I. The State's Submittal

A. What Regulations Did the State Submit?

    The Governor's designee, the Nevada Department of Conservation and 
Natural Resources, Division of Environmental Protection (NDEP), 
submitted a revision to the applicable state implementation plan (SIP) 
on December 8, 2006.
    Most of the provisions submitted on December 8, 2006 concern 
permitting regulations which are the subject of a separate Federal 
Register proposed rule. The remaining regulations are being acted on in 
this rulemaking and concern clarifications made to harmonize State and 
Federally-enforceable requirements.
    The following table lists the provisions of the Nevada 
Administrative Code (NAC) addressed by this rulemaking with the dates 
they were submitted by NDEP.

                         September 11,
                         1974.
------------------------------------------------------------------------

    The Nevada SIP includes previous versions of these regulations. We 
approved NAC 445B.134, 445B.258, 445B.259, and 445B.260 on December 11, 
2006 (71 FR 71486) and approved NAC 445B.230 on March 27, 2006 (71 FR 
15040). The amended regulations submitted by NDEP on December 8, 2006 
were included as sections 2, 5, 6, 7, and 8 of Regulation R151-06, 
which was adopted by the State Environmental Commission on September 6, 
2006.

B. What Is the Regulatory History of the Nevada SIP?

    Pursuant to the Clean Air Amendments of 1970, the Governor of 
Nevada submitted the original Nevada SIP to EPA in January 1972. EPA 
approved certain portions of the original SIP and disapproved other 
portions under CAA section 110(a). See 37 FR 10842 (May 31, 1972). For 
some of the disapproved portions of the original SIP, EPA promulgated 
substitute provisions under CAA Sec.  110(c).\1\ This original SIP 
included various rules, codified as articles within the Nevada Air 
Quality Regulations (NAQR), and various statutory provisions codified 
in chapter 445 of the Nevada Revised Statutes (NRS). In the early 
1980's, Nevada reorganized and re-codified its air quality rules into 
sections within chapter 445 of the Nevada Administrative Code (NAC). 
Today, Nevada codifies its air quality regulations in chapter 445B of 
the NAC.
---------------------------------------------------------------------------

    \1\ Provisions that EPA promulgated under CAA section 110(c) in 
substitution of disapproved State provisions are referred to as 
Federal Implementation Plans (FIPs).
---------------------------------------------------------------------------

    Nevada adopted and submitted many revisions to the original set of 
regulations and statutes in the SIP, some of which EPA approved on 
February 6, 1975 at 40 FR 5508; on March 26, 1975 at 40 FR 13306; on 
January 9, 1978 at 43 FR 1341; on January 24, 1978 at 43 FR 3278; on 
August 21, 1978 at 43 FR 36932; on July 10, 1980 at 45 FR 46384; on 
April 14, 1981 at 46 FR 21758; on August 27, 1981 at 46 FR 43141; on 
March 8, 1982 at 47 FR 9833; on April 13, 1982 at 47 FR 15790; on June 
18, 1982 at 47 FR 26386; on June 23, 1982 at 47 FR 27070; on March 27, 
1984 at 49 FR 11626. Between 1984 and 2005, EPA approved very few 
revisions to Nevada's applicable SIP despite numerous changes that have 
been adopted by the State Environmental Commission. As a result, the 
version of the rules enforceable by NDEP was often quite different from 
the SIP version enforceable by EPA.
    Recently, Nevada submitted revisions to their SIP on February 16, 
2005, January 12, 2006, and March 24, 2006. EPA approved various 
portions of these submittals on March 27, 2006 at 71 FR 15040; on 
August 31, 2006 at 71 FR 51766; on December 11, 2006 at 71 FR 71486; 
and on January 3, 2007 at 72 FR 11.

C. What Is the Purpose of this Rulemaking?

    The purpose of this rulemaking is to bring the applicable SIP up to 
date. The regulations that are the subject of this rulemaking include a 
definition, a general rule for emergency episodes, and various 
monitoring regulations.

[[Page 19803]]

II. EPA's Evaluation and Action

A. How Is EPA Evaluating the Regulations?

    Generally, SIP regulations must be enforceable (see section 110(a) 
of the Act) and must not relax existing requirements (see sections 
110(l) and 193). Relevant EPA guidance and policy documents that we 
used to help evaluate enforceability include ``Review of State 
Implementation Plans and Revisions for Enforceability and Legal 
Sufficiency,'' dated September 23, 1987, from J. Craig Potter, 
Assistant Administrator for Air and Radiation, et al.

B. Do the Regulations Meet the Evaluation Criteria?

    We believe the following provisions are consistent with the 
relevant policy and guidance regarding enforceability and SIP 
relaxations: NAC 445B.134, NAC 445B.230, NAC 445B.258, NAC 445B.259, 
and NAC 445B.260. Generally, these provisions have been revised by the 
addition of certain clarifications and enhancements. The Technical 
Support Document (TSD) dated March 5, 2007 has more information on our 
evaluation.

C. Public Comment and Final Action.

    As authorized in section 110(k)(3) of the Act, EPA is fully 
approving the submitted rules because we believe they fulfill all 
relevant requirements. We do not think anyone will object to this 
approval, so we are finalizing it without proposing it in advance. 
However, in the Proposed Rules section of this Federal Register, we are 
simultaneously proposing approval of the same submitted rules. If we 
receive adverse comments by May 21, 2007, we will publish a timely 
withdrawal in the Federal Register to notify the public that the direct 
final approval will not take effect and we will address the comments in 
a subsequent final action based on the proposal. If we do not receive 
timely adverse comments, the direct final approval will be effective 
without further notice on June 19, 2007. This will incorporate these 
rules into the federally enforceable SIP.
    Please note that if EPA receives adverse comment on an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, EPA may adopt as final those provisions 
of the rule that are not the subject of an adverse comment.

III. 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, 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 approves a state rule 
implementing a Federal standard.
    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 June 19, 2007. 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).)
