[Docket: EPA-R10-OAR-2011-0916; FRL-9910-43-Region 10]


Approval and Promulgation of Implementation Plans; Alaska

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is proposing to approve revisions to the Alaska State 
Implementation Plan (SIP). Alaska submitted these revisions on February 
13, 2008, December 11, 2009, April 14, 2010, November 29, 2010, October 
21, 2011, December 10, 2012, and January 28, 2013, to meet Clean Air 
Act (CAA) requirements. These revisions update the Alaska SIP to 
reflect changes to the National Ambient Air Quality Standards (NAAQS), 
area designations, and Federal permitting requirements. In addition, 
the submitted changes revise and clarify Alaska permitting rules, and 
remove provisions that are duplicated in other regulations. Although 
the EPA is proposing to approve most of the submitted revisions, the 
EPA is proposing to not approve certain provisions which are 
inappropriate for SIP approval. The EPA is also removing specific 
provisions from the Alaska SIP that were previously approved, but that 
implement other provisions of the CAA and that the State has not relied 
on to demonstrate attainment or maintenance of the NAAQS or to meet 
other specific requirements of section 110 of the CAA, and therefore 
should not be part of the Federally-approved Alaska SIP. Finally, the 
EPA is deferring action on certain portions of the submissions, 
including those that adopt by reference updates to the Federal 
nonattainment major new source review requirements, because those 
revisions will be addressed in a separate action.

DATES: Comments must be received on or before June 4, 2014.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R10-

I. Background

    The EPA last approved major revisions to the State of Alaska air 
quality regulations at Alaska Administrative Code Title 18 
Environmental Conservation, Chapter 50 Air Quality Control (18 AAC 50) 
on August 14, 2007 (72 FR 45378) (``2007 action''). More recently, the 
Alaska Department of Environmental Conservation (ADEC) submitted rule 
revisions to the EPA on February 13, 2008, December 11, 2009, April 14, 
2010, November 29, 2010, October 21, 2011, December 10, 2012, and 
January 28, 2013. These submissions include revisions to update the 
Alaska SIP for changes to the NAAQS, area designations, and Federal 
permitting requirements, in addition to changes and clarifications to 
Alaska permitting rules, and removal of provisions that are duplicated 
in other regulations.
    In this action, we are proposing to approve the rule changes 
submitted by Alaska, with certain exceptions described below. We are 
also removing specific provisions from the Alaska SIP that were 
previously approved by the EPA, but implement other requirements of the 
CAA and that the State has not relied on to demonstrate attainment or 
maintenance of the NAAQS or to meet other specific requirements of 
section 110 of the CAA, and therefore should not be part of the 
Federally-approved Alaska SIP. In addition, we are deferring action on 
certain portions of the submissions, including those adopting by 
reference updates to the Federal nonattainment major new source review 
(nonattainment NSR) permitting requirements at 40 CFR 51.165, as 
discussed in paragraph F below. We intend to address them in a separate 
action.
    Below is a summary of our evaluation of the submitted revisions to 
the Alaska SIP. For a more detailed discussion of the revisions, our 
analysis and proposed action, please see the technical support document 
(TSD) in the docket for this action. Please note that this action does 
not address portions of these Alaska submissions which we previously 
approved on February 9, 2011 (76 FR 7116), October 22, 2012 (77 FR 
64425), February 14, 2013 (78 FR 10546), and May 9, 2013 (78 FR 27071). 
In addition, our analysis in this proposed action discusses only the 
most recently submitted amendment to any particular provision. We 
describe how the submitted Alaska rules differ from the Federally-
approved Alaska SIP, and why the EPA believes the changes are 
approvable.

II. Evaluation of Submittals

A. Ambient Air Quality Standards

    The revisions submitted by Alaska update the State's ambient air 
quality standards at 18 AAC 50.010 ``Ambient Air Quality Standards'' to 
reflect the 2006 fine particulate matter (PM2.5), 2008 lead 
(Pb), 2010 sulfur dioxide (SO2), and 2010 nitrogen dioxide 
(NO2) NAAQS.\1\ Because the submitted revisions are 
consistent with the Federal NAAQS promulgated under the CAA, we are 
proposing to approve 18 AAC 50.010 ``Ambient Air Quality Standards,'' 
except paragraphs (7) and (8), which set State ambient air quality 
standards for reduced sulfur compounds and ammonia respectively. 
Consistent with our 2007 action, we are proposing to not approve 
paragraphs (7) and (8) because they establish State ambient air quality 
standards for reduced sulfur compounds and ammonia, and they are not 
NAAQS established under section 109 of the CAA (72 FR 45378).
---------------------------------------------------------------------------

    \1\ We note that on October 22, 2012, we approved the State's 
revision to this rule to align Alaska's ozone ambient air quality 
standard with the 2008 ozone NAAQS (77 FR 64425).
---------------------------------------------------------------------------

B. Air Quality Designations, Classifications and Control Regions

    The submitted revisions add subparagraph (b)(3) to 18 AAC 50.015 
``Air Quality Designations, Classification and Control Regions'' to 
identify the PM2.5 nonattainment area for the Fairbanks and 
North Pole urban area, in addition to an editor's note to clarify that 
nonattainment and maintenance areas, air quality control regions, and 
the Class I area boundaries can be found in the Alaska Air Quality 
Control Plan and 40 CFR Part 81. We are proposing to approve these 
revisions, which update the Alaska SIP to include the most recently 
designated nonattainment area in Alaska.

C. Baseline Dates and Maximum Allowable Increases

    The submissions revise 18 AAC 50.020 ``Baseline Dates and Maximum 
Allowable Increases'' to clarify minor source baseline dates and 
maximum allowable increases, including adding PM2.5 to the 
tables in the rule. Specifically, the revisions clarify that baseline 
dates will be determined using the already-established Federal 
definition for minor source baseline dates, that concentrations above 
the ambient air quality standard are prohibited, and that baseline 
concentrations will be determined using already-established Federal 
provisions. The submitted revisions are consistent with the CAA and 
implementing provisions in 40 CFR part 52 and 81 and therefore we are 
proposing to approve the revisions.

D. State Air Quality Control Plan

    As a matter of State law, 18 AAC 50.030 ``State Air Quality Control 
Plan'' adopts by reference Volumes II and III of the State Air Quality 
Control Plan and other documents. The submissions addressed in this 
action revise the appendices to the Air Quality Control Program (Volume 
III, 18 AAC 50 Air Quality Control) by amending 18 AAC 50.030. We are 
proposing to not approve the submitted revisions to 18 AAC 50.030 
because the referenced documents that form the basis for the 
submissions are being individually approved in this action. We are only 
proposing to approve those provisions specifically identified in the 
submissions and addressed in this action. The EPA takes action 
directly, as appropriate, on the specific provisions in the State Air 
Quality Control Plan that have been submitted by Alaska, so it is 
unnecessary for the EPA to approve 18 AAC 50.030.

E. Documents, Procedures and Methods Adopted by Reference

    18 AAC 50.035 ``Documents, Procedures, and Methods Adopted by 
Reference'' adopts by reference the Alaska in situ burning guidelines, 
various Federal monitoring and modeling requirements and guidance, 
State ``Title V Application Forms,'' Federal reference and 
interpretation methods, and standard test methods. Except for the 
adoption by reference of the State ``Title V Standard Application and 
Forms,'' we are proposing to approve the submitted revisions to this 
provision because the changes update the Alaska SIP for the latest 
versions of specific documents, and add several new Federal reference 
and interpretation methods required to implement revised NAAQS. The 
State ``Title V Standard Application and Forms'' are inappropriate for 
SIP approval because they are not a requirement under section 110 of 
title I of the CAA, but rather are a requirement of title V of the CAA.
    We note that, consistent with our 2007 action, we are proposing to 
not approve 18 AAC 50.035(b)(4), which specifies test methods related 
to 40 CFR part 63 (72 FR 45378). This provision is inappropriate for 
SIP approval because it relates to requirements that are not in the SIP 
and implement other requirements of the CAA.

[[Page 25535]]

F. Federal Standards Adopted by Reference

    The submissions update the most recent Federal regulation 
references in 18 AAC 50.040 ``Federal Standards Adopted by Reference.'' 
In addition, the submissions add a new paragraph (k) to 18 AAC 50.040 
to adopt by reference the provisions of 40 CFR part 64, to the extent 
they apply to title V sources. Paragraph (k) of 18 AAC 50.050 
implements the requirements of 40 CFR parts 64 and 71, and not the 
requirements of section 110 of the CAA. In the absence of a specific 
request from Alaska that this provision be included in the SIP, we are 
proposing to not approve this provision.
Provisions Implementing Other Requirements of the CAA
    The submissions revise paragraphs (a), (b), (c), (d), (e), (g), and 
(j) of 18 AAC 50.040 to update the adoption by reference of emissions 
standards for 40 CFR parts 60, 61, 62, 63, 70, and 82 sources. In 
addition, the submissions add a new paragraph (k) to adopt by reference 
the provisions of 40 CFR part 64 to the extent they apply to title V 
sources.
    These types of provisions are inappropriate for SIP approval 
because they implement other requirements of the CAA, and the State is 
not relying on them to demonstrate attainment or maintenance of the 
NAAQS or to meet other requirements of section 110 of the CAA. We are 
proposing to not approve the addition of subparagraph (j)(9), relating 
to 40 CFR part 71 ``Operating Permits,'' for the same reason.
PSD
    The submissions revise paragraph (h) of 18 AAC 50.040 to adopt by 
reference specific provisions of the Federal PSD regulations set forth 
at 40 CFR 51.166 and 40 CFR 52.21 as of July 1, 2011, to implement the 
Alaska PSD permitting program. However, the submitted revisions 
adopting by reference 40 CFR 52.21(i) (relating to the significant 
monitoring concentration (SMC)) and 40 CFR 52.21(k) (relating to the 
significant impact level (SIL)) have been impacted by a recent court 
decision vacating portions of the 2010 PSD PM2.5 
Implementation Rule (October 20, 2010, 75 FR 64864).
    On January 22, 2013, the U.S. Court of Appeals for the District of 
Columbia, in Sierra Club v. EPA, 703 F.3d 458 (D.C. Cir. 2013), issued, 
with respect to the SMC, a judgment that, inter alia, vacated the 
provisions of the 2010 PSD PM2.5 Implementation Rule adding 
the PM2.5 SMC to the Federal regulations at 
51.166(i)(5)(i)(c) and 52.21(i)(5)(i)(c). In its decision, the Court 
held that the EPA did not have authority to use SMCs to exempt permit 
applicants from the statutory requirement in section 165(e)(2) of the 
CAA that ambient monitoring data for PM2.5 be included in 
all PSD permit applications. Thus, although the PM2.5 SMC 
was not a required element of a state's PSD program, where a state PSD 
program contains such a provision and allows issuance of new permits 
without requiring ambient PM2.5 monitoring data, such 
application of the vacated SMC would be inconsistent with the Court's 
opinion and the requirements of section 165(e)(2) of the CAA.
    At the EPA's request, the decision also vacated and remanded to the 
EPA for further consideration the portions of the 2010 PSD 
PM2.5 Implementation Rule that revised 40 CFR 51.166 and 40 
CFR 52.21 related to SILs for PM2.5. The EPA requested this 
vacatur and remand of two of the three provisions in the EPA 
regulations that contain SILs for PM2.5, because the wording 
of these two SIL provisions (40 CFR 51.166(k)(2) and 40 CFR 
52.21(k)(2)) is inconsistent with the explanation of when and how SILs 
should be used by permitting authorities that we provided in the 
preamble to the Federal Register publication when we promulgated these 
provisions. The third SIL provision (40 CFR 51.165(b)(2)) was not 
vacated and remains in effect. In addition, the Court decision does not 
affect the PSD increments for PM2.5 promulgated as part of 
the 2010 PSD PM2.5 Implementation Rule.
    We note that the EPA recently amended its regulations to remove the 
vacated PM2.5 SILs and SMC provisions from PSD regulations 
on December 9, 2013 (78 FR 73698). In addition, the EPA will initiate a 
separate rulemaking in the future regarding the PM2.5 SILs 
that will address the Court's remand. In the meantime, we are advising 
states to begin preparations to remove the vacated provisions from 
state PSD regulations.
    Consistent with the vacatur of the EPA regulations as they relate 
to the PM2.5 SMC and the PM2.5 SIL, and the EPA's 
December 9, 2013, rulemaking, Alaska has submitted a letter dated 
February 12, 2014, withdrawing the adoption by reference of 40 CFR 
52.21 as it relates to the vacated PM2.5 SMC and SIL at 
subparagraphs 18 AAC 50.040(h)(7) and (9). A copy of Alaska's letter is 
in the docket for this action. Although these provisions remain in 
effect as a matter of State law, Alaska has confirmed that it will not 
apply either the PM2.5 SMC provisions at 40 CFR 
51.166(i)(5)(i)(c) and 52.21 (i)(5)(i)(c), or the PM2.5 SIL 
provisions at 40 CFR 51.166(k)(2) and 52.21(k)(2) in implementing the 
State PSD program. In addition, the letter states that Alaska intends 
to remove the vacated provisions to ensure consistency with Federal 
law.
    The submissions also add subparagraph (21) to 18 AAC 50.040(h) to 
adopt by reference 40 CFR 52.22 ``Enforceable Commitments for Further 
Actions Addressing the Pollutant Greenhouse Gases (GHGs).'' This 
provision is inappropriate for SIP approval because it is related to a 
Federal commitment that is not applicable to the State. Therefore, we 
are proposing to not approve the addition of subparagraph (21).
    In summary, we are proposing to approve the revisions to 18 AAC 
50.040(h) except for subparagraph (21). We are taking no action on 
subparagraphs (7) and (9) because these provisions were withdrawn.
Nonattainment NSR
    The submitted revisions to paragraph (i) of 18 AAC 50.040 update 
the adoption by reference of Federal provisions at 40 CFR 51.165 
``Permit Requirements.'' These provisions govern the permitting of new 
major sources and major modifications in nonattainment areas. On 
February 12, 2014, Alaska submitted a letter to the EPA explaining that 
the Alaska regulations submitted for approval adopt by reference the 
``regulated NSR pollutant'' definition found in the Federal PSD 
permitting regulations at 40 CFR 52.21(b)(50), rather than the 
definition in the Federal nonattainment NSR regulations 40 CFR 
51.165(a)(1)(xxxvii). In the letter, Alaska stated that it intends to 
propose revisions to the appropriate sections of 18 AAC 50 to adopt by 
reference the ``regulated NSR pollutant'' definition at 40 CFR 
51.165(a)(1)(xxxvii) for purposes of nonattainment NSR permitting, and 
to begin the public notice and comment process at the first 
opportunity. The EPA understands the State has already commenced a 
rulemaking to revise the definition of regulated NSR pollutant. In 
light of the commencement of that rulemaking, we are taking no action 
on Alaska's revisions to 18 AAC 50.040(i) at this time, but will 
address the revisions at a later date. We are deferring action on the 
revisions to 18 AAC 50.040(i) to give Alaska the opportunity to revise 
its definition of ``regulated NSR pollutant'' for nonattainment areas 
in 18 AAC 50.040(i)(1)(B)(i).

[[Page 25536]]

G. Industrial Processes and Fuel-Burning Equipment

    In subparagraph (a)(9)(D) of 18 AAC 50.055 ``Industrial Processes 
and Fuel-Burning Equipment, '' the term ``facility'' was replaced by 
the more specific term ``stationary source.'' We are proposing to 
approve this revision because it clarifies that a Federally-approved 
source-specific SIP revision is necessary to change the applicable 
opacity limit at a stationary source located at a facility. In 
addition, consistent with our 2007 action, we are proposing to not 
approve subparagraph (d)(2)(B), which contains emissions standards for 
hydrogen sulfide (72 FR 45378). This provision is inappropriate for SIP 
approval because it is not related to attainment or maintenance of the 
NAAQS or other specific requirements of section 110 of the CAA.

H. Ambient Air Quality Analysis Methods

    The submitted revisions to 18 AAC 50.215 ``Ambient Air Quality 
Analysis Methods'' include revisions to update the methods for 
PM2.5 and ozone, and minor clarifications and edits. The EPA 
proposes to approve the submitted changes, with the exceptions 
described below.
    The submissions add subparagraph (a)(3) to 18 AAC 50.215 to 
reference the EPA's ``Meteorological Monitoring Guidance for Regulatory 
Modeling Applications,'' adopted by reference in 18 AAC 50.035(a). 
Alaska renumbered what was previously subparagraph (a)(3) to (a)(4). 
What is now subparagraph (a)(4) was added in earlier revisions to allow 
ADEC to approve alternative reference test methods for collecting 
ambient monitoring data. In our 2007 action, we did not approve this 
provision because it provides for unbounded director's discretion (72 
FR 45378). Consistent with our 2007 action, we are proposing to not 
approve subparagraph (a)(4), which authorizes ADEC to approve any 
alternative method that ADEC determines is ``representative, accurate, 
verifiable, capable of replication.'' In essence, this subparagraph 
allows ADEC to modify requirements relied on to attain and maintain the 
NAAQS without a SIP revision. For additional discussion, see the TSD 
for our 2007 action, which can be found in the docket for this action. 
See also 78 FR 12460, 12485-86 (February 22, 2013).
    As explained above in the discussion of 18 AAC 50.040(h), because 
40 CFR 51.166(k)(2) and 40 CFR 52.21(k)(2) relating to SILs were 
vacated by the U.S. Court of Appeals for the District of Columbia, and 
subsequently repealed by the EPA, Alaska withdrew the revisions to 
paragraph (d) which update the SILs table and associated SIL-related 
requirements.\2\
---------------------------------------------------------------------------

regarding PM2.5 Significant Impact Levels and Significant 
Monitoring Concentrations, dated February 12, 2014.
---------------------------------------------------------------------------

I. Enforceable Test Methods

    We are proposing to approve the submitted changes to 18 AAC 50.220 
``Enforceable Test Methods'' except for subparagraphs (A), (B), and (C) 
of (c)(1), and all of subparagraph (c)(2), as described below.
    Subparagraph (c)(2) of 18 AAC 50.220 authorizes ADEC to approve the 
use of an alternative method using the procedure specified in 40 CFR 
part 63, Appendix A, Method 301. In essence, subparagraph (c)(2) 
authorizes ADEC to issue variances from regulatory requirements, 
including SIP, New Source Performance Standards (NSPS), and National 
Emission Standards for Hazardous Air Pollutants (NESHAP) requirements. 
Consistent with our 2007 action, we are proposing to not approve 
subparagraph (c)(2), which in essence allows ADEC to modify 
requirements relied on to attain and maintain the NAAQS without a SIP 
revision (72 FR 45378). See also 78 FR 12460, 12485-86 (Feb. 22, 2013).
    In addition, under the authority of CAA section 110(k)(6), we are 
removing from the SIP subparagraphs (A), (B), and (C) of 18 AAC 
50.220(c)(1) because they relate to test methods for CAA requirements 
that are not part of the SIP and implement other provisions of the CAA.

J. Owner-Requested Limits

    We are proposing to approve the revisions to 18 AAC 50.225 ``Owner-
Requested Limits'' paragraph (a) and subparagraph (b)(7) because the 
revisions clarify what can be requested and what needs to be submitted 
for purposes of this provision. The clarifications do not change the 
existing requirements for establishing source-specific limitations 
under 18 AAC 50.225. We are also proposing to approve the addition of 
paragraph (i) to this provision because it provides for the submission 
of certain information and clarifies Alaska's process and effective 
date, but does not change the existing requirements for establishing 
source-specific limitations under this rule.

K. Construction Permits

    The submitted revisions add paragraph (c) to 18 AAC 50.302 
``Construction Permits'' to clarify that a subsequent revision to a 
title V permit term or condition that is solely necessary to meet a 
title V requirement, but was associated with an integrated review 
conducted under 18 AAC 50.306(c)(3), may be processed through the title 
V operating permit amendment or modification provisions of 18 AAC 
50.326. We are proposing to approve this new provision because it is 
appropriate and consistent with the CAA for revisions made solely for 
title V purposes to be revised using the title V amendment or 
modification provisions.
    In addition, under the authority of CAA section 110(k)(6), we are 
removing from the SIP subparagraph (a)(3) of this provision, because it 
relates to major sources of hazardous air pollutants. This provision 
implements other requirements of the CAA and the State has not relied 
on this requirement to demonstrate attainment or maintenance of the 
NAAQS or to meet other specific requirements of section 110 of the CAA.

L. Prevention of Significant Deterioration (PSD) Permits

    Alaska's PSD program was originally approved into the SIP by the 
EPA on July 5, 1983, and has been revised several times since the 
original approval. The most recent major revision to Alaska's PSD 
program was approved by the EPA in our 2007 action (72 FR 45378). In 
general, Alaska chooses to adopt by reference the Federal PSD rules in 
40 CFR 52.21 rather than the comparable provisions in 40 CFR 51.166, 
which set forth what is required in a State's plan, because 40 CFR 
52.21 is written to directly state the requirements of an owner or 
operator. In some cases, Alaska adopted provisions of 40 CFR 51.166 
rather than the comparable provisions of 40 CFR 52.21 because 40 CFR 
51.166 was a better fit for a SIP-approved PSD program.
    Key submitted changes to 18 AAC 50.306 ``Prevention of Significant 
Deterioration (PSD) Permits'' include the definition of ``national 
ambient air quality standard,'' which is revised to mean ``an ambient 
air quality standard set out in 18 AAC 50.010 for this state'' and 
``ambient air increment'' or ``maximum allowable increase,'' which is 
revised to mean a maximum allowable increase calculated as described in 
18 AAC 50.020 ``Baseline Dates and Maximum Allowable Increases.'' We 
are proposing to approve the definition of ``national ambient air

[[Page 25537]]

quality standard'' because the referred-to State ambient air quality 
standards in 18 AAC 50.010 include the Federal 2006 PM2.5 
NAAQS, 2008 ozone NAAQS, 2008 Pb NAAQS, 2010 SO2 NAAQS, and 
2010 NO2 NAAQS in 40 CFR part 50. The EPA's understanding is 
that the previous reference to ``national ambient air quality 
standard'' in this provision referred to the NAAQS as last adopted by 
reference by ADEC, so that the change in reference from ``national 
ambient air quality standard'' to ``ambient air quality standards in 18 
AAC 50.010'' is not a substantive change. It will remain important for 
ADEC to revise 18 AAC 50.010 promptly after Federal revisions to the 
NAAQS so that its PSD program continues to meet Federal requirements.
    In addition, we are proposing to approve in subparagraph (b)(1)(C) 
the definition of ``ambient air increment'' or ``maximum allowable 
increase'' because it appropriately refers to the established maximum 
allowance increases that Alaska has set out in Table 3 of 18 AAC 
50.020(b). We are proposing to approve the other submitted 
clarifications to this rule because they meet the requirements of the 
CAA.

M. Construction, Minor and Operating Permits: Standard Permit 
Conditions

    We are proposing to approve the submitted revisions to 18 AAC 
50.345 ``Construction, Minor and Operating Permits: Standard Permit 
Conditions'' because they meet the requirements of the CAA, with the 
exception of paragraph (l). Paragraph (l) gives ADEC unbounded 
discretion to change the source testing requirements of a Federally-
enforceable permit without revising the permit. Consistent with our 
2007 action, we are proposing to not approve paragraph (l) (72 FR 
45378). See also 78 FR 12460, 12485-86 (Feb. 22, 2013)

N. Construction and Operating Permits: Other Permit Conditions

    Alaska submitted revisions to paragraphs (a), (b) and (c) of 18 AAC 
50.346 ``Construction and Operating Permits: Other Permit Conditions.'' 
Consistent with our 2007 action, we are proposing to not approve 18 AAC 
50.346(a) because this provision only requires corrective action after 
the permittee or ADEC, determines a violation has occurred and thus 
cannot be construed as monitoring to assure compliance (72 FR 45378). 
In addition, we are proposing to not approve paragraphs (b) and (c) 
because the provisions implement requirements of title V of the CAA, 
and not requirements of section 110 of title I of the CAA.

O. Permit Administration Fees

    Alaska submitted revisions to paragraphs (a), (e), (g), (h), (i), 
and (m), and subparagraphs (j)(19) and (20) of 18 AAC 50.400 ``Permit 
Administration Fees.'' We are proposing to approve the fee provisions 
in 18 AAC 50.400(e), (g), (h), (i), (j)(19) and (j)(20) because these 
provisions implement SIP requirements. We are proposing to not approve 
paragraph (a) of this provision because it implements requirements of 
title V of the CAA and not requirements of section 110 of title I of 
the CAA. In addition, it is not necessary to act on paragraph (m), 
which was repealed, because that provision is not currently in the 
Federally-approved Alaska SIP.

P. Minor Permits for Air Quality Protection

    The Alaska submissions revise subparagraphs (c)(1), (2), and (3) of 
18 AAC 50.502 ``Minor Permits for Air Quality Protection'' to 
appropriately refer to ``beginning actual construction,'' ``beginning 
relocation,'' and ``beginning a physical change to or a change in 
operation.'' The previous version of these provisions required an owner 
or operator to obtain a minor permit before commencing construction, 
relocation, or a physical change, which corresponded generally to a 
date that occurs before actual construction begins. The CAA, however, 
does not require a state to tie the obligation to obtain a minor permit 
to the commence construction date, or to a date that occurs before 
actual construction begins. Alaska has, accordingly, changed the 
requirements to obligate a source to obtain a minor permit before 
``beginning actual construction,'' ``beginning relocation,'' or 
``beginning a physical change,'' consistent with CAA requirements. We 
are proposing to approve these revisions.
    The submissions also add subparagraphs (c)(1)(F), (c)(3)(A)(v) and 
(c)(3)(B)(v) to 18 AAC 50.502 to establish PM2.5 thresholds 
for determining whether the owner or operator of a stationary source 
must obtain a minor permit for PM2.5. These new 
subparagraphs strengthen the SIP by requiring stationary sources of 
PM2.5 above the specified thresholds to obtain a minor 
permit. These provisions are consistent with Federal requirements in 40 
CFR 51.160 through 164, and are approvable. Finally, we are proposing 
to approve 18 AAC 50.502(e), (g), and (i) because they are consistent 
with CAA requirements and are clarifications to existing Federally-
approved rules.

Q. Minor Permits Requested by the Owner or Operator

    The submissions revise 18 AAC 50.508 ``Minor Permits Requested by 
the Owner or Operator'' by clarifying terms and cross-references, and 
repealing provisions that have been repealed at the Federal level. We 
are proposing to approve these revisions because they are consistent 
with the CAA.

R. Minor Permit--Title V Permit Interface

    The submissions add a new provision, 18 AAC 50.510 ``Minor Permit--
Title V Permit Interface,'' which provides that certain terms or 
conditions established in a minor permit at 18 AAC 50.542 solely for 
title V purposes can be revised through the applicable title V revision 
process. We are proposing to approve this provision because it makes 
permit terms established in a minor permit, solely under the authority 
of title V, subject to the title V permit revision provisions.

S. Minor Permit: Application

    We are proposing to approve the submitted revisions to 18 AAC 
50.540 ``Minor Permit: Application.'' Specifically, we are proposing to 
approve the revision to subparagraph (c)(2) to clarify the air quality 
analysis methods for demonstrating attainment or maintenance of the 
ambient air quality standards. We also are proposing to approve the 
NO2 exception in 50.540(l) because it only pertains to the 
content of the application, and does not change the requirements for 
air quality analysis during the permit review process that continue to 
apply under 18 AAC 50.542(f). Finally, we are proposing to approve the 
revisions to 18 AAC 50.540(d), (j), and (k) because they either clarify 
existing rule language or add requirements that will assist in the 
implementation of these provisions.

T. Minor Permit: Review and Issuance

    The submissions revise 18 AAC 50.542 ``Minor Permit: Review and 
Issuance'' in several places. We are proposing to approve the revision 
to paragraph (a), excluding sources in the additional areas of the 
Municipality of Anchorage, the City of Fairbanks, Fort Wainwright, and 
Eielson Air Force Base from fast track procedures. In these areas, ADEC 
will provide a 30-day public comment period for sources regardless of 
whether a public comment period was requested. We also are proposing to 
approve, in subparagraph (c)(2)(A), the addition of a PM2.5 
screening level because it is reasonable and appropriate to offer the 
fast-track procedure to sources that can show

[[Page 25538]]

compliance with the NAAQS using a conservative approach. The screening 
level of 50 percent of the PM2.5 standard is set well below 
the ambient air quality standard for PM2.5 and appropriately 
conservative for showing compliance.
    In addition, we are proposing to approve, in subparagraph 
(c)(2)(D), an alternative way to determine if the fast-track procedure 
in subparagraph (c)(2) is available for a modification. This provision 
is approvable because it is an appropriately conservative approach that 
relies on the highest predicted concentrations for use in comparing to 
the ambient air quality standard and is appropriately conservative for 
showing compliance.
    Consistent with our 2007 action (72 FR 45378), we are proposing to 
approve the remaining portion of 18 AAC 50.542, except subparagraph 
(b)(2). Subparagraph (b)(2) allows ADEC to require the owner/operator 
to submit a permit application online. Alaska did not submit the 
appropriate documentation to allow the EPA to evaluate the 
approvability of Alaska's Online System with respect to the EPA's 
Cross-Media Electronic Reporting Rule (CROMERR). See 70 FR 59848 
(October 13, 2005). Therefore, we are proposing to not approve 
subparagraph (b)(2).

U. Minor Permits: Content

    The submissions revise 18 AAC 50.544 ``Minor Permits: Content,'' a 
provision that sets forth what a minor permit must contain. We are 
proposing to approve the submitted revisions to subparagraphs (a)(5) 
and (6) because they correspond to the clarification in 18 AAC 50.345 
that requires the standard permit conditions of 18 AAC 50.345 to apply 
to minor permits. We are also proposing to approve subparagraph (a)(7) 
because this provision establishes the process for accommodating an 
owner or operator request to add the conditions of a minor permit to a 
title V permit, and because this provision is not contrary to any CAA 
requirement. Finally, we are proposing to approve subparagraph (c)(3) 
and paragraph (h) as clarifications of the terms and conditions that 
are required to be included in a permit.

V. Minor Permits: Revisions

    We are proposing to approve 18 AAC 50.546 ``Minor Permits: 
Revisions,'' except paragraph (b), which authorizes ADEC to revise 
``non-substantive elements of a minor permit without further 
administrative procedures.'' As discussed in our 2007 action, we did 
not approve paragraph (b) because it does not adequately define the 
class of revisions that can be made without public review (72 FR 
45378). For the same reason, we are proposing to not approve paragraph 
(b) in this action.

W. Conformity

    Revisions to the regulations in Article 7 ``Conformity'' of 18 AAC 
50 were submitted in Alaska's October 21, 2011, submission. We are not 
addressing these revisions in this action. We intend to address these 
revisions in a separate action.

X. Definitions

    18 AAC 50.990 ``Definitions,'' defines terms and also adopts by 
reference applicable definitions set forth in Federal rules. We are 
proposing to approve the submitted revisions to this provision because 
they meet the requirements of the CAA. Specifically, we are proposing 
to approve the repeal of the definitions of ``clean unit,'' ``expected 
arithmetic mean,'' ``expected number'' and ``pollution control 
project'' because the EPA has previously revoked or repealed the 
related Federal provision requiring the definition. In addition, we are 
proposing to approve the updated definition of ``good engineering 
practice stack height'' to reference the requirements of 40 CFR 
51.100(ii) as revised as of July 1, 2007, and as currently in effect.
    We are also proposing to approve the revisions to the definitions 
of ``impairment of visibility,'' ``modification'' or ``modify,'' 
``nonroad engine,'' ``reconstruct'' and ``reconstruction,'' ``regulated 
air pollutant,'' ``regulated NSR pollutant'' (except that we are 
deferring action on this definition as it relates to 18 AAC 50.040(i) 
(nonattainment NSR)), ``volatile organic compound,'' ``PAL,'' 
``regional administrator,'' ``PM-2.5,'' ``transportation improvement 
plan,'' ``CO2 equivalent emissions,'' and ``greenhouse gases'' because 
they reflect the already-established Federal definitions for these 
terms.

Y. Statutes

    In addition to our review of regulatory changes to 18 AAC 50, we 
reviewed Alaska statutory provisions submitted as part of the January 
28, 2013, submission. Specifically, the submission included portions of 
Alaska Statutes Chapters 44.46 ``Department of Environmental 
Conservation;'' 46.03 ``Declaration of Policy;'' and 46.14 ``Air 
Quality Control.'' Based on our review, these submitted statutes 
continue to provide Alaska with adequate legal authority to carry out 
the requirements of the Alaska SIP as set forth in sections 110 and 114 
of the CAA and its implementing regulations, in particular 40 CFR 
51.230.
    Certain aspects and provisions, however, merit further discussion. 
First, the EPA's authority to approve SIPs extends to provisions 
related to attainment and maintenance of the NAAQS, and carrying out 
other specific requirements of section 110 of the CAA. Therefore, our 
review of the submitted statutory provisions is limited in that 
respect.
    Second, AS 46.14.540 ``Authority of Department in Cases of 
Emergency'' states that, under certain circumstances, the commissioner 
may waive procedural requirements of AS Chapter 46.14 and issue an 
order to authorize emergency use of the emissions unit. This statutory 
provision authorizes ADEC to issue a variance to State regulations 
approved into the SIP without meeting state regulatory requirements for 
revising a regulation or permit and without a SIP revision. Section 
110(i) of the CAA, however, specifically precludes states from changing 
the requirements of the SIP, except through SIP revisions approved by 
the EPA as provided in section 110 of the CAA and the implementing 
regulations at 40 CFR 51.100 to 51.105. See 78 FR 12460, 12485-86 (Feb. 
22, 2013). For these reasons, we are proposing to not approve AS 
46.14.540 ``Authority of Department in Cases of Emergency'' into the 
SIP.
    Third, AS 46.14.560 ``Unavoidable Malfunctions and Emergencies'' 
provides an affirmative defense to an action for noncompliance with a 
technology-based emission standard for excess emissions ``caused by an 
unavoidable emergency, a malfunction, or nonroutine repairs of an 
emissions unit'' when asserted under regulations adopted by ADEC under 
AS 46.14.140. This statutory provision is the basis for 18 AAC 50.240 
``Excess Emissions.'' Both AS 46.14.560 and 18 AAC 50.240 were 
previously approved into the Alaska SIP. The current SIP submission 
includes a resubmission of AS 46.14.560, with two minor changes, but 
does not include a resubmission of 18 AAC 50.240.
    On February 22, 2013, the EPA proposed a SIP call in which the EPA 
identified deficiencies in the startup, shutdown, and malfunction 
provisions of numerous states, including Alaska's regulation 18 AAC 
50.240 (78 FR 12460) (proposed SSM SIP call). In light of the proposed 
SSM SIP call, we are taking no action on Alaska's submission of AS 
46.14.560 at this time, but rather will take action on the submission 
at a later date.

[[Page 25539]]

    Fourth, AS 46.14.510(b) relates to maintenance of motor vehicle air 
pollution control equipment. We incorporated by reference AS 
46.14.510(b) on November 18, 1998 (63 FR 63983). In this action, we are 
removing the incorporation by reference of AS 46.14.510(b) because the 
provision is addressed by incorporation by reference elsewhere in the 
Federally-approved SIP (at 18 AAC 52.015(a), (b), 52.990(66)(B) and 
52.100(d)(3)).
    In general, we are not proposing to incorporate by reference the 
statutory provisions submitted by Alaska to avoid potential conflict 
with the EPA's independent authorities. However, we are proposing to 
continue to incorporate by reference updated AS 46.14.550 and the 
definitions in updated AS 46.14.990, where a definition in 18 AAC 
50.990 states that it has the meaning given in AS 46.14.990, and where 
it relates to attainment or maintenance of the NAAQS or other specific 
requirements of section 110 of the CAA. These incorporated by reference 
definitions are AS 46.14.990 (4) ``building, structure, facility, or 
installation,'' (5) ``commissioner,'' (8) ``department,'' (15) ``local 
air quality control program,'' (16) ``major modification,'' (17) 
``major stationary source,'' (18) ``operating permit,'' and (27) ``tank 
vessel.''

III. Proposed Action

Provisions the EPA Is Proposing To Approve and Incorporation by 
Reference
    Consistent with the discussion and analysis above, the EPA is 
proposing to approve into the SIP at 40 CFR part 52, subpart C, the 
Alaska laws and regulations listed in the table below. Note that in 
those instances where ADEC submitted multiple revisions to a single 
section of 18 AAC 50, the most recent version of that section (based on 
state effective date) is proposed to be incorporated into the SIP as it 
supersedes all previous revisions.

    As discussed above, EPA proposes to find that the statutes 
submitted by ADEC in its SIP revisions, with the exceptions discussed 
above, continue to provide Alaska with adequate legal authority to 
carry out the requirements of the Alaska SIP. In general, the EPA is 
not proposing to incorporate by reference the statutory provisions 
submitted by Alaska to avoid potential conflict with the EPA's 
independent authorities.
Provisions the EPA Is Proposing To Not Approve
    We are proposing to not approve the following provisions for the 
reasons explained above and in the TSD:
     18 AAC 50.010 ``Ambient Air Quality Standards,'' 
paragraphs (7) and (8).
     18 AAC 50.030 ``State Air Quality Control Plan.''
     18 AAC 50.035 ``Documents, Procedures, and Methods Adopted 
by Reference,'' subparagraphs (a)(6) and (b)(4).
     18 AAC 50.040 ``Federal Standards Adopted by Reference,'' 
paragraphs (a), (b), (c), (d), (e), (g), (j) and (k), and subparagraph 
(h)(21).
     18 AAC 50.055 ``Industrial Processes and Fuel-Burning 
Equipment,'' subparagraph (d)(2)(B).
     18 AAC 50.215 ``Ambient Air Quality Analysis Methods,'' 
subparagraph (a)(4).

[[Page 25540]]

     18 AAC 50.220 ``Enforceable Test Methods,'' subparagraph 
(c)(2).
     18 AAC 50.326 ``Title V Operating Permits, paragraph (e).
     18 AAC 50.345 ``Construction and Operating Permits: 
Standard Permit Conditions,'' paragraph (l).
     18 AAC 50.346 ``Construction and operating permits: Other 
permit conditions,'' paragraphs (a), (b) and (c).
     18 AAC 50.400 ``Permit Administration Fees,'' paragraph 
(a).
     18 AAC 50.542 ``Minor Permit: Review and Issuance,'' 
subparagraph (b)(2).
     18 AAC 50.546 ``Minor Permits: Revisions,'' paragraph (b).
     AS 46.14.540 ``Authority of Department in Cases of 
Emergency.''
Provisions the EPA Is Removing From the SIP or From Incorporation by 
Reference
    Under the authority of CAA section 110(k)(6), we are removing the 
following provisions from the SIP because they implement other 
requirements of the CAA and the State has not relied on these 
provisions to demonstrate attainment or maintenance of the NAAQS or to 
meet other specific requirements of section 110 of the CAA: 18 AAC 
50.220(c)(1)(A), (B), (C) and 18 AAC 50.302(a)(3). We are also removing 
AS 46.14.510(b), which was incorporated by reference on November 18, 
1998 (63 FR 63983). However, we have determined that the provision is 
addressed by incorporation by reference elsewhere in the Federally-
approved SIP.
Provisions the EPA Is Taking No Action On
    Finally, as detailed above and in the TSD, we are taking no action 
on the following Alaska provisions: 18 AAC 50.040 ``Federal Standards 
Adopted by Reference'' paragraph (i) (adoption by reference of Federal 
nonattainment NSR regulations at 40 CFR 51.165); 18 AAC 50 Article 7 
``Conformity;'' and AS 46.14.560 ``Unavoidable Malfunctions and 
Emergencies.'' We intend to address these changes in a separate action.

IV. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, the EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves state law as meeting Federal requirements and 
does not impose additional requirements beyond those imposed by state 
law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     is not subject to the requirements of section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because this action does not involve technical standards; and
     does not provide the EPA with the discretionary authority 
to address, as appropriate, disproportionate human health or 
environmental effects, using practicable and legally permissible 
methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the State, and the EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.
