Dear Ms. Adams:
Based on the inspection conducted on October 17, 2008 at the Corning Incorporated facility and with
the cooperation of the Division of Water Quality Stormwater Permitting Unit in Raleigh, the Wilmington
Regional Office has determined that Outfall 008 can be represented at Outfall 003. All other outfalls
shall be monitored in accordance with the requirements specified in your Stormwater Permit
(NCS000076). Monitoring data collected throughout this upcoming permit cycle can be re-evaluated
upon the next permit renewal request to determine whether additional representative outfall status can
be granted.
Thank you for your patience in this matter. Should you have any questions concerning this report, you
may contact me at the letterhead contact information or via email at lindo,[e-mail]
Sincerely,

Enclosed please find the attached report for the Corning Incorporated, Wilmington facility,
for the stormwater discharge sampling taken on 4/09/15. This represents the semi-annual
monitoring period of (November 1, 2014 — April 30, 2015).
During that representative storm event, Outfall 004 and Outfall 005 were discharging while
003 was no -flow for the period. Analytical data for Outfall 001 and Outfall 002 were
submitted in a separate report on 03/20/15. Outfall 008 has representative outfall status
granted, so analytical monitoring was not completed for that specific outfall. All data was
collected using DWQ approved methods. If you have any questions concerning this

Inspection Date: 10/17/2008 Inspection Type: Compliance Evaluation Roason for Visit: Routine
Inspection Summary:
This inspection was conducted pursuant to the written request from Corning, Incorporated (September 25, 2008) to allow
representative outfall status for outfalls 001,003,004,005, and 008 at outfall 002. A review of the site plan and activities
within each drainage area contributing stormwater to all 6 outfalls was conducted. The Wilmington Regional Office
suggests that outfalls 004 and 008 be eliminated from the monitoring requirements due to the following:
004: Originally -included because of the impervious surface from the manufacturing building. WIRO feels this outfall can
be represented at 003 (which has more impervious surface) and includes roof runoff from manufacturing facility. After
consultation with the Central Office, WiRO will agree that monitoring requirements for 004 will remain for one permit cycle,
after which data will be reviewed for consideration as representative through outfall 003,
008: Originally included to capture quality of runoff from the impervious surface area near the manufacturing building.
This can be demonstrated at outfall 003 as well.
WiRO supports monitoring requirements at 001, 002, 003, 004 and 005 for at least one full permit cycle.
There were no issues of concern noted during the inspection. All outfalls were observed, the stormwater pollution
prevention plan will be updated to include the monitoring requirements specified in the renewed permit,

Hey Linda,
I am a little hesitant because they only have 1 sample which is not a good sample size. I am inclined to ask for 3 to 4 samples at least
If any, 008 could probably be taken out, however, I think that 004 should be loft In the monitoring. I included 004 because:
t) it has industrial root areal
2) we don't have a lot of data on stormwater runoff from dapoutlon In NC,
3) 1 think it is important that we get some data on these types of runoff.
4) 1 would especially like to see their& no they have a LOT of acids. NOX, and Cl Coming out of their stacks.
5) We only have 1 sample for this to I would hike to see a N0 5 years if possible of monitoring for this outfall, but if not possible at least 4 monitoring aarttples. That would be 2
yearsl2 full seasons of data. I am not sure it this is statistically significant • we have been told 5 ants that seems reasonable because rl-1 a3 does not seem too large of a sample set
to reasonably delete.
One of the things I was going 10 try to get was to develop a standard statistical method for monitoring • I.e.1$ of outfalls, - am stiii working on that have not had much response from
NCSl1.,, but will not give up on that one:)
In the mean•tlme I don't think we have statisfleal grounds to delete this outfall. I would respectfully request that we leave outfall 004 In. I think It Is an Important outfall.
Thank you for considering my opinion in this matter Lindal Please give me a call if you would like to discuss further.

Wilmington. NC 28405
'this letter is written as a request to allow representative outfall status (ROS) for the analytical
monitoring requirements of the aforementioned stormwater permit. This request includes maps,
numbered drainage areas, numbered outfalls, and a description of which outfalls Corning is
requesting ROS for which specific basins. Analytical monitoring results from a recent
Representative Storm Event are included as supporting data.
Ifyou have questions or comments about this request, please contact Jennifer Adams at (910) 784-
6498 or adamsjhncorning.com. Thank you very much.

Site Drainage Controls
The Corning Incorporated facility in Wilmington has two (2) NPDES outfalls for non -contact
wastewater and stormwater and four (4) NPDES outfalls for stormwater only. Table I contains a
listing of each outfall and specific drainage areas, which are shown on the following drawings:
013556-115571-EP W"A
013556-115581-I P 4013556-115591-I:P 013556-I15601-I.P0D i�013556-115611-I:P e,5t
Outfalls 0011 and 002
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 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, 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 (not including exempt area
14), which is all impervious. Outfall 002 has a total drainage area of9.78 acres with 6.81 acres
being impervious.
Outfalls 003, 00 '005
and 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 I" 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. \ 3
Drainage Area 4 receives stormwater drainage,f om a portion of the Manufacturing Building roof
(see Drawing Sheet labeled "Quad 4"). All 2, l2 �icres of Drainage Area 4 are impervious and
discharges through Outfall 004.
Drainage Areas 5A and 5B discharge to a stormwater retention pond located prior to Outfall 005.
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 (see Drawing Sheet labeled "Quad 3" and "Quad 4"). Two
exempt drainage areas discharge through Outfall 005. Exempt area 5C is comprised of ii
manicured front lawn, with 2.21 total acres and 0.33 acres impervious. Exempt area 5D receives
stormwater drainage from an admin building roof and is 0.64 acres impervious.
Drainage Area 16 discharges to a stormwater retention pond located prior to Outfall 008. 'rile
drainage area consists of 6.81 acres with 5.50 being impervious (see Drawing Sheet labeled "Quad
4"). The drainage area consists of manufacturing support equipment, pollution abatement
. equipment, and cooling towers.

Representative Outfall Status is being requested of Outfall 002, as being the most conservative and
an adequate representation of all 6 outfalls. This is the largest drainage area, receiving stormwater
runoff from both impervious and manufacturing areas. ResUItS or analytical monitoring taken
during a Representative Storm Event are summarized below and are significantly below benchmark
values and in some cases, non -detect levels (data previously submitted to DWQ as part orsemi-
annual reporting requirements):

Discussions with permittee: Jennifer Adams, Discussion 1 on January 3,
2008
1. Is the legal name and owner of the facility still Corning
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.* - Sent via
email 113108.
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.
Clarification - State NPDES Permit NCO003794 requires
i. OutfalI 001 - monthly flow, temp, pH, total residual
chlorine
ii. Outfall 002 - monthly flow, temp, pH, total residual
chlorine; quarterly total nitrogen & total phosphorus
iii. Outfall 003 (Corning OutfaIl 001SCC) - monthly flow,
temp, pH, Coral residual. chlorine ONCE CONSTRUCTED.
Construction has never started, nor are there any plans
to.
List of outfalls:
1. Outfalls 001, 002 (monitored in state Waste Water permit - NC0003794)
2. Outfall 001:
a. Chemical storage, loading and unloading - All outside, GP&I. is
waste storage and them storage areas are
covered or double contained.
b. Outfall 001 receives from parking drainage area 14, lift
station overflow, parking area, water tank, water well,
treatment chemicals
c.
88-I----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&U transmission substation, diesel fuel storage
3. Pond 2 is exempt outfall - #E04A
a. *Ms. Adams - Please clarify as to why exempt. Please email
back.
b. Clarification - Pond 2 discharges to outfall EO-4, exempt
since area contains no industrial activity. Pond emergency
overflow is labeled as outfall EO-4A
4. 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, via underground pipe - discharge is at
southeast corner.
iii. Pond 3 is being used to collect stormwater, but
manufacturing area 3 is not. ????
b. Outfall 004: Permitted outfall.
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./ Clarification - area 5D
not exempt, drains through outfall 005, via Pond 1
c. Outfall 005:
i. 5A and 5B drain to Pond 1 in quad 3 then to 005. Areas SA,
5B, 5C, and 5D drain to Pond 1, discharge via outfall 005.
ii. /Pow 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
i. Area 16 is the entire area surrounding pond 4 - all goes to
Pond 4, and then discharges out 008.
ii. Drains area 16: support equipment, pollution
abatement equipment and cooling towers.
5. Why is 5D exempt and other roof structure draining to 004 is not
exempt? - See clarification above - area not exempt.
6. 4 and 4a were "grandfathered" (We need to clarify this point as we
do not usually accept this term for stormwater permitting].
Clarification - area 4 receives stormwater draining from a portion
of the manufacturing building roof. Drains to permitted outfall
004. Area 4A also receives stormwater from the building roof, but
from an area without industrial activity, therefore exempt from
NPDES regulations, draining to outfall EO-6. Both are
"grandfathered from Pond requirements.

7. Area 5A and 3 appear to be linked by outfalls/drains. //
Clarification - not linked, just next to each ocher. Drainage
system is separate.
