Re:
Benzene Exposure Survey
I enclose a copy of the benzene exposure survey which was developed by Roger Daniel of Dow per request at the May 10 Panel meeting. The purpose of the survey is to gather exposure information for response to anticipated OSHA rulemaking on ben zene .
The target,date for return of the questionnaire to CMA is June 10, 1983.* In order to maintain confidentiality, any com pany identification accompanying the returned questionnaire will be removed and the information collated by CMA staff or legal counsel {Wilmer, Cutler and Pickering). Results of the survey will be made known to all Panel members.
