with General Permit Part II Section B, enclosed please find duplicate signed copies of Railroad Friction Products (RFPC) Stori
tfall Monitoring Report. This report summarizes analytical monitoring of the site's single outfall and covers the period of Jar
June 30, 2019. Below issue RFPC wants to make DWQ aware of.
)ncentration for zinc remains above listed benchmark value of 0.126 mg/L. During some previous sampling periods zinc sam
were higher that the listed zinc benchmark range of 0.126 mg/L. The sampling value for first half 2018 was 0.108 mg/L. Th
ing value for second half 2018 was 0.249 mg/L. This monitoring period, the zinc sampling value was 0.144 mg/L. This reoccL
ver benchmark value has been communicated to DWQ. In a letter issued from NCDEQ to RFPC dated May 25, 2018, RFPC wi
!d regulatory relief in the form of a collapsed Tier2-Tier 3 response, and RFPC may resume the permitted specified semi-anni
ical monitoring at our facility. RFPC continues to implement actions to mitigate exposure of storm water to materials. For e
3uilt a building to house the open top reject lined hoppers that holds loose reject material. This building blocks windborne d
ject hopper being blown to adjacent facility drainage creek. RFPC has also instituted better housekeeping requirements in o
nt production material from flowing into the facility drainage creek. In addition, RFPC has installed a StormCeptor unit wher
drains in back of factory that captures any particles in the storm water to prevent them reaching the drainage creek. Based
story relief granted in the May 25, 2018 letter, RFPC stopped monthly zinc monitoring.

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
obtains approval from the local DWQ Regional Office.

Dear Mr. Thompson:
On May 23, 2018, a site inspection was conducted for the Railroad Friction Products Corporation facility
located at 13601 Airport Road, Maxton, Scotland County, North Carolina. A copy of the Compliance
Inspection Report is enclosed for your review. Your time and assistance provided during the inspection is
greatly appreciated. The site visit and file review revealed that the subject facility is covered by NPDES
Stormwater General Permit NCG030000 under Certificate of Coverage NCG030108. Permit coverage
authorizes the discharge of stormwater from the facility to receiving waters designated as an unnamed
tributary to Shoe Heel Creek, a Class C;Sw waterbody in the Lumber River Basin.
As a result of the inspection, the facility was found to be in compliance with the conditions of the NCG030000
permit. Please refer to the enclosed Compliance Inspection Report for additional comments and
observations made during the inspection.
Please be advised that violations of the NPDES Stormwater General Permit are subject to a civil
penalty assessment of up to $25,000 per day for each violation. If you or your staff have any questions,

concentration for zinc remains above listed benchmark value, and RFPC is in Tier III status. During some previous sampling
pled values were higher that the listed zinc benchmark range of 0.067 mg/L. The sampling value for first half 2018 was 0.10
reoccurring zinc over benchmark value has been communicated to DWQ. RFPC has instituted better housekeeping require
?r to prevent production material from flowing into the facility drainage creek. In addition, in September 2014 RFPC installe
mCeptor unit where storm water drains in back of factory that captures any particles in the storm water to prevent them re
nage creek. RFPC continues monthly zinc monitoring to confirm this analysis.

will prevent windblown erosion of product into the drainage creek. RFPC has also begun conducting monthly monitoring of
(2) separate storm water downspouts from factory roof. Results so far indicate significantly higher than listed benchmark v;
in the storm water flowing from the factory roof. As of this writing, a representative from Fayetteville Regional Office is plz
to RFPC to review our facility and discuss options relating to our higher than benchmark zinc values. RFPC looks forward to
discussing possible improvements to our facility.

All sample aliquots were received at the correct temperature, in the proper containers, with the
RP
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
RChave
been corrected for the dilution factor used in the analysis. All radiochemical sample results for
solids are reported on a dry weight basis with the exception of tritium, carbon-14 and radon, unless wet
weight was requested by the client. All Method and Batch Quality Control are within established
FSSI
criteria except where addressed in this case narrative, a non-conformance form or properly qualified
within the sample results. By my digital signature below, I affirm to the best of my knowledge, all
problems/anomalies observed by the laboratory as having the potential to affect the quality of the data
have been identified by the laboratory, and no information or data have been knowingly withheld that
would affect the quality of the data.

(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Quality Control This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc) analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr) by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.

All permits require qualitative monitoring to be performed during a "measurable storm event."
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 DEMLR
Regional Office.

Subject: NPDES General Permit Renewal and Electronic Reporting Requirements
Railroad Friction Products Cor
NPDES Permit Certificate of Coverage (COC) Number: NCG030108
Dear NPDES Permittee:
The General Permit this facility is covered under expires on October 31, 2017. Our records indicate that
your annual fees are up to date; therefore, your coverage will be automatically renewed unless you
submit a rescission request for this permit. If you no longer need this permit, a rescission form can be
found on our website (http://goo.gl/BcgDP4).
The Stormwater Program plans to reissue this General Permit for one year with no changes. This
action has been posted for public comment on our website above (see the table of General Permits) and
published in area newspapers statewide. The public comment period for the reissuance action concludes
on November 1, 2017, and the new General Permit is scheduled to become effective on November 16,
2017. Upon issuance of the final General Permit, your coverage will be renewed for the one year
period. Instead of being mailed new Certificates of Coverage (COCs), each permittee should print off
the new General Permit Cover Page from our Stormwater Program website (with revised effective and
expiration dates) after issuance in mid -November.
Although the renewal process is automatic this year, two items require your action:
(1) You must review your permit contact information and notify us of any changes no later
than November 15, 2017.
(2) You must submit outfall information on-line for this site in preparation for electronic data
monitoring report (eDMR) requirements no later than November 30, 2017.
Permit Contact Information
Please review the permit contact information we have in our database. You can do this by clicking on
the "review the permit contacts for your facility" link on the website above and entering your permit
COC number. Ensure that Owner Affiliation and Permit Contact are accurate, and that e-mail addresses
are provided. (Note that if you already did this recently, we may not have entered the changes yet.)

concentration for zinc is above the listed benchmark value. During some previous sampling periods zinc sampled
higher that the listed zinc benchmark range of 0.067 mg/L. The sampling value for first half 2017 was 0.169 mg/L
iously communicated to DWQ, RPFC has instituted better housekeeping requirements in order to prevent producti
trial from flowing into the facility drainage creek. In addition, in September 2014 we installed a StormCeptor unit w
n water drains in back of factory that captures any particles in the storm water to prevent them reaching the draina
measured zinc levels have been trending downward, so it appears that the corrective measures implemented by F
essfully lowering zinc values. RFPC will continue monthly zinc monitoring to confirm this analysis. Previous resul

irther implement plans to eliminate any possibility of material reaching creek, we plan to install a shed over reject t
system. This will prevent windblown erosion of product into the drainage creek. Lastly, we are collecting zinc s�
ific points upstream of our factory. If the zinc values at these specific upstream points are higher than the benchr
)s, we will ask DWQ for higher zinc benchmark values.

concentration for copper is above the listed benchmark value of 0.007 mg/L. The sampling value for first half 201'
48 mg/L. Per our permit, this exceedance triggers Tier 1 requirements. RFPC conducted immediately conduct(
ection of the facility and found no obvious causes for copper exceedance. However, installing a shed over the reji

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
f permitted site outfali. The previous measurable storm event must have been at least 72 hours
i 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. I

:E: Storm water Discharge Outfall Monitoring Report
Railroad Friction Products Corporation, Maxton, North Carolina, Certificate of Coverage Number NCG030
Madam
ce with General Permit Part II Section B, enclosed please find duplicate signed copies of Railroad Friction Product
- Discharge Outfall Monitoring Report. This report summarizes analytical monitoring of the site's single outfall and
f July 1, 2016 through December 31, 2016. Below is one issue RPFC would like to discuss with DWQ.
,oncentrations for all discharge characteristics are below the listed benchmark values with the exception of zinc. C
previous sampling periods zinc sampled values were higher that the listed zinc benchmark range of 0.067 mg/L.
)ling value for second t half 2016 was 0.181 mg/L. As previously communicated to DWQ, RPFC has instituted b
ekeeping requirements in order to prevent production material from flowing into the facility drainage creek. In addi
amber 2014 we installed a StormCeptor unit wherestorm water drains in back of factory that captures any particle:
i water to prevent them reaching the drainage creek. The measured zinc levels have been trending downward, sc
ars that the corrective measures implemented by RFPC are successfully lowering zinc values. RFPC will continue
ronitoring to confirm this analysis. Previous results are shown below.
mber 2013: 1.200 mg/L
2014: 0.39 mg/L
amber 2014: 0.130 mg/L
per 2014: 0.086 mg/L
mber 2014: 0.350 mg/L
ary 2015: 0.050 mg/L
mber 2015: 0.129 mg/L
h 2016: 0.144 mg/L
mber 2016: 0.181 mg/L
rther implement plans to eliminate any possibility of material reaching creek, we also plan to design and implemen
m to ensure all reject break shoe material is put in closed bags prior to placing it in the reject materials hopper loc<
ack of this factory. This will prevent windblown erosion of product into the drainage creek. Lastly, we are currentl
Aing zinc samples of the surrounding area and will considering asking DWQ for higher zinc benchmark values if vz
iue to be higher than listed benchmark value.

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
obtains approval from the local DWQ Regional Office.

concentrations for all discharge characteristics are below the listed benchmark values. During some previous sarr
)ds zinc sampled values were higher that the listed zinc benchmark range of 0.067 mg/L. However, the first half 2(
pling period value was 0.050 mg/L, which is under the benchmark value. The sampling value for second half 201
9 mg/L, over the benchmark value. As previously communicated to DWQ, RPFC has instituted better housekeep
irements in order to prevent production material from flowing into the facility drainage creek. In addition, in Septer
istalled' a StormCeptor unit where storm water drains in back of factory that captures any particles in the storm wa
ent them reaching the drainage creek. The measured zinc levels have been trending downward, so it appears the
active measures implemented by RFPC are successfully lowering zinc values. RFPC will continue monthly zinc m
infirm this analysis. Previous results are shown below.

irther implement plans to eliminate any possibility of material reaching creek, we also plan to conduct a week long
it in early 2016 in which we will design and implement a system to ensure all reject break shoe material is put in cl(
to placing it in the reject materials hopper located in the back of this factory. This will prevent windblown erosion
uct into the drainage creek. Lastly, we are collecting zinc samples of the surrounding area and will considering as
igher zinc benchmark values if values continue to be higher than listed benchmark value.

DWR SECTION
CE: Storm water Discharge Outfall Monitoring Report
Railroad Friction Products Corporation, Maxton, North Carolina, Certificate of Coverage Num er.NCG03,
Madam:
nce with General Permit Part II Section B, enclosed please find duplicate signed copies of Railroad Friction Produ(
)r Discharge Outfall Monitoring Report. This report summarizes analytical monitoring of the site's single outfall anc
of January 1, 2015 through June 330, 2015. Below is one issue RPFC would like to discuss with DWQ.
concentrations for all discharge characteristics are below the listed benchmark values. During previous sampling
sampled values were higher that the listed zinc benchmark range of 0.067 mg/L. However, during this sampling F
ipled value was 0.050 mg/L, which is under the benchmark value. As previously communicated to DWQ, RPFC
tuted better housekeeping requirements in order to prevent production material from flowing into the facility draina,
ddition, in September 2014 we installed a StormCeptor unit where storm water drains in back of factory that captur
icles in the storm water to prevent them reaching the drainage creek. Since the measured zinc level is lower than
chmark zinc value and 2014 measured values were trending downward, it appears that the corrective measures
lemented by RFPC are successfully lowering zinc values. RFPC will continue monthly zinc monitoring to confirm I
lysis. Previous results are shown below.
ember 2013: 1.200 mg/L
1 2014: 0.39 mg/L
tember 2014: 0.130 mg/L
)ber 2014: 0.086 mg/L
ember 2014: 0.350 mg/L
wary 2015: 0.050 mg/L
urther implement plans to eliminate any possibility of material reaching creek, we also plan to conduct a week lonc
it in early 2015 in which we will design and implement a system to ensure all reject break shoe material is put in cl
to placing it in the reject materials hopper located in the back of this factory. This will prevent windblown erosion
luct into the drainage creek. Lastly, we are collecting zinc samples of the surrounding area and will considering as
0gher zinc benchmark values if values resume to higher than listed benchmark value.

any questions regarding the enclosed material please call me at 910.844.9739.

Quality Assurance Report
Level II
January 19, 2015
L743045
The data package includes a summary of the analytic results of the quality
control samples required by the SW-846 or CWA methods. The quality control
samples include a method blank, a laboratory control sample, and the matrix
spike/matrix spike duplicate analysis. If a target parameter is outside
the method limits, every sample that is effected is flagged with the
appropriate qualifier in Appendix B of the analytic report.
Method Blank - an aliquot of reagent water carried through the
entire analytic process. The method blank results indicate if
any possible contamination exposure during the sample handling,
digestion or extraction process, and analysis. Concentrations of
target analytes above the reporting limit in the method blank are
qualified with the "B" qualifier.
Laboratory Control Sample - is a sample of known concentration
that is carried through the digestion/extraction and analysis
process. The percent recovery, expressed as a percentage of the
theoretical concentration, has statistical control limits
indicating that the analytic process is "in control". If a
target analyte is outside the control limits for the laboratory
control sample or any other control sample, the parameter is
flagged with a "J9" qualifier for all effected samples.
Matrix Spike and Matrix Spike Duplicate - is two aliquots of an
environmental sample that is spiked with known concentrations of
target analytes. The percent recovery of the target analytes
also has statistical control limits. If any recoveries that are
outside the method control limits, the sample that was selected
for matrix spike/matrix spike duplicate analysis is flagged with
either a "J5" or a "J6". The relative percent difference (%RPD)
between the matrix spike and the matrix spike duplicate
recoveries is all calculated. If the RPD is above the method
limit, the effected samples are flagged with a "J3" qualifier.

Please verify whether Qualitative Monitoring must be performed durittg.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
�obtains approval from the local DWQ Regional Office.

Quality Assurance Report
Level II
December 08, 2014
L736461
The data package includes a summary of the analytic results of the quality
control samples required by the SW-846 or CWA methods. The quality control
samples include a method blank, a laboratory control sample, and the matrix
spike/matrix spike duplicate analysis. If a target parameter is outside
the method limits, every sample that is effected is flagged with the
appropriate qualifier in Appendix B of the analytic report.
Method Blank - an aliquot of reagent water carried through the
entire analytic process. The method blank results indicate if
any possible contamination exposure during the sample handling,
digestion or extraction process, and analysis. Concentrations of
target analytes above the reporting limit in the method blank are
qualified with the "B" qualifier.
Laboratory Control Sample - is a sample of known concentration
that is carried through the digestion/extraction and analysis
process. The percent recovery, expressed as a percentage of the
theoretical concentration, has statistical control limits
indicating that the analytic process is "in control". If a
target analyte is outside the control limits for the laboratory
control sample or any other control sample, the parameter is
flagged with a "J4" qualifier for all effected samples.
Matrix Spike and Matrix Spike Duplicate - is two aliquots of an
environmental sample that is spiked with known concentrations of
target analytes. The percent recovery of the target analytes
also has statistical control limits. If any recoveries that are
outside the method control limits, the sample that was selected
for matrix spike/matrix spike duplicate analysis is flagged with
either a "J5" or a "J6". The relative percent difference (%RPD)
between the matrix spike and the matrix spike duplicate
recoveries is all calculated. If the RPD is above the method
limit, the effected samples are flagged with a "J3" qualifier.

Please verify whether Qualitative Monitoring must be performed during a "representative storm

Qualitative monitoringrequirements 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.

Quality Assurance Report
Level II
L692673
The data package includes a summary of the analytic results of the quality
control samples required by the SW-846 or CWA methods. The quality control
samples include a method blank, a laboratory control sample, and the matrix
spike/matrix spike duplicate analysis. If a target parameter is outside
the method limits, every sample that is effected is flagged with the
appropriate qualifier in Appendix B of the analytic report.
Method Blank - an aliquot of reagent water carried through the
entire analytic process. The method blank results indicate if
any possible contamination exposure during the sample handling,
digestion or extraction process, and analysis. Concentrations of
target analytes above the reporting limit in the method blank are
qualified with the "B" qualifier.
Laboratory Control Sample - is a sample of known concentration
that is carried through the digestion/extraction and analysis
process. The percent recovery, expressed as a percentage of the
theoretical concentration, has statistical control limits
indicating that the analytic process is "in control". If a
target analyte is outside the control limits for the laboratory
control sample or any other control sample, the parameter is
flagged with a "J4" qualifier for all effected samples.
Matrix Spike and Matrix Spike Duplicate - is two aliquots of an
environmental sample that is spiked with known concentrations of
target analytes. The percent recovery of the target analytes
also has statistical control limits. If any recoveries that are
outside the method control limits, the sample that was selected
for matrix spike/matrix spike duplicate analysis is flagged with
either a "J5" or a "J6". The relative percent difference (%RPD)
between the matrix spike and the matrix spike duplicate
recoveries is all calculated. If the RPD is above the method
limit, the effected samples are flagged with a "J3" qualifier.

Madam
ice with General Permit Part II Section B, enclosed please find duplicate signed copies of Railroad Friction Produce

concentrations,for all discharge characteristics were below the listed benchmark values with the exception of zinc <
zinc benchmark range is 0.067 mg/L, but the sampled value was 0.39 mg/L. As previously communicated to DW(
nstituted better housekeeping requirements in order to prevent production material from flowing into facility draina(
is will be intensified and monitored. In addition we are in the process of installing a StormCeptor unit where storr
is in back of factory that will capture any particles in the storm water to prevent them reaching the drainage creek.
Ian to conduct a weeklong team activity in May 2014 in which we will design and implement a system to ensure all
shoe material is put in closed bags prior to placing it in the reject material hopper located in the back of this facto
,revent windblown erosion of product into the drainage creek. RFPC plans to have all above mentioned systems it
than June 2014.
pled PH value was 5.81. This is a problem that we have encountered before, but not since 2011. Then and now
-diately walked around the entire perimeter of the facility in an effort to determine the cause of the low PH reading,
found. We then reviewed the manufacturing process to determine if anything occurred that would have caused 1
E)ading, but nothing was found with this search either. RFPC checked the PH of rainwater from the sampling storr
t was 4.89. Thus, per permit Table 3 of our permit, 4.89 is the lower threshold of the PH benchmark, not 6.0.
