Enclosed are the Ambient Air Monitoring Reports for the Rayonier Site Dismantling
Project for the month of April 1998 These results are being provided to you as described
in our Ambient Air Monitoring Plan for the project. We are also making this report
available to the public through the Port Angeles Library and the Peninsula College
Library
The results from the air monitoring show that the air emission control methods used
during the dismantling work have been effective The air samples collected around the
penmeter of the work site were well below the air quality action levels that are used as
indicators of effective emission controls.
We are continuing our air monitoring and emission control programs at the site. As
additional results are available, they will be compiled by our consultant, Foster Wheeler
Environmental Corp., and will be forwarded to you and made available to the public

1 1 PURPOSE AND OBJECTIVES
Rayomer is implementing an ambient air quality monitoring program during dismantling
and cleanup activities at the former Rayomer Port Angeles pulp mill site. The momtonng
program was conducted as set forth in the final Ambient Air Monitoring Plan (Foster
Wheeler Environmental 1998). This report presents the results of the air monitoring
activities for April 1998
The objectives of the Ambient Air Monitoring Plan are
1 Monitor ambient air quality for potential air pollutants related to onsite
activities,
2 Quantify potential o Tsite transport of project related emissions, and
3 Assess the effectivei�ss of onsite emission control methods used during
dismantling and cleanup activities.
The site is a former pulp mill facility located at 700 North Ennis Street, Port Angeles,
WA. Rayomer received approval from the City of Port Angeles in July 1997 to dismantle
its former pulp mill facility Following this approval, Rayomer voluntarily committed to
develop and implement an air 'monitoring program. Air monitoring commenced in
October 1997 and is currently ongoing.
The air momtonng network consists of four sampling stations located as shown on
Figure 1 Air monitoring is conducted for potential air pollutants that may be generated
by site activities. The specific pollutants to be monitored and the sampling methods to be
used are based on the site activities conducted during the monitoring period.
Air quality action levels are established in the Ambient Air Monitoring Plan to use as an
indicator of the effectiveness of onsite emission control methods used during dismantling
and cleanup activities. In the 'vent that single data point concentrations exceed the action
limit crrtena, the contingency plan described in the monitoring plan will be implemented.

1.2 SUMMARY OF RESULTS
The results of the April 1998 air momtonng show that the air emission control methods
used during the dismantling work have been effective. The air samples collected around
the penmeter of the work site were well below the air quality action levels that are used
as indicators of effectiveness of emission controls. Total suspended particulate matter
(TSP) monitors were operated at four sampling stations during nine momtonng events,
and dioxin/furan monitors were operated at three sampling stations during five
momtonng events. Sampling location 4 did not record any data between April 15 and 27
because it was being repaired. One lead monitoring event was performed during this
period to indicate if any lead is being released to the environment during the dismantling
activities. No major lead containing structure dismantling activities were conducted
during this period. The momtonng activities followed the procedures presented in the
Ambient Air Monitoring Plan, with minor deviations as noted in this report.
A summary of the momtonng results follows.
TSP measurements for the nine monitoring events during April 1998 ranged from
5.2 µg /m to 58.2 µg /m the site action level is 150 µg /m
Dioxm/furan measurements for the five monitoring events during April 1998
ranged. from 0 0002 to 0 0131 pg /m the site action level is 17 6 pg /m
(dioxin/furan concentrations are reported as 2,3,7,8- tetrachlorodibenzo p- dioxin
[TCDD] equivalents [TEQs]),
No visible emissions of asbestos from dismantling activities were observed during
routine inspections,
Lead measurements for the momtonng event in April 1998 were all below
detection hmits, the site action level is 1.5 µg /m and
Onsite winds were generally light and pnmarily from the northwest through the
southwest and from the east.
Site activities during this penod included general dismantling, material handling, and
asbestos removal. The Washington State Department of Ecology, U S Environmental
Protection Agency (EPA), and City of Port Angeles conducted several site visits and
inspections during this reporting penod. No major structure dismantling activities (e.g.,
recovery boiler stack dismantling, digester dismantling, hog fuel boiler dismantling) or
site cleanup excavation activities occurred during April 1998

2.1 CONSTRUCTION ACTIVITIES
General dismantling and asbestos removal activities were underway during April 1998
These activities are presented along with the TSP monitoring data (Table 1) and with
dioxin/furan monrtonng data (Table 2)
Dismantling of asbestos -cont lini ng materials occurred throughout April 1998 at the
Digestor Building, 5 and 6 Boilers and Recovery
No major structure dismantling activities (e.g., recovery boiler stack dismantling, digester
dismantling, hog fuel boiler dismantling, major lead containing structure dismantling or
site cleanup excavation activities) occurred dunng April 1998
2.2 METEOROLOGICAL CONDITIONS
Onsite winds were generally light and pnmarily from the northwest through the
southwest and from the east during the April 1998 sampling events. A summary of the
meteorological conditions during each sampling event, in the form of wind rose figures,
is presented in Appendix A. The monthly composite wind rose of the wind conditions
during the monthly sampling events is also presented in Appendix A.
2.3 TOTAL SUSPENDED PARTICULATE CONCENTRATIONS
The TSP monitonng results, along with the site activities on the sampling day, are
presented in Table 1 TSP monitoring events were conducted for approximately 24 hours
starting in the morning on the date noted on Table 1
TSP measurements for the nine monitoring events during April 1998 ranged from 5.2
µg /m (Station 4 on April 6) to 58.2 µg /m (Station 1 on April 29) The site action level is
150 p.g /m
The highest TSP concentrations measured during April 1998 was 58.2 µg /m measured
on April 29 at Station 1 (located southeast of the pnmary dismantling area) This TSP
concentration is 39 percent of the 150 .tg /m site action level. The three TSP
measurements from the other monitors on April 29 were 48 4, 54.3, and 48 4 µg /m at
stations 2, 3, and 4, respective .y Wind conditions on Apnl 29 were light and
predominantly from two direr :ions the south- southeast and the north- northwest.

2.4 DIOXIN/FURAN CONCENTRATIONS
The dioxin/furan momtonng results, along with the site activities on the sampling day,
are presented in Table 2. Dioxm/furan monitoring events were conducted for
approximately 24 hours, starting in the morning on the date noted on Table 2. The
dioxin/furan toxicity equivalents (TEQs) are calculated and reported using the EPA
toxicity equivalence factors (TEFs) for the detected congeners, as described in the
Ambient Air Momtonng Plan The TEQs are calculated using the measured value for
each detected congener If a congener was detected in some samples but not in others, a
value of one -half the detection limit was used for calculating the TEQs for those non
detected congeners.
Dioxin/furan measurements for the five monitoring events during April 1998 ranged from
a value of 0 0002 pg /m (Statii n 1 on Apnl 22) to 0 0131 pg /m (Station 2 on Apnl 29)
The site action level is 17 6 pg/m
The highest dioxin/furan concentrations measured during Apnl 1998 was 0 0131 pg /m
measured on Apnl 29 at Stati n 2 (located north of the pnmary mill dismantling area)
This highest dioxin/furan concentration is approximately seven hundredths of one percent
of the site action level. The dioxm/furan TEQ measurements from the other monitors on
April 29 were 0 0045 and 0 0036 pg/m at Stations 1 and 3, respectively Wind
conditions on April 29 were light, with the wind predominantly from two directions the
south southeast and the north-northwest.
2.5 ASBESTOS MONITORING Visual inspection was conducted at site locations where asbestos containing matenal
removal occurs, in accordance with the Ambient Air Monitoring Plan. No visible
emission of asbestos from dismantling activities was observed based on reports from
routine inspections by Rayomi r and the dismantling contractor personnel. Asbestos
monitoring is conducted to conform to the site action level of no visible emissions of
asbestos.
2.6 LEAD MONITORING
The lead monitoring results, along with the site activities on the sampling day, are
presented in Table 3 Lead m mtong events were conducted concurrent with TSP
monitoring events. Lead measurements for the momtonng event in April 1998 were all
below detection limits. The site action level is 1.5 µg /m

2.7 DEVIATIONS FROM 'HIE MONITORING PLAN
The Apnl momtonng program followed the procedures presented in the final Ambient
Air Monitoring Plan (Foster Wheeler Environmental 1998)
A malfunction of the flow controller on the TSP sampler at Sampling Location 4
occurred on April 15 The controller was sent to the sampler manufacturer for repair, and
was put back into service pnor to the Apnl 29 sampling event.

3.1 FLOW CHECKS
One point flow checks on the air samplers were conducted before and after each
dioxin/furan sample was collected, and before each TSP sample was collected.
Tnp blanks were analyzed along with the regular TSP and dioxin/furan samples. Trip
blanks indicate the level of contamination of the sample media dunng shipping and
handling.
Nine TSP trip blanks were analyzed during the April 1998 sampling period. The mass of
the nine tnp blanks ranged from not detected to 0 0010 g/sample
Five dioxin/furan trip blanks were analyzed during the March 1998 sampling penod.

3.4 SURROGATE RECOVERY
Surrogate compounds are also referred to as internal standards and are added to all field
and laboratory quality assurance samples (method blanks, laboratory control spikes) A
surrogate is a compound that is similar to the compound (or compounds) of interest, but
that is not normally found in environmental samples. Surrogates are added to samples to
monitor the effects of 1) the environmental matrix, 2) the sample preparation process, and
3) the analytical process on the recovery efficiency of sample contaminants. For April,
the surrogate recovery rates were low for some delivery groups. In specific, several
delivery groups on April 9, 16, 23, and 30 exhibited recovery rates less than 50 percent
for several congeners. Note that the project specified limits of 50 percent are more
conservative than the laboratory determined limits of 40 percent (i.e., what the laboratory
considers acceptable recovery) Occasional low recovenes can be expected. Two
delivery groups (SDG 098820 and SDG 098953) exhibited the majonty of low
recoveries. A review of these two groups indicated that there was still approximately a
10 to 1 signal to noise ratio for the positively identified components, indicating that if the
compound was present it would be detected. Therefore, no action was taken, and the data
are considered usable for the air monitonng evaluations. A complete list of the
laboratory data with recovery rates less than 50 percent are shown in Table 1 of
Appendix B
3.5 LABORATORY CONTROL SPIKES
Five laboratory control spikes (LCSs) were analyzed along with the field samples. The
LCS is prepared using a "blank" matnx (such as a clean filter) A known quantity of all
of the individual dioxm/furan isomers is added to the LCS sample The LCS is processed
through the same laboratory preparation and analysis steps as the field samples, and
monitors the accuracy of the laboratory preparation and analysis process. Average April
LCS recovenes were generally in the acceptable range of 50 to 150 percent, or laboratory
BECALVIN\VOL2 \WP\1834 \12246.DOC 5/27/98

specified range (60 to 140 or 40 to 135 percent, depending upon isomer). Two congeners
(2,3,7,8 TCDF and 1,2,3,7,8 PeCDD) of one of the LCS were below this limit (33 percent
and 37 percent, respectively) Since other components were within control limits, no
further action was taken, and the data are considered useable for the air momtonng
evaluations.
3.6 DATA COMPLETENESS
No samples were lost or broken in shipment and all submitted samples were analyzed.
All data are considered usabh for the intended purpose.

APPENDIX A
DAILY SUMMARY OF METEOROLOGICAL DATA
Wind rose figures for each sampling event are presented in this appendix (Figures A -1, A -2,
and A -3) A wind rose depicts the point frequency of occurrence, in percent, of wind speed
and wind direction categones for a particular location and time penod. The radials of the
wind rose indicate the direction from which the wind is blowing. The length of each radial
indicates the frequency of occurrence for that direction, and the width of each radial
indicates the wind speed class. Each wind rose figure includes the penod from when the
first sampling monitor was turned on until the last monitor was turned off. A composite
wind rose of the meteorological data during each sampling event is also presented. The
wind roses are based on 10- inute observations obtained from the on -site meteorological
monitoring station. The on -site meteorological monitonng station was down and being
repaired dunng the week of April pri1 24, 1998 to April 30, 1998, therefore, data from the
meteorological monitoring station at the City of Port Angeles' wastewater treatment plant
was used during this time. The City treatment plant is located immediately adjacent to the
Millsite, approximately 200 Ind directly east of the TSPI sampling location (as shown on
Figure 1)
