Bioassay Compliance Inspection
Permit No. NC0003719
DAK Americas LLC — Fayetteville
Cumberland County
Dear Mr. Allbright:
Enclosed you will find a copy of the Bioassay Compliance Inspection report for the inspection
conducted on November 6, 2012. The inspection included the same objectives as that of a
routine Compliance Evaluation Inspection plus an Aquatic Toxicity (AT) test to evaluate the
acute biological effect of the facility's discharge on test organisms. As part of the inspection, a
tour of the Wastewater Treatment Plant was conducted. All observations and a requirement are
in Part D: Summary of Findings/Comments of this inspection report. On November 6, a24-hour
composite sample was collected by DAK (using DAK sampling equipment) at the effluent box
that combined Outfalls 001 and 002 for the Acute Fathead Minnow (Pimephales promelas)
toxicity analysis. This sampling event satisfied DAK's NPDES Whole Effluent Toxicity (WET)
requirement for the fourth quarter of 2012. The sample was split and sent to the following two
laboratories: DAK's commercial WET laboratory (Meritech) and Division of Water Quality
Aquatic Toxicology Unit, located on Reedy Creek Road in Raleigh. The WET testing resulted in
a "Pass" by both laboratories, indicating that the effluent would not be predicted to have water
quality impacts on the receiving water.
As a result of the site inspection and a file review, the following deficiency: was noted.
According to DAK's NPDES permit and to 15A NCAC 02B .0503, a 24-hour composite sample

that uses the constant time/constant volume method must have grab samples of no less than 100
milliters in size. Based upon the approximate sample volume (3.5 L) collected on November 6th,
that included a 24-hour period of sampling at a frequency of four times per hour, each aliquot
volume was calculated to be approximately 35 mL. As an example for future consideration, 100
mL aliquots at four samples per hour would yield 9,600 mL (2.5 gallons). However, this also
appeared to be the facility's 24-hour sample container size. So as to be in agreement with the
two regulations (above mentioned), and so that you do not risk the possibility of overflowing
your current sample container, the sampling frequency may be reduced to a minimum of 20
minutes intervals.
Please respond to this letter in writing within 30 calendar days of receipt. Your response
should include your intended action for keeping with the two regulations. This office requires
that the deficiency as described above be properly resolved. If you have any questions, please
contact me or Dale Lopez at [phone].

class I, class II, class III, or class IV facility, or such other classifications as the Water Pollution Control
System Operator Certification Commission may hereafter 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) ' Continuous - a single, continuous sample collected over a 24 hour period proportional to the rate of
flow.
(b) Constant time/variable volume - a series of grab samples collected at equal time intervals over a 24
hour period of discharge and combinedproportional. 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_effluentflow rates
vary less than 15 percent. The grab samples shall be taken at intervals ofno 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.
(7) "Design treatment capability" means a water pollution control facility's capacity to achieve a specified degree
of reduction in waste constituents.at a specified design flow, to meet specified limits or removal efficiencies.
(8) "Director" means the Director of the Division of Environmental Management, Department of Environment,
Health, and Natural Resources.
(9) "Division" means the Division of Environmental Management; Department of Environment, Health, and
Natural Res ources .
(10) "Domestic wastewater" means water -carried human wastes together with all other water -carried wastes
normally present in wastewater from non -industrial processes.
(11) "Downstream" means locations in the receiving waters below (downstream of) a point of waste discharge
after a reasonable opportunity for dilution and mixture as specified in the Commission's '.'Rules, Regulations,
Classifications and Water Quality Standards Applicable to the Surface Waters ofNorth-Carolina."
(12) "Effluent" means wastewater discharged following all treatment processes from a water pollution control
facility or other point source whether treated or untreated.
(13) "Flow" means the total volume of wastewater discharged from an outlet during any given period.
(14) "Grab sample" means an individual sample collected instantaneously. Samples of this type must be
representative of the discharge or the receiving waters.

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 periodfrom 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 nil in
such a mariner 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
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.
➢ 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. The :'daily discharge" concentration
comprises the mean concentration for a 24-hour sampling period as either a composite sample concentration or the
arithmetic mean of all grab samples collected during that period. (40 CFR 122.2)
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 sevendays of the week for any permit
parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWQ or "the Division"
The Division of Water Quality, Department of Environment and Natural Resources.
EMC
The North Carolina Environmental Management Commission
EPA
The United States Environmental Protection Agency
Facility Closure
Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow
this permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 ml collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the CWA.
Instantaneous flow measurement
A measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total
discharge.

Dear Ms. Henson:
DAK Americas LLC recognizes the importance of proper sampling techniques and
procedures to insure quality data in protecting our waterways. The sampling deficiency
has been corrected by increasing the aliquot size to 100 ml and reducing the sampling
frequency to 20 minute intervals. Sampler has been programmed to insure that samples
will meet the frequency and volume criteria as stated in our NPDES Permit. Sampler will
be double checked before our next sampling event scheduled for February 2013. We
apologize for this oversight as we strive to maintain 100% compliance with our NPDES
Permit.
