1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites maybe eligible for a waiver of the rain gauge requirement.
' See General Permit text, Table 1, identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
Note: Results must be reported in numerical format. For example, do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -
numerical format. When results are below the applicable limits, they must be reported in the format, "<XX me/L where XX is the numerical value of the
detection limit, reporting limit, etc. in mg/L. Conversely, where fecal coliform results exceed the dilution upper limit, report the result as ">XX".

B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit (MDQ and the laboratory method
reporting limit (MRL)r adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
[CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses.

B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
I The reported value is between the laboratory method detection limit (MDQ and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 251% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
Q-01 Analysis performed outside of method - specified holding time.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LC5 recovery.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
I The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQQ and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
Q-01 Analysis performed outside of method - specified holding time.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
] The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture `content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
I The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
r
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (8511/o or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
Q-01 Analysis performed outside of method - specified holding time.
