Certificate of Coverage # NCG030617
11707 Steele Creek Road,
Mecklenburg County, North Carolina
We received a request for relief from monthly monitoring regarding levels of zinc and copper in Stormwater
from this site exceeding the benchmark limits of the NCO030000 general permit. The facility was inspected on
September 28, 2016 by staff of this office accompanied by Ms.-L.anette Plyler.
Based on our inspection and the investigation of potential sources are not attributed by CoaLogix SCR -Tech,
and Division is granting regulatory relief from the Tier Two response for copper and zinc benchmark excecdances.
Upon receipt of this letter, the subject facility may continue the semi-annual analytical monitoring schedule as
specified in the general permit for the remainder of the current permit term. Your current permit is set to expire on
October 31, 2017. Please note that this monitoring relief applies only to zinc and copper. Any benchmark limit
exceedance of other parameters required by the permit will trigger the tiered response actions as described within
the general permit.
You must notify this office, in writing, within 5 business days if you become aware of any other significant
source of copper or zinc at your facility that has potential to affect Stormwater from the facility. The relief granted
in this letter is contingent upon the current practices at this facility. If any practices should deviate from current
activities and create significant Stormwater exposure risk, this office reserves the right to withdraw this decision and
reinstate the permit specified tiered response that may be warranted by any new circumstances.

Inspection Summary:
This inspection was conducted per request for technical assistance from Lanette Plyter. In November of 2015, analytical
monitoring resulted in copper and zinc levels exceeding the benchmark limits specified in the general permit for
NCG030000. These exceedances put Coalogix in Tier Two monitoring and monthly analytical monitoring began in
December of 2015. After investigation, Coalogix was unable to locate the source causing the stormwater to exceed the
benchmark limits.
During our inspection, we found that the site was well maintained and we were unable to locate the source of the copper
and zinc causing exceedances in the analytical monitoring. Because site conditions reflect compliance with all stipulations
of general permit NCG030000, this site may return to Tier One montioring 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.
a 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.
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: 11/1/2012-10/31/2018 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."

Subject: Relief from Monthly Monitoring
NPDES Stormwater Permit NCG030000
Certificate of Coverage # NCG030617
11707 Steele Creek Road,
Mecklenburg County, North Carolina
We received a request for relief from monthly monitoring regarding levels of zinc and copper in stormwater
from this site exceeding the benchmark limits of the NCG030000 general permit. The facility was inspected on
September 28, 2016 by staff of this office accompanied by Ms.•Lanette Plyler.
Based on our inspection and the investigation of potential sources are not attributed by CoaLogix SCR -Tech,
and Division is granting regulatory relief from the Tier Two response for copper and zinc benchmark exceedances.
Upon receipt of this letter, the subject facility may continue the semi-annual analytical monitoring schedule as
specified in the general permit for the remainder of the current permit term. Your current permit is set to expire on
October 31, 2017. Please note that this monitoring relief applies only to zinc and copper. Any benchmark limit
exceedance of other parameters required by the permit will trigger the tiered response actions as described within
the general permit.
You must notify this office, in writing, within 5 business days if you become aware of any other significant
source of copper or zinc at your facility that has potential to affect stormwater from the facility. The relief granted
in this letter is contingent upon the current practices at this facility. If any practices should deviate from current

Inspection Summary:
This inspection was conducted per request for technical assistance from Lanette Plyler. In November of 2015, analytical
monitoring resulted in copper and zinc levels exceeding the benchmark limits specified in the general permit for
NCG030000. These exceedances put Coalogix in Tier Two monitoring and monthly analytical monitoring began in
December of 2015, After investigation, Coalogix was unable to locate the source causing the stormwater to exceed the
benchmark limits.
During our inspection, we found that the site was well maintained and we were unable to locate the source of the copper
and zinc causing exceedances in the analytical monitoring, Because site conditions reflect compliance with all stipulations
of general permit NCG030000, this site may return to Tier One moniiorng requirements.

SCR -Tech, LLC; 11707 Steel Creek Road, Charlotte, NC 28273
Dear DWQ:
Please find attached the July -December 2017 Semi-annual Stormwater Discharge Monitoring Report
for the SCR -Tech, LLC facility covered by Certificate of Coverage NCG030617 and located at 11707
Steele Creek Road, Charlotte, NC 28273.
Note that the sampling for this report occurred on August 31, 2017. The report is just now being
submitted because the results were not received by the company until November 28, 2017. Thus,
report submission is being completed as required within 30 days of receipt of analytical results.' Per
the attached letter from Shealy Environmental, the original report of results was sent from Shealy
Environmental with incorrect labeling leading us to believe it was different water sampling performed
at another company facility. It was not until I contacted our Shealy Environmental this week about
getting our second semi-annual sampling completed for the year that I was made aware of the mix up
on the reporting.
Please contact me at 704-414-4621(offce) or 980-722-1811(cell) should you have questions regarding
this stormwater sampling report.

' 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).

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."

Subject: Relief from Monthly Monitoring
NPDES Stormwater Permit NCG030000
Certificate of Coverage # NCG030617
11707 Steele Creek Road,
Mecklenburg County, North Carolina
We received a request for relief from monthly monitoring regarding levels of zinc and copper in stormwater
from this site exceeding the benchmark limits of the NCG030000 general permit. The facility was inspected on
September 28, 2016 by staff of this office accompanied by Ms. Lanette Plyler.
Based on our inspection and the investigation of potential sources are not attributed by CoaLogix SCR -Tech,
and Division is granting regulatory relief from the Tier Two response for copper and zinc benchmark exceedances.
Upon receipt of this letter, the subject facility may continue the semi-annual analytical monitoring schedule as
specified in the general permit for the remainder of the current permit term. Your current permit is set to expire on
October 31, 2017. Please note that this monitoring relief applies only to zinc and copper. Any benchmark limit
exceedance of other parameters required by the permit will trigger the tiered response actions as described within
the general permit.
You must notify this office, in writing, within 5 business days if you become aware of any other significant
source of copper or zinc at your facility that has potential to affect stormwater from the facility. The relief granted
in this letter is contingent upon the current practices at this facility. If any practices should deviate from current
activities and create significant stormwater exposure risk, this office reserves the right to withdraw this decision and
reinstate the permit specified tiered response that may be warranted by any new circumstances.

Dear Ms- Plyler:
Shealy Environmental Services, Inc. ("Shealy") analyzed Stormwater samples for STEAG SCR-Tech's Steele Creek facility
on August 31, 2017. The results were reported under Shealy lot number S101059. The report incorrectly listed Kings
Mountain facility as the project name when submitted on September 15, 2017. As a result, the report was mistaken
for preliminary stormwater sampling being performed at the Kings Mountain facility at that time. The corrected report
was submitted to STEAG SCR -Tech on November 28, 2017.

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.
-'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."

Subject: Relief from Monthly Monitoring
NPDES Stormwater Permit NCG030000
Certificate of Coverage # NCG030617
11707 Steele Creek Road,
Mecklenburg County, North Carolina
We received a request for relief from monthly monitoring regarding levels of zinc and copper in stormwater
from this site exceeding the benchmark limits of the NCG030000 general permit. The facility was inspected on
September 28, 2016 by staff of this office accompanied by Ms..Lanette Plyler.
Based on our inspection and the investigation of potential sources are not attributed by CoaLogix SCR -Tech,
and Division is granting regulatory relief from the Tier Two response for copper and zinc benchmark exceedances.
Upon receipt of this letter, the subject facility may continue the semi-annual analytical monitoring schedule as
specified in the general permit for the remainder of the current permit terra. Your current permit is set to expire on
October 31, 2017. Please note that this monitoring relief applies only to zinc and copper. Any benchmark limit
exceedance of other parameters required by the permit will trigger the tiered response actions as described within
the general permit.
You must notify this office, in writing, within 5 business days if you become aware of any other significant
source of copper or zinc at your facility that has potential to affect stormwater from the facility. The relief granted
in this letter is contingent upon the current practices at this facility. if any practices should deviate from current
activities and create significant stormwater exposure risk, this office reserves the right to withdraw this decision and
reinstate the permit specified tiered response that may be warranted by any new circumstances.

Inspection Data: 0912812016 Inspection Type: Technical Assistance Reason for Visit: Other
Inspection Summary:
This inspection was conducted per request for technical assistance from Lanette Plyler. In November of 2015, analytical
monitoring resulted in copper and zinc levels exceeding the benchmark limits specified in the general permit for
NCG030000. These exceedances put Coalogix in Tier Two monitoring and monthly analytical monitoring began in
December of 2015. After investigation, Coalogix was unable to locate the source causing the stormwater to exceed the
benchmark limits.
During our inspection, we found that the site was well maintained and we were unable to locate the source of the copper
and zinc causing exceedances in the analytical monitoring. Because site conditions reflect compliance with all stipulations
of general permit NCG030000, this site may return to Tier One moniorng requirements.

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.
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).

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."

Subject: Relief from Monthly Monitoring
NPDES Stormwater Permit NCG030000
Certificate of Coverage # NCG030617
11707 Steele Creek Road,
Mecklenburg County, North Carolina
We received a request for relief from monthly monitoring regarding levels of zinc and copper in stormwater
from this site exceeding the benchmark limits of the NCG030000 general permit. The facility was inspected on
September 28, 2016 by staff of this office accompanied by Ms.-Lanette Plyler.
Based on our inspection and the investigation of potential sources are not attributed by CoaLogix SCR -Tech,
and Division is granting regulatory relief from the Tier Two response for copper and zinc benchmark exceedances.
Upon receipt of this letter, the subject facility may continue the semi-annual analytical monitoring schedule as
specified in the general permit for the remainder of the current permit term. Your current permit is set to expire on
October 31, 2017. Please note that this monitoring relief applies only to zinc and copper. Any benchmark limit
exceedance of other parameters required by the permit will trigger the tiered response actions as described within
the general permit.
You must notify this office, in writing, within 5 business days if you become aware of any other significant
source of copper or zinc at your facility that has potential to affect stormwater from the facility. The relief granted
in this letter is contingent upon the current practices at this facility. If any practices should deviate from current
activities and create significant stormwater exposure risk, this office reserves the right to withdraw this decision and
reinstate the permit specified tiered response that may be warranted by any new circumstances.

Inspection Summary:
This inspection was conducted per request for technical assistance from Lanette Plyler. In November of 2015, analytical
monitoring resulted in copper and zinc levels exceeding the benchmark limits specified in the general permit for
NCG030000. These exceedances put Coalogix in Tier Two monitoring and monthly analytical monitoring began in
December of 2015. After investigation, Coalogix was unable to locate the source causing the stonnwater to exceed the
benchmark limits.
During our inspection, we found that the site was well maintained and we were unable to locate the source of the copper
and zinc causing exceedances in the analytical monitoring. Because site conditions reflect compliance with all stipulations
of general permit NCG030000, this site may return to Tier One montioring requirements.
