Propionic Acid and Salts, and Urea Sulfate; Registration Review 
Proposed Decisions; Notice of Availability

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.


SUMMARY: This notice announces the availability of EPA's proposed 
registration review decisions for the pesticides propionic acid and 
salts, and urea sulfate and opens a public comment period on the 
proposed decisions. Registration review is EPA's periodic review of 
pesticide registrations to ensure that each pesticide continues to 
satisfy the statutory standard for registration, that is, that the 
pesticide can perform its intended function without unreasonable 
adverse effects on human health or the environment. Through this 
program, EPA is ensuring that each pesticide's registration is based on 
current scientific and other knowledge, including its effects on human 
health and the environment.

DATES: Comments must be received on or before October 18, 2010.

ADDRESSES: Submit your comments, identified by the docket 
identification (ID) number for the specific pesticide of

II. Background

A. What Action is the Agency Taking?

    Pursuant to 40 CFR 155.58, this notice announces the availability 
of EPA's proposed registration review decision for the pesticides shown 
in the following table, and opens a 60-day public comment period on the 
proposed decisions. The active ingredient propionic acid is a fungicide 
and bactericide that is used to control fungi and bacteria in stored 
hay and grains, inhibit bacterial growth in drinking water for 
livestock and poultry, control mold and fungi in poultry litter and 
animal feed, and sanitize pre-cleaned food contact surfaces. Propionic 
acid is also used as an inert ingredient in pesticide formulations. 
Propionic acid and its salts, sodium and calcium propionates, are 
approved by the Food and Drug Administration (FDA) in the United States 
as Generally Recognized As Safe (GRAS) for use in food. Propionic acid 
and salts, are exempt from the requirement of a tolerance. Urea sulfate 
is used as a desiccant on

[[Page 51057]]

cotton. No food crop uses remain and all tolerances for urea sulfate 
have been deleted.

Urea Sulfate                     EPA-HQ-OPP-2007-02  Andrea Carone
Case Number 7213...............   02                 (703) 308-0122

    The registration review docket for a pesticide includes earlier 
documents related to the registration review of the case. For example, 
the review opened with the posting of a Summary Document, containing a 
Preliminary Work Plan, for public comment. A Final Work Plan was posted 
to the docket following public comment on the initial documents.
     For propionic acid and salts, an endangered species assessment was 
conducted for all uses of propionic acid; however, the Agency 
determined that a health risk assessment was not needed. In addition, 
no data were required at this time to support registrations containing 
propionic acid and salts. The Agency has considered propionic acid and 
salts in light of the standard for registration and safety factors in 
FIFRA and FFDCA, as amended by FQPA. EPA has found that there are not 
likely to be any unreasonable adverse effects to the U.S. population in 
general, and to infants and children in particular, or to non-target 
organisms or the environment from the use of registered pesticide 
products containing propionic acid and salts when currently required 
label instructions are followed. In addition, the Agency has made a 
``No Effect'' determination for endangered species for propionic acid 
and salts. This proposed registration review decision is described in 
more detail in the Propionic Acid and Salts Proposed Registration 
Review Decision, available in the propionic acid and salts docket.
     For urea sulfate, after the publication of the Urea Sulfate Final 
Work Plan, pursuant to section 6(f)(1) of the Federal Insecticide, 
Fungicide, and Rodenticide Act, as amended, the Agency received a 
request to voluntarily cancel all but one registered label for use on 
cotton and then granted the voluntary cancellation request on October 
14, 2008, for all registered use sites besides cotton of urea sulfate 
in the United States. The Agency described the impact of the 
cancellations on the registration review of urea sulfate in the Revised 
Registration Review Ecological Risk Assessment and Effects 
Determination for Urea Sulfate, which was issued on September 3, 2009. 
In this assessment, the Agency made a ``No Effect'' determination for 
federally listed species and designated critical habitats. This 
proposed registration review decision is described in more detail in 
the Urea Sulfate Proposed Registration Review Decision, available in 
the urea sulfate docket.
     Following public comment, the Agency will issue registration 
review decisions for products containing propionic acid and salts, and 
urea sulfate.
    The registration review program is being conducted under 
congressionally mandated time frames, and EPA recognizes the need both 
to make timely decisions and to involve the public. Section 3(g) of 
FIFRA, as amended, required EPA to establish by regulation procedures 
for reviewing pesticide registrations, originally with a goal of 
reviewing each pesticide's registration every 15 years to ensure that a 
pesticide continues to meet the FIFRA standard for registration. The 
Agency's final rule to implement this program was issued in August 
2006, and became effective in October 2006, and appears at 40 CFR part 
155 subpart C. The Pesticide Registration Improvement Act of 2003 
(PRIA) was amended and extended in September 2007. FIFRA, as amended by 
PRIA in 2007, requires EPA to complete registration review decisions by 
October 1, 2022, for all pesticides registered as of October 1, 2007.
    The registration review final rule at 40 CFR 155.58(a) provides for 
a minimum 60-day public comment period on all proposed registration 
review decisions. This comment period is intended to provide an 
opportunity for public input and a mechanism for initiating any 
necessary amendments to the proposed decision. 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 
docket for propionic acid and salts. Comments received after the close 
of the comment period will be marked ``late.'' EPA is not required to 
consider these late comments.
    The Agency will carefully consider all comments received by the 
closing date and will provide a ``Response to Comments Memorandum'' in 
the docket. The registration review decision will explain the effect 
that any comments had on the decision and provide the Agency's response 
to significant comments.
     Background on the registration review program is provided at: 
http://www.epa.gov/oppsrrd1/registration_review. A link to earlier 
documents related to the registration review of propionic acid and 
salts, and urea sulfate is provided at: http://www.epa.gov/oppsrrd1/registration_review/reg_review_status.htm.

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

    Section 3(g) of FIFRA and 40 CFR part 155, subpart C, provide 
authority for this action.
