S-metolachlor; Pesticide Tolerance
 
  This regulation establishes tolerances for combined residues (free and bound) of S-
metolachlor in or on the following commodities:   Brassica, head and stem, subgroup 5A at 0.5 part s per million (ppm); Cattle, fat at 0.04 ppm; 
cattle, kidney at 0.20 ppm; cattle, meat at 0.04 ppm ; cattle, meat byproducts, except kidney at 0.04 
ppm; Corn, field, grain at 0.10 ppm; corn, field, stover at 6.0 ppm; corn, field, forage at 6.0 ppm; corn, sweet, forage at 6.0 ppm; corn,sweet, stover at 6.0 ppm; corn, pop, stover at 6.0 ppm; corn, pop, grain at 6.0 ppm; corn, sweet, kernel plus cob with husk  removed at 0.1 ppm; Cotton, gin byproducts at 4.0 
ppm; cotton, undelinted seed at 0.1 ppm; Egg at 0.04 ppm; 6. Garlic, bulb at 0.1 ppm; Goat, fat 0.04 
ppm; goat, kidney at 0.20 ppm; goat, meat at 0.04 pp m; goat, meat byproducts, except kidney at 0.04 
ppm; Horse, fat 0.04 ppm; horse, kidney at 0.20 ppm; horse, meat at 0.04 ppm; horse, meat byproducts, except kidney at 0.04 ppm; Leafy petioles subgroup 4B at 0.10 ppm; Milk at 0.02 ppm; Onion, dry bulb at 0.1 ppm; onion, green at 2.0 ppm; Pea and bean, dried shelled, except soybean, subgroup 6C at 0.1 ppm; Peanut 0.2 ppm; peanut, hay at 20 ppm; peanut, meal at 0.40 ppm; Poultry, fat at 0.04 ppm; poultry, meat at 0.04 ppm; poultr y, meat byproducts, except liver at 0.04 ppm; 
Safflower, seed at 0.1 ppm; Shallot at 0.1 ppm; Sheep, fat at 0.04 ppm; sheep, kidney at 0.20 ppm; 
sheep, meat at 0.04 ppm; sheep, meat byproducts, except kidney at 0.04 ppm; Sorghum grain, stover at 4.0 ppm; sorghum grain, forage at 1.0 ppm; sorghum grain, grain at 0.3 ppm.   Soybean, seed at 0.2 ppm; soybean, forage at 5.0 ppm; soybean, hay at 8.0 ppm; Vegetable, 
foliage of legume, except soybean, subgroup 7A at 15 ppm; Vegetable, fruiting, group 8 at 0.5 ppm;  
Vegetable, legume, edible podded, subgroup 6A at 0.5 ppm; Vegetable, root, except sugar beet, 
subgroup 1B at 0.3 ppm; Vegetable, tube rous and corm, subgroup 1C at 0.2 ppm. 
  Several of the proposed tolerances were subsequently amended as follows: 
Tolerances for vegetable, fruiting, group 8 (except tabasco pepper) at 0.1 ppm; tomato, paste at 0.3 
ppm; a separate regional tolerance for pepper, tabasco at 0.5 ppm; brassica, head and stem increased from 0.5 to 0.6 ppm; corn, pop, grain decreased from 6.0 to 0.1 and barley straw from 0.1 to 0.5 ppm.   G/SPS/N/USA/957/Add.1

 Furthermore, the proposed tolerance of cattle, goat, horse and sheep meat byproducts, except 
kidney at 0.04 ppm was subsequently amended to establish tolerances for meat byproducts, except 
kidney and liver of cattle, goat, horse and sheep at 0.04 ppm and separate tolerances for liver of cattle, 
goat, horse and sheep at 0.1 ppm. The tolerance for poultry, meat byproducts, except liver at 0.04 ppm was also amended to poultry, meat byproducts at 0.04 ppm. 
 
 Additionally, IR-4 proposed to amend 40 CFR 180.368(a)(2) by removing tolerances 
established for the combined residues (free and bound ) of the herbicide S-metolachlor [S-2-chloro-N-
(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl )acetamide], and its metabolites, determined as 
the derivatives, 2-(2-ethyl-6-methylphenyl)amino-1-propanol and 4-(2-ethyl-6-methylphenyl)-2-
hydroxy-5-methyl-3-morpholinone, each expressed as the parent compound, in or on the following 
RAC's: Carrot, roots at 0.20 ppm; Horseradish at 0.20 ppm; onion, green at 0.20; rhubarb at 0.10 ppm; 
swiss chard at 0.10 ppm; and tomato at 0.1 ppm. Th e Agency concurs with this proposal based on the 
fact that these uses are covered by crop group and/or crop subgroup tole rances promulgated under 
section (a)(3) of this ruling. 
 
 Additionally, EPA is establishing tolerances fo r indirect or inadvertent combined residues 
(free and bound) of the herbicide S-metolachlor [S-2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-
methoxy-1-methylethyl)acetamide] its R-enantio mer, and its metabolites, determined as the 
derivatives, 2-(2-ethyl-6-methylphenyl)amino-1- propanol and 4-(2-ethyl-6-methylphenyl)-2-hydroxy-
5-methyl-3-morpholinone, each expressed as the pare nt compound, S-metolachlor in or on the 
following RAC's: Animal feed, nongrass, group 18 at 1.0 ppm; Barley, grain at 0.1 ppm; barley straw 
at 0.1 ppm; Buckwheat, grain at 0.1 ppm; Oat, forage at 0.5 ppm; oat, grain at 0.1 ppm; oat straw at 0.5 ppm; Peanut, meal at 0.4 ppm; rice, grain at 0.1 ppm; rice, straw at 0.5 ppm; Rye, forage at 0.5 ppm; rye, grain at 0.1 ppm; rye straw at 0.5 ppm; Wheat, forage at 0.5 ppm; wheat grain at 0.1 ppm; wheat straw at 0.5 ppm 
 
 These tolerances for the various grains (bar ley, buckwheat, oats, rice, rye, wheat) and 
nongrass animal feeds are being established to cover residues of S-metolachlor in these crops when 
planted as rotational crops following treatment of a primary crop.   This rule is effective 31 August 2005.  Obj ections and requests for hearings identified by 
docket ID number OPP-2005-0326 must be received  on or before 31 October 2005 by Registration
