Attention: Charles Weaver
Subject: Meridian Industries, Inc.
Ranlo Facility
Dear Mr. Weaver:
Your e-mail of August 11, 2010, advised Meridian Industries, Inc. that a Certificate of Coverage issued
to the former owner of the Ranlo facility, Dixie Yarn Company, had expired. This Certificate of
Coverage included the discharge from cooling towers and compressor condensate.
Please be advised that these discharges have been discontinued. The condensate from all compressors
and the overflow from cooling towers have been plumbed into the municipal sewer system. The
discharge lines from this equipment, which were previously directed into a small lagoon, have been
permanently closed. The small lagoon remains on site. It now only collects, and subsequently
discharges, stormwater which is covered under our General Stormwater Permit(NCG 170000). Plans
have been made, but have not yet been initiated, to permanently close the lagoon
In April, 2007, samples were collected from the lagoon to confirm that no compressor condensate was
reaching the environment. Laboratory analysis found that no hydrocarbons were present.
Accordingly, no action has been taken, nor is any planned, to renew the previous NPDES permit.
Please advise if additional information or action is needed.
Sincerely,
MERIDIAN INDUSTRIES, INC.

RE: PERMIT MODIFICATION
NPDES PERMIT NO. NCG500237
DIXIE YARNS —REX PLANT #1
GASTON COUNTY
U v Mr. Goodrich:
z
A This letter is a request to modify the existing NPDES permit for a second
3 outfall at our Rex plant. The permit covers non-contact cooling water, condensate,
°
x and cooling tower blow down for the air conditioning system. This outfall is shown
,
u on the attached maps. It is noted that the discharge is from the same type of
equipment that covers the existing outfall (001). Also, sampling of the additional
— outfall has already been conducted.
This additional outfall has always been there but was overlooked because it
W a was a small pipe buried in the ground and emptied into a pipe going under the main
road. Please advise of any further information required to modify this permit and
your help is greatly appreciated. Call me at 423-493-7286 as required.
Sincerely,

General Permit NCG500000

Gaston County
Dear Permittee:
The Division of Environmental Management has recently evaluated all existing individual permits for potential
coverage under general permits currently issued by the Division. 15A N.C.A.C. 2H .0127 allows the Division to
evaluate groups of permits having similar discharge activities for coverage under general permits and issue
coverage where the Division finds control of the discharges more appropriate in this manner. The Division has
determined that the subject discharge qualifies for such coverage. Therefore, the Division is hereby issuing the
subject Certificate of Coverage under the state-NPDES general permit no. NCG500000 which shall void NPDES
Permit NC0075841. This Certificate of Coverage is issued pursuant to the requirements of North Carolina and the
US Environmental Protection Agency Memorandum of Agreement dated December 6,1983 and as subsequently
amended.
If any parts,measurement frequencies or sampling requirements contained in this general permit are unacceptable to
you, you have the right to submit an individual permit application,associated processing fee and letter requesting
coverage under an individual permit. Unless such demand is made,this decision shall be final and binding. Please
take notice this Certificate of Coverage is not transferable. Part II, E.4. addresses the requirements to be followed
in case of change of ownership or control of this discharge.
In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions, the
Permittee shall take immediate corrective action, including those as may be required by this Division, such as the
construction of additional or replacement wastewater treatment or disposal facilities. Construction of any
wastewater treatment facilities will require issuance of an Authorization to Construct from this Division.
Failure to abide by the requirements contained in this Certificate of Coverage and respective general permit may
subject the Permittee to an enforcement action by the Division of Environmental Management in accordance with
North Carolina General Statute 143-215.6A to 143-215.6C. Please note that the general permit does require
monitoring in accordance with federal law. The monitoring data is not required to be submitted to the Division
unless specifically requested,however, the permittee is required to maintain all records for a period of at least
three (3) years.

Certificate of Coverage No. NCG500237
The issuance of this Certificate of Coverage is an administrative action initiated by the Division of
Environmental Management and therefore,no fees are due at this time. In accordance with current rules,there
are no annual administrative and compliance monitoring fees for coverage under general permits. The only fee
you will be responsible for is a renewal fee at the time of renewal. The current permit expires July 31,1997.
This coverage will remain valid through the duration of the attached general permit. The Division will be
responsible for the reissuance of the general permit and at such time,you will be notified of the procedures to
follow to continue coverage under the reissued permit. Unless you fail to follow the procedures for continued
coverage,you will continue to be permitted to discharge in accordance with the attached general permit.
The issuance of this Certificate of Coverage does not preclude the Permittee from complying with any and all
statutes,rules,regulations,or ordinances which may be required by the Division of Environmental Management
or permits required by the Division of Land Resources,the Coastal Area Management Act or any Federal or
Local other governmental permit that may be required.

may be required of the permittee. The filing of a request by the permittee for
a permit modification, revocation and reissuance, or termination, or a
notification of planned changes or anticipated noncompliances, does not stay
any permit condition.
5. Toxic Pollutants
Notwithstanding Part II, A-4 above, if a toxic effluent standard or prohibition
(including any schedule of compliance specified in such effluent standard or
prohibition) is established under Section 307(a) of the Act for a toxic
pollutant which is present in the discharge, if such standard or prohibition
is more stringent than any limitation for such pollutant in this permit, this
permit shall be revised or modified in accordance with the toxic effluent
standard prohibition and the permittee so notified.
The permittee shall comply with effluent standards or prohibitions established
under Section 307(a) of the Clean Water Act for toxic pollutants within the
time provided in the regulations that establish those standards or prohibitions,

SECTION D. REPORTING REQUIREMENTS
1. Change in Discharge
All discharges authorized herein shall be consistent with the terms and
conditions of this permit. The discharge of any pollutant identified in
this permit more frequently than or at a level in excess of that authorized
shall constitute a violation of the permit. Any anticipated facility
expansions, production increases, or process modifications which will result

Part II
Page 7 of 14
in new, different, or increased discharges of pollutants must be reported by
submission of a new NPDES application or, if such changes will not violate
the effluent limitations specified in this permit, by notice to the DEM of
such changes. Following such notice, the permit may be modified to specify
and limit any pollutants not previously limited.
2. Anticipated Noncompliance
The permittee shall give notice to the Permit Issuing Authority of any planned
change in the permitted facility or activity which may result in noncompliance
with permit requirements. Any maintenance of facilities, which might
necessitate unavoidable interruption of operation and degradation of effluent
quality, shall be scheduled during noncritical water quality periods and carried
out in a manner approved by the Permit Issuing Authority.

SECTION E. DEFINITION
1. Permit Issuing Authority
The Director of the Division of Environmental Management.
2. DEM or Division
Means the Division of Environmental Management, Department of Natural
Resources and Community Development.

Part II
Page 11 of 14
3. EMC:
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as
amended, 33 USC 1251, et. seq.
5. Mass/Day Measurements
a. 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 sample and measured, divided by the number
of daily discharges samples 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 "Daily Average" or "Monthly Average" in Part I of the
permit.
b. The "weekly average discharge" is defined as the total mass of
all daily discharges sampled and/or measured during the calendar week
(Sunday-Saturday) on which daily discharges are sampled and measured,
divided by the number of daily discharges samples 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 sample 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 12 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
samples 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" or
"Daily Average" under "Other Limits" in Part 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 day. 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 daily 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 year. This limitation
is identified as "Annual Average" under "Other Limits" in Part I of the
permit.

Part II
Page 13 of 14
7. Other Measurements
a. Flow, (MGD): 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.
8. Types of Samples
a. Composite Sample: These samples consist of grab samples collected at
equal intervals and combined proportional to flow, a sample continuously
collected proportionally to flow, or equal volumes taken at varying time
intervals. If a composite sample is obtained from grab samples, the
following requirements apply. The intervals between influent grab
samples shall be no greater than hourly. Intervals between effluent grab
samples shall be no greater than hourly except where the detention time
of the wastewater in the facility is greater than 24 hours, in which
case, the interval between grab samples shall be no greater in number of
hours than the detention time in number of days; provided, however, in
no case may the time between effluent grab samples be greater than six
hours nor the number of grab samples less than four during any discharge
period of 24 hours or less.
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.
9. Calculation of Means
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).
c. 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.

Part II
Page 14 of 14
10. Calendar Day
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.

NOTE: Blowdown will be discontinued when Betz Entec 346 is shot fed. Blowdown
will be resumed only after the concentration of active product has reached
2 ppm as measured by free available chlorine (maximum of 0.6 ppm). The
DR is based on the concentration of active product in the water at the time
blowdown is resumed.
Hydrolysis of the sodium dichloro-s-triazinetrione dihydrate results in the
formation of chlorocyanuric acid and hypochlorous acid. The chlorocyanurate
acid further hydrolyzes to produce additional hypochlorous acid and cyanurate.
Fish toxicity studies have been run on cyanuric acid because this is the major
breakdown product. Delaware Dace minnows were exposed for 48 hours to the
concentrations of cyanuric acid from 0.5-3,000 mg/L. No mortalities were
encountered in any solution of this material. Studies on the biodegradation
of cyanuric acid were published in Applied Microbiologic Microbiology, Volume
28, Number 6, December, 1974. The .data indicated that cyanuric acid will
readily breakdown to carbon dioxide and ammonia in conventional sewage
collection and treatment facilities, septic vaults and drain fields.
