<p class=MsoPlainText>Hi Barbara,</p>

<p class=MsoPlainText><o:p> </o:p></p>

<p class=MsoPlainText>RAB1 has reviewed the hazard database for novaluron and
determined that<span style='mso-spacerun:yes'>  </span></p>

<p class=MsoPlainText>there is no evidence of immunotoxicity.<span
style='mso-spacerun:yes'>  </span>Therefore, lack of immunotox </p>

<p class=MsoPlainText>studies (as required by the revised part 158) will not
impact the FQPA </p>

<p class=MsoPlainText>factor decision.<span style='mso-spacerun:yes'> 
</span>We recommend the language (provided below) be added to </p>

<p class=MsoPlainText>the FR notice.<span style='mso-spacerun:yes'>  
</span>Please let<span style='mso-spacerun:yes'>  </span>me know if you need
and anything else.</p>

<p class=MsoPlainText><o:p> </o:p></p>

<p class=MsoPlainText>Thanks,</p>

<p class=MsoPlainText><o:p> </o:p></p>

<p class=MsoPlainText>Dana</p>

<p class=MsoPlainText><o:p> </o:p></p>

<p class=MsoPlainText>The toxicology database is essentially complete and there
is no evidence </p>

<p class=MsoPlainText>of immunotoxicity in the hazard database for
novaluron.<span style='mso-spacerun:yes'>  </span>However, the </p>

<p class=MsoPlainText>Revised Part 158 requires immunotoxicity studies be
submitted.<span style='mso-spacerun:yes'>  </span>While the </p>

<p class=MsoPlainText>new Part 158 requirement for an immunotoxicity study<span
style='mso-spacerun:yes'>  </span>have not yet been </p>

<p class=MsoPlainText>fulfilled for novaluron, the existing data are sufficient
for endpoint </p>

<p class=MsoPlainText>selection for exposure/risk assessment scenarios and for
evaluation of the </p>

<p class=MsoPlainText>requirements under the FQPA.<span
style='mso-spacerun:yes'>  </span></p>
