On June 28, 1977, the U.S. Court of Appeals for the District of slouch (joiumhia ruled that the asbestos standard requires medical examinations for jhose in occupations exposed to airborne asbestos "in any measurable X ;oncentration". A letter from Dr. Joyner, along with a legal opinion from IICR CHEU nx rynn Aurelius, suggest a change in our 1972 advice. SURf MAINE S On this basis, we are revising our 1972 guidance to include in the ifiedical surveillance program all employees who are regularly exposed to .isbestos fibers greater than 5 microns long in concentrations above 0.1 f/cc sarTief* res or 8 hour TWA. We believe this is a reasonable level for defining "exposure' ,3 j SURI REFINERY uantitatively at this time. The intent is to include people who work with isbestos-containing products on a regular basis. For example, candidates for exposure monitoring would include the maintenance man who repairs asbestos- :ontaining insulation or the one who cuts it from around valves on a regular SUF'TlRPER >as is. We anticipate that this new protocol will require you to identify su^tmaintn~-hose jobs in which people may be "regularly" exposed, conduct appropriate -nonitoring to determine the exposure level and include in the medical '"hc-rdispatch monitoring program those exposed above 0.1 f/cc TWA. Please provide to t&s heir fciJ"Dr. Joyner a list of employees who are included in the medical monitoring `program. 4>\ It has been shown that people who both smoke and work with asbestos are several times more at risk to develop lung cancer than those who work s-jki mzicon tfith asbestos, but don't smoke. People who Are identified as having asbestos PY! McOM-i Uh exposure should be fully informed about this synergistic effect.

It. . oHELL OIL COMPANY fl[ PlfJC.l JO SEE ATTACHED LIST date from DECEMBER 6, 197 7 CORPORATE MEDICAL DIRECTOR subject MEDICAL SURVEILLANCE UNDER ASBESTOS STANDARD The memo on this subject dated November 13, 1972 from the Manager - Industrial Hygiene and the Corporate Medical Director recommended exposure levels at which medical surveillance should be instituted. Since that time, recommendations for allowable exposures have been lowered. This fact, along with the recent decision in the GAF case (see attached legal opinion), leads me to reappraise the former recommendation. On the basis of the legal opinion, Corporate Medical now believes it would be" appropriate and prudent to include in the medical surveillance programs all employees in the following categories: 1. All employees whose jobs require them to work regularly with asbestos, or asbestos-containing insulation and other products. This would include, but not be limited to, employees recognized or assigned as insulators. 2. All other employees who may use or be in contact with asbestos or asbestos-containing materials where the level of exposure can be established as exceeding 0.1 fibers greater than 5 microns in length per cubic centimeter (TWA). When appropriate air monitoring has established which employees are to be included in the medical surveillance program at each location, I would appreciate receiving a list of the names of employees so identified. I would be happy to discuss this further should you have any questions. Attachment R. E.
