We will continue to distinguish betwe the two lists as follows: Exposure Standards are not to be exceeded -&S-&TH Exposure Guidelines provide program guidance. The lists have been expanded to include materials which may be of importance at only 1 plant, laboratory chemicals, refrigerants and which may have implications for your Fertile Female protection programs. Several information sources were used in developing the updated lists. Please let me know if you have questions. Very truly yours, VDD:jl Attachments 2907L Ui V. D.
