ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation establishes time-limited tolerances for 
residues of triclopyr in or on sugarcane. This action is in response to 
EPA's granting of an emergency exemption under the Federal Insecticide, 
Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide 
on sugarcane. This regulation establishes a maximum permissible level 
for residues of triclopyr in or on this commodity. The time-limited 
tolerance will expire on December 31, 2020.

DATES: This regulation is effective June 8, 2017. Objections and 
requests for hearings must be received on or before August 7, 2017, and 
must be filed in accordance with the instructions provided in 40 CFR

II. Background and Statutory Findings

    EPA, on its own initiative, in accordance with FFDCA sections 
408(e) and 408(l)(6) of, 21 U.S.C. 346a(e) and 346a(1)(6), is 
establishing a time-limited tolerance for residues of triclopyr (2-
[(3,5,6-trichloro-2-pyridinyl)oxy]acetic acid), including its 
metabolites and degradates in or on sugarcane, cane at 40 parts per 
million (ppm). This time-limited tolerance will expire on December 31, 
2020.
    Section 408(l)(6) of FFDCA requires EPA to establish a time-limited 
tolerance or exemption from the requirement for a tolerance for 
pesticide chemical residues in food that will result from the use of a 
pesticide under an emergency exemption granted by EPA under FIFRA 
section 18. Such tolerances can be established without providing notice 
or period for public comment. EPA does not intend for its actions on 
FIFRA section 18 related time-limited tolerances to set binding 
precedents for the application of FFDCA section 408 and the safety 
standard to other tolerances and exemptions. Section 408(e) of FFDCA 
allows EPA to establish a tolerance or an exemption from the 
requirement of a tolerance on its own initiative, i.e., without having 
received any petition from an outside party.
    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

[[Page 26600]]

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 . . . .''
    Section 18 of FIFRA authorizes EPA to exempt any Federal or State 
agency from any provision of FIFRA, if EPA determines that ``emergency 
conditions exist which require such exemption.'' EPA has established 
regulations governing such emergency exemptions in 40 CFR part 166.

III. Emergency Exemption for Triclopyr on Sugarcane and FFDCA 
Tolerances

    The Louisiana Department of Agriculture and Forestry (LDAF) 
requested a quarantine emergency exemption for the use of triclopyr on 
sugarcane to control Merrill's nightshade (Solanum merrillianum Liou). 
Merrill's nightshade is a non-native plant that was introduced into the 
United States sometime before its discovery in 1976, where it has 
become a pest of importance in sugarcane in Louisiana. According to 
LDAF, Merrill's nightshade has been confirmed in 17 of the 24 sugarcane 
producing parishes. Substantial economic damage is occurring and has 
been documented at 39% reduction of tonnage and 49% reduction of 
recoverable sugar losses per acre.
    After having reviewed the submission, EPA determined that an 
emergency condition exists for this State, and that the criteria for 
approval of an emergency exemption are met. EPA has authorized a 
quarantine exemption under FIFRA section 18 for the use of triclopyr on 
sugarcane for control of Merrill's nightshade in Louisiana.
    As part of its evaluation of the emergency exemption application, 
EPA assessed the potential risks presented by residues of triclopyr in 
or on sugarcane. In doing so, EPA considered the safety standard in 
FFDCA section 408(b)(2), and EPA decided that the necessary tolerances 
under FFDCA section 408(l)(6) would be consistent with the safety 
standard and with FIFRA section 18. Consistent with the need to move 
quickly on the emergency exemption in order to address an urgent, non-
routine situation and to ensure that the resulting food is safe and 
lawful, EPA is issuing these tolerances without notice and opportunity 
for public comment as provided in FFDCA section 408(l)(6). Although 
these time-limited tolerances expire on December 31, 2020, under FFDCA 
section 408(l)(5), residues of the pesticide not in excess of the 
amounts specified in the tolerance remaining in or on sugarcane after 
that date will not be unlawful, provided the pesticide was applied in a 
manner that was lawful under FIFRA, and the residues do not exceed a 
level that was authorized by these time-limited tolerances at the time 
of that application. EPA will take action to revoke these time-limited 
tolerances earlier if any experience with, scientific data on, or other 
relevant information on this pesticide indicate that the residues are 
not safe.
    Because this time-limited tolerance is being approved under 
emergency conditions, EPA has not made any decisions about whether 
triclopyr meets FIFRA's registration requirements for use on sugarcane 
or whether permanent tolerances for this use would be appropriate. 
Under these circumstances, EPA does not believe that this time-limited 
tolerance decision serves as a basis for registration of triclopyr by a 
State for special local needs under FIFRA section 24(c), nor does this 
tolerance by itself serve as the authority for persons in any State 
other than Louisiana to use this pesticide on the applicable crop under 
FIFRA section 18, absent the issuance of an emergency exemption 
applicable within that State. For additional information regarding the 
emergency exemption for triclopyr, contact the Agency's Registration 
Division at the address provided under FOR FURTHER INFORMATION CONTACT.

IV. 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 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 expected as a result of this emergency exemption request and 
the time-limited tolerances for residues of triclopyr, including its 
metabolites and degradates on sugarcane, cane at 40 ppm. EPA's 
assessment of exposures and risks associated with establishing time-
limited tolerances follows.

A. 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://www.epa.gov/pesticides/factsheets/riskassess.htm.
    A summary of the toxicological endpoints for triclopyr used for 
human risk assessment is discussed in Table 1 of the final rule 
published in the Federal Register of February 25, 2016, (81 FR 9353, 
9355-56) (FRL-9941-87).

B. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to triclopyr, EPA considered

[[Page 26601]]

exposure under the time-limited tolerances established by this action 
as well as all existing triclopyr tolerances in 40 CFR 180.417. EPA 
assessed dietary exposures from triclopyr in food as follows:
    i. Acute exposure. Acute effects were identified for triclopyr. In 
estimating acute dietary exposure, EPA used food consumption 
information from the United States Department of Agriculture (USDA) 
2003-2008 National Health and Nutrition Examination Survey, What We Eat 
in America (NHANES/WWEIA) and the Dietary Exposure Evaluation Model-
Food Commodity Intake Database (DEEM-FCID), version 3.16. As to residue 
levels in food, EPA performed the acute analysis using DEEM-FCID to 
estimate the dietary exposure of the general U.S. population and 
various population subgroups. The acute assessment was unrefined, 
assuming that triclopyr residues are present in all commodities at 
tolerance levels and that 100% of all crops are treated (100% CT). DEEM 
version 7.81 default processing factors were used to estimate residues 
in all processed commodities. Drinking water was incorporated directly 
into the dietary assessment.
    ii. Chronic exposure. In conducting the chronic dietary exposure 
assessment EPA used the food consumption data from the USDA 2003-2008 
National Health and Nutrition Examination Survey, What We Eat in 
America (NHANES/WWEIA) and the Dietary Exposure Evaluation Model-Food 
Commodity Intake Database (DEEM-FCID), version 3.16. As to residue 
levels in food, EPA performed the chronic analysis using DEEM-FCID to 
estimate the dietary exposure of the general U.S. population and 
various population subgroups. The chronic assessment was slightly 
refined, assuming that triclopyr residues are present in all 
commodities at tolerance levels (100% CT) except milk. An anticipated 
residue calculated from a recently submitted livestock feeding study 
was used for milk.
    iii. Cancer. For the reasons discussed in a previous triclopyr 
tolerance rule February 25, 2016 (81 FR 9353, 9356) (FRL-9941-87), EPA 
has concluded that quantification of risk using a non-linear approach 
will adequately account for all chronic toxicity, including potential 
carcinogenicity that could result from exposure to triclopyr. 
Therefore, a separate dietary exposure assessment for the purpose of 
assessing cancer risk is unnecessary.
    iv. Anticipated residue and percent crop treated (PCT) information. 
Section 408(b)(2)(E) of FFDCA authorizes EPA to use available data and 
information on the anticipated residue levels of pesticide residues in 
food and the actual levels of pesticide residues that have been 
measured in food. If EPA relies on such information, EPA must require 
pursuant to FFDCA section 408(f)(1) that data be provided 5 years after 
the tolerance is established, modified, or left in effect, 
demonstrating that the levels in food are not above the levels 
anticipated. For the present action, EPA will issue such data call-ins 
as are required by FFDCA section 408(b)(2)(E) and authorized under 
FFDCA section 408(f)(1). Data will be required to be submitted no later 
than 5 years from the date of issuance of these tolerances.
    For this time-limited tolerance rule, the Agency assumed 100% crop 
treated for all crops.
    2. Dietary exposure from drinking water. EPA calculated and 
required setback distances from the application site to the functional 
potable water intake in order to maintain average drinking water 
concentration levels below 400 parts per billion (ppb). Since potable 
water intakes are required to be turned off until triclopyr 
concentration levels are below 400 ppb, EPA has determined that for 
acute and chronic dietary risk assessments, the water concentration 
value of 400 ppb is appropriate to use to assess the contribution to 
drinking water.
    Modeled estimates of drinking water concentrations were directly 
entered into the dietary exposure model. For acute dietary risk 
assessment, the water concentration value of 400 ppb was used to assess 
the contribution to drinking water. For chronic dietary risk 
assessment, the water concentration value of 400 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).
    Triclopyr is currently registered for the following uses that could 
result in residential exposures: aquatic and turf areas. EPA assessed 
residential exposure using the following assumptions: Residential 
exposure is not anticipated from the proposed Section 18 emergency use 
for sugarcane. However, residential exposures are anticipated from 
currently registered uses of triclopyr. Exposures are expected for 
adults who apply triclopyr-containing products and for adults and 
children from post-application exposure in residential areas previously 
treated with triclopyr. These uses have all been previously assessed 
and have resulted in no risk estimates of concern for both handler and 
post-application exposures (L. Venkateshwara; 04-AUG-2015; D426070). 
Further information regarding EPA standard assumptions and generic 
inputs for residential exposures may be found at: http://www.epa.gov/pesticides/trac/science/trac6a05.pdf.
    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 substances 
that have a common mechanism of toxicity.''
    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 triclopyr and any other 
substances.
    3,5,6-trichloro-2-pyridinol, commonly known as TCP, is a metabolite 
of triclopyr, chlorpyrifos, and chlorpyrifos-methyl. Risk assessment of 
TCP was conducted in 2002, and the previous conclusions that the acute 
and chronic dietary aggregate exposure estimates are below EPA's LOC 
are still valid since the tolerances changes will not have a noticeable 
effect on dietary exposures to TCP. 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 Web site at http://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.

C. 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 FQPA Safety 
Factor (SF). In applying this provision, EPA either retains the default 
value of 10X, or uses a different additional SF when reliable data 
available to EPA support the choice of a different factor.
    2. Prenatal and postnatal sensitivity. There is evidence of 
increased qualitative susceptibility to offspring from triclopyr 
exposure in the rat two-generation reproduction study based on 
increased incidence of rare pup

[[Page 26602]]

malformations observed in the presence of parental toxicity. There is 
also potential qualitative susceptibility in the rat developmental 
toxicity study; however, the evidence was not as conclusive as the 
reproduction toxicity study. Concern is low since effects are well-
characterized with clearly established no-observed adverse-effect 
level/lowest-observed adverse-effect level (NOAEL/LOAEL) values, 
effects were seen in the presence of parental toxicity, and selected 
endpoints are protective of the observed effects.
    3. Conclusion. EPA has determined that reliable data show that the 
safety of infants and children would be adequately protected if the 
FQPA SF were reduced to 1X, with the exception for inhalation exposures 
where the FQPA SF is retained at 10X. These decisions are based on the 
following findings:
    i. The toxicity database for triclopyr is adequate for FQPA SF 
consideration. For assessing risks associated with inhalation 
exposures, the FQPA SF is retained at 10X to incorporate the database 
uncertainty factor (UFDB) to account for the lack of a 
subchronic inhalation toxicity study.
    ii. There is no evidence of neurotoxicity from triclopyr exposure.
    iii. Selected endpoints are protective of any observed pre- or 
post-natal offspring susceptibility.
    iv. The exposure databases are sufficient and unlikely to 
underestimate exposure. These assessments will not underestimate the 
exposure and risks posed by triclopyr.

D. 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. Using the exposure assumptions discussed in this 
unit for acute exposure, the acute dietary exposure from food and water 
to triclopyr will occupy 54% of the aPAD for females 13-49 years old 
and 8% of the aPAD for all infants less than one year old (<1 year 
old), the population subgroups receiving the greatest exposure.
    2. Chronic risk. Using the exposure assumptions described in this 
unit for chronic exposure, EPA has concluded that chronic exposure to 
triclopyr from food and water will utilize 47% of the cPAD for all 
infants less than one year old (<1 year old), the population group 
receiving the greatest exposure. Based on the explanation in the unit 
regarding residential use patterns, chronic residential exposure to 
residues of triclopyr 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). Triclopyr 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 triclopyr.
    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 120 for children 
one year old to less than two years old (1 to <2 years old) (dietary 
exposures with potential post-application incidental oral exposure 
resulting from the registered turf use). Because EPA's level of concern 
for triclopyr is a MOE of 100 or below, these MOEs are not of concern. 
For adults and children 3 to <6 years old, an aggregate risk index 
(ARI) is used since the POD for the oral and inhalation routes of 
exposure are the same, but the LOC values for oral (MOE<100) and 
inhalation (MOE<1000) exposures are different. The ARIs are 3.6 for 
children 3 to <6 years old (dietary exposure with post-application 
inhalation and ingestion from aquatic use), and 1.4 for adults (dietary 
exposure with handler inhalation exposure from turf use). Since EPA's 
level of concern is an ARI below 1, these ARIs are not of concern.
    4. Intermediate-term risk. Intermediate-term aggregate exposure 
takes into account intermediate-term non-dietary, non-occupational 
exposure plus chronic exposure to food and water (considered to be a 
background exposure level).
    Although triclopyr is currently registered for uses that could 
result in intermediate-term residential exposure, the Agency has 
determined that a quantified intermediate-term aggregate assessment is 
unnecessary since the short-and intermediate-term PODs are the same and 
the short-term aggregate provides a worst-case estimate of residential 
exposures. For these reasons, the short-term aggregate is protective of 
the longer-term exposures.
    5. Aggregate cancer risk for U.S. population. A cancer aggregate 
risk assessment was not performed because a separate cancer assessment 
was not warranted (see Section B.1.iii).
    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 triclopyr residues.

V. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodologies (Methods ACR 77.2 and ACR 77.4 
using gas chromatography with electron-capture detection (GC/ECD); 
Method GRM 97.02 using gas chromatography with mass-spectrometry 
detection (GC/MS)) are available to enforce the tolerance expression. 
The Food and Drug Administration (FDA) PESTDATA database dated 1/94 
(Pesticide Analytical Manual (PAM) Vol. 1, Appendix 1) indicates 
triclopyr is completely recovered greater than 80% (>80%) using multi-
residue method PAM Vol. 1 Section 402. Data pertaining to multi-residue 
methods testing of triclopyr and its metabolites through Protocols B, 
C, D and E have been submitted and forwarded to FDA.
    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

[[Page 26603]]

EPA explain the reasons for departing from the Codex level.
    The Codex has not established a MRL for residues of triclopyr.

VI. Conclusion

    Therefore, a time-limited tolerance is established for residues of 
triclopyr, (2-[(3,5,6-trichloro-2-pyridinyl)oxy]acetic acid), including 
its metabolites and degradates in or on sugarcane, cane at 40 ppm. This 
tolerance will expire on December 31, 2020.

VII. Statutory and Executive Order Reviews

    This action establishes tolerances under FFDCA sections 408(e) and 
408(l)(6). 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 in accordance 
with FFDCA sections 408(e) and 408(l)(6), 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).

VIII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
EPA has submitted 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).
