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. 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 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 momtonng penod. 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 event that single data point concentrations exceed the action limit cntena, the contingency plan described in the momtonng plan will be implemented. G: \WP\1834 \11968.DOC 4/29/98 1 INTRODUCTION AND SUMMARY 1 -1 1.2 SUMMARY OF RESULTS The results of the December 1997 air monitonng 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 dunng ten monitoring events, and dioxin/furan monitors were operated at three sampling stations dunng six monitoring events. The momtonng activities followed the procedures presented in the Ambient Air Monrtonng Plan, with minor deviations as noted in this report. A summary of the momtonng results follows. TSP measurements for the ten monitonng events during December 1997 ranged from 4.5 µg /m to 13 0 gg/m the site action level is 150 µg /m Dioxin/furan measurements for the six monitoring events dunng December 1997 ranged from 0 0002 to 0 0108 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, and Onsite winds were generally light and primarily from the south through the west northwest. Site activities during this period 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 period. No major structure dismantling activities (e.g., recovery boiler stack dismantling, digester dismantling, hog fuel boiler dismantling) or site cleanup excavation activities occurred during December 1997 1.3 PLAN MODIFICATIONS The December 1997 monitonng period marks the third consecutive month of weekly TSP and dioxin/furan momtonng results that have not exceeded site action levels identified in the Ambient Air Monrtonng Plan. Consequently, starting in April 1998, the monitoring frequency for TSP and dioxin/furan will be reduced to once every two weeks during G: \WP\1834 \I 1968.DOC 4/29/98 1 -2 t g FOSTER WHEELER ENVIRONMENTAL CORPORATION Strait of Juan de Fuca KEY A TSP High Volume Air Sampler ID PS -1 High Volume Air Sampler Meteorological Monitoring Station 1 3 Figure 1.

No major structure dismantling activities (e g., recovery boiler stack dismantling, digester dismantling, hog fuel boiler dismantling) or site cleanup excavation activities occurred during December 1997 2.2 METEOROLOGICAL CONDITIONS Onsite winds were generally light and primarily from the south through the west northwest during the December 1997 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 month is also presented in Appendix A. 2.3 TOTAL SUSPENDED PARTICULATE CONCENTRATIONS The TSP monitoring 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 ten monitoring events during December 1997 ranged from 4.5 µg /m (two monitors on December 26) to 13 01.1g /m (one monitor on December 3) The site action level is 150 µg /m The highest TSP concentrations measured during December 1997 was 13 0 µg/m measured on December 3 at Station 3 (located southwest of the primary dismantling area) This highest TSP concentration is 9 percent of the 150 µg /m site action level. The three TSP measurements from the other monitors on December 3 were 11 0, 9.2, and 11 8 gg /m Wind conditions on December 3 were light and variable, with the wind predominantly from the south southwest through the west.

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. Dioxm/furan measurements for the six monitoring events during December 1997 ranged from 0 0002 pg /m (one monitor on December 3) to 0 0108 pg /m (one monitor on December 3) The site action level is 17 6 pg /m The highest dioxin/furan concentrations measured during December 1997 was 0 0108 pg /m measured on December 3 at Station 1 (located southeast of the primary dismantling area) This highest dioxin/furan concentration is less than one -tenth of one percent of the site action level The dioxm/furan TEQ measurements from the other monitors on December 3 were 0 0002 pg /m and 0 0105 pg /m Wind conditions on December 3 were light and variable, with the wind predominantly from the south southwest through the west. 2.5 ASBESTOS MONITORING Visual inspection was conducted at site locations where asbestos containing material 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 Rayonier and dismantling contractor personnel. Asbestos momtonng is conducted to conform to the site action level of no visible emissions of asbestos. 2.6 DEVIATIONS FROM THE MONITORING PLAN The final Ambient Air Monitonng Plan (Foster Wheeler Environmental 1998) was prepared subsequent to the December 1997 monitoring activities. The Draft Ambient Air Work Plan (Rayonier 1997) was prepared in October 1997 to support the initial air G' \WP1183411968.DOC 4/29/98 2 -4 momtonng activities at the site. The December momtonng program followed procedures presented in the final Ambient Air Monitoring Plan, with the following deviations Sampling duration for the dioxin/furan momtonng vaned from approximately 24 hours, 48 hours, or 72 hours (depending on sampling event) The duration of the air sampling was modified in December based upon comments received on the Draft Ambient Air Work Plan (Rayonier 1997) The variations in sampling duration were planned to establish the appropriate duration for subsequent monitoring events. The Station 3 dioxin/furan blower motor was replaced as part of normal maintenance on December 31, and was followed with a 5 point calibration. G: \WP \1834 \l 1968.DOC 4/29/98 2 -5 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. 3.2 TRIP BLANKS 3. DATA QUALITY Tnp blanks were analyzed along with the regular TSP and dioxin/furan samples. Tnp blanks indicate the level of contamination of the sample media dunng shipping and handling. Nine TSP trip blanks were analyzed during the December 1997 sampling period. The mass of the nine TSP trip blanks ranged from -0 0028 to 0 0001 g /sample, with an average of -0 0004 g /sample Small amounts of filter material are expected to be lost during handling. Six dioxin/furan trip blanks were analyzed during the December 1997 sampling period. These results are presented on Table 3 The trip blank from the December 3 1997 dioxin/furan sample set has been rejected. The trip blank sample was shipped the day after field samples were shipped, therefore, it is not representative of a true trip blank. The TEQ mass reported for the December 15 trip blank is a result of octachlorodibenzo p- dioxin (OCDD) contamination. The OCDD isomer was also reported in the three field samples associated with this trip blank. Levels of OCDD in field samples that are less than 5 times the contamination in the trip blank are considered not detected at the reported sample quantitation limit. Table 3.

Following this procedure, the laboratory associated sample sets from December 3 and December 10 sampling events under one method blank. Samples from December 22 and December 26 sampling events were associated with a second method blank. One method blank was prepared with each set of samples collected on December 15 and December 31 This gives a total of four method blanks for samples collected in December Method blank results are presented in Table 4 Table 4. Dioxin/Furan Laboratory Method Blank Analysis Results Sample Date Dioxin/Furan TEQ Mass (pg /sample) December 3 and 10 None detected" December 15 None detected December 22 and 26 None detected December 31 None detected 1/ The method blank from December 3 and 10 samples initially was found to contain 210 picograms per sample (pg/sample) of OCDD Five of the seven samples associated with the contaminated method blank also contained measurable concentrations of OCDD The five samples and the contaminated method blank were reprepared and reanalyzed. The method blank was contaminant free upon reanalysis. The five field still contained measurable levels of OCDD The reported dioxin /furan concentrations for these field samples are considered representative since the reprepared method blank was contaminant -free. 3.4 SURROGATE RECOVERY Surrogate compounds 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 December the average surrogate recovery rates were within the acceptable range of 50 to 150 percent. The average recovery rates for the individual samples are presented in Table 5 G: \WP\1834 \I 1968.DOC 4/29/98 3 -2 Table 5.

The LCS is prepared using a "blank" matrix (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. Multiple sample sets may be associated with a single LCS in the same fashion as method blanks. Table 6 presents the average spike recovery rate for each LCS The average LCS recoveries were within the acceptable range of 50 to 150 percent. Table 6.

Complete data packages were submitted by the laboratory for samples collected on December 3, 10 15, and 31 These data packages were reviewed following data \\BECALVIN\VOL2 \WP \1834 \I 1968.DOC 4/29/98 3 -3 validation guidelines recommended by EPA Region 10 Summary data, only, was submitted by the laboratory for samples collected on December 22 and 26 Summary data packages cannot be validated under EPA Region 10 guidelines. No unusual or out of- control events were noted in the case narrative for this data set. Results for samples collected on December 22 and 26 are accepted as reported. The trip blank associated with samples collected on December 3 was shipped separately from the field samples and is considered invalid. Reported results for this trip blank have been rejected. A low concentration of OCDD was detected in the trip blank associated with samples collected on December 15 Concentrations of OCDD in field samples from this date that are less than five times the trip blank contamination are considered not detected at the reported sample quantitation limit. Other than the rejected trip blank result, all other data for these sample sets are considered valid and usable for the intended purpose BECALVIN\VOL2 \WP\1834 \11968.DOC 4/29/98 3 -4 4.
