That document referenced a summary of the petition prepared by ISK Biosciences Corporation, the registrant, which is available in the docket, https:// www.regulations.gov. One comment was received on the notice of filing. EPA’s response to this comment 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 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 FFDCA section 408(b)(2)(D), and the factors specified in FFDCA section 408(b)(2)(D), 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 flazasulfuron including exposure resulting from the tolerances established by this action. EPA’s assessment of exposures and risks associated with flazasulfuron follows. In an effort to streamline its publications in the Federal Register, EPA is not reprinting sections that repeat what has been previously published for tolerance rulemakings of the same pesticide chemical. Where scientific information concerning a particular chemical remains unchanged, the content of those sections would not vary between tolerance rulemakings, and republishing the same sections are unnecessary. EPA considers referral back to those sections as sufficient to provide an explanation of the information EPA considered in making its safety determination for the new rulemaking. EPA has evaluated the available toxicity data and considered its validity, VerDate Sep<11>2014 15:55 Oct 04, 2024 Jkt 262001 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. Specific information on the studies received and the nature of the toxic effects caused by flazasulfuron as well as the noobserved-adverse-effect-level (NOAEL) and the lowest-observed-adverse-effectlevel (LOAEL) from the toxicity studies can be found in Unit II.A, of the May 25, 2017, rulemaking. There are no changes to the prior endpoint selections from the 2015 Draft Risk Assessment for Registration Review. In that risk assessment some studies used for endpoint selection were judged to have conservative NOAEL/ LOAEL values because they were not updated to reflect current standards for evaluating toxicity studies. Such updates would likely result in higher NOAEL/LOAEL values and given the current risk picture, would not impact the overall findings of this risk assessment. Therefore, these studies were not re-evaluated in conjunction with this risk assessment. A detailed description of endpoint selection can be found at https://www.regulations.gov, ‘‘Flazasulfuron: Human Health Draft Risk Assessment for Registration Review, dated September 15, 2015. The acute and chronic dietary risk assessments for flazasulfuron are unrefined assessments which incorporate tolerance-level residues, 100% crop treated (CT), and modeled estimated drinking water concentrations (EDWCs). The processing factors were set to 1 for the processed commodities that are in table 1 (860.1000). A default processing factor was used for hazelnut. The results of acute dietary (food and drinking water) analysis are below the Agency’s level of concern (LOC) for all population subgroups. The acute dietary risk estimates utilized <1.0% of the acute population-adjusted dose (aPAD) for the general U.S. population and 3.3% of the aPAD for infants (<1 years old), the most highly exposed population subgroup. The results of chronic dietary (food and drinking water) analysis are below the Agency’s LOC for all population subgroups. The chronic dietary risk estimates utilized 8.8% of the chronic population-adjusted dose (cPAD) for the general U.S. population and 32% of the cPAD for infants (<1 years old), the most highly exposed population subgroup. Based on the data summarized in Unit III.A. of the May 25, 2017, rulemaking, EPA has concluded that flazasulfuron does not PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 81011 pose a cancer risk to humans. Therefore, a dietary exposure assessment for the purpose of assessing cancer risk is unnecessary. EDWCs from the previous drinking water assessment are considered protective of the new use and may be used to represent EDWCs for the proposed new use on avocados. EDWCs include total toxic residues of flazasulfuron (i.e., all of the degradates: DTPU, DTPP, HTPP, TPSA, ADMP, and 2,3–GTF). The highest EDWCs from the previous assessment were from ground water and were modeled using Pesticide Root Zone Model for Ground Water (PRZM–GW). EPA’s conclusions remain unchanged from Unit II. C.2 of the May 25, 2017, rulemaking. There is no residential exposure associated with the proposed use in this action; however, there is residential exposure from an existing registered use on turf that has been previously assessed using current data and assumptions for flazasulfuron. Risk estimates have been presented for the purpose of aggregate assessment; and conclude all residential risk estimates are not of concern. For more details, see Unit II.C.3 of the May 25, 2017, rulemaking. Further information regarding EPA standard assumptions and generic inputs for residential exposures may be found at https:// www.epa.gov/pesticide-science-andassessing-pesticide-risks/standardoperating-procedures-residentialpesticide. No further data are required to determine that no common mechanism of toxicity exists for flazasulfuron and other pesticides. As a result, no further cumulative evaluation is necessary for flazasulfuron as published in Unit II.C.4 of the May 25, 2017, rulemaking. The toxicity database for flazasulfuron is complete and adequate to assess susceptibility in the young. While there is evidence of increased qualitative and quantitative susceptibility in the young based on rat malformations and decreased fetal weight in two rat developmental toxicity studies, the Food Quality Protection Act (FQPA) Safety Factor (SF) is reduced to 1X and is protective of the observed offspring susceptibility because: (1) there are clear NOAELs for the developmental effects in the two rat studies developmental toxicity studies and the PODs selected for risk assessment are protective of those effects, (2) there is no evidence of neurotoxicity, and (3) exposure estimates are unlikely to underestimate risk. These conclusions are further discussed in Unit II.D of the May 25, 2017, rulemaking. E:\FR\FM\07OCR1.SGM 07OCR1 81012 Federal Register / Vol. 89, No. 194 / Monday, October 7, 2024 / Rules and Regulations There are no acute and chronic residential exposure scenarios; therefore, the acute and chronic aggregate risks are equivalent to the acute and chronic dietary (food and drinking water) risk estimates and are not of concern. For risk conclusions specific to flazasulfuron in/on avocado, refer to Unit III section for acute and chronic dietary risk assessments within this document. Flazasulfuron is currently registered for a use that could result in short-term residential exposure, and the Agency has determined that it is appropriate to aggregate chronic exposure through food and water with short-term residential exposures to flazasulfuron. Using the exposure assumptions described in this unit for short-term exposures, EPA has concluded the combined short-term food, water, and residential exposures result in aggregate MOEs of 1660 for adults and 860 for children. Because EPA’s level of concern for flazasulfuron is a MOE of 100 or greater, these MOEs are not of concern. Further, no intermediate-term adverse effect was identified, as a result, intermediate-term risk is not expected. Aggregate cancer risk for U.S. population. A cancer aggregate risk assessment was not conducted because there was no evidence of carcinogenicity to humans based on lack of carcinogenic effects in the rat and mouse carcinogenicity studies. Flazasulfuron was classified as ‘‘not likely to be carcinogenic to humans;’’ therefore, a cancer dietary assessment was not performed. Determination of safety. Based on these risk assessments, 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 flazasulfuron residues. IV. Other Considerations A. Analytical Enforcement Methodology lotter on DSK11XQN23PROD with RULES1 An adequate enforcement method for flazasulfuron is available. The method uses high-performance liquid chromatography/tandem mass spectrometry with multiple reaction monitoring (HPLC/MS–MS/MRM). The validated limit of quantitation (LOQ) is 0.01 ppm. 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 VerDate Sep<11>2014 15:55 Oct 04, 2024 Jkt 262001 international maximum residue limits (MRLs) established by the Codex Alimentarius Commission (Codex), as required by FFDCA section 408(b)(4). The Codex Alimentarius is a joint United Nations 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 flazasulfuron. There are currently no MRLs established by Codex or Canada; therefore, there are no issues regarding international harmonization to date. C. Response to Comments One comment was received in favor of this action from the United States Department of Agriculture (USDA). Given the potential herbicide resistance management value for flazasulfuron in avocado, USDA strongly supports the application for registration of flazasulfuron in avocado. V. Conclusion Therefore, a tolerance is established for residues of flazasulfuron, 1-(4,6dimethoxypyrimidin-2-yl)-3-(3trifluoromethyl-2-pyridylsulfonyl)urea, in or on Avocado at 0.01 ppm. VI. Statutory and Executive Order Reviews This action establishes tolerances under FFDCA section 408(d) 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 action has been exempted from review under Executive Order 12866, this action 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 action 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 PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 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 FFDCA section 408(d), 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 action 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 FFDCA section 408(n)(4). 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 action. In addition, this action does not impose any enforceable duty or contain any unfunded mandate as described under title II of the Unfunded Mandates Reform Act (UMRA) (2 U.S.C. 1501 et seq.). 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 (NTTAA) (15 U.S.C. 272 note). VII. Congressional Review Act Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 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 the rule in the Federal Register. This action is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2).

II. Summary of Petitioned-For Tolerance

    In the Federal Register of September 20, 2023 (88 FR 64909) (FRL-
10578-08-OCSPP), EPA issued a document pursuant to FFDCA section 
408(d)(3), 21 U.S.C. 346a(d)(3), announcing the filing of a pesticide 
petition (PP 3F9055) by ISK Biosciences Corporation, 7470 Auburn Road, 
Suite A, Concord, OH 44077. The petition requested that 40 CFR 180.655 
be amended by a establishing tolerance for residues of the herbicide 
Flazasulfuron, 1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-trifluoromethyl-2-
pyridylsulfonyl)urea, in or on Avocado at 0.01 parts per

[[Page 81011]]

million (ppm). That document referenced a summary of the petition 
prepared by ISK Biosciences Corporation, the registrant, which is 
available in the docket, https://www.regulations.gov. One comment was 
received on the notice of filing. EPA's response to this comment 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 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 FFDCA section 408(b)(2)(D), and the factors 
specified in FFDCA section 408(b)(2)(D), 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 flazasulfuron including 
exposure resulting from the tolerances established by this action. 
EPA's assessment of exposures and risks associated with flazasulfuron 
follows.
    In an effort to streamline its publications in the Federal 
Register, EPA is not reprinting sections that repeat what has been 
previously published for tolerance rulemakings of the same pesticide 
chemical. Where scientific information concerning a particular chemical 
remains unchanged, the content of those sections would not vary between 
tolerance rulemakings, and republishing the same sections are 
unnecessary. EPA considers referral back to those sections as 
sufficient to provide an explanation of the information EPA considered 
in making its safety determination for the new rulemaking.
    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. Specific information on the studies received and the nature 
of the toxic effects caused by flazasulfuron as well as the no-
observed-adverse-effect-level (NOAEL) and the lowest-observed-adverse-
effect-level (LOAEL) from the toxicity studies can be found in Unit 
II.A, of the May 25, 2017, rulemaking.
    There are no changes to the prior endpoint selections from the 2015 
Draft Risk Assessment for Registration Review. In that risk assessment 
some studies used for endpoint selection were judged to have 
conservative NOAEL/LOAEL values because they were not updated to 
reflect current standards for evaluating toxicity studies. Such updates 
would likely result in higher NOAEL/LOAEL values and given the current 
risk picture, would not impact the overall findings of this risk 
assessment. Therefore, these studies were not re-evaluated in 
conjunction with this risk assessment. A detailed description of 
endpoint selection can be found at https://www.regulations.gov, 
``Flazasulfuron: Human Health Draft Risk Assessment for Registration 
Review, dated September 15, 2015.
    The acute and chronic dietary risk assessments for flazasulfuron 
are unrefined assessments which incorporate tolerance-level residues, 
100% crop treated (CT), and modeled estimated drinking water 
concentrations (EDWCs). The processing factors were set to 1 for the 
processed commodities that are in table 1 (860.1000). A default 
processing factor was used for hazelnut. The results of acute dietary 
(food and drinking water) analysis are below the Agency's level of 
concern (LOC) for all population subgroups. The acute dietary risk 
estimates utilized <1.0% of the acute population-adjusted dose (aPAD) 
for the general U.S. population and 3.3% of the aPAD for infants (<1 
years old), the most highly exposed population subgroup. The results of 
chronic dietary (food and drinking water) analysis are below the 
Agency's LOC for all population subgroups. The chronic dietary risk 
estimates utilized 8.8% of the chronic population-adjusted dose (cPAD) 
for the general U.S. population and 32% of the cPAD for infants (<1 
years old), the most highly exposed population subgroup. Based on the 
data summarized in Unit III.A. of the May 25, 2017, rulemaking, EPA has 
concluded that flazasulfuron does not pose a cancer risk to humans. 
Therefore, a dietary exposure assessment for the purpose of assessing 
cancer risk is unnecessary.
    EDWCs from the previous drinking water assessment are considered 
protective of the new use and may be used to represent EDWCs for the 
proposed new use on avocados. EDWCs include total toxic residues of 
flazasulfuron (i.e., all of the degradates: DTPU, DTPP, HTPP, TPSA, 
ADMP, and 2,3-GTF). The highest EDWCs from the previous assessment were 
from ground water and were modeled using Pesticide Root Zone Model for 
Ground Water (PRZM-GW). EPA's conclusions remain unchanged from Unit 
II. C.2 of the May 25, 2017, rulemaking.
    There is no residential exposure associated with the proposed use 
in this action; however, there is residential exposure from an existing 
registered use on turf that has been previously assessed using current 
data and assumptions for flazasulfuron. Risk estimates have been 
presented for the purpose of aggregate assessment; and conclude all 
residential risk estimates are not of concern. For more details, see 
Unit II.C.3 of the May 25, 2017, rulemaking. Further information 
regarding EPA standard assumptions and generic inputs for residential 
exposures may be found at https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/standard-operating-procedures-residential-pesticide.
    No further data are required to determine that no common mechanism 
of toxicity exists for flazasulfuron and other pesticides. As a result, 
no further cumulative evaluation is necessary for flazasulfuron as 
published in Unit II.C.4 of the May 25, 2017, rulemaking.
    The toxicity database for flazasulfuron is complete and adequate to 
assess susceptibility in the young. While there is evidence of 
increased qualitative and quantitative susceptibility in the young 
based on rat malformations and decreased fetal weight in two rat 
developmental toxicity studies, the Food Quality Protection Act (FQPA) 
Safety Factor (SF) is reduced to 1X and is protective of the observed 
offspring susceptibility because: (1) there are clear NOAELs for the 
developmental effects in the two rat studies developmental toxicity 
studies and the PODs selected for risk assessment are protective of 
those effects, (2) there is no evidence of neurotoxicity, and (3) 
exposure estimates are unlikely to underestimate risk. These 
conclusions are further discussed in Unit II.D of the May 25, 2017, 
rulemaking.

[[Page 81012]]

    There are no acute and chronic residential exposure scenarios; 
therefore, the acute and chronic aggregate risks are equivalent to the 
acute and chronic dietary (food and drinking water) risk estimates and 
are not of concern. For risk conclusions specific to flazasulfuron in/
on avocado, refer to Unit III section for acute and chronic dietary 
risk assessments within this document.
    Flazasulfuron is currently registered for a use that could result 
in short-term residential exposure, and the Agency has determined that 
it is appropriate to aggregate chronic exposure through food and water 
with short-term residential exposures to flazasulfuron.
    Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water, 
and residential exposures result in aggregate MOEs of 1660 for adults 
and 860 for children. Because EPA's level of concern for flazasulfuron 
is a MOE of 100 or greater, these MOEs are not of concern.
    Further, no intermediate-term adverse effect was identified, as a 
result, intermediate-term risk is not expected.
    Aggregate cancer risk for U.S. population. A cancer aggregate risk 
assessment was not conducted because there was no evidence of 
carcinogenicity to humans based on lack of carcinogenic effects in the 
rat and mouse carcinogenicity studies. Flazasulfuron was classified as 
``not likely to be carcinogenic to humans;'' therefore, a cancer 
dietary assessment was not performed.
    Determination of safety. Based on these risk assessments, 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 flazasulfuron residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    An adequate enforcement method for flazasulfuron is available. The 
method uses high-performance liquid chromatography/tandem mass 
spectrometry with multiple reaction monitoring (HPLC/MS-MS/MRM). The 
validated limit of quantitation (LOQ) is 0.01 ppm.

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 (MRLs) established 
by the Codex Alimentarius Commission (Codex), as required by FFDCA 
section 408(b)(4). The Codex Alimentarius is a joint United Nations 
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 flazasulfuron. There are 
currently no MRLs established by Codex or Canada; therefore, there are 
no issues regarding international harmonization to date.

C. Response to Comments

    One comment was received in favor of this action from the United 
States Department of Agriculture (USDA). Given the potential herbicide 
resistance management value for flazasulfuron in avocado, USDA strongly 
supports the application for registration of flazasulfuron in avocado.

V. Conclusion

    Therefore, a tolerance is established for residues of 
flazasulfuron, 1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-trifluoromethyl-2-
pyridylsulfonyl)urea, in or on Avocado at 0.01 ppm.

VI. Statutory and Executive Order Reviews

    This action establishes tolerances under FFDCA section 408(d) 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 action has been 
exempted from review under Executive Order 12866, this action 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 action 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 FFDCA section 408(d), 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 action 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 FFDCA section 408(n)(4). 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 action. In addition, 
this action does not impose any enforceable duty or contain any 
unfunded mandate as described under title II of the Unfunded Mandates 
Reform Act (UMRA) (2 U.S.C. 1501 et seq.).
    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 (NTTAA) (15 U.S.C. 272 note).

VII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
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 
the rule in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).
