II. Background

    Following the enactment of the Food Quality Protection Act of 1996 
(FQPA), EPA reviewed and assessed under the new FQPA aggregate risk 
standard, the existing tolerances of 31 organophosphates (OPs), 
including tetrachlorvinphos (TCVP). In late December 2002, EPA reported 
the results of its assessment of TCVP tolerances in its Tolerance 
Reassessment Eligibility Decision (TRED) document, (67 FR 77491, 
December 18, 2002) (FRL-7279-2).
    The TCVP TRED concluded that the TCVP livestock residue studies 
were not adequate, and recommended that the Agency require the 
registrant to conduct and submit new magnitude of residue (MOR) studies 
to support permanent TCVP tolerances. The TCVP TRED also recommended 
the Agency revoke 4 existing tolerances in commodities supporting TCVP 
uses that were no longer registered. Finally, the TRED recommended that 
the Agency use existing TCVP metabolism studies to modify 5 existing 
livestock tolerances (fat of cattle, hogs and poultry as well as eggs 
and milk fat) and establish 11 tolerances for additional tissues of 
cattle, hogs and poultry (such as meat, meat byproducts and kidney and 
liver). Specifically, the TRED recommended that EPA establish 16 TCVP 
tolerances as ``time-limited for a period of 18 months * * * to permit 
sufficient time for the registrant to submit the required MOR 
studies.'' TCVP TRED at 41. On February 6, 2004, EPA issued a Generic 
Data Call-In Notice requiring the registrant to conduct and submit new 
livestock MOR studies for meat, milk, poultry, and eggs.
    On February 6, 2008, pursuant to section 408(e) of the FFDCA, EPA 
proposed to revoke, modify and establish tolerances for 10 pesticides, 
including TCVP (73 FR 6867) (FRL-8345-2). EPA explained that the 
proposed tolerance actions were a ``follow-up to the Agency 
reregistration program under Federal Insecticide, Fungicide, and 
Rodenticide Act (FIFRA), and tolerance reassessment program under FFDCA 
section 408(q).'' Id. As such, EPA proposed to implement the tolerance 
recommendations made in the TCVP TRED by:
    (1) Revising the tolerance expression in 40 CFR 180.252 to regulate 
the residues of TCVP and its metabolites;
    (2) Revise and establish 16 time-limited TCVP livestock tolerances 
to reflect levels of TCVP and its metabolites in various metabolism 
studies; and
    (3) Revoke tolerances for residues of TCVP for goat fat and horse 
fat. Specifically, EPA proposed to establish the 16 TCVP tolerances for 
``18 months to permit time for the submission of additional MOR data to 
support permanent tolerances.'' (73 FR 6867, February 6, 2008). Because 
the Agency was taking action to establish tolerances in/on beef cattle, 
hog and poultry commodities, EPA determined that the exception that 
permitted the use of TCVP as an additive to beef cattle, dairy cattle, 
horse and swine feed at certain rates was no longer necessary. On 
September 17, 2008, EPA finalized the rule as proposed, establishing, 
among other things, 16 time-limited tolerances for TCVP with an 
expiration date of March 17, 2010 (73 FR 53732) (FRL-8375-2). For both 
the proposal and the final rule, EPA determined that the ``increased 
tolerances and new tolerances to be established are safe; i.e., there 
is a reasonable certainty that no harm will result from aggregate 
exposure to the pesticide chemical residue.'' (73 FR 53732, September 
17, 2008).
    It was EPA's intention that upon submission of the required TCVP 
MOR studies, the time-limited tolerances would be extended to allow EPA 
sufficient time to review the data with the expectation that the data 
would support the establishment of permanent tolerances. Prior to March 
17, 2010, the registrant did in fact submit MOR data in cattle (MRID 
47193001), MOR data in poultry (MRID 47589301), and the livestock 
validation methodology (MRID 47369201). However, due to a mistake on 
the part of EPA, the data were not reviewed in a timely manner. 
Compounding this error, EPA also failed to extend the time-limited 
tolerances to allow for the Agency to review the data and make a 
determination with respect to converting the time-limited tolerances 
into permanent tolerances.
    Accordingly, in order to remedy the Agency's mistake and to be 
consistent with its original proposal and final rule establishing the 
TCVP time-limited tolerances, EPA is proposing to extend the expired 
time-limited tolerances for another 18 months to allow EPA to review 
the livestock MOR data submitted by the registrant as well as 
subsequent submissions, including storage stability data (MRID 
47589301) to support the previously submitted MOR data in poultry, 
storage stability data (MRID 48378101) to support the previously 
submitted MOR data in cattle, and a waiver request for MOR data in 
swine.
    In the TCVP TRED, EPA ``found that, apart from consideration of the 
potential cumulative risks from all of the OPs, each of the tolerances 
would meet the FFDCA safety standard. EPA has not considered the impact 
of these cumulative risks in the reassessment of these tolerances and 
has determined that these tolerances make, at most, only a negligible 
contribution to the overall risks from OPs. Therefore, these tolerances 
can be maintained regardless of the outcome of the OP cumulative 
assessment and any potential regulatory action taken as a result of 
that assessment. Accordingly, EPA ``believes it is appropriate to 
consider these tolerances reassessed for the purposes of section 408(q) 
of FQPA as of July 23, 2002.'' (67 FR 52985, August 14, 2002) (FRL-
7192-4).
    Among the factors EPA considered in making the decision to reassess 
these tolerances were extensive livestock feeding/metabolism studies as 
well as extensive monitoring data that was in agreement with the 
livestock feeding/metabolisms studies. In sum, there were very few 
detectable residues in the OP monitoring data for animal commodities. 
EPA relied upon extensive monitoring data from the U.S. Department of 
Agriculture's (USDA) Pesticide Data Program (PDP) and U.S. Food and 
Drug Administration's (FDA) Total Diet Study (TDS) covering residues of 
multiple OPs in meats and poultry. The residue monitoring data showed 
infrequent detections, and those residues were detected at low levels. 
Out of approximately 400 meat samples analyzed by the TDS for multiple 
OPs from 1991-1999, only 9 samples detected any OP residues (the 
residues ranged between 0.002 ppm and 0.009 ppm). Out of the 
approximately 500 poultry samples analyzed by PDP for multiple OPs from 
1997-2000, only 1 sample detected an OP residue (0.01 ppm) for a 
pesticide that currently has a tolerance. Id. For milk and eggs, 
extensive monitoring data were available from USDA's PDP and FDA's TDS. 
The residue monitoring data showed no detectable OP residues in milk 
(there was only 1 trace sample detected out of approximately 1,800 
samples analyzed by PDP for multiple OPs from 1996-1998). The residue 
monitoring for eggs also showed no detectable OP residues (only 1 trace 
sample was detected out of approximately 1,300 samples analyzed by TDS 
for multiple OPs from 1992-1998). Id.
    In July of 2006, EPA completed the OP cumulative risk assessment 
(CRA), using the best available monitoring data. The updated USDA PDP 
data indicated that OP residues would not be expected to occur in 
significant amounts in meat

[[Page 33187]]

or milk. The analysis in the OP CRA indicated that animal commodities 
do not significantly contribute to OP dietary exposure and total OP 
dietary risk. This characterization was supported by additional 
information, including the updated TDS data. On July 31, 2006, EPA 
finalized the TCVP reregistration eligibility determination by 
concluding that the pesticide tolerances covered by the IREDs and TREDs 
that were pending the result of the OP CRA--including TCVP tolerances, 
meet the safety standard under section 408(b)(2) of the FFDCA.
    In 2008, EPA confirmed that USDA PDP analyses of livestock 
commodities, including milk, poultry, pork, and beef, through 2005 
showed virtually no detectable residues of TCVP (except for 2 lone milk 
samples detected at levels just above the LOQ (less than one part per 
billion), detected out of approximately 5,200 samples analyzed by PDP 
for multiple OPs from 2001-2005. Furthermore, the USDA Food Safety and 
Inspection Service (FSIS) monitors meat for residues of 
tetrachlorvinphos, and there have been no detections of 
tetrachlorvinphos from 2000-2009.

III. Proposal

    EPA on its own initiative, under section 408(e) of the FFDCA, 21 
U.S.C. 346a(e), is proposing to extend the dates of expiration/
revocation for the time-limited interim tolerances for the combined 
residues of the insecticide tetrachlorvinphos (Z)-2-chloro-1-(2,4,5-
trichlorophenyl) vinyl dimethyl phosphate, including its metabolites, 
1-(2,4,5-trichlorophenyl)-ethanol (free and conjugated forms), 2,4,5-
trichloroacetophenone, and 1-(2,4,5-trichlorophenyl)-ethanediol, in or 
on cattle, fat (of which no more than 0.1 ppm is tetrachlorvinphos per 
se) at 0.2 parts per million (ppm); cattle, kidney (of which no more 
than 0.05 ppm is tetrachlorvinphos per se) at 1.0 ppm; cattle, liver 
(of which no more than 0.05 ppm is tetrachlorvinphos per se) at 0.5 
ppm; cattle, meat (of which no more than 2.0 ppm is tetrachlorvinphos 
per se) at 2.0 ppm; cattle, meat byproducts, except kidney and liver at 
1.0 ppm; egg (of which no more than 0.05 ppm is tetrachlorvinphos per 
se) at 0.2 ppm; hog, fat (of which no more than 0.1 ppm is 
tetrachlorvinphos per se) at 0.2 ppm; hog, kidney (of which no more 
than 0.05 ppm is tetrachlorvinphos per se) at 1.0 ppm; hog, liver (of 
which no more than 0.05 ppm is tetrachlorvinphos per se) at 0.5 ppm; 
hog, meat (of which no more than 2.0 ppm is tetrachlorvinphos per se) 
at 2.0 ppm; hog, meat byproducts, except kidney and liver at 1.0 ppm; 
milk, fat (reflecting negligible residues in whole milk and of which no 
more than 0.05 ppm is tetrachlorvinphos per se) at 0.05 ppm; poultry, 
fat (of which no more than 7.0 ppm is tetrachlorvinphos per se) at 7.0 
ppm; poultry, liver (of which no more than 0.05 ppm is 
tetrachlorvinphos per se) at 2.0 ppm; poultry, meat (of which no more 
than 3.0 ppm is tetrachlorvinphos per se) at 3.0 ppm; and poultry, meat 
byproducts, except liver at 2.0 ppm, for a period of 18 months 
following the date of publication of the final rule in the Federal 
Register, in order to provide the Agency with additional time to 
complete the reviews of the submitted livestock MOR data, storage 
stability data, and the waiver request for the swine MOR data.

IV. Statutory and Executive Order Reviews

    This proposed rule establishes a tolerance under section 408(e) of 
FFDCA. The Office of Management and Budget (OMB) has exempted these 
types of actions from review under Executive Order 12866, entitled 
Regulatory Planning and Review (58 FR 51735, October 4, 1993). Because 
this proposed rule has been exempted from review under Executive Order 
12866 due to its lack of significance, this proposed rule is not 
subject to Executive Order 13211, entitled Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use (66 FR 28355, May 22, 2001). This proposed rule does not contain 
any information collections subject to OMB approval under the Paperwork 
Reduction Act (PRA), 44 U.S.C. 3501 et seq., or impose any enforceable 
duty or contain any unfunded mandate as described under Title II of the 
Unfunded Mandates Reform Act of 1995 (UMRA) (Pub. L. 104-4). Nor does 
it require any special considerations under Executive Order 12898, 
entitled Federal Actions to Address Environmental Justice in Minority 
Populations and Low-Income Populations (59 FR 7629, February 16, 1994), 
or OMB review or any Agency action under Executive Order 13045, 
entitled Protection of Children from Environmental Health Risks and 
Safety Risks (62 FR 19885, April 23, 1997). This action does not 
involve any technical standards that would require Agency consideration 
of voluntary consensus standards pursuant to section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (NTTAA), 
Public Law 104-113, section 12(d) (15 U.S.C. 272 note). Since 
tolerances are being established under section 408(e) of the FFDCA, 
such as the tolerance in this proposed rule, do not require the 
issuance of a proposed rule, the requirements of the Regulatory 
Flexibility Act (RFA) (5 U.S.C. 601 et seq.) do not apply. The Agency 
hereby certifies that this proposed action will not have significant 
negative economic impact on a substantial number of small entities. In 
addition, the Agency has determined that this action will not have a 
substantial direct effect on States, on the relationship between the 
national government and the States, or on the distribution of power and 
responsibilities among the various levels of government, as specified 
in Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 
1999). Executive Order 13132 requires EPA to develop an accountable 
process to ensure ``meaningful and timely input by State and local 
officials in the development of regulatory policies that have 
federalism implications.'' ``Policies that have federalism 
implications'' is defined in the Executive order to include regulations 
that have ``substantial direct effects on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government.'' This proposed rule directly regulates growers, food 
processors, food handlers, and food retailers, not States. This action 
does not alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of section 408(n)(4) of the FFDCA. For these same reasons, the Agency 
has determined that this proposed rule does not have any ``Tribal 
implications'' as described in Executive Order 13175, entitled 
Consultation and Coordination with Indian Tribal Governments (65 FR 
67249, November 9, 2000). Executive Order 3175 requires EPA to develop 
an accountable process to ensure ``meaningful and timely input by 
Tribal officials in the development of regulatory policies that have 
Tribal implications.'' ``Policies that have Tribal implications'' is 
defined in the Executive order to include regulations that have 
``substantial direct effects on one or more Indian Tribes, on the 
relationship between the Federal Government and the Indian Tribes, or 
on the distribution of power and responsibilities between the Federal 
Government and Indian Tribes.'' This proposed rule will not have 
substantial direct effects on Tribal governments, on the relationship 
between the Federal Government and Indian Tribes, or on the 
distribution of power and responsibilities between the Federal 
Government and Indian Tribes, as

[[Page 33188]]

specified in Executive Order 13175. Thus, Executive Order 13175 does 
not apply to this proposed rule.
