All permits require qualitative monitoring to be performed during a "measurable storm event."
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 DEMLR
Regional Office.

CASE NARRATIVE ONE LAB. NATIONWIDE, �
All sample aliquots were received at the correct temperature, in the proper containers, with the
Cp
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
El
have been corrected for the dilution factor used in the analysis. All radiochemicaf sample results for
solids are reported on a dry weight basis with the exception of tritium, carbon-14 and radon, unless wet
weight was requested by the client. All Method and Batch Quality Control are within established
Ss
criteria except where addressed in this case narrative, a non-conformance form or properly qualified
within the sample results. By my digital signature below, I affirm to the best of my knowledge, all
problems/anomalies observed by the laboratory as having the potential to affect the quality of the data
have been identified by the laboratory, and no information or data have been knowingly withheld that
would affect the quality of the data.

GLOSSARY OF TERMS ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
H
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Abbreviations and Definitions �Tc
MDL
Method Detection Limit,
ND
Not detected at the Reporting Limit (or MDL where applicable). FSS
RDL
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference.
Cn
SDG
Sample Delivery Group.
U
Not detected at the Reporting Limit (or MDL where applicable). s
Sr
Analyte
The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
6
If the sample matrix contains an interfering material, or if concentrations of analytes in the sample are higher than the QC
Dilution
highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value
different than 1 is used in this field, the result reported has already been corrected for this factor.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample
The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
Al
sample. The Original Sample may not be included within the reported SDG.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
SC
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. Ifthere was
no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL"
Result
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (4c)
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sci
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported,
Sample Summary (Ss)
This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Dualifier
Description
J5
The sample matrix interfered with the ability to make any accurate determination; spike value is high.
J-
The associated batch QC was outside the lower control limits; associated data has a potential negative bias.
T8
Sample(s) received pastftoo close to holding time expiration.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
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.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

CASE NARRATIVE ONE LAB. NATIONWIDE.'
IEAll sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times. All MDL (LOD) and RDL (LOG)
values reported for environmental samples have been corrected for the dilution factor used in the F
analysis. All radiochemical sample results for solids are reported on a dry weight basis with the
exception of tritium, carbon-14 and radon, unless wet weight was requested by the client. All Method
and Batch Quality Control are within established criteria except where addressed in this case narrative, Ss
a non-conformance form or properly qualified within the sample results. By my digital signature below, I
affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the
potential to affect the quality of the data have been identified by the laboratory, and no information or
data have been knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS ONE LAB, NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
The information below iS designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Abbreviations and Definitions
MDL
Method Detection Limit.
ND.
Not detected at the Reporting Limit (or MDL where applicable).
RDL
Reported Detection Limit.
Rec.
Recovery.
RPD
Relative Percent Difference,
SDG
Sample Delivery .Group.
U
Not detected at the Reporting Limit (or MDL where applicable).
Analyte
The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes . .
P Y
reported.
If the sample matrix contains an interfering material, or if concentrations of analytes in the sample are higher than the
Dilution
highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value
different than 1 is used in this field, the result reported has already been corrected for this factor.
These are the target % recovery,ranges or % difference value that the laboratoryhas historically determined as normal
Limits
for the method and analyte being reported. Successful OC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample
The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
This column provides a letter andlornumber designation that' corresponds to additional information concerning the result
Qualifier
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.' .
The actual analytical Anal result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state "ND" (Not Detected) or "BDL"
Result
{Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
observed either at sample receipt by the laboratory from the field or during the analytical. process. If present, there will
be a section in the CaseNarrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Control
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material,
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
chain.of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
by sample 1D and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)
This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation andfor analysis.

......... .............--...................-.._-.-_-------__-..... ... _.......................................................... --.... - _ —
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.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

CASE NARRATIVE
ONE LAB. NATIONWIDE. A
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times. All MDL (LOD) and RDL (LOQ)
values reported for environmental samples have been corrected for the dilution factor used in the
analysis. All Method and Batch Quality Control are within established criteria except where addressed
in this case narrative, a non-conformance form or properly qualified within the sample results. By my
digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the
laboratory as having the potential to affect the quality of the data have been identified by the
laboratory, and no information or data have been knowingly withheld that would affect the quality of the
data.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
. ..................................... _ ..._.._.
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.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
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 outfail. 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.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
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.

® Yes ❑ No
Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
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.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

Enclosed please find one original and one copy of Forms SWU-247 and SWU-242 and
the laboratory analytical results for the December 14, 2015 stormwater sample.
Total suspended solids for this sampling event were measured at 212 milligrams/liter
(mg/L) which exceeded the permit Benchmark Value of 100 mg/L. In accordance with
Part I1, Section B of the Permit, this is a Tier Two exceedance. At the Permit requires, an
inspection of the facility was conducted within two weeks of receiving the monitoring
results. Monthly monitoring for all parameters has been implemented and will continue
until three consecutive sample results are below the benchmark values.
If you have questions or require more information, please contact me at [phone].

Enclosed please find one original and one copy of Forms SWU-247 and SWU-242 and
the laboratory analytical results for the May 21, 2015 stormwater sample.
Total suspended solids for this sampling event were measured at 320 milligrams/liter
(mg/L), which exceeded the permit Benchmark Value of 100 mg/L. In accordance with
Part Il, section B of the Permit, this was a Tier One exceedance. As the Permit requires,
a re -inspection of the facility was conducted within two weeks of receiving the
monitoring results. The re -inspection was conducted on June 10, 2015 and did not
identify a specific cause for the exceedance. We have recorded this Tier One response in
our Stormwater Pollution Prevention Plan.
If you have questions or require more information, please contact me at [phone].

Please verify whether Qualitative Monitoring mustbe performed during a "representative storm
event"or "measureable storm event" (requirements vary, depending on the permit).
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.

Explanation of QC Qualifier codes
Qualifier Meaning
TS (ESC) - Additional method/sample information: Sample(s) received past/too
close to holding time expiration.
Qualifier Report information
ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and
as required by most certifying bodies including NELAC. in addition to the EPA qualifiers adopted
by ESC, we have implemented Esc qualifiers to provide more information pertaining to our analytical
results. Each qualifier is designated in the qualifier explanation as either EPA or ESC.
Data qualifiers are intended to provide the ESC client with more detailed information concerning
the potential bias of reported data. Because of the wide range of constituents and variety of
matrices incorporated by most EPA methods,it is common for some compounds to fall outside of
established ranges. These exceptions are evaluated and all reported data is valid and useable
"unless qualified as 'R' (Rejected)."
Definitions
Accuracy - The relationship of the observed value of a known sample to the
true value of a known sample. Represented by percent recovery and
relevant to samples such as: control samples, matrix spike recoveries,
surrogate recoveries, etc.
Precision - The agreement between a set of samples or between duplicate samples.
Relates to how close together the results are and is represented by
Relative Percent Differrence.
Surrogate - Organic compounds that are similar in chemical composition, extraction,
and chromotography to analytes of interest. The surrogates are used to
determine the probable response of the group of analytes that are chem-
ically related to the surrogate compound. Surrogates are added to the
sample and carried through all stages of preparation and analyses.
TIC - Tentatively Identified Compound: Compounds detected in samples that are
not target compounds, internal standards, system monitoring compounds,
or surrogates.

Quality Assurance Report
Level II
L766714
The data package includes a summary of the analytic results of the quality
control samples required by the SN-846 or CWA methods. The quality control
samples include a method blank, a laboratory control sample, and the matrix
spike/matrix spike duplicate analysis. If a target parameter is outside
the method limits, every sample that is effected is flagged with the
appropriate qualifier in Appendix B of the analytic report.
Method Blank - an aliquot of reagent water carried through the
entire analytic process. The method blank results indicate if
any possible contamination exposure during the sample handling,
digestion or extraction process, and analysis. Concentrations of
target analytes above the reporting limit in the method blank are
qualified with the ^B" qualifier.
Laboratory Control Sample - is a sample of known concentration
that is carried through the digestion/extraction and analysis
process. The percent recovery, expressed as a percentage of the
theoretical concentration, has statistical control limits
indicating that the analytic process is "in control". If a
target analyte is outside the control limits for the laboratory
control sample or any other control sample, the parameter is
flagged with a "J4" qualifier for all effected samples.
Matrix Spike and Matrix Spike Duplicate - is two aliquots of an
environmental sample that is spiked with known concentrations of
target analytes. The percent recovery of the target analytes
also has statistical control limits. If any recoveries that are
outside the method control limits, the sample that was selected
for matrix spike/matrix spike duplicate analysis is flagged with
either a "J5" or a --J6". The relative percent difference (4RPD)
between the matrix spike and the matrix spike duplicate
recoveries is all calculated. If the RPD is above the method
limit, the effected samples are flagged with a "J3" qualifier.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event"or "measureable storm event" (requirements vary, depending on the permit).
t Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
I 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
0A inches has occurred. A single stolen 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 permit ee 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.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

Explanation of QC Qualifier Codes
Qualifier Meaning
T8 (ESC) - Additional method/sample information: Sample(s) received past/too
close to holding time expiration.
Qualifier Report Information
ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and
as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted
by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical
results. Each qualifier is designated in the qualifier explanation as either EPA or ESC.
Data qualifiers are intended to provide the ESC client with more detailed information concerning
the potential bias of reported data. Because of the wide range of constituents and variety of
matrices incorporated by most EPA methods,it is common for some compounds to fall outside of
established ranges. These exceptions are evaluated and all reported data is valid and useable
"unless qualified as 'R' (Rejected)."
Definitions
Accuracy - The relationship of the observed value of a known sample to the
true value of a known sample. Represented by percent recovery and
relevant to samples such as: control samples, matrix spike recoveries,
surrogate recoveries, etc.
Precision - The agreement between a set of samples or between duplicate samples.
Relates to how close together the results are and is represented by
Relative Percent Differrence.
Surrogate - Organic compounds that are similar in chemical composition, extraction,
and chromotography to analytes of interest. The surrogates are used to
determine the probable response of the group of analytes that are chem-
ically related to the surrogate compound. Surrogates are added to the
sample and carried through all stages of preparation and analyses.
TIC - Tentatively Identified Compound: Compounds detected in samples that are
not target compounds, internal standards, system monitoring compounds,
or surrogates.

Quality Assurance Report
Level 12
October 22, 2014
L727514
The data package includes a summary of the analytic results of the quality
control samples required by the SW-046 or CWA methods. The quality control
samples include a method blank, a laboratory control sample, and the matrix
spike/matrix spike duplicate analysis. If a target parameter is outside
the method limits, every sample that is effected is flagged with the
appropriate qualifier in Appendix B of the analytic report.
Method Blank - an aliquot of reagent water carried through the
entire analytic process. The method blank results indicate if
any possible contamination exposure during the sample handling,
digestion or extraction process, and analysis. Concentrations of
target analytes above the reporting limit in the method blank are
qualified with the "B" qualifier.
Laboratory Control Sample - is a sample of known concentration
that is carried through the digestion/extraction and analysis
process. The percent recovery, expressed as a percentage of the
theoretical concentration, has statistical control limits
indicating that the analytic process is "in control". If a
target analyte is outside the control limits for the laboratory
control sample or any other control sample, the parameter is
flagged with a "J4" qualifier for all effected samples.
Matrix Spike and Matrix Spike Duplicate - is two aliquots of an
environmental sample that is spiked with known concentrations of
target analytes. The percent recovery of the target analytes
also has statistical control limits. If any recoveries that are
outside the method control limits, the sample that was selected
for matrix spike/matrix spike duplicate analysis is flagged with
either a "J5" or a "J6". The relative percent difference (%RPD)
between the matrix spike and the matrix spike duplicate
recoveries is all calculated. If the RFD is above the method
limit, the effected samples are flagged with a "J3" qualifier.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
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.
l 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) i n which no storm event measuring greater than
t 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 (i-om 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 Re ional Office.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

Qualifier Report Information
ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and
as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted
by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical
results. Each qualifier is designated in the qualifier explanation as either EPA or ESC.
Data qualifiers are intended to provide the ESC client with more detailed information concerning
the potential bias of reported data. Because of the wide range of constituents and variety of
matrices incorporated by most EPA methods,it is common for some compounds to fall outside of
established ranges. These exceptions are evaluated and all reported data is valid and useable
"unless qualified as 'RI (Rejected)."
Definitions
Accuracy - The relationship of the observed value of a known sample to the
true value of a known sample. Represented by percent recovery and
relevant to samples such as: control samples, matrix spike recoveries,
surrogate recoveries, etc.
Precision - The agreement between a set of samples or between duplicate samples.
Relates to how close together the results are and is represented by
Relative Percent Differrence.
Surrogate - Organic compounds that are similar in chemical composition, extraction,
and chromotography to analytes of interest. The surrogates are used to
determine the probable response of the group of analytes that are chem-
ically related to the surrogate compound. Surrogates are added to the
sample and carried through all stages of preparation and analyses.
TIC - Tentatively Identified Compound: Compounds detected in samples that are
not target compounds, internal standards, system monitoring compounds,
or surrogates.

Quality Assurance Report
Level II
L68SS33
The data package includes a summary of the analytic results of the quality
control samples required by the $W-846 or CWA methods. The quality control
samples include a method blank, a laboratory control sample, and the matrix
spike/matrix spike duplicate analysis. If a target parameter is outside
the method limits, every sample that is effected is flagged with the
appropriate qualifier in Appendix B of the analytic report.
Method blank - an aliquot of reagent water carried through the
entire analytic process. The method blank results indicate if
any possible contamination exposure during the sample handling,
digestion or extraction process, and analysis. Concentrations of
target analytes above the reporting limit in the method blank are
qualified with the "B" qualifier.
Laboratory Control Sample - is a sample of known concentration
that is carried through the digestion/extraction and analysis
process. The percent recovery, expressed as a percentage of the
theoretical concentration, has statistical control limits
indicating that the analytic process is "in control If a
target analyte is outside the control limits for the laboratory
control sample or any other control sample, the parameter is
flagged with a "J4" qualifier for all effected samples.
Matrix Spike and Matrix Spike Duplicate - is two aliquots of an
environmental sample that is spiked with known concentrations of
target analytes. The percent recovery of the target analytes
also has statistical control limits. If any recoveries that are
outside the method control limits, the sample that was selected
for matrix spike/matrix spike duplicate analysis is flagged with
either a "J5" or a "J6". The relative percent difference (%RPD)
between the matrix spike and the matrix spike duplicate
recoveries is all calculated. If the RPD is above the method
limit, the effected Bamples are flagged with a "J3" qualifier,
