Enclosed is the NPDES Form2A Application for Permit Number NC0020656, the City of Laurinburg's Leith
Creek WWTP. We are requesting a renewal for this permit.
The Authorized Representative for this facility is Mr. Charles Nichols, City Manager.
Sludge that is generated at this facility is land applied at Laurinburg-Maxton Airport in connection with Land
Application of Residuals Permit Number WQ0002526. Leith Creek WWTP has two aerobic digesters with
a total volume of 800,000 gallons. We try to perform four land application events per year for a total of 3.2
million gallons. However if we need to apply more we will lime stabilize to perform these events more
frequently.
We have completed one additional fathead minnow toxicity test in February 2014, along with our normal
toxicity test. Per Cindy Moore's request, three additional fat head tests are scheduled for March, April and
May 2014. We will forward the results as soon as we receive them.
If you have any questions concerning this renewal request please call me at the number below.
Sincerely,
Robert Ellis

SUPPLEMENTAL APPLICATION INFORMATION.
PART E TOXICITY TESTING DATA`
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are
required to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of_40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question E.4 for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E.
If no biomonitoring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to
complete.

Description of Collection System
The City of Laurinburg's collection system consists of 34 pump stations located
throughout the system. There are 123.7 miles of gravity sewers and 24 miles of force
mains. Our Leith Creek Plant consist of two types of treatment, one extended aeration
plant, consisting of 2 aeration basins, 2 clarifiers, 2 chlorine contact chambers and one
return sludge pump station with 3 pumps, total capacity 2.0 million gallons per day
(MGD).
The second plant is an oxidation ditch style with 1 clarifier, 1 chlorination point and 1
return sludge pump station with 3 dual speed pumps, total capacity 2.0 MGD, for a total
treatment capacity of 4.0 MGD. The facility has 2 aerobic digesters, (1) 150,000-gallon
tank and (1) 650,000-gallon tank with course air diffusers.

Qualifier Meaning
Attachment B
Explanation of QC Qualifier Codes
J4 The associated batch QC was outside the established quality control range
for accuracy.
T2 (ESC) - Additional method/sample information: The laboratory analysis was
from an unpreserved or improperly preserved sample.
Qualifier Report Information
ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and
as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted
by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical
results. Each qualifier is designated in the qualifier explanation as either EPA or ESC.
Data qualifiers are intended to provide the ESC client with more detailed information concerning
the potential bias of reported data. Because of the wide range of constituents and variety of
matrices incorporated by most EPA methods,it is common for some compounds to fall outside of
established ranges. These exceptions are evaluated and all reported data is valid and useable
"unless qualified as 'R' (Rejected)."
Definitions
Accuracy - The relationship of the observed value of.a known sample to the
true value of a known sample. Represented by percent recovery and
relevant to samples such as: control samples, matrix spike recoveries,
surrogate recoveries, etc.
Precision - The agreement between a set of samples or between duplicate samples.
Relates to how close together the results are and is represented by
Relative Percent Differrence.
Surrogate - Organic compounds that are similar in chemical composition, extraction,
and chromotography to analytes of interest. The surrogates are used to
determine the probable response of the group of analytes that are chem-
ically related to the surrogate compound. Surrogates are added to the
sample and carried through all stages of preparation and analyses.
TIC - Tentatively Identified Compound: Compounds detected in samples that are
not target compounds, internal standards, system monitoring compounds,
or surrogates.

Fisher's Exact Test
B = 12 a = 12
a/A = 1.00 b/B = 1.00
Success is: survival
Critical b value = 8
12 > 8
b = 12
The test concludes that the proportion of survival is not
significantly different for the control and the effluent groups.

W = X 167.9628
175.6667
Calculated W = 0.956 Critical W = 0.884
0.956 >_ 0.884
The reproduction data is normally distributed
evaluated at a 999s confidence interval.
Test Passes!
F test for Homogeneity of Variance
Control variance 8.8182
F - _ - 1.23
Effluent variance 7.1515
Numerator degrees of freedom: 11 Denominator degrees of freedom: 11
Critical F = 5.32
1.23 s 5.32 =o- The Test PASSES, the variances of the two groups
are significantly the same, homogeneous.

EQUAL VARIANCE t TEST
26.5 - 25.7
t = - 0.722
1.154
Degrees of freedom = 22
Critical t = 2.508
•
0.722 < 2.508
Test passed. There is not a significant difference in reproduction
between the Control and the effluent evaluated at a 999s confidence interval.
