Approval and Promulgation of Implementation Plans; Washington: 
Interstate Transport of Fine Particulate Matter

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.

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

SUMMARY: The Clean Air Act (CAA) requires each State Implementation 
Plan (SIP) to contain adequate provisions prohibiting air emissions 
that will have certain adverse air quality effects in other states. On 
May 11, 2015, the State of Washington submitted a SIP revision to the 
Environmental Protection Agency (EPA) to address these interstate 
transport requirements with respect to the 2006 24-hour fine 
particulate matter (PM2.5) National Ambient Air Quality 
Standards (NAAQS). The EPA is proposing to find that Washington has 
adequately addressed certain CAA interstate transport requirements for 
the 2006 24-hour PM2.5 NAAQS.

I. Background

A. 2006 24-Hour PM2.5 NAAQS and Interstate Transport

    On September 21, 2006, the EPA promulgated a final rule revising 
the 1997 24-hour primary and secondary NAAQS for PM2.5 from 
65 micrograms per cubic meter ([micro]g/m\3\) to 35 [micro]g/m\3\ 
(October 17, 2006, 71 FR 61144). Section 110(a)(1) of the CAA requires 
each state to submit to the EPA, within three years (or such shorter 
period as the Administrator may prescribe) after the promulgation of a 
primary or secondary NAAQS or any revision thereof, a SIP that provides 
for the ``implementation, maintenance, and enforcement'' of such NAAQS. 
The EPA refers to these specific submittals as ``infrastructure'' SIPs 
because they are intended to address basic structural SIP requirements 
for new or revised NAAQS. For the 2006 24-hour PM2.5 NAAQS, 
these infrastructure SIPs were due on September 21, 2009. CAA section 
110(a)(2) includes a list of specific elements that ``[e]ach such plan 
submission'' must meet.
    The interstate transport provisions in CAA section 110(a)(2)(D)(i) 
(also called ``good neighbor'' provisions) require each state to submit 
a SIP that prohibits emissions that will have certain adverse air 
quality effects in other states. CAA section 110(a)(2)(D)(i) identifies 
four distinct elements related to the impacts of air pollutants 
transported across state lines. In this action, the EPA is addressing 
the first two elements of this section, specified at CAA section 
110(a)(2)(D)(i)(I),\1\ for the 2006 24-hour PM2.5 NAAQS.
---------------------------------------------------------------------------

    \1\ This proposed action does not address the two elements of 
the interstate transport SIP provision in CAA section 
110(a)(2)(D)(i)(II) regarding interference with measures required to 
prevent significant deterioration of air quality or to protect 
visibility in another state. We previously addressed CAA section 
110(a)(2)(D)(I)(II) for the 2006 24-hour PM2.5 NAAQS in a 
final action dated May 12, 2015 (80 FR 27102).
---------------------------------------------------------------------------

    The first element of CAA section 110(a)(2)(D)(i)(I) requires that 
each SIP for a new or revised NAAQS contain adequate provisions to 
prohibit any source or other type of emissions activity within the 
state from emitting air pollutants that will ``contribute significantly 
to nonattainment'' of the NAAQS in another state. The second element of 
CAA section 110(a)(2)(D)(i)(I) requires that each SIP contain adequate 
provisions to prohibit any source or other type of emissions activity 
in the state from emitting air pollutants that will ``interfere with 
maintenance'' of the applicable NAAQS in any other state.

B. Rules Addressing Interstate Transport for the 2006 24-hour 
PM2.5 NAAQS

    The EPA has addressed the interstate transport requirements of CAA 
section 110(a)(2)(D)(i)(I) in past regulatory actions.\2\ The EPA 
promulgated the final Cross-State Air Pollution Rule (Transport Rule) 
to address CAA section 110(a)(2)(D)(i)(I) in the eastern portion of the 
United States with respect to the 2006 PM2.5 NAAQS, the 1997 
PM2.5 NAAQS, and the 1997 8-hour ozone NAAQS (August 8, 
2011, 76 FR 48208). The Transport Rule was intended to replace the 
earlier Clean Air Interstate Rule (CAIR) which was judicially 
remanded.\3\ See North Carolina v. EPA, 531 F.3d 896 (D.C. Cir. 2008). 
On August 21, 2012, the U.S. Court of Appeals for the DC Circuit issued 
a decision vacating the Transport Rule. See EME Homer City Generation, 
L.P. v. E.P.A., 696 F.3d 7 (D.C. Cir. 2012). The Court also ordered the 
EPA to continue implementing CAIR in the interim. However, on April 29, 
2014, the U.S. Supreme Court reversed and remanded the DC Circuit's 
ruling and upheld the EPA's approach in the Transport Rule for the 
issues that were in front of the Supreme Court for review.\4\ On 
October 23, 2014, the DC Circuit lifted the stay on the Transport 
Rule.\5\ While our evaluation is consistent with the Transport Rule 
approach, the State of Washington was not covered by either

[[Page 32872]]

CAIR or the Transport Rule, and the EPA made no determinations in 
either rule regarding whether emissions from sources in Washington 
significantly contribute to nonattainment or interfere with maintenance 
of the 2006 24-hour PM2.5 NAAQS in another state, nor did it 
attempt to quantify Washington's obligation.\6\
---------------------------------------------------------------------------

    \2\ See NOX SIP Call, 63 FR 57371 (October 27, 1998); 
Clean Air Interstate Rule (CAIR), 70 FR 25172 (May 12, 2005); and 
Transport Rule or Cross-State Air Pollution Rule, 76 FR 48208 
(August 8, 2011).
    \3\ CAIR addressed the 1997 annual and 24-hour PM2.5 
NAAQS, and the 1997 8-hour ozone NAAQS. It did not address the 2006 
24-hour PM2.5 NAAQS. For more information on CAIR, please 
see our July 30, 2012 proposal for Arizona regarding interstate 
transport for the 2006 PM2.5 NAAQS (77 FR 44551, 44552).

C. Guidance

    On September 25, 2009, the EPA issued a guidance memorandum that 
addressed the requirements of CAA section 110(a)(2)(D)(i) for the 2006 
24-hour PM2.5 NAAQS (``2006 24-hour PM2.5 NAAQS 
Infrastructure Guidance'' or ``Guidance'').\7\ With respect to the 
requirement in CAA section 110(a)(2)(D)(i)(I) that state SIPs contain 
adequate provisions prohibiting emissions that would contribute 
significantly to nonattainment of the NAAQS in any other state, the 
2006 24-hour PM2.5 NAAQS Infrastructure Guidance essentially 
reiterated the recommendations for western states made by the EPA in 
previous guidance addressing the CAA section 110(a)(2)(D)(i) 
requirements for the 1997 8-hour ozone and 1997 PM2.5 
NAAQS.\8\ The 2006 24-hour PM2.5 NAAQS Infrastructure 
Guidance advised states outside of the CAIR region to include in their 
CAA section 110(a)(2)(D)(i)(I) SIPs adequate technical analyses to 
support their conclusions regarding interstate pollution transport, 
e.g., information concerning emissions in the state, meteorological 
conditions in the state and in potentially impacted states, monitored 
ambient pollutant concentrations in the state and in potentially 
impacted states, distances to the nearest areas not attaining the NAAQS 
in other states, and air quality modeling.\9\ With respect to the 
requirement in CAA section 110(a)(2)(D)(i)(I) that state SIPs contain 
adequate provisions prohibiting emissions that would interfere with 
maintenance of the NAAQS by any other state, the Guidance stated that 
SIP submissions must address this independent requirement of the 
statute and provide technical information appropriate to support the 
state's conclusions, such as information concerning emissions in the 
state, meteorological conditions in the state and in potentially 
impacted states, monitored ambient concentrations in the state and in 
potentially impacted states, and air quality modeling. See footnotes 5 
and 6.
---------------------------------------------------------------------------

    \7\ See Memorandum from William T. Harnett entitled ``Guidance 
on SIP Elements Required Under Sections 110(a)(1) and (2) for the 
2006 24-Hour Fine Particle (PM2.5) National Ambient Air 
Quality Standards (NAAQS),'' September 25, 2009, available at http://www.epa.gov/ttn/caaa/t1/memoranda/20090925_harnett_pm25_sip_110a12.pdf.
    \8\ See Memorandum from William T. Harnett entitled ``Guidance 
for State Implementation Plan (SIP) Submission to Meet Current 
Outstanding Obligations Under Section 110(a)(2)(D)(i) for the 8-hour 
ozone and PM2.5 National Ambient Air Quality Standards,'' 
August 15, 2006, available at http://www.epa.gov/ttn/caaa/t1/memoranda/section110a2di_sip_guidance.pdf.
    \9\ The 2006 24-hour PM2.5 NAAQS Infrastructure 
Guidance stated that EPA was working on a new rule to replace CAIR 
that would address issues raised by the Court in the North Carolina 
case and that would provide guidance to states in addressing the 
requirements related to interstate transport in CAA section 
110(a)(2)(D)(i)(I) for the 2006 24-hour PM2.5 NAAQS. It 
also noted that states could not rely on the CAIR rule for section 
110(a)(2)(D)(i)(I) submissions for the 2006 24-hour PM2.5 
NAAQS because the CAIR rule did not address this NAAQS. See 2006 
PM2.5 NAAQS Infrastructure Guidance at 4.
---------------------------------------------------------------------------

    In this action, the EPA is proposing to use the conceptual approach 
to evaluating interstate pollution transport under CAA section 
110(a)(2)(D)(i)(I) for the 2006 24-hour PM2.5 NAAQS with 
respect to Washington that the EPA explained in the 2006 24-hour 
PM2.5 NAAQS Infrastructure Guidance. The EPA believes that 
the CAA section 110(a)(2)(D)(i)(I) SIP submission from Washington for 
the 2006 24-hour PM2.5 NAAQS may be evaluated using a 
``weight of the evidence'' approach that takes into account available 
relevant information. Such information may include, but is not limited 
to, the amount of emissions in the state relevant to the 2006 24-hour 
PM2.5 NAAQS, the meteorological conditions in the area, the 
distance from the state to the nearest monitors in other states that 
are appropriate receptors, or such other information as may be 
probative to consider whether sources in the state may contribute 
significantly to nonattainment or interfere with maintenance of the 
2006 24-hour PM2.5 NAAQS in other states. These submissions 
may rely on modeling when acceptable modeling technical analyses are 
available, but if not available, other available information can be 
sufficient to evaluate the presence or degree of interstate transport 
in a specific situation for the 2006 24-hour PM2.5 NAAQS. 
For further explanation of this approach, see the technical support 
document (TSD) in the docket for this action.

II. State Submittal

    CAA sections 110(a)(1) and (2) and section 110(l) require that 
revisions to a SIP be adopted by the state after reasonable notice and 
public hearing. The EPA has promulgated specific procedural 
requirements for SIP revisions in 40 CFR part 51, subpart F. These 
requirements include publication of notices, by prominent advertisement 
in the relevant geographic area, a public comment period of at least 30 
days, and an opportunity for a public hearing.
    On May 11, 2015, Washington submitted a SIP to address the 
interstate transport requirements of CAA section 110(a)(2)(D)(i) for 
the 2006 PM2.5 NAAQS (Washington 2006 PM2.5 
Interstate Transport submittal).\10\ The Washington 2006 
PM2.5 Interstate Transport submittal included documentation 
of a public comment period from March 9, 2015 through April 10, 2015, 
and opportunity for public hearing. We find that the process followed 
by Washington in adopting the SIP submittal complies with the 
procedural requirements for SIP revisions under CAA section 110 and the 
EPA's implementing regulations.
---------------------------------------------------------------------------

    \10\ The Washington 2006 PM2.5 Interstate Transport 
submittal only addressed the CAA section 110(a)(2)(D)(i)(I) 
interstate transport requirements of the 2006 PM2.5 
NAAQS. The EPA previously addressed CAA section 110(a)(2)(D)(i)(II) 
for the 2006 PM2.5 NAAQS in a separate action (May 12, 
2015, 80 FR 27102). In addition, we previously approved the 
Washington SIP for 110(a)(2)(D)(i) with respect to the 1997 
PM2.5 NAAQS on January 13, 2009 (74 FR 1591). Finally, 
Washington did not submit a CAA section 110(a)(2)(D)(i)(I) 
demonstration with respect to the 2012 PM2.5 NAAQS, which 
the State intends to address in a future action.
---------------------------------------------------------------------------

    With respect to the requirement in CAA section 110(a)(2)(D)(i)(I), 
the Washington 2006 PM2.5 Interstate Transport submittal 
referred to the applicable rules in the Washington SIP, meteorological 
and other characteristics of areas with nonattainment problems for the 
2006 24-hour PM2.5 NAAQS in surrounding states, and 
Interagency Monitoring of Protected Visual Environments (IMPROVE) data 
from the regional haze program that provides additional information on 
how Washington sources influence monitored PM2.5 levels in 
National Parks and wilderness areas surrounding Washington to assess 
potential interstate transport. The Washington submittal concluded 
that, based on the weight of the evidence, the Washington SIP 
adequately addresses the interstate transport requirements of CAA 
section 110(a)(2)(D)(i)(I) for the 2006 24-hour PM2.5 NAAQS. 
A detailed discussion of the Washington 2006 PM2.5 
Interstate Transport submittal can be found in the technical support 
document (TSD) in the docket for this action.

III. EPA Evaluation

    To determine whether the CAA section 110(a)(2)(D)(i)(I) 
requirements

[[Page 32873]]

are satisfied, the EPA must determine whether a state's emissions will 
contribute significantly to nonattainment or interfere with maintenance 
in other states. If this factual finding is in the negative, then CAA 
section 110(a)(2)(D)(i)(I) does not require any changes to a state's 
SIP. Consistent with the EPA's approach in the 1998 NOX SIP 
call, the 2005 CAIR, and the 2011 Transport Rule, the EPA is evaluating 
these impacts with respect to specific monitors identified as having 
nonattainment and/or maintenance problems, which we refer to as 
``receptors.'' See footnote 2.
    With respect to this proposed action, the EPA notes that no single 
piece of information is by itself dispositive of the issue. Instead, 
the total weight of all the evidence taken together is used to evaluate 
significant contributions to nonattainment or interference with 
maintenance of the 2006 24-hour PM2.5 NAAQS in another 
state. Our proposed action takes into account the Washington 2006 
PM2.5 Interstate Transport submittal, a supplemental 
evaluation of monitors in other states that are appropriate 
``nonattainment receptors'' or ``maintenance receptors,'' and a review 
of monitoring data considered representative of background. Based on 
the analysis in our TSD in the docket for this action, we believe that 
it is reasonable to conclude that emissions from sources in Washington 
do not significantly contribute to nonattainment or interfere with 
maintenance of the 2006 24-hour PM2.5 NAAQS in any other 
state.

A. Identification of Nonattainment and Maintenance Receptors

    The EPA evaluated data from existing monitors over three 
overlapping three-year periods (i.e., 2009-2011, 2010-2012, and 2011-
2013) to determine which areas were violating the 2006 24-hour 
PM2.5 NAAQS and which areas might have difficulty 
maintaining the standard. If a monitoring site measured a violation of 
the 2006 24-hour PM2.5 NAAQS during the most recent three-
year period (2011-2013), then this monitor location was evaluated for 
purposes of the significant contribution to nonattainment element of 
CAA section 110(a)(2)(D)(i)(I). If, on the other hand, a monitoring 
site showed attainment of the 2006 24-hour PM2.5 NAAQS 
during the most recent three-year period (2011-2013) but a violation in 
at least one of the previous two three-year periods (2009-2011 or 2010-
2012), then this monitor location was evaluated for purposes of the 
interference with maintenance element of the statute.
    The State of Washington was not covered by the modeling analyses 
available for the CAIR and the Transport Rule. The approach described 
above is similar to the approach utilized by the EPA in promulgating 
the CAIR and the Transport Rule. By this method, the EPA has identified 
those areas with monitors to be considered ``nonattainment receptors'' 
or ``maintenance receptors'' for evaluating whether the emissions from 
sources in another state could significantly contribute to 
nonattainment in, or interfere with maintenance in, that particular 
area.

B. Evaluation of Significant Contribution to Nonattainment

    The EPA reviewed the Washington 2006 PM2.5 Interstate 
Transport submittal and additional technical information to evaluate 
the potential for emissions from sources in Washington to contribute 
significantly to nonattainment of the 2006 24-hour PM2.5 
NAAQS at specified monitoring sites in the western United States.\11\ 
The EPA first identified as ``nonattainment receptors'' all monitoring 
sites in the western states that had recorded PM2.5 design 
values above the level of the 2006 24-hour PM2.5 NAAQS (35 
[mu]g/m\3\) during the years 2011-2013.\12\ Please see the TSD in the 
docket for a more detailed description of the EPA's methodology for 
selection of nonattainment receptors. All of the nonattainment 
receptors we identified in western states are in California, Idaho, 
Montana, Oregon, and Utah.\13\
---------------------------------------------------------------------------

    \11\ The EPA has also considered potential PM2.5 
transport from Washington to the nearest nonattainment and 
maintenance receptors located in the eastern, midwestern, and 
southern states covered by the Transport Rule and believes it is 
reasonable to conclude that, given the significant distance from 
Washington to the nearest such receptor (in Illinois) and the 
relatively insignificant amount of emissions from Washington that 
could potentially be transported such a distance, emissions from 
Washington sources do not significantly contribute to nonattainment 
or interfere with maintenance of the 2006 24-hour PM2.5 
NAAQS at this location. These same factors also support a finding 
that emissions from Washington sources neither contribute 
significantly to nonattainment nor interfere with maintenance of the 
2006 24-hour PM2.5 NAAQS at any location further east. 
See TSD at Section II.C.
    \12\ Because CAIR did not cover states in the western United 
States, these data are not significantly impacted by the remanded 
CAIR at the time and thus could be considered in this analysis.
    \13\ As this analysis is focused on interstate transport, the 
EPA did not evaluate the impact of Washington emissions on 
nonattainment or maintenance receptors within Washington.
---------------------------------------------------------------------------

    Based on the analysis in our TSD, we believe it is reasonable to 
conclude that emissions from sources in Washington do not significantly 
contribute to nonattainment of the 2006 24-hour PM2.5 NAAQS 
in any other western state. We also evaluated nonattainment receptors 
in eastern states, as detailed in the TSD, and we believe it is 
reasonable to conclude that emissions from sources in Washington do not 
significantly contribute to nonattainment of the 2006 24-hour 
PM2.5 NAAQS in any eastern state. Based on the analysis in 
our TSD, we are proposing to determine that Washington's SIP adequately 
addresses the requirements of CAA section 110(a)(2)(D)(i)(I) for the 
2006 24-hour PM2.5 NAAQS.

C. Evaluation of Interference With Maintenance

    The EPA reviewed the Washington 2006 PM2.5 Interstate 
Transport SIP and additional technical information to evaluate the 
potential for Washington emissions to interfere with maintenance of the 
2006 24-hour PM2.5 NAAQS at specified monitoring sites in 
the western United States. The EPA first identified as ``maintenance 
receptors'' all monitoring sites in the western states that had 
recorded PM2.5 design values above the level of the 2006 24-
hour PM2.5 NAAQS (35 [mu]g/m\3\) during the 2009-2011 and/or 
2010-2012 periods but below this standard during the 2011-2013 period. 
Please see our TSD for more information regarding the EPA's methodology 
for selection of maintenance receptors. All of the maintenance 
receptors we identified in western states are located in California, 
Montana, and Utah.
    As detailed in the TSD, we believe it is reasonable to conclude 
that emissions from sources in Washington do not interfere with 
maintenance of the 2006 24-hour PM2.5 NAAQS in these states. 
We also evaluated maintenance receptors in eastern states, as detailed 
in the TSD, and we believe it is reasonable to conclude that emissions 
from sources in Washington do not interfere with maintenance of the 
2006 24-hour PM2.5 NAAQS in any eastern state.

IV. Proposed Action

    The EPA is proposing to find that Washington has adequately 
addressed the interstate transport requirements of CAA section 
110(a)(2)(D)(i)(I) for the 2006 24-hour PM2.5 NAAQS.

V. 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

[[Page 32874]]

the CAA. Accordingly, this 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 
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) 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

     is not a significant regulatory action subject to

     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 it 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).
    The SIP is not approved to apply on any Indian reservation land in 
Washington except for as specifically noted below and is also not 
approved to apply 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). Washington's SIP is approved to apply on non-trust land within 
the exterior boundaries of the Puyallup Indian Reservation, also known 
as the 1873 Survey Area. Under the Puyallup Tribe of Indians Settlement 
Act of 1989, 25 U.S.C. 1773, Congress explicitly provided state and 
local agencies in Washington authority over activities on non-trust 
lands within the 1873 Survey Area.
