II. Summary of Petitioned-For Tolerance

    In the Federal Register of October 23, 2017 (82 FR 49020) (FRL-
9967-37), 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 
7E8549) by IR-4, Rutgers, The State University of New Jersey, 500 
College Road East, Suite 201 W, Princeton, NJ 08540. The petition 
requested that 40 CFR part 180 be amended by establishing tolerances 
for residues of the herbicide florasulam N-(2,6-difluorophenyl)-8-
fluoro-5-methoxy (1,2,4)triazolo(1,5-c)pyrimidine-2-sulfonamide in or 
on the raw agricultural commodities teff, forage at 0.05 parts per 
million (ppm); teff, grain at 0.01 ppm; teff, straw at 0.05 ppm; and 
teff, hay at 0.05 ppm. That document referenced a summary of the 
petition prepared by Dow AgroSciences, the registrant, which is 
available in the docket, http://www.regulations.gov. A 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 florasulam including exposure 
resulting from the tolerances established by this action. EPA's 
assessment of exposures and risks associated with florasulam 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.
    There was slight nephrotoxicity (increased kidney weights, 
hypertrophy, and degeneration/regeneration and inflammation of the 
descending portion of proximal tubules) observed in the kidneys of rats 
(both sexes) after subchronic exposure to florasulam (90 days) at or 
greater than 500 milligrams/kilogram/day (mg/kg/day). Chronic exposure 
in rats led to slight nephrotoxicity (increased kidney weights, 
hypertrophy, and slight multi-focal mineralization of the papilla) at 
250 and 500 mg/kg/day in males only. Additionally, at 500 mg/kg/day, 
papillary necrosis and hyperplasia of the transitional epithelium 
(papilla) were observed in the kidney (males). Decreases in body weight 
and body weight gain were also observed in females after subchronic 
(500 mg/kg/day) and chronic exposure (250 mg/kg/day). Liver toxicity 
was observed in dogs (both sexes) in the form of increased alkaline 
phosphatase activity (59-127%), increased liver weights, hypertrophy, 
and hepatic vacuolation at 50 mg/kg/day after 90 days. After 1 year, 
there were increases in alkaline phosphatase (233-783%) in dogs (both 
sexes) but no changes in liver weights or gross or microscopic 
pathology at 50 mg/kg/day. Additionally, there were decreases in body 
weight, body weight gain and food consumption, as well as vacuolation 
of the zona reticularis and zona fasciculate in the adrenal gland 
(consistent with fatty change) in both sexes. There were no adverse 
effects noted after subchronic/chronic exposure to florasulam in mice 
up to the limit dose of 1,000 mg/kg/day.
    There was no evidence of developmental toxicity or indications of

[[Page 35143]]

neonatal sensitivity in the developmental and reproduction toxicity 
studies (rats and rabbits). In the rat developmental toxicity study, 
decreased body weights and decreased food consumption were observed. 
There were also slight decreases observed in fetal body weight and 
delays in ossification observed in fetuses at the high dose. However, 
the minor differences were not considered adverse since there was no 
clear dose-response relationship and the values (both findings) fell 
within historical control values. Furthermore, the findings were 
attributed to the associated decreases in maternal body weights. There 
were no treatment-related effects observed in dams or offspring in the 
developmental toxicity study in rabbits. In the reproduction toxicity 
study in rats, there were decreased body weights, body weight gains, 
and food consumption, as well as increased kidney weights and 
hypertrophy in both sexes at 500 mg/kg/day. Additionally, at 500 mg/kg/
day, transient decreases in pup body weights were observed on post-
natal day 4 pre-culling (F1 and F2 males) and post-natal day 7 (F1 
females and F2 males and females); however, by post-natal day 21, all 
treated groups were similar to controls. The decreases observed were 
associated with decreased maternal body weight and food consumption and 
were transient in nature; thus, they were not considered adverse.
    Dermal exposure to florasulam did not result in systemic toxicity 
up to the limit dose of 1,000 mg/kg/day. There is no evidence of 
neurotoxicity, mutagenicity, or carcinogenicity after exposure to 
florasulam. In addition, there is no evidence of endocrine related 
toxicity.
    Specific information on the studies received and the nature of the 
adverse effects caused by florasulam 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 at http://www.regulations.gov in the document titled ``Florasulam: Human Health 
Risk Assessment for proposed use on Turfgrass'' (``2009 Florasulam 
Turfgrass Assessment'') on pages 35-39 in docket ID number EPA-HQ-OPP-
2017-0226. The Agency is relying on this risk assessment because the 
toxicological profile for florasulam has not changed since that risk 
assessment was conducted and as indicated in a more recent assessment 
for use on teff, the Agency has concluded that registering use on teff 
would not alter the Agency's previously assessed exposure estimates for 
florasulam. See ``Florasulam: Human Health Risk Assessment for Proposed 
Use on Teff'' (Dec. 6, 2017) (``2017 Florasulam Teff Assessment''), 
which can also be found in http://www.regulations.gov in docket ID 
number EPA-HQ-OPP-2017-0226.

B. Toxicological Points of Departure/Levels of Concern

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological points of departure (POD) and levels of 
concern to use in evaluating the risk posed by human exposure to the 
pesticide. For hazards that have a threshold below which there is no 
appreciable risk, the toxicological POD is used as the basis for 
derivation of reference values for risk assessment. PODs are developed 
based on a careful analysis of the doses in each toxicological study to 
determine the dose at which no adverse effects are observed (the NOAEL) 
and the lowest dose at which adverse effects of concern are identified 
(the LOAEL). Uncertainty/safety factors are used in conjunction with 
the POD to calculate a safe exposure level--generally referred to as a 
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe 
margin of exposure (MOE). For non-threshold risks, the Agency assumes 
that any amount of exposure will lead to some degree of risk. Thus, the 
Agency estimates risk in terms of the probability of an occurrence of 
the adverse effect expected in a lifetime. For more information on the 
general principles EPA uses in risk characterization and a complete 
description of the risk assessment process, see http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/assessing-human-health-risk-pesticides.
    A summary of the toxicological endpoints for florasulam used for 
human risk assessment is shown in Table 1 of this unit.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. EPA's most recent 
quantitative dietary assessment was conducted in connection with the 
registration of turfgrass uses for florasulam. See 2009 Florasulam 
Turfgrass Assessment. That document considered dietary exposure for 
residues of florasulam in food associated with the all existing 
florasulam tolerances in 40 CFR 180.633 as described in Unit III.C.1. 
of the 2007 rulemaking establishing those tolerances. 72 FR 55073 
(Sept. 28, 2007). EPA has determined that approval of the use on teff 
will not change those dietary exposure estimates for residues of 
florasulam in or on food. The Agency expects residues on teff to be 
similar to those residues in or on wheat because of the similarity in 
use pattern and application rates. Teff is prepared like other whole 
grains, such as rice and barley, and may also be used to make flour in 
a manner similar to wheat and other cereal grains. As a flour, the 
Agency expects that teff will likely substitute in the diet for cereal 
grain foods rather than add to dietary exposure. With respect to 
livestock commodities, residues of florasulam in teff livestock feeds 
are expected to be similar to those in other forages, hays, and silages 
for which florasulam is currently registered. Therefore, there would be 
no increase in the livestock dietary burden should teff be substituted 
in the livestock diet for other hays and silages; residues in meat, 
milk, poultry and eggs will remain the same.
    2. Dietary exposure from drinking water. In the 2009 Florasulam 
Turfgrass Assessment, the Agency used screening-level water exposure 
models in the dietary exposure analysis and risk assessment for 
florasulam in drinking water. These simulation models take into account 
data on the physical, chemical, and fate/transport characteristics of 
florasulam. Further information regarding EPA drinking water models 
used in pesticide exposure assessment can be found at http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/about-water-exposure-models-used-pesticide.
    To arrive at the total EDWC (estimated drinking water 
concentrations), the maximum surface water and ground water values for 
the parent was added to the maximum surface water and ground water 
value for the major degradate. Based on the FQPA Index Reservoir 
Screening Tool (FIRST), and Screening Concentration in Ground Water 
(SCI-GROW) models, the estimated drinking water concentrations (EDWCs) 
of florasulam use on turfgrass for chronic exposures are estimated to 
be 1.36 parts per billion (ppb) for surface water and 0.06 ppb for 
ground water.
    The Agency has concluded that the teff use will not increase 
drinking water exposure estimates because the teff use pattern is 
similar to the use patterns on wheat and barley. The wheat and barley 
use patterns yield EDWCs that are approximately nine times lower than 
the use on turfgrass and thus would not be used to assess dietary 
exposure. Therefore, the Agency used the same modeled estimates of 
drinking water concentrations from the 2009 Florasulam Turfgrass 
Assessment: For the chronic dietary risk assessment, the water 
concentration of value 1.36 ppb was used to assess the contribution to 
drinking 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).
    Florasulam is currently registered for the following uses that 
could result in residential exposures: Turf. The new use on teff is not 
a residential use. Therefore, EPA is relying on its 2009 Florasulam 
Turfgrass Assessment to assess residential exposures. EPA assessed 
residential exposure using the following assumptions: Short-term 
inhalation exposure is expected to handlers as a result of applying 
florasulam to turf. There is no short-term dermal endpoint for 
florasulam, and therefore, no dermal risks were assessed for 
residential handlers. The scenarios assessed for handlers was mixing/
loading/applying florasulam to turf with various application equipment.
    For post-application, the Agency determined there is a potential 
for exposure from entering florasulam-treated residential areas, such 
as lawns, sports fields, and golf courses that could lead to post-
application exposures to adults and children. No short-term dermal 
point of departure was identified for florasulam. Therefore, no dermal 
risks were assessed for residential post-application exposures.
    The Agency assumed that inhalation exposures are minimal following 
outdoor applications of an active ingredient with low vapor pressure. 
Since the proposed use of florasulam include only outdoor applications 
and florasulam has a low vapor pressure, post-application inhalation 
exposures and risks were not assessed. The scenario resulting in the 
highest exposure was short-term incidental oral risks for toddlers 
after applications of florasulam to lawns. The exposure scenarios 
include hand to mouth, object to mouth, incidental soil ingestion and 
the combination of all three of these scenarios.
    Further information regarding EPA standard assumptions and generic 
inputs for residential exposures may be found at http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/standard-operating-procedures-residential-pesticide.
    4. Cumulative effects from substances with a common mechanism of 
toxicity. Section 408(b)(2)(D)(v) of 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 pesticide's residues and ``other

[[Page 35145]]

substances that have a common mechanism of toxicity.''
    EPA has not found florasulam to share a common mechanism of 
toxicity with any other substances, and florasulam does not appear to 
produce a toxic metabolite produced by other substances. For the 
purposes of this tolerance action, therefore, EPA has assumed that 
florasulam does not have 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 EPA's website at http://www2.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.

D. Safety Factor for Infants and Children

    1. In general. Section 408(b)(2)(C) of FFDCA provides that EPA 
shall apply an additional tenfold (10X) 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 database on toxicity 
and exposure unless EPA determines based on reliable data that a 
different margin of safety will be safe for infants and children. This 
additional margin of safety is commonly referred to as the Food Quality 
Protection Act Safety Factor (FQPA SF). In applying this provision, EPA 
either retains the default value of 10X, or uses a different additional 
safety factor when reliable data available to EPA support the choice of 
a different factor.
    2. Prenatal and postnatal sensitivity. There was no evidence of 
developmental toxicity or indications of neonatal sensitivity in the 
developmental and reproduction toxicity studies (rats and rabbits). In 
the rat developmental toxicity study (750 mg/kg/day) body weights were 
decreased by 4-6% during gestation days 6-19, resulting in a 16% 
decrease in body weight gains during treatment (gestation days 6-16); 
food consumption was also decreased (not statistically analyzed) by 6-
13% during the treatment period. Additionally, at this dose, absolute 
and relative (to body weight) kidney weights were increased (p<= 0.05) 
by 8 and 12%, respectively. At 250 and 750 mg/kg/day, slight decreases 
(3-4%) were observed in fetal body weight. Additionally, there were 
delays in ossification observed in fetuses at 750 mg/kg/day. However, 
the minor differences were not considered adverse since there was no 
clear dose-response and the values (both findings) fell within 
historical control values. Furthermore, the findings were attributed to 
the associated decreases in maternal body weights. There were no 
treatment-related effects observed in dams or offspring in the 
developmental toxicity study in rabbits. In the reproduction toxicity 
study in rats, there were decreased body weights, body weight gains, 
and food consumption, as well as increased kidney weights and 
hypertrophy in both sexes at 500 mg/kg/day. Additionally, at 500 mg/kg/
day, transient decreases in pup body weights were observed on post-
natal day 4 pre-culling (F1 and F2 males) and post-natal day 7 (F1 
females and F2 males and females); however, by post-natal day 21, all 
treated groups were similar to controls. The decreases observed were 
associated with decreased maternal body weight and food consumption and 
were transient in nature; thus, they were not considered adverse
    3. Conclusion. EPA has determined that reliable data show the 
safety of infants and children would be adequately protected if the 
FQPA SF were reduced to 1x. That decision is based on the following 
findings:
    i. The toxicity database for florasulam is complete.
    ii. There is no indication that florasulam is a neurotoxic chemical 
and there is no need for a developmental neurotoxicity study or 
additional UFs to account for neurotoxicity.
    iii. There is no evidence that florasulam results in increased 
susceptibility in in utero rats or rabbits in the prenatal 
developmental studies or in young rats in the 2-generation reproduction 
study.
    iv. There are no residual uncertainties identified in the exposure 
databases. The dietary food exposure assessments were performed based 
on 100 PCT and tolerance-level residues. EPA made conservative 
(protective) assumptions in the ground and surface water modeling used 
to assess exposure to florasulam in drinking water. EPA used similarly 
conservative assumptions to assess post-application exposure of 
children as well as incidental oral exposure of toddlers. These 
assessments will not underestimate the exposure and risks posed by 
florasulam.

E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic dietary pesticide 
exposures are safe by comparing aggregate exposure estimates to the 
acute PAD (aPAD) and chronic PAD (cPAD). For linear cancer risks, EPA 
calculates the lifetime probability of acquiring cancer given the 
estimated aggregate exposure. Short-, intermediate-, and chronic-term 
risks are evaluated by comparing the estimated aggregate food, water, 
and residential exposure to the appropriate PODs to ensure that an 
adequate MOE exists.
    1. Acute risk. An acute aggregate risk assessment takes into 
account acute exposure estimates from dietary consumption of food and 
drinking water. No adverse effect resulting from a single oral exposure 
was identified and no acute dietary endpoint was selected. Therefore, 
florasulam is not expected to pose an acute risk.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
florasulam from food and water will utilize less than 1% of the cPAD 
for all population groups. Based on the explanation in Unit III.C.3., 
regarding residential use patterns, chronic residential exposure to 
residues of florasulam is not expected.
    3. Short-term risk. Short-term aggregate exposure takes into 
account short-term residential exposure plus chronic exposure to food 
and water (considered to be a background exposure level).
    Florasulam is currently registered for uses 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 florasulam.
    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 14,000 for 
children, 98,000 for the general U.S. population, and 114,000 for adult 
females. Because EPA's level of concern for florasulam is a MOE of 100 
or below, these MOEs are not of concern.
    4. Intermediate-term risk. Intermediate-term aggregate exposure 
takes into account intermediate-term residential exposure plus chronic 
exposure to food and water (considered to be a background exposure 
level).
    An intermediate-term adverse effect was identified; however, 
florasulam is not registered for any use patterns that would result in 
intermediate-term residential exposure. Intermediate-term risk is 
assessed based on intermediate-term residential exposure plus chronic 
dietary exposure. Because there is no intermediate-term residential 
exposure and chronic dietary exposure has already been assessed under 
the appropriately protective cPAD (which is at least as protective as 
the POD used to assess intermediate-term risk), no further assessment 
of intermediate-term

[[Page 35146]]

risk is necessary, and EPA relies on the chronic dietary risk 
assessment for evaluating intermediate-term risk for florasulam.
    5. Aggregate cancer risk for U.S. population. Based on the lack of 
evidence of carcinogenicity in two adequate rodent carcinogenicity 
studies, florasulam is not expected to pose a cancer risk to humans.
    6. 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 florasulam residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology (capillary gas chromatography and 
mass selective detection (GC-MSD)) 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; email 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 (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 florasulam on teff.

C. Response to Comments

    A single comment was received that appeared to be in support of the 
petition and read in part that ``the proposed regulation of pesticide 
residuals is . . . a very reasonable proposal.'' The commenter also 
expressed concern regarding the consequences for not meeting the 
residue levels. The commenter's concern is outside the scope of this 
rulemaking, which is concerned with assessing the safety of these 
tolerances.

V. Conclusion

    Therefore, tolerances are established for residues of florasulam, 
including its metabolites and degradates, in or on teff, forage at 0.05 
ppm; teff, grain at 0.01 ppm; teff, hay at 0.05 ppm; and teff, straw at 
0.05 ppm.
    In addition, in accordance with Agency policy, EPA is revising the 
introductory language in paragraph (a) to clarify (1) that, as provided 
in FFDCA section 408(a)(3), the tolerance covers metabolites and 
degradates of florasulam not specifically mentioned; and (2) that 
compliance with the specified tolerance levels is to be determined by 
measuring only the specific compounds mentioned in the tolerance 
expression. 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.

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), nor is it considered a 
regulatory action under Executive Order 13771, entitled ``Reducing 
Regulations and Controlling Regulatory Costs'' (82 FR 9339, February 3, 
2017). 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).
