DNJR SECTION
RE: STORMWATER DISCHARGE OUTFALL ANALYSIS AND LAB RESULTS
To Whom It May Concern —
During the month of March 2019, a grab sample was collected for the GKN
Driveline Roxboro Facility (General Permit NCG030000, Certificate of Coverage
NCG030429).during a measureable storm event. The rainfall and sample
conditions were ideal for sufficient grab samples from our three headwall
locations. All three outfall locations exceed zinc levels by small margins. Two
locations exceeded the reporting limit for Total Suspended Solids and one
location exceeded copper levels by a minimal amount.
We will continue to monitor our outfalls as allowable. No other abnormalities
were observed during the grab sampling process.
If you have any questions, please contact the undersigned at your earliest
convenience. Thank you for your continued support of GKN Driveline's
environmental, health, and safety programs.
Respectfully submitted,
James M. Wolak

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.
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 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 Tf0 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
Pet7nit. For those facilities electing to employ the T O 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
(Tf0), 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 flan."

RE: STORMWATER DISCHARGE OUTFALL ANALYSIS AND LAB RESULTS
To Whom It May Concern —
During the month of February 2019, a grab sample was collected for the GKN
Driveline Roxboro Facility (General Permit NCG030000, Certificate of Coverage
NCG030429) during a measureable storm event. The rainfall and sample
conditions were marginal for sufficient grab samples from our three headwall
locations. Although it was a significant rain event, the water flow was very slow.
All three outfall locations exceed copper and zinc by minimal margins. All three
outfalls exceeded the reporting limit for Total Suspended Solids, which can be
attributed to the very slow water flow.
We will continue to monitor our outfalls as allowable. No other abnormalities
were observed during the grab sampling process.
If you have any questions, please contact the undersigned at your earliest
convenience. Thank you for your continued support of GKN Driveline's
environmental, health, and safety programs.
Respectfully submitted,
James M. Wolak

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."

RE: STORMWATER DISCHARGE OUTFALL ANALYSIS AND LAB RESULTS
To Whom It May Concern —
During the month of June 2018, a grab sample was collected for the GKN
Dr oro Facility (General Permit NCG030000, Certificate of Coverage
e'NCGO30429)-Vuring a measureable storm event. The rainfall and sample
ere ideal for sufficient grab samples from our three headwall
locations. All three outfall locations exceed copper and zinc by minimal margins.
Outfall #7 and #9 exceeded the reporting limit for Total Suspended Solids.
We will continue to monitor our outfalls as allowable. No other abnormalities
were observed during the grab sampling process.
If you have any questions, please contact the undersigned at your earliest
convenience. Thank you for your continued support of GKN Driveline's
environmental, health, and safety programs.
Respectfully submitted,

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a 'representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event' is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
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.

RE: STORMWATER DISCHARGE DUTFALL ANALYSIS AND LAB RESULTS
To Whom It May Concern —
During the month of February 2018, a grab sample was collected for the GKN
Driveline Roxboro Facility (General Permit NCG030000, Certificate of Coverage
NCG030429) during a measureable storm event. We could not obtain a sufficient
grab sample from one of our sample locations (headwall #5). Some of the grab
samples demonstrate exceedances in Copper, Lead and Zinc. There was also
an unusual amount of TSS in one of the samples.
We will continue to monitor as allowable and are looking at maintenance options
to our outfalls.
If you have any questions, please contact my office at your earliest convenience.
Thank you for your continued support of GKN Driveline's environmental, health,
and safety programs. RECEIVED

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 5tormwater 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), 1 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."

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event"or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event" However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
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

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "meosureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
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.

RE: STORMWATER DISCHARGE OUTFALL ANALYSIS AND LAB RESULTS
To Whom It May Concern —
During the month of December 2017, a grab sample was collected for the GKN
Driveline Roxboro Facility (General Permit NCG030000, Certificate of Coverage
NCG030429) during a measureable storm event. Due to the extended dry climate
conditions over the past several months, we could not obtain a sufficient grab
sample from one of our sample locations (headwall #5). Some of the grab
samples demonstrate exceedances in Copper, Lead and Zinc and Copper.
There was also an unusual amount of TSS in one of the samples.
We believe that these exceedances are a result of the drought conditions over
the last 6 months. We will continue to monitor as allowable.
If you have any questions, please contact my office at your earliest convenience.
Thank you for your continued support of GKN Driveline's environmental, health,
and safety programs.

Visual Monitoring Results —Summary
GKN Driveline North America, Inc.
Roxboro Facility
6400 Durham Road
Timberlake, North Carolina 27583, USA
Visual inspections of the outfall areas (#5, 97, and #9) are completed with each
stormwater collection or every b months, at a minimum. Below is a summary of each
outfall, the visual inspection criteria, and consolidated findings from the inspection.
Criteria for Visual Monitoring
Color — Color of the discharge and the level of color saturation.
Odor — Identification of any distinct odor that the discharge may have.
Clarity — The ability to see through the discharge.
Floating Solids — The amount of debris or other solid matter in the discharge.
Suspended Solids — The amount of solid material suspended in the discharge.
Foam -- Presence.
Oil Sheen Presence.
Erosion or Deposition — Presence.
Visual survey of the immediate area and drainage areas for any obvious indicators of
pollution.
Headwall #5
The headwall structure is a pipe which discharges to UT to North Flat River. The area
where this headwall is located is near a shipping area with commercial semi -truck traffic.
Most drainage from the outfall comes from a grassy area maintained by GKN to the
northeast side of the property.
The discharge on this headwall is generally clear, with no noticeable odor. Clarity is
good with very minimal floating or suspended solids. There has been no indication of
foam, oil sheen, or erosion/deposition in the discharge samples.
Headwall #7
The headwall structure is a pipe which discharges to UT to North Flat River. The
headwall receives drainage from the facility roof and outside plastic dunnage which is
stored on concrete.
The discharge on this headwall is generally clear, with no noticeable odor. Clarity is
good with very minimal floating and some suspended solids. There has been no
indication of foam, oil sheen, or erosion/deposition in the discharge samples.
Headwall #9
The headwall structure is a pipe which discharges to UT to North flat River. The
headwall receives drainage from the facility outside storage area which stores plastic
dunnage and has high traffic from semi -trucks on concrete.

The discharge on this headwall is generally clear, with no noticeable odor. Clarity is
good with very minimal floating and suspended solids. There has been no indication of
foam, oil sheen, or erosion/deposition in the discharge samples.
All headwalls have demonstrated exceedances in Zinc and Copper over the past 2 years,
as evidenced by analytical monitoring. There is minimal evidence of suspended or
floating solids. However, the amount of TSS does increase when samples are taken after
periods of drought.
Best Management Practices and Significant Changes to the Factility
There have been several improvements to the GKN outside staging areas to improve
handling and storage and minimize stormwater pollution.
Spill Team — GKN had trained and implemented a Spill Response Team for all operations
shifts. The Team is trained to identify, contain, clean up, storage, and properly dispose of
any spill inside and outside of the facility. The team is trained annually and a review is
completed for each spill that occurs on site_
Reduction of Dunnage — Over the last two years, GKN has made an effort to minimize
the amount of dunnage that is required to be stored on -site —a reduction of approximately
30 percent. Unused or outdated materials were sent to plastic and metal recycling. Slow -
running dunnage was sent to an off -site warehouse location in Sanford, NC. Currently,
the site stores only materials for high -running, fast ship parts.
Roof Design — After an audit of the facility, the flow of water from the roof was
reviewed. Drainage downspouts were changed and engineered to minimize
contamination of water the is being discharged from the roof locations.
Waste Stream Handling — In Q3 2017, GKN Roxboro will employ a company called Zero
Waste Recycling to manage all of its waste streams and take the facility to zero waste to
landfill by 2018. Part of this project includes reduction of waste storage on -site,
especially in outside areas of the facility.

Reduction of Dunnage — Over the last two years, GKN has made an effort to minimize
the amount of dunnage that is required to be stored on -site —a reduction of approximately
30 percent. Unused or outdated materials were sent to plastic and metal recycling. Slow -
running dunnage was sent to an off -site warehouse location in Sanford, NC. Currently,
the site stores only materials for high -running, fast ship parts.
Roof Design — After an audit of the facility, the flow of water from the roof was
reviewed. Drainage downspouts were changed and engineered to minimize
contamination of water the is being discharged from the roof locations.
Waste Stream Handling — In Q3 2017, GKN Roxboro will employ a company called Zero
Waste Recycling to manage all of its waste streams and take the facility to zero waste to
landfill by 2018. Part of this project includes reduction of waste storage on -site,
especially in outside areas of the facility.

NCG030429) during a measureable storm event. Some of the grab samples
demonstrate exceedances in Zinc and Copper.
A grab sample could not be collected from Headwall #5 location due to lack of
discharge. Maintenance has been schedule on this location to ensure there is no
blockage to the drainage line.
If you have any questions, please contact my office at your earliest convenience.
Thank you for your continued support of GKN Driveline's environmental, health,
and safety programs.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event'or "measureablestorm event' (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event' or during a "measureable storm event" However,
some permits do not have this requirement Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
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.

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same 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 retarded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
a 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
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. 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 Monthly sampling (instead of semi-annual) must begin with the second consecutive be k exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall, you must still submit this d e ito ' g report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattend aW,nufkture
aiver of the rain gauge requirement.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications w te benchmark applies.
Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operatisemiconductors, 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."

RE: STORMWATER DISCHARGE OUTFALL ANALYSIS AND LAB RESULTS
To Whom It May Concern —
During the month of February-2016, a grab sample was collected for the GKN
Driveline Roxboro Facility (General Permit NCG030000, Certificate of Coverage
tNCG030429)-during a measureable storm event. Some of the grab samples
demonstrate exceedances in Zinc and Copper.
Despite that Zinc and Copper still demonstrate these exceedances, the total
reported amount of the sample has notably decreased from the last testing
period. We will continue to monitor these outfalls, as required.
If you have any questions, please contact my office at your earliest convenience.
Thank you for your continued support of GKN Driveline's environmental, health,
and safety programs.
Respectfully submitted,

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event" However,
some permits do not have this requirement Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
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.

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

RE: STORMWATER DISCHARGE OUTFALL ANALYSIS AND LAB RESULTS
To Whom It May Concern --
During the month of December 2015, a grab sample was collected for the GKN
Driveline Roxboro Facility (General Permit NCG030000, Certificate of Coverage
NCG030429) during a measureable storm event. Some of the grab samples
demonstrate exceedances in Zinc and Copper.
In order to improve our water discharge, we have completed continuous
improvement plans for our tray storage area. Unfortunately, we there are no
significant improvements to the Zinc and Copper discharge. We will continue to
monitor as required. Policy Deployment and Continuous Improvement Planning
is scheduled for January 2016. Additional plans for improvement will be added to
the 2016 schedule in order to reduce the amount of Zinc and Copper in the
stormwater runoff.
If you have any questions, please contact my office at your earliest convenience.
Thank you for your continued support of GKN Driveline's environmental, health,
and safety programs.

some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
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

RE: STORMWATER DISCHARGE OUTFALL ANALYSIS AND LAB RESULTS
To Whom It May Concern —
During the month of November 2015, a grab sample was collected for the GKN
Driveline Roxboro Facility (General Permit NCG030000, Certificate of Coverage
NCG030429) during a measureable storm event. Some of the grab samples
demonstrate exceedances in Zinc and Copper.
In order to improve our water discharge, we have completed continuous
improvement plans for our tray storage area. Unfortunately, we there are no
significant improvements to the Zinc and Copper discharge. We will continue to
monitor as required. Policy Deployment and Continuous Improvement Planning
is scheduled for January 2016. Additional plans for improvement will be added to
the 2016 schedule in order to reduce the amount of Zinc and Copper in the
stormwater runoff.
If you have any questions, please contact my office at your earliest convenience.
Thank you for your continued support of GKN Driveline's environmental, health,

RE: STORMWATER DISCHARGE OUTFALL ANALYSIS AND LAB RESULTS
To Whom It May Concern —
During the month of October 2015, a grab sample was collected for the GKN
Driveline Roxboro Facility (General Permit NCG030000, Certificate of Coverage
NCG030429) during a measureable storm event. Some of the grab samples
demonstrate exceedances in Zinc and Copper.
In order to improve our water discharge, we have completed continuous
improvement plans for our tray storage area. Unfortunately, we there are no
significant improvements to the Zinc and Copper discharge. We will continue to
monitor as required and will make an effort to add additional continuous
improvement plans —including removal of unused or slow -moving dunnage —
before the close of 2015.
If you have any questions, please contact my office at your earliest convenience.
Thank you for your continued support of GKN Driveline's environmental, health,
and safety programs.
Respectfully submi ed,
Amy E Hughes, MS GSP

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event" However,
some permits do not have this requirement Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
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.

RE: STORMWATER DISCHARGE OUTFALL ANALYSIS AND LAB RESULTS
To Whom It May Concern —
During the month of April 2015, a grab sample was collected for the GKN
Driveline Roxboro Facility (General Permit NCG030000, Certificate of Coverage

during a measureable storm event. Some of the grab samples
exceedances in Zinc and Copper.
In order to improve our water discharge, we have relocated some of our metal
product from under a tented area outside the facility to a new storage location
inside the facility. We will continue to monitor as required.
If you have any questions, please contact my office at your earliest convenience.
Thank you for your continued support of GKN Driveline's environmental, health,

Please find enclosed the monthly (January) SDO grab sample analysis
monitoring report for the GKN Driveline Roxboro Facility (General Permit
NCG030000, Certificate of Coverage NCG030429). This sample demonstrates
exceedances.
In response to the exceedances, GKN has rerouted roof stormwater discharge
points to avoid possible contamination. GKN also hired a third party contractor to
clean and flush the drainage systems.
If you have any questions regarding these sample results, please contact my

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 thepermittee is able to document that a shorter -
interval is representative for local storm events during the sampling period, and the permittee
obtains annroval from the local DWO ReLyional Office.

RE: STORMWATER DISCHARGE OUTFALL ANALYSIS AND LAB RESULTS
To Whom It May Concern —
Please find enclosed the monthly (November) SDO grab sample analysis
monitoring report for the GKN Driveline Roxboro Facility (General Permit
NCG030000, Certificate of Coverage NCG030429). This sample demonstrates
exceedances.
In response to the exceedances, GKN has rerouted roof stormwater discharge
points to avoid possible contamination. GKN also hired a third party contractor to
clean and flush the drainage systems.
If you have any questions regarding these sample results, please contact my
office at your earliest -convenience. Thank you for your continued support of
GKN Driveline's environmental, health, and safety programs.

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

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
r maybe 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."

Stormwater Discharge Outfall Analysis and Monitoring Reports
To Whom It May Concern:
Enclosed please find the monthly SDO grab sample analysis monitoring report
for the GKN Driveline Roxboro Facility. Monthly sampling was initiated after
receiving the semi-annual results which indicated repeated exceedances for zinc
and copper.
The samples continue to indicate high levels of copper and zinc. We are in the
process of implementing a suitable response which will include filtration at the
stormwater drains. As soon as the controls are implemented, we will determine if
they are effective.
I also included test results for straight rainwater which demonstrate measurable
amounts of copper and zinc, and which adversely contributes to exceedances.
If you have any questions regarding this letter or the enclosed please do not
hesitate to contact me at [phone].
Thank you for your continued support of the environmental, health and safety
program at GKN Driveline — Roxboro Facility.
Sincerely,
Ernie Nagy
