RE: Charlotte Pipe & Foundry Co.
Stormwater Analytical - SW002, SWO04 & SWO05 Tier 2 Monthly Sampling
Stormwater Permit Number NCS000040
Sampling Timeframe: August 2018
Charlotte Pipe and Foundry (Charlotte Pipe) is sending this letter to
NCDENR in regard to monthly Tier II sampling requirements for SW002,
SWO04 and SW005.
For the month of August 2018, URS, our contractor, was unable to collect
stormwater samples from outfalls SW002, SWO04 and SWO05 due to weather
events either occurring outside reasonable working hours or not qualifying
due to the 72 hour time lapse required between rain events.
As required in Tier If of the Stormwater Plan, Charlotte Pipe will continue to
monitor outfalls SW002, SWO04 and SWO05 until such time as the site can
demonstate three consecutive samples that are below the benchmark values.
Please contact Jenny Pappalardo at [phone] or David Waggoner at
[phone] if you have any questions or need any additional information.
Sincerely,

AECOM Project No. 60401 141
To whom it may concern
AECOM Technical Services of North Carolina, Inc. (AECOM) performs stormwater compliance
monitoring for Charlotte Pipe and Foundry (CP&F) at the facility listed above. This monitoring includes
semi-annual collection and analysis of stormwater samples and submittal of associated Discharge
Monitoring Reports (DMRs) and Qualitative Monitoring Reports (QMRs). The DMRs and QMRs are
submitted in accordance with storm water discharge permit number NCS000040. Additionally, monthly
samples are collected at selected outfalls to comply with their associated Tier II status.
In August of 2018, AECOM was unable to collect stormwater samples from permitted outfall locations
SWO02, SWO04 and SWO05, as well as upgradient outfalls SWOIOR and SWO03, which are
sampled to net analytical concentrations against permitted outfalls SWO02 and SWO04, respectively.
AECOM made several attempts to collect the monthly round of stormwater samples from the
permitted and upgradient outfalls before the end of August 2018, but weather events either occurred
outside reasonable working hours or did not qualify due to the 72 hour time lapse required between
rain events or a greater than 10-how' duration between stop/start of precipitation. Therefore, a monthly
sampling event was not reported for CP&F to DWQ for August 2018.
If you have any questions or need additional information, please do not hesitate to contact us

Stormwater Analytical - SW002, SW004 & SW005A Tier 2 Monthly Sampling
Stormwater Permit Number NCS000040
Sampling Timeframe: July 2018
Please find attached the Discharge Monitoring Report (DMR) for Charlotte
Pipe & Foundry for monthly sampling conducted in July 2018.
We have added monthly monitoring for SW002 due to the exceedance of
benchmark values as this outfall location. It is important to note, these
exceedances occurred during a time when construction at the railroad made
upstream outfall location SWO10 inaccessible; therefore, we were not able to
prepare netting calculations for this outfall. During the July 2018 monthly
sampling, the concentration of COD was unusually high. We have not
previously conducted a netting calculation for COD since we don't typically
exceed the benchmark, but if we do net for the July sampling the reportable
concentration would have been 203 mg/L (257 mg/L - 54 mg/L), which
would have been below the benchmark value.
Please contact Jenny Pappalardo at [phone] or David Waggoner at

Please find attached the Discharge Monitoring Reports (DMRs) for Charlotte
Pipe & Foundry for sampling conducted in the February 2018 - July 2018
timeframe.
In the sampling event conducted in March 2018, our contractor was unable to
retrieve a sample from the requested new SWO05 location. This outfall
location receives minimal flow.
In addition, due to construction upstream of Charlotte Pipe, the upstream
outfall SWO10 has no flow; thus, no netting was able to be taken on Outfall
SWO02 to determine actual contributions from Charlotte Pipe. A new
upstream sampling point will need to be determined.
Please contact Jenny Pappalardo at [phone] or David Waggoner at
[phone] if you have any questions or need any additional information.

To whom it may concern:
AECOM Technical Services of North Carolina, Inc. (AECOM) performs stormwater compliance
monitoring for Charlotte Pipe and Foundry (CP&F) at the facility listed above. This monitoring includes
semi-annual collection and analysis of stormwater samples and submittal of associated Discharge
Monitoring Reports (DMRs) and Qualitative Monitoring Reports (QMRs). The DMRs and QMRs are
submitted in accordance with storm water discharge permit number NCS000040. Additionally, monthly
samples are collected at selected outfalls to comply with their associated Tier II status. The attached
DMRs and QMRs represent results of the semi-annual monitoring event conducted on March 6, 2018.
As explained in the attached DMR, flow was not observed at outfall SWO10, the upgradient sampling
location in associated with permitted outfall SW002. Thus, net deductions could not be calculated to
determine the actual contributions from deriving outfall SW002. The likely cause of the conditions
observed at outfall S WO10 can be attributed to the construction/redevelopment of the adjacent property to
the cast in conjunction with the new Norfolk Southern rail spur being installed. In the meantime,
AECOM and CP&F will determine an appropriate upgradient sampling location to adequately determine
contributions from outfall SW002.
If you have any questions or need additional information, please do not hesitate to contact us.

RE: Charlotte Pipe & Foundry Co.
Stormwater Analytical - SWO04 & SWO05A Tier 2 Monthly Sampling
Stormwater Permit Number NCS000040
Sampling Timeframe: January 2018
Charlotte Pipe and Foundry (Charlotte Pipe) is sending this letter to
NCDENR in regard to monthly Tier II sampling requirements for SWO04 and
SW005.
For the month of January 0218, URS, our contractor, was unable to
collect stormwater samples from outfalls SWO04 and SWO05 due to
weather events either occurring outside reasonable working hours or
not qualifying due to the 72 hour time lapse required between rain
events.
As required in Tier II of the Stormwater Plan, Charlotte Pipe will continue to
monitor outfalls SWO04 and SWO05 until such time as the site can
demonstate three consecutive samples that are below the benchmark values.
Please contact Jenny Pappalardo at [phone] or David Waggoner at
[phone] if you have any questions or need any additional information.
Sincerely,
Jenny L. Pappalardo

to whom it may concern
AECOM 'technical Services of North Carolina, Inc. (AECOM) performs stormwater compliance
monitoring for Charlotte Pipe and Foundry (CP&I') at the facility listed above. This monitoring includes
semi-annual collection and analysis of stormwater samples and submittal of associated Discharge
Monitoring Reports (DMRs) and Qualitative Monitoring Reports (QMRs). The DMRs and QMRs are
submitted in accordance with storm water discharge permit number NCS000040. Addtionally, monthly
samples are collected at selected outfalls to comply with their associated "Pier If status.
In January of 2018, AECOM was unable to collect stormwater samples from permitted outfall location
SWO04 as well as upgradient outfall SW003, which is sampled to net analytical concentrations against
permitted outfall SW004. AECOM made several attempts to collect the monthly round of stormwater
samples from the permitted and upgradient outfalls before the end of January 2018, but weather events
either occurred outside reasonable working hours or did not qualify due to either the 72 hour time lapse
required between rain events or a greater than 10-hour duration between stop/start of precipitation.
Therefore, a monthly sampling event was not reported for CP&F to DWQ for January 2018.
Ifyou have any questions or need additional information, please do not hesitate to contact us

Stormwater Analytical - SWO04 & SWO05 Tier 2 Monthly Sampling
Stormwater Permit Number NCS000040
Sampling Timeframe: July 2017
Charlotte Pipe and Foundry (Charlotte Pipe) is sending this letter to
NCDENR in regard to monthly Tier II sampling requirements for SWO04 and
SW005.
For the month of July 2017, URS, our contractor, was unable to collect
stormwater samples from outfalls SWO04 and SW005 due to weather
events either occurring outside reasonable working hours or not
qualifying due to the 72 hour time lapse required between rain events.
As required in Tier II of the Stormwater Plan, Charlotte Pipe will continue to
monitor outfalls SWO04 and SWO05 until such time as the site can
demonstate three consecutive samples that are below the benchmark values.
Please contact Jenny Pappalardo at [phone] or David Waggoner at
[phone] if you have any questions or need any additional information.

To whom it may concern:
AECOM Technical Services of North Carolina, Inc. (AECOM) performs stormwater compliance
monitoring for Charlotte Pipe and Foundry (CP&I') at the facility listed above. This monitoring includes
semi-annual collection and analysis of stormwater samples and submittal of associated Discharge
Monitoring Reports (DMRs) and Qualitative Monitoring Reports (QMRs). The DMRs and QMRs are
submitted in accordance with storm water discharge permit number NCS000040. Addtionally, monthly
samples are collected at selected outfalls to comply with their associated Tier II status.
In July of 2017, AECOM was unable to collect stormwater samples from permitted outfall location
SWO04 and SWO05 as well as upgradient outfall SW003, which is sampled to net analytical
concentrations against permitted outfall SW004. AECOM made several attempts to collect the monthly
round of stormwater samples from the permitted and upgradient outfalls before the end of July 2017, but
weather events either occurred outside reasonable working hours or did not qualify due to the 72 hour
time lapse required between rain events. Therefore, a monthly sampling event was not reported for CP&P
to DWQ for July 2017.

AECOM Technical Services of North Carolina (AECOM) is pleased to submit the attached
Stormwater Discharge Monitoring Reports (DMRs) and Qualitative Monitoring Reports (QMRs)
to Charlotte Pipe and Foundry for stormwater samples collected on February 15, 2017. The
DMRs summarize the laboratory analytical results and storm parameters in accordance with
storm water discharge permit number NCS000040. It should be noted, however, that due to
construction activities at 630 Summit Avenue, no flow was observed in outfall SWO10. Thus, an
upgradient sample was unavailable for collection to net against laboratory results for sample
collected from outfall SW002.
Please sign the attached documents and mail the original and one additional copy to:

RE: Charlotte Pipe & Foundry Co.
Stormwater Analytical - SW004 Tier 2 Monthly Sampling
Stormwater Permit Number NCS000040
Sampling Timeframe: August 2016
Charlotte Pipe and Foundry (Charlotte Pipe) is sending this letter to
NCDENR in regard to monthly Tier lI sampling requirements for SW004.
For the month of August 201.6, URS, our contractor, was unable to
collect stormwater samples from outfall SW004 due to no qualifying
rain event occurring at the subject property during reasonable working
hours.
As required in Tier 1I of the Stormwater Plan, Charlotte Pipe will continue to
monitor outfall SW004 until such time as the site can demonstate three
consecutive samples that are below the benchmark values.
Please contact Jenny Pappalardo at [phone] or David Waggoner at
[phone] if you have any questions or need any additional information.

RE: Charlotte Pipe and Foundry Company
Stormwater Permit Number NCS000040
Sampling Timeframe: February 2016 - July 2016 (Year 7, Period 2)
Charlotte Pipe and Foundry (Charlotte Pipe) is sending this letter to
NCDENR in regard to sampling requirements for Year 7, Period 2 of
Stormwater Permit Number NCD000040.
Unfortunately for the February 2016 - July 2016 timeframe, URS, our
contractor, was unable to collect the comprehensive round of
stormwater samples from the permitted and upgradient outfalls. Per
URS, weather events either occurred in short timeframes that did not
allow time for the comprehensive site -wide sampling, occurred outside
reasonable working hours, or did not qualify due to the 72 hour time
lapse required between rain events.
URS is scheduled to perform the comprehensive monitoring for the
next qualifying rain event and we will submit the appropriate
paperwork to DWQ in a timely manner.
Please see attached the monthly new motor oil usage.
Please contact Jenny Pappalardo at [phone] or David Waggoner at
[phone] if you have any questions or need any additional information.

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."

Stormwater Analytical - SWO04 Tier 2 Monthly Sampling
Stormwater Permit Number'NCS000040__''y
Sampling Timeframe: March 2016
Charlotte Pipe and Foundry (Charlotte Pipe) is sending this letter to
NCDENR in regard to monthly Tier II sampling requirements for SW004.
For the month of March 2016, URS, our contractor, was unable to
collect stormwater samples from outfall SWO04 due to no qualifying
rain event occurring at the subject property during reasonable working
hours.
As required in Tier II of the Stormwater Plan, Charlotte Pipe will continue to
monitor outfall SWO04 until such time as the site can demonstate three
consecutive samples that are below the benchmark values.
Please contact Jenny Pappalardo at [phone] or David Waggoner at

Dear Ms. Pappalardo:
URS Corporation — North Carolina, an AECOM company (URS) is submitting this letter
correspondence to Charlotte Pipe and Foundry regarding the required monthly samples from
storm water outfall SWO04 at the address listed above (subject property). URS reviewed local
weather forecast and rainfall data during the month of March 2016, and found no instances
where a qualifying rain event occurred at the subject property during reasonable working hours.
For purposes of this letter, URS is defining reasonable working hours as daylight hours during a
weekday, as serious safety concerns arise during storm water sampling at night, and teams are
unable to expeditiously mobilize on a weekend to effectively capture adequate data. URS
recently perfonned the comprehensive storm water sampling event at the subject property on
April 12, 2016 and are currently awaiting laboratory results to generate the associated the
Discharge Monitoring Report (DMR).
Thank you for your time and consideration. If you have any questions, please do not hesitate to
call.
Sincerely,

RE: Charlotte Pipe & Foundry Co.
Stormwater Analytical - SWO04 Tier 2 Monthly Sampling
Stormwater Permit Number NCS000040
Sampling Timeframe: July 2015
Charlotte Pipe and Foundry (Charlotte Pipe) is sending this letter to
NCDENR in regard to monthly Tier II sampling requirements for SWO04 and
semi-annual Yr6-P2 sampling for SW005.
For the month of July 2015, URS, our contractor, was unable to collect
stormwater samples from outfall SWO04 due to drought conditions in the
area.
With the new outfall location for SW005, flow is only present in heavy rain
conditions; thus, no sample could be collected during the facility -wide semi-
annual sampling event that was conducted in June 2015. Plans were to make
another attempt at outfall SWO05 during the monthly July sampling for
SW004. Due to the drought conditions, this was not possible.
As required in Tier 11 of the Stormwater Plan, Charlotte Pipe will continue to
monitor for all required parameters until such time as the site can
demonstate three consecutive samples that are below the benchmark values.
Please contact Jenny Pappalardo at [phone] or David Waggoner at
[phone] if you have any questions or need any additional information.

RE: Charlotte Pipe & Foundry Co.
Stormwater Analytical - SWO04 & SWO05 Tier 2 Monthly Sampling
Sampling Timeframe: July 2014
Please find attached the Discharge Monitoring Reports (DMRs) for Charlotte
Pipe & Foundry for sampling conducted in July 2014 for SWO04 and SWO05.
As discussed with Mr. Ken Pickle on July 10, 2014 and with Mr. Erich
Schweiber and Mr. Samar Bou-Ghazale during a site visit on August 6th, a
sample was not taken in June 2014 due to their not being a representative
storm event that URS could mobilize to and take stormwater samples.
During the August 6 site visit, Mr. Schweiber and Mr. Bou-Gharale agreed
that the current location of SWO05 is a road drain and is not a representative
sample of our facility. With this determination, they did request that we
sample a Stormwater basin at the guardhouse located beside Gate #2 for
SWO05 on future sampling events, but said that this sampling could go back
to being senu-annual instead of monthly. This July sampling was conducted
prior to this determination; therefore, results are included in this submittal.
Please contact Jenny Pappalardo at [phone] or David Waggoner at
[phone] if you have any questions or need any additional information.

Dear Ms. Pappalardo:
URS Corporation — North Carolina (URS) is pleased to submit the attached Stormwater Discharge
Monitoring Reports (DMRs) and Qualitative Monitoring Reports (QMRs) to Charlotte Pipe and
Foundry for stormwater samples collected on July 21, 2014. The DMRs summarize the laboratory
analytical results and storm parameters in accordance with the individual storm water discharge permit
number NCS000040.
It should be noted that since the July 2014 storm water sampling, Charlotte Pipe has received approval
from the NCDENR Storm Water Services to begin collecting outfall SW-005 on a semi-annual basis
again (instead of monthly) and to collect samples by the guard gate inside the facility instead of the
current location. However, since a sample was collected for the month of July 2014, the results are
included in the attached DMRs and QMRs.
Please sign the attached documents and mail the original and one additional copy to:

Sampling Timeframe: February 2013 —July 2013
Please find attached the Discharge Monitoring Reports (DMRs) for Charlotte
Pipe & Foundry for sampling conducted in the February — July 2013
timeframe.
Please note that a sample was not collected from SWO01 as the creek has
breached the outfall due to the considerable rainfall we have had this
quarter. Thus, it was not safe to access the creek making the outfall location
inaccessible.
Please contact Jenny Pappalardo at [phone] or David Waggoner at
[phone] if you have any questions or need any additional information.

SWO04 Zinc Benchmark Exceedance
Dear Mr. Khan:
In follow-up to a phone conversation with Ken Pickle, NCDEMLR Stormwater -
Raleigh on Thursday, July 10, 2014,1 am submitting this written notification that
we have exceeded the benchmark value for Zinc from_SW004 on four occasions
since our delay of tiers has expired.
We have implemented several significant BMPs over the past several years to
reduce concentrations of regulated parameters in our Stormwater. These include,
but are not limited to:
• Installation of a Waste Storage Building to cover our waste piles;
• Installation of sump pumps in our scrap storage area and charging system
pits which pump rail water to our on -site water treatment plant for
recycling;
• Placement of covers on outside baghouse collection bins to prevent run-off
to the storm drains;
• Routine sweeping of facility grounds;
• Vacuuming of multiple storm drains;
• Weekly 5S departmental cleaning of outside areas;
• Monthly inspections of material storage areas; and
• Quarterly visual and housekeeping inspections of the site.

PIPE AND FOUNDRY COMPANY SWP SECTION
MOORESVILLE REGIONAL OFFICE
Please accept the attached Discharge Monitoring and Qualitative Monitoring Reports for
the Charlotte Pipe and Foundry site located in Charlotte, Mecklenburg County, North
Carolina. This data submission fulfills the site's requirements for Year 1 Period 2 under
permit number NCS000040.
Please note that samples were collected from storm water outfalls SW001 and SWO02
only. Due to the short duration of the storm event on July 19, 2010, representative
samples from the remaining permitted locations, including SW004, SW005, SW006, and
SWO07 could not be collected. Further attempts to redo the sampling event while staying
within the confines of a representative event were unsuccessful before the end of the
sampling period date, which was July 31, 2010.
Charlotte Pipe and Foundry will strive to fully complete the storm water sampling as
stated in the period for the upcoming period (Year 2, Period 1). We appreciate your
understanding in this matter.
Sincerely,
