Dear Sir or Madam:
Enclosed are the results of our Second Semi -Annual Storm Water Discharge
Outfall Monitoring Report of 2018. We have exceedances for Copper in Outfalls
1, 2 and 3, and exceedances for Zinc at Outfalls 2, 3 and 4. We were granted
relief from the Tiered responses for our Copper and Zinc exceedances in
January of 2015.
Our improvement to the area surrounding the storm drains which report to Outfall
3 has decreased the amount of Suspended Solids at the outfall. We were below
benchmark again for this test, making this the seventh consecutive test under
benchmark. We also completed maintenance of Outfall 3 drainage ditch to
minimize erosion in August of 2017.
If you have questions or concerns please feel free to contact me.

Dear Mr. Moore:
Enclosed are the continued results of our First Semi -Annual Storm Water
Discharge Outfall Monitoring Report of 2016.
The lab who conducted our sample analysis, Pace Analytical, was unable to
obtain a pH sample for the sampling period. I spoke to you on the phone and
you told me we were ok to send this report on June 16, 2016 without the pH as
long as when we have our next rain event we pull pH samples from all outfalls
and submit them at that time.
I have collected stormwater from all outfalls except SDO-1 which had no flow
during this rain event. I tested the pH of each sample using a Scientific
Instruments model no. IQ125 pH meter which was properly calibrated before
each individual reading. We are within the allowable range for pH on all outfalls.
If you have questions or concerns please feel free to contact me.
Respectfully Submitted,

DWR'SECTION
Enclosed are the results of our First Semi -Annual Storm Water Discharge Outfall
Monitoring Report of 2017. We have exceedances for Copper in Outfalls 1, 2
and 3, and exceedances for Zinc at Outfalls 2, 3 and 4. We were granted relief
from the Tiered responses for our Copper and Zinc exceedances in January of
2015.
Our improvement to the area surrounding the storm drains which report to Outfall
3 has decreased the amount of Suspended Solids at the outfall. We were below
benchmark again for this test, making this the fourth consecutive test under
benchmark. We have a plan in place .to complete additional general
maintenance for erosion control around our shipping area to help keep
Suspended Solids to a minimum.
If you have questions or concerns please feel free to contact me.

Dear Mr. Moore:
Enclosed are the results of our Second Semi -Annual Storm Water Discharge
Outfall Monitoring Report of 2016. We have exceedances for Copper in Outfalis
2 and 3, and exceedances for Zinc at Outfalls 2 through 4. We were granted
relief from the Tiered responses for our Copper and Zinc exceedances in
January of 2015. Outfall 1 did not flow during this test period as it has a very
small area which reports to it. We did successfully pull Outfall 1 samples on
January 2, 2017 and will submit those results as soon as possible.
Our improvement to the area surrounding the storm drains which report to Outfall
3 has decreased the amount of Suspended Solids at the outfall. We were below
benchmark again for this test, making this the third consecutive test under
benchmark. We have a plan in place to complete additional general
maintenance for erosion control around our shipping area to help keep
Suspended Solids to a minimum.
If you have questions or concerns please feel free to contact me.
Respectfully Submitted,

Dear Sir or Madam:
Enclosed are the results of our First Semi -Annual Storm Water Discharge Outfall
Monitoring Report of 2016.
The lab who conducted the sample analysis, Pace Analytical, was unable to
obtain a pH reading from our samples this test period. I contacted Mr. James
Moore at the Mooresville Regional Office and he directed me to proceed with the
June 16, 2016 submittal as long as when we had our next rain event we gather a
pH sample from all outfalls and submit the data at that time.
I have collected stormwater from all outfalls except SDO-1 which had no flow
during this rain event. I tested the pH of each sample using a Scientific
Instruments model no. IQ125 pH meter which was properly- calibrated before
each individual reading. We are within the allowable range for pH on all outfalls.
If you have questions or concerns please feel free to contact me.
Respectfully Submitted, geceNSID

Dear Sir or Madam:
Enclosed are the results of our Second Semi -Annual Storm Water Discharge
Outfall Monitoring Report of 2015. We have exceedances for Copper in Outfalls
1, 2 and 3, and exceedances for Zinc at Outfalls 1 through 4. We were granted
relief from monthly monitoring for our Copper and Zinc exceedances in January
of 2015.
Our improvement to the area surrounding the storm drains which lead to Outfall 3
has decreased the amount of Suspended Solids at the outfall. We were below
benchmark for this test.
We continue to maintain a Corrective Action for our exceedances of Copper and
Zinc for all outfalls. We also continue to conduct frequent checks of areas where
materials are stored.
If you have questions or concerns please feel free to contact me.

Enclosed are the results of our September 2014 Storm Water Discharge Outfall
Monitoring Report. We have exceedances for Copper and Zinc in all outfalls. We
also sampled virgin rainwater which was above benchmark in several instances
for Copper and Zinc prior to being affected by ESC. We continue to maintain a
Corrective Action for our exceedances of Copper and Zinc for all outfalls.
We would like to request that we be given permission to return to biannual
sampling. Our testing of virgin rain water has consistently shown that the
rainwater we are receiving is above benchmarks for Copper and Zinc prior to
being effected by ESC property. In some instances, we are essentially filtering
the rainwater as it was testing lower at the Outfalls than it was as virgin rainfall.

Dear Sir or Madam:
Enclosed are the results of our August 2014 Storm Water Discharge Outfall
Monitoring Report. We had no flow during normal work hours this month.
We continue to maintain a Corrective Action for our exceedances of Copper and
Zinc for all outfalls. We plan to continue testing virgin rainwater prior to being
effected by ESC as well. These tests will be conducted each month as we
continue our efforts to reach our Environmental goals. We would appreciate any
assistance you may be able to offer in meeting our goals.
If you have questions or concerns please feel free to contact me.

Dear Sir or Madam:
Enclosed are the results of our July 2014 Storm Water Discharge Outfall
Monitoring Report. All outfalls have exceeded for both Copper and Zinc. It still
remains in our Environmental Management System as an Environmental
Corrective Action Response.
However, we continue to capture virgin rainwater in small plastic pools in the
areas relating to each storm water discharge to.test the concentrations of metals
in the rainwater coming to us from the sky prior to touching our property. Again,
we found in all instances the virgin rainwater we captured were already
exceeding our benchmarks for Copper and Zinc.
Attached you will also find a short comparison analysis on Copper and Zinc
concentrations of each Storm Drain Outfall with its corresponding pool. These
tests will be conducted each month as we continue our efforts to reach our
Environmental goals. We would appreciate any assistance you may be able to
offer in meeting our goals.
If you have questions or concerns please feel free to contact me.

Enclosed are the results of an additional test for May 2014, Storm Water
Discharge Outfall Monitoring Report. All outfalls (1,2,3 & 4) have exceeded
levels for Copper and Outfalls 3 & 4 have exceeded levels for Zinc.
We captured rainwater runoff as it entered the storm drain grate at our shipping
dock which corresponds with SDO 3. We found that Copper and Zinc
concentrations were higher at the drain than it was at the outfall.
We also tested rainwater runoff in our Wet Weather Stream which runs onto the
property from Old Murdock Rd was already exceeding the benchmark for Copper
and was threatening the benchmark for Zinc. We will continue to add additional
rainwater testing as we continue our efforts to reach our Environmental goals.

Dear Sir or Madam:

Enclosed are the results of our May 2014 Test #1 Storm Water Discharge Outfall
Monitoring Report. Outfalls 2, 3 & 4 have exceeded for both Copper and Zinc.
We have also entered it into our Environmental Management System as an
Environmental Corrective Action Response.
However, we captured virgin rainwater in small plastic pools to test the
concentrations of metals in the rainwater coming to us from the sky prior to
touching our property. We found in all instances the virgin rainwater we captured
were already exceeding our benchmarks for Copper and Zinc. These tests will
be conducted each month as we continue our efforts to reach our Environmental
goals. We would appreciate any assistance you may be able to offer in meeting
our goals.
If you have questions or concerns please feel free to contact me.
Respectfully Submitted,

Inspection Summary:
There are 4 stormwater discharge outfalls at this facility. Zinc and copper were all above the bench mark values in 2013
except for copper at SDO-4. The facility did not start the monthly monitoring for the stormweater discharge in compliance
with the permit requirements because of personel turn over at the facility. According to Jan Comer, Vice
President -Human Resource, they will start the monthly requirement starting this month. During the site investigation it
was noted that there was not a secondary containment for the (heat treat oil coolers). Also, It was suggested to sweep
clean the parking lots prior to the sampling events.
