                                EXECUTIVE SUMMARY
PURPOSE AND SCOPE

    The U.S. Environmental Protection Agency (EPA), acting under a consent decree with the Environmental
Defense Fund and the National Wildlife Federation, assessed both human health and environmental risks from
the contaminants 2,3,7,8-tetrachloro dibenzo-p-dioxin (2378-TCDD)  and 2,3,7,8-tetrachloro dibenzofuran
(2378-TCDF) that are discharged from 104 pulp and paper mills located in the United States using chlorine
or its derivatives to bleach pulp.  As a part of this program, the Office of Water Regulations and Standards
(OWRS) was responsible for estimating the potential human health and aquatic life risks associated with
exposures via surface water pathways based on mill-specific effluent sample results.

    This report presents a generalized uniform approach for assessing impacts from the discharges of the
104 mills to support the decision by EPA to either regulate or not regulate discharges of 2378-TCDD and
2378-TCDF from pulp and  paper mills that use chlorine to bleach pulp.  It should be  noted that in some
respects, the approach for assessing risks presented in this report may differ from approaches used by the
States.  For example, States may use different cancer potency factors (either FDA's or their own), fish
consumption rates, or bioconcentration factors.  In some cases States do not use models to predict risks,
but rather use actual fish tissues data. In other cases, States do not use the "toxicity equivalence" procedure
as a means of predicting the combined risk from 2378-TCDD and 2378-TCDF as was used in this report. As
a result of the differences  in approaches taken by various States for  assessing risks and the approach
presented in this report, estimated risks may be over- or underestimated in comparison to the States' adopted
or proposed water quality standards. A summary of State assumptions used to develop 2378-TCDD water
quality standards is presented in Appendix R.

    Effluent sampling results for each of the 104 pulp and paper mills  were provided by the joint EPA/paper
industry 104-mill study. The 104-mill data,  however, are now over two years old, and since the time the 104-miil
study was conducted, conditions at some mills may have changed due to mills taking  actions to install or
incorporate activities identified as necessary to reduce the formation of dioxins or furans, or more recent
information may be available that would alter some of the exposure and risk estimates developed in the present
study. However, because this study was designed to provide a snapshot of exposure and risk estimates at
one point in time, for the most part, no attempt was made to include  effluent data from sources other than
the 104-mill study. The only exception to the use of 104-mill study effluent data was the use of plant flow data
for several mills that were provided by the EPA Regions and which differed from the flow values identified in
the 104-mill study.

    The purpose of this analysis was to develop estimates of exposures and risks to human health and aquatic
life associated with 2378-TCDD and 2378-TCDF discharges from chlorine-bleaching pulp and paper mills.
This study was not designed to rank the exposure or human health  and aquatic life risks associated with
specific mills, but rather to estimate the risk potential posed by the entire chlorine-bleaching pulp and paper
industry. This analysis focused on the highest estimated in-stream contaminant concentrations immediately
downstream of each mill discharge point (assuming steady-state, fully mixed conditions) and the potential
human health impacts resulting from the consumption of 2378-TCDD and 2378-TCDF contaminated fish and
drinking water associated with these exposures. Because no comprehensive studies  on 2378-TCDD and
2378-TCDF build-up in sediments and bioaccumulation up the food chain exist, only the water column was
investigated as a potential route of exposure and uptake of 2378-TCDD and 2378-TCDF  by fish.  However, a
sensitivity analysis is presented to look at bioconcentration in fish both before and after paniculate 2378-TCDD
and 2378-TCDF settle to the sediment.  Carcinogenic and non-carcinogenic effects in humans were con-
sidered, as were potential adverse effects to aquatic life.

-------
    One result of this analysis is an understanding of the potential upper bound human cancer risk to a
hypothetically exposed individual eating contaminated fish and drinking contaminated water near the mills.
These results are presented as the estimated risk of cancer incidence during the exposed individual's lifetime.
No attempt was made to characterize or estimate the human population potentially at risk. For these risk
estimations, reasonable worst-case ambient and  effluent characterizations were used, as well  as  best
estimates of the  physical and chemical properties of 2378-TCDD and 2378-TCDF.  Because not all of the
parameter values used in this assessment are "worst case," the hypothetically exposed individual is not
considered the "most exposed individual."

    Long-term animal studies of 2378-TCDD have provided clear evidence that the contaminant is an animal
carcinogen (Kociba et at., 1978; NTP, 1982a; NTP,  I982b). Based on these animal studies as well as other
considerations, EPA has concluded that 2378-TCDD should be regarded as a probable human carcinogen
(U.S. EPA, 1985). EPA has assigned 2378-TCDD a qualitative weight-of-evidence designation of "B2" for its
carcinogenic potential. This designation indicates that 2378-TCDD is an agent for which there is sufficient
evidence of carcinogenicity based on animal studies but inadequate data regarding its carcinogenicity from
human epidemiologic studies (U.S. EPA, 1986).

APPROACH

    In this investigation, two approaches were used to estimate and compare exposures to 2378-TCDD and
2378-TCDF resulting from surface water effluent discharges from pulp and paper mills. The first approach
consisted of a simple dilution calculation conducted to estimate the  in-stream  concentration of the con-
taminants after the effluent is mixed with the receiving water. This calculation assumes 100% of the in-stream
contaminants (both dissolved and adsorbed to suspended solids) are bioavailable. In the second approach,
the Exposure Assessment Modeling System (EXAMS II)  was used to partition in-stream steady-state con-
centrations of the contaminants between dissolved and paniculate forms.  EXAMS II  is able to account for
the high affinity of 2378-TCDD and 2378-TCDF for solids and, therefore, the likelihood that a percentage of
the contaminants will be associated with suspended and benthic solids. It is assumed that the paniculate
form of the contaminants will not be available for uptake across  fish gills nor available to humans through
ingestion of contaminated drinking water.

    Both the simple  dilution and EXAMS II approaches were used to  estimate and compare the potential
human health risks associated with ingestion of contaminated fish tissue and drinking water. Since the simple
dilution approach assumes 100% of the in-stream contaminants to be bioavailable to fish, this approach
effectively includes exposure through uptake across fish gills (dissolved form) as well as through ingestion of
suspended solids (paniculate form). The simple dilution approach is also considered to represent the upper
bound for bioaccumulation since a bioconcentration factor based on dissolved contaminants was applied to
the paniculate contaminants as well. In the EXAMS II model analysis, however, only the dissolved contaminant
concentration is assumed to be bioavailable to fish.

    Although EXAMS II predicts contaminant concentrations associated with both suspended and benthic
solids, no attempt was made to separately estimate fish exposure to contaminants associated with suspended
participates, bed sediments, or the food chain.  These exposure routes were not directly addressed due to a
lack of adequate information concerning the bioaccumulation of these contaminants through the food chain
and the sediment-to-fish partition coefficient needed to predict uptake through contact with contaminated
sediments.  In addition, it is generally believed that 2378-TCDD and 2389-TCDF tend to adsorb to very fine
suspended sediments which would be transported out of the immediate area of the discharge and therefore
beyond the area under consideration. (These sediment-associated contaminants would, however, pose a
potential risk to fish inhabiting those areas further downstream where the fine sediments are eventually
deposited.) For these reasons, and because uptake of 2378-TCDD and 2378-TCDF through the water column
has been more thoroughly investigated, exposure to dissolved contaminants in the water column was the
basis for estimating fish tissue contamination using the EXAMS II  approach.

    Using exposure estimates from both approaches (simple dilution and EXAMS II water column), fish tissue
contaminant residue levels were estimated by employing fish bioconcentration factors (BCFs) for 2378-TCDD

-------
and 2378-TCDF.  From fish tissue contaminant concentrations, average daily lifetime exposures (or chronic
daily intake, GDI) for humans consuming 6.5,30 and 140 g/day were calculated. These calculations took into
consideration factors that adjust for lower contaminant concentrations in fish muscle (filet) and fatty/oily food
bioavailability in humans of 95% of oral exposure.  Receiving water concentrations were also used to estimate
the average daily lifetime 2378-TCDD and 2378-TCDF exposure associated with drinking water ingestion,
assuming a 2 L/day consumption rate.

    Multiplying average daily lifetime doses by the EPA carcinogenic potency factor for 2378-TCDD yielded
a conservative (upper bound) estimate of the expected rate of cancer incidence above background incidence
rates due to 2378-TCDD exposure.  Combined 2378-TCDD/-TCDF cancer risk was  estimated using the
"toxicity equivalence" (TEQ)  procedure, in which the cancer potency of 2378-TCDF is assumed to be one
tenth that of 2378-TCDD. It should be noted that, although in this report TEQ represents only the contributions
of 2378-TCDD and 2378-TCDF to risk, there are likely to be additional risk contributions from other chlorinated
dibenzo-p-dioxins and furans associated with discharges from chlorine-bleaching pulp and paper mills.
However, 2378-TCDD and 2378-TCDF account for greater than 90% of the TEQ from chlorinated dioxins and
furans found in the effluents of these mills.

    Mill-specific contaminant concentration estimates were also used to calculate the exposure level as-
sociated with a single ingestion of a 0.25 Ib. (115 g) contaminated fish portion. This dose was evaluated
against a 2378-TCDD Health Advisory threshold value for protection against liver effects, estimated by EPA
for this investigation following appropriate guidelines.

    The mill-specific, simple dilution contaminant concentrations for 7Q10 low flow receiving water conditions
(based on the lowest consecutive seven-day average flow during any ten-year period) were compared  to
EPA's preliminary chronic exposure levels for the protection of aquatic life to predict whether chronic toxicity
to aquatic organisms from 2378-TCDD and 2378-TCDF would result under the assessment scenarios.

ASSUMPTIONS USED IN ANALYSIS

    The following is a list of assumptions used in this investigation:

    1)   Mill-specific, five-day effluent composite contaminant concentrations collected during the 104-mill
        study were multiplied by mean plant flow rates to determine contaminant load. This resulting load
        to the receiving stream was assumed to be continuous. The representativeness of the sample ef-
        fluent as reflecting long-term mill operations is unknown; since then, the mills may have made
        plant process or operation changes to reduce dioxin and furan formation.  This assumption may
        overestimate human health and aquatic life risks.

    2)   The highest estimated steady-state in-stream concentrations in the immediate downstream vicinity
        of the discharges (assuming fully mixed conditions) were considered for fish exposure.  Fish are
        likely to move in and out of the area of maximum concentration, but these estimates assumed that
        fish remain exposed to the highest concentration.  Consequently, this assumption is likely to over-
        estimate fish exposure and overestimate human health and aquatic life risks.

    3)   Receiving water stream flow rates for estimating human health risks were calculated  using the har-
        monic mean of historic flow measurements from nearby stream gaging stations.  7Q10 receiving
        water flow rates were used for estimating aquatic life impacts. These flows may not be the same
        as those used by specific States to assess risks. Therefore, these assumptions may over- or un-
        derestimate risks compared to State assumptions.

    4)   Three bioconcentration factor (BCF) values were used for estimating 2378-TCDD and 2378-TCDF
        concentrations in edible fish tissue (the filet): two for 2378-TCDD and one for 2378-TCDF. The
        resulting fish tissue concentrations were used to estimate human exposure to the contaminants
        through consumption of fish tissue.  For 2378-TCDD, a BCF of 5,000 was used in combination with
        a human consumption rate of fish tissue of 6.5 g/day, and a BCF of 50,000 was used in combina-
        tion with consumption rates of 30 g/day and 140 g/day.  The 6.5 g/day fish tissue consumption

-------
       rate in combination with the BCF of 5,000 reflects the assumptions in EPA's ambient water quality
       criterion for 2378-TCDD and 2378-TCDF and is considered a reasonable estimate for an average
       consumer of locally-caught fish. The 30 and 140 g/day consumption rates in combination with the
       BCF of 50,000 are used as sensitivity comparisons and represent more extreme exposure
       scenarios for recreational and subsistence fishermen or other high rate consumers of fish. A
       single BCF for 2378-TCDF of 1,950 was used in combination with each of the three consumption
       rates. BCFs are species-specific and highly variable. This study did not take species variability or
       degree of bioconcentration into account. Also, actual fish consumption rates vary by locale.
       State assumptions for BCF, consumption rates, and also cancer potency may vary from those
       used in this assessment. Therefore, this assessment may overestimate or underestimate risks
       compared to State assessments.

    5)  A drinking water ingestion rate of 2L/day was used to estimate human exposures through inges-
       tion of contaminated drinking water. It was assumed that the water consumed was taken from the
       point of highest in-stream pollutant concentration after the effluent was fully mixed in the receiving
       stream,  and no treatment of the water was undertaken to remove contaminants prior to ingestion.
       This assumption likely overestimates human health risks from drinking water.

    6)  Fish tissue bioavailability for humans was assumed to be 95% of oral dose. Contaminants in water
       were assumed to be 100% bioavailable to both fish and humans. This reflects the most current in-
       formation EPA has on bioavailability, but the assumptions may overestimate the risk to humans.

    7)  Fish were assumed to be exposed to contaminants only in the water column. No food chain or
       sediment associated exposures were considered, other than for the simple dilution method in
       which the total in-stream contaminant level  (both dissolved and adsorbed to suspended solids)
       were bioavailable.

    8)  The estimates of risk apply only to a hypothetically exposed individual in the immediate vicinity of
       the mills, and not to the entire population of fish consumers.

SUMMARY OF RESULTS

    The results of the human health risk and aquatic life impact analyses for the 104 mills included in this
investigation are summarized below. It should be noted that sufficient information was not available for all of
the mills to allow complete evaluation and comparison of results for each of the 104 facilities.  For example,
for several of the mills discharging to open waters (i.e., lakes, open ocean), no information was available on
receiving stream zone of initial dilution, which was necessary for calculating effluent dilution. For a few other
mills, data were  questioned as to their accuracy and new samples were being taken, but the results of the
new sample evaluations were not available for inclusion in this study.  In addition, for some facilities, there
was sufficient information to predict risks based on the simple dilution method, but insufficient information to
predict risk based on the EXAMS II method. Also,  either harmonic mean flow or  7Q10 flow data were not
available for several facilities.

Cancer Risk Associated with Consumption of Contaminated Fish Tissue

    Figures A through D present the predicted distribution of the number of mills for which discharges would
result in a given range of estimated upper bound lifetime cancer risks to the hypothetically exposed individual
due to the consumption of contaminated fish tissue based on the simple dilution exposure assessment method
and the EXAMS  II water  column exposure assessment method.

    The results of calculations using the 6.5 g/day fish tissue consumption rate in combination with the BCF
of 5,000 reflect  the assumptions in EPA's ambient water quality criterion for dioxin and  are considered
reasonable  exposures for average consumers of locally-caught fish.  The results  of these  calculations are
presented separately from the results of calculations using the 30 and 140 g/day consumption rates and BCF
of 50,000, which are considered more extreme exposure scenarios (for example, for recreational and
subsistence fishermen) to be used for sensitivity comparisons.

    1.  Simple Dilution Exposure Assessment Method

    Using the simple dilution exposure assessment estimates, the 6.5 g/day fish tissue consumption rate, and
fish filet contaminant concentrations based on a BCF of 5,000 for 2378-TCDD, the upper bound mill-specific
cancer rates for the hypothetically exposed individual ranged from the 10'2 to 1O"8 risk levels (Figure A). Risk
levels associated with discharges from 80 of the 97 mills evaluated (82%) fell within the 10"4 to 1O"6 risk levels,
with 36 mills within the 10~5 risk level.

    Mill-specific cancer rate estimates using the 30 g/day fish tissue consumption  rate and fish filet con-
taminant concentrations based on a BCF of 50,000 ranged from the  _>_ 10~1 to 10"* risk levels (Figure B).
Seventy of the 97 mills (72%) were associated with risk levels between 10"3 to 10^,  and 39 of these 70 fell
within the 10"3 range. Using the 140 g/day fish tissue consumption rate and fish filet contaminant concentra-
tions based on the 50,000 BCF, risk levels ranged from _>_ 10  to 10*6 (Figure B).  Sixty-six out of the 97 mills
(68%) were associated with risk levels between 10~2 to 10"3, with 40 within the 10"3 range.

    2.  EXAMS II Exposure Assessment Method
    Mill-specific upper bound cancer rate estimates for the hypothetically exposed individual using the EXAMS
II water column exposure assessment method,  6.5 g/day fish tissue consumption rates, and  fish filet
contaminant concentrations based on a BCF of 5,000 for 2378-TCDD ranged from the 10"3 to 10"8 risk levels
(Figure C). Seventy of the 87 mills evaluated (80%) were associated with risk levels between 10"5 (32 mills)
to 10"6 (38 mills).

    Using the 30 g/day consumption rate and fish filet contaminant concentrations based on the 50,000 BCF,
mill-specific cancer rates ranged from the 10~1  to 10~7 risk levels (Figure D). Sixty-four of the 87 mills (74%)
were associated with risk levels within the 10"3 to 1O"4 range, and 41 of these fell within the 10"4 range. Cancer
rate estimates using the  140 g/day fish tissues consumption rate and 50,000 BCF ranged from the _>_ 10~1 to
10"6 risk levels (Figure D). Sixty-three of the 87 mills  (72%) were associated with risk levels between the 10~3
and 10*4 range, and 37 of these fell within the 10"3 range.

Cancer Risks Associated with Ingestion of Contaminated Drinking Water

    Figures E and F present the distribution of the number of mills for which discharges were estimated to
result in a given range of upper bound lifetime cancer risks to the hypothetically exposed individual due to
the ingestion of contaminated drinking water.  Only those facilities discharging to fresh water lakes, rivers,
and streams were included in this analysis. No discharges to marine or estuarine waters were included, since
these water bodies would not be used as drinking water sources.

    Use of the simple dilution method estimated that the cancer risks associated with the 69 mills evaluated
ranged from the 10"4 to 10~9 risk levels (Figure E).  The greatest percentage of these mills (44, or 64%) were
associated with risk levels within the 10   (23 mills) to  10  (21 mills) range.  Use of the EXAMS II water column
method estimated that the risk levels associated with the 64 mills evaluated would range from the 10~5 to 10~9
levels (Figure F). Fifty of these mills (78%) were associated with risk levels between the 10  (18 mills) to 10"
(32 mills) range.

Non-Cancer (Short-Term Exposure) Risks

    Figures G through H present the distribution of the number of mills for which discharges would result in
a given range of human dose due to the single portion consumption of 115 grams of contaminated fish tissue.
The concentrations of fish tissue contaminants used for this assessment were based on a BCF of 50,000 for
2378-TCDD and 1,950 for 2378-TCDF in the edible portion of the fish  (the filet).  Results are reported in
pg/kg/day for comparison to a one-day Health Advisory for protection against liver effects (100 pg/kg/day),
estimated by EPA for this investigation.

    Based on the simple dilution method results (Figure G), the dose associated with discharges from 25 out
of 97 mills evaluated (27%) would equal or exceed the one-day HA dose for protection from liver effects (100

9 mills out of 87 (10%) would equal or exceed the 100 pg/kg/day dose level.

Aquatic Life Impacts

    Aquatic life impacts were estimated based on a comparison of predicted in-stream concentrations of
2378-TCDD and 2378-TCDF (in pg/l) to EPA's preliminary chronic exposure levels for the protection of aquatic
life (0.038 pg/l for 2378-TCDD and 0.41 pg/l for 2378-TCDF). The simple dilution method, using 7Q10 low flow
conditions, predicted that water column concentrations of 2378-TCDD immediately downstream of 80 out of
90 mills (89%) would exceed the chronic  exposure level of 0.038 pg/l (Figure I).  Seventy-four mills (82%)
would exceed the 0.41 pg/l level for 2378-TCDF.

DISCUSSION OF RESULTS

    The results of this study indicate  that, taking into consideration the effects of the assumptions and
simplifications used in this analysis, there  is a potential for high level contamination of the water column by
2378-TCDD and 2378-TCDF from the effluent discharges of many of the chlorine-bleaching pulp and paper
mills investigated.  For each of the mills analyzed, use of the simple dilution exposure assessment method
resulted in higher  estimated water column contaminant concentrations and greater estimated aquatic life
impacts and human health risks than the EXAMS II water column method. This is because the simple dilution
method assumes that all contaminants in the water column, both dissolved and adsorbed to suspended solids,
are bioavailable. The EXAMS II water column method, on the other hand, only considers those contaminants
in the dissolved phase. In those cases where the receiving water TSS (total suspended solids) was relatively
low,  the simple dilution  and EXAMS II water column results are comparable.  When suspended  solids
concentrations were high, however,  the EXAMS II water column method estimated risks significantly lower
than those predicted by the simple dilution method.  Therefore, for those water bodies included in this study
with relatively high suspended solids content, the EXAMS II water column method likely underestimated
human health risk from consumption of contaminated fish tissues, since fish exposure to sediment-adsorbed
contaminants was not considered.

    The primary reason for ignoring the exposure routes through contaminated sediments using EXAMS II
was the lack of acceptable and appropriate fish bioaccumulation factors for this exposure scenario as well
as the tendency for  the contaminants to  associate with the very fine sediment fraction which is typically
transported and deposited well downstream of the immediate discharge vicinity.  As a check and a sensitivity
comparison on this approach, however, the results of the simple dilution calculation are considered to provide
an upper bound on fish tissue contaminant levels.

    In addition to the absence of consideration of sediment and food chain exposure routes in the EXAMS II
method, a number of other simplifications and assumptions have influenced the results of this study, including
the selection and use of  BCFs and fish tissue ingestion rates for the evaluation.  BCFs are highly variable
depending on the  species, and this study did not take into account inter-species  variability in the rate and
degree of  contaminant bioconcentration.  Actual fish tissue consumption rates also vary over time, with
individuals, and in different parts of the  country.   For example, risk estimates  based on the 6.5  g/day
consumption rate and fish filet BCF  of 5,000 for 2378-TCDD were established on  the basis of EPA's water
quality criteria assumptions. The 6.5 g/day rate applies to a national average consumption rate of fish and
shellfish; however, this rate may not be representative of fish consumption rates for recreational or subsistence
fishermen. Also, the 50,000 BCF for 2378-TCDD used  in conjunction with fish consumption rates of 30 and
140 g/day for recreational and subsistence fishermen was based on the assumption that only the filet portion
of the fish is consumed. However, some subpopulations of subsistence fishermen and certain ethnic groups
eat whole fish and crabs in which the concentration of contaminants is likely to be higher than in the filet alone.
Therefore,  the use of a 50,000 BCF for 2378-TCDD may underestimate risks to these subpopulations.

    It should also  be noted that,  if multiple discharges to the same waterbody are present, the actual risk
associated with a waterbody may be substantially greater than estimated in  this study.  For example, there
are several chlorine-bleaching pulp and paper mills that discharge to the Columbia  River basin. Calculations

in this report assume that each mill discharges to a receiving stream with no background level of contamina-
tion. Therefore, in the case of multiple discharges to a receiving stream, estimating risks from one mill alone
can result in a significant underestimate of risk.

    Finally, no assessment of local fish patterns or actual commercial or recreational fishing practices were
conducted as part of this evaluation. Therefore, it is not known whether or not commercially or recreationally
valuable species occur or are taken in the vicinity of the discharges that were included in this evaluation.

    A comparison of predicted cancer versus non-cancer human health risk was also conducted to determine
which of the two end points is the most sensitive. Cancer health risks were estimated to occur for more mills
than non-cancer risks. The results also indicate a potentially greater risk of cancer due to the consumption
of contaminated fish tissue than through the ingestion of contaminated drinking water. It should be pointed
out that this conclusion may only be true for the hypothetically exposed individual and may not be true for
the entire exposed population.  Determining which exposure route poses the greatest  risk to the entire
population would require knowledge of the number of persons eating contaminated fish  tissue versus the
number of persons who use contaminated surface water as a drinking water source.  More of the population
would likely be exposed to a single dose  of contaminated fish tissue than to a lifetime of exposure to
contaminated fish tissue or drinking water taken from the vicinity of  certain  mills. Such a population
assessment was not conducted for this investigation.

    Each of the exposure assessment approaches used in this analysis predict upper bound risks that should
be carefully considered by risk managers while assessing potential impacts associated with the discharge of
2378-TCDD and 2378-TCDF in chlorine-bleaching pulp and paper mill effluents.

                                   1.  INTRODUCTION
1.1    BACKGROUND

    The U.S. Environmental Protection Agency (EPA), acting under a consent decree with the Environmental
Defense Fund and the National Wildlife Federation, assessed both human health and environmental risks from
the contaminants 2,3,7,8-tetrachloro dibenzo-p-dioxin (2378-TCDD) and 2,3,7,8-tetrachloro dibenzofuran
(2389-TCDF) that are discharged from 104 pulp and paper mills located in the United States using chlorine
or its derivatives to bleach pulp. The Office of Toxic Substances (OTS) coordinated this multi-media  risk
assessment. As a part of this program, the Office of Water Regulations and Standards (OWRS), Assessment
and Watershed Protection Division (AWPD) was responsible for estimating the potential human health and
aquatic life risks associated with exposures via surface water pathways based on mill-specific effluent sample
results.

    This report presents a generalized uniform approach for assessing impacts from the discharges of the
104 mills to support the decision by EPA to either regulate or not regulate discharges of 2378-TCDD and
2378-TCDF from pulp and paper mills that use chlorine to bleach pulp. It should be noted that in some cases,
the approach for assessing risks presented in this report differs from approaches used by States. For example,
States  may use different cancer potency factors (either FDA's or their own), fish consumption rates, or
bioconcentration factors. In some cases, States do not use models to predict risks, but rather use actual fish
tissue data. In other cases, States do not use the "toxicity equivalence" procedure as a means of predicting
the combined risk from 2378-TCDD and 2378-TCDF as was used in this report. As a result of the differences
in approaches taken by various States for assessing risks and the approach presented in this report, estimated
risks may be over- or underestimated in comparison to the States' adopted or proposed water  quality
standards. A summary of State assumptions used to develop 2378-TCDD water quality standards is presented
in Appendix R.

    Effluent sampling results for each of the 104 pulp and paper mills were provided by the joint EPA/paper
industry 104-mill study. The 104-milldata, however, are now over two years old, and since the time the 104-mill
study was conducted, conditions at some mills may have changed  due to mills taking actions to install or
incorporate activities identified as necessary to reduce the formation of dioxins or furans, or more recent
information may be available that would alter some of the exposure and risk estimates developed in the present
study.  However, because this study was designed to provide a snapshot of exposure and risk estimates at
one point in time, for the most part, no attempt was made to include effluent data from sources other than
the 104-mill study. The only exception to the use of 104-mill study effluent data was the use of plant flow data
for several mills that were provided  by the EPA Regions and which differed from the flow values identified in
the 104-mill study.

    The focus of this report was to estimate the potential human health and aquatic life impacts resulting from
chlorine-bleaching pulp and paper mill effluent discharges to surface waters. This study was not designed
to rank the exposure or human health and aquatic life risks associated with specific mills, but rather to estimate
the risk potential posed by the entire chlorine-bleaching pulp and paper industry. Because no comprehensive
studies on 2378-TCDD and 2378-TCDF build-up in sediments and bioaccumulation up the food chain exist,
only the water column was investigated as  a potential route of exposure and uptake of 2378-TCDD and
2378-TCDF by exposed fish. However, a sensitivity analysis is presented to look at bioconcentration in fish
both before and after paniculate 2378-TCDD and  2378-TCDF settle to the sediment.  Carcinogenic and
non-carcinogenic effects in humans are considered, as are adverse effects to aquatic life. The chapters that
follow present the methods selected to conduct the investigation, the results of the investigation, and an
analysis of the results.

-------
1.2    PURPOSE AND SCOPE

    The purpose of this analysis was to develop estimates of exposures and risks to human health and aquatic
life from 2378-TCDD and 2378-TCDF discharges from chlorine-bleaching pulp and paper mills. This analysis
focused on the highest estimated in-stream contaminant concentrations immediately down-stream of each
mill discharge point, assuming steady-state, fully mixed conditions.

    In this investigation, two approaches were used to estimate and compare exposures to 2378-TCDD and
2378-TCDF resulting from surface water effluent discharges from pulp and paper mills. In the first approach,
a simple dilution calculation was conducted to estimate the in-stream contaminant concentrations after the
effluent is mixed in the receiving water. This calculation assumes 100% of the in-stream contaminants (both
dissolved and adsorbed to suspended solids) are bioavailable to fish. In the second approach, the Exposure
Assessment Modeling System (EXAMS II) (Bums et al., 1982;  Bums and Cline, 1985; Harrigan and Battin,
1989) was used to partition  in-stream steady-state water column contaminant concentrations between
dissolved and paniculate forms. However, only the dissolved contaminant concentration predicted by EXAMS
II was considered in determining exposure and risk. Both the simple dilution and EXAMS II in-stream exposure
methods were used to estimate the potential human health risks associated with  ingestion of contaminated
fish and drinking water.

    No attempt was made in the EXAMS II approach to estimate fish exposure to contaminants associated
with suspended particulates,  bed sediments, or the food chain. This was due to lack of sufficient and
appropriate data and  understanding of the bioaccumulation of these contaminants through the food chain
and appropriate sediment-to-fish partition coefficients to predict uptake through exposure to contaminated
sediments. In addition,  it is generally believed that 2378-TCDD and 2378-TCDF tend to adsorb to very fine
sediments that settle out of the water column slowly. Therefore, it was assumed that much of the sediment
associated contaminants would be transported out  of the immediate area of the discharge and would be
deposited further downstream. Although there is no doubt that food and sediment provide exposure routes
to fish  downstream where the amount of 2378-TCDD and 2378-TCDF available (i.e.,  dissolved) for uptake
across gills becomes  much less, the assumption that fish remain in the area  immediately downstream from
the point of discharge is probably sufficiently conservative to compensate for any lack of food chain or
sediment associated exposure components. In addition, underthe simple dilution method, all of the in-stream
contaminants are assumed to be available for uptake by fish and therefore both the dissolved and adsorbed
fractions are considered in this method, providing an upper-bound estimate of fish tissue contamination. The
EXAMS II method, on  the other hand, provides a more  reasonable estimate of the direct exposure of fish to
the contaminants from water only.

    One result of this analysis is an upper bound estimate of the potential risk of cancer over the lifetime of a
hypothetically exposed  individual.   No attempt has been  made to characterize the  human population
potentially at risk.  For these risk estimations, reasonable worst-case ambient and effluent characterizations
were used, along with best estimates of physical and chemical properties of 2378-TCDD and 2378-TCDF.
Because not all of the parameter values used in this assessment are "worst-case," the hypothetical^ exposed
individual is not considered the "most exposed individual."

    The probability of an individual developing cancer in a lifetime due to the ingestion of contaminated fish
or drinking water was calculated based on exposure estimates and the EPA carcinogenic potency factor.
Also, the  data for exposure to 2378-TCDD and 2378-TCDF  from bleached  paper mills were screened for
exposure scenarios exceeding an average of 100 pg/kg/day, the one-day  Health Advisory for TCDD for
protection against human liver effects. Exposure scenarios exceeding this level were examined in more detail
to determine whether  the cancer or non-cancer endpoint is the most sensitive indicator of risk.  Exposure
data were also screened for comparison against EPA's preliminary chronic  exposure levels for protection
against adverse  impacts on aquatic life.

    This report presents the approach used to conduct the exposure and risk assessments (Chapter 2), the
results of the investigation (Chapter 3), and a discussion of the results (Chapter 4). Investigation results are
presented in two parts.  The first part addresses potential exposure concentrations of 2378-TCDD and

-------
2378-TCDF found in the water and in the fish tissue ingested by humans.  The second pan presents the
potential human dose of these contaminants resulting from ingestion of contaminated fish tissue and drinking
water, and the potential human health risks associated with each of the routes of exposure.

            2.  EXPOSURE AND RISK ASSESSMENT APPROACH
    This chapter presents a description of the approach used to assess contaminant exposure levels and the
resulting potential human health risks and aquatic life impacts associated with discharges of 2378-TCDD and
2378-TCDF from the 104 chlorine-bleaching pulp and paper mills under investigation. A flow chart depicting
this approach is presented in Figure 2.1. This chapter also describes the critical factors that were considered
during the development of the study approach. A more detailed description of these factors is presented in
Appendix A.

2.1    REQUIREMENTS OF TECHNICAL APPROACH

    The approach taken was designed to incorporate an appropriate balance between the difficulty (detail)
of the analysis and the accuracy of the results. The critical factors considered in the development of the
analytical approach were: 1) in-stream chemical transformation processes, 2) applicability of calculation
methods, 3)  availability of environmental data, and 4) model sensitivity.  Each of these factors is briefly
discussed below.

    The chemical/physical processes thought to most significantly influence the fate of 2378-TCDD and
2378-TCDF in the aquatic environment are dilution and adsorption of the contaminants to participates. Other
processes, such as volatization, hydrolysis, photolysis, and biotransformation do not appear to significantly
affect the fate of the contaminants. Because of the tendency of the contaminants  to adsorb to participates,
it was necessary to calculate the partitioning of 2378-TCDD and 2378-TCDF between the dissolved and solid
phases in the receiving waters.  This required consideration of suspended solids concentrations in receiving
streams.

    A simple dilution calculation  method for estimating water column concentrations of 2378-TCDD and
2378-TCDF provides total in-stream contaminant concentrations  without consideration  of the  effects  of
adsorption to particulates and eventual sedimentation or other fate processes. This method of  predicting
exposure results in worst-case water column exposure estimates. Because  2378-TCDD and 2378-TCDF
appear to have a high affinity for adsorption to particulates, other methods of estimating contaminant fate and
transport are necessary to consider partitioning between the dissolved and solid forms of the contaminants.
The Exposure  Assessment Modeling System (EXAMS II), a state-of-the-art surface  water contaminant
modeling system, is capable of estimating the partitioning of a contaminant between its dissolved form in the
water column and that portion that associates with suspended and  benthic solids.

    Many parameters describing the physical/chemical properties  of 2378-TCDD and  2378-TCDF and
mill-specific effluent and receiving water characteristics are required to operate EXAMS II. Therefore, an effort
was undertaken to assess the availability and quality of data accessible through existing data sources. Both
EPA's Canonical Environmental Data Base (CEDB) and STORET were considered as potential data sources.
CEDB data are only available for a small fraction of the receiving waters for the mills under investigation, and
a majority of the parameters necessary to operate EXAMS II were not available for  any of the mills' receiving
waters.  However, STORET (a water quality data base maintained by EPA's Office of Water that can access
water quality sampling data from  monitoring stations around the country) provides access to data on flow,
total suspended solids (TSS), pH, and other parameters required to operate EXAMS II for most of the mills'
receiving waters. It was concluded that STORET could provide data  of sufficient quality and for enough  of
the mill receiving waters to conduct the EXAMS II assessment.

    A model sensitivity analysis was conducted to determine which  environmental data parameter variations
had the greatest influence on EXAMS II contaminant concentration estimation results under steady-state
conditions and given known 2378-TCDD and 2378-TCDF physical/chemical properties. During the sensitivity
analysis, environmental data parameters (e.g., temperature, stream compartment geometry, TSS) were varied

individually over wide ranges. Resulting in-stream dissolved  concentration variations were noted, if any.
Variations in receiving water total suspended solids levels produced the greatest variations in resulting
in-stream dissolved contaminant concentrations.   Therefore, mill-specific values for receiving water
suspended solids were obtained and used in the EXAMS II analyses.  For discharges to open waters (i.e.,
oceans, lakes, reservoirs), suspended solids values were not available and, therefore, a default value of 10
mg/1 was used  for the EXAMS II analyses.  All other  environmental parameters, except for mill-specific
contaminant loadings and receiving water flow rates, were assigned default values. For those effluent samples
from the 104-mill study for which 2378-TCDD and 2378-TCDF concentrations were below the detection limit
of the analytical method, the value used in this assessment was 1/2 the detection limit.  The evaluations of
some of the mills conducted in this study were  based  on 1/2 the detection limit for both 2378-TCDD and
2378-TCDF, 112 the detection limit for 2378-TCDD in combination with detected concentrations of 2378-TCDF,
or 1/2 the detection limit for 2378-TCDF in combination with detected concentrations of 2378-TCDD.

    Methods used for obtaining all data points used in this analysis are described in detail in Appendix B. The
three tables presented in Appendix C display: 1)  receiving water flow rates, effluent contaminant concentra-
tions and loadings, and TSS values for each mill, 2) default values used in EXAMS II, and 3) the physical/chemi-
cal properties data for 2378-TCDD and 2378-TCDF which were used in EXAMS II modeling runs.

2.2     EXPOSURE ASSESSMENT

2.2.1    In-Stream Contaminant Concentrations

    In this investigation, two approaches were used to estimate and compare exposures to 2378-TCDD and
2378-TCDF resulting from surface water effluent discharges from pulp and paper mills.  The first approach
consisted of a simple dilution calculation conducted to estimate the total, steady-state in-stream concentration
of the contaminants after the effluent is mixed in the receiving water. This calculation assumes 100% of the
in-stream contaminants (both dissolved and adsorbed to suspended solids) are bioavailable to fish. In the
second approach, the Exposure Assessment Modeling  System (EXAMS II) was used to partition in-stream
steady-state concentrations  of the contaminants between dissolved and paniculate forms.

    EXAMS II is able to account for the high affinity of 2378-TCDD and 2378-TCDF for solids and, therefore,
the likelihood that a percentage of the contaminants will be associated with suspended and benthic solids.
Both the simple dilution and  EXAMS II approaches were used to estimate and compare the potential human
health  risks associated with ingestion of  contaminated fish tissue and drinking water.   As mentioned
previously, for the EXAMS  II predictions  of  in-stream contaminant concentrations,  only the dissolved
concentration was assumed to be bioavailable to fish.

   The following simple dilution equation was used  to provide an estimate of the concentration  of a
contaminant downstream from a point source release into a flowing water body after dilution of the substance
by the receiving water (U.S. EPA, 1988b):
where,
    C      =     concentration of substance in stream (mass/volume),
    Ce     =     concentration of.substance in effluent (mass/volume),
    Qe     =     effluent flow rate (volume/time), and
    Qt     =     combined effluent and stream flow rate (volume/time).*

                    assumes wastewater was not originally drawn from the receiving stream

    Although this calculation is easily executed and provides a quantitative estimate of in-stream contaminant
concentration which is limited in precision only by the precision of the input parameters, this calculation
provides only the total in-stream contaminant concentration attributable to the point source.  It does not

-------
provide a distribution of the contaminant between the dissolved and adsorbed states or the downstream
pollutant concentration gradient.

    EXAMS II, on the other hand, is a sophisticated computer modeling system capable of computing the
following parameters:

    l)   "Exposure: the expected... environmental concentrations due to a user-specified pattern of chemi-
        cal loads,

    2)   Fate: the distribution of the chemical in the system and the relative dominance of each transport
        and transformation process, and

    3)   Persistence: the time required for effective purification of the system... once the chemical loadings
        terminate." (Bums and Cline, 1985)

Once input parameters describing the environment (temperature, stream compartment geometry, receiving
water flow, solids, organic carbon fraction, etc.), the chemical contaminant characteristics (molecular weight,
vapor pressure, Henry's Law constant, Kow, Koc, solubility, etc), and the loadings are entered, the model
produces a report detailing the three sets of computations described above.

    For each mill, the calculated water column concentrations were used as the basis for further calculations.
The estimated concentrations were considered 100% available to the aquatic organisms living in the receiving
waters, 100% available to humans using the water as a drinking water source, and 95% available to humans
through fish tissue consumption.

    The mills being investigated in this study can be grouped into one of three categories: direct dischargers
to free flowing streams, direct dischargers to open waters (e.g,  oceans, lakes,  reservoirs), and indirect
dischargers (dischargers to POTWs) to either free flowing streams or open waters.  Contaminant concentra-
tions resulting from direct discharges to free flowing streams were calculated directly using the simple dilution
and EXAMS II water column methods when adequate environmental data were available for the site.

    Contaminant concentrations resulting from direct discharges to open water bodies were calculated using
the simple dilution method, based on zone of initial dilution factors for the mills that were provided by EPA
Regions (Table 2.1) (Albright, 1990; Davis, 1989; Derose, 1989; Fisher, 1989; Greenburg, 1989; Greenfield,
1990; Hall, 1989; Hangarden, 1989; Henry, 1989; Hyatt, 1989; Keefler, 1989; Loster, 1989; Menzardo, 1989;
Tingperg, 1989; and Weeks, 1989). The zone of initial dilution is the region of initial mixing surrounding or
adjacent to the end of the outfall pipe in which aquatic inhabitants may be chronically exposed to concentra-
tions of pollutants  in excess of water quality standards.  Initial dilution is defined  by EPA (1982) as the
flux-averaged dilution (averaged over the cross section area of the  plume) achieved during the period when
dilution  is primarily a result of plume entrainment, and is not dominated by ambient conditions.  Because
EXAMS  II requires stream flow data as input to calculate in-stream contaminant concentrations, and because
flows for open water bodies are not available, it was necessary to back-calculate "surrogate" water body flows
for direct dischargers to open water bodies based on known mill plant flows, and the dilution factors for the
mills.  The following calculation was used to determine surrogate water body flows for direct open water
discharges:

                                        Fo = (D * Fp) - Fp

where,
    Fo =          surrogate open water body flow
    Fp     =     mill plant flow
    D      =     dilution factor

The resulting estimated flow values were then used as input for the EXAMS II assessments.  This procedure
allowed for the use of EXAMS II to estimate partitioning of the contaminant between dissolved and solid forms
in open water discharge cases. In addition, for several mills located on free-flowing streams for which flow

data were not available, dilution ratios provided by the EPA Regions were used to estimate stream flow using
the same procedure as was used for open water discharges (see Table 2.1).

    Contaminant concentrations resulting from indirect discharges to either free flowing streams or open
water bodies were calculated using the same methods described above, except that loadings were decreased
to 2 and 25% of the total to account for the effects of treatment on the discharge effluent stream.

    In-stream contaminant concentrations were calculated using the harmonic mean flow for the receiving
water for use in the human health  risk analysis.  These  concentrations were  used  to calculate human
exposures to the contaminants through fish tissue and drinking water ingestion. The harmonic mean flow is
defined as the reciprocal of the mean value of the reciprocal of individual values.

2.2.2   Whole-Body And Fish Filet Contaminant Concentrations

    Tissue residue levels for fish exposed to the in-stream contaminant concentrations estimated above were
calculated by multiplying the contaminant concentration by estimated bioconcentration factors (BCFs) for
2378-TCDD and 2378-TCDF.  Estimated fish tissue residue levels resulting from exposure to these con-
taminants in the water column were based on BCFs of 5,000 (2378-TCDD, filet only), 100,000 (2378-TCDD,
whole body), and 3,900 (2378-TCDF, whole body).

    For example, assuming a 2378-TCDD water column concentration of 2.2 x lO^ng/l, and a BCF of 5,000,
the contaminant concentration in the fish filet would be calculated as follows:

                        (water column concentration) (BCF)  =  filet concentration
                              (2.2 x lO^ng/l) (5,000) = 1.1 x lO^ng/kg

    The BCF for 2378-TCDD of 5,000 was used to estimate uptake by fish through exposure to the dissolved
contaminant in the water column. This value is the average bioconcentration potential that was exhibited by
the aquatic organisms used to develop human  health criteria for 2378-TCDD for exposure through the
consumption of contaminated fish tissue (USEPA, 1984). This value is based on fish filet residue levels, not
whole body levels. This BCF, in combination with a comparatively moderate fish tissue consumption rate (6.5
g/day), was the basis for estimating human health impacts from the consumption of contaminated fish tissue
based on EPA's ambient water quality criteria assumptions for 2378-TCDD.

    A second BCF of 100,000 used to estimate 2378-TCDD taken up by fish through the water column was
developed primarily from the results of the EPA Duluth Laboratory's most recent studies on the bioconcentra-
tion of 2378-TCDD by fish (Cook, 1990). During these investigations, BCFs for carp and fathead minnows
were determined through laboratory studies with exposures of up to 71 days in duration.  The whole body
BCF values presented in the Cook et al. study ranged from 65,900 ±_ 9,300 (for carp with 9% lipid content)
to 159,000 ±_ 40,000 (for fathead minnows with 19% lipid content).  The Cook study is preliminary and has
not been peer reviewed.  Based on this information, the present assessment selected a reasonably conser-
vative BCF value of 100,000 to represent a more extreme bioaccumulation potential that, in combination with
higher fish tissue consumption rates, result in higher estimated human health risks.  These higher estimated
risks are used for sensitivity comparisons to results using the lower BCF and consumption rates.

    Results of a recent literature review by Nabholz et al. (Unpublished) were used as the basis for selecting
BCF values to determine whole body contaminant concentrations in fish exposed to 2378-TCDF in the water
column. Only three measured fish BCF values for 2378-TCDF were identified, two from water exposures and
one from a dietary source. The geometric mean of the measured BCF values for water exposure (3,900) was
used in the present  study.

    Once taken up  by fish, contaminants are generally distributed unequally among the tissues in the fish.
For example, for many contaminants, high concentrations accumulate in the fish liver, generally an inedible
portion of the fish. Also, whole body residue levels include the viscera, which contain significant quantities
of sediments ingested during feeding.  Because of the affinity of 2378-TCDD and 2378-TCDF for sediment,
high concentrations of contaminants would be found in this inedible portion. Therefore, using the estimated
                                              10

-------
whole-body concentration of  a contaminant would not accurately reflect the human exposure  to the
contaminant resulting from the consumption of the edible portion of the fish (the filet).  In general, the
concentration of 2378-TCDD in fish muscle is about 50% of whole fish concentration (Branson et al, 1985).
To compensate for the unequal partitioning of contaminants between the edible and inedible fish tissues, the
estimated whole-body BCFs of 100,000 (for 2378-TCDD) and 3,900 (for 2378-TCDF) were multiplied by 0.5
to arrive at estimated BCFs for the edible portion of the fish of 50,000 (for 2378-TCDD) and 1,950 (for
2378-TCDF). The 5,000 BCF for 2378-TCDD is based on fish filet residue levels, and, therefore, no adjustments
in the fish tissue 2378-TCDD concentration estimates was necessary.  It should be pointed out that for some
species of shellfish (e.g., mollusks) the whole body (minus the shell) is consumed by humans, and, therefore,
the whole-body contaminant concentration would more accurately reflect human exposure.

    Recent laboratory studies support the use  of 50,000 as a  reasonable BCF to estimate 2378-TCDD
concentration in edible fish tissue (Cook, 1990: Merhle et. al., 1988).  These studies indicate that this value
represents a mid-range prediction of freshwater  exposure situations for fish averaging 7% lipid content, a
reasonable average lipid content for the edible portion of freshwater fish potentially consumed by humans
(Cook, 1990).  This value  is applicable to the total 2378-TCDD amount present in the water (not only that
fraction dissolved in the water).

2.2.3   Drinking Water Concentration

    Drinking water contaminant concentrations were assumed to be the same as the in-stream receiving
water concentrations which were calculated using the simple dilution and EXAMS II water column (i.e.,
dissolved) approaches. It  was assumed that the water that is ingested is taken from  the point of highest
in-stream contaminant concentration after the effluent is fully mixed in the receiving  stream. It was also
assumed that the water is untreated, that is, it is ingested as raw stream water with no removal of contaminants.

2.2.4   Human Exposures From Ingestion Of Contaminated Fish Tissue And Drinking Water

    Human exposure to 2378-TCDD and 2378-TCDF from the consumption of contaminated fish tissue was
estimated based on fish tissue consumption rates of 6.5,30, and 140 g/day. The 6.5 g/day consumption rate
is equivalent to less than two 1/4 Ib meals per month and is cited by EPA (1980) as an average level of fish
and shellfish consumption in the United States, based on both fish eating and non-fish eating populations
(per capita rate).  The 6.5 g/day consumption rate was used in combination with the  fish filet 2378-TCDD
concentration estimates based on a BCF of 5,000 for fish exposed to the contaminant in the water column to
arrive at an average daily lifetime human exposure to 2378-TCDD based on EPA's ambient water quality criteria
assumptions.

    The 30 g/day consumption rate is equivalent to approximately eight 1/4 Ib meals per month  and  is
considered applicable for  typical recreational fisherman. The 140 g/day consumption rate is equivalent to
approximately thirty-eight  1/4 Ib meals per month and is considered a high consumption rate applicable for
subsistence fishermen and other subpopulations known to have high fish ingestion rates, such as many
Orientals and Native American Indians. The 30 and 140 g/day consumption rates are values that can be used
to represent consumption rates for recreational fishermen in any area where there is a large water body present
and widespread contamination is evident (EPA, 1989a). These consumption rates were  used in combination
with the fish filet 2378-TCDD concentration estimates based on a BCF of 50,000 for  fish exposed to the
contaminant in the water column.  Exposure estimates based on the higher BCF and consumption rates
represent more extreme exposure scenarios.

    Estimates of human exposure to 2378-TCDF through the consumption of contaminated fish tissue were
based on the three consumption rates (6.5, 30,  and 140 g/day) in  combination with  fish filet 2378-TCDF
concentration estimates based on a single BCF  (1,950)  for fish exposed to the contaminant in the water
column.

    The average daily lifetime exposure (mg of contaminant/kg of body weight/day over a 70-year lifetime)
was calculated by multiplying the chemical concentration in the edible fish tissue by the ingestion rate and
dividing by an average adult body weight of 70 kg.  For example,  if the estimated level of 2378-TCDD in fish
                                              11

-------
filets is 1.4 x 10~7 mg/kg and the daily fish consumption rate is 6.5 g, the contaminant exposure to a 70 kg
adult is:
                                                         .
                            70 kg  body weight

     The average daily lifetime  human  exposure to 2378-TCDD and 2378-TCDF from the ingestion of
contaminated drinking water was based on a 2 liter/day average lifetime ingestion rate (MAS, 1977). The
average daily lifetime exposure for a 70 kg adult was determined by multiplying in-stream chemical concentra-
tions by a 2 liter/day average lifetime ingestion rate and then dividing by 70 kg.

2.2.5  Aquatic Life Impacts

    Sufficient data are not currently available concerning the chronic effects of 2378-TCDD and 2378-TCDF
on aquatic life to allow EPA to derive national water quality or sediment criteria for these contaminants (EPA,
1984).  However, several exposures that have been conducted for other purposes do provide some informa-
tion concerning the chronic effects of 2378-TCDD and 2378-TCDF on aquatic life.  EPA has developed
preliminary chronic exposure levels for 2378-TCDD and 2378-TCDF based on these existing exposure studies
(EPA, 1989b).

    Potential aquatic life impacts were determined by comparing estimated in-stream concentrations of
2378-TCDD and 2378-TCDF to EPA's preliminary chronic exposure levels for protection of aquatic organisms:
0.038 pg/l for 2378-TCDD and 0.41 pg/l for 2378-TCDF. Water column contaminant concentrations were
calculated using the simple dilution exposure assessment approach and hydrologically-based 7Q10 flow.

2.3    RISK ASSESSMENT

2.3.1   Bioavailable Dose From Ingestion Of Contaminated Fish Tissue And Drinking Water

    Not all of the contaminants that are ingested with fish tissue are available for uptake by humans.  Results
of a recent study conducted by Boyer (1989) suggest that 85%-95% absorption is a reasonable estimate of
2378-TCDD bioavailability in humans from the ingestion of fatty or oily foods, especially milk, fish, and meats.
For the present study, the conservative upper limit of this range of bioavailability (95%) was used. Therefore,
the estimated exposure of humans to 2378-TCDD and 2378-TCDF from the consumption of contaminated
fish was multiplied by .95 to arrive at an estimated human dose. Further characterizations of doses to specific
target organs, via a pharmacokinetic analysis, were not conducted.

    Boyer (1989) also investigated bioavailability of 2378-TCDD from water. Although the author could find
no data that specifically addressed the bioavailability of 2378-TCDD from drinking water, he assumed that the
contaminant would be present at its maximum solubility in water and, therefore, would be 100% bioavailable
for absorption to the gastrointestinal tract.  The present study also assumes that contaminants in drinking
water are 100% bioavailable.

2.3.2  Estimated Cancer Risk From Ingestion Of Contaminated Fish Tissue And Drinking Water

    Long-term animal studies of 2378-TCDD have provided clear evidence that the contaminant is an animal
carcinogen (Kociba et al., 1978; NTP, 1982a; NTP, 1982b).  Based on these animal  studies as well as other
considerations, EPA has concluded that 2378-TCDD should be regarded as a probable human carcinogen
(U.S. EPA, 1985). EPA has assigned 2378-TCDD a qualitative weight-of-evidence designation of "B2" for its
carcinogenic potential. This designation indicates that 2378-TCDD is an agent for which there is sufficient
evidence of carcinogenicity based on animal studies but inadequate data regarding  its carcinogenicity from
human epidemiologic studies (U.S. EPA, 1986).

   The average daily lifetime bioavailable dose (for both fish tissue and drinking water contamination) was
multiplied by the EPA carcinogenic potency factor for 2378-TCDD to calculate a conservative (upper bound)
estimate of the hypothetically exposed individual's cancer incidence rate above background incidence rates
due to 2378-TCDD. The probability of developing cancer in a lifetime due to a given dose of contaminant is
                                              12

-------
represented by the following formula, which estimates a plausible upper limit to excess lifetime risk of cancer
at low doses:

                                          R  =/3(oT

where,
    R      =     cancer risk,
    ft      =     the EPA carcinogenic potency factor, and
    d      =     dose.

           * this formula may not be appropriate for use in high dose/high risk situations where
            there may not be a direct relationship between the observed effect and dose.

    For example, the EPA upper bound carcinogenic potency factor for 2378-TCDD is 1.6 x 105 (mg/kg/day)"1
   !) (EPA,  1985) and
cancer in a lifetime is:
[B2] (EPA, 1985) and if the dose is 6.0 x 10"11 (mg/kg/day) then the probability of an individual developing
                                        R = (1.6x105)(6.0x10"11)
                                        = 1.0x10'5[llB2Il

The actual risk is likely to be lower than the predicted upper limit and could even be zero in some cases.

    Combined 2378-TCDD/-TCDF cancer risk was estimated by converting 2378-TCDF doses to 2378-TCDD
toxicity equivalences (TEQs).  The TEQ value was then multiplied by the carcinogenic potency factor for
2378-TCDD to obtain the combined 2378-TCDD/2378-TCDF risk.  The TEQ was generated by using the toxicity
equivalency factor (TEF) recommended in "Interim Procedures for Estimating Risks Associated with Ex-
posures to Mixtures  of Chlorinated Dibenzo-p-Dioxins  and  Dibenzofurans (CDDs and  CDFs) arid  1989
Updated, Part II" (Barnes et al., 1989). For example, assuming a 2378-TCDD dose of 6.0 x 10"8 mg/kg/day, a
2378-TCDF dose of 2.2 x 10"8 mg/kg/day, and the 2378-TCDF TEF of 0.1, the total TEQ for the 2378-TCDD/-
TCDF mixture is calculated as follows:

                          ((1)(6.0 X 10"8)) + ((0.1) (2.2 X 10"8)) = 6.2 X 10"8

Combined risk is calculated by multiplying the resulting TEQ by the carcinogenic potency factor:

                              6.2 x 10"8 x 1.6 x 105 = 9.9 x 10"3 ["B2"J

    In this study TEQ represents only the contribution of 2378-TCDD and 2378-TCDF to risk. There are likely
to be additional risk contributions from other chlorinated dibenzo-p-dioxins and furans associated with
discharges from chlorine-bleaching pulp and paper mills that are not addressed here.  However, 2378-TCDD
and 2378-TCDF account for greater than 90% of the TEQ from  chlorinated dioxins and furans found in the
effluents of chorine bleaching pulp and paper mills.

2.3.3  Non-Cancer Health Risks From Ingestion Of Contaminated Fish Tissue

    In assessing the risk associated  with 2378-TCDD  and  2378-TCDF exposures, cancer is generally
considered the most sensitive endpoint.  It is assumed that if individuals are protected from significant concern
for cancer, they will also be protected from other endpoint risks such as developmental toxicity,  reproductive
effects, liver toxicity,  immunotoxicity, etc.  However, cancer risks are computed assuming an average  daily
dose over a lifetime of exposure. If individuals were exposed infrequently to relatively high doses over a short
period of time, the risks associated with that level of exposure, when averaged over a lifetime, might not be
significant in terms of carcinogenic risk. However, the individual could be at risk for other health effects from
the short-term exposure.

    EPA has developed a number of methods for evaluating the non-cancer effects of exposure to potentially
toxic pollutants. These include the concept of the Reference  Dose (RfD) and Health Advisories (HAs).  The
RfD is an estimate of the lifetime daily dose to the human population likely to be without any appreciable risk
                                               13

-------
of deleterious effect.  RfOs are generally based on studies involving lifetime exposures of animals and are
formally defined for comparison with lifetime average dose rates in humans. The endpoints of concern in
RfDs developed for 2378-TCDD are reproductive and teratogenic effects.  HAs are developed for exposure
associated with less-than-lrfetime exposures of relatively large doses. HA dose levels are appropriate for
comparison  with single doses or short-term exposures.  HAs for 2378-TCDD  have been developed for
reproductiveAeratogenic effects as well as for other toxic endpoints, such as hepatic effects.

    Both RfDs and HAs are derived from the "No Observed Adverse Effect Level" (NOAEL) determined in the
critical lexicological study, divided by an uncertainty factor selected based on specific attributes of the study.
The uncertainty factor takes into account differences in sensitivity between animals and humans, variability
in susceptibility within human populations, and other factors. The level of uncertainty associated with RfDs
and HAs can have a range of an order of magnitude or greater.

    Although the EPA has determined that reproductive and developmental toxicity in animals are the most
critical or sensitive noncarcinogenic effects to consider for the risk assessment of 2378-TCDD,  some
uncertainty arises as to whether these values are applicable to people of nonproductive age (e.g.,  children
or post-menopausal women), or people who are not reproducing for other reasons.  Therefore, because this
assessment  is  concerned with risks  to the general public and because it is designed to assess risks to
individuals exposed infrequently to relatively high doses over a short period of time, neither RfDs nor HAs
developed for reproductive or teratogenic effects were used. Ratherthe HAs developed for protection against
liver effects from exposures to 2378-TCDD were used for comparison to estimated exposures.

    EPA has developed one-day and  ten-day HAs for protection against liver effects: 1 day -10Opg/kg/day,
and 10 day -10pg/kg/day (Lee, 1989). For this analysis, the data for exposures to 2378-TCDD and 2378-TCDF
from the paper mills were screened for exposure scenarios exceeding an average of 100 pg/kg/day (one-day
HA for protection against liver effects). Exposure scenarios exceeding this level were examined in more detail
to determine whether the cancer or non-cancer endpoint was the more sensitive indicator of risk.

                                       3.  RESULTS
    The results of this investigation are presented in two parts. The first part addresses exposure estimates
and compares the results of the in-stream contaminant concentration calculations that were performed using
the two exposure assessment approaches (simple dilution and  EXAMS II water column).  From these
concentrations, filet residue levels in fish were estimated  by applying fish bioconcentration factors (BCFs)
and human exposure levels from fish tissue ingestion (at three consumption rates) and drinking water ingestion
(at a single consumption rate) were estimated.  The exposure assessment also compares the estimated
concentrations to which fish are exposed to EPA's preliminary chronic life standards for 2378-TCDD and
2378-TCDF.  The fish exposure levels were calculated using the simple dilution method with hydrologically-
based 7Q10 low flow conditions and were used as the basis for estimating potential chronic impacts to aquatic
life.

    For indirect dischargers (dischargers to POTWs), the in-stream contaminant concentrations were based
on the results of using an estimated 75% removal efficiency during treatment of the discharge stream.  The
results for both 75% and 98% removal efficiencies are provided in the appendices.

    The second part of the results presents estimated human health risks associated with the ingestion of
2378-TCDD and 2378-TCDF contaminated fish tissue and drinking water. Bioavailable human doses were
estimated and used to estimate the risk to a hypothetically exposed individual. Cancer risk results are reported
as expected incidence rate of cancer above background rate of cancer incidence associated with site-specific
exposure scenarios.  Non-cancer risks are also assessed by comparing estimated human doses to EPA's
one-day Health Advisory dose for protection against 2378-TCDD induced liver damage.

    It should be noted that sufficient information was not available for all of the mills investigated to allow a
complete evaluation and comparison of results for each of the 104 facilities.  For example, for several of the
mills discharging to open waters (i.e., lakes, open ocean), no information was available on  receiving stream
zone of initial dilution, which was necessary for calculating effluent dilution. For a few other mills, data were
questioned as to their accuracy and new samples were being taken, but  the results of  the new sample
evaluations were not available for inclusion in this study.  In addition, for some facilities there was sufficient
information to predict risks based on the simple dilution method, but insufficient information to predict risk
based on the EXAMS II  method. Also, either harmonic mean flow or 7Q10 flow data were not available for
several facilities.  Although not evaluated as part, of this study, actual fish tissue concentration data from the
National Bioaccumulation Study (NBS) (U.S.EPA,  1989c) are presented in Appendix Q. The data presented
are from fish tissue samples taken close to some of the mills evaluated as  part of the present study.  The
number of facilities included in the Appendix was dependent on the number and location of samples taken
as part of the NBS.

    As was noted previously, an effluent 2378-TCDD and 2378-TCDF concentration of 1/2 the detection limit
was used in this evaluation for those mill samples from the 104-mill study in which contaminant concentrations
were below the analytical level of detection. The number of mills for which exposure and risk estimates were
based on 1/2 the detection limits are identified in each of the figures presented in this results section as well
as in Appendix C of this report.

    In some  instances, more than one sample result from the 104-mill study was available for a given  mill.
However, all exposure and risk calculations are based on effluent concentration levels for individual samples
(i.e., sample concentrations for mills with multiple samples were not combined when calculating results).  The
discussions of exposure and risk presented in this chapter are based on the samples from each mill with the
highest effluent contaminant concentrations.

3.1    EXPOSURE ASSESSMENT

3.1.1   In-Stream Contaminant Concentrations

    Appendix D presents the estimated in-stream 2378-TCDD and 2378-TCDF concentrations (in pg/l) for
each of the samples from the 104 mill sites based on harmonic mean flow. Appendix E presents estimated
in-stream contaminant concentrations using the simple dilution method with hydrologically-based 7Q10 flow.
Concentrations are presented  in pg/l for comparison to EPA's preliminary chronic exposure levels for
protection of aquatic life. For aquatic life impacts, contaminant concentrations for discharges to open water
were calculated by simple dilution using zone of initial dilution or ZIO factors. Since these are not free flowing
streams, low flow conditions do not apply.

    For each of the samples, estimated in-stream 2378-TCDD and 2378-TCDF concentrations based on
harmonic mean flow were highest when calculated using the simple dilution exposure assessment method.
In-stream 2378-TCDD concentrations estimated using the simple dilution method ranged from a high of 3.2
x 10+2pg/l to a low of 4.1 x 10^pg/l. I n-stream 2378-TCDF concentrations ranged from a high of 8.0 x 10+2pg/l
to a low of 1.0 x lO^pg/l.  Usinq the EXAMS II water column method, estimated 2378-TCDD concentrations
ranged from a high of 8.3 x 10  pg/l to a low of 3.4 x 10"5pg/l. Estimated 2378-TCDF concentrations ranged
from 7.1 x I0+2pg/l to 1.1 x lO
    In-stream 2378-TCDD concentration estimates based on simple dilution and 7Q10 flow ranged from
high of 3.2 x 10+2 pg/l to a low of 1.37 x 10"4 pg/l.  Estimated 2378-TCDF concentrations ranged from 1.5
10+3 pg/l to 3.42 x 10"4 pg/l.
    Figures 3.1 and 3.2 illustrate the estimated distribution of mills for which discharges result in 2378-TCDD
and 2378-TCDF concentrations falling within specific concentration ranges (based on harmonic mean flow)
using the simple dilution method (Figure 3.1) and EXAMS II water column method (Figure 3.2). Figure 3.3
illustrates the estimated distribution of mills for which discharges result in contaminant concentrations falling
within specific concentration ranges using the simple dilution method based on 7Q10 flow. All figures are
based on the samples with the highest effluent contaminant concentration for each mill.

3.1.2  Fish Tissue Contaminant Concentrations

    Appendix F presents the mill-specific estimated fish tissue concentrations of 2378-TCDD and 2378-TCDF
using the two exposure assessment methods.  The actual fish tissue  concentrations of 2378-TCDD and
2378-TCDF measured during the National Bioaccumulation Study (NBS) are presented  in Appendix Q. It
should be noted that the National Bioaccumulation Study was conducted during 1985 through 1987, and the
condition of some receiving streams and thus the concentration of contaminants in fish tissues may have
changed since the time the NBS was conducted.

    The highest fish tissue concentrations due to in-stream exposure to the contaminants were estimated by
the simple dilution method. The 2378-TCDD fish tissue concentrations estimated using the 5,000 BCF ranged
from a high of 1.6 x 10"1"3 ng/kg to a low of 2.05 x 10"4 ng/kg.  Using the 50,000 BCF, 2378-TCDD fish tissue
concentrations ranged from a high of 1.6 x 10+4 ng/kg to a low of 2.05 x 10"3 ng/kg. Use of the simple dilution
method estimated 2378-TCDF concentrations in fish tissue (using the single BCF of 1,950) ranging from 1.56
x 10+3 ng/kg to 2.0 x 10"4 ng/kg.

    The EXAMS II water column method resulted in fish tissue concentrations of 2378-TCDD ranging from a
high of 4.15 x 10+2 ng/kg to a low of 1.71 x 10"4 ng/kg using  the 5,000 BCF and from 4.15 x 10  3 ng/kg to
1.17 x 10"3 ng/kg using the 50,000 BCF. The 2378-TCDF fish tissue concentrations estimated by the EXAMS
II water column method ranged from 1.39 x 10+3 ng/kg to 1.49 x 10"3 ng/kg.

    Actual 2378-TCDD concentrations measured during the National Bioaccumulation Study ranged from a
high of 7.17 x 10+1 ngykg to a low of 2.05 x  10"1 ng/kg. 2378-TCDF measured values ranged from 2.07 x
10+2 ng/kg to 1.3 x 10~1 ng/kg. It should be noted that both whole body and filet samples were analyzed in
the NBS.  One half the whole body contaminant concentrations were used to estimate filet concentrations as

presented in Appendix Q. Also, both pelagic and benthic species were evaluated in the NBS. Contaminant
concentrations in benthic species tend to be higher than in pelagic species, although pelagic species are
more often sought and consumed by recreational and subsistence fishermen.

3.1.3  Drinking Water Contamination

    This study assumes that the concentrations of the contaminants expected to be found in drinking water
are the same as those predicted in-stream.  These predicted concentrations are presented in Appendix D.
The distribution of the number of mills for which discharges resulted in in-stream concentrations of the
contaminants within specific concentration ranges are illustrated in Figure 3.1  (for the simple dilution method)
and Figure 3.2 (for the EXAMS II water column method).

3.1.4  Aquatic Life Impacts

    Aquatic life impacts  are estimated based on  a comparison of predicted in-stream concentrations of
2378-TCDD and 2378-TCDF, using the simple dilution  method with 7Q10 flow conditions (see Figure 3.3 and
Appendix E), to EPA's preliminary chronic exposure  levels for the  protection of aquatic life (0.038 pg/l for
2378-TCDD and 0.41 pg/l for 2378-TCDF)(U.S. EPA, 1989b). The estimates presented in Figure 3.3 are based
on the samples with the highest effluent contaminant concentration for each mill evaluated. Water column
concentrations of 2378-TCDD immediately downstream of 80 out of 90 mills  (89%) are estimated to exceed
chronic exposure levels of 0.038 pg/l. Seventy-four mills (82%) exceed the 0.41 pg/l level for 2378-TCDF.

3.2    RISK ASSESSMENT

3.2.1   Bioavailable Dose From Ingestion Of Fish Tissue And Drinking Water

    The bioavailable dose to humans from consumption of contaminated fish tissue was calculated based
on 95% bioavailability and three fish tissue consumption rates:  6.5 g/day in combination with fish tissue
concentrations based on fish filet bioconcentration factors of 5.000 for 2378-TCDD and 1,950 for 2378-TCDF;
and 30 and 140 g/day in combination with fish tissue concentrations based on fish filet bioconcentration
factors of 50,000 for 2378-TCDD and 1,950 for 2378-TCDF. The bioavailable dose from drinking water was
calculated based on a drinking water  ingestion rate of 2 L/day and a 100% oral dose bioavailability. The
mill-specific estimated bioavailable doses of 2378-TCDD and 2378-TCDF from consumption of contaminated
fish tissue based on the simple dilution and EXAMS II methods are presented in Appendix G. Mill-specific
estimated bioavailable doses from ingestion of contaminated drinking water are presented in Appendix H.
These values were used to predict the hypothetically exposed individual's upper bound cancer risk associated
with discharges from each mill.

3.2.2  Estimated Cancer Risk From Ingestion Of Contaminated Fish Tissue And Drinking Water

    Appendix I presents  predicted mill-specific upper bound lifetime risks of cancer to the hypothetically
exposed  individual from consumption of contaminated fish tissue based on the simple dilution and EXAMS
II methods. Appendix J presents the mill-specific upper bound risks of cancer from ingestion of contaminated
drinking water. The cancer risks associated with contaminated fish consumption are presented for 6.5 g/day,
30g/day,  and 140g/day consumption rates. The percent 2378-TCDD contributing to TEQ is also estimated
for contaminated fish tissue consumption in Appendix I and for contaminated drinking water ingestion in
Appendix J.

Contaminated Fish Tissue

    Figures 3.4 through 3.7 present  the estimated distribution of the number of mills for which discharges
would result in a given range of estimated lifetime cancer risks for the hypothetically exposed individual due
to the consumption of contaminated fish tissue based on the simple dilution  exposure assessment method
and the EXAMS II water column exposure assessment method. Estimates are based on the samples with the
highest effluent contaminant concentration for each mill evaluated.

    The results of calculations using the 6.5 g/day fish tissue consumption rate in combination with the
2378-TCDD  BCF of 5,000 are based on  EPA water quality criteria assumptions.  The results of these
calculations are presented separately from the results of calculations using the 30 and 140 g/day consumption
rates in combination with the 2378-TCDD BCF of 50,000, which are considered more extreme scenarios.

    Simple Dilution Exposure Assessment Method

    Using the simple dilution exposure assessment estimates, the 6.5 g/day fish tissue consumption rate, and
fish filet contaminant concentrations based on a BCF of 5,000 for 2378-TCDD, the upper bound mill-specific
cancer rates for the hypothetically exposed individual ranged from the 10~2 to 10 risk levels (Figure 3.4).
Risk levels associated with discharges from 80 of the 97 mills evaluated (82%) fell within the 10   to 10"6 risk
levels, with 36 mills within the 10'5 risk level.

    Mill-specific cancer rate estimates using the 30 g/day fish tissue consumption rate and fish tissue
contaminant concentrations based on a BCF of 50,000 for 2378-TCDD range from the >_ 10~1 to 10"6 risk
levels (Figure 3.5).  Seventy of the 97 mills (72%) were associated with risk levels between 10~3 to 10*4, and
39 of these 70 fell within the 10"3 range.  Using the 140 g/day fish tissue consumption rate and fish tissue
contaminant concentrations based on the 50,000  BCF,  risk levels ranged from .>.10~1 to 10"6 (Figure 3.5).
Sixty-six out of the 97 mills (68%) were associated with risk levels between 10"2 to 10"3 with 40 within the 10"3
range.

    EXAMS II Exposure Assessment  Method

    Mill-specific upper bound cancer rate estimates for the hypothetically exposed individual using the EXAMS
II water column exposure assessment method, 6.5 g/day fish tissue consumption  rates, and fish tissue
contaminant concentrations based on a BCF of 5,000 for 2378-TCDD ranged from the 10~3 to 10"8 risk levels
(Figure 3.6). Seventy of the 87 mills evaluated (80%) were associated with risk levels between 10"5 (32 mills)
to 10"6 (38 mills).

    Using the 30 g/day consumption rate and fish tissue contaminant concentrations based on the 50,000
BCF for 2378-TCDD, mill-specific cancer rates ranged from the >. 10"1 to 10"7 risk levels (Figure 3.7). Sixty-four
of the 87 mills (74%) were associated with risk levels within the 10"3 to 10"4 range, and 41 of these fell within
the 10"4 range. Cancer rate estimates using the 140 g/day fish tissue consumption  rate and 50,000 BCF,
ranged from the >_ 10"1 to 10"6 risk levels (Figure 3.7).  Sixty-three of the 87 mills (72%) were associated with
risk levels between the 10"3 and 10"4 range, and 37 of these fell within the 10"3 range.

Contaminated Drinking Water

    Figures 3.8 and 3.9 present the distribution of the number of mills for which discharges were estimated
to result in a given range of upper bound lifetime cancer risks to the hypothetically exposed individual due to
the ingestion of contaminated drinking water. Only those facilities discharging to fresh water lakes, rivers,
and streams were included in this analysis. No discharges to marine or estuarine waters were included, since
these water bodies would not be used as drinking water sources.

    Use of the  simple dilution method estimated that the cancer risks associated with the 69 mills evaluated
ranged from the 10"4 to 10"9 risk levels (Figure 3.8). The greatest percentage of these mills (44, or 64%) were
associated with risk levels within the 10"6 (23 mills) to 10  (21 mills)  range. Use of the EXAMS II water column
method estimated that the risk levels associated with the 64 mills evaluated ranged from the 10'5 to 10'9 levels
(Figure 3.9). Fifty of these mills (78%) were associated with risk levels between the 10"6 (18 mills) to 10"7 (32
mills) range.

3.2.3   Non-Cancer Health Effects From Ingestion Of Contaminated Fish Tissue

    Appendix K presents the estimated mill-specific human doses from the consumption of a single 115 gram
(1/4 pound) portion of contaminated fish tissue (using at fish filet BCF of 50,000 for 2378-TCDD and 1,950 for
278-TCDF) based on the simple dilution and EXAMS II water column exposure assessment methods. Results

                           4.  DISCUSSION OF RESULTS
4.1    ASSUMPTIONS, LIMITATIONS, AND UNCERTAINTIES

    This chapter presents the assumptions that were made during the planning and conduct of this study and
discusses significant results and the limitations and uncertainties associated with those results. The following
is a list of assumptions used in this investigation:

    1)  Mill-specific, five-day composite effluent contaminant concentrations collected during the 104-mill
       study were multiplied by mean plant flow rates to determine contaminant load. This resulting load
       to the receiving water was assumed to be continuous. The representativeness of the effluent
       sample as reflecting long-term mill operations is unknown; since then, the mills may have made
       plant process or operation changes to reduce dioxin and furan formation. This assumption may
       overestimate human health and aquatic life risks.

    2)  The highest estimated in-stream concentrations in the immediate vicinity of the discharges (assum-
       ing steady-state, fully mixed conditions) were considered for fish exposure. Fish are likely to move
       in and out of the area of maximum concentration, but these estimates assumed that fish remain ex-
       posed to the highest concentration. Consequently, this assumption is likely to overestimate fish
       exposure and overestimate human health and aquatic life risks.

    3)  Receiving water stream flow rates for estimating human health risks were calculated using the har-
       monic mean of historic flow measurements from nearby stream gaging stations. 7Q10 receiving
       water flow rates were used for estimating aquatic life impacts. These flows may not be the same
       as those used by specific States to assess risks. Therefore, these assumptions may over- or un-
       derestimate risks compared to State assumptions.

    4)  Three bioconcentration factor (BCF) values were used for estimating 2378-TCDD and 2378-TCDF
       concentrations in edible fish tissue (filet):  two for 2378-TCDD and one for 2378-TCDF.  The  result-
       ing fish tissue concentrations were used to estimate human exposure to the contaminants through
       consumption of fish tissue. For 2378-TCDD, a BCF of 5,000 was used in combination with a
       human consumption rate of fish tissue of 6.5 g/day, and a BCF of 50,000 was used in combination
       with consumption rates of 30 g/day and 140 g/day. The 6.5 g/day fish tissue consumption rate in
       combination with the BCF of 5,000 reflects the assumptions in EPA's ambient water quality
       criterion for 2378-TCDD and 2378-TCDF and is considered a reasonable estimate for an average
       consumer of locally caught fish.  The 30 and 140 g/day consumption rates in combination with the
       BCF of 50,000 are used as sensitivity comparisons and represent more extreme exposure
       scenarios for recreational and subsistence fishermen. A single BCF for 2378-TCDF of 1,950 was
       used in combination with each of the three consumption rates.  BCFs are species-specific and
       highly variable. This study did not take species variability or degree of bioconcentration into ac-
       count.  Also, actual fish consumption rates vary by locale. State assumptions for BCF,  consump-
       tion rates, and also cancer potency may vary from those used in this assessment.  Therefore, this
       assesmsent may overestimate or underestiamte risks compared to State assessments.

    5)  A drinking water ingestion rate of 2L/day was used to estimate human exposures through inges-
       tion of contaminated drinking water. It was assumed that the water consumed was taken from the
       point of highest in-stream pollutant concentration after the effluent was fully mixed in the receiving
       stream, and no treatment of the water was undertaken to remove contaminants prior to ingestion.
       This assumption likely overestimates human health risk from drinking water.
                                              31

-------
    6)   Fish tissue contaminant bioavailability for humans was assumed to be 95% of oral dose. Con-
        taminants in water were assumed to be 100% bioavailable to both fish and humans. This reflects
        the most current information EPA has on bioavailability, but the assumptions may overestimate
        the risk to humans.

    7)   Fish were assumed to be exposed to contaminants only in the water column.  No food chain or
        sediment associated exposures were considered, other than for the simple dilution method in
        which the total in-stream contaminant level (both dissolved and adsorbed to suspended solids)
        were bioavailable.

    8)   The estimates of risk apply only to a hypothetically exposed individual in the immediate vicinity of
        the mills, and not to the entire population of fish consumers.

    In evaluating the results of this study, it should be pointed out that BCFs are highly species specific. The
BCF for a contaminant in a given fish species Is dependent on fish tissue lipid content, mode of contaminant
uptake, and other factors. Thus using a single BCF does not take into account interspecies differences in the
rate and degree of  contaminant bioconcentration.  For example, the study conducted by Cook et. al.
(Unpublished) indicates that a higher BCF than that used in this study (i.e., 200,000) may be applicable for
2378-TCDD for some species of fish.  Also, the 50,000 BCF for 2378-TCDD used in  conjunction  with fish
consumption rates of 30 and 140 g/day for recreational and subsistence fishermen is based on the assumption
that only the filet portion of the fish is consumed. However, some subpopulations of subsistence fishermen
and certain ethnic groups eat whole fish in which the concentration of contaminants is likely to be higher than
in the filet alone.  Therefore, the use of a BCF of 50,000 may underestimate risks to these subpopulations.

    The predictions  from the present study also do  not take  into consideration the mobility of fish in the
receiving waters. Both resident and migrating species will move in and out of the discharge area. This study
assumes that the fish remain exposed to the predicted contaminant concentration up to the  time they are
caught, thus resulting in a conservative estimate of aquatic life impacts and human health risk. In addition,
no assessment of local fish patterns or actual commercial or recreational fishing practices were conducted
as part of this evaluation.  Therefore, it is not known whether or not commercially or recreationally valuable
species occur or are taken in the vicinity of the discharges that were included in this evaluation.

    No attempt was made to estimate fish exposure to contaminants associated with suspended participates,
bed sediments, or the food chain (except when considering the results of the simple dilution method in which
total contaminant concentrations, both  dissolved and adsorbed to suspended particulates, are evaluated).
This was due to the lack of sufficient and appropriate scientific data and understanding of the bioaccumulation
of these contaminants by fish through these routes of exposure.  Although there is no doubt that food and
sediment provide exposure routes to fish downstream where the amount of 2378-TCDD and 2378-TCDF
available (i.e., dissolved) for uptake across gills  becomes much less, the assumption that fish  remain in the
area immediately downstream from the point of discharge is probably sufficiently conservative to compensate
for any lack of food  chain or sediment associated exposure components. In addition, as a check and a
sensitivity comparison, the results of the simple dilution calculation are considered to provide an upper bound
on fish tissue contaminant levels since 100% of the in-stream contaminants were assumed to be bioavailable.

    The assumed fish tissue consumption rates also have an impact on study results.  Actual fish tissue
consumption rates vary over time,  between individuals, and in different parts of the country.  Therefore, in
some cases this evaluation scenario may have underestimated risks, in other cases it may have overestimated
risks.  For example, the fish tissue consumption rate of 6.5 g/day is considered by EPA to be an  average level
of fish and shellfish  consumption in the United  states.  The 6.5 g/day rate applies to a national  average
consumption rate offish and shellfish; however, this rate may not be representative offish consumption rates
for recreational or subsistence fishermen. Therefore, risks estimated based on this consumption rate may,
in some cases, significantly underestimate risk.

    Although EPA recommends the use of 7Q10 as a design flow for stressed aquatic systems, use of 7Q10
receiving water flow rates does not necessarily result in the extreme worst-case scenario for aquatic life
                                               32

-------
impacts. 7Q10 is defined as the lowest consecutive seven-day average flow over a ten-year period.  However,
it is possible that even brief exposures (I.e., less than seven days) to high concentrations of 2378-TCDD and
2378-TCDF can result in toxic effects to aquatic organisms, and such effects may occur after an appreciable
delay following only brief exposures.

    It should also be noted that, if multiple discharges to the  same waterbody are present, the actual risk
associated with a waterbody may be substantially greater than estimated in this study. For example, there
are several chlorine-bleaching pulp and paper mills that discharge to the Columbia River basin. Calculations
in this report assume that each mill discharges to a receiving stream with no background level of contamina-
tion. Therefore, in the case of multiple discharges to a receiving stream, estimating risks from one mill alone
can result in a significant underestimate of risk.

    For each of the mills analyzed, the simple dilution exposure assessment method resulted in  higher
contaminant concentrations and greater aquatic life impacts and human health risks than did the EXAMS II
water column method. This is because the simple dilution method assumes that all contaminants in the water
column, both dissolved and adsorbed to suspended solids, are bioavailable.  The EXAMS II water column
method, on the other hand, considers only those contaminants in the dissolved phase.  In those cases where
the receiving water TSS was relatively low, the  simple dilution and EXAMS II water column results are
comparable. However, when suspended solids concentrations were high, the EXAMS II method estimated
risks significantly lower than those predicted by the simple dilution method. Therefore, in those water bodies
with relatively high suspended solids content, the EXAMS II method likely underestimated human health risks
from consumption of contaminated fish tissue, since fish exposure to sediment-absorbed contaminants was
not considered.

    Study results  indicate that the fish tissue exposure route poses a greater human cancer risk  to the
hypothetically exposed individual than does the drinking water exposure route. However, the upper  bound
cancer risk  estimated from consumption of contaminated fish tissue based on the 6.5 g/day consumption
rate and 5,000 BCF are relatively close to the cancer risk estimates based on ingestion of contaminated
drinking water. It should be pointed out that fish tissue consumption may not pose a greater risk to the entire
population than ingestion of contaminated drinking water.  Determining which exposure route poses the
greatest risk to the entire population would require knowledge of the number of persons eating contaminated
fish tissue versus the number of  persons who use contaminated surface water as a drinking water source.
Such a population assessment was not conducted for this study.

    A comparison of the cancer versus non-cancer risks associated with 2378-TCDD and 2378-TCDF
discharges from pulp and paper mill effluents indicates that more mills would result in potential cancer risks
than would result in non-cancer risks. However, the non-cancer risk may actually be the more sensitive end
point. The cancer risk was estimated for the lifetime of a continuously exposed individual.  The non-cancer
risk, on the other hand, was predicted based on the consumption  of a single portion of contaminated fish
tissue.  More of the population would likely be exposed to a single dose of contaminated fish tissue than to
a lifetime of consuming contaminated fish tissue or drinking water taken from the vicinity of certain mills. In
addition the single dose used to predict the noncancer effects was a relatively modest serving of 115 g  (about
1/4 Ib.) which is less than an enthusiastic person might eat at one sitting.

    Included in Appendix Q are  actual measured fish tissue contamination data from the National  Bioac-
cumulation Study (NBS). It should be pointed out that the fish tissue contaminant concentrations measured
in the NBS may not be representative of actual ambient conditions at a given mill. The NBS samples that
were used for this evaluation were taken from sites close to pulp and paper mills using chlorine for bleaching.
However, the sites may have been several miles from the mill, and not  immediately downstream.  In some
cases the samples were taken several miles upstream of the mills.  In addition, the NBS sample analyses were
performed on composites composed of several fish of different sizes (within a given range) from which aliquots
were prepared and analyzed. This sample analysis procedure would tend to "average" contaminant con-
centration values.  In addition, finfish will migrate in and out of an area and therefore the fish sampled from
the NBS were not likely to be exposed to a constant level of contamination throughout their lifetime, as was
assumed for the simple dilution and EXAMS II assessments.  Some of  the fish evaluated in the NBS were
                                               33

bottom-feeding fish which are rarely consumed by humans. Therefore, careful precautions should be taken
before attempting to compare fish tissue contaminant levels found in NBS and those estimated in this study
and used to predict risks.

    The prediction of human health risk presented in this study apply to hypothetically exposed individuals
in the immediate vicinity of discharges only, using previously described assumptions. To more completely
assess the potential risks posed by discharges from pulp and paper mills that use chlorine to bleach pulp, it
would be necessary to predict the population exposed to 2378-TCDD and 2378-TCDF from these discharges.
Predictions of the population exposed to 2378-TCDD and 2378-TCDF in the environment using site specific
effluent and receiving stream characteristics (as were used in this study) were beyond the scope and resources
of this study.  One consequence of not conducting a population assessment is uncertainty concerning the
extent of human exposure and total population risks associated with discharges of 2378-TCDD and 2378-
TCDF.

4.2     CONCLUSIONS

    Taking  into account the above assumptions, simplifications, and limitations, the results of this study
indicate that there is a potential for high levels of 2378-TCDD and 2378-TCDF  contamination in the water
column resulting from surface water effluent discharges from many of the chlorine-bleaching pulp and paper
mills investigated. These predicted contaminant concentrations could represent significant implications for
human health and aquatic life.  Each of the exposure assessment approaches used in this analysis predict
upper bound risks that should be carefully considered by risk managers while assessing potential impacts
associated  with the discharge of 2378-TCDD and 2378-TCDF in chlorine-bleaching pulp and  paper mill
effluents.

        EVALUATION AND SELECTION OF ESTIMATION METHOD



A.1    REQUIREMENTS OF TECHNICAL APPROACH

   Although it is desireable to obtain maximum accuracy in exposure/risk assessments, a practical balance
must be found between the difficulty of the analysis and the accuracy of its predictive estimates. In order to
develop estimates of contaminant exposures and risks associated with 2378-TCDD and 2378-TCDF dischar-
ges at the 104 pulp and paper mills under consideration, a technically sound, yet feasible, method of estimation
was required. This section discusses factors which were  critical to the methods development/selection
process.  Critical factors considered were: 1) analysis of in-stream chemical transformation processes, 2)
applicability of calculation methods, 3) assessment of the availability of environmental data, and 4) appraisal
of model sensitivity.

A.1.1   Analysis Of In-Stream Chemical Transformations

   The physical and chemical  properties of 2378-TCDD and 2378-TCDF that influence their fate in natural
waters were investigated.  These properties are summarized in Table A.1, and discussed below.

A. 1.1.1 Physical/Chemical Properties of 2378-TCDD

   At 20°C, pure 2378-TCDD is a white crystalline solid with a density of 1.827 g/ml.  In water, 2378-TCDD
solubility (S) is between 0.0193 figfl (at 22°C) and 0.317^g// (at 25°C). The octanol-water partition coefficient
is large (log Kow = 6.15-7.28) as expected, due to low water solubility.

   Because of the high Kow, 2378-TCDD discharged to surface waters is expected to adsorb to suspended
and bedded sediments and also to bioconcentrate in fish. For example, a typical river might contain 50 mg/l
suspended solids (TSS) with 1 percent organic carbon (foe). In such a river, the partition coefficient, Kp, for
2378-TCDD is:

                                      Kp =  0.63 foe Kow
                                         = (0.63)(0.01)(107) = 63,000

where an octanol-water partition coefficient of 107 has been used  for the calculations.  The fraction of
2378-TCDD in the dissolved state can be calculated as follows:

                                  C             1
                                  °t    1+KpX TSS x10"6

                                       _           1	
                                         1 + (63,000) (50) 10~6

                                           = 0.24

Consequently, most of the 2378-TCDD discharged to the river will be adsorbed to suspended and benthic
sediments.

    A second process that could influence the fate of 2378-TCDD is volatilization.  A reliable indicator of the
importance of volatilization is Henry's Law Constant, which for 2378-TCDD is 2.1 x 10"6 atm • m3 /mol at 25°C.
This is a relatively small value, and indicates that 2378-TCDD volatilizes very slowly.

    Although little information is available for other fate processes (hydrolysis, photolysis, and biotransfor-
mation), available data indicate that otherfate processes are not significant. Therefore, dilution and adsorption
to sediments are likely to be the primary processes which control the fate of 2378-TCDD in surface waters.
Processes such as resuspention of sediments due to bottom turbulence or desorption of contaminants from
particles may result in contaminants reentering the  water column.  However, the rates at which these
processes occur and their significance to the  overall fate of these contaminants is not certain. These
processes are probably highly site-specific and intermittent, depending upon the  physical  and chemical
characteristics of the receiving water. In this investigation, we have assumed steady-state conditions at which
there is no net loss or gain of sediment or dioxin between the water column and benthic sediments.

A. 1.1. 2 Physical/Chemical Properties of 2378-TCDF

    At  25°C, 2378-TCDF is a also a white crystalline solid.  The octanol-water partition, like 2378-TCDD, is
large (log Kow = 5.82). Because of the high Kow, 2378-TCDF discharged to surface waters is expected to
adsorb to suspended and bedded sediments and also to bioconcentrate in fish.

    Due to the tendency of both 2378-TCDD and 2378-TCDF to adsorb to sediment, it is necessary to calculate
the partitioning of 2378-TCDD and 2378-TCDF between the dissolved and solid phases in the receiving waters.
This requires determination of suspended solids concentrations in the receiving streams.

A. 1.2  Applicability of Calculation Methods

    Assessing both human health and aquatic life risks requires the initial determination of an estimated
in-stream contaminant concentration. Once these concentrations have been calculated for the appropriate
receiving water flow conditions, in the case of  aquatic life risk determinations, subsequent comparisons
against the OTS Hazard Assessment (U.S. EPA, 1989b) chronic guidelines for water quality are made.  For
human risks associated with exposure from fish and drinking water ingestions, dose and risk are calculated
from in-stream contamination concentrations by employing a series of standard bioconcentration factors,
bioavailability factors, and ingestion  rates. This multiple exposure/risk approach allows for an analysis of the
sensitivity of risk levels.

    Two calculation methods for estimating highest worst-case in-stream contaminant concentrations were
considered, a simple dilution calculation and a method using EXAMS II. A brief discussion of each follows.

A. 1.2.1 Calculating Simple Dilution

    The following simple  dilution equation provides  an estimate of the  concentration of a contaminant
downstream from a point source release into a flowing water body, after dilution of the substance by the
receiving water (EPA, 1988b):
                                             -o

where,
    C      = concentration of substance in stream (mass/volume),
    Ce     = concentration of substance in effluent (mass/volume),
    Qe     = effluent flow rate (volumeAime), and
    Qt     = combined effluent and stream flow rate (volume/time).*

    * assumes wastewater was not originally drawn from the receiving stream

    Although this calculation is easily executed and provides a quantitative estimate of in-stream contaminant
concentration which  is limited in precision  only by the precision of the input parameters, this calculation
provides only the total in-stream contaminant concentration attributable to the point source.  It does not
provide a distribution of the contaminant between the dissolved and adsorbed states or the downstream
pollutant concentration gradient. This exposure estimation assumes all the 2378-TCDD and 2378-TCDF
dissolved in the water column and adsorbed to suspended solids are bioavailable.
                                               A-3

-------
A. 1.2.2 EXAMS II Modeling

    The Exposure Assessment Modeling System (EXAMS II) is a state-of-the-art surface water contaminant
modeling system which can compute:

    1)  "Exposure: the expected... environmental concentrations due to a user-specified pattern of
       chemical loadings,

    2)  Fate: the distribution of the chemical in the system and the relative dominance of each transport
       and transformation process, and

    3)  Persistence: the time required for effective purification of the system... once the chemical load-
       ings terminate." (Burns and Cline, 1985)

    This system is accessible through OTS's Graphical Exposure Modeling System (GEMS) and can take
advantage of a resident set of environmental data called the Canonical Environment Data Base (CEDB).

    Once input parameters describing the environment (temperature, compartment geometry,  receiving
water flow, solids, organic carbon fraction, etc.), the chemical contaminant characteristics (molecular weight,
vapor pressure, Henry's Law constant, Kow, Koc, solubility,  etc.), and the loadings are entered, the model
produces a report detailing the three sets of computations described immediately above.

    Although this model is powerful and fulfills the requirements imposed by the need for estimates of
dissolved contaminant concentration, it requires significant  effort to develop and enter environmental data
into the system. This can be addressed in part by making the CEDB available through GEMS. In GEMS, the
user can identify the stream segment for which environment data are desired by entering the unique reach
number for a particular stream segment. GEMS will access the CEDB, attempt to locate the appropriate
environment, and, if successful, will prepare an environment data file which can be automatically loaded into
EXAMS II.  When CEDB data are not available for a stream environment, environmental data can be obtained
through other data sources, such as STORET. This data must be entered directly to EXAMS II, it can not be
automatically loaded.

    Because EXAMS II best meets the requirements of this assessment and because it "is recommended for
use over most other models" for surface water fate analysis (EPA, 1988b), EXAMS II was selected for estimating
in-stream contaminant concentrations.

A. 1.3  Assessing the Availability of Environmental Data

    As discussed  briefly above, in order to properly operate EXAMS II for this assessment, basic physi-
cal/chemical properties of 2378-TCDD and  2378-TCDF, as well  as mill-specific contaminant loadings and
descriptive environmental data must be entered. To determine the simplifying assumptions appropriate for
this exposure assessment, a multi-phase approach to assessing data availability was undertaken.

A. 1.3.1 Determining CEDB Data Quality and Availability

    Initially, an inventory of the CEDB was conducted to determine if environmental data for each of the 79
mills known to discharge into free-flowing streams were available and reliable. Of the 28 sites for which data
sets were available, significant gaps in each data set were observed.  The available environmental data (in
addition to arithmetic mean flow values) consist primarily of physical compartment geometry data, seepage
flow, suspended sediment concentrations, and bulk density of benthic sediments. In most cases, the majority
of the other parameters used by the EXAMS II model were not available for these 28 sites.

    Because CEDB data were incomplete for the purpose of this study and because of specific requirements
for exposure analyses for harmonic mean flow conditions for human health exposure estimates, the CEDB
was not considered further as a source of environmental data for the purposes of this assessment.

-------
A. 1.3.2 Determining Data Availability Through REACH, STORET, and GAGE

    A  thorough interrogation of STORET data bases (indexed by reach numbers from the Reach File)
indicated the availability of flow (from GAGE stations), total suspended solids, pH, and water temperature
data for most of the mill sites.

    STORET is a water quality data base maintained by EPA's Office of Water. It provides access to water
quality sampling data from monitoring stations around the country.  The GAGE System is maintained by the
U. S. Geological Survey and provides stream flow gage station numbers and their locations (by reach, river,
state, and region).  It can provide continuous flow data from each gage station and can calculate average
and 7010 flow conditions. The GAGE System  can also be accessed through STORET.  The REACH File
presents an index for all river and stream reach segments. Each reach segment is given a unique identification
number which can be used to access other reach-specific water quality data through STORET.

    Of the 104 mills under consideration, 98 had available reach identification  numbers by which data of
interest could be extracted.  Of these, 79 discharge to free flowing streams, 19 discharge to other waters or
reach types (e.g., lakes, coastline, wide river shoreline). Reach characteristics  are displayed in Table A.2.
This information is provided in more detail in Appendix L

    *NOTE:    Two of these mills are in Alaska, which has not been indexed in the Reach File.  Informa-
               tion about four of the mills was vague; Reach Nos., if any, were not available for this as-
               sessment.
    For each of the 79 mills discharging to free-flowing streams, nearby stream gages and monitoring stations
were identified via STORET.  For each of these mills, the nearest streamgage with a relatively long recent
record (generally greater than 15 years) for which there is information available in the STORET flow file, was
selected and manually plotted on a reach map. In a few cases, two gages were selected if the gages bracketed
the mill or if they represented two upstream branches. Out of the 79 mills, 57 are gaged based on this analysis
and 22 are not gaged.  Several of the ungaged streams are major rivers such as the Ohio River, Mississippi
River, Susquehanna River for which there is adequate gaging information at other locations. For those pulp
and paper mills not discharging to free flowing streams and some mills discharging to free flowing streams
                                              A-5

for which gaging information is not avaiaible, contaminant concentrations were based on dilution factors for
these water bodies (provided by EPA Regional Offices).

    For the 79 mills discharging to free-flowing streams, both an INDEX run and an INVENTory run were
conducted on STORET. This identified monitoring stations (and gages and dischargers) on a flow path from
the mills. Based on this information, a schematic (stick diagram) of the streams 5 miles downstream to 10
miles upstream of each mill  was prepared. Dischargers and monitoring stations were identified on the
schematic.  (See Appendix M for an example of this information for one mill). For monitoring stations, the
schematic indicates whether sample information was available for temperature (T), pH (P), and solids (S).
Each mill was classified as follows:

    0      =      no quality data available (8 mills)
    1      =      only downstream data available (within 5 miles) (9 mills)
    2      =      upstream data available for 1 or 2 of the parameters (11 mills)
    3      =      upstream data available (within 10 miles) for S (51 mills)

Mill-specific information availability for mills discharging to free flowing streams is provided in more detail
in Appendix N.

    Based on the  findings of the data survey described above, it was concluded that sufficient data were
available to create EXAMS II environmental files for the 79 mills located on free-flowing streams or rivers.

    Because EXAMS II requires stream flow data as input to calculate in-stream contaminant concentrations,
and because flows for open water bodies are not available, it was necessary to back-calculate  "surrogate"
water body flows for direct dischargers to open water bodies based on known plant flows, and the dilution
factors for the mills. The following calculation was used to determine surrogate water body flows for direct
open water discharges:

                                        Fo =  (D * Fp) - Fp

where,
    Fo      =                surrogate open water body flow
    Fp      =      mill plant flow
    D      =      dilution factor

    The resulting estimated flow values were then used as input forthe EXAMS II assessments. This procedure
allowed the use of EXAMS II to estimate partitioning of the contaminant between dissolved and  solid forms
in open water discharge cases.  This procedure was also used to estimate flow values for some free flowing
streams for which  no gaging information was available.

A. 1.4  Appraising Model Sensitivity

    In order to determine the environmental data parameter variations to which the EXAMS II  model was
sensitive - under steady state conditions and given known 2378-TCDD and  2378-TCDF physical/chemical
properties - standard boilerplate environment and loading files were created. Environmental data parameters
were varied individually over wide ranges. Resulting in-stream concentration variations were noted, if any.

    As  expected, due to 2378-TCDD and 2378-TCDF affinity for adsorption to solids, dramatic variations in
effluent and receiving water suspended solids levels produced dramatic variations in  resulting calculated
in-stream and benthic solids contaminant concentrations. Because variations of these  parameters affected
calculated contaminant concentrations and because these data were readily available  through STORET, it
was determined that mill-specific values of suspended solids for each of the 79 mills discharging to free-flowing
streams would be obtained and supplied to the EXAMS  II model. For discharges to open water bodies, a
default suspended sediment value of 10 mg/l was used and supplied to the EXAMS II model.

    In-stream contaminant concentrations  (at steady-state)  were not, however,  significantly affected by
variations in stream temperature and compartment size. Default values for stream temperature and compart-
                                              A-6

-------
ment geometry were used for all sites. Remaining environmental parameters (e.g., meteorological conditions,
and others) were not considered to be important to the estimation of in-stream contaminant concentrations.
Concentrations for each mill were calculated using default values for these parameters.

    Appendix C presents a list of environmental and effluent parameter values used for each site, including
default values.

                                    DATA SOURCES
B.1    EFFLUENT DATA

    Effluent sampling results for each of the 104 pulp and paper mills were provided by the joint EPA/paper
industry 104-mill study. Continuous loading values (mass/time) for each effluent sample were determined by
multiplying the concentration of the contaminant (mass/vol) by the effluent flow rate (vol/time). Plant flow
data were also supplied by the 104-mill study. For some mills, effluent flow data provided by the EPA Regions
and the States were used which did not agree with the flow data provided by the 104-mill study.

    Effluent sampling data and plant flow data are included in Appendix C. For those samples in which effluent
contaminant concentrations were below the detection limit of the analytical instrument (indicated as "ND" in
Appendix C), the value used in the exposure assessment is 1/2 the detection limit.  For those samples for
which contaminant concentrations in the effluent were not quantified by the analytical lab, the value reported
is annotated with an "NQ." No loadings, concentrations, or risks were estimated based on "NQ" samples.

B.2    RECEIVING WATER STREAM  FLOW DATA AND ADJUSTMENTS

B.2.1   Low Flows for Aquatic Life Effects

    For the calculation  of the chronic  exposure levels for aquatic life, in-stream dissolved contaminant
concentration were calculated using the hydrologically-based 7010 low flow for all mills on streams or rivers.

B.2.2.  Harmonic Mean Flows For Human Health Effects

    For each of the 79 mills discharging to free-flowing streams, in-stream contaminant concentrations were
calculated using the harmonic mean flow for the receiving water. These concentrations were used to calculate
human exposures to the contaminants.  The harmonic mean flow is defined as the reciprocal of the mean
value of the reciprocal of individual values.

    Harmonic mean flow values were obtained/calculated in the following manner.

       Identify a stream gage representative of the flow in the receiving stream.
       Access the daily flow values for the period of record from the STORET/GAGE daily flow file.
       Adjust the daily flow values to reflect likely differences in flow, if any, between the gage site  and
       the mill.
       Compute the harmonic mean using SAS.
       Examine the results and adjust the HMF value, if necessary.

    A description of the specific methodology which was used follows. For each mill, a stream gage was
selected  from the STORET/GAGE daily flow file.  The criteria used in selecting  a gage were:  locational
relationship of the gage and the mill, and length of the record. Generally, the gage with a sufficiently long
record (usually 15 years) that was located closest (coincidental drainage area) to the mill was selected.  In
most cases, the reach location (reach and milepoint) for gages were known from inspection of the IFD file.
This is referred to as Method 1 in the output results (Appendix P).  For other gages, the latitude/longitude
values available in the STORET/GAGE daily flow file were used to determine the gage location on maps. This
is referred to as Method 2. For a few mills, there were no gages located on a direct flow path to the mill.  In
these cases, a nearby gage (usually in the same hydrologic catalog unit) with similar size drainage area was
identified and used. This is referred to as Method 3.  Finally, for three mills, the available reach plot did not
provide a clear description of the receiving stream. For these cases (Method 4), no estimates of the stream
flows were made, since site-specific stream configurations were needed to understand the flow regime.
                                              B-l

-------
    Since, in almost all cases, the gage is not located at the mill site, adjustments in the gage information
were required. These adjustments were made based on drainage area ratios and discharges at the mill.  Either
of two separate gaging scenarios were identified (see Figure B.1): a) the gage was located upstream of the
mill; or b) the gage was located downstream of the mill. In either case, a "drainage area factor" was calculated
as follows:

               DRAINAGE AREA FACTOR = drainage area at mill/drainage area at gage

    Drainage area values were available from the STORET daily flow file for gages.  Drainage areas for mills
were estimated by scaling off areas from the reach maps.  If the drainage area factor was greater than 1.05
or less than 0.95, then the individual daily flow values were multiplied by this factor prior to calculating the
harmonic mean. If the factor was between 0.95 and 1.05, then it was assumed that the gage was sufficiently
representative of the flow at the mill such that no adjustment was needed.

    The second potential adjustment applied to those cases where the gage was located upstream of the mill
and the discharge from the mill was of sufficient magnitude that it would affect the flow in the stream. If the
mill discharge exceeded 5% of the average streamflow at the mill (based on the mean flow value available
from the REACH File), then the mill discharge flow was added to the area-adjusted stream flow values prior
to calculating the harmonic mean. For the few cases where a non-connected nearby gage was used (Method
3), the mill discharge was added to the area-adjusted flow values.

    Following the calculation of the harmonic mean, the results were examined for unreasonably large
differences between the harmonic mean and arithmetic mean. This would generally be caused by a significant
number of very low stream flow values in the historical record. For those cases where there was a significant
difference, the actual stream flow records were examined to determine whether the flows appeared to be
reasonable or contain data errors. If there were obvious data errors (either zero flows inter-mixed in larger
flows or very high flows), then these data points were eliminated prior to recalculating the harmonic mean.
True high flows from episodic events, such as heavy rains  and floods, were retained.  Additionally, if the
harmonic mean was significantly less than the arithmetic mean and the gage was upstream of the mill, then
the "5% rule" was reapplied to determine whether the mill discharge should be added to the streamflow values
prior to recalculating the harmonic mean.

    The results of the harmonic mean calculations are presented in Appendix P for the 79 mills on free flowing
streams plus four mills located on the Columbia River (which is identified in the Reach File as a wide river, but
for which good stream flow information is available). For the three gages for which estimates were not made,
detailed diagrams of the discharge location and stream configuration are needed.  In each of these cases,
the Reach File maps showed "loops" in the stream (i.e., the stream bifurcated near the mill) or other anomalous
situations. It should be noted that some changes in the flow rates used in the assessment were made based
on comments received from the EPA Regions.

B.3   TOTAL SUSPENDED SOLIDS DATA AND ADJUSTMENTS

    Due to the significant tendency of 2378-TCDD and 2378-TCDF to adsorb to sediment, it is necessary to
calculate the partitioning of 2378-TCDD and 2378-TCDF between the dissolved and solid phases in the
receiving waters. This requires site-specific data for suspended solids concentrations in the receiving streams.

    For each of the mills, an estimate of the total solids in the receiving stream (immediately upstream of the
discharge point) was required. Ideally, this estimate should correspond to a flow value approximating the
harmonic mean flow. Suspended solids concentrations are estimated based on historical values from a single
monitoring station upstream of and in the vicinity of the mill.  A two-step search was conducted: 1) stations
within 10  miles upstream, on the same hydrologic stream level, and designated as "ON" the reach in STORET,
and 2) if that did not detect a usable station, then a larger search (usually 25 miles but sometimes 50-100
miles for  large rivers) with no restriction concerning the ON-OFF code.  A station was selected based on
closeness to mill, length of record and vintage of data. The station description was checked manually to
ensure that the station was actually on the same mainstem as the mill. The results of this analysis are presented
in Appendix 0.
                                              B-2

-------
    An adjustment ratio was used in developing the final estimated suspended solids content to ensure that
the predicted total solids in the receiving stream corresponded to a flow value approximating harmonic mean
flow. The ratio is the harmonic mean flow (at the selected stream gage) divided by the arithmetic mean flow,
and the adjusted suspended solids is this ratio multiplied by the mean suspended solids.  This calculation
assumes that suspended solids are linearly related to flow and that as flow goes to zero so does suspended
solids. Results are presented in Appendix O for 62 mills (out of the 79 discharging to free flowing streams
and 4 discharging to the Columbia River).  For the remaining mills, no monitoring stations were found. For
some of the stations used in the analysis, very few observations were available.  Some TSS values were also
provided by the EPA Regions.

HO • Not detected In the effluent sample.  Risk estimates are  based on  1/2 the detection limit In the effluent sample.
NQ > NonquantIf table


Recent  laboratory evidence Indicates that use of a BCF of 50,000 would more accurately reflect the uptake of  2378-TCOD by fish.   Therefore,  risk estimates based on a fish filet BCF of 5.000 may underestimate
risks by an order of magnitude.

 TO: Jim Pagenkopf.
 FROM: Walter Grayman
 RE: Progress on Mill Inventory
 DATE: June 2,1989

    I have finished the first phase on the inventory process; namely, investigating what
 type of information is available and putting together a package of info for a pilot mill.
 I'm using mill VA0003115 as my example. I've attached 6 exhibits showing different
 information and methods of displaying the information as follows:

 EXHIBIT 1: A tree structure printoff for the hydrologic catalog unit in which the mill is
    contained.  If the mill is at the extreme downstream end of the catalog unit (as is the
    case for this mill), it may be useful to also generate the tree for the next downstream
    catalog unt.

 EXHIBIT 2: A STORET inventory of monitoring stations in the vicinity of the mill.  I
    selected a search of all stations within 10 miles upstream of the mill or within 5
    miles downstream of the mill. I also limited this search to stations reporting values
    for temperature, pH and/or solids.  In this case there were 6 stations and a overall
    summation of all this data.

 EXHIBIT 3: An example of the same type of inventory retrieval but considering all
    parameters. This results in many more stations and considerably more output.

 EXHIBIT 4: A hand drawn tree of the reaches within 10 miles U/S and 5 miles 0/S
    showing discharger, monitoring and gaging stations.

 EXHIBIT 5: A summary of information available from the STORET daily flow file
    containing most information that is available from USGS.  I selected the closest
    station to the discharger and in this case the only one on the mainstem of the
    Pamunkey River.

 EXHIBIT 6: A reach plot on which I have put the location of the mill and the stream flow
    gage.

    I should note that the process of acquiring and organizing this information is not a
 automated seamless process.  For example, the STORET flow file is not keyed to the
 Reach File so I need to  use another series of programs to identify appropriate gages
 and then access that information.

   Through June 2,1 have spent 22 hours and approximately $25 in expenses. I
suspect that when I get into production I can probably average about 1  hour per mill. It
would help to have a prioritization (e.g. mills not in GEMS first?).  Any comments or
questions are welcome.  I'll proceed along refining this process for other mills.  I
received your letter of May 31 and I will not go beyond the 40 hour limit unless I hear
from you.
                                      M-l

                                EXECUTIVE SUMMARY
PURPOSE AND SCOPE

    The U.S. Environmental Protection Agency (EPA), acting under a consent decree with the Environmental
Defense Fund and the National Wildlife Federation, assessed both human health and environmental risks from
the contaminants 2,3,7,8-tetrachloro dibenzo-p-dioxin (2378-TCDD)  and 2,3,7,8-tetrachloro dibenzofuran
(2378-TCDF) that are discharged from 104 pulp and paper mills located in the United States using chlorine
or its derivatives to bleach pulp.  As a part of this program, the Office of Water Regulations and Standards
(OWRS) was responsible for estimating the potential human health and aquatic life risks associated with
exposures via surface water pathways based on mill-specific effluent sample results.

    This report presents a generalized uniform approach for assessing impacts from the discharges of the
104 mills to support  the decision by EPA to either regulate or not regulate discharges of 2378-TCDD and
2378-TCDF from pulp and  paper mills that use chlorine to bleach pulp.  It should be noted that in some
respects, the approach for assessing risks presented in this report may differ from approaches used by the
States.  For example, States may use different cancer potency factors (either FDA's or their own), fish
consumption rates, or bioconcentration factors. In some cases States do not use models to predict risks,
but rather use actual  fish tissues data. In other cases, States do not use the "toxicity equivalence" procedure
as a means of predicting the combined risk from 2378-TCDD and 2378-TCDF as was used in this report. As
a result of the  differences  in approaches taken by various States for assessing risks and the  approach
presented in this report, estimated risks may be over- or underestimated in comparison to the States' adopted
or proposed water quality standards. A summary of State assumptions used to develop 2378-TCDD water
quality standards is presented in Appendix R.

    Effluent sampling results for each of the 104 pulp and paper mills were provided by the joint EPA/paper
industry 104-mill study. The 104-mill data, however, are now over two years old, and since the time the 104-mill
study was conducted, conditions at some mills may have changed due to mills taking actions to install or
incorporate activities identified as necessary to reduce the formation of dioxins or furans, or more recent
information may be available that would alter some of the exposure and risk estimates developed in the present
study.  However, because this study was designed to provide a snapshot of exposure and risk estimates at
one point in time, for the most part, no attempt was made to include  effluent data from sources other than
the 104-mill study. The only exception to the use of 104-mill study effluent data was the use of plant flow data
for several mills that were provided by the EPA Regions and which differed from the flow values identified in
the 104-mill study.

    The purpose of this analysis was to develop estimates of exposures and risks to human health and aquatic
life associated with 2378-TCDD and 2378-TCDF discharges from chlorine-bleaching pulp and paper mills.
This study was not designed to rank the exposure or human health and aquatic life risks associated with
specific mills, but rather to estimate the risk potential posed by the entire chlorine-bleaching pulp and paper
industry. This analysis focused on the highest estimated in-stream contaminant concentrations immediately
downstream of each mill discharge point (assuming steady-state, fully mixed conditions) and the potential
human health impacts resulting from the consumption of 2378-TCDD and 2378-TCDF contaminated fish and
drinking water associated with these exposures. Because no comprehensive studies on 2378-TCDD and
2378-TCDF build-up  in sediments and bioaccumulation up the food chain exist, only the water column was
investigated as a potential route of exposure and uptake of 2378-TCDD and 2378-TCDF by fish. However, a
sensitivity analysis is presented to look at bioconcentration in fish both before and after paniculate 2378-TCDD
and 2378-TCDF settle to the  sediment.  Carcinogenic and non-carcinogenic effects in humans were con-
sidered, as were potential adverse effects to aquatic life.

-------
    One result of this analysis is an understanding of the potential upper bound human cancer risk to a
hypothetically exposed individual eating contaminated fish and drinking contaminated water near the mills.
These results are presented as the estimated risk of cancer incidence during the exposed individual's lifetime.
No attempt was made to characterize or estimate the human population potentially at risk. For these risk
estimations, reasonable worst-case ambient and  effluent characterizations were used, as well as  best
estimates of the physical and chemical properties of 2378-TCDD and 2378-TCDF.  Because not all of the
parameter values used in this assessment are "worst case," the hypothetically exposed individual is not
considered the "most exposed individual."

    Long-term animal studies of 2378-TCDD have provided clear evidence that the contaminant is an animal
carcinogen (Kociba et at., 1978; NTP, 1982a; NIP,  I982b). Based on these animal studies as well as other
considerations, EPA has concluded that 2378-TCDD should be regarded as a probable human carcinogen
(U.S. EPA, 1985). EPA has assigned 2378-TCDD a qualitative weight-of-evidence designation of "B2" for its
carcinogenic potential. This designation indicates that 2378-TCDD is an agent for which there is sufficient
evidence of carcinogenicity based on animal studies but inadequate data regarding its carcinogenicity from
human epidemiologic studies (U.S. EPA, 1986).

APPROACH

    In this investigation, two approaches were used to estimate and compare exposures to 2378-TCDD and
2378-TCDF resulting from surface water effluent discharges from pulp and paper mills. The first approach
consisted of a simple dilution calculation conducted to estimate the  in-stream concentration  of the  con-
taminants after the effluent is mixed with the receiving water. This calculation assumes 100% of the in-stream
contaminants (both dissolved and adsorbed to suspended solids) are bioavailable. In the second approach,
the Exposure Assessment Modeling System (EXAMS II)  was used to partition in-stream steady-state  con-
centrations of the contaminants between dissolved and paniculate forms.  EXAMS II  is able to account for
the high affinity of 2378-TCDD and  2378-TCDF for solids and, therefore, the likelihood that a percentage of
the contaminants will be associated with suspended and benthic solids.  It  is assumed that the paniculate
form of the contaminants will not be available for uptake across fish gills nor available to humans through
ingestion of contaminated drinking  water.

    Both the simple dilution and EXAMS II approaches were used to  estimate and compare the potential
human health risks associated with ingestion of contaminated fish tissue and drinking water. Since the simple
dilution approach assumes 100% of the in-stream contaminants to be bioavailable to fish, this approach
effectively includes exposure through uptake across fish gills (dissolved form) as well as through ingestion of
suspended solids (paniculate form). The simple dilution approach is also considered to represent the upper
bound for bioaccumulation since a bioconcentration factor based on dissolved contaminants was applied to
the paniculate contaminants as well. In the EXAMS II model analysis, however, only the dissolved contaminant
concentration is assumed to be bioavailable to fish.

    Although EXAMS II predicts contaminant concentrations associated with both suspended and benthic
solids, no attempt was made to separately estimate fish exposure to contaminants associated with suspended
paniculates, bed sediments, or the food chain.  These exposure routes were not directly addressed due to a
lack of adequate information concerning the bioaccumulation of these contaminants through the food chain
and the sediment-to-fish partition coefficient needed to predict uptake through contact with contaminated
sediments.  In addition, it is generally believed that 2378-TCDD and 2389-TCDF tend to adsorb to very fine
suspended sediments which would be transported out of the immediate area of the discharge and therefore
beyond the area under consideration. (These sediment-associated contaminants would, however, pose a
potential risk to fish inb;oiting those areas further downstream where the fine sediments are eventually
deposited.) For these reasons, and because uptake of 2378-TCDD and 2378-TCDF through the water column
has been more thoroughly investigated, exposure to dissolved contaminants in the water column was the
basis for estimating fish tissue contamination using the EXAMS II approach.

    Using exposure estimates from both approaches (simple dilution and EXAMS II water column), fish tissue
contaminant residue levels were estimated by employing fish bioconcentration factors (BCFs) for 2378-TCDD
                                               VI

and 2378-TCDF. From fish tissue contaminant concentrations, average daily lifetime exposures (or chronic
daily intake, COI) for humans consuming 6.5,30 and 140 g/day were calculated. These calculations took into
consideration factors that adjust for lower contaminant concentrations in fish muscle (filet) and fatty/oily food
bioavailability in humans of 95% of oral exposure. Receiving water concentrations were also used to estimate
the average daily lifetime 2378-TCDD and 2378-TCDF exposure associated with drinking water ingestion,
assuming a 2 Uday consumption rate.

   Multiplying average daily lifetime doses by the EPA carcinogenic potency factor for 2378-TCDD yielded
a conservative (upper bound) estimate of the expected rate of cancer incidence above background incidence
rates due to 2378-TCDD exposure.   Combined 2378-TCDD/-TCDF cancer risk was estimated using the
"toxicity equivalence" (TEQ) procedure, in which the cancer potency of 2378-TCDF is assumed to be one
tenth that of 2378-TCDD. It should be noted that, although in this report TEQ represents only the contributions
of 2378-TCDD and 2378-TCDF to risk, there are likely to be additional risk contributions from other chlorinated
dibenzo-p-dioxins and  furans associated with discharges from chlorine-bleaching pulp and paper mills.
However, 2378-TCDD and 2378-TCDF account for greater than 90% of the TEQ from chlorinated dioxins and
furans found in the effluents of these mills.

   Mill-specific contaminant concentration estimates were also used to calculate the  exposure level as-
sociated with a single ingestion of a 0.25 Ib.  (115 g) contaminated fish  portion.  This dose was evaluated
against a 2378-TCDD Health Advisory threshold value for protection against liver effects, estimated by EPA
for this investigation following appropriate guidelines.

   The mill-specific, simple dilution contaminant concentrations for 7Q10 low flow receiving water conditions
(based on the lowest consecutive seven-day  average flow during  any ten-year period)  were compared to
EPA's preliminary chronic exposure levels for the protection of aquatic life to predict whether chronic toxicity
to aquatic organisms from 2378-TCDD and 2378-TCDF would result under the assessment scenarios.

ASSUMPTIONS USED IN ANALYSIS

   The following is a list of assumptions used in this investigation:

   1)  Mill-specific, five-day effluent composite contaminant concentrations collected during the  104-mill
       study were multiplied by mean plant flow rates to determine contaminant load. This resulting load
       to the receiving stream was assumed  to be continuous. The representativeness of the sample ef-
       fluent as reflecting long-term mill operations is unknown; since then, the mills may have made
       plant process or operation changes to reduce dioxin and furan formation. This assumption may
       overestimate human health and aquatic life risks.

   2)  The highest estimated steady-state in-stream concentrations in the immediate downstream vicinity
       of the discharges (assuming fully mixed conditions) were considered for fish exposure. Fish are
       likely to move in and out of the area of maximum concentration,  but these estimates assumed that
       fish remain exposed to the highest concentration.  Consequently, this assumption is likely to over-
       estimate fish exposure and overestimate human health and aquatic life risks.

   3)  Receiving water stream flow rates for estimating human health risks were calculated using the har-
       monic  mean of historic flow measurements from nearby  stream gaging stations. 7Q10 receiving
       water flow rates were used for estimating aquatic life impacts. These flows may  not be the same
       as those used by specific States to assess risks. Therefore, these assumptions may over- or un-
       derestimate risks compared to State assumptions.

   4)  Three bioconcentration factor (BCF) values were used for estimating 2378-TCDD and 2378-TCDF
       concentrations in edible fish tissue (the filet): two for 2378-TCDD and  one for 2378-TCDF. The
       resulting fish tissue concentrations were used to estimate human exposure to the contaminants
       through consumption of fish tissue. For 2378-TCDD, a BCF of 5,000 was used in combination with
       a human consumption rate of fish tissue of 6.5 g/day, and a BCF of 50,000 was used in combina-
       tion with consumption rates of 30 g/day and 140 g/day. The 6.5  g/day fish tissue consumption

-------
       rate in combination with the BCF of 5,000 reflects the assumptions in EPA's ambient water quality
       criterion for 2378-TCDD and 2378-TCDF and is considered a reasonable estimate for an average
       consumer of locally-caught fish.  The 30 and 140 g/day consumption rates in combination with the
       BCF of 50,000 are used as sensitivity comparisons and represent more extreme exposure
       scenarios for recreational and subsistence fishermen or other high rate consumers of fish. A
       single BCF for 2378-TCDF of  1,950 was used in combination with each of the three consumption
       rates. BCFs are species-specific and highly variable. This study did not take species variability or
       degree of bioconcentration into account. Also, actual fish consumption rates vary by locale.
       State assumptions for BCF, consumption rates, and also cancer potency may vary from those
       used in this assessment. Therefore, this assessment may overestimate or underestimate risks
       compared to State assessments.

    5)  A drinking water ingestion rate of 2L/day was used to estimate human exposures through inges-
       tion of contaminated drinking water. It was assumed that the water consumed was taken from the
       point of highest in-stream pollutant concentration after the effluent was fully mixed in the receiving
       stream, and no treatment of the water was undertaken to remove contaminants prior to ingestion.
       This assumption likely overestimates human health risks from drinking water.

    6)  Fish tissue bioavailability for humans was assumed to be 95% of oral dose. Contaminants in water
       were assumed to be 100% bioavailable to both fish and  humans. This reflects the most current in-
       formation EPA has on bioavailability, but the assumptions may overestimate the risk to humans.

    7)  Fish were assumed to be exposed to contaminants only in the water column.  No food chain or
       sediment associated exposures were considered, other than for the simple dilution method in
       which the total in-stream contaminant level  (both dissolved and adsorbed to suspended solids)
       were bioavailable.

    8)  The estimates of risk apply only to a hypothetically exposed individual in the immediate vicinity of
       the mills, and not to the entire population of fish consumers.

SUMMARY OF RESULTS

    The results of the human health risk and aquatic life impact analyses for the 104 mills included in this
investigation are summarized below. It should be noted that sufficient information was not available for all of
the mills to allow  complete evaluation and comparison of results for each of the 104 facilities. For example,
for several of the  mills discharging to open waters (i.e., lakes, open ocean), no information was available on
receiving stream zone of initial dilution, which was necessary for calculating effluent dilution.  For a few other
mills, data were questioned as to their accuracy and new samples were being taken, but the results of the
new sample evaluations were not available for inclusion in this study.  In addition, for some facilities, there
was sufficient information to predict risks based on the simple dilution method, but insufficient information to
predict risk based on the EXAMS II method. Also,  either harmonic mean flow or 7Q10 flow data were not
available for several facilities.

Cancer Risk Associated with Consumption of Contaminated Fish Tissue

    Figures A through D present the predicted distribution of the number of mills for which discharges would
result in a given range of estimated upper bound lifetime cancer risks to the hypothetically exposed individual
due to the consumption of contaminated fish tissue based on the simple dilution exposure assessment method
and the EXAMS II water column exposure assessment method.

    The results of calculations using the 6.5 g/day fish tissue consumption rate in combination with the BCF
of 5,000 reflect the assumptions in EPA's ambient water quality criterion  for  dioxin  and are considered
reasonable exposures for average consumers of locally-caught fish. The results of these calculations are
presented separately from the results of calculations using the 30 and 140 g/day consumption rates and BCF
of 50,000, which are considered more extreme exposure scenarios  (for  example, for recreational and
subsistence fishermen) to be  used for sensitivity comparisons.

    1.  Simple Dilution Exposure Assessment Method

    Using the simple dilution exposure assessment estimates, the 6.5 g/day fish tissue consumption rate, and
fish filet contaminant concentrations based on a BCF of 5,000 for 2378-TCDD, the upper bound mill-specific
cancer rates for the hypothetically exposed individual ranged from the 10"2 to 10"8 risk levels (Figure A). Risk
levels associated with discharges from 80 of the 97 mills evaluated (82%) fell within the 10^ to 10"6 risk levels,
with 36 mills within the 10"5 risk level.

    Mill-specific cancer rate estimates using the 30 g/day fish tissue consumption rate and  fish  filet con-
taminant concentrations based on a BCF of 50,000 ranged from the  >. 10~1 to ID"6 risk levels (Figure B).
Seventy of the 97 mills (72%) were associated with risk levels between 10"3 to 10"4, and 39 of these 70 fell
within the 10"3 range.  Using the 140 g/day fish tissue consumption rate and fish filet contaminant concentra-
tions based on the 50,000 BCF, risk levels ranged from %_ 10  to 10"6 (Figure B). Sixty-six out of the 97 mills
(68%) were associated with risk levels between 10~2 to 10"3, with 40 within the 10"3 range.

    2.  EXAMS II  Exposure Assessment Method

    Mill-specific upper bound cancer rate estimates for the hypothetically exposed individual using the EXAMS
II water column  exposure assessment method, 6.5 g/day fish  tissue consumption  rates,  and fish filet
contaminant concentrations based on a BCF of 5,000 for 2378-TCDD ranged from the 10"3 to 10"8 risk levels
(Figure C).  Seventy of the 87 mills evaluated (80%) were associated with risk levels between 10~5  (32 mills)
to 10"6  (38 mills).

    Using the 30 g/day consumption rate and fish filet contaminant concentrations based on the 50,000 BCF,
mill-specific cancer rates ranged from the  10~1 to 10"7 risk levels (Figure D). Sixty-four of the 87 mills (74%)
were associated with risk levels within the 10"3 to  10^ range, and 41 of these fell within the 10"4 range. Cancer
rate estimates using the 140 g/day fish tissues consumption rate and 50,000 BCF ranged from the  >_ 10'1 to
10"6 risk levels (Figure D). Sixty-three of the 87 mills (72%) were associated with risk levels between the 10"3
and 10"4 range, and 37 of these fell within the 10"3 range.

Cancer Risks Associated with Ingestion of Contaminated Drinking Water

    Figures E and F present the distribution  of the number of mills for which discharges were estimated to
result in a given range of upper bound lifetime cancer risks to the hypotheticaily exposed individual due to
the ingestion of contaminated drinking water. Only those facilities discharging to fresh water lakes, rivers,
and streams were included in this analysis.  No discharges to marine or estuarine waters were included, since
these water bodies would not be used as drinking water sources.

    Use of the simple dilution method estimated that the cancer risks associated with the 69 mills evaluated
ranged from the 10^ to 10'9 risk levels (Figure E). The greatest percentage of these mills (44,  or 64%) were
associated with risk levels within the  10"° (23 mills) to 10  (21 mills) range. Use of the EXAMS II water column
method estimated that the risk levels associated with the 64 mills evaluated would range from the 10'5 to 10~9
levels (Figure F).  Fifty of these mills  (78%) were associated with risk levels between the 10"6 (18 mills) to 10"7
(32 mills) range.

Non-Cancer (Short-Term Exposure) Risks

    Figures G through H present the distribution of the number of mills for which discharges would result in
a given range of human dose due to the single portion consumption of 115 grams of contaminated fish tissue.
The concentrations of fish tissue contaminants used for this assessment were based on a BCF of 50,000 for
2378-TCDD and  1,950 for 2378-TCDF in the edible portion of the fish (the filet).  Results are reported in
pg/kg/day for comparison to a one-day Health Advisory for protection against liver effects (100 pg/kg/day),
estimated by EPA for this investigation.

    Based on the simple dilution method results  (Figure G), the dose associated with discharges from 25 out
of 97 mills evaluated (27%) would equal or exceed the one-day HA dose for protection from liver effects (100
                                               xm

Aquatic Life Impacts

    Aquatic life impacts were estimated based on a comparison of predicted in-stream concentrations of
2378-TCDD and 2378-TCDF (in pg/l) to EPA's preliminary chronic exposure levels for the protection of aquatic
life (0.038 pg/l for 2378-TCDD and 0.41 pg/l for 2378-TCDF). The simple dilution method, using 7Q10 low flow
conditions, predicted that water column concentrations of 2378-TCDD immediately downstream of 80 out of
90 mills (89%) would  exceed  the chronic exposure level of 0.038 pg/l (Figure I). Seventy-four mills (82%)
would exceed the 0.41 pg/l level for 2378-TCDF.

DISCUSSION OF  RESULTS

    The results of this study  indicate  that, taking into consideration the effects of the assumptions and
simplifications used in this analysis, there is a potential for high level contamination  of the water column by
2378-TCDD and 2378-TCDF from the effluent discharges of many of the chlorine-bleaching pulp and paper
mills investigated.  For each of the mills analyzed, use of the simple dilution exposure assessment method
resulted in higher  estimated water column contaminant concentrations and greater estimated aquatic life
impacts and human health risks than the EXAMS II water column method. This is because the simple dilution
method assumes that all contaminants in the water column, both dissolved and adsorbed to suspended solids,
are bioavailable. The EXAMS II water column method, on the other hand, only considers those contaminants
in the dissolved phase. In those cases where the receiving water TSS (total suspended solids) was relatively
low, the simple dilution and  EXAMS II water column results are comparable.  When suspended  solids
concentrations were high, however, the EXAMS II water column method estimated  risks significantly lower
than those predicted by the simple dilution method.  Therefore, for those water bodies included in this study
with relatively high suspended solids content, the EXAMS II water column  method likely underestimated
human health risk from consumption of contaminated fish tissues, since fish exposure to sediment-adsorbed
contaminants was not considered.

    The primary reason for ignoring the exposure routes through contaminated  sediments using EXAMS II
was the lack of acceptable and appropriate fish bioaccumulation factors for this exposure scenario as veil
as the tendency for the contaminants to associate with the very fine sediment fraction which  is  typically
transported and deposited well downstream of the immediate discharge vicinity.  As a check and a sensitivity
comparison on this approach,  however, the results of the simple dilution calculation are considered to provide
an upper bound on fish tissue contaminant levels.

    In addition to the absence of consideration of sediment and food chain exposure routes in the EXAMS II
method, a number of other simplifications and assumptions have influenced the results of this study, including
the selection and  use of BCFs and fish tissue ingestion rates for the evaluation. BCFs are highly variable
depending on the  species, and this study did not take into account inter-species variability in the  rate and
degree of  contaminant bioconcentration. Actual fish  tissue  consumption rates also vary over time, with
individuals, and in different parts of the country.  For example,  risk  estimates based on the 6.5  g/day
consumption rate  and fish filet BCF of 5,000 for 2378-TCDD were established on the basis of EPA's water
quality criteria assumptions. The 6.5 g/day rate applies to a national average consumption rate of fish and
shellfish; however, this rate may not be representative of fish consumption rates for recreational or subsistence
fishermen.  Also, the 50,000 BCF for 2378-TCDD used in conjunction with fish consumption rates of 30 and
140 g/day for recreational and subsistence fishermen was based on the assumption that only the filet portion
of the fish is consumed.  However, some subpopulations of subsistence fishermen and certain ethnic groups
eat whole fish and crabs in which the concentration of contaminants is likely to be higher than in the filet alone.
Therefore, the use of a 50,000 BCF for 2378-TCDD may underestimate risks to these subpopulations.

    It should also  be  noted that, if multiple discharges to the same waterbody are  present, the actual risk
associated with a waterbody may be substantially greater than estimated in this study.  For example, there
are several chlorine-bleaching pulp and paper mills that discharge to the Columbia River basin. Calculations

in this report assume that each mill discharges to a receiving stream with no background level of contamina-
tion. Therefore, in the case of multiple discharges to a receiving stream, estimating risks from one mill alone
can result in a significant underestimate of risk.

    Finally, no assessment of local fish patterns or actual commercial or recreational fishing practices were
conducted as part of this evaluation. Therefore, it is not known whether or not commercially or recreationally
valuable species occur or are taken in the vicinity of the discharges that were included in this evaluation.

    A comparison of predicted cancer versus non-cancer human health risk was also conducted to determine
which of the two end points is the most sensitive. Cancer health risks were estimated to occur for more mills
than non-cancer risks. The results also indicate a potentially greater risk of cancer due to the consumption
of contaminated fish tissue than through the ingestion of contaminated drinking water.  It should be pointed
out that this conclusion may  only be true for the hypothetically exposed individual and may not be true for
the entire exposed population.  Determining which exposure route poses the greatest risk to the entire
population would require knowledge of the number of persons eating contaminated fish tissue versus the
number of persons who use contaminated surface water as a drinking water source. More of the population
would likely be exposed to  a single dose of contaminated fish tissue than  to a lifetime of exposure  to
contaminated fish tissue or  drinking water taken from the vicinity of certain mills. Such a population
assessment was not conducted for this investigation.

    Each of the exposure assessment approaches used in this analysis predict upper bound risks that should
be carefully considered by risk managers while assessing potential impacts associated with the discharge of
2378-TCDD and 2378-TCDF in chlorine-bleaching pulp and paper mill effluents.

Changes  In results for the  International  Paper  Co. mill  In Texarkana, TX (TX000167) have been made based on  comments received from EPA  Region VI.
These comments were received after  the  final  document  had  been  reproduced.

EPA  region VI  indicated  that  this mill  does  not  discharge throughout the entire  year,  but  rather discharges  Intermittently  from  October to Hay.
Therefore, the receiving stream harmonic mean and  7Q10  flows   used  to calculate Instream  concentration (which were based on  a year-round  discharge)
were Incorrect.   The   revised  Tables  C-K  which  follow  present  the  corrected  results  for  the  two  samples taken  from  this  nlll  using the revised
harmonic mean  and  7Q10 flows  (for the tionths  October - Hay) for the receiving  stream.  These changes,  which are  relatively minor,  have not resulted
In  any changes to  the  main  text  of  the  document.

        The present EXAMS II runs were made using an In-stream ISS value of 9.6 ng/1. which li the combined tn-strean and effluent ISS concentration.  This value was used due to the calculation of harmonic
        tean flow for this  mill using the SUM of strew and plant flow.  As described  In Appendix B. Section B.2.2.  of this  report.  If the nil) discharge exceeded SX of the average stream flow at the
        •III. then the Bill discharge flow Mas added to the area-adjusted stream flow values prior to calculating the harmonic scan. During earlier assessments of this islll.  EXAMS II failed to run using
        the  low Instream ISS concentration that resulted from adjustment for annual harmonic mean flow.  For these  runs, an  In-stream ISS concentration based on average annual water flow was used (It

                        POTENTIAL RISKS POSED BY
                     PULP AND PAPER MILL DISCHARGES
                           TO SURFACE WATERS
      EPA recently completed a multi-media risk assessment designed to
estimate  the potential human health and aquatic life impacts caused by
dioxin contamination in surface  water resulting from the manufacture of
chlorine-bleached pulp  and paper.  This summary  of the surface water
portion of the risk  assessment is designed to explain how the study was
conducted, what it  showed, and what  EPA is doing in response  to the
findings.

      What is  Dioxin?

      Dioxin is a general term for  a group of 75 related chemical
compounds. It is an unwanted  by-product created by  the manufacture of
some chemical  products, by certain combustion processes, and by treating
wood pulp with chlorine bleaching  to make white paper.  Dioxin  can
accumulate in  tissue of fish, other wildlife, and humans.  Dioxin has been
shown to cause cancer, liver damage,  and other toxic effects, based on
animal testing.  EPA classifies dioxin as a "probable human carcinogen
(B2)."

      How Was the  Study Done?

      First EPA and the paper industry jointly collected and analyzed
samples of effluent  from each of 104 mills that use  the chlorine bleaching
process to determine the actual concentration of dioxin in the effluent
from the  mills.  With this information,  EPA then estimated the
concentration  of dioxin that might  be found in fish caught downstream of
the paper mills. To make  these estimates, EPA used a number of
assumptions by selecting among a range of scientifically plausible values
for key factors of the  risk assessment.

      For example,  EPA had to  select a bioconcentration factor (BCF),
which represents the number  of times  the concentration of a chemical in
fish exceeds the concentration of that chemical in water.  Since  data
exist to support a range of BCFs,  EPA presents risk estimates using two
different BCFs. EPA also had to estimate such factors as the fate and
transport characteristics of dioxin  in the water environment, the
percentage of  time that fish are exposed to dioxin, and the amount of
fish that the average consumer, or recreational or subsistence level
fisherman, typically consume.

Once EPA estimated  the concentration of dioxin in  the fish caught
downstream of the mills, it then calculated the increase  in lifetime

-------
cancer and non-cancer risks to consumers of fish caught downstream from
the 104 mills.  Risks were estimated for individuals with average fish
consumption rates, as well as for recreational and  subsistence fishers.
EPA also estimated the potential for human liver  toxicity and aquatic
life effects,  as well as effects from consumption of drinking water.

      What Did the Study Show?

      Results of  the  study indicate that there are  potentially high risks
to humans  associated with eating fish caught downstream of a number of
the paper mills.  It estimates that  dioxin levels downstream from some
mills in the study may lead to contamination of fish to a level where
there is an increased risk of average consumers  developing cancer  which
is greater  than one in ten thousand.  The estimated cancer risk is
greater for recreational and subsistence level fisherman because their
estimated consumption of fish is higher than that of average consumers.
Estimates also indicate that dioxin  levels  downstream of five mills may
lead to contamination of fish  to  a level at  which damage to liver  tissue
may occur  after eating a single one-quarter pound meal.   Aquatic life
impacts,  such as aberrations in growth, weight,  and hatching, are
predicted to occur downstream of many of the mills.  Finally,  study
results indicate that  the fish tissue exposure route poses  a greater
human cancer risk than does drinking water to the exposed individual.

      What Does  It Mean?

      Results of  the  study indicate that, over a  lifetime of consumption,
there are potentially high risks associated with eating fish caught
downstream of some chlorine-bleaching pulp and  paper mills.  Currently,
States have issued fish consumption advisories near 22 of  these
particular mills.  In addition, some of the data used in the study are now
two years old,  and States may have more  recent  or comprehensive data
that indicate that discharges from  some of these  mills are not currently
causing the same level of contamination.

      What  are EPA and the States Doing  in Response?

      While there is much uncertainty associated  with the  science of
dioxin and with risk  estimates,  EPA is suggesting that  States  consider
establishing fish  consumption advisories for waterbodies near identified
mills as soon as possible, or  implementing site-specific monitoring
programs to better evaluate  the actual risks at these sites.  In addition
to these actions,  EPA and the States are issuing  permits with  limits to
control dioxin, many of which also include requirements for these mills  to
make  changes that will reduce the  use of chlorine.

      EPA  is also developing new technology-based standards  to reduce
dioxin contamination from manufacture  of bleached  paper products.  In
addition, EPA is  undertaking a  pollution prevention initiative that
involves other Federal Agencies, States,  industry, environmentalists and
the international  regulatory  community.

                DIOXIN RISK ASSESSMENT  ISSUES PAPER
      The scientific basis for EPA's assessment of risks to human health from
emissions  of dioxin has  been  the  source of much  confusion and debate for  some
time now.   Recently, however,  a  number  of  new  developments have placed  the
science in a state  of flux.   The following  is  a  brief discussion of EPA's current
position on some of these  issues,  as well  as  an indication  where  EPA  may  be
headed.
HUMAN HEALTH  EFFECTS
      The  multi-media risk assessment used the same carcinogenic potency factor
used in EPA's 1984 ambient  water quality criteria document:  1.6 X I05
(mg/'kg/day)"1.  Recently this  potency has been questioned as a result of a
reevaluation of the toxicity study results  (rereading of the Kociba slides)
according  to  new  pathological guidelines, which  are  more discriminatory than  past
practices with regard to identifying carcinogenic lesions.   By reducing the overall
numbers of tumors counted in the study, the  rereading  of the slides reduced  the
risk numbers generated from  this data set  by a factor of 3  to 4.

      This result  is consistent with EPA's  earlier  judgment that 2,3,7,8-TCDD
(dioxin) human health risk estimates, based on the animal data, represent
plausible upper bounds on  risk;  true risk is likely to be  less.  The  change
suggested  by the  re-reading of the Kociba  slides  is less  than  an order of
magnitude  and is  within  EPA's  level of  uncertainty;  therefore  it does not warrant
a change in  EPA's potency factor at this time.   EPA will, however, keep  a  close
eye on  the ongoing research,  and may reevaluate  this position in the next 18 to
24 months.   In  the meantime, EPA  does not  plan to change  the potency
estimate in its water  quality  criteria  document.
CANCER  RISK

      In trying  to  estimate concentrations of dioxin in  fish caught downstream of
the mills,   EPA relied on  1988 effluent data in its computer models.  These
estimates were updated with more recent fish  tissue monitoring data provided by
the EPA Regions.  It is important  to  note  that these monitoring data ,are not
included in the  surface water risk assessment report,  but were used  to create
Table 1.

-------
      Table  1  lists sites  where fish sampled in  1986-88 for EPA's National
Bioaccumulation  Study,  or  fish sampled  more recently  by the EPA  Regional
Offices, have concentrations of dioxin  that  arc estimated to pose an  increased
cancer risk as  high as  one in 10,000 to one in  100  for persons consuming these
fish  over  a  lifetime.  The one in  10,000 risk was selected  as  a  possible level of
concern because  it corresponds to a dioxin  concentration that is just below the
level of concern  for non-cancer effects of liver and  reproductive toxicity.   Table I
risk  estimates are based  on EPA's 1984 water quality  criterion  assumptions
regarding  the  dioxin  potency factor and  a fish consumption rate of 6.5 grams per
day  (e.g., two  quarter-pound meals per month).

      Because  of the limited monitoring data on  fish below the 104 mills, the
surface  water risk assessment  for the multi-media study depends on modeling
predictions of dioxin  concentrations that could be expected in the  fish.  Table 2
lists  sites  where a simple dilution  model predicts  that dioxin  concentrations
measured  in  effluent  in  1988 are estimated  to contaminate fish  to  levels that.
with a lifetime of exposure, would  increase  cancer risk  to a range  of  one  in
10,000 to one  in  100.  These risk estimates are  based  on  EPA's water quality
criterion  assumptions  regarding the dioxin potency factor,  a 6.5  grams  per day
fish  consumption rate, and a  bioconcentration factor of 5000  for edible fish
tissue. The bioconcentration factor (BCF)  represents the number of times  the
concentration of  a chemical in fish exceeds  the  concentration  of that chemical in
water.

      Recent studies  have  indicated that  BCFs  may be higher than the 5,000
BCF used in the EPA water  quality criterion for dioxin.   The  most recent work
on a dioxin BCF comes  from EPA's Duluth  laboratory, which estimates
equilibrium BCFs for whole body levels  that may range up to  150,000.
depending on  the species of fish.  For edible fish  tissue, these studies  would
suggest  that a  50,000  BCF may  be  appropriate.   The  Duluth studies  will be
completed and  submitted for peer-reviewed  publication  this fall.   EPA  may give
further guidance  to States on  the  BCF issue  following  this publication.  Table  3,
which is based on the  new evidence regarding a  potentially higher BCF,  is
included  for your consideration.   It  lists sites with a predicted increased cancer
risk  as high as one  in  10,000 to one in  100  based  on   EPA's water quality
criterion  assumptions  regarding a dioxin  potency  factor  nnd its fish  consumption
rate  of 6.5 grams per day, but  uses a 50,000 BCF for edible fish  tissue.
NON-CANCER  HEALTH EFFECTS

      Significant non-cancer human  health effects (in  particular liver and
reproductive effects) from  fish consumption  in  areas just below the  mills  could

-------
also be a cause for concern in certain circumstances.   Based on animal
laboratory studies,  EPA has estimated that  dioxin exposure  should  not exceed
picogram  per kilogram  of body weight per day  to fully protect against  adverse
non-cancer effects.   Using EPA's criteria document assumptions  at  the dioxin
levels associated with a one in 10,000 cancer  risk, dioxin exposure  is calculated
to be below, but very  close  to, the lower end of this  range,  and represents
approximately a doubling  of accepted estimates  of general population exposure
from  all sources.  Children and  pregnant women may  be particularly at risk.
FISH CONSUMPTION RATES

      In many  cases,  the  States and  EPA have  no data on local  fish
consumption rates or dioxin contamination in sediments.  The Office  of Policy,
Planning and Evaluation  (OPPE)  and the Office of Research and  Development
(ORD)  are  currently developing a  methodology  that States  could  use  to identify
exposed populations and estimate  local consumption patterns.  In  the meantime.
States should work  on  their own  procedures  for  estimating  consumption, since
this  is a critical factor  in  determining whether standards adopted  to comply with
Section  303(c)(2)(B)  of  the  Clean  Water  Act are protective  for any chemicals
presenting human  health  risks to  fish consumers.   Next fiscal year, EPA  may be
able to  provide  some contract dollars to  help States estimate local consumption
rates or monitor sediment contamination  below  high risk mills.   The  Office of
Water will be providing further guidance  to  you on this issue in  the  near future.
RELEVANCE OF FOOD  AND DRUG ADMINISTRATION ADVISORY
NUMBERS

      Some States  base  the decision to issue a  fish  consumption  advisory or ban
on  FDA's  chemical  action  levels.  FDA exposure assumptions,  in accordance
with its legislative mandate, reflect  expected consumption by buyers of fish  in
interstate commerce.  FDA generally assumes,  for example, that contaminated
fish would  not constitute a high proportion of such  a consumer's diet.   Fish sold
in interstate commerce comes from  many waterbodies, reducing the  likelihood  that
a consumer will be steadily exposed to  fish taken from  a  watcrbody with high
dioxin  levels.   In contrast,  EPA is  concerned  about  (and the States may  be
obligated under local authorities to  consider) the individual who frequently  fishes
at the  site  or who  regularly eats fish from  the  area.  Thus, the  FDA advisory
number of 25  parts per trillion for  dioxin  in fish would not be sufficiently
protective where individuals  are  consuming more than a few meals  per  year.
The EPA-FDA Standing Committee on Contaminants in Fish  and  Shellfish has
encouraged the use of toxicology and risk  assessment in establishing local sport
fish advisories.

INFORMATION ABOUT MATRIX OF 104  PULP AND PAPER MILLS,  RISK ESTIMATES
            SECTION 304(1) STATUS, FISH ADVISORY STATUS,
                     AND WATER QUALITY STANDARDS.


  For each  of  the 104  chlorine-bleaching pulp and paper mills  (one
  mill  is represented  twice  because  it  has  two  discharge pipes)
  included in EPA's surface water risk assessment the attached matrix
  provides the following information:

  o     A  cancer  risk  estimate for  2,3,7,8-TCDD  (dioxin).    This
       cancer  risk estimate  is  based  on  modeling of  effluent  data
       from  the   EPA/Industry Cooperative 104  Mill Study  using a
       bioconcentration  factor   (BCF)   of  5,000  and   average   fish
       consumption rate of 6.5 grams per day.   These assumptions are
       from EPA's  1984 Water Quality Criteria  Document for  2,3,7,8-
       TCDD.   This information  can  be found  in  Appendix  I of  the
       surface water risk assessment.  It is  the only information in
       this  matrix that  can  be  found in  the surface  water  risk
       assessment.  The risk assessment also  includes several other
       risk estimates based on alternative sets of assumptions.

  o    Whether or  not the mill is  on the list of facilities  required
       by  Section  304(1) (1) (C)   of  the  Clean  Water  Act due  to
       discharges  of dioxin, and the status of the  Individual Control
       Strategy  for  each of  those  facilities.    Section 304(1)
       requires  that States identify those  waters that do  not  meet
       State water quality standards for toxic pollutants  entirely
       or  substantially  due  to  point  source  discharges and  to
       identify  the responsible point  sources.  The State must  then
       write an  individual control strategy  (ICS) for each  of those
       facilities,  and  EPA must approve or  disapprove the  ICS.   An
       ICS is defined as either a draft or final National Pollutant
       Discharge Elimination System  (NPDES)  permit.

  o    Whether  or  not a  fish  consumption  advisory  is   in-place
       downstream  of the mill due to dioxin contamination of fish.

  o    The status of the adoption of the State water  quality  standard
       for  dioxin.  The matrix  includes  values for water  and  fish
       criteria  or fish only criteria or both.   Section 303(c)(2)(B)
       of the Clean Water Act  requires States to adopt water quality
       criteria  for all toxic pollutants of concern in the  State.


  The mills appear in order according  to cancer risk,  starting  with
  the highest cancer risk.

&EPA      Environmental  News
      EPA RELEASES  RISK ESTIMATES  FOR EATING DIOXIN-CONTAMINATED FISH

                              Sean McElheny (202)  382-4387

                                       Monday,  September 24,  1990



           The U.S.  Environmental  Protection Agency today released

      estimates of  lifetime cancer risks, at levels of concern,  for

      consumers of  dioxin-contaminated fish taken from waters down- •

      stream of 20  chlorine-bleaching pulp and paper mills that  dis-

      charge dioxin.

           These mill-by-mill risk estimates are  part of a comprehen-
      sive Dioxin-in-Paper Integrated Risk Assessment.  The Agency
      released a summary of this risk assessment  on April 30, 1990,
      when it announced its plans  to reduce the dioxin risks associated
      with the chlorine-bleaching  pulp and paper  industry.  All  of the
      key findings  in the assessment were included in the summary,
      except for the mill-specific risk numbers announced today.

           The study results are presented as the estimated risk of
      cancer incidence during the  lifetime of the exposed individual.
      For these risk estimates, reasonable worst-case characterizations
      were used. Study results indicate that dioxin levels downstream
      from the 20 mills may be high enough to pose an increased  cancer
      risk greater  than one in 10,000 to average  consumers of fish
      caught below  the mills. The  estimated cancer risk is potentially
      greater for avid sports fishermen and subsistence level fishermen
      because their consumption of fish is generally higher than that
      of average consumers. There  are a total of  104 pulp and paper
      mills that discharge dioxin. (For more information on risks from
      all 104 mills, see attachments.)

           "EPA suggests that states consider imposing fish consumption
      advisories or start site-specific monitoring programs at all
      streams that  have a projected risk as high  as one in ten thousand
      or greater,"  said Deputy EPA Administrator  Henry Habicht.   "These
      risks levels  will come down  as EPA and states impose more  strin-
      gent permit limits and mills reduce dioxin  discharges." (See
      attached list for mills for  which fishing advisories already are
      in place.)

      R-158                       (more)

-------
                               -2-

     States should consider all data available to them in decid-
ing whether fishing advisories or monitoring programs may be
appropriate.

     All risk estimates in the assessment are based on consump-
tion of fish—such as catfish, suckers, squawfish and bass—that
spend their entire lifetime in the vicinity of a mill and conse-
quently accumulate greater concentrations of dioxin in their
tissue.  The risk estimates do not apply to migratory fish, such
as salmon, that spend a short portion of their lives in these
waters.

      EPA and states are issuing, on an expedited basis,  was-
tewater discharge permits that limit dioxin discharges from
chlorine-bleaching pulp and paper mills.  These National  Pol-
lutant Discharge Elimination System permits will ensure that mill
discharges achieve the more stringent of either water-quality-
based effluent limits, or technology-based limits (that is, based
on the capability of existing technology).  Many of these permits
also include requirements for mills to make process changes
and/or product substitutions to reduce the use of chlorine by
certain dates.

     Permits to limit dioxin discharges are being issued  for
about 66 mills on an expedited basis where water quality  problems
due to dioxin have been identified through EPA and state  efforts
to locate toxic hot spots.  Most of these permits will be issued
by February 1991.  Permits for 18 of the 20 mills with projected
risk of one-in-ten thousand or greater are included in this
group.  Under these permits, mills will be required to meet
water-quality-based limits for dioxin no later than June  1993.
Permits for the other two high-risk mills will be revised to
include dioxin limits within the next year.  Permits with dioxin
controls for the remaining chlorine-bleaching pulp and paper
mills will be issued over the next few years as existing  permits
for these mills expire.

     EPA also is developing national industrial effluent  limit
guidelines and standards to reduce dioxin contamination and total
chlorinated organics from the manufacture of bleached paper
products.  These standards, based on the best available,  economi-
cally achievable technologies, are expected to focus on changes
in the bleaching process so as to prevent the formation of
dioxin.  EPA plans to issue proposed standards in 1993 and final
standards in 1995.  These standards will be used in subsequent
rounds of permit revisions for pulp and paper mills and are
expected to reduce dioxin contamination in sludge and pulp as
well as wastewater.

     "The overall risk of dioxin to human health and aquatic

systems requires the precautionary actions we are taking, even
though the scientific basis for estimating dioxin cancer risk and
the mill-based specific risk numbers themselves may be changing,"
said Habicht.

     EPA is proposing a dioxin pollution prevention initiative
that will involve other federal agencies, states, industry,
environmental groups and the international regulatory community.
The purpose of the initiative is to accelerate  pollution reduc-
tion through industrial process modifications and chlorine
substitutes.  Many of the 104 mills already have reduced dioxin
discharges through such changes; some have achieved significant
reductions.  The initiative will include an exchange with Canada,
West Germany, Sweden and other nations of technology transfer
projects and public information efforts.

     The full Dioxin-in-Paper Integrated Risk Assessment is
available.  That document is the result of a cooperative effort
among EPA, the Food and Drug Administration and the Consumer
Product Safety Commission to estimate the risks posed by dioxin
associated with the chlorine-bleaching of pulp and paper.  The
risk assessment was the technical foundation for EPA's April 30
announcement.

     The risk assessment is a scientific support document.  It
estimates dioxin risks from pulp and paper mill effluent, pulp
and paper mill sludge, food contact papers and body contact
papers.  It also includes risks to wildlife and occupational
risks.

     The risk assessment is supported by 12 studies.  The surface
water risk assessment that contains the mill-specific risk
calculations is one of these studies.

INFORMATION ABOUT MATRIX OF 104 PULP AND PAPER MILLS,  RISK ESTIMATES,
            SECTION  304(1) STATUS,  FISH ADVISORY STATUS,
                     AND WATER QUALITY STANDARDS.


   For  each of the 104 chlorine-bleaching pulp and paper mills  (one
   mill  is  represented  twice because  it  has two  discharge pipes)
   included in EPA's surface water risk assessment the attached matrix
   provides the  following  information:

   o     A cancer  risk  estimate for  2,3,7,8-TCDD  (dioxin).   This
       cancer risk estimate  is based  on  modeling of  effluent data
       from the  EPA/Industry  Cooperative 104  Mill Study  using a
       bioconcentration   factor  (BCF)  of  5,000  and   average  fish
       consumption rate of 6.5 grams per day.  These assumptions  are
       from EPA's 1984 Water Quality Criteria Document  for  2,3,7,8-
       TCDD.   This  information can be found in Appendix  I of  the
       surface  water risk assessment.  It is  the only information in
       this matrix  that  can  be  found in  the surface  water risk
       assessment.   The risk assessment also includes  several other
       risk estimates based on  alternative sets of  assumptions.

   o    Whether  or not the mill is on the list of facilities  required
       by  Section  304(1) (1) (C)  of the  Clean  Water  Act due  to
       discharges of dioxin,  and the status of the Individual Control
       Strategy  for  each of   those  facilities.   Section 304(1)*
       requires that States  identify those waters that do  not meet
       State  water quality standards for toxic pollutants  entirely
       or  substantially  due  to  point  source  discharges and  to
       identify the  responsible point  sources.  The State must then
       write  an individual control  strategy  (ICS) for  each  of those
       facilities, and  EPA must approve or disapprove the  ICS.  An
       ICS is defined as  either a draft or final National Pollutant
       Discharge Elimination System (NPDES) permit.

   o    Whether   or  not  a fish consumption  advisory  is   in-place
       downstream of the  mill  due to dioxin contamination of fish.

   o    The status of the adoption of the State water quality  standard
       for dioxin.  The  matrix includes  values for water  and  fish
       criteria or fish only criteria or both.   Section 303(c)(2) (B)
       of the Clean Water Act requires States to adopt  water quality
       criteria for  all toxic  pollutants of concern in the  state.


   The mills appear in order according  to cancer risk,  starting with
   the highest cancer risk.

Changes  In results for the  International Paper Co. mill In  Texarkana,  TX  (TX000167)  have  been  made  based  on comments received  from  EPA Region  VI.
These comments were received after  the final document had been reproduced.

EPA region VI indicated  that this mill  does  not discharge  throughout  the entire year,  but  rather discharges  Intermittently from October to Hay.
Therefore, the receiving stream harmonic mean and 7Q10 flows  used to calculate  Instream concentration (which were based on a year-round discharge)
were Incorrect.   The  revised  Tables  C-K which  follow  present the corrected results for the two samples taken  from  this mill  using the revised
harmonic mean.and  7Q10  flows (for the months October  - Hay)  for the receiving stream.  These  changes,  which  are relatively minor,  have not resulted
in  any changes to  the  main  text  of  the document.
                                                                            Errata Sheet for Table C.I

        The present EXAMS II runs were made using an tn-stream ISS value of 9.6 mg/1. which Is the combined In-streara and effluent TSS concentration.  This value was used due to the calculation of harmonic
        mean flow for this  mill using the sum of  stream and plant flow.  As described In Appendix B, Section B.2.2. of this report. If the mill discharge exceeded SX of the average stream flow at the
        mill, then the mill discharge flow was added to the area-adjusted stream flow values prior to calculating the harmonic mean. During earlier assessments of this mill, EXAMS  II failed to run using
        the  low Instream TSS concentration that resulted from adjustment for annual harmonic mean flow.  For these runs, an In-stream TSS concentration based on average annual water flow was used (22

  U.S. EPA weight-of-the-evldence classification "82" (US EPA.  1986a)

  Recent laboratory evidence Indicates that use of a  BCF of  50.000 would more accurately reflect the uptake of 2378-TCDO by fish.   Therefore,  risk estimates based on a fish filet BCF of 5,000 may underestimate
  risks by an order of magnitude.
