[EPA-R10-OAR-2013-0247; FRL-9917-38-Region 10]

Revision to the Idaho State Implementation Plan; Approval and 
Promulgation of Air Quality Implementation Plans: Idaho, Northern Ada 
County PM10 Second Ten-Year Maintenance Plan and Pinehurst 
PM10 Contingency Measures

AGENCY: Environmental Protection Agency.

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving the 
Northern Ada County PM10 Second Ten-Year Maintenance Plan 
submitted by the Idaho Department of Environmental Quality (IDEQ) on 
March 11, 2013, for particulate matter with an aerodynamic diameter 
less than or equal to ten micrometers (PM10). Northern Ada 
County was identified as an area of concern for PM10 with 
the promulgation of the PM10 NAAQS in 1987, and was formally 
designated as a moderate PM10 nonattainment area upon 
passage of the 1990 Clean Air Act (CAA) amendments. In October 2003, 
the EPA approved the Northern Ada County PM10 Maintenance 
Plan and redesignated the area to attainment for PM10. This 
revised Maintenance Plan addresses maintenance of the PM10 
standard for a second ten-year period beyond redesignation through 
2023, extends the horizon years, and contains revised transportation 
conformity budgets. The EPA is also approving the February 15-16, 2011 
high wind exceptional event at the Boise Fire Station monitor, as well 
as contingency measures for the Pinehurst PM10 Air Quality 
Improvement Plan. The EPA is approving the second ten-year 
PM10 Maintenance Plan for Northern Ada County and the 
Pinehurst PM10 contingency measures pursuant to section 110 
of the CAA. The EPA is approving the February 2011 exceptional event 
pursuant to 40 CFR 50.14. The EPA received one set of adverse comments 
focused primarily on proposed coal export terminals that may be built 
in Oregon and Washington that may affect Northern Ada County.

DATES: This final rule is effective on November 3, 2014.

I. Background

    Northern Ada County was identified as an area of concern for 
PM10 with the promulgation of the PM10 NAAQS in 
1987, and was formally designated as a moderate PM10 
nonattainment area upon passage of the 1990 CAA amendments. Idaho 
developed a state implementation plan (SIP) and submitted it to the EPA 
in November 1991, later submitting revisions in December 1994 and July 
1995. The EPA approved the Northern Ada County PM10 SIP on 
May 30, 1996 (61 FR 27019). Idaho submitted a maintenance plan and a 
request to redesignate the area to attainment on September 27, 2002, 
and provided supplemental information on July 10 and 21, 2003. On 
October 27, 2003, the EPA approved the Northern Ada County 
PM10 Maintenance Plan and redesignated the area to 
attainment status for PM10 (68 FR 61106).
    In actions dated August 25, 1994 (59 FR 43475) and May 26, 1995 (60 
FR 27891), the EPA conditionally approved the SIP for the Pinehurst, 
Idaho PM10 nonattainment area. The conditional approval 
concluded that IDEQ had not satisfied the requirement for contingency 
measures for both the City

[[Page 59436]]

of Pinehurst and the Pinehurst Expansion area. The EPA set a deadline 
of July 20, 1995 for IDEQ to submit the required contingency measures. 
IDEQ met the established deadline with its submission ``Contingency 
Measures for the Pinehurst PM10 Air Quality Improvement 
Plan,'' dated July 13, 1995.
    On September 23, 2013, IDEQ submitted documentation in accordance 
with the Exceptional Events Rule (40 CFR 50.14) to demonstrate that the 
monitored PM10 values on February 15-16, 2011 at the Boise 
monitor were due to a high wind event and resulting dust storm that 
originated in Nevada. The EPA proposed approval of this maintenance 
plan and the Pinehurst Contingency Measures on February 20, 2014 (79 FR 
9697).

II. Response to Comments

    On March 24, 2014, the EPA received one set of comments opposing 
the EPA's proposed approval of Northern Ada County PM10 
Second Ten-Year Maintenance Plan (Ada County PM10 plan). The 
comments were focused on the potential impact that possible coal export 
terminals, proposed to be built in the Pacific Northwest, could have on 
PM10 concentrations in the maintenance area. These comments 
are similar to comments previously submitted on February 22, 2013, 
related to emissions impacts of locomotive coal transport in the 
emissions inventory for the Tacoma fine particulate (PM2.5) 
nonattainment area (78 FR 32131, May 29, 2013) and comments submitted 
on March 10, 2014, related to the Kent, Seattle, and Tacoma Second 10-
Year PM10 Limited Maintenance Plan (79 FR 49239, August 20, 
2014). The EPA responded to these comments in the May 29, 2013 and 
August 20, 2014 final rulemakings. Due to the specific focus of today's 
action, the EPA is only addressing those comments directly relevant to 
the Ada County PM10 plan.

A. Calculating Growth in Locomotive Traffic

    Comment: The commenter requested that the EPA disapprove the Ada 
County PM10 plan because the plan relied on general growth 
factors in estimating future railroad traffic without consideration of 
future growth associated with proposed coal export terminals that may 
be built in Oregon and Washington.
    Response: The EPA guidance regarding development of emissions 
inventories requires states to consider reasonably anticipated growth 
in emission sources such as increased vehicle miles traveled, 
population growth, and possible emissions growth at permitted 
stationary sources.\1\ None of the projects in question are far enough 
along in their development that the scope or impact of their emissions 
can be estimated with any degree of certainty. In this case, the 
Washington State Environmental Policy Act (SEPA) and/or the National 
Environmental Policy Act (NEPA) processes for coal export proposals 
cited in the March 24, 2014 letter are ongoing. It is not known whether 
the facilities will be constructed, and if they are constructed, the 
size and scope of operations that would be authorized. In addition, as 
the commenter notes, there are several possible rail routes that could 
be used in the future and it is not known whether locomotive traffic 
associated with coal shipments would traverse or bypass the Ada County 
maintenance area or, as may be the case, whether routes would 
constantly vary based on decisions by the rail operator. Given the 
range of uncertainty surrounding the proposed terminals, including 
whether the terminals will be constructed, the location (s) of such 
terminals and decisions of terminal and railway operators that would 
affect rail routes, the EPA believes it would be unreasonable to 
disapprove the Ada County PM10 plan on the basis that the 
emissions inventory did not estimate potential future events that may 
or may not impact the maintenance area. Should any of these coal export 
facilities be built in the future, both the EPA and the State have the 
authority under the EPA's longstanding guidance regarding contingency 
measures to reexamine emissions inventories and establish additional 
control measures if a noticeable impact on PM10 levels in 
Ada County were to occur.\2\

B. Calculating Fugitive Dust Impacts From Coal Export Locomotive 
Traffic

    Comment: The commenter noted Washington State's Kent, Seattle, and 
Tacoma Second 10-Year PM10 Limited Maintenance Plan 
submittal which included a calculation of estimated fugitive coal dust 
emissions as part of the 2011 baseline emissions inventory for that 
area (Docket No. EPA-R10-OAR-2013-0713)(Kent, Seattle, and Tacoma 
PM10 plan). The commenter requested that the EPA disapprove 
the Ada County PM10 plan because it did not contain a 
comparable estimate of fugitive coal dust emissions.
    Response: A key difference between the Washington and Idaho plans 
is that there is already coal-related locomotive activity through the 
Washington maintenance areas on the way to export through Canada, 
captured as part of the 2011 baseline emissions inventory. The 
commenter provides no compelling evidence to suggest that Ada County 
experiences similar Canadian export traffic like Kent, Seattle, and 
Tacoma. Instead the commenter's focus is on proposed export terminals 
that may or may not be built in Oregon and Washington. As noted above, 
consideration of potential, future impacts of projects that may or may 
not be built is not a reasonable basis for disapproving the Ada County 
PM10 plan. The EPA also notes that the commenter raised 
several issues specific to the Kent, Seattle, and Tacoma 
PM10 plan fugitive dust estimation methodology which are not 
germane to the Ada County PM10 plan and therefore not 
addressed here.
    Comment: The Commenter noted that modeling conducted by the Sierra 
Club of the potential impacts of the proposed Ambre Energy Coyote 
Island Terminal in Morrow predicts elevated PM2.5 emissions. 
The commenter indicates that results for PM2.5 could be 
assumed to be PM10 and that this information is enough to 
conclude that there would be high levels of PM10 emissions 
that could result in exceedances in Ada County.
    Response: The Tran Modeling analysis evaluated potential emissions 
from the proposed Ambre Energy Coyote Island Terminal in Morrow, Oregon 
and calculated emissions near the facility at values above the NAAQS. 
Given the uncertainty surrounding the proposed Morrow Terminal, 
including whether the facility will be constructed, the EPA believes it 
would be unreasonable to disapprove the Ada County PM10 
Maintenance Plan on the basis of this modeling analysis. In addition, 
because the modeling predicts emission levels near the facility in 
Oregon, the EPA believes it is unreasonable to draw conclusions about 
how these emissions could affect Ada County, Idaho. Should this 
facility be built in the future, both the EPA and the state have the 
authority under the EPA's longstanding guidance regarding contingency 
measures to establish additional control measures if a noticeable 
impact on PM10 levels in Ada County were to occur.

III. Final Action

    The EPA is taking final action to approve the Northern Ada County 
PM10 Second Ten-Year Maintenance Plan and Pinehurst 
PM10 Contingency Measures. This action approves and 
incorporates into the SIP the PM10 control measures 
submitted by IDEQ on March 11, 2013 and July 13, 1995, respectively. 
The EPA is also approving the February 15-16, 2011 high wind 
exceptional event at the Boise Fire Station monitor. Provisions 
describing state or local enforcement authority are not incorporated 
into the SIP to avoid potential conflict with the EPA's independent 
authorities.

IV. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the 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 CAA. Accordingly, this 
action merely approves state law as meeting Federal requirements and 
does not impose additional requirements beyond those imposed by state 
law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501, et seq.);
     is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601, et seq.);
     does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     is not subject to 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 CAA; 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 or 
in any other area where 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.
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. The EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by December 1, 2014. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action for the purposes of 
judicial review nor does it extend the time within which a petition for 
judicial review may be filed, and shall not postpone the effectiveness 
of such rule or action. This action may not be challenged later in 
proceedings to enforce its requirements. (See section 307(b)(2)).
