Approval and Promulgation of Implementation Plans; Revisions to 
the Nevada State Implementation Plan; Updated Statutory and Regulatory 
Provisions; Rescissions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: Under the Clean Air Act, EPA is proposing to approve certain 
revisions, and to disapprove certain other revisions, to the Nevada 
State Implementation Plan submitted by the Nevada Division of 
Environmental Protection on January 12, 2006 and June 26, 2007. The 
provisions that are proposed for approval include certain definitions; 
prohibitory rules; provisions related to legal authority and 
enforcement; rules establishing opacity, sulfur and volatile organic 
compound limits; and rescission of abbreviations. The proposed approval 
of a certain statutory provision related to legal authority is 
contingent upon receipt of public process documentation of adoption of 
the provision as a revision to the state implementation plan. The 
proposed disapproval relates to rescission of a certain definition and 
rescission of a rule related to emission discharge information. EPA is 
proposing this action under the Clean Air Act obligation to take action 
on submittals of revisions to state implementation plans. The intended 
effect is to update the Nevada state implementation plan with amended 
or recodified rules and with an amended statutory provision and to 
rescind a provision found to be unnecessary for further retention in 
the plan.

I. The State's Submittal

A. Which SIP revisions did the State submit?

    On February 16, 2005, the Governor's designee, the Nevada Division 
of Environmental Protection (NDEP), submitted a large revision to the 
applicable Nevada State Implementation Plan (SIP) to EPA for approval 
under section 110 of the Clean Air Act (CAA or ``Act''). The February 
16, 2005 SIP submittal includes new and amended statutory provisions 
and rules as well as rescissions of certain statutory provisions and 
rules approved by EPA into the applicable SIP. The statutes, rules and 
rescissions submitted by NDEP on February 16, 2005 relate to 
definitions, administrative requirements, prohibitory rules, and 
permitting-related requirements and procedures. The February 16, 2005 
SIP submittal also contains documentation of public participation 
(i.e., notice and public hearing) and adoption for all rule amendments 
up to and including those adopted by the State Environmental Commission 
on November 30, 2004.
    On January 12, 2006, NDEP re-submitted most of the earlier 
submittal as modified to reflect new or amended rules adopted by the 
State Environmental Commission on October 4, 2005. The January 12, 2006 
SIP revision submittal supersedes the regulatory portion of the earlier 
SIP submittal but is not a complete re-submittal in that it did not 
include the documentation of public notice and

[[Page 71096]]

hearing previously submitted. The January 12, 2006 SIP submittal does 
include such documentation for amendments adopted by the commission on 
October 4, 2005.
    The primary purpose of these SIP submittals is to clarify and 
harmonize the provisions approved by EPA under section 110 of the Act 
with the current provisions adopted by the State. Because these SIP 
submittals incorporate so many changes from 1970s and 1980s vintage SIP 
regulations, EPA has decided to review and act on them in a series of 
separate actions.
    The first such action, related to various definitions, sulfur 
emission rules, and restrictions on open burning and use of 
incinerators was proposed in the Federal Register on September 13, 2005 
(70 FR 53975) and finalized on March 27, 2006 (71 FR 15040). The second 
such action, related to statutory authority, was proposed on June 9, 
2006 (71 FR 33413) and finalized on August 31, 2006 (71 FR 51766). A 
third action, related to most of the State's rescission requests, was 
proposed on August 28, 2006 (71 FR 50875); EPA finalized action on most 
of the rescissions covered by the August 28th proposal on January 3, 
2007 (72 FR 11), finalized rescission of a Federal Implementation Plan 
(FIP) for regulation of fugitive sulfur oxides emissions from a defunct 
copper smelter on June 13, 2007 (72 FR 32529), and finalized action on 
the rest of the rescissions covered by the August 28th proposal on 
November 2, 2007 (72 FR 62119). A fourth action, related to monitoring 
and volatile organic compound (VOC) rules, was proposed on August 31, 
2006 (71 FR 51793) and finalized on December 11, 2006 (71 FR 71486). A 
fifth action, related to excess emissions provisions, was proposed on 
December 18, 2006 (71 FR 75690) but has not yet been finalized. A sixth 
action, related to visible emissions and particulate matter rules, was 
proposed on March 12, 2007 (72 FR 10960) and finalized on May 8, 2007 
(72 FR 25971). A seventh action, related to permitting-related rules, 
was proposed on April 17, 2007 (72 FR 19144) but has not been 
finalized.
    Upon publication of the seventh action cited above, we have at 
least proposed action on all of the new or amended rules submitted by 
NDEP on January 12, 2006, except for Nevada Administrative Code (NAC) 
NAC 445B.227 (``Prohibited conduct: Operation of source without 
required equipment; removal or modification of required equipment: 
modification of required procedure'') and NAC 445B.200 (`` `Violation' 
defined''). We include NAC 445B.227 in today's proposed rule. We will 
take action on NAC 445B.200, which is a permitting-related definition, 
in a separate rulemaking.
    Also, upon publication of the seventh action cited above, we have 
at least proposed action on all of the rescissions submitted by NDEP on 
January 12, 2006 except for rule 25 of general order number 3 of the 
Nevada Public Service Commission, NAC 445.655 (``Abbreviations''), NAC 
445.694 (``Emission discharge information''), and Nevada Revised 
Statutes (NRS) 704.820 to 704.900 (``Construction of utility 
facilities: utility environmental protection act''). We include the 
rescissions of NAC 445.655 (``Abbreviations'') and NAC 445.694 
(``Emission discharge information'') in today's proposed rule. We will 
take action NDEP's rescissions of rule 25 of general order number 3 and 
NRS 704.820 to 704.900, which are permitting-related provisions, in a 
separate rulemaking.
    NDEP has submitted a number of SIP revisions supplementing or 
superseding portions of the January 12, 2006 SIP submittal, but the 
only relevant supplemental SIP revision for the purposes of this 
rulemaking is the one submitted on June 26, 2007. NDEP organized the 
June 26, 2007 SIP submittal into four parts. The first part contains 
public participation documentation for 11 rescissions that we proposed 
to approve in our August 28, 2006 proposed rule. We took final action 
on the 11 rescissions on November 2, 2007 (72 FR 62119). The second 
part contains amended rules and an amended statutory provision that 
would replace corresponding existing provisions in the Nevada SIP. In 
the third part, NDEP requests rescission of existing rule NAC 445.436 
(`` `Air contaminant' defined'') from the SIP. The fourth part contains 
recodifications of rules recently approved by EPA into the SIP. We 
include the second, third, and fourth parts of NDEP's June 26, 2007 SIP 
submittal in this rulemaking.
    Table 1 lists amended rules or statutory provisions intended to 
replace early 1980's versions of these provisions. The provisions 
listed in table 1 include NAC 445B.227, which was submitted on January 
12, 2006, and the seven amended rules and one amended statutory 
provision submitted by NDEP on June 26, 2007.

    Table 2 lists three rules that NDEP seeks to rescind from the 
existing SIP. NDEP's rescission of NAC 445.655 and NAC 445.694 are 
included in the January 12, 2006 SIP submittal, and NDEP's rescission 
of NAC 445.436 is included in the June 26, 2007 SIP submittal.

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

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 section 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 recodified 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 and codifies air quality statutes in chapter 445B (``Air 
Pollution'') of title 40 (``Public Health and Safety'') of the NRS.
---------------------------------------------------------------------------

    \1\ Provisions that EPA promulgates 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 at 
various times between 1975 and 1984. Since 1984, EPA had 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. The difference between the two 
sets of rules is sometimes referred to as the ``SIP gap,'' and closing 
the gap was one of the primary motivations behind NDEP's comprehensive 
SIP update that produced the February 16, 2005 and January 12, 2006 SIP 
submittals followed by supplemental SIP submittals such as the June 26, 
2007 SIP submittal.

C. What is the purpose of this proposed rule?

    The purpose of this proposed rule is to present our evaluation 
under the Clean Air Act and EPA's regulations of certain provisions, 
rescissions, and recodifications contained in NDEP's January 12, 2006 
and June 26, 2007 SIP revision submittals. The provisions submitted for 
approval include updated definitions; updated administrative, 
enforcement, and prohibitory rules; and a statutory provision related 
to legal authority. The rescissions relate to a certain definition, 
abbreviations, and a rule involving emission discharge information. The 
rule recodifications involve minor changes to rule titles and 
historical notes in certain definitions, particulate matter rules, 
sulfur emission rules, and a volatile organic compound rule. We provide 
our reasoning in general terms below but provide a more detailed 
analysis in the technical support document (TSD) that has been prepared 
for this proposed rulemaking.

II. EPA's Evaluation and Action

    We reviewed the provisions, rescissions, and recodifications 
submitted by NDEP that are listed in the three tables above for 
compliance with CAA requirements for SIPs in general as set forth in 
CAA section 110(a)(2) and 40 CFR part 51 and also for compliance with 
requirements for SIP revisions under CAA section 110(l).\2\ Our 
consideration of the rules submitted on January 12, 2006 and June 26, 
2007, and evaluated herein, takes into account the public participation 
documentation contained in the February 16, 2005 and January 12, 2006 
SIP submittals. For the submitted rule recodifications, our review is 
cursory in nature consistent with EPA memorandum, ``Review of State 
Regulation Recodifications,'' from Johnnie L. Pearson, Chief, Regional 
Activities Branch, EPA Office of Air Quality Planning and Standards, 
dated February 12, 1990.
---------------------------------------------------------------------------

    \2\ CAA section 110(l) states: ``Each revision to an 
implementation plan submitted by a State under this chapter shall be 
adopted by such State after reasonable notice and public hearing. 
The Administrator shall not approve a revision of a plan if the 
revision would interfere with any applicable requirement concerning 
attainment and reasonable further progress (as defined in section 
7501 of this title), or any other applicable requirement of this 
chapter.''
---------------------------------------------------------------------------

A. Amended Rules and Statutory Provision

    Based on a review of applicable CAA and EPA regulatory requirements 
and a comparison with the corresponding existing SIP provisions that 
they would replace, we propose to approve all of the

[[Page 71098]]

provisions listed in table 1 above. In general, the submitted 
provisions mirror the corresponding provisions in the existing SIP or 
would strengthen the SIP by eliminating exceptions, deleting 
limitations, or expanding legal authority, and thereby would not 
interfere with attainment or maintenance of the NAAQS.
    With respect to public participation requirements under CAA section 
110(l), we find that adequate documentation has been submitted by NDEP 
(or otherwise acquired by EPA) to show compliance with CAA procedural 
requirements for SIP revisions under CAA section 110(l) except for NRS 
445B.310. Thus, our proposed approval of NRS 445B.310 is contingent 
upon receipt of documentation of notice and opportunity for public 
hearing on adoption of NRS 445B.310 as a revision to the Nevada SIP.\3\
---------------------------------------------------------------------------

    \3\ In so doing, we recognize that we have not consistently 
required the State of Nevada to submit public participation 
documentation for SIP revisions involving statutory provisions and 
should have done so. With Nevada rules, we typically consider the 
public process conducted by the relevant State administrative agency 
(usually the State Environmental Commission) in adopting new or 
amended rules as adequate to comply the procedural requirements for 
SIP revisions under CAA section 110(l). In contrast to rules, 
however, Nevada statutory provisions are typically submitted to EPA 
without an analogous public process, and thus NDEP must conduct a 
public process specifically for the purpose of adopting statutory 
provisions as a revision to the SIP to comply with section 110(l).
---------------------------------------------------------------------------

    Our TSD provides additional background information and a more 
detailed rationale for our proposed approval of the provisions listed 
in table 1 above.

B. Rule Rescissions

    We have reviewed the rescissions listed in table 2 to determine 
whether any of them should be retained to comply with CAA or EPA 
requirements for SIPs, whether rescission of any of them would 
interfere with attainment or maintenance of the NAAQS, or whether any 
of them should be retained as a practical matter because of reliance on 
them by other SIP rules.
    Based on this review, we have found that NAC 445.436 (```Air 
contaminant' defined'') should be retained because it is relied upon by 
certain SIP rules that remain in the applicable SIP. We find that NAC 
445.655 (``Abbreviations'') may be rescinded because the abbreviations 
listed therein that are not simply superseded by our approval of the 
current version of the rule (i.e., NAC 445B.211 (``Abbreviations''), 
approved on March 27, 2006 at 71 FR 15040) are not relied upon by any 
rules in the applicable SIP. Lastly, with respect to NAC 445.694 
(``Emission discharge information''), we find that the rule should be 
retained to comply with requirements under 40 CFR 51.116(c).
    Therefore, we propose to disapprove the rescission requests for NAC 
445.436 and NAC 445.694 and to approve the rescission request for NAC 
445.655. Our TSD provides additional background information and a more 
detailed rationale for our proposed actions on the rescissions listed 
in table 2 above.

C. Rule Recodifications

    We have compared the rule recodifications submitted by NDEP and 
listed in table 3 above with the corresponding SIP rules to ensure that 
the changes are administrative in nature. Based on this comparison, we 
find all of the changes, which include revised titles and updates to 
internal rule references and historical notes, to be administrative in 
nature and acceptable. Therefore, we propose to approve the rule 
recodifications listed in table 3, above. Our TSD provides additional 
background information and discussion for our proposed approval of the 
rule recodifications listed in table 3 above.

III. Public Comment and Proposed Action

    Under section 110(k) of the Clean Air Act and for the reasons set 
forth above, EPA is proposing to approve certain revisions, and to 
disapprove certain other revisions, to the Nevada SIP submitted by NDEP 
on January 12, 2006 and June 26, 2007. The provisions that are proposed 
for approval include certain definitions; prohibitory rules; provisions 
related to legal authority and enforcement; rules establishing opacity, 
sulfur and volatile organic compound limits; and rescission of 
abbreviations. The proposed approval of a certain statutory provision 
related to legal authority is contingent upon receipt of public process 
documentation of adoption of the provision as a revision to the state 
implementation plan. The proposed disapproval relates to rescission of 
a certain definition and rescission of a rule related to emission 
discharge information.
    Unless we receive convincing new information during the comment 
period, we intend to publish a final rule that will approve the new or 
amended rules shown in table 1, above, approve the rescission of 
existing SIP rule NAC 445.655 (``Abbreviations''), approve the rule 
recodifications shown in table 3, above, as revisions to the Nevada 
SIP, but retain existing SIP rules NAC 445.436 (```Air contaminant' 
defined'') and NAC 445.694 (``Emission discharge information'') in the 
SIP. \4\ \5\
---------------------------------------------------------------------------

    \4\ The approval of submitted statutory provision NRS 445B.310 
is contingent upon receipt of public process documentation from NDEP 
adopting this provision as a revision to the Nevada SIP.
    \5\ Final approval of the provisions listed in table 1 of this 
notice would supersede the following provisions in the applicable 
SIP (superseding rules shown in parentheses) upon the established 
compliance date for any new or amended requirements in the 
superseding provisions: NAC 445.617 (NAC 445B.172), NAC 445.630 (NAC 
445B.190), NAC 445.660 (NAC 445B.220), NAC 445.663 (NAC 445B.225), 
NAC 445.664 (NAC 445B.227), NAC 445.665 (NAC 445B.229), NAC.696 (NAC 
445B.275), NAC 445.697 (NAC 445B.277), and NRS 445.493 (NRS 
445B.310). Final approval of the rule recodifications listed in 
table 3 of this notice would supersede rules with the same section 
number in NAC chapter 445B.

IV. Statutory and Executive Order Reviews

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
proposed 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 proposed 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 proposes to approve state law 
as meeting Federal requirements and imposes no additional requirements 
beyond those imposed by state law. Accordingly, the Administrator 
certifies that this proposed 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 proposes to 
approve 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 proposed 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 proposed 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

[[Page 71099]]

levels of government, as specified in Executive Order 13132 (64 FR 
43255, August 10, 1999). This action merely proposes to approve state 
law implementing a Federal standard, and does not alter the 
relationship or the distribution of power and responsibilities 
established in the Clean Air Act. This proposed 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 proposes to approve 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.).
