40 CFR Part 52

[EPA-R09-OAR-2015-0204; FRL-9969-02--Region 9]

Approval and Promulgation of Implementation Plans; California; 
South Coast Moderate Area Plan for the 2006 PM2.5 Standards; 
Correction of Deficiency

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve California's Reasonably Available Control Measures/Reasonably 
Available Control Technology and Reasonable Further Progress 
demonstrations for the 2006 24-hour fine particulate matter 
(PM2.5) National Ambient Air Quality Standards (NAAQS or 
``standards'') in the Los Angeles-South Coast nonattainment area and to 
determine that the State has corrected the deficiency that formed the 
basis for the prior partial disapproval of the Moderate Area Plan 
submitted for these NAAQS. The proposed determination is based on the 
EPA's final approval of revisions to the South Coast Air Quality 
Management District's Regional Clean Air Incentives Market (RECLAIM) 
program and 2016 Reasonably Available Control Technology (RACT) 
Demonstration. If today's action is finalized as proposed, the 
sanctions clocks triggered by the partial disapproval will be 
terminated.

I. Background

    On October 17, 2006, the EPA revised the 24-hour NAAQS for 
PM2.5, particulate matter with a diameter of 2.5 microns or 
less or ``fine particles,'' to provide increased protection of public 
health by lowering its level from 65 micrograms per cubic meter 
([micro]g/m\3\) to 35 [micro]g/m\3\ (40 CFR 50.13). Epidemiological 
studies have shown statistically significant correlations between 
elevated PM2.5 levels and premature mortality. Other 
important health effects associated with PM2.5 exposure 
include aggravation of respiratory and cardiovascular disease (as 
indicated by increased hospital admissions, emergency room visits, 
absences from school or work, and restricted activity days), changes in 
lung function and increased respiratory symptoms. Individuals 
particularly sensitive to PM2.5 exposure include older 
adults, people with heart and lung disease, and children (78 FR 3086 at 
3088, January 15, 2013). Fine particles can be emitted directly into 
the atmosphere as a solid or liquid particle or can be formed in the 
atmosphere as a result of various chemical reactions among precursor 
pollutants such as nitrogen oxides, sulfur oxides, volatile organic 
compounds, and ammonia.
    Following promulgation of a new or revised NAAQS, section 107(d) of 
the CAA requires the EPA to designate areas throughout the nation as 
attaining or not attaining the NAAQS. On November 13, 2009, the EPA 
designated the Los Angeles-South Coast Air Basin (``South Coast'') as 
nonattainment for the 2006 24-hour PM2.5 NAAQS of 35 
[micro]g/m3 (74 FR 58688). This designation became effective 
on December 14, 2009 (40 CFR 81.305). The South Coast nonattainment 
area is also designated nonattainment for the 1997 annual and 24-hour 
PM2.5 NAAQS and the 2012 annual PM2.5 NAAQS. 
Today's proposed action addresses only requirements for the 2006 24-
hour PM2.5 NAAQS in the South Coast nonattainment area.
    On February 13, 2013 and March 4, 2015, California submitted SIP 
revisions to address planning requirements for the 2006 
PM2.5 NAAQS in the South Coast nonattainment area. We refer 
to these submissions collectively as the ``2012 PM2.5 Plan'' 
or ``Plan.'' On April 14, 2016, we finalized a partial approval and 
partial disapproval of the 2012 PM2.5 Plan (81 FR 22025). 
Our partial disapproval of the 2012 PM2.5 Plan was based on 
deficiencies in the Plan with respect to the Reasonably Available 
Control Measures/Reasonably Available Control Technology (RACM/RACT) 
and Reasonable Further Progress (RFP) requirements. Specifically, we 
found that the 2012 PM2.5 Plan failed to satisfy the RACM/
RACT requirement in CAA sections 172(c)(1) and 189(a)(1)(C) because it 
did not provide a demonstration that the South Coast Air Quality 
Management District's (SCAQMD or ``District'') nitrogen oxides (NOX) 
RECLAIM program ensures that the level of NOX emissions reductions 
resulting from the RECLAIM program is equivalent, in the aggregate, to 
those NOX emissions reductions expected from the direct application of 
RACT on all covered sources within the South Coast nonattainment area. 
We also found that the Plan failed to meet the requirement for RFP in 
CAA section 172(c)(2) because the deficiency with respect to RACM/RACT 
also meant that the State was not implementing all RACM/RACT as 
expeditiously as practicable. We noted in our final action on the 2012 
PM2.5 Plan that the State could remedy these deficiencies by 
submitting revisions to the NOX RECLAIM program together with 
documentation sufficient to demonstrate that the revised program 
ensures, in the aggregate, NOX emission reductions equivalent to RACT-
level controls for all covered facilities (81 FR at 22028, 22029).
    Our April 14, 2016 partial disapproval of the 2012 PM2.5 
Plan became effective on May 16, 2016, and started a sanctions clock 
for imposition of offset sanctions 18 months after May 16, 2016, and 
highway sanctions 6 months later, pursuant to CAA section 179 and our 
regulations at 40 CFR 52.31. Accordingly, offset sanctions will apply 
on November 16, 2017, and highway sanctions will apply on May 16, 2018, 
unless the EPA determines that the State has corrected the deficiency 
forming the basis of the disapproval.
    On March 17, 2017, the California Air Resources Board (CARB) 
submitted a SIP revision consisting of a series of amendments to the 
SCAQMD's NOX RECLAIM program. The submittal was intended to strengthen 
the program and correct the deficiencies identified in both the EPA's 
partial disapproval of the 2012 PM2.5 Plan (81 FR 22025, 
April 14, 2016) and in the EPA's separate proposal to partially 
disapprove the SCAQMD's ``2016 AQMP Reasonably Available Control 
Technology (RACT) Demonstration'' (``2016 AQMP RACT SIP'') (81 FR 
76547, November 3, 2016). Additionally, on May 22, 2017, CARB submitted 
the District's public draft version of the ``Supplemental RACM/RACT 
Analysis for the 2006 24-Hour PM2.5 and 2008 8-Hour Ozone 
Standards'' (``2017 RACT Supplement'') to address these same 
deficiencies. On June 6, 2017, the EPA proposed to approve the 
submitted NOX RECLAIM program amendments as satisfying general CAA 
requirements for SIP revisions (82 FR 25996). The EPA finalized this 
action on September 14, 2017 (82 FR 43176). On June 15, 2017, the EPA 
proposed to approve the 2016 AQMP RACT SIP and the 2017 RACT Supplement 
as satisfying the RACT requirements of CAA sections 182(b) and (f) and 
40 CFR 51.1112 for the South Coast and Coachella Valley nonattainment 
areas for the 2008 ozone NAAQS (82 FR 27451). The EPA finalized this 
action on September 20, 2017 (82 FR 43850).\1\
---------------------------------------------------------------------------

    \1\ CARB submitted the final ``Supplemental RACM/RACT Analysis 
for the 2006 24-Hour PM2.5 and 2008 8-Hour Ozone 
Standards'' (``2017 RACT Supplement'') on July 27, 2017. See letter 
dated July 27, 2017, from Richard Corey, Executive Officer, CARB, to 
Alexis Strauss, Acting Regional Administrator, EPA Region IX.
---------------------------------------------------------------------------

II. Proposed Action

    We are proposing to determine that the RECLAIM program amendments 
submitted by CARB on March 17, 2017, and the 2017 RACT Supplement 
submitted by CARB on May 22, 2017, together correct the deficiency in 
the RACM/RACT element of the 2012 PM2.5 Plan that had 
provided the basis for the EPA's prior partial disapproval of the Plan. 
As explained in our June 6, 2017 proposed action on the RECLAIM program 
amendments, the revised program lowers the NOX emission cap 
in the RECLAIM program and establishes requirements for removing 
RECLAIM trading credits (RTCs) from

[[Page 46953]]

the trading market to prevent NOX RTCs associated with 
facilities that have shut down from entering the RECLAIM market and 
potentially delaying the installation of pollution controls at other 
facilities (82 FR 25996, 25998, June 6, 2017). These revisions to the 
RECLAIM program strengthen the SIP by requiring major NOX 
emission sources covered by the program to collectively achieve 
additional emission reductions,\2\ and were fully approved into the 
California SIP on September 14, 2017 (see 82 FR 43176). Additionally, 
as explained in our June 15, 2017 proposed action on the 2016 AQMP RACT 
SIP and 2017 RACT Supplement, the 2017 RACT Supplement contains the 
District's demonstration of how the SIP-approved RECLAIM program has 
achieved and continues to achieve, in the aggregate, RACT level of 
control for major NOX sources in the South Coast (82 FR at 
27454-27455, June 15, 2017).\3\ As part of our September 20, 2017 final 
approval of the 2016 AQMP RACT SIP and 2017 RACT Supplement, we 
concluded that major NOX sources covered by the RECLAIM 
program are now subject to RACT level control requirements (82 FR 
43850, 43856). Implementation of RACT-level control requirements at 
major NOX sources covered by the RECLAIM program satisfies 
the RACM/RACT requirement in CAA sections 172(c)(1) and 189(a)(1)(C) 
for these sources. We propose to determine that these SIP submissions 
correct the RACM/RACT deficiency that we identified in our partial 
disapproval of the 2012 PM2.5 Plan and to approve the RACM/
RACT demonstration in the Plan, as revised.
---------------------------------------------------------------------------

    \2\ The revisions to the RECLAIM program are projected to reduce 
NOX emissions by 12 tons per day by 2023. See SCAQMD, 
Summary Minutes of the Board of the South Coast Air Quality 
Management District, December 4, 2015, at 15; see also U.S. EPA, 
Region IX Air Division, ``Technical Support Document for EPA's 
Rulemaking for the California State Implementation Plan, South Coast 
Air Quality Management District Regional Clean Air Incentives Market 
Program Rules,'' May 2017, at 9, 10.
    \3\ For more information on our evaluation of the RECLAIM 
program in accordance with CAA RACT requirements, see the Technical 
Support Document accompanying our June 15, 2017 proposed rule (82 FR 
27451) and our responses to comments on that proposal (82 FR 43856, 
September 20, 2017).
---------------------------------------------------------------------------

    In addition, we are proposing to determine that these SIP 
submissions correct the RFP deficiency that we identified in our 
partial disapproval of the Plan. Our partial disapproval of the 2012 
PM2.5 Plan for failure to satisfy the RFP requirement in CAA 
section 172(c)(2) was predicated on our disapproval of the Plan with 
respect to the RACM/RACT requirement (81 FR at 22028, April 14, 2016). 
The Plan, as revised, demonstrates that the State is now implementing 
RACM/RACT for NOX from covered sources in the South Coast 
nonattainment area. Therefore, based on our proposal to determine that 
the State has corrected the RACM/RACT deficiency, we also propose to 
determine that the State has corrected the RFP deficiency that we 
identified in our partial disapproval of the 2012 PM2.5 Plan 
and to approve the RFP demonstration in the Plan, as revised.
    If finalized as proposed, these determinations will permanently 
stop the sanctions clocks triggered by our April 14, 2016 partial 
disapproval of the 2012 PM2.5 Plan.

III. Request for Public Comment

    We will accept comments from the public on this proposal for the 
next 30 days. The deadline and instructions for submission of comments 
are provided in the DATES and ADDRESSES sections at the beginning of 
this preamble.

IV. Statutory and Executive Order Reviews

    Under the Clean Air Act, 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, the EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this proposed action merely proposes to approve state law 
as meeting federal requirements and does not impose additional 
requirements beyond those imposed by state law. For that reason, this 
proposed action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
     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 requirements of section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the Clean Air Act; and
     Does not provide the EPA with the discretionary authority 
to address disproportionate human health or environmental effects with 
practical, appropriate, and legally permissible methods under Executive 
Order 12898 (59 FR 7629, February 16, 1994).
    In addition, the SIP is not approved to apply on any Indian 
reservation land or in any other area where the EPA or an Indian tribe 
has demonstrated that a tribe has jurisdiction. In those areas of 
Indian country, the rule does not have tribal implications and will not 
impose substantial direct costs on tribal governments or preempt tribal 
law as specified by Executive Order 13175 (65 FR 67249, November 9, 
2000).
