1 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.
3The 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.
5 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).
Permit Date: 11/1/2018-05/31/2021 SWU-245, last revised 11/1/2018

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."

TIER I PERMIT COMPLIANCE INSPECTION
As required by General Stormwater Permit No. NCG030660, a compliance
evaluation was conducted on October 24, 2019 in response to the stormwater
analytical parameters exceedance. Present during the inspection were:
Paul W. Spangenberg Consultant, Director of Environmental Compliance
Jeremy Coble Plant 11 Manager
AREAS OF INSPECTIONS
1.) Areas where industrial activities are exposed to stormwater
a) Used equipment storage east of building 8. The
equipment was observed to be oil free. There was also
a closed top dumpster in this area. No evidence was
found of an impact to stormwater in this area.
b) Unloading/Loading Dock Areas: There was solid waste
dumpster at each building loading dock areas. The solid
waste was confined to the dumpsters and observed no
discharges. There were no signs of mismanagement of
regulated waste materials. The area was clean with no
staining.
c) Used wooden pallet storage east of building 8. The
pallets were observed to be oil free. There was also air
emission control equipment in this area. No evidence
was found of an impact to stormwater in this area.
Summary: With the exception of minor amounts of oil seepage from
the yard equipment, the following were not found during the
inspection:
a) leaks or spills from equipment, drums, barrels, or containers
b) off -site tracking of industrial materials
c) tracking or blowing of raw, final, or waste materials
d) evidence or, or the potential for, pollutants entering the drainage
system.

EVALUATION
2.) Analytical monitoring from Outfall 1 results from sampling
conducted on October 16, 2019 indicated the following
exceedances.
Date.
Parameters.
Copper
Parameters
TSS
3/21/19
0.0040
9.6
10/16/19
0.022
340
There is no apparent cause of the elevated copper levels. During the
inspection, the attempt to evaluate contributing factors of copper levels
were not found. No action related to the elevated copper level is
recommended at this time. The TSS exceedance were determined to
be erosion occurring in the drainage ditches between Plants 8 and 11.
However there was excavation activities accruing in close proximity
from the site. The drainage system managing the discharge is
common to the site.
3.) There are structural BMP's present at the facility. One retention
pond, and two collection basins, but no oil/water separators. Non-
structural BMP's include the minimization of outdoor storage, the
frequent disposal of accumulated wastes, and the elimination of
any oily wastes. These non-structural BMP's appear to be
adequate.
4.) The stormwater discharge outfall was inspected. There was
evidence of buildup of sediment and erosion preceding outfall was
observed. No other non-stormwater discharges were observed of
impacts at either of outfalls.
RECOMMENDATIONS
t) Schedule more frequent management of used equipment to minimize
the exposure to stormwater.
2) Implement erosion control preceding and proceeding outfall 1 discharge
point in the form of Rip -Rap to minimize erosion.
No evidence was found that the current SWPPP has any deficiencies. No
changes to the SWPPP are recommended at this time. All current initiatives
appear adequate to meet the goals of the SWPPP. Note that the SWPPP was
updated on 1 /1 /19, before the date that the inspection was conducted.

CERTIFICATION
This inspection did not reveal any violations of the permit. No areas of non-
compliance with the SWPPP were noted.

1 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.
3The 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.
4 See General Permit, Section B, Table 1 to identify the especially sensitive receiving water classifications where the more protective benchmark applies.
' 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."
