WATER QUALITY STUDY OF
                           BILLINSSLEY CREEK, IDAHO
EXECUTIVE SUMMARY

The study purpose was to evaluate  EPA's proposed trout hatchery permit limits
on Billingsley .Creek water quality. The proposed permit effluent limits are
technology based.  Total  suspended solids  (TSS), settleable solids, nutrients
(nitrogen and.phosphorus), ammonia, and dissolved oxygen were evaluated.  The
conclusions of the study are  summarized below:
           -,

1.  TSS levels resulting from the  proposed effluent limits will provide a high
    level of protection for the biota and comply with Idaho WQS.
          \      • *
2.  Settleable solids discharged from the hatcheries are a real concern for
    BIlHngsley Creek.

    The potential settleable  sol Ids load allowed by the proposed effluent
    limits is quite high.  If these proposed loadings were discharged to
    Billingsley Creek,  it would cause unacceptable Impacts to the stream.

    However, it 1s unlikely that the actual settleable solids loading would
    ever be as high as proposed.   Settleable solids are well below effluent
    limits when the TSS meets the  effluent limits.  The data from the JRB
    (1984) study indicated that the hatcheries can achieve trace levels of
    settleable solids in their effluents.  Also, the cleaning effluents which
    contain the higher solids load are only discharged sporadically.  But to
    ensure that the possible  loads under the proposed permit are never
    discharged, the permit limits  should be lowered for cleaning effluents and
    every effort made to minimize  sol Ids discharges.

    RECOMMENDATIONS

    a.   Lower the permit limit for cleaning effluents to 0.5 ml/1.

    b.   Emphasize the Importance  of developing operation plans that will
         minimize the discharge of solids.

    c.   Evaluate the effect  of settleable solids on the stream after a year
         and reopen the permit if  necessary.

3.  Nitrogen and phosphorus levels 1n BUlingsley Creek appear to be
    excessive.  Plant growth  in the stream is excessive and contributes to a
    significant diurnal oxygen swing.  However, the late night D.O. sag is
    short lived because of the short detention time of water in the stream.
    Further, D.O. never reached dangerous levels.  The lowest D.O. recorded
    was 5.0 mg/1.  The effluents contribute both nutrients to the stream
    system.  However, there is evidence that much of the nitrogen (at least
    the nitrites and nitrates) and some of the phosphorous may be in the
    spring water before it enters the trout hatcheci&s-

-------
    Phosphorus appears to be contributed  to the system by the hatchery
    operations.  However, Individual  hatchery discharges of phosphorus  are at
    quite low effluent concentrations and may be difficult to remove.

    RECOMMENDATIONS

    a.   Evaluate the effect of nutrients on the stream after a year and
         reopen the permit 1f necessary.

    b.   Emphasize the Importance of  developing operations plans that minimize
         the discharge of nutlents.

4.  The trout hatcheries appear to have little direct Impact on dissolved
    oxygen (DO) 1n BllUngsley Creek.  They may contribute Indirectly to
    depressed nighttime DO by discharging nutrients to the stream.  At this
    time there 1s no evidence that the diurnal dissolved oxygen swing has an
    adverse effect on the stream. As  recommended above the permit can be
    reopened 1f Impacts are detected. The state'has an ongoing study that
    should document any Impacts.

DESCRIPTION OF BILLINGSLEY CREEK

Bllllngsley Creek originates at Curren Spring 1n Goodlng County, approximately
3 miles from Hagerman, Idaho.  The stream flows just over 7.5 miles northwest
to Its confluence with the Snake River.   A number of spring fed streams are
tributary to BHHngsley Creek.  The  creek 1s also fed by Irrigation return
flows.

BUlingsley Creek flows primarily through agricultural lands with row crops,
pastures, and confined animal feeding operations.  Water is diverted from
Billingsley Creek for Irrigation at Curren Ditch near the headwaters, and at
numerous locations in the downstream  reaches.

There are four major trout hatcheries that discharge to Billingsley Creek:
Rangen Hatchery, Jones Hatchery, Idaho Springs, and Fisheries Development.
Rangen is located at the headwaters and utilizes Billingsley Creek  water for
all its raceways and ponds.  Virtually all the water in the creek immediately
below Rangen has passed through the hatchery.  During the irrigation season
all the water in the creek below Rangen can be diverted for irrigation  at
Curren Ditch, immediately below the hatchery at river mile 7:0.  Jones
Hatchery discharges to the creek at river mile 5.7.  This hatchery  utilizes
water from a spring.  During the non-irrigation season, flow in the creek
roughly doubles at Jones.  When water is  being diverted at Curren Ditch,
nearly all the flow below Jones results from the Jones effluent. The Idaho
Springs Hatchery discharges to BilUngsley Creek at River miles 3.9 and 3.8.
This hatchery withdraws water from Billingsley Creek for its rearing ponds.
It utilizes spring water for its raceways.  Idaho Springs was not in operation
during, this study.  Fisheries Development discharges to the stream  at river
mile 2.7, and it utilizes spring water.

The physical habitat and water quality of Billingsley Creek are both
indicative of extensive agricultural  and  aquacultural use.  JRB (1984)  found
Bi 11-irn.gsM ey Creek water quality to be inferior to comparable spring fed
streams primarily as a result of high nutrient levels.  JRB also reported
                                   - 2 -

-------
    heavy accumulations of organic material  below the trout hatcheries.   In
    addition, they observed extensive macrophyte  beds, especially downstream
    of hatcheries.  Overall, JRB  concluded  that BllUngsley Creek exhibits
    symptoms of a stressed stream system, attributable to the trout
    hatcheries, feedlot runoff, and grazing.

METHODOLOGY   -;.

Billingsley Creek and the four trout hatchery  effluents were sampled  in
January,-March, April,  May, and June.   Field data was collected by the Twin
Falls office of the Idaho Department of Health and Welfare, Division  of
Environment (DOE) and EPA's Environmental Services Division (ESD).  ESD  gauged
the stream in March and June and  analyzed water samples in the laboratory for
BOD5» 10» 15» 20» settleable solids, suspended solids, and nutrients.
The ESD BOD data was used for the dissolved oxygen model, but DOE data was
used for the rest of the analyses because it was  available for all sampling
dates.  The ESD data was used as  a quality  assurance check.

The following parameters were measured for  each station on each sampling date.

hatchery effluents on dissolved oxygen were evaluated using the STREAM
water quality model developed by Manhattan College.

All the data collected for  this study are listed In the Appendix to  this
study.  The field data for  parameters of primary concern In this study are
listed 1n Appendix Tables C and D for the stream stations and Table  E for
the effluents.  Statistical summaries of all the data are presented  in
Figures 1 and 2 and in Appendix Tables A and B for stream stations and
effluents respectively.

EFFLUENT QUALITY

Effluent quality was generally quite good with only the nutrients being at
excessive levels.  Figure 1 presents a statistical summary of all of the
effluent data.  Appendix Table A contains the data used to compile the
charts shown in Figure 1.
TSS were very low for all the effluents  (see Appendix Table A and E).
highest recorded value was 9.8 mg/1  from the Fisheries Development
settling pond.  The mean TSS levels  ranged from 3.7 mg/1  at the Jones
raceway to 7.9 mg/1 at the Jones settling pond.  Only two settleable
solids measurements were taken:  0.1 ml/I at the Rangen raceway and 0.1
ml/I at the Jones settling pond.

-------
The nutrients, phosphorus, and nitrogen were really quite low in the
effluents.  Phosphorus ranged from 0-0.49 rag/1.  The mean phosphorus
levels ranged fro« 0.054 rag/1 at the  Idaho Springs Raceway to 0.326 at the
Jones settling pond.  Mean nitrate/nitrite nitrogen levels ranged from
0.763 at the Fisheries Development settling pond to 1.148 at the Idaho
Springs Rearing Pond.  Mean total ammonia levels ranged from 0.029 mg/1 at
Idaho Springs raceway to 0.322 mg/1 at the Jones raceway.  Mean Kjeldahl
nitrogen ranged from 0.142 mg/1 at Idaho Springs raceway to 0.842 mg/1 at
Jones settling pond.

Oxygen levels were generally fairly high in the effluents.  The lowest
recorded dissolved oxygen level was 7.1 at the Rangen raceway and the
Jones settling pond.  Five day biochemical oxygen demand was generally
very low.  The maximum recorded was 8.7 mg/1 at the Jones settling pond.
The mean BOD at Jones settling pond was only 5.1 mg/1.  The highest mean
at the other dischargers was 2.8 mg/1 at the Jones raceway.

INSTREAM WATER QUALITY

The instream water quality of Billingsley Creek was generally quite good
during the study period (Appendix Tables C and D).  Only the nutrients,
nitrogen, and phosphorus were at concentrations that could cause water
quality problems.  A statistical summary of this data is presented in
Figure 2 and Appendix Table B.

Instream TSS ranged from a high of 24.0 mg/1 at Station 87 in January to a
low of less than 1.0 mg/1 at every station except Station 5 in June
(Appendix'Table B).  Station 5 had 1.0 mg/1 in June.  The data in Table D
indicates that TSS generally decreased at each station with season and
with flow.  Further, TSS decreased below the hatcheries on each sampling
date (see Appendix Figures 1-5).

Instream nutrient levels were fairly  high and constant throughout the
study.  Total phosphorus ranged from  0 to 0.2 mg/1.  Nitrate/nitrites
ranged from 0.72 to 9.2 mg/1.  Total,  ammonia ranged from .004 to .729
mg/1.  Kjeldahl  nitrogen ranged from  0.1 to 0.8 mg/1.  It is important to
note from Appendix Table C that the headwater station (Bl) consistently
had lower levels of phosphorus, ammonia, and Kjeldahl nitrogen than the
rest of the stream, but its nitrate/nitrite levels were in the same range
as the rest of the stream.

Un-ionized ammonia was very low at every station on every sampling date.
The highest readings were on May 22 at Stations 3 and 4; 0.075 and 0.019
mg/1 respectively.  The Station 3 level was apparently the result of high
pH (9.0) rather than an influx of ammonia because the total ammonia level
was only 0.350 mg/1.  This is very similar to Station B2 when the total
ammonia was 0.337 but the un-ionized  was only 0.0071 mg/1  The highest
un-ionized ammonia level at the other stations was 0.0097 mg/1 at
Station 86.

Dissolved oxygen was fairly high throughout the study (Appendix  Figures
1-5).  The lowest value recorded was 6.2 at Station B2 below the Rangen
hatchery on March 7, 1984.  Dissolved oxygen was supersaturated  1n much of
the stream during May and June.  At Station B3 oxygen levels of  19.5 mg/1
1n May and 14.2 rag/1 1n June were recorded.  At B5 the May concentration
was 14.8 and the June level was 12.6, and at B5A the May and June
concentrations were 12.0 and 11.2 mg/1 respectively.

STUDY RESULTS

The results of this study are summarized 1n three sections.   First, we
compare the actual trout hatchery effluents to the EPA established
effluent limits for such hatcheries.  Second, we summarize the Impact of
the trout hatchery effluent on Instream water quality.  Following these
summaries, we present a detailed pollutant-by-pollutant analysis of the
Impact of each pollutant on BllUngsley Creek.  Graphs are used  whenever
possible fn presenting data.  All data collected for this study  1s
compiled In the Appendix.

TSS

It Is quite evident that the hatchery effluents had little Impact on
Instream TSS during this study.  Appendix Figures 1-5 show that  TSS
actually decreased below the hatchery effluents (except below Rangen where
the stream Is entirely effluent).

The greatest effect of the trout hatcheries on Billingsley Creek TSS
levels will occur at the lowest flows.  To analyze the worst case Impact
of the proposed effluent limits on Billingsley Creek we assumed  all the
flow in the Creek was effluent from the trout hatcheries.  Further, we
assumed that all effluent discharge was at the Instantaneous maximum
permit levels at the same time.  The effluent flows used 1n the  analysis
are the mean flows given in Appendix Table A.

Table 2 lists the worst case conditions simulated and the expected
Billingsley Creek TSS concentrations below each hatchery.  The highest TSS
levels in the Creek during this hypothetical worst case would be below
Rangen (27.6 mg/1).

*Th1s high level  will  be  totally on  Rangen property and will occur over  a
stream reach roughly 150  meters long.

Even this worst case for  TSS  should  have little or no Impact on fish and
aquatic life.  According  to "Water Quality Criteria," (EPA, 1972) a maximum
suspended sediment concentration of  25.0 rag/1 provides a high level of
protection for aquatic communities while a maximum of 80.0 mg/1 provides a
moderate level of protection.  So even this worst case will provide a
relatively high level  of  protection.  The Idaho water quality standards
require that point sources not Increase the turbidity of receiving waters by
more than 5 NTU over background If background Is less than 50 MTU.  We do not
know what turbidity would result from the highest predicted TSS of 27.6  mg/1.
However, It can be estimated  roughly.  Table 3 below tabulates the highest
Instreara and effluent TSS levels and their corresponding turbidities.

Based on the data In Table  3,  It  appears  that  the turbidity resulting from
27.6 mg/1 TSS will  be about, or less  than,  5.0 NTU.   In light  of  the  fact
that 27.6 mg/1 is a fairly  conservative worst  case estimate of the  impact
of the hatcheries on Billingsley  Creek, we  feel  the permit Itnrits will  not
violate Idaho water quality standards or  adversely impact the  aquatic
community of Billingsley Creek.

Settleable Solids:
Composite samples were analyzed  for  settlcable solids from  the  Rangen
raceway and Jones settling pond  1n March.  Both samples were  0.1  ml/1.
JRB (1984) collected extensive data  on  settleable  solids at the Jones and
Rangen Raceways.   In 39 samples  from Rangen,  the TSS ranged from 14 mg/1
to less than 0.1  and the settleable  solids were all traces  (less than
O.T).  These data demonstrate that the  hatcheries  will comply with the 0.1
ml/I raceway effluent limit for  settleable solids  if they comply with the
suspended solids  limit.  In fact, these effluent limits will  result in
virtually no discharge of settleable solids from raceways.
                                  - 7 -

-------
Appendix Table F lists all of the TSS and settleable solids data  from JRB,
1984 for trout hatchery cleaning effluents.  In nine of the samples  the
TSS exceeded the 100 rag/1 effluent limits.  But of those nine,  only  two
exceeded the 1 ml/I settleable sol Ids limit.  In six of those nine,  only
"trace" settleable solids (less than 0.1 ml/1) were detectable.

The data In Table F, considered as a whole, Indicate that settleable
solids will generally be considerably lower than the effluent limits when
TSS 1s equal to the effluent limits.  However, the very limited data from
Rangen 1n Table 9 indicates that effluent settleable solids content  might
vary proportionally with TSS so that 100 mg/1 TSS would result  1n 1.0 ml/I
settleable solids.  Self monitoring data from Rangen (Appendix  Table G)
does not totally support this relationship.  It shows TSS levels  of  14.0,
38.0, 42.8, and 29.8 with corresponding settleable solids all less than
0.1 ml/I
                \
          v      • *
So, the Rangen Hatchery probably follows the trend apparent in  Appendix
Table F, i.e., settleable solids are less than the effluent limit of 1.0
ml/I when TSS equals the effluent limit of 100 mg/1.

Since TSS is the limiting parameter 1n the effluent limit, it appears that
the proposed limits will result 1n very little discharge of settleable
solIds to Billingsley Creek.  However, since settleable sol Ids  can
significantly impact the stream ecosystem, we simulated a hypothetical
worst case in.which the hatcheries all discharged their maximum allowed
limits of 0.1 ml/1  from raceway and 1.0 ml/1 from settling ponds.  We used
the mean effluent flows listed in Appendix Table A.

Table 4 gives the volume of settleable solids that would be discharged in
a day from each of the effluents 1n the worst case situation.   The average
settling velocity of the suspended sediments from Jones Hatchery  1s
1.57 cm/sec (JRB, 1984).  Billingsley Creek is generally from one to four
feet deep below the hatcheries so at a settling velocity of 1.57  cm/sec
the material will settle to the bottom between 30-78 seconds after
discharge.  At current velocities of-1-2 ft/sec, the material should
settle out between 30 and 156 feet from the outfalls.  After that, it
would probably be slowly distributed downstream as bed load.

The volumes listed in Table 4 are clearly unacceptable.  They, would  result
in large areas of stream being covered by the fish farm residues.  Though
these levels are possible under the proposed effluent limits, they are
highly unlikely for three reasons.  First, TSS is the limiting  parameter
in the effluent limitation.   If the TSS limits are met, settleable solids
will be quite low; probably present only as traces.  Second, the  effluent
data collected for this study and the JRB data show that the settling pond
discharges almost always discharge concentrations of TSS and settleable
solids much less than the permit levels.  Third, the higher concentrations
of TSS and settleable solids in the settling pond effluents will  only
occur during cleaning operations; usually a fraction of the day.

It 1s much more likely that virtually  no settleable sol Ids will be
discharged from the raceways.   This conclusion 1s based on the JRB  data
discussed above showing that settleable solids from the Jones and Rangen
raceways was always less than 0.1  ml/I  even  though TSS was as high  as  24
mg/1.  Further, the settling pond effluent loads  should be much less than
tabulated in Table 4.   According to JRB, at  Rangen, the large raceways are
cleaned every 30-6~0 days.  The small raceways  are cleaned everyday, but
cleaning effluents flow from each only 3-4 minutes.  Also 0.5 ml A  is  a
more likely, yet conservative estimate of the  level of settleable solids
discharged from Rangen.  Using that concentration and two hours cleaning

time each day, the daily load from Rangen is .48M3 or 17.2 feet3.   The
JRB report states that the. Jones settling pond does not, as  a rule,
discharge to the creek.  Therefore, much of  the time  it will deliver no
load to Billingsley Creek.

The daily load of settleable solids possible under the proposed effluent
limits is too great.  However, the hatcheries  are capable of maintaining
their settleable solids effluent concentrations much  lower than the permit
levels.  Most of the time settleable solids  are less  than quantifiable
detection limits in both the raceway and settling pond effluents.   These
"traces" of settleable solids do not adversely affect Billingsley Creek.
This excellent performance can be maintained at the hatcheries if an
emphasis is placed on  managing the solids load.  Therefore,  EPA and IDHW
should work with the hatcheries to develop management plans  and 0 4 M
plans that will facilitate maximum removal of  solids  from the effluent.

Nutrients-Nitrogen and Phosphorus:

Appendix Table H lists total nitrogen, total  phosphorus, and the
nitrogen/phosphorus ratios at Billingsley Creek.   Generally, both
nutrients are somewhat excessive, potentially  leading to nuisance growth
of aquatic vegetation.  This is confirmed by observations that Billingsley
Creek was characterized by dense growth of macrophytes and periphyton  in
1983 (JRB, 1984) and 1984 (Mike McMasters, Personal Communication).
Overall, phosphorus probably contributes more  to  the  vegetation problems
than nitrogen.  Total  phosphorus concentrations greater than .02 mg/1  can
                                   -  9  -

-------
lead to eutrophlc conditions In lakes.  Phosphorus was consistently near 1
mg/1 fn BHHngsley Creek.  The nitrogen/phosphorus ratio can be used to
estimate which nutrient 1s limiting plant growth.  A ratio greater than 15
Indicates that phosphorus 1s limiting algae growth.  A ratio lower than 15
Indicates nitrogen Is  limiting.   In BIlHngsley Creek the ratio 1s close
to 15 most of the time (Appendix  Table H).  This Indicates that nitrogen
as well as phosphorus  1s excessive and that reductions in either nutrient
should help lessen plan growth In the stream, especially perfphyton.  Many
of the rooted macrophytes can obtain nutrients from the substrate as well
as the water column.   Decreases 1n macrophyte growth will occur slowly.

 Table  E shows that the hatcheries contribute  nitrogen and phosphorus to B1
llingsley Creek.  JRB  (1984) and  McMasters (Personal Communication) both
found.vegetation to be denser below the hatcheries than elsewhere,
Indicating that the hatcheries contribute to plant growth. If at all
possible, nutrient loads, especially phosphorus from the hatcheries,
should be reduced.  Total phosphorus In the hatchery effluents ranged up
to 0.49 mg/1, high enough to be excessive In thfs effluent dominated
stream but low enough  to be difficult to remove.  Nitrogen, especially
nitrates and nitrites, are high 1n the effluents.  However, nitrates and
nitrites may be fairly high 1n the Influents to the hatcheries as well.
Station B1 Is at the headwaters of BIlHngsley Creek and may be indicative
of the quality of spring water in the valley.  Table I compares nutrients
levels at Station B1 and the effluents.  Total phosphorus, ammonia, and
Kjeldahl nitrogen are  all higher  in the effluent than at B1, but
nitrite/nitrate ts about the same in Bl as in the effluents.  So while the
hatcheries appear to contribute phosphorus, ammonia, and Kjeldahl nitrogen
to the stream, they may not contribute significant amounts of nitrate
which is the most readily used nutrient form of nitrogen.

High nutrient levels contribute to excessive plant growth in Billingsley
Creek.  The trout hatcheries contribute nutrients so effort should be made
to decrease effluent nutrient levels to the extent possible.  However
there is no evidence of serious degredation from the plant growth. Though
the plants cause depressions in dissolved oxygen levels at night, the
lowest recorded  levels (5.0 mg/1) are not dangerous to the aquatic
community. Further, the hatchery  effluent phosphorus concentrations are
extremely low. Therefore, EPA and IDHW should work closely with the
hatcheries to develop  management  and 0 & M plans that minimize the input
of nutrients to their  water supply and maximize the removal of nutrients
before discharging the water to Billingsley Creek.

UN-IONIZED AMMONIA

Un-ionized ammonia (NH3) data from Billingsley Creek are listed in
Appendix Tables D and  E.  Un-ionized ammonia was extremely low except on
May 22, 1984, at Station 3 when it reached 0.075 mg/1 and May 22, 1984, at
station 4 when it reach 0.0194 mg/1.  The state water quality standard for
NH3 is 0.02 mg/1 as a  30-day mean.  It appears from the data in Appendix
Table D that Billingsley Creek complies with that standard.
                                   -  10  -

-------
EPA has recently published draft criteria for NH3.  The criteria Include
a 30-day average value and a never to be exceeded value that varies as a
function of pH and temperature.  Appendix Table J lists the criteria for
BIlHngsley Creek using ambient pH and temperature data.  Note that the
BUllngsley Creek grab samples violated the 30-day average criterion only
once, on May 22, at station 83.  They never violated the maximum
criterion.

At their current discharge rates, the trout hatcheries are not causing
NH3 water quality standards violations.  Since the hatcheries discharged
right at or slightly less than their TSS limits, no NH3 problems are
expected from the proposed effluent limits.

DISSOLVED OXYGEN

Appendix Figures 1-5 show the dissolved oxygen (DO) concentrations
measured in BIlHngsley Creek.  00 was fairly high 1n the stream
throughout the study, with observed values never violating the state water
quality standard of 6.0 mg/1.

Starting 1n April much of the stream was supersaturated with DO when
sampled.  This is the result of dense vegetation producing DO during the
day.  DO saturation during the day is usually accompanied by depression of
DO levels at night.  IDHW monitored DO through a 24-hour period in July
(McMasters, Personal Communication).  On that day DO fluctuated
approximately 9 mg/1 from the highest daytime measurement to the lowest
nighttime measurement.  The lowest DO recorded that day was 5.0 mg/1.  The
high at that station was 13.2 mg/1.

Carbonaceous biochemical Oxygen demand (CBOD) ranged from 0.4-3.7 mg/1 in
the creek and 0.2-8.7 mg/1 1n the effluents.  These are very low levels of
BOD and would not be expected to affect DO concentrations in shallow fast
moving streams like Billingsley Creek.  This is confirmed by the DO data
discussed above.

In order to confirm that BOD from the hatcheries have little or no effect
on stream DO we utilized the stream water quality model to simulate DO in
the stream.  We checked model accuracy by simulating DO on the March and
June sampling dates.  Appendix Figures 6 and 7 compare simulated DO to
actually measured DO.  The model simulated actual DO levels quite well.
The underestimates in June are a result of plant caused supersaturation
discussed above.  The model does not simulate the effects of
photosynthesis on DO.  The model predicted average DO in the absence of
photosynthesis.  Photosynthesis can be accounted for by superimposing the
measured diurnal DO swing  (9.0 mg/1) on the model results.  This is done
by adding 4.5 mg/1 to the DO predictions and subtracting 4.5 from the
prediction.  The result is a daily DO swing from 4.5 mg/1 to 13.5 mg/1 in
the stream between Jones and Idaho Springs, very close to the measured
swing.  The model appears to be predicting instream time averaged DO
fairly well and can be used to predict DO in the worst case.
                                  -  11  -

-------
The worst case situation simulated assumed all the flow in the stream to
be effluent fro» the hatcheries.  The effluent flow rate for each hatchery
was set at half the June flow to reduce aeration rates and increase
residence t1«e 1n the stream.  The CBOO for all the dischargers was set at
the highest level recorded for any effluent during the study (9.0 mg/1).
Likewise, dissolved oxygen was set at the lowest level recorded for any
discharger (7.1 rag/1).

Appendix Figure 8 Illustrates the results of this worst case analysis.  DO
will not violate the water quality standard of 6.0 mg/1 as a result of BOD
and DO levels ,1n the effluents.  However, very low DO levels could result
from plant respiration if there 1s a 9.0 mg/1 dally swing in DO as
discussed above.  Utilizing the 9.0 mg/1 dally swing, the DO below Jones
could go down to 3.0 mg/1 under these worse case conditions.  This low DO
would last for a,short time because of the short detention time of water
In the stream.  It Is Important to note that average instream DO is never
lower than effluent DO in the worst case situation.  This shows that the
low DO 1s a result of the effluent level of 7.1 mg/1 that was assumed.
Reference back to Appendix Table E shows that most of the time effluent DO
was higher than 7.1.  Therefore, we feel that the worst case illustrated
in Figure 8 is a very conservative worst case.
