EXECUTIVE SUMMARY
Sitka, Alaska is in the southeastern end of the state. Primary
activities in the area are tourism, fishing and pulp and paper production.
Local citizens are concerned about their exposure to toxic chemicals,
specifically dioxin, which may be released as a result of pulp mill
operations. In response to this concern, the U.S. Environmental Protection
Agency (EPA), in cooperation with Alaska Department of Environmental
Conservation (ADEC) and the U.S. Fish and Wildlife Service (USFWS). conducted
a reconnaissance survey for chemical contaminants in Sitka and the surrounding
areas during August 26-31, 1990.
During June, July and August 1990 the State of Alaska Department of
Environmental Conservation (ADEC) completed an analysis of dioxins and furans
in ash and sludge samples near the pulp mill. Their data are also included in
this evaluation.
The results of the reconnaissance survey for chemical pollutants in the
Sitka area are described in two parts. The first part (Section II) includes
the results of the reconnaissance survey for approximately 250 inorganic and
organic chemicals as well as a detailed discussion of sampling and analytical
methods for dioxins and furans. Measurements of dioxins and furans in
environmental media (ash, sludges and sediments) for which there is no direct
human exposure are also described in the first part. A preliminary risk
assessment for exposure to dioxins and furans by people living in Sitka is
presented in the second part (Section III)
Very low concentrations of dioxins and furans were found in the Sitka
area. At these low concentrations, using worst case exposure assumptions, the
likelihood of health effects occurring is also very low. The analysis
presented in this report is not intended to be considered a formal risk
assessment. The 'results may be used to determine if additional sampling and
analysis are warranted.
The conclusions reached in this report are based on limited sampling of
the following environmental media for dioxins and furans:
1) ash from the APC mill,
2) floating residue in Silver Bay,
3) leachate and sludge from the city landfill,
A) sediment from Silver Bay and Blue Lake,
5) soil from Sitka and surrounding areas.
6) water from Blue Lake, and
7) seafood from Silver Bay, Thimbleberry Lake and Blue Lake.
Trace levels (0 to 22 parts per trillion) of dioxins and furans were
found in floating residue, soils and sediments. These levels appear to be
similar to background concentrations reported for the U.S. and other countries
throughout the world. No dioxins or furans were found in leachate from the
landfill and water from Blue Lake. The highest levels were found in ash from
the pulp mill power boilers. High concentrations of dioxins and furans in ash
-------

from incinerators have been previously documented in other municipal and
industrial settings.
Seafood from Silver Bay also contained trace levels of dioxins and
furans. The range in concentration from (0 to 3 parts per trillion) is
similar to other background levels measured in the U.S.
The results of the reconnaissance survey for other potential pollutants
in the Sitka area are summarized below:
The degradation of water quality, demonstrated in previous
studies. continues. Dissolved oxygen at depth was below levels
considered adequate to support marine life. pH was below normal
levels in surface waters. Organic material on the seafloor was
built up considerably over pre-discharge levels. This blanket of
solids depletes oxygen in sediments and bottom water, greatly
affecting benthic organisms. Suspended solids and color in the
upper water column can reduce photosynthesis adding further stress
to the marine ecosystem.
Sediments, water and soils were sampled for the presence of more
than 250 inorganic and organic chemicals. Several contaminants
found in the sediments and water of Silver Bay may be a threat to
the health of the aquatic organisms. Based on a comparison with
values used to assess marine sediments in Puget Sound, Washington,
4-methylphenol, benzoic acid, and phenol may affect the aquatic
organisms which live in the sediments. Copper and zinc in Silver
Bay exceeded EPA's ambient water quality criteria for marine life.

II. RECONNAISSANCE SURVEY
A. Methods
1. Sampling
The sampling objectives were to: (1) evaluate the potential
accumulation of dioxins and furans and metals in air emissions from the Alaska
Pulp Corporation pulp mill (APC) into surface soils, Thimbleberry Lake fish,
and Blue Lake water, fish, and sediment; (2) evaluate the presence of dioxins
and furans, metals, and organic contaminants in the marine environment near
the APC effluent discharge (for this study, marine sediments and biota were
examined for dioxins and furans, but water column samples were not); and (3)
evaluate the presence of dioxins and furans and metals in the City landfill
and potential release of these contaminants from the landfill by sampling the
ash at APC and sampling leachate and sludge at the City landfill. Table 1
summarizes details about the samples collected and lists the general types of
contaminants that were evaluated.
Field Sampling
Marine sampling and freshwater sampling were conducted with the
assistance of the USFWS. The vessel Curlew was used to occupy sampling
stations and conduct the trawl as described below. A skiff was used to deploy
and retrieve gill nets, set lines, and crab pots. An inflatable boat was used
to collect samples at .Blue Lake.
Marine Sampling
Water: Locations were chosen to (1) reflect increased distance from APC, (2)
be within close proximity (less than 2.5 miles) to APC, (3) sample in Silver
Bay as well as Eastern Channel, and (4) sample near or in Sawmill Cove. Based
on vessel operation considerations, stations were occupied where water depth
was approximately 60 meters. Four stations were occupied, one in Thimbleberry
Bay (Station 1, off of Eastern Channel) and three in Silver Bay (Station 2, in
the western arm of Silver Bay, between Sawmill Cove and Eastern Channel;
Station 3, at the entrance to Sawmill Cove; and Station 4, near the southern
point of the entrance to Herring Cove). The four stations are named for
nearby water bodies; their locations are shown in Figure 1. Approximate
station locations were plotted using distances and relative compass bearings
indicated on the Curlew's radar. Sampling dates and times are in Appendix C-
4, Table 1.
A Hydrolab unit was used to measure depth (m), temperature (°C), pH, and
dissolved oxygen (mg/L-uncorrected). The unit was calibrated in the morning
and evening each day it was used. Because this particular unit was not
configured to measure conductivity in seawater, salinity was estimated based
on surface, mid-depth, and bottom grab samples analyzed by use of a
refractometer at the EPA Region 10 lab.

At each station, surface, mid-depth, and bottom grab samples were
composited. A brass Kemmerer sampler and a PVC Kemmerer sampler were used to
collect samples for organics and metals analyses (respectively). Collection
containers were filled one third from each grab, except for samples destined
for volatile organics analysis (VGA). For VOAs, separate containers were
filled from each grab. These were later combined at the EPA Region 10 lab to
produce a composite sample prior to analysis. A few drops of acid were added
to the VOA samples. Water samples were provided to USFWS for their use in
conducting bioassays. Each Kemmerer sampler was rinsed with methylene
chloride and then distilled water between uses.
Sediment: A stainless-steel, 0.1-m2 Van Veen sampler was used to collect
marine sediments. A maximum of 10 attempts was made at each of the stations
to obtain 4 acceptable grabs. Despite problems such as failure of the sampler
to trip, washout due to wood, rocks, or trash in the jaws, canted sample,
shallow penetration, etc., grabs were collected successfully at 3 of the
stations (at Thimbleberry Bay. no successful samples were obtained within 10
attempts due to the rocky substrate). At these three stations a single
sediment sample was obtained by compositing subsamples from separate grabs.
The sediment VOA samples were collected from the first successful grab except
for the Eastern Channel Sample in the western arm of Silver Bay. when a
composite was used. All traces of sediment were rinsed from the Van Veen
sampler using ambient seawater prior to each successive grab attempt. At each
site, a new, cleaned (and previously foil-wrapped) stainless steel spoon was
used to transfer and mix sediments.
Tissue: Set lines, gill nets, crab pots, pole and line, a bottom trawl, and
collection by hand in the intertidal were used to obtain organisms for tissue
analysis. The sampling sites (Figure 1) were located within the vicinity of
APC and the water and sediment sampling stations. Organisms were identified,
measured, weighed, and evaluated for external evidence of problems such as
lesions or tumors. Next, in accordance with the protocols established for the
National Bioaccumulation Study (USEPA 1989), they were wrapped in foil and
frozen. Mussels were collected from the intertidal into a glass jar and then
frozen.
A variety of marine organisms was caught. Shrimp (mixed), mussels and
crabs were the shellfish selected for analysis. Crab hepatopancreas and the
remainder of the crab body were analyzed separately. In consultation with
NOAA personnel familiar with the effects of sediment contamination on fish as
well as fish life histories (Long 1990), Pacific sanddab, English sole, and
Pacific staghorn sculpin were selected for analysis. Quillback rockfish were
collected from 3 of the 4 marine sampling stations; these were analyzed to
investigate the variability in tissue contamination across stations.
Freshwater Sampling
Water: A water sample was obtained August 30, 1990, at the Water Treatment
Plant northwest of APC. Water from Blue Lake is piped down to the plant.
Sample jars were filled directly from the pressure relief valve.
-------
RNAL DOCUMENT - Silka. AK; August 1990 Survey Page - 9 -
Sediment: A sample of sediment at Blue Lake was collected on August 30, 1990,
by compositing grab samples from two locations (approximately 150 ft water
depth on the west side of the lake and 50 ft water depth on the east side) ,
using a Petite Ponar grab sampler, deployed 100 ft from shore (Figure 1).
Tissue: Minnow traps were used to collect fish "from Thimbleberry Lake and
Blue Lake (Figure 1). Fish were identified, measured, weighed, and evaluated
for external evidence of problems such as lesions or tumors. In accordance
with the protocols established.for the National Bioaccumulation Study (USEPA
1989) , fish were wrapped in foil and frozen. Rainbow trout from Blue Lake and
Eastern brook trout from Thimbleberry Lake were submitted for analysis.
Soil Sampling
Preliminary sampling locations that were identified included day care
facilities, schools, playgrounds, residences, and areas potentially in the
path of air emissions from APC, recognizing the possible confounding influence
of the Sitka City incinerator. Final locations were chosen based on a survey,
August 29, 1990, of Sitka, Japonski Island, and areas in vicinity of the road
leading from town to APC. A reference location, assumed to be away from the
influence of APC or City emissions was selected at the head of Deep Inlet. As
shown in Appendix C-6 and Figures 2 and 3, at each of 10 locations, composite
samples of four aliquots (5 at Deep Inlet) were collected for analysis. A
field replicate was collected at APC. At each location, a new, cleaned (and
previously wrapped) stainless steel spoon was used to transfer soils from the
top 0.5 to 1 inch into collection jars. The field replicate was collected by
spooning soil into two sets of jars.
Landfill Sampling
At the landfill (Figure 2), on August 31, 1990, samples of leachate and
sludge were collected from the catch basin. A field transfer blank sample
(transferring distilled water to containers while on site) was also collected.
The leachate water was collected by dipping a glass 1 gal jar into the
catch basin then filling the sample jars from this grab. The "sludge" that
had collected in the bottom of the basin was scooped out with a stainless
steel spoon. Each scoop was apportioned among the sample jars. No acid was
added to the sediment VOAs.
APC Ash Sampling
Ash samples were collected in the power house (Figure 3). Bottom ash
was collected from the power boilers. The power boilers produce ash which
remains at the bottom of the boiler on the first floor of the power house.
This ash is raked into dumpsters. A composite, representative sample of power
boiler bottom ash was scooped out of the hoppers using a wooden spatula. On
the third floor of the power house, exhaust from the boilers passes through
multiclones which connect the power boilers with the electrostatic

precipitator (ESP). The multiclones remove large particles of ash which drop
down into a wet whirler. The remaining boiler exhaust continues to the ESP
where fly ash is removed (fly ash was not sampled) . A composite sample of the
multiclone ash was obtained by APC personnel who held a jar through the
observation ports and collected the ash as it fell down from the multiclone,
before it reached the wet whirler.
Quality Assurance/Quality Control
A QA plan was developed for this sampling effort (Appendix D) . In the
field, two QA samples were collected: A field duplicate sample for the soil
sampling conducted at APC; and a field transfer sample obtained when sampling
at the City landfill catch basin.
Laboratory QA procedures involved matrix spikes, duplicates, and blanks.
These were analyzed to provide information on analytical reliability and
variability and to qualify data when necessary.
Other Contemporaneous Sampling
The Alaska Department of Environmental Conservation (ADEC) collected
samples of floating residue from Silver Bay and Eastern Channel and fly ash
samples from the mill (ENSECO 1990, 1991). The power'boiler fly ash samples
were collected June 21, 1990, from the location where the electrostatic
precipitator conveyor screw drops the fly ash into collection bags. AIL
grab sample was collected at the end of each of three 8 hr periods for a total
of 3 samples.
Five grabs of floating residue were collected July 20. 1990 (3 samples
within 100 ft of the log booms and 2 samples near the log pullout area in
Sawmill Cove) and composited for a single analysis of residue in Sawmill Cove.
Two additional residue samples were collected August 8, 1990. from Eastern
Channel (one near the east end of Thimbleberry Bay and one from the midpoint
of Eastern Channel, south of the west end of Jamestown Bay).
During the present survey, the US Fish and Wildlife Service (USFWS)
obtained water samples from the four marine stations occupied in the present
survey as well as floating residue from Sawmill Cove.
2. Analysis
Analyses were completed by US EPA Region 10, Region 7, and Duluth labs.
as well as contract labs (Table 1) . As indicated in Table 1, in addition to
dioxins and furans, analyses for selected samples included metals, organics
(volatiles, semivolatiles, base, neutral, acid compounds, etc.), organic
carbon content, sediment particle size, and salinity. The methods used by
each laboratory are listed or referenced in Appendix D.

B. Results and Discussion
Measured concentrations were compared with a variety of screening
values. These screening values consisted of the EPA ambient water quality
criteria (for freshwater, leachate, and marine water samples), apparent
effects thresholds (for Puget Sound, WA, sediments), and New York Department
of Environmental Conservation screening level (for dioxins in fish tissue).
The results of concern include: (1) Dioxins and furans were present in
sediments, fish, and shellfish in Silver Bay. These contaminants appear to be
at low levels, but their presence in the benthic food web is unknown; (2)
Dioxins and furans were found in Blue Lake sediment in concentrations as high
as in Sawmill Cove. Again, it is not known whether these contaminants are in
the limnetic food web; (3) Four-methylphenol, benzoic acid, and phenol were
present at high levels of concern in the sediments near the mill; (4) Copper
and zinc were present at high levels of concern in the water column near the
mill; (5) Copper was present at high levels in the Herring Cove hogfuel
storage leachate; (6) Dissolved oxygen was depressed below levels considered
to be adequate to support marine life; (7) pH was depressed in surface waters;
and (8) Organic material has built up, possibly beyond levels measured in
1970.
In addition to those stresses listed above, suspended solids and color
reduce photosynthesis in the upper water column and thereby impact the marine
ecosystem.
1. Dioxins and Furans (Appendices A, C-l)
Marine Sediment: In general, the highest values were found in the Sawmill
Cove sediment where more congeners were detected than at the other two
stations. Without some screening value against which to compare the measured
concentration, it can only be stressed here that these compounds are present
in most of the organisms sampled in Silver Bay which is consistent with the
known ability of dioxins and furans to bioaccumulate and enter the food web
(see, for example. Rabert 1990).
Marine Tissue: Dioxins and furans were measured and detected in the tissues
of a variety of fish and shellfish. The following discussion is based on the
review of the effects of tetrachlorodibenzodioxin (TCDD) and tetrachloro-
dibenzofuran (TCDF) releases from pulp and paper mills on aquatic organisms by
Rabert (1990). Lethality has not been shown to be related to TCDD body
burdens in fish. In fact, fish mortality can occur even after significant
loss of TCDD from tissues. However, fish are very sensitive to TCDD and TCDF
and delayed lethality can result from exposures as short as 6 hours. In
addition, fish may develop lesions following exposure. In the present study,
the only evidence of visible external abnormalities found was fin damage in of
4 of 6 total copper rockfish collected from Herring Cove and a growth in the
lower eye of one arrowtooth flounder collected from Thimbleberry Bay. Further
investigation is necessary to determine the cause of these abnormalities.
-------
FINAL DOCUMENT - Sitka, AK: August 1990 Survey Page - 14 -
Because chlorinated dioxins and furans can bioconcentrate, piscivorous
birds and mammals may be at risk. Rabert (1990) cites Newell, 1987,
concerning the New York Department of Environmental Conservation's screening
value. They (NYDEC) determined that wildlife are at risk when feeding on fish
with body burdens greater than 3 pptr (ng/kg) TCDD. In the present study, the
highest TCDD value in tissue was the analysis of English sole at 1.17 ng/kg
which is below the NY screening value. The preliminary data collected during
this survey suggest that wildlife may not be at risk from TCDD when feeding on
fish from the Silver Bay and Eastern Channel areas, at least for those fish
species which were evaluated.
Freshwater: Dioxins and furans were not detected in leachate or freshwater.
Lake Sediment: Dioxins and furans were found in the Blue Lake sediment
sample. The levels of these contaminants were similar to those found in
Sawmill Cove and, apart from the heptadioxins and tetrafurans, were higher
than Sawmill Cove values. There is concern that dioxins and furans may be in
the food web, although they were not in the rainbow trout in concentrations
sufficient to be detected by the laboratory analysis.
Lake Tissue: Based on the laboratory detection limits, dioxin and furan
congeners (containing chlorine at positions 2,3,7,8) were not detected in Blue
Lake rainbow trout or in Thimbleberry Lake brook trout (whole body analyses).
Detection limits, however, were higher than the NYDEC screening value so that
risk to piscivorous wildlife could not be evaluated.
Soil. Ash, and Landfill Sludge Sampling: Because of the emphasis on human
exposure (locations were playgrounds, ball fields, residences, catch basins,
etc.), these sample results are not very useful in evaluating ecological
effects. Dioxins and furans were detected in the ash samples, the landfill
sludge sample, and many of the soil samples (see Section III). The sludge and
soil levels were very low compared with the fly ash. At Deep Inlet, the
background site, dioxins and furans were not detected. However, interference
due to high levels of organic matter resulted in fairly high detection limits.
2. Drganics (Appendix C-2)
Marine water: Analyses for organic compounds were made on composite water
samples from the four marine stations. In general, only a few compounds were
detected. For most of the organic compounds, especially those volatiles and
semivolatiles detected, there are no water quality criteria to use as a
screening tool to evaluate the potential risk to the ecosystem.
Marine Sediment: Because no contaminant-specific marine sediment standards
are available for the state of Alaska, apparent effects threshold values
(AETs), as described below, were used. Bioassays are often used to evaluate
sediment toxicity relative to control or reference sediments. By measuring
contaminant concentrations for the same sediments, it is possible to derive
AETs. These values represent contaminant concentrations above which
biological effects are always observed. An AET is developed for each effect;
increased oyster larvae mortality, or decreased bacterial luminescence, for
-------
FINAL DOCUMENT - Sitka, AtC August 1990 Survey
Page - 15 -
example. The range of AETs can be used then to determine a High AET (HAET)
and a Low AET (LAET) . AETs have been established for Puget Sound, WA, and
these are used to evaluate the Silver Bay sediments. Although these two
waterbodies cannot be considered to have exactly the same biota, they do share
many genera and species (compare information in Barnes, et al. 1956 and
Eldridge, et al. 1957 with Gotshall & Laurent 1980 and Kozloff 1983). Table 2
summarizes the exceedances based upon Puget Sound, WA, AETs.
At the Sawmill Cove station, six contaminants exceeded the AETs. In
particular, 4-Methylphenol was 50 times the concentration set for the HAET and
270 that set for the LAET. Benzoic acid was 16 times the HAET. Phenol was 11
times the HAET and 31 times the LAET. For three other contaminants, the LAETs
but not the HAETs were exceeded (fluoranthene, fluorene, and phenanthrene).
The only other station to show exceedances was Eastern Channel, for 4-
Methylphenol and benzoic acid.

Freshwater; Leachate from the City landfill and water from Blue Lake were
evaluated against the EPA freshwater water quality criteria. Leachate from
the hogfuel storage at Herring Cove was evaluated using EPA marine water
quality criteria since it discharges into Silver Bay. In general, few
organics were detected. For the volatiles and semivolatiles, few EPA
freshwater criteria are available.
Lake Sediment: No standards (AETs or criteria) are available at present for
screening analysis of freshwater sediments.
3. Metals (Appendix C-3)
Marine Water: Analyses for metals were made on composite water samples from
the four marine stations. In general, only a few metals were detected. Some
metals exceeded EPA water quality criteria for aquatic organisms, with the
largest exceedances at the Sawmill Cove station (Table 2).
Copper. Copper was about 60 times the EPA acute (which is the same as
the chronic or continuous exposure) criterion (181 ug/L compared to the
criterion of 2.9 ug/L) at the Sawmill Cove station and about 6 times the EPA
acute criterion at the Herring Cove station. Copper was 2.3 ug/L at the
Eastern Channel station and not detected at the Thimbleberry Bay station.
Zinc. The concentration at the Sawmill Cove station (267 ug/L) was
about 3 times the EPA acute criterion of 95 ug/L. Zinc was 25 ug/L at Herring
Cove and not detected at the other two stations.
Other Metals. Mercury concentrations at the Herring Cove and East
Channel stations exceeded the EPA chronic (continuous) criterion but not the
acute criterion. Similarly, lead concentrations at Herring Cove and
Thimbleberry Bay exceeded the EPA chronic criterion (Table 2).
Marine Sediment: No metals were detected at concentrations exceeding the
Puget Sound AETs.
Freshwater: Blue Lake water had no exceedances of water quality criteria.
The Sitka City landfill leachate, however, exceeded the freshwater acute
criterion for zinc (by 1.25 x) and the chronic criterion for iron (77 x) and
lead (just exceeded; Table 2). Because the leachate commingles with other
waste streams prior to treatment and eventual discharge these results indicate
the probable low toxicity of the leachate rather than a potential effect on
biota. The leachate from the Herring Cove hogfuel storage area exceeded the
marine chronic criterion for copper (4.7 x; Table 2). The volume of discharge
and dilution of the leachate within Herring Cove is unknown, but the marine
copper criterion was exceeded in Silver Bay at the Herring Cove station. This
suggests that effects of copper in Silver Bay should be investigated further.
Lake Sediment: No freshwater sediment criteria are available at present for
screening analysis.

4. Conventionals: pH, DO. T, TOG, and Grain Size (Appendix C-4)
Marine Water: Figures 4-6 show the profiles of dissolved oxygen (DO),
temperature (T, in °C) , and pH. Salinities were lower in the surface grabs
(approximately 20 to 26 °/oo. with mid and bottom grabs having similar values
(approximately 32 °/°o; Appendix C4-Table 1). Salinity and temperature were
used to evaluate percent oxygen saturation (Figure 4). The DO. T, and pH
profiles show: (1) A reduction in DO from 5-9.5 mg/L in the surface to 1.5
3.5 mg/L at 60 m with most of the reduction occurring below 40 m water depth
(changes in % saturation of DO follow a similar pattern) ; (2) A gradual
decline of T with depth; and (3) A depression of pH in the surface 20 m (about
1.8 units below the fairly constant pH of 7.4 measured from 20 to 60 m water
depth). The pH depression was most noticeable at the Herring Cove station.
pH. -- Near surface pH depressions in an August 26, 1965. survey by the
US Dept of Interior (USDOI 1966) was attributed to "the combined result of
biochemical waste decomposition, acid nature of the pulp mill wastes, and
reduced photosynthetic production in the waste layer." However, during the
1965 survey, pH depressions did not fall below 7 units. In our study, pH
below 7 was measured at the surface at 3 of the four stations, and did reach a
low of 5.5 units (Figure 6). One anomalously high reading was noted at 50 m
water depth for the Thimbleberry Bay station.
Dissolved Oxygen. Several previous studies in the Silver Bay area
measured DO. Two studies that preceded the operation of the mill generally
found DO to be above 6 mg/L from the surface to 60 m water depth. In May and
July of 1956, a University of Washington study measured DO values from 6.37 to
11.20 mg/L at water depths of 50 to 75 m regardless of location (Barnes, et
al. 1956). This same study did measure DO as low as 0.5 mg/L, but these
values were in water deeper than 1,300 m. The Alaska Water Pollution Control
Board measured DO in July, August, September, and October, 1956 (Eldridge
1957) . At 30 m, the maximum depth sampled, the lowest DO measured at any
location was 6.7 mg/L. In the surface 0.5 to 1.5 m, DO was always greater
than 8.5 mg/L, apart from a single measurement of 2.6 mg/L measured at 5 ft
water depth (in this instance, DO was 9.4 mg/L at the 2 ft water depth and 9.6
mg/L at 15 ft).
After the mill began operating, DO was again measured on August 26, 1965
(USDOI 1966). Low DO concentrations (4.4 to 7.1 mg/L) were measured in
surface water. DO then increased rapidly to a maximum value at a depth
between 2 and 10 m (maximum values ranges from 7.2 to 8.0 mg/L). Below this,
DO gradually decreased with depth. At 60 m water depth, DO ranged from 3.9 to
5.8 mg/L. According to the U.S. Dept of Interior (USDOI 1966), up-welled
oxygen-deficient ocean water is present in bays and inlets along the north
Pacific coast in late summer. This water can have DO concentrations below 5
mg/L in the absence of any detectable mill discharges. Within Silver Bay, the
extreme oxygen deficit at depth is attributable to oxygen depletion due to
mill discharges exacerbating the low DO found in the up-welled oceanic water
(USDOI 1966). This previous study also suggested that "Any reduction of
dissolved oxygen beyond that observed ... in the surface waters of Silver Bay
will definitely place the values below recommended minimum levels." The

present study did measure values below the 5 mg/L originally recommended in
the 1956 studies as adequate to protect marine life.
Another study in 1968-70 (USEPA 1971) reported considerable reductions
in DO in the surface layers of Silver Bay and Eastern Channel compared with
the level measured prior to operation of the mill. The 1971 EPA report
generally found DO to be above 5 mg/L (apart from some measurements in August,
1970, when DO varied between 4.6 and 6.7 mg/L at a depth of 1 m) . The present
study found DO in surface waters was reduced by approximately 2.5 to 11 mg/L
below pre-mill measurements reported by Eldridge et al. (1957) and Barnes et
al. (1956).
Marine Sediment: Total Organic Carbon (TOG) and Particle Size Analysis
(Appendix C-4 - Table 2). TOC was 30% at the Sawmill Cove station, decreasing
both in Herring Cove (17.5%) and Eastern Channel (8.2%). The 1956 studies
measured organic carbon in Sawmill Cove at 3%, near Herring Cove at
approximately 6.6%, and near our Eastern Channel station at 8.4%. In August,
1970, at three stations in Sawmill Cove, organic carbon was measured at 40%,
30%, and 27%, with increasing distance from the mill (USEPA 1971). Such a
change in organic carbon in Sawmill Cove as noted in 1970 and 1990 indicates a
major deposition of organic matter since the mill began discharging. The
present Sawmill Cove station had an average of 28% TOC. Because it was
located farther from the mill than the 1970 stations, this may indicate an
increase in organic content of bottom sediments or an increase in the area
affected. Comparison of the particle sizes further demonstrates the large
difference, in bottom type among the stations. Approximately 53% of the total
weight of the sediment at Sawmill Cove was in the silt-clay fraction, while
69% was silt-clay at Herring Cove with just 11% at Eastern Channel.
Lake Sediment: The particle size and organic carbon analyses (95% silt-clay
and 2.7% TOC; Appendix C-4 - Table 2) were consistent with a fine sediment
lake bed.
5. Other Contemporaneous Studies
The results of dioxin and furan analysis of the ADEC ash and floating
residue samples were reviewed by EPA Region 10, for quality assurance. These
data are discussed in Section III (see Table 4 and Appendix A for summary
data). In general, -the fly ash samples had the greatest concentrations of
dioxins and furans of all samples analyzed by EPA or ADEC. The floating
residue samples had lower concentrations, but did contain TCDD, which was not
detected in any of the EPA sediment samples. No consistent pattern was seen
in relative proportions of the different dioxin and furan congeners when
comparing sediment and sludge samples. How fish and wildlife come in contact
with floating residue is unknown.
Effects of the residue on biota in Silver Bay and Eastern Channel should
be assessed further. In addition to the dioxins and furans, the ADEC found
metals in the residue. Furthermore, the results of the bioassay conducted by
USFWS using marine bacteria indicated that filtrate from one of two floating
residue samples was highly toxic (USDOI 1990).

III. SCREENING HUMAN HEALTH RISK ASSESSMENT
FOR EXPOSURE TO DIOXINS AND FURANS
Introduction
The screening risk assessment for exposure to dioxins and furans in
surface soils, floating residue, fish, shellfish and crabs is presented in
this section. Section II includes the results of the reconnaissance survey
for all contaminants as well as a more detailed discussion of sampling and
analytical methods for dioxins and furans. Measurements of dioxins and furans
in environmental media (ash, sludges and sediments) for which there is no
direct human exposure are also described-in Section II.
The-risk analysis presented in this report is not intended to be
considered as a formal risk assessment. Extremely conservative exposure
assumptions were chosen as screening tools. These do not reflect actual
exposures which may occur in Sitka. The results of this analysis should be
used to determine what further studies or actions could be taken to protect
public health in Sitka. Before additional sampling or analysis is done, the
assumptions (seafood consumption rate, etc) used in screening assessment
should be revised to reflect actual exposures which may occur in Sitka.
Exposure to dioxins and furans may result in cancer, reproductive and
developmental effects. The chance of developing disease is dependent upon the
concentration of the chemical and the likelihood of coming into contact with
material contaminated with these chemicals. Risks for individuals (children
and adults) who live in Sitka for 30 years in contact with surface soils,
water, floating residue and consuming fish, shellfish and crabs (for 75 years)
is a concern because of potential health effects.
There are a number of uncertainties which may cause the risk estimates
to be too high or too low. Some of these uncertainties are listed below.
- only dioxins and furans were measured in seafood, thus the overall
risks are not addressed
- samples were collected during the summer; concentrations may vary over
time.
- dioxin levels being discharged have been and continue to be reduced,
thus the concentrations in the environment should be diminishing over time
- the toxicity of dioxins and furans is being re-evaluated
- a limited number of samples in presumably worst case areas were
sampled; these may not be representative of the whole community
the seafood (bottom fish, crabs and mussels) collected in Silver Bay
may not be part of the regular sport fishing catch
-------
FINAL DOCUMENT - Sitka, AK: August 1990 Survey Page - 23 -
- there are no data regarding what happens to the chemicals when seafood
is cooked
- exposures are assumed to occur over a lifetime (30-75 years)
- the toxic equivalent concentrations reported here include measured
values as well as a correction for chemical analytical error; 1/2 the
detection limit for some of the 12 toxic dioxins and furans was assumed to be
present
In order to be protective of public health, EPA uses conservative
assumptions for risk assessment. Given these conservative assumptions, the
risks may range from the upper bound estimates given in this report to zero.
Toxicity of Dioxins and Furans
Polychlorinated dibenzo-p-dioxins and -furans are a group of 210
synthetic compounds commonly referred to as dioxins and furans. This complex
group of chemicals are subdivided into homologous groups which are identified
by the degree of chlorination:
(4 Chlorines) tetrachlorodibenzodioxin - TCDD, and
tetrachlorodibenzofuran - TCDF
(5 Chlorines) pentachlorodibenzodioxin PCDD, and
pentachlorodibenzofuran - PCDF
(6 Chlorines) hexachlorodibenzodioxin - HxCDD. and
hexachlorodibenzofuran - HxCDF
(7 Chlorines) heptachlorodibenzodioxin - HpCDD, and
heptachlorodibenzofuran - HpCDF
(8 Chlorines) octachlorodibenzodioxin - OCDD, and
octachlorodibenzofuran - OCDF
Within the groups of homologues there are individual isomers which are
identified according to the location of the chlorine atom on the dioxin or
furan molecule, e.g. 2,3,7,8 tetrachlorodibenzo dioxin (2,3,7.8 TCDD). The
most toxic dioxin or furan compound is 2,3,7.8 tetrachlorodibenzo-p-dioxin
(TCDD). In order to simplify the estimates of risks to human health, a
relative ranking of 12 individual congeners (homologues with chlorine atoms at
the 2,3,7,8 positions) which constitute the class dioxins and furans was
completed. In this ranking system, (Table 3), TCDD is given a rank of one;
the other 11 in these classes are ranked from 0.5 to 0.001 relative to TCDD.

Dioxin and furans can produce a variety of effects including cancer and
reproductive effects in laboratory animals at very low doses (USEPA 1989a).
Based on the results in animal studies EPA has classified 2,3,7,8 TCDD as a
B2 carcinogen or probable human carcinogen. It is the most potent animal
carcinogen (cancer slope factor of 1.56 x 10* per milligram of dioxins and
furans per kilogram body weight per day) evaluated to date by EPA. Recent
reports (Fingerhut et al. 1991) suggest that while cancer has been observed in
humans exposed to relatively high doses of dioxin, dioxins and furans are less
potent in humans than in animals.
In addition to causing cancer, exposures to dioxins and furans may also
result in developmental and reproductive effects. Based on laboratory studies
with animals a one day and lifetime health advisories have been established
through the EPA Drinking Water Program (USEPA, 1988) for these non-cancer
health effects. In order to be absolutely sure of protecting public health,
these advisories are set well above the level which has resulted in adverse
health effects in laboratory animals. Although these health advisories were
primarily developed for the protection of public drinking water, the same
advisories may be used for other environmental media (soils, seafood, etc).
The one day health advisory is: 100 picograms per kilogram-body weight per
day. For a 14 kg (31 pounds) child, a concentration of 7 picograms of dioxins
or furans would be equivalent to the one day advisory. The lifetime health
advisory is 1 picogram per kilgram-body weight per day.
EPA as well as other world-wide health agencies are reviewing the
toxicity data for dioxins and furans. This may result in a change in the
cancer potency estimates and the drinking water health advisories. However,
until this evaluation is complete, risk estimates completed by EPA will
continue to rely on the existing cancer potency factor and non- cancer health
advisories.
Dioxin and Furan Sampling and Analysis
The sampling objectives were to evaluate the potential accumulation of
dioxins and furans in surface soils, fish, shellfish and crabs to which people
may be exposed. The absolute levels of dioxins and furans are presented in
Appendix C-l in this report. For the purpose of discussing risks to human
health, the absolute dioxin and furan concentrations found in all media are
converted to toxic equivalent concentrations.

Soil. Ash, and Landfill Sludge and Leachate. Dioxins and furans were
detected in the ash samples, the landfill sludge sample, and many of the soil
samples. The sludge and soil levels were very low compared with the fly ash
(Tables 4 and 5). No dioxins or furans were detected in the leachate samples
(Appendix A). Detailed discussion of sampling and analysis is provided in
Section II. The high ash level is within the range found in other incinerator
residues (Table 4). Since, people are not expected to encounter ash from
Alaska Pulp Corporation incinerator operations, landfill sludge, landfill
leachate or sediments during regular activities at work, at home or during
recreation, risk estimates are therefore not calculated for direct contact
with these media.

areas where people may come into contact with soils: day care facilities.
schools, playgrounds, public walkways, and private residences (Figure 3).
The toxic equivalent concentrations shown in Table 5 represent not
only what was measured in the soil, but they also include an additional amount
to correct for uncertainty in chemical analytical methods. The measured
concentrations of toxic dioxins and furans ranged from 0.2 parts per trillion
at to 2.6 parts per trillion. When the correction (1/2 detection limit) for
analytical error is included trace concentrations (non-detect to 14 parts per
trillion) of dioxins and furans were found in surface soils in Sitka (Table
5). At Deep Inlet, which was chosen as the local background soil site.
dioxins and furans were not detected. However, interference due to high
organic matter in the sample resulted in fairly high detection limits. There
was no significant difference in concentrations at the various locations
sampled. The levels found in Sitka and surrounding areas were similar to
background levels.

Sediment?Marine and freshwater sediment levels were generally low
(Table 6) ranging from 4 to 12 ng/Kg. While there were not enough samples
taken to establish any significant difference between sites, Sawmill Cove
sediment levels appeared to be higher than other sediments in Silver Bay or
Blue Lake.
Floating residue. Floating residue (fibers, organic matter) was sampled
by ADEC in July and October 1990. The levels of dioxins and furans were
relatively high when compared to concentrations found in soils in Sitka or in
sediments in Silver Bay (Table 6). The measured concentrations (10, 12 and 25
parts per trillion) were similar to the corrected (1/2 detection limit) values
presented in Table 6. The levels of dioxins and furans were primarily due to
the presence of Octachlorodibenzodioxins (Appendix A, Table A-l) and furans.
Since these compounds are relatively non-toxic (0.001 x 2,3,7,8 TCDD), the
toxic equivalent concentrations in the floating residue were similar to that
found in the soils in Sitka.

Fish, shellfish and crabs. Fish and shellfish concentrate dioxins and
furans through ingestion of contaminated microorganisms, sediments or water.
Therefore, they are a good indicator of general contamination in the
environment. Measurements of tissue concentrations are used to estimate risk
to human health from consumption of these aquatic organisms.
The types of seafood (Table 7), such as bottom fish, were selected
because they tend to concentrate chemicals which may be found in the sediments
at the bottom of the bay. They should therefore be worst case examples of
dioxin and furan contamination. These organisms are part of commerical
catches nor are they the types of seafood which may be actually caught during
sport fishing in Sitka.
Mussels, crabs, and a variety of shrimp (mixed), were caught and
selected for analysis. Crab internal organs and the remainder of the crab
body were analyzed separately. In consultation with NOAA personnel familiar
with the effects of sediment contamination on fish as well as fish life
histories (Long 1990), Pacific sanddab. English sole, and Pacific staghorn
sculpin were selected for analysis. Quillback rockfish were analyzed to
investigate the variability in tissue contamination across marine sampling
stations. Eastern brook trout and rainbow trout were collected from
Thimbleberry Lake and Blue Lake. The whole fish (muscle, skin and internal
organs) from each species was analysed.
Trace levels ( 0.1 parts per trillion to 1.3 parts per trillion before
correction -1/2 detection limit- for analytical error) of dioxins and furans
were found in the tissue samples for Sitka. Since, dioxins and furans tend
to concentrate in organs which are high in lipids (fat) such as the liver, the
whole fish samples will be higher than what may be measured if only the meat
(muscle) were sampled. There was little difference in the levels of dioxins
and furans found in all the aquatic organisms sampled during this study. The
levels were also very close to the limits of detection (1 part per trillion).
The range from the detection limit to 3 parts per trillion is similar to the
background levels in the U.S. and the lowest levels measured in urban (Puget
Sound) environments (Table 7).

Exposure Assessment
To assess the effects of chemicals on people, exposure must be
demonstrated. In the case of the Sitka evaluation exposure to dioxins and
furans could occur through ingestion, inhalation and skin absorption of soils
and dust in the community, ingestion, inhalation and skin absorption of the
floating residue in Silver Bay. and ingestion of fish, crabs and shellfish.
For this screening assessment conservative assumptions were used to
estimate risk from exposure to soils and dust in Sitka and floating residues
in Silver Bay. These assumptions were used:
Exposure Duration for soils:
Child - 6 years
Adult •- 24 years
- 100%
SKIN Contact Rate:
Child and Adult - 1 mg/cm2
Amount Absorbed through SKIN:
Child and Adult -
Body weight:
Child - 10 Kg
Adult - 70 Kg
Quantity of SOIL ingested:
Child - 200 mg per day
Adult - 100 mg per day
Absorption from SOIL
Area of SKIN contact:
Child - 3900 cm2
Adult - 5000 cm2 summer
1900 en? winter
Fish and shellfish consumption is based on the amount of fish, crab,
mussels, and shrimp that a recreational harvester might ingest over a lifetime
(75 years). A consumption rate of 54 grams per day (one quarter pound every
other day) was used as a screening level to estimate fish and shellfish
consumption in this report. This is an average value for recreational
harvesters in the U.S. (Pao, et al., 1982). Since consumption rates may
vary depending on individual preferences, risks are also presented for a range
of consumption rates (Figures 7-9). In addition to the amount and frequency
of fish consumed, it is also important to consider what portions of the fish
may be eaten. Most people would only eat fish fillets and they would discard
the internal organs. Another conservative assumption used in this assessment,
is that someone catches all their fish from Silver Bay.
For crabs, consumption data are presented for two types of tissue: the
hepatopancreas commonly referred to as "crab butter" and muscle tissue. For
the hepatopancreas there are survey data from Puget Sound (DSHS 1986) which
suggest that 14% of the individuals who harvest crabs also eat the
hepatopancreas commonly referred to as "crab butter". In this study the crabs
weighed about 1.5 Ibs (1020.58 grams); the muscle represents 30% of the whole
crab (0.45 Ibs or 202 grams); and, the hepatopancreas represents 0.5 % (0.01
Ibs or 5 grams). For this screening assessment risk estimates are based on an
individual consuming one crab (muscle and/or hepatopancreas) per week over a

lifetime. Figures 7-9 illustrate how the risk estimates would change
depending on individual consumption rates.
Risk Estimates
Risk assessment for carcinogens includes an estimate of carcinogenicity
(carcinogenic slope factor) as well as an estimate of human exposure. The
carcinogenic slope factor is generally based on laboratory studies of animals,
although in some cases there are data from human exposures.
The risk of developing cancer is obtained from carcinogenic slope factor
by multiplying the latter by the actual number of- units of human exposure.
For a given exposure, the higher the slope factor, the higher the risk.
Risk - Carcinogenic Slope Factor multiplied times human exposure
Dioxin Carcinogenic Slope Factor - 15600 per mg per kg-body weight per day
Human exposure may be estimated from the following equation:
Human exposure from soil, water or food consumption = tissue or
soil concentration multiplied times the quantity ingested
multiplied times the duration of exposure divided by the body
weight multiplied by average lifetime
Human exposure for skin contact «= soil or floating residue
concentration multiplied times s"kin surface area multiplied times
contact rate multiplied times the duration of exposure divided by
the body weight multiplied by average lifetime

To estimate the potential for other health effects to occur the
following equation is used:
Ratio - Human exposure divided by the one day health advisory or
lifetime health advisory
one day health advisory - 100 pg/kg-body weight/day
lifetime health advisory - 1 pg/kg-body weight/day
Soils. Risk estimates for exposure to soils assumes people ingest soil,
inhale dust and absorb dioxins and furans through skin contact. The
cumulative risks for developing cancer range from one in one million to twenty
in one million (Table 8; Appendix B, Table B-l). There are a number of
uncertainties in deriving this risk estimate for soils. It is assumed that an
individual spends 30 years in direct contact with soils only from the
locations presented in this study. It is also assumed that large amounts of
chemical are absorbed through the skin. More information about the chemicals
as well as individuals in the community would need to be understood in order
to reduce some of the uncertainty.- In addition to the exposure and toxicity
questions, the concentrations found in the soil are also in question. Since
the levels in the soil were very close to the detection limit, the risk at the
detection limit ( 8 in one million to 20 in one million) is equivalent to the
measured values. When exposures are that close to the detection limit, the
accuracy of the risk estimates is not very good.
Exposures to levels of dioxins and furans measured in soils from Sitka
and surrounding areas does not exceed the one day or lifetime health
advisories for children and adults. Therefore it is not expected that the
soils measured in this study present a health threat for non-cancer effects
(Appendix B).
Floating residue. Contact with floating residues may occur through
recreational activities such as swimming, playing on the beach or fishing.
Exposure may be incidental ingestion of the material, inhalation or skin
absorption. Since, these routes of exposure are similar to those for soil,
the same assumptions as were used to derive the risk assessments for soil were
used for the floating residue. The risks range from 2 in 100.000 to 4 in
100,000 (Table 8). It should be noted that .these risks are based on an
assumption that a child is exposed for 6 years every day to this material and
an adult for 24 years, every day. The likelihood of encounters with floating
residue occurring daily over a 30 year period are probably quite low.
Therefore, the risks for individuals who live in or visit Sitka are more
likely to be lower than this estimate.

Fish. Shellfish and Crabs. While risk estimates may be calculated for
the aquatic organisms collected during this study, there is a great deal of
uncertainty in the levels of dioxins and furans which were reported for the
fish tissue. The concentrations of dioxins and furans measured in seafood
were at the limits of the laboratories chemical analytical capability. When
tissue concentrations are close to the detection limit the accuracy of the
risk estimate is questionable. Therefore, the risk estimates are clearly a
maximum worst case estimate and may in fact be zero. Using the screening
consumption of one 1/4 pound of seafood every other day, the data from this
study indicate that the maximum risk of developing cancer could be two in ten
thousand (Table 9; Appendix B). This estimate will vary depending on
individual consumptions rates (Figures 7-9). In estimating risks for
consumption of fish it is also assumed that all seafood which an individual
ingests are caught in Silver Bay. Since, the projected risks for consumption
fish are at levels which may cause some health concerns, it should be
understood that these risks are projected for only the worst case exposures.
The assumptions used to derive these estimates need to be refined in order to
better approximate the actual risk which may result from fish consumption in
Sitka.
Consumption of whole fish, shellfish or crabs collected during this
study does not result in a daily intake which exceeds the one day health
advisory. Upper bound exposures may exceed the lifetime health advisory
(Appendix B).

USEPA Region 10 Laboratory 11/27/90
Below are the definitions for qualifiers used in the GC/MS Organics
area when qualifying Semivolatile, Volatile, PAH, Resin Acids, and
Guaiacol/Catechol/Phenolics analysis results.
Data Qualifiers
U - The analyte was analyzed for, but not
detected, the associated numerical value
is the sample quantitation limit.
J - The analyte was analyzed for, and was
positively identified. However, the
associated numerical value is an estimate
only.
REJ - The data are unusable for all purposes.
The analyte was analyzed for, but the
presence or absence of the analyte has not
been verified.
N - There is presumptive evidence the analyte
is present.
NJ - A combination of "N" and "J" qualifiers.
There is presumptive evidence that the
analyte is present. The asstsc-rated
numerical value is an estimate of the
concentration of the analyte in this
sample.
UJ A combination of "U" and "J" qualifiers.
The analyte was analyzed for, and was not
present above the level of the associated
value. The associated numerical value is
an estimate of the quantitation limit of
the analyte in this sample.
NAR - There is no analysis result for this
analyte.
* - The analyte was present in the sample.

-------
USEPA Region 10 Laboratory 11/28/90
Below are the definitions for qualifiers used in the Metals area
when qualifying data from metals analysis.
Data Qualifiers
U - Element was analyzed for but not detected.
The associated numerical value is the
instrument detection limit/method
detection limit.
j - The analyte was detected above the
instrument detection limit but not
quantified within expected limits of
precision. The laboratory has established
minimum quantitation limits having a
relative standard deviation of no more
than 10%.
E - The reported value is an estimate because
of the presence of interference.
B - Analyte found in the analytical blank as
well as the sample,indicating
possible/probable contamination. "B"
accompanies those analytical results
within 10 (10x) times the instrument
detection limit for the analyte of
interest.
N - Spike sample recovery not within control
limits.
NAR - There is no analysis result for this
analyte.
NA - Not Applicable/Not Required.
* - The analyte was present in the sample.

Scope of Work for TOG and Particle Size Analyses
1. General description of analytical service requested:
Total Organic Carbon (TOC) analysis in sediment by
combustion, using the attached method, dated March 1986.
The samples will also be analyzed for particle size using
method ASTM D422.
2. Definition and number of work units:
There will be 6 low level sediment samples submitted for TOC
and particle size analyses.
3. Estimated date(s) of collection/shipping:
The samples have already been collected.
The samples will be shipped via Federal Express as soon as
laboratory arrangements can be made.
4. Number of days analysis and data required after laboratory
receipt of samples:
The complete data package is required 35 days from receipt of
the samples. The samples will be analyzed for TOC within 7
days of Validated Time of Sample Receipt and are to be stored
at < 4 degrees Celsius.
5. Analytical protocol required:
The attached method, dated March 1986, will be used for the
TOC analyses. Follow Method ASTM D422-63, Particle Size
Analysis of Soils for the particle size analyses.
6. Special technical instructions:
Priority of analyses:
Sample size may be limited for some or all of the samples.
Therefore, TOC shall be analyzed before particle size.
For TOC analyses:
* An infrared C02 analyzer should be used if available,
rather than a gravimetric method.
* Dried samples shall be weighed prior to acidification.
-------
* Report organic carbon results as a percentage of the dry
weight of the unacidified sample to the nearest 0.1 units.
* An initial five point calibration curve that covers the
dynamic range of the detector will be performed at the
beginning of each analytical batch or whenever a calibration
check exceeds specifications. The low calibration standard
shall be at the Quantitation Limit specified in section 9 of
this scope of work. In additiion, the initial calibration
will also include a blank. The percent relative standard
deviation (RSD) of each calibration factor is not to exceed
25% RSD.
* Matrix Spike and Matrix Spike Duplicate analyses are to be
performed on 10% of the field samples utilizing potassium
hydrogen phthalate as the spiking compound. Spiking
concentrations should be approximately half the instrument
calibration range.
* Matrix Spike and Matrix Spike Duplicate results target is
RPD < 35% and the target mean recovery is 75 - 125% .
* Corrective action is required when method blank results
exceed target detection limits.
* Triplicate sample analysis will be performed on sample
90354710. The %RPD for the sample triplicates shall be
reported and shall be < 35%. i
* A calibration check standard will be analyzed after every
ten field or QC samples analyzed. The calibration check
standard will have a concentration equal to the mid-range
standard of the established calibration curve. The response
factor percent differences (%D) between the calibration check
standard and the initial calibration standard will be < 25% .
For particle size analyses:
Analyze one sample in duplicate. Follow method ASTM D422.
Initially weigh each sample aliquot prior to analysis and
determine % recovery relative to the cumulative weights after
fractionating. Note: both sieve and hydrometer analyses are
required.
7. Analytical results required:
The data package for TOC analyses shall include the following:
1. Chain-of-Custody sheets.
-------
2. The bench sheets for sample preparation indicating dates,
times and methods of preparation, standard information, spike
volumes/amounts added,instrument run time/date, etc.
3. All sample and blank results reported as percentage on the
dry weight and all supporting raw data including: run logs,
computer printouts, calibration factors and QC results. All
computer printouts will be labeled with a minimum of the sample
number, and date/time of analysis.
4. All standard data including: preparation logs, traceability
of standards, calibration factors (and RSD where applicable) for
all standards analyzed.
5. All QC data including: summary forms, raw data and
calculations.
6. An example calculation with the formula and all definitions
of parameters in the formula in sufficient detail to allow an
independent third party reconstruction of the results from the
raw data.
The data package for particle size analyses shall include the
following:
1. All Method D422-63 data reporting and documentation
requirements.
i
2. The final results for each sample and it's duplicate.
3. All information used in calculating sample results.
4. Chain-of-Custody sheets.
4. Data on balance calibration checks for each day that samples
are weighed.

At the request of Bruce Duncan, four APC samples were analyzed
for salinity on 9/11/90 by Phil Davis. These sample numbers are
90354700, 4701, 4702, and 4709. The request was for the analysis
to be done on the top, middle, and bottom of the sample, which Phil
did. Unfortunately, there is no simple way to report three values
for each sample number with the data management system we presently
use.
Rather than assign new sample numbers to the middle and bottom
results, for example, we decided it would be best to report the
results in the form of a memo.

APC has been selected for a multimedia compliance inspection which will involve
EPA and ADEC program inspectors (Attachment A) during the week of August 27, 1990.
Previous studies of APC air emissions, wastewater discharges, and fly-ash disposal
practices have raised concerns about dioxin contamination in soil, sediment, air,- water, and
biota in the vicinity of APC. Because of this, additional sampling ( Attachment 'B) will be
conducted during the same week to obtain data for a preliminary human health risk
assessment study. Proposed sampling locations associated with this risk assessment phase
are also listed in general terms in Attachment B.
The primary objectives of the August 27-31, 1990 APC survey are:
Media program compliance inspections
Human health risk assessment. The details of the toxicity and exposure
assessments are shown on Attachment A.

SAMPLE COLLECTION PROCEDURES:
"Waste-water: One 24-Hour composite final effluent sample will be obtained by automatic
sampler. In addition, 12-hour manual composite samples will be taken from
the bleach plant discharges, the treatment plant influent and effluent and the
final effluent..
Other water samples from Silver Bay and Blue Lake will be as shown on
Attachment B and will also include TOC, pH, Conductivity, TSS, and TCL.
Water The marine water composite samples will be made up of approximately
equal aliquots from the surface (5 Ft depth), mid point and bottom locations
at each station using a Kemmerer sampler (Stainless or Teflon) or similar
sampling device. The same sampler will be used at each location following
a thorough ambient water rinse. A Hydrolab will be used for field analytical
measurements.
Leachate Leachate samples will be obtained manually from the APC and city landfills.
Ash: Bottom ash from the APC and KPC hog fuel boilers will be collected using
a stainless steel scoop or other appropriate sampling device as determined
on location.
Sediment: Open water and near shore sediment samples will be collected from 4 areas
in marine waters and from Thimbleberry Lake, Beaver Lake.
Debris or other objects larger than 0.5 inch diameter will be removed before
placing the sample in the container.
Marine sediments will be collected using a stainless steel Van Veen grab
sampler or other appropriate device. The upper 5 cm will be sampled from
the center of each grab using clean stainless steel spoons. Two 8-oz wide
mouth glass jar will be collected at each site for archiving. In addition,
approximately equal portions of sediment from each of the four area
locations will be composited into a half-gallon wide mouth glass jar or
stainless steel pan. Sediments in this jar or pan will be mixed using a
stainless spoon and a portion of this sample will be placed into 3, 8-oz and
1, 120 ml glass jars. Orte of the 8-oz jars will be archived, one will be sent

the the appropriate laboratory for dioxin analysis, and the third will be sent
to Region 10 lab along with the 120 ml jar for TQL analysis. Sample
suitability will be judged according to the Puget Sound Protocols.
Freshwater lake sediment samples will be collected at the shoreline directly
into appropriate containers using stainless steel spoons.
Soil: Surface soils will be sampled using a stainless steel scoop or other
appropriate sampling device. Compositing of discrete samples will be done
in stainless steel bowls. The depth of the sample will not exceed 2 inches
below the ground surface. Objects larger than 0.5 inch diameter will be
removed before placing the sample in the sample jar. If the sampling
location is covered by vegetation, the turf will be separated from the soil and
discarded. The thickness of the discarded turf will not be included in the
2-inch depth determination.
Tissue: Whole organisms - bottomfish, crab, clams, trout - will be obtained by
normal methods and will be frozen aboard the boat, identified and wrapped
in aluminum.foil for shipment to the laboratory.
Following the procedures used in the National Bioaccumulation Study
(1986), whole fish, crab, clams and mussel samples will be wrapped in
aluminum foil and frozen ASAP for shipment to the analytical laboratory.
Tissue compositing will be done at the lab as part of the analytical
procedure. The composite sample should not exceed 20 pounds. The
weight, length, and species will be included on the sample data sheet. For
sport or high utilization fish, the lab will analyze fillets. For bottom feeder
fish, the whole fish will be analyzed.
Air: Certain air streams within APC will be sampled using evacuated canisters
during the air compliance inspection. Sources to be sampled and analyzed
for chloroform will be determined on site during the inspection but are
thought to be from the vent system from the bleaching operation.
Approximately ten in-plant air samples will be obtained.
