SUPPLEMENTARY INFORMATION: 

I. What action is the agency taking?

    On May 8, 2013, and August 23, 2016, ADEM submitted SIP revisions 
for EPA's approval that include changes to Alabama's PSD permitting 
regulations, among other changes.\1\ In this document, EPA is proposing 
to approve certain portions of these submittals that make changes to 
ADEM Administrative Code Rule 335-3-14-.04--``Air Permits Authorizing 
Construction in Clean Areas (Prevention of Significant Deterioration 
(PSD),'' which applies to the construction or modification of any major 
stationary source in areas designated as attainment or unclassifiable 
as required by part C of title I of the CAA.
---------------------------------------------------------------------------

    \1\ EPA's regulations governing the implementation of New Source 
Review (NSR) permitting programs are contained in 40 CFR 51.160-
51.166; 52.21, 52.24; and part 51, Appendix S. The CAA NSR program 
is composed of three separate programs: PSD, NNSR, and Minor NSR. 
PSD is established in part C of title I of the CAA and applies in 
areas that meet the NAAQS--``attainment areas''--as well as areas 
where there is insufficient information to determine if the area 
meets the NAAQS--``unclassifiable areas.'' The NNSR program is 
established in part D of title I of the CAA and applies in areas 
that are not in attainment of the NAAQS--``nonattainment areas.'' 
The Minor NSR program addresses construction or modification 
activities that do not qualify as ``major'' and applies regardless 
of the designation of the area in which a source is located. 
Together, these programs are referred to as the NSR programs.
---------------------------------------------------------------------------

    Alabama's May 8, 2013 SIP submittal includes changes to Rule 335-3-
14-.04 to address the Federal rule entitled ``Implementation of the New 
Source Review (NSR) Program for Particulate Matter Less Than 2.5 
Micrometers (PM2.5):\2\ Amendment to the Definition of 
`Regulated NSR Pollutant' Concerning Condensable Particulate Matter,'' 
77 FR 65107 (October 25, 2012) (hereinafter referred to as the 
PM2.5 Condensables Correction Rule), and plantwide 
applicability limits (PALs) for greenhouse gases (GHGs) as allowed in 
the Federal rule entitled ``Prevention of Significant Deterioration and 
Title V Greenhouse Gas Tailoring Rule Step 3 and GHG Plantwide 
Applicability Limits,'' 77 FR 41051 (July 12, 2012) (hereinafter 
referred to as the GHG Step 3 Rule). In addition, the SIP submittal 
includes changes to the definition of GHGs in Rule 335-3-14-.04 and 
Rule 335-3-16 (regarding major source operating permits) to address 
EPA's July 20, 2011 rule deferring PSD requirements for carbon dioxide 
(CO2) emissions from bioenergy and other biogenic sources 
(hereinafter referred to as the ``Biomass Deferral Rule'').\3\ 
Alabama's May 8, 2013 SIP submission also includes the following 
changes to other Alabama rules: changes to the definition of Volatile 
Organic Compounds (VOCs) at Rule 335-3-1-.02; changes to the 
incorporation by reference (IBR) of the Federal New Source Performance 
Standards (NSPS) in Chapter 335-3-10 and National Emissions Standards 
for Hazardous Air Pollutants (NESHAPs) in Chapter 335-3-11; and changes 
regarding transportation conformity provisions at Rule Chapter 335-3-
16.
---------------------------------------------------------------------------

    \2\ Airborne particulate matter (PM) with a nominal aerodynamic 
diameter of 2.5 micrometers or less (a micrometer is one-millionth 
of a meter, and 2.5 micrometers is less than one-seventh the average 
width of a human hair) are considered to be ``fine particles'' and 
are also known as PM2.5. Fine particles in the atmosphere 
are made up of a complex mixture of components including sulfate; 
nitrate; ammonium; elemental carbon; a great variety of organic 
compounds; and inorganic material (including metals, dust, sea salt, 
and other trace elements) generally referred to as ``crustal'' 
material, although it may contain material from other sources. The 
health effects associated with exposure to PM2.5 include 
potential aggravation of respiratory and cardiovascular disease 
(i.e., lung disease, decreased lung function, asthma attacks and 
certain cardiovascular issues). On July 18, 1997, EPA revised the 
NAAQS for PM to add new standards for fine particles, using 
PM2.5 as the indicator. Previously, EPA used 
PM10 (inhalable particles smaller than or equal to 10 
micrometers in diameter) as the indicator for the PM NAAQS. EPA 
established health-based (primary) annual and 24-hour standards for 
PM2.5, setting an annual standard at a level of 15.0 
micrograms per cubic meter ([micro]g/m\3\) and a 24-hour standard at 
a level of 65 [micro]g/m\3\ (62 FR 38652). At the time the 1997 
primary standards were established, EPA also established welfare-
based (secondary) standards identical to the primary standards. The 
secondary standards are designed to protect against major 
environmental effects of PM2.5, such as visibility 
impairment, soiling, and materials damage. On October 17, 2006, EPA 
revised the primary and secondary 24-hour NAAQS for PM2.5 
to 35 [micro]g/m\3\ and retained the existing annual 
PM2.5 NAAQS of 15.0 [micro]g/m\3\ (71 FR 61236). On 
January 15, 2013, EPA published a final rule revising the annual 
PM2.5 NAAQS to 12 [micro]g/m\3\ (78 FR 3086).
    \3\ Emissions of CO2 from a stationary source 
directly resulting from the combustion or decomposition of 
biologically-based materials other than fossil fuels and mineral 
sources of carbon (e.g., calcium carbonate) and biologically-based 
material (non-fossilized and biodegradable organic material 
originating from plants, animals or micro-organisms, including 
products, by-products, residues and waste from agriculture, forestry 
and related industries as well as the non-fossilized and 
biodegradable organic fractions of industrial and municipal wastes, 
including gases and liquids recovered from the decomposition of non-
fossilized and biodegradable organic material).
---------------------------------------------------------------------------

    Alabama's August 23, 2016 SIP submittal includes changes to Rule 
335-3-14-.04 and Rule Chapter 335-3-16 to remove the treatment of GHGs 
as an air pollutant for the specific purpose of determining whether a 
source is a major source (or a modification thereof) in PSD and title V 
permitting requirements for the reasons discussed in Section II.A, 
below. The submittal also withdraws the portion of the State's May 8, 
2013 SIP submittal that revises Rule 335-3-14-.04 to address the 
Biomass Deferral Rule and makes changes to the GHG Step 3 language 
proposed in Alabama's May 8, 2013 submittal.
    Currently, EPA is only proposing to approve the portions of the May 
8, 2013 submittal that make changes to the GHG

[[Page 38662]]

PAL provisions pursuant to the GHG Step 3 rule and the portions of the 
August 23, 2016 submittal that discontinue regulation of GHGs as an air 
pollutant for the specific purpose of determining whether a source is a 
major source (or a modification thereof) in PSD and title V permitting 
requirements and that make changes to the GHG Step 3 language proposed 
in Alabama's May 8, 2013 submittal. EPA is not acting on the remaining 
portions of these submittals for the following reasons:
     EPA previously acted upon the changes to the definition of 
VOCs at Rule 335-3-1-.02. See 81 FR 63701 (September 16, 2016).
     The revisions that address the Regulated PM2.5 
Condensables Correction Rule are unnecessary because the errors 
corrected by the Rule were never incorporated into Alabama's SIP.\4\ 
See 77 FR 59100 (September 26, 2012).
---------------------------------------------------------------------------

    \4\ In a May 2, 2011 SIP revision, Alabama requested that EPA 
incorporate the term ``Particulate matter (PM)'' emissions into its 
SIP-approved definition of ``regulated NSR pollutant'' at Rule 335-
3-14-.04(2)(ww)5, among other changes. Following EPA's proposed 
approval of the PM2.5 Condensables Correction Rule, 
Alabama submitted a supplemental letter on June 18, 2012, requesting 
that EPA not approve the proposed change at 335-3-14-.04(2)(ww)5 
when taking action on the May 2, 2011, SIP revision.
---------------------------------------------------------------------------

     EPA will act on the transportation conformity revisions in 
a separate action.
     In its August 23, 2016 SIP revision, Alabama withdrew the 
portion of its May 8, 2013 SIP revision that addressed the Biomass 
Deferral Rule.
     ADEM Administrative Code Chapter 335-3-10--``Standards of 
Performance for New Stationary Sources,'' Chapter 335-3-11--``National 
Emission Standards for Hazardous Air Pollutants,'' and Chapter 335-3-
16--``Major Source Operating permits,'' are not part of Alabama's SIP; 
therefore, EPA cannot make the changes to these regulations.

II. Background

    On January 2, 2011, GHG emissions were, for the first time, covered 
by the PSD and title V operating permit programs.\5\ To establish a 
process for phasing in the permitting requirements for stationary 
sources of GHGs under the CAA PSD and title V programs, on June 3, 
2010, EPA published a final rule entitled ``Prevention of Significant 
Deterioration and Title V Greenhouse Gas Tailoring Rule'' (hereinafter 
referred to as the GHG Tailoring Rule). See 75 FR 31514. In Step 1 of 
the GHG Tailoring Rule, which began on January 2, 2011, EPA limited 
application of PSD and title V requirements to sources and 
modifications of GHG emissions, but only if they were subject to PSD or 
title V ``anyway'' due to their emissions of pollutants other than 
GHGs. These sources are referred to as ``anyway sources.''
---------------------------------------------------------------------------

    \5\ See the rule entitled ``Reconsideration of Interpretation of 
Regulations that Determine Pollutants Covered by Clean Air Act 
Permitting Programs,'' Final Rule, 75 FR 17004 (April 2, 2010).
---------------------------------------------------------------------------

    In Step 2 of the GHG Tailoring Rule, which applied as of July 1, 
2011, the PSD and title V permitting requirements applied to some 
sources that were classified as major sources based solely on their GHG 
emissions or potential to emit GHGs. Step 2 also applied PSD permitting 
requirements to modifications of otherwise major sources that would 
increase only GHG emissions above the level in EPA regulations. EPA 
generally described the sources covered by PSD during Step 2 of the 
Tailoring Rule as ``Step 2 sources'' or ``GHG-only sources.''
    Subsequently, EPA published the GHG Step 3 Rule on July 12, 2012. 
See 77 FR 41051. In this rule, EPA decided against further phase-in of 
the PSD and title V requirements for sources emitting lower levels of 
GHG emissions. Thus, the thresholds for determining PSD applicability 
based on emissions of GHGs remained the same as established in Steps 1 
and 2 of the Tailoring Rule.
    The GHG PALs portion of the July 12, 2012 final rule revised EPA 
regulations under 40 CFR part 52 for establishing PALs for GHG 
emissions. A PAL establishes a site-specific plantwide emission level 
for a pollutant that allows the source to make changes at the facility 
without triggering the requirements of the PSD program, provided that 
its actual emissions at the facility do not exceed the PAL level. Prior 
to the July 12, 2012 rule, PALs were available for non-GHG pollutants 
and for GHGs on a mass basis. EPA's rule revised the PAL regulations to 
allow for GHG PALs to be established on a carbon dioxide equivalent 
(CO2e)\6\ basis, as well as a mass basis. See 77 FR 41051 
(July 12, 2012). These regulatory changes provided sources with 
flexibility in implementing PALs for GHGs.
---------------------------------------------------------------------------

    \6\ CO2e emissions refers to emissions of six 
recognized GHGs other than CO2 which are scaled to 
equivalent CO2 emissions by relative global warming 
potential values, then summed with CO2 to determine a 
total equivalent emissions value. See 40 CFR 51.166(48)(ii) and 
52.21(49)(ii).
---------------------------------------------------------------------------

    On June 23, 2014, the U.S. Supreme Court addressed the application 
of stationary source permitting requirements to GHG emissions in 
Utility Air Regulatory Group (UARG) v. EPA, 134 S. Ct. 2427 (2014). The 
Supreme Court upheld EPA's regulation of GHG Step 1--or ``anyway'' 
sources--but held that EPA may not treat GHGs as air pollutants for the 
purpose of determining whether a source is a major source (or is 
undergoing a major modification) and thus require the source to obtain 
a PSD or title V permit. Therefore, the Court invalidated PSD and title 
V permitting requirements for GHG Step 2 sources.
    In accordance with the Supreme Court decision, on April 10, 2015, 
the D.C. Circuit issued an Amended Judgment vacating the regulations 
that implemented Step 2 of the GHG Tailoring Rule, but not the 
regulations that implement Step 1 of the GHG Tailoring Rule. Coalition 
for Responsible Regulation, Inc. v. EPA, 606 Fed. Appx. 6, 7 (D.C. Cir. 
2015). The D.C. Circuit's Judgment specifically vacated the EPA 
regulations under review (including 40 CFR 51.166(b)(48)(v) and 40 CFR 
52.21(b)(49)(v)) ``to the extent they require a stationary source to 
obtain a PSD permit if greenhouse gases are the only pollutant (i) that 
the source emits or has the potential to emit above the applicable 
major source thresholds, or (ii) for which there is a significant 
emissions increase from a modification.'' Id. at 7-8.
    EPA promulgated a good cause final rule on August 19, 2015, 
entitled ``Prevention of Significant Deterioration and Title V 
Permitting for Greenhouse Gases: Removal of Certain Vacated Elements.'' 
See 80 FR 50199 (August 19, 2015) (hereinafter referred to as the Good 
Cause GHG Rule). The rule removed from the Federal regulations the 
portions of the PSD permitting provisions for Step 2 sources that were 
vacated by the D.C. Circuit (i.e., 40 CFR 51.166(b)(48)(v) and 
52.21(b)(49)(v)). EPA therefore no longer has the authority to conduct 
PSD permitting for Step 2 sources, nor can the Agency approve 
provisions submitted by a state for inclusion in their SIP providing 
this authority. In addition, on October 3, 2016, EPA proposed to revise 
provisions in the PSD permitting regulations applicable to GHGs to 
address the GHG applicability threshold for PSD in order to fully 
conform with UARG and the Amended Judgment, but those revisions have 
not been finalized. See 81 FR 68110.

III. Analysis of the State's Submittals

A. Alabama's May 8, 2013 Submittal

    Alabama's May 8, 2013 SIP submittal seeks to add to the Alabama SIP 
elements of EPA's July 12, 2012 rule implementing Step 3 of the phase-
in of PSD permitting requirements for GHGs

[[Page 38663]]

described in the GHG Step 3 Rule by modifying a PAL provision at Rule 
335-3-14-.04(23)(b)4.\7\ As explained in Section II above, a PAL 
establishes a site-specific plantwide emission level for a pollutant 
that allows the source to make changes to units at the facility without 
triggering the requirements of the PSD program, provided that facility-
wide emissions do not exceed the PAL.
---------------------------------------------------------------------------

    \7\ As discussed in Section I above, EPA is not acting on the 
remaining portions of this submittal.
---------------------------------------------------------------------------

    The Federal PSD regulations currently include PAL provisions that 
apply to GHG-only, or Step 2, sources. However, some of these 
provisions may no longer be applicable in light of the Supreme Court's 
decision in UARG and the D.C. Circuit's Amended Judgment. The Supreme 
Court determined that sources and modifications may not be defined as 
``major'' solely on the basis of GHGs emitted or increased, and 
consequently PALs for GHGs may no longer be authorized in instances in 
which a source has triggered PSD based on GHG emissions alone. EPA has 
proposed action in an October 3, 2016 proposed rule to clarify the GHG 
PAL rules. See 81 FR 68110. However, PALs for GHGs may still have a 
role to play in determining whether a source that is already subject to 
PSD for a pollutant other than GHGs should also be subject to PSD for 
GHGs. The existing GHG PALs regulations do not add new requirements for 
sources or modifications that only emit or increase GHGs above the 
major source threshold, or the 75,000 ton per year (tpy) GHG level in 
40 CFR 52.21(b)(49)(iv), but rather provide increased flexibility to 
sources that wish to manage their GHG emissions by way of a PAL.
    In its May 8, 2013 SIP submittal, Alabama seeks to modify the 
definition of ``major emissions unit'' in its SIP-approved PAL 
regulations by adding the phrase ``any emissions unit that has the 
potential to emit 100,000 tons per year of GHG as CO2e.'' The State 
subsequently revised this threshold from 100,000 tpy to 75,000 tpy as 
part of its August 23, 2016 submittal, as discussed below. Given this 
subsequent revision, the text that EPA is proposing to add to the SIP-
approved definition of ``major emissions unit'' at Rule 335-3-
14-.04(23)(b)4. reads as follows: ``any emissions unit that has the 
potential to emit 75,000 tons per year of GHG as CO2e'' into the SIP-
approved definition of ``major emissions unit'' at Rule 335-3-
14-.04(23)(b)4.
    EPA has preliminarily concluded that approving these changes into 
the SIP will not interfere with any applicable requirement concerning 
attainment and reasonable further progress (as defined in section 171), 
or any other applicable requirement of the CAA. EPA discussed the 
effects of PALs in the Supplemental Analysis of the Environmental 
Impact of the 2002 Final NSR Improvement Rules (November 21, 2002) 
(2002 Supplemental Analysis). The Supplemental Analysis explained, 
``[t]he EPA expects that the adoption of PAL provisions will result in 
a net environmental benefit. Our experience to date is that the 
emissions caps found in PAL-type permits result in real emissions 
reductions, as well as other benefits.'' Supplemental Analysis at 6; 
see also 76 FR 49313, 49315 (August 10, 2011). EPA further discussed 
the effects of PALs in the GHG Step 3 Rule, including the benefits of 
GHG PALs. See 77 FR 41059-60. EPA is therefore proposing to approve the 
changes to the PAL provisions into the Alabama SIP, as amended in the 
August 23, 2016 submittal discussed below.

B. Alabama's August 23, 2016 Submittal

    Alabama's August 23, 2016 SIP submittal makes further changes to 
the State's PSD permitting regulation at Rule 335-3-14-.04. This 
submittal revises the GHG PALs threshold in Rule 335-3-14-.04(23)(b)4 
proposed in the May 8, 2013, submittal from 100,000 tpy to 75,000 tpy, 
as mentioned in section III.A above.\8\ The SIP submittal also revises 
the applicability of PSD for GHGs by removing language regulating GHG-
only (i.e., Step 2) sources in Rules 335-3-14-.04(1)(k) and 335-3-
14-.04(2)(a) to align with current federal requirements, as discussed 
below.
---------------------------------------------------------------------------

    \8\ As discussed in Section I, above, EPA is not acting on the 
remaining portions of this submittal. The submittal also withdraws 
the change proposed to Rule 335-3-14-.04(2)(zz) in the State's May 
8, 2013 SIP submittal to address the Biomass Deferral Rule.
---------------------------------------------------------------------------

    Alabama modifies its applicability language for GHGs to regulate 
only ``anyway'' sources. The State revises Rule 335-3-14-.04(1)(k) in 
its PSD applicability regulations and the definition of ``Major 
Stationary Source'' at Rule 335-3-14-.04(2)(a) by removing language 
that would subject a source to PSD requirements through GHG emissions 
alone. The proposed revision to subparagraph (2)(a) removes the 
following text from the definition of ``major stationary source'': 
``(iii) For GHGs, any stationary source which emits or has the 
potential to emit: (I) GHGs on a total mass rate in accordance with 
either subparagraph 2(a)1. or (2)(a)1.(i), and (II) GHGs of 100,000 
tons per year or more CO2e.'' The proposed revision to Rule 
335-3-14-.04(1)(k) replaces subparagraph (k) with the following text:

    (k) Greenhouse gases (GHGs)
    1. GHGs, as defined in Subparagraph (2)(zz) of this Rule,\9\ 
shall not be utilized in determining if a source is a major 
stationary source, as defined in Subparagraph (2)(a) of this Rule, 
or in determining if a modification is a major modification, as 
defined in Subparagraph (2)(b) of this Rule.
---------------------------------------------------------------------------

    \9\ Subparagraph (2)(zz) defines ``greenhouse gases'' as ``the 
aggregate of: Carbon dioxide, nitrous oxide, methane, 
hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride.''
---------------------------------------------------------------------------

    2. GHGs shall only be subject to the requirements of this Rule 
if:
    (i) A new major stationary source or major modification causes a 
significant emissions increase of GHGs, as defined in subparagraph 
(2)(mm) of this rule,\10\ and a significant net emissions increase 
of GHGs, as defined in subparagraphs (2)(c) and (2)(w) of this 
rule,\11\ and
---------------------------------------------------------------------------

    \10\ Pursuant to subparagraph (2)(mm), ``significant emissions 
increase means, for a regulated NSR pollutant, an increase in 
emissions that is significant (as defined in subparagraph (2)(w) of 
this rule) for that pollutant.''
    \11\ As it relates to GHGs, subparagraph (2)(w) defines 
``significant,'' in reference to a net emissions increase or 
potential to emit, at a rate of 75,000 tpy of GHGs on a CO2e basis. 
This definition of ``significant'' was previously approved by EPA on 
December 29, 2010. See 75 FR 81863.
---------------------------------------------------------------------------

    (ii) The new major stationary source or major modification is 
required to obtain a permit subject to the requirements of this Rule 
as a result of emissions of regulated NSR pollutants other than 
GHGs.

    Although these proposed changes to the Alabama SIP are structured 
differently than EPA's federal rules, the primary practical effect of 
both is the same: PSD requirements do not apply to GHG emissions from 
an ``anyway source'' unless the source emits GHGs at or above the 
75,000 tpy CO2e threshold.
    EPA has preliminarily concluded that proposing approval of these 
change into the SIP will not interfere with any applicable requirement 
concerning attainment and reasonable further progress (as defined in 
section 171), or any other applicable requirement of the CAA. Step 2 of 
the GHG Tailoring Rule was invalidated. As mentioned above, EPA 
discussed the effects of PALs in the 2002 Supplemental Analysis and the 
GHG Step 3 Rule.

IV. Incorporation by Reference

    In accordance with requirements of 1 CFR 51.5, EPA is proposing the 
incorporation by reference of ADEM Administrative Code Rules 335-3-
14-.04(1)(k), 335-3-14-.04(2)(a)(ii), and 335-3-14-.04(b)4, state 
effective on November 25, 2014. Therefore, EPA is proposing approval 
for inclusion of these materials in Alabama's State implementation 
plan. Once final, and these materials have been incorporated

[[Page 38664]]

by reference by EPA into that plan, they are fully Federally 
enforceable under sections 110 and 113 of the CAA as of the effective 
date of the final rulemaking of EPA's approval, and will be 
incorporated by reference by the Director of the Federal Register in 
the next update to the SIP compilation.\12\ EPA has made, and will 
continue to make, these materials generally available through 
www.regulations.gov and/or at the EPA Region 4 Office (please contact 
the person identified in the ``For Further Information Contact'' 
section of this preamble for more information).
---------------------------------------------------------------------------

    \12\ See 62 FR 27968 (May 22, 1997).
---------------------------------------------------------------------------

V. Proposed Action

    EPA is proposing to approve the portions of Alabama's May 8, 2013 
and August 23, 2016 SIP submittals that revise the PSD permitting 
program at Rule 335-3-14-.04--``Air Permits Authorizing Construction in 
Clean Areas (Prevention of Significant Deterioration (PSD))'' by 
removing language regulating GHG-only (i.e., Step 2) sources and by 
adding language to the PAL provisions. EPA believes that these changes 
are consistent with the requirements of the CAA.

VI. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
proposed action merely proposes to approve state law as meeting Federal 
requirements and does not impose additional requirements beyond those

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.);

uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Public Law 104-4);

     is not subject to requirements of Section 12(d) of the
