1.0 INTRODUCTION
The North Carolina Division of Water Quality (DWQ) has identified a 10.1mile segment of
Clark Creek in the Catawba River Basin as impaired by fecal coliform bacteria, turbidity,
and copper (NCDWQ and WPCOG, 2001). The impaired segment due to fecal coliform
bacteria is located from 0.9 miles upstream of Walker Creek to the confluence with the
South Fork Catawba River. This section of the stream, located in sub-basin 030835, is
designated as a class WS-IV water.1
The 303(d) process requires that a Total Maximum Daily Load (TMDL) be developed for
each of the waters appearing on Part I of the 303(d) list. The objective of a TMDL is to
allocate allowable pollutant loads to known sources so that actions may be taken to restore
the water to its intended uses (USEPA, 1991). Generally, the primary components of a
TMDL, as identified by USEPA (1991, 2000a) and the Federal Advisory Committee
(FACA, 1998) are as follows:
Target identification or selection of pollutant(s) and end-point(s) for consideration. The
pollutant and end-point are generally associated with measurable water quality
related characteristics that indicate compliance with water quality standards. North
Carolina indicates known pollutants on the 303(d) list.
Source assessment. All sources that contribute to the impairment should be identified and
loads quantified, where sufficient data exist.
Assimilative capacity estimation or level of pollutant reduction needed to achieve water
quality goal. The level of pollution should be characterized for the water body,
highlighting how current conditions deviate from the target end-point. Generally,
this component is identified through water quality modeling.
Allocation of pollutant loads. Allocating pollutant control responsibility to the sources of
impairment. The waste load allocation portion of the TMDL accounts for the loads
associated with existing and future point sources. Similarly, the load allocation
portion of the TMDL accounts for the loads associated with existing and future non-
point sources, storm water, and natural background.
Margin of Safety. The margin of safety addresses uncertainties associated with pollutant
loads, modeling techniques, and data collection. Per EPA (2000a), the margin of
safety may be expressed explicitly as unallocated assimilative capacity or implicitly
due to conservative assumptions.
Seasonal variation. The TMDL should consider seasonal variation in the pollutant loads
and end-point. Variability can arise due to stream flows, temperatures, and
exceptional events (e.g., droughts, hurricanes).
1 Class WS-IV waters are freshwaters that are protected for water supply, secondary recreation, fishing, and
aquatic life, including propagation and survival of wildlife.
Clark Creek Fecal Coliform TMDL

Section 303(d) of the CWA and the Water Quality Planning and Management regulation
(USEPA, 2000a) require EPA to review all TMDLs for approval or disapproval. Once EPA
approves a TMDL, then the water body may be moved to Part III of the 303(d) list. Water
bodies remain on Part III of the list until compliance with water quality standards is
achieved. Where conditions are not appropriate for the development of a TMDL,
management strategies may be implemented in an effort to restoration of water quality.
The goal of the TMDL program is to restore designated uses to water bodies. Thus, the
implementation of bacteria controls will be necessary to restore uses in Clark Creek.
Although an implementation plan is not included as part of this TMDL, reduction strategies
are needed. The involvement of local governments and agencies will be critical in order to
develop implementation plans and reduction strategies. DWQ will begin contacting local
governments and agencies about implementation strategies during public review of this
TMDL.
1.1 Watershed Description.
Clark Creek flows from Catawba and Lincoln counties in the piedmont region of North
Carolina (Figure1A). It is a tributary to the South Fork Catawba River (Sub-basin 030835)
in the Catawba River Basin. Clark Creek joins the South Fork Catawba River near
Lincolnton, NC. The hydraulic length of Clark Creek is approximately 22 miles and the
creek has a drainage area of approximately 91 square miles. Land use in the watershed is
primarily forest (45%), pasture and recreational grass (19%), cultivated (17%), urban
development (17%), and other land uses such as wetland, pond, and barren (2%) (Figure 2).
The average flow of the creek near Lincolnton is approximately 109 cubic feet per second
(cfs), with a summer 7Q10 of 15 cfs (Giese and Mason, 1993). The Creek is less prone to
become dry during drought conditions (NCDWQ, 2002). The watershed includes drainage
from the municipalities of Hickory, Conover, Newton, Maiden, and Lincolnton. From the
source of Clark Creek to a point 0.9 miles upstream of Walker Creek, Clark Creek is

South Fork Catawba River, the stream is classified WS-IV.
1.2 Water Quality Target: North Carolina Water Quality Standard.
The North Carolina fresh water quality standard for Class WS-IV and C waters for fecal
coliform (T15A: 02B.0211) states:
Organisms of the coliform group: Fecal coliforms shall not exceed a geometric mean of
200/100mL (MF count) based upon at least five consecutive samples examined during
any 30-day period, nor exceed 400/100mL in more than 20 percent of the samples
examined during such period; violations of the fecal coliform standard are expected
during rainfall events and, in some cases, this violation is expected to be caused by
uncontrollable nonpoint source pollution; all coliform concentrations are to be
analyzed using the membrane filter technique unless high turbidity or other adverse
conditions necessitate the tube dilution method; in case of controversy over results, the
MPN 5-tube dilution technique will be used as the reference method.
The in-stream numeric target, or endpoint, is the restoration objective that is expected to be
reached by implementing the specified load reductions in the TMDL. The target allows for

the evaluation of progress towards the goal of reaching water quality standards for the
impaired stream by comparing the in-stream data to the target. In the Clark Creek
watershed, the water quality target is the 30-day geometric mean concentration of 200
colonies /100ml.
1.3 Water Quality Assessment.
The DWQ monitors a suite of water quality parameters, including fecal coliform bacteria, at
ambient stations throughout the state on a monthly basis. There is one DWQ ambient station
in this watershed located near the outlet of Clark Creek at Grove Street (SR 1008) near
Lincolnton (Figure 1A). Fecal coliform levels at SR1008 are responsible for the 303(d)
listing of a portion of Clark Creek.
Two of the three major NPDES permit holders in the Clark Creek watershed monitor
instream levels of fecal coliform bacteria, the Newton and Maiden WWTPs. Both permit
holders monitor instream fecal coliform weekly from October through May, and three times
per week from June through September. Instream monitoring occurs at the following three
locations: SR2014 (McKay Rd), SR2007 (West Maiden Rd), and SR1282 (Clarks Creek
Dr). The instream Discharge Monitoring Report (DMR) data were available from 1996
though 2001. The DMR data offers the unique opportunity to calculate a 30-day geometric
mean using 5 or more samples during that period. The 30-day geometric mean can be
calculated for most of the June through September period, and at irregular intervals during
the October through May period. In most of the periods, the 30-day geometric mean of the
fecal coliform concentration at the DMR locations remained considerably higher than 200
colonies / 100 ml. The 30-day geometric mean fecal coliform concentrations for 1996
through 2000 are shown in Appendix IA for each location.
While DMR data can be used to evaluate potential compliance with the standard and to aid
modeling studies, these data are not considered Level 1 data for use support and 303(d)
listing purposes. Level 1 data requirements are described in the 2000 North Carolina 303(d)
list. Generally, the bacterial levels at SR 1008 are typical of fecal coliform levels in many
Clark Creek Fecal Coliform TMDL
7
urban areas, with frequent concentration spikes. Out of 57 samples collected during the
study period (1996 through 2000), 33 were exceeding 400 colonies / 100 ml (57%).
In February 2001 DWQ staff met with representatives from Catawba County, the City of
Newton and the Town of Maiden. As a result of this meeting, a special study was conducted
to further the spatial extent of fecal coliform data in the watershed. The City of Newton and
the Town of Maiden each collected fecal coliform at two additional stations. Newton
collected additional data at Settlemyre Bridge (SR 1165) over Clark Creek and near the
mouth of Hildebran Creek. Maiden collected additional data downstream of SR 1279 over
Larkard Creek and near the mouth of Maiden Creek (Pinch Gut Creek). These data were
collected weekly for eight weeks beginning March 2001. A summary of these data is
presented in Appendix IB. During the sampling period (April 2001), there was little rainfall.
As a result, the concentration of the fecal coliform remained considerably lower than 200
colonies / 100 ml.
In April of 2001, DWQ staff conducted an additional study to determine compliance with
the fecal coliform standard. Weekly samples were collected for eight weeks at SR 1008,
Clark Creek at Grove Street in Lincolnton. A summary of these data is presented in
Appendix IB. These additional samples verified impairment, generating geometric means
greater than 200 cfu/100mL in all cases.
2.0 SOURCE ASSESSMENT
The source assessment characterizes the known and suspected sources of a pollutant to the
impaired water body. These sources will be represented within the water quality model for
the water body, whether explicitly or implicitly. Generally, sources of fecal coliform
bacteria may be point or non-point in nature. Point sources are typically those regulated
under the NPDES system, permitted discharges for which the DWQ has significant
information. NPDES facilities measure fecal coliform levels in the effluent at a frequency
based on facility class and waste type. Non-point sources are diffuse sources that typically
cannot be identified as entering a water body at a single location. These sources may
involve land activities that contribute fecal coliform bacteria to surface waters as a result of
Clark Creek Fecal Coliform TMDL
8
runoff producing storm events. The following sections describe point and non-point sources
of fecal coliform bacteria in the Clark Creek watershed.
2.1 Point Source Assessment.
There are currently nine NPDES permits within the Clark Creek watershed (Table 1).
However, two of these permitees, Fairgrove WWTP and Conover WWTP, did not discharge
effluent during the study period, 1996 through 2000. Of the seven remaining permitees, the
three facilities (Newton WWTP, Maiden WWTP, and Precedent, Inc.) that discharged
domestic wastes monitored fecal coliform in the Clark Creek watershed. The monthly fecal
coliform load from these facilities is presented in Appendix III.

2.2 Non-point Source Assessment
Fecal coliform bacteria non-point sources include those sources that cannot be identified as
entering the water body at a specific location. Non-point source pollution can include both
urban and agricultural sources, and human and non-human sources (Table 2). The non-point
sources of fecal coliform bacteria in Clark Creek include wildlife, livestock (land application
of agricultural manure and grazing), urban development (stormwater runoff, including
sources from domestic animals), failing septic systems, and sewer line systems (illicit
connections, leaky sewer lines and sewer system overflows).

2.2.1 Livestock.
Catawba and Lincoln counties are accounted as the major producers of livestock in North
Carolina. According to the 1999 livestock population census, there were about 17,000 and
15,000 livestock in the counties respectively (NCDA, 2001).
In order to incorporate the actual amount of fecal coliform deposit from these livestock, a
survey was conducted with the help of Catawba County Agent, Mr. Jeff Carpenter and
Catawba Valley Cattleman’s Association Member, Dr. Clarence Hood, to innumerate the
actual head count of livestock in the Clark Creek watershed. The estimated head count result
is presented in Table 3.
About 50% of these cattle were managed under the NC Agriculture Cost Share Program
since 1990 for about ten years (personal communication with the Catawba County District
Conservationist, Mr. Larry Williams). The program prohibits the grazing of the cattle near
the streams in the watersheds. (Picture of the cattle under the NC Agriculture Cost Share

program is presented in ApprndixVII). One of the objectives of the program is to control the
fecal coliform bacteria contamination due to direct contact between cattle and water.

Mature Beef Cows 600 100
Milk Cows 10 90
Horses* 246 61
* The number of horses in the watershed was estimated based on
the statistics presented in 1996 North Carolina Equine Survey.
However, during a field survey, DWQ staff noted one large herd of beef cattle in the Cline
Creek sub-watershed. Additionally, DWQ staff and local officials observed a dairy farm in
the Larkard Creek sub-watershed, where cows were seen in the creek. Many smaller herds
of cattle (i.e., 10-20 cows) were observed throughout the basin. One path utilized by animals
was noted during a stream walk by the Watershed Assessment and Restoration Program; this
path is located upstream of the SR2007 road crossing and provides direct access to Clark
Creek.
DWQ staff and local staff also noted considerable number of horse farms. (Picture is
presented in Appendix VII). Because of the limited time factor, a survey could not be
conducted to estimate the number of horses in the watershed. However, a best estimation
was performed using the statistics presented by North Carolina Equine Survey (1996). The
estimated head count of the horses is presented in Table 3. There were no hog, pig, and
chicken farms in the Clark Creek Watershed.
2.2.1.1 Livestock Grazing.
Cattle (dairy and beef cows) and horse graze on pastureland deposit feces onto the land.
During a rainfall runoff event, a portion of the fecal material that contains coliform bacteria
is transported to the streams. Open lots used heavily by animals have the greatest potential
for bacteria in runoff to surface water. In addition, when cattle have direct access to
streams, feces may be deposited directly into a stream.
Clark Creek Fecal Coliform TMDL

Once the bacteria reach a water body, environmental factors influence the extent of their
growth and decay. Physical factors such as photo-oxidation, adsorption, flocculation,
coagulation, sedimentation, and temperature will have a great influence on the bacteria
populations (USEPA, 1985). Some studies have suggested a significant positive correlation
among the bacteria, stream flow, and stream temperature along with a negative correlation
with pH, specific conductance, and disolved oxygen (Wilhelm and Maluk, 1998; and Clark
and Norris, 1999).
2.2.1.2 Agricultural Manure Application.
Processed agricultural manure from confined dairy cattle operation is generally collected in
lagoons and applied on land surfaces (USEPA, 2000b). Approximately 75 percent of dairy
cattle manure was applied to cropland, and 25 percent was applied to pasture land in the
Clark Creek watershed located in Catawba County (Best estimation from a Catawba County
Agent, Mr. Jeff Carpenter). Similarly, about 50 percent of dairy cattle manure was applied
to cropland and pastureland in the watershed located in Lincoln County. The cattle manure
was applied during March and April. The application was also continued during September
and October in the croplands.
Fecal coliform loading rates for livestock in the Clark Creek watershed were estimated to be
1.06 x 1011 colonies/day/beef cow, 1.04 x 1011 colonies/day/dairy cow, and 4.18 x 108
colonies/day/horse (NCSU, 1994). The total fecal coliform load due to manure application is
therefore estimated to be 2.2 x 109 colonies/ ha/ month and 6.6 x 109 colonies/ ha/ month for
the cropland and pastureland respectively in Catawba County. Similarly, the load is
estimated to be 2.0 x 1011 colonies/ ha/ month and 6.8 x 1010 colonies/ ha/ month for
cropland and pastureland respectively in Lincoln County.
Beef cows and horses are assumed to be grazed in the pastureland throughout the year in the
both counties. Because of the pasture management practices under the NC Agricultural Cost
Share program, it is assumed that the total fecal coliform load was reduced by one third in
the watershed. This assumption was however validated while calibrating the water quality
Clark Creek Fecal Coliform TMDL
12
model with the observed fecal coliform bacteria concentration in the watershed. With this
assumption, the total fecal coliform load due to grazing beef cows were estimated to be 1.6 x
1011 colonies/ ha/ month and 9.3 x 1010 colonies/ ha/ month in Catawba County and Lincoln
County respectively. The respective loads due to grazing horses are estimated to be 9.0 x 108
colonies/ ha/ month and 2.3 x 108 colonies/ ha/ month.
2.2.2. Failed Septic Systems.
Failing septic systems have been cited as a potential source of fecal coliform bacteria to
water bodies (DEH, 2000). More than half of the residents in Catawba County and Lincoln
County utilized septic systems (Table 4).
Table 4. Summary of Septic Usage in Catawba and Lincoln Counties (DEH 1999)
Percent of Housing Units Utilizing:
County 1999 Population Sewer Septic Other
Catawba 118,412 44.13 54.90 1
Lincoln 50,319 17.75 80.60 2
In the Clark Creek watershed, the number of septic systems per square mile is greatest in the
area surrounding Hickory and Newton. About 2,800 septic systems were estimated in the
watershed region. A GIS map developed by Catawba County, NC, showing the spatial
distribution of the houses with septic systems was utilized to estimate the number of septic
systems. It was also estimated that there were about 3 people per household per septic
systems. Septic system failure rate data in the counties are very limited. A study conducted
in 1981 by the North Carolina Office of State Budget and Management suggested that
approximately 11% of systems that were surveyed experienced malfunctions or failures over
a year in North Carolina State (DEH, 2000).
The water quality model, WARMF, uses three types of septic to estimate fecal coliform
discharge rates. These types represent varying performances and effluent quality such as
standard systems, advance treatment systems, and or failing systems. Due to lack of site
specific data Standard septic systems were used for this study.
Clark Creek Fecal Coliform TMDL

2.2.3 Urban Development/Sanitary Sewer Overflows/WWTP Residual Land Application.
Fecal coliform bacteria can originate from various urban sources. These sources include pet
waste, runoff through stormwater, sewers, illicit discharges/connections of sanitary waste,
leaky sewer systems, and sewer systems overflows (Table 2). The City of Newton owns and
operates the Newton Clark Creek WWTP and the sewage collection system. The pipelines
connecting between the WWTPs and the sewages in the Clark Creek watershed run along
the main Clark Creek. (Picture is presented in Appendix VII). Therefore, failure of
connection between the sewer pipelines or any leak from the pipe could result in profound
fecal coliform contamination in the creek.
Due to lack of data on the site specific fecal coliform loading from the urban development in
the Clark Creek watershed, the estimation of fecal coliform loading from the nearby county,
Mecklenburg County, was utilized for this study. As per the estimation (NCDWQ, 2002),
the respective fecal coliform load from light residential land use, Heavy residential land use,
and heavy industrial/commercial are 5.08 x 1011 colonies/ha/month, 6.7 x 1011
colonies/ha/month, and 2.0 x 1011 colonies/ha/month. These estimated values were
respectively input in the model to estimate total fecal coliform load from low intensity
development, commercial/industrial development and high intensity development. These
values were, however, adjusted during the model calibration to imitate the estimated fecal
coliform load with the observed load.
2.2.4 Wildlife (Background Source).
Wildlife deposit fecal material in forested, wetland, pasture and cropland areas which can be
transported to a stream in a storm event. Deposition of fecal coliform due to wildlife
population is natural and uncontrollable. Therefore, wildlife is considered as a background
source of fecal coliform bacteria for this study.
Wildlife in the Clark Creek watershed includes deer, raccoons, squirrels, birds, and
waterfowl. As population estimates of raccoons, squirrels, birds, waterfowl and other
animals are not readily available, the wildlife fecal coliform contribution was accounted for
in the deer population. The deer population was estimated to be 20 to 30 animals per square
Clark Creek Fecal Coliform TMDL
14
mile in the watershed (Best professional judgement from a wildlife expert for the region,
Mr. Evin Stanford). The upper limit of 30 deer per square mile was chosen to account for
deer and other wildlife in the watershed. The fecal coliform loading rate assigned to deer
was estimated using 5.0 x 10 8 colonies/animal/day (USEPA, 2002). The total fecal coliform
load due to the wild animals was then estimated to be 1.8 x 109 colonies/ ha/ month in the
both counties.
3.0. MODELING APPROACH
3.1 Modeling Framework.
The watershed model named Watershed Analysis Risk Management Framework (WARMF)
was selected for fecal coliform TMDL evaluation for the Clark Creek watershed. The
watershed model is designed to support the USEPA’s protocol for estimating TMDL
calculation, allocation, and implementation. The model integrates all water quality equations
and database in a window based graphical user interface (GUI). The model runs basically
under four different modules, they are:
1. The Engineering module. The module simulates the hydrology and water quality for the
landscape of a river basin. The simulated parameters include flow, water depth, and
constituent concentrations.
2. The TMDL module. The module estimates TMDLs for non-point source loads (LA)
under different control levels of point source loads (WLA) and vise versa. During
TMDL estimation, the model considers conditions of all seasons as required by USEPA
guidelines for TMDL calculation. In the case of fecal coliform bacteria TMDL, the
model simulates the deposition and transportation of the bacteria from land surface
discharge and point source discharge. The model then compute the resulting water
quality response using the first order kinetic equation 1 as follows:
dC/dt = θ (T- 20) KC ---------------------------------------------(1)
Where C is concentration of fecal coliform bacteria in count per100 ml (# / 100 ml); K is
decay rate per day; θ is temperature adjustment coefficient; and T is temperature of
water in centigrade.
The model then generates the percent reduction of the fecal coliform as required by the
EPA guideline for TMDL calculation. The model calculates the TMDL from the most
upstream water quality limit sections to the most downstream water quality limit
sections of the Clark Creek watershed.
Clark Creek Fecal Coliform TMDL

3. The Consensus module. The module follows the guidelines of the watershed approach
issued by the USEPA.
4. The Data module. The module facilitates the model to simulate dynamics of river basin
using meteorology, air quality, precipitation quality, point source discharge, and
reservoir flow release data. Hydrology and water quality data are used to check against
the module results. The data module stores data sets in ASCII text files, one file per
monitoring station.
The WARMF model works on watersheds that include catchments, river segments, and
stratified lakes. The model has been applied to different watershed regions in the USA and
Taiwan (Systech Engineering, 2001).
3.2 Model Setup.
The Clark Creek watershed was delineated using the Reach file 3 (Rf3) stream coverage and
Digital Elevation Model (DEM) data. The total drainage area of the watershed was
estimated to be 91 square miles with drainage density of 0.55 per mile. The headwaters of
the watershed were within the City of Hickory at an elevation of about 1100 feet above the
mean sea level and were dominated by industrial and commercial development areas. The
elevation dropped down to 340 feet at the outlet of the watershed. The lower drainage was
dominated by cropland, pasture land, and forested land. The land coverage types were
presented in Figure 2. WARMF represents the watersheds as a series of smaller
catchements. A total of 20 catchements were simulated for the Clark Creek watershed.
The water quality data collected at the ambient monitoring stations, SR1008, and the
Newton WWTP instream monitoring at SR2007 were utilized to calibrate the model. The
SR2007 was located at the middle portion of the watershed near upstream of west Maiden
Road (Figure 1A). The SR1008 was located near the outlet of the watershed at Grove Street
in Lincolnton.
The meteorological data collected by the nearby weather stations located at Hickory and
Lincolnton were also utilized to calibrate the model. The weather station in Hickory was
Clark Creek Fecal Coliform TMDL
16
assigned for the upper portion of the Clark Creek watershed, above SR2007. The weather
station in Lincolnton was assigned to the lower portion of the watershed.
3.3 Model Calibration.
The variables were classified into two categories – controllable and uncontrollable variables.
The controllable variables include: the estimates of non-point source loads (e.g.
urbanization, fertilizer application, etc), point source load (e.g. flow and pollutant
concentrations), and rate coefficients (e.g. infiltration rate, precipitation weighting factor,
average temperature lapse, fecal coliform decay rate, etc). The in situ values for these
variables were not available and hence the risk associated with the estimated values of these
variables could be high. In order to minimize the risk, statistical testing was performed. The
variation between the measured and estimated fecal coliform concentrations was evaluated
by estimating the coefficient of determination (R-Squared). A high value of R-Squared
value suggests less variation between the measured and estimated fecal coliform
concentrations.
The uncontrollable variables include watershed characteristics (e.g. land classes, stream
morphology etc) and meteorology (rainfall, temperature etc). These variables, on the other
hand, are inherent with the environmental system. Hence, these variables were kept constant
in the model simulation.
3.3.1 Hydrology.
Two hydrologic parameters - water flow and water temperature were chosen to calibrate the
watershed model. Calibration of the model with regards to flow is essential, because the
flow is the main carrier of fecal coliform bacteria from field to stream. Similarly the
calibration with regards to water temperature is important, because the temperature
determines the die-off rate of fecal coliform bacteria (Equation 1). As the temperature
increases, the fecal coliform concentration also increases (Clark and Norris, 1999).
However, the calibration of the model with regards to flow during the study period could not
be performed for the Clark Creek watershed. Only a few flow measurements were
Clark Creek Fecal Coliform TMDL
17
monitored during 1996 in the ambient gage station, SR1008. Flow monitoring did not occur
at SR2007 during the study period. Therefore, the hydrologic calibration of the model was
performed using flow data collected at the nearby USGS gage station, Indian Creek
watershed near Laboratory. This station is 3.72 miles away from SR1008 (Figure 1B).
In the calibration process, the precipitation weighting factors for the Hickory and Lincoln
weather stations were set to 1.0 and 1.05 respectively to obtain the close relationship
between the simulated and observed flow values. The time series of the simulated flow
values and the observed values were presented in Figure 3A. The correlation between the
two flows was slightly weak (R-Square = 0.59) due to spatial variability in precipitation.
However, the result suggests that the model considerably predicted the observed flow for the
Indian Creek Watershed.
Using the precipitation weighing factors determined for the Indian Creek watershed, the
hydrologic model was ground-truthed for the Clark Creek watershed using the 1996 flow
data measured at the SR1008. The model simulated the flow values closely with the
observed values (Figure 3B). However, due to the few data points, the model resulted in a
relatively low R-Square value.
The calibration of the model with water temperature was performed using the measured
water temperature data at the both stations - SR2007 and SR1008. The parameter
coefficients for the average temperature lapse and altitude temperature lapse were set to 2.5
and 0.005 respectively for both weather stations. The model calibration scored a high R-
Square values (0.71 to 0.77), suggesting a good correlation between the observed and
predicted water temperature in the Clark Creek watershed (Figure 4).
3.2.2 Water quality.
The watershed model was calibrated with the fecal coliform observed in SR2007 and
SR1008. In the calibration process, the reaction coefficients to adjust the decay rates of the
fecal coliform bacteria in the field and in the stream were set to 0.01and 0.1 respectively.
The input parameters estimated in the § 2.2.3 for the urban development were also further
Clark Creek Fecal Coliform TMDL
18
adjusted to correlate the estimated fecal coliform concentration with the observed
concentration. An acceptable relationship between the simulated fecal coliform bacterial
concentration and observed bacterial concentration was observed when the estimated
parameters were multiplied by 0.17 and 0.33 for the winter and summer periods respectively
(Figure 5).
The relationship was further examined by estimating 30-day geometric mean (Figure 6).
The relationship was somewhat weak for the first two years, 1996 and 1997. However the
relationship was significantly improved in the following years, 1998 through 2000. The
respective r (Pearson correlation) values estimated for the years were 0.04, -0.38, 0.60, 0.51,
and 0.12.
3.4 Model Uncertainty
Above week agreement between modeled and observed fecal coliform concentrations could
be due in part to the high degree of uncertainty associated with predicting fecal coliform
bacteria. The inability to accurately predict specific observed fecal coliform concentrations
can be attributed to model error, lack of sufficient information in source assessment, gaps in
our scientific knowledge, natural variability in instream fecal coliform concentrations, field
and laboratory measurement error, and lack of current site specific model input parameters
including decay rate, flow, rainfall data, and landuse information. The watershed model,
WARMF, selected to guide initial decision making, is not adept at characterizing prediction
uncertainty. The model estimates daily average fecal coliform concentrations based on
landuse information. Because of lack of site specific information, professional guess and
literature values were used to calculate the fecal coliform loading from the various land uses.
Therefore, the model results should be interpreted in light of the model limitations and
prediction uncertainty.
3.5 Model Output
3.5.1 Existing Condition
The model outputs indicate that the primary source of fecal coliform bacteria contamination
in the Clark Creek watershed is the direct input from the non-point sources (Table 5). The

contamination due to the point sources was only 5% (14,600 x 106 colonies /day) as
compared to the non-point sources (278,645 x 106 colonies /day). Urban development,
animal grazing, and septic system were seen to be more responsible for the fecal coliform
contamination in the Clark Creek watershed. In urban areas, fecal coliform can be
contributed to the creek by dog, cat, raccoon, stormwater runoff, and human waste during
storm events. In a study conducted by Hyer et. al, 2001, the contamination due to the dog
waste accounted for nearly 10 percent in the creeks of Virginia. Similarly, human waste
accounted nearly 20 percent. The human waste included failing septic systems, leaking
sewer lines, cross-connected pipes, straight pipes, and sewer line overflow. In this study, the
bacterial contamination due to the failure of septic system alone accounted for about 15 %
(45,400 x 106 colonies /day). The contamination due to urban activities accounted for about
53% (157,030 x 106 colonies /day). The contamination due to animal grazing accounted for
about 22% (65,800 x 106 colonies /day). The similar accountability due to wildlife in forest,

and other sources (e.g., wetland, water pond, and barren land) were found to be relatively
low (≤1%).

3.5.2 Critical Period
Critical period is the period when the geometric mean of fecal coliform concentration
reaches peak exceeding the water quality standard, 200 colonies / 100 ml. The DMR data
and the ambient data both indicated that elevated fecal coliform concentration levels
occurred during summer - May through October in the Clark Creek watershed (Appendices
1A). Usually, the concentration level was elevated after each rainfall event (Appendixes
1C) during summer. Interestingly, just opposite was the result during winter. The
concentration level was reduced even after each rainfall event.
Clark Creek Fecal Coliform TMDL
24
The result suggests that the elevated concentration of the bacteria during summer could be
due to low flow in the Clark Creek. During the dry weather, the flow in the Clark Creek
remained low as compared to winter (November through April). As per the flow from the
nearest watershed, Indian Creek, the average flow during the summer ranged from 0.64
cubic meter per second in September to 2.1 cubic meter per second in May. In a contrast, the
flow raised comparatively high during the winter. The flow ranged from 1.1 cubic meter per
second in November to 4.28 cubic meter per second in January (Figure 7).
Figure 7. Monthly average flow from Indian Creek. The average flow was estimated using
the flow data from 1996 through 2000.
The watershed model, WARMF, was run for a five-year simulation period, 1996 through
2000, using estimated daily flows to examine the critical period. The predicted maximum
concentration level ranged from 635 colonies / 100 ml to 2,084 colonies / 100 ml during
winter weather conditions (Table 6). The range of the concentration level was relatively
high during summer weather conditions. The concentration level ranged from 2,062 colonies
/ 100 ml to 5,871 colonies / 100 ml. During the study period, the most critical period was

4.0. ALLOCATION
4.1. Total Maximum Daily Load.
Total Maximum Daily Load (TMDL) can be defined as the total amount of pollutant that
can be assimilated by the receiving water body while achieving water quality standards. A
TMDL can be expressed as the sum of all point source loads (WLAs), non-point source
loads (LAs), and an appropriate margin of safety (MOS), which takes into account any
uncertainty concerning the relationship between effluence limitations and water quality.
This definition can be expressed by equation 2:
TMDL = ∑WLAs + ∑LAs + MOS ---------------(2)
Clark Creek Fecal Coliform TMDL
26
The objective of the TMDL is to estimate allowable pollutant loads and to allocate to the
known pollutant source in the watershed so the appropriate control measures can be
implemented and the water quality standard can be achieved. The Code of Federal
Regulations (40 CFR § 130.2 (1)) states that TMDLs can be expressed in terms of mass per
time, toxicity, or other appropriate measures. For fecal coliform bacteria, TMDLs are
expressed as colonies per 30 days. Therefore, the TMDL represents the maximum fecal
coliform load that can be assimilated by the stream during the critical 30-day period while
maintaining the fecal coliform water quality standard of the geometric mean of 200 colonies
/100 ml over 30 days.
The TMDL module of the WARMF model, as describe in § 3.1 above, is utilized to estimate
the TMDL for fecal coliform based on stream flow and instream fecal coliform
concentrations that originated from different sources in the Clark Creek watershed. The
TMDL was determined by systematically reducing the watershed loads until all 30-day
geometrical mean concentration were below the TMDL target of 175 colonies / 100 ml. The
resulting reduction is presented in Figure 9 for the period from 1996 through 2000. The
existing average daily load of fecal coliform bacteria to SR1008 is 296,852 x 106 colonies /
day (Table 5). The TMDL load at the same location is 21,254 x 106 colonies / day. The
estimation of the TMDL is described in the following paragraphs.
4.2 . Seasonal Variation.
Seasonal variation was incorporated in the continuous simulation of the watershed model by
using varying monthly loading rates and daily meteorological data for 5 years, 1996 through
2000. The variation of the predicted and observed fecal coliform bacteria was
comparatively high during summer and low during winter, but the concentration level
remained greater than the water quality standard (200 colonies / 100 ml) during most of the
simulation periods (Figure 9).
4.3. Margin of Safety (MOS).
The MOS was explicitly included in the TMDL analysis by setting the TMDL target at 175
colonies / 100 ml, which is 25 colonies / 100 ml lower than the water quality target of 200
Clark Creek Fecal Coliform TMDL
27
colonies / 100 ml. Conceptually, the MOS was included in the TMDL estimation to account
for the uncertainty in the simulated relationship between the fecal coliform load and the
water quality standard.
The explicit MOS for this study is, therefore, set to 25 colonies / 100 ml. The daily MOS
load is estimated to be 7.0 x 109 colonies. The estimation was performed by calculating the
differences between TMDL with MOS and TMDL without MOS using the equation 2.

SR1008 Allocation Standard Margin of Safety
Figure 8. 30-day rolling geometric mean of the simulated fecal coliform concentration
before and after TMDL allocation at SR1008.
4.4. Waste Load Allocation.
The fecal coliform contamination in the Clark Creek watershed due to point sources was
only 5% of the total load (Table 5). The percentage of fecal coliform bacteria was attributed
to the three main NPDES sources, Newton WWTP, Maiden WWTP, and Precedent, Inc
Clark Creek Fecal Coliform TMDL
28
(Table 1 and Appendix 4). The remaining four sources, GE Hickory, Maiden WTP, Delta
Mills Inc, and National Fruit, did not discharge fecal coliform to the creek.
Newton WWTP, Maiden WWTP, and Precedent, Inc, are permitted to discharge a monthly
geometric mean fecal coliform concentration of 200 colonies / 100 ml with a maximum
permitted discharges of 5 MGD, 0.008 MGD, and 1 MGD respectively. The total permitted
load of fecal coliform bacteria is thus estimated to be 4.5 X 1010 colonies per day, which is
indeed substantially higher than the actual discharge load, 1.5 X 1010 colonies per day (Table
5). Therefore, a waste load allocation (WLA) reduction was not recommended for the
watershed.
4.5. Load Allocation (Non-point Source).
Based on the existing condition of the watershed ( 3.3.1), the focus of reductions should be
non-point sources. The load allocation (LA) for the non-point sources (NPS) was estimated
by multiplying the 30-day geometric mean simulated by the model after reduction (Figure 8)
by the respective flow values. The estimation was done for the period when the maximum
30-day geometric mean was simulated. The estimation suggests that the total maximum LA
for the non- point sources be 6.5 x 1010 colonies per day. In average, the total reduction
required to meeting the water quality standard, 175 colonies per 100 ml is thus estimated to
be 77%.
The total LA was then proportionally distributed to each of the non-point sources. The LA
distribution was mainly targeted to urban developed area, septic system, animal grazing,
because these sources contributed substantial fecal coliform bacteria to the Clark Creek (
3.3.1). Fecal coliform bacteria from urban developed area can originate from various
sources including leaking sanitary sewers, illicit sanitary sewer connection, and storm water
runoff. The storm water runoff can include waste from domestic animals and urban wildlife.
The model results suggest that a substantial amount of fecal coliform bacteria were
transported to the Clark Creek from Newton and Maiden cities. The estimated proportional
reductions required in the various sources to meeting the water quality standard, 175
colonies per 100ml, in the Clark Creek watershed are presented in Table 7.

5.0 SUMMARY AND FUTURE CONSIDERATIONS
The sources of fecal coliform bacteria in the Clark Creek watershed include primarily urban
development, animal grazing, and septic system. These sources accounted about 53%, 22%,
and 15% respectively. In order for the water quality target to be met, the final allocation of
the fecal coliform bacteria requires a non-point source load reduction 6.5 X 1010 colonies per
day for the various non-point sources of the fecal coliform bacteria.
The pipelines connecting between the Newton Clark Creek WWTP and the sewage
collection system in the watershed run along the main Clark Creek. The city of Newton is
therefore suggested to check any leak from the connecting pipe. Failure of connection
between the sewer pipelines or any leak from the pipe could result in profound fecal
coliform contamination in the creek.
The model estimated that the point sources contributed about 5% of the total loading in the
watershed. The waste load allocation, as of DWQ permission, was estimated to be 4.5 x
1010 colonies per day. The permitted load was appeared to be considerably lower than the
actual discharged load, 1.5 x 1010 colonies per day. Therefore, reduction is not
recommended for fecal coliform loading from point sources.
5.1 Monitoring
Fecal coliform monitoring will continue on a monthly interval at the existing ambient
monitoring site. The continued monitoring of fecal coliform concentrations will allow for
the evaluation of progress towards the goal of reaching water quality standards by
comparing the instream data to the TMDL target. In addition, flow monitoring will be
considered at SR1008. This additional flow monitoring will help to refine the TMDL in the
future.

To comply with EPA guidance, North Carolina may adopt new bacteria standards utilizing
Escherichia coli (E. coli) and enterococci in the near future. Thus, in future, monitoring
efforts to measure compliance with this TMDL should include using the E. coli and
enterococci. Per EPA recommendations (EPA, 2000b), if future monitoring for E.
coli/enterococci indicates the standard has not been exceeded, these monitoring data may be
used to support delisting the water body from the 303(d) list. If a continuing problem is
identified using E. coli/enterococci, the TMDL may be revised.

5.2 Implementation
Implementation plans are not included in this TMDL. The involvement of local
governments and agencies will be needed in order to develop implementation plans. The
DWQ will begin developing the implementation plan during public review of the TMDL.
6.0 PUBLIC PARTICIPATION
Many local government officials have been notified of DWQ’s intention to develop the
Clark Creek fecal coliform TMDL. The extension services in Catawba and Lincoln
Counties and local associations have supplied septic data, sewer data, and agricultural
information to aid in the source assessment portion of the TMDL. The Clark Creek Fecal
Colifom TMDL was public noticed in both counties through local newspapers (Hickory
Daily Record and Lincoln Time-News) on June 10, 2002 (Appendix V). The TMDL was
also public noticed through DWQ web site at http://h20.enr.state.nc.us/tmdl/.
A public meeting was held in Newton, NC, on July 1, 2002 as a part of the comment period.
A group of seventeen (17) individuals participated the meeting from the following
organizations:
1. Carolina Land and Lakes RC&D – 1 representative
2. Catawba County – 3 representatives
3. Catawba SWCD – 1 representative
4. Catawba Valley Cattleman’s Association – 2 representatives
5. City of Newton – 2 representatives
6. Department of Environmental and Natural Resources, MRO – 1 representative
7. Natural Fruit Production CO. – 1 representative
8. NC Division of Water Quality – 4 representatives
9. Sherrill Furniture – 1 representative
10. Western Piedmont COG – 1 representative
A public comment period was through July 10, 2002. Four written comments were received
through email and are included in Appendix V1. Each comment was carefully considered
and the TMDL was revised accordingly.

APPENDIX VI. Public comments on Clark Creek TMDL and DWQ responses.
A. Comments from Ms. Anne Coan, NC Farm Bureau Federation:
July 10, 2002
Mr. Narayan Rajbhandari
Water Quality Planning Branch
NC Division of Water Quality
1617 Mail Service Center
Raleigh, NC 27699-1617
Dear Mr. Rajbhandari:
The North Carolina Farm Bureau Federation is the state’s largest general farm organization
representing the interests of farm and rural people in our state. This letter is to comment on
the Clark Creek (in Subbasin 03-08-35) Fecal Coliform Total Maximum Daily Load
(TMDL.)
We feel that the methodology used to estimate the sources and to allocate the reductions is
highly flawed. Therefore, we oppose this TMDL document.
On Page 10 of the TMDL it is stated that there is one dairy and some beef cattle in the
watershed. However the paragraph goes on to discuss land application of poultry waste. It
is our understanding that there is no poultry waste applied to land in this watershed. Also,
there is a reference to the colonies per day of hog waste, but it is our understanding that
there are no hog operations and there is no hog waste applied in this watershed. Because
the only reference given is to confirm the presence of dairy and beef cattle in this watershed,
we assume that DWQ could not confirm the presence of poultry and hogs in this watershed
either, or a reference would have been cited. Therefore, the presence of poultry waste
and/or hog waste in the watershed must be confirmed if they are used to calculate sources
and source reductions. If these sources are not in the watershed, any references to these
should be removed, and any source calculations and reduction allocations using them must
be eliminated from the TMDL.
Also on page 10 there are fecal coliform loading rates given for livestock in the watershed.
It is obvious to us that the author is misusing the terminology for “loading” here. The
NCSU reference gives the data for fecal coliform totally excreted from the animal into an
animal waste treatment system or confinement area, prior to any treatment, exposure to
sunlight, etc. Using these numbers as “loadings” is comparable to figuring all of the fecal
coliform that arrives at all of the waste treatment plants in the watershed, prior to any
treatment, as the “loading” for these plants. It would be comparable to figuring the septic
Clark Creek Fecal Coliform TMDL
126
tank loadings by using all of the fecal coliform delivered from the buildings into every septic
tank in the watershed as the “loading” for septic tanks. Using the numbers on page 10 for
livestock as “loadings” absolutely cannot be justified.
Mr. Narayan Rajbhandari
July 10, 2002
Page 2
On page 11 of the document, there is a reference to 11 percent of the septic systems failing.
Therefore, it is assumed that 89 percent are working properly. Again, if animal waste
loadings are to be determined based on what is delivered to all of the treatment systems or to
all of the pastures, then septic waste fecal coliform levels should be figured based on what is
delivered from the homes or businesses to all of the septic tanks in the watershed, prior to
any treatment by the septic system. Also, using the methodology used to estimate livestock
fecals, all septic fecals should be considered as “loadings,” without any adjustment for 89
percent of septic systems functioning properly.
Regarding wildlife estimates, it is nonsensical to use the deer population to represent all of
the fecal coliform producing wildlife in this watershed. Further, this section states that
“Wildlife deposit fecal material in these areas which can be transported to a stream in a
storm event.” Then the document assigns a “loading rate” to deer. Because there is no
reference given, we cannot determine if this is what is delivered to the landscape or to the
stream. If the estimated loads of livestock waste on page 10 are used, then fecal estimates
delivered to the landscape by deer and all other wildlife must be used as well. As written,
this document substantially underestimates the wildlife fecal contribution.
The same comment regarding equitable estimates of loading applies to all of the sources,
both point and nonpoint, discussed in this document.
On page 20, the statement is made that the model indicates nonpoint sources as the primary
sources of fecal coliform. While the waste from sewer overflows, leaking sewer lines, and
cross-connected pipes is counted in the nonpoint source load, the point sources should be
held responsible for these sources, because they are attached to their systems. Therefore, the
nine point sources in the watershed should be assigned load reductions specifically for these,
because they are causing these nonpoint source problems. Assigning these types of load
reductions to “urban development” dilutes the responsibility for these problems by adding
them to runoff fecals generated by pet waste, urban wildlife, and other urban sources. Clear
responsibility should be assigned to these point sources for the nonpoint source loads they
are generating through reduction targets being specifically established for sewer overflows,
leaking sewer lines, cross-connected pipes and any other contamination caused by failure of
delivery systems to point sources.
Further, we feel it is important to point out that the point source loads are based on what is
reported by the point sources themselves, and they select the time the sample is taken. Such
timing can be adjusted to the most favorable conditions of weather and plant operation and,
therefore, may or may not be skewed towards the lowest measured fecal concentrations.

DWQ should substantiate these numbers over all weather conditions and during times of
optimum and less-than-optimum plant operation conditions.
Mr. Narayan Rajbhandari
July 10, 2002
Page 3
We oppose the reductions assigned to agriculture on page 28 of this document, based on the
comments above. We do not see how these 93 and 94 percent reductions from agriculture
can possibly be rationalized.
The statement is made that the implementation plan development will begin during the
public review of the TMDL. We were informed by a local citizen of this draft TMDL after
the public meeting, and few people were aware of the meeting or of this draft TMDL. Farm
Bureau should be informed of all TMDL development in North Carolina, and we hereby
request that we be informed. As the state’s largest farm organization, we represent
substantial numbers of stakeholders in all of these watersheds and should be kept informed
of the development of TMDLs. Further, we could have contacted affected farmers in the
watershed and let them know about the TMDL and the meeting, thereby increasing the
public participation. We are disappointed that we were not informed of this meeting, or of
the draft TMDL until very late in the process, and not by DWQ.
In summary, we feel this draft TMDL lacks the necessary scientific basis to go forward, and
request its withdrawal and reworking.
Thank you for the opportunity to comment on this draft TMDL. If you have any questions,
please contact me at (919) 788-1005.
Sincerely,
Anne Coan

Responses to the comments from Ms. Anne Coan, NC Farm Bureau Federation:
1. DWQ greatly appreciates your comments on the Fecal Coliform Bacteria TMDL for
Clark Creek. The following clarifications are made in regards to your comment:
2. The final TMDL report does not consider the poultry or hog waste loads
3. The terminology “Load” used to address total fecal coliform from the cattle seems
appropriate. The water quality model is required to input monthly loading rate of the
fecal coliform from the livestock without considering its decay rate. The model
estimates the actual amount of fecal coliform that could be delivered overland to the
stream considering the overland decay rates. The model uses a first order kinetic rate
equation to account for the strong temperature influence on the fecal coliform
bacteria die-off rate as stated in the report.
4. Eleven percent of the septic system failing addresses the State of North Carolina.
5. Except for deer, a wildlife inventory in the Clark Creek watershed is not readily
available. So, the upper limit of the deer population is used to estimate the fecal
coliform load from the wild animals in the watershed. This is an acceptable way of
estimation.
6. DWQ periodically monitors the waste loads from the nine WWTP and has not
noticed exceeded flow of fecal coliform from the WWTP during the study period.
Also, because the model requires inputs regarding sewer system and WWTP
separately, the model allocates load reduction to the point sources and non-point
sources separately. The model does not care whether the two sources are attached to
one pipeline in the watershed.
7. Public notice for the Clark Creek Fecal Coliform TMDL development was processed
through a standard procedure. The notice was posted in the DWQ web site
(http://h2o.enr.state.nc.us/tmdl) a month prior to the public meeting date, July 1,
2002. The notice was also announced through local newspapers, Hickory Daily
Record and Lincoln Time-News on June 10, 2002.

B. Comments from Dr. Clarence Hood, Catawba Cattlemen’s Association:
Dear Raj: Thanks for your E-mail and for discussing your report with me yesterday
afternoon. I will make a few comments on the report as we discussed yesterday:
1) I believe that your Fecal Coliform study should be integrated with the report of Tom
Yocum and others on the Biological Impairment in the Upper Clark Creek Watershed. There
seems to me to be some conflicting issues; and by combining these to present to local
governments would be a better approach and reduce confusion about what local agencies
need to do to address the problems in Clark Creek.
2) I believe that the impact of cattle on Clark Creek could be better presented by giving an
accurate inventory of cattle and pastureland in the watershed; I believe there are 1000 to
1200 head of cattle in the watershed and no swine or chickens or chicken litter applied to
pasturelands.
3) The number of horses in the area is considerable and they strip most all vegetation and
thus considerable manure etc reach streams.
4) On page 10 of the report the 1.06 x e11 colonies/day/beef cow; is the amount produced
but only a very small portion reaches the streams; Sunlight and other factors such as rainfall
should be considered; Does the model account for this?
5) Almost 60 % of flow in Clark Creek below Newton Waste Water Treatment Plant; is
contributed by the plant; Also considerable irrigation water is removed below this point for
turf applications; Is this accounted for in your; model?
6) On page 13 the 1100 ft elevation for Hickory dropping down to 800 ft at Lincolnton seem
to be error; That would be a 300 ft drop.
7) On page 20 the sentence ...manure application in pastureland... may be misleading and
using the words...livestock grazing...should be sufficient since it is understood that no
poultry litter or manure from confined cattle is being applied in the watershed. I hope these
comments will be helpful;
Please contact me if I can clarify. Clarence Hood.

Response to comments from Dr. Clarence Hood, Cattleman Association:
DWQ greatly appreciates your comments on the Fecal Coliform Bacteria TMDL for Clark
Creek. The following clarifications are made in regards to your comment:
1. We look forward to integrating the TMDL with the Biological Impairment in the Upper
Clark Creek Watershed to develop an implementation plan to reduce the fecal coliform
concentration in the entire Clark Creek watershed.
2. The NCDA report (2000) was used to best estimate the cattle population for the Clark
Creek watershed. However, DWQ appreciates your help together with Mr. Jeff
Carpentor, Area Livestock Agent and Mr. Carl Rector for providing the actual cattle
inventory in the watershed. The final TMDL report has included the inventory results.
3. The water quality model has considered the horse population. The 1996 Equine Survey
Statistics reported by NC Department of Agriculture and Consumer Services was
utilized to best estimate the population in the watershed.
4. The water quality model considers the fecal coliform decay factors. It utilizes a first
order kinetic rate equation to account for the strong temperature influence on the fecal
coliform bacteria die-off rate.
5. The water quality model considers the flow from the WWTP. The precipitation
weighting factor is well adjusted while calibrating the model to account the localized
water uses.
6. We appreciate your correction on the estimation of the elevation and the manure
application. The corrections have been considered in the final report. The actual change
in elevation is 340 ft at the outlet of the watershed. The model has not considered any
manure applications other than dairy cattle manure in the watershed.

C. Comments from Mr. Jeff Carpenter, Area Livestock Agent, Newton, NC.
Raj:
I enjoyed speaking with you on the phone on Wednesday concerning the
report that has been prepared for the Clark Creek watershed in Catawba and
Lincoln Counties. It seems as there has been quite a bit of monitoring and
data gathering to support the need for work in this basin. However, I have
several questions/concerns about the model that I hope you can answer.
Page 8 - one of the non-point sources you mention is concentrated
animal feedlots. There are no concentrated feedlots in this basin. In the
3 counties I serve there is only one operation that fits this description
and it is not in the Clarks Creek basin.
On page 9 you mention that open lots used by animals have the
greatest potential for bacterial runoff to surface water. I am not aware of
any such heavy use areas in this watershed as our beef operations are
predominantly pasture based with grazing activities accounting for about
9-10 months worth of feed for these animals. I suppose the one dairy you
mention in your report has such an area for the milking herd, but that
particular operation is small enough to not be impacted by .0200
regulations.
On page 10 your data appears to come straight from the Census of
Agriculture, which is the most reliable source for livestock numbers. I am
not sure how you interpreted the number of cattle, which is 17,000 for
Catawba and 15,000 for Lincoln County. This number reflects the number of
all cattle of all sizes and uses for both counties. The next number gives
the total number of mature beef cows, which is a more useful in calculating
total fecal coliform production/loading. A safe estimate for all cattle
numbers would be to assume 85% of these cows produce a calf each year and it
is usually marketed at an average of 525 lbs. I believe an accurate
estimation of the amount of fecal coliform produced by these animals should
take into account their smaller size and body weight, and the limited time
these calves are present on the farm each year. I am not sure if your model
assigns the same FC production to all 32,000 head or not.
Also on page 10, you report a fecal coliform loading rate of 1.06 x
10 (11) colonies/day/beef cow. The American Society of Agricultural
Engineers and the reference you cite for this figure (NCSU, 1994) both
report that this is TOTAL fecal coliform production per cow per day. I
believe to assume that all of this material reaches surface waters is very
inaccurate and I encourage you to give some credit for bacterial death due
to drying, exposure to sunlight, application on land by grazing animals, ...
I am also aware of several operations within this watershed that are

participating in the NC Ag Cost Share Program and have excluded their
livestock from all streams on their property, thereby limiting the amount of
FC loading in these waters. For accuracy I would encourage you to include
this in your model.
As I mentioned in our phone conversation, there are no poultry
operations that I am aware of within the Clarks Creek watershed and I do not
know of farmers within this area that are applying poultry litter to lands.
I would encourage you to revisit your model and make these revisions also
for accuracy.
On page 17 there is a discussion of the accuracy of the model in
estimating fecal coliform in the stream, but no accuracy values are
presented in figure 5. Is this information available?
I cannot determine from the report how many head of livestock are
estimated within the watershed, but I would be very happy to assist your
department in obtaining a very accurate count. The number of livestock
farms north of West Maiden Road are very limited and I think that within a
few days a very accurate estimate of these animals can be obtained. The
same could be done for the Lincoln County portion of the watershed.
If I can be of any assistance please do not hesitate to call on me.
If reductions in fecal coliform loading are needed by the livestock industry
I would be happy to assist your agency in working with landowners in this
effort.
Sincerely,
Jeff Carpenter
Area Livestock Agent
Responses to Mr. Jeff Carpenter, Area Livestock Agent, Newton, NC.
DWQ greatly appreciates your comments on the Fecal Coliform Bacteria TMDL for Clark
Creek. The following clarifications are made in regards to your comment:
1. The final TMDL does not include the concentrated feedlots and poultry operations in
the Clark Creek Watershed.
2. The fecal coliform load from the livestock operation is included in the model as per
the estimated census data provided by you.

3. The water quality model has considered the decay rate of the fecal coliform bacteria
in land and in streams. The reaction rates for the decomposition of the fecal coliform
in land and in streams are set at 0.01 per day and 0.1 per day respectively. A better
prediction of fecal coliform is obtained by using the reaction rates in this study.
E. Comments from Ms. Mary Geoge:
Thank you for your presentation on the results of DWQ’s fecal coliform study
on Clark Creek. In addition to the comments/questions at the July 1,
meeting I would like to reiterate that additional monitoring stations should
be put in place to better identify the sources of non-point source
pollution. Based on our discussions, it appears that there could be a large
contributor on the lower end of the watershed who may be influencing the
fecal coliform bacteria count. Before we work on implementation strategies,
I think it would be in everyone’s best interest to be certain of the
contribution each source makes to more effectively prepare an implementation
plan.
Should you have any questions regarding this matter, please feel free to
contact me.

Response to comments from Ms. Mary Geoge:
DWQ greatly appreciates your comments on the Fecal Cloriform Bacteria TMDL for Clark
Creek. We look forward to working with Catawba County Planning & Community
Development to develop implementation plan to reduce the fecal coliform concentration in
the Clark Creek watershed. We agree with regards to your comment on addition of
monitoring stations to measure flow rates in the watershed to better identify the sources of
non-point source pollution.
