PLAINTIFF'S EXHIBIT -- DIXON INFORMATION INC.---- MICROSCOPY, ASBESTOS ANALYSIS & CONSULTING A.I.H.A. ACCREDITED LABORATORY #10847 NvdAjp CODE 101012 February 9, 1996 ASARCO Technical Services 3422 South 700 West Salt Lake City, UT 84119 . Ref: Batch #33784, Lab #AS1-AS21 Receiver February 1, 1996 Pi eject 3211 L260213-1 through L960213-21 Samples AS1 through AS21 have been analyzed by visual estimation based on EPA-600/M4-32-020 December 1982 optical microscopy test method including phase contrast, polarized .light, dispersion staining, and stereo microscopy. Accuracy increases with increasing asbestos concentration. If these samples are related to a demolition ur are subject to NESHAPS 40CFP. part 61 regulations, these regulations mandate that any sample containing less than 1% asbestos must be analyzed by point count. If asbestos is reported to be between 1% and 10%, see EPA "Clarification of asbestos NESHAP requirements to perform point counting" (copy available). This report relates only to the items tested. This report must not be used to claim product endorsement by the NVLAP, the National Institute of Standards and Technology, or any agency of the U.S. Government. The results of analysis are as follows: Lab AS1. Field L960213-5, CTT-01 Converter Cottrell Hooper This sample contain?, two iy7.es of material: The first type J:~ chrysotile asbestos in black tar; the second type is 5% mineral wool and 20% organic fiber in off-white plaster. This sample is non-homogeneous. The overall asbestos concentration is 16%. The first type is 90% of the sample. The second type is 10% of the sample. Lab AS2, Field L960213-1, CD-03 Baghouse Siding This is 25% chrysotile asbestos in grey cement. Lab AS3, Field L960213-7. LD-01 Mud Insulation This is 5% organic fiber in off-white plaster. detected. Asbestos is none 78 WEST 2400 SOUTH SOUTH SALT LAKE, UTAH 84115-3013 PHONE 801-486-0800 FAX 801-486-0849 RES. 801-583-1840 ASARCO ELP 0015004 Batch #33784 Lab #AS1-AS21 Page 2 Lab AS4. Field L960213-8. LD-03 Brick/Mortar This sample contains two types of material: The first type is tan brick; the second type is off-white sandy plaster. This sample is non-homogeneous. Asbestos is none detected. The first type is 75% of the sample. The second type is 25% of the sample. Lab AS5, Field L960213-9. LD-04 Pipe Insulation This is 4% fiberglass and 6% synthetic fiber in white plaster. Asbestos is none detected. Lab ASS. Field L960213-10. LD-05 Hood Insulation This is 5% organic fiber in off-white plaster. Asbestos is none detected. Lab AS7. Field L960213-11. LD-06 Gasket This is 80% chrysotile asbestos in gray fabric with binder and debris. Lab AS8, Field L960213-12. LD-09 Gasket This is 50% chrysotile asbestos in gray plaster with debris. Lab AS9, Field L960213-14, SNT-01 Expansion Gasket This is 70% heated chrysotile asbestos in brown ' fabric with metallic wire and debris. The fibers in this sample are very brittle and are characteristic of altered chrysotile asbestos. The index of refraction is altered. We suspect this sample has been exposed to high heat. Some of this asbestos may have been converted to forsterite. Lab AS10, Field L960213-13. SNT-02 Gasket This is 80% chrysotile asbestos in gray fabric with binder and debris. Lab ASH. Field L960213-16. SNT-06 Boiler Mud This is 35% mineral wool and 1% plant fiber in gray plaster. Asbestos is none detected. Lab AS12. Field L960213-15. SNT-07 Roofing Tar This is 2% organic fiber in black tar sealant. This sample is nonhomogeneous. Asbestos is none detected. ASARCO ELP 0015005 Batch #33784 Lab #AS1-AS21 Page 3 Lab AS13. Field L960213-17. SNT-08 Back Mortar This sample contains two types of material: The first type is tan brick; the second type is off-white sandy plaster. This sample is non-homogeneous. Asbestos is none detected. The first type is 55% of the sample. The second type is 45% of the sample. Lab AS14. Field L960213-6. RVB-18 3" Pipe insulation This is 20% amosite asbestos and 1% ehrysotile asbestos in white plaster. Lab AS15. Field L960213-18. RVB-19 Back/Mortar This is yellow fire brick. Asbestos is none detected. Lab AS16. Field L960213-19. RVB-20 Floor insulation mud This is 10% ehrysotile asbestos in white plaster. Lab AS17. Field L960213-20. RVB-21 Baghouse seam reinforcement This sample contains two types of material: The first type is 30% ehrysotile asbestos in gray and black binder; the second type is cross-woven fiberglass fabric. This sample is non-homogeneous. The overall asbestos concentration is 18%. The first type is 60% of the sample. The second type is 40% of the sample. Lab AS18. Field L960213-21.
