I. Introduction
The Rappahannock River Basin is located in northeastern Virginia and
is bounded by the Potomac-Shenandoah River Basin on the north and west, and
by the York River Basin to the south. The river flows in a southeasterly
direction from its headwaters in the eastern slopes of the Blue Ridge Mountains
to the Chesapeake Bay. Tidal effects extend a distance of about 110 miles
from the Chesapeake Bay to the "fall line", in the vicinity of Fredericksburg.
Serious water quality problems have been experienced in the Rappahannock
River just downstream of Fredericksburg, Virginia. At low fresh water flows,
organic wastesaccumulate in the estuary creating degraded conditions. Dissolved
oxygen concentrations have approached zero, fish kills have been reported, and
during these periods the River becomes generally undesirable for most uses.
The State of Virginia's dissolved oxygen stream standard of 5.0 mg/1 as a daily
average and a minimum of 4.0 mg/1 is frequently violated over a ten-mile stretch
of the Rappahannock River just below Fredericksburg.
In 1969-1970 the Federal Water Pollution Control Administration- (FWPCA)
participated with local, state, and other Federal agencies in a joint water
resources study of the Rappahannock River. At this time a need was found for
a mathematical model of the river to be used as a planning tool for predicting
the water quality responses of the river to various combinations of waste loads,
flows, etc. An intratidal single-stage biochemical oxygen demand (BOD) -
dissolved oxygen (DO) model was developed by the FWPCA to meet this need.
I/ The Federal Water Pollution Control Administration in April 1970 was
changed to the Federal Water Quality Administration and in December 1970
was changed to the Environmental Protection Agency
-------
Subsequently, in an effort to better represent the complex processes
which determine the DO of the river, the AUTOSS water quality model was
applied to the Rappahannock River. AUTOSS is a steady-state mathematical
model which can be used to predict average water quality conditions at mean
tide (variations within a tidal cycle cannot be obtained with this model).
In addition to carbonaceous and nitrogenous BOD, benthic demand and net oxygen
production by algae are considered. For complete documentation of AUTOSS,
see EPA Technical Report 54, AUTO-QUAL Modelling System, by R.L. Grim and
N.L. Lovelace(l). The major improvement in this modelling work over the
previous work was that additional significant parameters such as nitrogenous
BOD were modelled and a more extensive data base was used.
The passage of PL 92-500 in October 1972 required under Section 303(d)(l)(A)
that each state shall identify those waters in which the minimum treatment
requirements of Section 301(b)(l) (secondary treatment for municipalities and
best practicable treatment (BPT) for industries) are not stringent enough to
meet the water quality stardards. Such areas are termed "water quality limited
segments". The Rappahannock River in the Fredericksubrg, Virginia, area is
classified as a water quality limited segment due to the low DO concentrations
frequently observed. Therefore, according to Section 303(d)(l)(C) each state
has the responsibility to establish waste load allocations for the water quality
limited segments which will meet water quality standards. These waste load
allocations are subject to EPA approval. Since EPA had an existing water
quality model of the Rappahannock River which considers both carbonaceous and
and nitrogenous BOD, technical assistance was provided to the State in developing
the waste load allocations for this stream segment. The close working
-------
relationship between the State Water Control Board and the EPA staff facilitated
development of the waste load allocations which are presented in a latter
section of this report.
In addition,the Virginia Institute of Marine Science (VIMS) had developed
* mathematical models for the prediction of salinity and dissolved oxygen in
the Rappahannock River. These are described in the VIMS report, "Studies of
the Distribution of Salinity and Dissolved Oxygen in the Upper Tidal Rappahannock
River", dated June 1972(2). The DO model developed by VIMS explicitly
considers the tidal behavior of the estuary in the advection term of the mass
balance equations. This approach differs from the one taken with the EPA model
where only the net non-tidal velocity component is included, with tidal mixing
being simulated with the dispersion term. Both approaches are theoretically
sound and proven methods of simulating estuarine behavior.
As originally developed, the VIMS model considered only carbonaceous BOD
(calculated from measured 5 day BOD's using a conversion factor of 1.5). Based
on data collected by EPA, it was shown that a significant part of the DO problem
in the Rappahannock was due to nitrogenous BOD, which had not been considered
with the VIMS model. For this reason, the EPA model (which considers
nitrogenous BOD) was used in making the wasteload allocations for the Rappahnnock
*' River. Subsequently, as the result of discussions between VIMS and EPA, VIMS
modified their model to include nitrogenous BOD, as well as bethic demand and
i -
the net production of oxygen by photosynthesis. In making comparative runs
with the two models, it was found that the minimum average DO predicted with
both models agreed to within 0.01 mg/1.

II. MODEL VERIFICATION

II. Model Verification
A. Availability of Water Quality Data
Extensive field data had been collected during the summer of 1970
by both EPA and VIMS. The FMC Corporation also collected a limited number
of samples of the Rappahannock River. All three sources of data were used
in the calibration and verification process.
The EPA data is presented in its entirety in Appendix D. Sampling
station descriptions are given in Table 1. All samples were collected at low
water slack. It should be noted that the BOD,, values listed in Appendix D-l
are not necessarily the actual values measured by the lab, but are the values
taken from the first order, single-stage BOD curve which was fitted to the
actual long-term BOD data. The ultimate biochemical oxygen demand (BOD )
shown was determined from this curve and includes both carbonaceous and nitro-
genous BOD. The corresponding k.. rate that is shown is a single-stage bottle
rate only, and should be used as such. A complete listing of all the actual
long-term BOD determinations for each sample is shown in Appendix D-2. The
listing is the output from the computer program used to curve fit the BOD data
which used either a least squares fit or Lee's Graphical Analysis adapted
for the computer. The station number of each sample is listed in the upper
left-hand corner (disregard the last two digits of the number, which are lab
identification numbers only).

B. River Mile Index
In order to avoid confusion, both statute river mila and its associated
landmark are listed in Table 1. Care must be exercised when comparing
different sources of data, since the river mile of a particular location
is likely to differ. This was found to be the case with the Rappahannock
River, therefore, the landmarks should be used when cross-referencing data
or results.
C. Hydrologic Data
The TTSGS maintains a streamflow gaging station (number 01668000) approxi-
mately 4 miles above the City of Fredericksburg. The drainage area at this
station is 1596 square miles. There is approximately 40 square miles of
unpaged drainage area between this gage and river mile 104.3, which is just
downstream of the recently constructed Massaponax Sewage Treatment Plant, the
most downstream point source discharge in the water quality limited segment.
Since all but 2% of the drainage area is gaged, the freshwater inflow to
the estuary is accurately determined from the USGS gage near Fredericksburg.
The daily hydrograph for this gage during the months of May through August 1970
is shown in Figure 1. Also noted are the days on which a complete set of
stream samples (includes nitrogen data) were collected by EPA for use in
calibrating and verifying the EPA water quality model. It can be seen from
the hydrograph that the samples collected on July 13, July 22, and August 5
are not of much value in calibrating a steady-state model due to wide fluctua-
tions in the flow regime.

D. Cross-Section Data
Cross-sectional data was developed from the nautical chart of the
Rappahannock River (605-SC, Edition 10, January 1974) published by the
U.S. Department of Commerce. From these cross-sections, average widths
and depths at mean tide were calculated for use in the model. See listing
of input data for the model in Appendix A-l.
E. Salinity Model Verification and Determination of Dispersion
Coefficient
The dispersion coefficients can be evaluated for a particular net advec-
tive flow from the observed salinity profiles. Data collection by VIMS was
used to verify the model for salinity from River Mile 0.0 (mouth) to River
Mile 110.3 (fall line). Plots of the verification profiles are shown in
Appendix B-l. As can be seen from the verification profiles, the river is
essentially fresh water above Mile 70. This obviously eliminates the use ut
salinity as a tracer to determine the dispersion coefficients in this area.
Therefore, the dispersion coefficients determined from the salinity profiles
at the most upstream point (Mile 60.0) was used through the fresh water
segment to the fall line.
The dispersion coefficients that were determined are shown in the
complete input data listing for the salinity verification (Appendix A-l).
In the continuing process of updating and further refining existing mathe-
matical models, consideration should be given to conducting dye studies of
this fresh water area of the Rappahannock River in order to more precisely
determine the dispersion coefficients. Also, the possible variation of the
-------
12
dispersion coefficient with fresh water inflow should be investigated
especially at extremely low flows. This variable relationship between
dispersion and flow was shown to exist by Clark and Feigner (3) in the
Potomac Estuary and by Paulson (4) in the Delaware Estuary.
F. Dissolved Oxygen Model
The T)0 model was verified from the fall line (River Mile 110.3) to
•River Mile R5.0 using four simulation periods during the summer of 1970.
VIMS, EPA, aid the FMC Corporation had independently sampled the Rappahannock
^iver during this time, which provided an excellent data base with which
to work. The verification profiles are shown in Appendix B-2. The specific
details of the verification runs are discussed in the following sections.
1. Tidal Velocities and Reaeration
Tidal velocity measurements were obtained by VIMS during July
and August 1970. From these current velocity measurements, the average
tidal velocity at various locations along the Rappahannock River was determined
from:
V = V X 0.637
avg max
where
V = average tidal velocity
avg
V = maximum tidal velocity
max

This relationship assumes a sine curve distribution of velocity through-
out a tidal cycle. (See listing of Input Data, Appendix A-2). The average
tidal velocities are used in determining the reaeration rate (k2) which is
calculated internally within the model by the O'Connor-Dobbins formulation:
k. (base e) = 12.9 V °'5
2 avg
D ""
where:
k~ = reaeration rate (I/day)
V = average tidal velocity (ft/sec)
avg
D = average river depth (ft)
2. Benthic Oxygen Demand
The benthic oxygen demand was determined in the field by EPA at
two locations, using the benthic respirometer technique (Table 2). Values
slightly less than the actual measured values were found to work best in
the calibration and verification runs (see Input Data List, Appendix A-2).
3. Net Oxygen Production by Algae
The net oxygen production by algae is equal to the difference between
the oxygen produced during photosynthesis and the oxygen utilized by respira-
tion. The method used to estimate the net oxygen production follows the
method presented by Dominic M. DiToro at Manhattan College's 17th Summer
Institute in Water Pollution Control (5). The technique basically follows
that outlined by Ryther (6) in 1956 and Ryther and Yentsch (7) (1957), with
the emphasis shifted from primary production to dissolved oxygen production.
-------
15
The light saturrted rate of oxygen production, P , has been correlated
s
with the concentration of chlorophyll''a' (a measure of the algae population
density):
P =0.25 Chi
s a
where
P = mg 09 produced/1/day
3 £•
chl = chlorophyll 'a' concentration in ug/1
Si
Using the average value of 40 ug/1 chlorophyll *a' that was observed during
the EPA sampling survey, the light saturated rate of 02 production is:
P - (0.25) (40) = 10.0 tng 0,,/1/day
s /
The ratio of the average rate of 0« production, Pav, to the maximum rate, P ,
is given by:
Pav f (2.718) f * ° (Vl } -(Ia/Is)
P * T H k S e S/-e
s el
where
H * average depth of the well mixed layer
T *= time period over which the 0_ production is being
averaged (i.e., 1 day)
f «= fraction of time period that is daylight
I « light intensity saturation value
I * mean daily light intensity
a.
k - light extinction coefficient
a
-------
16
For the Rappahannock River the following values were used:
H = 10.1 ft. (represents average depth from
river mile 90 to river mile 95)
T = 0.583 day (14 hrs)
I = 2000 ft-candles
a
I = 2000 ft-candles
s
K = .7/ft (this corresponds to a secchi disk depth
of approximately 2.7 ft)
therefore:
Pav „ ,,
since
P ~ 10.0 mg 09/l/day
S *-
Pav * (0.14)(10.0) = 1.4 mg 02/l/day
The respiration of algae must also be accounted for in order to determine
the net effect. The respiration rate, R, has also been correlated to the
chlorophyll 'a' concentration.
R - 0.025chl
a
where
R = mg 0_ utilized/1/day
Chi = chlorophyll 'a1 concentration ug/1
3,
therefore for the Rappahannock River,
R = (0.025)(40.0) = 1.0 mg 02/l/day
The net oxygen produced by algae is then the difference between production
and respiration.
Net 0? production = Pav - R
= 1.4 - 1.0
= 0.4 mg 0 /I/day
-------
17
2
For use in the model, this number must be converted to grams CL/m /day.
Using the average depth of 10.1 feet and the completely mixed assumption,
0.4 mg 02/1/ day x 3012 1/m2 x 1.0 Bm/1000 mg
= 1.2 gm 02/m2/day
It should be remembered that this method yields an approximate answer
to a very complex biochemical phenomenon, and is therefore subject to
some degree of uncertainty. It did, however, appear to work well in the
2
verification runs. A value of l.Ogm 0»/m /day was used at river mile 102.0,
2
increasing linearly to 1.3 gm 0 /m /day at river mile 90.0. Above river mile
103.0 the net oxygen produced is zero, due to the relatively low population
density of algae.
4. Determination of Nitrogenous BOD and It's Decay Rate
The oxygen demand of nitrogenous materials is referred to as the
nitrogenous BOD. More specifically this involves a series of consecutive
reactions in which organic nitrogen is converted to ammonia which is oxidized
through nitrite to nitrate. The hydrolysis of the organic nitrogen (urea,
amines, proteins) to ammonia does not utilize oxygen. The subsequent
oxidation of the ammonia is a two step process, involving two distinct auto-
trophic groups of organisms. The ammonia oxidation is accomplished by the
genus Nitrosomonas and the conversion of nitrite to nitrate is carried out
by the genus Nitrobacter.
The oxidation of ammonia by Nitrosomonas is given by the following
equation: (8)
NH + 3/2 02 >• HNO_ + H20
The oxidation of nitrite by Nitrobacter is shown by:
HN0 + 0 »•
-------
18
Considering the entire nitrification reaction, we have:
14 64 62
1 4.57
Thus, from the stoichiometric relationship of oxygen to ammonia, 1 mg/1
of ammonia is equivalent to 4.57 mg/1 of nitrogenous BOD. However, since
organic nitrogen is converted to ammonia, it also is included in the nitro-
genous BOT). Therefore, the nitrogenous BOD is determined by the total
kjeldahl nitrogen (TKN) , which includes both organic and ammonia nitrogen,
multiplied by 4.57.
Although nitrification actually involves a series of sequential reactions,
it can be represented in terms of nitrogenous BOD using a single overall
reaction. This approach was used in the EPA model of the Rappahannock River.
The decay rate for nitrogenous BOD was found to be 0.10 (base e) from river
mile 108.6 to river mile 98.0, then decreasing linearly to 0.05 at river
mile 90.0.
5. Determination of Ultimate Carbonaceous and It's Decay Rate
Two methods were used to determine the ultimate carbonaceous BOD at
each sampling station. The first method uses the "traditional" or "normal"
ratio of 1.5 to 1.0 between ultimate carbonaceous and 5 day BOD in converting
the measured BOD,, values to the ultimate carbonaceous BOD. The applicability
of this ratio to stream BOD samples is always somewhat questionable. However,
the results calculated by using the ratio of 1.5 to 1.0 agree rather well with
the results obtained using an alternate method of obtaining the ultimate
carbonaceous BOD.
-------
19
The second method of obtaining the ultimate carbonaceous BOD makes
use of the long-term BOD results (shown in Appendix D-2). The BOD's
were incubated for 20 to 30 days in most cases. The BOD that is measured
at any time actually represents the total BOD, which includes both the
nitrogenous and carbonaceous portions. Therefore, to determine the
carbonaceous BOD at any time, one must subtract the nitrogenous portion
from the total BOD. For each sample the ultimate carbonaceous BOD was
determined by subtracting the ultimate nitrogenous BOD from the total
BOD measured at maximum incubation time for that particular sample. The
ultimate nitrogenous BOD is obtained from the measured initial value of
total kjeldahl nitrogen (TKN), multiplied by 4.57.
Having obtained the ultimate carbonaceous BOD of each sample, the
river decay rate of carbonaceous BOD can be determined from the observed
concentrations as one proceeds downstream. A rate of 0.15 (base "e") was
determined at river mile 108.6, which decreases to 0.06 (base "e") at river
mile 90.0. The rate is a maximum in the vicinity of the waste discharges
from the City of Fredericksburg's sewage treatment plant and the FMC Corpora-
tion. The decrease in decay rate as one proceeds downstream from a waste
input that is observed on the Rappahannock River has been found to occur
on numerous other rivers and streams by this writer and has been reported
by O'Connor(5) and others. The possible explanation for this decline in
the rate of decay is that the more readily oxidizable carbonaceous substances
are utilized first by the heterotrophic bacteria, leaving progressively more
stable, biologically resistant materials as one proceeds in the downstream
direction.
-------
20
6. Waste Loads Used for Dissolved Oxygen Model Verification
During the simulation periods chosen for verification, there were
onlv two significant dischargers affecting the dissolved oxygen balance
of the upper Rappahannock estuary (river mile 110.3-85.0). They are (a)
the City of Fredericksburg and (b) the FMC Corporation.
(a) City of Fredericksburg
Effluent data was collected and analyzed by State Water Control
Board personnel during the summer of 1970 (see Table 3). The average
BOD,, discharged during that period was 734 Ibs/day. Using a ratio of
1.5 between ultimate carbonaceous BOD and 5-day BOD, the average ultimate
carbonaceous BOD was calculated to be 1100 Ibs/day. A ratio of 1.5 is
representative of a "typical" municipal waste and was used since there was
no other data available for the Fredericksburg sewage treatment plant.
Since effluent data for oxidizable nitrogen was not available during
the summer of 1970, an estimated concentration of 20.0 mg/1 TKN was used.
TTrLs value was decided upon after reviewing effluent data collected in 1973
and 1974 by the state and EPA. (See Tables 4 & 5). Using the stoichio-
metric oxygen equivalent of TKN conversion to nitrate-nitrogen, the nitro-
genous oxygen demand was calculated to be 91.4 mg/1 or 1750 Ibs/day at an
average flow of 2.30 mgd.
The average waste load shown below was used for all four simulations
for the City of Fredericksburg:
net flow 2.30 mgd
ultimate carbonaceous BOD 1100 Ibs/day
nitrogenous BOD 1750 Ibs/day

(b) FMC Corporation
Monthly Waste and River Reports are submitted by the FMC Corporation
to the State Water Control Board (Appendix C-l). Daily effluent flows,
suspended solids, and 5 day BOD concentrations are reported for the
industrial waste treatment plant. Nitrogen data is not reported.
Evaluation of this data indicates that FMC's discharge is highly variable,
with frequent high BOD and suspended solids concentrations. In subsequent
discussions with Mr. Ernest G. Ladd, Environmental Coordinator, FMC Corp.,
it was mentioned that the Fredericksburg plant did not have sludge disposal
facilities and, therefore, sludge is wasted to the Rappahannock River in
the treatment plant's effluent. Evidence of this is shown by the high
BOD and suspended solids concentration which periodically occur in the
effluent. In addition to the process effluent, the cooling water discharge
is also a source of carbonaceous BOD due to leakage through the barometric
condenser system. Nitrogenous BOD is essentially not present, as indicated
by their permit application and a limited number of EPA samples. Monitoring
of the cooling water intake and discharge for BODS is not routinely performed
and, therefore, the contribution from this source cannot be accurately deter-
mined. The permit application indicates a net load of 436 Ibs/day BODS while
the limited number of EPA samples range from 406 Ibs/day to 916 Ibs/day BODS.
The lack of comprehensive effluent data, plus the variability of FMC's
effluent quality, made it difficult to determine either the carbonaceous
or nitrogenous BOD being discharged. When the reported effluent BODS is
converted to ultimate carbonaceous BOD by a ratio of 1.75 to 1.0 (see
Appendix C-2 for discussion of ratio) and various simulations were run,
it became evident that this loading was too small to produce the observed
carbonaceous and BOD dissolved oxygen values found downstream of the FMC plant.

(b) FMC Corporation
Monthly Waste and River Reports are submitted by the FMC Corporation
to the State Water Control Board (Appendix C-l). Daily effluent flows,
suspended solids, and 5 day BOD concentrations are reported for the
industrial waste treatment plant. Nitrogen data is not reported.
Evaluation of this data indicates that FMC's discharge is highly variable,
with frequent high BOD and suspended solids concentrations. In subsequent
discussions with Mr. Ernest G. Ladd, Environmental Coordinator, FMC Corp.,
it was mentioned that the Fredericksburg plant did not have sludge disposal
facilities and, therefore, sludge is wasted to the Rappahannock River in
the treatment plant's effluent. Evidence of this is shown by the high
BOD and suspended solids concentration which periodically occur in the
effluent. In addition to the process effluent, the cooling water discharge
is also a source of carbonaceous BOD due to leakage through the barometric
condenser system. Nitrogenous BOD is essentially not present, as indicated
by their permit application and a limited number of EPA samples. Monitoring
of the cooling water intake and discharge for BODS is not routinely performed
and, therefore, the contribution from this source cannot be accurately deter-
mined. The permit application indicates a net load of 436 Ibs/day BODS while
the limited number of EPA samples range from 406 Ibs/day to 916 Ibs/day BODS.
The lack of comprehensive effluent data, plus the variability of FMC's
effluent quality, made it difficult to determine either the carbonaceous
or nitrogenous BOD being discharged. When the reported effluent BODS is
converted to ultimate carbonaceous BOD by a ratio of 1.75 to 1.0 (see
Appendix C-2 for discussion of ratio) and various simulations were run,
it became evident that this loading was too small to produce the observed
carbonaceous and BOD dissolved oxygen values found downstream of the FMC plant.
-------
25
However, since the river samples collected by EPA indicate a consistent,
definite increase in both carbonaceous and nitrogenous BOD in the immediate
vicinity of the Fredericksburg sewage treatment plant and the FMC Corp.,
the FMC waste load could be determined from the observed river concentrations.
Since fairly good effluent data was available for the City of
Fredericksburg's sewage treatment plant, their discharge for the four
simulations was assumed to be the constant average value previously discussed.
The additional waste load needed to match the observed increase in river loads
was assumed to come from the FMC Corp. The following loads for the FMC Corp.
were used in calibrating and verifying the dissolved oxygen model. It
should be noted that FMC does not add any net flow to the Rappahannock River,
since it withdraws its process water from and returns it to the river.
June 22, 1970 Simulation
net ultimate carbonaceous BOD 14,900 Ibs/day
net nitrogenous BOD 14,250 Ibs/day
note: FMC discharge records indicate high BODS and suspended
solids concentrations June 16 through June 18, which are
reflected in the observed river concentration.
June 29. 1970 Simulation

net nitrogenous BOD 8,750 Ibs/day

note: nitrogenous BOD estimated from observed river concentrations,
Carbonaceous BOD obtained from average of August 26 and 27
reported loading for the industrial waste treatment plant
plus 436 Ibs/day BODS for the cooling water discharge
(average value obtained from the permit application) .

III. Conclusions and Wasteload Allocation
Using EPA's verified dissolved oxygen model of the upper tidal Rappahannock
River, various pollution abatement alternatives were evaluated. At the 7-day,
10-year low flow, the minimum treatment required by section 301(b)(l)(A) and (B) of
PL 92-500 (BPT and secondary treatment) proved to be inadequate. The predicted
minimum daily average dissolved oxygen concentration under minimum treatment
conditions is 2.3 mg/1, with eight consecutive miles of river violating the
daily average dissolved oxygen standard of 5.0 mg/1.
To achieve the dissolved oxygen standard for the Rappahannock River, treat-
ment more stringent than secondary and "best practicable treatment" must be pro-
vided by both the municipalities and the industry that discharge to the river.
The allowable wasteloads were determined and allocated between the dischargers
according to the following procedure.
The design conditions used in making the allocations are:
streamflow - 43 cfs at fall line (7-day, 10-year low flow of 42 cfs at
the Fredericksburg USGS gaging station.
temperature -29 C determined statistically from data taken at the
Fredericksburg USGS gaging station and represents the
maximum mean monthly temperature plus two standard deviations.
boundary conditions at fall line -
dissolved oxygen - 7.8 mg/1
NBOD - 1.25 mg/1
CBOD - 1.45 mg/1
benthic demand - for all allocations runs, the benthic demand was assumed
to be 1.0 gm oxygen/square meter/day throughout the upper
reaches of the Rappahannock (RM 99-110). It is felt that
the high benthic demand that had been measured in 1970 and
used in verifying the model was due primarily to the dis-
charge of waste sludge from the FMC waste treatment plant.
-------
29
The planned elimination of this practice by FMC should result in a decreased
benthic demand in this area of the river. Just how much the benthic demand
will decrease cannot precisely be predicted, although a reasonable conserva-
tive value to be expected would be 1.0 gm oxygen/square meter/day (normal
range of estuarine muds is 1.0 - 2.0 gm oxygen/square meter/day)(9).
All other model parameters are identical to those found from the
verification runs.
Im making the allocations, the following waste sources and their future
planned design capacities were considered.
Waste Source River Mile Design Capacity
Fredericksburg Sewage Treatment Plant 108.5 4.6
FMC Corporation 108.1 7.42
Proposed Massaponax Sewage Treatment Plant 105.1 6.0
It should be noted that the existing South Stafford Sewage Treatment
Plant was not included in the waste load allocations. This plant is an
interim facility scheduled to be phased out in 1978, with the sewage going
to the Massaponax treatment plant.
Through discussions with Va. State Water Control Board, Bureau of Applied
Technology personnel, it was decided that in making the waste load allocations,
the FMC Corporation would provide treatment equivalent to the best available
technology economically achievable" (BAT) as defined by EPA regulations
promulgated April 5, 1974. This level of treatment is needed because of the
severe D.O. problem in the Rappahannock River. The BAT treatment level for
the FMC Corp. limits the monthly average discharge of BODS to 1260 Ibs/day.
To attain this limitation, the source of BODS (barometric condensers) entering
the cooling water should be eliminated. This would leave the industrial
-------
30
waste treatment plant as the only source of nitrogenous and carbonaceous
BOD. Since this treatment plant is already achieving an average discharge
of 11.13 Ibs/day of BODS, the allocated BODS is based on this number.
Nitrogenous BOD was not limited in the regulations defining BAT. However,
since the nitrogenous BOD is an important factor in the dissolved oxygen
balance of the Rappahannock, a limitation of 185 Ibs/day TKN (3.0 mg/1 net
TKN) was imposed. This value is the reported existing discharge from the
FMC waste treatment plant.
With the above load for FMC and the municipal waste treatment plants
at secondary treatment (see criteria in Table 5), it was determined that
the dissolved oxygen standard of 5.0 mg/1 as a minimum daily average for
the Rappahannock River would still be violated. Equal percentage reductions of
both carbonaceous and nitrogenous BOD were applied to the municipal facilities
until the minimum dissolved oxygen stream standard was attained. Table 6
shows the allocated loads to meet a minimum daily average DO of 5.0 mg/1
at the 7-day, 10-year low flow.

RATIO BETWEEN ULTIMATE CARBONACEOUS

-------
-------
RATIO BETWEEN ULTIMATE CARBONACEOUS AND 5-DAY BOD
FOR THE PIC CO_RP.
Data supplied by the FMC Corporation shows that the BOD,, is 60%
of the BOD_n. (See following letter dated January 21, 1974).
Since the normal waste consists mainly of carbonaceous material,
it is appropriate to use the first order BOD-tii^e equation to detcrraine
the ultimate carbonaceous BOD.
where
L = BOD exerted in tine "t"
L = ultimate BOD
K = BOD reaction rate
then
'
.
therefore
T ' -5k
L,_ = 1-e
since
, -20k
L20 1-e
I, = .60
then
.60 = l-e~5k
, -20k
1-e
solving by a trial and error technique
k = .17
substituting back into the BOD-time equation,
and
L
_! = 1-75

RETURN RECEIPT REQUESTED

Philadelphia, Pa. 19106
Attention: Walter F. Lee: x
Gentlemen:
This is in response to your January 16 telephone call requesting
information as to the relationship between BOD^ and BODu at our
•^ .Fredericksburg, Virginia plant.
The plant has provided me with the following data:
PPM BOD5 %
DATES NO. BOD5 BOD2Q OF BOD20
Late 1972, Jan. 1971* 19 8l 138 59
Feb. - July, 1973 17 85 lUl 60
The above data confirms my recollection that the plant's untreated
wastewaters are nearly as degradable as the standard BOD curve de-
veloped for municipal wastes. There are no data for longer than
20 days at present.
Please let me know if you require additional information.
Sincerely,
Ernest C. Ladd
Environmental Coordinator
