COC NC6020695
Montgomery County
Dear Ms. Henson:
This letter is to inform the Division of Water Quality that as of July 18, 2008, Black Ankle Quarry,
previously known as Seagrove Quarry, temporarily ceased all mining operation at the site. At this
time, we are not dewatering the pit, thus eliminating the requirement of monitoring the wetland area
designated by the previous owners. Currently, we are not monitoring the three wells installed to
comply with the Operation and Monitoring Plan. Before mining operations are initiated again, we will
notify DWQ and submit to you, our request to have the Operation and Monitoring Plan modified.
Also, on December 16, 2008, we submitted documentation to the Division of Water Quality, Surface
Water Protection Section in Raleigh to change the name and ownership of this quarry. At this time, we
have not received a response concerning this submittal, nor have we received an invoice for the annual
NPDES Permit Fee.
Thank you for your assistance in this matter, and should you have any questions or need any additional
information, please feel free to contact me at 336-215-5497 or e-mail me at

Dear Ms. Henson:
Please find enclosed a copy of the completed Permit Name/Ownership Change Form submitted to
DWQ at the address on the form to change the ownership of the Seagrove Quarry NPDES General
Permit over to Martin Marietta Materials, Inc. This quarry will now be known as Black Ankle Quarry.
Martin Marietta Materials, Inc. completed the purchase of this quarry on March 17, 2008.
Limited operations were conducted after we purchased the property, and as of July 18, 2008, the
quarry has been temporarily shut down. Per our phone conversation on December 11, 2008, the
requirements of the Wetlands Operations and Monitoring Plan have not been fully implemented since
we acquired the property. As we discussed, we will evaluate the monitoring wells during the month of
December, and submit this information to your office in January 2009. Please note that we have
submitted the required DMR's to Raleigh Central Office beginning the second quarter of 2008. We
have not had a discharge from this property since our acquisition.
During the recent review of our files, it was determined that the permit required wetland monitoring,
which is unique from any other permit we hold for this region. It is our intention to begin the required
monitoring of this area, and comply with the reporting requirements of the permit. We would like to
meet with you in early 2009 to ensure we have full understanding of the requirements of the Wetlands
Operations and Monitoring Plan approved for this site.
Thank you for your assistance in this matter, and we will contact you in early January to schedule a
meeting. Should you have any questions or need any additional information, please feel free to
contact me at 336-215-5497 or e-mail me at [e-mail].

Pursuant to our phone conversation, this is to enter into the record our
agreement regarding the frequency of future reports under the Wetlands Operating and
Monitoring Plan as required by the above referenced permit.
Our Operating and Monitoring Plan as submitted to DENR tailed for quarterly
sulimi#tals bf the data recovered during our monitoring; however, now that we are nine
months into the monitoring, we feel that frequency is unnecessary. Future reports will be
filed on a semi-annual basis in July and January. Each will cover the previous six
months monitoring results, i.e., January -June and July -December.
Should you need additional information or have any questions, please contact
the writer.

INTRODUCTION
As issued by the Division of Water Quality of the NC Dept. of Environment and
Natural Resources, General Permit No. NCG020000 - COC NCG020695, for the
Seagrove Quarry of Little River Stone, LLC, required the preparation and
implementation of an Operation and Monitoring Plan for the protection of adjoining
wetlands due to the potential of draining them as a result of pit dewatering (Section C-1).
This Operation and Monitoring Plan was submitted to the Division of Water Quality on
February 12, 2007 and approved by the DWQ on March 14, 2007. A copy of this plan is
attached under Appendix "A". The following is a report of monitoring activities
performed under that plan during the remainder of 2007.
RAINFALL DATA
Attached under Appendix "D" is a summary of rainfall at the site since April,
2007. As can be seen, the total rainfall over the nine -month period has been only 23.89
inches, which is well under normal and highlights the serious drought conditions that
have plagued the area for most of 2007.
GROMMATER HYDROLOGY MONITORING
Attached under Appendix "B" is a Wetlands Monitoring Plan drawing that shows
the locations of three monitoring wells, as well as pertinent information regarding them,
that were proposed in the Operation and Monitoring Plan. These wells were installed on
March 23, 2007.
Attached under Appendix "C" is a Wetlands Monitoring Summary which includes
a summary of the water level readings taken from these wells twice monthly beginning
on April 6, 2007. Note that the ground water level in MW-1 was fairly consistent up
until mid -June, at which point the level fluctuated for a month and then dropped
drastically, such that the well was dry for August - October. The water level has
recovered somewhat over the last two months as rainfall in October and December were
more normal. However an extremely dry November caused a fluctuation in that partial
recovery.
MW-2 showed just a couple of inches of water after it was installed and, since
then, has been dry except for a reading in late April. The water level in MW-3 dropped
fairly consistently after it was installed and has been dry since mid -July.

SURFACE WATER HYDROLOGY MONITORING
The Wetlands Monitoring Plan drawing in Appendix "B" also shows the locations
of three transect lines that have been established along the drain where flow monitoring
has been performed in accordance with the Operation and Monitoring Plan. The
Wetlands Monitoring Summary in Appendix "C" summarizes the results of the flow
monitoring that has been performed twice monthly since April.
As can be seen from this summary, Section A -A at the head of the drain
experienced an actual flow of water for only the first two weeks of the monitoring during
the month of April. The rest of the year this section of the drain was dry, even though the
associated monitoring well in this area (MW-1) did not show an appreciable drop in
water level until June.
Section B-B, just upstream from MW-2 maintained a steadily decreasing flow
from April through July, but then was dry until the end of December. At that time, there
was a slight pooling of water in the drain from a trickle that was not measurable.
Section C-C, near MW-3, showed a steadily decreasing flow until the end of June.
For the rest of the year, no flow was recorded at this location.
Overall, there was water pooling in certain short reaches of the drain at times in
December, but no noticeable flow. This was obviously trapped water remaining in these
reaches as a result of runoff from the surrounding area during the storm events of that
month.
VEGETATION MONITORING
In Appendix "E" can be found pictures of the three transect lines and monitoring
well locations as taken on 6/2/07 in accordance with the Operation and Monitoring Plan.
These photos show the vegetation at each point. No additional photos were taken in the
fall as called for in the plan due to an oversight. However, there appeared to be no
impact on the vegetation from the drought conditions except for the ferns that are
abundant in certain areas on the bank of the drain. These suffered as the drought
conditions deepened into the fall.
STATUS QF - __ G AND DEFATERING
The quarry pit is currently approximately 3 acres in size and a maximum of
approximately 40' deep. The corresponding floor elevation is approximately 580', which
is approximately 10' above the level of MW-1 (570'). Some water, likely a combination
of groundwater and stormwater runoff has collected in the pit; however, dewatering of
the pit has not yet been started. The surface elevation of this collected water is
approximately 590', or about 20' above the level of MW-I.

S Y AND CONCLUSIONS
The wetland area has definitely suffered a lack of water during most of 2007, as
evidenced by the monitoring data, but the cause would appear to be the severe drought
and not the mining operation. Mine dewatering has not yet commenced and water levels
in the pit would appear to indicate that there has been no disturbance of the water table in
the area from the mining.
The initial water level readings in the monitoring wells seem to indicate that the
ground water table in the drain area was not very high in the upper and lower reaches of
the drain and thus not conducive to a "high functioning" wetland system. The water level
readings in MW-2 in the mid -reach of the drain system seems to indicate that this stretch
was never a "true functioning" wetland system, but rather simply a perched wet area due
to the presence of impermeable clay soil and a more level topography that captured and
held runoff from the area above it.
FUTURE CONSIDERATIONS
The Operation and Monitoring Plan as approved by the Division of Water Quality
indicated that monitoring results would be submitted quarterly. Based on our monitoring
performed to date, we do not feel that this is necessary at this time. We propose to
monitor through June 2008 and submit a report by the end of July. We will take new
photos along the transect lines and at the monitoring well locations at the end of May.
Spring and early summer vegetation should be out by that time and we will be able to
determine any residual stress in the vegetation from the drought conditions of 2007. We
expect to begin dewatering operations in the quarry pit by late March.
Based on our continued monitoring this winter and the amount of rain we receive
in February and March, we will be able to determine whether the baseline water table has
recovered any by that time. Furthermore, we should be able to determine by June
whether the initial mine dewatering is having any additional impact on the water
conditions in the drain.

APPENDIX "A"
Operation and Monitoring Plan for Mine
Dewatering Adjoining Wetlands
Little River Stone, LLC — Seagrove Quarry

Operation and Monitoring Plan for
Mine Dewatering Adjoining Wetlands
Little River Stone, LLC - Seagrove Quarry
COC No. NCG020695
Montgomery County
February 12, 2007
INTODUCTION
As issued by the Division of Water Quality of the NC Dept. of Environment and
Natural Resources, General Permit No. NCG020000 - COC NCG020695, for the
Seagrove Quarry of Little River Stone, LLC, requires the preparation and implementation
of an Operation and Monitoring Plan for the protection of adjoining wetlands due to the
potential of draining them as a result of pit dewatering (Section C-1). The purpose of this
document is to lay out a plan for monitoring groundwater level and surface water
hydrology in the adjoining wetlands and a planned strategy for maintaining the wetland
hydrology should the monitoring plan show adverse effects from the mine dewatering.
DESCRIPTION OF WETLANDS
Attached is a copy of the drawing, "Site Plan for NPDES Permit Application"
which shows the wetland drain under consideration, along with the 50' setback required
by NCDENR, Division of Land Resources, Land Quality Section for issuance of the mine
permit. The wetland drain is typical of small spring and runoff fed drains found in this
hilly region of the state and consists of a roughly 2' wide by 6 to 12" deep channel
meandering in an easterly direction between steep side banks, with generally 2'-5' wide
associated wetlands on either side and less than 20'-wide associated wetlands found at a
few intervals where the terrain flattens out. The channel gradient falls rather steeply (50'
or so) over the first 800' from its head and then turns and flows in a southerly direction
another 300', more or less parallel to the Little River, before discharging into an old cut
off the main river body. The fall over this last section is approximately ten feet.
The flow in the drain is highest during the winter months both due to the usually
heavier rainfall, the higher flows produced from springs along the run caused by higher
groundwater table, and the minimal take up of water from the soil due to dormant trees
and plants. During the main summer months of July and August, the drain will largely
dry up except after periods of rainfall.
DESCRIPTION OF CURRENT PLANS FOR DEVELOPMENT ADJOINING
WETLANDS
The attached drawing, "Site Plan for NPDES Permit Application', shows the
plans for development of areas adjoining the wetlands. Along the north side of the first
500' or so of the drain, overburden from the proposed quarry has been placed and formed
into a series of settling basins for process wastewater from the stone washing process.

The processing plant site will sit at the head of the drain. It is felt that the drain will see
little if any impacts to its groundwater hydrology from this development. Furthermore,
there should be little if any impacts to the surface water hydrology, since the drainage
area feeding the drain will be approximately the same. The plant area sediment basin
(#2) should benefit the wetland area by helping ease the erosive effects of runoff since it
will collect the runoff from the contributing area and release it over time into the drain.
Initially the area to the south of the drain was to be all incorporated into the
quarry area for excavation and dewatering. More recent drilling on the site and ongoing
overburden removal operations have created a need to change this plan. Currently, the
development plan calls for an area approximately 100'-150' wide along the wetlands
offset on this south side of the drain to be used for overburden disposal. This will create
an additional buffer area in which the groundwater hydrology will not be affected, which
should lessen any impacts to the groundwater hydrology in the drain. In addition, it will
lessen the amount of land removed from the area of runoff contributory to the drain,
which will lessen the potential impacts to the surface water hydrology of the drain.
Runoff from the overburden area will be channeled through sediment traps as required.
GROUNDWATER HYDROLOGY MO RING
In order to determine any impacts to the groundwater hydrology in the wetland
drain, Little River Stone proposes to install three monitoring wells in the wetlands area
along the drain in the approximate locations shown on the attached drawing, "Site Plan
for NPDES Permit Application" as modified.
These wells will be constructed by digging or drilling a 6" diameter hole to a
depth of 3' into the ground, backfilling the hole with 6" of NC57 stone, installing a 3'
length of 2" diameter PVC pipe drilled with 12- 1/4" diameter holes per foot over the
lower 2.5' in the center of the hole, and backfilling around the pipe with NC 57 stone. A
mortar collar 12" in diameter and 3" thick will be poured at ground level to keep surface
water out of the hole. The top of the 2" pipe will be 6" above ground level and will be
capped with a 2" PVC cap that is removable for checking water level.
Groundwater level monitoring will be done twice monthly and the results
submitted quarterly along with a report summarizing the results and indicating any
apparent impacts to groundwater hydrology by the quarry dewatering process.
SURFACE WATER HYDROLOGY MONITORING
In order to determine any impacts to the surface water hydrology in the wetland
drain, Little River Stone proposes to set up three transect lines across the wetlands area
along the drain in the approximate Iocations shown on the attached drawing, "Site Plan
for NPDES Permit Application" as modified.
The drain cross-section in square feet at each location will be measured and
recorded. This section area will be checked periodically to insure that the channel section

has not changed due to erosion. The flow, in cubic feet per second (cfs), at each point
will be estimated by measuring the flow velocity, in feet per second (fps), during each
measurement and applying this velocity to the pre -determined cross -sectional area.
Flow in the drain will be measured twice monthly at each location at the same
time the above -referenced monitoring wells are read. The results of the flow
measurements will be submitted quarterly along with a report summarizing the results
and indicating any apparent impacts to the surface water hydrology by the quarry
dewatering process.
VEGETATION MONITORING
In order to monitor the overall "health" of the wetlands system, the existing
vegetation along the three transect lines will be generally documented as to kind and size.
Initial digital photos will be taken along the transect lines. The status of the vegetation
will be checked twice each year (spring and fall), new photos will be taken, and this
information submitted along with the groundwater and surface water hydrology
monitoring reports for that particular quarter.
ACTION PLANS IF ADVERSE EUPACTS_ARE INDICATED
Though impacts to the wetlands drain are not expected due to the buffer areas to
be left around the area, if adverse impacts to the groundwater hydrology, surface water
hydrology, or wetlands vegetation are indicated at any time during the life of the permit,
plans for mitigating these impacts will be developed as warranted by the degree and
character of the specific impacts.
Mitigation efforts will include but not be limited to the modification of pit
dewatering amounts and schedules, as well as potentially modifying the mine plan.
Little River Stone expects that any adverse impacts to the wetlands can be overcome
simply by diverting a small portion of the pit dewatering when it is suitably clean through
one or more small perforated discharge pipes along the drain. When the dewatering
pump is operating, a small amount of water would feed gently out onto the slopes in a
spreading pattern above the drain. The bulk of this water would soak into the soil and
show up in the drain as the areas are re -saturated. This action, in association with
continued surface water runoff into the drain, should reverse any adverse impacts caused
by quarry dewatering.
Under the final reclamation plan for the quarry, a lake is proposed. This lake will
provide water to feed any existing natural underground water courses that may be
disturbed by the quarrying and replenish the wetland drain as required to maintain it
going forward after mining is completed.

IMPLEMENTATION OF PLAN
Once this Operation and Monitoring Plan has been approved by the Division of
Water Quality, Little River Stone will have the plan fully implemented within 30 days.
The first quarterly monitoring report will be submitted within 120 clays of approval of the
Plan by DWQ. Subsequent monitoring reports will be submitted within 90 clays, or 30
days after the end of the monitoring period.

Operation and Monitgring Plan fqr
Mine Dewatering Adioiging Wetlands
Little River Stone, LLC - Seagrove Quarry
COC No. NCG020695
Montgomery County
February 12, 2007
As issued by the Division of Water Quality of the NC Dept. of Environment and
Natural Resources, General Permit No. NCGO20000 - COC NCG020695, for the
Seagrove Quarry of Little River Stone, LLC, requires the preparation and implementation
of an Operation and Monitoring Plan for the protection of adjoining wetlands due to the
potential of draining them as a result of pit dewatering (Section C-1). The purpose of this
document is to lay out a plan for monitoring groundwater level and surface water
hydrology in the adjoining wetlands and a planned strategy for maintaining the wetland
hydrology should the monitoring plan show adverse effects from the mine dewatering.
DESCRIPTION OF WETLANDS
Attached is a copy of the drawing, "Site Plan for NPDES Permit Application"
which shows the wetland drain under consideration, along with the 50' setback required
by NCDENR, Division of Land Resources, Land Quality Section for issuance of the mine
permit. The wetland drain is typical of small spring and runoff fed drains found in this
hilly region of the state and consists of a roughly 2' wide by 6" to 12" deep channel
meandering in an easterly direction between steep side banks, with generally 2'-5' wide
associated wetlands on either side and less than 20'-wide associated wetlands found at a
few intervals where the terrain flattens out. The channel gradient falls rather steeply (50'
or so) over the first 800' from its head and then turns and flows in a southerly direction
another 300', more or less parallel to the Little River, before discharging into an old cut
off the main river body. The fall over this last section is approximately ten feet.
The flow in the drain is highest during the winter months both due to the usually
heavier rainfall, the higher flows produced from springs along the run caused by higher
groundwater table, and the minimal take up of water from the soil due to dormant trees
and plants. During the main summer months of July and August, the drain will largely
dry up except after periods of rainfall.
DESCRIPTION OF CURRENT PLANS_ FOR DEVELOPMENT ADJOINING
WETLANDS
The attached drawing, "Site Plan for NPDES Permit Application", shows the
plans for development of areas adjoining the wetlands. Along the north side of the first
500' or so of the drain, overburden from the proposed quarry has been placed and formed
into a series of settling basins for process wastewater from the stone washing process.

The processing plant site will sit at the head of the drain. It is felt that the drain will see
little if any impacts to its groundwater hydrology from this development. Furthermore,
there should be little if any impacts to the surface water hydrology, since the drainage
area feeding the drain will be approximately the same. The plant area sediment basin
(#2) should benefit the wetland area by helping ease the erosive effects of runoff since it
will collect the runoff from the contributing area and release it over time into the drain.
Initially the area to the south of the drain was to be all incorporated into the
quarry area for excavation and dewatering. More recent drilling on the site and ongoing
overburden removal operations have created a need to change this plan. Currently, the
development plan calls for an area approximately 100'-150' wide along the wetlands
offset on this south side of the drain to be used for overburden disposal. This will create
an additional buffer area in which the groundwater hydrology will not be affected, which
should lessen any impacts to the groundwater hydrology in the drain. In addition, it will
lessen the amount of land removed from the area of runoff contributory to the drain,
which will lessen the potential impacts to the surface water hydrology of the drain.
Runoff from the overburden area will be channeled through sediment traps as required.
GROUNDWATER HYDROLOGY MONFTORING
In order to determine any impacts to the groundwater hydrology in the wetland
drain, Little River Stone proposes to install three monitoring wells in the wetlands area
along the drain in the approximate locations shown on the attached drawing, "Site Plan
for NPDES Permit Application" as modified.
These wells will be constructed by digging or drilling a 6" diameter hole to a
depth of 3' into the ground, backfilling the hole with 6" of NC57 stone, installing a 3'
length of 2" diameter PVC pipe drilled with 12- '/a" diameter holes per foot over the
lower 2.5' in the center of the hole, and backfilling around the pipe with NC 57 stone. A
mortar collar 12" in diameter and 3" thick will be poured at ground level to keep surface
water out of the hole. The top of the 2" pipe will be 6" above ground level and will be
capped with a 2" PVC cap that is removable for checking water level.
Groundwater level monitoring will be done twice monthly and the results
submitted quarterly along with a report summarizing the results and indicating any
apparent impacts to groundwater hydrology by the quarry dewatering process.
SURFACE WATER HYDROLOGY MONITORING
In order to determine any impacts to the surface water hydrology in the wetland
drain, Little River Stone proposes to set up three transect lines across the wetlands area
along the drain in the approximate locations shown on the attached drawing, "Site Plan
for NPDES Permit Application" as modified.
The drain cross-section in square feet at each location will be measured and
recorded. This section area will be checked periodically to insure that the channel section
2

1 T z T Wo T I T -, -, i','.

has not changed due to erosion. The flow, in cubic feet per second (cfs), at each point
will be estimated by measuring the flow velocity, in feet per second (fps), during each
measurement and applying this velocity to the pre -determined cross -sectional area.
Flow in the drain will be measured twice monthly at each location at the same
time the above -referenced monitoring wells are read. The results of the flow
measurements will be submitted quarterly along with a report summarizing the results
and indicating any apparent impacts to the surface water hydrology by the quarry
dewatering process.
VEGETATION MONITORING
In order to monitor the overall "health" of the wetlands system, the existing
vegetation along the three transect lines will be generally documented as to kind and size.
Initial digital photos will be taken along the transect lines. The status of the vegetation
will be checked twice each year (spring and fall), new photos will be taken, and this
information submitted along with the groundwater and surface water hydrology
monitoring reports for that particular quarter.
ACTION PLANS IF ADVERSE IMPACTS ARE INDICATED
Though impacts to the wetlands drain are not expected due to the buffer areas to
be left around the area, if adverse impacts to the groundwater hydrology, surface water
hydrology, or wetlands vegetation are indicated at any time during the life of the permit,
plans for mitigating these impacts will be developed as warranted by the degree and
character of the specific impacts.
Mitigation efforts will include but not be limited to the modification of pit
dewatering amounts and schedules, as well as potentially modifying the mine plan.
Little River Stone expects that any adverse impacts to the wetlands can be overcome
simply by diverting a small portion of the pit dewatering when it is suitably clean through
one or more small perforated discharge pipes along the drain. When the dewatering
pump is operating, a small amount of water would feed gently out onto the slopes in a
spreading pattern above the drain. The bulk of this water would soak into the soil and
show up in the drain as the areas are re -saturated. This action, in association with
continued surface water runoff into the drain, should reverse any adverse impacts caused
by quarry dewatering.
Under the final reclamation plan for the quarry, a lake is proposed. This lake will
provide water to feed any existing natural underground water courses that may be
disturbed by the quarrying and replenish the wetland drain as required to maintain it
going forward after mining is completed.

spreading pattern above the drain. The bulk of this water would soak into the soil and
show up in the drain as the areas are re -saturated. This action, in association with
continued surface water runoff into the drain, should reverse any adverse impacts caused
by quarry dewatering.
Under the final reclamation plan for the quarry, a lake is proposed. This lake will
provide water to feed any existing natural underground water courses that may be
disturbed by the quarrying and replenish the wetland drain as required to maintain it
going forward after mining is completed.

To: Bethany Georgoulias<[e-mail]>
Hi Bethany! As you know, I conducted a site visit to the proposed Seagrove Quarry
in Montgomery County last week. After speaking to the engineer, Mr. Howiler, I feel
pretty confident with the stormwater and process water control measures they have
proposed. Also, since Mr. Howiler is very familiar with the general permit, has
worked with other mining companies and will be retained to perform proper monitoring
and compliance, I recommend proceeding with issuance of their certificate of
coverage under the NCG020000 general permit. As I mentioned to you last week, Mr.
Howiler did express that some wetlands are adjacent to what will be the active
quarry pit. Although I'm not convinced that there may be wetland impacts due to
mine dewatering, you may want Co include in their COC that they should provide the
regional office with some type of O&M plan if there is the potential for impacts.
If you need any further comments, please contact me.
On another topic, can DWQ rescind permit coverage for an industry that we know is no
longer in operation. Specifically, we have discovered that one of our permitted
facilities (Woodard rnc-NCG180216) has been abandoned. It appears that the facility
has been shut down for a while and we would probably be unable to contact anyone
with the company to request that they submit a rescission request letter. Can the
Division go ahead and rescind without a request letter from the permittee?
Thanks,
Mike

Dear Ms. Georgoulias:
We are pleased to submit the enclosed revised engineering information as we
discussed by phone today on behalf of Little River Stone, LLC pertaining to their request
for coverage of the proposed Seagrove Quarry under the NPDES General Permit for
Mineral Mining (NCG020000).
Specifically, please find the following items enclosed:
1) three copies of an attachment to the NOI as modified to make Section 15
agree with the process settling basin system design notes as to basin
retention times and also to show trapping efficiency calculations for each
individual basin,
2) three copies of "Design Calculations for Process Wastewater Settling Basins"
as revised to more correctly depict individual basin holding times, based on
both normal operating conditions, as well as when one of the primary basins
is taken out of service for settled solids removal.
We trust that this submittal provides you with all the additional information you
need to complete processing this NOI request; however, should you need additional
information or have any questions, please contact the writer.
Sincerely,
Howiler & Associates

N01 for Seagrove Quarry
Subject: N01 for Seagrove Quarry

To: Mike Lawyer <[e-mail]>
Mike,
NO I aff Nc.0 020GR5--
We've received an NOI from Little River Stone, LLC for an NCG02 mining
stormwater/wastewater permit for their Seagrove Quarry. They've already received
their Mining Permit (# 62-41) from DLR on June 15, 2006.
I'm only attaching the map to this e-mail because I'm sending a hard copy of the
package to you (includes site plan, NOI, treatment system calcs, etc.) They are
proposing a closed -loop recycle system for their process wastewater, but will
discharge mine dewatering water and•stormwater. [Technically an ATC won't be required
for this one since it's a crushed stone quarry and their recycle system is
closed -loop, but I do intend to review their process WW treatment system calcs before
approving the COC.] They're proposing to use DAMS for flocculation as needed, so I
plan to explain they'll have to refer to the list of approved products in NC.
The operation will discharge to a couple of tribs to the Little River, in a segment
designated as C waters in the Yadkin Basin. From the site plan, it looks like there
are wetlands in the vicinity, which is another reason I wanted to send a copy of the
package for you to review.
Does the Fayetteville Regional Office have any concerns about issuing this facility a
COC for this general permit, and is there tfie potential to impact wetlands nearby?
We'll require an 0&M plan prior to operation if that's the case (which I'll put in the
letter). Normally if we don't receive any objections we issue the COC in 30 days, but
I usually hold off on mining permits, especially if wetlands may be affected. Just
let me know when you've had a chance to look through the application.
Thanks!

Re: NPDES Permit Application
Little River Stone, LLC - Seagrove Quarry
Montgomery County
Dear Sirs:
LL OWNS
OCT 1 1 2oU6
UENR - WATER QUALITY
fetlands & Stommater Branch
We are pleased to submit the enclosed Notice of Intent for coverage of the
proposed Seagrove Quarry under the NPDES General Permit for Mineral Mining
(NCG020000) on behalf of Little River Stone, LLC.
In support of this Notice of Intent, please find the following items enclosed:
1) three copies of the completed Notice of Intent,
2) three copies of an attachment to the NOI,
3) three copies of "Site Plan for NPDES Permit Application" (Dwg. No. 1 of 2),
4) three copies of "Water Flow Schematic for NPDES Permit Application" (Dwg.
No. 2 of 2),
5) three copies of "Design Calculations for Process Wastewater Settling
Basins",
6) one copy of the approved mining permit for the quarry,
7) three copies of Montgomery County .highway map showing the quarry
location,
8) and a check for $80.00 made payable to NCDENR to cover .the permit
application processing fee.
As we interpret the text of the general permit, specifically Part III, Section C-3,
"Overflow From a Closed Loop Process Wastewater Recycle System Designed to
Operate With Minimum of Two -Feet of Freeboard", "authorization to construct and
operate requirements (Part 11, Sections A and B) are not applicable to this type of
process wastewater operation". The process wastewater basin system is designed to
limit the amount of water entering the. system to makeup water that is added to operate
the system at or below the two feet of freeboard and/or precipitation that falls directly into
the system as required by this. section. The system is also designed to exclude
stormwater runoff from entering the system as required by this section. Therefore, it is
our understanding that an Authorization to Construct and Operate this process
wastewater system is not required and, thus, is not being sought.

Furthermore, in accordance with- this section of the General Permit, it is our
understanding that no analytical monitoring will be required for the overflow from this
system because it is a closed loop recycle system designed to operate with two feet of
freeboard.
Design calculations as shown in item 5) above are included in this package that
show that the process wastewater settling basin system will hold all stormwater falling on
it as a result of the 100-yr., 24-hr. storm event without discharging.
In order to insure the quality of the water returned to the plant from the process
wastewater settling basin system, as well as any discharge from the old quarry through
Outfall 001, we are requesting approval for the use of polymeric flocculants at this
operation. Please note item 15) of the NOI form and accompanying attachment.
We trust that this submittal provides you with all the information to process this
NOI request; however, should you need additional information or have any questions,
please contact the writer.
Sincerely,
Howiler & Associates

Attachment to Notice of Intent to Discharge Under NCG020000
By Little River Stone, LLC - Seagrove Quarry
September 29, 2006
(See attached Site Map and Water Flow Schematic for further explanation)
6) Minerals mined:
The stone to be mined at this operation has been identified as a metamorphic
quartz schist; however, it is likely better characterized as a non -foliated metamorphic
quartzite or a metavolcanic tuff.
7) Discharge Points:
There will be two discharge points for this operation as follows:
1) Outfall 001 will be the intermittent discharge from an old quarry pit on the site to
a tributary to Little River immediately upstream of the river_ This discharge will consist
of various combinations of: (a) mine dewatering, (b) stormwater, and (c) process
wastewater. Since its primary and controlling component (from monitoring standpoint)
will be mine dewatering, it will be sampled and reported as such.
(a) All groundwater and stormwater runoff collected in the quarry pit will receive
primary treatment in a sump that will be maintained below the lowest pit floor level.
This mine dewatering will then be pumped as required to either the closed loop process
water system as makeup water or to the old quarry pit that will serve as secondary
treatment for this water.
(b) Stormwater runoff from the entrance road and shop area will be routed to a
sediment basin along the quarry entrance road for primary treatment. This sediment
basin will discharge to the old quarry pit which will serve as secondary treatment for this
stormwater.
(c) The process wastewater system is designed as a closed loop recycle system
that will only overflow during a rainfall event exceeding the 10-year, 24-hr. rainfall
event. The system will consist of two settling basins and a combination settling basin and
fresh water basin which will contain the plant fresh water pump that will supply the
aggregate washing operation. Influent to the system will consist of return water from the
aggregate washing operation, rainfall that falls directly into the system, and any makeup
water from the quarry pit dewatering operation as indicated above. Any overflow from
this system during rainfall events exceeding the 10-yr., 24-hr. storm will be routed to the
old quarry pit via a pipe outfall.
A pump will be installed in this old quarry pit and it will serve as the backup for
the fresh water makeup system during dry periods when there is little water collected in
the active quarry pit. It will also serve to fill the water truck that will distribute water
over the stockpile area, dirt haul roads, etc. in order to control fugitive dust emissions
from these sources.

2) SDO 001 will be the discharge from a sediment basin that will treat stormwater
runoff from the plant and product stockpile area and release it to a small tributary to Little
River.
11) BMP's for stormwater control:
See 7) above, which covers the installation of permanent sediment basins for
treatment of stormwater from the plant entrance road, shop area, and plant and product
stockpile area, as well as stormwater generated within the quarry pit. The clearing of
areas ahead of quarry development will be minimized in order to minimize the amount of
land exposed to erosive conditions. These limited areas of disturbance will drain into the
quarry pit or through erosion and sediment control devices such as brush barriers, silt
fencing, sediment traps, etc. onto undisturbed portions of the site.
15) Process wastewater treatment system:
a) Process wastewater will be treated by primary and secondary sedimentation in a
series of settling basins. Two basins will provide primary sedimentation. Wash water
outfall piping from the processing plant will be designed so that either of the two basins
will operate while the other is being cleaned out. Overflow from the two primary basins
will be routed via pipes to the secondary settling basin which will also serve as the
processing plant fresh water basin. A pump in this basin will return water to the wash
plant for reuse. Makeup water as needed to overcome system losses to evaporation and
into the finished products will be provided from the mine dewatering pump as indicated
above.
The total active volume in the settling basin system is 1,087,000 gallons. At a
pumping rate of 800 gpm (1.78 cfs) to the wash plant, the retention time in the basin
system will be 1358 minutes, or 22.6 hours.
The surface area at normal water level in the basins will be approximately 21,500
sf . Surface area to basin outflow ratio equals:
21,500 sf11.78 cfs = 12,078 sf/cfs
The D15 size of material entering the basin system from the washing operation = +/-
0.045 mm (325 mesh). The settling velocity of this particle V1s = +/- 0.003 fps.
(Qp.) I (V15)(Surface Area) _ (1.78 cfs) I (0.003 fps)(0.493 acs) = 1203
Trapping efficiency for D15 particles = +/-94%
(Reference "Engineering Aids and Design Guidelines for Control of Sediment" by John C. Hayes
and Billy J. Barfield)
These retention time and surface area to outflow parameters indicate that, with
continuing removal of the accumulated solids as required, the basin system will remove
solids with adequate efficiency to allow the water to be used for recycling.

b) In order to insure that a high quality of return water is available at all times and
that, should the process wastewater basins overflow as the result of a storm event, the
overflow will be as clean as possible, the permittee proposes to use a polymeric
flocculent to flocculate additional suspended solids on an as needed basis. The polymer
used in the non -discharge, closed loop recycle process wastewater settling basin system
will be:
(1) Nalco Car -Floc 9856 Plus;
(2) RMC (Rochester Midland Corp.) MIDFLOC 1316E, MIDFLOC
1320L, and MIDFLOC 1321L; or
(3) Kemira Chemicals INDUSET 246
Likewise, to insure a high quality effluent from Outfall 001, the permittee
proposes to add one of the following polymeric flocculents to the mine dewatering
entering the old quarry pit on an as needed basis.
(4) Nalco En -Act 7883
(5) RMC (Rochester Midland Corp.) MIDFLOC 1309L
(6) Kemira Chemicals INDUSET 246
All of these products have a proven track record of low toxicity due to their
chemical makeup, as well as their resultant behavior and breakdown in the ponds. All
are used extensively in the mining industry. The permittee will determine the product
which yields the best combination of pricing and performance based on bench tests at
startup of the quarry and subsequently provide DENR with the proposed dosage rates and
daily quantity of use.
e) Design calculations are attached to show that the basin system will overflow only
during rainfall events exceeding the 10-yr., 24-hr. rainfall event. Indeed, the calculations
show that the basin system will not overflow even during the 100-yr. storm event. An
emergency overflow pipe will be installed to allow stormwater accumulation from an
event exceeding the I00-yr_ storm event to be safely channeled to the old quarry pit. Any
excess accumulation of water in this old pit will overflow through Outfall 001.

I Desicn of Process Wastewater Setti inn Basins
Reference: NC Erosion and Sedimentation Control Planning and Design Manual
A) Holding Times
Primary settling basin "A" has the following dimensions:
Area at normal water level (2' freeboard to emergency overflow) = 7715 sf
w11:1 side slopes and a total depth of 12', bottom area: 2724 sf
at normal water level, water volume = 370,900 gallons
Wastewater flow = 800 gpm (1.78 cfs) wastewater flow, then holding time = 7.7 hrs.
Primary settling basin "B" has the following dimensions:
Area at normal water level (2' freeboard to emergency overflow) = 7134 sf
w11:1 side slopes and a total depth of 12', bottom area: 2502 sf
at normal water level, water volume = 342,400 gallons
Wastewater flow = 800 gpm (1.78 cfs) wastewater flow, then holding time = 7.1 hrs.
Secondary settling/fresh water basin has the following dimensions:
Area at normal water level (3' freeboard to emergency overflow) = 6706 sf
w/ 1:1 side slopes and a total depth of 12', bottom area: 2283 sf
at normal water level, water volume = 319,400 gallons
Wastewater flow = 800 gpm (1.78 cfs) wastewater flow, then holding time = 667 hrs.
Total Holding Time = 21.5 hrs.
With basins half -full of settled solids, Total Holding Time = 11.3 hrs.
B) Check retention for 10-yr., 244hr. storm event inflow to basin system
1) - Calculate Peak Flow, Q,o, inflow to basins for the contributing

b) Determine runoff depth
From Figure 8.031, for Montgomery County, the rainfall amount
for the 10-year, 24-hr. storm at site. P = 5.3 inches
Ultimate Soil Storage Capacity = S = (1000/CN) - 10 = 1.07 inches
Runoff depth, Qr = (P-0.2S)z/(P+0.8S) = 4.20 inches
c) Determine peak rate of runoff for the design storm by adjusting for
watershed shape
Using the equation L = 209'a"°-6 ,where (L) is the hydraulic length and (a) is the drainage area
the equivalent drainage area is therefore, a = 0.9 acres
From figure 8.03p, 2% slope, CN = 90; peak rate of runoff = 1.8 Winch
Q, = Peak Rate Runoff • Qr = 7.6 cfs
Q2 = Q4 "Actual Area/Equiv Area = 14.6 cfs
d) Adjust peak discharge rate Q2 for percent Impervious area (none, therefore factor
=1) and percent hydraulic length modified:
From figure 8.03r, for CN = 90 and % length modified = 0
hydraulic length adjustment factor 1.00
therefore, Q3 = Qz " adj factor = 14.6 cfs
e) Adjust peak discharge rate 03 for average watershed slope
By interpolation from Table 8.03d, for avg. slope = 2.0 and drainage area = 1.8
adjustment factor - 1.06
Q4 = Q3' adj. Factor = 15.5 cfs
f) Adjust peak discharge Q4 for surface ponding
From Table 8.03e, for Q10 and ponding ratio = 3.7 at design point
QPio,u = Q4 'adj. Factor=
g) - Compute time to peak for 10-yr storm
TP = (43.5 " 4' A) / QA = 32 min
Adjustment factor = 0.66
Adjustment factor =

We see that maximum stage will be 1.18' (elevation = 95.68) above normal water level and 0.82' below
emergency spillway elevation (elevation = 96.50) for the 10-yr, 24-hr storm inflow to the basin. Bank
full elevation is 1.32' above this maximum stage. For a dug pond, this Is okay; however actual high
elevation around pond is 1' higher, so freeboard will actually be 2.37.
C) Check 100- . 24-hr. storm event inflow to basin Iystem and size outfall pipe
1) - Calculate Peak Flow, 040, Inflow to basins for the contributing
drainage area using SCS TR- 5, and flood routing
b) From Figure 8.03j, for Montgomery County, the rainfall
amount for the 100-year, 24-hr. storm at site, P = 7.7 inches
Ultimate Soil Storage Capacity = S = (1000/CN) -10 = 1.07 inches
Runoff depth, Q, = (P-0.2S)2/(P+0.8S) = 6.55 inches
c) Determine peak rate of runoff for the design storm by adjusting for

Using the equation L = 209'aAQ6 ,where (L) is the hydraulic length and (a) is the drainage area
the equivalent drainage area is therefore, a = 0.9 acres
From figure 8.03p, 2% slope, CN = 90; peak rate of runoff = 1.8 cfs/inch
Q1 = Peak Rate Runoff ' Or = 11.8 cis

We see that maximum stage will be 1.8' above normal water elevation (elev = 595.3) and 0.2' below
emergency overflow (596.5), for the 100yr storm Inflow to the basin. Bank full elevation is 0.7'
above this maximum stage. For a dug pond, this is okay; however actual high elevation around pond
is 1' higher, so freeboard will actually be 1.7'.
2) - Size emergency overflow pipe
Assume maximum outflow at >100-yr. storm = 12.50 cfs 2/3 of 100-yr. storm inflow
(see above) This is VERY conservative
5 = 596.5-588/150' = 0.0567 ft/ft
n = 0.013 RCP or smooth -bore CPP
At 0.0567 ftlft grade, 16' RCP will carry 15.5 cfs flowing full and 12.5 cfs @ depth = 10.5".
Check Available head for Pipe Flow
Checking for inlet, velocity head, and pipeline friction losses:
Total HL = He + H„ + hr = (V/2gXke + 1 + ((29n`L)/R`))
where, ke = 0.6 for straight pipe inlet
A-- 1.23 sf
V=Q/A= 10.16 ft/sec
R = AMP = 1.231(3.14)(1.25) = 0.49
L = 150 ft
HL = 5.61 ft
Available HL = 597.7 - 588.8 = 8.9' > 5.61' OKl
Use 150' of 15" RCP.

Attachment to N to ice of Intent to Discharge Under NCG020000
By Little River Stone, LLC - Seagrove Quarry
September 29, 2006
Modified November 16, 2006
(See attached Site Map and Water Flow Schematic for further explanation)
6) Minerals mined:
The stone to be mined at this operation has been identified as a metamorphic
quartz schist; however, it is likely better characterized as a non -foliated metamorphic
quartzite or a metavolcanic tuff.
7) Discharge Points:
There will be two discharge points for this operation as follows:
1) Outfall 001 will be the intermittent discharge from an old quarry pit on the site to
a tributary to Little River immediately upstream of the river. This discharge will consist
of various combinations of: (a) mine dewatering, (b) stormwater, and (c) process
wastewater. Since its primary and controlling component (from monitoring standpoint)
will be mine dewatering, it will be sampled and reported as such.
(a) All groundwater and stormwater runoff collected in the quarry pit will receive
primary treatment in a sump that will be maintained below the lowest pit floor level.
This mine dewatering will then be pumped as required to either the closed loop process
water system as makeup water or to the old quarry pit that will serve as secondary
treatment for this water.
(b) Stormwater runoff from the entrance road and shop area will be routed to a
sediment basin along the quarry entrance road for primary treatment. This sediment
basin will discharge to the old quarry pit which will serve as secondary treatment for this
stormwater.
(c) The process wastewater system is designed as a closed loop recycle system
that will only overflow during a rainfall event exceeding the 10-year, 24-hr. rainfall
event. The system will consist of two settling basins and a combination settling basin and
fresh water basin which will contain the plant fresh water pump that will supply the
aggregate washing operation. Influent to the system will consist of return water from the
aggregate washing operation, rainfall that falls directly into the system, and any makeup
water from the quarry pit dewatering operation as indicated above. Any overflow from
this system during rainfall events exceeding the 10-yr., 24-hr. storm will be routed to the
old quarry pit via a pipe outfall.
A pump will be installed in this old quarry pit and it will serve as the backup for
the fresh water makeup system during dry periods when there is little water collected in
the active quarry pit. It will also serve to fill the water truck that will distribute water
over the stockpile area, dirt haul roads, etc. in order to control fugitive dust emissions
from these sources.

2) SDO 001 will be the discharge from a sediment basin that will treat stormwater .
runoff from the plant and product stockpile area and release it to a small tributary to Little
River.
11) BW's for stormwater control:
See 7) above, which covers the installation of permanent sediment basins for
treatment of stormwater from the plant entrance road, shop area, and plant and product
stockpile area, as well as stormwater generated within the quarry pit. The clearing of
areas ahead of quarry development will be minimized in order to minimize the amount of
land exposed to erosive conditions. These limited areas of disturbance will drain into the
quarry pit or through erosion and sediment control devices such as brush barriers, silt
fencing, sediment traps, etc. onto undisturbed portions of the site.
15) Process wastewater treatment system:
a) Process wastewater will be treated by primary and secondary sedimentation in a
series of settling basins. Two basins will provide primary sedimentation under normal
conditions. Wash water outfall piping from the processing plant will be designed so that
either of the two basins will operate while the other is being cleaned out. Overflow from
the two primary basins will be routed via pipes to the secondary settling basin which will
also serve as the processing plant fresh water basin. A pump in this basin will return
water to the wash plant for reuse. Makeup water as needed to overcome system losses to
evaporation and into the finished products will be provided from the mine dewatering
pump as indicated above.
The total active volume in the settling basin system is 1,032,700 gallons. At a
pumping rate of 800 gpm (1.78 cfs) to the wash plant, under normal operating conditions
with both primary basins in service (400 gpm in each primary basin and 800 gpm in
secondary/fresh water basin), the retention time in the basin system will be 36.3 hours as
shown in the attached design notes.
The surface area at normal water level in each basin and the surface area to basin
outflow ratio will be as follows under normal operating conditions:
Basin surface area Surface area to outflow ratio
Primary "A" 7715 sf = 0.177 acs 8668 sf/cfs
Primary "B" 7134 sf = 0.164 acs 8016 sf/cfs
Secondary/F.W. 6706 sf = 0.154 acs 3767 sf/cfs
The Di5 size of material entering the basin system from the washing operation = +/-
0.045 mm (325 mesh). The settling velocity of this particle V15 = +/- 0.003 fps. For
each basin, the ratio, (Qp.) / (V15)(Surface Area), and the resulting trapping efficiency are
as follows:
Ratio Trapping Efficiency
Primary "A" 1676 +94%
Primary "B" 1809 +94%
Secondary/F.W. 3853 +92%

Under normal operating conditions, the overall system trapping efficiency for D15
particles = +/-94%. This will be somewhat diminished when one of the primary basins is
being cleaned but will still be in the 92% range.
(Reference "Engineering Aids and Design Guidelines for Control of Sediment" by John C. Hayes
and Billy J. Barfield)
These retention time and surface area to outflow parameters indicate that, with
continuing removal of the accumulated solids as required, the basin system will remove
solids with adequate efficiency to allow the water to be used for recycling.
b) In order to insure that a high quality of return water is available at all times and
that, should the process wastewater basins overflow as the result of storm event, the
overflow will be as clean as possible, the permittee proposes to use a polymeric
flocculent to flocculate additional suspended solids on an as needed basis. The polymer
used in the non -discharge, closed loop recycle process wastewater settling basin system
will be:
(1) Nalco Cat -Floc 9856 Plus;
(2) RMC (Rochester Midland Corp.) MIDFLOC 1316E, MIDFLOC
1320L, and MIDFLOC 1321L; or
(3) Kemira Chemicals INDUSET 246
Likewise, to insure a high quality effluent from Outfall 001, the permittee
proposes to add one of the following polymeric flocculents to the mine dewatering
entering the old quarry pit on an as needed basis.
(4) Nalco En -Act 7883
(5) RMC (Rochester Midland Corp.) MIDFLOC 1309L
(6) Kemira Chemicals IlVDUSET 246
All of these products have a proven track record of low toxicity due to their
chemical makeup, as well as their resultant behavior and breakdown in the ponds. All
are used extensively in the mining industry. The permittee will determine the product
which yields the best combination of pricing and performance based on bench tests at
startup of the quarry and subsequently provide DENR with the proposed dosage rates and
daily quantity of use.
c) Design calculations are attached to show that the basin system will overflow only
during rainfall events exceeding the 10-yr., 24-hr. rainfall event. Indeed, the calculations
show that the basin system will not overflow even during the 100-yr. storm event. An
emergency overflow pipe will be installed to allow stormwater accumulation from an
event exceeding the 100-yr. storm event to be safely channeled to the old quarry pit. Any
excess accumulation of water in this old pit will overflow through Outfall 001.

b) Determine runoff depth
From Figure 8.03j, for Montgomery County, the rainfall amount
for the 10-year, 24-hr. storm at site, P = 5.3 inches
Ultimate Soil Storage Capacity = S = (1000/CN) - 10 = 1.07 inches
Runoff depth, Q, = (P-0.2S)2/(P+0.8S) = 4.20 inches
c) Determine peak rate of runoff for the design storm by adjusting for
watershed shape
Using the equation L = 209*a"°3 where (L) is the hydraulic length and (a) is the drainage area
the equivalent drainage area is therefore, a = 0.9 acres
From figure 8.03p, 2% slope, CN = 90; peak rate of runoff = 1.8 cfstinch
Q, = Peak Rate Runoff * Qr = 7.6 cfs
Q2 = Q, * Actual Area/Equiv Area = 14.6 cfs
d) Adjust peak discharge rate 02 for percent impervious area (none, therefore factor =1)
and percent hydraulic length modified:
From figure 8.03r, for CN = 90 and % length modified = 0
hydraulic length adjustment factor 1.00
therefore, Q3 = Q2 * adj factor = 14.6 cfs
e) Adjust peak discharge rate Q3 for average watershed slope
By interpolation from Table 8.03d, for avg. slope = 2.0 and drainage area =
adjustment factor : 1.06
Q4 = Q3* adj. Factor = 15.5 cfs
f) Adjust peak discharge Q4 for surface ponding

Determine KS and b using known information from two contour
levels, near max. water level =2' and mid -depth, elev. = 1'
b = In(S21S1)lln(Z2/Zt) = In(48222/23167) / In(211) = 1.058
Kg = S2 / (Z2)b = 48222/ (2)111.058 = 23167
Check constants using Z = (S/Ks)tm
At depth =1', 1' = (23167123167)11-' = 1.0 ft
Therefore, since the result is within 0.1', we can consider the constants valid.
j) - Perform Short -Cut Routing to determine maximum water elevation and outflow
Based on 10-yr storm hydrograph above, following is the stage -storage -
discharge data developed from short cut flood routing method, assuming
beginning water level is at normal water level, i.e. 2' below emergency

We see that maximum stage will be 1.18' (elevation = 95.68) above normal water level and 0.82' below
emergency spillway elevation (elevation = 96.50) for the 10-yr, 24-hr storm inflow to the basin. Bank
full elevation is 1.32' above this maximum stage. For a dug pond, this is okay; however actual high
elevation around pond is 1' higher, so freeboard will actually be 2.32'.
C) Check 100-yr., 24-hr. storm event inflow to basin system and size outfall pipe
1) - Calculate Peak Flow, Q10, inflow to basins for the contributing
drainage area using SCS TR-55, and flood routing
b) From Figure 8.03j, for Montgomery County, the rainfall
amount for the 100-year, 24-hr. storm at site, P = 7.7 inches
Ultimate Soil Storage Capacity = S = (t00Q/CN) - 10 = 1.07 inches
Runoff depth, Q, = (P-0.2S)2/(P+0.8S) = 6.55 inches
c) Determine Peak rate of runoff for the design storm by adjusting for
watershed shape
Using the equation L = 209'a^°-& where (L) is the hydraulic length and (a) is the drainage area
the equivalent drainage area is therefore, a = 0.9 acres
From figure 8.03p, 2% slope, CN = 90; peak rate of runoff = 1.8 cfs/inch
Q, = Peak Rate Runoff " Qr = 11.8 cfs
Q2 = Q1 " Actual Area/Fquiv Area = 22.8 cfs
d) Adjust peak discharge rate 02 for percent impervious area (none, therefore factor =1)
and percent hydraulic length modified:
From figure 8.03r, for CN = 0 and % length modified = 0
hydraulic length adjustment factor 1.00
therefore, Q3 = Qz ` adj factor = 22.8 cfs
e) Adjust peak discharge rate Q, for average watershed slope
By interpolation from Table 8.03d, for avg. slope = 2.0 and drainage area = 1.8
adjustment factor: 1.06
Q4 = Qs" adj. Factor = 24.2 cfs
f) Adjust peak discharge 04 for surface ponding
From Table 8.03e, for Q10 and ponding ratio = 3.7 at design point
Qp,00,24 = Q4 *adj. Factor =
Adjustment factor = 0.77

We see that maximum stage will be 1.8' above normal water elevation (elev = 596.3) and 0.2' below
emergency overflow (596.5), for the 100-yr storm inflow to the basin. Bank full elevation is 0.7' above
this maximum stage. For a dug pond, this is okay; however actual high elevation around pond is 1'
higher, so freeboard will actually be 1.7'.
2) - Size emergency overflow pipe
Assume maximum outflow at >100-yr. storm = 12.50 cfs 2/3 of 100-yr. storm inflow
(see above) This is VERY conservative
S = 596.5-5381180' = 0.325 ft/ft
n = 0.022 CMP
At 0.325 ft/ft grade, 15" RCP will carry 30 cfs flowing full and 12.5 cfs @ depth = 6.75".
Check Available Head for Pipe Flow
Checking for inlet, velocity head, and pipeline friction losses:
Total HL = Fie + H„ + hs = (V/2g)(ke + 1 + ((29n'L)/R'."))
where, ke = 0.6 for straight pipe inlet
A= 1.23 sf
V=Q/A= 10.16 ft/sec
R = A/WP = 1.23/(3.14)(1.25) = 0.49
L = 200 ft
HL = 14.20 ft
Available HL = 597.7 - 538.8 = 58.9' >1420' OK!
Use 200' of 15" CMP.

Hi Mike,
I'd requested additional info. on the wastewater recycling system talcs for this
quarry, so I'm sending you a hard copy of what we received for the FRO files. I
reviewed those last week, and they look okay, so I think'we can consider their
application complete. Not sure if you've had an opportunity to visit the site yet or
not, but when you do, let me know if wetlands will potentially be impacted. If so,
this site will require an O&M Plan once we issue the permit and before they start
operation.
Hope you had a nice Thanksgiving!

j Mike,
We've received an NOI from Little River Stone, LLC for an NCG02 mining
stormwater/wastewater permit for their Seagrove Quarry. They've already
received their Mining Permit (# 62-91) from DLR on June 15, 2006."---
I'm only attaching the map to this e-mail because I'm sending a hard copy of the
package to you (includes site plan, NOI, treatment system talcs, etc.). They are
proposing a,closed-Loop recycle system for their process wastewater, but will
discharge mine dewatering water and stormwater. [Technically an ATC won't be
required for this one since it's a crushed stone quarry and their recycle system
is closed -loop, but I do intend to.review their process WW treatment system
tales before approving the COC.] They're proposing to use PAMS for flocculation
as needed, so I plan to explain they'll have to refer to the list of approved
products in NC.
The operation will discharge to a couple of tribs to the Little River, in a
segment designated as C waters in the.'Yadkin Basin. From the site plan, it
looks like there are wetlands in the vicinity, which is another reason I wanted
to send a copy of the package for you to "review.
Does the Fayetteville Regional Office have any concerns about issuing this
facility a COC for this general permit, and is there the potential to impact
wetlands nearby? We'll require an O&M plan prior to operation if that's the
case (which I'll put in.the letter)._,Normally if we don'.t receive any
objections we issue the COC in 30 days, but I usually hold off on mining
permits, especially if wetlands may be affected. Just let me know when you've
had a chance to look through the application.
Thanks!

We see that maximum stage will be 1.18' (elevation = 95.68) above normal water level and 0.82' below
emergency spillway elevation (elevation = 96.50) for the 10-yr, 24-hr storm inflow to the basin. Sank
full elevation is 1.32' above this maximum stage. For a dug pond, this is okay, however actual high
elevation around pond is 1' higher, so freeboard will actually be 2.32'.

We see that maximum stage will be 1.8' above normal water elevation (elev = 596.3) and 0.2' below
emergency overflow (596.5), for the 100-yr storm inflow to the basin. Bank full elevation is 0.7' above
this maximum stage. For a dug pond, this is okay; however actual high elevation around pond is 1'
higher, so freeboard will actually be 1.7'.
2) - Size emergency overflow pipe
Assume maximum outflow at >100-yr. storm = 12.50 cfs 2/3 of 100-yr. storm inflow
(see above) This is VERY conservative
S = 596.5-5381180' = 0.325 ft/ft
n = 0.022 CMP
At 0.325 fttft grade, 15" RCP will carry 30 cis flowing full and 12.5 cfs @ depth = 6.75".
Check Available Head for Pipe Flow
Checking for inlet, velocity head, and pipeline friction losses:
Total HL = H, + H + hT = (V`/2g)(ke + 1 + ((29n`L)/R..I)
where, ke = 0.6 for straight pipe inlet
A= 1.23 sf
V=Q/A= 10.16 ft/sec
R = A/WP = 123/(3.14)(1.25) = 0.49
L = 200 ft
Hj = 14.20 ft
Available HL = 597.7 - 538.8 = 58.9' >14.20' OK!
Use 200' of 15" CMP.

Attachment to Notice of Intent to Discharge Under NCG020000 rbGa.
By Little River Stone, LLC - Seagrove Quarry �0 GAad
September 29, 2006 7� y
Modified November 16; _2006.
(See attached Site Map and Water Flow Schematic for further explanation) V
6) Minerals mined:
The stone to be mined at this operation has been identified as a metamorphic
quartz schist; however, it is likely better characterized as a non -foliated metamorphic
quartzite or a metavolcanic tuff.
7) Discharge Points:
There will be two discharge points for this operation as follows:
1) Outfall 001 will be the intermittent discharge from an old quarry pit on the site to
a tributary to Little River immediately upstream of the river. This discharge will consist
of various combinations of (a) mine dewatering, (b) stormwater, and (c) process
wastewater. Since its primary and controlling component (from monitoring standpoint)
will be mine dewatering, it will be sampled and reported as such.
(a) All groundwater and stormwater runoff collected in the quarry pit will receive
primary treatment in a sump that will be maintained below the lowest pit floor level.
This mine dewatering will then be pumped as required to either the closed loop process
water system as makeup water or to the old quarry pit that will serve as secondary
treatment for this water.
(b) Stormwater runoff from the entrance road and shop area will be routed to a
sediment basin along the quarry entrance road for primary treatment. This sediment
basin will discharge to the old quarry pit which will serve as secondary treatment for this
stormwater.
(c) The process wastewater system is designed as a closed loop recycle system
that will only overflow during a rainfall event exceeding the 10-year, 24-hr. rainfall
event. The system will consist of two settling basins and a combination settling basin and
fresh water basin which will contain the plant fresh water pump that will supply the
aggregate washing operation. Influent to the system will consist of return water from the
aggregate washing operation, rainfall that falls directly into the system, and any makeup
water from the quarry pit dewatering operation as indicated above. Any overflow from
this system during rainfall events exceeding the 10-yr., 24-hr. storm will be routed to the
old quarry pit via a pipe outfaiI.
A pump will be installed in this old quarry pit and it will serve as the backup for
the fresh water makeup system during dry periods when there is little water collected in
the active quarry pit. It will also serve to fill the water truck that will distribute water
over the stockpile area, dirt haul roads, etc. in order to control fugitive dust emissions
from these sources.

2) SDO 001 will be the discharge from a sediment basin that will treat stormwater
runoff from the plant and product stockpile area and release it to a small tributary to Little
River.
11) BMP's for stormwater control:
See 7) above, which covers the installation of permanent sediment basins for
treatment of stormwater from the plant entrance road, shop area, and plant and product
stockpile area, as well as stormwater generated within the quarry pit. The clearing of
areas ahead of quarry development will be minimized in order to minimize the amount of
land exposed to erosive conditions. These limited areas of disturbance will drain into the
quarry pit or through erosion and sediment control devices such as brush barriers, silt
fencing, sediment traps, etc. onto undisturbed portions of the site.
15) Process wastewater treatment system:
a) Process wastewater will be treated by primary and secondary sedimentation in a
series of settling basins. Two basins will provide primary sedimentation under normal
conditions. Wash water outfall piping from the processing plant will be designed so that
either of the two basins will operate while the other is being cleaned out. Overflow from
the two primary basins will be routed via pipes to the secondary settling basin which will
also serve as the processing plant fresh water basin. A pump in this basin will return
water to the wash plant for reuse., Makeup water as needed to overcome system losses to
evaporation and into the finished products will be provided from the mine dewatering
pump as indicated above.
The total active volume in the settling basin system is 1,032,700 gallons."At a
pumping rate of 800 gpm (1.78 cfs) to the wash plant, under normal operating conditions
with both primary basins in service (400 gpm in each primary basin and 800 gpm in
secondary/fresh water basin), the retention time in the basin system will be 36.3 hours as
shown in the attached design notes.
The surface area at normal water level in each basin and the surface area to basin
outflow ratio will be as follows under normal operating conditions: / AlL ro
L
Basin surface area Surface area to outflow ratio
Primary "A' 7715 sf = 0.177 acs 8668 sf/cfs y 3 3 `{
Primary `B" 7134 sf = 0.164 acs 8016 sf/cfs nv 16 A v
Secondary/F.W. 6706 sf = 0.154 acs 3767 sf/cfs
The Di5 size of material entering the basin system from the washing operation = +/-
0.045 mm (325 mesh). The settling velocity of this particle VI5 = +/- 0.003 fps. For
each basin, the ratio, (Qp,,) / (V15)(Surfacee Area), and the resulting trapping efficiency are
as follows: t h aGr e-5
p Primary "A"
Primary `B"
Du.{ q_4&2'V7u� 7 Secondary/F.W

Ratio Trapping Efficiency
1676 +94%
1809 +94%
3853 +92%
—J 3853 �
0 -1 S`E

Under normal operating conditions, the overall system trapping efficiency for 1315
particles = +1-94%. This will be somewhat diminished when one of the primary basins
being cleaned but will stilt be in the 92%_range.
(Reference "Engineering Aids and Design Guidelinesfor Control of Sediment " by John C. Hayes
and Billy J. Barfield)
These retention time and surface area to outflow parameters indicate that, with
continuing removal of the accumulated solids as required, the basin system will remove
solids with adequate efficiency to allow the water to be used for recycling.
b) In order to insure that a high quality of return water is available at all times and
that, should the process wastewater basins overflow as the result of a storm event, the
overflow will be as clean as possible, the permittee proposes to use a polymeric
flocculent to flocculate additional suspended solids on an as needed basis. The polymer
used in the non -discharge, closed loop recycle process wastewater settling basin system
will be:
(1) Nalco Cat -Floc 9856 Plus;
(2) RMC (Rochester Midland Corp.) MIDFLOC 1316E, MIDFLOC
1320L, and MIDFLOC 1321L; or
(3) Kemira Chemicals INDUSET 246
Likewise, to insure a high quality effluent from Outfall 001, the permittee
proposes to add one of the following polymeric flocculents to the mine dewatering
entering the old quarry pit on an as needed basis.
(4) Nalco En -Act 7883
(5) RMC (Rochester Midland Corp.) MIDFLOC 1309L
(6) Kemira Chemicals INDUSET 246
All of these products have a proven track record of low toxicity due to their
chemical makeup, as well as their resultant behavior and breakdown in the ponds. All
are used extensively in the mining industry. The permittee will determine the product
which yields the best combination of pricing and performance based on bench tests at
startup of the quarry and subsequently provide DENR with the proposed dosage rates and
daily quantity of use.
c) Design calculations are attached to show that the basin system will overflow only
during rainfall events exceeding the 10-yr., 24-hr. rainfall event. Indeed, the calculations
show that the basin system will not overflow even during the 100-yr, storm event. An
emergency overflow pipe will be installed to allow stormwater accumulation from an
event exceeding the 100-yr, storm event to be safely channeled to the old quarry pit. Any
excess accumulation of water in this old pit will overflow through Outfall 001.

k) Special Notes: Proposing use of flocculants as needed for both recycle system and
dcwatering. See Process Wastewater Treatment Calculations Review for other notes.
Site Plans and Process Wastewater Treatment Calculations Review.
• Proposing use of flocculants for recycle system and dewater pit on an as -needed basis.
Proposed flocculants are not currently on FTC's approved list-- w4ill�need-to advise applicant
to Llse-f'pprv'ed subst' nces�for dewatcriiig system that_ "ifl'dischart! . (of recycle system is
non -discharging at 25-vr rain event, it doesn't have the same restriction).
• Mine dcwatering water contained in old quarry pit will also be used at times to spray down
stockpile area, haul roads, etc. This means wastewater will potentially commingle with
stormwater discharged through SDO 1.

NCG020695 November' 13, 2006

• Holding time calculations for wastewater recycle system assume all three basins operating
simultaneously. Narrative states that one primary basin is designed to operate while the
other is cleaned out...calcs don't reflect this? See phone logs. If both primary basins in
service, only 400 gprn to each (holding time will change); if only one, won't have
benefit of holding time of other.(except in rain event)_. Engineer will revise; advised
that he include "worst case" scenario of one primary: basin out of service.
• Total volume calculated for recycle basins includes 2' freeboard in the primary basins and 3'
freeboard in the secondary basin. However, the sum of those volumes (1,032,700 gal) does
not agree with the volume used to used to estimate the trapping efficiency for the particles
moving through it (1,087,000 gal)...? Seephnne logs. Engineer will revise.
• If the recycle system is entirely closed -loop, why are there hyd.rograph calculations for a 1.8
acre drainage area into the system? See phone logs. Comprised of basins themselves and
area immediately surrounding the basins (a perimeter about 50' outside) —includes
area where material drop out will drip and drain back to system (from cleaning). Site
plan area appears consistent. Okay as long as this area contained adequately and
basins can hold design storm + adequate freeboard.
Modified Calculations (Submitted 11120) Review:
✓ Corrected total active volume (corresponds to normal water level in basins with 2' freeboard)
✓ Outlined particle trapping efficiency for all three basins based on eroded particle size of-
0.045 mm. Checked basin ratios, and trapping efficiencies look reasonable. For "worst
case," Primary Basin A will be out of service, and its ratio would be 3618... should yield an
efficiency slightly lower than the secondary basin (but close to 92%). " Recycle system settling
should be adequate.
✓ Revised holding times for wastewater settling basins —included scenarios of `t1' out of
service as well as basins half full of solids.
✓ To check retention for 10-yr event, estimated runoff from 5.3" of rainfall on all 1.8 acres
(basins + isolated area draining to them), assuming 100% impervious. Plenty of room in
freeboard (if all filled to normal water level, 2' below overflow) to contain even if entire area
impervious (conservative way to check hydrograph calcs). Noy freeboard volume estimate
also didn't account for any slope, so mote capacity available.
✓ Checked retention for 100-yr event, and okay if 1.8 acres considered 85% impervious
(probably not far off given CN assumptions). Hydrograph may be more accurate in this
case. For 25-yr event (-6.3"), still plenty of freeboard capacity to hold all runoff, so.
overflow should not an issue anyway. [Note —this is different from Ready -Mix recycle
systems where we look for capacity to contain the•25-year event plus one foot of .
freeboard. See NCG02.]
Phone logs
11 /16/06: Requested additional information from Steve Howiler (843.537.4784). Will revise
calculations and narrative, and send by the end of the week. Items discussed:
✓ Drainage area to recycle system: basins themselves + area immediately surrounding it (where
material dropout will drain back into the system an) -way).'..

✓ Most of the time, both primary basins and secondary basin wvill be operating. When one
cleaned, only takes a few days. [Recommended recalculating holding times with assumption only
one primary basin in service.]
✓ Volume used in trapping efficiency calculations discrepant with wastewater design talcs —should
be corrected.
✓ Will correct above items and resubmit narrative and talcs.
12/1 /06: Mike Lavyer (FRO) called after a site visit here. Some construction has begun but no
mining vet. Possible that wetlands could be affected (they are in the vicinity), even though owner
said he didn't think so. FRO agrees O&M Plan requirement a good idea to have them investigate
that possibility further. Everything else indicates it will be a good site. Owner is keeping the
consulting engineer who is familiar with this permit to handle sampling requirements, etc. Mike will
send an e--mail next week with FRO's recommendation to issue the COC.
12/6/06: Phoned Steve Flowiler to convey approval of COC, 0&111 Plan requirement, and Pr1M

Hi Bethany! As you know, I conducted a site visit to the proposed Seagrove Quarry in
Montgomery County last week. After speaking to the engineer, Mr. Howiler, I feel
pretty confident with the stormwater and process water control measures they have
proposed. Also, since Mr. Howiler is very familiar with the general permit, has
worked with other mining companies and will be retained to perform proper monitoring
and compliance, I recommend proceeding with issuance of their certificate of coverage
under the NCG020000 general permit. As I mentioned to you last week, Mr. Howiler did

If you need any further comments, please contact me.
On another topic, can DWQ rescind permit coverage for an industry that we know is no
longer in operation. Specifically, we have discovered that one of our permitted
facilities (Woodard Inc-NCG180216) has been abandoned. It appears that the facility
has been shut down for a while and we would probably be unable to contact anyone with
the company to request that they submit a rescission request letter. Can the Division
go ahead and rescind without a request letter from the permittee?
Thanks,

Hi Mike,
I'd requested additional info. on the wastewater recycling system talcs for this
quarry, so I'm sending you a hard copy of what we received for the FRO files. I
reviewed those last week, and they look okay, so I think we can consider their
application complete. Not sure if you've had an opportunity to visit the site yet or
not, but when you do, let me know if wetlands will potentially be impacted. If so,
this site will require an 0&M Plan once we issue the permit and before they start
operation.
Hope you had a nice Thanksgiving!

Mike,
We've received an NOI from Little River Stone, LLC for an NCG02 mining
stormwater/wastewater permit for their Seagrove Quarry. They've already
received their Mining Permit (f 62-41) from DLR on June 15, 2006f.''
I'm only attaching the map to this e-mail because I'm sending a hard copy of the
package to you (includes site plan, NOI, treatment system talcs, etc.) They are
proposing a closed -loop recycle system for their process wastewater, but will
discharge mine dewatering water and stormwater. (Technically an ATC won't be
required for this one since it's a crushed stone quarry and their recycle system
is closed -loop, but I do intend to'review their process WW treatment system
talcs before approving the COC.) They're proposing to use DAMS for flocculation
as needed, so I plan to explain they'll have to refer to the list of approved
products in NC.
The operation will discharge to a couple of trios to the Little River, in a
segment designated as C waters in the Yadkin Basin. From the site plan, it
looks like there are wetlands in the vicinity, -which is another reason I wanted
to send a copy of the package for you to review.
Does the Fayetteville Regional Office have any concerns about issuing this
facility a COC for this general permit, and is there the potential to impact
wetlands nearby? We'll require an 0&M plan prior to operation if that's the
case.(which I'll put in the letter). _ Normally if we don'.t receive any
objections we issue the COC in 30 days, but I usually hold off on mining
permits, especially if wetlands may be affected_ Just let me know when you've
had a chance to look through the application.
Thanks!

trapping device. They should be used as velocity checks only as a short-term
temporary solution.
Specific conditions for use include new diversion ditches that will not or cannot
be stabilized for several days, and temporary diversion channels that are eroding
due to high flow rates or steep slopes.
Design Criteria
The bags shall be filled with KTC No. 57 stone. The dam shall span the banks of
the ditch or swale. The height of the dam on the stream centerline should equal
the height of flow for the 2-year 24-hour storm event. Bags should be placed on
the bank to a height at least 6 inches higher than the center of the dam.
Space Stone Bag Check Dams such that the crest of the downstream dam is at the
same elevation of the toe of the dam located immediately upstream. Show the
designed spacing on the EPSC plans.
12.8 ENGINEERING AIDS AND DESIGN GUIDELINES FOR SEDIMENT
CONTROLS
This section presents design aids that were developed for use in designing four types of
sediment control structures; temporary sediment basins (Section 12.6.2), temporary
sediment traps (Section 12.6.4), silt fences (Section 12.6.5), and rock ditch checks
(Section 12.6.6) for Jefferson County, Kentucky. These design aids will each be briefly
described and then examples will be used to demonstrate their use in realistic problems.
Settling velocity will be discussed to begin.
12.8.1 Characteristic Settling Velocity and Eroded Particle Size
A common feature of each of the design aids is that a characteristic settling
velocity for the eroded soil must be obtained. For Jefferson County conditions,
this velocity corresponds to an eroded size such that 15% of the sediment has
particles smaller than the size specified. The procedure for empirically estimating
eroded size distributions is best described by Hayes et.al (1996). Characteristic
settling velocity corresponds to an eroded particle diameter that is referred to as
1315. This diameter represents the point on the eroded particle size distribution
curve where 15% of the particles (by weight) are equal to or smaller than this size.
Estimated eroded size distributions for Jefferson County soils using an adaptation
of the method described by Foster et al. (1985) were developed. The procedure
uses the primary particle size information reported by SCS as part of county soil
surveys. This procedure may be used with USDA Soil Survey Data or site specific
soil boring data. Other procedures are given by Haan et.al. (1994) for physically
based estimating procedures. If D15 is less than 0.01 mm, then settling velocity
based upon a simplified form of Stokes Law is:
Effective: January 1, 2001 12.38

V5= 2.81d2 (1)
Where: Vs is settling velocity in ft/sec and d is diameter in mm. If D15 is greater
than or equal to 0.01 mm, then settling velocity should be found using
Iog1DV5 0.34246 (loglod)' + 0.98912 (loglod) - 0.33801 (2)
Where: V5j is settling velocity in ft/sec and d is particle diameter in mm (Wilson
et al., 1982). The characteristic settling velocity can be obtained using Figure 12.1
and the eroded particle size (Di5) for soils found in Jefferson County, which is
provided in Supplemental Section D.
It is important to remember that the eroded size distribution is the most critical
parameter in sizing sediment controls. The eroded size distributions vary greatly
from primary particle size distributions that are. often determined as a result of soil
strength investigations for construction purposes. Primary particle sizes will yield
erroneous results and should not be used.;The user should note that D15 is often .
smaller for coarse textured (more sandy soils) because of the reduced clay content
and the lack of aggregation.

Effective: January 1, 2001 12-39

12.8.2 Sediment Basin Design Aids
Figure 12.2 plots the basin ratio (qpo/AV,S) versus percentage of trapping
efficiency. For basins; the ratio is defined by:
Basin Ratio =gpdAVt; (3)
Where: q�, = peak outflow rate from_the_basin_(cfs), A =surface area of the
pond at riser crest(acres),Vi5 = (from Figure 12.1) characteristic
settling velocity (fps), of the characteristic Dt5 eroded particle
(mm).
Figure 12.2 is for soils classed as either coarse (sandy loam), medium (silt loam),
or fine (clay loam) as shown in Table 12-8. The ratio should be less than or equal
to the curve value at any given trapping efficiency. For example, at 80% trapping
efficiency, the basin ratio equals 2.OE5 as shown in Figure 12.2. If the basin ratio
gpdAV,s intersects the curve at a point having a trapping efficiency less than the
desired value, the design is inadequate and must be revised.
Basin Ratios above the design curves are not recommended for any
application of the design aids. Constraints for use of Figure 12.2 are: y
✓ • Watershed area less than or equal to 30 acres
✓• o '
Overland slope less than or equal to 20 /o
✓• Outlet diameter less than or equal to 6 feet

Effective: January 1, 2001 12-40

12.8.3 Rock Ditch Check Design Aids
Design aids for rock ditch checks were developed similarly to those for ponds.
Again, the D15 eroded particle size is used for the calculation of the characteristic
settling velocity. The ratio for ditch checks is defined by:
Ditch Check Ratio = Sq(1 e)/aV15 (4)
Where: S = channel slope (%),
q = flow through the check (cfs/ft),
V15 = (from Figure 12.1) characteristic settling velocity (fps),
of the characteristic D15 eroded particle (mm).

D50 = rock ditch check average stone diameter in meters.
dl = average flow length through the rock ditch check in meters.
If the check overtops, the trapping efficiency is assumed to be zero. Figures 12.3a,
12.3b, and 12.3c can be used for estimating trapping efficiency of rock ditch
checks. Table 12-8 provides guidance to determine which plot is appropriate.
Ditch Check Ratios above the design curves are not recommended for any
application of the design aids. Constraints for the use of Figures 12.3a, 12.3b,

b) Determine runoff depth
From Figure 8.03j, for Montgomery County, the rainfall amount
for the 10-year, 24-hr. storm at site, P = 5.3 inches
Ultimate Soil Storage Capacity = S = (10001CN) - 10 = 1.07 inches
Runoff depth, Q, = (P-0.2S)2/(P+0.8S) = 4.20 inches
c) Determine peak rate of runoff for the design storm by adjusting for
watershed shape
Using the equation L = 209*a^°.6 ,where (L) is the hydraulic length and (a) is the drainage area
the equivalent drainage area is therefore, a = 0.9 acres
From figure 8.03p, 2% slope, CN = 90; peak rate of runoff = 1.8 cfsl<nch
Q, = Peak Rate Runoff ' Or = 7.6 cfs
Q2 = Q, * Actual Area/Equiv Area = 14.6 cfs
d) Adjust peak discharge rate 02 for percent Impervious area (none, therefore factor

From figure 8.03r, for CN = 90 and % length modified = 0
hydraulic length adjustment factor 1.00
therefore, Q3 = Q2 * adj factor = 14.6 afs
e) Adjust peak discharge rate Q3for average watershed slope

b = ln(S2/S,)An(Z2/Z,) = In(48222123167) / In(211) = 1.058
KS = 52 / (Z2)b = 482221(2rl.058 = 23167
Check constants using Z = (S/KS)'m
At depth =1', 1' = (23167/23167)'".°s = 1.0 ft
Therefore, since the result is within 0. T, we can consider the constants valid.

We see that maximum stage will be 1.18' (elevation = 95.68) above normal water level and 0.82' below
emergency spillway elevation (elevation = 96.50) for the 10-yr, 24-hr storm inflow to the basin. Bank
full elevation is 1.37 above this maximum stage. For a dug pond, this is okay; however actual high
elevation around pond is 1' higher, so freeboard will actually be 2.32'.
C) Check 24-hr. storm event inflow to basin system and size outfall dive
1) - Calculate Peak Flow, 010, inflow to basins for the contributing
drainage area using SCS TR-55, and flood routing
b) From Figure 8.03j, for Montgomery County, the rainfall
amount for the 100-year, 24-hr. storm at site, P = 7.7 inches
Ultimate Soil Storage Capacity = S = (10001CN) -10 = 1.07 inches
Runoff depth, Q, = (P-0.2S)21(P+0.8S) = 6.55 inches
c) Determine peak rate of runoff fsor the design storm by adjusting for
watershed shape
Using the equation L = 209" a,0.6 ,where (L) is the hydraulic length and (a) is the drainage area
the equivalent drainage area is therefore, a = 0.9 acres
From figure 8.03p, 2% slope, CN = 90; peak rate of runoff = 1.8 cfsfinch
Q, = Peak Rate Runoff " Qr = 11.8 cfs
02 = Q1 * Actual Area/Equiv Area = 22.8 cfs
d) Adjust peak discharge rate (h for percent Impervious area (none, therefore factor
=1) and percent hydraulic length modified:
From figure 8.03r, for CN = 0 and % length modified = 0
hydraulic length adjustment factor 1.00
therefore, Q3 = QZ • adj factor = 22.8 cfs
e) Adjust peak discharge rate 03 for average watershed slope
By interpolation from Table 8.03d, for avg_ slope = 2.0 and drainage area =
adjustment factor - 1.06
Q4 = Q3* adj. Factor = 24.2 cfs
f) Adjust peak discharge % for surface ponding
From Table 8.03e, for Q40and ponding ratio = 3.7 at design point
Adjustment factor = 0.77
Adjustment factor
Average factor = 0.77
Qp looA = Q4 *adj. Factor = 18.6 cis

Applying step function, calculate inlet flow to basin for various times using:
for time between zero and 1.25 Tp: Q = Qp/ 2 *((1-cos(Td / Tp))

We see that maximum stage will be 1.8' above normal water elevation (elev = 596.3) and OX below
emergency overflow (596.5), for the 100 yr storm inflow to the basin. Bank full elevation is OX
above this maximum stage. For a dug pond, this is okay; however actual high elevation around pond
is V higher, so freeboard will actually be 1.7'.
2) - Size emergency overflow pipe
Assume maximum outflow at >100-yr. storm = 12.50 cfs 2f3 of 100-yr. storm inflow
(see above) This is VERY conservative
5 = 596.5-588/150' = 0.0567 Wit
n = 0.013 RCP or smooth -bore CPP
At 0.0567 fi/ft grade, 15' RCP will carry 15.5 cfs flowing full and 12.5 cfs depth = 10.5'.
Check Available Head for Pipe Flow
Checking for inlet, velocity head, and pipeline friction losses:
Total Hr = Hg + H„ + hE _ (V/2g)(ka + 1 + ((29n`L)/R'-"))
where, ke = 0.6 for straight pipe inlet
A= 1.23 sf
V=Q/A= 10.16 ftlsec
R = ANVP = 1.23/(3.14)(1.25) = 0.49
L = 150 ft
Ht = 5.61 ft
Available HL = 597.7 - 58&8 = 8.9' > 5.61' OKf
Use 150' of 15" RCP.

Attachment to Notice of Intent to Discharge Under NCG020000
By Little River Stone, LLC - Seagrove Quarry
September 29, 2006
(See attached Site Map and Water Flow Schematic for further explanation)
6) Minerals mined:
The stone to be mined at this operation has been identified as a metamorphic
quartz schist; however, it is likely better characterized as a non -foliated metamorphic
quartzite or a metavolcanic tuff.
7) Discharge Points:
There will be two discharge points for this operation as follows:
1) Outfall 001 will be the intermittent discharge from an old quarry pit on the site to
a tributary to Little River immediately upstream of the river. This discharge will consist
of various combinations of (a) mine dewatering, (b) stormwater, and (c) process
wastewater. Since its primary and controlling component (from monitoring standpoint)
will be mine dewatering, it will be sampled and reported as such.
(a) All groundwater and stormwater runoff collected in the quarry pit will receive
primary treatment in a sump that will be maintained below the lowest pit floor level.
This mine dewatering will then be pumped as required to either the closed loop process
water system as makeup water or to the old quarry pit that will serve as secondary
treatment for this water.
(b) Stormwater runoff from the entrance road and shop area will be routed to a
sediment basin along the quarry entrance road for primary treatment. This sediment
basin will discharge to the old quarry pit which will serve as secondary treatment for this
stormwater.
(c) The process wastewater system is designed as a closed loop recycle system
that will only overflow during a rainfall event exceeding the 10-year, 24-hr_ rainfall
event. The system will consist of two settling basins and a combination settling basin and
fresh water basin which will contain the plant fresh water pump that will supply the
aggregate washing operation. Influent to the system will consist of return water from the
aggregate washing operation, rainfall that falls directly into the system, and any makeup
water from the quarry pit dewatering operation as indicated above. Any overflow from
this system during rainfall events exceeding the 10-yr., 24-hr. storm will be routed to the
old quarry pit via a pipe outfall.
A pump will be installed in this old quarry pit and it will serve as the backup for
the fresh water makeup system during dry periods when there is little water collected in
the active quarry pit. It will also serve to fill the water truck that will distribute water
over the stockpile area, dirt haul roads, etc. in order to control fugitive dust emissions
from these sources.

2) SDO 001 will be the discharge from a sediment basin that will treat stormwater
runoff from the plant and product stockpile area and release it to a small tributary to Little
River.
11) BMP's for stormwater control:
See 7) above, which covers the installation of permanent sediment basins for
treatment of stormwater from the plant entrance road, shop area, and plant and product
stockpile area, as well as stormwater generated within the quarry pit. The clearing of
areas ahead of quarry development will be minimized in order to minimize the amount of
land exposed to erosive conditions. These limited areas of disturbance will drain into the
quarry pit or through erosion and sediment control devices such as brush barriers, silt
fencing, sediment traps, etc. onto undisturbed portions of the site.
15) Process wastewater treatment system:
a) Process wastewater will be treated by primary and secondary sedimentation in a
series of settling basins. Two basins will provide primary sedimentation. Wash water
outfall piping from the processing plant will be designed so that either of the two basins
will operate while the other is being cleaned out. Overflow from the two primary basins
will be routed via pipes to the secondary settling basin which will also serve as the
processing plant fresh water basin. A pump in this basin will return water to the wash
plant for reuse. Makeup water as needed to overcome system losses to evaporation and
into the finished products will be provided from the mine dewatering pump as indicated
above.
The total active volume in the settling basin system is 1,087,000 gallons. At a
pumping rate of 800 gpm (1.78 cfs) to the wash plant, the retention time in the basin
system will be 1358 minutes, or 22.6 hours.
The surface area at normal water level in the basins will be approximately 21,500
sf . Surface area to basin outflow ratio equals:
21,500 sIV1.78 cfs = 12,078 sflcfs
The D15 size of material entering the basin system from the washing operation = +/-
0.045 mm (325 mesh). The settling velocity of this particle V15 = +/- 0.003 fps.
(Qp.) / (V15)(Surface Area) = (1.78 cfs) / (0.003 fps)(0.493 acs) = 1203
Trapping efficiency for D15 particles = +/-94%
(Reference "Engineering Aids and Design Guidelines for Control of Sediment " by John C. Hayes
and Billy J. Barfield)
These retention time and surface area to outflow parameters indicate that, with
continuing removal of the accumulated solids as required, the basin system will remove
solids with adequate efficiency to allow the water to be used for recycling.

b) In order to insure that a high quality of return water is available at all times and
that, should the process wastewater basins overflow as the result of a storm event, the
overflow will be as clean as possible, the permittee proposes to use a polymeric
flocculent to flocculate additional suspended solids on an as needed basis. The polymer
used in the non -discharge, closed loop recycle process wastewater settling basin system
will be:
(1) Nalco Cat -Floc 9856 Plus;
(2) RMC (Rochester Midland Corp.) MIDFLOC 1316E, NIIDFL.00
1320L, and NODFLOC 1321L; or
(3) Kemira Chemicals INDUSET 246
Likewise, to insure a high quality effluent from Outfall 001, the permittee
proposes to add one of the following polymeric flocculents to the mine dewatering
entering the old quarry pit on an as needed basis.
(4) Nalco En -Act 7883
(5) RMC (Rochester Midland Corp.) N DFLOC 1309L
(6) Kernira Chemicals INDUSET 246
All of these products have a proven track record of low toxicity due to their
chemical makeup, as well as their resultant behavior and breakdown in the ponds. All
are used extensively in the mining industry. The permittee will determine the product
which yields the best combination of pricing and performance based on bench tests at
startup of the quarry and subsequently provide DENR with the proposed dosage rates and
daily quantity of use.
c) Design calculations are attached to show that the basin system will overflow only
during rainfall events exceeding the 10-yr., 24-hr. rainfall event. Indeed, the calculations
show that the basin system will not overflow even during the 100-yr. storm event. An
emergency overflow pipe will be installed to allow stormwater accumulation from an
event exceeding the 100-yr_ storm event to be safely channeled to the old quarry pit. Any
excess accumulation of water in this old pit will overflow through Outfall 001.
