North American Refractories Company's Supplemental Rule 220 Compliance in Bank of Alton v. A. P. Green Refractories, with R&D Reports on Eliminating Asbestos (1989)

Plaintiff's Exhibit NAR-187 combines three items. Pages 1-6 are North American Refractories Company's supplemental compliance with the Rule 220 order in The Bank of Alton, executor of the estate of Richard Jamison, v. A. P. Green Refractories et al., Circuit Court of Madison County, Illinois, No. 87-L-1230, mailed July 7, 1989. It adds two expert witnesses, Gary Bayer and Brian J. Kinman, and ends with a service list. Pages 7-10 are deposition pages 87-90 of a NARCO witness who is not named on these pages. The witness describes a research project called "Elimination of asbestos" and agrees that company records show 1963 as the first use of asbestos in any NARCO product. Pages 11-73 are NARCO's internal "Brief Review of Major Specialty Projects," March 1975 to October 1980, excerpted to project RA-835, "Elimination of asbestos from gun mixes." Thirteen reports appear twice, out of date order (first run pp. 11-42, second run pp. 43-73). The reports say asbestos was used as a gunning aid to reduce rebound. In 1975 wood flour and other fibers were tried in NARMAG OH and CM-18. In September 1976 attapulgite clay was chosen for PD-345 and CM-18, and a survey found NARCOLITE, NARCOGUN CO and AEROGUN to be the other products sold in 1975-76 that contained asbestos. By May 1977 NARCOLITE was being converted to Attagel 50, leaving only NARMAG OH GUN at Womelsdorf. A modified AEROGUN made at Farber was tested in 1980, and the October 1980 report calls the program completed.
