NPDES Permit NCG510000
PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events.These samples shall be
representative of the wastewater discharged during the sample period.
3/Week
Samples are collected three times per week on three separate calendar days.These samples shall be representative of
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.
Page 8 of 19

NPDES Permit NCG510000
Permittees with wastewater treatment systems whose detention time<24 hours shall collect effluent grab
samples at intervals of no greater than 20 minutes apart during any 24-hour period.
Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent
grab samples at least every six hours;there must be a minimum of four samples during a 24-hour sampling
period.
Continuous flow measurement
Flow monitoring that occurs 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.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling.For pollutants measured in units of mass,the"daily discharge"is calculated as
the total mass of the pollutant discharged over the day.For pollutants expressed in other units of measurement,the
"daily discharge"is calculated as the average measurement of the pollutant over the day.(40 CFR 122.2;see also
"Composite Sample,"above.)
Daily Maximum
The highest"daily discharge"during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling.If sampling is required for all seven days of the week for any permit parameter(s),that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
