ACTION: Final rule. AGENCY: tkelley on DSK3SPTVN1PROD with RULES VerDate Sep<11>2014 16:42 Oct 03, 2014 Jkt 235001 Table of Contents I. Proposed Actions II. Public Comments III. Final Action IV. Statutory and Executive Order Reviews I. Proposed Actions The Environmental Protection Agency (EPA) is taking final action to approve a revision to the Nevada state implementation plan that provides for the maintenance of the national ambient air quality standard for particulate matter with an aerodynamic diameter less than or equal to a nominal ten micrometers (PM10) in Las Vegas Valley for the next ten years and to approve the related motor vehicle emissions budgets. Based in part on the approval of the PM10 maintenance plan, EPA is also taking final action to grant the State of Nevada’s request for redesignation of Las Vegas Valley to attainment for the PM10 standard. Consistent with the assumptions of the maintenance plan, EPA is approving revisions to certain local fugitive dust rules to ensure their continued applicability after redesignation of the area to attainment. Lastly, EPA is taking final action to delete the area designation for Las Vegas Valley for the revoked national standard for total suspended particulate because the designation is no longer necessary. DATES: This rule is effective on November 5, 2014. ADDRESSES: EPA has established a docket for this action under Docket ID Number EPA–R09–OAR–2013–0735. Generally, documents in the docket for this action are available electronically at www.regulations.gov and in hard copy at EPA Region IX, 75 Hawthorne Street, San Francisco, California. While all documents in the docket are listed at www.regulations.gov, some information may be publicly available only at the hard copy location (e.g., copyrighted material, large maps), and some may not be publicly available in either location (e.g., confidential business information or ‘‘CBI’’).

FOR FURTHER INFORMATION CONTACT: Karina O’Connor, Air Planning Office SUMMARY: (AIR–2), U.S. Environmental Protection Agency, Region IX, (775) 434–8176, oconnor.karina@epa.gov. SUPPLEMENTARY INFORMATION: Throughout this document, ‘‘we,’’ ‘‘us,’’ or ‘‘our’’ refer to EPA. This SUPPLEMENTARY INFORMATION section is arranged as follows: On July 21, 2014 (79 FR 42258), under Clean Air Act (CAA or ‘‘Act’’) section 110(k)(3), EPA proposed to approve a submittal from the Nevada Division of Environmental Protection (NDEP) dated September 7, 2012 of the Redesignation Request and Maintenance Plan for Particulate Matter (PM10), Clark County, Nevada (August 2012) (‘‘Las Vegas Valley PM10 Maintenance Plan’’) as a revision to the Nevada state implementation plan (SIP). In so doing, we found that the Las Vegas Valley PM10 Maintenance Plan adequately demonstrates that the area will maintain the PM10 national ambient air quality standard (NAAQS or ‘‘standard’’) for 10 years beyond redesignation and includes sufficient contingency provisions to promptly correct any violation of the PM10 standard which occurs after redesignation and thereby meets the requirements for maintenance plans under CAA section 175A. We also proposed to approve the motor vehicle emissions budgets (MVEBs) in the Las Vegas Valley PM10 Maintenance Plan because we found they meet the applicable transportation conformity requirements under 40 CFR 93.118(e). In our July 21, 2014 proposed rule, under CAA section 107(d)(3)(D), we proposed to grant NDEP’s request to redesignate the Las Vegas Valley PM10 nonattainment area from ‘‘nonattainment’’ to ‘‘attainment’’ for the PM10 standard. We proposed to do so based on our conclusion that the Las Vegas Valley has attained the PM10 standard; 1 that the relevant portions of the Nevada SIP are fully approved; that the improvement in air quality is due to permanent and enforceable emissions reductions; that the State of Nevada has met all of the requirements applicable to 1 In our proposed approval, EPA stated that ‘‘SLAMS data for 2014 are not yet available . . . but will be reviewed prior to final action to ensure that they are consistent with continued attainment.’’ 79 FR at 42263. We have now reviewed 2014 data, submitted to AQS as of September 12, 2014, and have found it to be consistent with continued attainment. PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 the Las Vegas Valley PM10 nonattainment area with respect to section 110 and part D of the CAA; and, based on our proposed approval as described above, that the Las Vegas Valley PM10 Maintenance Plan meets the requirements for maintenance plans under section 175A of the CAA; and that, therefore, the State of Nevada has met the criteria for redesignation under CAA section 107(d)(3)(E) for the Las Vegas Valley PM10 nonattainment area. Next, we proposed to approve certain fugitive dust rules (i.e., Clark County Air Quality Regulations sections 41, and 90 through 93) that Clark County has amended to ensure their continued applicability after the area is redesignated to attainment and that NDEP submitted to us (on May 27, 2014) as a revision to the Nevada SIP. Lastly, we proposed to delete the area designation for Las Vegas Valley for the revoked NAAQS for total suspended particulate. Please see our July 21, 2014 proposed rule for a detailed discussion of the background for these actions, and the rationale for approval of the Las Vegas Valley PM10 Maintenance Plan, for granting NDEP’s request for redesignation of Las Vegas Valley to attainment, for approving Clark County’s amended fugitive dust rules, and for deleting the TSP designation for Las Vegas Valley. II. Public Comments Our July 21, 2014 proposed rule provided a 30-day public comment period, which closed on August 20, 2014. We received no comments on our proposal during this period. III. Final Action Under CAA section 110(k)(3), and for the reasons set forth in our July 21, 2014 proposed rule, EPA is taking final action to approve NDEP’s submittal dated September 7, 2012 of the Redesignation Request and Maintenance Plan for Particulate Matter (PM10), Clark County, Nevada (August 2012) (‘‘Las Vegas Valley PM10 Maintenance Plan’’) as a revision to the Nevada SIP. EPA finds that the maintenance demonstration showing how the area will continue to attain the 24-hour PM10 NAAQS for 10 years beyond redesignation, and the contingency provisions describing the actions that Clark County will take in the event of a future monitored violation, meet all applicable requirements for maintenance plans and related contingency provisions in CAA section 175A. EPA is also finding adequate and approving the motor vehicle emissions budgets in the Las Vegas Valley PM10 Maintenance Plan E:\FR\FM\06OCR1.SGM 06OCR1 Federal Register / Vol. 79, No. 193 / Monday, October 6, 2014 / Rules and Regulations (i.e., 141.14 tons per day in 2008, 2015, and 2023) because we find they meet the applicable transportation conformity requirements under 40 CFR 93.118(e). Second, under CAA section 107(d)(3)(D), we are taking final action to grant NDEP’s request, which accompanied the submittal of the maintenance plan, to redesignate the Las Vegas Valley PM10 nonattainment area to attainment for the 24-hour PM10 NAAQS. We are doing so based on our conclusion that the area has met the five criteria for redesignation under CAA section 107(d)(3)(E). Our conclusion in this regard is in turn based on our determination that the area has attained the 24-hour PM10 NAAQS, that relevant portions of the Nevada SIP are fully approved, that the improvement in air quality is due to permanent and enforceable reductions in emissions, that Nevada has met all requirements applicable to the Las Vegas Valley PM10 nonattainment area with respect to section 110 and part D of the CAA, and based on our approval as part of this action of the Las Vegas Valley PM10 Maintenance Plan. Our determination that the area has attained the 24-hour PM10 NAAQS is based in part on our concurrence with Clark County DAQ that the exceedances monitored in Las Vegas Valley on July 3, 2011 were caused by a high wind exceptional event and our related exclusion of the exceedances from the attainment determination. Third, EPA is taking final action to approve revisions to Clark County fugitive dust rules sections 41, and 90 through 93 that were submitted on May 27, 2014 as a revision to the Nevada SIP because we find that they ensure continued implementation of the rules after redesignation of Las Vegas Valley to attainment and because they meet all other applicable requirements.2 Lastly, EPA is taking final action to delete the area designation for Las Vegas Valley for the revoked national standard for total suspended particulate because the designation is no longer necessary. IV. Statutory and Executive Order Reviews tkelley on DSK3SPTVN1PROD with RULES Under the CAA, redesignation of an area to attainment and the accompanying approval of a maintenance plan under section 2 Approval of Clark County amended sections 41, and 90 through 93 will supersede the following existing rules in the applicable Nevada SIP: Section 41 as approved at 46 FR 43141 (August 27, 1981); section 90 as approved at 71 FR 63250 (October 30, 2006); section 91 as approved at 69 FR 32272 (June 9, 2004); section 92 as approved at 71 FR 63250 (October 30, 2006); and section 93 as approved at 71 FR 63250 (October 30, 2006). VerDate Sep<11>2014 16:42 Oct 03, 2014 Jkt 235001 107(d)(3)(E) are actions that affect the status of a geographical area and do not impose any additional regulatory requirements on sources beyond those imposed by State law. Redesignation to attainment does not in and of itself create any new requirements, but rather results in the applicability of requirements contained in the CAA for areas that have been redesignated to attainment. Moreover, 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, these actions merely approve a State plan and redesignation request as meeting Federal requirements and do not impose additional requirements beyond those by State law. For these reasons, these actions: • Are 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 Executive Order 13563 (76 FR 3821, January 21, 2011); • Do not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); • Are 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.); • Do 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); • Do not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • Are not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • Are not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); • Are 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 • Do not provide EPA with the discretionary authority to address disproportionate human health or environmental effects with practical, appropriate, and legally permissible methods under Executive Order 12898 (59 FR 7629, February 16, 1994). PO 00000 Frm 00023 Fmt 4700 Sfmt 4700 60079 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. Nonetheless, EPA has discussed the action with the one Tribe, the Las Vegas Paiute Tribe, located within the Las Vegas Valley PM10 nonattainment area. 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 CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by December 5, 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)).

Approval of Implementation Plans and Designation of Areas for Air
Quality Planning Purposes; Las Vegas Valley, Nevada; Redesignation to
Attainment for PM10

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final
action to approve a revision to the Nevada state implementation plan
that provides for the maintenance of the national ambient air quality
standard for particulate matter with an aerodynamic diameter less than
or equal to a nominal ten micrometers (PM10) in Las Vegas
Valley for the next ten years and to approve the related motor vehicle
emissions budgets. Based in part on the approval of the PM10
maintenance plan, EPA is also taking final action to grant the State of
Nevada's request for redesignation of Las Vegas Valley to attainment
for the PM10 standard. Consistent with the assumptions of
the maintenance plan, EPA is approving revisions to certain local
fugitive dust rules to ensure their continued applicability after
redesignation of the area to attainment. Lastly, EPA is taking final
action to delete the area designation for Las Vegas Valley for the
revoked national standard for total suspended particulate because the
designation is no longer necessary.

DATES: This rule is effective on November 5, 2014.

ADDRESSES: EPA has established a docket for this action under Docket ID
Number EPA-R09-OAR-2013-0735. Generally, documents in the docket for
this action are available electronically at www.regulations.gov and in
hard copy at EPA Region IX, 75 Hawthorne Street, San Francisco,
California. While all documents in the docket are listed at
www.regulations.gov, some information may be publicly available only at
the hard copy location (e.g., copyrighted material, large maps), and
some may not be publicly available in either location (e.g.,
confidential business information or ``CBI''). To inspect the hard copy

I. Proposed Actions

On July 21, 2014 (79 FR 42258), under Clean Air Act (CAA or
``Act'') section 110(k)(3), EPA proposed to approve a submittal from
the Nevada Division of Environmental Protection (NDEP) dated September
7, 2012 of the Redesignation Request and Maintenance Plan for
Particulate Matter (PM10), Clark County, Nevada (August 2012) (``Las
Vegas Valley PM10 Maintenance Plan'') as a revision to the
Nevada state implementation plan (SIP). In so doing, we found that the
Las Vegas Valley PM10 Maintenance Plan adequately
demonstrates that the area will maintain the PM10 national
ambient air quality standard (NAAQS or ``standard'') for 10 years
beyond redesignation and includes sufficient contingency provisions to
promptly correct any violation of the PM10 standard which
occurs after redesignation and thereby meets the requirements for
maintenance plans under CAA section 175A. We also proposed to approve
the motor vehicle emissions budgets (MVEBs) in the Las Vegas Valley
PM10 Maintenance Plan because we found they meet the
applicable transportation conformity requirements under 40 CFR
93.118(e).
In our July 21, 2014 proposed rule, under CAA section 107(d)(3)(D),
we proposed to grant NDEP's request to redesignate the Las Vegas Valley
PM10 nonattainment area from ``nonattainment'' to
``attainment'' for the PM10 standard. We proposed to do so
based on our conclusion that the Las Vegas Valley has attained the
PM10 standard; \1\ that the relevant portions of the Nevada
SIP are fully approved; that the improvement in air quality is due to
permanent and enforceable emissions reductions; that the State of
Nevada has met all of the requirements applicable to the Las Vegas
Valley PM10 nonattainment area with respect to section 110
and part D of the CAA; and, based on our proposed approval as described
above, that the Las Vegas Valley PM10 Maintenance Plan meets
the requirements for maintenance plans under section 175A of the CAA;
and that, therefore, the State of Nevada has met the criteria for
redesignation under CAA section 107(d)(3)(E) for the Las Vegas Valley
PM10 nonattainment area.
---------------------------------------------------------------------------

\1\ In our proposed approval, EPA stated that ``SLAMS data for
2014 are not yet available . . . but will be reviewed prior to final
action to ensure that they are consistent with continued
attainment.'' 79 FR at 42263. We have now reviewed 2014 data,
submitted to AQS as of September 12, 2014, and have found it to be
consistent with continued attainment.
---------------------------------------------------------------------------

Next, we proposed to approve certain fugitive dust rules (i.e.,
Clark County Air Quality Regulations sections 41, and 90 through 93)
that Clark County has amended to ensure their continued applicability
after the area is redesignated to attainment and that NDEP submitted to
us (on May 27, 2014) as a revision to the Nevada SIP.
Lastly, we proposed to delete the area designation for Las Vegas
Valley for the revoked NAAQS for total suspended particulate.
Please see our July 21, 2014 proposed rule for a detailed
discussion of the background for these actions, and the rationale for
approval of the Las Vegas Valley PM10 Maintenance Plan, for
granting NDEP's request for redesignation of Las Vegas Valley to
attainment, for approving Clark County's amended fugitive dust rules,
and for deleting the TSP designation for Las Vegas Valley.

II. Public Comments

Our July 21, 2014 proposed rule provided a 30-day public comment
period, which closed on August 20, 2014. We received no comments on our
proposal during this period.

III. Final Action

Under CAA section 110(k)(3), and for the reasons set forth in our
July 21, 2014 proposed rule, EPA is taking final action to approve
NDEP's submittal dated September 7, 2012 of the Redesignation Request
and Maintenance Plan for Particulate Matter (PM10), Clark County,
Nevada (August 2012) (``Las Vegas Valley PM10 Maintenance
Plan'') as a revision to the Nevada SIP. EPA finds that the maintenance
demonstration showing how the area will continue to attain the 24-hour
PM10 NAAQS for 10 years beyond redesignation, and the
contingency provisions describing the actions that Clark County will
take in the event of a future monitored violation, meet all applicable
requirements for maintenance plans and related contingency provisions
in CAA section 175A. EPA is also finding adequate and approving the
motor vehicle emissions budgets in the Las Vegas Valley PM10
Maintenance Plan

[[Page 60079]]

(i.e., 141.14 tons per day in 2008, 2015, and 2023) because we find
they meet the applicable transportation conformity requirements under
40 CFR 93.118(e).
Second, under CAA section 107(d)(3)(D), we are taking final action
to grant NDEP's request, which accompanied the submittal of the
maintenance plan, to redesignate the Las Vegas Valley PM10
nonattainment area to attainment for the 24-hour PM10 NAAQS.
We are doing so based on our conclusion that the area has met the five
criteria for redesignation under CAA section 107(d)(3)(E). Our
conclusion in this regard is in turn based on our determination that
the area has attained the 24-hour PM10 NAAQS, that relevant
portions of the Nevada SIP are fully approved, that the improvement in
air quality is due to permanent and enforceable reductions in
emissions, that Nevada has met all requirements applicable to the Las
Vegas Valley PM10 nonattainment area with respect to section
110 and part D of the CAA, and based on our approval as part of this
action of the Las Vegas Valley PM10 Maintenance Plan. Our
determination that the area has attained the 24-hour PM10
NAAQS is based in part on our concurrence with Clark County DAQ that
the exceedances monitored in Las Vegas Valley on July 3, 2011 were
caused by a high wind exceptional event and our related exclusion of
the exceedances from the attainment determination.
Third, EPA is taking final action to approve revisions to Clark
County fugitive dust rules sections 41, and 90 through 93 that were
submitted on May 27, 2014 as a revision to the Nevada SIP because we
find that they ensure continued implementation of the rules after
redesignation of Las Vegas Valley to attainment and because they meet
all other applicable requirements.\2\
---------------------------------------------------------------------------

\2\ Approval of Clark County amended sections 41, and 90 through
93 will supersede the following existing rules in the applicable
Nevada SIP: Section 41 as approved at 46 FR 43141 (August 27, 1981);
section 90 as approved at 71 FR 63250 (October 30, 2006); section 91
as approved at 69 FR 32272 (June 9, 2004); section 92 as approved at
71 FR 63250 (October 30, 2006); and section 93 as approved at 71 FR
63250 (October 30, 2006).
---------------------------------------------------------------------------

Lastly, EPA is taking final action to delete the area designation
for Las Vegas Valley for the revoked national standard for total
suspended particulate because the designation is no longer necessary.

IV. Statutory and Executive Order Reviews

Under the CAA, redesignation of an area to attainment and the
accompanying approval of a maintenance plan under section 107(d)(3)(E)
are actions that affect the status of a geographical area and do not
impose any additional regulatory requirements on sources beyond those
imposed by State law. Redesignation to attainment does not in and of
itself create any new requirements, but rather results in the
applicability of requirements contained in the CAA for areas that have
been redesignated to attainment. Moreover, 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, these actions merely approve a State plan
and redesignation request as meeting Federal requirements and do not
impose additional requirements beyond those by State law. For these
reasons, these actions:
Are 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 Executive Order 13563 (76 FR
3821, January 21, 2011);
Do not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
Are 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.);
Do 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);
Do not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Are not an economically significant regulatory action
based on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
Are not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Are 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
Do not provide EPA with the discretionary authority to
address disproportionate human health or environmental effects with
practical, appropriate, 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. Nonetheless, EPA has
discussed the action with the one Tribe, the Las Vegas Paiute Tribe,
located within the Las Vegas Valley PM10 nonattainment area.
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 CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by December 5, 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)).
