Partial Approval and Disapproval of Air Quality State 
Implementation Plans; Nevada; Infrastructure Requirements for Lead (Pb)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to partially approve and partially disapprove 
State Implementation Plan (SIP) revisions submitted by the State of 
Nevada on October 12, 2011, July 23, 2012, and August 30, 2012, 
pursuant to the requirements of the Clean Air Act (CAA or the Act) for 
the implementation, maintenance, and enforcement of the 2008 Lead (Pb) 
national ambient air quality standards (NAAQS). We refer to such SIP 
revisions as ``infrastructure'' SIPs because they are intended to 
address basic structural SIP requirements for new or revised NAAQS 
including, but not limited to, legal authority, regulatory structure, 
resources, permit programs, monitoring, and modeling necessary to 
assure attainment and maintenance of the standards. We are taking 
comments on

I. Background

A. Statutory Framework and Scope of Infrastructure SIPs

    Section 110(a)(1) of the CAA requires each state to submit to EPA, 
within three years after the promulgation of a primary or secondary 
NAAQS or any revision thereof, a SIP that provides for the 
``implementation, maintenance, and enforcement'' of such NAAQS. Many of 
the section 110(a)(2) SIP elements relate to the general information 
and authorities that constitute the ``infrastructure'' of a state's air 
quality management program and SIP submittals that address these 
requirements are referred to as ``infrastructure SIPs.'' These 
infrastructure SIP elements are as follows:
     Section 110(a)(2)(A): Emission limits and other control 
measures.
     Section 110(a)(2)(B): Ambient air quality monitoring/data 
system.
     Section 110(a)(2)(C): Program for enforcement of control 
measures and regulation of new and modified stationary sources.
     Section 110(a)(2)(D)(i): Interstate pollution transport.
     Section 110(a)(2)(D)(ii): Interstate and international 
pollution abatement.
     Section 110(a)(2)(E): Adequate resources and authority, 
conflict of interest, and oversight of local and regional government 
agencies.
     Section 110(a)(2)(F): Stationary source monitoring and 
reporting.
     Section 110(a)(2)(G): Emergency episodes.
     Section 110(a)(2)(H): SIP revisions.
     Section 110(a)(2)(J): Consultation with government 
officials, public notification, and prevention of significant 
deterioration (PSD) and visibility protection.
     Section 110(a)(2)(K): Air quality modeling and submission 
of modeling data.
     Section 110(a)(2)(L): Permitting fees.
     Section 110(a)(2)(M): Consultation/participation by 
affected local entities.
    Two elements identified in section 110(a)(2) are not governed by 
the three-year submission deadline of section 110(a)(1) and are 
therefore not addressed in this action. These elements relate to part D 
of title I of the CAA, and submissions to satisfy them are not due 
within three years after promulgation of a new or revised NAAQS, but 
rather are due at the same time nonattainment area plan requirements 
are due under section 172. The two elements are: (i) section 
110(a)(2)(C) to the extent it refers to permit programs required under 
part D [nonattainment new source review (NSR)], and (ii) section 
110(a)(2)(I), pertaining to the nonattainment planning requirements of 
part D. As a result, this action does not address infrastructure 
elements related to the nonattainment NSR portion of section 
110(a)(2)(C) or related to 110(a)(2)(I).
    In addition, this rulemaking does not address three substantive 
issues that are not integral to acting on a state's infrastructure SIP 
submission: (i) Existing provisions related to excess emissions during 
periods of start-up, shutdown, or malfunction (SSM) at sources, that 
may be contrary to the CAA and EPA's policies addressing such excess 
emissions; (ii) existing provisions related to ``director's variance'' 
or ``director's discretion'' that purport to permit revisions to SIP 
approved emissions limits with limited public process or without 
requiring further approval by EPA, that may be contrary to the CAA 
(``director's discretion''); and, (iii) existing provisions for PSD 
programs that may be inconsistent with current requirements of EPA's 
``Final NSR Improvement Rule.'' \1\

    \1\ 67 FR 80186 (December 31, 2002), as amended by 72 FR 32526 
(June 13, 2007) (NSR Reform).
---------------------------------------------------------------------------

    Instead, EPA has indicated that it has other authority to address 
any such existing SIP defects in other rulemakings, as appropriate. A 
detailed rationale for why these issues are not part of the scope of 
infrastructure SIP rulemakings can be found in EPA's August 3, 2012 
proposed rule entitled ``Partial Approval and Disapproval of Air 
Quality Implementation Plans; Nevada; Infrastructure Requirements for 
Ozone and Fine Particulate Matter'' in section I.C. (``Scope of the 
Infrastructure SIP Evaluation'').\2\

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

B. Regulatory Background

    On October 15, 2008, EPA issued a revised NAAQS for Pb.\3\ This 
action

[[Page 64432]]

triggered a requirement for states to submit an infrastructure SIP to 
address the applicable requirements of section 110(a)(2) by October 15, 
2011. EPA issued guidance in 2011 for such infrastructure SIPs entitled 
``Guidance on Section 110 Infrastructure SIPs for the 2008 Pb NAAQS'' 
(``EPA's 2011 Pb Guidance'').\4\
---------------------------------------------------------------------------

    \3\ 73 FR 66964. The final rule was signed on October 15, 2008 
and published in the Federal Register on November 12, 2008. The 1978 
Pb standard (1.5 [micro]g/m3 as a quarterly average) was modified to 
a rolling 3-month average not to exceed 0.15 [mu]g/m3. EPA also 
revised the secondary NAAQS to 0.15 [mu]g/m3 and made it identical 
to the revised primary standard.
    \4\ See Memorandum from Stephen D. Page, Director, Office of Air 
Quality Planning and Standards, to Regional Air Division Directors, 
Regions 1-10 (October 14, 2011).
---------------------------------------------------------------------------

II. The State's Submittals

    The Nevada Division of Environmental Protection (NDEP) submitted 
``Nevada's Clean Air Act Sec.  110(a)(1) and (2) State Implementation 
Plan for the 2008 Pb NAAQS'' on October 12, 2011,\5\ which included the 
NDEP and Washoe County Air Quality Management Division (AQMD) portions 
of the state's Pb infrastructure SIP submittal; and submitted the 
``Clark County Lead Infrastructure State Implementation Plan'' on July 
23, 2012,\6\ which is the Clark County Department of Air Quality (DAQ) 
portion of the state's Pb infrastructure SIP submittal. On August 30, 
2012, NDEP submitted the ``Revisions to Nevada's Clean Air Act Sec.  
110(a)(2) State Implementation Plan Submittals,'' \7\ which amended 
several of the state's infrastructure SIP submittals, including the 
October 12, 2011 submittal for the 2008 Pb NAAQS.
---------------------------------------------------------------------------

    \5\ See letter dated October 12, 2011 from Colleen Cripps, 
Administrator, NDEP, to Jared Blumenfeld, Regional Administrator, 
EPA Region 9.
    \6\ See letter dated July 23, 2012 from Colleen Cripps, 
Administrator, NDEP, to Jared Blumenfeld, Regional Administrator, 
EPA Region 9.
    \7\ See letter dated August 30, 2012 from Colleen Cripps, 
Administrator, NDEP, to Jared Blumenfeld, Regional Administrator, 
EPA Region 9.
---------------------------------------------------------------------------

    These submittals included cover letters from the NDEP Administrator 
to the Region IX Regional Administrator and tables for each air quality 
management jurisdiction in Nevada (i.e., NDEP, Clark County, and Washoe 
County Health District) that list and discuss how state and local 
provisions address the elements of CAA section 110(a)(2). Each 
submittal also includes attachments that, among other things, compile 
the State and local rules and statutes that are currently approved into 
the Nevada SIP or that apply locally and are supportive of Nevada 
meeting the infrastructure SIP requirements, and provide evidence of 
public notice and an opportunity for public comment or hearing prior to 
adoption and submittal of the SIP revisions. We find that these 
submittals meet the procedural requirements for public participation 
under CAA section 110(a)(2) and 40 CFR 51.102.
    We are proposing to act on all three submittals since they 
collectively address the infrastructure SIP requirements for the 2008 
Pb NAAQS. We refer to them collectively herein as ``Nevada's Pb 
Infrastructure Submittal.''

III. EPA's Evaluation and Proposed Action

    EPA has evaluated Nevada's Pb Infrastructure Submittal and the 
existing provisions of the Nevada SIP for compliance with the CAA 
section 110(a) requirements for the 2008 Pb NAAQS. Our Pb 
Infrastructure SIP Technical Support Document (``Pb TSD'') contains 
more detailed evaluations and is available in the public docket for 
this rulemaking, which may be accessed online at http://www.regulations.gov, docket number EPA-R09-OAR-2013-0663. We also rely 
on our technical support document (TSD) for the conflict of interest 
requirements of CAA sections 110(a)(2)(E)(ii) and 128 (``Section 128 
TSD''), which was prepared for our 2012 rulemaking on Nevada's 
infrastructure SIPs for the 1997 ozone, 1997 fine particulate 
(PM2.5), and 2006 PM2.5 NAAQS.\8\ That Section 
128 TSD is also included in the public docket for today's rulemaking.
---------------------------------------------------------------------------

    \8\ 77 FR 64737, October 23, 2012.
---------------------------------------------------------------------------

A. Proposed Approvals

    Based upon our evaluation as presented in the TSDs, EPA proposes to 
approve Nevada's Pb Infrastructure Submittal with respect to the 
following infrastructure SIP requirements:
     Section 110(a)(2)(A): Emission limits and other control 
measures.
     Section 110(a)(2)(B): Ambient air quality monitoring/data 
system.
     Section 110(a)(2)(C) (in part): Program for enforcement of 
control measures and regulation of new and modified stationary sources.
     Section 110(a)(2)(D)(i) (in part): Interstate pollution 
transport.
     Section 110(a)(2)(D)(ii) (in part): Interstate pollution 
abatement and international air pollution.
     Section 110(a)(2)(E): Adequate resources and authority, 
conflict of interest, and oversight of local and regional government 
agencies.
     Section 110(a)(2)(F) (in part): Stationary source 
monitoring and reporting.
     Section 110(a)(2)(G): Emergency episodes.
     Section 110(a)(2)(H): SIP revisions.
     Section 110(a)(2)(J) (in part): Consultation with 
government officials, public notification, and prevention of 
significant deterioration (PSD) and visibility protection.
     Section 110(a)(2)(K): Air quality modeling and submission 
of modeling data.
     Section 110(a)(2)(L): Permitting fees.
     Section 110(a)(2)(M): Consultation/participation by 
affected local entities.

B. Proposed Disapprovals

    EPA proposes to disapprove Nevada's Pb Infrastructure Submittal 
with respect to the following infrastructure SIP requirements (details 
of the partial disapprovals are presented after this list):
     Section 110(a)(2)(C) (in part): Program for enforcement of 
control measures and regulation of new and modified stationary sources.
     Section 110(a)(2)(D)(i) (in part): Interstate pollution 
transport.
     Section 110(a)(2)(D)(ii) (in part): Interstate pollution 
abatement and international air pollution.
     Section 110(a)(2)(F) (in part): Stationary source 
monitoring and reporting.
     Section 110(a)(2)(J) (in part): Consultation with 
government officials, public notification, and prevention of 
significant deterioration (PSD) and visibility protection.
    As explained more fully in our Pb TSD, we are proposing to 
disapprove the NDEP and Washoe County portions of Nevada's Pb 
Infrastructure Submittal with respect to the PSD-related requirements 
of sections 110(a)(2)(C), 110(a)(2)(D)(i)(II), 110(a)(2)(D)(ii), and 
110(a)(2)(J) because the Nevada SIP does not fully satisfy the 
statutory and regulatory requirements for PSD permit programs under 
part C, title I of the Act. Both NDEP and Washoe County AQMD currently 
implement the Federal PSD program in 40 CFR 52.21 for all regulated new 
source review (NSR) pollutants, pursuant to delegation agreements with 
EPA. See 40 CFR 52.1485.\9\ Accordingly, although the Nevada SIP 
remains deficient with respect to PSD requirements in both the NDEP and 
Washoe County portions of the SIP, these deficiencies are

[[Page 64433]]

adequately addressed in both areas by the federal PSD program.
---------------------------------------------------------------------------

    \9\ EPA fully delegated the implementation of the federal PSD 
programs to NDEP on October 19, 2004 (``Agreement for Delegation of 
the Federal Prevention of Significant Deterioration (PSD) Program by 
the United States Environmental Protection Agency, Region 9 to the 
Nevada Division of Environmental Protection''), as updated on 
September 15, 2011 and November 7, 2012, and to Washoe County on 
March 13, 2008 (``Agreement for Delegation of the Federal Prevention 
of Significant Deterioration (PSD) Program by the United States 
Environmental Protection Agency, Region 9 to the Washoe County 
District Health Department'').
---------------------------------------------------------------------------

    We are proposing to disapprove the Clark County portion of Nevada's 
Pb Infrastructure Submittal with respect to the PSD-related 
requirements of CAA sections 110(a)(2)(C), 110(a)(2)(D)(i)(II), and 
110(a)(2)(J) because Clark County's SIP-approved PSD permit program 
does not contain provisions that satisfy the statutory and regulatory 
requirements concerning condensable particulate matter (PM) and 
PM2.5 increments under part C, title I of the Act and in 40 
CFR 51.166.\10\ We address these PSD requirements as part of this 
proposal on Nevada's Pb Infrastructure Submittal for the 2008 Pb NAAQS 
because section 110(a)(2) of the Act requires that each SIP contain a 
comprehensive PSD permitting program that addresses all regulated NSR 
pollutants, including greenhouse gases (GHG).\11\ As explained in more 
detail below and in our Pb TSD, our proposed disapproval of the Clark 
County portion of Nevada's Pb Infrastructure Submittal based on these 
PSD program deficiencies would, if finalized, trigger a FIP obligation 
with respect to the requirements concerning PM2.5 increments 
in Clark County but would not trigger a FIP obligation with respect to 
the requirements concerning condensable PM, as a FIP clock to address 
this requirement has already been triggered by EPA's 2012 action on the 
NSR rules submitted for sources under Clark County's jurisdiction.\12\
---------------------------------------------------------------------------

    \10\ Requirements for condensable PM were promulgated in EPA's 
NSR/PSD implementation rule for the 1997 PM2.5 NAAQS. See 
73 FR 28321, May 16, 2008; codified at 40 CFR 51.166(b)(49). 
Requirements for PSD increments for PM2.5 were 
promulgated in EPA's PSD implementation rule for the 1997 
PM2.5 and 2006 PM2.5 NAAQS. See 75 FR 64864, 
October 10, 2010; codified at 40 CFR 51.166(c).
    \11\ The concept of a ``comprehensive'' PSD program (i.e., 
covering the PSD requirements for all regulated NSR pollutants, 
including GHGs) has been discussed in numerous infrastructure SIP 
rulemakings. See, e.g., EPA's final rule on Nevada's infrastructure 
SIP submittals for the 1997 ozone, 1997 PM2.5, and 2006 
PM2.5 NAAQS. 77 FR 64737 at 64738-64739, October 23, 
2012. This concept is also discussed in EPA's 2011 Pb Guidance, page 
6.
    \12\ 77 FR 64039, October 18, 2012.
---------------------------------------------------------------------------

    Our proposed disapprovals of the NDEP and Clark County portions of 
the Nevada Pb Infrastructure Submittal with respect to section 
110(a)(2)(C) also stem from unique circumstances regarding NDEP and 
Clark County's permit programs for the regulation of new and modified 
minor sources and minor modifications of major sources, herein referred 
to as ``minor NSR.'' Within this infrastructure SIP proposal, we are 
not proposing to approve or disapprove existing minor NSR regulations. 
However, in 2012, EPA finalized rulemakings on Nevada's submittals 
addressing minor NSR for sources under NDEP and Clark County DAQ 
jurisdiction, which included limited disapprovals.\13\ Upon review of 
those actions, we found that the NDEP and Clark County minor NSR 
programs lack provisions to address the 2008 Pb NAAQS. Accordingly, we 
cannot rely on NDEP and Clark County's existing minor NSR programs to 
ensure that new and modified sources not captured by the major NSR 
permitting programs do not interfere with attainment and maintenance of 
the 2008 Pb NAAQS. Therefore, with respect to section 110(a)(2)(C), we 
propose to find that the Nevada SIP does not meet the minor NSR program 
requirements for sources under NDEP and Clark County jurisdiction for 
the 2008 Pb NAAQS.
---------------------------------------------------------------------------

    \13\ Regarding NDEP's minor NSR permit program, see our proposal 
(77 FR 38557 at 38564, June 28, 2012) and final rules (77 FR 59321 
at 59325-59326, September 27, 2012). Regarding Clark County's permit 
program, see our proposed (77 FR 43206, July 24, 2012) and final 
rules (77 FR 64309, October 18, 2012). These final rules and their 
context specific to the 2008 Pb NAAQS are discussed further in our 
Pb TSD.
---------------------------------------------------------------------------

    As described in our Pb TSD, the resulting FIP obligations for these 
minor NSR program deficiencies have already been triggered by EPA's 
2012 actions on the NSR rules submitted for sources under NDEP \14\ and 
Clark County jurisdiction.\15\ As such, our proposed disapproval of 
Nevada's Pb Infrastructure Submittal with respect to the minor NSR 
requirement in CAA section 110(a)(2)(C) for the NDEP and Clark County 
portions of the Nevada SIP would not trigger a new FIP obligation 
because a FIP obligation already exists for the same identified SIP 
deficiencies.
---------------------------------------------------------------------------

    \14\ 77 FR 59321, September 27, 2012.
    \15\ 77 FR 64039, October 18, 2012.
---------------------------------------------------------------------------

    For the requirement of section 110(a)(2)(D)(i)(II) (regarding 
interference with other states' required measures to prevent 
significant deterioration of air quality), we propose to disapprove 
Nevada's Pb Infrastructure SIP for the reasons discussed above and in 
our Pb TSD in connection with the PSD-related requirements of CAA 
section 110(a)(2)(C).
    With respect to the requirement in CAA section 110(a)(2)(D)(ii) 
concerning compliance with section 126 requirements regarding 
interstate pollution abatement, EPA proposes to disapprove the NDEP and 
Washoe County portions of Nevada's Pb Infrastructure Submittal, for the 
reasons discussed above and in our Pb TSD in connection with the PSD-
related requirements of CAA section 110(a)(2)(C).
    For Section 110(a)(2)(F), we propose to disapprove the Clark County 
portion of Nevada's Pb Infrastructure Submittal with respect to 
subsection 110(a)(2)(F)(iii) because Clark County has repealed its 
regulation, Section 24, which formerly addressed the correlation 
requirement of this subsection, without submitting a SIP revision to 
replace it.
    As discussed in our Pb TSD, the resulting FIP obligation for this 
stationary source correlation requirement for the Clark County portion 
of the Nevada SIP has already been triggered by EPA's 2012 action on 
Nevada's infrastructure SIP submittals for the 1997 ozone, 1997 
PM2.5, and 2006 PM2.5 NAAQS.\16\ As such, we 
propose that this disapproval for section 110(a)(2)(F)(iii) for the 
Clark County portion of the Nevada SIP for the 2008 Pb NAAQS does not 
trigger a new FIP obligation because a FIP obligation already exists 
for the same identified SIP deficiency.
---------------------------------------------------------------------------

    \16\ 77 FR 64737, October 23, 2012.
---------------------------------------------------------------------------

    For the PSD related requirements of Section 110(a)(2)(J) we propose 
to disapprove Nevada's Pb Infrastructure Submittal for the reasons 
discussed above and in our Pb TSD in connection with the PSD-related 
requirements of section 110(a)(2)(C).
    EPA takes very seriously a proposal to disapprove a state plan, as 
we believe that it is preferable, and preferred in the provisions of 
the Clean Air Act, that these requirements be implemented through state 
plans. A state plan need not contain exactly the same provisions that 
EPA might require, but EPA must be able to find that the state plan is 
consistent with the requirements of the Act. Further, EPA's oversight 
role requires that it assure consistent implementation of Clean Air Act 
requirements by states across the country, even while acknowledging 
that individual decisions from source to source or state to state may 
not have identical outcomes. EPA believes these proposed disapprovals 
are the only path that is consistent with the Act at this time.

C. Consequences of Proposed Disapprovals

    Under section 179(a) of the CAA, final disapproval of a submittal 
that addresses a requirement of part D, title I of the CAA (CAA 
sections 171-193) or is required in response to a finding of 
substantial inadequacy as described in CAA section 110(k)(5) (SIP Call) 
starts a sanctions clock. Nevada's Pb Infrastructure Submittal was not 
submitted to meet either of these

[[Page 64434]]

requirements. Therefore, any action we take to finalize the described 
partial disapprovals will not trigger mandatory sanctions under CAA 
section 179.
    In addition, CAA section 110(c)(1) provides that EPA must 
promulgate a FIP within two years after finding that a State has failed 
to make a required submission or disapproving a State implementation 
plan submission in whole or in part, unless EPA approves a SIP revision 
correcting the deficiencies within that two-year period. As discussed 
in section III.B of this proposed rule and in our Pb TSD, we are 
proposing several partial disapprovals. With one exception, however, 
these disapprovals would not result in new FIP obligations, either 
because EPA has already promulgated a FIP to address the identified 
deficiency or because a FIP clock has been triggered by EPA's 
disapproval of a prior SIP submission based on the same identified 
deficiency. The provisions for which our proposed disapproval, if 
finalized, would not result in a new FIP obligation include:
     PSD-related requirements in sections 110(a)(2)(C), 
110(a)(2)(D)(i)(II), 110(a)(2)(D)(ii), and 110(a)(2)(J): For NDEP and 
Washoe County, EPA has already promulgated the federal PSD program (see 
40 CFR 52.1485);
     PSD-related requirements in sections 110(a)(2)(C), 
110(a)(2)(D)(i)(II), and 110(a)(2)(J): For Clark County, EPA's October 
18, 2012 final action on Clark County's PSD regulations triggered a 
November 19, 2014 deadline for EPA to promulgate a FIP addressing this 
requirement (77 FR 64039);
     Minor NSR requirement in section 110(a)(2)(C): EPA's 
September 27, 2012 final action on NDEP's minor NSR regulations (77 FR 
59321) and October 18, 2012 final action on Clark County's minor NSR 
regulations (77 FR 64039) triggered deadlines of October 29, 2014 and 
November 19, 2014, respectively, for EPA to promulgate FIPs addressing 
the identified deficiencies;
     Section 110(a)(2)(F)(iii): For Clark County, EPA's October 
23, 2012 final action on Nevada's Infrastructure SIP submittals for the 
1997 ozone, 1997 PM2.5, and 2006 PM2.5 NAAQS (77 
FR 64737) triggered a November 23, 2014 deadline for EPA to promulgate 
a FIP addressing the requirement for correlation of stationary source 
emissions with emission limits.
    The one disapproval that would trigger a new FIP clock concerns the 
requirement under sections 110(a)(2)(C), 110(a)(2)(D)(i)(II) and 
110(a)(2)(J) regarding PSD increments for PM2.5 in Clark 
County. EPA has not previously promulgated a FIP or triggered a FIP 
clock through disapproval of a prior SIP submission based on this 
deficiency. Thus, under CAA section 110(c)(1), our partial disapproval 
of the Clark County portion of Nevada's Pb Infrastructure Submittal 
based on this deficiency would, if finalized, require EPA to promulgate 
a FIP establishing PM2.5 increments for Clark County within 
two years after the effective date of our final rule, unless the State 
submits and EPA approves a SIP revision that corrects this deficiency 
prior to the expiration of this two-year period.
    We anticipate that NDEP will submit SIP revisions that adequately 
address the deficiencies identified in EPA's 2012 actions on NDEP's 
minor NSR program, Clark County's permit program (i.e., both PSD and 
minor NSR), Nevada's infrastructure SIPs for the 1997 ozone, 1997 
PM2.5, and 2006 PM2.5 NAAQS, and today's proposed 
action on Nevada's Pb Infrastructure Submittal prior to expiration of 
the 2-year FIP deadline triggered by each of these actions. We further 
anticipate that EPA approval of such revisions would also serve to 
adequately address the partial disapprovals of the Nevada Pb 
Infrastructure SIP where no FIP is currently in place (i.e., the 
disapprovals proposed herein, except for those tied to the federal PSD 
programs for sources under NDEP and Washoe County Health District's 
jurisdiction). We stand ready to work with the State of Nevada to 
develop such SIP revisions.

IV. Statutory and Executive Order Reviews

Executive Order 12866, Regulatory Planning and Review

    This action is not a ``significant regulatory action'' under the 
terms of Executive Order (EO) 12866 (58 FR 51735, October 4, 1993) and 
is therefore not subject to review under the EO.

Paperwork Reduction Act

    This action does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq, 
because this proposed partial approval and partial disapproval of SIP 
revisions under CAA section 110 will not in-and-of itself create any 
new information collection burdens but simply proposes to approve 
certain State requirements, and to disapprove certain other State 
requirements, for inclusion into the SIP. Burden is defined at 5 CFR 
1320.3(b).

Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to conduct a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements unless the agency certifies 
that the rule will not have a significant economic impact on a 
substantial number of small entities. Small entities include small 
businesses, small not-for-profit enterprises, and small governmental 
jurisdictions. For purposes of assessing the impacts of today's rule on 
small entities, small entity is defined as: (1) A small business as 
defined by the Small Business Administration's (SBA) regulations at 13 
CFR 121.201; (2) a small governmental jurisdiction that is a government 
of a city, county, town, school district or special district with a 
population of less than 50,000; and (3) a small organization that is 
any not-for-profit enterprise which is independently owned and operated 
and is not dominant in its field.
    After considering the economic impacts of today's proposed rule, we 
certify that this proposed action will not have a significant impact on 
a substantial number of small entities. This proposed rule does not 
impose any requirements or create impacts on small entities. This 
proposed partial SIP approval and partial SIP disapproval under CAA 
section 110 will not in-and-of itself create any new requirements but 
simply proposes to approve certain State requirements, and to 
disapprove certain other State requirements, for inclusion into the 
SIP. Accordingly, it affords no opportunity for EPA to fashion for 
small entities less burdensome compliance or reporting requirements or 
timetables or exemptions from all or part of the rule. Therefore, this 
action will not have a significant economic impact on a substantial 
number of small entities.
    We continue to be interested in the potential impacts of this 
proposed rule on small entities and welcome comments on issues related 
to such impacts.

Unfunded Mandates Reform Act

    This action contains no Federal mandates under the provisions of 
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 
1531-1538 for State, local, or tribal governments or the private 
sector. EPA has determined that the proposed partial approval and 
partial disapproval action does not include a Federal mandate that may 
result in estimated costs of $100 million or more to either State, 
local, or tribal governments in the aggregate, or to the private 
sector. This action proposes to approve certain pre-existing 
requirements, and to disapprove certain other pre-existing 
requirements, under State or local law,

[[Page 64435]]

and imposes no new requirements. Accordingly, no additional costs to 
State, local, or tribal governments, or to the private sector, result 
from this proposed action.

Executive Order 13132, Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that 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.''
    This action does not have federalism implications. It will 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, because it merely proposes to 
approve certain State requirements, and to disapprove certain other 
State requirements, for inclusion into the SIP and does not alter the 
relationship or the distribution of power and responsibilities 
established in the Clean Air Act. Thus, Executive Order 13132 does not 
apply to this action.

Executive Order 13175, Coordination With Indian Tribal Governments

    This action does not have tribal implications, as specified in 
Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP 
on which EPA is proposing action would not 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. Thus, 
Executive Order 13175 does not apply to this proposed action.

Executive Order 13045, Protection of Children From Environmental Health 
Risks and Safety Risks

    EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) 
as applying only to those regulatory actions that concern health or 
safety risks, such that the analysis required under section 5-501 of 
the Executive Order has the potential to influence the regulation. This 
proposed action is not subject to Executive Order 13045 because it is 
not an economically significant regulatory action based on health or 
safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 
1997). This proposed partial approval and partial disapproval under CAA 
section 110 will not in-and-of itself create any new regulations but 
simply proposes to approve certain State requirements, and to 
disapprove certain other State requirements, for inclusion into the 
SIP.

Executive Order 13211, Actions That Significantly Affect Energy Supply, 
Distribution, or Use

    This proposed rule is not subject to Executive Order 13211 (66 FR 
28355, May 22, 2001) because it is not a significant regulatory action 
under Executive Order 12866.

National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note) 
directs EPA to use voluntary consensus standards in its regulatory 
activities unless to do so would be inconsistent with applicable law or 
otherwise impractical. Voluntary consensus standards are technical 
standards (e.g., materials specifications, test methods, sampling 
procedures, and business practices) that are developed or adopted by 
voluntary consensus standards bodies. NTTAA directs EPA to provide 
Congress, through OMB, explanations when the Agency decides not to use 
available and applicable voluntary consensus standards.
    The EPA believes that this proposed action is not subject to 
requirements of Section 12(d) of NTTAA because application of those 
requirements would be inconsistent with the Clean Air Act.

Executive Order 12898: Federal Actions To Address Environmental Justice 
in Minority Populations and Low-Income Population

    Executive Order 12898 (59 FR 7629 (Feb. 16, 1994)) establishes 
federal executive policy on environmental justice. Its main provision 
directs federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority populations and low-income 
populations in the United States.
    EPA lacks the discretionary authority to address environmental 
justice in this proposed rulemaking.
