REFERENCE: Storm Water Discharge Outfall Monitoring Report —Amended Copy
Railroad Friction Products Corporation, Maxton, North Carolina, Certificate of Coverage Number NCG030108
Dear Sir or Madam:
In accordance with General Permit Part II Section B, enclosed please find duplicate amended signed copies of Railroad Friction Products (RFPC)
Storm water Discharge Outfall Monitoring Report. The amended portion of this report is included in section 2 below (detailing copper
exceedances of benchmark values) and basically includes information detailing that RFPC was granted regulatory relief for copper exceedances.
The original 2nd half 2019 DMR mailed out December 31, 2019 did not include the information regarding the regulatory relief for copper. This is
the only change from this amended DMR compared to the original DMR.
This report summarizes analytical monitoring of the site's single outfall and covers the period of July 1, 2019 through December 31, 2019. Below
are three issues RFPC wants to make DWQ aware of.'
1. The concentration for zinc remains above listed benchmark value of 0.126 mg/L. During some previous sampling periods zinc sampled
values were higher that the listed zinc benchmark range of 0.126 mg/L. The sampling value for first half 2019 was 0.144 mg/L. The
sampling value for second half 2018 was 0.249 mg/L. This monitoring period, the zinc sampling value was 0.333 mg/L. This reoccurring
zinc over benchmark value has been communicated to DWQ. In a letter issued from NCDEQ to RFPC dated May 25, 2018, RFPC was
granted regulatory relief in the form of a collapsed Tier2-Tier 3 response, and RFPC may resume the permitted specified semi-annual
analytical monitoring at our facility. RFPC continues to implement actions to mitigate exposure of storm water to materials. For example,
RFPC built a building to house the open top reject lined hoppers that holds loose reject material. This building blocks windborne dust from
the reject hopper being blown to adjacent facility drainage creek. RFPC has also instituted better housekeeping requirements in order to
prevent production material from flowing into the facility drainage creek. In addition, RFPC has installed a StormCeptor unit where storm
water drains in back of factory that captures any particles in the storm water to prevent them reaching the drainage creek. Based on the
regulatory relief granted in the May 25, 2018 letter, RFPC stopped monthly zinc monitoring.
Previous semi-annual DMR at our SDO results are shown below.
November 2013: 1.200 mg/L
April 2014: 0.390 mg/L
SWU-245-033
Page 1

September 2014: 0_130 mg/L
October 2014: 0.086 mg/L
November 2014: 0.350 mg/L
January 2015: 0.050 mg/L
November 2015: 0.129 mg/L
March 2016: 0.144 mg/L
December 2016: 0.181 mg/L
May 2017: 0.169 mg/L
March 2018: 0.108 mg/L
December 2018: 0.249 mg/L
February 2019: 0.144 mg/L
2. The concentration for copper is above the listed benchmark value of 0.010 mg/L. The last exceedance was sampling value for first half
2018 - 0.0154 mg/L. Per our permit, this exceedance triggers Tier 1 requirements. In a letter issued from NCDEQ to RFPC dated May 25,
2018, RFPC was granted regulatory relief for copper in the form of a collapsed Tier2-Tier 3 response, which means RFPC can continue the
permitted specified semi-annual analytical monitoring at our facility if Tier II status is obtained (which will occur if 1st half 2020 copper
sampling value exceeds benchmark value). RFPC is currently at Tier I status, which does not require monthly monitoring for copper.
RFPC immediately conducted an inspection of the facility and found no obvious causes for copper exceedance, but we suspect the copper
may be deriving from the various ductwork and other metal structures on our factory roof. Even though it is not required, RFPC has
started monthly monitoring for copper in the stormwater outfall and the rainwater flowing from roof downspouts from the factory roof
during rainstorms (assuming such rainstorms occur during the month).
Previous semi-annual DMR at our SDO results are shown below.
February 2013: BDL <0.020 mg/L
November 2013: 0.025 mg/L
April 2014: BDL <0.020 mg/L
September 2014: BDL <0.020 mg/L
October 2014: BDL <0.020 mg/L
November 2014: BDL <0.020 mg/L

November 2015: BDL <0.010 mg/L

December 2016: BDL <0.010 mg/L
May 2017: BDL <0.0148 mg/L
March 2018: 0.0154 mg/L
December 2018: <0.01mg/L
S W U-245-031308

February 2019: <0.01mg/L .
Sampled PH value was 5.82. This is a problem that we have encountered before, but not since 2014. Then and now, we immediately
walked around the entire perimeter of the facility to determine the cause of the low PH reading, but none was found. We then reviewed
the manufacturing process to determine if anything occurred that would have caused the low PH reading, but nothing was found with this
search either. RFPC will check PH again in stormwater sample in January 2020 and compare to collected rainwater PH and advise results.

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outran.
2 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.
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 list of the total toxic organic compounds used -and the other -elements fiste ' d 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."

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

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.
