INTRODUCTION
This report contains an evaluation of waste treatment at Container
Corporation of America's (CCA) Integrated Pulp and Paper Mill located
at 3rewton, Alabama. The two-week study, conducted during June-July 1971
by the Environmental Protection Agency (EPA), was prompted by 1970
enforcement action. The study was designed to determine the volume of
carbonaceous waste generated by increased production, evaluate treatment
efficiency and qualify any relative changes in water quality in the
Conecuh-Escambia River below CCA's discharge.'
This i.-? the third Federal report containing data relative to
carbonaceous waste discharges from Container Corporation's Brewton
mill. The first study was conducted during September-October 1969
in response to a request from the Governor of Florida to the Federal
Water Pollution Control Administration"'' Southeast Region for technical
assistance in evaluating interstate and intrastate pollution in Escambia
River aiid Bay. Results of the study were contained in a report entitled
Effect of Pollution on Water Quality, Escambia River and Bay, Florida
and served as Federal evidence of pollution in a January 1970 enforce-
ment conference called to consider the matter of pollution of interstate
and intrastate water in Escanih I a River and Bay. The report identified
Container Corporation's Brewton Mill as the major point source of
carbonaceous wastes discharged into the Conecuh-Escambia River from
waste sources In Alabama. Conference recommendation Included the
removal of 90 percent of the carbonaceous waste generated at t':u-
1/ Now the Environmental Protection Agency.

Brewton Mill. At a February 1971 reconvened conference, following
a detailed study (August 1970) of vaste loads before and after treatment,
the conferees recommended that CCA's daily discharge be limited to 4,850
pounds of 5-day Biochemical Oxygen Demand (BODj). This progress report
contains the status of survey finding with regard to conference recommen-
dations and compares study results urith previous findings.
The cooperation and contribution of Container Corporation's mill
management during the study are gratefully appreciated. Particular
acknowledgements are due to personnel of the mill's Technical Engineering

SUMMARY
Container Corporation of America's integrated pulp and paper mill
at Brewton, Alabama has increased average mill production from 900 to
addition of a 22-acre aeration basin housing ten-75 horsepower aerators.
With the addition of the aeration basin, treatment units in operation
at the time of the June 1971 survey included a clarifier, liquid oxygen
applicator, oxidation pond, and ponding in six natural lakes. Time
of travel for the 17.2 million gallons per day (MGD) of unbleached
pulp processing waste routed through this complex of treatment units
was approximately 4.8 days. Bleaehery waste and woodyard drainage
amounting to some 17.3 MCD receive t re aimer.through "he- systoir. of
natural lakes only. The success of the pollution abatement program
initiated by CCA is clearLy demonstrated by the following comparison
of results from the August 19?0 and June 1971 studies:
1,050 tons per day. Accompanying this increased production was the

CONCLUSIONS
1. Additional secondary units placed in operation by Container
Corporation hnve resulted in BOD5 reductions in excess of the
90 percent recommended by the conferees at the February 1971
Escambia River-Bay Enforcement Conference.
2. Through the implementation of additional secondary treatment
and improved in-plant controls^ Container Corporation has reduced
the discharged effluent to less than half the 4,850 pounds per day
limit established by conference recommendations.
3. Container Corporation has not complied with the conference
recommendation that bleach plant and woodyard wastes be provided
secondary treatment.
4. All waste loadings measured at the Brewcon Mill were reduced as
a result of additional pollutiun abatement.
5. Woodyard wastes arc the largest source of non-ti1terable
suspended and volatile solids discharged to the system of natural
lakes.
6. Seventy percent of the color in the wastes flowing into the
system of natural lakes are the result of bleach plant discharges.
7. Although corrective measures: have improved treatment efficiency
and drastically r. >.i>- -.i . en, .id-.lii ici.il reductions
can be achieved by:
• Providing additional treatment to bleach plant and
woodyard wastes;
• Eliminating short circuiting in the aeration basin and
I
oxidation pond.
-------

8. Although Container Corporation has not directed treatment toward
color reduction, color in the effluent was less intense than that
observed in previous surveys and there was not a noticeable change
in color in the Conecuh River above and below the point of CCA's
discharge.
9. Except for naturally occurring low pH value? in study area
tributaries (Murder, Franklin Mill, Little Escambia and Big
Escranbia Creeks) and elevated BOD^ in Big Escambia Creek,
parameters measured indicated that water in Conec-.ih-Escjmbia River
tributaries were of relatively good quality.
-------
STUDY AREA
CONTAINER CORPORATION OF AMERICA
Container Corporation of America's mill at Brewton, Alabama, is
located in the Conecuh-Escambia River drainage basin (Figure 1). The
Integrated Kra£t pulp and paper mill processes an average of 1,050 tons
per day of pulp, of which 900 tons per day are from wood chips and the
remainder bought paper for recycling. Approximately half of the pulp
produced is bleached. Expansion plans include increasing wood chip
pulping capacity to 1,050 pounds per day in March 1972.
Waste treatment facilities consist of a clarifier, liquid oxygen
applicator, aeration basin, oxidation pond and Franklin Mill Creek
plus swamp and natural system of 6 lokes. The aeration basin was placed
in operation during October 1970; however, operational difficulty
delayed continuous operation until January 1971. Figure 2 contains a
schematic of waste treatment plus supplimentary information about
each treatment unit.
All wastes do not receive the same degree of treatment. Unbleached
pulp process wastes are routed through the entire treatment system;
however, bleach plant n;.d woodyard wastes are conveyed via Franklin Mill
Creek to the swamp and natural lake systen.. Mill sanitary was'.es are
routed into the clarifier and serve as the only source of nutrients to
the treatment system. Mill wastes are discharged into the Conecuh
River at a point approximately 2.7 miles above the Alabara-riorida i: ?.:e
line.
Color removal is presently being investigated; however, no additional

treatment improvements are scheduled for any phase'of Container's treatment
facility. •
CONECUH-ESCAMBIA RIVER BASIN
The Conecuh-Escambia River rides near Union Springs, Alabama, and •
i ;
terminates its south-southwestward journey in Escambia Bay at Pensacola,
Florida. The total drainage area of the Conecuh-Escambia River Basin is
4,132 square fniles. Thr: Conecuh River and its tributaries in Alabama
drain an area of approximately 3,817 square miles.
I
Streams within the basin flow through wooded areas, are generally
shallow with relatively swift currents, and contain the usual natural
debris found in waters traversing wooded lands. Major tributaries to
the Conecuh-Escambia River in the vicinity of the study area include
1 v
Murder, Little Escambia, and Big Escambtia Creeks. The- Conecuh River
serves as a source of process water for Container Corporation. Other
direct uses of the river and its tributaries, excluding fish and wild-
life uses, are for waste disposal. Murder.Creek receives industrial
wastes from T. R. Miller Company and treated and untreated municipal
wastes from Brewton and East hrewton, respectively. Big Escambia Creek
also receives effluent from t.ho waste stabilization pond at Flomaton,
Alabama. Little Escambia Creek traverses the Pollard Oil Field; however,
previous studies have show:', the water is of relatively good quality.
Escambia Bay, the recipient of wastes discharged into the Conecuh-
Escambia River Basin, has .i continuous record of massive fish kills.
Although many factors which cause water quality degradation in the bay
have been documented, other contributing causes and the triggering
-------
I
mechanism are still questionable am*. are undergoing investigation. The
study of waste discharges into teceiving waters of the Conecuh-Escambia
I
drainage system and water quality in these surface waters near the
* f
Alabama-Florida state line are a portion of the ongoing investigations.
-------
WATER QUALITY STANDARDS
Since the Conecuh-Escambia River originates in Alabama and termi-
nates in Florida, it is classified as an interstate stream. Study area
tributaries—Big Escambia and Little Escambia Creeks--are also interstate
streams by the same definition. Murder Creek, the other major tribu-
tary in the immediate study area, is an intrastate stream since it
originates and terminates in Alabama.
The Conecuh-Escambia River is classified for recreation anf/or
t
fish and wildlife uses. Figure 3 shows the Conecuh-Escambia River use
classifications established by Alabama and Florida. In the Alabama
portion of the study area, the Conecuh River, Big Escambia Creek,
Little Escambia Creek and Murder Creek are classified for fish and
wildlife uses. In the Florida portion of the study area, the Escambia
River, Big Escambia Creek and Little Escambia Creek are classified as
Class III waters, waters suitable for recreation and the propagation
and management of fish and wildlife.
Specific criteria originally adopted by the Alabama Water Improve-
ment Commission has not been accepted by EPA and is presently being
revised. The State of Florida has also been notified by EPA that their
criteria are no longer acceptable and that revisions will be required.
However, the r.ow criteria requirements hn.ve not been i'inalized. Table I
contains specific water quality criteria presently adopted by -.he two
states which pertain, t.o the two use classifications.

Study Program-
At the second session of the February 1971 Escambia' Bay Enforce-
ment Conference, recommendations required Container Corpqration to
reduce its BODj by 90 percent and established a Jzaximua effluent waste
load of A,850 pounds per day. Also included in the reconxnendation was
» /
an evaluation of increased pulping capacity on BOD5 discharges.
An evaluation of Container Corporation's waste abatement facility
and the relative effect of the waste discharge upon water quality in
the Conecuh-Escambia River was conducted during the weeks of June 20
'and 27, 1971. The mill survey was designed to determine the volume of
wastes generated by Increased product production and to determine the
effectiveness of the improvement in treatment following the addition of
a 22-acre aeration basin after the August 1970 field study. Eight
influent and effluent sampling sites located at each treatment unit were
sampled to determine treatment effect on BODj, TOC, COD, color, solids,
pH and temperature. Stream samples wftre collected from 7 sampling
locations within the immediate basin area and analysed for parameters
that would reflect any relative changes in water quality below the
mill discharge. Both ln-plant and strou^ sampling locations are shown
i
in Table II. Other chemical sampling included sampling of the oxidation
pond for dissolved oxygen fluctations >'ud bleachery waste for polychlori-
nated biphenols (PCB's) content:.
Dye tracer studies were conducted to demonstrate time of travel
throughout the entire treatment system. -Jater quality data was supple-
mented by flow measurements at both in-plant and stream sampling stations.

STUDY FINDINGS
GENERAL DISCUSSION
Climatologic conditions within the Brewton area were seasonal and
almost constant. Average high teaperatures were 95.9°F, 2 degrees above
normal."^ Precipitation was almost nil within the Brewton area except
for a few scattered showers the latter part of the second week. Flows
in Murder Creek and the Conecuh-Escambia River showed increases the
' i
second week from precipitation north of Brewton.
The Escambia River at Century, Florida has a drainage area of
3,817 square miles and a 37-year average daily discharge of 5,952 cubic
feet per second (cfs) with extremes from 596 cfs to 77,200 cfs. The
seven-day, 10-year low flow is 785 cfs. The-U.'S. Geological Survey
gaging station at Century, Florida reports the average flow in the
Escambia River at Century for the two-week study period was 2,560 cfs.
Little Escambia, Franklin Mill and Murder Creeks were gaged and
referenced with tape downs to establish rating curves. Big Escambia
Creek was not gaged because of water depth. Existing flumes and weirs
were used for in-plant flow measurements at sampling stations CC-1,
CC-5, CC-6, and CC-7. The discharge at station CC-8 was formulated
from water treatment plant us.Tgtt records. The flow at Station CC-2
was calibrated and continuously measured with Stevens recorders. The
Brewton Lake discharge (CC-4) was stream gaged and assumed to be constant
because of physical conditions.

CONTAINER CORPORATION'S TREATMENT EVALUATION
Comparison of 1970 and 1971 Study Results
With the addition of a 22-acre aeration basin, the average BOD5
removal efficiency of the treatment system at the Brewton Mill improved
from 81 percent to 92 percent.^ Corresponding TOC reductions showed
no significant improvement — 69 percent removal for 1970 compared to 70
percent removal this year. The TOC analyses added to the 1971 study
indicated an overall removal rate of 80 percent. Color tn the effluent
was 85 units lower than that observed during the 1970 survey. The
step reduction in these parameters through the treatment system are
summarized in Table III, and Table IV contains a summary of waste treat-
raent loads. All water quality data are presented in Appendix E.
Physical and Chemical Data
During the study period, the volume of waste in the mill effluent
was 34.5 million gallons per day (MGD). Waste flow from the bleach
plant averaged 15.3 MGD and pulp processing waste averaged 17.2 MGD.
The flow from the woodyard operation, including water plant filter
r
backwash wastes, average approximately 2 MGD. Although not a product
of mill operation, an average flow of approximatley 1.6 MGD in Franklin
Mill Creek flows through the swamp and natural lake system. Figure 2
contains average flow:: observed throughout the treatment system and
depicts the efl'ects of seepage and evaporation on the treatment system.
1J All comparisons are between CCA field studies of August 1970 and
June 1971.

Although average production was 150 tons per day higher than last
year's 900 tons per day, the average untreated BODj load generated
decreased from 44,500 pounds per day to 28,200 pounds per day. Reduction
by ln-plant controls*coupled with a treatment reduction of 92 percent^
produced an average effluent BODj of 2,220 pounds per day or a discharge
equivalent to that from a human population of 13,100 A BODj reduc-
tion of 25 and 83 percent were noted in the pulp process waste routed
through the clarifier and aeration basin, respectively. The average
BOD^ load in the oxidation pond effluent shoved a discharge of 1,310
pounds per day, an overall reduction of 93 percent. Average BOD^
reductions throughout the treatment system are shown in figure 4.
The untreated T0C load generated by the mill was down from last
year's 67,500 pounds per day to 50,500 pounds per day. Neither this
reduction nor the addition of the aeration basin noticeably affect the
TOC removal rate. An average TOC load of 15,200 pounds per day was
discharged to the Conecuh River (Figure 5). This represents a 5,600
pound per day decrease from 1970. It should be noted that only the
pulp wastes are conveyed to the aeration basin, whereas the bleach
plant wastes are discharged untreated to the system of natural lakes.
The average daily TOC discharge from the bleach plant is 19,900 pounds.
Results from the 1970 study showed that the TOC in the pulp processing
wastes received an 84 percent reduction in the clarifier and oxidation
pond. With the addition of the aeration basin to this treatment, the
TOC reduction was 83 percent.
Brewton Mill BOD/TOC regression analyses expressed as percent
1/ One population equivalent ¦ 0.17 pounds per capita per day.

BOD removed showed approximately a 1 to 1 removal rate for TOC as a
function of BOD between the 25 percent to 75 percent removal range.
These were computed from the August 1970 data. Above 75 percent
removal, the inherent differences in TOC and BOD are very relevant and
no relationship is seemingly available. For example', at Brewton Lake
discharge, after approximately 5 days retention, the B0D/T0C regression
line shows a constant slope which indicates no change in TOC for
varying BOD concentrations. This same relationship was apparent with
the addition of the aeration basin.
Although the 1970 study did not include a COD analysis, samples
collected during the 1971 study showed that the daily waste generated
contained 205,500 pounds of COD. The daily effluent from pulp processing,
bleach plant and woodvard contained 153,000, 47,100, and 5,440 pounds
of COty respectively. The overall COD reduction through the treatment
system was 80 percent. The COD reduction through the aeration basin and
oxidation pond were 84 percent and 89 percent, respectively. The system
of natural lakes removes about 29 percent of the COD in the influent;
however, the daily discharge Into the Conecuh River still contains
40,100 pounds. Figure 6 shows the average COD reduction throughout
the treatment system.
The non-filterable suspended solids removal at the Brewton Mill
was 93 percent. The average daily discharge to the Conecuh River
contained 4,860 pounds of suspended solids, a 10,270 pound per day
reduction over the 1970 load. The raw pulp process wastes at t'v clar-
ifier inlet are the largest source of suspended solids at 45,800 pounds
per day. The suspended solids load in the effluent from the clarifier
was 12,600 pound per day, a removal of 72 percent. Treatment through
the aeration basin and oxidation pond results in a overall reduction
-------
FIGURE 6
-------
16 o-s
of 88 percent. The oxidation pond effluent contained a suspended
solids load of 5,760 pounds per day. The daily oxidation pond effl-
uent contains 1,580 pounds more of suspended solids than the aeration
basin effluent. Plankton-algal growth and a seasonal increase in
insect larvae and insects probably account for this increased load.
The 9,640 pounds per day of suspended solids from the woodyard and
filter plant backwash are the largest single source of solids discharged
to the system of natural lakes. Prior removal of these solids would
appreciably reduce the suspended solids load discharged to the Conecuh
River. Bleach plant waste contained only 3,320 pound of suspended
solids. Figure 7 illustrates the average suspended solids load for
each sampling site in the treatment process.
The mill discharge to the Conecuh River contains 2,730 pounds per
day of non-filterable volatile solids. This load represents a 92
percent reduction in the total volatile, solids produced from the three
waste sources. The daily discharge from pulp processing, bleach
plant and woodyard operation contained 29,300, 2,300 and 2,830 pounds
of volitable solids, respectively. Average volatile solids in the
v
pulp processing waste was reduced to 1,250 pound per day, a 96 percent
reduction, by treatment through the man-made system. Average volatile
solids loads for each sampling site are contained in Table III.
There is no direct method for removing color employed at the Brewton
Mill. Figure 8 illustrates the color concentrations at each in-plant
sampling station. There was a slight increase in color as the wastes
flowed through the system of natural lakes. At the Franklin Mill Creek
sampling site (C(>3), where all wastes have mixed, the color was 299
units, of which 70 percent was from the untreated bleach plant wastes.
The average color concentration in the discharge to the Conecuh River
-------

was 325 units.
Samples collected from the bleach plant at Brewton Lake were
analyzed for polychlorinated biphenols (PCB's); however, PCB's were
not detected in the effluent.
Special Studies
A diurnal study to show dissolved oxygen fluctuations in the 140-
acre oxidation pond was performed June 23 and 24. Figure 9 exhibits
the extremely high dissolved oxygen concentrations in the shallow
pond. A large plankton-algal population existed which produced dis-
solved oxygen concentrations in the pond effluent near or above the
saturation point at all times. Dissolved oxygen in surface samples
varied from 2.8 to 18.0 mg/1, while dissolved oxygen in bottom samples
ranged from 3.0 to 12.0 mg/1.
Dye studies were used to demonstrate the retention time of pulp
process wastes in the aeration basin and oxidation pond and the time
of travel of wastes through the swamp and natural system of lakes. Time
of travel studies of the flow of bleach plant wastes to the junction of
other wastes were also made.
Dye study procedures are included in Appendix B. The dye studies
showed approximate travel times of:
• 26 minutes from the oxygen application nozzle to the aeration
basin inlet;
• 6 hours 34 minutes from the aeration basin inlet to outlet;
• 48 hours from oxidation pond inlet to outlet;
• 58 1/2 hours from the bleach plant sewer discharge (cc.7) to
the Coneruh River; and
• 4 3/5 days from the clarifier outlet to the Conecuh River.

The travel times indicated for dye passage in the aeration basin
and oxidation pond were measured from the time of injection until the
first dye trace was detected. The remaining travel times were computed
from dye peak to dye peak after an instantaneous dye dump. The 4.6
days travel time from the clarifier outlet to the Conecuh River includes
an estimated 2-hour travel time from the oxidation pond outlet to the
Franklin Mill Creek spillway, station CC-3. This estimate was based on
several stream velocity measurements and related travel time studies.
Figure 10 shows the visually observed movement of dye through the
aeration basin and the apparent short circuiting. However, there is
still enough retention time in the aeration basin to remove 77 percent,
54 percent and 41 percent of the incoming BOD, COD and TOC, respectively.
Improvement of these reduction rates is a function of time which depends
on increasing the aeration basin's retention time. Two possible
remedies are a simple baffle system and re-alignment of the aerators
using a better rotation scheme to improve mixing.
The travel time through the system of natural lakes to the
Conecuh River was 53 hours. The 4.9 mile, 6-lake system is severly
channeled. The 6 lakes ranging in size from 1.9 acres to 18.6 acres
cover an area of 44.6 acres and have a total volume of 129.4 million
gallons.
CONECUH-ESCAMBIA RIVER BASIN WATER QUALITY
The water quality parameters analysed on water samples collected'
from the Conecuh-Escambia River did not show a standard violation.

37 year average, there was no appreciable difference in dissolved
oxygen, temperature, pH and color at river sampling stations above
and below the Brewton Mill discharge. The minimum dissolved oxygen
observed in the river was 6.8 mg/1 at both Pollard landing and Florida
Highway 4 bridge near Century. The minimum dissolved oxygen at
Edwards Bridge, assumed to exemplify background conditions, was 7.1
mg/1. The temperature in the river varied from 25° to 30° Centigrade
and the pH ranged from 6.5 to 7.2. Color held steady at 10 units at
all river sampling stations. There was a noticeable increase in BOD^
in the Escambia River near Century; however, elevated BOD5S were also
noted in Big Escambia Creek which affects the BOD^ at Century. Average
BOD5 in the Escambia River at Century was 1.9 mg/1 while BOD^s in the
Conecuh River above and below CCA's discharge were 0.8 and 1.0 mg/1,
respectively. Total organic carbon, COD, suspended solids and volatile
solids ranged from 2 to 10 mg/1, 4.0 to 22.4 mg/1, 2 to 36 mg/1, and
zero to 8 mg/1, respectively.
Except for low pH values observed in all tributaries sampled and
the elevated BOD^ in Big Escambia Creek, parameters measured indicate
relatively good water quality in the Conecuh-Escambia River tributaries
(Table V). The pH in Big Escambia, Lictle Escambia and Murder Creeks
were lower than the limit specified in adopted criteria. Minimum pH
values of 5.3, 5.4, 5.5, and 5.6 were observed in Murder, Little
Escambia, Franklin Mill and Big Escambia Creeks,respectively. Previous
survey sampling of these tributaries above any known point source
discharges have also revealed low pH values, and these low values are
assumed to be noriral for stream in this general area. Although Murder

SAMPLING PROCEDURE AND ANALYTICAL METHODOLOGY
SAMPLING PROCEDURE
Samples were collected for 10 days from 8 ln-plant sampling sites
and 7 stream sampling locations. Container Corporatism personnel
assisted in sample collection and all samples were split vith the company.
Twenty-four hour composite samples vere collected at one hour
Intervals at all ln-plant sampling stations. Parameters analyzed included
temperature, pH, color, and BODj. Samples to be analyzed for filterable
and non-filterable solids, PCB's, COD, and TOC vere preserved, if neces-
sary, and returned to the Southeast Water Laboratory at Athens, Georgia
for analysis.
All stream samples were collected by the grab sample method once
per day, except during the first week when samples from sampling stations
E-9 and C0-7 were sampled twice dally. Stream samples were routinely
analysed for DO, pH,temperature, color, BODj, COD, TOC and filterable
and non-filterable solids. All samples were collected at mid-depth
since the stream depths were less than 10 feet. Two collection tech-
niques were employed— DO can sampler and an open bucket. Dissolved
oxygen samples were Immediately carried to the second step of fixation
(addition of alkaline azlde) and placed on ice. The remaining
sample was poured into two 2-liter containers, placed on ice and at
the end of the sample run returned to Che mobile laboratory for processing.
ANALYTICAL METHODOLOGY
The following analytical methods were used by EPA personnel:

DYE STUDY PROCEDURES
Dye studies were perforated June 19-23* Dupont Rhodamine tf. T.
20 dye was used for all Injections and concentrations were measured
by an American Instrument Company Fluorometer. Some samples were
collected manually, but the bulk of collection was with Serco automatic
samplers ~ collecting at 1-hour Intervals.
Three in-plant areas were Investigated for time of travel:
1. Minimum retention times in the aeration basin and oxidation
pond — 14 gallons of dye were dumped prior to the oxygen
injection nozzle at the clarlfler outlet.. Visual inspection
of the dye was first made at the aeration basin inlet pipe.
The dye was then visually followed as long as possible
through the aeration basin. Samples were collected at the
aeration basin and oxidation pond outlets using Serco samplers.
2. Bleach plant waste travel from the sewer line discharge
(CC-7) to the spillway (CC-3) — 1 gallon of dye vas dumped
and sample collection was made with a Serco sampler.
3. Time of travel from the spillway to Brewton Lake discharge
(CC-4) — three dye dumps were made: 3 gallons at the
spillway; 2 gallons at the inlet to Jackson Lake; and 2 gallons
at bridge above Merritt Lake. Samples were collected with
Serco samplers.
