Stormwater Discharge Outfall (SDO)
Monitoring Report and Benchmark overage explanation
Kennametal Inc.
Dear Sir or Madam:
We have completed the Stormwater Discharge Outfall (SDO) Monitoring Report, as
require by General Stormwater Discharge Permit, NCG030000, Tier II Level
requirements.
No representative sampling was performed in March 2019 due to lack of
measurable stormwater event. Per Tier II, Item 2, Then Permittee shall: Submit a
monthly monitoring report indicating "No Flow" if no discharge occurs during
sampling period.
As required under Section B: Analytical Monitoring Requirements
Tier One level (Actions Completed)
1. Conducted a stormwater management inspection of the facility,
a. Property inspection conducted by; Donald Baird, Richard Tudor and David
Kannianen
2. Identified and evaluated possible causes of benchmark value exceedance

a. We have no industrial activities outside of the facility that would contribute
to this exceedance.
i. All storage containers are covered and protected from stormwater,
ii. No machinery or equipment is stored or serviced, where it would be
exposed to stormwater.
iii. Building and property are well maintained and litter/debris, free.
iv. Parking lot does not exhibit above normal signs of vehical leakage.
3. There are no identified, feasible source controls, operational controls or physical
improvements that we can identify to bring concentrations within the benchmark
range.
5. Recorded each instance of Tier One response in our SPPP plan, documenting;
a. Date
b. Value of benchmark exceedance
c. Inspection date
d. Personnel conducting the inspection
e. Selected actions
f. Date the selected actions were implemented
Tier Two Level
2. Instituting monthly monitoring for all reporting parameters
a. Analytical and Qualitative sampling until three consecutive sample results
are below the benchmark values or within the benchmark range.
3. If no discharge occurs during the sampling period, we still have to submit a
monthly monitoring report indicating, "No Flow" to comply with the reporting
requirements.
4. We will exercise the option of contacting the DEMLR Regional Engineer as listed
in Tier Three. The Regional Engineer may direct the response actions on the
part of the permittee as provided in Tier Three, including reduced or additional
sampling parameters or frequency.
5. Maintain a record of the Tier Two response in our SPPP
6. Continue Tier Two response obligations throughout the permit renewal process.

We will resume sampling in April 2019 per our Tier II requirements.

Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
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 Pert -nit, Table 3 identifying 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).
Permit Date: 11/l/2012-10/31/2017 SWU-245, last revised 10/25/2012

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 storrnwater 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."

Stormwater Discharge Outfall (SDO)
Monitoring Report and Benchmark overage explanation
Kennametal Inc.
Dear Sir or Madam:
BAN 02 zol9
0WR SC-Cilpnj
We have completed the Stormwater Discharge Outfall (SDO) Monitoring Report, as
require by General Stormwater Discharge Permit, NCG030000. The original report and
one completed copy of the Stormwater samples taken on October 26, 2018 are
enclosed.
The representative sampling was performed as required during a measurable storm
event and sampling was conducted at the outfall listed on our stormwater permit.
In addition, we collected samples from an adjacent property which we believe impacts
our site stormwater discharge characteristics. This is the second sampling we have
taken from this point and in both cases, there were elevated levels (above benchmark
targets) for copper and zinc.
As required under Section B: Analytical Monitoring Requirements

Tier One level (Actions Completed)
1. Conducted a stormwater management inspection of the facility,
a. Property inspection conducted by; Donald Baird, Richard Tudor and David
Kannianen
2. Identified and evaluated possible causes of benchmark value exceedance
a. We have no industrial activities outside of the facility that would contribute
to this exceedance.
i. All storage containers are covered and protected from stormwater,
ii. No machinery or equipment is stored or serviced, where it would be
exposed to stormwater.
iii. Building and property are well maintained and litter/debris, free.
iv. Parking lot does not exhibit above normal signs of vehical leakage.
3. There are no identified, feasible source controls, operational controls or physical
improvements that we can identify to bring concentrations within the benchmark
range.
4. NA
5. Recorded each instance of Tier One response in our SPPP plan, documenting;
a. Date
b. Value of benchmark exceedance
c. Inspection date
d. Personnel conducting the inspection
e. Selected actions
f. Date the selected actions were implemented
Tier Two Level
1. Instituting monthly monitoring for all reporting parameters
a. Analytical and Qualitative sampling until three consecutive sample results
are below the benchmark values or within the benchmark range.
2. If no discharge occurs during the sampling period, we still have to submit a
monthly monitoring report indicating, "No Flow" to comply with the reporting
requirements.
3. We will exercise the option of contacting the DEMLR Regional Engineer as listed
in Tier Three. The Regional Engineer may direct the response actions on the
part of the permittee as provided in Tier Three, including reduced or additional
sampling parameters or frequency.

4. Maintain a record of the Tier Two response in our SPPP
5. Continue Tier Two response obligations throughout the permit renewal process.
In conclusion we will continue to monitor our outside industrial activities for possible
contributing factors and if identified, place controls in place to address them. We will
also contact the "DEMLR Regional Engineer, Bethany Georgoulias ([phone] or
Rick Riddle ([phone] to seek their counsel and advice to address these sampling
results.

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
'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).

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."

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,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).

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."

Dear Sirs,
This report contains additional Stormwater sampling information as stated in Stormwater
Discharge Monitoring Report provided on June 191h.2018. Second sample designated as
"Stormwater 2 Grab" or "Stormwater Across Street" was done as a reaction to investigation
done on 6/13/18 due to elevated Copper and Zinc levels shown on Meritech report dated
6/11/18.
As a result we feel another Stormwater source is effecting our outfall reporting data.
Thank you,
Richard Tudor

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
'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, Table 3 identifying 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).
Permit Date: 11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012

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."

Storm water sampling pulled on 5/16/18 per semiannual requirements by Donald Baird
Testing results indicated 2 parameters to be over benchmark target,
Copper — Benchmark Target value = 0.007 mg/L, Test results 0.019 mg/L, Retested
results 0.0195 mg/L
Zinc - Benchmark Target value = 0.067 mg/L, Test results 0.099 mg/L, Retested results
0.140 mg/L
Conducted Storm Water Management Inspection of Facility and Grounds on 6/13/18 at
9:OOam. Danny Allen, Donald Baird, Richard Tudor conducted inspection.
Possible causes of exceedance of benchmark values:
• Storm water from closed factory (Old Flambeau factory)and Weldon Steel feeds directly
into drainage ditch across from our property which feeds directly into our storm water
outfall.
Actions to be taken.
• Will grab sample incoming storm water from upstream source at roadway as well as our
Outfall 1. This will provide us comparison data.

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.
'Total Toxic Organics samp)ing 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."

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.
s Total Toxic Organics samp)ing is applicable only for those facilitieg 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."

1 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."

1 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."

1 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."

I 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."
