the wastewater discharged during the sample period.
Act or"the Act"
The Federal Water Pollution Control Act,also known as the Clean Water Act(CWA),as amended,33 USC 1251,et.
seq.
Annual Average
The arithmetic mean of all"daily discharges"of a pollutant measured during the calendar year. In the case of fecal
coliform,the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system,which is
not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day.However,for purposes of this permit,any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Week
The period from Sunday through the following Saturday.
Calendar Quarter
One of the following distinct periods:January through March,April through June,July through September,and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period.The
Director may designate the most appropriate method(specific number and size of aliquots necessary,the time interval
between grab samples,etc.)on a case-by-case basis. Samples may be collected manually or automatically.Composite
samples may be obtained by the following methods:
(1) Continuous:a single,continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: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
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with
the time intervals between samples determined by a preset number of gallons passing the sampling point.Flow
measurement between sample intervals shall be determined by use of a flow recorder and totalizer,and the
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system,or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a
constant time interval.Use of this method requires prior approval by the Director.This method may only be
used in situations where effluent flow rates vary less than 15 percent.The following restrictions also apply:
> Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
> Influent samples shall not be collected more than once per hour.
