Notes:
Cutoff Concentration. For each parameter, the arithmetic mean of all analytical sampling results
collected during the first year of the permit shall be calculated for each individual outfall and
compared to the cut-off concentrations listed. If the arithmetic mean is below the specified cut
off concentration for a given parameter, then the facility is not required to continue annual
analytical monitoring for that parameter at the outfall during the term of the permit unless a
significant change in facility operations or configuration occurs. If a cut-off concentration results
in discontinued analytical monitoring at an individual discharge outfall, the permittee is required
to maintain facility operations that ensure the continuation of stormwater runoff quality.
Measurement frequency. Once per year. The facility must perform analytical sampling during
the first full year and last year of the permit term regardless of cut-off concentration conditions.
Analytical results from sampling during the final year of the permit term must be submitted with
the permit renewal application. Failure to monitor storm events in accordance with the specified
frequency shall constitute a violation of this permit.
Sample Location. Samples to be collected at each stormwater discharge outfall (SDO) unless
representative outfall status has been granted. If a facility has multiple discharge locations with
substantially identical stormwater discharges that are required to be sampled, the Permittee may
petition the Director for representative outfall status. If it is established that the stormwater
discharges are substantially identical and the permittee-is granted representative outfall status,
then sampling requirements may be performed at a reduced number of outfalls.
4. For each sampled representative storm event the total precipitation, storm duration, and total
flow must be monitored. Total flow shall be either: (a) measured continuously, (b) calculated
based on the amount of area draining to the outfall, the amount of build-upon (impervious) area,
and the total amount of rainfall, or (c) estimated by the measurement of flow at 20 minute
intervals during the rainfall event (not to exceed three hours).

The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If
only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum
daily discharge." This limitation is identified as "Daily Maximum," in Part I of the permit.
The "monthly average discharge" is defined as the total mass of all daily discharges sampled and/or measured
during a calendar month on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such month. It is therefore, an arithmetic mean found by
adding the weights of the pollutant found each day of the month and then dividing this sum by the number
of days the tests were reported. The limitation is identified as "Monthly Average" in Part 1 of the permit.
The "weekly average discharge" is defined as the total mass of all daily discharges sampled and/or measured
during the calendar week (Sunday - Saturday) on which daily discharges are sampled and measured, divided
by the number of daily discharges sampled and/or measured during such week. It is, therefore, an arithmetic
mean found by adding the weights of pollutants found each day of the week and then dividing this sum by
the number of days the tests were reported. This limitation is identified as "Weekly Average" in Part I of the
permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled and/or measured
during the calendar year on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such year. It is, therefore, an arithmetic mean found by adding
the weights of pollutants found each day of the year and then dividing this sum by the number of days the
tests were reported. This limitation is defined as "Annual Average" in Part I of the permit.
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar month on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured during such
month (arithmetic mean of the daily concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for fecal coliform
bacteria is the geometric mean of the counts for samples collected during a calendar month. This limitation
is identified as "Monthly Average" under "Other Limits" in Part I of the permit.

a.
Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged monthly. It is
determined as the arithmetic mean of the total daily flows recorded during the calendar month.
An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when both the
sample and flow will be representative of the total discharge.
Part 11
Page 2 of 11
The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of dissolved
oxygen required to be available in the effluent prior to discharge averaged over a calendar day. If only one
dissolved oxygen sample is taken over a calendar day, the sample is considered to be the "daily average
concentration" for the discharge. It is identified as "daily average" in the text of Part I.
Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge and
combined proportional to the rate of flow measured at the time of individual sample collection, or
g. A calendar quarter is defined as one of the following distinct periods: January through March, April through
June, July through September, and October through December.
The "maximum daily concentration" is the concentration of a pollutant discharge during a calendar day. If
only one sample is taken during any calendar day the concentration of pollutant calculated from it is the
"Maximum Daily Concentration". It is identified as "Daily Maximum" under "Other Limits" in Part 1 of the
permit.
The "average annual concentration," other than for fecal coliform bacteria, is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar year on which daily discharges are sampled
and measured divided by the number of daily discharges sampled and/or measured during such year
(arithmetic mean of the daily concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average yearly count for fecal coliform
bacteria is the geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as "Annual Average" under "Other Limits" in Part I of the permit.
The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar week (Sunday/Saturday) on which daily
discharges are sampled and measured divided by the number of daily discharges sampled and/or measured
during such week (arithmetic mean of the daily concentration values). The daily concentration value is equal
to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted
by flow value) of all the samples collected during that calendar day. The average weekly count for fecal
coliform bacteria is the geometric mean of the counts for samples collected during a calendar week. This
limitation is identified as "Weekly Average" under "Other Limits" in Part 1 of the permit.
A "continuous flow measurement" is a measure of discharge flow from the facility which occurs continually
without interruption throughout the operating hours of the facility. Flow shall be monitored continually
except for the infrequent times when there may be no flow or for infrequent maintenance activities on the
flow device.
The "quarterly average concentration" is the average of all samples taken over a calendar quarter. It is
identified as "Quarterly Average Limitation" in the text of Part 1 of the permit.

facility is a new source in 40 CFR Part 122.29 (b); or
The alteration or addition could significantly change the nature or increase the quantity of pollutants
discharged. This notification applies to pollutants which are subject neither to effluent limitations in the
permit, nor to notification requirements under 40 CFR Part 122.42 (a) (1).
The alteration or addition results in a significant change in the permittee’s sludge use or disposal practices,
and such alternation, addition or change may justify the application of permit conditions that are different
from or absent in the existing permit, including notification of additional use or disposal sites not reported
during the permit application process or not reported pursuant to an approved land application plan.
Transfers
