The draft permit looks good to me except for a misspelled word on pages
A 1, A2, and A3 in the statement concerning the use of Biocides. It
should probably say "utilizing".

BACKGROUND
Corning Inc.'s Wilmington Plant manufactures optical waveguide fibers. Process and contact
wastewater is sent to the City of Wilmington's wastewater treatment facilities; the subject permit only
covers non -contact cooling water, boiler blowdown, air conditioner condensate, air compressor cooling
water, roof/yard drainage, bleed -off from wells and stormwater. These discharges were covered under a
general permit originally, but were covered under an individual permit beginning in 1981 as per a request
made by the Wilmington Regional Office (WiRO),
Outfall 001 discharges non -contact cooling water and other non -process wastewater; outfall 002
discharges non -contact cooling water, non -process wastewaters and stormwater. Biocides and other
water treatment chemicals have been added to each of these wastestreams. The permit renewal
application proposes a new outfall, 001SCC (as per Corning's on -site naming convention) for the
discharge of non -contact cooling water and heat exchanger water that is expected to be identical in nature
to the discharge from 001.
The Permittee also holds Stormwater Permit NCS000076 and a permit associated with the Coastal
Stormwater Program.
Instream Monitoring and Verification of Existing Conditions and DMR Data Review.
DMR data from January 1999-July 2001 were reviewed. The facility monitors flow,
temperature, pH and total residual chlorine. At outfall 001, the average flow was 0.0240 MGD and the
average TRC was 4.7 ug/L. At outfall 002, the average flow was 0.053 MGD and the average TRC was
6.4 ug/L.
Upstream and downstream temperature is recorded weekly. In general, there appears to be little
difference between the upstream and downstream temperature (see instream data plot attached to
document).
Fact Shoo[
NF DE.S iNC;000,3794 Rcnow:il
1'art� l

The facility is described by the Regional Office as being very well maintained and in keeping
with the requirements of all relevant permits.
PERMITTING STRATEGY
The proposed new outfall, 001 SCC, should have the same conditions as 001. For purposes of
entering it into our database, the outfall will be designated 003 (Coring's 001 SCC). The Supplement to
the Cover Page should state that the monitored parameters are contingent upon the same or equivalent
cooling towers and HVAC being installed as what is already on site.
Waste Load Allocation (WLA).
The last WLA was done in 1985 and recommends monitoring for pH and temperature.
Reasonable Potential Analysis (RPA).
Given the effluent characteristics (no process wastewater) and monitoring requirements, no
reasonable potential analysis was performed.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies, the permit will remain the same for the existing outfalls 001
and 002. A new outfall, 003 (Coming's 001SCC), will be added to the permit with monitoring
requirements identical to those of 001.

S. other Special Items:
PART TV - EVALUATION AND RECOMMMDATIONS
The company produces waveguide fibers which are used for
telecomnunications and data, transmissions. Sanitary waste and
contact waste are discharged to the City of Wilmington collection
system. Outfall, 001 includes non -contact blowdown from Cooling
towers 1 - 5, air conditioning- condensate, air compressor cooling
water, and bleed -off from well #2. dutfall 002 includes blowdown
from. Cooling towers #6, 7, 8, 11, and 12, air conditioning
condensate, stormwater, roof drainage and yard drainage, bleed off
from wells 43, 4, and 5, and hvz idification boiler blowdown,.
Stornwater is included in each of the outfalls ' also. The
application identifies the drainage areas for each outfall.
Biocides and conditioners added to the cooling towers and boilers
have been previously approved through review of biocide worksheets.
The biocide and conditioner program for the cooling towers is
electronically controlled using sensors and timers to avoid
b?owdown during periods of chemical application. A product is then
introduced to remove the oxidizer prior to discharge. A backup
Carron filtratLon system Nis in place for removal of oxidizer in the
event that the feed system does not operate properly. Band testing
is done routinely and the carbon filter system is tested monthly
and carbon is replaced as required. The discharged water appears
veer Clear and free of solids. The outlet structures oonsist of
sediment baeins and weir plates with staff gages for flow
measureme*xt . .
The facility also holds Stomnwater permit No. NCS000076 and a
permit associated with the Coastal. Stormwater program. Some of the
permitted outfall.s in the Stormwater NPDES Permit are also
associated with the Coastal Stormwater Permit. The company does a
good job of meeting the requirements of each permit. Teams of
employees have been given responsibility for specific drainage
areas within the plant site that are associated with identified
stormwater outfalls. A plan has been developed as required by the

DEC. 7.2001 1',16PM NCDENR WIRO NO.716 P.5
permit, BMPs are in place, and records are kept of obsex-trations.
The writer recommended in the past that the stormwater permit be
incozporated into the cooling water permit. Because of the
complexity of the stormwater NPDBS permit and the different dates
for raissuance, it is now recommended that the permits not be
incorporated.
The company requests that an additional cooling water outfall,
0019CC, be added to support plans for future expansion.. Plans for
expansion are uncertain at the present but may resume if the
economy improves. it =s recommended that the additional outfall be
added as requested. It is recommended that a permit be drafted
containing existing limits and monitoring requirements for outfalls
001 and 002 and the addition of outfall 001SCC.' If no significant
adverse public Comments are received, it is recommended that the
permit be reissued for a period of five years, consistent with the
basinwid.e permitting program.

Corning, Inc. -- Wilmington Plant PAINT 50URCE BRANCH
New Hanover County
CORNING Dear Mr. Goodrich:
Dkaa ring Beyond Imagi"6on
Enclosed please find one original and one copy of the referenced application. Each
document contains the following information;
• Standard Form C RECEIVED
• Operating status description
WATER QUA!M'SCC710N
• 5 year operating projection
• Wastewater flow schematic 2Epu,
• Water Supply Use & Disposal Worksheet
• Maps; - Outfall location map Ncn•Ciischarge pr n;tli,Tg
- Overall storm -drain piping layout & Quad maps
- Hazardous materials location map
• Cooling tower chemical additive MSDS sheets
Because all of the discharges from the facility are either stormwater or "non -contact
cooling water" confidential production data for the facility is not being submitted (per
conversations with Natale Sierra NCDENR, DWQ, NPDES-Group 6/7/01).
Should you have questions, or require further information with regards to this application,
please contact Alice Anderson at; [phone] ([e-mail]) or if
unavailable, Brad Newland at; [phone] ([e-mail]). Thank you
for your time and effort regarding this renewal request.
Sincerely,

Appendix A
Present Operating Status
There are no wastewater treatment system components installed at the Corning Incorporated -
Wilmington facility which are used to treat wastewater associated with the discharges permitted
under this permit NC0003794. All discharges associated with the outfalls permitted in this permit
consist of non -contact, non -process discharges which do not require treatment. All process
wastewaters are discharged from the facility via a treatment system to the City of Wilmington
POTW.

Appendix B
Potential Facility Changes
Corning Incorporated anticipates continuing business growth over the next five (5) years whi&
could require modifications at the Wilmington facility. Currently underway are modifications
of various process sources at the facility which impact the NPDES Permit NC0003794. These
impacts include the proposed creation of another discharge point (DSN001 SCC) to support
new sources of cooling tower and condensate blowdown. Appropriate construction permits
will be secured prior to creation of the new outfall (DSN001 SCC),
