Dear Peiniittee:
DIVISION OF WATER QUALITY
The office is conducting a survey of the methods used by various NPDES
permitted facilities in the Fayetteville Region to collect "composite" samples and
some other general information. The goal of this survey is to draw attention to the
importance of proper sampling and to remind you of NPDES peuuit conditions as
well as provisions of administrative code for Surface Water Monitoring &
Reporting.
Attached please find an excerpt from a typical NPDES permit that
describes "Types of Samples" and a copy of Administrative Code Section: 15A
NCAC 2b .0500 - Surface Water Monitoring: Reporting (key portions of this
document have been flagged for your convenience).
Please provide the requested information to this office on or before
October 15. 1999 (a self-addressed return envelope is enclosed for your
convenience).
If you have any questions or comments, please do not hesitate to contact
me at 910-486-1541.
Sincerely,
Belinda S. Henson

A 1 V1'01 .UZuU - 6 UKF'ACE WATER MONITORING: REPORTING
.0501 PURPOSE
The purpose of this Section is to .set forth the requirements of the Environmental Management Commission
for monitoring and reporting the quantity and quality of wastewater discharges to, and their effects upon, the
water resources of the state.
History Note: Statutory Authority G.S. 143-215.64; 143-215.68;
E . February 1, 1976,
Amended E . December 1, 1984.
.0502 SCOPE
This Section shall apply to all persons subject to the provisions of G.S. 143-215.1.
History Note: Statutory Authority G.S. 143-215.64; 143-215.68;
Ef. February 1, 1976.
.0503 DEFINITIONS
Unless the context otherwise requires, the terms used herein shall be as defined in G.S. 143-213 and as
follows:
(1) "Biological monitoring" shall mean the sampling or testing of the biological integrity of surface waters
and measurements of impacts including accumulations of pollutants in tissue, toxicity monitoring, and
characterization of instream biological populations.
(2) "Classified water pollution control facility" means a treatment works classified by the Water Pollution
Control System Operator Certification Commission pursuant to Chapter 90A of the North Carolina
General Statutes as class I, class 11, class III, or class IV facility, or such other classifications as the
Water Pollution Control System Operator Certification Commission mayhereafter adopt.
(3) "Commercial laboratory" means any laboratory which analyzes water samples for a fee.
(4) "Composite sample" means: a sample gathered over a 24 hour period by continuous sampling or
combining grab samples in such a manner as to result in a total sample which is representative of the
wastewater discharge during the sample period. This sample may be obtained by methods given
below, however, the Director may designate the most appropriate method, number and size of aliquots
• necessary and the time interval between grab samples on a case -by -case basis. Samples may be
collected manually or automatically.
(a) tinuous a single, continuous sample collected over a 24 hour period proportional to the rate of
flow.
(b) Constant timeLvariable 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
(c) 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
(d) Constant time/constant volume - a series .of grab samples of equal volume collected over a 24-hour
period at a constant time interval. This method may be used in situations where effluent flow rates
vary less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes
apart during any 24 hour period and must be of equal size and of no less than 100 milliliters. Use
of this method requires prior approval by the Director.
(5) "Daily" means every day on which a wastewater discharge occurs except Saturdays, Sundays and legal
holidays unless otherwise specified by the Director.
(6) "Design flow" means the average daily volume of wastewater which a water pollution control facility
was designed, approved and constructed to treat.
