[EPA-R06-OAR-2014-0237; FRL-9962-75-Region 6]


Approval and Promulgation of Implementation Plans; New Mexico; 
Regional Haze Progress Report State Implementation Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: Pursuant to the Federal Clean Air Act (CAA or the Act), the 
Environmental Protection Agency (EPA) is approving a revision to a 
State Implementation Plan (SIP) submitted by the State of New Mexico on 
March 14, 2014. New Mexico's SIP revision addresses requirements of the 
Act and the EPA's rules that require New Mexico to submit a periodic 
report assessing progress toward the reasonable progress goals (RPGs) 
for mandatory Class I Federal areas in and outside New Mexico with a 
determination of the adequacy of the State's existing regional haze 
SIP.

DATES: This rule is effective on July 14, 2017.

ADDRESSES: The EPA has established a docket for this action under

I. Background

    The background for this action is discussed in detail in the EPA's 
November 3, 2015 proposal.\1\ In that document, the EPA proposed to 
approve New Mexico's regional haze progress report SIP revision 
(submitted on March 14, 2014) as meeting the applicable regional haze 
requirements set forth in 40 CFR 51.309(d)(10). In addition, the EPA 
proposed to approve New Mexico's determination that the current 
regional haze SIP is adequate to meet the State's RPGs for the first 
planning period and requires no further substantive revision to achieve 
established goals for visibility improvement and emission reductions.
---------------------------------------------------------------------------

    \1\ See 80 FR 67682.
---------------------------------------------------------------------------

    The proposal and the accompanying technical support document (TSD) 
provide detailed descriptions of New Mexico's SIP revision and the 
rationale for the EPA's proposed approval of the State's submittal. 
Please see the docket for these and other documents regarding the 
proposal.
    The public comment period for the proposal closed on December 3, 
2015. The EPA received one set of comments in a letter dated December 
3, 2015, from the National Parks Conservation Association and the San 
Juan Citizens Alliance regarding the EPA's proposal. The comment letter 
is included in the publicly posted docket associated with this action 
at http://www.regulations.gov. Below, the EPA provides a summary of the 
comments received and corresponding responses. After careful 
consideration of the comments and the information provided, the EPA is 
approving the progress report, as proposed.

II. Response to Comments

    Comment: The commenter noted that New Mexico's progress report 
indicated that the State is no longer implementing its State Mobile 
Source Regulation but is relying on federal programs that will achieve 
the same reductions. The commenter argued that the progress report does 
not meet 40 CFR 51.309(d)(10)(i)(A) because it was not clear about the 
start date of the State's

[[Page 27128]]

reliance on federal programs for mobile source reduction or the impact 
that a delayed start had on visibility.
    Response: The comment does not demonstrate a failure to meet Sec.  
51.309(d)(10)(i)(A). This element requires a description of the status 
of implementation of all control measures included in the regional haze 
SIP for achieving RPGs for Class I areas both within and outside the 
State. As discussed in the proposal, New Mexico stated in the progress 
report that it is implementing all long-term control strategies with 
the exception of the formerly adopted, and now repealed, State Mobile 
Source Regulation. The State Mobile Source Regulation, when adopted in 
2007, would have applied the California motor vehicle standards within 
New Mexico. We do not agree that the provided details for Sec.  
51.309(d)(10)(i)(A) are lacking or inadequate. Section 
51.309(d)(10)(i)(A) requires only a description of the status of the 
implementation of the measures in the regional haze SIP, not an 
assessment of the effect of the implementation or failure to implement 
each specific measure. New Mexico's reliance on the federal program is 
unlikely to have a significant impact on visibility. At the time the 
regulation was adopted by New Mexico, the California standards were 
projected to substantially differ from federal motor vehicle emissions 
standards. Since that time, as the progress report notes, the 
California and federal programs for emissions standards for motor 
vehicles are more aligned with each other than was expected by New 
Mexico when it adopted the State Mobile Source Regulation.\2\
---------------------------------------------------------------------------

    \2\ For example, in 2009, the EPA and the National Highway 
Traffic Safety Administration (NHTSA) proposed ``regulatory 
convergence'' with California on motor vehicle fuel economy 
standards. See 74 FR 49454 (September 28, 2009). This was 
subsequently adopted, starting with model years 2012-2016. 75 FR 
25323 (May 7, 2010).
---------------------------------------------------------------------------

    Comment: The progress report does not meet 40 CFR 
51.309(d)(10)(i)(A) because it was not clear whether certain Western 
Regional Air Partnership (WRAP) policies, including the WRAP Policy on 
Enhanced Smoke Management Programs for Visibility and the WRAP Policy 
on Annual Emissions Goals for Fire, were incorporated into the State's 
Smoke Management Plan (SMP) and are being implemented.
    Response: Consistent with the recommendation of the Grand Canyon 
Visibility Transport Commission, the regional haze program under 40 CFR 
part 309 brings special attentiveness to smoke management. New Mexico 
adopted a revision to the New Mexico Administrative Code (NMAC) 
addressing smoke management to meet these regional haze rule 
requirements. The EPA previously approved New Mexico's regional haze 
SIP in 2012 as meeting the requirements of 40 CFR 51.309(d)(6), which 
deals with implementation plan requirements related to fire.\3\ In 
doing so, the EPA noted that the SMP operating within New Mexico was 
consistent with the WRAP Policy on Enhanced Smoke Management Programs 
for Visibility and the Wrap Policy on Annual Emissions Goals for Fire, 
both of which were appendices to the approved Regional Haze SIP.\4\ The 
progress report stated that New Mexico, aside from its update regarding 
State Mobile Source Regulation, is implementing the long-term 
strategies adopted into the regional haze SIP. This sufficiently 
indicates the status of implementation for the State's SMP. Therefore, 
we disagree that the progress report's discussion of the State's SMP 
failed to meet the requirements of 40 CFR 51.309(d)(1)(i)(A).
---------------------------------------------------------------------------

    \3\ See 77 FR 70693 (November 27,2012) (approving 20.2.65 NMAC 
(Smoke Management)).
    \4\ See 77 FR 36065.
---------------------------------------------------------------------------

    Comment: The progress report does not meet 40 CFR 
51.309(d)(10)(i)(B) because it did not include any information about 
emission reductions provided by the State's SMP. Annual emissions 
related to fire and estimated benefits should be readily available.
    Response: We do not agree with the assertion that the progress 
report fails to meet the requirements of 40 CFR 51.309(d)(10)(i)(B). 
While this provision requires a summary of the emission reductions 
achieved in the State through the implementation of the measures in its 
regional haze SIP, nothing in this provision requires the State to 
include estimates in its progress report of the emission reductions 
achieved by specific measures. Namely, there is no requirement for a 
detailed, causal analysis that pinpoints or links certain emission 
reductions to actual regional haze SIP measures. It is acceptable for 
the State to provide a summary of overall emission changes, rather than 
an analysis that attributes particular emission reductions from 
specific sources to certain measures in the plan, mainly when such a 
higher level summary does not indicate any problem with the direction 
and magnitude of these overall changes. We address in the response to a 
later comment the adequacy of the State's summary of overall emissions.
    Additionally, the comment misperceives the basis for inclusion of 
the SMP in the SIP. The visibility goal announced in section 169A of 
the CAA is both to prevent future impairment as well as remedy existing 
impairment. Regional haze SIPs accordingly may include programs to 
avert increases in emissions. The SMP is generally designed to limit 
increases in emissions, rather than to reduce existing emissions. As 
such, there would be little purpose for the State to try to estimate 
the specific emission reductions achieved through implementation of the 
program.\5\
---------------------------------------------------------------------------

    \5\ Consistent with these points, as reported on New Mexico's 
Smoke Management Program Web site, a fire emissions summary for 
2005-2016 shows no appreciable increases in SMP-regulated emissions. 
See New Mexico 2017 Annual Smoke Management Meeting Presentation, 
available at https://www.env.nm.gov/wp-content/uploads/2017/01/2016_Fire_Emissions.pdf.
---------------------------------------------------------------------------

    Comment: The progress report does not meet 40 CFR 
51.309(d)(10)(i)(B) because there were no estimates of reductions by 
the new source review (NSR) and prevention of significant deterioration 
(PSD) programs. The progress report did not indicate what emissions 
were avoided or allowed by the implementation of these programs.
    Response: As explained above, nothing in 40 CFR 51.309(d)(10)(i)(B) 
requires the State to include estimates in its progress report of the 
emission reductions achieved by specific measures included in the 
regional haze SIP.
    Additionally, although the regional haze SIP also cited the PSD and 
NSR programs, the primary benefit from these programs is to limit 
emission increases rather than precisely working to achieve reductions 
in existing emissions. Given this, there would be little purpose for 
New Mexico to try to estimate the specific emission reductions achieved 
through the implementation of these programs.
    Comment: The progress report does not meet 40 CFR 
51.309(d)(10)(i)(B) because point source data for sources reporting to 
the Clean Air Markets Database should be included.
    Response: This comment does not identify a basis to disapprove the 
SIP revision. Source-specific information on all electric generating 
units (the sources reporting to the Clean Air Markets Database) is not 
required in summarizing the emission reductions in the progress report. 
The submitted progress report provided detailed information on 
anticipated emission reductions at the San Juan Generating Station 
(SJGS). This facility is the largest point source in the State and the 
most significant New Mexico emission source in the Clean Air Markets 
Database. More

[[Page 27129]]

importantly, it is the only electric generating unit with definite 
emission limits in the New Mexico regional haze SIP. The progress 
report provided statewide point source emission data from 2008-2012 and 
compared it to the 2018 projected emission levels.\6\ While additional 
information from the Clean Air Markets Database regarding emissions 
from other electric generating units may be useful, it is not essential 
for the approval of the submitted progress report. As noted in the 
proposal, we compared the point source data in the progress report to 
that reported by the Clean Air Markets Database and found that the 
reported emissions were consistent with that data.
---------------------------------------------------------------------------

    \6\ See Figure 3.6 of Progress Report for the State 
Implementation Plan for Regional Haze, March 11, 2014.
---------------------------------------------------------------------------

    Comment: The progress report does not meet 40 CFR 
51.309(d)(10)(i)(B) because the inventories did not address all haze-
related pollutants. Emission inventories specific to particulate 
organic matter, coarse mass, ammonia (NH3), and volatile 
organic compounds (VOCs) should be included.
    Response: 40 CFR 51.309(d)(10)(i)(B) requires a summary of the 
emission reductions achieved throughout the State through 
implementation of the control measures mentioned in 40 CFR 
51.309(d)(10)(i)(A). Because this provision does not call for a summary 
of all pollutants that could contribute to visibility impairment, we do 
not agree that the progress report is inadequate. The initial regional 
haze SIP focused on reducing emissions of sulfur dioxide 
(SO2), nitrogen oxides (NOX), and particulate 
matter (PM) emissions, and New Mexico's progress report summarized the 
changes in emissions in these pollutants from 2008-2012. Even if no 
information on other pollutants was included in the progress report, we 
would consider it reasonable and sufficient if New Mexico's progress 
report only provided a summary of emission reductions for these 
pollutants.
    New Mexico's progress report, however, also provided information on 
other visibility-impairing pollutants. Section 3.5 of the progress 
report discussed New Mexico's baseline emissions inventory for 2002 and 
an estimated emissions inventory for 2008. The 2002 inventory was 
developed by the WRAP for use in the initial WRAP regional haze SIP 
strategy development. The 2008 inventory was based on WRAP inventory 
work for the West-wide Jumpstart Air Quality Modeling Study 
(WestJumpAQMS) and the Deterministic & Empirical Assessment of Smoke's 
Contribution to Ozone (DEASCO3) modeling project efforts. The 
pollutants inventoried were SO2, NOX, 
NH3, VOCs, primary organic aerosol (POA), elemental carbon 
(EC), fine soil, and coarse mass. The inventories were categorized for 
all major visibility-impairing pollutants under major source groupings 
either as anthropogenic or natural. The anthropogenic source 
categorization included point and area sources, on and off-road mobile 
sources, area oil and gas, fugitive and road dust, and anthropogenic 
fire. The natural source categorization included natural fire, wind-
blown dust, and biogenic sources.
    Comment: The progress report presented information on visibility 
levels within section 3.3 of the progress report, which is titled as 
addressing the requirement of 40 CFR 51.309(d)(10)(i)(B). The commenter 
does not consider this presentation as satisfying the requirement of 40 
CFR 51.309(d)(10)(i)(B) concerning emissions because the progress 
report failed to explain how much of the monitored improvements in 
visibility impairment were the result of emission reductions from 
control measures in the New Mexico SIP or from factors outside of the 
SIP. Furthermore, the trends outlined in section 3.5 were seven years 
out of date.
    Response: We agree with the commenter that information on 
visibility levels is not an adequate substitute for the summary of 
emissions that is specifically required by Sec.  51.309(d)(10)(i)(B). 
However, we are not basing our approval of the progress report as 
meeting the requirements of 40 CFR 51.309(d)(10)(i)(B) on the 
information on visibility levels presented in section 3.3 of the 
progress report. The summary of emissions requirement is satisfied for 
the reasons explained in our earlier responses.
    Comment: The goal of the progress report is to document progress 
and changes over the past five years and to make informed decisions on 
that basis. To meet the requirements of 40 CFR 51.309(d)(10)(i)(C), the 
progress report should include information that describes the preceding 
five-year period as closely as possible. The progress report discussed 
the 2005-2009 period. Although information from 2007-2011 was included, 
the EPA should require the use of the most recent data available.
    Response: Although New Mexico used 2005-2009 data to estimate 
current conditions, it also included additional IMPROVE data in its 
progress report. The 2007-2011 visibility information was specifically 
included in Tables 3.3-3.18 of the progress report. We do not agree 
that the information was not addressed such that the requirements of 
the section were not met. Because the progress report was not submitted 
until March 14, 2014, however, there was an understandable lag between 
its drafting, its adoption, and submission. We do not consider the non-
inclusion of visibility data more recent than 2011 to be a basis for 
disapproval. Visibility data for all Class I areas through 2013 were 
available to the public as of the date of the commenter's letter via 
the IMPROVE program's Web site, and the commenter did not argue that 
the more recent data supports disapproval of the progress report.
    Comment: The progress report does not meet 40 CFR 
51.309(d)(10)(i)(D) because it did not use the most up-to-date 
emissions information nor provide sufficient forward projections.
    Response: Section 3.8 of the progress report contains a detailed 
analysis of 2008 emissions from all source types. In addition, Figure 
3.6 of the SIP revision presents SO2 and NOX 
point source emission data for 2008-2012. The year 2012 was the most 
recent emission information covering all types of point sources 
available at the time of the progress report's development. The 
progress report does not include any emissions information for non-
point sources for any year more recent than 2008. However, we note that 
the 2011 National Emissions Inventory (NEI) Version 1.01 was published 
by the EPA in July 2013,\7\ only about 8 months before the State 
submitted the progress report. In light of this, we consider the 
progress report to adequately meet the requirement of 40 CFR 
51.309(d)(10)(i)(D), which calls for an analysis tracking the changes 
``over the past 5 years'' in emissions from ``all sources'' based on 
``the most recent updated emissions inventory.''

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

    Regarding the issue of projected inventories, Sec.  
51.309(d)(10)(i)(D) states that emission estimates must be projected 
forward as necessary and appropriate to account for emissions changes 
during ``the applicable 5-year period.'' This phrase is meant to refer 
to ``the past 5 years,'' a phrase that itself is not clearly defined in 
the rule. The progress report was required to be submitted in 2013 and 
was submitted in February 2014. Thus, a projection for point sources 
would at most have included estimates for 2013. In light of this, we do 
not believe that a projection

[[Page 27130]]

for point sources beyond 2012 is necessary. With regard to non-point 
sources, a projection could have addressed projected-emissions several 
years beyond the 2008 information presented in the progress report; 
however, the SIP focuses primarily on the control of point source 
emissions. With respect to changes in fire-related emissions, 
projections would inherently be highly uncertain in any case. 
Consequently, we do not believe that projections of non-point source 
emissions beyond 2008 were needed in the progress report.
    Comment: The progress report does not meet 40 CFR 
51.309(d)(10)(i)(E) because it drew an unsupported conclusion that no 
anthropogenic emissions within New Mexico limited or impeded progress 
in reducing pollutant emissions or improving visibility. For example, 
White Mountain had visibility degradation.
    Response: We disagree with the comment. 40 CFR 51.309(d)(10)(i)(E) 
requires an assessment of any significant changes in anthropogenic 
emissions within or outside the State that have occurred over the past 
five years that have limited or impeded progress in reducing pollutant 
emissions and improving visibility in Class I areas impacted by the 
State's sources. In its progress report, New Mexico concluded that no 
such changes had occurred. The proposal noted that there have been 
significant reductions in emissions of SO2 and 
NOX from point sources within the State. Also, the State has 
relied on the history of visibility levels at affected Class I areas to 
assess whether there have been changes in emissions that limit or 
impede progress. While we do not consider information on visibility 
levels to be a substitute for the required summary of emissions that is 
exactly required by Sec.  51.309(d)(10)(i)(B), we consider this 
approach to be an acceptable method for making the assessment of 
whether there have been changes in emissions that limit or impede 
progress. Overall visibility at each of the seven Class I areas in New 
Mexico had improved since the baseline period, with the exception of 
visibility at the White Mountain Wilderness Area for the most recent 
period. Specifically, for White Mountain, the five-year average 
deciview trend for the 2007-2011 period showed slightly worse 
visibility (0.2 dv higher) for the 20% worst days, as compared to 
average conditions for 2000-2004. The commenter relied on this 
degradation in visibility at White Mountain to support its argument 
that anthropogenic emissions within New Mexico have limited progress in 
improving visibility. The slight visibility degradation at White 
Mountain, however, was the result of elevated coarse mass levels from 
non-anthropogenic sources in 2011 compared to baseline levels.\8\ 
Overall SO2 and NOX emissions in New Mexico have 
actually been going down, or are at least stable. The proposal also 
indicated that White Mountain showed a 0.3 dv improvement in visibility 
on the 20% best days.\9\
---------------------------------------------------------------------------

    \8\ See 80 FR 67688.
    \9\ The SIP includes this information in Table 3.17 and Table 
3.18.
---------------------------------------------------------------------------

    Comment: The progress report does not meet 40 CFR 
51.309(d)(10)(i)(E) because it failed to address anthropogenic 
emissions outside of New Mexico that may have limited or impeded 
progress in visibility improvement.
    Response: The progress report is required to assess significant 
changes outside the State that have limited or impeded progress, as 
specified by Sec.  51.309(d)(10)(i)(E). As in the case of assessing in-
state emissions, we believe it was acceptable for the State to use 
trends in visibility levels to make this assessment. Visibility 
conditions at the Class I areas are improving, as discussed in response 
to the comment above, and there do not appear to be significant changes 
that would call for explicit discussion. We also note that the State's 
Regional Haze SIP and its participation in the section 309 program 
addressed anthropogenic emissions from outside of the borders that 
limit or impede visibility improvement.
    Comment: The progress report does not meet 40 CFR 
51.309(d)(10)(i)(F) because it cited 2000-2010 visibility monitoring 
data to conclude that New Mexico's approach was sufficient to meet the 
RPGs. The progress report offers little support to show that visibility 
is causally linked to New Mexico's SIP measures rather than to changes 
in natural or out-of-state sources. The EPA should require quantitative 
evidence to show the link between visibility benefits and the SIP 
measures.
    Response: We view the requirement of this section as a qualitative 
assessment that should evaluate emissions and visibility trends, 
including expected emission reductions from measures that have not yet 
become effective. Even though section 3.7 of the progress report 
(titled as addressing the requirement of 40 CFR 51.309(d)(10)(i)(F)) 
cited visibility monitoring data from 2000-2010, visibility data 
through 2011 is presented in other sections of the progress report. In 
particular, tables 3.3-3.18 presented visibility values of the 20% 
worst and 20% best days of periods 2000-2004, 2005-2009, 2006-2010, and 
2001-2011 for each affected Class I area. Table 2.1 of the progress 
report showed the RPGs for each area.
    The five-year average deciview values for the most recent period 
2007-2011 indicated visibility improvement for all Class I areas 
(relative to 2000-2004 baseline period) except White Mountain, which 
was slightly worse by 0.2 dv. It is important to note that White 
Mountain visibility improved in the 2005-2009 and 2006-2010 periods 
compared to the baseline period 2000-2004. The data supports the 
conclusion that the 2007-2011 visibility conditions at White Mountain 
were higher than the 2000-2004 baseline due to elevated coarse mass 
levels in 2011 from high wind events.
    The 2007-2011 visibility conditions at Bandelier and San Pedro 
parks were higher than in the intermediate periods, due to elevated 
particulate organic matter levels in 2011 from impacts of fires, but 
better than in 2000-2004.
    For all the areas, the 2007-2011 visibility levels were better than 
the RPGs for the 20% best days. This is also true for five of the areas 
for the 20% worst days. The commenter did not suggest any particular 
reasons to expect that visibility will degrade in these areas for the 
best/worst days where it is already better than the 2018 RPGs.
    As noted, three Class I sites were not yet meeting the 2018 RPGs 
for the 20% worst days in 2007-2011. The progress report explains that 
in this period White Mountain was adversely affected by coarse mass 
from high wind events, and San Pedro and Bandelier were affected by 
particulate organic matter from natural and anthropogenic fires. In 
2005-2009, these three areas were below or very close to the 2018 RPGs.
    In summary, we conclude that the State's visibility assessment is 
adequate. Wildfires or dust storms might again affect visibility in the 
2018 timeframe, but New Mexico expects further reduction of 
SO2 and NO2 emissions, principally from the 
implementation of Best Available Retrofit Technology (BART) controls. 
These control measures should contribute toward improved visibility 
conditions at all New Mexico Class I areas, including Bandelier, San 
Pedro, and White Mountain for 2018. Further progress will also occur 
through recently adopted or proposed regulatory programs. The State was 
reasonable to rest on these positive overall visibility trends and 
future expectations regarding emission reductions in determining that 
the existing SIP requires no further revision

[[Page 27131]]

to achieve established RPGs. New Mexico demonstrated progress toward 
meeting the RPGs and no substantive revisions to the Regional Haze SIP 
are necessary for the first planning period. We also note that Sec.  
51.309(d)(10)(i)(F) does not impose a requirement for a demonstration 
of a causal linkage between improvements in visibility and measures in 
New Mexico's SIP.
    Comment: The progress report does not meet 40 CFR 
51.309(d)(10)(i)(F) because it did not offer sufficient evaluation of 
the lack-of-progress or backsliding at Class I areas, like White 
Mountain, that indicated degradation in the 2007-2011 time-period 
relative to 2005-2009 values. A more detailed account of visibility 
issues at these Class I areas should be required before concluding that 
the existing SIP is adequate.
    Response: We disagree with this comment. Based on the speciation 
information in Tables 3.3-3.18, the data supports the conclusion that 
dust storms and/or wildfires are responsible for the limited cases of 
degradation in visibility between 2005-2009 and 2007-2011, rather than 
any backsliding on the control of emissions from anthropogenic sources.
    Comment: According to 40 CFR 51.308(d)(1)(B)(vi), RPGs should 
reflect all reductions in the SIP and in any other CAA requirement. 
RPGs for Class I areas impacted by SJGS should be lower. The EPA should 
require the progress report to include a list of Class I areas impacted 
by future reductions from SJGS and clarify that RPGs are those that 
would be consistent with that source's reductions.
    Response: The progress report was prepared with emphasis on New 
Mexico's improvement in meeting established RPGs for 2018. There were 
no changes to the State's RPGs in the progress report nor were there 
any submitted for review as any separate SIP revision. Whether the RPGs 
should be lower is not in the scope of the proposed action. We agree 
that future reductions at SJGS will improve visibility at Class I areas 
inside and outside of New Mexico. Having already approved the RPGs,\10\ 
we noted that with the additional future two-unit shut down and two-
unit selective non-catalytic reduction (SNCR) installation at the SJGS, 
New Mexico emissions will improve on the RPGs in its SIP. New Mexico is 
not impeding other states in meeting analogous RPGs, and the additional 
BART controls will decrease visibility-impairing pollutants more than 
anticipated from the RPGs based on the WRAP modeling for 
NOX, SO2 and PM.

    \10\ The RPGs can be seen in the June 2012 proposed action (77 
FR 36044) which was finalized on November 27, 2012 (77 FR 70693).
---------------------------------------------------------------------------

    New Mexico does not have a progress report requirement to list all 
Class I areas impacted by future reductions from the SJGS. However, 
state and federal technical records for the BART determination at SJGS 
provide information on this area of interest.
    Comment: The commenter requested that the EPA require revisions to 
the progress report to ensure Class I areas in New Mexico and 
surrounding states are on the glide path to achieve natural visibility 
conditions by 2064.
    Response: In the progress report SIP, New Mexico was required to 
assess whether the SIP was sufficient to meet the RPGs that were 
established for the first ten-year planning period. There is no 
requirement for a state to include an assessment of whether a SIP is 
sufficient to ensure that Class I areas (in the State or those in 
nearby states) are on track to meet the uniform rate of progress 
(URP).\11\ The State followed the proper approach in setting the RPGs 
through 2018 by considering the URP and the factors established in 
section 169A of the CAA and in the EPA's Regional Haze Rule at 40 CFR 
51.308(d)(1)(i)(A). In doing so, the RPGs reflected a slower rate of 
progress than the URP for the first planning period. Those established 
RPGs for each Class I area in New Mexico were approved by the EPA in a 
previous action.\12\ Looking forward, New Mexico will be required to 
provide new updated RPGs for 2028 in the next comprehensive regional 
haze SIP revision planning period.
---------------------------------------------------------------------------

    \11\ The URP is the minimum rate of progress needed to achieve 
the CAA goal of natural visibility conditions within sixty years (to 
2064). It represents the slope between baseline visibility 
conditions in 2004 and natural visibility conditions in 2064. The 
URP for each ten-year long-term strategy equals the visibility 
improvement along the glide path for that planning period.
    \12\ The RPGs can be seen in the June 2012 proposed action (77 
FR 36044) which was finalized on November 27, 2012 (77 FR 70693).
---------------------------------------------------------------------------

III. Final Action

    The EPA is approving New Mexico's regional haze progress report SIP 
revision (submitted on March 11, 2014) as meeting the applicable 
regional haze requirements set forth in 40 CFR 51.309(d)(10).\13\ The 
EPA is also approving New Mexico's determination that the current 
regional haze SIP requires no further substantive revision at this time 
in order to achieve established RPGs for 2018 for visibility 
improvement and emission reductions.
---------------------------------------------------------------------------

    \13\ The final action does not pertain to the Albuquerque/
Bernalillo County portion of the SIP in New Mexico. The New Mexico 
Air Quality Control Act (section 74-2-4) authorizes Albuquerque/
Bernalillo County to locally administer and enforce the State Air 
Quality Control Act by providing for a local air quality control 
program, and that entity submitted an initial regional haze SIP for 
that jurisdiction that was separately approved by the EPA (77 FR 
71119, November 29, 2012). The EPA anticipates a separate regional 
haze progress report SIP submittal from this entity.
---------------------------------------------------------------------------

    40 CFR 51.309(d)(10)(i)(A) requires a description of the status of 
implementation of all control measures included in the regional haze 
SIP for achieving RPGs for Class I areas both within and outside the 
State. New Mexico adequately addressed the status of control measures 
in the progress report regional haze SIP as required by the provisions 
under 40 CFR 51.309(d)(10)(i)(A). All major control measures (including 
BART) were identified and the emission reduction strategy behind each 
control was explained. New Mexico included a summary of the 
implementation status associated with each control measure and 
quantified the benefits where possible. In addition, the progress 
report SIP adequately outlined the compliance time-frame for all 
controls.
    40 CFR 51.309(d)(10)(i)(B) requires a summary of the emission 
reductions achieved throughout the State through implementation of 
control measures mentioned in 40 CFR 51.309(d)(10)(i)(A). The progress 
report must identify and estimate emission reductions to date in 
visibility-impairing pollutants from the SIP control measures 
identified for implementation. New Mexico has adequately summarized the 
emission reductions achieved throughout the State in the progress 
report regional haze SIP as required under 40 CFR 51.309(d)(10)(i)(B).
    40 CFR 51.309(d)(10)(i)(C) requires that for each mandatory Class I 
Federal area within the State, the State must assess visibility 
conditions and changes, with values for most impaired and least 
impaired days expressed in terms of five-year averages of these annual 
values. New Mexico has adequately addressed the requirements under 40 
CFR 51.309(d)(10)(i)(C) to include summaries of monitored visibility 
data as required by the Regional Haze Rule.\14\
---------------------------------------------------------------------------

    \14\ For purposes of improved clarity on future reports, we 
recommend that New Mexico include a graph of rolling averages 
similar to what was provided in the guidance example, illustrating 
the uniform glide path. The glide path graphically shows what would 
be a uniform rate of progress, toward meeting the national goal of a 
return to natural visibility conditions by 2064 for each Class I 
area.
---------------------------------------------------------------------------

    40 CFR 51.309(d)(10)(i)(D) requires an analysis tracking the change 
over the

[[Page 27132]]

past five years in emissions of pollutants contributing to visibility 
impairment from all sources and activities within the State. The 
analysis must be based on the most recent updated emissions inventory, 
with estimates projected forward as necessary and appropriate, to 
account for emissions changes during the applicable five-year period. 
New Mexico has adequately addressed the requirements under 40 CFR 
51.309(d)(10)(i)(D) to track changes in emissions of pollutants 
contributing to visibility impairment from all sources and activities 
within the State. The analysis in the progress report was based on 
appropriate data.
    40 CFR 51.309(d)(10)(i)(E) requires an assessment of any 
significant changes in anthropogenic emissions within or outside the 
State that have occurred over the past five years that have limited or 
impeded progress in reducing pollutant emissions and improving 
visibility in Class I areas impacted by the State's sources. New Mexico 
has adequately addressed the requirements under 40 CFR 
51.309(d)(10)(i)(E) to show that the major contributors of 
anthropogenic emissions are being reduced and visibility is improving 
without having limited or impeded progress.
    40 CFR 51.309(d)(10)(i)(F) calls for an assessment of whether the 
current implementation plan elements and strategies in the regional 
haze SIP are sufficient to enable the State, or other states with 
mandatory Federal Class I areas affected by emissions from the State, 
to meet all established RPGs. New Mexico has adequately addressed the 
requirements under 40 CFR 51.309(d)(10)(i)(F). New Mexico referenced 
the improving visibility trends with appropriately supported data with 
a focus on future implementation of BART controls.
    40 CFR 51.309(10)(i)(G) requires a review of the State's visibility 
monitoring strategy and any modifications to the strategy as necessary. 
New Mexico has adequately addressed the sufficiency of the monitoring 
strategy as required by the provisions under 40 CFR 
51.309(d)(10)(i)(G). New Mexico reaffirmed the continued reliance upon 
the IMPROVE monitoring network. New Mexico also explained the 
importance of the IMPROVE monitoring network for tracking visibility 
trends at the Class I areas and identified no expected changes in this 
network.
    Under 40 CFR 51.309(d)(10)(ii), states are required to submit, at 
the same time as the progress report SIP, a determination of the 
adequacy of the existing regional haze SIP and take one of four 
possible actions based on information in the progress report. New 
Mexico stated in the progress report SIP that the current Section 309 
and 309(g) regional haze SIPs are adequate to meet the State's 2018 
RPGs and require no further revision at this time. The EPA is approving 
this negative declaration from New Mexico.

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 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, 
if the choices meet the criteria of the CAA. Accordingly, this action 
merely approves the information and determinations in the State's 
progress report 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 Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, 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 this rulemaking 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 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).
    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 CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by August 14, 2017. 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 the requirements. (See section 307(b)(2).)
