Emission Test Report r: EMC WA-2-08 Section 4 Revision: 0 -= Date: September 30.1999 Page 7 of 9 ry� 4.1.9 Visible Emissions Determination All visible emissions readings were performed using EPA Method 9 procedures contained in USEPA 40 CFR 60, Appendix A. Appendix E of this report contains the raw field data for the tests. Evaluations of visible emissions from the crematorium stack were made by an observer who was certified in accordance with Section 3.12.1, Subsection 1.3 of the Ouality Assurance Handbook for Air Pollution Measurements Systems: Volume III OTA- /4.77-027b, August 1977). Appendix E contains the observer's certification. J 600 The observer stood at a distance that provided a clear view of the emissions with the sun oriented in the 140" sector to his back. In addition, the observer made observations from a position at which the line of vision was approximately perpendicular to the plume direction. For more detailed information on the observer position, see Appendix E. Opacity observations were made at the point of greatest opacity in the portion of the plume where condensed water vapor was not present. Opacity was read at 15-WC intervals, and readings were made to the nearest 5% opacity with a minimum of `24 observations being recorded. Readings were taken against a clearly visible background which gave the highest degree of contrast. See Appendix E for more detailed information on the observations. 4.2 Analytical Procedures The analytical methodology and procedures used by MM for this project were standardized methods and EPA approved procedures. The analytical methods used on this f project are described below. The 11W SON pertaining to the methods are cited. W 4.2.1 Analysis for PCDDs and PcDFs The sample components recovered from the Method 23 trains (i.e., XAD-2 resin and filter) were combined and extracted in the laboratory using Soxhlet extraction according to MRI SOP CS 154. The procedure for extraction involved placing the XAD-2 resin and filter samples in the Soxhlet apparatus, spiking with "C12 F tMD1PMF internal s quantitation standards, and extracting with toluene for a minimum of 16 hours. The train rinses were extracted with methylene chloride using a separator-y funnel. a= Following extraction the methylene chloride was concentrated to a volume of 1 to 5 mL NW-AEM4951-0"3 sa.urd a s P
