                    **Federal Register**
                     of December 22, 2010 (75 FR 80489) (FRL-8857-8), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide petition (PP 9E7517) by Dow AgroSciences, 9330 Zionsville Rd., Indianapolis, IN 46268. The petition requested that 40 CFR part 180 be amended by establishing permanent tolerances for residues of the herbicide safener dichlormid, N,N-diallyl-2,2-dichloroacetamide, in or on corn, field, forage; corn, field, grain; corn, field, stover; corn, pop, grain; corn, pop, stover; corn, sweet, forage; corn, sweet, kernel plus cob with husks removed; and corn, sweet, stover at 0.05 parts per million (ppm). That notice referenced a summary of the petition prepared by Dow AgroSciences, the registrant, which is available in the docket, 
                    *http://www.regulations.gov.*
                     Comments were received on the notice of filing. EPA's response to these comments is discussed in Unit IV.C. III. Aggregate Risk Assessment and Determination of Safety Section 408(b)(2)(A)(i) of 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 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 
                    ( print page 16309)
                    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 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.” Consistent with section 408(b)(2)(D) of FFDCA, and the factors specified in section 408(b)(2)(D) of 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 for dichlormid including exposure resulting from the tolerances established by this action. EPA's assessment of exposures and risks associated with dichlormid follows. In the 
                    **Federal Register**
                     of March 27, 2000 (65 FR 16143) (FRL-6498-7), EPA published a final rule establishing time-limited tolerances for residues of the herbicide safener dichlormid in or on field corn forage, grain and stover; and pop corn grain and stover at 0.05 ppm. In the 
                    **Federal Register**
                     of September 30, 2004 (69 FR 58285) (FRL-7680-8), EPA published a final rule establishing time-limited tolerances for residues of dichlormid in or on sweet corn forage, kernel plus cob with husks removed, and stover at 0.05 ppm. EPA has extended the expiration date of the time-limited tolerances on several occasions, most recently in the 
                    **Federal Register**
                     of July 29, 2009 (74 FR 37621) (FRL-8422-2). The tolerances expired on December 31, 2010. The corn tolerances were time-limited due to an incomplete database for dichlormid. Data gaps included several chemistry and toxicology studies, as identified in the March 27, 2000 and September 30, 2004 final rules. In addition, in December, 2007, EPA began requiring functional immunotoxicity testing of all food and non-food use pesticides (40 CFR part 158, subpart F), including safeners, such as dichlormid. The outstanding chemistry and toxicology data (including immunotoxicity testing) have all been submitted and reviewed, so that the database for dichlormid is now considered complete. No changes in tolerance levels or toxicological endpoints and doses used in the human health risk assessment for dichlormid are needed as a result of the new data. Copies of EPA's reviews of these data may be found in docket ID number EPA-HQ-OPP-2005-0477. The risk assessments that EPA relied on in establishing and extending the time-limited tolerances for dichlormid were highly conservative. Due to the nature and number of data gaps and qualitative evidence of increased susceptibility of 
                    *in utero*
                     rabbits in a prenatal developmental toxicity study, the FQPA safety factor (SF) was retained at 10X for the acute dietary risk assessment and increased to 30X for the chronic dietary risk assessment. Since the data gaps have been filled, uncertainty factors associated with database deficiencies may be removed. In addition, EPA used tolerance level residues, 100 percent crop treated, and default processing factors in the dietary food exposure assessments and made conservative (protective) assumptions in the modeling used to assess exposure to dichlormid in drinking water. Using these highly conservative assumptions and SFs, acute dietary exposure to dichlormid in food was estimated to be less than or equal to 7.5% of the acute population adjusted dose (aPAD) for all population subgroups; chronic dietary exposure to dichlormid in food was estimated to be less than or equal to 15% of the chronic population adjusted dose (cPAD) for all populations subgroups. Because this prior risk assessment showed dichlormid risks to be acceptable and the effect of submission of the required data on the assessment of dichlormid risk will be to lower estimated risks (due to the removal of additional safety factors), EPA is relying on that prior risk assessment and the findings in the prior dichlormid FR notices, subject to one modification, to demonstrate the safety of the tolerances established in this action. The one modification of the prior risk assessment and FR notices is to update how exposure to dichlormid in drinking water is factored into the risk assessment. Previously, EPA assessed aggregate exposure (food and drinking water) to dichlormid using the DWLOC (drinking water level of comparison) approach. The DWLOC is the concentration of a chemical in drinking water that would be acceptable as an upper limit considering total aggregate exposure to that chemical from food, water, and residential sources. In this case, there are no residential uses of dichlormid. Acute and chronic aggregate risks from dichlormid exposure were assessed by comparing the calculated DWLOCs to the estimated environmental concentrations (EECs) of dichlormid in surface water and groundwater. Since the EECs (< 1 ppm in both surface and groundwater) were well below the calculated DWLOCs for acute exposure (73 parts per billion (ppb)) and chronic exposure (20 ppb), acute and chronic aggregate risks were determined to be below the Agency's level of concern. Details of the risk assessment for dichlormid may be found in the document “Human Health Risk Assessment for Dichlormid-Request for Establishing Permanent Tolerances for Dichlormid on Corn,” which is available in docket ID number EPA-HQ-OPP-2005-0477. The Agency no longer uses the DWLOC approach for assessing aggregate exposure to pesticides. Rather, estimated drinking water concentrations (EDWCs) are directly entered into the dietary exposure model to assess the contribution of drinking water exposure to aggregate exposure. EPA then determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the aPAD and cPAD. Using this approach, together with the conservative assumptions and SFs discussed earlier in this unit, EPA has concluded that acute and chronic exposure to dichlormid from food and water will utilize 56% of the aPAD and 34% of the cPAD for infants, less than one year old, the population group receiving the greatest exposure. Based on the prior and updated risk assessments as well as the findings in the prior dichlormid FR notices, EPA concludes that there is a reasonable certainty that no harm will result to the general population, or to infants and children from aggregate exposure to dichlormid residues. IV. Other Considerations A. Analytical Enforcement Methodology Adequate enforcement methodology (gas chromatography with nitrogen selective thermionic detection) is available to enforce the tolerance expression. 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 In making its tolerance decisions, EPA seeks to harmonize U.S. tolerances with international standards whenever possible, consistent with U.S. food safety standards and agricultural practices. EPA considers the international maximum residue limits 
                    ( print page 16310)
                    (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). The Codex Alimentarius is a joint U.N. Food and Agriculture Organization/World Health Organization food standards program, and it is recognized as an international food safety standards-setting organization in trade agreements to which the United States is a party. EPA may establish a tolerance that is different from a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain the reasons for departing from the Codex level. The Codex has not established a MRL for dichlormid in or on corn commodities. C. Response to Comments An anonymous comment was received objecting to the presence of any pesticide residue on food. The Agency understands the commenter's concerns and recognizes that some individuals believe that pesticides should be banned completely. However, the existing legal framework provided by section 408 of the FFDCA contemplates that tolerances greater than zero may be set when persons seeking such tolerances or exemptions have demonstrated that the pesticide meets the safety standard imposed by that statute. This citizen's comment appears to be directed at the underlying statute and not EPA's implementation of it; the citizen has made no contention that EPA has acted in violation of the statutory framework. D. Revisions to Petitioned-for Tolerances EPA is revising the requested tolerance expression to clarify the chemical moieties that are covered by the tolerances and specify how compliance with the tolerances is to be measured. The revised tolerance expression makes clear that the tolerances cover residues of the herbicide safener dichlormid, including its metabolites and degradates, but that compliance with the tolerances is to be determined by measuring only dichlormid (2,2-dichloro-
                    *N,N*
                    -di-2-propenylacetamide). EPA has determined that it is reasonable to make this change final without prior proposal and opportunity for comment, because public comment is not necessary, in that the change has no substantive effect on the tolerance, but rather is merely intended to clarify the existing tolerance expression. V. Conclusion Therefore, tolerances are established for residues of dichlormid, including its metabolites and degradates, in or on corn, field, forage; corn, field, grain; corn, field, stover; corn, pop, grain; corn, pop, stover; corn, sweet, forage; corn, sweet, kernel plus cob with husks removed; and corn, sweet, stover at 0.05 ppm. Compliance with the tolerances is to be determined by measuring only dichlormid (2,2-dichloro-
                    *N,N*
                    -di-2-propenylacetamide). VI. Statutory and Executive Order Reviews This final rule establishes tolerances under section 408(d) of 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 final rule has been exempted from review under Executive Order 12866, this final 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) or Executive Order 13045, entitled 
                    *Protection of Children from Environmental Health Risks and Safety Risks*
                     (62 FR 19885, April 23, 1997). 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.,*
                     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). Since tolerances and exemptions that are established on the basis of a petition under section 408(d) of 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. This final rule directly regulates growers, food processors, food handlers, and food retailers, not States or tribes, nor does this action alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of FFDCA. As such, the Agency has determined that this action will not have a substantial direct effect on States or tribal governments, on the relationship between the national government and the States or tribal governments, or on the distribution of power and responsibilities among the various levels of government or between the Federal Government and Indian tribes. Thus, the Agency has determined that Executive Order 13132, entitled 
                    *Federalism*
                     (64 FR 43255, August 10, 1999) and Executive Order 13175, entitled 
                    *Consultation and Coordination with Indian Tribal Governments*
                     (65 FR 67249, November 9, 2000) do not apply to this final rule. In addition, this final rule does not 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). 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). VII. Congressional Review Act The Congressional Review Act, 5 U.S.C. 801
                    *et seq.,*
                     generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report 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). List of Subjects in 40 CFR Part 180 Environmental protection
