Clean Air Act Full Approval of Operating Permit Program; State of
Montana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final Rule.

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

SUMMARY: The EPA is promulgating full approval of the operating permit
program submitted by the State of Montana. Montana's operating permit
program was submitted for the purpose of meeting the federal Clean Air
Act (Act) directive that states develop, and submit to EPA, programs
for issuing operating permits to all major stationary sources and to
certain other sources within the states' jurisdiction.

DATES: This final rule is effective on January 22, 2001.

ADDRESSES: Copies of the documents relevant to this action are
available for public inspection during normal business hours at the
U.S. Environmental Protection Agency, Air and Radiation Program, Region
8, 999 18th Street, Suite 300, Denver, Colorado 80202-2466 and are also
available during normal business hours at the Montana Department of
Environmental Quality, 1520 East 6th Avenue, Helena, Montana 59620-
0901.

SUPPLEMENTARY INFORMATION:

I. Background

    As required under Title V of the Clean Air Act (``the Act'') as
amended (42 U.S.C. 7401 et seq.), EPA has promulgated rules that define
the minimum elements of an approvable state operating permit program
and the corresponding standards and procedures by which EPA will
approve, oversee, and withdraw approval of state operating permit
programs (see 57 FR 32250 (July 21, 1992)). These rules are codified at
40 Code of Federal Regulations (CFR) part 70 (part 70). Title V directs
states to develop, and submit to EPA, programs for issuing operating
permits to all major stationary sources and to certain other sources.
    The Act directs states to develop and submit operating permit
programs to EPA by November 15, 1993, and requires that EPA act to
approve or disapprove each program within 1 year after receiving the
submittal. The EPA's program review occurs pursuant to section 502 of
the Act (42 U.S.C. 7661a) and the part 70 regulations, which together
outline criteria for approval or disapproval. Where a program
substantially, but not fully, meets the requirements of part 70, EPA
may grant the program interim approval. If EPA has not fully approved a
program by two years after the November 15, 1993 date, or before the
expiration of an interim program approval, it must establish and
implement a federal program. The State of Montana was granted final
interim approval of its program on May 11, 1995 (see 60 FR 25143) and
the program became effective on June 12, 1995. Interim approval of the
Montana program expires on December 1, 2001.
    On June 13, 2000, EPA published a direct final rule in the Federal
Register promulgating full approval of the Operating Permit Program for
the State of Montana. See 65 FR 37049. The EPA received adverse
comments on the direct final rule, which are summarized and addressed
below. As stated in the Federal Register notice, if adverse comments
were received by July 13, 2000, the rule would be withdrawn and timely
notice would be published in the Federal Register. Therefore, due to
receiving adverse comments within the comment period, EPA withdrew the
final rule (65 FR 48391, August 8, 2000), and a proposed rule also
published in the Federal Register on June 13, 2000 served as the
proposed rule for this action. EPA will not institute a second comment
period on this document.
    In this rulemaking, EPA is taking final action to promulgate full
approval of the Montana Operating Permit Program.

II. Analysis of State Submission

    The Governor of Montana submitted an administratively complete
Title V operating permit program for the State of Montana on March 29,
1994. This program, including the operating permit regulations (Title
16, Chapter 8, Sub-Chapter 20, Sections 16.8.2001 through 16.8.2025,
inclusive, of the Administrative Rules of Montana (ARM)), substantially
met the requirements of part 70. EPA deemed the program
administratively complete in a letter to the Governor dated May 12,
1994. The program submittal included a legal opinion from the Attorney
General of Montana stating that the laws of the State provide adequate
legal authority to carry out all aspects of the program, and a
description of how the State would implement the program. The submittal
additionally contained evidence of proper adoption of the program
regulations, application and permit forms, and a permit fee
demonstration.
    EPA's comments noting deficiencies in the Montana program were sent
to the State in a letter dated October 3, 1994. The deficiencies were
segregated into those that would require corrective action prior to
interim program approval, and those that would require corrective
action prior to full program approval. The State committed to address
the program deficiencies that would require corrective action prior to
interim program approval in a letter dated October 20, 1994. The State
submitted these corrective actions with letters dated March 30, and
April 5, 1995. EPA reviewed these corrective actions and determined
them to be adequate for interim program approval.
    On January 15, 1998, Montana amended its operating permit program
to make the corrections identified as necessary in the May 11, 1995
Federal Register notice of final interim approval. These program
amendments, recodified at Title 17, Chapter 8, Sub-Chapter 12, Sections
1201, 1210, and 1213, ARM, were approved and adopted by the Montana
Board of Environmental Review on January 15, 1998. The revised program
regulations adequately addressed the problems identified in the May 11,
1995 Federal Register notice as requiring corrective action prior to
full program approval. The State also submitted evidence of proper
adoption of the revisions to its program regulations and a revised
Attorney General's opinion dated July 31, 1998. The revised program and
a request for full approval were submitted to EPA in a letter from the
Governor of Montana dated February 4, 1999. EPA notified Montana, in a
letter to the Department of Environmental Quality (DEQ) dated April 1,
1999, of two additional changes required for final approval. The DEQ
revised the administrative rules to implement the two requested changes
at Title 17, Chapter 8, Sub-Chapter 12, ARM. These amendments to Sub-
Chapter 12 were approved and adopted by the Board on March 17, 2000. On
April 12, 2000, the Governor of Montana submitted the revised program,
with proof of proper adoption, and requested full approval of its
operating permit program. EPA reviewed these changes and determined
that they were adequate to allow for full approval. On June 13, 2000,
EPA published a direct final rule in the Federal Register promulgating
full approval of the Operating Permit Program for the State of Montana.
See

[[Page 80786]]

65 FR 37049. The EPA received adverse comments on the direct final rule
and, on August 8, 2000, published withdrawal of the direct final rule
approval in the Federal Register. See 65 FR 48391.

III. Response to Comments

    The comments received on the June 13, 2000 direct final rule in the
Federal Register promulgating full approval of the Montana operating
permit program, and EPA's response to these comments are as follows:
    Comment 1: The commenter objected to EPA's approval of the Montana
Operating Permit Program because a state regulation allows the
administrative permit amendment process to be used for certain permit
changes that are not listed in a regulation but that the Montana
Department of Environmental Quality (``Department'') and EPA determine
are similar to the listed revisions. A list of revisions that qualify
for administrative permit amendment is found in Administrative Rules of
Montana (``ARM'') Section 17.8.1201(1)(a) through (d). This regulation
allows a source to use the administrative permit amendment process for
such non-substantive changes as change in address and correction of
typographical errors. The State has now added section (e), which allows
``any other change which the department and EPA have determined to be
similar'' to the listed revisions. The commenter objected that, by
allowing the Department and EPA to add other kinds of permit revisions
to the list without public notice and comment, the state regulation
violates EPA's regulations at 40 CFR Part 70 (``part 70 program'' or
``part 70 rules'').
    EPA Response: The definition of ``administrative permit amendment''
in EPA's regulations is found in 40 CFR 70.7(d)(1). The definition
provides, at Sec. 70.7(d)(1)(vi), that an administrative permit
amendment ``[i]ncorporates any other type of change which the
Administrator has determined as part of the approved part 70 program to
be similar to those in paragraphs (d)(1)(i) through (iv) of this
section'' 40 CFR 70.7(d)(1)(vi). The enumerated paragraphs (i) through
(iv) comprise a list of four non-substantive changes that are identical
to those in the State's list in section 17.8.1201(1) (a) through (d).
The comment suggests that the State cannot allow a source to use an
administrative permit amendment for a change that is not on the list,
unless the State first undergoes formal Title V program approval or
program revision approval, with public notice and comment, to add the
change to the list as a new requirement. The comment implies that ``as
part of the approved part 70 program'' in EPA's regulation means ``as
part of the part 70 program approval process.''
    EPA does not agree with this interpretation of our regulation. EPA
believes that the correct interpretation of the phrase ``as part of the
approved part 70 program'' refers to the fact that an unlisted change
must be evaluated in the context of the approved state program to
determine if it qualifies for an administrative amendment. The
regulation does not require that EPA must approve a formal revision of
the state program before a source can make a particular change
administratively, but rather requires the State to seek EPA's approval
for using the administrative permit amendment process for the change as
part of a specific permitting action. EPA believes that the regulation
allows the State to add to the list of non-substantive changes on a
case-by-case basis, if EPA agrees that a particular permit change is of
the same non-substantive nature as the enumerated list of changes that
automatically qualify for administrative permit amendment. EPA's
regulation thus allows exactly the kind of case-specific addition to
the list contemplated in the new section of Montana's rules, ARM
Section 17.8.1201(1)(e).
    Montana initially proposed a regulation that would allow the state
to make additions to the list without consulting EPA. EPA advised that
this would not be acceptable under Title V of the Clean Air Act
(``Act''), since 40 CFR 70.7(d)(1)(vi) requires that EPA must make a
determination that any additional change is similar to the enumerated
changes--in other words, to determine that the change is of such a
trivial or non-substantive nature that the administrative permit
amendment process would be appropriate. The regulation does not require
that the State must submit a list of anticipated non-substantive
changes to EPA for prior approval, as part of the Title V program
approval process, or that the State must revise its rules and submit
them for approval as a program revision whenever it encounters a non-
substantive change it believes should qualify for treatment as an
administrative permit amendment. The provision requires, instead, that
the State must notify EPA on a case-by-case basis whenever it
encounters a change it believes qualifies for the simpler
administrative amendment process (rather than the more complex minor or
significant permit modification process), so that EPA can decide if we
agree that the change qualifies for such treatment. If we do not agree
that the administration permit amendment process is appropriate for a
particular permit change, we can advise the State of our disapproval at
the draft permit stage of the operating permit process, or we can
object to the proposed permit during our 45-day review and thus prevent
the permit's issuance. If the permit has already been issued, we can
require the state to re-open the permit to delete an unacceptable
administrative permit amendment and instead process the change as a
minor or significant permit revision.
    We appreciate the concern expressed in the comment that the list
should not encompass substantive permit changes. EPA would not approve
as an administrative permit amendment any non-substantive change to a
Title V permit. We anticipate that the authority to add to the list of
administrative permit amendments will be used only infrequently.
    Comment 2. a.: The commenter objected that allowing an emission
threshold of five tons per year of any pollutant other than a hazardous
air pollutant in the State's definition of ``insignificant emission
unit'' exceeds the two-ton per year threshold that EPA has set in rules
for federal operating permits, 40 CFR part 71 (``part 71 program'' or
``part 71 rules''). The commenter also stated that the two-ton per year
threshold was accepted in many other states. In the Federal Register
notice proposing interim approval, EPA stated that Montana would need
to provide a demonstration to show why a higher threshold of five tons
per year would be insignificant. See 60 FR 25143-25144 (May 11, 1995).
    EPA Response: Insignificant emissions units are emitting units at a
source that emit ``insignificant'' levels of emissions. For such units,
the State may allow permit applicants to omit a full description of the
units in their permit applications. However, there are several caveats.
The applicant must still list the insignificant activity in its
application and must include complete information about such unit if it
is or may be subject to any applicable requirements. The pertinent
provision of the part 70 rules provides: ``the Administrator may
approve as part of a State program a list of insignificant activities
and emissions levels which need not be included in permit applications.
However, for insignificant activities which are exempted because of
size or production rate, a list of such insignificant activities must
be included in the application. An application may not omit information
needed to determine the applicability

[[Page 80787]]

of, or to impose, any applicable requirement * * *.'' 40 CFR 70.5(c).
    This provision of the part 70 rules does not set a ceiling on the
level of emissions that will be considered ``insignificant.'' EPA has
allowed states, including Montana, to determine what the state
considers to be ``insignificant'' for the limited purpose of omitting
certain information from the permit application. The comparable section
in the part 71 rules, 40 CFR 71.5(c)(11), does set such a ceiling:
``Potential to emit of regulated air pollutants, excluding HAP
[hazardous air pollutants] for any single emissions unit shall not
exceed 2 tpy [tons per year].'' 40 CFR 71.5(c)(11)(ii)(A). This
numerical limit applies only to federal operating permits, however, not
to state operating permits or state operating permit programs. EPA's
part 71 rules establish the requirements for the operating permits that
EPA issues in Indian country or anywhere else when EPA is the
permitting agency. The part 71 rules do not establish minimum
requirements for state operating permit programs; state programs may
differ from the federal program and may still be approved as long as
they meet the applicable state program requirements, which are found in
40 CFR part 70.
    The Montana operating permit program differs from the federal
program in this respect, but we believe it fully satisfies the program
requirements of 40 CFR part 70. The part 70 rules allow permit
applicants to omit certain information about ``insignificant emissions
units'' from their permit application. Montana's rules make clear,
however, that if an emissions unit is subject to an applicable
requirement other than a generally applicable requirement that applies
to all sources, the unit may not be considered an insignificant
emissions unit, no matter what its size may be. In other words, a unit
emitting five tons per year or less of a regulated pollutant may not be
treated as an insignificant emissions unit, if it is subject to a unit-
specific limit or a plant-wide applicability limit. Such a unit can
only be considered ``insignificant'' if it is subject to a state-wide
regulation, such as a generic limit on opacity, or to no applicable
requirements at all. And if a unit emitting five tons per year or less
does not qualify for ``insignificant'' status because it is subject to
a source-specific limit, the applicant must provide all relevant
information about the unit in the permit application, not simply
information necessary to determine the applicability of the applicable
requirement. In this respect, Montana's regulation is actually more
stringent than EPA's and provides more protection for the public's
right to know than EPA's regulation does. In any case, we believe there
is no conflict with EPA's part 70 rules.
    In response to EPA's request that the State provide justification
for using a five-ton per year cut-off, the Department stated,
``Experience has demonstrated that individual emitting units that are
not subject to applicable requirements other than generally applicable
requirements, and whose potential emissions are less than 5 tpy, have
such limited impact that they can be considered insignificant.'' Based
on our knowledge of Montana's industrial sources, we agree with the
Sates's assessment. The Department also noted that both 40 CFR part 70
and EPA's July 10, 1995 guidance memorandum entitled, ``White Paper for
Streamlined Development of Part 70 Permit Applications'' ``White Paper
I''), allow states discretion in selecting an appropriate
insignificance level for their Title V programs; and EPA has approved
levels higher than two tons per year in some other states. We are aware
of at least nine states, including Ohio, Florida, and Tennessee, and
ten local permitting authorities with approved Title V programs, where
EPA has allowed five tons per year as the cut-off for ``insignificant''
status. Some other states have a varying level depending on the
pollutant (five tons per year for carbon monoxide in Washington State,
for example) or an altogether different formula, based on pollutant or
process, for determining insignificant levels. We conclude that Montana
has adequately justified its use of five tons per year as a ceiling.
    Comment 2. b.: For hazardous air pollutants, the commenter objected
that Montana defines insignificant emissions as less than 500 pounds
per year, whereas EPA's part 71 rules provide that the insignificance
threshold for hazardous air pollutants cannot exceed 1000 pounds per
year or the de minimis level established under section 112(g) of the
Act, whichever is less.
    EPA Response: The comment implies that the part 71 rules establish
minimum requirements for state operating permit programs. They do not.
State operating permit programs must satisfy the requirements of 40 CFR
part 70, not 40 CFR part 71. The requirements of the two programs are
not, and do not need to be, identical. In particular, the part 70 rules
do not require that states adopt a particular cut-off for emissions of
hazardous air pollutants from ``insignificant emissions units.''
Although the part 71 rules do establish a cut-off, that ceiling applies
to federal operating permits only. In fact, the Montana regulation
establishes a more stringent cut-off than the federal level: 500 pounds
per year in ARM section 17.8.1201(22)(a)(iii), as opposed to 1000
pounds per year in 40 CFR part 71.
    The commenter recognizes that a level even lower than 500 pounds
per year could be established under the part 71 rules, as a
determination of a de minimis increase in emissions pursuant to section
112(g)(1)(A) of the Act: To date, however, EPA has not implemented the
modification provisions of section 112(g) of the Act: EPA has not
published guidance under section 112(g)(1)(B) of the Act establishing
de minimis levels of emission increases for purposes of applying
offsets under section 112(g)(1)(A) of the Act. Therefore, the
establishment of an ``insignificant'' level under the part 71 program
which would be lower than 1,000 pounds per year, let alone 500 pounds
per year, remains a merely hypothetical possibility. EPA believes that
the Montana ceiling for insignificant emissions of hazardous air
pollutants is more stringent than the federal requirement and will
adequately protect the public interest in disclosure of information
about hazardous air pollutants.
    Comment 3: The commenter stated that Montana's rules still do not
adequately assure that any monitoring data or other credible evidence
can be used to determine compliance and for direct enforcement. The
commenter expressed a concern that the wording of ARM 17.8.1213(2),
which requires that any data ``generated as a condition of the permit''
may be used to demonstrate compliance with the conditions of the permit
and may be used for direct enforcement, might be interpreted to limit
evidence of noncompliance only to monitoring or testing data required
by the permit.
    EPA Response: EPA does not agree with the suggested interpretation
of ARM 17.8.1213(2). We do not believe that the provision, by its terms
or by implication, precludes the use of other kinds of evidence to show
compliance or noncompliance with applicable requirements. We believe
that the provision makes clear that, if the permit requires testing or
monitoring, the results of such testing or monitoring may be used as
evidence of noncompliance regardless of the effect of any other rule.
EPA does agree, however, that Montana must develop a credible evidence
rule to eliminate any possibility of ambiguity in its regulations and
thus ensure that all evidence of noncompliance may be used

[[Page 80788]]

for purposes of direct enforcement, as long as that evidence is
credible. Montana is in the process of developing and adopting a
credible evidence rule, several versions of which were available for
public comment this past summer.
    Comment 4: The commenter stated that the State must certify its
ability to require annual certifications from part 70 sources regarding
proper implementation of their Risk Management Plans (RMP) under
section 112(r) of the Act, and must provide a compliance schedule for
sources that fail to submit the required plan. EPA's full approval
notice does not indicate whether this requirement was in fact met, but
merely indicates that ``the State will include a statement listing 40
CFR 68.215(a) as an applicable requirement in all Title V operating
permits.'' There is no indication that the State has in fact committed
to do this or is legally authorized and obligated to do so.
    EPA Response: EPA's full approval notice should have made clear
that the Governor of Montana, in a letter dated February 4, 1999, made
a commitment to require annual certifications from sources regarding
their compliance with all program requirements related to accident
prevention, emergency response, and risk management plans under section
112(r) of the Act, and to provide compliance schedules for any sources
that fail to submit their required plan to EPA. The letter stated,
``The department [of Environmental Quality] will include a statement
listing 40 CFR 68.215(a) as an applicable requirement in all title V
operating permits.'' The referenced Sec. 68.215(a) of Title 40 of the
Code of Federal Regulations requires that each source subject to both
section 112(r) of the Act and Title V of the Act must have, as
conditions of its operating permit, a statement listing all of 40 CFR
part 68 (``Chemical Accident Prevention Provisions'') as an applicable
requirement, together with conditions requiring the source owner or
operator to submit a compliance schedule for meeting all applicable
requirements of part 68, and requiring the source to include in its
annual compliance certification a statement certifying that the source
is in compliance with all requirements of part 68, including the
requirements for registration and submission of a risk management plan.
    In particular, 40 CFR part 68 requires sources that have more than
a threshold level of any regulated substance to prepare and submit an
RMP. See 40 CFR 68.12(a) and 68.150. Unless the source can certify in
the RMP that no member of the public would be affected by any
accidental release from the source, 40 CFR part 68 further requires
sources to implement a risk management system, to conduct a hazard
assessment, to implement a chemical accident prevention program, to
implement an emergency response program, and to include data on the
implementation of these programs in the RMP. See 40 CFR 68.12(b), (c),
and (d). All those requirements are included as applicable permit
conditions by effect of the State's listing 40 CFR 68.215(a) in all
Montana operating permits. As the Governor committed, Montana will
satisfy its obligations under section 112(r) of the Act by requiring
all part 70 sources to certify compliance with applicable risk
management planning requirements and by developing compliance schedules
for sources that have not yet submitted risk management plans to EPA.
When we referred to the State's commitment in the notice proposing full
approval, we should have clarified that the commitment came from the
Governor, thus assuring EPA that the State would meet its statutory
obligations.
    Comment 5: The commenter stated that the State's revised rule on
termination, revocation, and re-issuance of state permits still
improperly limits the state's authority to terminate or revoke permits.
    EPA Response: Section 502(b)(5)(D) of the Act requires that the
permitting authority must have adequate authority to ``terminate,
modify, or revoke and reissue permits for cause.'' The State's original
version of the pertinent regulation provided that the Department could
terminate, modify or revoke and reissue permits ``for continuing and
substantial violations.'' EPA advised that this provision did not give
adequate authority to the Department to terminate or alter permits for
other kinds of cause: for example, to correct a material mistake in the
permit or to respond to an EPA objection to a permit. Subsequently,
Montana revised its rule, ARM 17.8.1210(2)(a), to say that permits
could be terminated, modified, or revoked and reissued ``for cause.''
The State then added, ``Appropriate `cause' for permit termination is
noncompliance with permit terms or conditions that is continuing or
substantial in nature and scope.'' EPA regards this added language as
providing an example when a permit may be terminated in the context of
an enforcement action. The specific example with respect to permit
termination does not limit the State's general authority to terminate,
modify, or revoke and reissue any permit for cause. In addition, we
believe that the phrase ``continuing or substantial in nature and
scope'' in the specific example is not necessarily less inclusive than
the phrase ``continuing and substantial violations'' in the earlier
version. We believe that the State's revision of the regulation has
satisfied EPA's concern that the Department have adequate authority to
revise or terminate permits, whenever sufficient cause exists.

IV. Final Action

    In this document, EPA is granting full approval of the Montana part
70 operating permits program for all areas within the State except the
following: any sources of air pollution located in ``Indian Country''
as defined in 18 U.S.C. 1151, including the following Indian
reservations in the State: Northern Cheyenne, Rocky Boys, Blackfeet,
Crow, Flathead, Fort Belknap, and Fort Peck Indian Reservations, or any
other sources of air pollution over which an Indian Tribe has
jurisdiction. See section 301(d)(2)(B) of the Act; see also 63 FR 7254
(February 12, 1998). The term ``Indian Tribe'' is defined under the Act
as ``any Indian tribe, band, nation, or other organized group or
community, including any Alaska Native village, which is federally
recognized as eligible for the special programs and services provided
by the United States to Indians because of their status as Indians.''
See section 302(r) of the Act; see also 58 FR 54364 (Oct. 21, 1993).
    This rule will be effective January 22, 2001.

V. Administrative Requirements

A. Executive Order 12866

    The Office of Management and Budget has exempted this regulatory
action from Executive Order 12866, entitled ``Regulatory Planning and
Review.''

B. Executive Order 13132

    Federalism (64 FR 43255, August 10, 1999) revokes and replaces
Executive Order 12612 (Federalism) and Executive Order 12875 (Enhancing
the Intergovernmental Partnership). Executive Order 13132 requires EPA
to develop an accountable process to ensure ``meaningful and timely
input by state and local officials in the development of regulatory
policies that have federalism implications.'' ``Policies that have
federalism implications'' is defined in the Executive Order to include
regulations that have ``substantial direct effects on the states, on
the relationship between the national government and the states, or on
the distribution of power and responsibilities among the various levels
of government.'' Under Executive Order 13132, EPA may not issue a

[[Page 80789]]

regulation that has federalism implications, that imposes substantial
direct compliance costs, and that is not required by statute, unless
the Federal Government provides the funds necessary to pay the direct
compliance costs incurred by state and local governments, or EPA
consults with state and local officials early in the process of
developing the proposed regulation. EPA also may not issue a regulation
that has federalism implications and that preempts state law unless the
Agency consults with state and local officials early in the process of
developing the proposed regulation.
    This final rule will not have substantial direct effects on the
states, on the relationship between the national government and the
states, or on the distribution of power and responsibilities among the
various levels of government, as specified in Executive Order 13132.
Thus, the requirements of section 6 of the Executive Order do not apply
to this rule.

C. Executive Order 13045

    Protection of Children from Environmental Health Risks and Safety
Risks (62 FR 19885, April 23, 1997), applies to any rule that: (1) is
determined to be ``economically significant'' as defined under
Executive Order 12866, and (2) concerns an environmental health or
safety risk that EPA has reason to believe may have a disproportionate
effect on children. If the regulatory action meets both criteria, the
Agency must evaluate the environmental health or safety effects of the
planned rule on children, and explain why the planned regulation is
preferable to other potentially effective and reasonably feasible
alternatives considered by the Agency.
    This rule is not subject to Executive Order 13045 because it is not
an economically significant regulatory action as defined by Executive
Order 12866, and it does not establish a further health or risk-based
standard because it approves state rules which implement a previously
promulgated health or safety-based standard.

D. Executive Order 13084

    Under Executive Order 13084, EPA may not issue a regulation that is
not required by statute, that significantly or uniquely affects the
communities of Indian tribal governments, and that imposes substantial
direct compliance costs on those communities, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by the tribal governments, or EPA consults with those
governments. If EPA complies by consulting, Executive Order 13084
requires EPA to provide to the Office of Management and Budget, in a
separately identified section of the preamble to the rule, a
description of the extent of EPA's prior consultation with
representatives of affected tribal governments, a summary of the nature
of their concerns, and a statement supporting the need to issue the
regulation. In addition, Executive Order 13084 requires EPA to develop
an effective process permitting elected officials and other
representatives of Indian tribal governments ``to provide meaningful
and timely input in the development of regulatory policies on matters
that significantly or uniquely affect their communities.'' Today's rule
does not significantly or uniquely affect the communities of Indian
tribal governments. This action does not involve or impose any
requirements that affect Indian Tribes. Accordingly, the requirements
of section 3(b) of Executive Order 13084 do not apply to this rule.

E. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency
to conduct a regulatory flexibility analysis of any rule subject to
notice and comment rulemaking requirements unless the agency certifies
that the rule will not have a significant economic impact on a
substantial number of small entities. Small entities include small
businesses, small not-for-profit enterprises, and small governmental
jurisdictions.
    This final rule will not have a significant impact on a substantial
number of small entities because part 70 approvals under section 502 of
the Act do not create any new requirements but simply approve
requirements that the State is already imposing. Therefore, because
this approval does not create any new requirements, I certify that this
action will not have a significant economic impact on a substantial
number of small entities.

F. Unfunded Mandates

    Under section 202 of the Unfunded Mandates Reform Act of 1995
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA
must prepare a budgetary impact statement to accompany any proposed or
final rule that includes a Federal mandate that may result in estimated
costs to state, local, or tribal governments in the aggregate; or to
the private sector, of $100 million or more. Under section 205, EPA
must select the most cost-effective and least burdensome alternative
that achieves the objectives of the rule and is consistent with
statutory requirements. Section 203 requires EPA to establish a plan
for informing and advising any small governments that may be
significantly or uniquely impacted by the rule.
    EPA has determined that the approval action promulgated does not
include a Federal mandate that may result in estimated costs of $100
million or more to either state, local, or tribal governments in the
aggregate, or to the private sector. This Federal action approves pre-
existing requirements under State or local law, and imposes no new
requirements. Accordingly, no additional costs to State, local, or
tribal governments, or to the private sector, result from this action.

G. Submission to Congress and the Comptroller General

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of 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 the rule in the Federal Register. This rule is not a
``major rule'' as defined by 5 U.S.C. 804(2).

H. Petitions for Judicial Review

    Under section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by February 20, 2001. Filing a
petition for reconsideration by the Administrator of this final rule
does not affect the finality of this rule for the purposes of judicial
review nor does it extend the time within which a petition for judicial
review may be filed, and shall not postpone the effectiveness of such
rule or action. This action may not be challenged later in proceedings
to enforce its requirements. (See section 307(b)(2).)
