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. G: \WP \1834 \I2246.DOC 5/27/98 1 -1 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 G: \WP \1834 \12246 DOC 5/27/98 1-2 Figure 1 Rayonier Port Ang ;1es Site Air Momtonng Station Location Map G: \WP \1834 \12246.DOC 5/27/98 1 -3 Figure 1, page 2 G: \WP \1834 \12246.DOC 5/27/98 1 -4 1 1 1 1 1 1 1 1 1.3 PLAN MODIFICATIO vS There are no plan modificatio: is to be implemented based on the results of the Apnl 1998 monitonng period.

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.

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. These results are presented on Table 4 Table 4.

Method blanks are laboratory quality control samples that monitor the concentration of contamination that may be in :roduced into field samples as a result of processing in the laboratory These results are presented on Table 5 Table 5.

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 3 -2 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. \\BECALVIN\VOL2 \WP \1834 \12246.DOC 5/27/98 3 -3 4.

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.
