ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 180
[OPP-300416; FRL-5349-7]
RIN 2070-AC18
Pesticide Tolerance for Prosulfuron
AGENCY: Environmental Protection Aqency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA proposes to extend the tolerances for residues of the 
herbicide prosulfuron, 1-(4-methoxy-6-methyl-triazin 2-yl)-3-[2-(3,3,3-
trifluoropropyl)-phenylsulfonyl]-urea in or on the raw agricultural 
commodities corn (forage, fodder, grain and fresh [including sweet 
kernels plus cobs with husks removed]) at 0.01 part per million (ppm), 
milk at 0.01 ppm, and fat, kidney, liver, meat by-products, of cattle, 
goats, hogs, horses, and sheep at at 0.05 ppm. The Agency has not 
completed the regulatory assessment of our science findings; therefore, 
the Agency is proposing to extend these tolerances until December 1999.
DATES: Comments must be sumitted by April 5, 1996.
ADDRESSES: By mail, submit written comments, identified by the docket 
number [OPP-300416] to: Public Response and Program Resources Branch, 
Field Operations Division (7506C) Office of Pesticide Programs, 
Environmental Protection Agency, 401 M St., SW., Washington, DC 20460.

should be submitted through e-mail. Electronic comments on this 
proposed rule may be filed online at many Federal Depository Libraries.

SUPPLEMENTARY INFORMATION: EPA issued a final rule, published in the 
Federal Register of (60 FR 24788, May 10, 1995) which established 
tolerances for residues of the herbicide prosulfuron, 1-(4-methoxy-6-
methyl-triazin-2-yl)-3-[2-(3,3,3-trifluoropropyl)-phenylsulfonyl]-urea 
in or on the raw agricultural commodities corn (forage, fodder, grain, 
and fresh [including sweet kernels plus cobs with husks removed]) at 
0.01 ppm, milk at 0.01 ppm, and meat, fat and meat by-products, of 
cattle, goats, hogs, horses, and sheep at at 0.05 ppm, with an 
expiration date of December 31, 1995 [PP 4F4336/R2133]. These 
tolerances with an expiration date were required by EPA to allow the 
petitioner, Ciba-Geigy Corp. to submit additional data concerning the 
method trial and corn metabolism and ruminant metabolism data. The 
petitioner has submitted the method and the method has been validated 
by an independent laboratory. Additional time is being required to 
complete review of this method trial and allow additional time to 
complete and submit the required metabolism data.
    Based on the information cited above and in the document 
establishing the time-limiting tolerance for prosulfuron (60 FR 24788), 
the Agency has determined that when used in accordance with good 
agricultural practice, this ingredient is useful and the tolerances 
will protect the public health. Therefore, EPA is proposing to 
establish the tolerances as described below.
    Any person who has registered or submitted an application for 
registration of a pesticide, under the Federal Insecticide, Fungicide, 
and Rodenticide Act (FIFRA) as amended, which contains any of the 
active ingredients listed herein, may request within 30 days after 
publication of this document in the Federal Register that this 
rulemaking proposal be referred to an Advisory Committee in accordance 
with section 408(e) of the Federal Food, Drug, and Cosmetic Act.
    Interested persons are invited to submit written comments on the 
proposed regulation. Comments must bear a notation indicating the 
docket number [OPP-300416]. All written comments filed in response to 
this petition will be available in the Public Response and Program 
Resources Branch, at the address given above from 8:00 a.m. to 4:30 
p.m., Monday throuqh Friday, except leqal holidays.
     A record has been established for this rulemaking under docket 
number [OPP-300416] (including comments and data submitted 
electronically as described below). A public version of this record, 
including printed, paper versions of electronic comments, which does 
not include any information claimed as CBI, is available for inspection 
from 8 a.m. to 4:30 p.m., Monday through Friday, excluding legal 
holidays. The public record is located in Room 1132 of the Public 
Response and Program Resources Branch, Field Operations Division 
(7506C), Office of Pesticide Programs, Environmental Protection Agency, 
Crystal Mall #2, 1921 Jefferson Davis Highway, Arlington, VA.
    Electronic comments can be sent directly to EPA at:
                  opp-Docket@epamail.epa.gov
    Electronic comments must be submitted as an ASCII file avoiding the 
use of special characters and any form of encryption.
    The official record for this rulemaking, as well as the public 
version, as described above will be kept in paper form. Accordingly, 
EPA will transfer all comments received electronically into printed, 
paper form as they are received and will place the paper copies in the 
official rulemaking record which will also include all comments 
submitted directly in writing. The official rulemaking record is the 
paper record maintained at the address in "ADDRESSES" at the 
beginning of this document.
    The Office of Management and Budget has exempted this proposed rule 
from the requirements of section 3 of Executive Order 112866.
    Pursuant to the requirements of the Regulatory Flexibility Act 
(Pub. L. 96-354, 94 Stat. 1164, U.S.C. 601-612), the Administrator has 
determined that regulations establishing new tolerances or food 
additive regulations or establishing exemptions from tolerance 
requirements do not have a significant economic impact on a substantial 
number of small entities. A certification statement to this effect was 
published in the Federal Register of May 4, 1981 (46 FR 24950).
