SUPPLEMENTARY INFORMATION: For further information, please see the direct final action, of the same title, which is located in the Rules section of this Federal Register. The EPA is approving the State’s SIP revisions as a direct final rule without prior proposal because the EPA views this as a noncontroversial SIP action and anticipates no adverse comments. A detailed rationale for the approval is set forth in the preamble to the direct final rule. If the EPA receives no adverse comments, the EPA will not take further action on this proposed rule. If the EPA receives adverse comments, the EPA will withdraw the direct final rule and it will not take The Clean Air Act (CAA) requires each State Implementation Plan (SIP) to contain adequate provisions prohibiting emissions that will have certain adverse air quality effects in other states. On May 11, 2015, the State of Washington made a submittal to the Environmental Protection Agency (EPA) to address these requirements. The EPA is proposing to approve the submittal as meeting the requirement that each SIP contain adequate provisions to prohibit emissions that will contribute significantly to nonattainment or interfere with maintenance of the 2008 ozone National Ambient Air Quality Standard (NAAQS) in any other state.

FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: Throughout this document wherever ‘‘we,’’ ‘‘us,’’ or ‘‘our’’ is used, it is intended to refer to the EPA. Information is organized as follows: Table of Contents I. Background II. State Submittal III. EPA Evaluation IV. Proposed Action V. Statutory and Executive Order Reviews srobinson on DSK5SPTVN1PROD with PROPOSALS I. Background On March 12, 2008, the EPA revised the levels of the primary and secondary 8-hour ozone standards from 0.08 parts per million (ppm) to 0.075 ppm (73 FR 16436). The CAA requires states to submit, within three years after promulgation of a new or revised standard, SIPs meeting the applicable ‘‘infrastructure’’ elements of sections 110(a)(1) and (2). One of these applicable infrastructure elements, CAA section 110(a)(2)(D)(i), requires SIPs to contain ‘‘good neighbor’’ provisions to prohibit certain adverse air quality effects on neighboring states due to interstate transport of pollution. There are four sub-elements within CAA section 110(a)(2)(D)(i). This action addresses the first two sub-elements of the good neighbor provisions, at CAA section 110(a)(2)(D)(i)(I). These subelements require that each SIP for a new or revised standard 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’’ or ‘‘interfere with maintenance’’ of the applicable air quality standard in any other state. We note that the EPA has addressed the interstate transport requirements of CAA section 110(a)(2)(D)(i)(I) for the eastern portion of the United States in several past regulatory actions.1 We most recently promulgated the CrossState Air Pollution Rule (CSAPR), which addressed CAA section 110(a)(2)(D)(i)(I) in the eastern portion of the United States.2 CSAPR addressed multiple national ambient air quality 1 NO SIP Call, 63 FR 57371 (October 27, 1998); X Clean Air Interstate Rule (CAIR), 70 FR 25172 (May 12, 2005); Cross-State Air Pollution Rule (CSAPR), 76 FR 48208 (August 8, 2011). 2 76 FR 48208. VerDate Sep<11>2014 17:30 Oct 26, 2015 Jkt 238001 standards, but did not address the 2008 8-hour ozone standard.3 In CSAPR, the EPA used detailed air quality analyses to determine whether an eastern state’s contribution to downwind air quality problems was at or above specific thresholds. If a state’s contribution did not exceed the specified air quality screening threshold, the state was not considered ‘‘linked’’ to identified downwind nonattainment and maintenance receptors and was therefore not considered to significantly contribute to or interfere with maintenance of the standard in those downwind areas. If a state exceeded that threshold, the state’s emissions were further evaluated, taking into account both air quality and cost considerations, to determine what, if any, emissions reductions might be necessary. For the reasons stated below, we believe it is appropriate to use the same approach we used in CSAPR to establish an air quality screening threshold for the evaluation of interstate transport requirements for the 2008 ozone standard. In CSAPR, the EPA proposed an air quality screening threshold of one percent of the applicable NAAQS and requested comment on whether one percent was appropriate.4 The EPA evaluated the comments received and ultimately determined that one percent was an appropriately low threshold because there were important, even if relatively small, contributions to identified nonattainment and maintenance receptors from multiple upwind states. In response to commenters who advocated a higher or lower threshold than one percent, the EPA compiled the contribution modeling results for CSAPR to analyze the impact of different possible thresholds for the eastern United States. The EPA’s analysis showed that the onepercent threshold captures a high percentage of the total pollution transport affecting downwind states, while the use of higher thresholds would exclude increasingly larger percentages of total transport. For example, at a five percent threshold, the majority of interstate pollution transport affecting downwind receptors would be excluded.5 In addition, the EPA determined that it was important to use a relatively lower one-percent threshold because there are adverse health impacts associated with ambient ozone 3 CSAPR addressed the 1997 8-hour ozone, and the 1997 and 2006 fine particulate matter NAAQS. 4 CSAPR proposal, 75 FR 45210, 45237 (August 2, 2010). 5 See also Air Quality Modeling Final Rule Technical Support Document, Appendix F; Analysis of Contribution Thresholds. PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 65673 even at low levels.6 The EPA also determined that a lower threshold such as 0.5 percent would result in modest increases in the overall percentages of fine particulate matter and ozone pollution transport captured relative to the amounts captured at the one-percent level. The EPA determined that a ‘‘0.5 percent threshold could lead to emission reduction responsibilities in additional states that individually have a very small impact on those receptors— an indicator that emission controls in those states are likely to have a smaller air quality impact at the downwind receptor. We are not convinced that selecting a threshold below one percent is necessary or desirable.’’ 7 In the final CSAPR, the EPA determined that one percent was a reasonable choice considering the combined downwind impact of multiple upwind states in the eastern United States, the health effects of low levels of fine particulate matter and ozone pollution, and the EPA’s previous use of a one-percent threshold in CAIR. The EPA used a single ‘‘bright line’’ air quality threshold equal to one percent of the 1997 8-hour ozone standard, or 0.08 ppm.8 The projected contribution from each state was averaged over multiple days with projected high modeled ozone, and then compared to the onepercent threshold. We concluded that this approach for setting and applying the air quality threshold for ozone was appropriate because it provided a robust metric, was consistent with the approach for fine particulate matter used in CSAPR, and because it took into account, and would be applicable to, any future ozone standards below 0.08 ppm.9 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)(I) for the 2008 ozone NAAQS. The Washington submittal 6 CSAPR, 76 FR 48208, 48236–37 (August 8, 2011). 7 Id. 8 Id. 9 Id. E:\FR\FM\27OCP1.SGM 27OCP1 srobinson on DSK5SPTVN1PROD with PROPOSALS 65674 Federal Register / Vol. 80, No. 207 / Tuesday, October 27, 2015 / Proposed Rules 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 submittal complies with the procedural requirements for SIP revisions under CAA section 110 and the EPA’s implementing regulations. With respect to the requirements in CAA section 110(a)(2)(D)(i)(I), the Washington submittal referred to applicable rules in the Washington SIP, 2011 National Emissions Inventory (NEI) data, and modeling conducted by the State using the Motor Vehicle Emission Simulator (MOVES2014, database version 20141021). Washington noted that efforts by the EPA and states to address ozone transport have historically been focused on reductions of nitrogen oxides (NOX), a precursor to ozone formation, and provided 2011 NEI data for the major NOX emissions categories in the State. Washington found that on-road mobile sources comprise 57 percent of total NOX emissions, non-road mobile sources represent 11 percent, and the third largest group, point sources, comprises 9 percent of all Washington NOX emissions in 2011. Washington then performed MOVES2014 modeling to look specifically at past and future trends in on-road and non-road mobile sources, the two largest source categories in Washington, for the years 2000 through 2020. The MOVES2014 modeling showed sustained, continuous reductions in NOX emissions from approximately 800 tons per day in 2000 to approximately 250 tons per day projected in 2020. Based on this evidence, and the EPA’s draft photochemical air quality modeling data available at the time of Washington’s submission, the State concluded that emissions of ozone precursors from Washington sources will not significantly contribute to nonattainment or interfere with maintenance of the 2008 ozone NAAQS in any other state.10 The Washington submittal provided further information to support this conclusion by citing the stationary source permitting regulations approved into the Washington SIP that require new sources and modifications to protect the ambient air quality standards, including the 2008 ozone 10 See Memorandum from Stephen D. Page entitled ‘‘Information of the Interstate Transport ‘Good Neighbor’ Provision for the 2008 Ozone National Ambient Air Quality Standards (NAAQS) under Clean Air Act (CAA) Section 110(a)(2)(D)(i)(I),’’ January 22, 2015, available at: https://www3.epa.gov/airtransport/ GoodNeighborProvision2008NAAQS.pdf. VerDate Sep<11>2014 17:30 Oct 26, 2015 Jkt 238001 NAAQS. With respect to new or modified major stationary sources, the Prevention of Significant Deterioration (PSD) permitting program in the Washington SIP requires an owner or operator to demonstrate that the source will not contribute significantly to nonattainment or interfere with maintenance in another state. III. EPA Evaluation On August 4, 2015, the EPA issued a Notice of Data Availability (NODA) containing air quality modeling data that applies the CSAPR approach to contribution projections for the year 2017 for the 2008 8-hour ozone NAAQS.11 The moderate area attainment date for the 2008 ozone standard is July 11, 2018. In order to demonstrate attainment by this attainment deadline, states will use 2015 through 2017 ambient ozone data. Therefore, 2017 is an appropriate future year to model for the purpose of examining interstate transport for the 2008 ozone NAAQS. The EPA used photochemical air quality modeling to project ozone concentrations at air quality monitoring sites to 2017 and estimated state-by-state ozone contributions to those 2017 concentrations. This modeling used the Comprehensive Air Quality Model with Extensions (CAMx version 6.11) to model the 2011 base year, and the 2017 future base case emissions scenarios to identify projected nonattainment and maintenance sites with respect to the 2008 ozone NAAQS in 2017. The EPA used nationwide state-level ozone source apportionment modeling (CAMx Ozone Source Apportionment Technology/Anthropogenic Precursor Culpability Analysis technique) to quantify the contribution of 2017 base case NOX and VOC emissions from all sources in each state to the 2017 projected receptors. The air quality model runs were performed for a modeling domain that covers the 48 contiguous United States and adjacent portions of Canada and Mexico. The NODA and the supporting technical documents have been included in the docket for this action. The modeling data released in the NODA on July 23, 2015, is the most upto-date information the EPA has developed to inform our analysis of upwind state linkages to downwind air quality problems. For purposes of evaluating Washington’s interstate transport SIP submittal with respect to 11 See 80 FR 46271 (August 4, 2015) (Notice of Availability of the Environmental Protection Agency’s Updated Ozone Transport Modeling Data for the 2008 Ozone National Ambient Air Quality Standard (NAAQS)). PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 the 2008 8-hour ozone standard, the EPA is proposing that states whose contributions are less than one percent to downwind nonattainment and maintenance receptors are considered non-significant. The modeling indicates that Washington’s largest contribution to any projected downwind nonattainment site is 0.22 ppb and Washington’s largest contribution to any projected downwind maintenance-only site is 0.09 ppb.12 These values are below the one percent screening threshold of 0.75 ppb, and therefore there are no identified linkages between Washington and 2017 downwind projected nonattainment and maintenance sites. Note that the EPA has not done an assessment to determine the applicability for the use of the one percent screening threshold for western states that contribute above the one percent threshold. There may be additional considerations that may impact regulatory decisions regarding ‘‘potential’’ linkages in the west identified by the modeling. IV. Proposed Action As discussed in Section II, Washington concluded that emissions from the State do not significantly contribute to nonattainment or interfere with maintenance of the 2008 ozone standard in any other state. The EPA’s modeling, discussed in Section III, confirms this finding. Based on the modeling data and the information provided in Washington’s May 11, 2015 submittal, we are proposing to approve the submittal for purposes of meeting the CAA section 110(a)(2)(D)(i)(I) requirements for the 2008 ozone standard. The EPA’s modeling confirms the results of the State’s analysis: Washington does not significantly contribute to nonattainment or interfere with maintenance of the 2008 ozone standard in any other state. 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 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: 12 80 E:\FR\FM\27OCP1.SGM FR 46271 at page 46277, Table 3. 27OCP1 Federal Register / Vol. 80, No. 207 / Tuesday, October 27, 2015 / Proposed Rules srobinson on DSK5SPTVN1PROD with PROPOSALS • 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.

Approval and Promulgation of Implementation Plans; Washington: 
Interstate Transport of Ozone

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Clean Air Act (CAA) requires each State Implementation 
Plan (SIP) to contain adequate provisions prohibiting emissions that 
will have certain adverse air quality effects in other states. On May 
11, 2015, the State of Washington made a submittal to the Environmental 
Protection Agency (EPA) to address these requirements. The EPA is 
proposing to approve the submittal as meeting the requirement that each 
SIP contain adequate provisions to prohibit emissions that will 
contribute significantly to nonattainment or interfere with maintenance 
of the 2008 ozone National Ambient Air Quality Standard (NAAQS) in any 
other state.

I. Background

    On March 12, 2008, the EPA revised the levels of the primary and 
secondary 8-hour ozone standards from 0.08 parts per million (ppm) to 
0.075 ppm (73 FR 16436). The CAA requires states to submit, within 
three years after promulgation of a new or revised standard, SIPs 
meeting the applicable ``infrastructure'' elements of sections 
110(a)(1) and (2). One of these applicable infrastructure elements, CAA 
section 110(a)(2)(D)(i), requires SIPs to contain ``good neighbor'' 
provisions to prohibit certain adverse air quality effects on 
neighboring states due to interstate transport of pollution. There are 
four sub-elements within CAA section 110(a)(2)(D)(i). This action 
addresses the first two sub-elements of the good neighbor provisions, 
at CAA section 110(a)(2)(D)(i)(I). These sub-elements require that each 
SIP for a new or revised standard 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'' or ``interfere with maintenance'' of the applicable 
air quality standard in any other state. We note that the EPA has 
addressed the interstate transport requirements of CAA section 
110(a)(2)(D)(i)(I) for the eastern portion of the United States in 
several past regulatory actions.\1\ We most recently promulgated the 
Cross-State Air Pollution Rule (CSAPR), which addressed CAA section 
110(a)(2)(D)(i)(I) in the eastern portion of the United States.\2\ 
CSAPR addressed multiple national ambient air quality standards, but 
did not address the 2008 8-hour ozone standard.\3\

Clean Air Interstate Rule (CAIR), 70 FR 25172 (May 12, 2005); Cross-
State Air Pollution Rule (CSAPR), 76 FR 48208 (August 8, 2011).
    \2\ 76 FR 48208.
    \3\ CSAPR addressed the 1997 8-hour ozone, and the 1997 and 2006 
fine particulate matter NAAQS.
---------------------------------------------------------------------------

    In CSAPR, the EPA used detailed air quality analyses to determine 
whether an eastern state's contribution to downwind air quality 
problems was at or above specific thresholds. If a state's contribution 
did not exceed the specified air quality screening threshold, the state 
was not considered ``linked'' to identified downwind nonattainment and 
maintenance receptors and was therefore not considered to significantly 
contribute to or interfere with maintenance of the standard in those 
downwind areas. If a state exceeded that threshold, the state's 
emissions were further evaluated, taking into account both air quality 
and cost considerations, to determine what, if any, emissions 
reductions might be necessary. For the reasons stated below, we believe 
it is appropriate to use the same approach we used in CSAPR to 
establish an air quality screening threshold for the evaluation of 
interstate transport requirements for the 2008 ozone standard.
    In CSAPR, the EPA proposed an air quality screening threshold of 
one percent of the applicable NAAQS and requested comment on whether 
one percent was appropriate.\4\ The EPA evaluated the comments received 
and ultimately determined that one percent was an appropriately low 
threshold because there were important, even if relatively small, 
contributions to identified nonattainment and maintenance receptors 
from multiple upwind states. In response to commenters who advocated a 
higher or lower threshold than one percent, the EPA compiled the 
contribution modeling results for CSAPR to analyze the impact of 
different possible thresholds for the eastern United States. The EPA's 
analysis showed that the one-percent threshold captures a high 
percentage of the total pollution transport affecting downwind states, 
while the use of higher thresholds would exclude increasingly larger 
percentages of total transport. For example, at a five percent 
threshold, the majority of interstate pollution transport affecting 
downwind receptors would be excluded.\5\ In addition, the EPA 
determined that it was important to use a relatively lower one-percent 
threshold because there are adverse health impacts associated with 
ambient ozone even at low levels.\6\ The EPA also determined that a 
lower threshold such as 0.5 percent would result in modest increases in 
the overall percentages of fine particulate matter and ozone pollution 
transport captured relative to the amounts captured at the one-percent 
level. The EPA determined that a ``0.5 percent threshold could lead to 
emission reduction responsibilities in additional states that 
individually have a very small impact on those receptors--an indicator 
that emission controls in those states are likely to have a smaller air 
quality impact at the downwind receptor. We are not convinced that 
selecting a threshold below one percent is necessary or desirable.''

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

    In the final CSAPR, the EPA determined that one percent was a 
reasonable choice considering the combined downwind impact of multiple 
upwind states in the eastern United States, the health effects of low 
levels of fine particulate matter and ozone pollution, and the EPA's 
previous use of a one-percent threshold in CAIR. The EPA used a single 
``bright line'' air quality threshold equal to one percent of the 1997 
8-hour ozone standard, or 0.08 ppm.\8\ The projected contribution from 
each state was averaged over multiple days with projected high modeled 
ozone, and then compared to the one-percent threshold. We concluded 
that this approach for setting and applying the air quality threshold 
for ozone was appropriate because it provided a robust metric, was 
consistent with the approach for fine particulate matter used in CSAPR, 
and because it took into account, and would be applicable to, any 
future ozone standards below 0.08 ppm.\9\

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)(I) for 
the 2008 ozone NAAQS. The Washington submittal

[[Page 65674]]

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 submittal 
complies with the procedural requirements for SIP revisions under CAA 
section 110 and the EPA's implementing regulations.
    With respect to the requirements in CAA section 110(a)(2)(D)(i)(I), 
the Washington submittal referred to applicable rules in the Washington 
SIP, 2011 National Emissions Inventory (NEI) data, and modeling 
conducted by the State using the Motor Vehicle Emission Simulator 
(MOVES2014, database version 20141021). Washington noted that efforts 
by the EPA and states to address ozone transport have historically been 
focused on reductions of nitrogen oxides (NOX), a precursor 
to ozone formation, and provided 2011 NEI data for the major 
NOX emissions categories in the State. Washington found that 
on-road mobile sources comprise 57 percent of total NOX 
emissions, non-road mobile sources represent 11 percent, and the third 
largest group, point sources, comprises 9 percent of all Washington 
NOX emissions in 2011. Washington then performed MOVES2014 
modeling to look specifically at past and future trends in on-road and 
non-road mobile sources, the two largest source categories in 
Washington, for the years 2000 through 2020. The MOVES2014 modeling 
showed sustained, continuous reductions in NOX emissions 
from approximately 800 tons per day in 2000 to approximately 250 tons 
per day projected in 2020. Based on this evidence, and the EPA's draft 
photochemical air quality modeling data available at the time of 
Washington's submission, the State concluded that emissions of ozone 
precursors from Washington sources will not significantly contribute to 
nonattainment or interfere with maintenance of the 2008 ozone NAAQS in 
any other state.\10\
---------------------------------------------------------------------------

    \10\ See Memorandum from Stephen D. Page entitled ``Information 
of the Interstate Transport `Good Neighbor' Provision for the 2008 
Ozone National Ambient Air Quality Standards (NAAQS) under Clean Air 
Act (CAA) Section 110(a)(2)(D)(i)(I),'' January 22, 2015, available 
at: https://www3.epa.gov/airtransport/GoodNeighborProvision2008NAAQS.pdf.
---------------------------------------------------------------------------

    The Washington submittal provided further information to support 
this conclusion by citing the stationary source permitting regulations 
approved into the Washington SIP that require new sources and 
modifications to protect the ambient air quality standards, including 
the 2008 ozone NAAQS. With respect to new or modified major stationary 
sources, the Prevention of Significant Deterioration (PSD) permitting 
program in the Washington SIP requires an owner or operator to 
demonstrate that the source will not contribute significantly to 
nonattainment or interfere with maintenance in another state.

III. EPA Evaluation

    On August 4, 2015, the EPA issued a Notice of Data Availability 
(NODA) containing air quality modeling data that applies the CSAPR 
approach to contribution projections for the year 2017 for the 2008 8-
hour ozone NAAQS.\11\ The moderate area attainment date for the 2008 
ozone standard is July 11, 2018. In order to demonstrate attainment by 
this attainment deadline, states will use 2015 through 2017 ambient 
ozone data. Therefore, 2017 is an appropriate future year to model for 
the purpose of examining interstate transport for the 2008 ozone NAAQS. 
The EPA used photochemical air quality modeling to project ozone 
concentrations at air quality monitoring sites to 2017 and estimated 
state-by-state ozone contributions to those 2017 concentrations. This 
modeling used the Comprehensive Air Quality Model with Extensions (CAMx 
version 6.11) to model the 2011 base year, and the 2017 future base 
case emissions scenarios to identify projected nonattainment and 
maintenance sites with respect to the 2008 ozone NAAQS in 2017. The EPA 
used nationwide state-level ozone source apportionment modeling (CAMx 
Ozone Source Apportionment Technology/Anthropogenic Precursor 
Culpability Analysis technique) to quantify the contribution of 2017 
base case NOX and VOC emissions from all sources in each 
state to the 2017 projected receptors. The air quality model runs were 
performed for a modeling domain that covers the 48 contiguous United 
States and adjacent portions of Canada and Mexico. The NODA and the 
supporting technical documents have been included in the docket for 
this action.
---------------------------------------------------------------------------

    \11\ See 80 FR 46271 (August 4, 2015) (Notice of Availability of 
the Environmental Protection Agency's Updated Ozone Transport 
Modeling Data for the 2008 Ozone National Ambient Air Quality 
Standard (NAAQS)).
---------------------------------------------------------------------------

    The modeling data released in the NODA on July 23, 2015, is the 
most up-to-date information the EPA has developed to inform our 
analysis of upwind state linkages to downwind air quality problems. For 
purposes of evaluating Washington's interstate transport SIP submittal 
with respect to the 2008 8-hour ozone standard, the EPA is proposing 
that states whose contributions are less than one percent to downwind 
nonattainment and maintenance receptors are considered non-significant. 
The modeling indicates that Washington's largest contribution to any 
projected downwind nonattainment site is 0.22 ppb and Washington's 
largest contribution to any projected downwind maintenance-only site is 
0.09 ppb.\12\ These values are below the one percent screening 
threshold of 0.75 ppb, and therefore there are no identified linkages 
between Washington and 2017 downwind projected nonattainment and 
maintenance sites. Note that the EPA has not done an assessment to 
determine the applicability for the use of the one percent screening 
threshold for western states that contribute above the one percent 
threshold. There may be additional considerations that may impact 
regulatory decisions regarding ``potential'' linkages in the west 
identified by the modeling.

IV. Proposed Action

    As discussed in Section II, Washington concluded that emissions 
from the State do not significantly contribute to nonattainment or 
interfere with maintenance of the 2008 ozone standard in any other 
state. The EPA's modeling, discussed in Section III, confirms this 
finding. Based on the modeling data and the information provided in 
Washington's May 11, 2015 submittal, we are proposing to approve the 
submittal for purposes of meeting the CAA section 110(a)(2)(D)(i)(I) 
requirements for the 2008 ozone standard. The EPA's modeling confirms 
the results of the State's analysis: Washington does not significantly 
contribute to nonattainment or interfere with maintenance of the 2008 
ozone standard in any other state.

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 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:

[[Page 65675]]

     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 
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 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).
    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 as specified 
by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it 
impose substantial direct costs on tribal governments or preempt tribal 
law.
