I. Summary of Today's Actions

    We are approving the PM-10 State Implementation Plan for Clark 
County (``Clark County Serious Area Plan'' or ``Plan''), submitted on 
July 23, 2001.\1\ The Plan addresses attainment of the annual and 24-
hour PM-10 standards.\2\ This action is based on our determination that 
this Plan complies with the CAA requirements for serious PM-10 
nonattainment area plans.
---------------------------------------------------------------------------

    \1\ On November 19, 2002, the Nevada Division of Environmental 
Protection submitted to EPA an amendment to the Plan adopted by the 
Clark County Board of Commissioners on November 19, 2002. The 
amendment establishes new deadlines for SIP commitments concerning 
revisions to Sections 90 through 94 and adds documentation on 
adopted local ordinances for fireplaces and woodstoves as Appendix R 
of the Plan. EPA approved these ordinances in a separate action. 68 
FR 52838 (Sept. 8, 2003).
    \2\ PM-10 is particulate matter with an aerometric diameter of 
less than or equal to a nominal 10 micrometers. There are two 
separate NAAQS for PM-10, an annual standard of 50 [mu]g/m\3\ and a 
24-hour standard of 150 [mu]g/m\3\.
---------------------------------------------------------------------------

    First, we are approving the following specific elements of the 
Plan:
     A demonstration that the Plan provides for implementation 
of best available control measures (BACM); \3\
---------------------------------------------------------------------------

    \3\ Because the demonstration of BACM subsumes the demonstration 
of Reasonably Available Control Measures (RACM), a separate analysis 
to determine if the measures represent a RACM level of control is 
not necessary. The BACM demonstration, therefore, is also a finding 
that the Plan provides for the implementation of RACM as required 
under CAA sections 173(c)(1) and 189(a)(1)(C).

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

[[Page 32274]]

     An emissions inventory;
     A demonstration of attainment of the annual standard by 
the CAA deadline of December 31, 2001 and a demonstration that 
attainment of the 24-hour standard by December 31, 2001 is 
impracticable;
     A demonstration that attainment of the 24-hour standard 
will occur by the most expeditious alternative date practicable, in 
this case, December 31, 2006;
     A demonstration that the Plan includes to our satisfaction 
the most stringent measures (MSM) found in the implementation plan of 
another state or achieved in practice in another state and that can be 
feasibly implemented in the area;
     A demonstration that major sources of PM-10 precursors 
such as nitrogen oxides and sulfur dioxide do not significantly 
contribute to violations of the PM-10 standards;
     A demonstration that the Plan provides for reasonable 
further progress and quantitative milestones;
     Transportation conformity motor vehicle emissions budgets; 
and
     Contingency measures.
    We are also approving the County's fugitive dust rules (Sections 90 
through 94 and portions of Section 0),\4\ as well as specific 
commitments by the County and local jurisdictions within the County to 
implement the Plan and perform other activities. As explained in our 
proposed approval, we are finding that the Plan and these rules comply 
with CAA sections 110(a) and 189(b)(1)(B).
---------------------------------------------------------------------------

    \4\ The Plan included the November 16, 2000, versions of these 
rules. On October 24, 2002, the Nevada Division of Environmental 
Protection submitted to EPA revised versions of Clark County 
Sections 90 through 93, dated November 20, 2001, which supersede the 
earlier versions submitted with the Plan. It is this 2001 version of 
Sections 90 through 93 that we are approving in today's action. The 
versions of Section 94 and the portions of Section 0 being approved 
are the November 16, 2000 versions. The County has since adopted 
revisions to these rules and EPA will review and act on these 
changes in a separate rulemaking.
---------------------------------------------------------------------------

    This action also grants Nevada's request to extend the attainment 
date for the 24-hour PM-10 standard from December 31, 2001 to December 
31, 2006. This approval is based on our determination that the State 
has met the CAA's criteria for granting such extensions.
    This preamble describes our actions on the Clark County Serious 
Area Plan. We have not repeated the evaluation of the Plan that we 
provided in the proposal for today's action. See 68 FR 2954, January 
22, 2003.

II. Public Comments and EPA Responses

    EPA's proposed action provided a 30-day public comment period. 
During this period, we received comments from the following parties:

1. Jennifer Anderson, Sierra Club; letter dated February 21, 2003.
2. Robert Hall, Nevada Environmental Coalition, Inc.; letter dated 
February 21, 2003.

III. Background to Today's Action

A. Prior PM Planning Activities in Clark County

    The 1977 Amendments to the CAA required States to revise their SIPs 
for all areas that did not meet the NAAQS. At that time, EPA's 
particulate matter NAAQS were measured in terms of total suspended 
particulates (TSP). The Las Vegas Valley was designated nonattainment 
for TSP. As a result, Nevada submitted, and EPA approved, a 
nonattainment area plan and a series of revisions with state and local 
control measures. See 46 FR 21758 (April 14, 1981), 46 FR 43141 (August 
27, 1981) and 47 FR 26386 (June 18, 1982).
    In 1987, EPA promulgated NAAQS for PM-10, 52 FR 24643 (July 1, 
1987), and the approach by which areas would be designated. 52 FR 24672 
(July 1, 1987). In accordance with these rulemakings, EPA categorized 
areas based on the likelihood that the SIP existing at the time would 
need to be revised to meet the PM-10 standards. 52 FR 29383 (August 7, 
1987). Clark County was placed in ``Group I'', meaning EPA found there 
was a strong likelihood that the area would violate the PM-10 NAAQS and 
that SIP revisions would be required. Id.; see also 55 FR 45799 
(October 31, 1990) (refining definition of area to be the Hydrographic 
Area 212). EPA concluded that actual attainment and nonattainment 
designations with respect to the new PM-10 NAAQS were not required 
under the Act and retained the TSP designations in place at the time.
    In 1990 Congress amended the Clean Air Act. Under section 
107(d)(4)(B)(i) of the amended Act, all areas identified as Group I 
areas with respect to the PM-10 NAAQS were designated nonattainment by 
operation of law on November 15, 1990--the enactment date of the 1990 
Clean Air Act Amendments. Section 188(a) of the amended Act further 
required that all areas designated nonattainment by operation of law be 
classified as moderate nonattainment areas. Thus, EPA designated Clark 
County a moderate PM-10 nonattainment area. See 56 FR 11101 (March 15, 
1991) (announcing designation of areas) and 56 FR 56694 (November 6, 
1991) (codifying designations). CAA section 189(a)(2) required moderate 
areas designated by operation of law to submit plans by November 15, 
1991. The County submitted its moderate area plan on December 6, 1991.
    In 1993, EPA found, in accordance with CAA section 188(b)(1)(A), 
that the Clark County area could not practicably attain the PM-10 
standard by the applicable moderate area attainment date of December 
31, 1994, and therefore should be reclassified to a serious PM-10 
nonattainment area. 58 FR 3334 (January 8, 1993). EPA concluded that 
implementation of the control measures included in Clark County's 
moderate area plan would not result in emission reductions sufficient 
to attain the 24-hour standard. EPA also found that a substantial 
portion of PM-10 emissions in the area were due to fugitive dust and 
additional controls would be required. Id.
    Reclassification to a serious PM-10 nonattainment area triggered, 
among other requirements, the requirement to implement more stringent 
control measures (i.e., BACM) and the requirement to submit a revised 
plan demonstrating that the area would attain the PM-10 NAAQS by a new 
attainment date of December 31, 2001. See CAA section 189(b). The 
County submitted a serious area PM-10 plan in 1997 to demonstrate 
attainment in accordance with section 189(b). EPA, however, found this 
attainment demonstration, along with previously submitted plans for 
RACM and BACM,\5\ failed to meet the requirements of the CAA and 
therefore proposed to disapprove these submittals. 65 FR 37324 (June 
14, 1998). Prior to EPA taking final action on the proposed 
disapproval, the State of Nevada withdrew the moderate and serious area 
plans for Clark County. See Letter from Allen Biaggi, Administrator, 
Division of Environmental Protection, Nevada Department of 
Conservation, to Felicia Marcus, Regional Administrator,

[[Page 32275]]

EPA Region 9 (December 5, 2000). On January 5, 2001, EPA issued a 
``finding of nonsubmittal'' for failure to submit the required PM-10 
plans. See 66 FR 1046. This finding was made effective December 20, 
2000, and began an 18-month ``clock'' for mandatory application of 
sanctions and a 2-year clock for promulgation of a Federal 
Implementation Plan (FIP) in accordance with CAA section 179. Id. Under 
the sanctions clock, mandatory sanctions (i.e., tighter offset ratios 
for new and modified major sources and, six months later, highway 
funding restrictions) would be imposed unless and until EPA found the 
State had made a ``complete'' submittal of a plan addressing the 
applicable PM-10 requirements for the Las Vegas Valley. See id. at 1047 
(citing 40 CFR 52.31 and CAA section 179). Under the FIP clock, EPA was 
to promulgate a FIP in place of a SIP unless and until EPA approved a 
SIP for the area.\6\ CAA section 110(c)(1).
---------------------------------------------------------------------------

    \5\ See Clark County's February 15, 1995 submittal, ``Addendum 
to the '' ``Moderate Area''' PM-10 State Implementation Plan for the 
Las Vegas Valley'' (The 1995 RACM Addendum) and December 1994 
submittal ``Providing for the Evaluation, Adoption and 
Implementation of Best Available Control Measures and Best Available 
Control Technology to Improve PM-10 Air Quality'' (1994 BACM Plan).
    \6\ While the FIP Clock expired in December 2002, EPA pursued 
review and approval of the SIP submitted in 2001 rather than 
preparation of a FIP. Today's approval removes the obigation to 
prepare a FIP for the area.
---------------------------------------------------------------------------

B. Serious Area Plan for the Las Vegas Area

    Following EPA's proposed disapproval of the 1997 PM-10 Plan, the 
County began revising its fugitive dust control measures. On June 22, 
2000, the County adopted dust controls for open areas and vacant lots 
(Section 90), dust controls for unpaved roads (Section 91), dust 
controls for unpaved parking lots (Section 92), dust controls for paved 
roads and street sweepers (Section 93), and dust controls for 
construction activities (Section 94 and Construction Activities 
Notebook Including Section 94 Handbook).\7\ On November 16, 2000, the 
County revised Section 0 governing regulatory definitions to include a 
number of definitions related to fugitive dust control measures. These 
rules provide the backbone for the Clark County Serious Area Plan, 
which was adopted by the Clark County Board of Commissioners on June 
19, 2001.\8\ The Nevada Division of Environmental Protection submitted 
Sections 90 through 94 and Section 0, along with the June 19, 2001, 
Plan to EPA on July 25, 2001.\9\ On January 11, 2002, we determined the 
conformity budgets in the Plan were adequate (67 FR 1461) and on 
January 22, 2003, we proposed approval of the Plan and the associated 
rules (68 FR 2954). The Technical Support Document associated with our 
proposed approval is available on EPA's Web site.
---------------------------------------------------------------------------

    \7\ These new fugitive dust rules generally supplement the 
existing PM-10 measures previously approved into the SIP in 1981 and 
1982. The two exceptions are: (1) Section 17 (``Permission to 
Disturb Topsoil''), which is being removed from the SIP by this 
action and replaced with the new Sections 90 through 94; and (2) the 
definitions in sections 1.35 (``Fugitive Dust'') and 1.64 (``Off-
road Vehicle''), which are being replaced by the new definitions in 
Sections 0.70 and 0.114, respectively.
    \8\ In 2001, the Clark County Department of Air Quality 
Management (DAQM) was created to handle both the permitting and 
enforcement functions of the Clark County Health District along with 
the planning functions previously managed by the Clark County 
Department of Comprehensive Planning. Because of the shifting 
organization of the local air agencies, we refer generally to the 
``County'' for both the new DAQM and its predecessor agencies.
    \9\ On October 24, 2002, the State submitted revised versions of 
Sections 90 through 93, dated November 20, 2001, to replace the 
November 16, 2000 versions included with the Plan submittal. In 
addition, on November 19, 2002, the State submitted amendments to 
the Plan regarding SIP commitment deadlines and adoption of local 
ordinances.
---------------------------------------------------------------------------

    The Plan supports the County's strategy of focusing controls on 
sources of fugitive dust. The Plan includes a detailed inventory of PM-
10 emissions in the nonattainment area and uses modeling and monitoring 
data to determine the effect these emissions have on ambient 
concentrations and to identify the significant contributors to 
violations in the area. The Plan and PM-10 monitoring data show the 
area met and continues to meet the annual PM-10 standard but was not 
able to meet the 24-hour standard by the statutory deadline of December 
31, 2001. The Plan further demonstrates that the County has adopted 
control measures meeting the CAA requirements for BACM and MSM and that 
implementation of these measures will result in reductions in the 
inventory of emissions to levels that ensure the area will attain the 
24-hour standard by the extended attainment date of December 31, 2006. 
The Plan also includes demonstrations of reasonable further progress 
between now and the 2006 attainment deadline, a demonstration of the 
need for an extension, a description of contingency measures and 
enforceable commitments, and motor vehicle emissions budgets for 
ensuring transportation projects conform to the Plan.
    We received comments on several aspects of the Plan and our 
responses to these comments are provided in a separate document. See 
Response to Comments Document (April 2004). While the comments led us 
to look more carefully at certain demonstrations and, in some cases, 
request additional information from the County, we have not changed our 
conclusions from the proposal that the rules and Plan comply with the 
requirements of the Act and reasonably support the County's 
demonstration of attainment.

IV. Other Related Action in the Las Vegas Area

    In addition to working on this PM-10 Plan and the associated 
fugitive dust rulemakings, the County is in the process of updating air 
control requirements on several other fronts. The County has revised 
its stationary source permitting regulations for new and modified 
sources in Sections 12, 58 and 59 (and portions of Section 0). These 
regulations will ensure that new and modified major sources of PM-10 
and other nonattainment criteria pollutants will be subject to offset 
and control requirements. In addition EPA is in the final stages of 
reviewing the Las Vegas carbon monoxide (CO) attainment plan. EPA 
proposed approval of this plan, which includes inspection and 
maintenance and gasoline and transportation control measure provisions, 
on January 28, 2003 (68 FR 4141). These actions may provide incidental 
PM-10 benefits for the area and will be reviewed to ensure consistency 
with today's action.

V. Final Actions

    With this final action, we are incorporating by reference the 
following portions of the Clark County Serious Area Plan for the Las 
Vegas Planning Area, adopted June 19, 2001, with amendments adopted 
November 19, 2002, into the Nevada SIP:
    (1) The demonstration in Chapter 4 and Appendices G and J that the 
Plan provides for implementation of BACM as required under CAA section 
189(b)(1)(B).
    (2) The baseline and projected emissions inventories provided in 
Chapter 3 and Appendices B through E and L as required under CAA 
section 172(c)(3).
    (3) The demonstration in Chapters 5 and 7 of attainment of the 
annual standard by the CAA deadline of December 31, 2001 and that 
attainment of the 24-hour standard by December 31, 2001 is 
impracticable as required under CAA section 189(b)(1)(A).
    (4) The demonstration in Chapter 7 and Appendix A that attainment 
of the 24-hour standard will occur by the most expeditious alternative 
date practicable, in this case, December 31, 2006, as required under 
CAA sections 189(b)(1)(A) and 188(e).
    (5) The demonstration in Chapter 6 that the Plan includes MSM as 
required under CAA section 188(e).

[[Page 32276]]

    (6) The demonstration in Chapter 4 that major sources of PM-10 
precursors such as nitrogen oxides and sulfur dioxide do not 
significantly contribute to violations of the PM-10 standards as 
required under CAA section 189(e).
    (7) The demonstration in Chapter 5 and Appendix M that the Plan 
provides for reasonable further progress and quantitative milestones as 
required under CAA sections 189(c) and 172(c)(2).
    (8) The contingency measures in Chapter 4 as required under CAA 
section 172(c)(9).
    We are also approving the following transportation conformity motor 
vehicle emissions budgets in Appendix N \10\ as required under CAA 
section 176(c):
---------------------------------------------------------------------------

    \10\ EPA notified Clark County that the motor vehicle emissions 
budgets were adequate by letter from Jack Broadbent, EPA, to Allen 
Biaggi, Nevada Division of Environmental Protection, November 9, 
2001. Public notice of EPA's adequacy determination was provided on 
January 11, 2002 (67 FR 1461).

------------------------------------------------------------------------
                                                      Motor vehicle

2006...........................................                   141.41
------------------------------------------------------------------------

    Finally, today's final approval includes additions to and removals 
from the SIP of specific local measures as follows:
    (1) We are approving into the SIP Clark County Sections 90, 91, 92 
and 93, adopted on November 20, 2001, which supersede earlier versions 
submitted in Appendix G of the Plan.
    (2) We are approving the following portions of Section 0, adopted 
on November 16, 2000, into the SIP: \11\

    \11\ Clark County included all of Section 0 in Appendix G of the 
Plan. In this action, we are approving only definitions relevant to 
Sections 90 through 94.

    (3) We are approving into the SIP the commitments contained in 
Chapter 4, section 4.8.
    (4) We are approving into the SIP Clark County Section 94, adopted 
on November 16, 2000, along with the associated August 24, 2000, 
``Construction Activities Notebook including the Section 94 Handbook'' 
(Appendix G).
    (5) We are removing from the SIP Clark County Section 17 
``Permission to Disturb Topsoil'' and Sections 1.35 (defining 
``Fugitive Dust'') and 1.64 (defining ``Off-road Vehicle'') because 
these sections are replaced by the overlapping provisions in Sections 0 
and 90 through 94 being approved today.

VI. Administrative Requirements

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is not a ``significant regulatory action'' and therefore is not 
subject to review by the Office of Management and Budget. For this 
reason, this action is also not subject to Executive Order 32111, 
``Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action 
merely approves state law as meeting federal requirements and imposes 
no additional requirements beyond those imposed by state law. 
Accordingly, the Administrator certifies that this rule will not have a 
significant economic impact on a substantial number of small entities 
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because 
this rule approves pre-existing requirements under state law and does 
not impose any additional enforceable duty beyond that required by 
state law, it does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Public Law 104-4).
    This rule also does not have tribal implications because it will 
not have a substantial direct effect on one or more Indian tribes, on 
the relationship between the Federal Government and Indian tribes, or 
on the distribution of power and responsibilities between the Federal 
Government and Indian tribes, as specified by Executive Order 13175 (65 
FR 67249, November 9, 2000). This action also does not have Federalism 
implications because it does not have substantial direct effects on the 
States, on the relationship between the national government and the 
States, or on the distribution of power and responsibilities among the 
various levels of government, as specified in Executive Order 13132 (64 
FR 43255, August 10, 1999). This action merely approves a state plan 
and rules implementing a Federal standard, and does not alter the 
relationship or the distribution of power and responsibilities 
established in the Clean Air Act. This rule also is not subject to 
Executive Order 13045 ``Protection of Children from Environmental 
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997), because 
it is not economically significant.
    In reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. In 
this context, in the absence of a prior existing requirement for the 
State to use voluntary consensus standards (VCS), EPA has no authority 
to disapprove a SIP submission for failure to use VCS. It would thus be 
inconsistent with applicable law for EPA, when it reviews a SIP 
submission, to use VCS in place of a SIP submission that otherwise 
satisfies the provisions of the Clean Air Act. Thus, the requirements 
of section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not 
impose an information collection burden under the provisions of the 
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
    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 rule 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 August 9, 2004. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this rule 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).)
