Subject: Modification of NPDES Permit NC0086169
Midland Plant
Cabarrus County
The Division received your request to modify the subject permit on August 30, 2002. An earlier permit
modification issued by the Division on August 12, 2002) included a Supplement to Permit Cover Sheet from a
previous version of the permit. This modification corrects the error by replacing that outdated version with the
correct version of the page (from the permit modification issued October 31, 2001).
Your request also asked for clarification regarding the requirement (Part I. A. (7.)) to conduct a benthic
macroinvertebrate study prior to submission of the permit renewal application for this facility (due no later than May
4, 2003). The Division's intention was for Corning to perform the study after expansion of the WWTP to a
permitted flow of 0.142 MGD. If the expansion has not taken place, the study is not required.
Please find enclosed the revised pages, which should be inserted into your permit. The old pages may then be
discarded. All other terms and conditions contained in the original permit remain unchanged and in full effect. This
permit modification is issued under the requirements of North Carolina General Statutes 143-215.1 and the
Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency.
If any parts, measurement frequencies or sampling requirements contained in this permit modification are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days
following receipt of this letter. This request must be a written petition conforming to Chapter 150B of the North
Carolina General Statutes, filed with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North
Carolina 27699-6714). Unless such demand is made, this decision shall be final and binding.
If you have any questions concerning this permit modification, please contact Charles Weaver of the NPDES

Attachment to
Engineer's Certification for Construction of Wastewater
Treatment Facilities - Second Submittal
Certification This Engineer's Certification for Construction of Wastewater Treatment
Basis Facilities is for Project No. 086169ACB for Corning Incorporated,
Concord Facility, Waste Abatement System Expansion.
The wastewater generated by the different processes within the
Concord Facility will be treated as they are generated. The facility
processes will be started -up in an orderly sequence and each
subsystem in the wastewater treatment area will be placed in
operation as required to treat each type of wastewater as it is
produced.
The construction of the wastewater subsystems have been scheduled
to correspond to the generation of process wastewater by the facility
processes. Thus, the entire wastewater treatment system is not
completed and ready for operation. We have concentrated our efforts
to built and test the subsystems to meet a start-up schedule that
parallels the start-up schedule of the facility process areas.
To address the process start-up requirements the subsystems in the
wastewater treatment area will be started in discrete parts we have
termed Sequences.
System As outlined in the first certification submittal, we have
Update successfully completed the start-up of Sequence 1 B — treatment
of cooling tower blowdown from the Concord II HVAC cooling
tower. Due to the mode of operation of the cooling tower, we
have been treating the blowdown in a "batch" operation. We
anticipate initiating a continuous mode of blowdown treatment
the week of 5/7/2001.

Concord Facility Page 1 of 4
Contract No. 78600.001
May 7, 2001

Start-up This second certification submittal includes the wastewater treatment
Activities subsystem start-up of Sequence 1A which will combine with the
wastewater from Sequence 1 B (this start-up has been successfully
completed). In this start-up sequence we will be treating the
combined streams of 1) cooling tower blowdown from the Concord II
HVAC cooling tower, 2) Neutralization System No.1 effluent, and 3)
cooling tower blowdown from the Concord I HVAC cooling. The
combined streams will be treated with sodium bisulfite, as required for
the removal of chlorine. The pH will be within acceptable values (6 —
9 pH units) due to the HVAC cooling towers and Neutralization System
No. 1 control range. The suspended solids level in the cooling tower
blowdown should be low due to the HVAC cooling tower control range.
If required, we have the capability of removing any suspended solids
in the No. 3 lamella.
The following paragraphs generally describe the components of the
subsystem which will be required for Sequence 1 A & 1 B. These
components are described in detail in ATC No. 086169ACB.
We will be ready to accept the combined Neutralization System
No. 1 and Cl & Cll HVAC Cooling Tower Blowdown in Sequences
1A & 1B on Friday, May 11, 2001.
As the remaining wastewater subsystems are built and
tested, the corresponding Engineer's Certification will be
submitted in accordance with the Division requirements
prior to operation of those subsystems.

System Solids Removal Unit (See Figure 3)
Operation
Overview The inlet header to the Surge/Blend Tank provides for premixing of
non -contact cooling tower blowdown, treated effluent from
Neutralization System No. 1, treated effluent from Neutralization No. 2,
and softener regeneration wastewater prior to entering the tank. This
provides for thorough mixing of the wastewater inlet flows and sodium
bisulfite for chlorine removal in a static mixer. From the Surge/Blend
Tank the blended wastewater is pumped to Lamella Separator No. 3
for removal of suspended solids and is then pumped to the existing
Effluent Lift Station. Any off -spec (pH) wastewater is automatically
diverted to an Off Spec Tank No. 2 and then pumped back to
Equalization Tank No. 2 at a controlled rate for re -treatment. Other
off -spec (turbidity or ORP) wastewater is automatically diverted back
to the Surge/Blend Tank for re -processing through the chlorine
removal and suspended solids removal unit operations.
An existing Process Effluent Tank is located at the Effluent Lift Station
for storage of wastewater during the times wastewater cannot be
pumped to the river. Wastewater stored in the Process Effluent Tank is
returned, by gravity, to the Effluent Lift station.
Settled solids in the Lamella Separator are periodically pumped from
the lamella to the Sludge Thickening Tank No. 3 and then from the
tank to the existing Sludge Holding Tank for disposal.

A(6). Pollutant Analysis Condition
The Permittee shall conduct a test for pollutants once per permit cycle at the effluent from the
treatment plant. The discharge shall be evaluated as follows:
1) A pollutant analysis of the effluent must be completed using EPA approved methods for the
following analytic fractions:
(a) purgeables (i.e., volatile organic compounds);
(b) acid extractables;
(c) base/neutral extractables;
(d) organochlorine pesticides and PCBs;
(e) herbicides; and
(fl metals and other inorganics.
The Annual Pollutant Analysis Monitoring (APAM) Requirement Reporting Form A and accompanying
memo describes the sampling and analysis requirements and lists chemicals to be included in the
pollutant analysis. This monitoring requirement is to be referred to as the "Pollutant Analysis
Monitoring Requirement" (PAM).
2) Other significant levels of organic chemicals must be identified and approximately quantified. For
the purpose of implementing this requirement, the largest 10 GC/MS peaks in the purgeable,
base/neutral extractable, and acid exractable fractions (or fewer than 10 if less than 10
unidentified peaks occur) for chemicals other than
those specified on the APA Requirement Reporting Form A should be identified and approximately
quantified as stated in the APAM Reporting Form A instructions. This part (item 2) of the APAM
requirement is to be referred to as the "10 significant peaks rule").
A(7). Biological Monitoring Condition
The Permittee shall conduct an upstream and downstream benthic macroinvertebrate survey
beginning June 2004 and lasting through September 2004. A report of the findings of this survey
shall be completed and included with the permit application package at the time of permit renewal.
For technical assistance regarding this permit requirement, please contact the Division's Biological
Assessment Unit at [phone].
A(8). Stormwater Monitoring, Controls and Limitations for Permitted
Discharges

Permit NCO086169
a. Site Plan: The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of regulated
stormwater discharges. The site plan shall contain the following:
(1) A general location map (USGS quadrangle map, or appropriately drafted equivalent map),
showing the facility's location in relation to transportation routes and surface waters, and the
name of the receiving water(s) to which the stormwater outfall(s) discharges. If the discharge is to
a municipal separate storm sewer system, the name of the municipality and the ultimate
receiving waters, and accurate latitude and longitude of the point(s) of discharge must be shown.
(2) A narrative description of storage practices, loading and unloading activities, outdoor process
areas, dust or particulate generating or control processes, and waste disposal practices.
(3) A site map (or series of maps) drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials, disposal areas, process areas, and loading
and unloading areas), drainage structures, drainage areas for each outfall and activities
occurring in the drainage area, building locations and impervious surfaces, the percentage of
each drainage area that is impervious. For each outfall, a narrative description of the potential
pollutants which could be expected to be present in the regulated stormwater discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility during the 3
previous years and any corrective actions taken to mitigate spill impacts.
(5) Certification that the stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. The certification statement will be signed in accordance with the requirements found
in Part II. B. 11.
b. Stormwater Management Plan: The stormwater management plan shall contain a narrative
description of the materials management practices employed which control or minimize the
exposure of significant materials to stormwater, including structural and non-structural
measures. The stormwater management plan, at a minimum, shall incorporate the following:
(1) A study addressing the technical and economic feasibility of changing the methods of operations
and/or storage practices to eliminate or reduce exposure of materials and processes to
stormwater. Wherever practicable the permittee should consider covering storage areas, material
handling operations, manufacturing or fueling operations to prevent materials exposure to
stormwater. In areas where elimination of exposure is not practicable, the stormwater
management plan shall document the feasibility of diverting the stormwater runoff away from
areas of potential contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials, storage of
Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water
priority chemicals, or storage of hazardous materials to prevent leaks and spills from
contaminating stormwater runoff. If the secondary containment devices are connected directly to
stormwater conveyance systems, the connection shall be controlled by manually activated valves
or other similar devices [which shall be secured with a locking mechanism] and any stormwater
that accumulates in the containment area shall be at a minimum visually observed prior to
release of the accumulated stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. Records documenting the individual making the observation, the description of
the accumulated stormwater and the date and time of the release shall be kept for a period of five
years.
(3) A narrative description of Best Management Practices (BMPs) to be considered such as, but not
limited to, oil and grease separation, debris control, vegetative filter strips, infiltration and
stormwater detention or retention, where necessary. The need for structural BMPs shall be based
on the assessment of potential of sources contributing significant quantities of pollutants to
stormwater discharges and data collected through monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be taken to limit
- % or prevent erosion associated with the stormwater systems.

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 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 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 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

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. 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 1 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.
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 1 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.

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.
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:
(1) 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 system, or
(3) a single, 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 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
M.
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.

Dear Mr. Goodrich:
CORNING
Corning, Inc., Concord Plant is making preparations for a maintenance shutdown period
the week of December 18, 2000. Part of the activities during this period will be the
draining and flushing of the non -contact cooling water basin. This is accomplished to
prevent malfunctions of the non -contact cooling water pumping system. The basin holds
60,000 gallons of water. 40,000 gallons of water from our FireWater Tank would be
used to flush the basin.
We are currently permitted to discharge non -contact cooling tower blowdown from
normal operations to Outfall 003. Outfall 003 also permits the discharge of our industrial
wastewater. The time established to drain and flush the non -contact cooling water basin
is six (6) hours, followed by another six (6) hours to refill the basin. This twelve- (12)
hour time period is necessary to reduce the down time of our HVAC system. Process
equipment that generates heat in the production area will still be running during this time.
Without the HVAC system operational, the heat generated by this equipment will shut
down portions of the computer system of the plant. Based on this short shutdown
duration and the current capacity of our pumping system for Outfall 003, it is not possible
to discharge this water through Outfall 003.
The proposed plan is to discontinue the addition of any additives to the non -contact
cooling water at a time prior to draining the basin to allow the additives to degrade
(please see attached recommendations from our supplier, BetzDearborn). We will
monitor pH and total residual chlorine.
We would like to discharge the 100,000 gallons (includes flush from the FireWater Tank)
to Outfall 002. Outfall 002 is designed as a detention pond. Our current permit allows us
to discharge stormwater and humidification boiler blowdown to Outfall 002. We are
currently required to monitor flow, temperature and total residual chlorine on a semi-
annually basis at Outfall 002.

This discharge will be an annual occurrence in the future during our maintenance
shutdown operations. These shutdowns occur at the end of each year (usually prior to the
Christmas holidays). As we expand, adding more cooling towers, the flow may increase.
We are requesting a modification to our current permit, in the form of a Special
Condition, to allow the annual discharge of the non -contact cooling water basin and
associated flush water to Outfall 002. We propose to suspend the use of water treatment
chemical feed as suggested by BetzDearborn prior to discharge.
Based upon the time usually required for a permit modification to be issued and the short
lead time we have for the 2000 shutdown, we are requesting initial approval for this
year's process as soon as possible. I apologize for the inconvenience of this short notice.
Please feel free to contact me if you have any questions or require further information. I
can be reached at phone number [phone]

RE: HVAC Cooling Tower Shutdown
Bill:
cc: Tom Hall
Jaime Ritchie
Kevin Kelley
We have been asked to present to Corning an operating procedure to suspend the water
treatment chemical feed to the HVAC Cooling Tower. to allow for direct discharge into
the holding ponds during the December shutdown. Currently BetzDearborn is supplying
the following chemicals to Cooling Tower system:
➢ BetzDearborn Spectrus OX1200-Biocide/Chlorine residual
➢ BetzDearborn Spectrus BD152-Biosurfactant/No detectable residual
➢ BetzDearborn Dianodic DN300-Corrosion Inhibitor/Ortho-phosphate residual
➢ BetzDearborn AF740-Antifoam/No detectable residual
➢ BetzDearborn Depositrol PY505-Polymeric Dispersant/No detectable residual
Fed to the Cooling Tower makeup water:
➢, BetzDearborn F1oGard MS6206-Process Water Corrosion Inhibitor/0-PO4 residual
These chemicals are fed to the tower at a specific dosage based on a function of the
amount of water that is being bled from the system. The chemicals become concentrated
within the tower as a result of cycling. In order to reduce the concentrations of these
chemicals within the tower and allow for the water to be deemed acceptable under your
permit restrictions the feeds of the water treatment products will need to be suspended
prior to shutdown. In order to help dissipate residuals the tower blowdown rates should
be increased during the days leading up to the shutdown. We recommend the following
schedule:
1. 4 Days before shutdown- decrease cycles of concentration by 50%. This tower is
designed to run at 5 cycles. Increase blowdown to lower this level to no more than 3

cycles. Stop Spectrus BD152 and Depositrol PY505 feeds at this time. The lower
cycles will decrease the demand for each of these products.
2. 3 Days before shutdown- stop Dianodic DN300 feed at the tower and the feed of the
F1oGard MS6206 at the Industrial Process Water Makeup. This will allow the
Phosphate residual to dissipate completely prior to discharge to the ponds. Continue
running at less than 3 cycles of concentration.
3. 2 Days before shutdown- stop Spectrus OX1200 feed and AF740 feed at the Tower.
The chlorine residual should be 0.0 PPM without the feed of this product.
4. 1 Day before shutdown and day of- the effluent from the Cooling Tower should be
closely monitored by the Plant personnel to assure the chlorine residual and the
phosphate residuals are below the permit specifications. Total suspended solids
should also be closely watched. 'At first indication of any permit excess, the flow
should be suspended to the ponds.
❖ The feed of the FloGard MS6206 should be resumed as soon as the HVAC Tower
stops receiving makeup water flow.
Due to variations in operating loads and seasonal temperature changes it is difficult to
accurately quantify the amount of water that will need to be bled to achieve our desired
operating conditions. These rates can be estimated using the following formulas.
Blowdown (GPM)= Evaporation Rate (GPM)
Cycles of Concentration — 1
Evaporation (GPM) = OT(°F) * Recirculation Rate (GPM)
1,000
In summary, by increasing the tower blowdown rates and stopping the feed of the water
treatment chemicals days before the shutdown, the water within the system at the time of
the shutdown should be of the same chemical composition as the city water makeup.
This will be verified by real time chemical monitoring by Plant personnel.
We do not foresee any problems with the short-term suspension of water treatment
chemicals during this time period.
Thank you for allowing BetzDearbom to provide this recommendation to Corning
Incorporated. Should you have any questions concerning this report please do not
hesitate to contact me. I can be reached at 1-888-716-6198.

the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions. The tests will be performed during the months of
January, April, July, and October. Effluent sampling for this testing shall be performed at the
NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below
the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the
two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
Q
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -
February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter
code TGP313 for the pass/fail results and THP313 for the Chronic Value. Additionally, DWQ Form AT-3

A(6). Pollutant Analysis Condition
The Permittee shall conduct a test for pollutants once per permit cycle at the effluent from the
treatment plant. The discharge shall be evaluated as follows:
1) A pollutant analysis of the effluent must be completed using EPA approved methods for the
following analytic fractions:
(a) purgeables (i.e., volatile organic compounds);
(b) acid extractables;
(c) base/neutral extractables;
(d) organochlorine pesticides and PCBs;
(e) herbicides; and
(fl metals and other inorganics.
The Annual Pollutant Analysis Monitoring (APAM) Requirement Reporting Form A and accompanying
memo describes the sampling and analysis requirements and lists chemicals to be included in the
pollutant analysis. This monitoring requirement is to be referred to as the 'Pollutant Analysis
Monitoring Requirement" (PAM) .
2) Other significant levels of organic chemicals must be identified and approximately quantified. For
the purpose of implementing this requirement, the largest 10 GC/MS peaks in the purgeable,
base/neutral extractable, and acid exractable fractions (or fewer than 10 if less than 10
unidentified peaks occur) for chemicals other than
those specified on the APA Requirement Reporting Form A should be identified and approximately
quantified as stated in the APAM Reporting Form A instructions. This part (item 2) of the APAM
requirement is to be referred to as the "10 significant peaks rule").
A(7). Biological Monitoring Condition
The Permittee shall conduct an upstream and downstream benthic macroinvertebrate survey
beginning June 2004 and lasting through September 2004. A report of the findings of this survey
shall be completed and included with the permit application package at the time of permit renewal.

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.
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:
(1) 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 system, or
(3) a single, 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 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.

treatment facilities which causes them to become inoperable, or substantial and permanent
loss of natural resources which can reasonably be expected to occur in the absence of a
bypass. Severe property damage does not mean economic loss caused by delays in
production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which -does not cause effluent limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient operation. These
bypasses are not subject to the provisions of Paragraphs c. and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall
submit prior notice, if possible at least ten days before the date of the bypass; including an
evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
required in Part II, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against
a permittee for bypass, unless:
(A) Bypass was unavoidable to. prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes or maintenance during normal periods of
equipment downtime. This condition is not satisfied if adequate backup equipment should
have been installed in the exercise of reasonable engineering judgment to prevent a bypass
which occurred during normal periods of equipment downtime or preventive maintenance;
and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.

Part II
Page 9 of 14
5. Upsets
a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors beyond the
reasonable control of the permittee. An upset does not include noncompliance to the extent
caused by operational error, improperly designed treatment facilities, inadequate treatment
facilities, lack of preventive maintenance, or careless or improper operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with such
technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs, or other relevant evidence that:
(1) An upset occurred and that the permittee can identify the cause(s) of the upset;
(2) The permittee facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this permit.
(4) The permittee complied with any remedial measures required under Part I1, B. 2. of this
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has
the burden of proof.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of
wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such
as to prevent any pollutant from such materials from entering waters of the State or navigable
waters of the United States. The permittee shall comply with all existing federal regulations
governing the disposal of sewage sludge. Upon promulgation of 40 CFR Part 503, any permit issued
by the Permit Issuing Authority for the utilization/disposal of sludge -may be reopened and
modified, or revoked and reissued, to incorporate applicable requirements at 40 CFR Part 503. The
permittee shall comply with applicable 40 CFR Part 503 Standards for the Use and Disposal of
Sewage Sludge (when promulgated) within the time provided in the regulation, even if the permit
is not modified to incorporate the requirement. The permittee shall notify the Permit Issuing
Authority of any significant change in its sludge use or disposal practices.
7. Power Failures
The permittee is responsible for maintaining adequate safeguards as required by DEM Regulation,
Title 15A, North Carolina Administrative Code, Subchapter 2H, .0124 Reliability, to prevent the
discharge of untreated or inadequately treated wastes during electrical power failures either by
means of alternate power sources, standby generators or retention of inadequately treated effluent.

Part II

Subject: Draft NPDES Permit

Midland Fiber Facility
Cabarrus County
Dear Ms. Hannon:
The Division has completed its draft of the NPDES discharge permit for the above referenced
facility. The following are major points in the attached draft permit that you should take notice of:
This permit has been drafted with three independent outfalls, labeled 001, 002 and 003.
Outfall 001 is for the discharge of stormwater and non -contact cooling water. Outfall 002 is
for the discharge of stormwater and boiler blowdown. Outfall 003 is for the discharge of
process wastewater associated with the manufacturing process.
The sampling point for outfalls 001 and 002 should be upstream- of their combination with
stormwater. The sampling point for flow at outfall 003 should be upstream of the internal
outfall of non -contact cooling water and boiler blowdown. All other parameters required at
outfall 003 shall be monitored via samples collected at the final discharge location..
This draft permit includes an acute toxicity test requirement for outfall 003. Division staff have
determined that due to the brine nature of the discharge, an acute toxicity test will be the most
protective of the receiving water. Biocide worksheet 101 need not be completed if all biocide
containing cooling waters are discharged through outfall 003 as the toxicity test serves the
purpose of the biocide worksheet. However, as long as biocide containing cooling waters are
discharged through outfall 001, biocide worksheet 101 must be completed and submitted to the
Division for approval.
® This draft permit authorizes the discharge of both stormwater and wastewater. Part II of this
permit is divided into stormwater conditions and wastewater conditions and establishes all
additional requirements for both types of discharge.

Visual Monitoring
Visual monitoring requires a qualitative visual inspection of each stormwater outfall, regardless of representative
outfall status, for the purpose of evaluating the effectiveness of the Stormwater Pollution Prevention Plan and
assessing new sources of stormwater pollution. No analytical tests are required. Visual monitoring of stormwater
outfalls does not need to be performed during a representative storm event.

PART Iv - EVALUATION ND RECOMMENDATIONS
Corning, Inc. requests the issuance of an NPDES Permit for
the discharge of both process water and non -contact cooling slater
from a facility presently under construction in southern Gabarrus
County.
The process water discharge (outfall 00311, will contain the
following sources of wastewater:
1. Rlowdown from pollution abatement equipment.
?. Water softener from area floor drains.
3. Water softener blowdown.
4. Cooling tower blowdo*-•,n.
5. Some stormwater.
The proposed method of treatment of the process water will
he by flocculation and pH adjustment (no plans have as yet been
received for the proposed WWTP) . -

Page Four
The two (2) cooling water outf,alls (001 & 002) will leave
the site only after passing through a wet detention basin. During
periods of infrequent rainfall these basins make hold little, if
any water. However, during wet -weather, these basins may hold
substantial quantities of water (both cooling water and
stormwater). Therefore, the potential_ exists for a considerable
amount of dilution prior to discharge. Most of the site's
stormwater has been channelled around the detention ponds,
however, there will still be a considerable quantity that enters
the ponds either directly or indirectly:
Corning is expected to have three (3) different types of
discharges: process water, cooling water, and stormwater. it is
recommended that the Company be issued only one (1) NPDES Permit,
which will simplify the permitting process and possibly eliminate
tracking confusion. Corning staff have discussed this option with
the writer and they have no objection.
Pending receipt and approval of the WLA, it is recommended
that an NPDES Permit be issued as requested.

PROPOSED MODIFICATION TO OUTFALL DSN002
The information listed below for DSN002 consists of the only changes proposed to the existing
outfall DSN002. There are no modifications being proposed for DSN001.
The humidification boiler blowdown discharge flow rate to the South Stormwater Management
Pond will increase from 960 gal/day to 3, 456 gal/day (maximum daily and average daily).
Estimates on all other characteristics of the non -process effluent have not changed from those in
the original application.
The stormwater drainage area for outfall DSN002 will increase from 28.8 acres to 31.45 acres
(total) and from 6.6 acres to 13.0 acres (impervious surfaces). The new peak flow estimated for a
50 year storm is 76.9 cubic feet per second. The South Detention Basin will be slightly modified
to handle the additional stormwater runoff. See Attachment C for the South Detention Basin
Layout Plan for the proposed modifications. Estimates on all other characteristics of the
stormwater runoff have not changed from those in the original application.

DESCRIPTION OF SITE DRAINAGE CONTROLS
Introduction
The Corning Incorporated - Concord Facility currently operates one (1) NPDES outfall for process
wastewater discharges (DSN003) and two (2) NPDES outfalls for storm water and nonprocess
wastewater discharges (DSN001 and DSNO02). Also, there are currently three (3) exempt discharges
of storm water runoff from areas where no industrial activity occurs (e.g., parking lots).
A modification to the facility's current NPDES Permit is being applied for to modify the process and
non -process wastewater discharges from the facility via DSN003 (see Attachment A) and the
stormwater/non-process wastewater discharges via DSNO02 (see Attachment A) due to a proposed
expansion to the facility operations. There are no modifications proposed which would modify the.
discharge and the associate drainage controls to DSN001.
NPDES Permitted Outfalls
The NPDES outfall DSNO02 discharging only storm water and non -process wastewaters currently
receives runoff from 28.8 acres, 6.6 acres being impervious. Post -modification, outfall DSNO02 will
receive runoff from 31.45 acres, 13.0 acres being impervious (see Attachment B for an updated site
drainage map). The drainage area for DSNO02 is the southern portion of the plant site. All storm
water runoff from this drainage area and noncontact boiler blowdown are collected in the'South
Stormwater Management Pond prior to discharge to Clear Creek via DSN002.
The NPDES outfall DSNO03 currently discharges treated process wastewater and non -process
wastewaters to the Rocky River.
Storm Water Discharges Exempt From NPDES Permitting
Three (3) storm water discharges currently occur from areas free of industrial activity. These areas
are mainly parking lots and yard.
On the northeastern portion of the plant site, storm water from the exempt areas is collected in a small
detention basin located just east of the North Sedimentation Pond. On the northwestern portions of
the plant site, storm water from the exempt areas flows to a diversion ditch running northeast just
along the outside of the west boundary of the DSN001 drainage area depicted. in Attachment B. The
exempt storm water discharge exits the property just north of the North Sedimentation Pond to enter
an unnamed tributary of Muddy Creek via existing natural drainage paths.

On the southern portion of the plant site, storm water from the exempt areas flows to diversion
ditches running south along the outside of the east and west boundaries of the DSN002 drainage area
depicted in Attachment B. The exempt storm water discharge exits the property just south of the
South Stormwater Management Pond to enter an unnamed tributary of Clear Creek via existing
natural drainage paths.
A drawing depicting the exempt stormwater diversion ditch and detention basin was submitted with
the original NPDES Stormwater Permit application.
Site Drainage Controls
The runoff from the roofs and developed areas portions of the properties within the DSN001 and
DSN002 drainage areas is conveyed to the appropriate permitted ponds by a storm sewer system and
grassed swales. Details for the North Sedimentation Pond (dry pond) were provided with the original
NPDES Stormwater Permit application. Attachment C contains the and South Detention Basin (wet'
pond) Layout Plan as it has been modified for the proposed project.
At the plant site, Kirksey silt loam is found on gently sloping upward ridges, in depressions, and
around the head of intermittent drainage ways. Included with the soil are a few areas of Misenheimer
and Badin soils. Misenheimer soils are in slightly elevated positions near bedrock ledges at or near
the surface. Badin soils are found on small knolls and ridges. Misenheimer and Badin soils are
moderately well drained and well drained. Kirksey silt loam is moderately well drained.

BETZDEARBORN PRODUCT COMPOSITION
INFORMATION

The following information was provided by BetzDearborn concerning the chemical compositions
of the cooling tower additives. The additives are considered proprietary confidential chemicals by
BetzDearbom. For more information on any of the additives, please contact Ms. Helen Cerra,
Environmental Engineer - BetzDearborn, at [phone].
All of the following information on chemical additives, with the exception of Spectrus NX1104, was
provided with the original application. BetaDearborn has analyzed the additives and their
constituents for the potential to discharge all of the pollutants listed in Form C, Section II.16 and
Section II.17. All potential discharges have been identified in this application.
BetzDearborn has stated that Spectrus OX107 (formerly Bitrol 88P; oxidizing biocide) completely
breaks down in the cooling tower water; therefore, there should be no algicides, pesticides, etc.,
present in the effluent.
BetzDearborn has stated that Spectrus NX1104 (biocide) readily absorbs solids; therefore, the
bioavailablity and the expressed aquatic toxicity of the biocide are significantly reduced. Also,
Corning -Concord has performed toxicity testing (outside of their compliance requirements) with
Spectrus NXl 104. Toxicity testing will be performed per their compliance requirements later this
month. Results of the testing will be forward to NCDENR once received. Due to the toxicity testing
performed/being performed on the biocide, it was determined that the biocide worksheet would not
be necessary.

PRODUCT ENVIRONMENTAL FACTS
Tro188P)
Product Application
Spec bus D'
Betz Bio-Tr_ol 88P is a broad-spectrum
micobiocide containing 96% 1-bromo-3-
chloro-5,5-dimethylhydantoin (BCDMH) in
tablet form. Betz Bio-Trot 88P is used to
control algal, bacterial, and fungal slimes in
commercial and industrial cooling towers,
cooling ponds, influent water systems
including flow through filters, heat exchangers,
industrial water scrubbing systems, brewery
pasteurizers and industrial air washers
equipped with mist eliminators.
Proper treatment levels depend on the
severity of fouling in the system. Typically,
enough Betz Bio-Trol 88P is added to achieve
2-3 mg/L total halogen residual for 1 - to 4
hours daily (24-72 mg/L of Betz Bio-Trot 88P).
A BetzDearborn representative will assist in
developing the best application for your
installation.
When used in a once -through application, an
environmental risk occurs if the total halogen
residual in the effluent exceeds 0.1 mg/L.
Little risk exists in recirculating applications,
applications with extended residence times
and applications with effluent treatment
systems. Product spills are unlikely to result in
adverse environmental effects.

Biodegradability studies on the parent

FROM :BUIG ENVIRONMENTRL 215 9S3 2464 1997.05-16 10:06 #025 P.07
Reduction in the aqueous environmental
concentrations of the halogens is primarily due
the oxidant demand of the process waters.
Hypochlorous (HOCI) and hypobromous
(HOBr) acids and hypochlorite and
hypobromite ions will undergo photolytic
degradation when exposed to sunlight,
resulting in the formation of the significantly
less toxic Cr and Be ions. In addition,
aqueous concentrations of all oxidants are
reduced by volatilization and rapid reactions
with other chemicals and ions present in the
water.
Environmental Effects
Betz Bio-Trol 88P is acutely toxic to . aquatic
life at concentrations -exceeding 0.3 mg/L.
Since this product is a microbial control agent,
inhibition of algae, bacteria, and activated
sludge populations is expected. The inhibitory
effects are dependent on the pH of the
solutions. At 10 ppm and a pH of < 7.5, Betz
Bio-Trot 88P is 100% inhibitory to
microorganisms. This inhibition is reduced at
a pH of>7.5.
The dehalogentated by-product is significantly
less toxic to aquatic life. In addition, bromide
and chloride ions are considerably less toxic
than the active bromine and chlorine. As a
result, Betz Bio-Trol 88P will have no long
term impact on the aquatic environment.
Environmental Risk
The risk assessment was based on a dosage
of 72 mg/L Betz Bio-Trot 88P (2 - 3 mg/L total
halogen) in a once -through cooling system.
This application as well as lower dosages will
result in a significant risk to - the aqueous
environment if the combined chlorine and
bromine residuals exceed 0.1 mg/L in the
effluent. The risk is minimized in waters with
increased residence time, increased exposure
to sunlight, and a high oxidant demand.
The risk in recirculating systems and those
whose effluents are treated is very low, since
the increased residence time, increased
demand and waste treatment will usually
reduce the halogen residuals to below no -
effect levels. Since the product form is a solid,
little risk potential from spills or product
overfeeds exists:

Cabarrus County
Dear Mr. Hilton:
The Division issued NPDES permit number NCO086169 to Corning Incorporated for the above
referenced facility on November 14, 1997. In accordance with your request, the Division is forwarding
herewith permit modifications to the aforementioned permit. Specifically, the permit has been modified to
allow the discharge of approximately 1000 gallons per week of corrosion inhibitor laden water through outfall
001.
Although no effluent limitations have been installed for this outfall, monitoring will be required for
flow, suspended solids, residual chlorine, total phosphorus, temperature, and pH. Additionally, it is the
Division's expectation that controls for solids and residual chlorine will be installed. As a result of the low -flow
nature of this discharge, no Authorization to Construct will be required for the aforementioned control devices.
However, the Mooresville Regional Office should be contacted upon installation of these devices and prior to
discharge.
Enclosed please find the modified permit pages. The old pages should be discarded. This permit
modification is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the
Memorandum of Agreement between North Carolina and the U. S. Environmental Protection Agency dated
December 6, 1983.
Please take notice that this permit is not transferable. Part I1. EA. addresses the requirements to be
followed in case of change in ownership or control of this discharge. This permit does not affect the legal
requirement to obtain other permits which may be required by the Division of Water Quality or permits
required by the Division of Land Resources, Coastal Area Management Act or any other Federal or Local
government permit that may be required.

MEMORANDUM

From: Mark McIntire
NPDES Unit
Subject: Corning Incorporated
NCO086169 — Cabarrus County
Corrosion problem/resolution review
The Division received a package of information from Corning, Incorporated on October 20, 1998. Specifically, the
package was in support of a request to employ zinc'orthophosphate, a corrosion inhibitor. The following day, a fax was
received from Corning requesting that we stay our review of the original, submittal in lieu of a new proposal.
The Corning facility is a fiberoptic manufacturer with high chloride wastewater. The facility is presently experiencing a
corrosion problem in the carbon steel pipe. The alkalinity and pH of one of the cooling waters is causing unexpectedly
high galvanic corrosion. As opposed to entering zinc orthophosphate into all wastestreams, Corning is proposing to
flush their carbon steel lines with approximately 1000 gallons per week of potable water containing a proprietary BETZ
phosphate corrosion inhibitor. This 1000 gallons per week would discharge through outfall 001. Corning will install
treatment measures to abate chlorine and solids.

Dear Ms. Hanna -
Our records indicate that NPDES Permit No. NCO086169 was issued on April 14,
2000 for the discharge of wastewater to the surface waters of the State from your facility.
The purpose of this letter is to advise you of the importance of the Permit and the liabilities
in the event of failure to comply with the terms and conditions of the Permit. If you have
not already done so, it is suggested that you thoroughly read the Permit. Of particular
importance are Pages 4 and 5.
Pages 4 and 5 set forth the effluent limitations and monitoring requirements for your
discharge. Your discharge must not exceed any of the limitations set forth. The section
headed "Monitoring Requirements" describes the measurement frequencies, sample types
and sampling locations. Upon commencement of your discharge (or operation), you must
initiate the required monitoring. The monitoring results must be entered on reporting forms
furnished or approved by this Agency. If you have not received these forms, they should
be arriving shortly. If you fail to receive the forms, please contact this Office as quickly as
possible. I have enclosed a sample of the "Effluent" reporting form (DEM Form MR-1),
plus instructions for completing the form. It is imperative that all applicable parts be
completed, and the original and one copy be submitted as required.
Please be advised that an annual administering and compliance monitoring fee may
be required for your facility. You will soon be receiving a statement from our Raleigh
Office. It is imperative that the fee be paid in a timely manner so as to prevent enforcement
action or possible revocation of your permit.
The remaining parts of the Permit set forth definitions, general conditions and special
conditions applicable to the operation of wastewater treatment facilities and/or discharge(s).
The conditions include special reporting requirements in the event of noncompliance,
bypasses, treatment unit/process failures, etc. Also addressed are requirem

facilities. Any changes in operation of wastewater treatment facilities, quantity and type of
- wastewater: being treated or discharged, expansions --and/or upgrading of wastewater-.._ ..
treatment facilities must be permitted or approved by this Agency.
Failure to comply with the terms and conditions of an NPDES Permit subjects the
Permittee to enforcement action pursuant to Section 143-215.6 of the North Carolina
General Statutes. A civil penalty of up to $25,000 per violation (and/or criminal penalties)
may be assessed for such violations. If you find at any time that you are unable to comply
with the terms and conditions of the Permit, you should contact this Office immediately. A
Special Order by Consent (SOC) may be necessary while pursuing action to obtain
compliance.
As a final note, an NPDES Permit is normally issued for a five-year period. Permits
are not automatically renewed. Renewal requests must be submitted to this Agency no later
than 180 days prior to expiration. Please make note of the expiration date of your Permit.
This date is set forth on Page 1 of the Permit. Also note that .NPDES Permits are not
automatically transferable. If you, as the Permittee, cease to need this Permit, then you
should request that the Division of Water Quality rescind the Permit or request that DWQ
reissue the Permit to another party, if necessary.
As mentioned previously, the purpose of this letter is to advise you of the importance
of your NPDES Permit. Please read the Permit and contact this Office at 704/663-1699 in
Mooresville if you have any questions or need clarification. We look forward to providing
any assistance.

SPECIAL CONDITIONS
A. (5). ACUTE TOXICITY PERMIT LIMIT (QUARTERLY)
The permittee shall conduct acute toxicity tests on a quarterly_ basis using protocols defined as definitive in EPA
Document EPA/600/4-90/027 entitled " Methods for Measuring the Acute Toxicity of Effluents to Freshwater and
Marine Organisms." The monitoring shall be performed as a Fathead Minnow (Pimephales promelas) 24 hour static
test. The LC50 of this effluent using the previously stated methodology may at no time in any toxicity test be less
than 90%. Effluent samples for self -monitoring purposes must be obtained during representative effluent discharge
below all waste treatment. The tests will be performed during the months of January, April, July and October.
The parameter code for this test is TAE6C. 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, DWQ Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Water Quality
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity ' -
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the,
permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating .the facility
name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the
comment area of the form. The report shall be submitted to the Environmental Sciences Branch at the address cited
above.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will begin
immediately until such time that a single test is passed. Upon passing, this monthly test requirement will revert to
quarterly in the months specified above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this monthly test
requirement will revert to quarterly in the months specified above.
Should any test data from either these monitoring requirements or tests performed by the North Carolina Division of
Water Quality 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 document, such as minimum control organism
survival and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up
testing to be completed no later than the last day of the month following the month of the initial monitoring.
A. (6) POLLUTANT ANALYSIS CONDITION
The Permittee shall conduct a test for pollutants annually at the effluent -from the treatment plant. The discharge shall
be evaluated as follows:
1) A pollutant analysis of the effluent must be completed annually using EPA approved methods for the following
analytic fractions:
(a) purgeables (i.e., volatile organic compounds);
(b) acid extractables;
(c) base/neutral extractables;

monitoring requirement is to be referred to as the "Annual Pollutant Analysis Monitoring Requirement" (APAM).
2) Other significant levels of organic chemicals must be identified and approximately quantified. For the purpose
of implementing this requirement, the largest 10 GC/MS peaks in the purgeable, base/neutral extractable, and
acid exractable fractions (or fewer than 10 if less than 10 unidentified peaks occur) for chemicals other than
those specified on the APA Requirement Reporting Form A should be identified and approximately quantified as
stated in the APAM Reporting Form A instructions. This part (item 2) of the APAM requirement is to be
referred to as the "10 significant peaks rule").
A. (7) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in the "North Carolina
Ceriodaphnia Chronic Effluent.Bioassay Procedure," Revised November 1995, or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is
0.31% (defined as treatment two in the procedure document). The permit holder shall perform quarterly monitoring
using this procedure to establish compliance with the permit condition. The tests will be performed during the
months of January, April, July and October. Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.

Subject: NPDES Permit Issuance
Permit No. NC0086160
Midland Fiber Facility
Cabarrus County
In accordance with the application for discharge permit received on July 7, 1997, the Division is forwarding
herewith the subject state - NPDES permit. This permit is issued pursuant to the requirements of North Carolina
General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental
Protection Agency dated December 6, 1983.
In response to your comments regarding the draft NPDES permit received September 19, 1997, the
Division offers the following:
• The permit cover sheet has been modified to accurately reflect the tributaries into which outfalls 001
and 002 discharge.
• The supplement to permit cover page and the effluent limitations page for outfall 003 have been
modified to reflect a 0.0274 MGD monthly average flow limitation.
A compliance schedule has been installed in this permit to reflect the temporary discharge of non -contact
cooling water and boiler blowdown through outfalls 001 and 002 respectively. Beginning on July 1, 1998, all
wastewaters other than stormwater should be routed to, and subsequently discharge from, outfall 003. Should
Coming's schedule for the diversion of non -contact cooling water and boiler blowdown to outfall 003 change, the
Division must be contacted immediately.
Because of the hydraulic nature of the receiving stream, the Division recommended against the installation
of an effluent diffuser. In light of this fact, and the potential for this discharge to effect the instream biological
community, a benthic macroinvertebrate survey condition has been installed as condition A (8) of the supplement to
effluent limitations and monitoring portion of the permit.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to
you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of
this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North
Carolina General Statutes, and filed with the office of Administrative Hearings, Post Office Drawer 27447, Raleigh,
North Carolina 27611-7447. Unless such a demand is made, this permit shall be final and binding.

Please take notice that this permit is not transferable. Part II, E.4. addresses the requirements to be
followed in case of change in ownership or control of this discharge.
This permit does not affect the legal requirements to obtain other permits which may be required by the
Division of Water Quality or permits required by the Division of Land Resources, Coastal Area Management Act, or
any other Federal or Local governmental permits may be required.
If you have any questions or need additional information, please contact Mr. Mark McIntire, telephone

PART II
STORMWATER MONITORING, CONTROLS AND LIMITATIONS FOR PERMITTED DISCHARGES
SECTION A: FINAL LIMITATIONS AND CONTROLS FOR STORMWATER DISCHARGES
During the period beginning on the effective date of the permit and lasting until expiration, the permittee is
authorized to discharge stormwater associated with industrial activity from outfalls 001 and 002. Such discharges
shall be controlled, limited and monitored as specified below.
Stormwater Pollution Prevention Plans
The permittee shall develop and continue to update a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. The Plan shall be considered public information in accordance with Part III, Standard Conditions, Section
E.10. of this permit. The Plan shall include, at a minimum, the following items:
a. Site Plan: The site plan shall provide a description of the physical facility and the potential pollutant sources
which may be expected to contribute to contamination of regulated stormwater discharges. The site plan
shall contain the following:
(1) A general location map (USGS quadrangle map, or appropriately drafted equivalent map), showing
the facility's location in relation to transportation routes and surface waters, and the name of the
receiving water(s) to which the stormwater outfall(s) discharges. If the discharge is to a municipal
separate storm sewer system, the name of the municipality and the ultimate receiving waters, and
accurate latitude and longitude of the point(s) of discharge must be shown.
(2) A narrative description of storage practices, loading and unloading activities, outdoor process areas,
dust or particulate generating or control processes, and waste disposal practices.
(3) A site map (or series of maps) drawn to scale with the distance legend indicating location of
industrial activities (including storage of materials, disposal areas, process areas, and loading and
unloading areas), drainage structures, drainage areas for each outfall and activities occurring in the
drainage area, building locations and impervious surfaces, the percentage of each drainage area that
is impervious. For each outfall, a narrative description of the potential pollutants which could be
expected to be present in the regulated stormwater discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility during the 3
previous years and any corrective actions taken to mitigate spill impacts.
(5) Certification that the stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. The certification statement will be signed in accordance with the requirements found in
Part III, Standard Conditions, Section B.11.
Stormwater Management Plan: The stormwater management plan shall contain a narrative description of the
materials management practices employed which control or minimize the exposure of significant materials
to stormwater, including structural and non-structural measures. The stormwater management plan, at a
minimum, shall incorporate the following:
(1) A study addressing the technical and economic feasibility of changing the methods of operations
and/or storage practices to eliminate or reduce exposure of materials and processes to stormwater.
Wherever practicable the permittee should consider covering storage areas, material handling
operations, manufacturing or fueling operations to prevent materials exposure to stormwater. In
areas where elimination of exposure is not practicable, the stormwater management plan shall
document the feasibility of diverting the stormwater runoff away from areas of potential
contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials, storage of
Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water
priority chemicals, or storage of hazardous materials to prevent leaks and spills from contaminating

stormwater runoff. If the secondary containment devices are connected directly to stormwater
conveyance systems, the connection shall be controlled by manually activated valves or other
similar devices [which shall be secured with a locking mechanism] and any stormwater that
accumulates in the containment area shall be at a minimum visually observed prior to release of the

5. Mass/Day Measurements
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 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 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 IV
Page 2 of 14
6. Concentration Measurement
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 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.
The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. 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 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.
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.
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.

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.
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:
(1) 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 system, or
(3) a single, 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 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.

3. Need to Halt or Reduce not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary
to halt or reduce the permitted activity in order to maintain compliance with the condition of this
permit.
4. Bypassing of Treatment Facilities
a. Definitions
(1) "Bypass" means the known diversion of waste streams from any portion of a treatment
facility including the collection system, which is not a designed or established or operating
mode for the facility.
(2) "Severe property damage" means substantial physical damage to property, damage to the
treatment facilities which causes them to become inoperable, or substantial and permanent
loss of natural resources which can reasonably be expected to occur in the absence of a
bypass. Severe property damage does not mean economic loss caused by delays in
production.
b. Bypass not exceeding limitations.
The. permittee may allow any bypass to occur which does not cause effluent limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient operation. These
bypasses are not subject to the provisions of Paragraphs c. and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall
submit prior notice, if possible at least ten days before the date of the bypass; including an
evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
required in Part II, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against
a permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes or maintenance during normal periods of
equipment downtime. This condition is not satisfied if adequate backup equipment should
have been installed in the exercise of reasonable engineering judgment to prevent a bypass
which occurred during normal periods of equipment downtime or preventive maintenance;
and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.

Part IV
Page 9 of 14
5. Upsets
a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors beyond the
reasonable control of the permittee. An upset does not include noncompliance to the extent
caused by operational error, improperly designed treatment facilities, inadequate treatment
facilities, lack of preventive maintenance, or careless or improper operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with such
technology based permit effluent limitations if the requirements of paragraph 'c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
