Introduction

What Action Is the Agency Taking?
The WTC filed a petition dated January 10, 2005 (WTC Petition) with
EPA which, among other things, requested that EPA cancel all registrations for the pesticide carbaryl and revoke all carbaryl tolerances established under section 408 of the FFDCA, 21 U.S.C. 346a
(Ref. 1). It should be noted that the WTC Petition generally raises a subset of identical issues raised by a petition submitted by the
Natural Resources Defense Council (NRDC), which is also dated January 10, 2005 (Ref. 2). Indeed, most of the WTC Petition is virtually a verbatim recitation of the NRDC petition. The primary difference is that the WTC Petition does not address any of the tolerance-related issues raised in the NRDC petition; there is nothing in the WTC
Petition which supports the request to revoke tolerances. Nonetheless, to the extent that the WTC Petition can be construed to raise tolerance-related issues, this Order relies on EPA's response to the
NRDC petition and denies that portion of the WTC Petition that seeks the revocation of the carbaryl tolerances. This document also announces a notice of availability for EPA's response to WTC's Petition to cancel all uses of carbaryl, which may be found in docket number EPA-HQ-OPP- 2006-0801.
-
What Is the Agency's Authority for Taking This Action?
Under section 408(d)(4) of the FFDCA, EPA is authorized to respond to a section 408(d) petition to revoke tolerances either by issuing a final rule revoking the tolerances, issuing a proposed rule, or issuing an order denying the petition. (21 U.S.C. 346a(d)(4)).
-

Statutory and Regulatory Background
-
FFDCA/FIFRA and Applicable Regulations 1. In general. EPA establishes maximum residue limits, or
``tolerances,'' for pesticide residues in food and feed commodities under section 408 of the FFDCA. (21 U.S.C. 346a). Without such a tolerance or an exemption from the requirement of a tolerance, a food containing a pesticide residue is ``adulterated'' under section 402 of the FFDCA and may not be legally moved in interstate commerce. (21
U.S.C. 331, 342). Monitoring and enforcement of pesticide tolerances are carried out by the U.S. Food and Drug Administration (FDA) and the
U.S. Department of Agriculture (USDA). Section 408 was substantially rewritten by the Food Quality Protection Act of 1996 (FQPA), which added the provisions discussed below establishing a detailed safety standard for pesticides, additional protections for infants and children, and the estrogenic substances screening program. (Public Law 104-170, 110 Stat. 1489 (1996)).
EPA also regulates pesticides under the Federal Insecticide,
Fungicide, and Rodenticide Act (FIFRA), (7 U.S.C. 136 et seq). While the FFDCA authorizes the establishment of legal limits for pesticide residues in food, FIFRA requires the approval of pesticides prior to their sale and distribution, (7 U.S.C. 136a(a)), and establishes a registration regime for regulating the use of pesticides. FIFRA regulates pesticide use in conjunction with its registration scheme by requiring EPA review and approval of pesticide labels and specifying that use of a pesticide inconsistent with its label is a violation of
Federal law. (7 U.S.C. 136j(a)(2)(G)). In the FQPA, Congress integrated action under the two statutes by requiring that the safety standard under the FFDCA be used as a criterion in FIFRA registration actions as to pesticide uses which result in dietary risk from residues in or on food, (7 U.S.C. 136(bb)), and directing that EPA coordinate, to the extent practicable, revocations of tolerances with pesticide cancellations under FIFRA. (21 U.S.C. 346a(l)(1)). 2. Safety standard for pesticide tolerances. A pesticide tolerance may only be promulgated or left in effect by EPA if the tolerance is
``safe.'' (21 U.S.C. 346a(b)(2)(A)(i)). This standard applies both to petitions to establish and petitions to revoke tolerances. ``Safe'' is defined by the statute to mean that ``there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.'' (21 U.S.C. 346a(b)(2)(A)(ii)). Section 408(b)(2)(D) directs EPA, in making a safety determination, to: consider, among other relevant factors-- ...
(v) available information concerning the cumulative effects of such residues and other substances that have a common mechanism of toxicity; and
(vi) available information concerning the aggregate exposure levels of consumers (and major identifiable subgroups of consumers) to the pesticide chemical residue and to other related substances, including dietary exposure under the tolerance and all other tolerances in effect for the pesticide chemical residue, and exposure from other non-occupational sources;
(21 U.S.C. 346a(b)(2)(D)(v), (vi) and (viii)).
EPA must also consider, in evaluating the safety of tolerances,
``safety factors which . . . are generally recognized as appropriate for the use of animal experimentation data.'' (21 U.S.C. 346a(b)(2)(D)(ix).
Risks to infants and children are given special consideration.
Specifically, section 408(b)(2)(C) states that EPA: shall assess the risk of the pesticide chemical based on--
(II) available information concerning the special susceptibility of infants and children to the pesticide chemical residues, including neurological differences between infants and children and adults, and effects of in utero exposure to pesticide chemicals; and
(III) available information concerning the cumulative effects on infants and children of such residues and other substances that have a common mechanism of toxicity....
(21 U.S.C. 346a(b)(2)(C)(i)(II) and (III)).
This provision also creates a presumptive additional safety factor for the protection of infants and children. Specifically, it directs that ``in the case of threshold effects, ... an additional tenfold margin of safety for the pesticide chemical residue and other sources of exposure shall be applied for infants and children to take into account potential pre- and post-natal toxicity and completeness of the data with respect to exposure and toxicity to infants and children.''
(21 U.S.C. 346a(b)(2)(C)). EPA is permitted to ``use a different margin of safety for the pesticide chemical residue only if, on the basis of reliable data, such margin will be safe for infants and children.''
(Id.). The additional safety margin for infants and children is referred to
Page 38419
throughout this Order as the ``FQPA Safety Factor.'' 3. Procedures for establishing, amending, or revoking tolerances.
Tolerances are established, amended, or revoked by rulemaking under the unique procedural framework set forth in the FFDCA. Generally, a tolerance rulemaking is initiated by the party seeking to establish, amend, or revoke a tolerance by means of filing a petition with EPA.
(See 21 U.S.C. 346a(d)(1)). EPA publishes in the Federal Register a notice of the petition filing and requests public comment. (21 U.S.C. 346a(d)(3)). After reviewing the petition, and any comments received on it, EPA may issue a final rule establishing, amending, or revoking the tolerance, issue a proposed rule to do the same, or deny the petition.
(21 U.S.C. 346a(d)(4)).
Once EPA takes final action on the petition by establishing, amending, or revoking the tolerance or denying the petition, any party may file objections with EPA and seek an evidentiary hearing on those objections. (21 U.S.C. 346a(g)(2)). Objections and hearing requests must be filed within 60 days. (Id.). The statute provides that EPA shall ``hold a public evidentiary hearing if and to the extent the
Administrator determines that such a public hearing is necessary to receive factual evidence relevant to material issues of fact raised by the objections.'' (21 U.S.C. 346a(g)(2)(B)). EPA regulations make clear that hearings will only be granted where it is shown that there is ``a genuine and substantial issue of fact,'' the requestor has identified evidence ``which, if established, resolve one or more of such issues in favor of the requestor,'' and the issue is ``determinative'' with regard to the relief requested. (40 CFR 178.32(b)). EPA's final order on the objections is subject to judicial review. (21 U.S.C. 346a(h)(1)). 4. Tolerance reassessment and FIFRA reregistration. The FQPA required that EPA reassess the safety of all pesticide tolerances existing at the time of its enactment. (21 U.S.C. 346a(q)). EPA was given 10 years to reassess the approximately 10,000 tolerances in existence in 1996. In this reassessment, EPA was required to review existing pesticide tolerances under the new ``reasonable certainty that no harm will result'' standard set forth in section 408(b)(2)(A)(i).
(21 U.S.C. 346a(b)(2)(A)(i)). This reassessment was substantially completed by the August 3, 2006 deadline. Tolerance reassessment was generally handled in conjunction with a similar program involving reregistration of pesticides under FIFRA. (7 U.S.C. 136a-1). Tolerance reassessment and reregistration decisions were generally combined in a
Reregistration Eligibility Decision (``RED'') document.

EPA's Approach to Dietary Risk Assessment and Science Policy
Considerations
EPA performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. In addition, EPA applies a number of policy considerations with respect to determining the appropriate children's safety factor, cholinesterase inhibition as a regulatory endpoint, and the use of a bench mark dose approach. EPA has discussed these in great detail in its response to an earlier and virtually identical petition file by NRDC. EPA hereby incorporates and relies upon that discussion. See Carbaryl: Order Denying NRDC's
Petition to Revoke Tolerances, dated September 30, 2008 (October 29, 2008, 73 FR 64229).

Carbaryl Tolerances
-
Regulatory Background
Carbaryl is a carbamate insecticide and molluscide that was first registered in 1959 for use on cotton. Carbaryl has many trade names, but is most commonly known as Sevin[reg]. In 1980, the Agency published a position document summarizing its conclusions from a Special Review of carbaryl, and concluded that risk concerns, particularly those related to teratogenicity, did not warrant cancellation of the registration for carbaryl. A Registration Standard, issued for carbaryl in 1984 and revised in 1988, described the terms and conditions for continued registration of carbaryl. At the time carbaryl was assessed for purposes of reregistration, carbaryl was registered for use on over 400 agricultural and non-agricultural use sites, and there were more than 140 tolerances for carbaryl in the Code of Federal Regulations (40
CFR 180.169). For example, carbaryl was registered for domestic outdoor uses on lawns and gardens, and indoors in kennels and on pet sleeping quarters. It was also registered for direct application to cats and dogs (collar, powder, and dip) to control fleas and ticks.
EPA completed an Interim Reregistration Eligibility Decision (IRED) for carbaryl on June 30, 2003 (2003 IRED, Ref. 3). The Agency amended the IRED on October 22, 2004 (2004 Amended IRED. Ref. 4), and published a formal Notice of Availability for the document which provided for a 60-day public comment period (69 FR 62663; docket EPA-HQ-OPP-2003- 0376). EPA received numerous comments on the carbaryl IRED, including two nearly identical petitions from the WTC and the NRDC requesting that EPA cancel all carbaryl registrations and revoke all tolerances
(Refs. 1 and 2). The Agency published a Notice of Availability for the
WTC Petition in the Federal Register, which provided a public comment period. See ``Petition to Revoke or Modify Tolerances Established for
Carbaryl; Notice of Availability,'' October 13, 2006 (71 FR 60511).
The 2004 Amended IRED for carbaryl specified mitigation of risks from residential uses including the following: Canceling liquid broadcast applications to home lawns pending EPA review of pharmacokinetic data to refine post-application risk estimates; home garden/ornamental dust products must be packaged in ready-to-use shaker can containers, with no more than 0.05 lbs. active ingredient per container; cancellation of the following uses and application methods: all pet uses (dusts and liquids) except collars, aerosol products for various uses, belly grinder applications of granular and bait products for lawns, hand applications of granular and bait products for ornamentals and gardens.
On March 9, 2005, EPA issued a cancellation order for the liquid broadcast use of carbaryl on residential turf to address post- application risk to toddlers (Ref. 5). In March 2005, EPA also issued generic and product-specific data call-ins (DCIs) for carbaryl. The carbaryl generic DCI required several confirmatory studies of the active ingredient carbaryl, including additional toxicology, worker exposure monitoring, data to support the use of carbaryl in pet collars, and environmental fate data. The product-specific DCI required acute toxicity and product chemistry data for all pesticide products containing carbaryl; these data are being used for product labeling.
EPA has received numerous studies in response to these DCIs, and, where appropriate, these studies were considered in the tolerance reassessment.
In response to the DCIs, many carbaryl registrants chose to voluntarily cancel their carbaryl products, rather than revise their labels or conduct studies to support these products. EPA published a notice of receipt of these requests in the Federal Register on October 28, 2005 (70 FR 62112), followed by a cancellation order issued on July 3, 2006. One technical registrant, Burlington Scientific, chose to cancel its technical product, leaving Bayer CropScience (Bayer) as the sole
Page 38420
technical registrant for carbaryl. Approximately two-thirds of all of the carbaryl products registered at the time of the 2003 IRED were canceled through this process.
In addition, Bayer, the sole remaining technical registrant responsible for developing data, requested waivers of required exposure monitoring or residue studies because the following use scenarios were not on any Bayer technical or product labels or were to be deleted from
Bayer labels: Carbaryl use in or on pea and bean, succulent shelled
(subgroup 6B); millet; wheat; pre-plant root dip for sweet potato; pre- plant root dip/drench for nursery stocks, vegetable transplants, bedding plants, and foliage plants; use of granular formulations on leafy vegetables (except Brassica); ultra low volume (ULV) application for adult mosquito control; and dust applications in agriculture.
Bayer subsequently requested that all of its carbaryl registrations bearing any of the uses just mentioned be amended to delete these uses.
EPA notified all affected registrants that these uses and application methods must be deleted from their carbaryl product labels. EPA identified 34 product labels from 14 registrants (other than Bayer) bearing these end uses. All of these registrants requested that their affected carbaryl product registrations be amended to delete these uses. EPA published Notices of receipt of these requests from Bayer and the other 14 registrants in the Federal Register on August 20, 2008 and
October 15, 2008. On March 18, 2009, the Agency published an order granting the requests to delete uses (74 FR 11553).
Further, in November 2009, Bayer submitted a waiver request for the dermal and inhalation exposure studies required for aerial application of carbaryl bait used in the USDA Rangeland Grasshopper and Mormon
Cricket Suppression Program due to a recent reduction in the maximum application rate, which eliminated remaining uncertainties associated with this use scenario. The Agency accepted the waiver request in
January 2010.
Carbaryl is a member of the N-methyl carbamate (NMC) class of pesticides, which share a common mechanism of toxicity by affecting the nervous system via cholinesterase inhibition. Specifically, carbaryl is a reversible inhibitor of Acetylcholinesterase (AChE). A cumulative risk assessment, which evaluates exposures based on a common mechanism of toxicity, was conducted to evaluate risk from food, drinking water, residential use, and other non-occupational exposures resulting from registered uses of NMC pesticides, including carbaryl.
In June 2006, EPA determined that the uses associated with 120 of the existing carbaryl tolerances were not significant contributors to the overall NMC cumulative risk and, as a result, these tolerances would have no effect on the retention or revocation of other NMC tolerances. Therefore, EPA considered these 120 tolerances for carbaryl as reassessed on June 29, 2006, and posted this decision on the
Agency's internet site. (See http://www.epa.gov/pesticides/cumulative/ carbamates_commodity.pdf).
In late November 2006, EPA received data from a carbaryl comparative cholinesterase study conducted to determine the comparative sensitivity of adults and offspring to cholinesterase inhibition by carbaryl. These data were used to revise the FQPA Safety Factor for carbaryl for the NMC cumulative risk assessment and to select new toxicology endpoints or points of departure (PODs) for the risk assessment. The Agency determined that it was appropriate to use the new FQPA Safety Factor and revised PODs in both the NMC cumulative risk assessment and the carbaryl-specific human health risk assessment.
Because this necessitated a revision of the carbaryl human health aggregate risk assessment, EPA also considered additional new data generated in response to the DCI, new methodologies, and other new information in performing its most recent assessment of carbaryl and in responding to this Petition. EPA has thus, in effect, revised the carbaryl single chemical assessment in response to the issues raised during the public comment process as well as based upon more recent data and analytical methods.
On September 26, 2007, EPA issued the NMC cumulative risk assessment (Ref. 6). EPA concluded that the cumulative risks associated with the NMC pesticides meet the safety standard set forth in section 408(b)(2) of the FFDCA, provided that the mitigation specified in the
NMC cumulative risk assessment is implemented. EPA has therefore terminated the tolerance reassessment process under 408(q) of the
FFDCA. (See 72 FR 54656). In conjunction with the NMC cumulative risk assessment, EPA completed a Reregistration Eligibility Decision (RED) for carbaryl on September 24, 2007 (Ref. 7) and issued this RED on
October 17, 2007 with a formal Notice of Availability in the Federal
Register (72 FR 58844). In addition to relying on the NMC cumulative risk assessment to determine that the cumulative effects from exposure to all NMC residues, including carbaryl, was safe, the carbaryl RED relied upon the revised assessments and the mitigation that had already been implemented (e.g., cancellation of pet uses except for collars).
In addition, the RED included additional mitigation with respect to granular turf products for residential use; namely, that product labels direct users to water the product immediately after application.
Subsequently, on August 25, 2008, EPA completed an addendum to the
Carbaryl RED, incorporating the results of a revised occupational risk assessment and modified mitigation measures for the protection of workers (Ref. 8).
Subsequent to the completion of the carbaryl RED addendum, EPA completed a revised master label table for carbaryl and a list of carbaryl uses eligible for reregistration. These materials, which summarized the changes necessary to implement the carbaryl RED and addendum, were sent to all carbaryl end-use registrants on March 25, 2009. (See docket entry: EPA-HQ-OPP-2007-0941-0088.) All carbaryl end- use registrants were required to submit revised labels to EPA by April 30, 2009. EPA has completed its review of these amended labels, and all acceptable carbaryl products are now reregistered. Once again, some registrants chose to cancel their carbaryl product registrations rather than submit revised labels that incorporate the final RED mitigation.
EPA has received voluntary cancellation requests for 19 additional carbaryl product registrations, and 7 Special Local Need registrations, from 8 registrants, including the last remaining carbaryl products registered for use on pets - carbaryl-treated dog and cat collars. The
Agency has published Notice of Receipt of Requests for Cancellation and/or Cancellation Notice for all 26 carbaryl product registrations as per sec. 6(f) of FIFRA. The two carbaryl pet collar product registrations, specifically, will be canceled effective September 30, 2010, with a reduced existing stock provision of 3 months (74 FR 66642).
Finally, EPA completed a response to NRDC's January 10, 2005 petition to cancel all uses of carbaryl in a letter dated September 30, 2008 (Ref. 9). The Agency's response to NRDC's petition to revoke carbaryl tolerances is in an Order also dated September 30, 2008 (Ref. 10). This Order Denying NRDC's Petition to Revoke Tolerances was published in the Federal Register on October 29, 2008 (73 FR 64229).

FFDCA Tolerance Reassessment and FIFRA Pesticide Reregistration
As required by the Food Quality Protection Act of 1996, EPA reassessed the safety of the carbaryl tolerances under the safety standard established in the FQPA. In the September 2007 RED for carbaryl, EPA evaluated the human health risks associated with all currently registered uses of carbaryl and determined that there is a reasonable certainty that no harm will result from aggregate, non- occupational exposure to the pesticide chemical residue. In making this determination, EPA considered dietary exposure from food and drinking water and all other non-occupational sources of pesticide exposure for which there is reliable information. (Ref. 7). The Agency has concluded that with the adoption of the risk mitigation measures identified in the NMC cumulative risk assessment, all of the tolerances for carbaryl meet the safety standard as set forth in section 408(b)(2)(D) of the
FFDCA. Therefore, the tolerances established for residues of carbaryl in or on raw agricultural commodities were considered reassessed as safe under section 408(q) of FFDCA, as amended by FQPA, in September 2007. These findings satisfied EPA's obligation to review the carbaryl tolerances under the FQPA safety standard.
To implement the carbaryl tolerance reassessment, EPA commenced with rulemaking in 2008. The Agency published a Notice of proposed tolerance actions in the May 21, 2008 Federal Register (73 FR 29456).
This proposed rule provided for a 60-day public comment period. No comments relevant to carbaryl tolerances were received and EPA published a Notice of final tolerance actions in the September 10, 2008
Federal Register (73 FR 52607). This carbaryl tolerance rule is codified in 40 CFR 180.169.

The Petition to Revoke Tolerances
WTC filed a petition on January 10, 2005, requesting, among other things, that EPA cancel all carbaryl registrations and revoke all carbaryl tolerances. This January 10, 2005 submission is in the form of comments on and requests for changes to the Carbaryl IRED published in the Federal Register on October 27, 2004. (70 FR 62663) (Ref. 1).
Nevertheless, in the introduction to the comments, WTC included a statement that it is also petitioning the Agency to revoke all carbaryl tolerances. It should be noted that the WTC petition primarily raises a subset of identical issues raised by a petition submitted by NRDC, which is also dated January 10, 2005. Indeed, to the extent they address the same issues, most of the WTC's petition is virtually a word-for-word copy of the NRDC petition. The primary difference is that the WTC petition does not address any of the tolerance-related issues raised in the NRDC petition. Nonetheless, to the extent that anything in the WTC Petition could be construed as raising a tolerance-related issue, EPA is relying on its response to the NRDC petition to revoke all carbaryl tolerances in denying the WTC Petition to revoke all carbaryl tolerances.
The issues raised by the WTC Petition center around the ecological risk assessment that supported the 2004 IRED decision. Again, most of these issues are identical to those raised by NRDC and have been addressed in a response denying the NRDC petition to cancel all carbaryl registrations, dated September 30, 2008. The ecological risk assessment issues that are unique to the WTC Petition are addressed in a separate response, dated June 18, 2010. EPA hereby announces the availability of this response in the public docket EPA-HQ-OPP-2006- 0801.
-
Public Comment
In response to the statement that the WTC Petition sought the revocation of the carbaryl tolerances, EPA published notice of the WTC
Petition for comment on October 13, 2006 (71 FR 60511). EPA received 28 comments in response to the notice of availability for the WTC
Petition. These comments may be found in their entirety in docket EPA-
HQ-OPP-2006-0801. A number of commenters from land grant universities mentioned the importance of carbaryl in agriculture, especially in the production of grapes, small fruit, and pecans. Several commenters from the U.S. Forest Service and state departments of forestry commented on the importance of carbaryl in controlling bark beetle. In addition, the carbaryl registrant, Bayer CropScience, submitted comments opposing the claim by the WTC that carbaryl poses unreasonable risks to non-target organisms. In general, these comments focus on the importance and benefits of carbaryl, and are not specific to carbaryl tolerances and, therefore, are not relevant to the requested revocation of pesticide tolerances. EPA is responding to the WTC Petition insofar as it seeks cancellation of all carbaryl products separately, and, therefore, these comments are not directly relevant here.
In addition, one comment from a private citizen supported WTC's petition, asserting that all carbaryl tolerances should be revoked (but without, however, providing sufficient details to substantiate this position). Another commenter, Northwest Horticultural Council, submitted comments stating that WTC's claims are often based on outdated information, such as carbaryl residue levels on apples and pears reported in a 1967 monograph of the Food and Agricultural
Organization (FAO) of the United Nations World Health Organization. The
Northwest Horticultural Council states that the FAO Monograph is superseded by 2004 residue monitoring data from USDA's Pesticide Data
Program (PDP), which shows less than 10% of samples with detection, where carbaryl residues ranged from 0.0005 to 0.49 ppm. In any event, the comments as a whole (including these particular comments) did not add any new information pertaining to whether the tolerances were in compliance with the FFDCA.

Ruling on Petition
This Order responds to the WTC Petition to revoke carbaryl tolerances. As noted above, this request was included as part of WTC's comments on the carbaryl IRED. The WTC Petition contains a number of comments that do not provide a basis upon which to either cancel all carbaryl registrations or revoke all carbaryl tolerances. Moreover, the
WTC Petition focuses solely on ecological issues. EPA is responding to
WTC's comments regarding the ecological assessment supporting the carbaryl RED in a separate response, which is available in docket EPA-
HQ-2006-0801. However, EPA has not attempted to respond to every comment or suggestion for improvement made in the comments provided by the WTC.
EPA hereby denies the WTC Petition to revoke all carbaryl tolerances. The WTC Petition has not demonstrated that carbaryl tolerances are unsafe. Again, the WTC Petition primarily raises a subset of identical issues that were raised in the NRDC petition, and does not provide any factual support for the proposition that the carbaryl tolerances do not meet the FFDCA safety standard. To the extent that the WTC Petition can be construed as raising any tolerance- related issues, in denying the WTC Petition, EPA is relying on and hereby incorporates its response to the NRDC petition. (See 73 FR 64229).

Regulatory Assessment Requirements
As indicated previously, this action announces the Agency's order denying a petition filed, in part, under section 408(d) of FFDCA. As such, this action is an adjudication and not a rule. The regulatory assessment requirements

imposed on rulemaking do not, therefore, apply to this action.

Submission to Congress and the Comptroller General
The Congressional Review Act, (5 U.S.C. 801 et seq.), as added by the Small Business Regulatory Enforcement Fairness Act of 1996, does not apply because this action is not a rule for purposes of 5 U.S.C. 804(3).
