FROM G. D. HICKS Massena Operations 1981 November 01 TO MR. ROBERT FLANAGAN Industrial Hygiene RECkJVFD Wuv 6 1981 PLAINTIFFS EXHIBIT AL-1574 .RE: ASBESTOS USE AT MASSENA OPERATIONS This letter is to advise you of the current use status of asbestos materials at Massena. We have been successful in finding substitute materials in many locations, but we still have a number of areas either in need of more appropriate substitutes or enforcement of use of existing materials. To summarize Massena's status of asbestos use I will follow the outline of Haig Sakoian's letter of 1979 July 30, Potential Exposure vs. Material/Use where applicable to Massena. Brakes/Vehicles Equipment Testing needs to be done for affirmation. Cloth/Insulation, Welding Blankets Substitute materials have been implemented in many situations, but some situations still need attention. Personal Protection/Gloves, Mittens, Pads, Coats and Pants Gloves and mitten substitutes have been implemented in a number of situations, but not acceptable in others as outlined in Haig's letter. Some asbestos lined coats have been replaced. Marinite and Marinite Floats/Molten Metal Casting See attached letter R. R. Avery to J. R. Feeley dated 1981 September 17. Ingot plant use of all asbestos materials to be discontinued by first quarter 1982. ^ackinn/General Pumo Packing Tump packing material being applied as in the past. Suitable replacements should be considered on a case by case basis. Paper/Welding Protection, Electrical Insulation Substitutes have been implemented in a number of sit uations. More work needs to be tended here, Rope/Furnace Insulation Some applications still exist here. More attention to possible substitutes should be tried. Tape; Tubing/Furnace Seals, General Insulation Response same as for rope. ALCOA i SF'4'6; Thermocouple Wire faany attempts have been made with substitute materials, essentially with negative results. Much attention and assistance needed here, I have also attached use lists and letters relating to specific applications and substitute materials tried at various loca tions throughout our operations following Haig Sakoian's format. The lists have primary emphasis on our smelting plant opera* tions , with additions showing efforts made to find substitute materials in carbon bake, ingot plant and wire, rod and bar operations. This information should give you a good comparison of current asbestos uses compared to mid 1979, . $ ikc'&o G. D. HICKS GDH:cmc Attachments cc: J.

Thermocouple wire with asbestos covering has been replaced with a fiberglass cover. Asbestos rope which was used to pack bottom blocks has been replaced with K-2 Fiberseal from Pyrotek. Asbestos mitts have been replaced with Keylar mitts. All molten metal marinite with exception to headers will be replaced with marinite I as molten metal marinite is deleted from stock. Headers for our mold packages are being replaced with R-680 material. Working closely with our supplier, ATC, as they can meet our supply demand we will delete molten metal mar inite headers from stock. The 15"0 6x6 FDC and 6x6 HDC have been completed. A new 18-5/8M0 mold package is currently being evaluated, and by the first quarter 1982, this package should be on-stream. This hew package will eliminate the last two pieces of molten metal marinite in the Ingot Plant. All asbestos-containing material in the Ingot Plant should be replaced with a non-asbestos material by the end of the first quarter 1982. R. R. AVERY RRA/bls cc: B. E. Anderson -59A B. R. Bergeson/T. Morales/T. J. Klemp-201 W. T. Burt -201 W. R. Duso -201 W. P. Moore -201 FROM: K. P. BELLOR TO: G. D. HICKS - 30 1981 SEPTEMBER 01 RE: ASBESTOS REPLACEMENT PROGRAM In response to your letter of 1981 August 14 captioned as above, please find attached the requested survey for the Electrical De partment 95, Massena Smelting. The only application of asbestos utilized by Department 95 is asbestos insulated electrical wire. Asbestos insulated electrical wire is used in several high temperature applications throughout Smelting which are described below: 1. Calrod Heaters - Bldgs. 332, 356 and Potroom Crane Lights G. E. Delta Beston Asbestos Braid Rheostat wire is used on the potroom crane light resistors and the calrod heaters Bldgs. 332, 356. Annually, 1000 feet of this wire is used for maintenance purposes. 2. P-225 Jackmotor and Potwiring Both one conductor and two conductor Rockbestos (asphalt impregnated asbestos) insulated wire is currently used for the bridal and daisy chain wiring, respectively on the P-225 pots. Approximately 3000 feet of this wire is used annually for maintenance purposes. In addition, three conductor Rockbestos cable is used for the jackmotor power cables on each P-225 pot and approximately 200 feet of this cable is used annually for maintenance purposes. 3. P-75 Potwiring One conductor Rockbestos and one conductor Continental AHG-X1000 type ACA wire currently is in use for P-75 potwiring. Annually, 2000 feet of this wire is used for maintenance purposes. The above items summarize the asbestos applications for Electrical Department 95. A cross-the-board replacement program for asbestos wire in Smelting has not been implemented. Such a program would be impractical because of the large quantities of asbestos insulated wire installed on both the P-75 and P-225 pots; however, non-asbestos replacements are being tested and used as maintenance necessitates. For example, high temperature silicon insulated wire is gradually replacing the Rockbestos pot wiring on the P-75 potlines. In addi tion, Pittsburgh Smelting Engineering is going to provide Massena with information on additional non-asbestos replacements which are used at other plant locations. These non-asbestos replacements G. D. HICKS 1981 SEPTEMBER 01 Page Two would have similar applications at Massena and could gradually be installed as maintenance necessitates. This will be investigated. K. P. BELLOR KPB:lmw Xc: R. H. Feild D. E. Jackson J. M. Shaw 8
