40 CFR Part 52

[EPA-R09-OAR-2014-0495; FRL-9914-16-Region 9]

Revision of Air Quality Implementation Plan; Nevada; Clark 
County; Stationary Source Permits

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to fully approve permitting related rules 
submitted by Nevada as a revision to the Clark County Department of Air 
Quality (Clark or DEQ) portion of the state implementation plan (SIP) 
for the State of Nevada. These rules were adopted by DEQ to regulate 
the construction and modification of stationary sources of air 
pollution within Clark County. EPA is proposing to approve this SIP 
revision based on the Agency's conclusion that the rules are consistent 
with applicable Clean Air Act (CAA or Act) requirements, policies and 
guidance. Final approval of these rules would make the rules federally 
enforceable and correct program deficiencies identified in a previous 
EPA rulemaking.

DATES: Written comments must be received on or before August 22, 2014.

I. The State's Submittals

A. Which rules did the State submit?

    On April 1, 2014, the Nevada Department of Environmental Protection 
(NDEP), on behalf of Clark County Department of Air Quality (Clark), 
submitted amended regulations and a request to remove several outdated 
regulations, to EPA for approval as revisions to the Clark County 
portion of the Nevada SIP under the CAA. These New Source Review (NSR) 
SIP revision submittals, referred to herein as the ``NSR SIP 
submittal'' or ``submitted NSR rules,'' are intended to satisfy 
previously identified deficiencies to the requirements under both part 
C (prevention of significant deterioration) (PSD) and part D 
(nonattainment new source review) of title I of the Act as well as the 
general preconstruction review requirements for minor sources under 
section 110(a)(2)(C) of the Act. Please see our previous proposed and 
final rulemakings for a more detailed description of these rules and 
the permitting program in Clark County, Nevada. 77 FR 43206 (July 24, 
2012); 77 FR 64039 (October 18, 2012).
    Table 1 lists the rules addressed by this proposal with the dates 
that they were adopted by Clark and submitted to EPA by NDEP, which is 
the governor's designee for Nevada SIP submittals.

    NDEP's SIP submittal includes evidence of public notice and 
adoption of these regulations. On May 5, 2014, Clark's April 1, 2014 
submittal was determined by EPA to meet the completeness criteria in 40 
CFR part 51, appendix V, which must be met before formal EPA review. 
Our technical support document (TSD) provides additional background 
information on each of the submitted rules.

B. What are the existing Clark County rules governing stationary source 
permits in the Nevada SIP?

    The existing SIP-approved NSR program for new or modified 
stationary sources in Clark County consists of one State regulation and 
seven Clark County regulations (``Sections'') which EPA approved on 
September 7, 2004 and October 18, 2012, respectively. See 69 FR 54006 
(final rule approving in whole or in part, Section 11 and Nevada 
Administrative Code (NAC) 445B.22083) and 77 FR 64039 (final rule 
partially approving and partially disapproving Sections 0, 12.0, 12.1, 
12.2, 12.3 and 12.4). Collectively, these regulations establish the NSR 
requirements for both major and minor stationary sources under DAQ 
jurisdiction in Clark County.
    Consistent with Clark's stated intent to have the submitted NSR 
rules replace existing SIP Sections 1 and 11, in their entirety, EPA's 
approval of the regulations identified above in table 1 would have the 
effect of entirely superseding, or rescinding our prior approval of 
Sections 1 and 11. Section 1 contains outdated definitions that have 
been replaced by Section 0 and Section 11 is a rule that defines the 
term ``ambient air quality standards'' and provides definitions for 
terms used in that definition. The term ``National Ambient Air Quality 
Standard'' is now used throughout the Section 12 series of rules and is 
now defined in Section 0. Our proposed action would have no effect on 
NAC 445B.22083 which remains part of the applicable Nevada SIP.

C. What is the purpose of this proposed rule?

    The purpose of this proposed rule is to present our evaluation 
under the CAA and EPA's regulations of the new and amended NSR rules 
submitted by DAQ on April 1, 2014, as identified in table 1. Clark 
amended these rules to correct program deficiencies identified by EPA 
on October 18, 2012 (77 FR 64039). We provide our reasoning in general 
terms below but provide more detailed analysis in our TSD, which is 
available in the docket for this proposed rulemaking.

II. EPA's Evaluation

A. How is EPA evaluating the rules?

    EPA has reviewed the rules submitted by Clark governing NSR for 
stationary sources under DAQ jurisdiction for compliance with the CAA's 
general requirements for SIPs in CAA section 110(a)(2), EPA's 
regulations for stationary source permitting programs in 40 CFR part 
51, sections 51.160 through 51.166, and the CAA requirements for SIP 
revisions in CAA section 110(l).\2\ As described below, EPA is 
proposing approval of the submitted NSR rules.
---------------------------------------------------------------------------

    \2\ CAA section 110(l) requires SIP revisions to be subject to 
reasonable notice and public hearing prior to adoption and submittal 
by States to EPA and prohibits EPA from approving any SIP revision 
that would interfere with any applicable requirement concerning 
attainment and reasonable further progress, or any other applicable 
requirement of the CAA.
---------------------------------------------------------------------------

B. Do the rules meet the evaluation criteria?

    With respect to procedures, CAA sections 110(a) and 110(l) require 
that revisions to a SIP be adopted by the State after reasonable notice 
and public hearing. EPA has promulgated specific procedural 
requirements for SIP revisions in 40 CFR part 51, subpart F. These 
requirements include publication of notices, by prominent advertisement 
in the relevant geographic area, of a public hearing on the proposed 
revisions, a public comment period of at least 30 days, and an 
opportunity for a public hearing.
    Based on our review of the public process documentation included in 
the April 1, 2014 submittal, we find that Clark has provided sufficient 
evidence of public notice and opportunity for comment and public 
hearings prior to adoption and submittal of these rules to EPA.
    With respect to substantive requirements, we have evaluated each 
``Section'' of the submitted NSR rules in

[[Page 42754]]

accordance with the CAA and regulatory requirements that apply to: (1) 
General preconstruction review programs for minor sources under section 
110(a)(2)(C) of the Act, (2) PSD permit programs under part C of title 
I of the Act, and (3) Nonattainment NSR permit programs under part D of 
title I of the Act. We are proposing to find that the submitted NSR 
rules satisfy the applicable requirements for these three permit 
programs and would strengthen the applicable SIP by correcting and 
updating the regulations. Final approval of these NSR rules would 
correct all deficiencies in Clark's permit programs identified in our 
October 18, 2012 final rule. See 77 FR 64039.
    In addition, EPA notes that in 2012 it partially disapproved 
Nevada's infrastructure SIP (I-SIP) submittals for the 1997 ozone, 1997 
PM2.5, and 2006 PM2.5 NAAQS for several elements 
under section 110(a)(2) of the Clean Air Act. This included a partial 
disapproval for section 110(a)(2)(F)(iii), which requires the 
correlation of emissions reports and data collected under section 
110(a)(2)(F)(ii) with any applicable emission limits or standards, and 
that such reports be made available for public inspection. See 77 FR 
64737 (October 23, 2012). EPA finalized a similar disapproval with 
respect to Nevada's I-SIP submittal for the 2008 Pb NAAQS in 2014. See 
79 FR 15697 (March 21, 2014). If finalized, today's action on Clark 
County rule Section 12.0 would cure the partial disapproval from EPA's 
2012 and 2014 I-SIP actions and turn off the two-year FIP clock for CAA 
section 110(a)(2)(F)(iii), which expires on November 23, 2014. Id. The 
TSD for this action contains a more detailed discussion of our 
evaluation.
    Section 110(l) prohibits EPA from approving a revision of a plan if 
the revision would ``interfere with any applicable requirement 
concerning attainment and reasonable further progress . . . or any 
other applicable requirement of [the Act].''
    We find that the SIP revision represents a strengthening of Clark 
County's minor NSR, PSD, and Nonattainment NSR programs compared to the 
existing SIP programs that we approved in 2012, and that our approval 
of the NSR SIP submittal would not interfere with any applicable 
requirement concerning attainment and reasonable further progress (RFP) 
or any other applicable requirement of the Act.
    For the reasons stated above and explained further in our TSD, we 
find that the submitted NSR rules satisfy the applicable CAA and 
regulatory requirements for minor NSR, PSD, and Nonattainment NSR 
permit programs under CAA section 110(a)(2)(C) and parts C and D of 
title I of the Act. Therefore, we are proposing a full approval of the 
submitted NSR rules listed in table 1 and rescission of the rules 
listed in table 2.

III. Public Comment and Proposed Action

    Pursuant to section 110(k) of the CAA and for the reasons provided 
above and described more fully in the TSD for this rulemaking, EPA is 
proposing to fully approve the amended Clark County regulations listed 
in table 1, above, as a revision to the Clark County portion of the 
Nevada SIP. In addition EPA is proposing to rescind from the SIP the 
Clark County regulations listed in table 2, above. If finalized as 
proposed, the submitted rules will supersede the existing SIP rules 
that provide for permitting of new or modified stationary sources in 
Clark County, including all of existing SIP sections 1, 11 and 24.
    We will accept comments from the public on this proposal for the 
next 30 days.

IV. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Act and 
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, EPA's role is to approve State 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this action merely proposes to approve State law as 
meeting Federal requirements and does not impose additional 
requirements beyond those imposed by State law. For that reason, this 
proposed 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.);
     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 proposed rule 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.
