discharges. The certification statement will be signed in accordance with the requirements found
in Part III, Standard Conditions, Section B.11.
b. Stormwater Management Plan: The stormwater management plan shall contain a narrative description of
the materials management practices employed which control or minimize the exposure of significant
materials to stormwater, including structural and non-structural measures. The stormwater
management plan, at a minimum, shall incorporate the following:
(1) A study addressing the technical and economic feasibility of changing the methods of operations
and/or storage practices to eliminate or reduce exposure of materials and processes to
stormwater. Wherever practicable the permittee should consider covering storage areas, material
handling operations, manufacturing or fueling operations to prevent materials exposure to
stormwater. In areas where elimination of exposure is not practicable, the stormwater
management plan shall document the feasibility of diverting the stormwater runoff away from
areas of potential contamination.
(2) A schedule to provide secondary containment for bulk storage of liquid materials, storage of
Section 313 of Title III of the Superfund Amendments and Reauthorization Act (SARA) water
priority chemicals, or storage of hazardous materials to prevent leaks and spills from
contaminating stormwater runoff. If the secondary containment devices are connected directly to
stormwater conveyance systems, the connection shall be controlled by manually activated valves
or other similar devices (which shall be secured with a locking mechanism) and any stormwater
that accumulates in the containment area shall be at a minimum visually observed prior to
release of the accumulated stormwater. Accumulated stormwater shall be released if found to be
uncontaminated. Records documenting the individual making the observation, the description of
the accumulated stormwater and the date and time of the release shall be kept for a period of five
years.
(3) A narrative description of Best Management Practices (BMPs) to be considered such as, but not
limited to, oil and grease separation, debris control, vegetative filter strips, infiltration and
stormwater detention or retention,where necessary. The need for structural BMPs shall be based
on the assessment of potential of sources contributing significant quantities of pollutants to
stormwater discharges and data collected through monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be taken to limit
or prevent erosion associated with the stormwater systems.

NC0086169

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

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

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

Minor Modification Request
Dear Mr. Goodrich:
CORNING
Discovering Beyond Imagination As discussed previously in our modification request, Corning Inc. has
decided to "mothball"the Concord Plant. "Mothball" means that there will
(Ae/,a ) be no optical fiber manufactured on site and the site will be "chemical
/ free". There will be no process chemicals required for optical fiber
CAn ispo manufacturing and all systems (equipment and piping) will be purged. As
1 J a condition of the mothballing, Corning Inc. has decided to maintain the
7b So^,e a.t. 1A facility in a state such that it can produce fiber within 6 months if the
business conditions change (within the next 4 years).
,n.,t .f
Ce. a 7(okt . With this directive, it will be necessary to maintain HVAC capability to
condition the building to minimized deterioration of equipment and
systems. Therefore, the current HVAC system(cooling towers)will need
/ 0`'r to operate during"mothball" status. The Concord Plant is currently
permitted to discharge non-contact cooling tower blowdown to Outfall 003
with our pollution abatement process water. During shutdown, the
pollution abatement system will not be needed. Therefore, there will be no
w,Y" " a` need to operate the current wastewater treatment system and no discharge
c Q c c,74- through Outfall 003. However, we intend to continue to keep the currently
6a 14 /7. required records and submit the appropriate reports to maintain our permit
as is.
Gdr c J0
/ Our permit modification, dated December 13, 2002, allows non-contact
cooling tower blowdown generated during the "mothball" status to be
\�� discharged through Outfall 002 untreated.
Based on this modification and that our current wastewater treatment
�° ,� system will be shutdown (locked out and tagged out)until such time as we
11
�(1; UJ�

•
restart the fiber making process, we are requesting that our current facility
classification,Grade II Chemical/Physical, be modified to a Class "0" or
unrated. An unrated facility does not require an Operator in Responsible
Charge. We are asking that the Permitting Section and the Regional
Office provide written agreement with this request such that we can
formally make the request of the Technical Assistance and
Certification Unit.
Please feel free to contact me if you have any questions concerning the
information presented. I can be reached at [phone].

Also,can you look at BOC's non-contact cooling water discharge permit. They discharge downstream of
our Outfall 001 into the same"dry"ditch we would discharge to.

>>>>>CT-Is 002 the only discharge point? Outfalls 001,002 and 003 are all options.
>>>>>CT-Is it okay to go through the storm-drain to get there on a continuous basis? That is an
option. Any monitoring required by DWQ would have to occur prior to the discharge reaching the storm
water system.
>>>>>Re-Qual-Lab status Lab certification will depend on what monitoring requirements are required
by DWQ,based on the discharge option we choose.
>>>>>Permit-calibrations if no discharge through lift station I recommend that all instrumentation be
up to date on calibrations and a memo to file be written regarding last calibration,last day of operation and
need for recalibration prior to start up. I will verify this with DWQ.
>>>>>Permit-Renewal/change back I recommend we maintain our current permit to discharge PA
water. This would mean renewing the NPDES permit next year. The reason for this is that to meet the 6-9
month restart requirement,we need an active permit. A new permit will take at least 180 days(has been
longer the last 2 times we requested a modification)and new regulations/regulators would make it difficult
to receive a permit as flexible as the one we have. (Corp Env.has concurred with this.)
>>>>>Storm water restrictions-if no chemicals or production,can dikes overflow or go automatically
to ground? If no chemicals are stored/used in the dike area,documentation should be kept as to the date the

chemicals were removed(and lines flushed). Then rainwater in the dikes can be automatically sent to the
ground.
>>>>>Permit-If zero process flow,what about sampling requirements? DWQ will have to provide
these requirements based on the discharge options we adopt.
>>>>>Permit-What about testing requirements,like toxicity? See above.
>>>>>CT-Is it okay to bypass filters? What types of changes would there need to be?-THIS MAY
BE A FACILITIES QUESTION OR A QUESTION WE DONT WANT TO ANSWER. See above.
>>>>>Permit-How long would it be until the final requirements(after the permit change)would be
known? Modifications could take as long as 180 days. We are working closely with DWQ to achieve a
workable solution as quickly as possible.
>>>>>Can we use CT for irrigation? Would landscaping be maintained during mothball? Corp.
Environmental policy is"no" discharge of any kind to the ground.
>>>>>If an ORC is required,what grade is necessary? See permit comments above.>

>>>>> Here are a few questions that I have:
»»>
>>>>> * Will the annual scrubber maintenance still be required even though there are no
emissions? 2002 control device inspections and maintenance will be required per our existing permit and
the manufacturers'requirements. Documentation will be required to indicate the last inspection(2002)and
the last day of operation of the control devices. All control devices should be inspected prior to start up.>
>>>>> * Will the stack emissions still need to be read on the same frequency even though there
are no emissions? Stack visible emissions should be documented as no emissions,no production on the
existing frequency. As with the NPDES permit,I recommend we maintain the existing Title V permit and
the requirements there in. It could be difficult to get as agreeable a permit as we now have if there is a
change in regulations(non-attainment,new control device technology)or regulators. Again,the 6-9 month
start up has to be considered.>
>>>>> * Will an ORC be required to be on site every day(M-F)if we are not discharging via the
Lift Station? This will depend on the option we choose and the requirements of DWQ.
>>>>> * Will cooling tower blowdown be able to be discharged to the retention ponds? This is a
viable option,however,we will have to discuss with DWQ and review their monitoring/reporting
requirements for this option.>
»»>
>>>>> I'm sure that both of you have thought of these and many others. Please make sure that any
questions that affect the long-term mothball state are answered as clearly as possible. These answers will
affect the things we do to get to the mothball state. Thanks.
