II. Petition for Tolerance

    In the Federal Register of May 6, 2009 (74 FR 20947) (FRL-8412-7),
EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 U.S.C.
346a(d)(3), announcing the filing of a pesticide petition (PP 8F7455)
by Dow AgroSciences, 9330 Zionsville Rd., Indianapolis, IN 46268. The
petition requested that 40 CFR 180.610 be amended by establishing
tolerances for combined residues of the herbicide aminopyralid, 4-
amino-3,6-dichloro-2-pyridinecarboxylic acid, and its glucose
conjugate, expressed as total parent, in or on corn, forage at 0.30
parts per million (ppm); corn, grain at 0.20 ppm; and corn, stover at
0.20 ppm. That notice referenced a summary of the petition prepared by
Dow AgroSciences, the registrant, which is available to the public in
the docket, http://www.regulations.gov. Comments were

received on the notice of filing. EPA's response to these comments is
discussed in Unit IV.C.
    Based upon review of the data supporting the petition, EPA has
revised the corn commodity terminology and tolerance expression for
aminopyralid. The reasons for these changes are explained in Unit IV.D.

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 section 408(b)(2)(D) of FFDCA, and the factors
specified in section 408(b)(2)(D) of FFDCA, EPA has reviewed the
available scientific data and other relevant information in support of
this action. EPA has sufficient data to assess the hazards of and to
make a determination on aggregate exposure for the petitioned-for
tolerances for residues of aminopyralid, including its metabolites and
degradates, on corn, field, forage at 0.30 ppm; corn, field, grain at
0.20 ppm; and corn, field, stover at 0.20 ppm. EPA's assessment of
exposures and risks associated with establishing tolerances 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.
    The toxicology database for aminopyralid includes toxicity studies
conducted with the acid (XDE-750) and the triisopropanolammonium (TIPA)
salt (GF-871). The acute toxicity data indicate that both the acid and
salt have low toxicity via oral, dermal, and inhalation routes of
exposure; and that neither is a skin irritant or skin sensitizer. The
TIPA salt is not irritating to the eye; however, aminopyralid acid is
severely irritating to the eye.
    Longer term studies indicate that the stomach, ileum, and cecum are
targets for aminopyralid. In a subchronic feeding study in rats (XDE-
750), hyperplasia of the mucosal epithelium of the ileum and cecum was
observed at the highest dose tested (HDT) of 1,000 milligrams/
kilograms/day (mg/kg/day). Chronic exposure in rats (XDE-750) also
resulted in hyperplasia of the mucosal epithelium, along with cecal
enlargement and decreased body weights at a lower dose of 500 mg/kg/
day. Hypertrophy and hyperplasia of the mucosal epithelium were seen
after subchronic exposure in dogs (XDE-750) at the HDT of 929 mg/kg/
day. Thickening of the stomach mucosa (females), hyperplasia and
hypertrophy of the mucosal epithelium, slight lymphoid hyperplasia of
the gastric mucosa, and very slight/slight chronic mucosal inflammation
were observed in dogs after chronic exposure at the HDT of 967 mg/kg/
day. No adverse effects were observed in subchronic or chronic feeding
studies in mice.
    Stomach effects were also observed in a developmental toxicity
study in rabbits conducted with the acid (XDE-750). Ulcers and erosions
were seen in the glandular mucosa of the stomach at 500 mg/kg/day in
maternal animals. Other effects noted were decreased body weights and
incoordinated gait. No developmental effects were seen in fetuses at
500 mg/kg/day. The high dose group was removed from the study because
of the severity of the clinical signs that were observed (incoordinated
gait, significant body weight losses, and decreased food intake). In
another developmental rabbit study conducted with the TIPA salt (GF-
871), severe inanition (exhaustion from lack of food), body weight
loss, decreased fecal output, and incoordinated gait were observed at
260 mg/kg/day. At 520 mg/kg/day, decreased fetal body weights were
observed. No effects were noted in developmental toxicity studies in
rats with XDE-750 or GF-871 or a reproduction study in rats with XDE-
750. There was no qualitative or quantitative evidence of increased
susceptibility of fetuses or offspring in any of the developmental and
reproduction toxicity studies conducted with aminopyralid.
    No systemic toxic effects were observed in a 28-day dermal toxicity
study in rats with XDE-750; however, dermal toxicity was indicated by
slight epidermal hyperplasia in males at 1,000 mg/kg/day.
    In an acute neurotoxicity study in rats (XDE-750), fecal soiling in
males and urine soiling in females were observed at 2,000 mg/kg/day. No
adverse effects were observed in a chronic neurotoxicity study in rats
up to 1,000 mg/kg/day.
    Aminopyralid is classified as ``not likely to be carcinogenic to
humans.'' No increase in any tumors was found in carcinogenicity
studies in rats and mice. Aminopyralid was negative in all mutagenicity
studies, except for an in vitro chromosome aberration assay in Sprague
Dawley rats. In this assay, XDE-750 induced chromosome aberrations, but
only at cytotoxic concentrations. The clastogenic response was induced
secondarily to toxicity.
    Specific information on the studies received and the nature of the
adverse effects caused by aminopyralid 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 ``Aminopyralid. Human Health Risk
Assessment for the Proposed Use on Field Corn (PP#8F7455)'' at page 40
in docket ID number EPA-HQ-OPP-2009-0141.

B. Toxicological Endpoints

    For hazards that have a threshold below which there is no
appreciable risk, a toxicological point of departure (POD) is
identified as the basis for derivation of reference values for risk
assessment. The POD may be defined as the highest dose at which no
adverse effects are observed (the NOAEL) in the toxicology study
identified as appropriate for use in risk assessment. However, if a
NOAEL cannot be determined, the lowest dose at which adverse effects of
concern are identified (the LOAEL) or a benchmark dose (BMD) approach
is sometimes used for risk assessment. Uncertainty/safety factors (UFs)
are used in conjunction with the POD to take into account uncertainties
inherent in the extrapolation from laboratory animal data to humans and
in the variations in sensitivity among members of the human population
as well as other unknowns. Safety is assessed for acute and chronic
dietary risks by comparing aggregate food and water exposure to the
pesticide to the acute population adjusted dose (aPAD) and chronic
population adjusted dose (cPAD). The

aPAD and cPAD are calculated by dividing the POD by all applicable UFs.
Aggregate short-, intermediate-, and chronic-term risks are evaluated
by comparing food, water, and residential exposure to the POD to ensure
that the margin of exposure (MOE) called for by the product of all
applicable UFs is not exceeded. This latter value is referred to as the
level of concern (LOC).
    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
greater than that 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 aminopyralid used for
human risk assessment can be found at http://www.regulations.gov in the
document ``Aminopyralid: Human Health Risk Assessment for the Proposed
Use on Field Corn (PP#8F7455)'' at page 20 in docket ID number EPA-HQ-
OPP-2009-0141.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary
exposure to aminopyralid, EPA considered exposure under the petitioned-
for tolerances as well as all existing aminopyralid tolerances in 40
CFR 180.610. EPA assessed dietary exposures from aminopyralid in food
as follows:
    i. Acute exposure. Quantitative acute dietary exposure and risk
assessments are performed for a food-use pesticide, if a toxicological
study has indicated the possibility of an effect of concern occurring
as a result of a 1-day or single exposure. No such effects were
identified in the toxicological studies for aminopyralid; therefore, a
quantitative acute dietary exposure assessment is unnecessary.
    ii. Chronic exposure. In conducting the chronic dietary exposure
assessment EPA used the food consumption data from the U.S. Department
of Agriculture (USDA) 1994-1996 and 1998 Continuing Survey of Food
Intake by Individuals (CSFII). As to residue levels in food, EPA
assumed that residues are present in all commodities at the tolerance
level and that 100% of commodities are treated with aminopyralid. The
Dietary Exposure Evaluation Model (DEEM)(tm) 7.81 default concentration
factors were used to estimate residues of aminopyralid in processed
commodities.
    iii. Cancer. Based on the results of carcinogenicity studies in
rats and mice, EPA classified aminopyralid as ``not likely to be
carcinogenic to humans.'' Therefore, an exposure assessment to evaluate
cancer risk is unnecessary for this chemical.
    iv. Anticipated residue and percent crop treated (PCT) information.
EPA did not use anticipated residue or PCT information in the dietary
assessment for aminopyralid. Tolerance level residues and 100 PCT were
assumed for all food commodities.
    2. Dietary exposure from drinking water. The Agency used screening
level water exposure models in the dietary exposure analysis and risk
assessment for aminopyralid in drinking water. These simulation models
take into account data on the physical, chemical, and fate/transport
characteristics of aminopyralid. Further information regarding EPA
drinking water models used in pesticide exposure assessment can be
found at http://www.epa.gov/oppefed1/models/water/index.htm.
    Based on the First Index Reservoir Screening Tool (FIRST) and
Screening Concentration in Ground Water (SCI-GROW) models, the
estimated drinking water concentrations (EDWCs) of aminopyralid for
chronic exposures for non-cancer assessments (the only dietary exposure
scenario of concern for aminopyralid) are estimated to be 1.937 parts
per billion (ppb) for surface water and 0.63 ppb for ground water.
    Modeled estimates of drinking water concentrations were directly
entered into the dietary exposure model. For chronic dietary risk
assessment, the water concentration of value 1.937 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).
    Aminopyralid is currently registered for the following uses that
could result in residential exposures: Natural recreation areas, such
as wildlife management areas, campgrounds, trailheads and trails. EPA
assessed residential exposure using the following assumptions:
    Aminopyralid is not applied by homeowners to residential or
recreational settings; therefore, only post-application residential
exposures were considered. A dermal endpoint of concern has not been
identified for aminopyralid and postapplication inhalation exposure
following treatment of recreation areas is expected to be negligible
for adults and children. There is, however, the potential for short-
term postapplication oral exposure of children playing in areas treated
with aminopyralid. EPA assessed the following incidental oral exposure
scenarios: Hand-to-mouth transfer of residues; object-to-mouth transfer
of residues; and ingestion of soil containing aminopyralid residues.
    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.''
    EPA has not found aminopyralid to share a common mechanism of
toxicity with any other substances, and aminopyralid does not appear to
produce a toxic metabolite produced by other substances. For the
purposes of this tolerance action, therefore, EPA has assumed that
aminopyralid 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://
www.epa.gov/pesticides/cumulative.

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 Factors (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. The prenatal and postnatal
toxicity database for aminopyralid includes harmonized guideline rat
and rabbit developmental toxicity studies for both the acid and TIPA
salt of aminopyralid and a two-generation reproduction toxicity study
in rats conducted using aminopyralid acid. As discussed in Unit III.A
(Toxicological Profile), there is no

quantitative or qualitative evidence of increased susceptibility of
fetuses or offspring in any of these studies.
    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 aminopyralid is adequate to assess
pre- and postnatal toxicity. In accordance with 40 CFR part 158
Toxicology Data requirements, an immunotoxicity study (guideline
870.7800) is required for aminopyralid. In the absence of specific
immunotoxicity studies, EPA has evaluated the available aminopyralid
data to determine whether an additional uncertainty factor is needed to
account for potential immunotoxicity. The toxicology database for
aminopyralid does not show any evidence of treatment-related effects on
the immune system. The overall weight-of-evidence suggests that this
chemical does not directly target the immune system, and the Agency
does not believe that conducting a functional immunotoxicity study will
result in a lower POD than that currently used for overall risk
assessment. Therefore, a database uncertainty factor (UFDB) is not
needed to account for the lack of this study.
    ii. No evidence of neurotoxicity was observed in acute or chronic
neurotoxicity studies. Incoordinated gait, along with a lack of
ambulatory movement, was observed in developmental toxicity studies
(XDE-750 and GF-871) in rabbits at 500 mg/kg/day. However, the
incoordination was transient (complete resolution within 2 hours
postdosing) and considered to be a result of frank toxicity, rather
than a neurotoxic event. Additionally, no signs of neurotoxicity were
observed in other toxicity studies, and no evidence of quantitative or
qualitative susceptibility was observed in developmental toxicity
studies in rats or rabbits or a reproduction study in rats. Based on
these findings, EPA has concluded that there is no need for a
developmental neurotoxicity study or additional UFs to account for
neurotoxicity.
    iii. There is no evidence that aminopyralid results in increased
susceptibility in in utero rats or rabbits in the prenatal
developmental studies or offspring 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 aminopyralid in drinking water. EPA used
similarly conservative assumptions to assess postapplication exposure
of children as well as incidental oral exposure of toddlers. These
assessments will not underestimate the exposure and risks posed by
aminopyralid.

E. Aggregate Risks and Determination of Safety

    EPA determines whether acute and chronic pesticide exposures are
safe by comparing aggregate exposure estimates to the aPAD and cPAD.
The aPAD and cPAD represent the highest safe exposures, taking into
account all appropriate SFs. EPA calculates the aPAD and cPAD by
dividing the POD by all applicable UFs. For linear cancer risks, EPA
calculates the probability of additional cancer cases 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 POD to ensure that the MOE called for
by the product of all applicable UFs is not exceeded.
    1. Acute risk. An acute aggregate risk assessment takes into
account exposure estimates from acute 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,
aminopyralid 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
aminopyralid from food and water will utilize <1% of the cPAD for the
general U.S. population and all population subgroups, including
children 1 to 2 years old, the population group receiving the greatest
exposure. Based on the explanation in Unit III.C.3., regarding
residential use patterns, chronic residential exposure to residues of
aminopyralid 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). Aminopyralid
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 aminopyralid.
    Using the exposure assumptions described in this unit for short-
term exposures, EPA has concluded the combined short-term food, water,
and residential exposures aggregated result in aggregate MOEs of
between 25,000 and 33,000 for children's population subgroups. The
aggregate MOEs include dietary exposures from food and drinking water
as well as postapplication incidental oral exposure of children and
toddlers playing in recreational areas treated with aminopyralid.
Although short-term residential postapplication exposure of adults
could result from the use of aminopyralid, inhalation exposures are
expected to be negligible and a dermal endpoint of concern has not been
identified for aminopyralid. Therefore, the short-term aggregate risk
for adults is the sum of the risk from exposure to aminopyralid through
food and water, which has already been addressed, and will not be
greater than the chronic aggregate risk.
    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). Aminopyralid is not registered for any use patterns that would
result in intermediate-term residential exposure. Therefore, the
intermediate-term aggregate risk is the sum of the risk from exposure
to aminopyralid through food and water, which has already been
addressed, and will not be greater than the chronic aggregate risk.
    5. Aggregate cancer risk for U.S. population. Based on a lack of
evidence for carcinogenicity in mice and rats following long-term
dietary administration, aminopyralid is not expected to pose a cancer
risk.
    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 aminopyralid residues.

IV. Other Considerations

A. Analytical Enforcement Methodology

    Adequate enforcement methodology, Liquid Chromatography/Mass
Spectrometry/Mass Spectrometry (LC/MS/MS), Method GRM 07.07, 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:<PHONE_NUMBER>; e-mail address<EMAIL_ADDRESS>

B. International Residue Limits

    No Codex, Canadian or Mexican MRLs have been established for corn
commodities.

C. Response to Comments

    EPA received comments from an anonymous submitter objecting to
pesticides and other ``toxic'' chemicals generally and recommending
against any tolerances greater than zero for this product. The Agency
understands the commenter's concerns and recognizes that some
individuals believe that pesticides should be banned completely.
However, the existing legal framework provided by section 408 of the
FFDCA contemplates that tolerances greater than zero may be set when
persons seeking such tolerances or exemptions have demonstrated that
the pesticide meets the safety standard imposed by that statute. This
submitter's comments appear to be directed at the underlying statute
and not EPA's implementation of it; the citizen has made no contention
that EPA has acted in violation of the statutory framework.

D. Revisions to Petitioned-For Tolerances

    EPA has revised the commodity terms ``corn, forage,'' ``corn,
grain,'' and ``corn, stover,'' to read ``corn, field, forage,'' ``corn,
field, grain,'' and ``corn, field, stover'' to agree with the Agency's
Food and Feed Commodity Vocabulary.
    EPA is also revising the tolerance expression for existing
tolerances and the new tolerances on corn commodities to clarify the
chemical moieties that are covered by the tolerances and specify how
compliance with the tolerances is to be measured. Plant tolerances are
currently expressed in terms of ``free and conjugated residues of the
herbicide aminopyralid, 2-pyridine carboxylic acid, 4-amino-3,6-
dichloro-, calculated as aminopyralid.'' Livestock tolerances are
currently expressed in terms of ``residues of the herbicide
aminopyralid.'' The tolerance expression for plants is being revised to
make clear that the tolerances cover residues of aminopyralid, 4-amino-
3,6-dichloro-2-pyridinecarboxylic acid, including its metabolites and
degradates. Compliance with the tolerances is to be determined by
measuring only free and conjugated aminopyralid. Similarly, the
tolerance expression for livestock commodities is being revised to
clarify that the tolerances cover residues of aminopyralid, including
its metabolites and degradates, but that compliance with the tolerance
levels will be determined by measuring only aminopyralid.
    EPA has determined that it is reasonable to make these changes
final without prior proposal and opportunity for comment, because
public comment is not necessary, in that the changes have no
substantive effect on the tolerances, but rather are merely intended to
clarify the existing tolerance expressions.

V. Conclusion

    Therefore, tolerances are established for residues of aminopyralid,
4-amino-3,6-dichloro-2-pyridinecarboxylic acid, including its
metabolites and degradates, in or on corn, field, forage at 0.30 ppm;
corn, field, grain at 0.20 ppm; and corn, field, stover at 0.20 ppm.
Compliance with these tolerance levels is to be determined by measuring
only free and conjugated aminopyralid.

VI. Statutory and Executive Order Reviews

    This final rule establishes tolerances under section 408(d) of
FFDCA in response to a petition submitted to the Agency. The Office of
Management and Budget (OMB) has exempted these types of actions from
review under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993). Because this final rule has been
exempted from review under Executive Order 12866, this final rule is
not subject to Executive Order 13211, entitled Actions Concerning
Regulations That Significantly Affect Energy Supply, Distribution, or
Use (66 FR 28355, May 22, 2001) or Executive Order 13045, entitled
Protection of Children from Environmental Health Risks and Safety Risks
(62 FR 19885, April 23, 1997). This final rule does not contain any
information collections subject to OMB approval under the Paperwork
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any
special considerations under Executive Order 12898, entitled Federal
Actions to Address Environmental Justice in Minority Populations and
Low-Income Populations (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis
of a petition under section 408(d) of FFDCA, such as the tolerance in
this final rule, do not require the issuance of a proposed rule, the
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et
seq.) do not apply.
    This final rule directly regulates growers, food processors, food
handlers, and food retailers, not States or tribes, nor does this
action alter the relationships or distribution of power and
responsibilities established by Congress in the preemption provisions
of section 408(n)(4) of FFDCA. As such, the Agency has determined that
this action will not have a substantial direct effect on States or
tribal governments, on the relationship between the national government
and the States or tribal governments, or on the distribution of power
and responsibilities among the various levels of government or between
the Federal Government and Indian tribes. Thus, the Agency has
determined that Executive Order 13132, entitled Federalism (64 FR
43255, August 10, 1999) and Executive Order 13175, entitled
Consultation and Coordination with Indian Tribal Governments (65 FR
67249, November 9, 2000) do not apply to this final rule. In addition,
this final rule does not impose any enforceable duty or contain any
unfunded mandate as described under Title II of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Public Law 104-4).
    This action does not involve any technical standards that would
require Agency consideration of voluntary consensus standards pursuant
to section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272
note).

VII. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report to each House of the Congress and to
the Comptroller General of the United States. EPA will submit a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives, and the Comptroller General of the
United States prior to publication of this final rule in the Federal
Register. This final rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).

14 CFR Part 71

[Docket No. FAA-2020-0935; Airspace Docket No. 20-ANE-4]
RIN 2120-AA66

Establishment of Class E Airspace; Calais, ME

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

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

SUMMARY: This action amends Class E airspace extending upward from 700
feet above the surface for Calais Regional Heliport, Calais, ME. The
FAA discovered that necessary language was inadvertently omitted to the
description of the airspace that excluded airspace outside of the
United States.

DATES: Effective 0901 UTC, April 22, 2021. The Director of the Federal
Register approves this incorporation by reference action under Title 1
Code of Federal Regulations part 51, subject to the annual revision of
FAA Order 7400.11 and publication of conforming amendments.

SUPPLEMENTARY INFORMATION:

The Rule

    This amendment to 14 CFR part 71 amends Class E airspace for Calais
Regional Heliport, Calais, ME, by correcting the airspace description.
The description is amended from `That airspace extending upward from
700 feet above the surface of the earth within a 6-mile radius of
Calais Regional Heliport' to `That airspace extending upward from 700
feet above the surface of the earth within a 6-mile radius of Calais
Regional Heliport excluding that airspace outside of the United
States'. Accordingly, since this is an administrative change, and does
not affect the boundaries, altitudes, or operating requirements of the
airspace, notice and public procedures under 5 U.S.C. 553(b) are
unnecessary.
    Class E airspace designations are published in Paragraph 6005, of
FAA Order 7400.11E, dated July 21, 2020, and effective September 15,
2020, which is incorporated by reference in 14 CFR 71.1. The Class E
airspace designations listed in this document will be published
subsequently in the Order.

Regulatory Notices and Analyses

    The FAA has determined that this regulation only involves an
established body of technical regulations for which frequent and
routine amendments are necessary to keep them operationally current. It
therefore: (1) Is not a ``significant regulatory action'' under
Executive Order 12866; (2) is not a ``significant rule'' under DOT
Regulatory Policies and Procedures (44 FR 11034; February 26, 1979);
and (3) does not warrant preparation of a regulatory evaluation as the
anticipated impact is so minimal. Since this is a routine matter that
only affects air traffic procedures an air navigation, it is certified
that this rule, when promulgated, does not have a significant economic
impact on a substantial number of small entities under the criteria of
the Regulatory Flexibility Act.
