SUMMARY: EPA approves revisions to the State Implementation Plan (SIP) 
submitted by the Governor of North Dakota with a letter dated September 
28, 1998. The revisions affect air pollution control rules regarding 
general

[[Page 47396]]

provisions, the State SO2 ambient air quality standard, 
emissions of particulate matter and organic compounds, and permits to 
construct. EPA will handle separately the revisions to the Title V 
operating permit program, a direct delegation request for emission 
standards for hazardous air pollutants for source categories, and the 
State's plan for hospital, medical, and infectious waste incinerators.
    Finally, EPA is providing notice that on May 7, 1999, North Dakota 
was delegated authority to implement and enforce the New Source 
Performance Standards (NSPS) in 40 CFR part 60, as of November 1, 1997, 
(excluding subpart Eb).

DATES: This direct final rule is effective on November 1, 1999 without 
further notice, unless EPA receives adverse comment by September 30, 
1999. If adverse comment is received, EPA will publish a timely 
withdrawal of the direct final rule in the Federal Register informing 
the public that the rule will not take effect.

I. Background

    In response to a petition by the Lignite Energy Council, the North 
Dakota Legislature adopted Senate Bill No. 2356 in the spring of 1997. 
This bill created a new section in chapter 23-25 of the North Dakota 
Century Code which, among other things, prohibits the adoption of 
ambient air quality rules or standards for sulfur dioxide that affect 
coal conversion facilities or petroleum refineries that are more strict 
than federal rules or standards under the Clean Air Act. As a result, 
the North Dakota Department of Health revised Chapter 33-15-02, Ambient 
Air Quality Standards, of the North Dakota Administrative Code 
(N.D.A.C.), to, among other things, exempt coal conversion facilities 
and petroleum refineries from the North Dakota ambient air quality 
standards (AAQS) for sulfur dioxide (SO2), which are more 
stringent than the National Ambient Air Quality Standards (NAAQS) for 
SO2. The revision is considered a relaxation. Because of the 
change in State law, coal conversion facilities and petroleum 
refineries will no longer be limited by the North Dakota AAQS and will 
not be allowed to emit SO2 up to the NAAQs, unless limited 
by Prevention of Significant Deterioration (PSD) increment. The 
September 28, 1998 SIP revision addresses, among other things, this 
rule revision.

II. Analysis of State Submission

A. Procedural Background

    The Act requires States to follow certain procedures in developing 
implementation plans and plan revisions for submission to EPA. Sections 
110(a)(2) and 110(1) of the Act provide that each implementation plan a 
State submits must be adopted after reasonable notice and public 
hearing.
    We also must determine whether a submittal is complete and 
therefore warrants further review and action (see section 110(k)(1) of 
the Act and 57 FR 13565). EPA's completeness criteria for SIP 
submittals can be found in 40 CFR part 51 appendix V. EPA attempts to 
determine completeness within 60 days of receiving a submission. 
However, the law considers a submittal complete if we don't determine 
completeness within six months after we receive it.
    To provide for public comment, the North Dakota Department of 
Health (NDDOH), after providing adequate notice, held a public hearing 
on May 7, 1998 to address the revisions to the SIP and Air Pollution 
Control Rules. Following the public hearing, public comment period, and 
legal review by the North Dakota Attorney General's Office, the North 
Dakota State Health Council adopted the rule revisions, which became 
effective on September 1, 1998.
    The Governor of North Dakota submitted the SIP revisions to EPA 
with a letter dated September 28, 1998. We reviewed them to determine 
completeness under the completeness criteria in 40 CFR part 51, 
appendix V. We found the submittal complete and so notified the 
Governor in a letter dated December 3, 1998. That letter also described 
the next steps to be taken in our review.

B. September 28, 1998 Revisions

    As noted above, we will handle separately the revisions in the 
September 28, 1998 submittal regarding Chapter 33-15-14 (section 
specific to the Title V operating permit program), a direct delegation 
request for North Dakota Air Pollution Control Rules Chapter 33-15-22, 
regarding emission standards for hazardous air pollutants for source 
categories, as well as the State's plan for hospital, medical, and 
infectious waste incinerators. The submittal also included a direct 
delegation request for standards of performance for new stationary 
sources (see below). Finally, the submittal addressed revisions to 
general provisions, the State SO2 ambient air quality 
standard, emissions of particulate matter and organic compounds, and 
the permit to construct program, which involve the following chapters 
of the N.D.A.C. to be addressed in this document: 33-15-01 General 
Provisions; 33-15-02 Ambient Air Quality Standards; 33-15-05 Emissions 
of Particulate Matter Restricted; 33-15-07 Control of Organic Compound 
Emissions; and 33-15-14 Designated Air Contaminant Source, Permit to 
Construct, Minor Source Permit to Operate, Title V Permit to Operate 
(subsection specific to permit to construct only).
1. Chapter 33-15-01, N.D.A.C., General Provisions
    Definitions for ``coal conversion facility'' and ``petroleum 
refinery'' were added to this chapter. This chapter was also revised to 
update the definition of volatile organic compounds (``VOCs'') in 33-
15-01-04.51 to match the Federal definition as published by EPA on 
April 9, 1998 (63 FR 17331). These revisions are consistent with 
Federal requirements, and therefore, approvable.
2. Chapter 33-15-02, N.D.A.C., Ambient Air Quality Standards
    In section 33-15-02-07, Concentrations of Air Contaminants in the 
Ambient Air Restricted, two new subsections were added. The new 
subsection 3 allows coal conversion facilities and petroleum refineries 
to emit sulfur dioxide up to the National Ambient Air Quality Standards 
(NAAQS). This subsection also reiterates that affected facilities must 
still comply with the Prevention of

[[Page 47397]]

Significant Deterioration (PSD) increments. The new subsection 4 allows 
facilities that experience a malfunction, or that need to shut down air 
pollution control equipment for maintenance, to emit sulfur dioxide in 
quantities that may exceed the 1-hour and 24-hour State Ambient Air 
Quality Standards (AAQS), but not to exceed the NAAQS. These revisions 
are a relaxation of requirements for affected sources because the NAAQS 
are less stringent than the State standards.
    In addition, Table 2 was added to this chapter. Table 2 lists the 
NAAQS for sulfur dioxide.
    In a March 28, 1997 letter from Richard Long, EPA, to Dana Mount, 
North Dakota Department of Health (NDDOH), EPA requested more 
information from the State regarding the implementation of Senate Bill 
No. 2356, which had recently been adopted by the State legislature and 
signed by the Governor. This bill prohibits the NDDOH from adopting 
sulfur dioxide ambient air quality standards affecting coal conversion 
facilities or petroleum refineries that are more strict than federal 
standards. The bill also provides for retroactive application, thus 
affecting earlier permitting decisions by NDDOH. EPA requested 
information to support a demonstration that the NAAQS and PSD 
increments would be protected in light of this change in State 
standards. In a series of letters from the NDDOH dated April 10 and 
November 17, 1997, and March 23, June 10, and December 1, 1998, the 
State provided EPA with adequate technical support information to 
demonstrate that the NAAQS and PSD increments would be protected.
    a. State's Technical Support Information. According to NDDOH, 
Senate Bill No. 2356 allows existing and new coal conversion facilities 
and petroleum refineries to emit sulfur dioxide in amounts that could 
raise ambient concentrations up to the NAAQS. The sources would, 
however, have to comply with all other applicable requirements of the 
State Implementation Plan (SIP), including PSD increment. Note that the 
new law only applies to nine existing facilities (seven power plants, 
one coal gasification plant, and one petroleum refinery). For 
facilities that indicate a desire to increase their allowable emission 
rates based on this legislation, the State intends to review associated 
PSD increment consumption and NAAQS impacts. The State does not believe 
any increase in emissions from these facilities will endanger the NAAQS 
because air quality in North Dakota is good based on moniotring 
conducted around the State, and ambient SO2 levels are well 
below both the State AAQS and the NAAQS.
    At EPA's request, the State outlined how it intended to implement 
the requirements of SB2356 in a November 17, 1997 letter from William 
Delmore, North Dakota Assistant Attorney General, to Terry Lukas, EPA. 
The State provided a list of existing sources which are subject to 
Senate Bill No. 2356, a proposed rule amendment, and SIP revision 
schedule. The State proposed to revised two chapters of its Air 
Pollution Control Rules to implement SB2356, namely Chapters 33-15-01, 
General Provisions, and 33-15-02, Ambient Air Quality Standard. In 
Chapter 33-15-01, the NDDOH proposed definitions for ``coal conversion 
facility'' and ``petroleum refinery.'' In Chapter 33-15-02, the NDDOH 
proposed to include the substantive requirements of SB2356. The State 
also declared its intent to enforce compliance with these revisions.
    Upon review of Mr. Delmore's November 17, 1997 letter, EPA provided 
further guidance to the State regarding the necessary demonstration to 
show that the revisions would ensure protection of the NAAQS and PSD 
increments in light of the change in applicability of the State AAQS 
mandated by Senate Bill No. 2356. In a January 8, 1998 letter, EPA 
indicated that the requirement for making such a demonstration could 
not be fulfilled at the time of SIP revision because the effect of the 
relaxation on ambient air quality would depend on future permitting 
actions. Therefore, the demonstration would have to be built into the 
revised SIP so that EPA could consider approval of the revision.
    EPA provided wording changes to the proposed regulatory language to 
ensure that emissions would not be permitted in any manner or amount 
that would cause or contribute to a violation of the NAAQS or PSD 
increments and to require a demonstration through modeling, with 
opportunity for EPA review, that a revised emission limit would not 
cause or contribute to a violation of the NAAQS, PSD increments, or any 
other requirement under the Federal Clean Air Act.
    EPA also instructed the State to provide additional information as 
technical support documentation which would be necessary for EPA to 
consider approval of the final SIP revision, as follows:

--General modeling requirements that sources will have to meet if 
they seek to raise their emissions limits as a result of this change 
in applicability of the State AAQS. These general modeling 
requirements should follow the requirements contained in EPA's 
Guidedline on Air Quality Modeling (40 CFR part 51, appendix W) and 
should include consideration of cumulative impacts.
--An explanation of how the State intends to determine ``that any 
source * * * causes a verifiable ambient air quality standard 
violation which is attributable to the source * * * for compliance 
purposes, as indicated in Mr. Delmore's November 17, 1997 letter.

    In a March 23, 1998 letter, the NDDOH provided its draft SIP 
revision to EPA for review and comment prior to public hearing. This 
draft SIP revision included, among other things, the proposed 
regulatory revisions for implementing SB2356.
    With an April 29, 1998 comment letter for public hearing, EPA noted 
that, for the most part, our concerns about the proposed revisions as 
described in Mr. Delmore's November 17, 1997 letter had been addressed. 
The State addressed our suggested language changes by incorporating 
them into Chapter 33-15-02, Ambient Air Quality Standards, and Chapter 
33-15-14, Designated Air Contaminant Sources, Permit to Construct, 
Minor Source Permit to Operate, Title V Permit to Operate (subsection 
related to alterations to a source under the permit to construct 
section--see II.B.5. below). The State believed it was reasonable to 
address our concerns through Chapter 33-15-14 (as well as Chapter 33-
15-02) because any request for an increase in emissions will have to go 
through the State's permit process.
    EPA also requested additional information related to how to model 
different source categories subject to different SO2 
standards (State AAQS vs. NAAQS) in the same airshed, i.e., which 
standard would apply.
    In a June 10, 1998 letter from Dana Mount, NDDOH, to Richard Long, 
EPA, the State responded to our public hearing comments and provided 
some of the technical support documentation necessary. The State 
indicated that all modeling would be conducted in accordance with the 
``Guideline on Air Quality Models'' published by EPA. With respect to 
modeling different source categories subject to different 
SO2 standards in the same airshed, the State addressed the 
following scenarios:

    Existing source subject to State standard and new source subject 
to the NAAOS--A new source subject to the NAAQS will be permitted as 
long as modeling results indicate that the new source plus all 
existing sources do not cause or contribute to a violation of the 
NAAQS or PSD increments.

[[Page 47398]]

    Existing source subject to the NAAQS and a new source subject to 
the State standard--The new source will be permitted as long as it 
does not cause or contribute to a violation of the State AAQS or PSD 
increments. If modeling for this source plus all existing sources 
predicts a violation of the State standard or PSD increments, the 
new facility will not be permitted if it significantly contributes 
to these violations. If the new source would not significantly 
contribute to these violations, then it will be permitted. (However, 
a SIP revision will be required to address the predicted increment 
violation. See 40 CFR 51.166(a)(3).)
    Existing source subject to the NAAQS seeking to increase its 
emission limit in an air shed with existing sources subject to the 
State standard--The existing NAAQS source will be allowed to 
increase its emissions as long as the modeling (which includes all 
sources) does not predict a violation of the NAAQS or PSD 
increments.

    As the State's final piece of technical support documentation, a 
December 1, 1998 letter from Dana Mount, NDDOH, to Richard Long, EPA, 
summarized the State's approach to enforcement of its revised 
SO2 standard. In the event that data from the state-wide 
ambient air quality monitoring network indicates an exceedance of the 
SO2 standard, that data will be used along with dispersion 
modeling to determine what source or sources contributed to the 
exceedance. Both ambient monitoring and dispersion modeling will be 
used as the primary tools to determine corrective actions or 
enforcement activity. Dispersion modeling also will be used in the case 
of suspected exceedances to determine the necessity of establishing 
monitoring sites at locations of prime impact.
    b. EPA's Rationale for Approving Change. EPA believes that we can 
approve this change in applicability of more stringent State standards 
because the NAAQS, PSD increments, and other Clean Air Act programs 
appear to be protected, based on the information provided by the State 
in the letters discussed above and the State's incorporation of EPA's 
suggested regulatory language. The protective features of this SIP 
revision and the State's policy for implementing it are as follows:

    i. Demonstration is built into the SIP revision through 
regulatory language to ensure that the NAAQS, PSD increments, and 
other Clean Air Act requirements are protected. (See Chapter 33-15-
02-07. 3 and 4 and Chapter 33-15-14-02.3c)
    ii. Sources that seek to raise their emissions limits as a 
result of this change in applicability of the State AAQS will have 
to meet modeling requirements that follow EPA's Guideline on Air 
Quality Modeling (40 CFR part 51, appendix W) and will have to 
include consideration of cumulative impacts.
    iii. Both ambient monitoring and dispersion modeling will be 
used to determine corrective actions or enforcement activity in the 
event that monitoring data indicates an exceedance of the 
SO2 standard. Dispersion modeling also will be used in 
the case of suspected exceedances to determine the need for new 
monitoring sites at locations or prime impact.

    For a more detailed discussion of EPA's rationable for approving 
this revision, please refer to the Technical Support Document (TSD) 
accompanying this action.
3. Chapter 33-15-05, N.D.A.C., Emissions of Particulate Matter 
Restricted
    The State deleted its requirements for new infectious waste 
incinerators since the units will be covered by the requirements in 
Chapter 33-15-12, Subpart Ec, Standards of performance for hospital/
medical/infectious waste incinerators for which construction is 
commenced after June 20, 1996. This change was made to avoid 
duplication of Federal rules; however, the State considers it a 
relaxation of State rules.
    The State has been delegated authority to implement and enforce the 
Federal New Source Performance Standard (NSPS) for hospital/medical/
infectious waste incinerators (HMIWI) for which construction is 
commenced after June 20, 1996 (subpart Ec--see below), and also has 
received approval of its State Plan to implement the Emission 
Guidelines for existing HMIWI (see 64 FR 25831, May 13, 1999). Given 
that the State is implementing that NSPS and State Plan, any change in 
particulate matter emissions requirements for affected sources in North 
Dakota is of a de minimus nature. Thus, EPA believes the overall impact 
of this revision, if any, is minor, and therefore, approvable.
4. Chapter 33-15-07, N.D.A.C., Control of Organic Compounds Emissions
    This revision is an administrative correction to the ``Scope'' 
section to correct the reference to Chapter 1 of the rules. It is minor 
in nature and approvable.
5. Chapter 33-15-14, N.D.A.C., Designated Air Contaminant Sources, 
Permit To Construct, Minor Source Permit To Operate, Title V Permit To 
Operate (Revisions Specific to Permit To Construct Section)
    Subsection 33-15-14-02.3.c, regarding alterations to a source under 
the permit to construct section, was added to clarify that any owner or 
operator of a source who requests an increase in the source's sulfur 
dioxide emission rate pursuant to Chapter 33-15-02-07.3 (see II.B.2 
above) must demonstrate through a dispersion modeling analysis that the 
revised allowable emissions will not cause or contribute to a violation 
of the NAAQS, PSD increments, or any other Federal Clean Air Act 
requirements. The revision also provides for public and EPA review of 
such requests.
    This language was added at EPA's request to ensure that the NAAQS, 
PSD increments, or any other Federal Clean Air Act requirements would 
be protected in light of the change in applicability of the State 
SO2 AAQS, as discussed in section II.B.2 above. This 
revision is approvable.

C. Delegation of Authority for NSPS

    With the September 28, 1998 submittal, North Dakota requested 
delegation of authority for implementation and enforcement of the NSPS 
(40 CFR part 60, subpart Ec) for hospital/medical/infectious waste 
incinerators pursuant to section 111(c) of the Clean Air Act, 42 U.S.C. 
7411(c), as amended. On May 7, 1999, delegation was given with the 
following letter:

Ref: 8P-AR
Honorable Edward T. Schafer,
Goveror of North Dakota, State Capitol, Bismarck, North Dakota 
58505-0001.

Re: Delegation of Clean Air Act New Source Performance Standards

    Dear Governor Schafer: In a September 28, 1998, letter from you 
and an October 6, 1998, letter from Francis Schwindt, North Dakota 
Department of Health, the State of North Dakota requested delegation 
of authority for revisions to the New Source Performance Standards 
(NSPS), promulgated in Chapter 33-15-12 of the North Dakota 
Administrative Code. The State's NSPS regulations incorporate by 
reference the Federal NSPS in 40 CFR Part 60 as in effect on 
November 1, 1997, with the exception of subpart Eb, which the State 
has not adopted. In the above-mentioned letters, the State requests 
authority for implementation and enforcement of the NSPS through the 
delegation of authority process pursuant to section 111(c) of the 
Clean Air Act, 42 U.S.C. Sec. 7411(c), as amended.
    Subsequent to States adopting NSPS regulations, EPA delegates 
the authority for the implementation and enforcement of those 
standards, so long as the State's regulations are not less stringent 
than the Federal regulations. EPA has reviewed the pertinent 
statutes and regulations of the State of North Dakota and has 
determined that they provide an adequate and effective procedure for 
the implementation and enforcement of the NSPS by the State of North 
Dakota. Therefore, pursuant to Section 111(c) of the Clean Air Act 
(Act), as amended, and 40 CFR Part 60, EPA hereby delegates its 
authority for the implementation and enforcement of one NSPS to the 
State of North Dakota as follows:
    (A) Responsibility for all sources located, or to be located, in 
the State of North Dakota

[[Page 47399]]

subject to the standards of performance for new stationary sources 
promulgated in 40 CFR Part 60 as in effect on November 1, 1997, with 
the exception of subpart Eb, which the State has not adopted. The 
additional category of new stationary sources covered by this 
delegation is hospital/medical/infectious waste incinerators for 
which construction is commenced after June 20, 1996 (subpart Ec).
    (B) Not all authorities of NSPS can be delegated to states under 
Section 111(c) of the Act, as amended. The EPA Administrator retains 
authority to implement those sections of the NSPS that require: (1) 
approving equivalency determinations and alternative test methods, 
(2) decision making to ensure national consistency, and (3) EPA 
rulemaking to implement. Therefore, in delegating to North Dakota 
the implementation and enforcement authority for Subpart Ec, the 
following authorities shall be retained by the EPA Administrator and 
not transferred to the State: (1) the requirements of Sec. 60.56c(i) 
establishing operating parameters when using controls other than 
those listed in Sec. 60.56c(d); and (2) alternative methods of 
demonstrating compliance under Sec. 60.8. For the other NSPS 
categories previously delegated to the State, our May 28, 1998, 
delegation letter lists those sections which can't be delegated to 
the State.
    (C) As 40 CFR Part 60 is updated, North Dakota should revise its 
regulations accordingly and in a timely manner and submit to EPA 
requests for updates to its delegated authority.
    This delegation is based upon and is a continuation of the 
conditions stated in EPA's original delegation letter of August 30, 
1976, to the Honorable Arthur A. Link, then Governor of North 
Dakota, except that condition 5, relating to Federal facilities, has 
been voided by the Clean Air Act Amendments of 1977. It is also 
important to note that EPA retains concurrent enforcement authority, 
as stated in condition 2. In addition, if at any time there is a 
conflict between a State and a Federal NSPS regulation, the Federal 
regulation must be applied if it is more stringent than that of the 
State, as stated in condition 7. A copy of the August 30, 1976, 
letter was published in the notices section of the Federal Register 
on October 13, 1976 (41 FR 44884), along with the associated 
rulemaking notifying the public that certain reports and 
applications required from operators of new and modified sources 
shall be submitted to the State of North Dakota (41 FR 44859). 
Copies of the Federal Register notices are enclosed for your 
convenience.
    Since this delegation is effective immediately, there is no need 
for the State to notify the EPA of its acceptance. Unless we receive 
written notice of objection from you within ten days of the date on 
which you receive this letter, the State of North Dakota will be 
deemed to have accepted all the terms of this delegation. An 
information notice will be published in the Federal Register in the 
near future informing the public of this delegation, in which this 
letter will appear in its entirety.
    If you have any questions on this matter, please call me, or 
have your staff contact Richard Long, Director of our Air and 
Radiation Program, at 303-312-6005.

      Sincerely yours,
William P. Yellowtail,
Regional Administrator.

III. Final Action

    EPA is approving North Dakota's SIP revision, as submitted by the 
Governor with a letter dated September 28, 1998. The revisions in the 
September 28, 1998 submittal which are being approved in this document 
involve the following chapters of the North Dakota Administrative Code: 
33-15-01 General Provisions; 33-15-02 Ambient Air Quality Standards; 
33-15-05 Emissions of Particulate Matter Restricted; 33-15-07 Control 
of Organic Compounds Emissions; and 33-15-14 Designated Air Contaminant 
Sources, Permit to Construct, Minor Source Permit to Operate, Title V 
Permit to Operate (revisions specific to the Permit to Construct 
program only).
    In addition, the September 28, 1998 submittal included revisions to 
Chapter 33-15-14, N.D.A.C., Designated Air Contaminant Sources, Permit 
to Construct, Minor Source Permit to Operate, Title V Permit to Operate 
(section specific to Title V Permit to Operate program), the State's 
111(d) plan for existing hospital/medical/infectious waste 
incinerators, and a request for direct delegation of Chapter 33-15-22, 
N.D.A.C., Emission Standards for Hazardous Air Pollutants for Source 
Categories, all of which are being handled separately.
    Finally, as requested by the State with its September 28, 1998 
submittal, EPA is providing notice that it granted delegation of 
authority to North Dakota on May 7, 1999, to implement and enforce the 
NSPS promulgated in 40 CFR part 60, promulgated as of November 1, 1997 
(except subpart Eb, which the State has not adopted). However, the 
State's NSPS authorities do not include those authorities which cannot 
be delegated to the states, as defined in 40 CFR part 60.
    EPA is publishing this rule without prior proposal because the 
Agency views this as a noncontroversial amendment and anticipates no 
adverse comments. The State requested this action. However, in the 
``Proposed Rules'' section of today's Federal Register publication, EPA 
is publishing a separate document that will serve as the proposal to 
approve the SIP revision if adverse comments should be filed. This rule 
will be effective November 1, 1999 without further notice unless the 
Agency receives adverse comments by September 30, 1999. If the EPA 
receives adverse comments, EPA will publish a timely withdrawal in the 
Federal Register informing the public that the rule will not take 
effect. EPA will address all public comments in a subsequent final rule 
based on the proposed rule. The EPA will not institute a second comment 
period on this action. Any parties interested in commenting must do so 
at this time.

IV. Administrative Requirements

A. Executive Order 12866

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

B. Executive Order 12875

Executive Order 12875: Enhancing the Intergovernmental Partnership
    Under Executive Order 12875, EPA may not issue a regulation that is 
not required by statute and that creates a mandate upon a state, local, 
or tribal government, unless the Federal Government provides the funds 
necessary to pay the direct compliance costs incurred by those 
governments, or EPA consults with those governments. If EPA complies by 
consulting, Executive Order 12875 requires EPA to provide to the Office 
of Management and Budget a description of the extent of EPA's prior 
consultation with representatives of affected state, local, and tribal 
governments, the nature of their concerns, copies of any written 
communications from the governments, and a statement supporting the 
need to issue the regulation. In addition, Executive Order 12875 
requires EPA to develop an effective process permitting elected 
officials and other representatives of state, local, and tribal 
governments ``to provide meaningful and timely input in the development 
of regulatory proposals containing significant unfunded mandates.''
    Today's rule does not create a mandate on State, local or tribal 
governments. The rules does not impose any enforceable duties on these 
entities. This rule has the effect of making existing, state-
enforceable requirements federally enforceable. Accordingly, the 
requirements of section 1(a) of Executive Order 12875 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),

[[Page 47400]]

applies to any rule that: (1) Is determined to be ``economically 
significant'' as defined under E.O. 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.
    EPA interprets E.O. 13045 as applying only to those regulatory 
actions that are based on health or safety risks, such that the 
analysis required under section 5-501 of the Order has the potential to 
influence the regulation. This rule is not subject to E.O. 13045 
because it approves a state rule implementing a Federal standard.

D. Executive Order 13084

Executive Order 13084: Consultation with Coordination With Indian 
Tribal Governments
    Under E.O. 13084, EPA may not issue a regulation that is not 
required by statute, that significantly affects 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 rule does not create a 
mandate on tribal governments. 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 SIP approvals under 
section 110 and subchapter I, part D of the Clean Air Act do not create 
any new requirements but simply approve requirements that the State is 
already imposing. Therefore, because the Federal SIP approval does not 
create any new requirements, I certify that this action will not have 
significant economic impact on a substantial number of small entities. 
Moreover, due to the nature of the Federal-State relationship under the 
Clean Air Act, preparation of a flexibility analysis would constitute 
Federal inquiry into the economic reasonableness of state action. The 
Clean Air Act forbids EPA to base its actions concerning SIPs on such 
grounds. Union Electric Co. v. U.S. E.P.A., 427 U.S. 246, 256-66 
(1976); 42 U.S.C. 7410(a)(2).

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 November 1, 1999. 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).)
