II. Background and Statutory Findings

In the Federal Register of July 9, 2003 (68 FR 40939) (FRL-7314-1), EPA issued a notice pursuant to section 408 of FFDCA, 21 U.S.C. 346a, as amended by FQPA (Public Law 104-170), announcing the filing of pesticide petitions (PP 2E6419, PP 1E6306, PP 1E6270, PP 1E6337, PP 9E5082, PP 0E6199, and PP 1E6292) by IR-4, 681 U. S. Highway #1 South, North Brunswick, NJ 08902-3390. That notice included a summary of the petitions prepared by the registrant, HACO, Inc., P.O. Box 7190, Madison, WI 53707. The Agency received a number of comments on the notice of filing published on July 9, 2003 (68 FR 40939). All comments were in favor of establishing the food tolerances proposed in the notice.

The petitions requested that 40 CFR 180.284 be amended by establishing tolerances for residues of phosphine resulting from the use of the rodenticide zinc phosphide, in or on alfalfa, forage and alfalfa, hay at 0.1 parts per million (ppm); barley, grain and barley, hay at 0.05 ppm, and barley, straw at 0.2 ppm; bean, dry at 0.05 ppm; beet, sugar, roots at 0.05 ppm and beet, sugar, tops at 0.2 ppm; potato at 0.05 ppm; timothy, forage and timothy, hay at 0.05 ppm; and wheat, grain, wheat, hay, and wheat, straw at 0.05 ppm.

EPA is also deleting several established tolerances in § 180.284(b) that are no longer needed, as a result of this action. The tolerance deletions are time-limited tolerances established under section 18 emergency exemptions that are superceded by the establishment of general tolerances for zinc phosphide under § 180.284(a).

The following deletions to § 180.284(b) are replaced in § 180.284(a):

1. Delete the time-limited tolerances for barley, grain at 0.01 ppm, barley, hay at 0.20 ppm, and barley straw at 0.02 ppm. Tolerances for barley, grain at 0.05 ppm, barley, hay at 0.2 ppm, and barley, straw at 0.2 ppm are established by this action under § 180.284(a).

2. Delete the time-limited tolerances for beet, sugar, roots at 0.05 ppm and beet, sugar, tops at 0.1 ppm. Tolerances for sugar, beet, roots are established at 0.05 ppm and sugar, beet, tops at 0.2 ppm under § 180.284(a).

3. Delete the time-limited tolerance for potato at 0.05 ppm. A tolerance for potato is established at 0.05 ppm under § 180.284(a).

4. Delete the time-limited tolerances for timothy, forage and timothy, hay at 0.1 ppm. Tolerances for timothy, forage and timothy, hay are established at 0.5 ppm under § 180.284(a).

5. Delete the time-limited tolerances for wheat, grain, wheat, hay and wheat, straw at 0.01 ppm. Tolerances for wheat, grain, wheat, hay, wheat, straw, and wheat, forage are established at 0.05 ppm under § 180.284(a).

Section 408(b)(2)(A)(i) of the FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is “safe.” Section 408(b)(2)(A)(ii) of the FFDCA defines “safe” 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.” This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Section 408(b)(2)(C) of the FFDCA requires EPA to give special consideration to exposure of infants and children to the pesticide chemical residue in establishing a tolerance and to “ensure that there is a reasonable certainty that no harm will result to infants and children from aggregate exposure to the pesticide chemical residue. . . .”

EPA performs a number of analyses to determine the risks from aggregate exposure to pesticide residues. For further discussion of the regulatory requirements of section 408 of the FFDCA and a complete description of the risk assessment process, see the final rule on Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997) (FRL-5754-7).

III. Aggregate Risk Assessment and Determination of Safety

Consistent with section 408(b)(2)(D) of the FFDCA, EPA has reviewed the available scientific data and other relevant information in support of this action. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure, consistent with section 408(b)(2) of the FFDCA, for tolerances for residues of phosphine resulting from the use of the rodenticide zinc phosphide on alfalfa, forage and alfalfa, hay at 0.2 ppm; barley, grain at 0.05; barley, hay at 0.2 ppm; barley, straw at 0.2 ppm; bean, dry, seed at 0.05 ppm; beet, sugar, roots at 0.05 ppm; beet, sugar, tops at 0.2 ppm; potato at 0.05 ppm; timothy, forage and timothy, hay at 0.5 ppm; and wheat, forage, wheat, grain, wheat hay, and wheat, straw at 0.05 ppm. EPA's assessment of exposures and risks associated with establishing the tolerances follows.

A. Toxicological Profile

EPA has evaluated the available toxicity data and considered its validity, completeness, and reliability as well as the relationship of the results of the studies to human risk. EPA has also considered available information concerning the variability of the sensitivities of major identifiable subgroups of consumers, including infants and children. The nature of the toxic effects caused by zinc phosphide are discussed in Table 1 of this unit as well as the no observed adverse effect level (NOAEL) and the lowest observed adverse effect level (LOAEL) from the toxicity studies reviewed.

B. Toxicological Endpoints

The dose at which no adverse effects are observed (the NOAEL) from the toxicology study identified as appropriate for use in risk assessment is used to estimate the toxicological level of concern (LOC). However, the lowest dose at which adverse effects of concern are identified (the LOAEL) is sometimes used for risk assessment if no NOAEL was achieved in the toxicology study selected. An uncertainty factor (UF) is applied to reflect uncertainties inherent in the extrapolation from laboratory animal data to humans and in the variations in sensitivity among members of the human population as well as other unknowns. An UF of 100 is routinely used, 10X to account for interspecies differences and 10X for intraspecies differences.

For dietary risk assessment (other than cancer) the Agency uses the UF to calculate an acute or chronic reference dose (acute RfD or chronic RfD) where the RfD is equal to the NOAEL divided by the appropriate UF (RfD = NOAEL/UF). Where an additional safety factors (SF) is retained due to concerns unique to the FQPA, this additional factor is applied to the RfD by dividing the RfD by such additional factor. The acute or chronic Population Adjusted Dose (aPAD or cPAD) is a modification of the RfD to accommodate this type of FQPA SF.

For non-dietary risk assessments (other than cancer) the UF is used to determine the LOC. For example, when 100 is the appropriate UF (10X to account for interspecies differences and 10X for intraspecies differences) the LOC is 100. To estimate risk, a ratio of the NOAEL to exposures (margin of exposure (MOE) = NOAEL/exposure) is calculated and compared to the LOC.

The linear default risk methodology (Q*) is the primary method currently used by the Agency to quantify carcinogenic risk. The Q* approach assumes that any amount of exposure will lead to some degree of cancer risk. A Q* is calculated and used to estimate risk which represents a probability of occurrence of additional cancer cases (e.g., risk is expressed as 1 x 10-6 or one in a million). Under certain specific circumstances, MOE calculations will be used for the carcinogenic risk assessment. In this non-linear approach, a “point of departure” is identified below which carcinogenic effects are not expected. The point of departure is typically a NOAEL based on an endpoint related to cancer effects though it may be a different value derived from the dose response curve. To estimate risk, a ratio of the point of departure to exposure (MOEcancer = point of departure/exposures) is calculated. A summary of the toxicological endpoints for zinc phosphide used for human risk assessment is shown in Table 2 of this unit:Start Printed Page 56192

C. Exposure Assessment

1. Dietary exposure from food and feed uses. Tolerances have been established (40 CFR 180.284(a)) for residues of phosphine resulting from the use of zinc phosphide, in or on a variety of raw agricultural commodities including: Grape (0.01 ppm), grass (rangeland) (0.1 ppm), and sugarcane (0.01 ppm). Tolerances with regional registration are established 40 CFR 180.284(c) for zinc phosphide residues in or on globe artichokes (0.01 ppm), sugar beet (roots) (0.04 ppm), and sugar beet tops (0.02 ppm). Section 18 tolerances at 40 CFR 180.284(b) currently exist for zinc phosphide residues in or on: Alfalfa forage, alfalfa hay, barley grain, barley hay, barley straw, sugar beets (tops), sugar beet roots, timothy, hay, timothy, forage, potato, wheat grain, wheat hay, and wheat straw.

Based on residue data from field trials conducted in support of the subject tolerances, EPA concludes that acute and chronic dietary exposure associated with the proposed uses of zinc phoshide is unlikely. Residues were below the Level of Quantitation (LOQ) (<0.05 or <0.1 ppm) in crops, except for the livestock feed items alfalfa forage, sugar beet tops, and timothy forage. Alfalfa forage, sugar beet tops, and timothy hay are not direct human food items; rather, they are used as animal feeds. Because residues of zinc phosphide ingested by livestock would be immediately converted to phosphine and metabolized to naturally occurring phosphorus compounds, residues of zinc phosphide in livestock feeds are not expected to result in residues of zinc phosphide in livestock commodities. Also, the act of processing and washing will not allow for unreacted zinc phosphide to remain in or on food items. In addition, residues are not expected in wheat and barley grain since zinc phosphide will be applied to barley and wheat prior to the formation of seed heads.

2. Dietary exposure from drinking water. No drinking water risk assessment was performed for zinc phosphide because no residues are expected in either ground water or surface water.

3. From non-dietary exposure. The term “residential exposure” is used in this document to refer to non-occupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets).

Zinc phosphide is currently registered in pellet and bait form for use on residential non-food sites to control mammals (primarily rodents) in areas such as commercial establishments, public areas (parks), dumps, and homes. A detailed residential exposure assessment is contained in the Reregistration Eligibility Decision (RED) Document, EPA 738-R-98-006, July 1998, for zinc phosphide.

There were no endpoints identified for zinc phosphide use in a residential assessment except for accidental ingestion. The residential exposure assessment evaluated exposure from accidental ingestion of zinc phosphide. No other residential exposure assessment was either expected or, if expected, found to have any hazard potential.

Although having considered that accidental ingestion of zinc phosphide baits may occur with respect to a very small number of children, EPA has concluded that this potential exposure is not appropriate for inclusion in evaluating the safety of aggregate exposure of consumers and major identifiable subgroups of consumers to zinc phosphide. Unlike other residential uses (such as a turf use) that potentially may result in exposures to significant groups of children, the subgroup of children that may consume baits in childproof bait stations is very tiny. This small subgroup of children would not qualify as a major identifiable subgroup of consumers.

4. Cumulative effects from substances with a common mechanism of toxicity. Section 408(b)(2)(D)(v) of the FFDCA requires that, when considering whether to establish, modify, or revoke a tolerance, the Agency consider “available information” concerning the cumulative effects of a particular Start Printed Page 56193pesticide's residues and “other substances that have a common mechanism of toxicity.”

EPA does not have, at this time, available data to determine whether zinc phosphide has a common mechanism of toxicity with other substances. Unlike other pesticides for which EPA has followed a cumulative risk approach based on a common mechanism of toxicity, EPA has not made a common mechanism of toxicity finding as to zinc phosphide and any other substances, and zinc phosphide does not appear to produce a toxic metabolite produced by other substances. For the purposes of this tolerance action, therefore, EPA has not assumed that zinc phosphide has a common mechanism of toxicity with other substances. For information regarding EPA's efforts to determine which chemicals have a common mechanism of toxicity and to evaluate the cumulative effects of such chemicals, see the policy statements released by EPA's Office of Pesticide Programs concerning common mechanism determinations and procedures for cumulating effects from substances found to have a common mechanism on EPA's website at http://www.epa.gov/​pesticides/​cumulative/​.

D. Safety Factor for Infants and Children

1. In general. Section 408 of the FFDCA provides that EPA shall apply an additional tenfold margin of safety for infants and children in the case of threshold effects to account for prenatal and postnatal toxicity and the completeness of the data base on toxicity and exposure unless EPA determines that a different margin of safety will be safe for infants and children. Margins of safety are incorporated into EPA risk assessments either directly through use of a MOE analysis or through using uncertainty (safety) factors in calculating a dose level that poses no appreciable risk to humans.

3. Conclusion. EPA has waived a significant portion of the data normally required in establishing a tolerance for a pesticide chemical, in evaluating the petitions for zinc phosphide. This data waiver is based on data showing that dietary exposure is unlikely to result from agricultural uses of zinc phosphide. Based on these exposure data, EPA concludes there are reliable data supporting a conclusion that no additional safety factor is necessary to protect the safety of infants and children.

E. Aggregate Risks and Determination of Safety

Zinc phosphide has both food and non-occupational uses; therefore, the considerations for aggregate exposure are those from food, drinking water, and residential (non-occupational) sources.

The Agency has concluded that there will be no human dietary exposure from the proposed or registered uses of zinc phosphide. Thus, exposure to zinc phosphide from food is not a component of the acute and chronic aggregate exposure assessment.

1. Acute risk. The Agency has concluded that there will be no human dietary exposure from the proposed or registered uses of zinc phosphide. Thus, exposure to zinc phosphide from food is not a component of the acute and chronic aggregate exposure assessment.

2. Chronic risk. The Agency has concluded that there will be no human dietary exposure from the proposed or registered uses of zinc phosphide. Exposure to zinc phosphide from food and water is not a component of the acute and chronic aggregate exposure assessment

.

There are no residential uses for zinc phosphide that result in chronic residential exposure to zinc phosphide. Based on the use pattern, chronic residential exposure to residues of zinc phosphide is not expected. There is no potential for chronic dietary exposure to zinc phosphide in food and drinking water.

3. Short-term and intermediate-term risk. Short-term and intermediate-term aggregate exposure takes into account chronic dietary food and water (considered to be a background exposure levels) plus indoor and outdoor residential exposure. No short-term or intermediate-term dermal, oral or inhalation toxicological endpoints were identified for zinc phosphide.

Further, no incidental oral exposure is expected given the conditions of use. Although potentially accidental ingestion of zinc phosphide bait may occur in rare instances, the subgroup of children that are exposed in such a manner is not a major identifiable subgroup of consumers.

4. Aggregate cancer risk for U.S. population. Since chronic exposure and risk associated with the use of zinc phosphide is negligible, no risk of cancer is expected from the use of zinc phosphide.

5. Determination of safety. There is no drinking water, residential, nor dietary component to acute and chronic aggregate exposure to zinc phosphide residues. Based on these exposure assessments, EPA concludes that there is a reasonable certainty that no harm will result to adults, infants and children from aggregate exposure to zinc phosphide residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

Acceptable methods are available for enforcement and data collection purposes for plant commodities. The Pesticide Analytical Manual (PAM), Vol. II lists, under aluminum phosphide, a colorimetric method and a gas liquid chromatography with flame photometric detection (GLC/FPD) method as Methods A and B, respectively. Both methods determine the level of phosphine liberated when zinc phosphide is exposed to dilute acid solutions. EPA has determined that Method A is acceptable for enforcement. Data submitted in support of the established tolerances were collected by one of these two methods. Data submitted in support of the proposed tolerances were collected by the GLC/FPD method or a similar method

The method may be requested from: Chief, Analytical Chemistry Branch, Environmental Science Center, 701 Mapes Rd., Ft. Meade, MD 20755-5350; telephone number: (410) 305-2905; e-mail address: residuemethods@epa.gov.

B. International Residue Limits

There are no international harmonization issues associated with this action since there are no Codex, Mexican or Canadian maximum residue levels (MRLs) or tolerances for zinc phosphide on any crop.

V. Conclusion

Therefore, the tolerances are established for residues of phosphine resulting from the use of zinc phosphide in or on alfalfa, forage and alfalfa, hay at 0.2 ppm; barley, grain, at 0.05 ppm, barley, hay and barley, straw at 0.2 ppm; bean, dry, seed at 0.05 ppm; beet, sugar, roots at 0.05 ppm and beet, sugar, tops at 0.2 ppm; potato at 0.05 ppm; timothy, forage and timothy, hay at 0.5 ppm; and wheat, forage, wheat, grain, wheat hay, and wheat, straw at 0.05 ppm.

VI. Objections and Hearing Requests

Under section 408(g) of the FFDCA, as amended by the FQPA, any person may file an objection to any aspect of this regulation and may also request a hearing on those objections. The EPA procedural regulations which govern the submission of objections and requests for hearings appear in 40 CFR part 178. Although the procedures in those regulations require some modification to reflect the amendments made to the FFDCA by the FQPA, EPA will continue Start Printed Page 56194to use those procedures, with appropriate adjustments, until the necessary modifications can be made. The new section 408(g) of the FFDCA provides essentially the same process for persons to “object” to a regulation for an exemption from the requirement of a tolerance issued by EPA under new section 408(d) of FFDCA, as was provided in the old sections 408 and 409 of the FFDCA. However, the period for filing objections is now 60 days, rather than 30 days.

B. When Will the Agency Grant a Request for a Hearing?

A request for a hearing will be granted if the Administrator determines that the material submitted shows the following: There is a genuine and substantial issue of fact; there is a reasonable possibility that available evidence identified by the requestor would, if established resolve one or more of such issues in favor of the requestor, taking into account uncontested claims or facts to the contrary; and resolution of the factual issues(s) in the manner sought by the requestor would be adequate to justify the action requested (40 CFR 178.32).

VII. Statutory and Executive Order Reviews

This final rule establishes a tolerance under section 408(d) of the FFDCA in response to a petition submitted to the Agency. 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 rule has been exempted from review under Executive Order 12866 due to its lack of significance, this rule is not subject to Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001). This final 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) (Public Law 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 and exemptions that are established on the basis of a petition under section 408(d) of the FFDCA, such as the tolerance in this final 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. 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 Start Printed Page 56195responsibilities 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 final 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 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 6, 2000). Executive Order 13175, 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 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 specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this rule.

VIII. Congressional Review Act

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of this final rule in the Federal Register. This final rule is not a “major rule” as defined by 5 U.S.C. 804(2).
