This letter presents the results of that effort. Table 4 of the blood testing summary prioritizes 12 jobs according to. the concern about possible C-8 exposure. A high priority would be the result ttf a relatively high average C-8 blood level or a blood level that appeared to be increasing. These 12 jobs were reviewed in order of their ranking by C. S. Greenwalt, 3'. I.. Hickman and myself, our procedure was to walk through the job with one or more operators after explaining our purpose to them. After toh& job reviews were completed, 15 operators were interviewed because their C-8 blood levels were much higher or lower than the average for their jobs. A standard questionnaire was used and is attached. Also attached is a summary of the observations and conclusions for each of the 12 jobs. The names of the operators who assisted with the job reviews are listed, but the identities of the interviewed operators are kept confidential. Several general conclusions can be made: o There are many possible reasons for wide variations in operator C-8 blood levels in a single job. These include differences in neatness, PPE usage, overtime practices, and task patterns. w o The BTO has already installed a number of important improvements in equipment and engineering controls which should result in lower average C-8 blood levels for several jobs. o A number of opportunities exist for doing additional air monitoring or wipe testing that may identify previously unsuspected exposure routes. The pathforward for BTO and site occupational health personnel is to continue evaluating the possibilities for reducing C-8 exposure that have been identified by these job reviews.

Part of the last paragraph described owe pathforward as follows* "We are now in the process of 'reviewing the jobs with higher than average C-8 blood levels to see if we can discover any routes of exposure that can be better-controlled. We are also talking to operators with blood levels at the upper or lower end of the range for their job with the hope of learning something that could be helpful to everyone.11 That last sentence about talking to operators is why you've received this letter. Your C-8 blood level is either higher or lower than that of roost other people who work ia the same job. We can think of two possible reasons Cor this: I) Tour work practices are different from those of other operators and this affects your C-8 level, or 2) You do things the same as everyone else does, but your metabolism is somewhat different and so your body eliminates C-8 a little faster or slower. ' k If the first possibility is true, then we may be able to learn from your esEperience and discover some way to reduce everyone's exposure to C-8. With fill that in mind, we would greatly appreciate it if you would take the time to out the attached questionnaire. You don't have to answer all the questions. you need more room, use the back of the questionnaire or use additional Ifsheets of paper. Mail it back to either one of TO in B180T. Your response will be kept confidential.
