Addendum
 
 
 
The following communication, received on 13 July 2007, is being circulated at the request of 
the Delegation of the United States.  
_______________  
  
Chlorpropham, Linuron, Pebulate, Asulam, and Thiophanate-methyl;  Tolerance Actions
 
 
EPA is recodifying plant tolerances for chlo rpropham from 40 CFR 180.181(a) to (a)(1) and 
regulate the plant regulator and herbicide chlorpr opham (isopropyl m chlorocarbanilate (CIPC) in 
plants. Also, EPA is removing the interim milk and livestock tolerances (meat, fat, and meat 
byproducts of cattle, hog, horse, goat, and sheep) fo r chlorpropham, recodifying them as permanent 
tolerances and regulating tolerances for the plan t growth regulator and herbicide chlorpropham 
(isopropyl m-chlorocarbanilate [CIPC]) and its metabolite 4-hydr oxychlorpropham-O-sulfonic acid 
(4-HSA).  
EPA is increasing tolerances for the comb ined residues of chlorpropham and 4-
hydroxychlorpropham-O-sulfonic acid (4-HSA) as follo ws: Milk from 0.05 to 0.30 ppm; cattle, fat; 
hog, fat; horse, fat; goat, fat; and sheep, fat from 0.05 to 0.20 ppm; cattle, meat; hog, meat; horse, 
meat; goat, meat; and sheep, meat from 0.05 to 0. 06 ppm; cattle, meat byproducts, except kidney; hog, 
meat byproducts, except kidney; horse, meat byproducts, except kidney; goat, meat byproducts, except kidney; and sheep, meat byproducts, excep t kidney from 0.05 to 0.06 ppm; and cattle, kidney; 
hog, kidney; horse, kidney; goat, kidney; and sheep, kidney from 0.05 to 0.30 ppm.     
 
EPA is decreasing the tolerance in or on pot ato, postharvest from 50 to 30 ppm and revising 
potato, postharvest to potato.  
EPA is establishing a tolerance for the chlorp ropham residues of concern or on potato, wet 
peel at 40 ppm.  The agency determined that these new tolerances are safe; i.e., there is a reasonable 
certainty that no harm will result from aggregat e exposure to the pesticide chemical residue. 
 
This regulation is effective 11 July 2007.  Ob jections and requests for hearings must be 
received on or before 10 September 2007, and may be identified by docket number EPA-HQ-OPP-
2006-0483.

  This action is subsequent to a notice publishe d in the Federal Register 20 September 2006, in 
which EPA issued a proposed rule to revoke, remove , modify, and establish certain tolerances and/or 
tolerance exemption for residues for the herbicide chlorpropham.
