Enclosed are the original and a copy of the stormwater monitoring results for the second -half of
2018 for our Willow Springs Lane facility. Our four stormwater outfalls were sampled during a
significant rain event (documentation is attached). On -site measurement of pH was conducted
at Apollo Chemical at the time of sampling. The samples were sent to Meritech, Inc. (Lab
Certification No: 165) for analysis. The samples were tested for TSS, COD, and Oil & Grease.
The Meritech report is appended. Our "Stormwater discharge outfall monitoring report" which
includes pH results, is also appended.
If you need additional information, please contact me.

Enclosed are the original and a copy of the stormwater monitoring results for the first half of
2018 for our Willow Springs Lane facility. Our four stormwater outfalls were sampled during a
significant rain event (documentation is attached). On -site measurement of pH was conducted
at Apollo Chemical at the time of sampling. The samples were sent to Meritech, fnc. (Lab
Certification No: 165) for analysis. The samples were tested for TSS, COD, and Oil & Grease.
The Meritech report is appended. Our "Stormwater discharge outfall monitoring report" which
includes pH results, is also appended.
If you need additional information, please contact me.

Enclosed are the original and a copy of the stormwater monitoring results for the second half of
2017 for our Willow Springs Lane facility. Our stormwater outfalls were sampled during a
significant rain event (documentation is attached). On -site measurement of pH was conducted
at Apollo Chemical at the time of sampling. The samples were sent to Meritech, Inc. (Lab
Certification No: 165) for analysis. The samples were tested for TSS, COD, and Oil & Grease.
The Meritech report is appended. Our "Stormwater discharge outfall monitoring report" which
includes pH results, is also appended.
If you need additional information, please contact me.

Enclosed are the original and a copy of the stormwater monitoring results for the first half of
2017 for our Willow Springs Lane facility. Our four stormwater outfalls were sampled during a
significant rain event (documentation is attached). On -site measurement of pH was conducted
at Apollo Chemical at the time of sampling. The samples were sent to Meritech, Inc. (Lab
Certification No: 165) for analysis. The samples were tested for TSS, COD, and Oil & Grease.
The Meritech report is appended. Our "Stormwater discharge outfall monitoring report" which
includes pH results, is also appended.
If you need additional information, please contact me.

Subject: Storm water Sampling 12,14.2015
Date: Tuesday, December 15, 2015 9:49:43 AM
Attached is the Rainfall record for the Burlington Airport for the Storm Water Monitoring Sample
collected on 14-December-2015, collected from 2:45 — 3:00pm. The rain gauge at the Apollo
Chemical - Burlington Facility measured 0.12 inches at the time of collection.
I have measured the pH of each sample using a calibrated electrode using buffer 4 (Reagents
Lot:7402048 EXP 2/2016), buffer 7 (Reagents Lot: 7403278 EXP 3/2016), and buffer 10 (Reagents
Lot: 7403301 EXP 4/2014). The samples were equilibrated to a temperature of 18.9°C prior to
sampling.
SDO-1: pH 8.9
SDO-2: pH 8.6
SDO-3: pH 8.0
SDO-4: pH 8.7

Re: 2015 Semi -Annual NPDES Stormwater Report for Second Half

Mount Vernon Chemicals, LLC 1 Apollo Chemical - Burlington Facility

Burlington, NC 27215
Enclosed are the original and a copy of the stormwater monitoring results for the second half of
2015 for our Willow Springs Lane facility. Our stormwater outfalls were sampled during a
significant rain event (documentation is attached). On -site measurement of pH was conducted
at Apollo Chemical at the time of sampling. The samples were sent to Meritech, Inc. (Lab
Certification No: 165) for analysis. The samples were tested for TSS, COD, and Oil & Grease.
The Meritech report is appended. Our "Stormwater discharge outfail monitoring report" which
includes pH results, is also appended.
The original report included data for COD for SDO-2 that was slightly above the benchmark
(124 vs 120). The same sample was retested by Meritech, with a value of 87 determined. The
two results (124 and 87) were averaged, and the average 106 is below the benchmark. That
data is reported in this revised report.
If you need additional information, please contact me.

Subject: storm Water Sampling 12.14.2015
Date: Tuesday, December 15, 2015 9:49:43 AM
Attached is the Rainfall record for the Burlington Airport for the Storm Water Monitoring Sample
collected on 14-December-2015, collected from 2:45 — 3:OOpm. The rain gauge at the Apollo
Chemical - Burlington Facility measured 0.12 inches at the time of collection.
I have measured the pH of each sample using a calibrated electrode using buffer 4 (Reagents
Lot:7402048 EXP 2/2016), buffer 7 (Reagents Lot: 7403278 EXP 3/2016), and buffer 10 (Reagents
Lot: 7403301 EXP 4/2014). The samples were equilibrated to a temperature of 18.9°C prior to
sampling.
SDO-1: pH 8.9
SDO-2: pH 8.6
SDQ-3: pH 8.0
SD0-4: pH 8.7

Enclosed are the original and a copy of the stormwater monitoring results for the first half of
2015 for our Willow Springs Lane facility. Our four stormwater outfalls were sampled during a
significant rain event (documentation is attached). On -site measurement of pH was conducted
at Apollo Chemical at the time of sampling. The samples were sent to Meritech, Inc. (Lab
Certification No: 165) for analysis. The samples were tested for TSS, COD, and Oil & Grease.
The Meritech report is appended. Our "Stormwater discharge outfall monitoring report" which
includes pH results, is also appended.
If you need additional information, please contact me.

Burlington, NC 27215
Enclosed are the original and a copy of the stormwater monitoring results for the second half of
2014 for our Willow Springs Lane facility. Our stormwater outfalls were sampled during a
significant rain event (documentation is attached). On -site measurement of pH was conducted
at Apollo Chemical at the time of sampling. The samples were sent to Meritech, Inc. (Lab
Certification No: 165) for analysis. The samples were tested for TSS, COD, and Oil & Grease.
The Meritech report is appended. Our °Stormwater discharge outfall monitoring report" which
includes pH results, is also appended.
If you need additional information, please contact me.

Subject: Stormwater Sample collection far 6-November-2014
Date: Friday, November 07, 2014 8:07:57 AM
Attached is the Rainfall record for the Burlington Airport for the Storm Water Monitoring Sample
collected on 6-November-2014, collected from 12:00 — 12:15pm. The rain gauge at the Apollo
Chemical
Burlington Facility measured the even to be 0.13 inches at the time of collection.
I have measured the pH of each sample using a calibrated electrode using buffer 4 (Reagents
Lot:1231NCA EXP 1/2015), buffer 7 (Reagents Lot: 0124PCA EXP 2/2015), and buffer 10 (Reagents
Lot: 0107PCA EXP 1/2015). The samples were equilibrated to a temperature of 22.1°C prior to
sampling.
SDO-1: pH 7.6
SDO-2: pH 7.5
SDO-4: pH 8.2

Enclosed are the original and a copy of the stormwater monitoring results for the first half of
2014 for our Willow Springs Lane facility. Our four stormwater outfalls were sampled during a
significant rain event (documentation is attached). On -site measurement of pH was conducted
at Apollo Chemical at the time of sampling. The samples were sent to Meritech, Inc. (Lab
Certification No: 165) for analysis. The samples were tested for TSS, COD, and Oil & Grease.
The Meritech report is appended. Our "Stormwater discharge outfall monitoring report" which
includes pH results, is also appended.
If you need additional information, please contact me.
