Dear Mr. McLane: 
October 24, 1997 
OfFICE OF 
PREVENTION, PESTICIDES 
AND TOXIC SUBSTANCES 
Subject: Amendment to the -letter' sent on Oct..ober 20, 19'97 that 
discussed the Confidential statement o£ Formula and label 
for AMVAC Chemical Co-rporation' s product Parathion 
ElM 6-3 (EPA Reg. No. 5481-437). 
The Agency . has again reviewed :'lQoU~~JlY,R"mi,,ssjqn of the 
ConfidentUiT -s-tatemerit -(CsF)--ofFoTmula- dated April 16, 1997 for 
the Parathion ElM 6-3 (EPA Reg. No. 5.'1.8.2--437) formulation, and the 
following comment.s. apply: 
1) The % by weight should equal 100%. At this time it appears to 
equal 100.74., This is further .. discussed in item (4). 
2) Amend the EPA registration. number from "4787-3" to "4787-17" for 
the ethyl parathion technical in your product. 
3) The CSF should state the % of active ingredient; the % of 
related compounds in both technicals .. 
For example, methyl parathion contains 77% active ingredient; 3% 
related compounds; and 20% inerts. If the. prod1,lctcontains 36% 
methyl parachion Tas stated in the- CSF) ,then 36 x .77 = 27.72% of 
active ingredient. The related compounds would be 36 x .03 = 
1.08%, then the inerts in methyl parathion would be 36 x .20 = 
7.2%. The_toUll-of these, 27.72 + 1.08 .. 7.2 = 36. 
The same should be- specified f= the_ ethyl parathion technical 
which contains 95% active ingredient, 3% related compounds and 2% 
inerts. If-the product Contains 58.37 of parathion technical (as 
stated in the CSF), then 58.37 x .95 = 55.45% of active ingredient. 
The related compounds WOuld be 58.37 x .03 = 1.75%, then the inerts 
in ethyl parathion would be 58.37 x .02 = 1.17%. The total Q£ 
these, 55.45';' 1.75 + 1.17-~58.37.

However, the total .. exceeds 1ITO%. I suggest that you make

Please make the changes noted above .. to, the label 'and CSF, then 
resubmi t them as soon as P9s'sible. Once I' ve received your updated 
CSF and label ti:Ll respond within a few days_ I realize that you 
may have questio:J.s about the above information, T can be reached
