EDC WORK PRACTICE GUIDELINES REVIEW, DRAFT II June 8, 1978 Those Attending: A. G. Baker J. M. Otto D. E. Price A. J. Kubicek C. E. Newton Dr. J. C. Calandra ^Dr. Z. G. Bell R. G. Corley J. C. Delgado P. J. Snyder The purpose of this meeting was to review and discuss the second draft of the EDC Work Practice Guideline prepared by Environmental Affairs, Dr. Z. G. Bell. DISCUSSION 1. The question was raised as to why the internal guideline is proposed at 5 ppm when the current standard is 50 ppm. After considerable discussion, the answers appeared to be: a. This is the level recommended by NIOSH, b. EDC is suspected to be carcinogenic. 2. Has the 5 ppm level been reviewed by medical people? Dr. Bell stated that "Corporate medical" has reviewed this guideline. Although Dr. Calandra had apparently not had an opportunity for review, he stated that all these type compounds would have to be treated almost like it was vinyl chloride, and we should strive for the lowest feasible levels in the workplace. 3. Monitoring requirements were discussed at length. It is not possible to accurately assess the amount of additional monitoring required, since this is a function of how many over-standard readings (repeat monitoring requirement) are obtained. Dr. Bell explained that it was not intended that certain jobs with inherent overstandard exposure be monitored over and over. Once it is established that a certain task involves over exposure, a work practice (respirator requirement) should be established and monitoring discontinued. He cautioned that this would not mean that no effort would be required to affect engineering control. 4. Dr. Calandra directed that a copy of the medical surveillance guidelines be given to Dr. iiennington for his review and information. These are the original - Draft I guidelines, which are more detailed than the Draft II version. 5. The need for quarterly progress reports to the Environmental Affairs Department was questioned, and they indicated that annual reports would be acceptable. EDC WORK PRACTICE GUIDELINES REVIEW, DRAFT II June 8, 1978 6. At the conclusion of the discussion, Mr, Baker stated that the Beaumont Plant would submit its comments in writing, to include estimates of the economic and personnel resources required. It was estimated that the OSHA Contest Case and other work priorities would place the response about September. Dr. Bell responded that the guideline would be issued through Mr. Klimas prior to that date. 7. In response to Mr. Baker's question. Dr. Bell stated that this EDC Work Practice Guideline should take precedence over any effort to implement the "Twelve Point Industrial Hygiene Program". 8. It would appear that these guidelines will be promulgated without consideration of any comments from the Beaumont plant, according to Dr. Bell, since this will probably occur next month while all our attention is still directed toward the OSHA case. Dr. Bell did state, however, that he would recommend to Mr. Klimas that there was less urgency in implementing these guidelines at the Beaumont plant. This is because as consumers of EDC, we do not have the same magnitude of problems as the production facilities. RC: pf cc: Those Attending C. R. Reiche R. E.
