Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
Z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
° See General Permit, Section B, Table 1 to identify the especially sensitive receiving water classifications where the more protective benchmark applies.
s Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

All permits require qualitative monitoring to be performed during a "measurable storm event"
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 DWQ Regional Office.

3. Odor: Describe any distinct odors that the discharge may have (i.e., smells strongly of oil,
weak chlorine odor, etc.): No odor was present.
4. Clarity: Choose the number which best describes the clarity of the discharge, where 1 is
clear and 5 is very cloudy:
1 Q2 3 4 5
5. Floating Solids: Choose the number which best describes the amount of Floating solids in
the stormwater discharge, where 1 is no solids and 5 is the surface covered with Floating solids:

6. Suspended Solids: Choose the number which best describes the amount of suspended
solids in the stormwater discharge, where 1 is no solids and 5 is extremely muddy:
1 22 3 4 5
7. Is there any foam in the stormwater discharge? Yes No
8. Is there an oil sheen in the stormwater discharge? Yes No
9. Is there evidence of erosion or deposition at the outfall? Yes No
10. Other Obvious Indicators of Stormwater Pollution: None
List and describe: SDO #1 is represented by SDO U. The discharge contained visible rock dust
from the adjacent rock quarry.
Note: Low clarity, high solids, and/or the presence of foam, oil sheen, or erosion/deposition

Please find enclosed an original and one (1) copy of the Stormwater Discharge Monitoring
Report for Corning Optical Communications, LLC — Hickory Manufacturing and Technology
Center (HMTC) located in Hickory, Catawba County, North Carolina. The stormwater
samples were collected on 10/08/2019 for the permitted outfalls and represent the monthly
sample as specified in the requirements set forth by NCDEQ.
The results reflect HMTC to be outside the benchmark value for the following:
• Copper and Zinc at SDO 93
• Copper at SDO #5
Additional attachments include the Laboratory Analytical Report, Chain -of -Custody, Rainfall
Record, and Qualitative Monitoring Report. Please contact Steve Street if you have any
questions regarding this submittal at 828-901-6695.
