1 INTRODUCTION AND SUMMARY
Rayonier is implementing an ambient air quality monitoring program during dismantling
and cleanup activities at the former Rayonier Port Angeles pulp mill site The monitonng
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 momtonng
activities for May 1998
The objectives of the Ambient Air Momtonng Plan are
1 Monitor ambient air quality for potential air pollutants related to onsite
activities;
2 Quantify potential offsite transport of project- related emissions; and
3 Assess the effectiveness 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. Rayonier 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 monrtonng commenced in
October 1997 and is currently ongoing.
The air monitoring network consists of four sampling stations located as shown on
Figure 1 Air momtonng 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 Momtonng Plan to use as an
indicator of the effectiveness of onsite emission control methods used during dismantling
and cleanup activities. In the event that single data point concentrations exceed the action
limit criteria, the contingency plan described in the monitoring plan will be implemented.
The results of the May 1998 air momtonng show that the air emission control methods
used during the dismantling work have been effective. The air samples collected around
11
the perimeter 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 monitonng events,
lead samples were collected at four sampling stations during three monitoring events, and
dioxin/furan monitors were operated at three sampling stations during two momtonng
events. The monitoring activities followed the procedures presented in the Ambient Air
Monitoring Plan. Also, three air samples were collected from inside a constructed sealed
enclosure in the Woodmill Transformer Room during the removal of the concrete slab
These samples were analyzed for the PCB congeners in accordance with EPA Method
8082.
A summary of the monitoring results follows.
TSP measurements for the nine monitoring events during May 1998 ranged from
7 9 to 60.3 1.ig/m the site action level is 150 µg/m
Dioxin/furan measurements for the two monitonng events during May 1998
ranged from 0 0001 to 0 0012 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]);
Lead measurements for the three monitoring events during May 1998 were all
below detection limits, the site action level is 1.5 .Lg/m
No visible emissions of asbestos from dismantling activities were observed dunng
routine inspections;
Polychlorinated biphenyl (PCB) sampling results were all below detection limits,
and
Onsite winds were generally light and primarily from the north northwest through
the west- northwest.
Site activities _during this penod included general dismantling, matenal 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, hog fuel boiler dismantling) or site cleanup excavation
activities occurred during May 1998 Brick lining removal from digesters started on May
20 1998 and continued through the end of the reporting penod. Since the mortar used in

2.1 CONSTRUCTION ACTIVITIES
2 RESULTS AND DISCUSSION
General dismantling, asbestos removal, and digester brick removal activities were
underway during May 1998 These activities are presented along with the TSP
monitonng data (Table 1) and with dioxin/furan monitoring data (Table 2)
Dismantling of asbestos- containing matenals occurred throughout May 1998 at the
Digester Building, and Recovery- Boiler Building.
Brick removal from the digesters started on May 20 1998 and continued through the end
of this reporting period. This work was performed in a sealed enclosure used as
containment on the digester vessel.
Portions of the concrete slab in the Woodmill Transformer Room were removed during
this period. A containment system was set up with the exhaust air being filtered through
HEPA filters. Localized PCB sampling was performed in and around the sealed
containment area to ensure that no PCBs were being released off site. No major structure
dismantling activities (e.g., recovery boiler stack dismantling, hog fuel boiler
dismantling) or site cleanup excavation activities occurred during May 1998
2.2 METEOROLOGICAL CONDITIONS
Onsite winds were generally light to moderate and primarily from the north northwest
through the west- northwest during the May 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 momtonng 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 May 1998 ranged from 7 9
µg/m (Station 1 on May 18) to 60.3 µg/m (Station 3 on May 11) The site action level is

The highest TSP concentrations measured during May 1998 was 60.3 µg /m measured on
May 11 at Station 3 (located southwest of the primary dismantling area) This TSP
concentration is 40 percent of the 150 µg /m site action level The three TSP
measurements from the other monitors on May 11 were 20 1 14.2, and 32 311g /m at
stations 1 2, and 4, respectively Wind conditions on May 11 were moderate and
predominantly from the northwest.
2.4 DIOXIN/FURAN CONCENTRATIONS
The dioxin/furan monitoring results, along with the site activities on the sampling day,
are presented in Table 2 Dioxin/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 Monitoring 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.
The dioxin/furan monitoring frequency was adjusted from weekly to once every two
weeks during this monitonng penod. This adjustment was based on achieving three
consecutive months of weekly monitoring that did not exceed action levels, as described
in the Ambient Air Monitoring Plan.
Dioxin/furan measurements for the two monitonng events during May 1998 ranged from
a value of 0 0001 pg/m (2 stations on May 13 and 3 stations on May 27) to 0 0012 pg/m
(Station 1 on May 13) The site action level is 17 6 pg/m
The highest dioxin/furan concentrations measured during May 1998 was 0 0012 pg/m
measured on May 13 at Station 1 (located southeast of the primary mill dismantling area).
This highest dioxin/furan concentration is approximately seven thousandths of one
percent of the site action level. The dioxin/furan TEQ measurements from the other
monitors on May 13 were 0 0001 pg /m at both Stations 2 and 3 Wind conditions on
May 13 were low to moderate, with the highest winds predominantly from the north
northwest through the west northwest.

2.5 ASBESTOS MONITORING
Visual inspection was conducted at site locations where asbestos containing material
removal occurs, in accordance with the Ambient Air Monrtonng Plan. No visible
emission of asbestos from dismantling activities was observed based on reports from
routine inspections by Rayonier and the dismantling contractor personnel. Asbestos
momtonng is conducted to conform to the site action level of no visible emissions of
asbestos.
2.6 LEAD MONITORING
The lead momtonng results, along with the site activities on the sampling day are
presented in Table 3 Lead momtonng events were conducted concurrent with TSP
momtonng events. Bnck lining removal from digesters was underway during the lead
momtonng events.
Lead measurements for the three momtonng events during May 1998 were all below
detection limits. The site action level is 1.5 p.g/m
2.7 PCB MONITORING
During the removal of the concrete slab in the Woodmill Transformer Room, a sealed
containment area and system was set up in accordance with EPA guidance. The air was
filtered through HEPA filters to prevent any possible PCB contamination from exiting
out of the containment. Air samples were taken in and around the containment area to
monitor for PCBs. Three samples were collected (1 from the middle of the containment
area, 1 from next to the air exhaust system, and 1 from just outside the airlock door) and
analyzed form PCB congeners in accordance with EPA Method 8082. All of these
samphng results were below the detection limits.
2.8 DEVIATIONS FROM THE MONITORING PLAN
The May mQnitonng program followed the procedures presented in the final Ambient Air
Monitonng Plan.
A malfunction of the TSP sampler at sampling location 3 occurred on May 26. The
sampler was repaired and placed back into service the next day

3.2 TRIP BLANKS
3 DATA QUALITY
dioxm/furan sample was collected, and before each TSP sample was collected.
Trip blanks were analyzed along with the regular TSP and doxin/Furan samples. Trip
blanks indicate the level of contamination of the sample media during shipping and
handling.
Nine TSP tnp blanks were analyzed during the May 1998 sampling period. The mass of
the nine trip blanks ranged from not detected to 0 0007 g /sample
Two dioxm/furan trip blanks were analyzed during the May 1998 sampling penod. These
results are presented on Table 4

Three lead tnp blanks were analyzed during the May 1998 sampling period. No lead was
detected in the trip blanks.
3.3 LABORATORY METHOD BLANKS
Two doxin/Furan laboratory method blanks were analyzed along with the field samples.
Method blanks are laboratory quality control samples that monitor the concentration of
contamination -that may be introduced into field samples as a result of processing in the
laboratory These results are presented on Table 5

Three lead method blanks were analyzed during the May 1998 sampling period. No lead
was detected in the method blanks.
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 May the
average surrogate recovery rates were within the acceptable range of 50 to 150 percent,
with the exception of one congener (of the nine tested) in one sample (May 14) and one
congener in one trip blank (May 28) The recoveries for these two congeners were 46 and
45 percent, which are both within the laboratory- determined limits of 40 percent.
Therefore, no action was taken, and the data are considered usable for the air monitoring
evaluations.
3.5 LABORATORY CONTROL SPIKES
One laboratory control spike (LCS) was analyzed along with the field samples. The LCS
is prepared using a `blank" matrix (such as a clean filter) A known quantity of all of the
individual dioxin/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 May
LCS recoveries were within the acceptable range of 50 to 150 percent.
3.6 DATA COMPLETENESS
No samples were lost or broken in shipment and all submitted samples were analyzed.
All data are considered usable.

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 joint frequency of occurrence, in percent, of wind speed
and wind direction categories for a particular location and time period. 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 period 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- minute observations obtained from the on -site meteorological
momtonng station. The on -site meteorological monitoring station was down and being
repaired between May 1 1998 to May 13, 1998 therefore, data from the meteorological
monitoring station at the City of Port Angeles wastewater treatment plant was used dunng
this time The City treatment plant is located immediately adjacent to the mill site,
approximately 200 yd directly east of the TSP1 sampling location (as shown on Figure 1)
