Approval and Promulgation of Implementation Plans; Nevada;
Determination of Attainment for the Clark County 8-Hour Ozone
Nonattainment Area
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: EPA is determining that the Clark County (Nevada) 8-hour ozone
nonattainment area has attained the 1997 8-hour ozone national ambient
air quality standards (NAAQS). This determination is based upon
complete, quality-assured, and certified ambient air monitoring data
that show the area has monitored attainment of the 1997 8-hour ozone
NAAQS for the 2007 to 2009 monitoring period. Preliminary air quality
monitoring data available for 2010 are consistent with continued
attainment. Based on this determination, the obligation for the State
of Nevada to submit an attainment demonstration and associated
reasonably available control measures (RACM), a reasonable further
progress (RFP) plan, contingency measures, and other planning
requirements related to attainment of the 1997 8-hour ozone NAAQS for
the Clark County ozone nonattainment area shall be suspended for as
long as the nonattainment area continues to meet the 1997 8-hour ozone
NAAQS. This action is being taken under the Clean Air Act (CAA).
DATES: This action is effective on May 31, 2011 without further notice,
unless EPA receives adverse comment by April 28, 2011. If EPA receives
adverse comment, we will publish a timely withdrawal in the Federal
Register informing the public that the rule will not take effect.

I. What determination is EPA making?
EPA is determining that the Clark County (Nevada) 8-hour ozone
nonattainment area (``Clark County ozone nonattainment area'') has
attained the 1997 8-hour ozone NAAQS. The Clark County ozone
nonattainment area is composed of a portion of Clark County in
Nevada.\1\ EPA's determination is based upon complete, quality-assured,
and certified ambient air quality monitoring data for the years 2007 to
2009 showing that the Clark County ozone nonattainment area has
monitored attainment of the 1997 8-hour ozone NAAQS. Preliminary air
quality monitoring data available for 2010 are consistent with
continued attainment.
---------------------------------------------------------------------------
\1\ The boundaries of the Clark County ozone nonattainment area
are defined in 40 CFR 81.329. Specifically, the area is defined as:
``That portion of Clark County that lies in hydrographic areas 164A,
164B, 165, 166, 167, 212, 213, 214, 216, 217, and 218 but excluding
the Moapa River Indian Reservation and the Fort Mojave Indian
Reservation.'' The area includes a significant portion of the
unincorporated portions of central and southern Clark County, as
well as the cities of Las Vegas, Henderson, North Las Vegas, and
Boulder City.
---------------------------------------------------------------------------
On March 27, 2008 (73 FR 16436), EPA promulgated a revised 8-hour
ozone standard of 0.075 parts per million (ppm). On January 6, 2010,
EPA again addressed this 2008 revised standard and proposed to set the
primary 8-hour ozone standard within the range of 0.060 to 0.070 ppm,
rather than at 0.075 ppm. EPA is working to complete reconsideration of
the standard and thereafter will proceed with attainment/nonattainment
area designations. This rulemaking relates only to a determination of
attainment for the 1997 8-hour ozone standard and is not affected by
the ongoing process of reconsidering the revised 2008 standard. This
action addresses only the 1997 8-hour ozone standard of 0.08 ppm, and
does not address any subsequently revised 8-hour ozone standard.
II. What is the background for this action?
A. The Clark County Ozone Nonattainment Area
In 1997, EPA revised the health-based NAAQS for ozone, setting it
at 0.08 ppm averaged over an 8-hour timeframe. EPA set the 8-hour ozone
standard based on scientific evidence demonstrating that ozone causes
adverse health effects at lower ozone concentrations and over longer
periods of time, than was understood when the pre-existing 1-hour ozone
standard was set. EPA determined that the 8-hour standard would be more
protective of human health, especially children and adults who are
active outdoors, and individuals with a pre-existing respiratory
disease, such as asthma.
On April 30, 2004 (69 FR 23858), EPA finalized its attainment/
nonattainment designations for areas across the country with respect to
the 8-hour ozone standard. In that action we designated Clark County as
nonattainment and provided that this designation would become effective
on June 15, 2004. Following the April 2004 final rule, the State of
Nevada submitted additional information requesting that the boundaries
of the area to be designated nonattainment be reconsidered. In
response, EPA granted a deferral of the effective date for Clark County
to consider this information. See 69 FR 34076 (June 18, 2004). On
September 17, 2004, EPA reduced the geographic extent of the ozone
nonattainment area to encompass a portion of, but not all of, Clark
County. See 69 FR 55956 (September 17, 2004) and 40 CFR 81.329. In
2005, we published a final rule that we would treat the effective date
of the partial-county nonattainment area designation the same as the
designations for the rest of the country, i.e., June 15, 2004. See 70
FR 71612 (November 29, 2005) and 40 CFR 51.917.
B. Determination of Attainment
Under the provisions of EPA's ozone implementation rule for the
1997 ozone NAAQS (see 40 CFR 51.918), if EPA issues a determination
that an area is attaining the standard (through a rulemaking that
includes public notice and comment), it will suspend the area's
obligations to submit an attainment demonstration, RACM, RFP,
contingency measures and other planning requirements related to
attainment for as long as the area continues to attain. The
determination of attainment is not equivalent to a redesignation. The
State must still meet the statutory requirements for redesignation in
order to be redesignated to attainment.
C. Ambient Air Quality Monitoring Data
Complete, quality-assured, and certified 8-hour ozone air quality
monitoring data for 2007 through 2009, as well as preliminary data
available to date for 2010, show that the Clark County ozone
nonattainment area has attained, and continues to attain, the 1997 8-
hour ozone NAAQS.
III. What is the effect of this action?
As noted, under 40 CFR section 51.918, the effect of today's
determination of attainment is to suspend the obligation to submit
certain planning requirements described above; however, it does not
constitute a redesignation to attainment under section 107(d)(3) of the
CAA. The designation status of the Clark County ozone nonattainment
area remains nonattainment for the 1997 8-hour ozone NAAQS until such
time as EPA determines that the area meets the CAA requirements for
redesignation to attainment, including an approved maintenance plan.
A. Determination of Attainment
EPA is determining that the Clark County ozone nonattainment area
is attaining the 1997 8-hour ozone NAAQS. In accordance with 40 CFR
51.918, based on this determination, the obligation under the CAA for
the State of Nevada to submit an attainment demonstration and RACM, RFP
plan, contingency measures, and any other planning requirements related
to attainment of the 1997 8-hour ozone NAAQS for the Clark County ozone
nonattainment area is suspended for so long as the area continues to
attain the 1997 8-hour ozone NAAQS. Although these requirements are
suspended, EPA is not precluded from acting upon these elements, if
Nevada submits them for EPA review and approval.
The effect of this determination is to:
(1) Suspend the requirements to submit an attainment demonstration,
RACM, RFP plan, contingency measures, and any other planning
requirements related to attainment of the 1997 8-hour ozone NAAQS;
(2) Continue until such time, if any, that EPA (i) redesignates the
area to attainment at which time those requirements no longer apply, or
(ii) subsequently determines that the area has violated the 1997 8-hour
ozone NAAQS;
(3) Be separate from, and not influence or otherwise affect, any
future designation determination or requirements for the area based on
any new or revised ozone NAAQS; and
(4) Remain in effect regardless of whether EPA designates this area
as a nonattainment area for purposes of any new or revised ozone NAAQS.
If EPA subsequently determines, after notice-and-comment
rulemaking, that the Clark County ozone nonattainment area has violated
the 1997 8-hour ozone NAAQS, the basis for the suspension of the
specific requirements, set forth at 40 CFR 51.918, would no longer
exist, and the Clark County ozone nonattainment area would thereafter
have to address applicable requirements.
[[Page 17345]]
B. Subpart 1 Designation
Under the implementation rule for the 1997 8-hour ozone standard,
EPA designated certain areas under title I, part D, subpart 1 of the
CAA (subpart 1) if they had a 1-hour design value below 0.121 ppm. As
discussed above, in 2004, EPA designated a portion of Clark County
nonattainment under subpart 1 for the 1997 8-hour ozone standard. In
June 2007, the United States Court of Appeals for the District of
Columbia Circuit (DC Circuit Court) vacated the portion of the 1997
ozone implementation rule that allowed areas to be designated under
subpart 1. On January 16, 2009 (74 FR 2936), EPA published a proposed
rule to address, among other issues, the DC Circuit Court vacatur of
the classification system that EPA used to designate a subset of
initial 1997 8-hour ozone nonattainment areas under subpart 1. In that
rulemaking, EPA proposed that all areas designated nonattainment for
the 1997 8-hour ozone NAAQS under subpart 1 would be classified as
subpart 2 areas (hereafter referred to as the ``Subpart 1/Subpart 2
1997 8-Hour Ozone Rulemaking''). The Clark County ozone nonattainment
area is among those areas that would be classified under subpart 2 if
EPA's proposal is finalized. EPA has not yet completed its final
rulemaking action for the Subpart 1/Subpart 2 1997 8-Hour Ozone
Rulemaking. When the Subpart 1/Subpart 2 1997 8-Hour Ozone Rulemaking
is finalized, and if the Clark County ozone nonattainment area
continues in attainment for the 1997 8-hour ozone NAAQS, EPA will
address in a future rulemaking the consequences of a determination of
attainment for any requirements to which the Clark County ozone
nonattainment area becomes subject as a result of its reclassification.
If, after the Clark County ozone nonattainment area is classified under
subpart 2, EPA determines in a future rulemaking that the Clark County
ozone nonattainment area continues to be in attainment, then the
obligation to submit the applicable attainment planning-related
requirements for its new classification would be suspended in
accordance with 40 CFR 51.918.
IV. What is EPA's analysis of the relevant air quality data?
A determination of whether an area's air quality meets the ozone
NAAQS is generally based upon the most recent three years of complete,
quality-assured data gathered at established National Air Monitoring
Stations (``NAMS'') or State and Local Air Monitoring Stations
(``SLAMS'') in the nonattainment area and entered into the EPA Air
Quality System (``AQS'') database. Data from air monitors operated by
State/local agencies in compliance with EPA monitoring requirements
must be submitted to the EPA AQS database. Heads of monitoring agencies
annually certify that these data are accurate to the best of their
knowledge. Accordingly, EPA relies primarily on data in its AQS
database when determining the attainment status of areas. See 40 CFR
50.10; 40 CFR part 50, appendix I; 40 CFR part 53; 40 CFR part 58,
appendices A, C, D and E. All data are reviewed to determine the area's
air quality status in accordance with 40 CFR part 50, appendix I.
Under EPA regulations at 40 CFR part 50, the 1997 8-hour ozone
standard is attained at a site when the 3-year average of the annual
fourth-highest daily maximum 8-hour average ozone concentrations at an
ozone monitor is less than or equal to 0.08 ppm. See 40 CFR 50.10. This
3-year average is referred to as the design value. When the design
value is less than or equal to 0.084 ppm (based on the rounding
convention in 40 CFR part 50, appendix I) at each monitoring site
within the area, then the area is meeting the NAAQS. The data
completeness requirement is met when the three-year average percent of
days with valid ambient monitoring data is greater than 90%, and no
single year has less than 75% data completeness as determined in
Appendix I of 40 CFR Part 50.
The Clark County Department of Air Quality & Environmental
Management (DAQEM) is responsible for monitoring ambient air quality
within Clark County. DAQEM submits monitoring network plan reports to
EPA on an annual basis. These reports discuss the status of the air
monitoring network, as required under 40 CFR part 58. Beginning in
2007, EPA reviews these annual plans for compliance with the applicable
reporting requirements in 40 CFR 58.10. With respect to ozone, we have
found DAQEM's annual network plans to meet the applicable requirements
under 40 CFR part 58. See EPA letters to DAQEM concerning DAQEM's
annual network plan reports for years 2007, 2008, 2009 and 2010.
Furthermore, we concluded in our Technical System Audit Report
(February 2010) that Clark County DAQEM's ambient air monitoring
network currently meets or exceeds the requirements for the minimum
number of monitoring sites designated as State and local air monitoring
stations (SLAMS) for all of the criteria pollutants, and that all of
the monitoring sites are properly located with respect to monitoring
objectives, spatial scales and other site criteria. Also, DAQEM
annually certifies that the data it submits to AQS are complete and
quality-assured. See, e.g., letter dated April 14, 2010, from Lewis
Wallenmeyer, Director, DAQEM, to Jared Blumenfeld, EPA Region IX
Regional Administrator.
Clark County DAQEM operated 12 ozone SLAMS monitoring sites over
the 2007-2010 period within the Clark County ozone nonattainment area:
Apex (Apex Valley), Boulder City (City of Boulder City), Craig Road
(City of North Las Vegas), J.D. Smith School (City of North Las Vegas),
Jean (City of Jean, south of Las Vegas), Joe Neal (northwest Las
Vegas), Lone Mountain (northwest Las Vegas), Orr School (central-
southeast Las Vegas), Paul Meyer Park (southwest Las Vegas), Palo Verde
School (west Las Vegas), Walter Johnson (west Las Vegas), and
Winterwood (southeast Las Vegas). All 12 sites monitor ozone
concentrations on a continuous basis using ultraviolet absorption
monitors.\2\ The spatial scale and monitoring objective of most of
DAQEM's ozone monitoring sites are ``neighborhood'' and ``population
exposure,'' respectively. The exceptions are the Apex and Jean sites,
whose spatial scale and monitoring objective is ``regional'' and
``regional transport,'' respectively, and the Joe Neal site, whose
spatial scale is ``neighborhood'' and monitoring objective is ``highest
concentration.'' See Clark County DAQEM's Annual Network Plan Report
(June 2010).
---------------------------------------------------------------------------
\2\ DAQEM operates Federal equivalent method (FEM) monitors for
ozone. Specifically, API 400 Series ultraviolet absorption monitors.
See ``Annual Network Plan Report'', page 13, June 2010. These
monitoring devices have an EPA designation number EQOA-0992-087. See
EPA ``List of Designated Reference and Equivalent Methods'', page
27, February 1, 2011, available at: http://www.epa.gov/ttn/amtic/criteria.html.
---------------------------------------------------------------------------
Consistent with the requirements contained in 40 CFR part 50, EPA
has reviewed the ozone ambient air monitoring data for the monitoring
period from 2007 through 2009 collected at the monitoring sites
discussed above, as recorded in AQS. On the basis of that review, EPA
has concluded that this area attained the 1997 8-hour ozone NAAQS based
on data for the 2007-2009 ozone seasons. Table 1 shows the ozone design
values for the Clark County ozone nonattainment area monitors based on
2007-2009 ambient air quality monitoring data. Preliminary data
available for 2010, summarized in table
[[Page 17346]]
2, are also consistent with continued attainment.\3\
---------------------------------------------------------------------------
\3\ For 2010, DAQEM has reported three calendar quarters of data
for Apex, Boulder City and Craig Road. Lone Mountain and Orr School
monitors closed in April, 2010. The rest of the monitoring stations
in the Clark County ozone nonattainment area reflect four quarters
of monitoring data for 2010.

EPA's review of these data indicates that the Clark County ozone
nonattainment area has met the 1997 8-hour ozone NAAQS. Preliminary air
quality monitoring data available for 2010 are consistent with
continued attainment.
V. EPA's Final Action
EPA is determining that the Clark County (Nevada) 8-hour ozone
nonattainment area has attained the 1997 8-hour ozone NAAQS based on
2007-2009 complete, quality-assured, and certified ambient air quality
monitoring data. Preliminary data available to date for 2010 are
consistent with continued attainment. As provided in 40 CFR 51.918,
this determination of attainment suspends the requirements for the
State of Nevada to submit, for the Clark County ozone nonattainment
area, an attainment demonstration and associated RACM, RFP plan,
contingency measures, and any other planning requirements related to
attainment of the 1997 8-hour ozone NAAQS as long as the area continues
to attain the 1997 8-hour ozone NAAQS.
We are publishing this rule without prior proposal because the
Agency views this as a noncontroversial action and anticipates no
adverse comments. However, in the proposed rules section of this
Federal Register publication, EPA is publishing a separate document
that will serve as the proposal should adverse comments be filed. This
action will be effective May 31, 2011, without further notice unless
the EPA receives relevant adverse comments by April 28, 2011.
If we receive such comments, then we will publish a document
withdrawing the final rule and informing the public that the rule will
not take effect. All public comments received will then be addressed in
a subsequent final rule based on the proposed rule. We will not
institute a second comment period. Parties interested in commenting
should so at this time. If no such comments are received, the public is
advised that this rule will be effective on May 31, 2011 and no further
action will be taken on the proposed rule.
VI. Statutory and Executive Order Reviews
This action makes a determination of attainment based on air
quality and suspends certain 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.);
[[Page 17347]]
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 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 determination that the Clark County ozone
nonattainment area has attained the 1997 8-hour ozone NAAQS 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 May 31, 2011. 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. Parties with objections to this direct final
rule are encouraged to file a comment in response to the parallel
notice of proposed rulemaking for this action published in the proposed
rules section of today's Federal Register, rather than file an
immediate petition for judicial review of this direct final rule, so
that EPA can withdraw this direct final rule and address the comment in
the proposed rulemaking. This action may not be challenged later in
proceedings to enforce its requirements. (See section 307(b)(2).)
