Approval and Promulgation of Implementation Plans; New Mexico; 
Interstate Transport of Pollution

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is approving a State Implementation Plan (SIP) revision 
submitted by the State of New Mexico for the purpose of addressing the 
``good neighbor'' provisions of the Clean Air Act (CAA) section 
110(a)(2)(D)(i) for the 1997 ozone standards and the 1997 
PM2.5 standards. This SIP revision satisfies a portion of 
the State of New Mexico's obligation to submit a SIP revision that 
demonstrates that adequate provisions are in place to prohibit air 
emissions from adversely affecting another state's air quality through 
interstate transport. This rulemaking action is being taken under 
section 110 of the CAA and addresses one element of CAA section 
110(a)(2)(D)(i), which pertains to prohibiting air pollutant emissions 
from within New Mexico from significantly contributing to nonattainment 
of the ozone and PM2.5 NAAQS in any state.

DATES: This direct final rule will be effective June 7, 2010 without 
further notice unless EPA receives relevant adverse comments by May 10, 
2010. If adverse comments are received, EPA will publish a timely 
withdrawal of the direct final rule in the Federal Register informing 
the public that the rule will not take effect.

VI. Statutory and Executive Order Reviews

I. What Action Is EPA Taking?

    We are approving a submission from the State of New Mexico 
demonstrating that New Mexico has adequately addressed one of the 
required elements of the CAA section 110(a)(2)(D)(i), the element that 
prohibits air pollutant emissions from sources within a state from 
significantly contributing to nonattainment of the relevant NAAQS in 
any other state. We have determined that emissions from sources in New 
Mexico do not significantly contribute to nonattainment of the 1997 
ozone standards or of the 1997 PM2.5 standards in any other 
state. The remaining three

[[Page 17869]]

elements of section 110(a)(2)(D) are SIPs addressing: (i) Interference 
with the maintenance of the NAAQS in any other state; (ii) interference 
with measures required to prevent significant deterioration of air 
quality in any other state; and (iii) interference with measures 
required to protect visibility in any other state. The aforementioned 3 
elements will be evaluated and addressed in future rulemakings.
    EPA is publishing this rule without prior proposal because we view 
this as a noncontroversial amendment and anticipate no adverse 
comments. However, in the proposed rules section of this Federal 
Register publication, we are publishing a separate document that will 
serve as the proposal to approve the SIP revision if adverse comments 
are received. This rule will be effective on June 7, 2010 without 
further notice unless we receive adverse comment by May 10, 2010. If we 
receive adverse comments, we will publish a timely withdrawal in the 
Federal Register informing the public that the rule will not take 
effect. We will address all public comments in a subsequent final rule 
based on the proposed rule. We will not institute a second comment 
period on this action. Any parties interested in commenting must do so 
at this time. Please note that if we receive adverse comment on an 
amendment, paragraph, or section of this rule and if that provision may 
be severed from the remainder of the rule, we may adopt as final those 
provisions of the rule that are not the subject of an adverse comment.

II. What Is a SIP?

    Section 110(a) of the CAA requires each state to develop a plan 
that provides for the implementation, maintenance, and enforcement of 
the national ambient air quality standards (NAAQS). EPA establishes 
NAAQS under section 109 of the CAA. Currently, the NAAQS address six 
criteria pollutants: Carbon monoxide, nitrogen dioxide, ozone, lead, 
particulate matter, and sulfur dioxide.
    The plan developed by a state is referred to as the state 
implementation plan (SIP). The content of the SIP is specified in 
section 110 of the CAA, other provisions of the CAA, and applicable 
regulations. SIPs can be extensive, containing state regulations or 
other enforceable measures and various types of supporting information, 
such as emissions inventories, monitoring networks, and modeling 
demonstrations.
    A primary purpose of the SIP is to provide the air pollution 
regulations, control strategies, and other means or techniques 
developed by the state to ensure that the ambient air within that state 
meets the NAAQS. However, another important aspect of the SIP is to 
ensure that emissions from within the state do not have certain 
prohibited impacts upon the ambient air in other states through 
interstate transport of pollutants. This SIP requirement is specified 
in section 110(a)(2)(D). Pursuant to that provision, each state's SIP 
must contain provisions adequate to prevent, among other things, 
emissions that significantly contribute to violations of the NAAQS in 
any other state.
    States are required to update or revise SIPs under certain 
circumstances. One such circumstance is EPA's promulgation of a new or 
revised NAAQS. Each state must submit these revisions to EPA for 
approval and incorporation into the federally-enforceable SIP.

III. What Is the Background for This Action?

    On July 18, 1997, EPA promulgated new standards for 8-hour ozone 
and fine particulate matter (PM2.5). This action is being 
taken in response to the July 18, 1997 revision to the 8-hour ozone 
standards and PM2.5 standards. This action does not address 
the requirements for the 2006 PM2.5 standards or the 2008 8-
hour ozone standards; those standards will be addressed in a later 
action.
    Section 110(a)(1) of the CAA requires states to submit SIPs to 
address a new or revised NAAQS within 3 years after promulgation of 
such standards, or within such shorter period as EPA may prescribe. 
Section 110(a)(2) lists the elements that such new SIPs must address, 
as applicable, including section 110(a)(2)(D)(i) which pertains to 
interstate transport of certain emissions. On August 15, 2006, EPA 
issued its ``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'' (``Guidance'') for SIP submissions that states should use 
to address the requirements of section 110(a)(2)(D)(i). EPA developed 
this guidance to make recommendations to states for making submissions 
to meet the requirements of section 110(a)(2)(D) for the 1997 8-hour 
ozone standards and 1997 PM2.5 standards.
    On September 17, 2007, we received a SIP revision from the State of 
New Mexico to address the requirements of section 110(a)(2)(D)(i) for 
both the 1997 8-hour ozone standards and 1997 PM2.5 
standards. This SIP submittal follows EPA's Guidance. As identified in 
the Guidance, the ``good neighbor'' provisions in section 
110(a)(2)(D)(i) require each State to submit a SIP that prohibits 
emissions that adversely affect another state in the ways contemplated 
in the statute. Section 110(a)(2)(D)(i) contains four distinct 
requirements related to the impacts of interstate transport; however, 
in this rulemaking EPA is addressing only the requirement that pertains 
to preventing sources in the state from emitting pollutants in amounts 
which will contribute significantly to nonattainment of the 1997 8-hour 
ozone standards and 1997 PM2.5 standards in any other state. 
In its submission, the State of New Mexico indicated that its current 
SIP is adequate to prevent such significant contribution to 
nonattainment in any other state, and thus no additional emissions 
controls are necessary at this time to alleviate interstate transport.

IV. What Is EPA's Evaluation of the State's Submission?

    In accordance with EPA's Guidance, the State of New Mexico has made 
a SIP submission addressing interstate transport for the 1997 8-hour 
ozone standards and 1997 PM2.5 standards. The State has made 
a showing that emissions from New Mexico do not significantly 
contribute to violations of either NAAQS in other states by two 
different means. For PM2.5 the State has relied primarily 
upon technical analysis performed by EPA in connection with another 
regional rulemaking that addresses interstate transport. For ozone, the 
State has relied primarily on additional modeling to address the extent 
of interstate transport. We believe that the submission adequately 
establishes that emissions from New Mexico do not significantly 
contribute to violations of either NAAQS in other states, for the 
reasons explained below.
    To support a determination of no ``significant contribution'' for 
the 1997 PM2.5 standards, the state has relied on EPA's 
Clean Air Interstate Rule (CAIR) \1\ analysis. This approach is 
consistent with EPA's Guidance to states for this SIP submission. In 
CAIR, EPA evaluated which states significantly contribute to violations 
of the 1997 8-hour ozone standards and 1997 PM2.5 standards 
in other states. Based upon its analysis, EPA did not include New 
Mexico in the CAIR region. In the CAIR preamble, EPA provided its 
rationale for the exclusion

[[Page 17870]]

of the western states, including New Mexico, from further consideration 
of transport for 8-hour ozone and PM2.5 and the requirements 
of CAIR.

Particulate Matter and Ozone (Clean Air Interstate Rule); Revisions 
to Acid Rain Program; Revisions to the NOX SIP Call; 
Final Rule,'' 70 FR 25162 (May 12, 2005). Information regarding CAA 
section 110(a)(2)(D) SIPs can be found beginning of page 25263.
---------------------------------------------------------------------------

    The ``Technical Support Document for the Interstate Air Quality 
Rule Air Quality Modeling Analysis'', January 2004 (available at http://www.epa.gov/cair/technical.html) contains documentation of the 
modeling used to support CAIR. This modeling included an analysis of 
the maximum impact of emissions from States without CAIR controls 
applied on areas projected in PM2.5 nonattainment in 2010. A 
maximum impact level of 0.15 [micro]g/m\3\ was considered significant 
for this analysis (Note: In the final CAIR EPA changed the maximum 
impact level for this significance test to 0.20 [micro]g/m\3\). EPA's 
modeling indicated that the maximum impact from emissions from sources 
in New Mexico on any projected nonattainment area in another state was 
0.03 [micro]g/m\3\. This value is 20% of the significant impact level 
that EPA used in the CAIR proposal, and therefore EPA determined that 
emissions from the state of New Mexico do not significantly contribute 
to pollutant levels in any area projected to be nonattainment of the 
PM2.5 standard in that analysis.
    CAIR was remanded by the U.S. Court of Appeals for the District of 
Columbia, and EPA is currently in the process of developing a 
replacement rule to address interstate transport for the 1997 8-hour 
ozone and 1997 PM2.5 standards. We do not believe that the 
CAIR remand affects New Mexico's reliance on EPA's CAIR analysis for 
the purpose of evaluating New Mexico's PM 2.5 impacts on 
other states. Specifically, EPA's modeling was conducted without 
including the impact of any CAIR controls, and thus the evaluation is 
not impacted by any uncertainty in the implementation of CAIR controls 
due to the remand. Also, despite remand of the CAIR rules, EPA's 
reliance on the maximum impact level of 0.20 [micro]g/m\3\ as the 
cutoff for the inclusion of a state in the CAIR region was upheld by 
the court. Therefore, with respect to the 1997 PM2.5 
standards, we believe that New Mexico's submission adequately 
establishes that sources in that state are not significantly 
contributing to violations of that NAAQS in any other state.
    To support a determination of no ``significant contribution'' for 
the 8-hour ozone NAAQS, New Mexico could not rely upon EPA's CAIR 
analysis because western states including New Mexico were not included 
in the area modeled for ozone. Instead, New Mexico provided an 
additional modeling analysis of the impact of emissions from the state 
on projected 8-hour ozone nonattainment in downwind states. We note 
that modeling is not necessarily required to support this type of SIP 
submission, but this approach is consistent with EPA's Guidance to 
states for this SIP submission.
    The modeling relied upon by the state is described in greater 
detail in its technical support document in the submission, and is 
available at http://www.regulations.gov, Docket No. EPA-R06-OAR-2007-
0993. We note that EPA assisted the state with this analysis, including 
the development of the modeling demonstration. In order to develop a 
model scenario that could evaluate New Mexico's impacts, the state and 
EPA determined that it was appropriate to rely on data developed by the 
Central Regional Air Planning Association (CENRAP). Modeling was 
conducted using a 2002 third quarter CENRAP modeling dataset that 
included New Mexico in the modeling domain. While a more recent dataset 
might be assumed to be more appropriate to support this action, a 2010 
dataset was not available from CENRAP. However, we believe that the use 
of the 2002 dataset is adequate to evaluate the degree of contribution 
of New Mexico emissions sources to violations of the 1997 8-hour ozone 
standards. Because the analysis is based on year 2002 emissions, we 
believe it is a conservative estimate of potential transport impacts in 
2010, as New Mexico's emissions have been decreasing since 2002 due to 
various recent federal control programs (including On-Road and Nonroad 
reductions). This trend is confirmed by available 2005 inventory. In 
other words, if data from 2002 establish that there is no significant 
contribution to violations of the 1997 8-hour ozone standards in other 
states, then New Mexico sources would have even lower impacts currently 
and consequently no significant contribution.
    In the Guidance, we recommended a number of ways that states might 
elect to evaluate whether or not there is significant contribution, and 
we suggested that states might consider assessing the potential for 
contribution using assumptions similar to those used by EPA in CAIR. 
The state's analysis considered three factors comparable to those used 
by EPA as screening criteria in determining significance for states in 
CAIR: (a) The magnitude of the contribution, (b) the frequency of the 
contribution, and (c) the relative amount of contribution. The 
additional modeling yielded consistent results showing New Mexico 
emissions do not contribute significantly to 8-hour ozone nonattainment 
in any of the areas analyzed. New Mexico's highest overall contribution 
to total nonattainment for any nonattainment area at the time of the 
modeling was for Dallas/Fort Worth. New Mexico's highest impact on the 
Dallas/Fort Worth area was a daily average contribution of 0.4%, with a 
contribution average of 0.4 ppb. By EPA's own metrics (as established 
in CAIR and upheld by the court), these impacts are considered to be 
small and infrequent and well below screening criteria established at 
1% and 2 ppb, respectively. Moreover, not a single metric of the three 
contribution factors was found to be above the significance threshold 
established by EPA for any of the downwind counties. For more details 
please see the document titled ``Modeling Data and Report for New 
Mexico from EPA Regions 6 and 7'' that is included in the docket 
materials for this action.
    At the time the modeling was performed, Denver's air quality was 
meeting the standard. (The 2004-2006 8-Hour Ozone Design Value (DV) was 
81 ppb). Therefore the state did not evaluate New Mexico's ozone 
impacts on Denver. Denver had a very high ozone season in 2007 that 
temporarily pushed the area into nonattainment. The preliminary 2007-
2009 DV (awaiting final data validation) is 82 ppb so the area appears 
to now be back in attainment. The preliminary 2007-2009 DV is based 
upon 4th High values of 90 ppb in 2007, 79 ppb in 2008, and 79 ppb in 
2009 (preliminary). With the last two 4th Highs of 79 ppb, Denver would 
have to monitor a 4th High value of 97 ppb in 2010 to go back into 
nonattainment for the period 2008-2010. Denver has not had a 4th High 
value of more than 92 ppb in the last 15 years, so it is unlikely that 
Denver will be in nonattainment at the end of the 2010 ozone season for 
the 84 ppb standard. Since based on preliminary 2007-2009 data, Denver 
is attaining the standard, New Mexico's emissions should not be 
considered as contributing to nonattainment in Denver.
    With respect to the 1997 8-hour ozone standards, we believe that 
New Mexico's submission adequately establishes that sources in that 
state are not significantly contributing to violations of that NAAQS in 
any other state. As noted previously, EPA will be acting on the other 
elements of Section 110(a)(2)(D)(i) in separate rulemakings.

V. Final Action

    We are approving revisions to the New Mexico SIP which adequately 
demonstrates that air pollutant emissions from sources within New

[[Page 17871]]

Mexico do not add significantly to nonattainment of the relevant NAAQAS 
on any other state.
    Based on the information provided by NMED in the technical 
demonstration, it has sufficiently been demonstrated that emissions 
from New Mexico do not significantly contribute to downwind 
nonattainment. Thus, EPA concludes that the New Mexico SIP complies 
with CAA section 110(a)(2)(D)(i)(I).

VI. 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, EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
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 Clean Air Act; and
     Does not provide 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, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the state, and EPA notes that it will not 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. 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 June 7, 2010. 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).)
