Call from Ram Singh, Amity International

 1/18/06

Ram Singh called to ask about the status of nPB.  I explained that we
have a large amount of new information since our previous proposal
(e.g., Ichihara 2004 studies on workers) and a proposal for a new end
use, coatings.  Based on our current discussions with legal counsel, we
expect to provide this information to the public and take public
comment, probably through a notice of proposed rulemaking.

Ram Singh asked about whether nPB would be acceptable.  I said that this
might vary by the end use, and that adhesive use is of particular
concern.  Mr. Singh inquired about solvent cleaning.  I said that the
information we had seen showed that the vast majority of worker exposure
measurements were able to meet even the ACGIH TLV, making it extremely
likely that we would allow nPB for that sector.  Ram Singh mentioned
that when Amity receives workplace exposure data, no measurements have
been above 5 ppm.

Mr. Singh asked about the status of NTP testing and EPA’s docket.  I
sent him an email with web links to both.
