I. Proposed Action

    On January 28, 2003 (68 FR 4141), with the exception of two 
individual contingency measures that we proposed to disapprove, we 
proposed to approve the following state implementation plan (SIP) 
revisions submitted by the State of Nevada to provide for attainment of 
the carbon monoxide (CO) national ambient air quality standards (NAAQS) 
under the Clean Air Act, as amended in 1990 (CAA or ``Act''), in the 
``serious'' Clark County CO nonattainment area, which is defined as 
State hydrographic area 212 and referred to as the ``Las Vegas 
Valley'':
    (1) State of Nevada State Implementation Plan for an Enhanced 
Program for the Inspection and Maintenance of Motor Vehicles for Las 
Vegas Valley and Boulder City (March 1996) submitted by the Nevada 
Division of Environmental Protection (NDEP) on March 20, 1996;
    (2) Carbon Monoxide State Implementation Plan, Las Vegas Valley 
Nonattainment Area, Clark County, Nevada (August 2000) (``2000 CO 
plan'') adopted by the Clark County Board of Commissioners on August 1, 
2000, and submitted by NDEP on August 9, 2000, which addresses 
requirements under the Act for notice and adoption, baseline and 
projected emissions inventories, the reasonable further progress (RFP) 
demonstration, the attainment demonstration, vehicle miles traveled 
(VMT) forecasts, and which also includes updated vehicle inspection and 
maintenance (I/M) program materials, Clark County's Cleaner Burning 
Gasoline (CBG) program, an alternative fuel program for government 
vehicles, voluntary transportation control measures (TCMs), a 
determination that stationary sources do not contribute significantly 
to CO levels, contingency measures\1\, commitments for further 
submittals and control measures, as needed, and CO emissions budgets 
for transportation conformity purposes;
---------------------------------------------------------------------------

    \1\ In this notice, we are not taking final action on the 
contingency provisions (i.e., contingency measures and related 
commitments in the 2000 CO plan) in part because we have not yet 
received the quantitative analysis (using MOBILE6) of CO emissions 
reductions associated with implementation of standardized On-Board 
Diagnostics systems (OBD II) testing, which was the one contingency 
measure that we had proposed to approve. We had anticipated 
submittal of this information by early 2003. See the related 
discussion in our proposed rule at 68 FR 4155, column 2. Our 
decision not to proceed with final action on the contingency 
provisions in this notice has no immediate practical effect because 
we are taking final action herein to approve OBD II testing into the 
SIP, not as a contingency measure, but rather as a part of the 
vehicle I/M program. In other words, we are finalizing our approval 
of the vehicle I/M program, which includes OBD II testing, but are 
not finalizing our determination from the proposal that OBD II 
testing, while serving as a required element of the vehicle I/M 
program, also provides for compliance with the contingency provision 
requirements under section 187(a)(3) of the Act. We will be 
addressing the contingency provision requirements for Las Vegas 
Valley under section 187(a)(3) in a separate rulemaking. Please see 
our response to NEC comment 37 in our Response to Comments 
document for our rationale and authority for taking final action on 
the RFP and attainment demonstrations in the 2000 CO plan while 
deferring action on the contingency measures.
---------------------------------------------------------------------------

    (3) Supplemental CO SIP materials submitted by NDEP on January 30, 
2002, including updated State regulations implementing the vehicle I/M 
program, other updated I/M program materials, and a draft regulation 
establishing procedures for on-board diagnostics systems testing of 
newer vehicles; and
    (4) Supplemental CO SIP materials submitted by NDEP on June 4, 
2002, including updated State statutes governing the I/M program, other 
updated vehicle I/M program materials, and the State regulation 
implementing the Reid Vapor Pressure (RVP) specification for wintertime 
gasoline sold in Clark County.
    The proposal contains detailed information on the four SIP 
submittals listed above and our evaluation of the submittals against 
applicable CAA provisions and EPA regulations and policies relating to 
serious area CO SIPs.
    In the proposed rule, we indicated that we were proposing approval 
of certain portions of the SIP submittals based on draft rules and that 
our final approval would not occur until we had received final adopted 
rules from the State. As discussed in the following paragraphs, the 
State has submitted the final adopted rules called for in the proposed 
rule, and in this action, we are

[[Page 56352]]

approving them as revisions to the Nevada SIP.
    By letters dated September 9 and 24, 2003, NDEP submitted SIP 
revisions that included Regulation R178-01 adopted by the Nevada 
Department of Motor Vehicles (DMV) on July 11, 2002 establishing the 
standardized On-Board Diagnostics systems (also known as ``OBD II'') 
test procedures for Nevada's vehicle I/M program and related public 
notice and hearing materials. The regulatory changes to the Nevada 
Administrative Code under adopted regulation R178-01 were made 
effective as of August 21, 2002. (The September 24th SIP submittal 
included a replacement version of Regulation R178-01 because the 
September 9th version of that adopted regulation was missing pages that 
inadvertently had been omitted from the earlier submittal.) In the 
proposed rule, we indicated that we would not take final action on the 
vehicle I/M program until we received the final adopted version of 
regulations establishing test procedures and equipment used for 
inspecting certified on-board diagnostics systems. See 68 FR 4141, at 
4150, column 1 (January 28, 2003). These two SIP submittals contain the 
necessary final adopted regulations and supporting materials and 
thereby provide us with the basis to finalize our proposed approval of 
the vehicle I/M program for Las Vegas Valley and Boulder City. The 
final adopted regulation is consistent with the draft regulation that 
provided the basis for our proposed approval of the vehicle I/M program 
for Las Vegas Valley and Boulder City.
    The September 9th SIP submittal also contains State statutes 
providing for the ``alternate low'' enhanced vehicle I/M program in Las 
Vegas Valley and Boulder City. These statutes represent an update to 
the corresponding statutes that were included as part of the SIP 
submittal dated March 20, 1996 (listed above), and referred to in the 
proposed rule as the ``1996 vehicle I/M submittal.'' See 68 FR 4141, at 
4143, column 1 (January 28, 2003). The updated statutes largely reflect 
administrative changes in the statutes and are equivalent in all 
significant respects to those submitted to EPA in 1996 and listed in 
the proposed rule.
    Lastly, by letter dated November 10, 2003, NDEP submitted a SIP 
revision including the following updated Clark County fuel regulations: 
section 53 (oxygenated gasoline program) and section 54 (cleaner 
burning gasoline (CBG): Wintertime program), which had been adopted by 
the Clark County Board of County Commissioners on May 20, 2003, and 
made effective June 3, 2003. The revisions to sections 53 and 54 are 
administrative in nature and reflect the transfer of air pollution 
control authority in Clark County to the Clark County Board of County 
Commissioners. This completes a sequence of transfers of authority that 
began in mid-2001 with the transfer of air pollution control authority 
in Clark County from the Clark County District Board of Health, which 
originally adopted these rules and which oversaw the Air Quality 
Division of the Clark County Health District, to the Clark County Board 
of County Commissioners sitting as the short-lived ``Clark County Air 
Quality Management Board,'' and then more recently to the Clark County 
Board of County Commissioners.
    The Clark County Board of County Commissioners oversees the 
Department of Air Quality Management (DAQM), which took over the 
responsibilities of the former Air Quality Division of the Clark County 
Health District as well as the air quality planning responsibilities of 
the Clark County Department of Comprehensive Planning. We had made 
submittal of the updated section 54 a condition on our final approval 
of that rule. See 68 FR 4141, at 4152, column 3 (January 28, 2003). The 
State's November 10th submittal satisfies this condition allowing us to 
take final action on the rule.
    In 1999, we approved section 53 as a revision to the Nevada SIP. 
See 64 FR 29573 (June 2, 1999). Like section 54, the amended version of 
section 53 submitted to EPA as part of the November 10th SIP submittal 
simply reflects the change in the applicable administrative agency for 
air pollution control purposes in Clark County.
    We are taking final action on the September 9 and 24, 2003 and 
November 10, 2003 SIP submittals in this final rule without additional 
notice and comment because the updated I/M-related statutes and fuel 
regulations differ in only minor respects from those statutes that were 
previously listed in the proposal, or in the case of section 53, the 
updated regulation reflects only administrative changes. In addition, 
the proposal adequately described and evaluated the provisions 
requiring on-board diagnostics systems checks based on submitted draft 
regulations under EPA's ``parallel processing'' procedure, (see 68 FR 
4141, at 4143, column 3 (January 28, 2003)), and the approval of the 
CBG rule was conditioned upon submittal of the updated rule (see 68 FR 
4141, at 4151, column 2 (January 28, 2003)).

II. Public Comments

    EPA's proposed action provided for a 30-day public comment period. 
During this period, we received comments from the following parties:
    (1) Peter Krueger, Nevada Emission Testers Council, letter dated 
February 19, 2003, providing comments related to possible Legislative 
action to reduce the frequency of testing under the vehicle I/M 
program;
    (2) Edward C. Barry, Chemical Lime Company, letter dated February 
24, 2003, providing comments related to the CO emissions estimate in 
the 2000 CO plan for its facility;
    (3) Fredrick R. Slater, Kerr-McGee Chemical, LLC, letter dated 
February 26, 2003, providing comments related to an alternative 
approach (i.e., to finalizing the action as proposed) involving 
redesignation and working with the County to develop a maintenance 
plan; and
    (4) Robert W. Hall, Nevada Environmental Coalition, Inc., letter 
dated February 27, 2003, providing comments related to virtually all 
aspects of the CO SIP revision submittals and EPA's related proposed 
approval, including statutory and regulatory authority, CO emissions 
inventory and projections, ambient CO monitoring network, notice and 
public hearing, use of EPA guidance in evaluating SIP submittals, the 
vehicle I/M program, EPA's parallel processing procedure, evaluation of 
non-fuel measure alternatives, the attainment demonstration, the status 
of the (stationary source) new source review program, the forecasts of 
vehicle miles traveled (VMT), contingency measures, transportation 
conformity, and EPA enforcement of SIP rules.
    Responses to all comments can be found in our Response to Comments 
Document that accompanies this final action. A copy of the Response to 
Comments Document can be downloaded from our website or obtained by 
calling or writing the contact person listed above. The comments led us 
to look more carefully at certain aspects of the plan and certain 
aspects of our proposed approval; however, with the exception of the 
contingency provisions (for which we are not taking final action in 
this notice), we have not changed our conclusions that the various SIP 
revisions submitted for the Las Vegas Valley CO nonattainment area 
comply with CAA CO nonattainment planning requirements.

III. EPA Action

    Pursuant to section 110(k)(3) of the Act, we are finalizing the 
following

[[Page 56353]]

actions on the various SIP submittals for the Las Vegas Valley 
``serious'' CO nonattainment area in Clark County, Nevada. For each 
action, we indicate the page or pages on which the element is discussed 
in our proposal.
    (1) Approval of procedural requirements, under section 110(a)(1) of 
the Act--see 68 FR 4144;
    (2) Approval of baseline and projected emission inventories, under 
sections 172(c)(3) and 187(a)(1) of the Act and approval of reasonable 
further progress, under sections 172(c)(2) and 187(a)(7) of the Act--
see 68 FR 4144-4146;
    (3) Approval of attainment demonstration, under section 187(a)(7) 
of the Act--68 FR 4146-4147;
    (4) Approval of the ``alternate low'' vehicle I/M program for Las 
Vegas Valley and Boulder City under section 187(a)(6) of the Act--see 
68 FR 4147-4150. Specifically, we approve the statutory and regulatory 
basis for the program set forth in Nevada Revised Statutes (NRS), title 
40, section 445B.210 and sections 445B.700-445B.845, and title 43, 
sections 481.019-481.087, 482.155-482.290, 482.385, 482.461, 482.565, 
and 484.644-484.6441, as amended by the State of Nevada through the 
2001 Legislative sessions, and Nevada Administrative Code (NAC), 
chapter 445B, sections 445B.400-445B.735 (excluding sections 445B.576, 
445B.577, and 445B.578, which are associated with restrictions on 
visible emissions and on idling of diesel vehicles not required by EPA 
I/M program requirements), as amended through March 8, 2002 by the 
Nevada State Environmental Commission and the Nevada Department of 
Motor Vehicles, and also Regulation R178-01 as adopted by the Nevada 
Department of Motor Vehicles on July 11, 2002 (made effective August 
21, 2002) establishing on-board diagnostics systems testing procedures 
for Nevada's vehicle I/M program. Upon the effective date of this final 
rule, the amended Nevada vehicle I/M program described in this notice 
will supercede the existing vehicle I/M program approved by EPA in 1981 
and 1984 as it relates to Las Vegas Valley and Boulder City;
    (5) Approval of the State's low RVP wintertime requirement for 
gasoline sold in Clark County--see 68 FR 4150-4151. Specifically, we 
propose to approve Nevada Administrative Code section 590.065 as 
adopted on October 28, 1998 by the State Board of Agriculture;
    (6) Approval of Clark County air quality regulation section 54 
(Cleaner Burning Gasoline (CBG): Wintertime Program) under section 
211(c)(4)(C) of the Act, as adopted by the Clark County Board of County 
Commissioners on May 20, 2003 (effective June 3, 2003)--see 68 FR 4151-
4152;
    (7) Approval of RTC's CAT MATCH commuter incentive program under 
section 187(b)(2) of the Act and our voluntary mobile source emissions 
reduction program policy--see 68 FR 4152-4153. Specifically, we approve 
the CAT MATCH guidelines as set forth in the Clark County Regional 
Transportation Commission's Resolution No. 177, adopted on June 10, 
1999, and the commitments to implement and monitor the program, to 
prepare annual reports and to remedy, in a timely manner, any shortfall 
of emissions reductions, as set forth in the Clark County Regional 
Transportation Commission's Resolution No. 186, adopted on June 8, 
2000;
    (8) Approval of the Alternative Fuels Program for government 
vehicles in Clark County--see 68 FR 4153. Specifically, we approve the 
regulations set forth in Nevada Administrative Code chapter 486A, as 
amended through April 20, 2000 by the State Environmental Commission;
    (9) Approval of a determination that stationary sources do not 
contribute significantly to ambient CO levels in the Las Vegas CO 
nonattainment area for the purposes of section 187(c) of the Act--see 
68 FR 4153-4154;
    (10) Approval of VMT forecasts and the responsible agencies' 
commitments to revise and replace the VMT projections as needed and 
monitor actual VMT levels in the future, under section 187(a)(2)(A) of 
the Act--see 68 FR 4154. Specifically, we approve the Clark County 
Regional Transportation Commission's commitments to prepare VMT 
estimates, forecasts, and annual VMT tracking reports as set forth in 
Resolution No. 149, as adopted on July 13, 1995;
    (11) Approval of the CO motor vehicle emissions budgets for 2000 
(310.2 tons per day), 2010 (329.5 tons per day), and 2020 (457.4 tons 
per day) as meeting the purposes of section 176(c)(1) and the 
transportation conformity rule at 40 CFR 93, subpart A--see 68 FR 4155-
4156; and
    (12) Approval of amended Clark County SIP rule (section 53--
Oxygenated Gasoline Program), adopted by the Clark County Board of 
County Commissioners on May 20, 2003 (effective June 3, 2003) making 
administrative changes to substitute the Clark County Board of County 
Commissioners and Department of Air Quality Management for its 
corresponding predecessors, the Clark County Board of Health and the 
Air Quality Division of the Clark County Health District. NDEP 
submitted this revised SIP rule with a similarly-revised version of 
Clark County air quality regulation section 54 to EPA as a SIP revision 
on November 10, 2003. Section 553 of the Administrative Procedure Act, 
5 U.S.C. 553(b)(B), provides that, when an agency for good cause finds 
that notice and public procedures are impracticable, unnecessary, or 
contrary to the public interest, the agency may issue a rule without 
providing notice and an opportunity for public comment. We have 
determined that there is such good cause for making our approval of 
amended Clark County air quality regulation section 53 (Oxygenated 
Gasoline Program), as adopted on May 20, 2003, final without prior 
proposal and opportunity for comment because the amended rule merely 
substitutes the current local administrative agency for its 
predecessor. Thus, notice and public procedure are unnecessary. Upon 
the effective date of this final rule, the amended section 53 will 
supercede the existing SIP section 53, approved by EPA on June 2, 1999 
(see 64 FR 29573), in the Nevada SIP.

IV. Statutory and Executive Order Reviews

    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 13211, 
``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 (Pub. L. 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,

[[Page 56354]]

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 rule 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. section 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. 
section 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 November 22, 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).)
