Subject: RE: NPDES Stormwater Permit NCS000076
Hi Julie — please see comments/questions below regarding the revised SW permit:
1. The first question I mentioned to you on the phone earlier last week —the cover letter with changes states that
Outfalls 1 and 2 will no longer require analytical monitoring for all parameters. However, it is not listed in the
new permit.
In the current permit, it is noted on page 7 of 10 (Part Il Section B) in the table and in footnote #3.
To be clear, analytical monitoring is only required for Outfalls, 3, 4, 5, and 8 (which is represented by 3) and
qualitative monitoring is still required for all outfalis (Outfalls 1, 2, 3, 4, 5, & 8) —correct?
You are correct. It is our current practice to use standard language in our permits as much as possible. Rather
than revise your permit to reflect the Representative Outfall Status, we recommend you keep a copy of the original ROS
approval letter with the permit. I've also reiterated that approval in the attached cover letter.
2. Are Biological Integrity/D.O. no longer an issue?

Page 8 of 15 — Part Il Section B: Analytical Monitoring Requirements — shows mercury instead of Biological
Integrity /D.O. on the current permit — we just want to verify this is correct.
You are correct. I'm not certain why Biological Integrity/DO was included on your previous permit as it appears
this particular stream was never actually listed as impaired. My best guess is that other bodies of water
downstream of this receiving stream were impaired for DO, and the permit writer opted to include that
information.
3. Can you clarify the number of years of record retention for DMR & eDMR reports?
The new section for eDMRs shows 3 year retention for DMRs/eDMRs on page 14 of 15 -Section E: Special
Conditions, 4. Records Retention
However, the DMRs are still listed in the following two sections with a 5 year retention:
Page 4 of 15 — Part 11 Section A: SPPP, 9. SPPP Implementation — monitoring & measurements
Page 7 of 9 — Part III Section D: Monitoring & Records — 6. Records Retention — DMR reports
The number of years required for record retention will change on the date you start participating in electronic
reporting of DMR data. As I understand it, until you begin electronic reporting, the minimum retention time for DMRs is
5 years. After you begin electronic reporting, the minimum retention time for DMRs is 3 years (this is the federal
requirement). All other records that don't get reported electronically will have a minimum retention time of 5
years. Having said that, I'd suggest you keep all your records for 5 years as it might make it easier to summarize the
previous 5 years of data for purposes of renewing during your permit next cycle. I'm not sure if/when we will phase out
the 5-year retention requirement all together, but for now, we are kinda stuck with this staggered schedule.
4. Sampling periods
For the current permit, we are in the May 1— Oct 31 sampling period. The new permit is supposed to begin on
Sep 1 with the first sampling period as Sep 1— Dec 31.
If the start date of the new permit remains as Sept 1, our plan is to submit a final Stormwater report for the
current permit on Aug 31. Is that OK? Yes, that is fine.
S. Page 3 of 4 - Part IV #24—the numbering starts with W instead of 'a'. Thank you. I made this correction.
Feel free to call if questions —thanks!

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.
Such discharges shall be controlled, limited and monitored as specified in this permit.
If industrial materials and activities are not exposed to precipitation or runoff as described
in 40 CFR §122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES
stormwater discharge permit requirements. Any owner or operator wishing to obtain a No
Exposure Exclusion must submit a No Exposure Certification Notice of Intent (NOI) form to
Ar
the Division; must receive approval by the Division; must' �at� no exposure conditions
s unless authorized to discharge under a valid NPDES-�rmwaer permit; and must recertify
the No Exposure Exclusion annually.
SECTION B: PERMITTED ACTIVITIES

stormwater to the surface wa 6ft:of North,Carolina or separate storm sewer system that
has been adequately treated andfWainagMin accordance with the terms and conditions of
P- '
this permit. All stormwater dischargess shall be in accordance with the conditions of this
permit. I
Any other point source dis-clarge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization, or
approval. The stormwater discharges allowed by this permit shall not cause or contribute
to violations of Water Quality Standards.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
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 III, Standard
Conditions, Section E, paragraph 3 of this permit. The SPPP shall include, at a minimum,
the following items:
1. Site Overview. The Site Overview shall provide a des ion of the physical facility
and the potential pollutant sources that may bepA pe d contribute to
contamination of stormwater discharges. The Site-Wervievushall contain the following:
(a) A general location map (USGS quadranglesmap1-6nappropriate ly drafted equivalent
map), showing the facility's location in rem �ia ta-transportation routes and surface
waters; the name of the receiving wah'ters�to h the stormwater outfalls
discharge, or if the discharge is to a"municipal separate storm sewer system, the
name of the municipality and the udItimaterreceivi.ng waters; and accurate latitude
and longitude of the poif-strmwater discharge associated with industrial
activity. The general locatian_ma-1 or alternatively the site map) shall identify
whether any receiving Ovate =ar mpaired (on the slate's 303(d) list of impaired
waters) or if the site is located�ii-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.
PartII Pagel of 15

Permit No. NCS000076
(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 III, Standard Conditions, Section B, Paragraph 3.
2. 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 following:
(a) Feasibility Study. A review of the technical and econoirnic feasibility of changing
the methods of operations and/or storage ractices tb eliminate or reduce exposure
P / g pri
of materials and processes to rainfall and run -on-flbirvsWherever practical, the
r k /l � - 7 .
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 Require' meQttss afid Records. Secondary containment is
required for: bulk storage of liqu d mate storage in any amount of Section 313
of Title III of the Superfund eudments and Reauthorization Act (SARA) water
priority chemicals: and storage m 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(tored materials and their associated secondary containment
areas shall be maintained..lf the secondary containment devices are connected to
stormwater conveyan esystems, 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. For facilities subject to a federal oil Spill
Prevention, Control, and Countermeasure Plan (SPCC), any portion of the SPCC Plan
fully compliant with the requirements of this permit may be used to demonstrate
compliance with this permit
(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.
PartII Page 2 of 15

Permit No. NC5000076
3. 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
increased 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. A
4. Preventative Maintenance and Good Housekeepii g— ogram. A preventative
maintenance and good housekeeping program Ns all be d gel ped 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 are s,,and I roads), all drainage features and
structures, and existing structural BMPs.The program shall establish schedules of
inspections, maintenance, acid housekeepinWactivities of stormwater control systems,
as well as facility equipmen ficiI eas, and facility systems that present a potential
for stormwater exposure or stor�mwaater pollution where not already addressed under
another element of the SPPP. Inspection of material handling areas and regular
cleaning schedules of these areasshall be incorporated into the program. Timely
F-
compliance with the establish schedules for inspections, maintenance, and
housekeeping shall be r svrded and maintained in the SPPP.
5. 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 11 B, C, and D of this
permit.
6. 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.
7. Responsible Party. The SPPP shall identify a specific position or positions responsible
for the overall coordination, development, implementation, and revision of the SPPP.
Part II Page 3 of 15

Permit No. NCS000076
Responsibilities for all components of the SPPP shall be documented and position
assignments provided.
8. 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 ofsignifrcantspills or leaks of pollutants for the previous three
(3) years, or the notation that no spills have occurred (element of the Site

shall submit a time schedule the Director for modifying the SPPP to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part 1I1, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution
Prevention Plan and all appropriate BMPs consistent with the provisions of this permit,
in order to control contaminants 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 (S) years and made
available to the Director or the Director's authorized representative immediately upon
request.
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1.
All analytical monitoring shall be performed during a measureable storm event at each
Part 11 Page 4 of 15

Permit No. NCS000076
stormwater discharge outfall (SDO). Only SDOs discharging stormwater associated with
industrial activity must be sampled (See Definitions).
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 DEMLR Regional Engineer. See Definitions

outfalls prevents collecting all samples within the first 30 minutes, sampling shall begin within the first 30
minutes, and shall continue until completed.
3 Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted. A copy of the Division's letter granting ROS shall be
kept on site.
4 For each sampled measureable storm event, the total precipitation must be recorded. An on -site rain gauge
is required. Where isolated sites are unmanned for extended periods of time, a local rain gauge reading
may be substituted for an on -site reading.
The permittee shall complete the analytical samplings in accordance with the schedule
specified below in Table 2, unless adverse weather conditions prevent sample collection
(see Adverse Weather in Definitions). Sampling is not required outside of the facility's
normal operating hours. A minimum of 60 days must separate Period 1 and Period 2
sample dates, unless monthly monitoring has been instituted under a "Tier Two"
response. Inability to sample because of adverse weather conditions must be documented
in the SPPP and recorded on the DMR. The permittee must report the results from each
sample taken within the monitoring period (see Part 111, Section E). However, for purposes

Failure to monitor semi-annually peu'permit terms may result in the Division requiring
monthly monitoring for a(D parameters for a specified time period. "No discharge" from an
outfall during a monitoring riod does not constitute failure to monitor, as long as it is
properly recorded and reported.
The permittee shall compare monitoring results to the benchmark values in Table 3.
Exceedances of benchmark values require the permittee to increase monitoring, increase
management actions, increase record keeping, and/or install stormwater Best Management
Practices (BMPs) in a tiered program. See below the descriptions of Tier One, Tier Two, and
Tier Three response actions below. In the event that the Division releases the permittee from
continued monthly monitoring and reporting under Tier Two or Tier Three, the Division's
release letter may remain in effect through subsequent reissuance of this permit, unless the
release letter provides for other conditions or duration.

IIf: The first valid sampling results are above a benchrr rk valueypif outside of the benchmark range, for any
parameter at anv outfall:
Then: The permittee shall:
1. Conduct a stormwater management ins ection_of the facility within two weeks of receiving sampling
results.
2. Identify and evaluate possible&Qses!f'tLhH691enchmark value exceedance.

improvements to reduce con entrati f the parameters of concern, and/or to bring concentrations
within the benchmark range.-�
4. Implement the selected fea iris ble actions within two months of the inspection.
S. Record each instance of a Toe response in the SPPP. Include the date and value of the benchmark
exceedence, the inspection date, the personnel conducting the inspection, the selected actions, and the
date the selected actions were implemented.
6. Note: Benchmark exceedances for a different parameter separately trigger a tiered response.
If: The first valid sampling results from two consecutive monitoring periods(omitting periods with no
discharge) are above the benchmark values, or outside of the benchmark range, for any specific parameter at
a specific discharge outfall;

Permit No. NCS000076
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all -parameters. The permittee shall conduct
monthly monitoring at every outfall where a sampling result exceeded the benchmark value for two
consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until three
consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow" to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise the
option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional
Engineer may direct the response actions on the part of the permittee as provided in Tier Three,
including reduced or additional sampling parameters or frequency.
S. Maintain a record of the Tier Two response in the SPPP.
6. Continue Tier Two response obligations throughout the permitxrenewal process.

If: The valid sampling results required for the permit monitoring penods exceed the benchmark value, or
are outside the benchmark range, for any specific paramete any specific outfall on four occasions, the
permittee shall notify the DEMLR Regional Engineer in writing Within 30 days of receipt of the fourth
anal cal results;
Then: The Division may but is not limited to:
• require that the permittee revise, increaser ZecrelsWethe monitoring and reporting frequency for
some or all of the parameters herein;
• require sampling of additional or -substitute parameters;
• require the permittee to install st�c-Wral�stormwater controls;
• require the permittee to implemen 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;
• require the oermittee to continue Tier Three obligations through the hermit renewal process.
This site discharges to impaired waters experiencing problems with mercury. If a Total
Maximum Daily Load (TMDL) is approved for this segment of Spring Branch, the permittee
may be required to monitor for the pollutant(s) of concern in the future and submit results
to the Division. The Division will consider the monitoring results in determining whether
additional BMPs are needed to control the pollutant(s) of concern to the maximum extent
practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a
timetable for incorporation of those BMPs into the Stormwater Pollution Prevention Plan,
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the Stormwater
Pollution Prevention Plan (SPPP) and identify new potential sources of stormwater
pollution. Qualitative monitoring of stormwater outfalls must be performed during a
measurable storm event
Part Il Page 8 of 15

Permit No. NCS000076
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed semi-annually as
specified in Table 4, and during required analytical monitoring events (unless the permittee
is required to perform further qualitative monitoring per the Qualitative Monitoring
Response, below). Inability to monitor because of adverse weather conditions must be
documented in the SPPP and recorded on the Qualitative Monitoring Report form (see
Adverse Weather in Definitions). Only SDOs discharging stormwater associated with
industrial activity must be monitored (See 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.

permit prompt monthly monitoring. See Table 2 for schedule of monitoring periods through the end of
this permitting cycle. The permittee must continue qualitative monitoring throughout the permit renewal
process until a new permit is issued.
2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(SDO) regardless of representative outfall status.
A minimum of 60 days must separate monitoring dates, unless additional sampling has
been instituted as part of other analytical monitoring requirements in this permit.
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, below.
Part II Page 9 of 15

Permit No. NCS000076
A written record of the permittee's investigation, evaluation, and response actions shall be
kept in the Stormwater Pollution Prevention Plan.
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, identifying new potential
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, the
Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency for some
or all parameters (analytical or qualitative)
• require the permittee to install structural sto wa&,Zontrols;
require the permittee to implement other stormwater control " easures;
• require the permittee to perform upstream and downs eazn monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modica#tons qualify for a No Exposure Exclusion.
SECTION D: ON -SITE VEHICLE'MA TENANW- MONITORING REQUIREMENTS
Facilities that have any vehicle maintenance activity occurring on -site which uses more
than 55 gallons of new motor oil p month when averaged over the calendar year
shall perform analytical monitoring as specified below in Table S. All analytical
monitoring shall be performed during a measureable storm event at all stormwater
discharge outfalls (SDOs) tha discharge stormwater runofffrom vehicle maintenance areas,
and in accordance with the schedule presented in Table 2 (Section $).

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000076
Corning Incorporated - Wilmington
New Hanover County
Dear Ms. Adams:
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please
review the draft carefully to ensure thorough understanding of the conditions and
requirements it contains.
The draft permit contains the following significant changes from the facility's current permit:
1. You are required to collect analytical and qualitative monitoring samples during
"measurable storm events" as defined in Part II, Section B. This term is different
from the "representative storm event" in earlier permits.
2. Requirements for the Stormwater Pollution Plan (SPPP) have been updated in Part II,
Section A.
3. Changes have been made to multiple monitoring parameters, including a change to
one benchmark. Stormwater benchmarks are not permit limits, but rather guidelines
for implementing the Stormwater Pollution Prevention Plan (SPPP). A benchmark
exceedance is not a permit violation; however, the permittee must respond to
exceedances as directed in the Tiers.
The Oil & Grease parameter is changed to Non -polar Oil & Grease [EPA
Method 1664 (SGT-HEM)]; the benchmark for Non -polar Oil & Grease is 15
mg/L.
• Total Nitrogen; Nitrate+Nitrite; and Total Residual Chlorine parameters
have been removed from your stormwater permit. This does not affect
requirements to monitor these and other parameters required by your NPDES
wastewater permit NC0003794.

• Vehicle maintenance monitoring parameters have been revised as follows:
o Non -Polar Oil & Grease [EPA Method 1664 (SGT-HEM}] replaces
Oil & Grease/TPH. This requirement appears in all individual
stormwater permits; however, it only applies to facilities that
perform onsite vehicle maintenance activities. if the facility begins
vehicle maintenance during the permit cycle, the requirements shall
apply.
o pH monitoring is no longer required for discharges only associated
with vehicle maintenance activities.
4. A new section on Special Conditions has been added in Part It, Section E to comply
with federal regulations requiring electronic submittal of discharge monitoring
reports. This section of the permit will become effective December 21, 2016.
5. Representative Outfall Status will continue to be granted such that Outfall 008 can
be represented by Outfall 003. In accordance with the recommendation of our
Wilmington Regional Office, you may also discontinue analytical stormwater
monitoring for all parameters at Outfalls 001 and 002. Analytical monitoring shall
continue at Outfalls 003, 004, and 005 for pH, TSS, and Non -Polar Oil & Grease.
Qualitative monitoring shall continue to be required at all outfalls, including Outfalls
001, 002, and 008.
Please review the draft permit and submit any comments to me no later than 30 days
following your receipt of the draft. Comments may be emailed to me at
julie.ventaloro(@mcdenr. _pvv or mailed to my attention at NCDEQ, Land Quality Section,

Central Office Review Summary:
1. Special Issues:
o Added a new section on Special Conditions in Part II, Section E to comply with
federal regulations requiring electronic submittal of discharge monitoring
reports.
o Propose eliminating monitoring requirements for Total Nitrogen as well as
Nitrate+Nitrite. The facility does not discharge to NSW waters so nutrients are
not a primary concern. Besides soot, not clear that there are any sources of
nitrogen in their process. Total Nitrogen monitoring is required by their
wastewater permit. CO would like RO's concurrence on removing these
pear meters from the permit.

1612 Mail Service Center 1 512 North Salisbury Sheet [ Raleigh, NC 27699-1612
919 707 9200 T

o Propose eliminating monitoring requirement for Total Residual Chlorine. It is
unlikely to be found in elevated levels in stormwater at this facility due to
dissipation. Monitoring from the past 8 years shows levels well below
benchmark. Total Residual Chlorine monitoring is required by their wastewater
permit. CO would line RO's concurrence on removing this parameter from the
permit.
o Permittee has requested relief from all analytical monitoring requirements
because they had no sample results above benchmark values during this last
permit cycle. While this is encouraging, it would be atypical to remove all
sampling requirements for an individual permit. CO recommends removal of the
three parameters described above (TN, NO2+NO3, TRC) but retention of the
standard parameters TSS, Oil & Grease (TPH) and pH. CO would like RO's
concurrence on this approach.
o The Oil & Grease parameter is changed to Non -polar Oil & Grease [EPA
Method 1664 (SGT-HEM)) for consistency with other permits. The benchmark
for Non -polar Oil & Grease is 15 mg/L.
o In 2008, the facility stopped analytical monitoring at Outfall #008, citing
representative outfall status. CO would like RO's confirmation that they have
been approved for ROS at Outfall #008. if this is the case, which outfall
represents Outfall #008?
o Requirements for the Stormwater Pollution Plan (SPPP) have been updated in
Part II, Section A.
o Permittee will be required to collect analytical and qualitative monitoring samples
during "measurable storm events" as defined in Part II, Section B. This term is
different from the "representative storm event" in earlier permits.
2. Changes at the facility since previous permit:

Introduction
The Coming Incorporated facility in Wilmington has two (3) NPDES outfaiis for non -
contact wastewater and stormwater, four (4) existing NPDES outfalls for stormwater only, and
eight (8) stormwater outfalls serving areas exempt from NPDES permitting_ Attachment A contains
a table listing the estimated total drainage area acreage for the outfalls discussed in the next sections.
Outfall 001 SCC currently services a constructed stomwMer pond (Pond 5), however, future
construction of a cooling tower system is listed in permit NC0003794, but is not currently constructed.
NPDES Permitted Outfalls
Outfalls 001, 002 and 001 SCC
NPDES Permit No. NCO003794 covers wastewater discharges from the facility via NPDES
Outfalls 001 and 002 (see Drawing labeled "Overall Sheet). Outfalls 001 and 002
also discharge stormwater runoff from portions of the facility where chemical storage, loading
and unloading occur. Outfall 001 also receives stormwater runoff from a portion of the parking
area labeled Drainage Area 14. This drainage area is considered to be an exempt area since
it is only a parking lot (see Drawing Sheet labeled "Quad 3"). Outfall 001 has a
total drainage area of 2.24 acres. This total does not include the exempt Drainage Area 14,
Outfall 002 has a total drainage are of 9.78 acres with 6.81 acres being impervious.
Outfall 001 SCC has a total drainage area of approximately 30.35 acres, with 4.56 being impervious.
Outfalls 003, 004, 005, S 008
• Drainage Area 3 contains manufacturing assets not currently in use. The property is bounded
on the north, south and east largely by the property lines. See Drawing Sheet labeled "Quad 1"
and "Quad 4'). The total drainage area is 6.81 acres with 5.50 acres being impervious. Drainage
Area 3 discharges through Outfall 003 via a stormwater retention pond constructed in 1998.
Drainage Area 4 receives stormwater drainage from a portion of the Manufacturing Building
roof (see Drawing Sheet labeled "Quad 4'). All 2.12 acres of Drainage Area
4 are impervious. Drainage Area 4 discharges through Outfall 004. Also, exempt Drainage
Area 5D discharges through Outfall 004. Drainage Area 5D is 0.64 acres of impervious surface.
Drainage Areas 5A and 5B discharge to a stormwater retention pond located prior to Outfall
005. The retention pond was constructed in 1996. Drainage Area 5A contains 2.26 total acres
including 0.71 impervious acres. Drainage Area 5B is 6.14 acres with 4.53 acres impervious.
Two exempt drainage areas discharge through Outfall 005. Exempt Drainage Area 5C is
comprised of a manicured front lawn, with 2.21 total acres and 0.33 acres impervious. Exempt
Drainage Area 5D receives stormwater drainage from an administrative office building roof
(.64 acres impervious).
Drainage Area 16 discharges to a stormwater pond constructed in 2001. See Drawing
Sheet labeled "Quad 4". The drainage area consist of 6.81 acres, with 5.50 being impervious.
The drainage area consists of manufacturing support equipment, pollution abatement equipment
and cooling towers.
Outfalls Exempt from NPDES Permitting
Eight (8) outfalls are identified on the storm drain piping drawings as "Exempt
10 Outfalls (EO)". These outfalls receive water from areas containing no industrial activity and no
potential for stormwater contamination; therefore, these outfalls and corresponding drainage
area are exempt under NPDES regulations.

0
Drainage Areas Not Being Discharged Through Outfalls
The remainder of the Coming Incorporated property, Drainage Area 6 and Drainage Area 9,
is completely pervious with no direct discharge points from the site. Drainage Area 6 is 0,49
acres and Drainage Area 9 is 10.22 acres.
Site Drainage Controls
The Wilmington plant system design standard requires storm drain systems to function during a
50-year storm event. The three (5) e)dsting stormwater retention ponds meet the requirements of
NCDWQ State Stormwater Management Systems permit program.
All secondary containment systems located at the facility have been upgraded to retain the
capacity of the largest vessel plus a 24-hour/25-year stone event (defined as a inches of rainfall
for the Wilmington area). The Stonnwater Pollution Prevention Plan (SP3) includes keyed lockouts
of the drain systems. The Area SP3 team identified "appropriate testing" and record keeping
provisions during Best Management Practices (BMP) development. Collected stormwater from all
secondary containment systems is evaluated prior to making a determination to discharge any
collected stormwater to the outfalls. There is an aftemate system available for the discharge of
contaminated stormwater. Collected stormwater can be redirected, if required due to contamination,
to the Pollution Abatement Process for pretreatment prior to discharge to the City of Wilmington WWTP.

Best Management Practices
The Corning Incorporated facility in Wilmington relies on BMP's as well as engineered
structures to control stormwater and stormwater contamination. Following is a list of
some of the BMP's practiced at this facility.
1) Cooling tower chemicals stored in secondary containment
2) Diesel Fuel stored in secondary containment
3) Monthly testing of high level alarms in the sanitary lift stations
4) Raw materials are dispensed and waste materials are accumulated in an
enclosed building with diking and a floor sump
5) Waste drums are stored under cover in a sloped and diked area
6) Pollution abatement equipment is contained is secondary containment
• 7) Bulk raw materials are contained in secondary containment dikes
8) Stormwater accumulation in secondary containment dikes must be evaluated
before pumping to the outfall system. Water that fails criteria is sent to the
neutralization system and eventually to the POTW system.

must apply to the Division of Water Quality (DWQ) for renewal of you r permit. Enclosed you will find an
individual permit Renewal Application Form, Supplemental Information request, and Stormwater Pollution
Prevention Plan Certification for your facility.

application for renewal of this permit. Until your permit renewal is completed and you receive a new permit,
please continue to comply with all conditions and monitoring requirements in your expired NPDES
stormwater permit.

to $25,000 per day.

manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff 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 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 directly 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, and 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 the material stored within the containment area. 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 narrative description shall be provided 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 the potential of pollutant sources to contribute
Part II Page 4 of 10

Permit No. NCS000076
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. 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 SPCC plan 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.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. inspection of material handling areas and regular cleaning schedules of
these areas shall be incorporated into the program.

minimum on an annual basis on proper spill response and cleanup procedures and
preventative maintenance activities for all personnel involved in any of the facility's
operations that have the potential to contaminate stormwater runoff. Facility personnel
(or team) responsible for implementing the training shall be identified.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the PIan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance that has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis. The annual update
shall include an updated list of significant spills or leaks of pollutants for the previous
three years, or the notation that no spills have occurred. The annual update shall include
re -certification that the stormwater outfalls have been evaluated for the presence ofnon-
stormwater discharges.
The Director may notify the permittee when the Plan 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 Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions; Section B, Paragraph 3) to the Director that the changes
have been made.

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours.

Permit No. NCS000076
Corning Inc.
New Hanover County
Dear Ms. Adams:
In response to Corning, Incorporated's comments regarding NPDES Stormwater Permit NCS000076 I
have drafted an email and am responding in kind to your numbered questions below.
1. To grant representative outfall status (ROS) for analytical monitoring we would prefer to have
monitoring data (generally 4-5 data collection points) to support the request for ROS. In Coming's case, as
we did not have any previous analytical stormwater monitoring data from any outfall after a rain event,
we are interested in seeing analytical monitoring data from each outfall.
You may apply for Representative outfall status by submitting a request to us in writing with maps,
numbered drainage areas, numbered outfalls, and a description of which outfalls you are requesting ROS
for which specific basins.
If you choose to apply for ROS, your case would be substantially strengthened with the inclusion of
supporting data. If you have already submitted data from your analytical monitoring you may request
that we consider that data. Alternatively, if there are eligible Representative Storm Events that you want
to sample before your scheduled sampling time you may collect and submit that monitoring data with
your request.
2. In Part VI, Definitions of your permit the definition of Grab Sample (11.) states it is "An individual
sample collected instantaneously. Grab samples that will be directly analyzed or qualitatively monitored
must be taken within the first 30 minutes of discharge." Please use this definition to guide your sampling.
If you have any questions please contact me.
3. Your plan for analyzing field samples is satisfactory.
4. Yes you are correct. You will have one year to update your new SP3 plan.
5. Both the Qualitative Monitoring Form and a "Generic Discharge Monitoring Report Form" to be used
for Analytical monitoring can be found at
http://h2o.enr state. nc-us/su/Forms_Doeuments.htm# miscforms
Each form is located at
httpJ/h2o.enr.state.nc.us/su/documents/SWU-242QualitativeMonitoringForm.pdf and at
http://h2o.enr.state.nc.us/su/PDF_Files/DMR_Fonns/SWU246_Ceneric_DMF-pdf, respectively.
Please use these forms when reporting data. Please note that only the analytical monitoring data needs to
be submitted each monitoring period. I am attaching a copy with this letter.

Re: Draft NPDES Stormwater Permit
Permit No. NCS000076
Coming Incorporated, New Hanover County
Dear Ms. Jones,
Coming Incorporated t 910-784-7200
310 North College Road www mming.com
Wilmington, NC 28405
Included in this letter are Coming Incorporated's comments concerning the draft NPDES permit referenced
above, and received by the facility on February 29, 2008.
I . In the existing permit and draft permit, within Section D, there is a paragraph on representative outfall.
We will submit a request to the Director (and cc: you) to request sampling at a reduced number of
outfalls, since all of our outfalls have substantially identical stormwater discharges_
2. Additional clarification is needed regarding when a representative storm event occurs, how much time is
available for sampling? The event is defined as soon as 0.1 inches of water is collected, but at what
point in time is sampling no longer allowed - meaning what is the allowable time window of sampling?
At some point in time, it would be considered too late to sample, but there is not language defining this.
There is language in the permit regarding sampling from a pond (within 30 minutes of discharge), but no
similar language for a direct outfall.
3. For the analytical monitoring requirements, we are assuming since our facility is field certified for pH
and total residual chlorine, those analyses will be done on -site (pH has time requirements on how soon
the sample must be analyzed). For the remaining parameters, we will sample and submit to a local
certified lab for analysis.
4. Verification of the compliance schedule. Our site stormwater pollution prevention plan will need to be
modified to meet the new, additional requirements of this renewal permit. By the language in Part
II I.A. I - Compliance Schedule, I am assuming that we have already developed and implemented the SP3
plan, and will update the plan within the year (updated thereafter on an annual basis). Please verify the
allowed timing for updates.
5. Lastly, we will check the DWQ web -site for applicable reporting forms and/or formats for the semi-
annual reporting requirements.
Thanks. Please call me at [phone] if there are any questions.
Sincerely,

Subject: Draft NPDES Stormwater Permit
Permit No. NCS000076
Coming, Inc. RA
New Hanover County
Sullins, Director
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from this facility's current permit:
Anal 'cal monitoring than es:
1. New analytical monitoring procedures have been implemented. TSS, TN, NO2 NO3- N, Total
Residual Chlorine, Oil and Grease, and pH has been added to the analytical monitoring
requirements. Please see Table 1 for a summary of requirements.
2. All analytical monitoring has been set to semi-annually during a representative storm event as
defined in Part Q Section B. The permittee must also document the total precipitation for each
event. If no discharge occurs during the sampling period, the permittee must submit a
monitoring report indicating "No Flow" within 30 days of the end of the six-month sampling
period. Additionally, samples must be taken a minimum of 60 days apart, as specified in Table 2.
3. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of
benchmark values require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered
program. If the sampling results are above a benchmark value, or outside of the benchmark
range, for any parameter at any outfall then the facility shall follow the Tier 1 guidelines which
require a facility inspection within two weeks and implementation of a mitigation plan within
two months. If during the term of this permit, the sampling results are above the benchmark
values, or outside of the benchmark range, for any specific parameter at a specific discharge
outfall two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which
require a repetition of the steps listed for Tier 1 and also immediately institute monthly
monitoring for all parameters at every outfall where a sampling result exceeded the benchmark
value for two consecutive samples.
4_ You are required to collect all of the analytical and qualitative monitoring samples during
representative storm events as defined in Part II Section B. Qualitative monitoring is required
regardless of representative outfall status.
5. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of
Tables 1, 4, and 5.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
and event duration parameters are in this permit, however.)
7. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with
analytical and qualitative monitoring. This requirement appears in all Individual Stormwater

permits, however it only applies to facilities that do vehicle maintenance. If the facility begins
vehicle maintenance during the permitted timeframe then the requirements shall apply.
Other permit changes:
1 _ Additional guidance is provided about the Site Plan requirements. The site map must now
identify if the receiving stream is impaired and if it has a TMDL established. It must also
describe potential pollutants in each outfall. The map requirements are stated more explicitly.
And, the site plan must contain a list of significant spills that have occurred in the past three
years and also must certify that the outfalls have been inspected to ensure that they do not
contain non-stormwater discharges. Additional information is provided in Part II Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II
Section A. More details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in
Part H Section A. The plan must also be updated annually to include a list of significant spills
and to certify that the outfalls do not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's
stormwater management controls as specified in Part lI Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If
industrial materials and activities are not exposed to precipitation or runoff as described in 40
CFR §122.26(g), the facility may qualify for a No Exposure Exclusion from NPDES stormwater
discharge permit requirements. Additional information is provided in Part I Section A.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Conunents should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.

Difficul Rating:

Special Issues Explanation:
• Compliance: The facility only submitted data for one monitoring point in 2001. We don't
have data after 6/15/2004. Data was submitted for WW — considering adding to file.
• Benchmarks: No benchmarks were used in the old permit — ho analytical monitoring was
asked for in previous samples.
• Location: A TMDL has been issued for Smith Creek_ This facility discharges to a tributary
of Smith Creek — had to wait for reply from TMDL unit until they had done their analysis. Difficult
to assess as to whether or not this facility would contribute to impairment due to no previous
Page 1 of 9

NCSOOOAAN
previous information and confusion as to whether or not the TMDL was issued based on low DO
(incorrect) or impaired biologicals (correct). No T&E species present.
• Other Challenges: Facility is discharging about 100,0D�of_chiorine-containing chemicals
(Chlorine and Hydrogen Chloride), 200 Tons/year NOx, and 110,000 Ibsty re Sox by air — mainly
by stack. Review of necessity of pH, N, P and Chlorine/Chloride anatyti l-s`a p ml g due to
deposition/roof runoff was necessary. Plan and actual stormwater path was complex and difficult
to completely understand without site visit.
Description of Onsite Activities:
Corning, Inc. plant manufactures fiber optic fibers at their Wilmington, NC. Fiber optic fibers are
made of high purity glass, ceramic materials, and polymers. They are used products for the
telecommunications, flat panel display, environmental, semiconductor, and life sciences industries.
The glass for the preform is made by a process called modified chemical vapor deposition
(MCVD). In MCVD, oxygen is bubbled through solutions of silicon chloride (SiCI4), germanium chloride
(GeC14) and/or other chemicals. The precise mixture governs the various physical and optical properties
(index of refraction, coefficient of expansion, melting point, etc.). The gas vapors are then conducted to
the inside of a synthetic silica or quartz tube (cladding) in a special lathe. r

or Stormwater discharge.
o Air Permit:
a. 3712900049
2. General Observations:
o Inspection on 8/6/2007 by Pat Durrett due to complaint. No violation issued. This was related to
parking lot expansion and State Stormwater Permit SW8950826. A lot of algae in the basin,
heavily wooded vegetation has accumulated on basin walls, overflow and bypass need to be
checked to see that they are at correct elevation. Conducted by Pat Durrett — point source
compliance unit_
a. Pat did pond renewal permit.
o Tom Moore: Came in 2006 for NPDES inspection. Audit on 9114106. OVO f,-,-�
o This plant discharges to an unnamed tributary to Spring Branch which discharges to Smith Creek
- an impaired waterbody. TMDL list
a. They have releases into air by permit. "This may be important for their roof runoff. For
instance Outfall 004: from area 4 - all roof. They appear to describe some of this area as
"exempt". This may be important, as this seems like drainage of major roof area - air
discharge - air/rain/roof /gutter/SW discharge may be an important monitoring point. Does
not appear to be treated in Pond 1 - appears to bypass this directly to edge of property.
Need clarification.
b. This may be an important monitoring point.
o There appear to be two expansions of the parking lot and two expansions of Glass Tower 5 -this
needs to be confirmed. Ahy19
o Went on site visit - generally was very clean.
3. Impairment: Smith creek is on 303(d) list. TMDLba§ been created for Smith Creek for 2008 -Cape
Fear Subbasin 03-06-23. Coming drains to.U+ bf Spring Branch which drains to Smith Creek.
Distance from Corning to Spring Branch is abo t 0 -miles distance from Spring Branch to Smith
Creek is about 1 mile. Basinwide Plan recommedds monitoring for Total Residual Chlorine, pH, DO,
BOD, COD, N & P. Also Methylene chloride - need to verify if this is in use - also very hard to test for
due to contamination in chemistry labs.
4. Threatened and Endangered:
[D,9
Page 3 of 9

Ncsoo0
o No federal threatened or endangered species were found near site using the Natural
Heritage Threatened and Endangered Species List Database.
5. Lgcation:
o See Impairment above — Drains to Spring Branch which drains to Smith Creek -- which is
listed on TMDL . Site is about 1.5 miles from Smith Creek.
6. Industrial Changes Since Previous Permit:
a Changes as of submittal: Included.
o Changes since submittal: No.
7. Analytical Monitoring Notes:
o No analytical monitoring has been done in the past for stormwater.
o Smith Creek which Spring Branch flows into is on 303d Fist for Impaired Biologicals. Coming
also discharges 100,000 lb/year of Chlorine/Hydrogen Chloride by air, 200 Tons/year NOx,
and some SOx as well. We will ask them to monitor Chloride, TN, Nitrate -Nitrite Nitrogen, and
pH.
o Some analytical for outfalls 001 and 002 has been done by waste water as this is a combined
outfall of stormwater and WW from boiler blowdown.
8. Qualitative Monitoring Notes:
o See qualitative monitoring information below. No qualitative data from Stormwater on file.

Analytical Monitoring: NA
Revised Permit Recommendations: Analytical Monitoring:
r 1. Adding -
a. Chlorides, Nitrate + Nitrite Nitrogen, Total Nitrogen (TN), TSS and pH.
i. Drains to Smith Creek (1.5 miles away) which is on 303d list for impaired waters for
impaired biology.
ii. Added Chorides to monitoring - they emit about 100,000 Ibslyear of Chlorine plus
' hydrochloric acid in air. This may be a problem as it may go directly from roof to gutter
and then out without treatment off the site. Stream discharges to is on TMDL list for
p DOrmpaired biologicals.
t iii. Added TN and Nitrates/Nitrites as they emit close to their limit of NOx and stream
?All
discharges to is on TMDL list for DO/impaired biologicals.
iv. TSS: There was some very fine particles from bag houses, therefore we believe TSS
would be a useful parameter for monitoring.
v. pH has been added to the analytical monitoring requirements.
2. analytical monitoring has been set to semi-annually during a representative storm event as defined
in Part 11 Section B. The permittee must also document the total precipitation for each event. If no
discharge occurs during the sampling period, the permittee must submit a monitoring report indicating
"No Flow" within 30 days of the end of the six-month sampling period. Additionally, samples must be
taken a minimum of 60 days apart, as specified in Table 2.
3. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of
benchmark values require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater Best Management Practices (BMPs) in a tiered
program. If the sampling results are above a benchmark value, or outside of the benchmark range,
for any parameter at any outfall then the facility shall follow the Tier 1 guidelines which require a
facility inspection within two weeks and implementation of a mitigation plan within two months. If
during the term of this permit, the sampling results are above the benchmark values, or outside of the
benchmark range, for any specific parameter at a specific discharge outfall two times in a raw
(consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of the steps
listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
4. The permittee is required to collect all of the analytical and qualitative monitoring samples during
Page 5 of 9

.NCS000X'R
representative storm events as defined in Part II Section B. Qualitative monitoring is required
regardless of representative outfall states.
5. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of
Tables 1, 4, and 5.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall
parameter is in this permit, however.)
7. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical
and qualitative monitoring. _
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if
the receiving stream is impaired and if it has a TMDL established. It must also describe potential
pollutants in each outfall. The map requirements are stated more explicitly. And, the site plan must
contain a list of significant spills that have occurred in the past three years and also must certify that
the outfalls have been inspected to ensure that they do not contain non-stormwater discharges.
Additional information is provided in Part II Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section
A. More details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part II
Section A. The plan must also be updated annually to include a list of significant spills and to certify
that the outfalls do not contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
1. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial
materials and activities are not exposed to precipitation or runoff as described in 40 CFR §122.26(g),
the facility may qualify for a No Exposure Exclusion from NPDES stormwater discharge permit
requirements. Additional information is provided in Part I Section A.
Discussions with penmittee: Jennifer Adams, Discussion 1 on January 3, 2008:
1. Is the legal name and owner of the facility still Coming, Incorporated?
a. yes
2. Have there been any facility or process changes in the past few years? For instance, are you still making the same
types of products or have you had any considerable expansions?
a. Same products, no significant expansions.
3. Do we have newer monitoring data than last submitted (last was 6/15/04)?
a. Corning will submit most current qualitative data — still believes that it was no issues. Will
send to us.
4. Did they used to do other analytical monitoring in the past? If so what and when? Did they stop
because they were not over the limit and their permit did not require them to do more?
a. No stormwater analytical monitoring.
b. One Stormwater [Waste Water permit actually] permit does require
i. From outfall 001. Flow, temperature, pH, Total residual monitoring (monthly)
Page 6 of 9

4q b
.NC5000%=
From Outfall 002: Flow, temperature, pH, total residual chlorine (all monthly), total
nitrogen N & and total P (quarterly). State Stormwater permit does not require this.
Do have analytical monitoring data from the WW permitting.
List of outfalls:
1. Outfalls 001, 002 (monitored instate Waste Water permit- NC0003794)
2. Outfall 001:
a. Chemical storage, loading and unloading
i. All outside, CP&L is double contained, waste storage and chem. Storage
areas are covered.
b. Outfall 001 receives from parking drainage area 14, lift station, parking area, water
tank, water well, treatment chemicals
c. Almost all of North side of the building goes through ouffail 001 - cooling towers,
water tank are outside and drain to this. Does not go to pond 1. Directly out to
outfall 001.
3. Outfall 002:
a. Outfall 002 no exempt area, has "discharge structure", from loose gravel and raw
material storage area, chemical storage, CP&L transmission substation, diesel fuel
storage
4. Pond 2 is exempt outfall - # E04A
a. Ms. Adams - Please clarify as to why exempt. Please email back.
5. Outfalls 003, 004, 005, 008
a. Outfall 003: drainage area 3
i. Area 3 is not currently in use. Manufacturing building & area.
1. Is this being used again since 2004? NO.
ii. BUT Stormwater from Area 3 drains to pond 3, then to Outfall 003
1. Via underground pipe - discharge is at southeast corner.
iii. A: pond 3 is being used to collect stormwater, but manufacturing area 3 is
not.
b. Outfall 004: Permitted ouffall.
i. Goes down from roof, to gutters, pipe and then drainage ditch to outside of
property. Does not go to pond 1. Directly leaves the property.
ii. Does any of this go to Pond 1 ? No.
iii. Also exempt area 5D - although on map it may drain through 005. Need
clarification.
c. Outfall 005:
i. 5A and 5B drain to Pond 1 in quad 3 then to 005
ii. How does area 5A drain to outfall 005? Yes. This was newer construction -
5B and 5D. 5A is drainage and piped to pond 001.
iii. Area 5C is the grass area around the pond.
iv. Pond 1 is the largest pond. All ponds are wet detention ponds.
d. Outfall 008
L Area 16 is the entire area surrounding pond 4 - all goes to Pond 4, and then
discharges out 008.
ii. Drains area 1 b: support equipment, pollution abatement equipment and
cooling towers.
e. Why is 5D exempt and other roof structure draining to 004 is not exempt?
i. 4 and 4a were "grandfathered" [We need to clarify this point as we do not
usually accept this term for stormwater permitting).
f. Area 5A and 3 appear to be linked by outfalls/drains.
L Please clarify.

5. Pond 2:
a. Parking lot drains to this.
6. Pond 5/SCC (Smith Creek Complex):
a. CP&L switch gear yard and parking area. No vehicle maintenance done on site. No equipment
stored outside. Building and parking lot.
b. Acquired back in 1990S
c. J. Jones will check on to make sure that Coming does not need this area to be included.
i. Not a manufacturing facility
ii. Owned by corning
iii. Bought — does not use
iv. Another company.
7. New Plant manager — check to see if we need a new coversheet.
a. If you could please submit a new coversheet we would appreciate it to make it the most
current.
Notes:
Pond 1: This may be important as this seems like drainage of major roof area — this may be important it has air discharge and
air to rain to roof to gutter to SIW( discharge may be an important monitoring point. Does not appear to be treated at all in Pond
�� `brrof/`1M1�
Conversation with TKom Moore:
Corning is an environmental steward — in order to obtain steward level, they have to implement an
environmental management system — air, water, & waste. In general have always gone above and
beyond permit compliance, good documentation, good document control, qualified individuals.
Outside grounds are kept very very clean.
One issue — pretreatment inspection — process water into City of Wilmington, treated waste water goes
CCtq�jty of Wilmington.
Mostly Discharge directly into the environment.
Total Residual Chlorine: 17 ug/L — used a new method — get a new instrument to get down to that level.
Call Kip Glazier to get a copy of that. For those parameters that they were reporting — Thomas Moore
asked that they report using our standard method. However, they were within their permit limits. -
Chemical storage outside? Not sure.
Used to be title 5 for air permitting — removed.
Have a thermal oxidizer.
Speak with Brad Newland about air permit.

during the three (3) previous 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 certification statement will be signed in accordance with
the requirements found in Part Ill, Standard Conditions, Section B, Paragraph 3.
2. Stormwater Management PIan. 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
nonstructural measures. The stormwater management lanan, at a minimum, shall
incorporate the following: All �
a. Feasibility Study. A review of the tec cal and economic feasibility of changing
the methods of operations and/or sto a ces to eliminate or reduce exposure
of materials and processes to storn w, a%r. VJ'Frever practical, the permittee shall
prevent exposure of all storage a 'al handling operations, and
manufacturing or fueling ope io eas where elimination of exposure is
not practical, the storm%%a U nt plan shall document the feasibility of
diverting the stor,mv ff way from areas of potential contamination.
b. Secondary Cot P egt— ements and Records. Secondary containment is
required for: bntai stora liquid materials; storage in any amount of Section
313 of Title lLl f the S perfund Amendments and Reauthorization Act (SARA)
water priori chemi s; and storage in any amount of hazardous substances to
prevent leaks and ills 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 directly 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, and 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 the material stored within the containment area. 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 narrative description shall be provided 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 the potential of pollutant sources to contribute

significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. 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 SPCC plan 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 A.7rporated by reference into the
SPRP.
4. Preventative Maintenance and Good Houseke in ro preventative
maintenance program shall be developed. Th r 7centrol
s document schedules of
inspections and maintenance activities of sto t systems, plant equipment

position(s) responsib a overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance that has a significant effect on the
potential for the discharge of pollutants to surface waters. The Stormwater Pollution
Prevention Plan shall be reviewed and updated on an annual basis. The annual update
shall include an updated list of significant spills or leaks of pollutants for the previous
three years, or the notation that no spills have occurred. The annual update shall include
re -certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges_
The Director may notify the permittee when the Plan 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 Plan to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part 111, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours. A.I

• Benchmarks: No benchmarks were used In the old permit — no analytical monitoring was
asked for in previous samples.
• Location: A TMDL has been issued for Smith Creek. This facility discharges to a tributary
of Smith Creek — had to wait for reply from TMDL unit until they had done their analysis. Difficult
to assess as to whether or not this facility would contribute to impairment due to no previous

a*. **Corning will submit most current qualitative data - still believes
that it was no issues. Will send to us.*
4. Did they used to do other analytical monitoring in the past? If so what and
when? Did they stop because they were not over the limit and their permit did
not require them to do more?
a. No stormwater analytical monitoring.
b. One Stormwater Waste water permit actually] permit does require
i. From outfall 001: Flow, temperature, pH, Total residual monitoring (monthly)
ii. From outfall 002: Flow, temperature, pH, total residual chlorine (all
monthly); total nitrogen N & and total P (quarterly). State stormwater permit
does not require this. Do have analytical monitoring data from the WW
permitting.
List of outfalls,
1. Outfalls 001, 002 (monitored in state Waste Water permit -
NCo003794)
2. Outfall 001:

i. All outside, CP&L is double contained, waste storage and chem. Storage areas
are covered.
2. outfall 001 receives from parking drainage area 14, lift
station, parking area, water tank, water well, treatment
chemicals
3. Almost all of North side of the building goes through
outfall 001 - cooling towers, water tank are outside and
drain to this. Does not go to pond 1. Directly out to
outfall 001.
2. Outfall 002:
1. Outfall 002 no exempt area, has "discharge structure", from
loose gravel and raw material storage area, chemical

1. Outfall 003; drainage area 3
i. Area 3 is not currently in use. Manufacturing building & area.
1. Is this being used again since 2004? NO.
ii. BUT Stormwater from Area 3 drains to pond 3, then to Outfall 003
1. Via underground pipe - discharge is at southeast corner.
iii. A: pond 3 is being used to collect stormwater, but manufacturing area 3 is
not.
2. Outfall 004; Permitted outfall.
i. Goes down from roof, to gutters, pipe and then drainage ditch to outside of

Hi again Narayan,
I forgot to add that Corning also releases a significant amount of Hydrochloric Acid
- so I am wondering if you are significantly concerned about low pH in this
watershed? I believe low pH is toxic to fish.
Thanks,

Hello Narayan,
It was nice to meet you today. I am forwarding my first email -- I might not have
written the correct address the first time around. If you could please confirm
that you have received this email I would appreciate it.
If you can please take a look at the TMDL for the Lower Cape Fear and Smith
Creek. Additionally I believe they are releasing a lot of Chlorine and I wondered
if there were any concerns with fish or amphibians in this subbasin/area and if
you think the Chlorine could have a major effect on them.
Any help you can give would be much appreciated.
Thank you!

Hi Narayan,
I am renewing a stormwater permit for Corning, Inc in Wilmington, NC. The
stormwater from the site drains to a UT to Spring Branch which then drains to
Smith Creek. Smith creek is on 303(d) List and I see that a TMDL has been created
for Smith Creek for 2008 and the lower Cape fear has a TMDL under development for
the lower Cape Fear. The distance from Corning to Spring Branch is about 0.5-1
miles, and distance from Spring Branch to Smith Creek is about 1 mile. The
Stream index is 18-74-63-1 for the closest Spring Branch #. The lat is: 34 14'
54"N and Long:77 52' 17.98"W.
Do you have any specific recommendations for this site re: Smith Creek's low DO
and benthic invertebrates problems? le do you have any parameters you would like
monitored in the permit? Do you have any concerns about this area besides the
waste water treatment plant that was there, that I believe was shut down?
They also have a permit to discharge in air, but a lot of roof space -

development for the lower Cape Fear. The distance fi•oni Corning to Spring Branch Is about 0.5-1 miles, and
distance from Spring Branch to Smith Creek is about I mile. The Stream index is 18-74-63-1 for the closest
Spring Branch #, The lat is: 34 14' 54"N and Long:77 52' 1798"W.
Do you have any specific reconiniendations for this site re: Smith Creek's low DO and benthic invertabrates
problenis? le do you have any parameters you would like nionitored in tiie permit? Do you have any concerns
about this area besides the waste water treatnient plant that was there, that I believe was shut down?
They also have a perniit to discharge in air, but a lot of roof space - consequently rainwater to gutters and then to
stormwater can be a probleni. Here is the epa website that lists the cheniicals released into the air and by the
ww: there seems to be quite a lot of chlorine which I think maybe we should monitor for.

Notice About Duration of,Violations -- The duration of violations shown on this report is an estimate of
the actual duration of the violations that might be alleged or later determined in a legal proceeding. For
example, the start date of the violation as shown in the ECHO database is normally when the
government first became aware of the violation, not the first date that the violation occurred, and the
facility may have corrected the violation before the end date shown. In some situations, violations may
have been corrected by the facility, but EPA or the State has not verified the correction of these
violations. In other situations, EPA does not remove the violation flag until an enforcement action has
been resolved.

Hydrochloric Acid (Hydrogen Chloride)
7647-0l-o ., ..,...
Hazard Summary -Created In April 1992; Revised in January 2000
Hydrochloric acid has many uses. It is used In the production of chlorides, fertilizers,
and dyes, in electroplating, and in the photographic, textile, and rubber Industries.
Hydrochloric acid is corrosive to the eyes, skin, and mucous membranes. Acute (short-
term) Inhalation exposure may cause eye, nose, and respiratory tract irritation and
Inflammation and pulmonary edema In humans. Acute oral exposure may cause
corrosion of the mucous membranes, esophagus, and stomach and dermal contact may
produce severe burns, ulceration, and scarring in humans. Chronic (long-term)
occupational exposure to hydrochloric acid has been reported to cause gastritis, chronic
bronchitis, dermatitis, and photosensitizatlon-in workers. Prolonged exposure to low
concentrations may also cause dental discoloration and erosion. EPA has not classified
hydrochloric acid for carcinogenicity.
Please Note. The main source of information for this fact sheet is EPA's Integrated Risk
Informatio S Lem (IRIS), which contains information on Inhalation chronic toxicity of
hydrochloric acid and the Reference Concentration (gfC). Other secondary sources Include
the Hazardous Substances_ Data Bank (HSD6), a database of summaries of peer -reviewed
literature, and the Registry of Toxic Effects, of.Chem Ica l Substances (RTECS), a database of
toxic effects that are not peer reviewed.
Uses
Hydrochloric acid Is used in the production of chlorides, for refining ore In the
production of tin and tantalum, for pickling and cleaning of metal products, in
electroplating, In removing scale from boilers, for the neutralization of basic systems,
as a laboratory reagent, as a catalyst and solvent in organic syntheses, In the
manufacture of fertilizers and dyes, for hydrolyzing starch and proteins in the
preparation of various food products, and In the photographic, textile, and rubber
Industries.
Sources and Potential Exposure
• Occupational exposure to hydrochloric acid may occur via Inhalation or dermal contact
during its production and use. (1,2)
Assessing Personal Exposure
No Information was located regarding the measurement of personal exposure to
hydrochloric acid.

Health Hazard Information
Acute Effects:
• Hydrochloric acid is corrosive to the eyes, skin, and mucous membranes. Acute
Inhalation exposure may cause coughing, hoarseness, inflammation and ulceration of
the respiratory tract, chest pain, and pulmonary edema in humans. (1-4)
• Acute oral exposure may cause corrosion of the mucous membranes, esophagus, and
stomach, with nausea, vomiting, and diarrhea reported in humans. Dermal contact
may produce severe burns, ulceration, and scarring. (1-4)
• Pulmonary irritation, lesions of the upper respiratory tract, and laryngeal and
pulmonary edema have been reported in rodents acutely exposed by inhalation,
• Acute animal tests In rats, mice, and rabbits, have demonstrated hydrochloric acid to
have moderate to high acute toxicity from Inhalation and moderate acute toxicity
from oral exposure. (3)
Chronic Effects (Noncancer):
• Chronic occupational exposure to hydrochloric acid has been reported to cause
gastritis, chronic bronchitis, dermatitis, and photosensitization•in workers. Prolonged
exposure to low concentrations may also cause dental discoloration and erosion. (1-
3,6)
• Chronic Inhalation exposure caused hyperplasia of the nasal mucosa, larynx, and
trachea and lesions in the nasal cavity in rats. (4,6)
• The Reference Concentration (RfC) for hydrochloric acid is 0.02 milligrams per cubic
meter (mgg/m�3) based on hyperplasla of the nasal mucosa, larynx, and trachea in
�
rats. The .� Is an estimate (with uncertainty spanning perhaps an order of
magnitude) of a continuous inhalation exposure to the human population (including
sensitive subgroups) that is likely to be without appreciable risk of deleterious
noncancer effects during a lifetime. It Is not a direct estimator of risk but rather'a
reference point to gauge the potential effects. At exposures increasingly greater than
the RfC, the potential for adverse health effects increases. Lifetime exposure above
the RfC does not imply that an adverse health effect would necessarily occur. (4)
• EPA has low confidence in the study on which the RfC was based since it used only
one dose and had limited toxicological measurements; low confidence in the database
because the database does not provide any additional chronic or reproductive studies;
and, consequently, low confidence In the RfC. (4)
• EPA has not established a Reference Dose (RfD) for hydrochloric acid. (4)
Reproductive/Developmental Effects:
• No information is available on the reproductive or developmental effects of
hydrochloric acid in humans.
• In rats exposed to hydrochloric acid by inhalation, severe dyspnea, cyanosis, and
altered estrus cycles have been reported in dams, and increased fetal mortality and
decreased fetal weight have been reported in the offspring. (4,6)
Cancer Risk:
• No information is available on the carcinogenic effects of hydrochloric acid in humans.
• In one study, no carcinogenic response was observed in rats exposed via inhalation.
(1)
• EPA has not classified hydrochloric acid with respect to potential carcinogenicity. (4)
Physical Properties
• Hydrogen chloride is a common synonym for hydrochloric acid. (4)
• The chemical formula for hydrochloric acid is MCI, and its molecular weight Is 36.47
g/mol. (1,3)
• Hydrochloric acid occurs as a colorless, nonflammable aqueous solution or gas.
(1,3,4)
• Hydrochloric acid has an irritating, pungent odor, with an odor threshold of about 7

CHEMICALS IN THE ENVIRONMENT:
METHYLENE CHLORIDE (DICHLOROMETHANE) (CAS NO. 75-09-2)
prepared by
OFFICE OF POLLUTION PREVENTION AND TOXICS
U.S. ENVIRONMENTAL PROTECTION AGENCY
August 1994
Chemicals can be released to the environment as a result of their
manufacture, processing, and use. The EPA has developed information
summaries on selected chemicals to describe how you might be exposed to
these chemicals, how exposure to them might affect you and the environment,
what happens to them in the environment, who regulates them, and whom to
contact for additional information. EPA is committed to reducing
environmental releases of chemicals through source reduction and other
practices that reduce creation of pollutants.
WHAT IS METHYLENE CHLORIDE, HOW IS IT USED, AND HOW MIGHT I BE EXPOSED?
Methylene chloride (also called dichloromethane) is a colorless,
nonflammable liquid. It does not occur naturally but is produced in
large amounts (350 million pounds in 1992) by three companies in the
United States. Recent us production of methylene chloride has declined
(about 10% a year since 1988). Us demand for methylene chloride is
likely to continue to fall. The largest users of methylene chloride are
companies that make paint strippers. Foam makers use methylene chloride
as a blowing,agent. other companies use it to clean metal surfaces.
Methylene cF�loride can also be added to aerosol sprays or used to extract
unwanted material from foods and beverages, such as coffee.
Exposure to methylene chloride can occur in the workplace or in the
environment following releases to air, water, land, or groundwater.
Exposure can also occur when people use certain aerosol paint sprays and
paint strippers. Methylene chloride enters the body when breathed in
with contaminated air or when consumed with contaminated food or water.
It can also be absorbed through skin contact. It is not likely to remain
in the body due to its breakdown and removal.
WHAT HAPPENS TO METHYLENE CHLORIDE IN THE ENVIRONMENT?
Methylene chloride evaporates when �.� ed�to ai r. I-t-dis,solvw
w n-nixed with water. Most direct releases of methylene chloride to the
Ov-fftmeri-t-spe-tom r. Methylene chloridq- lsoo_euapaar_ates frs�water
and soil exposed to air. once in air, it is expected to break down to
ol:her chemicals because it is a liquid that does not b7�eoysto
oil,
metVl ene_ i_lo.c1�� t�iat_makes 7 is wa e--g u h'
the grnun.Cand enter groun water. Plants and animals are n
store methv en-d"ch1iH-44e.
HOW DOES METHYLENE CHLORIDE AFFECT HUMAN HEALTH AND THE ENVIRONMENT?
Effects of methylene chloride on human health and the environment
depend on how much methylene chloride is present and the length and
frequency of exposure. Effects also depend on the health of a person or
the condition of the environment when exposure occurs.
Breathing large amounts of methylene chloride for short periods of
Page 1

.1%
methylene chloride fact sheet
time adversely affects the human nervous system and the heart. Effects
range from unsteadiness and numbness in fingers and toes to
unconsciousness and death. The heart has to work harder, and the blood
carries less oxygen as the body breaks methylene chloride down to carbon
monoxide. Direct contact with methylene chloride liquid or vapor
irritates the skin and the eyes. These effects are not likely to occur
at levels of methylene chloride that are normally found in the
environment.
Human health effects associated with breathing or otherwise
consuming smaller amounts of methylene chloride over long periods of time
are not known. Laboratory studies show that repeat exposure to methylene
chloride causes kidney and liver damage and cancer in animals that
breathe air or drink water contaminated with the chemical. Repeat
exposure to methylene chloride may likewise cause cancer in humans.
Methylene chloride is not likely to cause environmental harm at
levels normally found in the environment. Reactions in air, although
slow, tend to eliminate methylene chloride before it reaches the upper
atmosphere in amounts sufficient to damage the ozone layer.

Hi Pat and Aisha,
I hope you both had a good Christmas and New Years. But now back
to work... I am reviewing this individual permit for Corning's
Stormwater and I had some questions for you I hoped you could
answer for me...
1) I think that you went on a site visit because of a complaint
- was there anything unusual there? I saw you noted in RIMS "A
lot of algae in the basin, heavily wooded vegetation has
accumulated on basin walls, overflow and bypass need to be
checked to see that they are at correct elevation". Do you have
any ideas as to why there might be so much algae? Do you think
this is due to their design, waste water emissions or...? Do you
think their stormwater is contributing to this in any way?
2) I noticed that there has been 2 increases in Tower 5, and 1 in
the parking lot - have you seen any other expansions?
3) It doesn't seem like they emit a lot of organics, Nitrogen or
Phosphorus - any comments? They emit a lot of chlorine and
hydrochloric acid through their stacks. One concern I have is
that it might be depositing on their roofs, and if rainwater is
running off it appears that it is directly going from the
guttering to an outfall and off the site - on what they are
calling "exempt".
4) Any other notes/comments/visits?
Thanks in advance for your help!
Jennifer Jones

OPPT Chemical Fact Sheet EPA 749-F-94-010
CHEMICALS IN THE ENVIRONMENT: CHLORINE (CAS NO. 7782-50--5)
prepared by
OFFICE OF POLLUTION PREVENTION AND TOXICS
U.S. ENVIRONMENTAL PROTECTION AGENCY
August 1994
Chemicals can be released to the environment as a result of their
manufacture, processing, and use. EPA has developed information
summaries on selected chemicals to describe how you might be exposed to
these chemicals, how exposure to them might affect you and the environ-
ment, what happens to them in the environment, who regulates them, and
whom to contact for additional information. EPA is committed to reducing
environmental releases of chemicals through source reduction and other
practices that reduce creation of pollutants.
WHAT IS CHLORINE, HOW IS IT USED, AND HOW MIGHT I BE EXPOSED?
Chlorine is a highly reactive gas. It is a naturally occurring
element. Chlorine is produced in very large amounts (23 billion pounds in
1992) by eighteen companies in the United States. US demand for chlorine
is expected to increase slightly over the next several years and then
decline. The expected decline in US demand is due to environmental
concerns for chlorinated organic chemicals. The largest users of chlorine
are companies that make ethylene dichloride and other chlorinated solvents,
polyvinyl chloride (PVC) resins, chlorofluorocarbons, and propylene oxide.
Paper companies use chlorine to bleach paper. Water and wastewater
treatment plants use chlorine to reduce water levels of microorganisms that
can spread disease to humans.
Exposure to chlorine can occur in the workplace or in the environment
following releases to air, water, or land. People who use laundry bleach
and swimming pool chemicals containing chlorine products are usually not
exposed to chlorine itself. Chlorine is generally found only in industrial
settings. Chlorine enters the body breathed in with contaminated air or
when consumed with contaminated food or water. It does not remain in the
body due to its reactivity.
WHAT HAPPENS TO CHLORINE IN THE ENVIRONMENT?
Chlorine dissolves when mixed with water. It can also escape from
water and enter air under certain conditions. Most direct releases of
chlorine to the environment are to air and to surface water. Once in air
or in water, chlorine reacts with other chemicals. It combines with
inorganic material in water.to form chloride salts. It combines with
organic material in water to form chlorinated organic chemicals. Because
of its reactivity chlorine is not likely to move through the ground and
enter groundwater. Plants and animals are not likely to store chlorine.
HOW DOES CHLORINE AFFECT HUMAN HEALTH AND THE ENVIRONMENT?
Effects of chlorine on human health and the environment depend on how
much chlorine is present and the length and frequency of exposure. Effects
also depend on the health of a person or condition of the environment when
http://www.epa.gov/opptintr/chcmfact/f_chlori.txt 12/20/2007

Page 2 of 2
exposure occurs.
Breathing small amounts of chlorine for short periods of time
adversely affects the human respiratory system. Effects range from
coughing and chest pain to water retention in the lungs. Chlorine
irritates the skin, the eyes, and the respiratory system. These effects
are not likely to occur at levels of chlorine that are normally found in
the environment.
Human health effects associated with breathing or otherwise consuming
small amounts of chlorine over long periods of time are not known. They
are currently under investigation. Some studies show that workers develop
adverse effects from repeat inhalation exposure to chlorine, but others do
not. Laboratory studies show that repeat exposure to chlorine in air can
adversely affect the immune system, the blood, the heart, and the
respiratory system of animals.
Chlorine causes environmental harm at low levels. Chlorine is
especially harmful to organisms living in water and in soil.

Hi Raj,
I just spoke with Jennifer in order to get a better understanding of the stormwater permit
process. This is a renewal of their current stormwater permit. They don't have many sampling
requirements at this time. Smith Creek, which is the creek that Spring Creek flow into is
currently impaired due to a sever biological rating (2003 rating). This is a swamp stream so their
discharge should not alter the natural conditions (pH or DO). 1 think that they should be required
to test for pH, BOD and total residual chlorine as well as other possible toxic chemicals that
could possibly end up in their stormwater. All of these can affect the biological community in
the receiving streams. 1 may suggest that ESS do a biological assessment closer to this facility in
the future. Please let me know if you have any questions.
Thanks
Nora
Hi again Narayan,
I forgot to add that Corning also releases a significant amount of Hydrochloric Acid - so I am
wondering if you are significantly concerned about low pH in this watershed? I believe low pH
is toxic to fish.
---------------------
Hi Narayan,
I am renewing a stormwater permit for Corning, Inc in Wilmington, NC. The stormwater from
the site drains to a UT to Spring Branch which then drains to Smith Creek. Smith creek is on
303(d) list and I see that a TMDL has been created for Smith Creek for 2008 and the lower Cape
fear has a TMDL under development for the lower Cape Fear. The distance from Corning to
Sprint; Branch is about 0.5-1 miles, and distance from Spring Branch to Smith Creek is about l
mile. The Stream index is 18-74-63-1 for the closest Spring Branch #. The lat is: 34 14' 54"N
and Long:77 52' 17.98"W.
Do you have any specific recommendations for this site re: Smith Creek's low DO and benthic
invertebrates problems? le do you have any parameters you would like monitored in the permit?
Do you have any concerns about this area besides the waste water treatment plant that was there,
that 1 believe was shut down?
They also have a permit to discharge in air, but a lot of roof space - consequently rainwater to
gutters and then to stormwater can be a problem. Here is the epa website that lists the chemicals
released into the air and by the ww: there seems to be quite a lot of chlorine which I think
maybe we should monitor for.
htty://oasijub.e_pa.gov/enviro/tris control.tris print?tris_id=28405CRNNG310NC
Please let me know if you have any thoughts/comments about this site and stream section.
Thank you for your help! Give me a call if you have any questions about this.
Thanks!
Jennifer

Subbasin 03-06-23 is in the coastal plain where many
streams stop flowing during summer months. Most of the
watershed is forested with some agriculture present and
increasing development. Development is occurring north
around Wilmington. Population is expected to grow by
140,000 people in counties with portions or ail of their
areas in this subbasin by 2020.
There are seven individual NPDES wastewater discharge
permits in this subbasin with a permitted flow of 3.8
MGD (Figure 26). The largest are Global Nuclear Fuels
(1.9 MGD) and Elementis Chromium (I MGD). Refer to
Appendix VI and Chapter 30 for more information on
NPDES permit holders. Issues related to compliance with
NPDES permit conditions are discussed below in Section
23.3 for Impaired waters.
There is one registered horse and 52 registered swine
operations in this Subbasin.
There were ten benthic community samples (Figure 26
and Table 26) collected during this assessment period.
Data were also collected from eight ambient monitoring
stations including two LCFRP (Appendix V) stations and
two DWQ ambient station and four shared stations. Two
reservoirs were also monitored. Refer to the 2003 Cape
Fear River Basinivide Assessment Report at http:Lvw.a_sb.ciir.st�te.ne.kis/bar.html and Appendix IV
for more information on monitoring.
Waters in the following sections are identified by assessment unit number (AU#). This number
is used to track defined segments in the water quality assessment database, 303(d) Impaired
waters list and the various tables in this basin plan. The assessment unit number is a subset of
the DWQ index number (classification identification number). A letter attached to the end of the
AU# indicates that the assessment is smaller than the DWQ index segment. No letter indicates
that the assessment unit and the DWQ index segment are the same.

23.3.3 Northeast Cape Fear River [AU#18-74-(47.5)]
Current Status and 2005 Recommendations
The Northeast Cape Fear River from Hwy 210 to Prince George Creek (15.6 miles) is Impaired
on a monitored basis in the fish consumption category and will be added to the 303(d) list of
Impaired waters.
23.3.4 Long Creek [AU#18-74-55a and b]
Current Statits
Long Creek was Fully Supporting in the 2000 basin plan; however, Long Creek [ 18-74-55a]
from source to Cypress Creek (7.7 miles) is currently Impaired for aquatic life because ofa
Severe benthic community rating at site 1313139. Long Creek is channelized and has poor habitat
conditions. The stream is affected by beaver dams. Conductivity was high at the sample site and
the benthic community was dominated by tolerant species.
Long Creek (I8-74-55b] from Cypress Creek to (21.5 miles) is Impaired oil a monitored basis in
the fish consumption category. No other data were collected in this segment.
2005 Recommendations
DWQ will continue to monitor the Long Creek watershed and evaluate impacts of NPDES
discharges into Long Creek. DWQ will contact DSWC to evaluate if agricultural BMPs can be
implemented to improve water quality.
Both segments will be added to the 303(d) list of Impaired waters. TMDLs (Chapter 35) will be
developed for identified stressors within 8-13 years of listing.

Hi Thom and Linda,
I am working on Corning's stormwater renewal permit (Wilmington
facility). I spoke to Jennifer Adams there today and I think you might
have done a site inspection/audit last year? I was wondering if I
could ask you a few questions about it.
I had a few questions (see below) and also some more since talking to
Jennifer at Corning. I was wondering what you think about their site?
Is it very clean, and did you see a lot of chemical storage - if so how
did that look to you? I believe they use methylene chloride which I
belive is toxic and also few acids. Did you see any evidence of that?
What do you think about them monitoring for pH? I also believe they
store waste outside - did you have a chance to see any of that?
How did their maintenance of their roads and their ponds look? I think
that they have a few parking lots - do you know what they are used for?
They said that they had not done any analytical stormwater monitoring -
do you know about this or anything different?
Also they said that some of their roof structure that comes off their
manufacturing building was "grandfathered".in and they therefore didn't
have to send it to a pond. I asked if they had a letter stating this
but she did not - do you know anything about this?

Hi Pat and Aisha,
I hope you both had a good Christmas and New Years. But now hack to
work... I am reviewing this individual permit for Corning's Stormwater
and I had some questions for you I hoped you could answer for me...
1) I think that you went on a site visit because of a complaint - was
there anything unusual there? I saw you noted in RIMS "A lot of algae
in the basin, heavily wooded vegetation has accumulated on basin walls,
overflow and bypass need to be checked to see that they are at correct
elevation". Do you have any ideas as to why there might be so much
algae? Do you think this is due to their design, waste water emissions
or...? Do you think their stormwater is contributing to this in any
way?
2) I noticed that there has been 2 increases in Tower 5, and 1 in the
parking lot - have you seen any other expansions?
3) It doesn't seem like they emit a lot of organics, Nitrogen or
Phosphorus - any comments? They emit a lot of chlorine and
hydrochloric acid through their stacks. One concern I have is that it
might be depositing on their roofs, and if rainwater is running off it
appears that it is directly going from the guttering to an outfall and
off the site - on what they are calling "exempt'.
4) Any other notes/commente/visits?
Thanks in advance for your help!

SUBJECT: Review of Dispersion Modeling Analysis for Corning, Inc.
Wilmington, NC New Hanover County
I have reviewed the dispersion modeling analysis, received June 8 and updated on June 21, 2006,
for the Corning, Inc. fiber optics manufacturing plant located in Wilmington, NC. The modeling
was conducted in order to demonstrate compliance with the AALs for several N.C. regulated
toxics that will be affected by proposed modifications at the plant. The modeling adequately
demonstrates compliance, on a source -by -source basis, for all toxics modeled.
Hydrogen fluoride and total fluoride are emitted from the facility and will be affected by the
modifications. Emission rates used in the modeling are provided in attached Table 1 and assumed
24 hours per day operation. Stack parameters are provided in Table 2.
ISCST3 using the latest available year (1991) of meteorological data from Wilmington (surface)
and Charleston, SC (upper air) was used to evaluate impacts in simple terrain; the facility is
located in a relatively flat area and elevated terrain was not evaluated. Direction -specific building
dimensions, determined using EPXs BPIF program (95086), were used as input to the model for
building wake effect determination. Receptors were placed around the facility at 25-meter
intervals and extended outward to a distance of 5 kilometers using a nested grid with 50, 100, and
500 meter spacing. SCREENS (96043) was used to evaluate cavity impacts at the facility;
however, cavity concentrations were zero so no further analysis was necessary. All toxic impacts
were well below their respective AALs and the percentages of their respective AALs are shown in
the following table,

production. Stack parameters for both scenarios are provided in Table 2.
ISCST3 using five years (1987-1991) of meteorological data from Wilmington (surface) and
Charleston, SC (upper air) was used to evaluate impacts in simple terrain; the facility is located
in a relatively flat area and elevated terrain was not evaluated. Direction -specific building

Introduction
The Corning incorporated facility in Wilmington has two (3) NPDES outfalls for non -
contact wastewater and stormwater, four (4) existing NPDES outfalls for stormwater only, and
eight (8) stormwater outfalls serving areas exempt from NPDES permitting. Attachment A contains
a table listing the estimated total drainage area acreage for the outfalls discussed in the next sections.
Outfall 001 SCC currently services a constructed stormwater pond (Pond 5), however, future
construction of a cooling tower system is listed in permit NC0003794, but is not currently constructed.
NPDES Permitted Outfalls
Outfalls 001, 002 and 001 SCC
NPDES Permit No. NCO003794 covers wastewater discharges from the facility via NPDES
Outfalls 001 and 002 (see Drawing labeled "Overall Sheet"). Outfalls 001 and 002
also discharge stormwater runoff from portions of the facility where chemical storage, loading
and unloading occur. Outfall 001 also receives stormwater runoff from a portion of the parking
area labeled Drainage Area 14, This drainage area is considered to be an exempt area since
it is only a parking lot (see Drawing Sheet labeled "Quad 3"). Outfall 001 has a
total drainage area of 2.24 acres. This total does not include the exempt Drainage Area 14.
Outfall 002 has a total drainage are of 9.78 acres with 6.81 acres being impervious.
Outfall 001 SCC has a total drainage area of approximately 30.35 acres, with 4.56 being impervious.
Outfalls 003, 004, 005, & 008
. Drainage Area 3 contains manufacturing assets not currently in use. The property is bounded
on the north, south and east largely by the property lines. See Drawing Sheet labeled "Quad 1"
and "Quad 4"). The total drainage area is 6.81 acres with 5.50 acres being impervious. Drainage
Area 3 discharges through Outfall 003 via a stormwater retention pond constructed in 1998.
Drainage Area 4 receives stormwater drainage from a portion of the Manufacturing Building
roof (see Drawing Sheet labeled "Quad 4"). All 2.12 acres of Drainage Area
4 are impervious. Drainage Area 4 discharges through Outfall 004, Also, exempt Drainage
Area 5D discharges through Outfall 004, Drainage Area 5D is 0.64 acres of impervious surface.
Drainage Areas 5A and 5B discharge to a stormwater retention pond located prior to Outfall
005. The retention pond was constructed in 1996. Drainage Area 5A contains 2.26 total acres
including 0,71 impervious acres. Drainage Area 5B is 6.14 acres with 4.53 acres impervious.
Two exempt drainage areas discharge through Outfall 005. Exempt Drainage Area 5C is
comprised of a manicured front lawn, with 2.21 total acres and 0.33 acres impervious. Exempt
Drainage Area 5D receives stormwater drainage from an administrative office building roof
(.84 acres impervious).
Drainage Area 16 discharges to a stormwater pond constructed in 2001. See Drawing
Sheet labeled "Quad 4". The drainage area consist of 6.81 acres, with 5.50 being impervious.
The drainage area consists of manufacturing support equipment, pollution abatement equipment
and cooling towers.
Outfalls Exempt from NPDES Permitting
Eight (8) outfalls are identified on the storm drain piping drawings as "Exempt
Outfalls (EO)". These outfalls receive water from areas containing no industrial activity and no
potential for stormwater contamination; therefore, these outfalls and corresponding drainage
area are exempt under NPDES regulations.

0 Drainage Areas Not Being Discharged through Outfalls
The remainder of the Corning Incorporated property, Drainage Area 6 and Drainage Area 9,
is completely pervious with no direct discharge points from the site, Drainage Area 6 is 0.49
acres and Drainage Area 9 is 10.22 acres.
Site Drainage Controls
The Wilmington plant system design standard requires storm drain systems to function during a
50-year storm event. The three (5) existing stormwater retention ponds meet the requirements of
NCDWQ State Stormwater Management Systems permit program.
All secondary containment systems located at the facility have been upgraded to retain the
capacity of the largest vessel plus a 24-hour125-year storm event (defined as 8 inches of rainfall
for the Wilmington area). The Stormwater Pollution Prevention Plan (SP3) includes keyed lockouts
of the drain systems. The Area SP3 team identified "appropriate testing" and record keeping
provisions during Best Management Practices (BMP) development. Collected stormwater from all
secondary containment systems is evaluated prior to making a determination to discharge any
collected stormwater to the outfalls. There is an alternate system available for the discharge of
contaminated stormwater. Collected stormwater can be redirected, if required due to contamination,
to the Pollution Abatement Process for pretreatment prior to discharge to the City of Wilmington WWTP.

• Best Management Practices
The Corning Incorporated facility in Wilmington relies on BMP's as well as engineered
structures to control stormwater and stormwater contamination. Following is a list of
some of the BMP's practiced at this facility.
1) Cooling tower chemicals stored in secondary containment
2) Diesel Fuel stored in secondary containment
3) Monthly testing of high level alarms in the sanitary lift stations
4) Raw materials are dispensed and waste materials are accumulated in an
enclosed building with diking and a floor sump
5) Waste drums are stored under cover in a sloped and diked area
6) Pollution abatement equipment is contained is secondary containment
7) Bulk raw materials are contained in secondary containment dikes
8) Stormwater accumulation in secondary containment dikes must be evaluated
before pumping to the outfall system. Water that fails criteria is sent to the
neutralization system and eventually to the POTW system.

Air Quality Impact Aaialpsis for the
w� Corn hi f ilmington T40Application, 911min ton, North Carolina
1.0 INTRODUCTION
Corning Incorporated is proposing to modify its operations at its fiber optics manufacturing plant in
ZD
-' Wilmington, North Carolina. Prior to commencing construction or modification of any air pollutant
emission source, Corning Incorporated must submit an "Application for Air Permit to
Construct/Operate" to the North Carolina Department of Environment, and Natural Resources
r' (NCDENR). As part of the' permit application process, the applicant must demonstrate that the
facility will comply with the North Carolina Air Toxic Standards. The modification Nvill affect the
facility's potential to emit of chlorine, hydrogen chloride, hydrogen fluoride, and total fluorides.
The potential for these pollutants to be emitted in quantities greater than the NCDENR toxic air
pollutant permitting emissions rates (TPERs) will remain after the modification. Because of these
changes, it was necessary to perform an Air Quality Impact Analysis (AQIA) to demonstrate
compliance with the AALs. This report presents the AQIA methodology and dispersion modeling
jresults that were used to estimate air quality impacts from the proposed project. The predicted
pollutant impacts of interest were evaluated with respect to the AALs as defined in the current North
Carolina Air Toxic Standards. There are no modifications to existing buildings/structures, additions
of any buildings or structures, or property boundary changes being made as part of the proposed
modification project.
Section 2.0 of this document presents both a description of the site and a description of the
pollutants/locations that require dispersion modeling for air toxic emissions. Section 3.0 presents the
methodologies that were used for dispersion modeling. Section 4.0 presents the dispersion modeling .
results for the five air emissions sources that were evaluated. Sections 5.0 and 6.0 present the
general analysis conclusions and references used; respectively. The modeling analysis has
conformed to the NCDENR Division ofEnvironmentdl Management's Guidelines for Evaluating the
Air uality Impacts of Toxic Pollutants in North Carolina (Reference 1), and the North Carolina
Tonics ModelingProtocol Checklist has been completed and is included in Appendix A.

2.0 SITE AND FACILITY REPRESENTATION
2.1 Site Representation
Corning Incorporated is proposing to modify a fiber optics manufacturing plant located in
Wilmington, North Carolina. The plant UTM coordinates are 235,741 E and 3,793,483 N at an
elevation of approximately 36.8 feet above mean sea level. The. plant is located at 310 North
College Road in New Hanover County. The property terrain is generally flat with a gentle
downward slope towards the seashore to the south and east. The terrain does not increase more than
I5 feet within three (3) kilometers (km) of the facility. Therefore, the terrain is considered to be
"simple" since the terrain within three (3) km of the facility is below the five stack heights to be
modeled. For dispersion modeling purposes, the terrain was treated as flat terrain. Furthermore, the
land use within three (3) km of the site can be characterized using the Auer technique (Reference 2)
as being rural. The overall facility site plan and the USGS topographic map, included in this
application (see Roof Diagram, Plant Layout, Plot Plan, and Area Map), show the site plan with
significant structures and site location for the project. The site survey/certified plat map for the
property can be found in Appendix E of this report.
2.2 Pollutant Characteristics and Locations
Physical site parameters such as the stack elevations and the controlling building dimensions were
obtained from facility layouts, plot plans, and existing source information consistent with
source/stack information provided in previous permit application packages. Stack exit velocities,
exit temperatures, and emission rates for the proposed expansion and modifications are consistent
with those provided in this permit application package.
The Corning Incorporated facility manufactures fiber optics. The manufacturing processes are
currently permitted to emit hydrogen chloride, chlorine, hydrogen fluorides, and fluorides .in
quantities greater than the TPERs. As shown in Table 1 at the end of this document, the only air
toxics which both exceed the trace emission values specified in the current North Carolina Air

Table 2 summarizes the emission source parameters for the five emission points that have been
modeled. Stack I is a standalone structure located on the northeast side of the main plant building.
Stack 2A is a standalone structure located on the northeast side of the main plant building. Stack 3 is
a standalone structure located on the southeast side of the main plant building. Stack 3 is a
standalone structure located on justnorth of the proposed expansion site of the property. Stack 6 is a
standalone structure located on the northeast side of the main plant building. Stacks 1, 2A, and 3
have the potential to emit chlorine, hydrogen chloride, hydrogen fluoride, and total fluorides. Stack
3 has the potential to emit chlorine and hydrogen chloride. Stack 6 has the potential to emit
hydrogen fluoride and total fluorides. All stack parameters, such as volumetric flaw rate, stack
diameter, stack exit velocity, stack height, was temperature and location, as well as parameter
i derivation have been defined and are consistent with the permit application package. Overall facility
site plans can be found in this application (Roof Diagram, Plant Layout, and Plot Plan).
Conversion of pollutants to other species, depletion and deposition were not considered in the
dispersion modeling.

SUBJECT: Review of Dispersion Modeling Analysis for Coming, Inc.
Wilmington, NC New Hanover County
I have reviewed the dispersion modeling analysis, received December 29, 2004, for the Corning,
Inc. fiber optics manufacturing plant located in Wilmington, NC. The modeling was conducted in
order to demonstrate compliance with,the AALs for several N.C. regulated toxics-that will be
affected by proposed modifications at the plant. The modeling adequately demonstrates
compliance, on a source -by -source basis, for all toxics modeled.
Several toxics including chlorine, hydrogen chloride, hydrogen fluoride, and total fluoride are
emitted from the facility and will be affected by the modifications. Emission rates used in the
modeling are provided in attached Table 1 for two different flow scenarios, depending upon
production. Stack parameters for both scenarios are provided in Table 2.
ISCST3 using five years (1987-1991) of meteorological data from Wilmington (surface) and
Charleston, SC (upper air) was used to evaluate impacts in simple terrain; the facility is located
in a relatively flat area and elevated terrain was not evaluated. Direction -specific building
dimensions, determined using EPA's BPIF program (95086), were used as input to the model for
building wake effect determination. Receptors were placed around the facility at 25-meter
intervals and extended outward to a distance of 5 kilometers using a nested grid with 50, 100,
and 500 meter spacing. SCREEN3 (96043) was used to evaluate cavity impacts at the facility;
however, cavity concentrations were zero so no further analysis was necessary. All toxic impacts
were well below their respective AALs and the percentages of their respective AALs are shown
in the following table.

FROM: Tom Andersoneteorologist, AQAB
THROUGH: un Roller, Supervisor, Air Quality Analysis Branch (AQAB)
SUBJECT: Review of Dispersion Modeling Analysis for Corning, Inc.
Wilmington, NC New Hanover County
I have reviewed the dispersion modeling analysis, received June 8 and updated on June 21, 2006,
for the Corning, Inc. fiber optics manufacturing plant located in Wilmington, NC. The modeling
was conducted in order to demonstrate compliance with the AALs for several N.C. regulated
toxics that will be affected by proposed modifications at the plant. The modeling adequately
demonstrates compliance, on a source -by -source basis, for all toxics modeled.
Hydrogen fluoride and total fluoride are emitted from the facility and will be affected by the
modifications. Emission rates used in the modeling are provided in attached Table 1 and assumed
24 hours per'day operation. Stack parameters are provided in Table 2.
ISCST3 using the latest available year (1991) of meteorological data from Wilmington (surface)
and Charleston, SC (upper air) was used to evaluate impacts in simple terrain; the facility is .
located in a relatively flat area and elevated terrain was not evaluated. Direction -specific building
dimensions, determined using EPA's BPIF program (95086), were used as input to the model for
building wake effect determination. Receptors were placed around the facility at 25-meter
intervals and extended outward to a distance'of 5 kilometers using a nested grid with 50, 100, and
50.0 meter spacing. SCREEN3 (96043) was used to evaluate cavity impacts at the facility;.
however, cavity concentrations were zero so no further analysis was necessary. All toxic impacts
were well below their respective AALs and the percentages of their respective AALs are shown in
the following table.
