Emission Test Report EMC WA-2-08 Section 3 Revision: 0 Date: September 30,1999 Page 6 of 33 that Run 1 inlet results are low by a factor of 10 compared to Runs 2 and 3. As is commonly observed, data show a trend for increased dioxinlfuran amounts at the outlet compared with the inlet. There is also a trend for increased dioxinlfuran amounts as SCC temperatures are increased. I I 3.4.5 Results of O2, CO2, S02' NOx, and CO Analysis and Opacity Observations Continuous instrumental analyzers were used for the duration of a cremation to measure scrubber inlet and outlet emissions of O2, CO2, 502, NOx, and CO. A concurrent visible emissions evaluation for opacity was also performed at the chimney outlet. Results of continuous instrumental analyzers monitoring and opacity observations are presented in Table 3-25. The Run 5 cremation in Unit 4 started 30 minutes before the end of a cremation in Unit 1. For the first 30 minutes of Run S, therefore, visible emissions recorded may not reflect the true visible emissions from Unit 4 only. The S02' NOx. and CO instrumental analyzers occasionally recorded gas concentration spikes that exceeded their span. At the end of the test program, the linearity of the analyzers at higher concentrations was demonstrated by using a calibration gas above the highest one-minute average spike measured during the test program. Calibration gas was introduced at the sampling probe, and linearity was demonstrated to meet the accuracy and calibration error requirements of Methods 6C. ?B, and 10 in Appendix A of 40 CFR 60. Data from the post-test linearity checks are contained in Appendix J. 3.4.6 Process Data Process test data and a summary of body/contai~er characteristics are provided in Tables 3-26 and 3-27, respectively. Process data collection forms are found in Appendix B. As denoted in the process data Table 3-26, no ambient odors were noticeable near t~e crematory. However, a slight foul odor could be observed by passersby near the down draft of the stack during the first 2 to 3 minutes. I MRI-AED\R49S 1-08-03 S3.wpd ~.. ; , i
