II. Background

A. What Action is the Agency Taking?

    EPA has reassessed the uses of monocarbamide dihydrogen sulfate 
(Urea sulfate); also known as Enquik, reassessed one existing exemption 
from the requirement for a tolerance, and on June 27, 2005, reached a 
tolerance reassessment decision for this low risk pesticide. Urea 
sulfate is used primarily as an active ingredient in herbicides and 
desiccants on agricultural crops. The Agency has determined that urea 
sulfate readily degrades to urea and sulfate ions in the environment 
and in the human body. The Agency is now issuing for comment the 
resulting Report on Food Quality Protection Act (FQPA) Tolerance 
Reassessment Progress and Risk Management Decision for monocarbamide 
dihydrogen sulfate (Urea sulfate), known as a TRED, as well as related 
risk assessments and technical support documents.
    EPA developed the monocarbamide dihydrogen sulfate (Urea sulfate) 
also known as Enquik, TRED through a modified, streamlined version of 
its public process for making tolerance reassessment and reregistration 
eligibility decisions. Through these programs, the Agency is ensuring 
that pesticides meet current standards under the Federal Food, Drug, 
and Cosmetic Act (FFDCA) and the Federal Insecticide, Fungicide, and 
Rodenticide Act (FIFRA), as amended by FQPA. EPA must review tolerances 
and tolerance exemptions that were in effect when the FQPA was enacted, 
to ensure that these existing pesticide residue limits for food and 
feed commodities meet the safety standard established by the new law. 
Tolerances are considered reassessed once the safety finding has been 
made or a revocation occurs. EPA has reviewed and made the requisite 
safety finding for the monocarbamide dihydrogen sulfate (Urea sulfate) 
tolerances included in this notice.
    Although the monocarbamide dihydrogen sulfate (Urea sulfate) TRED 
was signed on June 27, 2005, certain components of the document, which 
did not affect the final regulatory decision, were undergoing final 
editing at that time. These components, including the summary of 
labeling changes, appendices, and other relevant information, have been 
added to the monocarbamide dihydrogen sulfate (Urea sulfate) TRED 
document. In addition, subsequent to signature, EPA identified several 
minor errors and ambiguities in the document. Therefore, for the sake 
of accuracy, the Agency also has included the appropriate error 
corrections, amendments, and clarifications. None of these additions or 
changes alter the conclusions documented in the June 27, 2005 
monocarbamide dihydrogen sulfate (Urea sulfate) TRED. All of these 
changes are described in detail in an errata memorandum which is 
included in the public docket for monocarbamide dihydrogen sulfate 
(Urea sulfate).
    EPA is applying the principles of public participation to all 
pesticides undergoing reregistration and tolerance reassessment. The 
Agency's Pesticide Tolerance Reassessment and Reregistration; Public 
Participation Process, published in the Federal Register of May 14, 
2004 (69 FR 26819) (FRL-7357-9) explains that in conducting these 
programs, the Agency is tailoring its public participation process to 
be commensurate with the level of risk, extent of use, complexity of 
issues, and degree of public concern associated with each pesticide. 
EPA can expeditiously reach decisions for pesticides like monocarbamide 
dihydrogen sulfate (Urea sulfate), which pose no risk concerns, affect 
few stakeholders, and require no risk mitigation. Once EPA assesses 
uses and risks for such low risk pesticides, the Agency may go directly 
to a decision and prepare a document summarizing its findings, such as 
the monocarbamide dihydrogen sulfate (Urea sulfate) TRED.

[[Page 4505]]

    The tolerance reassessment program is being conducted under 
Congressionally mandated time frames, and EPA recognizes the need both 
to make timely decisions and to involve the public in finding ways to 
effectively mitigate pesticide risks. Monocarbamide dihydrogen sulfate 
(Urea sulfate), however, poses no risks that require mitigation. The 
Agency therefore is issuing the monocarbamide dihydrogen sulfate (Urea 
sulfate) TRED, its risk assessments, and related support documents 
simultaneously for public comment. The comment period is intended to 
provide an opportunity for public input and a mechanism for initiating 
any necessary amendments to the TRED. All comments should be submitted 
using the methods in ADDRESSES, and must be received by EPA on or 
before the closing date. These comments will become part of the Agency 
Docket for monocarbamide dihydrogen sulfate (Urea sulfate). Comments 
received after the close of the comment period will be marked ``late.'' 
EPA is not required to consider these late comments.
    EPA will carefully consider all comments received by the closing 
date and will provide a Response to Comments Memorandum in the Docket 
and regulations.gov. If any comment significantly affects the document, 
EPA also will publish an amendment to the TRED in the Federal Register. 
In the absence of substantive comments requiring changes, the decisions 
reflected in the TRED will be implemented as presented.

B. What is the Agency's Authority for Taking this Action?

    Section 408(q) of the FFDCA, 21 U.S.C. 346a(q), requires EPA to 
review tolerances and exemptions for pesticide residues in effect as of 
August 2, 1996, to determine whether the tolerance or exemption meets 
the requirements of section 408(b)(2) or (c)(2) of FFDCA. This review 
was to be completed by August 3, 2006.
