Northeast Creek Fecal Coliform TMDL
1.0 INTRODUCTION
The North Carolina Division of Water Quality (DWQ) has identified an 8.4 mile segment of
Northeast Creek in the Cape Fear River Basin as impaired by fecal coliform bacteria
(NCDENR 2003). The impaired segments due to fecal coliform bacteria are located from 2.6
miles upstream of N.C. Hwy 55 to Durham County WWTP and 5.8 miles from Durham
County WWTP to a point 0.5 mile downstream of Panther Creek. About 4.7 miles of upper
Northeast Creek is designated as class C' water and the remaining length is designated as a
class WS-IV water 2. These sections of the stream are located in sub -basin 030605.
The 303(d) process requires that a Total Maximum Daily Load (TMDL) be developed for
each of the waters appearing in category 5 of the 2002 Integrated Report. 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
1 Class C waters are freshwaters that are protected for secondary recreation, fishing, aquatic life including
propagation and survival of wildlife.
2 Class WS-IV waters are freshwaters that are protected for water supply, secondary recreation, fishing, and
aquatic life, including propagation and survival of wildlife.
Northeast Creek Fecal Coliform TMDL
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).
Section 303(d) of the CWA and the Water Quality Planning and Management regulation
(USEPA, 2000a) requires EPA to review all TMDLs for approval or disapproval. Once
EPA approves a TMDL, then the water body may be moved to category 4a of the Integrated
Report. Water bodies remain on category 4a 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 restore 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 Northeast 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.
Northeast Creek flows from Durham to Chatham counties in the piedmont region of North
Carolina (Figures Iand 2). It is a tributary to the New Hope River arm of B. Everett Jordan
Reservoir (Sub -basin 030605) in the Cape Fear River Basin. Northeast Creek joins New
Hope Creek in the northeast corner of Chatham County, NC. The hydraulic length of
Northeast Creek is approximately 16 miles and the creek has a drainage area of
approximately 47 square miles. Land cover based on 1993-95 satellite data in the watershed
is primarily forest (86%), high intensity development land (6.5%), low intensity
development land (1.5%), managed herbaceous land (4.5%), unmanaged herbaceous land
(0.3%), cultivated land (0.2%) and water body 1 % (Figure 3). The dense coverage of the
developed

lands is often considered forestland. The annual average flow of the creek at the ambient
station near Nelson in Durham, is approximately 31.5 cubic feet per second (cfs), with a
7Q10 of 1.8 cfs (Weaver and Benjamin, 2001). The Creek is prone to become dry during
drought conditions (From DWQ staff s observation in 2002). It could be because the creek
drains Triassic Basin soils, which have high clay content and are slowly permeable sub -soils
with moderate to very high shrink -swell potentials. The watershed includes drainage from
the City of Durham, Research Triangle Park, Town of Cary, and the northeast portion of
Chatham County. Therefore, the watershed encompasses three counties — Durham County,
Wake County, and Chatham County.
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
2001100mL (MF count) based upon at least five consecutive samples examined during
any 30-day period, nor exceed 4001100mL 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 Northeast Creek
watershed, the water quality target is the 30-day geometric mean concentration of 200
colonies /100ml with no more than 20% of the samples in the same period exceeding 400
colonies / 100 ml.
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
5
Northeast Creek Fecal Coliform TMDL
(B3660000) in this watershed located at SR 1100 near Nelson (Figure 1). Fecal coliform
levels at SR1100 are responsible for the 303(d) listing of a portion of Northeast Creek.

Water body.
The Upper Cape Fear River Basin Association monitored the water quality at two additional
coalition stations - B3300000 and B3670000 near SR1102 (Sedwick Rd) and SR1731
(O kelly Church Rd) respectively during the years 2000 through 2002 (Figure 1). The DWQ
staff also monitored the water quality at the stations during 2002. The monthly fecal
coliform data is available for the years 2000 through 2002. The fecal coliform data
collected at these two stations offers the unique opportunity to compare the longitudinal
distribution of the bacterial concentration along the Northeast Creek. Figure 4 indicates that
the average bacterial concentration (598 counts/100ml) at the ambient station (133660000)
was nearly double the concentration (259 counts/ 100ml) at its receiving station (133300000)
in the year 2000. Furthermore, the bacterial concentration in the effluent discharged from
ro
Northeast Creek Fecal Coliform TMDL
the Durham Triangle WWTP to the ambient station was comparatively low, averaging 60
counts per 100 ml, which is below the DWQ standards. A similar pattern of bacterial
concentration is also observed in the year 2001 and 2002.
The substantial spike of fecal concentrations at the ambient station (B3660000) could be due
to a sewer pipe leaking or some other source between the coalition station (B3300000) and
the ambient station (B3660000). The influence of this unknown source, however, gradually
decreased moving downstream, as evident at the down stream coalition station (133670000).

DWQ staff also conducted an additional study at the ambient station (133660000) to
determine compliance with the fecal coliform standard. Weekly samples were collected
during November 1999 and during May, June, August, and September 2000. These
VA
Northeast Creek Fecal Coliform TMDL
additional samples also provided opportunity to calculate a 30-day geometric mean using 5
or more samples during that period. In most of the periods, the 30-day geometric mean of
the fecal coliform concentration at the ambient station remained considerably higher than
200 colonies / 100 ml. The 30-day geometric mean fecal coliform concentrations for 1997
through 2001 are shown in Figures 6-8.
In general, the fecal bacterial levels at the ambient station (133660000) are typical of fecal
coliform levels in many urban areas, with frequent concentration spikes. Out of 59 samples
collected during the study period at this station (1997 through 2001), 24 were exceeding 400
colonies / 100 ml (41 %). The monthly fecal coliform concentrations for 1997 through 2001
are shown in Appendix I.
The USGS flow station monitored stream discharges (cfs) every 15 minutes at the ambient
station (B3660000). These monitored discharge data were used to evaluate potential
compliance with the standard and to aid modeling studies. The discharge data is presented
in Appendix 2.
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 National Pollution Discharge Elimination System (NPDES) program. Wastewater
facilities have permitted discharges for which the DWQ has significant information.
Continuous discharge and/or wastewater 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 runoff producing storm events. The following sections describe
point and non -point sources of fecal coliform bacteria in the Northeast Creek watershed.
Northeast Creek Fecal Coliform TMDL
2.1 Point Source Assessment.
There are currently about 31 NPDES permits within the Northeast Creek watershed.
Twenty-eight of them are individual and general permits. Monitoring of water quality under
these permits is carried out once a year and measurement of fecal coliform is not mandatory.
So, the data from these permits are not considered for this study. The partial list of these
permits is presented in Appendix 6. Three out of the 31 permits are under regular NPDES
permit, where measurement of fecal coliform is mandatory (Table 1). One of them is
regulated under storm water program, which is commonly known as Municipal Separate
Storm Sewer System (MS4).
In 1990, EPA promulgated rules establishing Phase 1 of the NPDES storm water program.
The Phase I program for MS4 requires operators of medium and large MS4s, that is, those
that generally serve populations of 100,000 or greater, to implement a storm water
management program as a means to control polluted discharges from these MS4s. The
Storm Water Phase II Rule extends coverage of the NPDES storm water program to certain
"small" MS4s, which is not already covered by the Phase I program as a medium or large
MS4. The Phase II takes a slightly different approach to how the storm water management
program is developed and implemented (US EPA 2000).
EPA guidance mandates that all the urban areas that are documented as MS4 must be
categorized as point source (US EPA 2000). The two entities that are permitted through
Phase I of NPDES storm water program to discharge in the Northeast Creek watershed are
the City of Durham (NCS000249) and the North Carolina Department of Transportation
(NCS000250). As part of Phase II of the NPDES storm water program, Durham County,
which has jurisdiction over some land and storm pipes in the watershed, will be added.
In the Northeast Creek watershed, all the MS4 areas were located in Durham County. Out
of the 940 hectares of the developed lands in WS1 and WS2 (Table 5), about 223 hectares
(24%) of the lands were estimated to be draining to the MS4 areas. Of the 223 hectares, the
City of Durham MS4 represented 197 hectares and NC DOT MS4 represented 26 hectares (a
best estimation from Mr. John Cox, City of Durham).
9
Northeast Creek Fecal Coliform TMDL
Detailed information regarding the discharge rates and fecal concentration is not readily
available for storm water in the MS4 areas. The load from the MS4 areas is therefore
estimated by multiplying the total load discharged through the developed lands from the
percentage (24%) occupied by the MS4 areas.
McCarthy and Associates and the Durham Triangle WWTP are regulated under the NPDES
system. However, the McCarthy and Associates is not discharging and hence, it is not
considered in this study. The Durham Triangle WWTP discharges domestic and industrial
wastewater. The discharge is monitored for fecal coliform on a daily basis. The daily
average fecal coliform load from the facility is presented in Appendix 4.

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 Northeast 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.
In order to incorporate the actual amount of fecal coliform deposited from livestock, a
survey was conducted with the help of County Agents, Mr. Henry Outg (Chatham Co.), Mr.
Steve Woodruff (Wake Co.), and Ms. Karen McAdams (Durham Co), to enumerate the
approximate head count of livestock in the Northeast Creek watershed. The estimated head
count from this survey is presented in Table 3.
Table 3. Estimated Livestock in the Northeast Creek
Watershed.
Livestock I Durham Co. Wake Co. Chathem Co
Beef Cows 80 0

Horses 175 35

All of the beef cows are managed under the NC Agriculture Cost Share Program. The
program prohibits the grazing of the cattle near the stream. As the result, during a field
survey on January 15, 2000, DWQ staff and County agent, Ms. Karen McAdams, observed
11
Northeast Creek Fecal Coliform TMDL
no cattle grazing along Northeast Creek. They observed mainly horses grazing in the
managed herbaceous land near the creek.
Furthermore, DWQ staff observed that more than half of the herbaceous land (mostly grass
lands and crop lands), as identified by the 1996 land use data used for this study, have been
converted to low intensity development. It is, therefore, assumed that the impact of fecal
coliform due to the animal operations in the watershed should have been reduced by one
fourth of the actual load rates. The actual loading rates for livestock in the Northeast Creek
watershed were estimated to be 3000 to 7000 colonies per 100 ml. Fecal coliform
concentrations from grazed pasture runoff have been measured in the range of 120-1.3E+6
colonies/100 ml (Doran et al. (1981). The presence of cattle on rangelands increased fecal
coliform in stream concentrations from 0 to 2500 colonies per 100 ml (Khaleel et al.1980).
2.2.2. Domestic Animals
Dogs and cats are the major domestic animals in the watershed. As per the Durham County
Animal Control database, the population of dogs and cats in the county is estimated to be
37,396 and 19,230 respectively. In a study conducted by Hyer et. al, 2001, the bacterial
loads due to dog waste accounted for nearly 10 percent of the total bacterial load in three
creeks of Virginia, Accotink Creek, Blacks Run, and Christians Creek. In Melbourne,
Australia, dogs produced about 90 metric tons of feces each day - equivalent to the amount
of feces produced daily by 90,000 people
(http://www.esb.utexas.edu/nrm200l/dogdoo/WaterQuality(JJ)/Default.htm). Therefore a
separate study of the fecal loads due to dogs and cats is essential for cities like Durham.
During a survey, DWQ staff observed a considerable amount of dog waste along the creek
near residential areas. During a rainfall runoff event, a portion of the fecal material, which
contains coliform bacteria, is transported to the creek. Open lots used heavily by animals
have the greatest potential for bacteria loads to surface water. In addition, when animals
have direct access to streams, feces may be deposited directly into a stream. It is, therefore,
assumed that out of the total fecal coliform load estimated for urban development, 10% of
the load would have come from domestic animals.
12
Northeast 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
between 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).
2.2.2. Failed Septic Systems
Failing septic systems have been cited as a potential source of fecal coliform bacteria to
water bodies (DEH, 2000). About 18 percent of the residents in the Northeast Creek
watershed utilized septic systems (Table 4) and there were about 2.3 people per household
per septic system. A GIS map developed by the Soil Science Department, North Carolina
State University showing the spatial distribution of houses with septic and sewer systems in
the three counties (Durham, Chatham, and Wake) was utilized to estimate the number of
septic and sewer systems in the watershed. The number of houses with septic and sewer
systems in the counties were first divided by the respective areas of the counties. The
houses per area were then multiplied by the area of the watershed within each county to
estimate the total houses with sewer and septic systems in the watershed.

Frequent failures of the septic systems are common in the Durham County. This argument
is clearly made public by the daily NC newspaper, The News & Observer, on January 3, and
January 10, 2002. The City of Durham conducted field sampling of septic and sand filter
effluent during 1999 and 2000. The concentration of effluent fecal coliform bacteria due to
13
Northeast Creek Fecal Coliform TMDL
septic and sand filter effluent failure ranges from 11 to 490,000 counts/ 100ml based on
study conducted by City of Durham (Appendix 5). These data were used as a basis for fecal
coliform loads from failing septic systems for this study.
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 (discussed above), runoff through stormwater, sewers, illicit discharges/connections
of sanitary waste, leaky sewer systems, and sewer system overflows (Table 2). The sewage
pipelines to the WWTP run along Northeast Creek. In a record maintained by City of
Durham, the sewer pipe leaked four times in the year beginning May 2001 from the
residential and commercial properties and one time from the City Sanitary Sewer System.
Failures of connections between the sewer pipelines, or any leak from the pipe, could result
in profound fecal coliform loads to the creek.
Storm water runoff is the main carrier of solids, chemicals, and bacteria from urban sources,
including cross -connections with sanitary sewers. Various studies suggest that fecal coliform
counts in urban storm water typically range from 20 to 240,000 units per 100 ml (Farrell -
Poe et al., 1997, Khaleel et al., 1980, and Canale et al., 1993). The magnitude of the
bacterial concentration substantially increases with density of urbanization. Further
concentrations increase substantially during wet weather conditions. For example, dry
weather fecal coliform concentrations in Onondaga Lake and its seven tributaries in
metropolitan Syracuse, NY, ranged from 108 to 25, 525 colonies per 100 ml throughout the
summer of 1987 (Canale et al., 1993). Whereas, wet weather concentrations in the tributaries
ranged from more than 8,000 to 240,000 colonies per 100 ml. In general, significantly
higher colonies (11100,000 colonies / 100 ml) suggest the presence of cross connections with
sanitary sewers, which should be identified and corrected (Marsalek, 2002).
Because of the huge variation of fecal coliform concentration in urban storm water due to
interactions between the seasonal weather pattern and different urban characteristics, a
specific quantification of the fecal concentration in urban storm water for modeling purposes
is difficult. Due to lack of data on site specific fecal coliform loading from urban
14
Northeast Creek Fecal Coliform TMDL
development in the Northeast Creek watershed, the estimation of fecal coliform loading is
limited to best professional judgement based on the above studies. Marsalek (2002) suggests
that fecal coliform concentrations in urban storm water, where sewer cross connection
leaking is a problem, will exceed 100,000 colonies per 100 ml. Therefore, it is assumed that
the fecal concentrations in wet weather and dry weather storm water will be 50,000 and
30,000 colonies per 100 ml respectively, where frequent occurrences of sewer overflows
were observed. The wet weather period for this study was defined as the four consecutive
days following a storm event that produced surface runoff. Remaining days were labeled as
dry weather conditions.
These values were used to estimate total fecal coliform load from low intensity development
and high intensity development. These values were, however, adjusted during the model
calibration.
2.2.4 Wildlife (Background Source).
Wildlife deposit fecal material in forested, wetland, and herbaceous areas, which can be
transported to a stream in a storm event. Deposition of fecal coliform from wildlife
populations is natural. Therefore, wildlife is considered as a background source of fecal
coliform bacteria for this study.
Wildlife in the Northeast 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 15 to 30 animals per square
mile in the watershed (source: http://www.ncwildlife.org/pg07_WildlifeSpeciesCon). 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 to be 50 to
100 colonies per 100 ml. The Center for Watershed Protection (1999) has cited a fecal
coliform concentration range of 10-100 colonies per 100 ml for forest runoff.

3.0. MODELING APPROACH
3.1 Modeling Framework.
The watershed model named "The Coliform Routing and Allocation Program (CRAP)" was
selected for fecal coliform TMDL development for the Northeast Creek watershed. The
watershed model is designed to support the USEPA's protocol for estimating TMDL
calculation, allocation, and implementation. The model is a simple, flexible, steady-state
modeling tool. The model can be applied in a variety of watersheds for which there is a
limited available data. CRAP is a customized ArcView project, written in Avenue,
ArcView's scripting language. Output from the model is intended to represent `typical'
instream fecal coliform concentrations within a given time step, for predefined design
(critical) conditions.
The CRAP model estimates fecal loads for each source in each watershed using the
concentration based method with the equation 1:
L=C*Qlc*f ---
(1)
Where,
L = fecal load (cfu/day)
C = `typical' fecal concentration specified by the user(cfu/100mL). The user might choose
to think of this value as the fecal concentration measured in a stream draining a watershed
containing just the single source -associated land cover type.
Qlc = flow contributed by the source associated land cover within a given subwatershed (cfs)
f = factor to convert units of concentration and flow to cfu/day = 24,465,755.
The model estimates instream fecal coliform concentration by routing the total loads from
each sub -watershed downstream taking into account any variation in fecal decay rate
between sub -watersheds. The model utilizes the first order decay equation to estimate the
decay rate:
xt
Ct —Coe-------------------------------------------------------(2)
Where,
Ct is the coliform concentration (colonies/100 ml) at time t.
Co is the initial coliform concentration (colonies/100 ml).
k is the decay rate constant (per day).
16
Northeast Creek Fecal Coliform TMDL
t is the exposure time (days).
Generally, the decay rate (k) varies from 0 to 1.0 per day (Herr et al., 2000). In this study,
the decay rate was used as 0.1 per day.
The exposure time is estimated by dividing the travel distance by stream velocity. The
model estimates the stream velocity using the power function equation:
V=aQb----
---------------(3)
Where,
V is the stream velocity (ft per sec).
Q is the stream flow (cft per sec).
a is the flow coefficient (unitless constant).
b is the exponent coefficient for flow (unitless constant).
The constant coefficients, a and b, were estimated to be 0.32 and 0.24 respectively. The
estimation was done using the instream velocity measured by USGS at the ambient station
(133660000). The measured velocity is presented in the Appendix (3).
3.2 Model Setup.
The Northeast Creek watershed was delineated using the watershed delineation tool built in
the model. A total of six sub -watersheds (WS 1 to WS6) were delineated based on the Reach
file 3 (RF3) stream coverage for the Northeast Creek watershed (Figure I). The total
drainage area of the watershed was estimated to be 12206 hectares (47 square miles) with
hydraulic length of 16 miles (Table 5).
The dominant land cover in the watershed was forested lands. The second dominant land
use was developed lands. The two watersheds, WS1 and WS2, were within Durham County,
including City of Durham and Research Triangle Park and therefore, were dominated by
developed lands. Industrial and commercial developments were located primarily in the
Research Triangle Park. The rest of the watershed was dominated by herbaceous land.
The water quality data and flow data respectively collected by DWQ and USGS at the
ambient monitoring station (133660000) were utilized to calibrate the model. The station was
located in WS2 at about 3 miles below the WS1 (Figure 1).

3.2.1 Wet Weather Versus Dry Weather Fecal Coliform Loading
In this study, it is assumed that surface runoff would be generated in excess of infiltration
capacity of soil surface (maximum rate at which the soil can absorb water through the soil
surface at the time of entry) after each rainfall event. The infiltration capacity is determined
by soil type and moisture content. The soil type in the Northeast Creek watershed is Triassic
soil, which has comparatively low infiltration capacity due to heavy clay layers in the soils.
Owing to presence of clay, soil moisture holding capacity of the soil is reasonably high.
Therefore, wet weather conditions for the watershed were defined as three consecutive days
since the first flow rate increased at the USGS gauge station located at SR1100. The
increment was examined after subtracting the total flow from the flow from the WWTP to
account seepage from the watershed lands. Dry weather accounted for all the remaining
days. There were 59 observed data at SR1100, of which 36 were estimated to be dry
weather and the remaining 23 were to be wet weather period. Similarly, out of the 1826
Northeast Creek Fecal Coliform TMDL
simulation days, 846 days were estimated to be wet weather and the remaining 980 were dry
weather during the study periods.
A partial correlation between flow and fecal coliform concentration during the wet weather
and dry weather period was estimated. The correlations were 0.47 and 0.17. The result
suggests that the correlation was significantly higher during wet weather periods, signifying
that the assumption of the weather period was acceptable.
3.3 Model Calibration.
The watershed model was calibrated with fecal coliform concentrations observed at the
ambient station (B3660000). Since the station was located above the outlet of WS2, the
concentration of fecal coliform at the station was estimated using a proportional decrease in
concentration between the inlet and the outlet of WS2. The formula used for the estimation
of the concentration at the ambient station is as follows:
((Ci — Co)/Dio)*Doa) + Co------------------------------------(4)
Where,
Ci = Concentration at the inlet of WS2.
Co = Concentration at the outlet of WS2.
Dio = Hydraulic distance of Northeast Creek in WS2 = 4.35 mile.
Doa = Hydraulic distance of ambient station from the outlet = 1.43 mile.
In the calibration process, the decay rate of the fecal coliform bacteria in the stream was set
to 0.1. The input parameters estimated in § 2.2.3 for urban development were also further
adjusted to associate the estimated fecal coliform concentration with the observed
concentration. The adjusted concentrations were 40,000 colonies and 55,000 colonies per
100 ml of water during dry weather and wet weather periods respectively. Except for the
first simulation year, 1997, an acceptable association between the simulated fecal coliform
bacterial concentration and observed bacterial concentration was observed when the
estimated parameters were adjusted for wet weather and dry weather periods (Figure 5).

The association was further comprehensible when the observed and simulated values were
examined by estimating 30-day geometric mean (Figures 6, 7, and 8). This association could
not be examined for the simulated five-year period since minimum of 5 samples a month is
required for the comparison. The DWQ ambient monitoring station only has fecal coliform
samples on a monthly basis. Therefore, the DWQ staff conducted a special study program
to collect five samples in 30 days at the DWQ ambient monitoring site (SR 1100) during the
summer periods of 1999 and 2000. These data were merged with the regular ambient data to
have comparable geometric mean. The resulting 30-day geometric mean of the fecal
coliform concentration is presented in Figures 6-8.

The association between the 30-day geometric mean of observed and predicted fecal
coliform concentrations was somewhat weak for 1999 (Figure 6). The model estimated
considerably higher fecal coliform concentration than the observed concentration. It could
be either due to the estimation of higher initial fecal coliform concentration for the model
input in order to be consistent with the following years' developments in the watershed, or
could be due to model uncertainty (discussed below). However, the association was
significantly improved in the following years 2000 (Figures 7 and 8).

Northeast Creek Fecal Coliform TMDL
3.4 Model Uncertainty
The weak agreement between modeled and observed fecal coliform concentrations as
described in Section 3.3 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, and land use information. The
model, CRAP, selected to guide initial decision making, is not able to characterize
prediction uncertainty. The model estimates daily average fecal coliform concentrations
based on land use information and stream flow. The model does not consider the
contribution of stream temperature to the fecal decay rate. Also, because of lack of a site -
specific information, professional judgement 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 Loading
The model outputs indicate that the primary source of fecal coliform bacteria loads to
Northeast Creek is the direct input from both the non -point and point sources (Table 6). The
load due to non -point sources was almost three times (76%) higher than that of point sources
(24%). Among the point sources, the load due to the Durham Triangle WWTP discharge
was 1.95E+10 colonies per day (0.53%), whereas the load due to the MS4 areas was
8.59E+11 colonies per day (23%).
Among the non -point sources, areas of high intensity development appeared to contribute
high loads to Northeast Creek (60%). High intensity development includes lands where
more than 80% of lands are covered by synthetic coverage. Any coverage between 50% and
80% is considered as low intensity development. The loads due to low intensity
development were comparatively low (12%).
23
Northeast Creek Fecal Coliform TMDL
Urban development, animal grazing, and septic system contribute relatively higher fecal
coliform loads. In urban areas, fecal coliform can be contributed to all creeks by dogs, cats,
raccoons, stormwater runoff, and human waste during storm events. The DWQ staff
hypothesizes that the bacterial load due to the domestic pets accounts for about 10 percent in
the watershed. However, a study to track bacterial sources is required to quantify the actual
sources.
The relative contribution due to wildlife, livestock, and other sources (e.g., wetland and
water pond) was relatively low (❑1%).

3.5.2 Critical Period
The critical period is the period when the geometric mean of fecal coliform concentration
reaches peak levels, exceeding the water quality standard of 200 colonies / 100 ml. Fecal
coliform pollution in Northeast Creek watershed originated from both point and non -point
24
Northeast Creek Fecal Coliform TMDL
sources. Usually, excessive concentrations during the dry weather periods are due to point
sources, while excessive concentration during the wet weather periods are due to non -point
M61"iK13
Extreme flows might carry excessive amount of fecal colifrom from both point and non -
point sources to the Northeast Creek. In this study, the extreme flows were defined as the
flows that were exceeded less than 10 percent of the time (90th percentile) during the five
years simulation period. These flows were considered anomalous and were excluded to
estimate the critical period.
Extreme flows were determined by plotting flow duration curve (Figure 9). The duration
curve represents the flow data from October 1982 through September 2002. The duration
curve suggests that the flow that was equal to or above 56 cfs occurred less than 10 percent
of time in the Northeast Creek. The flows below 56 cfs were hence considered for
estimating critical period.

Northeast Creek Fecal Coliform TMDL
The highest 30-day geometric mean of the predicted daily fecal coliform concentration
occurred during wet weather on January 27, 2000 and May 24, 2000 (Appendix 7).
The respective fecal coliform concentration was 503 colonies per 100 ml and 491 colonies
per 100 ml. The difference between the two concentrations was only 12 colonies per 100
ml, which is indeed very close. The result suggests that wet weather is the critical period for
all the seasons in the Northeast Creek watershed.
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 effluent limitations and water quality. This
definition can be expressed by equation 5:
TMDL = ❑WLAs + ❑LAs + MOS---------------(5)
The objective of the TMDL is to estimate allowable pollutant loads and to allocate to the
known pollutant sources 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 was allocated for the ambient station at SR1100 in order to facilitate monitoring
of water quality after the TMDL implementation in future. There was a strong relationship
between the ambient station and the watershed outlet (Figure 10) based on the modeling
26
Northeast Creek Fecal Coliform TMDL
results. The predicted fecal coliform concentration at the outlet of the watershed can be
determined by using the following linear equation 6:

with regards to the simulated fecal coliform concentrations.
Concentration at outlet = 0.5031 * Concentration at ambient station — 1.555------------(6)
The coefficient of determination (R-Square) was found to be 0.99 for Equation 6. The result
suggests that the variation of the fecal coliform concentration in the watershed outlet is
significantly affected by the variation of the ambient station. The result also suggests that
the variation due to the fecal coliform concentration from the sub -watersheds (WS3 through
WS6) below the station was significantly low.
The TMDL was determined by systematically reducing the watershed loads until all 30-day
geometrical mean concentrations were below the TMDL target of 175 colonies / 100 ml
(marginal of safety = 25 colonies / 100ml). The resulting reduction is presented in Figure 11
for the study period, 1997 through 2001. During the entire study period, the reduction
27
Northeast Creek Fecal Colifonn TMDL
remained below or equal to TMDL target of 175 colonies / 100 ml. None of the fecal
coliform concentration in the same study period exceeded 400 colonies / 100 ml.

Figure 11. 30-day rolling geometric mean of the simulated fecal colifrom concentration
before and after TMDL allocation at the ambient station (B3660000).
The TMDL for both point source and non -point source was estimated by multiplying the 30-
day geometric mean simulated by the model after reduction by the respective flow values.
The TMDL was then proportionally distributed to each of the sources. The estimation was
done for the period when the maximum 30-day geometric mean was simulated. The existing
average daily load of fecal coliform bacteria at the ambient station is 3.67E+12 colonies /
day (Table 8). The TMDL load at the same location is 3.52E+11 colonies/day.
4.2 Seasonal Variation.
Seasonal variation was incorporated in the continuous simulation of the CRAP model by
using varying loading rates for wet and dry weather periods under varying daily flow
conditions for 5 years, 1997 through 2001. The variation of the predicted and observed fecal
Northeast Creek Fecal Coliform TMDL
coliform bacteria was remained high during both wet and dry weather periods. The
concentration level remained greater than the water quality standard (200 colonies / 100 ml)
for about 70% of the simulation period (Figure 11).
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
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 5.06E+10 colonies. The estimation was performed by calculating the
differences between TMDL with MOS and TMDL without MOS using the equation 2.
4.4. Waste Load Allocation.
The fecal coliform loads in the Northeast Creek watershed due to point sources were about
24% of the total load (Table 6). This percentage of fecal coliform bacteria was attributed to
the two main sources, the Durham Triangle WWTP and the MS4 areas. Both sources
respectively contributed daily fecal coliform load about 1.95E+10 colonies and 8.59E+11
colonies in the ambient site.
The Durham Triangle WWTP was permitted to discharge a monthly geometric mean fecal
coliform concentration of 200 colonies / 100 ml with a maximum permitted discharge of 6
MGD. The total permitted load of fecal coliform bacteria is thus estimated to be 4.54E+10
colonies per day, which is indeed substantially higher than the actual discharge load,
1.95E+10 colonies per day (Table 6). Therefore, a waste load allocation (WLA) reduction
was not recommended for the Durham Triangle WWTP.
However, about 92% of the existing load (8.59E+11 colonies per day) from the MS4 areas
should be reduced. The estimated TMDL for the MS4 areas are about 6.68E+10 (Table 8).
29
Northeast Creek Fecal Coliform TMDL
4.5 Load Allocation (Non -point Source).
The fecal coliform load in Northeast Creek watershed due to non -point sources was about
76% of the total load (Table 6). The model estimation suggests that the TMDL for the non -
point sources be 2.40E+11 colonies per day. On average, the total reduction required to
meet the water quality standard, 175 colonies per 100 ml, is thus estimated to be 91 %
(Table 8).

The load allocation distribution for the non -point source was mainly targeted to urban
developed areas, because developed areas contributed substantial fecal coliform bacteria to
Northeast Creek. Fecal coliform bacteria from developed areas can originate from various
sources including leaking sanitary sewers, illicit sanitary sewer connections, and storm water
runoff. Storm water runoff can include waste from domestic animals and urban wildlife.

Northeast Creek Fecal Coliform TMDL
Furthermore, the model results suggest that a substantial amount of fecal coliform bacteria
were transported to Northeast Creek from the developed areas in the City of Durham
(outside of the MS4 area) and Research Triangle Park. The total contribution of fecal
coliform bacteria is estimated to be 2.65E+12 colonies per day. About 92-94% of the load
needs to be reduced to meet the water quality standard (Table 8).
Similarly, about 90% of the loads (1.26E+11 colonies) from the herbaceous lands need to be
reduced to meet the water quality standard. Domestic animals and wildlife were seen to be
the main sources of fecal coliform from these lands. Fecal coliform loads from the forested
lands are considered as background sources in this study and hence, the reduction is not
recommended.
Overall, the total fecal coliform load observed in the ambient station, B3660000, was
3.68E+12 colonies per day during the study periods, 1997 through 2001. The estimated
TMDL required to meet the water quality standard, 175 colonies per 100ml of water, at the
station was 4.03E+I I colonies per day. The detailed estimated proportional reductions
required for the various sources in the Northeast Creek watershed are presented in Table 8.
5.0 SUMMARY AND FUTURE CONSIDERATIONS
The CRAP model estimated that the non -point sources contributed 76% of the total load
(3.68E+12 colonies per day) in the Northeast Creek. The contribution was primarily due to
urban development. In order for the water quality target to be met, the final allocation of the
fecal coliform bacteria requires a reduction of 2.40E+11 colonies per day for the various
non -point sources.
The pipelines connecting between the Durham Triangle WWTP and the sewage collection
system in the watershed run along the main Northeast Creek. Failure of connection between
the sewer pipelines or any leak from the pipe could result in profound fecal coliform loads in
31

the creek. The city of Durham and the respected line agencies are therefore suggested to
check any leak from the connecting pipe.
The model estimated that the point sources contributed about 24% of the total loading in the
watershed. A majority of that load was contributed by storm water runoff from the City of
Durham MS4 area. About 92% of the load (8.59E+11 colonies per day) was estimated to be
reduced to meet the water quality. In contrast, the reduction is not recommended for fecal
coliform loading from the WWTP. The waste load allocation for the WWTP, in accordance
with the NPDES permit, was estimated to be 4.54E+10 colonies per day. The permitted load
appeared to be marginally higher than the actual discharged load, 1.95E+10 colonies per
day.
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.
To comply with EPA guidance, North Carolina may adopt new bacteria standards utilizing
Escherichia coli (E. coli) or enterococci in the near future. Thus, in future, monitoring
efforts to measure compliance with this TMDL should include using E. coli or 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 initiate the development of an implementation plan.

6.0 PUBLIC PARTICIPATION
Many local government officials have been notified of DWQ's intention to develop the
Northeast Creek fecal coliform TMDL. The extension services in Durham County,
Chatham County, Wake County and local associations have supplied septic data, sewer data,
agricultural information, and stormwater runoff in MS4 areas to aid in the source assessment
portion of the TMDL. The Northeast Creek Fecal Colifom TMDL was public noticed
through local newspapers, The Herald -Sun and The Chatham Record, on May 6 and May 8,
2003 respectively (Appendix 8). The TMDL was also public noticed through DWQ web site
at httD://h20.enr.state.nc.us/tmdl/.
A public meeting was held in Durham County Agricultural Building and Curb Market, NC,
on May 27, 2003 as a part of the comment period. A group of eight (8) individuals
participated the meeting from the following organizations:
City of Durham, Stormwater Services — 5 representatives
Cooperative Extension Service — 1 representative
Raleigh Regional Office — 2 representatives
A public comment period was through June 5, 2003. No written comments were received.
