2. Request for Additional Comment

   1. What action is the agency taking?

      In this notice, EPA is requesting additional comment on several issues that were raised in comments on EPA's proposed resolution of objections and a stay request with regard to sulfuryl fluoride and fluoride tolerances promulgated in 2004 and 2005 under section 408(d) of the Federal Food, Drug, and Cosmetic Act (FFDCA). (January 19, 2011, 76 FR 3422). In that notice, EPA proposed to grant the objections to the tolerances based on a conclusion that aggregate exposure to fluoride (from all sources including drinking water, dental products, and food) does not meet the safety standard in FFDCA section 408, although EPA notes that fluoride exposure that occurs as a result of sulfuryl fluoride use accounts for a relatively small portion of overall aggregate exposure (approximately 3 to 4 percent of total fluoride exposure). In the notice, EPA proposed to withdraw the sulfuryl fluoride and fluoride tolerances under an implementation schedule that would provide time for sulfuryl fluoride users to transition to new pest control alternatives. The notice also specified that the proposed tolerance withdrawal, if finalized, would become effective 60 days from the date of the final order, and would follow the implementation schedule detailed in the final order. EPA notes that during the pendency of the Agency's consideration of the objections to the sulfuryl fluoride and fluoride tolerances, the tolerances remain in effect. Neither the January 2011 proposed order nor this notice constitute final agency action.

   2. What is the agency's authority for taking this action?

      The procedure for filing objections to tolerance actions and EPA's authority for acting on such objections is contained in section 408(g) of FFDCA (21 U.S.C. 346a(g) and regulations at 40 CFR part 178. That same authority governs hearing and stay requests.

   3. On what matters is EPA requesting additional comment?

      EPA is seeking additional comment in two general areas. First, several commenters argued that, as a legal matter, EPA had a greater degree of discretion in how to interpret the standard in section 408(b) than indicated by EPA's proposal. EPA believes a fuller discussion of these arguments would aid its decision-making. Second, EPA has been contacted by several organizations regarding their comments bearing on the availability of alternatives to sulfuryl fluoride and the impacts of removal of the sulfuryl fluoride and fluoride tolerances. In discussions with these organizations, EPA noted that additional documentation was needed to support assertions made in the comments in question. In light of this, as well as due to the importance of this action, EPA has surveyed the comments and identified several issues related to availability of alternatives and impacts from withdrawal of the sulfuryl fluoride and fluoride tolerances that were raised by one or more commenters but were not always sufficiently documented. EPA is reopening the comment period to allow all commenters or others to provide additional information on the following issues.

      1. Legal issues. There are three legal issues that EPA believes warrant comment: whether the de minimis doctrine is applicable here given the limited fluoride exposure from pesticidal sources; whether EPA's aggregation of exposure to a pesticide and other related substances can include non-pesticidal substances, especially where pesticidal exposure is proportionally small compared to exposure to related substances; and whether EPA's obligations under other statutory authority should be considered in implementing FFDCA section 408.

         i. De minimis doctrine. Several commenters have asserted that EPA's proposed action would lead to absurd and undesirable consequences because removing the sulfuryl fluoride and fluoride tolerances will result in no greater than a minimal reduction in fluoride exposure but could have major impacts with regard to pest control for various stored commodities as well as complicating compliance by the United States with its obligations under the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol) and Title VI of the Clean Air Act (CAA) addressing Stratospheric Ozone Protection. In fact, Dow AgroSciences LLC argues that ``if sulfuryl fluoride were not in use as a fumigant, there would be no change in the number of children in the U.S. currently exposed to excessive levels of fluoride * * *.'' (EPA-

         HQ-OPP-2005-0174-0228).

         In brief, these commenters are objecting to the fluoride exposures EPA has taken into account in assessing fluoride risk under FFDCA section 408. Under that provision, 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)). ``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)). Other provisions in section 408 enlarge on the obligation to aggregate and cumulate exposures to the pesticide as well as other related substances. See 21 U.S.C. 346a(b)(2)(C)(i)(III) (requiring assessment of risk to infants and children based on cumulative effects of the pesticide and other substances that have a common mechanism of toxicity), 346a(b)(2)(D)(v) (requiring consideration of cumulative effects of the pesticide and other substances that have a common mechanism of toxicity), 346a(b)(2)(D)(vi) (requiring consideration of aggregate exposure to the pesticide and other related substances). In implementing this safety standard for the sulfuryl fluoride and fluoride tolerances, EPA has summed fluoride exposures from all sources, not just pesticidal sources, in evaluating the safety of the tolerances. The commenters have challenged this approach arguing that the de minimis doctrine would allow EPA to soften its approach to the aggregation of fluoride exposures and thus avoid potentially absurd consequences. As to absurd results, Dow AgroSciences LLC notes the ``insignificant exposure profile of sulfuryl fluoride, the adverse impacts on public health that would follow its elimination, and the de minimis treatment that EPA has afforded sources of similar amounts of fluoride exposure.''

         Under the de minimis doctrine, an agency need not apply the language of the statute in a literal manner if this leads to ``patently absurd results that will undermine Congress' broader purposes,'' Public Citizen v. FTC, 869

         Page 25663

         F.2d 1541, 1557 n. 33 (D.C. Cir. 1989), and the covered matter can ``fairly be considered de minimis,'' Alabama Power Co. v. Costle, 636 F.2d 323, 360 (D.C. Cir. 1979). Essential to exercise of a de minimis exception is that Congress cannot have been ``extraordinarily rigid,'' Alabama Power Co. v. Costle, 636 F.2d at 360; the exception cannot ``thwart a statutory command; it must be interpreted with a view to `implementing the legislative design;' '' Public Citizen v. Young, 831 F.2d 1108, 1113 (D.C. Cir. 1987) (quoting Alabama Power Co. v. Costle, 636 F.2d at 360-61); and regulation under the terms of the statute must ``yield a gain of trivial or no value,'' Alabama Power Co. v. Costle, 636 F.2d at 360-61. See EDF v. EPA, 82 F.3d 451, 466-467 (D.C. Cir. 1996); Ohio v. EPA, 997 F.2d 1520, 1534-35 (D.C. Cir. 1993).

         EPA seeks comment on how, if at all, the three elements of the de minimis doctrine would apply in the context of EPA's proposal to withdraw the sulfuryl fluoride and fluoride tolerances. First, has Congress imposed the aggregation requirement with extraordinary rigidity? In responding to this question it would be helpful if commenters would address the numerous references in FFDCA section 408 to the aggregation and cumulation of exposures, including the multiple references to the aggregation and cumulation of exposures to pesticides and other substances. See 21 U.S.C. 346a(b)(2)(C)(i)(III), 346a(b)(2)(D)(v), and 346a(b)(2)(D)(vi). Second, does not aggregating fluoride from pesticidal and non-pesticidal sources thwart or implement the statutory design? In other words, is the withdrawal of the sulfuryl fluoride and fluoride tolerances a ``patently absurd result'' that would thwart purposes of FFDCA section 408 or does it implement the statutory design? Finally, does fluoride exposure from pesticides truly amount to no greater than a de minimis risk? In approaching this question, it should be considered that EPA's risk assessments show that for the most highly exposed communities, total pesticidal fluoride amounts are approximately 3 to 4 percent of total fluoride exposure and 2 to 8 percent of the fluoride reference dose (RfD), depending on the age groups considered. See Kentucky Waterways Alliance v. Johnson, 540 F.3d 466, 492 (6th Cir. 2008). More broadly, any decision regarding whether fluoride exposure from pesticides is de minimis would potentially be precedential regarding other pesticides, and thus EPA requests comment generally on what factors should be considered in determining whether a pesticide's contribution to aggregate exposure is de minimis.

         ii. Exposure to other related substances. FIFRA section 408(b)(1)(A)(ii) defines the safety finding for the establishment of tolerances as requiring a determination 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.'' FIFRA section 408(b)(2)(D)(vi) requires EPA in establishing tolerances to ``consider, among other relevant factors * * * available information concerning the aggregate exposure of consumers (and major identifiable subgroups of consumers) to the pesticide chemical and to other related substances * * *.'' Dow AgroSciences LLC argues (1) that the ``other related substances'' referenced in FIFRA section 408(b)(2)(D)(vi) are only other related pesticidal substances; and (2) that, even if the term ``other related substances'' includes non-pesticidal substances, aggregation of pesticide alone must have a ``meaningful impact on the end point of concern.'' EPA requests comment on whether such an interpretation is consistent with the language of these two provisions, as well as the other provisions of the statute that discuss aggregation and cumulation of pesticides and other related substances. See 21 U.S.C. 346a(b)(2)(C)(i)(III), 346a(b)(2)(D)(v).

         iii. Reconciling all environmental statutes and treaty obligations. The Natural Resources Defense Council (NRDC) argues in its comments that EPA has an obligation to reconcile its action on sulfuryl fluoride under FFDCA section 408 with its duties under the Clean Air Act and the Montreal Protocol relating to the phase-out of methyl bromide. (EPA-HQ-

         OPP-2005-0174-0150). Specifically, NRDC asserts that EPA must consider the ``full range of the health consequences of its actions'' under FFDCA section 408. EPA requests comment on whether the presence of other statutory duties would allow EPA to approve a pesticide tolerance that was otherwise unsafe under FFDCA section 408, if failing to approve the tolerance would lead to greater net damages to the environment. In responding to this question, commenters should address FFDCA section 408(b)(2)(B) that describes the circumstances under which EPA may take such health-health tradeoffs into account. Also, EPA requests comment on the question of what are the ``full range of the health consequences'' of withdrawing the sulfuryl fluoride and fluoride tolerances. If EPA were to accept NRDC's legal premise, the facts surrounding the ``range of health consequences'' would be important to any EPA decision.

      2. Alternatives and impacts. EPA has identified several issues related to availability of alternatives and impacts from withdrawal of the sulfuryl fluoride and fluoride tolerances that were raised by one or more commenters but were not always sufficiently documented. EPA would recommend commenters consider the following descriptions of the types of documentation that would aid EPA in compiling adequate record materials on the issues in question:

         i. Please provide complete and accurate references (i.e., peer-

         reviewed articles, personal contacts, consultants, other) for any and all data and information included, mentioned, referred to, and/or cited in comments. For example, provide sources of information for costs of heat treatment, costs of construction, phosphine resistance, phosphine corrosion, efficacy of alternatives, etc. Any information relied on to make any inference, reach a conclusion, or derive a quantitative estimate should be accompanied by a complete and accurate reference. Some of the commenters already provided references for their information; others did not. Please note that without accurate references, the Agency may not be able to locate the information to update and/or revise impacts where appropriate.

         ii. If cost estimates for warehouse construction, fumigation chamber construction, or other types of construction were included in a comment, please provide the full details of the calculations and all assumptions used to derive the estimates, and please provide a contact name and number for the person or company that created the estimates, in case the Agency has further questions.

         iii. Regarding the corrosive effects of phosphine to equipment, what types of machines are damaged by phosphine, what is the nature of the damage, how many phosphine treatments does it take to damage them, how much does the equipment cost, and, if possible, how could the equipment be moved or retrofitted so that the damage does not occur?

         iv. Please provide complete and accurate references to any law or regulation on food safety cited in a comment. For example, some comments mentioned mandatory fumigation, pasteurization, etc. of food products. Please provide specific references to any

         Page 25664

         and all statutes and/or regulations that require such treatments.

         v. Several applicators mentioned that sulfuryl fluoride was safer than phosphine for applicators. Please explain why sulfuryl fluoride application is safer, using specific examples where possible.

         vi. Several comments mentioned the inability of heat to penetrate finished product. Please contrast this with the ability for fumigant gas to penetrate the products.

         vii. If any specific customer requests for fumigation to address a particular pest infestation are mentioned in a comment, please provide examples of those requests.

         viii. If any claims are made that sulfuryl fluoride is needed so that food can meet phytosanitary conditions in foreign markets, please provide examples of those requirements (e.g., import requirements of other countries), please explain why quarantine methyl bromide cannot be used to meet the requirements, and please provide details on the pounds of product fumigated with sulfuryl fluoride for export each year to countries with these requirements.

         ix. Many comments from groups that process and store commodities, such as nuts and dried fruit, noted that there was a need for fast turnaround times in fumigation to meet market demand. If the industry never requested a methyl bromide critical use exemption, please explain how fast fumigation was conducted prior to the introduction of sulfuryl fluoride, why the transition to sulfuryl fluoride occurred, and why it would now not be possible to switch back to previous methods. Several comments indicated that there would be human health concerns from lack of an effective fumigant. If available, please provide specific examples (with complete and accurate references) of public health issues caused by lack of fumigants.

         x. As to claims that there are commercially viable, chemical or non-chemical, alternatives for commodities and/or structures, please provide literature citations and/or personal contacts for the efficacy of these alternatives and the costs and technical feasibility of transition. In addition, please provide any available information on how using the alternatives is expected to affect the cost of the end product.

         xi. As to claims that pest problems for which U.S. industries currently employ sulfuryl fluoride are successfully controlled in countries where neither sulfuryl fluoride nor methyl bromide is used, please provide data, literature citations and/or personal contacts for the efficacy and costs of these chemical or non-chemical alternatives.

         xii. As to claims of economic or other types of impacts as a result of EPA's proposed order, recognizing that EPA has not yet issued a final order or taken final agency action, please provide specific information, data, and/or personal contacts to substantiate these claims.

10. Regulatory Assessment Requirements

    This notice seeks additional comment on the Agency's proposed order regarding objections filed under section 408 of FFDCA. The proposed order is part of an adjudication and not a rule. The regulatory assessment requirements imposed on rulemaking do not, therefore, apply to this notice.

11. 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 to this notice because this is not a rule for purposes of 5 U.S.C. 804(3).
