Stream Monitoring Site and Period of Record: Active KDHE rotational ambient
stream chemistry sampling station SC578 located on Salt Creek near Lyndon. Sampled
during the years of 1990, 1994, 1998, 1999, 2000, 2002, 2006, and 2010.

-------
Flow Record: USGS gage 06911490 on Salt Creek at Lyndon (1999-2012) and USGS
Gage 06911500 on Salt Creek near Lyndon (1988-1999) were utilized to establish flow
conditions in the watershed. The USGS gage 06911490 is located at the same location
of the KDHE sampling station. For samples collected prior to the use of this gage (prior
to October of 1999) the flow values for each sampling date are based on USGS gage
06911500, which is just downstream of the sampling point a few stream miles.

Precipitation: The average annual rainfall in the watershed is approximately 39.5
inches/year.

Current Condition: Since loading capacity varies as a function of the flow present in
the stream, this TMDL represents a continuum of desired concentrations over all flow
conditions, rather than fixed at a single value. Sampling data from station SC578 is
categorized into three defined seasons: Spring (April-June), Summer-Fall (July-October)
and Winter (November-March).

Dissolved Oxygen (DO) concentrations on Salt Creek are observed in Figure 2. All of
the impairments associated with the DO deficiency are observed during the low flow
condition, with one violation occurring in late Spring and the rest of the violations
occurring in the Summer-Fall season as seen in Table 2. The majority of the impairments
have occurred during the hot month of August. The overall annual averages were not
below 5 mg/L during any of the sampling years as seen in Table 3. A monthly summary
of the frequency of impairment is detailed in Table 4 and Figures 3 and 4. The monthly

3

-------
average DO concentrations are below 5 mg/L during the months of August and
September. The annual seasonal averages, as seen in Figure 5, are below 5 mg/L during
the summer-fall seasons during 2000, 2002, and 2006.

The years of 1999 and 2000 were sampled more than any other sampling year. Samples
were collected monthly during these two years, which indicates this station was
programmatically selected for more intensive sampling for these two years. According to
the regular schedule for rotational sampling stations, SC578 is a rotational station that is
sampled on a quarterly bases every fourth year. The regularly scheduled rotational
sampling years include 1990, 1994, 1998, 2002, 2006, and 2010.

Stream temperatures also influence DO concentrations in Salt Creek, where higher
temperatures along with the low flow condition are common with DO violations.
Seasonal average DO concentrations indicate that concentrations are the lowest in the
Summer-Fall season as seen in Table 3 and Figure 6.

Streamflows with the least amount of flow occur during the Summer-Fall season and
correspond well with the months with the lower average monthly DO concentrations.
Monthly rainfall averages tend to have a similar pattern as the average streamflow within
the watershed as seen in Figure 7.

There are lower DO concentrations in the summer-fall season when stream temperatures
are elevated as illustrated in Figure 8. There is a negative relationship between DO
concentrations and stream temperatures and a positive relationship between DO and pH
in Salt Creek as illustrated in Figures 9. The pH values are generally higher with
elevated DO concentrations and decrease with lower DO concentrations. There are no
discernible relationships between DO concentrations and total phosphorus or total
suspended solids.

Desired Endpoints of Water Quality (Implied Load Capacity) in Salt Creek:

The ultimate endpoint for this TMDL will be to achieve the Kansas Water Quality
Standards fully supporting aquatic life support, indicated by dissolved oxygen
concentrations of 5 mg/L or more. Seasonal variation is accounted for by this TMDL,
since the TMDL endpoint is sensitive to the low flow and temperature conditions usually
occurring in the Summer-Fall season and higher DO levels occur during the periods of
higher sustained flow. Low flow periods aggravate situations of deficient dissolved
oxygen within this watershed. Achievement of the endpoint indicates any loads of
oxygen-demanding substance are within the loading capacity of the stream, water quality
standards are attained and full support of the designated uses of the stream has been
restored.

3. SOURCE INVENTORY AND ASSESSMENT

Land Use: The land cover in the Salt Creek watershed is dominantly grassland and
cropland. Table 5 further details the percentages of all landuse acres in the watershed.
As seen in Figure 10, cropland is the predominant land cover lying along the main
segments of Salt Creek.

Point Sources: There are four NPDES facilities located within the Salt Creek watershed
as seen in Table 6. The Builders Choice Concrete plant has a general concrete plant
permit to discharge overflow from their wash water basin. There has not been any
reported discharge from this facility since 2004. The Hamm Quarry facility is a
limestone quarry operation that is permitted to discharge storm water runoff and treated
wash water from a settling pond. There has not been any reported discharge from this
facility. The City of Osage City wastewater treatment facility utilizes a three-cell lagoon

n

-------
system. One of the permit limits is for Biochemical Oxygen Demand (BOD) (45 mg/L
weekly average and 30 mg/L monthly average), which requires quarterly sampling. The
average BOD concentration in the City of Osage City's effluent is 21.6 mg/L (see
Appendix C for BOD discharge data). The City of Lyndon wastewater treatment facility
is a mechanical plant with a design flow of 0.15 MGD that discharges to Salt Creek
below the KDHE monitoring station. This facility monitors DO concentrations in the
effluent along with BOD (limit of 45 mg/L weekly average and 30 mg/L monthly
average). The average DO concentration in the Lyndon effluent is 8.0 mg/L and the
average BOD concentration is 13.8 mg/L (see Appendix D for DO and BOD discharge
data). The City of Lyndon does not contribute to the Dissolved Oxygen impairment at
SC578 since the discharge is downstream from the monitoring station.

Contributing Runoff: The watershed of Salt Creek has a mean soil permeability value
of 0.41 inches/hour, ranging from 0.01 to 1.29 inches/hour according to the NRCS
STATSGO database. According to a USGS open-file report (Juracek, 2000), the
threshold soil-permeability values that represents very high, high, moderate, low, very
low, and extremely low rainfall intensity, were set at 3.43, 2.86, 2.29, 1.71, 1.14, and
0.57"/hour, respectively. The lower rainfall intensities generally occur more frequently
than the higher rainfall intensities. The higher soil-permeability thresholds imply a more
intense storm during which areas with higher soil permeability potentially may contribute
runoff. Runoff is chiefly generated as infiltration excess with rainfall intensities greater
than the soil permeability. As soil profiles become saturated, excess overland flow is
produced. For the Salt Creek watershed, runoff will be produced by a rainfall event
producing 1.14 inches/hour rain in approximately 61% of the watershed, and a rainfall
event producing 1.29 inches/hour of rain will produce runoff over the entire watershed
based on the soil permeability values in the watershed.

Livestock Waste Management Systems: There are eleven certified or permitted
confined animal feeding operations (CAFOs) within the Salt Creek watershed (see
Appendix A). These facilities are designed to retain a 25-year, 24-hour rainfall/runoff
event as well as an anticipated two weeks of normal wastewater from their operations.
Typically, this rainfall event coincides with streamflow that occurs less than 1-5% of the
time. Though the total potential number of animals is approximately 4,070 head in the
watershed, the actual number of animals at the feedlot operations is typically less than the
allowable permitted number.

-------
According to the Kansas Agricultural Statistics, as of January 1, 2011 the estimated
number of all cattle and cows for Lyon and Osage counties are 65,000 and 34,000
respectively.

On-site Waste Systems: Households outside of the City of Lyndon and Osage City are
presumably utilizing on-site septic systems. The Spreadsheet Tool for Estimating
Pollutant Load (STEPL) was utilized to identify the number of septic systems within the
HUC12s within the watershed. According to STEPL, there are approximately 389 septic
systems within the Salt Creek watershed with an anticipated failure rate of 0.93%. On-
site septic systems are likely an insignificant source contributing to the dissolved oxygen
impairment within the Salt Creek watershed.

Background: The natural hydrologic characteristics of the watershed influence DO
concentrations during periods of low flow that are prevalent during the warmer summer
months. Leaf litter and wastes derived from natural wildlife may add to the nutrient load.

Relationship with Other Parameters: Based on the assessment it is apparent that
dissolved oxygen deficiencies are driven by low flow conditions and higher stream
temperatures. Violations that occur during these conditions are likely natural occurrences
based on the hydrodynamics of the stream system since the stream is likely lacking
sustained flows during these periods. During these conditions the aquatic life use is
ultimately impaired by the lack of flow, which may be accompanied by the pooling of
water within the streambed.

Figures 11 and 12 display comparisons of data sets based on compliant and non-
compliant DO samples. The compliant data set consists of 44 samples compared to the
seven noncompliant DO samples at SC578. There are some distinct observations
between the datasets. The pH values for the compliant DO samples are higher than the
non-compliant samples. Temperatures are higher and the percent of flow exceedance
values are much lower for samples that violated the DO standard as seen in Figure 12.
Figure 13 breaks out a comparison between low flow (50-99% flow exceedance) and
high flow (0-49%) flow exceedance) samples relative to the sampling period as detailed
by the critical and non-critical sampling periods. Where the critical sampling period
encompasses samples collected during the months when DO violations occurred, which
includes the period from June through October. The non-critical period includes the
months of January, February, March, April, May, November and December where no DO
violations have been observed.

4. ALLOCATION OF POLLUTION REDUCTION RESPONSIBILITY

The TMDL is a concentration based TMDL, where all stream segments within the
watershed must maintain a Dissolved Oxygen Concentration of 5 mg/L or more at all
times that the stream has sustained flow. There is some degree of uncertainty on
establishing allocations under this TMDL. Total Organic Carbon (TOC) will be allocated
under this TMDL as the pollutant to meet the DO TMDL, though ultimately success of
this TMDL will be measured through in stream DO compliance. Additionally the DO
impairment is related to the low flow condition and may be attributed to hydrological
conditions.

KDHE discontinued sampling for Biochemical Oxygen Demand (BOD) in 2001 and
began utilizing Total Organic Carbon (TOC) analyses in late 2000 in lieu of BOD.

KDHE conducted analyses in 2000 to determine if TOC concentrations could be utilized
as a surrogate for BOD and whether a statistical translation could be made for this
expression. KDHE utilized 675-paired sets of data in the analyses and concluded that
there are relationships in the stream data. "The data suggest that, for effluent and point
source related waters, the BOD/TOC ratio is almost one-to-one. Ambient waters have
much lower ratios, suggesting that a portion of the TOC is in more refractory substances
(i.e., cell walls, lignin, cellulose, etc.)" (Carney, 2000). The analysis of the paired

-------
ambient stream data was utilized for this report. The regression analyses for this group is
summarized as follows:

R square = 0.34
P Value = <0.0001

For a TOC value of lOmg/L, the most likely BOD concentration = 4.31 mg/L
Lower 95% BOD = 3.34 mg/L
Upper 95% BOD = 5.29 mg/L

BOD/TOC Ratio:

Arithmetic Mean = 0.44
Geometric Mean = 0.35
Median = 0.37

Generally, higher BOD and TOC concentrations indicate that more oxygen will be
consumed by an ecosystem, which may result in an oxygen deficient stream system as the
population increases among microorganism communities. The average TOC
concentration for Salt Creek is 7.6 mg/L under all flow conditions. The average BOD
concentration for the samples collected prior to 2003 is 2.75 mg/L. The critical period
when DO violations occurred is from June through October. The average TOC
concentration during the 50 to 99% flow exceedance range is 7.71 mg/L for the critical
period. The monthly periods from January through May, along with November and
December consists of the months where no DO violations have occurred and is
considered the non-critical period. During these months the average TOC concentration
during the low flow range (50-99% exceedance) is 7.42 mg/L. The average BOD/TOC
Ratio at SC578 is 0.36 and the median ratio is 0.39.

TOC will be allocated for all flow conditions based on the data set of low flow (50-99%
flow exceedance) samples at SC578 during the non-critical months consisting of January,
February, March, April, May, November and December, with an average TOC
concentration of 7.42 mg/L. These allocations are conservatively set for all flow
conditions since there are no DO violations at the higher flow condition from the 0-49 %
flow exceedance range.

Point Sources: Since the DO violations are associated with critically low flow events
from June-October it is conceivable that point sources are not contributing to the DO
impairment. Wasteload Allocations (WLA) will be assigned to the two wastewater
treatment facilities based on 30 mg/L BOD monthly averages and the design flow for
these facilities. The WLA is 111.5 lbs/day of BOD as detailed in Table 7. Based on the
discharge monitoring reports, the City of Lyndon and Osage City have BOD averages in
their effluent well below the established limits and it is therefore anticipated that these
facilities will be well under the assigned WLA throughout the year. The equivalent TOC
WLA for these two facilities is 301.4 lbs/day. This translates to an in-stream TOC WLA
of 27.57 lbs/day, based on the design flows for the facility and the TOC concentration
(7.42 mg/L) target at SC578. The WLA associated with the City of Lyndon enters Salt

-------
Creek below KDHE sampling station SC578. As detailed in Appendix B, the WLA is
zero for the other two permitted facilities within the watershed.

Defined Margin of Safety: The margin of safety provides some hedge against the
uncertainty of daily loading that contributes to the impairment of dissolved oxygen
deficiencies. This TMDL uses an implicit margin of safety, relying on conservative
assumptions made with wastewater facilities assuming they discharge permitted BOD
concentrations at design flow. Additionally, the allocations are conservatively set for all
flow conditions when the impairment occurs only during the low flow condition during
the critical months from June through October along with higher stream temperatures.

State Water Plan Implementation Priority: Because low dissolved oxygen levels in
Salt Creek are often related to natural seasonal conditions resulting in higher
temperatures during times of lower flow, this TMDL will be a Low priority for
implementation.

Unified Watershed Assessment Priority Ranking: The Salt Creek watershed lies
within the Upper Marais des Cygnes Subbasin (HUC8: 10290101) with a priority ranking
of 5 (High Priority restoration work).

18

-------
Priority Stream segments: Because of the lack of certainty regarding potential sources
and naturally occurring background concentrations in the watershed, no priority
subwatershed or stream segment will be identified.

5. IMPLEMENTATION

Desired Implementation Activities

1.	Install grass buffer strips where needed along streams.

2.	Maintain adequate streamflow by ensuring streamflow is not artificially reduced
or impeded, particularly during low flow durations.

3.	Ensure that labeled application rates of chemical fertilizers are being followed and
implement runoff control measures.

4.	Implement nutrient management plans to manage manure land applications and
runoff potential.

5.	Ensure appropriate treatment of wastewater through compliance of NPDES limits.

Implementation Programs Guidance

a.	Support Section 319 demonstration projects for reduction from streambank
erosion, sediment runoff, and livestock operations.

b.	Provide technical assistance on practices geared to the establishment of
vegetative buffer strips.

NPDES and State Permits - KDHE

a.	Livestock permitted facilities will be inspected for integrity of applied
pollution prevention technologies.

b.	Registered livestock facilities with less than 300 animal units will apply
pollution prevention technologies.

c.	Manure management plans will be implemented.

d.	Municipal wastewater is below BOD limits.

Riparian Protection Program - KDA Divison of Conservation

a. Establish or re-establish natural riparian systems, including vegetative filter
strips along small tributaries.

Buffer Initiative Program - KDA Division of Conservation

a.	Install buffer strips near streams.

b.	Work in conjunction with Federal Conservation Reserve Enhancement
Program and Conservation Security Program to hold marginal riparian land
out of production.

Timeframe for Implementation: Continued monitoring over the years from 2013 to
2022.

19

-------
Milestone for 2017: In accordance with the TMDL development schedule for the State
of Kansas, the year 2017 marks the next cycle of 303(d) activities in the Marais des
Cygnes Basin to review data from the Salt Creek watershed to assess continued incidence
of dissolved oxygen deficiencies.

Delivery Agents: The primary delivery agents for program participation will be the
Kansas Department of Health and Environment.

Reasonable Assurances:

Authorities: The following authorities may be used to direct activities in the watershed to
reduce pollution.

1. K. S. A. 65-171 d empowers the Secretary of KDHE to prevent water pollution
and to protect the beneficial uses of the waters of the state through required
treatment of sewage and established water quality standards and to require
permits by persons having a potential to discharge pollutants into the waters of
the state.

2. K.S.A. 65-164 and 165 empowers the Secretary of KDHE to regulate the
discharge of sewage into the waters of the state.

3. K.S.A. 2002 Supp. 82a-2001 identifies the classes of recreation use and
defines impairment for streams.

4. K.A.R. 28-16-69 through -71 implements water quality protection by KDHE
through the establishment and administration of critical water quality
management areas on a watershed basis.

5. K.S.A. 2-1915 empowers the State Conservation Commission to develop
programs to assist the protection, conservation and management of soil and
water resources in the state, including riparian areas.

6. K.S.A. 75-5657 empowers the State Conservation Commission to provide
financial assistance for local project work plans developed to control nonpoint
source pollution.

7. K.S.A 82a-901, et seq. empowers the Kansas Water Office to develop a state
water plan directing the protection and maintenance of surface water quality
for the waters of the state.

8. K.S. A. 82a-951 creates the State Water Plan Fund to finance the
implementation of the Kansas Water Plan, including selected Watershed
Restoration and Protection Strategies.

9. The Kansas Water Plan and the Marais des Cygnes Basin Plan provide
guidance to state agencies to coordinate programs intent on protecting water

-------
quality and to target those programs to geographic areas of the state for high
priority in implementation.

Funding: The State Water Plan Fund annually generates $16-18 million and is the
primary funding mechanism for implementing water quality protection and pollutant
reduction activities in the state through the Kansas Water Plan. The state water planning
process, overseen by the Kansas Water Office, coordinates and directs programs and
funding toward watersheds and water resources of highest priority. Typically, the state
allocates at least 50% of the fund programs supporting water quality protection through
the WRAPS program. This watershed and its TMDL are a Low Priority consideration.

Effectiveness: Buffer strips are publicized as a means to filter sediment before it reaches
a stream and riparian restoration projects have been acclaimed as a significant means of
stream bank stabilization. The key to effectiveness is participation within a targeted area
to direct resources to the activities influencing water quality. Secondary wastewater
treatment is very effective at reducing BOD in effluent.

6. MONITORING

KDHE will continue to collect samples through 2022 at the rotational station SC578 on
Salt Creek on a quarterly basis every fourth year. Point source facilities will continue to
monitor BOD in their wastewater.

7. FEEDBACK

Public Notice: An active internet website was established at
http://www.kdheks.gov/tmdl/index.htm to convey information to the public on the
general establishment of TMDLs and specific TMDLs for the Marais des Cygnes Basin.
This TMDL was initially posted on website on May 3, 2013 for public review.

Public Hearing: A Public Hearing on the Marais des Cygnes River Basin TMDLs was
held on May 23, 2013 in Ottawa to receive comments. Public comments for this TMDL
were held open from May 4 through June 7, 2013. KDHE did not receive any comments
regarding this TMDL.

Basin Advisory Committee: The Marais des Cygnes River Basin Advisory Committee
met to discuss these TMDLs on September 14, 2012 in Fort Scott.

Milestone Evaluation: In 2017, evaluation will be made as to the degree of impairment
continuing to occur within the watershed. Subsequent decisions will be made regarding
the implementation approach, priority of allotting resources for implementation and the
need for additional or follow up implementation in this watershed at the next TMDL
cycle for this basin in 2017 with consultation from local stakeholders and the BAC.

-------
Consideration for 303(d) Delisting: Salt Creek will be evaluated for delisting under
section 303(d), based on the monitoring data over 2013-2022. Therefore, the decision for
delisting will come about in the preparation of the 2024-303(d) list. Should
modifications be made to the applicable water quality criteria during the implementation
period consideration for delisting, desired endpoints of this TMDL and implementation
activities might be adjusted accordingly.

Incorporation into Continuing Planning Process, Water Quality, Management Plan
and the Kansas Water Planning Process: Under the current version of the Continuing
Planning Process, the next anticipated revision would come in 2014, which will
emphasize implementation of WRAPS activities. At that time, incorporation of this
TMDL will be made into the WRAPS. Recommendation of this TMDL will be
considered in the Kansas Water Plan implementation decisions under the State Water
Planning Process for Fiscal Years 2013-2022.
