INTRODUCTION
This report presents an evaluation of waste treatment and waste
controls at the American Cyanamid Company's Santa Rosa Plant located
near Pensacola, Florida. The report specifically characterizes and
quantifies all plant discharges into receiving waters and evaluates
current waste treatment and waste control practices. The study, con-
ducted by the Environmental Protection Agency during March 6-12, 1972,
was in response to a recommendation of the third session of the Federal-
State Enforcement Conference on Escambia Bay.
Appreciation is extended to personnel of the Florida Department
of Pollution Control for assistance in making preliminary arrangements
and for providing laboratory space, and to American Cyanamid Plant
management and personnel for survey assistance.

HISTORY OF PROBLEM
PROBLEM SUMMARY
A water quality survey of the Escambia River and Bay was conducted
by the Federal Water Pollution Control Administration^ during September-
October 1969.(1) The Federal report stated that poor water quality con-
ditions in Escambia Bay and Mulat-Mulatto Bayou were caused by excessive
discharges of carbonaceous, nitrogenous, and phosphorous wastes from
local industrial sources, including American Cyanamld Company's Santa
Rosa Plant. The 1969 report attributed the following waste loads
(lbs/day) to American Cyanamld:
Phosphorus Nitrogen
8005 TOC Total Ortho TKN NH3-N NO2-NO3-N
4,450 5,230 3.0 2.0 4,160 538 693
FEDERAL-STATE ENFORCEMENT CONFERENCES
The first "Conference in the Hatter of Pollution of the Interstate
Waters of the Escambia River Basin (Alabama-Florida) and the Intrastate
Portions of the Escambia River Basin Within the State of Florida" was
held on January 21-22, 1970, at Gulf Breeze, Florida.
The conferees concluded that "the entire upper section of Escambia
Bay north of the Louisville and Nashville Railroad Company bridge is in
a state of accelerated eutrophication as shown by unstable dissolved
oxygen variations resulting from algal activity; high carbon, nitrogen
and phosphorus concentrations; and oxygen demanding sludge deposits."(2)
1/ Now the Environmental Protection Agency.
2
-------
The conferees further concluded that the Louisville and Nashville
Railroad bridge inhibited flushing and exchange between the upper and
lower bay, thus resulting in sludge deposits that cause water quality
degradation. The conferees also concluded that these conditions were
the result of waste discharges and circulation problems outlined in
the EPA report.
Recommendations of the 1970 conference affecting American Cyanamid
were that:
• Industries and municipalities reduce the carbonaceous
and nitrogenous wastes by 94 percent and the phosphorus
wastes by 90 percent by December 31, 1972.
• American Cyanamid immediately cease discharging acryloni-
trile.
The second session of the conference was held in Pensacola during
February 23-24, 1971. Previous conference recommendations were modified
by imposing effluent limits to augment the previously-established carbon,
nitrogen, and phosphorus percent reductions.(3) Load limits established
for American Cyanamid were:
• Biochemical Oxygen Demand (BOD5) - 425 lbs/day
• Total Nitrogen - 323 lbs/day
• Total Phosphorus - not applicable
The conferees recommended that these levels be met by December 31,
1972, and if these levels prove excessive, American Cyanamid must
develop a plan for completely removing their discharge from the bay.
3
-------
The company was also directed to submit, by February 15, 1972, a plan
foT maximum feasible reductions of carbonaceous material.
The third session of the Federal-State Conference was held in
Pensacola during January 24-25, 197 2. The conferees expressed dissatis-
faction with the inadequacy of American Cyanamid'a plans to meet con-
ference recommendations.(4) The conferees maintained the same percentage
reductions and effluent waste loads for carbonaceous, nitrogenous and
phosphorus materials established at the second session of the conference.
The time schedule required submission of plans for maximum reductions of
carbonaceous material by February 15, 1972, and reductions to meet con-
ference recommendations by December 31, 1972.
STATE OF FLORIDA ENFORCEMENT ACTIVITIES
In mid-1969, the Florida Pollution Control Board ordered American
Cyanamid to provide 90 percent minimum treatment to their wastewater
discharges. (5)
During March 1972, American Cyanamid was issued additional orders
for corrective action by the Florida Department of Pollution Control.
These orders required controls to prevent rainwater overflow of wastes
and submission of a report containing a preliminary plan of action for:
0 a sound in-plant source-control and wastewater management
program that will completely eliminate present discharges
of contaminated wastes into Escambia Bay.
• an abatement plan to provide, by January 1, 1973, not less
than 90 percent treatment far waatee to be disposed of by
4
-------
deep well injection (if applicable).
the elimination of liquid waste discharges, containing
contaminants, into Escambia Bay after December 31, 1972.
-------
FINDINGS
1. Wastewater discharges into Escambia Bay from American Cyanamid's
Santa Rosa Plant do not presently meet conference-established
limits. It is highly unlikely that the company will even come
close to meeting conference recommendations by December 31, 1972.
Since the 1970 Federal-State Enforcement Conference, the company
has apparently made substantial wastewater reduction through source
controls and process improvements; however, there have been no
improvements in or additions to the treatment facilities, and
effluent discharges continue to exceed by more than ten-fold the
allowable effluent limits set by the conferees in January 1971.
Recommended discharge limits and EPA study findings for the 1969
and 1972 studies are:
Recommended Loads 1969 Study 1972 Study
Parameter (lbs/day) (lbs/day) (lbs/day)
5-day Biochemical Oxygen
Demand (BOD5) 425 4,450 6,390
Total Nitrogen 323 4,850 3,850
Total Phosphorus Not Applicable 3 6
2. The major contaminants observed in the discharge into Escambia Bay
were the nitrogenous and carbonaceous materials. The final effluent,
some 10 to 12°C warmer than receiving waters, also contained sig-
nificant concentrations of total residue (average - 922 tng/1) and
thiocyanate (average - 52 mg/1). Trace amounts of metals and
6
-------
0.51 mg/l of 2,3-dibromo-propanol, an organic compound used as an
Intermediate in the manufacture of flame retardents, were also
detected in the effluent. Nitrogenous and carbonaceous wastes,
however, are the pollutants having the most detrimental effect on
water quality in the bay.
The discharge contained undetectable levels of acrylonitrile
In-plant modifications and increased efficiency of strippers had
increased the acrylonitrile removal by more than 99 percent.
Presently, 250 pounds per day of acrylonitrile are being landfilled.
3. The two 4-acre lagoon treatment system, designed primarily for the
removal of solids, was removing 72 percent of the non-filterable
residue, 8 percent of the BOD5, 37 percent of the total organic carbon
(TOC), 34 percent of the chemical oxygen demand (COD), and 22 per-
cent of the total nitrogen.
A. Fiber production during the 1972 study averages approximately 235,000
pounds per day. This represents a 8,000 pounds per day production
increase since the 1969 study. Maximum fiber production is projected
to increase to 416,000 pounds per day by 1975. At present production
levels, it may be possible to meet Federal-State Enforcement Conference
Recommendations with secondary biological treatment (including de-
nitrification) and associated in-plant modifications such aB
recycling of once-through waters, product recovery and process
improvements. At projected production levels, additional studies
will be needed to determine if conference recommendations can be
achieved by treatment techniques.
7
-------
Prior to 1970, no waste source controls were installed specifically
for pollution abatement. Since 1970, the removal and recovery of
acrylonitrile, sodium tbiocyanate and finish has resulted in sub-
stantial reductions in TOC, COD and acrylonitrile. Although acry-
lonitrile has been eliminated from the discharge into Escambia Bay,
the TOC load averaged 4,100 pounds per day — 1,130 pounds per day
less than the load in 1969. Approximately 6,000 pounds per day of
sodium thiocyanate has been removed from the waste stream. In-plant
changes scheduled for completion in 1972 should also substantially
reduce the volume of wastewater, the nonfilterable residue and total
carbon in the waste streams.
American Cyanamid refused to grant EPA permission to conduct inplant
sampling which restricted Federal wastewater sampling to lagoon
influent and effluent locations. The company did, however, conduct
concurrent sampling of the fibers area, reactor area, recovery area,
carpet plant, utilities area, and lagoon effluent. In-plant sampling
accounted for about 77 percent of the total carbon and 100 percent of
the total nitrogen measured by the company in the lagoon influent.
The reactor area contributed about 62 percent of the total carbon
and 78 percent of the total nitrogen in the lagoon influent.
American Cyanamid has drilled a 1,546-foot exploratory well to
evaluate the feasibility of subsurface wastewater disposal. Pre-
liminary wastewater management plans include the combined use of
biological treatment and deep well disposal to meet effluent
8

limits established by the State and Federal pollution control
agencies. The following data summarize the abatement program and
present projected waste loads for 1975.

NOTE: The existing EPA policy on the disposal of wastes by subsurface
injection states that:
"The Environmental Protection Agency is opposed to the disposal
or storage of wastes by subsurface injection, without strict
controls and a clear demonstration that such wastes will not
interfere with present or potential use of subsurface water
supplies, contaminate interconnected surface waters, or other-
wise damage the environment. Controlled subsurface injection
may be acceptable where: (1) It has been demonstrated to be
the best waste disposal alternative in terms of overall environ-
mental protection. Subsurface injection should be recognized
as an essentially temporary solution, subject to development
of better alternatives, and is to be minimized in its use for
the disposal or storage of wastes wherever possible, (2) It
is utilized in connection with overall planned management of
groundwater or related resources."
1/ Recycling accounts for the differences in wastewater volumes
generated and discharged.

TREATMENT ALTERNATIVES
ALTERNATIVES INVESTIGATED
American Cyanamid has investigated numerous proposals from both
the company Engineering and Construction Division, and Black, Crow and
Eidsness consulting engineers. These include:
• Ion exchange for thiocyanate recovery.
• Improved acrylonitrile stripper efficiency.
• Extended aeration.
• Aerated lagoon.
• Deep well disposal.
• Removal of DARCO fines from wastewater.
• New process techniques to reduce carbonaceous wastes.
• Water conservation and recycle.
RECOMMENDED ALTERNATIVES
After careful review of the company engineering reports and of
literature pertaining to American Cyanamidrs wastes, the following
are recommended:
• Clean water separation and recycling should be utilized
where possible.
• New process techniques should be incorporated when available,
• Additional consideration should be given to ion exchange
for thiocyanate recovery.
• With the removal of the DARCO/Hyflo solids, the installation
of ion exchange for thiocyanate removal, the recycling of
10
-------
dilute wastewater streams, and the biological treatability
of the wastes, the alternative of deep well disposal should
not be seriously considered at this time.
• One of the best available biological treatment alternatives
is aerated lagoons with a denitrification process.

DESCRIPTION OF PLANT FACILITIES
GENERAL
The Santa Rosa Plant of the American Cyanamid Company is located
In Santa Rosa County, Florida, on the eastern shore of Escambia Bay
(Figure 1). The plant area covers approximately 60 acres and includes
about 16 manufacturing and support buildings. The plant provides em-
ployment for approximately 640 people.
The principal product is acrylic fiber. Since the plant began
production in 1958, fiber production has increased to an average of
235,000 pounds per day. Facilities necessary to support maximum pro-
duction levels of 416,000 pounds per day of fiber have been installed
(Appendix D). The company anticipates maximum production in 1975.
The basic chemical manufacturing process is the production of
acrylic polymer from acrylonitrile and methyl-methacrylate monomers.
The monomers are reacted, washed, stored, and, when needed, dissolved
in sodium thiocyanate solvent. The dissolved polymer is passed through
spinnerettes which produce continuous fibers. The solvent is removed by
countercurrent washing of the fiber with water. Solvent recovery is
built into the manufacturing process, and more than 99 percent of the
solvent is recovered and reused. The fiber is then subjected to further
mechanical processes of crimping, cutting, and baling.
WASTE TREATMENT FACILITIES
The present wastewater treatment facilities at the Santa Rosa Plant
include a separate collection systems for storm waters, sanitary sewage
12
-------
FIGURE I
13
-------
and process wastewaters. Additions to the initial 1958 system were
installed in 1966. Plant area storm drainage is diverted into four
catch basins, where it percolates into the soil. Sanitary wastes are
treated through a primary system consisting of a manual bar screen and
two 12-foot by 8-foot Yoeman Brothers "Spirahoff" units, sludge drying
beds and chlorination.
The industrial waste facility was originally designed for a flow of
3.5 MGD. The facility, a single-celled lagoon, was designed for solids
removal, pH equilization and temperature control. The system was en-
larged by the addition of a second lagoon to accommodate a flow of
7.2 MGD.
Combined wastewater (including primary treated sanitary wastes)
enter the lagoon system through the chemical sewer; a splitter box
divides the flow approximately equally into each lagoon (Figure 2).
Each lagoon is about 4 acres in size; however, their capacities have
been reduced considerably by the disposition of solids. A baffle 90
feet long and stretching to the bottom was being installed in lagoon "A"
during the study. Lagoon "B" has a baffle consisting of 4-foot aluminum
sheets suspended from a pipe. The baffle system has been added to help
regulate pH fluctuations and to minimize short-circuiting of the water.
The inlet into lagoon "B" is equipped with a Parshall flume, flow
recorder, temperature recorder, and an automatic sampling device. The
outlets from both lagoons have an automatic pH recorder, temperature
recorder, an automatic sampler and a stainless steel screen for large
solids removal. Flow 1b measured by correlating the flow entering

lagoon "A" to that recorded at the influent of lagoon "B". The total
flow is measured by diverting all the flow into lagoon "B"; then split-
ting the flow to both lagoons and measuring the flow at lagoon "B".
The difference is the flow into lagoon "A".

AMERICAN CYANAMID WASTEWATER STUDIES
DISCUSSION OF PREVIOUS STUDY RESULTS
American Cyanamid initiated wastewater studies at the Santa Rosa
Plant in August 1969 by employing Black, Crow and Eidsness, Inc., as
consulting engineers. The firm's initial study, conducted during
September 1969, showed that existing treatment facilities were removing
37 percent of the COD, 7.8 percent of the thiocyanate, and 86 percent
of the suspended solids.(6) The firm recommended that the following
four-phase program be initiated to evaluate the treatment problem and
develop a realistic solution to this problem:
Phase I Wastewater characterization.
Phase II Evaluation of methods for reduction, treatment,
and disposal.
Phase III — Pilot plant studies.
Phase IV Design, engineering construction and startup.
Phases I, II, and III of the proposed studies have been completed.
The wastewater characterization studies were conducted in December
1969 and reported to the company in April 1970.(6)
Phase II studies were completed in October 1970. This study indi-
cated that the best overall removal of waste constituents could be
achieved by a combination of the following treatment processes:
• Source control
• Subsurface disposal
• Recovery of thiocyanate by ion exchange
• Biological treatment
17
-------
Bench-scale pilot plant studies were initiated in March 1971 on the
following biological treatment methods:
• Extended aeration
o Aerated lagoon
Studies also included wastewater recharacterization and deep well dis-
posal. Study results indicated that 90 to 95 percent of the BOD5
designated for biological treatment could be removed by either of these
methods and that effluent BOD5 loads would range from 450 to 850 pounds
per day. Total nitrogen removals by these methods were nil. Concen-
trated waste streams containing acrylonitrile from some process areas
were designated for deep well disposal.
Prior to 1970, numerous in-plant improvements were made to improve
the recovery of raw materials such as acrylonitrile and sodium thio-
cyanate. These improvements resulted in a 75 percent reduction in the
loss of sodium thiocyanate for each pound of polymer produced (Appendix D).
No waste source controls were installed specifically for pollution abate-
ment prior to 1970. Since January 1970, wastewater reductions have
resulted from the following source controls and process improvements:
• Removal of acrylonitrile-contaminated water from the
chemical sewer has reduced the AN, COD, and T0C by 1,089,
22,630, and 1,569 pounds per day, respectively;
• Increased efficiency of strippers has resulted in more
than a 99 percent removal of acrylonitrile and an
additional reduction of approximately 700 pounds per day;
• Removal and recovery of sodium thiocyanate from the
18
-------
chemical sewer has resulted in the removal of approximately
6,000 pounds per day, and
• Finish material removal from the chemical sewer has reduced
total carbon by approximately 500 pounds per day.
Planned in-plant changes and their estimated effect on the pollution
abatement program are:
• Removal of DARCO/Hyflo solids — 70 percent reduction in
suspended solids (operational date, September 1972);
• Clean water separation and recycle — 20 percent reduction
in flow (operational date, fourth quarter 1972), and
• New process for polymer production — 3,000 pounds per day
total carbon reduction (operational date, fourth quarter
1972).
WASTEWATER MANAGEMENT FLAN
Although average daily fiber production at the Santa Rosa Plant is
presently 235,000 pounds, production is planned to increase from the
present maximum daily level of 264,000 pounds to a maximum daily level
of 416,000 pounds in 1975 (Appendix D). Virtually all facilities needed
to support the 1975 levels of production have been installed at the plant.
Treatment facilities will be designed to handle 1975 projected waste
loads. Waste loads generated or discharged to treatment facilities at
the present base and projected levels of fiber production ares

DISCUSSION OF STUDY RESULTS
STUDY PROGRAM
Initially, study objectives were to characterize and quantify all
plant wastewater discharged into receiving waters; evaluate current
waste treatment and waste control practices, and propose alternatives
for best available treatment technology for waste abatement. However,
company officials objected to in-plant sampling by EPA and Federal
wastewater sampling was restricted to lagoon influent and effluent
locations. Although the company conducted sampling of the fibers area,
reactor area, recovery area, carpet plant, utilities area and lagoon
influent concurrently with the EPA sampling period, in-plant information
was not sufficient to permit a detailed evaluation of waste treatment
and control practices and hampered the successful completion of study
objectives.
To obtain data representative of normal plant operation, sampling
conducted by EPA started on March 7, 1972, and continued for five
consecutive days. Samples were collected from the following designated
locations:
• AC-1 — Influent to Lagoon "B"
• AC-2 — Effluent from Lagoon "B"
• AC-3 — Effluent from Lagoon "A"
• AC-4 — Source wells (5)
Twenty-four hourly composite samples were collected by the use of
automatic samplers at Stations AC-1, AC-2, and AC-3. These samples were
analyzed for BOD5, TOC, COD, nitrogen series (TKN, NH3, NO2-NO3),
21
-------
total phosphorus, residue (total, dissolved, nonfilterable, non-
filterable volatile, volatile dissolved) acidity and alkalinity. Grab
samples were also collected at these locations and analyzed for phenols,
oil and grease, cyanide and thiocyanate. Daily composite samples col-
lected at Stations AC-2 and AC-3 were composited over five days for
organic and metal analysis. Composite samples of water supply wells
(Station AC-4) were collected twice during the survey and analyzed for
the previously-listed parameters except for BOD5, cyanide, phenolics and
oil and grease. All samples were split with the company for quality
control purposes.
Daily analysis for BOD5, alkalinity and acidity were performed by
EPA field personnel located at the Gulf Breeze Laboratory of the Florida
Department of Pollution Control. All other analyses were performed at
the Region IV, SAD Laboratory in Athens, Georgia. Samples were air
shipped daily to Athens.
DISCUSSION OF ANALYTICAL DIFFERENCES
There was considerable difference in some of the parameters analyzed
by the EPA and American Cyanamid laboratories. The greatest differences
were in the nitrite-nitrate (NO2-NO3) analysis. Generally, EPA nitrite-
nitrate results were about 4 to 5 times higher than company results. Al-
though the laboratories used different analytical methods (EPA used the
automated cadmium reduction method while American Cyanamid used the zinc
reduction method), the different procedures would not account for the
differences recorded. An investigation into the cause for the analytical
22
-------
difference revealed that both laboratories experienced difficulties in
analyzing this parameter.
DISCUSSION OF AMERICAN CYANAMID SAMPLING RESULTS
In-plant sampling conducted by American Cyanamid was primarily to
show the contributions of carbon and nitrogen from process areas. Results
of the 5 days of sampling are shown in Table I and presented in Figure 3.
The sampling locations accounted for all of the total nitrogen
waste loads generated and about 77 percent of the total carbon discharg-
ing into the lagoon system. Approximately 62 percent of the total
carbon and 78 percent of the total nitrogen in the lagoon influent comes
from the reactor area. The carpet plant and utilities areas are minor
contributors of carbon and nitrogen to the treatment system.
DISCUSSION OF EPA WASTE SAMPLING RESULTS
A comparison of study results with results from the 1969 EPA study
show very little progress in reducing the waste load discharged into
Escambia Bay (Table II). Although American Cyanamid has apparently
taade substantial reductions through source control and process improve-
ments since 1969, there have been no improvements in or additions to the
treatment facilities, and effluent discharges continue to exceed by a
factor greater than ten the allowable effluent limits established at the
January 1971 session of the Federal-State Enforcement Conference. To
some degree, production increases have minimized the results of pollution
abatement efforts. Fiber production, averaging about 235,000 pounds per
day during the study period, has increased by 8,000 pounds per day since

the 1969 study. Influent and effluent loadings shown in Table III
indicates the ineffectiveness of existing treatment facilities.
Acrylonitrile has been removed from the wastewater system and is
presently being landfilled at a rate of 250 pounds per day. Study
results revealed undetectable levels of acrylonitrile in the effluent.
The acrylonitrile being landfilled was not observed and the success
of this method of disposal is unknown.
The daily plant discharge contained 6,390 pounds of BOD5 — 1,940
pounds per day greater than the load measured during the 1969 study.
One explanation for the increase in the BOD5 is the removal of acrylo-
nitrile from the waste stream. Acrylonitrile is inhibitory to the BOD
test and the removal of this material has provided more reliable BOD5
data. There was insufficient dissolved oxygen depletion for positive
results in 2 of the 5 BOD^ determinations. Although the average in-
fluent BOD5 153 mg/1 was 29 mg/1 lower than company results, there
was reasonably good agreement with effluent concentrations, Effluent
BOD5 concentrations are assumed to be representative of average values
since they agree with monthly values reported by the company to the FDPC
between October 1971 and February 1972 (Table IV).
The BOD5 removal efficiency of the ponds was very low. Lagoon "A"
was only removing about 5 percent of the influent BOD5, while reductions
in lagoon "B" were about 10 percent. Although solids had been removed from
lagoon "A" in early 1969, a considerable amount of deposition has taken
place which drastically affected retention time in the lagoon and con-
sequently affected BOD5 removal. Solids are scheduled to be removed from

both lagoons during May 1972; however, it is doubtful that this will
significantly affect the BOD5 removal efficiency of the lagoons.
One of the most significant series of parameters to be examined in
relation to water quality in Escambia Bay are those of total Kjeldahl
nitrogen (TKN), ammonia nitrogen (NH3-N) and nitrite-nitrate nitrogen
(NO2-NO3-N). An average total nitrogen loading of 4,930 pounds per day
was measured in the influent with an average of 3,850 pounds per day
being discharged into Escambia Bay. The overall reduction was 17 and 27
percent for Lagoon "A" and "B", respectively. The data show a mean total
nitrogen reduction of 22 percent. The nitrogen loadings (lbs/day) and
removal efficiencies are shown below:

The influent TKN and NO2-NO3-N values changed very little from day
to day, but ammonia values did vary from a minimum of 1.75 mg/l to a
maximum of 15.0 mg/l, averaging 6.16 mg/l. During the study, ammonia
and organic nitrogen averaged very close to those values reported to the
FDPC by American Cyanamid, but the nitrate-nitrite values found by EPA were
substantially higher than those reported by American Cyanamid (Table III).
The nitrogen data reported by American Cyanamid to FDPC and those analyzed
by their laboratory on samples divided with EPA showed reasonably good
30
-------
agreement except for NO2-NO3-N, which were some 4 to 5 times lower than
those values reported by EPA. This difference amounts to nearly 1,000
pounds per day more nitrogen than is being reported by the company.
Examination of the nitrogen data shows that both lagoons are an-
aerobic. Since there is an overall mean removal of 46 percent for nitrates
and 157 percent increase in ammonia nitrogen, a healthy population of
nitrogen-reducing bacteria must be present. The process follows a non-
typical denitrification path of nitrates being reduced to nitrites with
further reduction to both ammonia and nitrogen gas.
Phosphorus levels found in the effluent wastestreams were low
both lagoon discharges averaged 0.14 mg/1. The loadings of phosphorus
3 pounds per day observed during the 1970 EPA study were comparable to
the 6 pounds per day loading measured during the 1972 study.
Chemical Oxygen Demand (COD) on a pounds per day basis was averag-
ing 23,200 entering the lagoons and 15,200 leaving the lagoons. The
reduction was 31 and 38 percent for lagoons "A" and "B", respectively.
The reactor areas of the plant accounts for about 62 percent of the COD.
(6) There was close agreement between the COD values reported to the
FDPC by American Cyanamid and those found during the study. The COD
values were relatively constant during the study.
Daily effluent TOC values fluctuated only slightly from a maximum
of 92 mg/1 and a low of 83 mg/1 and averaged 88 mg/1. Influent total
organic carbon (TOC) loads averaged 6,500 pounds per day while effluent
loads averaged A,100 pounds per day. The daily discharge contained
1,130 pounds less TOC than the average discharged in 1969. The TOC
31
-------
removal efficiency is 37 percent. TOC values were slightly lower than
those reported by American Cyanamid to the FDPC, but a portion of this
difference is due to the the inorganic carbon included in the total
carbon (Table IV)•
The heated wastewater entering the lagoons was dark. The influent
water temperature averaged 41.6°C (106.9F) but was reduced to an average
of 25.6°C and 27.1°C in "B" and "A" lagoon effluents, respectively.
The effluent temperature is approximately 10 to 12 C warmer than either
the surface intake water or other effluents measured during the survey
period.
Total residue loads from the production areas were relatively constant
with an average of 48,000 pounds per day in the lagoon influent. Tre
ment facilities, designed primarily for the removal of suspended solids,
removed 72 and 68 percent of the nonfilterable fixed and volatile residue,
respectively. Only 13 percent of the total residue, of which 96 perc
is dissolved, was removed by the lagoons. The daily discharge into
Escambia Bay contained 41,600 pounds of total residue, 1,020 pounds
nonfilterable residue and 740 pounds of nonfilterable volatile residu
Table V contains a detailed examination of residue loadings and removal
eff ic iencies.
Cyanide was found in the effluents of both lagoons. There was an
increase in the cyanide concentrations in each lagoon. Influent valu
ranged from a minimum of 0.1 mg/1 to a maximum of 0.5 mg/1, averaging
0.28 mg/1. Effluent concentrations averaged 0.36 and 0.44 mg/1 from
lagoons "A" and "B", respectively. Effluent loading, based on grab

sample values and daily average discharges, averaged 18 pounds per
day. Lagoon "B" had an increase of 10 pounds per day or a 57 percent
increase as compared to "A", which had an increase of 8 pounds per day or
a 29 percent increase. The cyanide values observed during the survey
were lower than those reported to the FDPC by American Cyanamid (Table III).
The cyanide concentrations in the influent were relatively constant. The
increase in effluent concentrations was probably due to the cyanide being
sorbed and released by the solids in lagoons. Influent thiocyanate con-
centrations were very erratic, ranging from 16.3 to 94.0 mg/1, with a
mean of 34.1 mg/1. Thiocyanate influent loadings averaged 1,540 pounds
per day, with effluent loadings averaging 2,350 pounds per day. The
increase in thiocyanates noted in the effluent is probably due to the
variability of concentrations entering the lagoons and/or the solids
holding and releasing thiocyanate to the system. The values reported to
the FDPC by American Cyanamid over the six months prior to the EPA study
showed good agreement with the 1972 study values.
A scan of a five-day composite sample from the lagoon effluents
(Stations AC-2 and AC-3) was made to determine the presence of metals.
Significant concentrations of metals detected by the scan were verified
by atomic absorption methods. Only trace amounts of a few metals were
observed (Appendix C). The most significant metal in the discharge was
5.0 pounds per day of chromium.
An organic scan, using a gas chromatograph-mass spectrometer
system, was made on methylene chloride extracted sampled from effluent
sampling stations AC-2 and AC-3. The only compound found with a sizable
34
-------
peak was 2,3-dibromo-propanol. This compound, an intermediate in the
manufacture of flame retardants, was detected in the sample from Station
AC-2 at a concentration of 0.51 mg/1. The environmental effects, if any,
of this compound are unknown.
In conjunction with the wastewater analyses, samples were collected
from the company's five wells and composited. Analyses of this water
shows that the source water is of high quality and uncontaminated.
A dye study was performed to help determine the degree of short
circuiting through both lagoons. The results show that Lagoon "A" has
a greatly-reduced retention time with poor mixing. The peak of the dye
started through the effluent after two hours and dropped off after three
hours (Figure 4) . Lagoon "B" was stable with good mixing and peaked
after 21 hours. These results verified reports from company personnel
that they had experienced problems with Lagoon "A" in controlling pH
due to poor mixing and short circuiting.

PROCEDURE FOR ORGANIC ANALYSES
Samples collected from Stations AC-2 and AC-3 were approximately
neutral pH when received. They were extracted with 15% methylene chloride
in hexane, made strongly basic with KOH and re-extracted with 15%
methylene chloride in hexane, acidified with sulfuric acid and
extracted for the third time with methylene chloride. The samples
were dried by passing through glass wool and then concentrated to
1 ml in a Kuderna-Danish concentrator. The acid extract was esterified
using diazomethane. All extracts were injected into a gas chromatograph
equipped with a flame ionization detector. The column was glass
6'x2.5 mm I.D. packed with 3% SE-30 on Chromosorb W, HP. The oven
was programmed from 7 5°-240° @ 10°/min. Any peaks detected were subjected
to further analysis with the Finnigan GC/MS Model 1015 system. The com-
pounds listed were confirmed by injecting a known standard into the
GC/MS. Quantitation was done on the gas chromatograph.
All samples were extracted in duplicate and the concentrations
found represent the average of the duplicates. Concentrations found
should be considered minimum concentrations as the percent recovery of
each compound from water is unknown.

2, Letter 3/9/72, Mr. G. J. Kenngott to Mr. Charles Sweatt
Dear Mr. Sweatt,
This is to confirm our telephone conversation of Tuesday, April 11, 1972
concerning in-plant carbon and nitrogen measurements made during your
recent survey of the Santa Rosa Plant, March 7th to March 12th, and to
transmit this data to you.
The attachment is a summary of flow and carbonaceous and nitrogenous
waste loadings from the Fibers, Reactor and Recovery Areas and the lagoon
influent. Ihese areas accounted for an average of about 777. of the total
carbon, about 101% of total nitrogen and about 68% of total flow, when
compared to the same parameters measured on lagoon influent.
Below the above summary is the Carpet Plant and Utilities Areas
contribution to carbonaceous and nitrogenous waste for one 24-hour
period. This data and prior characterization studies have indicated
these two wastewaters as insignificant sources of carbonaceous and
nitrogenous wastes.
As you plan to be in our area on April 20, 1972, we would suggest that we
meet at 1300-1330 hours to review the attached and the lagoon data. We
would appreciate an advance copy of your analytical results on the lagoon
so that we may be prepared to comment and reduce time requirements for the
meeting. Review of these data should satisfy requirements of objectives
1 and 2 enumerated in reference 1. We would also like to discuss objective
3 (ref. 1) at this meeting, since there is limited time prior to your report
to the Conferees on May 1, 1972.
We hope the attached data end the meeting time and subject will meet with
your approval.
Sincerely yours,
X.7U'

Dear Mr. Adams:
As requested in our meeting of April 20, 1972, we are providing the
base load information (Attachment I) and a summary of source controls
and process improvements completed since January 1970, or in progress,
to reduce the base load to Santa Rosa's wastewater treatment facilities
(Attachment II).
"Base load" is defined as contaminants contributed by plant opera-
tions to our wastewater treatment system.
Column 1 - is the base load of the lagoon influent in January 1970.
Column 2 - is the base load of lagoon influent as measured in 1970
but corrected for anticipated plant capacity in 1975*
(We believe the 1975 base load is pertinent to the pres-
ent consideration because we intend to design facilities
to handle that load. It has been Cyanamid's plan to reach
the 1975 level of production as evidenced as far back as
1966 when the second lagoon was designed and installed
with a capacity to handle the 1975 production level. In
addition, virtually all facilities needed to support the
1975 level of production have been installed at this plant.)
Column 3 - is actual influent load March 7 thru 12, 1972.
Column 4 - is the data in Column 3 recalculated to the same production
rate as shown in Column 1.
Column 5 - shows effect of process improvements and source controls
completed since 1970, i.e., Column 1 less Column U.

Mr. Billy H. Adams -2- May 9, 1972
The Santa Rosa Plant was designed, and operates to recycle costly
raw materials such as acrylonitrile and sodium thiocyanate. Prior to
197^ numerous in-plant improvements were made to improve the recovery
of these materials; for example, recovery of sodium thiocyanate improved
so that loss per pound of polymer decreased "by about 75$ •
