Please find enclosed copies of our NPDES Storm Water Monitoring reporting forms. The results on
these forms are completed to the best of our knowledge.
These samples were taken during a rainstorm on August 13, 2019. The rainfall from this storm event
was 0.3 inches of rain. The rainfall was measured by a rain gauge manufactured by Taylor Precision
Products, Oak Brook IL 60523. This flow was calculated based on the amount of area draining to the
different outfalls, the amount of build -upon (impervious area), and the total amount of rainfall. Based
on this storm event, we had the following flow from the designated outfalls:
OUT.FALL #
FLOW IN MGD

0.5291

0.5618
As always, we continue our efforts to comply with the limits of our NPDES Storm Water permit.
If you have any additional questions or need addition information, please feel free to contact me at

QUALIFIERS
Project: Monthly
Pace Project No.: 92441399
DEFINITIONS
OF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.

STORWATER PERIATTING
Please find enclosed copies of our NPDES Storm Water Monitoring reporting forms. The results on
these forms are completed to the best of our knowledge.
These samples were taken during a rainstorm on August 13, 2019. The rainfall from this storm event
was 0.3 inches of rain. The rainfall was measured by a rain gauge manufactured by Taylor Precision
Products, Oak Brook IL 60523. This flow was calculated based on the amount of area draining to the
different outfalls, the amount of build -upon (impervious area), and the total amount of rainfall. Based
on this storm event, we had the following flow from the designated outfalls:

0.5291

0.5618
As always, we continue our efforts to comply with the limits of our NPDES Storm Water permit.

QUALIFIERS
Project: Monthly
Pace Project No.: 92441399
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count

MDL- Adjusted Method Detection Limit.
PQL- Practical Quantitation Limit.
RL- Reporting Limit -The lowest concentration value that meets project requirements for quantitative data with known precision and

Please find enclosed copies of our NPDES Storm Water Monitoring reporting forms. The results on
these forms are completed to the best of our knowledge.
These samples were taken during a rainstorm on April 26, 2019. The rainfall from this storm event was
0.23 inches of rain. The rainfall was measured by a rain gauge manufactured by Taylor Precision
Products, Oak Brook IL 60523. This flow was calculated based on the amount of area draining to the
different outfalls, the amount of build -upon (impervious area), and the total amount of rainfall. Based
on this storm event, we had the following flow from the designated outfalls:

As always, we continue our efforts to comply with the limits of our NPDES Storm Water permit.

Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.

Please find enclosed copies of our NPDES Storm Water Monitoring reporting forms. The results on
these forms are completed to the best of our knowledge.
These samples were taken during a rainstorm on June 5, 2019. The rainfall from this storm event was
0.29 inches of rain. The rainfall was measured by a rain gauge manufactured by Taylor Precision
Products, Oak Brook IL 60523. This flow was calculated based on the amount of area draining to the
different outfalls, the amount of build -upon (impervious area), and the total amount of rainfall. Based
on this storm event, we had the following flow from the designated outfalls:

As always, we continue our efforts to comply with the limits of our NPDES Storm Water permit.

QUALIFIERS
Project: Monthly June
Pace Project No.: 92432023
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
NO - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit,
Pace Analytical Services, LLC
5701 Conference Drive
Raleigh, NC 27607
[phone]
POL- Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SVJ846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.

STORMWATER PERMITTING
Please find enclosed copies of our NPDES Storm Water Monitoring reporting forms. The results on
these forms are completed to the best of our knowledge.
These samples were taken during a rainstorm on March 15, 2019. The rainfall from this storm event was
0.31 inches of rain. The rainfall was measured by a rain gauge manufactured by Taylor Precision
Products, Oak Brook IL 60523. This flow was calculated based on the amount of area draining to the
different outfalls, the amount of build -upon (impervious area), and the total amount of rainfall. Based
on this storm event, we had the following flow from the designated outfalls:
OUTFALL#
FLOW IN MGD
1
0.5291

0.5618
As always, we continue our efforts to comply with the limits of our NPDES Storm Water permit.
If you have any additional questions or need addition information, please feel free to contact me at

QUALIFIERS
Project: Monthly
Pace Project No.: 92421682
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
Pace Analytical Services, LLC
6701 Conference Drive
Raleigh, NC 27607
[phone]
PQL- Practical Quantilation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
