The subject permittee which operates a granite quarry submitted their
renewal application on 12/28/98 with a $200 permit renewal fee. I
discussed the revised Mining General Permit (NCG02000) with them, and
they would now like to switch their application from individual to
General Permit coverage. Their main concern was whether the General
Permit allows for turbidity compliance to be measured through instream
sampling, which it does. The Winston Salem Region concurs with the
requested switch. I will foward the NPDES file and application to
Bradley. I've indicated on IMS that NC0006483 has requested the change
to GP coverage. General Permits Unit- Please alert Compliance (Robert
Farmer) and NPDES (Charles Weaver) as to when the current individual
permit will be superceded by the General Permit requirements. Thanks.

Subject: NPDES Permit Renewal, NC0006483- NC Granite Corp.
Tony- could you take a look at this renewal application for a granite quarry and let me know if
it could be covered by General Permit (GP), and still meet the permittee's concerns. Originally
this was an individual permit (NC0006483), which was shifted to GP coverage (NCG020163) in
1993. In 1995 the permittee requested a switch back to an individual permit, because the
turbidity limit in the GP had to be met in the effluent, whereas the individual permit allowed
upstream/downstream considerations. The Division agreed to convert back to an individual
permit in 1995, with the addition of stormwater BMPs. If this renewal can't be covered by GP,
what stormwater info do you need to be included in the individual permit? I've tabbed the
pages in the current permit that deal with stormwater issues, but I'm not sure how much of
this is still relevant. Thanks.
Some background info- the facility is a 97 acre granite quarry, where granite is cut and
polished. Process wastewater (0.3 MGD) is generated by cooling of cutting saws and polishing
machines. The wastewater is discharged to two 1/4-acre settling ponds in series, prior to
stream discharge. AA

PART
SECTION A: FINAL LIMITATIONS AND CONTROLS FOR STORMWATER AND
. WASTEWATER DISCHARGES
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge stormwater, overflow from facilities that recycle process
wastewater, and/or effluent from mine dewatering. Such discharges shall be controlled, limited,
and monitored as specified below:
1. The Permittee shall implement Best Management Practices (BMPs) to ensure that contaminants
do not enter surface waters via stormwater that comes in contact with any unstabilized overburden,
raw materials, intermediate products, finished products, byproducts or waste products located on
the site of the sources covered by this permit. A BMP plan shall eveloped in accordance with
Part I, Section C of this permit for each facility covered by s ermit.
2. The Permittee shall implement management practices and the Erosion and Sedimentation
Control Plan that are included in the mining permit which have been approved by th iv' ' of
Land Resources. The approved permit is considered a requirement or condition oft ' n `al
permit. Deviation from the approved permit, or, r ved amendment to the permit, sh stitute
a violation of the terms and conditions of t ralppermit, A signed copy of the issued mining
permit including the approved Erosion and e 'merimon Control Plan and the Reclamation Plan
shall be maintained on the site at all times. Once an area is released by the Division of Land
Resources in acc6rdance with NCGS Chapter 74, Article 7, it shall no longer be subject to this
permit.
3. Equipment utilized during the mining activity on a site must be operated and maintained in such
a manner as to prevent the potential or actual pollution of the surface or ground waters of the state.
Fuels, lubricants, coolants, and hydraulic fluids, or any other petroleum products, shall not be
discharged on to the ground or into surface waters. Spent fluids shall be disposed of in a manner
so as not to enter the surface or ground waters of the state and in accordance with applicable state
and federal disposal regulations. Any spilled fluids shall be cleaned up to the maximum extent
practicable and disposed of in a manner so as not to allow their entry into the surface or ground
waters of the state.
4. Above ground bulk storage of petroleum products and storage of Section 313 Water Priority
Chemicals shall have secondary containment devices within the first 12 months of permit coverage
for existing discharges and prior to beginning operations for new discharges to prevent leaks and
spills from contaminating stormwater runoff.

Part I
Section B: MINIMUM MONITORING AND REPORTING REQUIREMENTS (unless otherwise
approved in writing by the Division of Environmental Management)
1. All erosion and sedimentation control facilities shall be inspected by or under the direction of
the permittee at least once every seven calendar days and within 24 hours after any storm event
that results in a discharge of runoff of stormwater from the site.
2. Stormwater runoff discharges shall be inspected by visual observation for color, foam, outfall
staining, visible sheens and dry weather flows at the above frequency to evaluate the effectiveness
of the stormwater control facilities or practices. If any visible off -site sedimentation is leaving the
property, corrective action shall be taken to reduce the discharge of sediments.
3. The permittee shall keep a record of inspections. Visible sedimentation found off the site shall
be recorded with a brief explanation as to the measures taken to prevent future releases as well as
any measures taken to clean up the sediment that has left the site. This record shall be made
available to DEM or authorized agent upon request.
4. A log of the sampling data and of activities taken to implement BMPs associated with the
vehicle maintenance activities shall be maintained and incorporated into the BMP Plan.
5. A log of the sampling data and of activities taken to implement the BMP Plan shall be kept on
site for the duration of the permit tirm and made available to the Director immediately upon
request.
5. For purposes of the stormwater sampling required in this permit, all samples shall be collected
from the discharge resulting from a representative storm event (See Part III, Stormwater
Definitions, 5). Samples shall be collected at intervals not less than one year apart. If the
stormwater runoff is controlled by a detention pond, the following sampling requirements apply:
(a) If the detention pond detains for 24 hours the runoff generated by one inch of rainfall, a
grab sample of the discharge from the pond shall be collected within the first 30 minutes of
discharge.
(b) If the detention pond discharges only in response to a storm event exceeding a ten year
design storm (See Part Ill, Stormwater Definitions, 12), visual observations of the
discharge for color, foam, outfall staining, visible sheens and dry weather flows, are
required but analytical sampling shall not be required.
(c) If the detention pond discharges only in response to a storm event exceeding a 25-year,
24-hour storm (See Part 111, Stormwater Definitions, 15), the pond shall be considered a
non -discharging stormwater control system and not subject to NPDES requirements,
unless the discharge causes a violation of water quality standards.
7. The analytical results of samples analyzed in accordance with the terms of this permit shall be
submitted on forms provided by the Director no later than January 31 for the previous year in
which sampling was required to be performed.

Section C: Schedule of Compliance
1. The permittee shall comply with Final Limitations and Controls specified for stormwater
discharges in accordance with the following schedule:
For the vehicle maintenance activities:
a. Develop and implement BMP's and stormwater controls, as appropriate within the first
12 months of permit coverage, at existing operations.

5. Mass/Dav Nleasurement<s
The "monthly average discharge" is defined as the total mass of all daily discharges
sampled and/or measured during a calendar month on which daily discharges are sampled
and measured, divided by the number of daily discharges sampled and/or measured during
such month. It is therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by the number of days
the tests were reported. The limitation is identified as "Monthly Average" in Pan I of the
permit.
b. The ",A-eekl,,- average discharge" is defined as the total mass of all daily discharges sampled
and/or measured durinc, the calendar week (Sunday - Saturday) on which daily discharges
are sampled and measured, divided by the number of daily discharges sampled and/or
measured during such week. It is, therefore, an arithmetic mean found by adding the
weights of pollutants found each day of the week and then dividing this sum by the
number of days the tests were reported. This limitation is identified as "Weekly Average"
in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during
a calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found
each day of the year and then dividing this sum by the number of days the tests were
reported. This limitation is defined as "Annual Average" in Part I of the permit.

Part II
Page 2 of 14
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of
the concentrations of all daily discharges sampled and/or measured during a calendar month
on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in
Pan I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of
the daily concentration values). The daily concentration value is equal to the concentration
of a composite sample or in the case of grab samples is the arithmetic mean (weighted by
flow value) of all the samples collected during that calendar day. The average weekly count
for fecal coliform bacteria is the geometric mean of the counts for samples collected during
a calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar dav, If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration It is identified as
"Daily Maximum" under "Other Limits" in Part I of the permit.
d . The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all dail% discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily
discharges sampled and/or measured during such year (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day . The average yearly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar )Fear. This limitation is identified as "Annual Average" under "Other Limits" in
Pan I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount
of dissolved oxygen required to be available in the effluent prior to discharge averaged
over a calendar day. If only one dissolved oxygen sample is taken over a calendar day, the
sample is considered to be the "daily average concentration" for the discharge. It is
identified as "daily average" in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through
March, April through June. July through September, and October through December.

Part II
Page 3 of 14
7. Other Measurements
Flow. (NIGD): The flow limit expressed in this permit is the 24 hours average flow,
averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded
during the calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling,
when both the sample and flow will be representative of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which
occurs continually without interruption throughout the operating hours of the facility. Flow
shall be monitored continually except for the infrequent times when there may be no flow
or for infrequent maintenance activities on the flow device.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(I ) a series of grab samples collected at equal time intervals over a 24 hour period of
discharge and combined proportional to the rate of flow measured at the time of
individual sample collection, or
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the
sampling point. Flow measurement between sample intervals shall be determined by
use of a flow recorder and totalizer, and the present gallon interval between sample
collection fixed at no greater than 1/24 of the expected total daily flow at the treatment
SN'stem, or
(3) a simple, continuous sample collected over a 24 hour period proportional to the rate of
flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time
of greater than 24 hours. In such cases, effluent grab samples may be collected at time
intervals evenly spaced over the 24 hour period which are equal in number of hours to the
detention time of the system in number of days. However, in no case may the time interval
between effluent grab samples be greater than six (6) hours nor the number of samples less
than four (4) during a 24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be
representative of the discharge or the receiving waters.
9. Calculation of Me s
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the
individual values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of
the individual values where N is equal to the number of individual values. The geometric
mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual
values. For purposes of calculating the geometric mean, values of zero (0) shall be
considered to be one (1).

Part 1I
Page 4 of 14
Weighted by Flow Value: Weighted by flow value means the summation of each
concentration times its respective flow divided by the summation of the respective flows.
10. Calendar Dav
A calendar day is defined as the period from midnight of one day until midnight of the next
day. However, for purposes of this permit, any consecutive 24-hour period that reasonably
represents the calendar day may be used for sampling.
11. Hazardous Substance
A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to
Section 311 of the Clean Water Act.
12. Toxic Pollutant
A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Granite is cut and polished at this facility. The discharge consists of wastewater used to cool
cutting saws and polishing machines. Wastewater goes to the two settling ponds where a polymer
is added to aid the settling. The discharge then flows to the Ararat River.
A spring runs across the granite acreage and eventually flows to the Ararat. The region discovered
that 2 discharges of cooling water from the diamond cutting saws also flowed to the spring. The
region has instructed NC Granite to route these discharges to the settling basins. The spring water
itself cannot be routed to the settling basins because they do not have the capacity to accept that
kind of flow during a storm event. When the storm water permitting process is promulgated, the
runoff to the spring flow will have to be scrutinized.
No toxics are expected to be present, so toxicity testing is not recommended.

7. Size (land available for expansion and upgrading):
Total acreage of the property is 268 acres; of this amount
97 acres are exposed white granite. There is marginal room
for any expansion of the two settling ponds.
B. Topography (relationship to flood plain included):
Topography at the site is varied, from moderately sloped on
the western edge, to flat on the eastern edge, as the Ararat
River is approached. Run-off from the open-faced quarry
(97 acres of exposed impervious surface) flows from SE-� NW,

towards the settling ponds and the River. Upstream flood
control structures and C.O.E. channelization work to the
Ararat appear to have lessened the threat of flood.
9. Location of nearest dwelling: None within 1000.0' of the
settling ponds or discharge point.
10. Receiving stream or affected surface waters: Aarat River
a. Classification: "C"
b. River Basin and Subbasin No.: Yadkin 03--07-03
C. Describe receiving stream features and pertinent
downstream uses: The Aarat River is a major tributary
of the Yadkin River Basin. It is a rural watercourse
which originates in the Blue Ridge Mountains. Its uses
are consistent with its "C" classification. The upper

3. Description of industrial process (for industries only)
and applicable CFR Part and Subpart: This facility is a 97
acre open-faced granite quarry. Granite is removed in large
blocks, is cut, and is then polished. The stone is used for
monuments, building facing, and other decorative purposes.
4. Type of treatment (specify whether proposed or
existing):
Existing: The facility has, in a sense, two separate waste
streams. The primary waste stream contains the bulk of the
water generated from the cutting and polishing operations
and is treated by two 1/4 acre settling ponds operated in
series. A polymer is added to promote precipitating of
inorganic material.
The second wastest.ream is principally comprised c.f a spring
which flows E-� W along the northern edge (the low side) of
the exposed granite. This spring receives discharges of
cooling water from at least two diamond saws. The spring
then flows through a low-lying area of cattails where much
of the inorganic material drops out. The spring then flows
to the River, by-passing the settling ponds. This
wastestream used to flow through the ponds, but the
Permittee was advised to keep the streams segregated by Land
Quality Section personnel. The advice was given because the
stream also receives the run-off from the 97 acre impervious
granite surface, such that every time it rained, the run-off
"blew -out" the accumulated sediment in the basins.
5. Sludge handling and disposal scheme:
"Sludge" is drag -lined from the settling ponds and disposed
of on -site. The "sludge" consists of inorganic matter
(stone fragments and dust).
6. Treatment plant classification: (attach completed rating

PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction
Grants Funds (municipals only)? N/A
2. Special monitoring requests: None
3. Additional effluent limits requests: None
4. Other:

PART IV - EVALUATION AND RECOMMENDATIONS
An Agent of the Company was notified during the site visit
that all water generated from cutting and polishing operations
must be routed through the settling basins. We do agree that the
run-off generated from the quarry face should not be routed
through the ponds, as hydraulic overload would result in
short-circuiting, insufficient settling time, and a resultant
turbid discharge.
The discharges from the two diamond saws which currently
reach the spring should be piped to a point where they will flow
into the permitted wastewater ponds. In this manner, stormwater
and process water can remain segregated.
The Region recommends the Permit be reissued.

TOXICITY TESTING REQUIREMENT
The effluent discharge shall at no time exhibit chronic toxicity using
test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay proce-
dure (North Carolina Chronic Bioassay Procedure - Revised *February 1987) or
subsequent versions.
The effluent concentration at which there may be no observable inhibi-
tion of reproduction or significant mortality is 3 % (defined as treatment
two in the Nor h Carolina procedure document). The permit holder shall
perform v&i to monitoring using this procedure to establish compliance
with the permit ndition. The first test will be performed within thirty
days from issuance of this permit. Effluent sampling for this testing shall
be performed at the NPDES permitted final effluent discharge below all
treatment processes, including chlorination. There may be no dechlorination
of the effluent sample prior to testing.
All toxicity testing results required as part of this permit condition
will be entered on the Effluent Discharge Monitoring Form (MR-1) for the
month in which it was performed, using the appropriate parameter code.
Additionally, DEM Form.AT-1 (original) is to be sent to the following
address:
Attention: Technical Services Branch
North Carolina Division of
Environmental Management
P.O. Box 27667
Raleigh, N.C. 27611
Test data shall be complete and accurate and include all supporting chemi-
cal/physical measurements performed in association with the toxicity tests,
as well as all dose/response data. Total residual chlorine must be measured
and reported if employed for disinfection of the waste stream.
Should any test data from this monitoring requirement or tests per-
formed by the North Carolina Division of Environmental Management indicate
potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited docu-
ment, such as minimum control organism survival and appropriate environmen-
tal controls, shall constitute an invalid test and will require immediate
retesting. Failure to submit suitable test results will constitute a fail-
ure of permit condition.
