herewith a modification to the subject permit.
Enclosed please find the modified effluent limitation pages. These pages should be
inserted into your permit and the old ones discarded. This permit modification is issued
pursuant to the requirements of North Carolina General Statute 143-215.1 and the
Memorandum of Agreement between North Carolina and the U. S. Environmental Protection
Agency dated December 6,1983.
Please take notice that this permit is not transferable. Part II, E.4. addresses the
requirements to be followed in case of change in ownership or control of this discharge.
This permit does not affect the legal requirement to obtain other permits which may
be required by the Division of Water Quality or permits required by the Division of Land
Resources, Coastal Area Management Act or any other Federal or Local government permit
that may be required.
If any parts, measurement frequencies or sampling requirements contained in this
permit modification are unacceptable to you, you have the right to an adjudicatory hearing
upon written request within thirty (30) days following receipt of this letter. This request must

Dear Mr. Goodrich:
CORNING
Corning, Inc., Concord Plant is making preparations for a maintenance shutdown period
the week of December 18, 2000. Part of the activities during this period will be the
draining and flushing of the non -contact cooling water basin. This is accomplished to
prevent malfunctions of the non -contact cooling water pumping system. The basin holds
60,000 gallons of water. 40,000 gallons of water from our FireWater Tank would be
used to flush the basin.
We are currently permitted to discharge non -contact cooling tower blowdown from
normal operations to Outfall 003. Outfall 003 also permits the discharge of our industrial
wastewater. The time established to drain and flush the non -contact cooling water basin
is six (6) hours, followed by another six (6) hours to refill the basin. This twelve- (12)
hour time period is necessary to reduce the down time of our HVAC system. Process
equipment that generates heat in the production area will still be running during this time.
Without the HVAC system operational, the heat generated by this equipment will shut
down portions of the computer system of the plant. Based on this short shutdown
duration and the current capacity of our pumping system for Outfall 003, it is not possible
to discharge this water through Outfall 003.
The proposed plan is to discontinue the addition of any additives to the non -contact
cooling water at a time prior to draining the basin to allow the additives to degrade
(please see attached recommendations from our supplier, BetzDearborn). We will
monitor pH and total residual chlorine.
We would like to discharge the 100,000 gallons (includes flush from the FireWater Tank)
to Outfall 002. Outfall 002 is designed as a detention pond. Our current permit allows us
to discharge stormwater and humidification boiler blowdown to Outfall 002. We are
currently required to monitor flow, temperature and total residual chlorine on a semi-
annually basis at Outfall 002.
This discharge will be an annual occurrence in the future during our maintenance
shutdown operations. These shutdowns occur at the end of each year (usually prior to the
Christmas holidays). As we expand, adding more cooling towers, the flow may increase.
We are requesting a modification to our current permit, in the form of a Special
Condition, to allow the annual discharge of the non -contact cooling water basin and
associated flush water to Outfall 002. We propose to suspend the use of water treatment
chemical feed as suggested by BetzDearborn prior to discharge.
Based upon the time usually required for a permit modification to be issued and the short
lead time we have for the 2000 shutdown, we are requesting initial approval for this
year's process as soon as possible. I apologize for the inconvenience of this short notice.
Please feel free to contact me if you have any questions or require further information. I
can be reached at phone number (704) 569-6268

RE: HVAC Cooling Tower Shutdown
Bill:
cc: Tom Hall

We have been asked to present to Corning an operating procedure to suspend the water
treatment chemical feed to the HVAC Cooling Tower to allow for direct discharge into
the holding ponds during the December shutdown. Currently BetzDearborn is supplying
the following chemicals to Cooling Tower system:
> BetzDearborn Spectrus OX1200-Biocide/Chlorine residual
> BetzDearborn Spectrus BD152-Biosurfactant/No detectable residual
> BetzDearborn Dianodic DN300-Corrosion Inhibitor/Ortho-phosphate residual
> BetzDearborn AF740-Antifoam/No detectable residual
> BetzDearborn Depositrol PY505-Polymeric Dispersant/No detectable residual
Fed to the Cooling Tower makeup water:
>, BetzDearborn F1oGard MS6206-Process Water Corrosion Inhibitor/O-PO4 residual
These chemicals are fed to the tower at a specific dosage based on a function of the
amount of water that is being bled from the system. The chemicals become concentrated
within the tower as a result of cycling. In order to reduce the concentrations of these
chemicals within the tower and allow for the water to be deemed acceptable under your
permit restrictions the feeds of the water treatment products will need to be suspended
prior to shutdown. In order to help dissipate residuals the tower blowdown rates should
be increased during the days leading up to the shutdown. We recommend the following
schedule:
1. 4 Days before shutdown- decrease cycles of concentration by 50%. This tower is
designed to run at 5 cycles. Increase blowdown to lower this level to no more than 3
cycles. Stop Spectrus BD152 and Depositrol PY505 feeds at this time. The lower
cycles will decrease the demand for each of these products.
2. 3 Days before shutdown- stop Dianodic DN300 feed at the tower and the feed of the
FloGard MS6206 at the Industrial Process Water Makeup. This will allow the
Phosphate residual to dissipate completely prior to discharge to the ponds. Continue
running at less than 3 cycles of concentration.
3. 2 Days before shutdown- stop Spectrus OX1200 feed and AF740 feed at the Tower.
The chlorine residual should be 0.0 PPM without the feed of this product.
4. 1 Day before shutdown and day of- the effluent from the Cooling Tower should be
closely monitored by the Plant personnel to assure the chlorine residual and the
phosphate residuals are below the permit specifications. Total suspended solids
should also be closely watched. At first indication of any permit excess, the flow
should be suspended to the ponds.
❖ The feed of the FloGard MS6206 should be resumed as soon as the HVAC Tower
stops receiving makeup water flow.
Due to variations in operating loads and seasonal temperature changes it is difficult to
accurately quantify the amount of water that will need to be bled to achieve our desired
operating conditions. These rates can be estimated using the following formulas.
Slowdown (GPM)= Evaporation Rate (GPM)
Cycles of Concentration —1
Evaporation (GPM) = iT(°F) * Recirculation Rate (GPM)
1,000
In summary, by increasing the tower blowdown rates and stopping the feed of the water
treatment chemicals days before the shutdown, the water within the system at the time of
the shutdown should be of the same chemical composition as the city water makeup.
This will be verified by real time chemical monitoring by Plant personnel.
We do not foresee any problems with the short-term suspension of water treatment
chemicals during this time period.
Thank you for allowing BetzDearborn to provide this recommendation to Corning
Incorporated. Should you have any questions concerning this report please do not
hesitate to contact me. I can be reached at 1-888-716-6198.
