the stormwater exposure of significant materials, including structural and nonstructural
measures. The Stormwater Management Strategy, at a minimum, shall incorporate the following:
a. `Feasibility Study. A review of 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 rainfall and run-on flows. Wherever practical, the permittee
shall prevent exposure of all storage areas, material handling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is not
practical,this review shall document the feasibility of diverting the stormwater run-on
away from areas of potential contamination.
b. Secondary Containment Requirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section 313 of
Title Ill of the Superfund Amendments and Reauthorization Act(SARA)water priority
chemicals; and storage in any amount of hazardous substances, in order to prevent leaks
and spills from contaminating stormwater runoff. A table or summary of all such tanks
and stored materials and their associated secondary containment areas shall be
maintained. If the secondary containment devices are connected to stormwater
conveyance systems, the connection shall be controlled by manually activated valves or
other similar devices (which shall be secured closed with a locking mechanism). Any
stormwater that accumulates in the containment area shall be at a minimum visually
observed for color, foam, outfall staining, visible sheens and dry weather flow,prior to
release of the accumulated stormwater. Accumulated stormwater shall be released if
found to be uncontaminated by any material. Records documenting the individual making
Page 12 of 19

DocuSign Envelope ID:AC4DA08E-93D4-4798-B32E-AF9EA578BA2E
Permit NC0086169
the observation, the description of the accumulated stormwater, and the date and time of
the release shall be kept for a period of five (5) years.
c. BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMPs) shall be provided. The installation and implementation of BMPs shall
be based on the assessment of the potential for sources to contribute significant quantities
of pollutants to stormwater discharges and on data collected through monitoring of
stormwater discharges. The BMP Summary shall include a written record of the specific
rationale for installation and implementation of the selected site BMPs. The BMP
Summary shall be reviewed and updated annually.
c) Spill Prevention and Response Procedures. The Spill Prevention and Response Procedures
(SPRP) shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel responsible for implementing the SPRP shall be
identified in a written list incorporated into the SPRP and signed and dated by each individual
acknowledging their responsibilities for the plan. A responsible person shall be on-site at all
times during facility operations that have the potential to contaminate stormwater runoff through
spills or exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, an oil Spill Prevention Control and Countermeasure plan(SPCC)
may be a component of the SPRP, but may not be sufficient to completely address the
stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may be
incorporated by reference into the SPRP.
d) Preventative Maintenance and Good Housekeeping Program. A preventative maintenance
and good housekeeping program shall be developed and implemented. The program shall
address all stormwater control systems (if applicable), stormwater discharge outfalls, all on-site
and adjacent surface waters and wetlands, industrial activity areas (including material storage
areas, material handling areas, disposal areas,process areas, loading and unloading areas, and
haul roads), all drainage features and structures, and existing structural BMPs. The program shall
establish schedules of inspections, maintenance, and housekeeping activities of stormwater
control systems, as well as facility equipment, facility areas, and facility systems that present a
potential for stormwater exposure or stormwater pollution where not already addressed under
another element of the SPPP. Inspection of material handling areas and regular cleaning
schedules of these areas shall be incorporated into the program. Timely compliance with the
established schedules for inspections, maintenance, and housekeeping shall be recorded and
maintained in the SPPP.
e) Facility Inspections. Inspections of the facility and all stormwater systems shall occur as part of
the Preventative Maintenance and Good Housekeeping Program at a minimum on a semi-annual
schedule, once during the first half of the year(January to June), and once during the second half
(July to December), with at least 60 days separating inspection dates (unless performed more
frequently than semi-annually). These facility inspections are different from, and in addition to,
the stormwater discharge characteristic monitoring at the outfalls required in Part A. (7.)(2.) of
this Section (Qualitative Monitoring).
f) Employee Training. Training programs shall be developed and training provided at a minimum
on an annual basis for facility personnel with responsibilities for: spill response and cleanup,
preventative maintenance activities, and for any of the facility's operations that have the potential
Page 13 of 19

DocuSign Envelope ID:AC4DA08E-93D4-4798-B32E-AF9EA578BA2E
Permit NC0086169
to contaminate stormwater runoff. The facility personnel responsible for implementing the
training shall be identified, and their annual training shall be documented by the signature of
each employee trained.
g) Responsible Party. The SPPP shall identify a specific position or positions responsible for the
overall coordination, development, implementation, and revision of the SPPP. Responsibilities
for all components of the SPPP shall be documented and position assignments provided.
h) SPPP Amendment and Annual Update. The permittee shall amend the SPPP whenever there is
a change in design, construction, operation, site drainage, maintenance, or configuration of the
physical features which may have a significant effect on the potential for the discharge of
pollutants to surface waters. All aspects of the SPPP shall be reviewed and updated on an
annual basis. The annual update shall include:
a. an updated list of significant spills or leaks of pollutants for the previous three (3) years,
or the notation that no spills have occurred(element of the Site Overview);
b. a written re-certification that the stormwater outfalls have been evaluated for the
presence of non-stormwater discharges (element of the Site Overview);
c. a documented re-evaluation of the effectiveness of the on-site stormwater BMPs (BMP
Summary element of the Stormwater Management Strategy).
d. a review and comparison of sample analytical data to benchmark values (if applicable)
over the past year, including a discussion about Tiered Response status. The permittee
shall use the Annual Summary Data Monitoring Report (DMR) form, available from the
Stormwater Permitting Program's website (See `Monitoring Forms' here:
https://deq.nc.gov/about/divisions/energy-mineral-land-resources/npdes-industrial-
stormwater).
i) The Director may notify the permittee when the SPPP does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall submit a
time schedule to the Director for modifying the SPPP to meet minimum requirements. The
permittee shall provide certification in writing (in accordance with Part II, Section B.11.) to the
Director that the changes have been made.
j) SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention
Plan and all appropriate BMPs to prevent contaminants from entering surface waters via
stormwater. Implementation of the SPPP shall include documentation of all monitoring,
measurements, inspections, maintenance activities, and training provided to employees,
including the log of the sampling data and of actions taken to implement BMPs associated with
the industrial activities, including vehicle maintenance activities. Such documentation shall be
kept on-site for a period of five (5) years and made available to the Director or the Director's
authorized representative immediately upon request.
2. Qualitative Monitoring Requirements
Qualitative 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(SPPP) and assessing new sources of stormwater pollution. No analytical
tests are required. Qualitative monitoring of stormwater outfalls must be performed semi-annually
Page 14 of 19

DocuSign Envelope ID:AC4DA08E-93D4-4798-B32E-AF9EA578BA2E
Permit NC0086169
during a measurable storm event (unless the permittee is required to perform further qualitative
sampling per the Qualitative Monitoring Response,below).
A measurable storm event is a storm event that results in an actual discharge from the permitted
site outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-
hour storm interval does not apply if the permittee is able to document that a shorter interval is
representative for local storm events during the sampling period, and the permittee obtains approval
from the local Regional Supervisor(See Part V., Definitions).
Inability to sample because of adverse weather conditions must be documented in the SPPP and
recorded on the DMR (see Adverse Weather in Part V., Definitions). Only SDOs discharging
stormwater associated with industrial activity must be monitored(see Part V., Definitions).
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall
document the suspected cause of the condition and any actions taken in response to the discovery.
This documentation will be maintained with the SPPP.

1. Frequency: The first qualitative observation during the term of the permit must be
performed within the first six months of the permit term and during the initial analytical
monitoring event(applicable to outfall 002). All subsequent qualitative monitoring will
be performed twice per year(spaced at least 60 days apart) during a measureable
storm event.
2. Monitoring Type: Monitoring requires a qualitative observation of each stormwater
outfall. No analytical testing or sampling is required.
3. SDO: effluent at outfalls 001 and 002.
A minimum of 60 days must separate monitoring events, unless additional sampling has been
instituted as part of the Qualitative Monitoring Response below.
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are ineffective, or
that significant stormwater contamination is present, the permittee shall investigate potential causes,
evaluate the feasibility of corrective actions, and implement those corrective actions within 60 days,
per the Qualitative Monitoring Response that follows. A written record of the permittee's
investigation, evaluation, and response actions shall be kept in the Stormwater Pollution Prevention
Plan.

Permit NC0086169
• ° qualitative Monitoring Response
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, assessing new sources
of stormwater pollution, and prompting the permittee's response to pollution. If the permittee
repeatedly fails to respond effectively to correct problems identified by qualitative monitoring, or
if the discharge causes or contributes to a water quality standard violation, DWR may but is not
limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency
(analytical or qualitative) for the remainder of the permit;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure
Exclusion.
A. (8) ANNUAL SHUTDOWN PROCEDURES CONDITION
[G.S. 143-215.1(b)]
On an annual basis, the permittee is permitted to discharge up to 250,000 gallons of non-contact cooling
water and flush water, from the two cooling tower basins, through Outfall 002. The semi-annual
monitoring associated with Outfall 002 shall coincide with this event. Corning Incorporated shall
develop a HVAC Cooling Tower Shutdown Procedure consistent with Betz-Dearborn recommendations.
The HVAC Cooling Tower Shutdown Procedure should include the condition that both cooling towers
will not be flushed at the same time. This procedure shall be kept on site and available for review by
Division staff upon request. Additionally, the time and duration for the discharge of non-contact cooling
water through Outfall 002 shall be recorded in the operations log by the Operator in Responsible Charge.
and available for review by the Division upon request.
A. (9) BIOCIDES
[G.S. 143-215, 143-215.1]
The permittee shall not discharge any biocides except those approved in conjunction with the permit
application. Prior to September 1, 2019, the permittee shall not discharge any additional biocide used in
cooling systems which may be toxic to aquatic life other than those previously reported to the Division
of Water Resources. Such notification shall include completion of Biocide Worksheet Form 101 and a
map locating the discharge point and receiving stream. Completion of Biocide Worksheet Form 101 is
not necessary for those outfalls containing toxicity testing. Division approval is not necessary for the
introduction of new biocides into outfalls currently tested for whole effluent toxicity.
After September 1, 2019, the permittee shall not use any biocides except those approved in conjunction
with the permit application. The permittee shall notify the Director in writing not later than ninety(90)
days prior to instituting use of any additional biocide used in cooling systems which may be toxic to

permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report(eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring
data and submit DMRs electronically using the internet. Until such time that the state's eDMR
application is compliant with EPA's Cross-Media Electronic Reporting Regulation(CROMERR),
permittees will be required to submit all discharge monitoring data to the state electronically using
eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one
signed original and a copy of the computer printed eDMR to the following address:
NC DEQ/Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility
being physically located in an area where less than 10 percent of the households have broadband access,
then a temporary waiver from the NPDES electronic reporting requirements may be granted and
discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3) or alternative forms
approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. See
"How to Request a Waiver from Electronic Reporting" section below.

Regardless of the submission method, the first DMR is due on the last day of the month following the
issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
Starting on December 21, 2020, the permittee must electronically report the following compliance
monitoring data and reports,when applicable:
• Sewer Overflow/Bypass Event Reports;
• Pretreatment Program Annual Reports; and
• Clean Water Act(CWA) Section 316(b)Annual Reports.
The permittee may seek an electronic reporting waiver from the Division(see "How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time of
each electronic submission. The permittee should use the EPA's website resources to identify the initial
recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity for
receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each
type of electronic submission and for each state. Instructions on how to access and use the appropriate
electronic reporting tool will be available as well. Information on EPA's NPDES Electronic Reporting
Rule is found at: https://www.federalregister.gov/documents/2015/10/22/2015-24954/national-pollutant-
discharge-elimination-system-npdes-electronic-reporting-rule.
Electronic submissions must start by the dates listed in the"Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the
Division. Requests for temporary electronic reporting waivers must be submitted in writing to the
Division for written approval at least sixty(60) days prior to the date the facility would be required
under this permit to begin submitting monitoring data and reports. The duration of a temporary waiver
shall not exceed 5 years and shall thereupon expire. At such time,monitoring data and reports shall be
submitted electronically to the Division unless the permittee re-applies for and is granted a new
temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not
transferrable. Only permittees with an approved reporting waiver request may submit monitoring data
and reports on paper to the Division for the period that the approved reporting waiver request is
effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on the
following web page:

NPDES STORMWATER PERMITS
Section A. Definitions
Adverse Weather Conditions
Adverse conditions are those that are dangerous or create inaccessibility for personnel,such as local flooding,high
winds,or electrical storms, or situations that otherwise make sampling impractical. When adverse weather
conditions prevent the collection of samples during the sample period,the permittee must take a substitute sample
or perform a visual assessment during the next qualifying storm event.Documentation of an adverse event(with
date,time and written narrative) and the rationale must be included with your SPPP records. Adverse weather
does not exempt the permittee from having to file a monitoring report in accordance with the sampling schedule.
Adverse events and failures to monitor must also be explained and reported on the relevant DMR.
Allowable Non-Stormwater Discharges
This permit regulates stormwater discharges. Non-stormwater discharges which shall be allowed in the
stormwater conveyance system are:
(a) All other discharges that are authorized by a non-stormwater NPDES permit.

A. (4.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY TEST AT 0.107 MGD)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 1.0%.
The permit holder shall perform at a minimum, quarterlq monitoring using test procedures outlined in 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, 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.
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.

Permit NC0086169
A. (7.) STORMWATER MONITORING, CONTROLS AND LIMITATIONS FOR PERMITTED DISCHARGES
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.
1. Stormwater Pollution Prevention Plans
The permittee shall develop and implement a Stormwater Pollution Prevention Plan (SPPP). The SPPP shall be
maintained on site unless exempted from this requirement by the Division. The SPPP is public information in accordance
with Part IV,Section B.8.of this permit. The SPPP shall include,at a minimum,the following items:
a) 'Site Overview. The Site Overview shall provide a description of the physical facility and the potential pollutant
sources that may be expected to contribute to contamination of stormwater discharges. The Site Overview shall
contain the following:
a. 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;the name of the receiving waters to
which the stormwater outfalls discharge, or 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
points of stormwater discharge associated with industrial activity. The general location map (or
alternatively the site map)shall identify whether any receiving waters are impaired(on the state's 303(d)list
of impaired waters) or if the site is located in a watershed for which a TMDL has been established, and
what the parameters of concern are.
b. A narrative description of storage practices,loading and unloading activities,outdoor process areas,dust or
particulate generating or control processes, and waste disposal practices. A narrative description of the
potential pollutants that could be expected to be present in the stormwater discharge from each outfall.
c. A site map drawn at a scale sufficient to clearly depict: the site property boundary; the stormwater
discharge outfalls;all on-site and adjacent surface waters and wetlands;industrial activity areas (including
storage of materials, disposal areas, process areas, loading and unloading areas, and haul roads); site
topography and finished grade; all drainage features and structures; drainage area boundaries and total
contributing area for each outfall; direction of flow in each drainage area;industrial activities occurring in
each drainage area; buildings; stormwater Best Management Practices (BMPs); and impervious surfaces.
The site map must indicate the percentage of each drainage area that is impervious,and the site map must
include a graphic scale indication and north arrow.
d. A list of significant spills or leaks of pollutants during the previous three (3) years and any corrective
actions taken to mitigate spill impacts.
e. Certification that the stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. The permittee shall re-certify annually 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,Section B.11.
b) Stormwater Management Strategy. The Stormwater Management Strategy shall contain a narrative description of
the materials management practices employed which control or minimize the stormwater exposure of significant
materials, including structural and nonstructural measures. The Stormwater Management Strategy,at a minimum,
shall incorporate the followinng:
a. Feasibility Study. A review of 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 rainfall and run-on
flows. Wherever practical, the permittee shall prevent exposure of all storage areas, material handling
operations, and manufacturing or fueling operations. In areas where elimination of exposure is not
Page 9 of 15

Permit NC0086169
practical,this review shall document the feasibility of diverting the stormwater run-on away from areas of
• potential contamination.
b. Secondary Containment Requirements and Records. Secondary containment is required for: bulk storage
of liquid materials; storage in any amount of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act(SARA) water priority chemicals;and storage in any amount of hazardous substances,
in order to prevent leaks and spills from contaminating stormwater runoff. A table or summary of all such
tanks and stored materials and their associated secondary containment areas shall be maintained. If the
secondary containment devices are connected to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices (which shall be secured closed with a
locking mechanism). Any stormwater that accumulates in the containment area shall be at a minimum
visually observed for color,foam, outfall staining,visible sheens and dry weather flow, prior to release of
the accumulated stormwater. Accumulated stormwater shall be released if found to be uncontaminated by
any material. 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(5)years.
• c. BMP Summary. A listing of site structural and non-structural Best Management Practices (BMPs)shall be
provided. The installation and implementation of BMPs shall be based on the assessment of the potential
for sources to contribute significant quantities of pollutants to stormwater discharges and on data collected
through monitoring of stormwater discharges. The BMP Summary shall include a written record of the
specific rationale for installation and implementation of the selected site BMPs. The BMP Summary shall be
reviewed and updated annually.
c) Spill Prevention and Response Procedures. The Spill Prevention and Response Procedures(SPRP)shall incorporate
an assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel
responsible for implementing the SPRP shall be identified in a written list incorporated into the SPRP and signed and
dated by each individual acknowledging their responsibilities for the plan. A responsible person shall be on-site at
all times during facility operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site stormwater specific. Therefore, •
an oil Spill Prevention Control and Countermeasure plan(SPCC) may be a component of the SPRP,but may not be
sufficient to completely address the stormwater aspects of the SPRP. The common elements of the SPCC with the
SPRP may be incorporated by reference into the SPRP.
d) Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and good housekeeping
program shall be developed and implemented. The program shall address all stormwater control systems (if
applicable), stormwater discharge outfalls, all on-site and adjacent surface waters and wetlands, industrial activity
areas(including material storage areas,material handling areas,disposal areas,process areas,loading and unloading
areas, and haul roads), all drainage features and structures, and existing structural BMPs. The program shall
establish schedules of inspections,maintenance, and housekeeping activities of stormwater control systems,as well
as facility equipment, facility areas, and facility systems that present a potential for stormwater exposure or
stormwater pollution where not already addressed under another element of the SPPP. Inspection of material
handling areas and regular cleaning schedules of these areas shall be incorporated into the program. Timely
compliance with the established schedules for inspections, maintenance, and housekeeping shall be recorded and
maintained in the SPPP.
e) Facility Inspections. Inspections of the facility and all stormwater systems shall occur as part of the Preventative
Maintenance and Good Housekeeping Program at a minimum on a semi-annual schedule, once during the first half
of the year (January to June),and once during the second half(July to December), with at least 60 days separating
inspection dates (unless performed more frequently than semi-annually). These facility inspections are different
from, and in addition to,the stormwater discharge characteristic monitoring at the outfalls required in Part A. (7.)(2.)
of this Section(Qualitative Monitoring).
•

Permit NC0086169
f) Employee Training. Training programs shall be developed and training provided at a minimum on an annual basis
for facility personnel with responsibilities for: spill response and cleanup,preventative maintenance activities,and
for any of the facility's operations that have the potential to contaminate stormwater runoff. The facility personnel
responsible for implementing the training shall be identified,and their annual training shall be documented by the
signature of each employee trained.
g) Responsible Party. The SPPP shall identify a specific position or positions responsible for the overall coordination,
development, implementation, and revision of the SPPP. Responsibilities for all components of the SPPP shall be
documented and position assignments provided.
h) SPPP Amendment and Annual Update. The permittee shall amend the SPPP whenever there is a change in design,
construction, operation, site drainage, maintenance, or configuration of the physical features which may have a
significant effect on the potential for the discharge of pollutants to surface waters. All aspects of the SPPP shall be
reviewed and updated on an annual basis.The annual update shall include:
a. an updated list of significant spills or leaks of pollutants for the previous three(3)years,or the notation that no
spills have occurred(element of the Site Overview);
b. a written re-certification that the stormwater outfalls have been evaluated for the presence of non-stormwater
discharges(element of the Site Overview);
c. a documented re-evaluation of the effectiveness of the on-site stormwater BMPs (BMP Summary element of
the Stormwater Management Strategy).
d. a review and comparison of sample analytical data to benchmark values (if applicable) over the past year,
including a discussion about Tiered Response status. The permittee shall use the Annual Summary Data
Monitoring Report (DMR) form, available from the Stormwater Permitting Programs website (See
'Monitoring Forms'here: http://portal.ncdenr.org/web/hr/npdes-stormwater).
i) The Director may notify the permittee when the SPPP does not meet one or more of the minimum requirements of
the permit. Within 3Q days of such notice,the permittee shall submit a time schedule to the Director for modifying
the SPPP to meet minimum requirements. The permittee shall provide certification in writing (in accordance with
Part II,Section B.11.)to the Director that the changes have been made.
j) .SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention Plan and all appropriate
BMPs to prevent contaminants from entering surface waters via stormwater. Implementation of.the SPPP shall
include documentation of all monitoring, measurements,inspections,maintenance activities,and training provided
to employees, including the log of the sampling data and of actions taken to implement BMPs associated with the
industrial activities,including vehicle maintenance activities. Such documentation shall be kept on-site for a period
of five (5) years and made available to the Director or the Director's authorized representative immediately upon
request.

Permit NC0086169 . .
2. Qualitative Monitoring Requirements
Qualitative 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 (SPPP) and assessing new sources of stormwater pollution. No analytical tests are required.
Qualitative monitoring of stormwater outfalls must be performed semi-annually during a measurable storm
event (unless the permittee is required to perform further qualitative sampling per the Qualitative
Monitoring Response, below).
Inability to sample because of adverse weather conditions must be documented in the SPPP and recorded on
the DMR (see Adverse Weather in Part V., Definitions). Only SDOs discharging stormwater associated with
industrial activity must be monitored (see Part V., Definitions).
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall document the
suspected cause of the condition and any actions taken in response to the discovery. This documentation will
be maintained with the SPPP.

event (applicable to outfall 002). All subsequent qualitative monitoring will be performed •
twice per year(spaced at least 60 days apart) during a measureable storm event.
2 Monitoring Type: Monitoring requires a qualitative observation of each stormwater outfall. No
analytical testing or sampling is required.
3 SDO: effluent at outfalls 001 and 002.
A minimum of 60 days must separate monitoring events, unless additional sampling has been instituted as
part of the Qualitative Monitoring Response below.
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are ineffective, or that
significant stormwater contamination is present, the permittee shall investigate potential causes, evaluate the
feasibility of corrective actions, and implement those corrective actions within 60 days, per the Qualitative
Monitoring Response that follows. A written record of the permittee's investigation, evaluation, and
response actions shall be kept in the Stormwater Pollution Prevention Plan.
Page 12 of 15

Permit NC0086169
Qualitative Monitoring Response •
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, assessing new sources of
stormwater pollution, and prompting the permittee's response to pollution. If the permittee repeatedly
fails to respond effectively to correct problems identified by qualitative monitoring, or if the discharge
causes or contributes to a water quality standard violation,DWR may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency (analytical or
qualitative)for the remainder of the permit;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize impacts
on receiving waters;or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.

A. (8.) ANNUAL SHUTDOWN PROCEDURES CONDITION
On an annual basis, the permittee is permitted to discharge up to 250,000 gallons of non-contact cooling water
and flush water, from the two cooling tower basins, through Outfall 002. The semi-annual monitoring associated
with outfall 002 shall coincide with this event. Corning Incorporated shall develop a HVAC Cooling Tower
Shutdown Procedure consistent with Betz-Dearborn recommendations. The HVAC Cooling Tower Shutdown
Procedure should include the condition that both cooling towers will not be flushed at the same time. This
procedure shall be kept on site and available for review by Division staff upon request. Additionally, the time and
duration for the discharge of non-contact cooling water through outfall 002 shall be recorded in the operations log
by the Operator in Responsible Charge and available for review by the Division upon request.
A. (9.) ELECTRONIC REPORTING Of DISCHARGE MONITORING REPORTS
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and specify
that, if a state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the Environmental Protection Agency(EPA). The Division anticipates that these regulations will
be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this permit
(Standard Conditions for NPDES Permits): •
• Section B. (11.) Signatory Requirements

ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being
physically located in an area where less than 10 percent of the households have broadband access, then a
temporary waiver from the NPDES electronic reporting requirements may be granted and discharge
monitoring data may be submitted on paper DMR forms (MR 1, 1.1, 2, 3) or alternative forms approved by the
Director. Duplicate signed copies shall be submitted to the mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be submitted in
writing to the Division for written approval at least sixty(60) days prior to the date the facility would be
required under this permit to begin using eDMR. Temporary waivers shall be valid for twelve (12) months and
shall thereupon expire. At such time, DMRs shall be submitted electronically to the Division unless the
permittee re-applies for and is granted a new temporary waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http://portal.ncdenr.org/web/wq/admin/bog/ipu/edmr
Page 14 of 15

Permit NC0086169
Regardless of the submission method, the first DMR is due on the last day of the month following the
issuance of the permit or in the case of a new facility, on the last day of the month following the
commencement of discharge.
2. Signatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B. (11.) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section

monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass,the"daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement,the
"daily discharge"is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2;see also
"Composite Sample,"above.)
Daily Maximum
The highest"daily discharge"during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s),that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).

Interference
Inhibition or disruption of the POTW treatment processes; operations;or its sludge process,use,or disposal which
causes or contributes to a violation of any requirement of the Permittee's(or any satellite POTW's if different from the
Permittee)NPDES, collection system,or non-discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes,regulations,or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources,causes a violation,including an increase in the magnitude or duration of a violation,of
the Permittee's(or any satellite POTW's,if different from the Permittee)NPDES,collection system, or non-discharge
permit. [15A NCAC 02H.0903(b)(23)]
Publicly Owned Treatment Works(POTW)
A treatment works as defined by Section 212 of the CWA,which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage,treatment,recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature.It also includes the collection system,as defmed in 15A NCAC 2T
.0402,only if it conveys wastewater to a POTW treatment plant.The term also means the local government
organization,or municipality,as defmed in section 502(4)of the CWA,which has jurisdiction over indirect discharges
to and the discharges from such a treatment works.In this context,the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges.This second type of
POTW may be referred to as a"satellite POTW organization." [15A NCAC 02H.0903(b)(26)]
"Significant Industrial User" or"SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that[15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW(excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non-discharge permitted
flow limit or organic capacity of the POTW treatment plant.In this context,organic capacity refers to BOD,TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement,or the POTW's effluent
limitations and conditions in its NPDES or non-discharge permit,or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b),the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this defmition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement,the POTW's effluent limitations and
conditions in its NPDES or non-discharge permit,or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User(SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b),the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2)and thus is a
non-significant categorical Industrial User.
Section B. Publicly Owned Treatment Works(POTWs)
Version 11/09/2011

• NPDES Permit Standard Conditions
Page 15 of 18
All POTWs must provide adequate notice to the Director of the following[40 CFR 122.42(b)]:

from the scrubbers, water softuer from floors drain, water softner blowdown, and cooling tower
blowdown. Outfall 001 consists of stormwater only. Outfall 002 consists of stormwater,
cooling tower and boiler blowdown.
In item No. 12 of the renewal application,the permittee listed the number of discharges
that do not actually discharge to surface water. The only discharge to surface water is the process
wastewater. The sanitary sewer discharges to Muddy Creek WWTP, and most of the utility
water will evaporate in the detention basin prior to being discharged.
There has been no changes in the operation since 2008, and the permittee wishes to renew
the permit for the discharge of 0.017 MGD. There has been no expansion since the last renewal.
Pending review and approval by the NPDES Unit, It is recommended that the NPDES

one being considered at this time.
•
4. Alternative analysis evaluation: There is no known alternative other than a discharge to
surface waters at this time. All non-discharge alternatives available to this facility were
evaluated prior to this plant being built, and this Office is unaware of any of changes in the
status of these alternative at this time. Corning discharges all domestic wastewater into the
Water and Sewer Authority of Cabarrus County's Muddy Creek WWTP, however, there is
insufficient capacity at the Muddy Creek WWTP to accept all of Coming's waste streams.
PART IV- EVALUATION AND RECOMMENDATIONS
Corning, Inc. requests the reissuance of an NPDES Permit for the discharge of both process
water and non-contact cooling water from a facility located southern Cabarrus County. The Corning
facility began limited operation again in in the fall of 2007 after being closed (mothballed) for
nearly 5 years due to poor economic conditions.
The process water discharge (outfall 003) contains the following sources of wastewater:
1. Blowdown from pollution abatement equipment. -kAt Sc.,,,,igr..,-
2. Water softener from area floor drains.
3. Water softener blowdown.
4. Cooling tower blowdown.
5. Some stormwater.
The two (2) cooling water outfalls (001 & 002) leave the site only after passing through a
wet detention basin. During periods of infrequent rainfall these basins may hold little, if any water.
However, during wet-weather,these basins may hold substantial quantities of water, which will be
made up primarily of stormwater. Most of the site's stormwater has been channeled around the
detention basins, however, there will still be a considerable quantity of that enters the basins either
directly or indirectly.
Pending receipt and approval of the draft permit, it is recommended that the NPDES Permit
be reissued as requested.

Dear Ms. Sprinkle,
Please fmd the enclosed NPDES permit renewal application for the Coming Incorporated,Optical
Fiber Facility, in Midland,NC,Cabarrus County. One signed and two copies are enclosed.
Note that this facility had been in a mothball status for nearly 5 years(no production). The NPDES
permit was maintained in an active state. In the fall of 2007,the facility began limited operations.
As such,some data in the application is from a limited data set,and some is historical information.
At this time,flow is intermittent and water samples are taken when water flow is available.
Production may or may not continue to ramp. Business conditions will dictate the level of
production.
Please note that there is Confidential Business Information enclosed. We are requesting that this
information be treated as such, since this information has competitive value.
Please contact Rodney Morgan at(704)569-7209 if there are any questions.

originally received its National Pollutant Discharge Elimination System (NPDES) permit in 1998. Startup
- began late that, year. The facility:was issued a renewed NPDES permit on March 31', 2004, which -
• included an expanded flow to 0.142 MGD for the outfall 003.
Wastewater generated includes sanitary wastewater, non-contact cooling wastewater,process wastewater, .
stormwater, filter backwash water and boiler blowdown. Currently, sanitary wastewater is treated off-site
at the Muddy Creek Wastewater Treatment Plant. Wastewaters other than.sanitary.are treated and .
• discharge through one of three outfalls as summarized below. -
- • Outfall 001
This discharge is comprised of 100% stormwater, collected in a stormwater retention pond. The receiving
- stream is an unnamed tributary of Muddy Creek. Currently, no effluent limitations and monitoring page.
is contained within the permit for this outfall, though stormwater controls are required. Part I, Section A, -

This discharge is comprised of industrial process wastewater, non-contact cooling water, and carbon filter
backwash water. These wastewaters are neutralized and treated using a solids removal unit prior
discharge into the Rocky River.
TOXICITY TESTING:
Current Requirement: Chronic P/F @ 1.0%at 0.107 MGD using Ceriodaphnia
Proposed Requirement: Chronic P/F @ 1.7%at 0.142 MGD using Ceriodaphnia
The above IWCs were calculated using a flow equal to the sum of the permitted flow at outfall 003 and the
non-contact cooling water contribution.
This facility has passed all toxicity tests since startup.
COMPLIANCE SUMMARY:
The facility has been in compliance with its NPDES Permit.
INSTREAM MONITORING:
A benthic macroinvertebrate study was required in the original permit. That permit required the facility to
complete a benthic survey during.the summer of 1999. The study was completed in August and
submitted to the Division for review. Dave Lenat of the Environmental Sciences Branch reviewed the
study and provided the writer with comments. His conclusions were in agreement with the study results,
which indicated no biological impact from this discharge. As the discharge will be expanding, the benthic
survey requirement will be included with this renewal, and' should be completed upon completion of
expansion, should such expansion take place.

Dear Mr. Hannan:
•
Our records indicate that NPDES Permit No.NC0086169 was issued on March 31, 2004 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, 5 and 6.
Pages 4, 5 and 6 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 (DWQ 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 be1 paid in a timely manner so as to prevent enforcement action or possible 21

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 requirements for a certified wastewater treatment plant
operator if you are operating wastewater treatment 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.

4. CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY TEST AT 0.107 MGD)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 1.0%.
The permit holder shall perform at a minimum, quarterlq monitoring using test procedures outlined in 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, 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.
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 TGP3B for the
pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:

concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature.
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 the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be
required during the following month.
Should any test data from this monitoring requirement 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, minimum control organism reproduction, 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.

-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
(i) 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).

(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.
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.

NC0086169

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
(I) 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 extractable 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").
7. BIOLOGICAL MONITORING CONDITION
After completion of the expansion to 0.142 MGD, the Permittee shall conduct an upstream and downstream
benthic macroinvertebrate survey. This survey should be conducted between the months of June and September.
A report of the survey's findings shall be included with the next permit renewal application after the expansion is
completed.

Unit at [phone].
8. STORMWATER MONITORING, CONTROLS AND LIMITATIONS FOR PERMITTED DISCHARGES
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.
1. 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:

„ NC0086169
L'
(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.
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

THIS FACILITY HAS BEEN MOTHBALLED. AS SUCH, THIS PERMIT RENEWAL IS A
SIMPLE ROLLOVER OF THE PREVIOUSLY ISSUED PERMIT AND ALL SUBSEQUENTLY
ISSUED MODIFICATIONS.
SUMMARY OF FACILITY AND WASTELOAD ALLOCATION
Corning Incorporated manufactures optical fibers at its Midland facility in Cabarrus County. The facility
originally received its National Pollutant Discharge Elimination System (NPDES) permit in 1998. Startup
began late that year. The facility was issued a renewed NPDES permit on April 14, 2001, which included
an expanded flow to 0.107 MGD. On December 19, 2000, the Division of Water Quality received a
request for modification to the. NPDES Permit, specifically, the facility requested a flow expansion from
0.107 MGD to 0.142 MGD.
Wastewater generated includes sanitary wastewater, non-contact cooling wastewater, process wastewater,
stormwater, filter backwash water and boiler blowdown. Currently, sanitary wastewater is treated off-site
at the Muddy Creek Wastewater Treatment Plant. Wastewaters other than sanitary are treated and
discharge through one of three outfalls as summarized below.
Outfall 001
This discharge is comprised of 100% stormwater, collected in a stormwater retention pond. The receiving
stream is an unnamed tributary of Muddy Creek. Currently, no effluent limitations and monitoring page
is contained within the permit for this outfall, though stormwater controls are required. Part I, Section A,
Number 8 of the permit addresses stormwater discharges and applicable monitoring requirements.
Outfall 002
This discharge is comprised of stormwater, non-contact cooling water, and humidification boiler
blowdown. Wastewater is collected in a wet detention pond prior to discharge into an unnamed tributary
of Clear Creek. Effluent limitations and monitoring have been applied and stormwater controls are
required.
Outfall 003
This discharge is comprised of industrial process wastewater, non-contact cooling water, and carbon filter
backwash water. These wastewaters are neutralized and treated using a solids removal unit prior
discharge into the Rocky River.

TOXICITY TESTING:
Current Requirement: Chronic P/F @ 1.0% at 0.107 MGD using Ceriodaphnia
Proposed Requirement: Chronic P/F @ 1.7% at 0.142 MGD using Ceriodaphnia
The above IWCs were calculated using a flow equal to the sum of the permitted flow at outfall 003 and the
non-contact cooling water contribution.
This facility has passed all-toxicity tests since startup.
COMPLIANCE SUMMARY:
The facility has been in compliance with its NPDES Permit.
INSTREAM MONITORING:
A benthic macroinvertebrate study was required in the original permit. That permit required the facility to
complete a benthic survey during the summer of 1999. The study was completed in August and
submitted to the Division for review. Dave Lenat of the Environmental Sciences Branch-reviewed the
study and provided the writer with comments. His conclusions were in agreement with the study results,
which indicated no biological impact from this discharge. As the discharge will be expanding, the benthic
survey requirement will be included with this renewal, and should be completed upon completion of
expansion, should such expansion take place.

PART IV - EVALUATION AND RECOMMENDATIONS
Corning, Inc. requests the reissuance of an NPDES Permit for the discharge of both process
water and non-contact cooling water from a facility located southern Cabarrus County. The Corning
facility is currently closed (mothballed) as a result of poor economic conditions. There is no
timetable as to when the facility might reopen.
The process water discharge (outfall 003) contains the following sources of wastewater:
1. Blowdown from pollution abatement equipment.
2. Water softener from area floor drains.
3. Water softener blowdown.
4. Cooling tower blowdown.
5. Some stormwater.
The two (2) cooling water outfalls (001 & 002) leave the site only after passing through a
•
wet detention basin. During periods of infrequent rainfall these basins may hold little, if any water.
However, during wet-weather, these basins may hold substantial quantities of water, which will be
made up primarily of stormwater. Most of the site's stormwater has been channeled around the
detention basins, however, there will still be a considerable quantity of that enters the basins either
directly or indirectly.
Pending receipt and approval of the WLA, it is recommended that the NPDES Permit be
reissued as requested.

Subject: NPDES Permit Renewal Application
Permit NC0086169
Fiber Optic Facility
Cabarrus County
Dear Mr.Hannan:
The NPDES Unit received your permit renewal application on February 5, 2003. Thank you for submitting this
package.The renewal request did not include a sludge management plan. Please submit 3 copies of your
sludge management plan for this facility. The permit renewal cannot be completed
without this information.
The permit renewal for this facility will be assigned to Mark McIntire. This staff member will contact you if
further information is needed to complete the permit renewal. Please note that the NPDES Unit has several vacant
positions. This staff shortage has lasted for over 4 years and is delaying all permit renewals. Our remaining
permit writers are currently reviewing Authorizations to Construct, speculative limit requests, major permit
modifications and 201 plan updates ahead of permit renewals. This is necessary due to a variety of factors,
including mandatory deadlines in the statutes which govern our program.
If this staff shortage delays reissuance of NC0086169 the existing requirements in your permit will remain in
effect until the permit is renewed (or the Division takes other action). We appreciate your patience and
understanding while we operate with a severely depleted staff. If you have any additional questions concerning
renewal of the subject permit,please contact Mark McIntire at(919)733-5083, extension 508.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority: The Director of the Division of Water Quality.
2. DEM or"the Division" Means the Division of Water Quality,Department of Environment and Natural
Resources.
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 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.
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliforrn 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.

Part II
Page 2 of 11
6.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. 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.
f. The "quarterly average concentration" is the average of all samples taken over a calendar quarter. It is
identified as "Quarterly Average Limitation"in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods:January through March,April through
June,July through September,and October through December.
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

Part II
Page 3 of 11
8. a. (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.
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.

(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.

Part II
Page 7 of 11
4.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.
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 II,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.

generators or retention of inadequately treated effluent.
SECTION D. MONITORING AND RECORDS
1. Representative Sampling
Samples collected and measurements taken,as required herein, shall be characteristic of the volume and nature of
the permitted discharge. Samples collected at a frequency less than daily shall be taken on a day and time that is
characteristic of the discharge over the entire period which the sample represents. All samples shall be taken at
the monitoring points specified in this permit and, unless otherwise specified, before the effluent joins or is
diluted by any other wastestream, body of water, or substance. Monitoring points shall not be changed without
notification to and the approval of the Permit Issuing Authority.
2. Reporting
Monitoring results obtained during the previous month(s) shall be summarized for each month and reported on a
monthly Discharge Monitoring Report (DMR) Form (DEM No. MR 1, 1.1,2, 3) or alternative forms approved by
the Director,DEM,postmarked no later than the 30th day following the completed reporting period.
The first DMR is due on the last day of the month following the issuance of the permit or in the case of a new
facility, on the last day of the month following the commencement of discharge. Duplicate signed copies of
these,and all other reports required herein,shall be submitted to the following address:
NC DENR/Division of Water Quality/Water Quality Section
