Summary of Petitioned-For Tolerance In the Federal Register of August 24, 2021 86 FR 47275 (FRL–8792–02– 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 0F8875) by Corteva Agrosciences, 9330 Zionsville Rd., Indianapolis, IN 46268. The petition requested that 40 CFR 180.350 be amended by establishing a tolerance for combined residues or residues of the nitrification inhibitor nitrapyrin and its metabolite, 6-chloropicolinic acid (6– CPA), in or on cottonseed crop subgroup 20C; cotton, gin byproducts; cotton, meal; rice, grain; and rice, straw at 4.0, 0.6, 6.0, 0.03 and 0.15 parts per million (ppm), respectively. That document referenced a summary of the petition prepared by Corteva Agrosciences, the registrant, which is included in the docket. There were no comments received in response to the notice of filing. 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 a tolerance for combined residues or residues of nitrapyrin and its metabolite, 6chloropicolinic acid (6–CPA), in or on VerDate Sep<11>2014 16:18 Jan 21, 2022 Jkt 256001 cottonseed crop subgroup 20C; cotton, gin byproducts; cotton, meal; rice, grain; and rice, straw at 4.0, 0.6, 6.0, 0.03 and 0.15 parts per million (ppm), respectively. EPA’s assessment of exposures and risks associated with establishing the tolerance 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 rulemaking of the same pesticide chemical. Where scientific information concerning a particular chemical remains unchanged, the content of those sections would not vary between tolerance rulemaking and republishing the same sections is 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 previously published a number of tolerance rulemakings for nitrapyrin, in which EPA concluded, based on the available information, that there is a reasonable certainty that no harm would result from aggregate exposure to nitrapyrin and established tolerances for residues of that chemical. EPA is incorporating previously published sections from those rulemakings as described further in this rulemaking, as they remain unchanged. On August 27, 2019, EPA published in the Federal Register a final rule establishing tolerances for residues of nitrapyrin in or on sugar beet molasses, sugar beet roots, sugar beet tops, rapeseed seed, and the vegetable, tuberous and corm, crop subgroup 1C. See (85 FR 48651) (FRL–10009–42). That document contains a summary of the toxicological profile, assumptions for dietary exposure assessment, cumulative risk, and the safety factor for children, which have not changed. More detailed information on the subject action to establish a tolerance in or on cotton and rice can be found in the document titled, ‘‘Nitrapyrin. Human Health Risk Assessment for New Uses in/on Cotton and Rice,’’ dated December 8, 2021 by going to https:// www.regulations.gov. The referenced document is available in the docket EPA–HQ–OPP–2021–0352. Toxicological profile. For a discussion of the Toxicological Profile of nitrapyrin, see Unit III of the August 12, 2020 rulemaking (85 FR 48651) (FRL– 10009–42). There have been no changes to the toxicological endpoints since the last risk assessment. Toxicological points of departure/ Levels of concern. For a summary of the Toxicological Points of Departure/ PO 00000 Frm 00027 Fmt 4700 Sfmt 4700 3447 Levels of Concern for nitrapyrin, see the document titled: ‘‘Nitrapyrin. Human Health Risk Assessment for New Uses in/on Cotton and Rice,’’ dated December 8, 2021, in docket number EPA–HQ– OPP–2021–0352. Exposure assessment. EPA’s dietary exposure assessments have been updated to include the additional exposure from the new uses of nitrapyrin on cotton and rice. The assessment used the same assumptions as the August 12, 2020 final rule concerning tolerance-level residues, default processing factors for all processed commodities, and 100 percent crop treated. Drinking water exposure. EPA has revised the nitrapyrin drinking water assessment since the August 12, 2020 final rule. Surface water and groundwater modeling were simulated using the Pesticide in Water Calculator (PWC version 2.0; Sep. 18, 2020) for use on cotton. The Pesticides in Flooded Applications Model (PFAM; version 2.0; Sep. 27, 2016) was also used in surface water modeling for use on rice. The highest estimated drinking water concentrations (EDWCs) are 124 mg/L for acute exposure and 111 mg/L for chronic exposure from ground water sources based on the Florida (FL) central ridge model scenarios. Non-occupational exposure. There are no currently registered or proposed residential uses for nitrapyrin; therefore, residential handler and post-application exposure and risks were not assessed. Cumulative exposures. 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 nitrapyrin and any other substances and nitrapyrin does not appear to produce a toxic metabolite produced by other substances. For the purposes of this action, therefore, EPA has not assumed that nitrapyrin has a common mechanism of toxicity with other substances. Safety factor for infants and children. EPA continues to conclude that there are reliable data to support the reduction of the Food Quality Protection Act (FQPA) safety factor. See Unit III of the August 12, 2020 final rule for a discussion of the Agency’s rationale for that determination. Aggregate risk and determination of safety. EPA determines whether acute and chronic dietary pesticide exposures are safe by comparing aggregate exposure estimates to the acute population adjusted dose (aPAD) and the chronic population adjusted dose (cPAD). Short-, intermediate-, and chronic term risks are evaluated by E:\FR\FM\24JAR1.SGM 24JAR1 3448 Federal Register / Vol. 87, No. 15 / Monday, January 24, 2022 / Rules and Regulations comparing the estimated aggregate food, water, and residential exposure to the appropriate points of departure to ensure that an adequate margin of exposure (MOE) exists. For linear cancer risks, EPA calculates the lifetime probability of acquiring cancer given the estimated aggregate exposure. The acute dietary (food and water) risk estimates are below EPA’s level of concern for all population subgroups (<100% of the acute population adjusted dose (aPAD)). The population subgroup with the highest acute risk estimate is all-infants (<1 year-old), at 14% of the aPAD. The chronic dietary (food and water) risk estimates are below HED’s level of concern for all population subgroups (<100% of the chronic adjusted population dose (cPAD)). The population subgroup with the highest chronic risk estimate is children (1 to 2 years old) at 26% of the cPAD. Since there are no registered residential uses, the acute and chronic aggregate exposure and risk assessment are equivalent to the dietary (food and drinking water) exposure and risk estimates and are below EPA’s level of concern (<26% of the cPAD). Nitrapyrin is classified as ‘‘not likely to be carcinogenic to humans at doses that do not result in constitutive androstane receptor (CAR) activation as indicated by Cyp2b10 expression’’. Therefore, the chronic dietary endpoint and assessment are protective of all chronic risks, including potential carcinogenic effects. More detailed information can be found at https://www.regulations.gov in the document titled ‘‘Nitrapyrin. Human Health Risk Assessment for the Section 3 Registration Action for New Uses on in/on Cotton and Rice,’’ dated December 8, 2021 by going to https:// www.regulations.gov. The referenced document is available in the docket EPA–HQ–OPP–2021–0352. IV. Other Considerations A. Analytical Enforcement Methodology jspears on DSK121TN23PROD with RULES1 Adequate enforcement methodology (gas chromatography with electron capture detection) is available to enforce the tolerance expression. Seven analytical methods are available in Volume II of the Pesticide Analytical Manual (PAM II—Pesticide Reg. Sec. 180.350) for tolerance enforcement for nitrapyrin and/or for metabolite 6–CPA. B. International Residue Limits Codex and Canada have not established maximum residue limits (MRLs) for residues of nitrapyrin. Therefore, there are no issues related to international harmonization. A VerDate Sep<11>2014 16:18 Jan 21, 2022 Jkt 256001 summary of the MRLs can be found in Appendix D of the document titled ‘‘Nitrapyrin. Human Health Risk Assessment for the Section 3 Registration Action for New Uses on in/ on Cotton and Rice,’’ dated December 8, 2021 by going to https:// www.regulations.gov. The referenced document is available in the docket EPA–HQ–OPP–2021–0352. C. Revisions to Petitioned-For Tolerances Rice straw is no longer considered a significant livestock feed item and a tolerance is therefore unnecessary. Additionally, tolerance values for cottonseed crop subgroup 20C, cotton, gin byproducts and cotton meal are being established consistent with the Agency’s rounding class practice. V. Conclusion Therefore, tolerances are established for the residues of nitrapyrin in or on cottonseed crop subgroup 20C at 4 parts per million (ppm); cotton, gin byproducts at 0.6 ppm; cotton, meal at 6 ppm; and rice, grain at 0.03 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 tolerances in this final rule, do not require the issuance of a proposed rule, the requirements of the Regulatory PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 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 August 24, 2021 86 FR 47275 (FRL-8792-
02-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 
0F8875) by Corteva Agrosciences, 9330 Zionsville Rd., Indianapolis, IN 
46268. The petition requested that 40 CFR 180.350 be amended by 
establishing a tolerance for combined residues or residues of the 
nitrification inhibitor nitrapyrin and its metabolite, 6-
chloropicolinic acid (6-CPA), in or on cottonseed crop subgroup 20C; 
cotton, gin byproducts; cotton, meal; rice, grain; and rice, straw at 
4.0, 0.6, 6.0, 0.03 and 0.15 parts per million (ppm), respectively. 
That document referenced a summary of the petition prepared by Corteva 
Agrosciences, the registrant, which is included in the docket. There 
were no comments received in response to the notice of filing.

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 a tolerance for combined 
residues or residues of nitrapyrin and its metabolite, 6-
chloropicolinic acid (6-CPA), in or on cottonseed crop subgroup 20C; 
cotton, gin byproducts; cotton, meal; rice, grain; and rice, straw at 
4.0, 0.6, 6.0, 0.03 and 0.15 parts per million (ppm), respectively. 
EPA's assessment of exposures and risks associated with establishing 
the tolerance 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 rulemaking of the same pesticide 
chemical. Where scientific information concerning a particular chemical 
remains unchanged, the content of those sections would not vary between 
tolerance rulemaking and republishing the same sections is 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 previously published a number of tolerance rulemakings for 
nitrapyrin, in which EPA concluded, based on the available information, 
that there is a reasonable certainty that no harm would result from 
aggregate exposure to nitrapyrin and established tolerances for 
residues of that chemical. EPA is incorporating previously published 
sections from those rulemakings as described further in this 
rulemaking, as they remain unchanged. On August 27, 2019, EPA published 
in the Federal Register a final rule establishing tolerances for 
residues of nitrapyrin in or on sugar beet molasses, sugar beet roots, 
sugar beet tops, rapeseed seed, and the vegetable, tuberous and corm, 
crop subgroup 1C. See (85 FR 48651) (FRL-10009-42). That document 
contains a summary of the toxicological profile, assumptions for 
dietary exposure assessment, cumulative risk, and the safety factor for 
children, which have not changed. More detailed information on the 
subject action to establish a tolerance in or on cotton and rice can be 
found in the document titled, ``Nitrapyrin. Human Health Risk 
Assessment for New Uses in/on Cotton and Rice,'' dated December 8, 2021 
by going to https://www.regulations.gov. The referenced document is 
available in the docket EPA-HQ-OPP-2021-0352.
    Toxicological profile. For a discussion of the Toxicological 
Profile of nitrapyrin, see Unit III of the August 12, 2020 rulemaking 
(85 FR 48651) (FRL-10009-42). There have been no changes to the 
toxicological endpoints since the last risk assessment.
    Toxicological points of departure/Levels of concern. For a summary 
of the Toxicological Points of Departure/Levels of Concern for 
nitrapyrin, see the document titled: ``Nitrapyrin. Human Health Risk 
Assessment for New Uses in/on Cotton and Rice,'' dated December 8, 
2021, in docket number EPA-HQ-OPP-2021-0352.
    Exposure assessment. EPA's dietary exposure assessments have been 
updated to include the additional exposure from the new uses of 
nitrapyrin on cotton and rice. The assessment used the same assumptions 
as the August 12, 2020 final rule concerning tolerance-level residues, 
default processing factors for all processed commodities, and 100 
percent crop treated.
    Drinking water exposure. EPA has revised the nitrapyrin drinking 
water assessment since the August 12, 2020 final rule. Surface water 
and groundwater modeling were simulated using the Pesticide in Water 
Calculator (PWC version 2.0; Sep. 18, 2020) for use on cotton. The 
Pesticides in Flooded Applications Model (PFAM; version 2.0; Sep. 27, 
2016) was also used in surface water modeling for use on rice. The 
highest estimated drinking water concentrations (EDWCs) are 124 [mu]g/L 
for acute exposure and 111 [micro]g/L for chronic exposure from ground 
water sources based on the Florida (FL) central ridge model scenarios.
    Non-occupational exposure. There are no currently registered or 
proposed residential uses for nitrapyrin; therefore, residential 
handler and post-application exposure and risks were not assessed.
    Cumulative exposures. 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 
nitrapyrin and any other substances and nitrapyrin does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this action, therefore, EPA has not assumed that nitrapyrin 
has a common mechanism of toxicity with other substances.
    Safety factor for infants and children. EPA continues to conclude 
that there are reliable data to support the reduction of the Food 
Quality Protection Act (FQPA) safety factor. See Unit III of the August 
12, 2020 final rule for a discussion of the Agency's rationale for that 
determination.
    Aggregate risk and determination of safety. EPA determines whether 
acute and chronic dietary pesticide exposures are safe by comparing 
aggregate exposure estimates to the acute population adjusted dose 
(aPAD) and the chronic population adjusted dose (cPAD). Short-, 
intermediate-, and chronic term risks are evaluated by

[[Page 3448]]

comparing the estimated aggregate food, water, and residential exposure 
to the appropriate points of departure to ensure that an adequate 
margin of exposure (MOE) exists. For linear cancer risks, EPA 
calculates the lifetime probability of acquiring cancer given the 
estimated aggregate exposure.
    The acute dietary (food and water) risk estimates are below EPA's 
level of concern for all population subgroups (<100% of the acute 
population adjusted dose (aPAD)). The population subgroup with the 
highest acute risk estimate is all-infants (<1 year-old), at 14% of the 
aPAD. The chronic dietary (food and water) risk estimates are below 
HED's level of concern for all population subgroups (<100% of the 
chronic adjusted population dose (cPAD)). The population subgroup with 
the highest chronic risk estimate is children (1 to 2 years old) at 26% 
of the cPAD.
    Since there are no registered residential uses, the acute and 
chronic aggregate exposure and risk assessment are equivalent to the 
dietary (food and drinking water) exposure and risk estimates and are 
below EPA's level of concern (<26% of the cPAD). Nitrapyrin is 
classified as ``not likely to be carcinogenic to humans at doses that 
do not result in constitutive androstane receptor (CAR) activation as 
indicated by Cyp2b10 expression''. Therefore, the chronic dietary 
endpoint and assessment are protective of all chronic risks, including 
potential carcinogenic effects. More detailed information can be found 
at https://www.regulations.gov in the document titled ``Nitrapyrin. 
Human Health Risk Assessment for the Section 3 Registration Action for 
New Uses on in/on Cotton and Rice,'' dated December 8, 2021 by going to 
https://www.regulations.gov. The referenced document is available in 
the docket EPA-HQ-OPP-2021-0352.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (gas chromatography with electron 
capture detection) is available to enforce the tolerance expression. 
Seven analytical methods are available in Volume II of the Pesticide 
Analytical Manual (PAM II--Pesticide Reg. Sec. 180.350) for tolerance 
enforcement for nitrapyrin and/or for metabolite 6-CPA.

B. International Residue Limits

    Codex and Canada have not established maximum residue limits (MRLs) 
for residues of nitrapyrin. Therefore, there are no issues related to 
international harmonization. A summary of the MRLs can be found in 
Appendix D of the document titled ``Nitrapyrin. Human Health Risk 
Assessment for the Section 3 Registration Action for New Uses on in/on 
Cotton and Rice,'' dated December 8, 2021 by going to https://www.regulations.gov. The referenced document is available in the docket 
EPA-HQ-OPP-2021-0352.

C. Revisions to Petitioned-For Tolerances

    Rice straw is no longer considered a significant livestock feed 
item and a tolerance is therefore unnecessary. Additionally, tolerance 
values for cottonseed crop subgroup 20C, cotton, gin byproducts and 
cotton meal are being established consistent with the Agency's rounding 
class practice.

V. Conclusion

    Therefore, tolerances are established for the residues of 
nitrapyrin in or on cottonseed crop subgroup 20C at 4 parts per million 
(ppm); cotton, gin byproducts at 0.6 ppm; cotton, meal at 6 ppm; and 
rice, grain at 0.03 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 tolerances 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).
