' 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 maybe 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
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 "

FLAGIQUALIFIER SUMMARY
QC result is outside ofestablished limns
t Wide recovery limits established for difficult compound
t Wide RPD limns established for difficult compound
k Dam exceeded client recommended or regulatory level
ND Not Detected
RL Reporting Limit is at the level of quanntation (LOQ)
DL Detection Limit is the lower ]unit of detechon determined by the MDL study
MCL Maxumutn Contaminant Level
Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
Lalculation which have not beam rounded
No results have been blank subtracted unless specified in the case narrative section
H-05 Holding time was exceeded pH analysis should be performed immediately at time of samphrig Nominal 15
minute holding time was exceeded
I Detected but below the Reporting Limit (lowest calibration standard) therefore result is an estimated
concentration (CLP J Flag)
R-04 Duplicate relative percent difference (RPD) is a less useful indicator of sample precision for sample results that
we <5 times the reporting lumt (RL)

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
;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
4 See General Permit, Table 3 identifying 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 11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012
Page 1 of 3

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 1 further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Starmwater Pollution Prevention Plan "

a See General Permit, Table 3 identifying 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 46912, 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 "

ASHEBORO, NORTH CAROLINA
TIER I PERMIT COMPLIANCE INSPECTION
As required by General Stormwater Permit No NCG030675, a compliance
evaluation was conducted on August 23, 2017 in response to the stormwater
analytical parameters exceedance Present during the inspection were
Paul w Spangenberg Consultant, Director of Environmental Compliance
Audie Tucker Plant Manager
AREAS OF INSPECTIONS
1 ) Areas where industrial activities are exposed to stormwater
a) Used equipment storage north of main building The
equipment was observed to be oil free There was also
a closed top dumpster, and air emission control
equipment in this area No evidence was found of an
impact to stormwater in this area
b) Used equipment storage west of main building The
equipment was observed to be oil free There was also
a chemical storage shed and a waste storage shed in
this area No evidence was found of an impact to
stormwater in this area
c) Used equipment storage east of main building The
equipment was observed to be oil free There was also
an aboveground diesel fuel and propane tanks in this
area No evidence was found of an impact to
stormwater in this area
d) Used equipment storagesouth of main building The
equipment was 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 results from sampling conducted on
August 8, 2017 indicated the following exceedances
Parameters
Benchmark
1
Outfall1
Outfall2
Zinc
0 067 m IL
0 65 m IL
0 55 m IL
There is no apparent cause of the elevated zinc level During the inspection,
the attempt to evaluate the background of zinc levels in determining any
contributing factor were not found No action related to the elevated zinc
level is recommended at this time
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) Each of the three stormwater discharge outfalls were inspected
There was evidence of buildup sediment and erosion preceding
outfalls #2 was observed No other non-stormwater discharges were
observed of impacts at either of outfalls
RECOMMENDATIONS
1} Schedule more frequent management of used equipment to minimize
the exposure to stormwater
2) Implement erosion control on the travel lanes in the form of gravel to
minimize erosion
3) Implement erosion control preceding and proceeding outfall 2 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 3/11/2017, 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

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at thee e outfall
2 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, Table 3 identifying 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 eo to arned 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,ta dl or cathode ray

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 70 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 "
