SUPPLEMENTARY INFORMATION:

I. Background

    On July 1, 1987 (52 FR 24634), EPA revised the national ambient air 
quality standards (NAAQS) for particulate matter. Total suspended 
particulate (TSP) was replaced as the indicator for particulate matter 
ambient standard by a new indicator, particulate matter with a nominal 
aerodynamic diameter of 10 micrometers or less in size (PM-10). In 
response, ADEC amended its rules and regulations which dealt with 
particulate matter to assure compliance with particulate NAAQS 
throughout Alaska, and in addition, adopted numerous other changes, 
including amendments to its regulations for new source review. The 
package, dated October 15, 1991, was received by EPA on October 21, 
1991, together with the proof of filing certification by the Lieutenant 
Governor of Alaska and a certified copy of the regulations dealing with 
Air Quality Control, 18 AAC 50, for inclusion into the SIP.
    An earlier package, submitted on July 17, 1990, requested EPA to 
address out-of-date sections in the CFR and included Alaska statutes 
which were applicable to the corrections.
    On March 24, 1994 further amendments to 18 AAC 50, including 
amendments to the State Air Quality Control Plan (which is incorporated 
by reference in 18 AAC 50), were submitted to EPA as a revision to the 
Alaska SIP. These amendments include further changes to the regulations 
for PM-10 and new source review.

II. Description of Revisions

A. Amendments to Air Quality Control Plan, October 15, 1991

    The October 15, 1991 submittal encompasses a broad range of topics. 
Specifically, the amendments to 18 AAC 50:
    1. establish an ambient air quality standard for particulate matter 
smaller than 10 microns;
    2. revise the provisions relating to wood-fired heating devices in 
the Juneau Mendenhall Valley;
    3. establish air quality increments for oxides of nitrogen;
    4. reduce the visible emission standard for marine vessels from 40 
percent to 20 percent opacity;
    5. change the incinerator permit size threshold from 1000 lb/hr 
charging rate for an individual incinerator to 1000 lb/hr on the basis 
of facility-wide capacity;
    6. establish a permit program that will allow new and modified 
major carbon monoxide-emitting facilities to be constructed in 
Anchorage and Fairbanks without disrupting progress towards attaining 
compliance with the ambient air quality standards for carbon monoxide;
    7. establish a new air episode category called ``air quality 
advisory'';
    8. restrict wood stove operation during an air quality advisory and 
an air emergency;
    9. require a public notice and 30-day public comment period for all 
new Air Quality Control Permits issued under 18 AAC 50.
    10. specify minimum requirements on quality assurance and quality 
control for ambient monitoring programs; and
    11. clarify certain permit requirements and procedures, especially 
issues pertaining to the definition and application of ``actual'' and 
``allowable'' emissions.
    EPA approves the following amendments to 18 AAC 50, Air Quality 
Control Regulations, from the submission by ADEC dated October 15, 1991 
for inclusion into the Alaska SIP.

Article 1. Program Standards and Limitations

    Sections 020(a)(1) and 020(b), Ambient Air Quality Standards, are 
revised to establish State ambient air quality standards and Prevention 
of Significant Deterioration increments which are as stringent as the 
Federal standards.
    Section 085, Wood-fired heating devices, is revised to establish 
elements of the PM-10 control strategy which meet the criteria set 
forth by EPA to assure attainment and maintenance of the PM-10 NAAQS.
    Section 100, Marine vessels, is revised to establish lower emission 
standards that apply to all marine vessels within three miles of the 
coastline of Alaska in order to reduce visibility problems encountered 
in Alaska that are associated with marine vessels.

Article 2. Permit Requirements

    Section 300(a)(3) is amended to require permits for incinerators 
having a total combined rated capacity of 1,000 pounds per hour or 
more.
    Section 300(a)(5), (6) and (8), Permit to Operate, are revised by 
making numerous editorial changes for clarity.
    Section 300(a)(7), Permit to Operate, is revised by adding a 
requirement for a permit to operate for facilities that provide 
emission offsets.
    Section 300(a)(9), Permit to Operate, is revised by adding a new 
provision which requires a permit to operate for facilities located 
within ten kilometers of a nonattainment area, which have been 
installed or modified after the [[Page 8945]] effective date of the 
regulation change and have an allowable emission increase of 100 tons 
per year of the nonattainment air contaminant.
    Section 300(d), Permit to Operate, is revised by changing the 
requirements for new and modified major sources in nonattainment areas 
to require emission offsets in lieu of using a growth allowance.
    Sections 300(e) and 300(g), Permit to Operate, are revised by 
making a number of editorial changes for clarity.
    Section 300, Permit to Operate, is revised by adding a new 
paragraph (h) which sets the requirements for sources required to have 
a permit under the new Section 300(a)(9).

Article 3. Permit Review Criteria

    Section 400(a), Application Review and Issuance of Permit to 
Operate, is revised to require public notice of all applications of 
facilities requiring a new Air Quality Control Permit to Operate and 
for certain renewals.
    Sections 400 (b), (c), and (d), Application Review and Issuance of 
Permit to Operate, are revised by making a number of editorial changes 
for clarity.
    Section 400(c), Application Review and Issuance of Permit to 
Operate, is revised by adding provisions for emission offsets in lieu 
of an emissions allowance for new or modified major sources located in 
a nonattainment area.

Article 4. Regulation Compliance Criteria

    Section 510, Ambient Analysis Methods, is revised to clarify the 
approved ambient monitoring procedures and quality assurance 
requirements.
    Section 520, Air Quality Monitoring, is revised by making several 
editorial changes.

Article 5. Procedure and Administration

    Section 610, Air Episodes and Advisories, is revised by changing 
the indicator for particulate matter from TSP to PM-10, lowering the 
concentrations for declaring an air alert, warning, or emergency, and 
adding a provision allowing ADEC to declare an air advisory and to 
request voluntary emission curtailments from operators of air 
contaminant sources.
    Section 620, Air Quality Control Plan, is revised to reflect the 
date for new revisions to Volumes II and III of the Air Quality Control 
Plan.

Article 6. General Provisions

    Section 900, Definitions, is amended by revising the current 
definitions of the terms ``actual emissions,'' ``baseline 
concentration,'' ``baseline date,'' ``regulated air pollutant,'' ``wood 
smoke control area,'' and ``fugitive emissions,'' and adding new 
definitions of the terms ``approved,'' ``nonattainment air 
contaminant,'' ``particulate matter emissions,'' ``PM-10,'' ``PM-10 
emissions,'' and ``total suspended particulate matter.''
    The above amendments to regulations and the State Air Quality 
Control Plan comply with EPA's regulations for control strategies to 
attain and maintain the NAAQS for particulate matter and for permits to 
construct pursuant to Parts C and D of the Act.

B. Amendments To Delete Obsolete Code of Federal Regulations (CFR) 
Sections

    In an earlier package submitted to EPA on July 17, 1990, ADEC 
submitted a request to correct findings of Alaska's SIP deficiency in 
40 CFR 52, Sections 52.73-96. ADEC identified and explained why several 
of those sections were now obsolete (dating back to 1973) and how they 
had been remedied by changes to Alaska's statutes and regulations. ADEC 
also submitted the applicable Alaska statutes (Title 46. Water, Air, 
Energy, and Environmental Conservation) to support their request for 
corrections. The sections are all identified below. At this time, EPA 
is making the following changes:
    Section 52.74(a)(1), Cook Inlet. Delete. The Cook Inlet Air 
Resources Management District has not existed for over a decade. 
Deficiencies related to permitting authority attributed to Cook Inlet 
Air Resources Management District do not exist.
    Section 52.74(a)(2), Fairbanks North Star Borough (FNSB). Delete. 
The Memorandum of Understanding between ADEC and FNSB gives the borough 
responsibility only for permitting open burns of less than 40 acres; 
monitoring and air quality forecasting; attainment planning; and motor 
vehicle inspection and maintenance. It does not include 
responsibilities for recordkeeping, monitoring requirements, and public 
availability of stationary source data. Therefore, deficiency findings 
in those areas are moot.
    Regarding emergency abatement, the CFR refers to Ordinance 
45.05.100, which is found to be deficient because it only refers to 
generalized conditions of air pollution. FNSB Ordinance 8.05.010-050, 
which gives the borough adequate authority, was accepted into the SIP 
in the May 26, 1989 Federal Register. FNSB Ordinance 8.04.071 provides 
adequate authority for injunctions. Therefore, Sec. 52.74(a)(2)(i) on 
injunctions, and (v) on episode abatement may be deleted.
    Section 52.74(a)(2)(vi), Legal Authority. Delete. The Fairbanks 
Inspection and Maintenance Program was accepted as fulfilling the 
transportation control requirement.
    Section 52.74(b), Legal Authority. Delete. This finding of 
deficiency for lack of authority to prevent operation or construction 
which may result in violation of ambient air quality standards is 
satisfied by 18 AAC 50.300 and 18 AAC 50.400. These sections define 
criteria for permit issuance, and prevent operation or construction 
without a permit.
    Section 52.74(c), Legal Authority. Delete. This subsection 
disapproves Alaska Statute (AS) 46.03.180 for not meeting the 
requirement for disclosure of emissions data. However, AS 46.03.180 
allows confidentiality only for some ``Records and Information, other 
than emission data.'' Therefore, the legal authority to provide for 
public availability of emission data is adequate, and this deficiency 
determination may be deleted.
    Section 52.73 (a) and (b), General Requirements. Delete. These are 
simply remedies to the deficiencies identified above in Sec. 52.74 and, 
since the legal authority to provide for public availability of 
emission data is adequate, these remedies may be deleted.
    Section 52.78, Review of new sources and modifications. EPA defers 
action on this section, which establishes a plan for review of new or 
modified indirect sources, to a later date when a subsequent Federal 
Register action will address the revisions to the Carbon Monoxide SIP 
submitted March 24, 1994 by ADEC.
    Section 52.80, Intergovernmental cooperation. Delete. This 
subsection refers to lack of clear delineation of responsibilities 
between state and local agencies. This has been addressed in memoranda 
of understanding between ADEC and the municipalities of Anchorage and 
Fairbanks which define responsibilities. In addition, emergency 
avoidance plans are described in the Alaska State Air Quality Control 
Plan.
    Section 52.81, Attainment dates for national standards, and
    Section 52.82, Extensions. No action to be taken at this time. The 
information contained in these two sections, pertaining to historical 
attainment dates and status data, will be updated at a later 
time. [[Page 8946]] 
    Section 52.84, Compliance schedules. Delete. All compliance 
schedules listed here are outdated. Compliance schedules have been 
replaced by compliance orders, which are enforcement actions, and are 
not part of the SIP.
    Section 52.95, Maintenance of national standards. Delete. These 
pre-1977 requirements are out of date and no longer applicable.
    Section 52.96(b), Significant deterioration of air quality. Retain. 
The State of Alaska does not have jurisdiction over Indian 
reservations. Therefore, EPA must retain this provision in the Code of 
Federal Regulations in order to promulgate Federal procedures to 
prevent significant deterioration of air quality in Indian reservations 
as part of the Alaska SIP.

C. Additional Amendments to the Air Quality Control Plan, March 24, 
1994

    The March 24, 1994 ADEC submittal of revisions for inclusion into 
the Alaska SIP include additional amendments to 18 AAC 50, Air Quality 
Control Plan. In some instances the amendments further revise the 
amendments dated October 15, 1991, and in those cases, EPA is approving 
the version of the rules as it exists under the most recent revision. 
The amendments EPA is specifically approving at this time from the 
March 24, 1994 submittal concern state air quality classifications for 
PM-10 and new source review requirements. All other amendments to the 
SIP contained in the March 24, 1994 submittal will be addressed in 
subsequent actions. At this time, EPA is approving the following 
amendments to 18 AAC 50, Air Quality Control:

Article 1. Program Standards and Limitations

    Section 021, State Air Quality Classifications, is revised by 
adding the Eagle River Community and Mendenhall Valley of Juneau as 
nonattainment areas for PM-10.

Article 2. Permit Requirements

    Section 300 (a)(7) and (a)(8), Permit to Operate, are revised by 
adding provisions to require a permit for sources located in PM-10 
nonattainment areas.
    Section 300(d), Permit to Operate, is revised to clarify that 
emission offsets must be enforceable at the time of permit issuance and 
that they must actually occur by the time that increased emissions from 
the new or modified source will occur. In addition, this section 
requires a demonstration that the benefits of construction, operation, 
or modification of the facility will significantly outweigh the 
environmental and social costs incurred due to its location in a 
nonattainment area.
    Sections 300 (e) and (g), Permit to Operate, are revised by making 
a number of editorial changes for clarity.

Article 3. Permit Review Criteria

    Section 400(a)(1)(A), Application Review and Issuance of Permit to 
Operate, is revised by making several editorial changes for clarity.
    Section 400(c)(3)(B)(ii), Application Review and Issuance of Permit 
to Operate, is revised by adding significance levels for PM-10.
    Section 400(c)(4), Application Review and Issuance of Permit to 
Operate, is revised to clarify that emission offsets must be 
enforceable at the time of permit issuance and that they must actually 
occur by the time that increased emissions from the new or modified 
source will occur. In addition, this section requires a demonstration 
that the benefits of construction, operation, or modification of the 
facility will significantly outweigh the environmental and social costs 
incurred due to its location in a nonattainment area.
    Section 400(d)(4), Application Review and Issuance of Permit to 
Operate, is revised by making several editorial changes for clarity.

Article 5. Procedure and Administration

    Section 620, State Air Quality Control Plan, is revised to reflect 
the date for new revisions to Volumes II and III of the Air Quality 
Control Plan.
    The above amendments include updates to air quality area 
classifications and reflect date changes to include the most recent 
(March 24, 1994) SIP revisions submitted from ADEC to EPA. Also, 
included are revisions of the new source review provisions to meet the 
new requirements of Part D of the Clean Air Act for moderate carbon 
monoxide and particulate matter nonattainment areas as set forth in the 
General Preamble for the Implementation of Title I of the Clean Air 
Act.

III. Summary of EPA Action

    In this action, EPA approves the following amendments to Alaska 
Administrative Code, 18 AAC 50, Air Quality Control Regulations, for 
inclusion into the Alaska SIP:
    A. Revisions to Article 1: In section 050.020, paragraphs (a)(1) 
and (b), section 085, and section 100;

IV. Administrative Review

    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA 
must prepare a regulatory flexibility analysis assessing the impact of 
any proposed or final rule on small entities. 5 U.S.C. 603 and 604. 
Alternatively, EPA may certify that the rule will not have a 
significant impact on a substantial number of small entities. Small 
entities include small businesses, small not-for-profit enterprises, 
and government entities with jurisdiction over populations of less than 
50,000.
    SIP approvals under section 110 and subchapter I, Part D of the CAA 
do not create any new requirements, but simply approve requirements 
that the state is already imposing. Therefore, because the federal SIP-
approval does not impose any new requirements, I certify that it does 
not have a significant impact on any small entities affected. Moreover, 
due to the nature of the federal-state relationship under the CAA, 
preparation of a regulatory flexibility analysis would constitute 
federal inquiry into the economic reasonableness of state action. The 
CAA 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 (S.Ct. 1976); 42 
U.S.C. 7410(a)(2).
    The EPA is publishing this action without prior proposal because 
the Agency views this as a noncontroversial amendment and anticipates 
no adverse comments. However, in a separate document in this Federal 
Register publication, the EPA is proposing to approve the SIP revision 
should adverse or critical comments be filed. This action will be 
effective April 17, 1995 unless, by March 20, 1995, adverse or critical 
comments are received.
    If the EPA receives such comments, this action will be withdrawn 
before the effective date by publishing a subsequent notice that will 
withdraw the final action. All public comments received will be 
addressed in a subsequent final rule based on this action serving as a 
proposed rule. The EPA will not institute a second comment period on 
this action. Any parties interested in commenting on this action should 
do so at this time. If no such comments are received, the public is 
advised that this action will be effective April 17, 1995.
    The EPA has reviewed this request for revision of the federally-
approved SIP for conformance with the provisions of the 1990 Clean Air 
Act Amendments enacted on November 15, 1990. The EPA has determined 
that this action conforms with those requirements.
    Nothing in this action should be construed as permitting or 
allowing or establishing a precedent for any future request for 
revision to any SIP. Each request for revision to the SIP shall be 
considered separately in light of specific technical, economic and 
environmental factors and in relation to relevant statutory and 
regulatory requirements.
    This action has been classified as a Table 2 action by the Regional 
Administrator under the procedures published in the Federal Register on 
January 19, 1989 (54 FR 2214-2225), as revised by an October 4, 1993 
memorandum from Michael H. Shapiro, Acting Assistant Administrator for 
Air and Radiation. The OMB has exempted this regulatory action from 
E.O. 12866 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 April 17, 1995. 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), 42 U.S.C. 
7607(b)(2).
