Approval and Promulgation of Air Quality Implementation Plans; 
Louisiana; Infrastructure State Implementation Plan Requirements for 
the National Ambient Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve elements of a State Implementation Plan (SIP) submission from 
the State of Louisiana for National Ambient Air Quality Standards 
(NAAQS) for fine particulate matter (PM2.5), lead (Pb), 
ozone (O3), nitrogen dioxide (NO2), and sulfur 
dioxide (SO2). This submission addresses how the existing 
SIP provides for implementation, maintenance, and enforcement of the 
NAAQS for these pollutants (also referred to as an infrastructure SIP 
or i-SIP). These i-SIPs ensure that the State's SIP is adequate to meet 
the state's responsibilities under the Federal Clean Air Act (CAA).

I. Background

    On October 17, 2006, following a periodic review of the NAAQS for 
PM2.5, EPA revised the PM 2.5 NAAQS.\1\ The 24-
hour standard was revised to 35 micrograms per cubic meter ([mu]g/
m\3\), and the annual standard was revised to 15 [mu]g/m\3\ (71 FR 
61144). On December 14, 2012, we promulgated a revised primary annual 
PM2.5 NAAQS (78 FR 3086). The primary annual standard was 
revised to 12.0 [mu]g/m\3\, and we retained the 24-hour 
PM2.5 standard of 35 [mu]g/m\3\ (78 FR 3086). In 2008, 
following a periodic review of the NAAQS for Pb, we revised the NAAQS 
to 0.15 [mu]g/m\3\ for both the primary and secondary standards (73 FR 
66964). On March 27, 2008, following a periodic review, EPA revised the 
primary and secondary O3 NAAQS (73 FR 16205) to establish a 
new primary standard of 0.075 parts per million (ppm), expressed to 
three decimal places, based on a 3-year average of the fourth-highest 
maximum 8-hour average concentration, and revised the current 8-hour 
standard by making it identical to the revised primary standard.

this review; the specific i-SIP applicable CAA and EPA regulatory 
citation; Federal Register Louisiana minor New Source Review program 
and EPA approval activities; and Louisiana's Prevention of 
Significant Deterioration (PSD) program can be found in the 
Technical Support Document (TSD).
---------------------------------------------------------------------------

    Likewise, on February 9, 2010, EPA revised the primary national 
ambient air quality standard for oxides of nitrogen as measured by 
nitrogen dioxide (NO2), for 1-hour standard at a level of 
100 ppb, based on the 3-year average of the 98th percentile of the 
yearly distribution of 1-hour daily maximum concentrations, to 
supplement the existing annual standard (75 FR 6474). EPA also 
established requirements for an NO2 monitoring network that 
includes monitors at locations where maximum NO2 
concentrations are expected to occur, including within 50 meters of 
major roadways, as well as monitors sited to measure the area-wide 
NO2 concentrations that occur more broadly across 
communities. (75 FR 6474).
    Additionally, on June 22, 2010, the EPA revised the primary 
SO2 NAAQS to establish a new 1-hour standard, with a level 
of 75 ppb, based on the 3-year average of the annual 99th percentile of 
1-hour daily maximum concentrations (75 FR 35520).
    Each state must submit an i-SIP within three years after the 
promulgation of a new or revised NAAQS. Section 110(a)(2) of the CAA 
includes a list of specific elements the i-SIP must meet. In an effort 
to assist states in complying with this requirement, EPA issued 
guidance addressing the i-SIP elements for NAAQS.\2\

Elements under Clean Air Act sections 110(a)(1) and 110(a)(2),'' 
Memorandum from Stephen D. Page, September 13, 2013.
---------------------------------------------------------------------------

    The Secretary of the Louisiana Department of Environmental Quality 
(LDEQ) submitted i-SIP revisions to address the revised NAAQS.
    With the exception of the certain portions that pertain to 
interstate transport, EPA is proposing to approve the Louisiana i-SIP 
submittals for these pollutant NAAQS.\3\ The exceptions are (1) the 
portions of the 2008 ozone NAAQS submittal that pertain to interstate 
transport of Louisiana emissions which will significantly contribute to 
nonattainment of the NAAQS in other states, (2) the portion of the 2010 
SO2 NAAQS submittal that pertains to interstate transport of 
Louisiana emissions to other states, and (3) the portions which will 
interfere with visibility protection measures in other states for the 
2006 and 2012 PM2.5, 2008 Pb, 2008 O3, 2010 
NO2, and 2010 SO2 NAAQS. We will take 
separate action on the portions of the 2008 ozone and 2010 
SO2 NAAQS submittal that pertain to significant contribution 
to nonattainment or interference with maintenance of the NAAQS in other 
states. We have disapproved portions of the Louisiana Regional Haze 
Plan submittal that pertain to interference with visibility protection 
measures in other states (77 FR 39425). LDEQ and EPA are currently 
working on a revised Louisiana Regional Haze Plan.

II. EPA's Evaluation of Louisiana's NAAQS Infrastructure Submissions

    Below is a summary of EPA's evaluation of the Louisiana i-SIP for 
each applicable element of 110(a)(2) A-M.\4\ Louisiana provided a 
demonstration of how the existing Louisiana SIP meets the requirements 
of the 2006 PM2.5 NAAQS, on May 11, 2011; 2008 Pb NAAQS on 
October 14, 2011; 2008 O3, 2010 NO2, 2010 
SO2 NAAQS on June 7, 2013 and the 2012 PM2.5 
NAAQS on December 16, 2015. The 2006 PM2.5, 2008 Pb, 2008 
O3, 2010 NO2 and 2010 SO2 SIP 
submissions are complete by operation of law.\5\ The 2012 
PM2.5 submission was reviewed and determined to be complete.
---------------------------------------------------------------------------

    \4\ A detailed discussion of our evaluation can be found in the 
TSD for this action. The TSD can be accessed through 
www.regulations.gov (e-docket EPA-R06-OAR-2013-0465).
    \5\ These SIP submissions became complete by operation of law on 
November 11, 2012 (2006 PM2.5), April 14, 2012 (2008 Pb), 
and December 7, 2013 (2008 O3, 2010 NO2, and 
2010 SO2). See CAA section 110(k)(1)(B).
---------------------------------------------------------------------------

    (A) Emission limits and other control measures: The SIP must 
include enforceable emission limits and other control measures, means 
or techniques, schedules for compliance and other related matters as 
needed to implement,

[[Page 35676]]

maintain and enforce each of the NAAQS.\6\ The Louisiana Air Control 
Law found in the Louisiana Environmental Quality Act at Louisiana 
Revised Statute (La R.S.)30:2054 provides the Secretary of the 
Department of Environmental Quality with broad legal authority. The 
Secretary can adopt emission standards and compliance schedules which 
are applicable to regulated entities; emission standards and 
limitations and any other measures necessary for attainment and 
maintenance of national standards. The Secretary can also enforce 
applicable laws, regulations, standards and compliance schedules, and 
seek injunctive relief. This authority has been employed in the past to 
adopt and submit multiple revisions to the Louisiana State 
Implementation Plan. The approved SIP for Louisiana is documented at 40 
CFR part 52.970, subpart T.\7\ LDEQ's air quality rules and standards 
are codified at Title 33, Part III of the Louisiana Administrative Code 
(LAC). Numerous parts of the regulations codified into 33 LAC necessary 
for implementing and enforcing the NAAQS have been adopted into the 
SIP.\8\
---------------------------------------------------------------------------

    \6\ The specific nonattainment area plan requirements of section 
110(a)(2)(I) are subject to the timing requirements of section 172, 
not the timing requirement of section 110(a)(1). Thus, section 
110(a)(2)(A) does not require that states submit regulations or 
emissions limits specifically for attaining the 2006 
PM2.5, 2008 Pb, 2008 O3, 2010 NO2, 
2010 SO2 or 2012 PM2.5 NAAQS. Those SIP 
provisions are due as part of each state's attainment plan, and will 
be addressed separately from the requirements of section 
110(a)(2)(A). In the context of an infrastructure SIP, EPA is not 
evaluating the existing SIP provisions for this purpose. Instead, 
EPA is only evaluating whether the state's SIP has basic structural 
provisions for the implementation of the NAAQS.

    \8\ See the TSD for additional information.
---------------------------------------------------------------------------

    (B) Ambient air quality monitoring/data system: The SIP must 
provide for: Establishment and implementation of ambient air quality 
monitors, collection and analysis of ambient air quality data, and 
authority to provide such data to EPA upon request.
    The La R.S. Chapter 2 provides LDEQ with the authority to collect 
air quality monitoring data, quality-assure the results, and report the 
data. LDEQ maintains and operates a monitoring network to measure 
levels of the pollutants in accordance with EPA regulations specifying 
siting and monitoring requirements. All monitoring data is measured 
using EPA approved methods and subject to the EPA quality assurance 
requirements. LDEQ submits all required data to EPA, following the EPA 
regulations. The monitoring network was approved into the SIP and it 
undergoes recurrent annual review by EPA.\9\ In addition, LDEQ conducts 
a recurrent assessment of its monitoring network every five years, as 
required by EPA rules. The most recent of these 5-year monitoring 
network assessments was conducted by LDEQ and approved by EPA.\10\ The 
LDEQ Web site provides the monitor locations and posts past and current 
concentrations of criteria pollutants measured in the State's network 
of monitors.\11\
---------------------------------------------------------------------------

    \9\ A copy of the 2015 Annual Air Monitoring Network Plan and 
EPA's approval letter are included in the docket for this proposed 
rulemaking.
    \10\ A copy of LDEQ's 2010 5-year ambient monitoring network 
assessment and EPA's approval letter are included in the docket for 
this proposed rulemaking.
    \11\ See https://airquality.deq.louisiana.gov/ and https://www.deq.louisiana.gov/portal/DIVISIONS/Assessment/AirFieldServices/AmbientAirMonitoringProgram/AmbientAirMonitoringDataandReports.aspx.
---------------------------------------------------------------------------

    (C) Program for enforcement of control measures: The SIP must 
include the following three elements: (1) A program providing for 
enforcement of the measures in paragraph A above; (2) a program for the 
regulation of the modification and construction of stationary sources 
as necessary to protect the applicable NAAQS (i.e., state-wide 
permitting of minor sources); and (3) a permit program to meet the 
major source permitting requirements of the CAA (for areas designated 
as attainment or unclassifiable for the NAAQS in question).\12\
---------------------------------------------------------------------------

    \12\ As discussed in further detail in the TSD.
---------------------------------------------------------------------------

    (1) Enforcement of SIP Measures. As noted in (A), the state 
statutes provide authority for the LDEQ and its Secretary to enforce 
the requirements of the LAC, and any regulations, permits, or final 
compliance orders. These statutes also provide the LDEQ and its 
Secretary with general enforcement powers. Among other things, they can 
file lawsuits to compel compliance with the statutes and regulations; 
commence civil actions; issue field citations; conduct investigations 
of regulated entities; collect criminal and civil penalties; develop 
and enforce rules and standards related to protection of air quality; 
issue compliance orders; pursue criminal prosecutions; investigate, 
enter into remediation agreements; and issue emergency cease and desist 
orders. The LAC also provides additional enforcement authorities and 
funding mechanisms.
    (2) Minor New Source Review. The SIP is required to include 
measures to regulate construction and modification of stationary 
sources to protect the NAAQS. The Louisiana minor NSR permitting 
requirements are approved as part of the SIP.\13\
---------------------------------------------------------------------------

    \13\ EPA is not proposing to approve or disapprove the existing 
Louisiana minor NSR program to the extent that it may be 
inconsistent with EPA's regulations governing this program. EPA has 
maintained that the CAA does not require that new infrastructure SIP 
submissions correct any defects in existing EPA-approved provisions 
of minor NSR programs in order for EPA to approve the infrastructure 
SIP for element C (e.g., 76 FR 41076-41079, July 13 2011). EPA 
believes that a number of states may have minor NSR provisions that 
are contrary to the existing EPA regulations for this program. The 
statutory requirements of section 110(a)(2)(C) provide for 
considerable flexibility in designing minor NSR programs.
---------------------------------------------------------------------------

    (3) Prevention of Significant Deterioration (PSD) permit program. 
The Louisiana PSD portion of the SIP covers all NSR regulated 
pollutants and has been approved by EPA.\14\
---------------------------------------------------------------------------

    \14\ As discussed further in the TSD.
---------------------------------------------------------------------------

    (D)(i) Interstate Pollution Transport: The i-SIP must prohibit 
emissions within Louisiana from contributing significantly to the 
nonattainment of the NAAQS in other states, and from interfering with 
the maintenance of the NAAQS in other states (CAA(a)(2)(D)(i)(I)). The 
SIP must also prohibit emissions within Louisiana both from interfering 
with measures required to prevent significant deterioration in other 
states and from interfering with measures required to protect 
visibility in other states (CAA(a)(2)(D)(i)(II)).
    Fine Particulate Matter: Previously we approved the portion of 
Louisiana's 2006 PM2.5 NAAQS i-SIP which addressed the 
requirement that emissions within Louisiana be prohibited from 
contributing to the nonattainment of the NAAQS in other states, and 
from interfering with the maintenance of the NAAQS in other states (79 
FR 4436). We are not acting on the nonattainment/maintenance component 
for the 2012 PM2.5 NAAQS at this time. We expect to propose 
an action at a later date.
    Based on information presented in this submission, we are approving 
the portion of the i-SIP submittal for both the 2006 PM2.5 
NAAQS and the 2012 PM2.5 NAAQS which addresses the 
prevention of interference with PSD programs in other states. Louisiana 
has a fully acceptable PSD program. The program regulates all NSR 
pollutants, including greenhouse gas (GHG) which prevents significant 
deterioration in nearby states. Since Louisiana's Regional Haze Plan 
was not fully approved, we are disapproving the portion of the i-SIP 
which addresses the prevention of interference with measures required 
to protect visibility

[[Page 35677]]

in other states for both the 2006 PM2.5 NAAQS and the 2012 
PM2.5 NAAQS. We cannot ensure that Louisiana emissions will 
not interfere with visibility protection measures in other States.
    Lead: We propose to approve the portion of the submittal which 
addresses the requirement that emissions within Louisiana be prohibited 
from contributing to the nonattainment of the Pb NAAQS in other states, 
and from interfering with the maintenance of the Pb NAAQS in other 
states. The physical properties of Pb, which is a metal and very dense, 
prevent Pb emissions from experiencing a significant degree of travel 
in the ambient air. No complex chemistry is needed to form Pb or Pb 
compounds in the ambient air; therefore, ambient concentrations of Pb 
are typically highest near Pb sources. More specifically, there is a 
sharp decrease in ambient Pb concentrations as the distance from the 
source increases. According to EPA's report entitled Our Nation's Air: 
Status and Trends Through 2010, Pb concentrations that are not near a 
source of Pb are approximately 8 times less than the typical 
concentrations near the source.\15\ There are no areas within the State 
of Louisiana designated as nonattainment with respect to the 2008 lead 
NAAQS. LDEQ's 2015 ambient monitoring plan provided information on 
significant lead sources and their location. There are two significant 
sources of Pb emissions within the state that emit more than Pb in 
amounts equal to or exceeding 0.5 tons per year and no sources within 
two miles of a neighboring state line.
---------------------------------------------------------------------------

    \15\ https://www.epa.gov/airtrends/2011/report/fullreport.pdf.
---------------------------------------------------------------------------

    We are also proposing to approve the portion pertaining to the 
prevention of significant deterioration in other states for lead, as 
Louisiana has a fully acceptable PSD program. The program regulates all 
NSR pollutants, including greenhouse gas (GHG) which prevents 
significant deterioration in nearby States.
    Significant impacts from Pb emissions from stationary sources are 
limited to short distances from emitting sources, therefore, visibility 
is not effected by lead emissions.\16\ Given this information, we 
propose to approve the portion of the Pb i-SIP submittal related to the 
protection of visibility in other states.
---------------------------------------------------------------------------

    \16\ More information about this is provided in the TSD.
---------------------------------------------------------------------------

    Ozone: At this time we are not proposing action on the i-SIP 
submittals which address the prevention of emissions which 
significantly contribute to the nonattainment of the ozone NAAQS in 
other states, and the interference with the maintenance of the ozone 
NAAQS in other states. We plan to act on this portion of the i-SIP in a 
separate action.
    Based on information presented in this submission, we are proposing 
to approve the portion of the submittal related to the prevention of 
significant deterioration in other states, as Louisiana has a fully 
acceptable PSD program. The program regulates all NSR pollutants, 
including greenhouse gas (GHG) which prevents significant deterioration 
in nearby states. Since Louisiana's Regional Haze Plan was not fully 
approved, we also are disapproving the portion of the submittal related 
to the protection of visibility in other states.
    Nitrogen Dioxide: We propose to approve the portion of the 
submittal which addresses the prevention of emissions which 
significantly contribute to the nonattainment of the NO2 
NAAQS in other states and interfere with the maintenance of the 
NO2 NAAQS in other states. On February 17, 2012, EPA 
designated the entire country as ``unclassifiable/attainment'' for the 
2010 NO2.\17\ The available air quality data show that all 
areas in the country meet the 2010 NO2 NAAQS for 2008-2010. 
No state or tribal entity recommended an area be designated 
``nonattainment.'' As listed in our NO2 Design Values 
report,\18\ only one maintenance area exists for the prior annual 
NO2 NAAQS (Los Angeles, California). With no nonattainment 
or maintenance areas in surrounding states, Louisiana does not 
significantly contribute to nonattainment or maintenance of these NAAQS 
in any of the contiguous states. As further evidence that Louisiana's 
NO2 emissions do not contribute to nonattainment or 
maintenance of NAAQS, we reviewed more recent monitoring data for 
NO2 throughout the United States. Using previous EPA 
methodology,\19\ we evaluated specific monitors identified as having 
nonattainment and or maintenance problems, which we refer to as 
``receptors''. We identify nonattainment receptors as any monitor that 
violated the NO2 NAAQS in the most recent three year period. 
Meanwhile, we identify NO2 maintenance receptors as any 
monitor that violated the NO2 NAAQS in either of the prior 
monitoring cycles (2010-2012 and 2011-2013), but attained in the most 
recent monitoring cycle (2012-2014). During the three most recent 
design value periods of 2010 through 2012, 2011 through 2013 and 2012 
through 2014, we found no monitors violating the 2010 NO2 
NAAQS in the U.S.

State Air Pollution Rule 76 FR 48208 (August 8, 2001).
---------------------------------------------------------------------------

    We are approving the portion of the submittal related to the 
prevention of significant deterioration in other states, as Louisiana 
has a fully acceptable PSD program. The program regulates all NSR 
pollutants, including greenhouse gas (GHG) which prevents significant 
deterioration in nearby states. Since Louisiana's Regional Haze Plan 
was not fully approved, we also are not approving the portion of the 
submittal related to the protection of visibility in other states.
    Sulfur Dioxide: At this time we not taking action on the portion of 
the submittal which addresses the prevention of emissions which 
significantly contribute to the nonattainment of the SO2 
NAAQS in other states and interfere with the maintenance of the 
SO2 NAAQS in other states. We expect to take action on this 
portion of the SIP submittal at a later time.
    (D)(ii) Interstate Pollution Abatement and International Air 
Pollution: In addition, states must comply with the requirements listed 
in sections 115 and 126 of the CAA which were designed to aid in the 
abatement of interstate and international pollution (CAA 
110(a)(2)(D)(ii)). Section 126(a) requires new or modified sources to 
notify neighboring states of potential impacts from the source. 
Louisiana's PSD program contains the element pertaining to notification 
to neighboring states of the issuance of PSD permits. Section 115 
relates to international pollution abatement. As there are no findings 
by EPA that air emissions originating in Louisiana affect other 
countries, we propose to approve the portions of the i-SIPs pertaining 
to CAA section 110(a)(2)(D)(ii).
    (E) Adequate authority, resources, implementation, and oversight: 
The SIP must provide for the following: (1) Necessary assurances that 
the state (and other entities within the state responsible for 
implementing the SIP) will have adequate personnel, funding, and 
authority under state or local law to implement the SIP, and that there 
are no legal impediments to such implementation; (2) compliance with 
requirements relating to state boards as explained in section 128 of 
the CAA; and (3) necessary assurances that the state has responsibility 
for ensuring

[[Page 35678]]

adequate implementation of any plan provision for which it relies on 
local governments or other entities to carry out. Both elements (A) and 
(E) address the state have adequate authority to implement and enforce 
the SIP without legal impediments.
    The i-SIP submissions for these pollutants describe the SIP 
regulations governing the various functions of personnel within the 
LDEQ, including the administrative, technical support, planning, 
enforcement, and permitting functions of the program.
    With respect to funding, La R.S. 30:2011 and the SIP require LDEQ 
to establish an emissions fee schedule for sources in order to fund the 
reasonable costs of administering various air pollution control 
programs and authorizes LDEQ to collect additional fees necessary to 
cover reasonable costs associated with processing of air permit 
applications. EPA conducts periodic program reviews to ensure that the 
state has adequate resources and funding to, among other things, 
implement and enforce the SIP.
    As required by the CAA and the SIP, the majority of the members 
that compose any board or body which approves permits or enforcement 
orders must not derive any ``significant portion'' of their income from 
persons subject to permits and enforcement orders or persons who appear 
before the board on issues related to the CAA or the Louisiana Air 
Quality Rules (La. R.S. 2014.1). The members of the board or body, or 
the head of an agency with similar powers, are required to adequately 
disclose any potential conflicts of interest.
    Louisiana has not delegated any authority to implement any of the 
provisions of its plan to local governmental entities. The LDEQ acts as 
the primary air pollution control agency.
    (F) Stationary source monitoring system: The SIP must provide for 
the establishment of a system to monitor emissions from stationary 
sources and to submit periodic emission reports. It must require the 
installation, maintenance, and replacement of equipment, and the 
implementation of other necessary steps, by owners or operators of 
stationary sources, to monitor emissions from such sources. The SIP 
shall also require periodic reports on the nature and amounts of 
emissions and emissions-related data from such sources. It shall 
require that the state correlate the source reports with emission 
limitations or standards established under the CAA. These reports must 
be made available for public inspection at reasonable times.
    LAC 33:III Chapter 9 authorizes the LDEQ to require persons engaged 
in operations which result in air pollution to monitor or test 
emissions and to file reports containing information relating to the 
nature and amount of emissions. There are also SIP-approved state 
regulations pertaining to sampling and testing and requirements for 
reporting of emissions inventories (60 FR 02014). In addition, SIP-
approved rules establish general requirements for maintaining records 
and reporting emissions.
    The LDEQ uses this information, in addition to information obtained 
from other sources, to track progress towards maintaining the NAAQS, 
develop control and maintenance strategies, identify sources and 
general emission levels, and determine compliance with SIP-approved 
regulations and additional EPA requirements. The SIP requires this 
information be made available to the public. Provisions concerning the 
handling of confidential data and proprietary business information are 
included in the SIP-approved regulations. These rules specifically 
exclude from confidential treatment any records concerning the nature 
and amount of emissions reported by sources.
    (G) Emergency authority: The SIP must provide the LDEQ with 
authority to restrain any source from causing imminent and substantial 
endangerment to public health or welfare or the environment. The SIP 
must include an adequate contingency plan to implement LDEQ's emergency 
authority.
    La R.S 30:2011.D.15 provides LDEQ with the required authority to 
address environmental emergencies, and LDEQ has contingency plans to 
implement the emergency episode provisions in the SIP. The LDEQ 
promulgated the ``Prevention of Air Pollution Emergency Episodes,'' 
which includes contingency measures, and these provisions were approved 
into the SIP in 1989 (54 FR 9783). The episode criteria and contingency 
measures are found in 33 LAC Chapter 56.
    Louisiana has general emergency powers to address any possible 
dangerous air pollution episode if necessary to protect the environment 
and public health.
    (H) Future SIP revisions: States must have the authority to revise 
their SIPs in response to changes in the NAAQS, availability of 
improved methods for attaining the NAAQS, or in response to an EPA 
finding that the SIP is substantially inadequate to attain the NAAQS.
    La R.S. 30:2011 authorizes the LDEQ to revise the Louisiana SIP, as 
necessary, to account for revisions of an existing NAAQS, establishment 
of a new NAAQS, to attain and maintain a NAAQS, to abate air pollution, 
to adopt more effective methods of attaining a NAAQS, and to respond to 
EPA SIP calls concerning NAAQS adoption or implementation.
    (I) Nonattainment areas: The CAA section 110(a)(2)(I) requires that 
in the case of a plan or plan revision for areas designated as 
nonattainment areas, states must meet applicable requirements of part D 
of the CAA, relating to SIP requirements for designated nonattainment 
areas.
    However, as noted earlier, EPA believes that nonattainment area 
requirements should be treated separately from the infrastructure SIP 
requirements. The specific SIP submissions for designated nonattainment 
areas, as required under CAA title I, part D, are subject to different 
submission schedules than those for section 110 infrastructure 
elements. Instead, EPA will take action on part D attainment plan SIP 
submissions through a separate rulemaking process governed by the 
requirements for nonattainment areas, as described in part D.\20\
---------------------------------------------------------------------------

    \20\ This infrastructure SIP rulemaking will not address the 
Louisiana program for provisions related to nonattainment areas, 
since EPA considers evaluation of these provisions to be outside the 
scope of infrastructure SIP actions.
---------------------------------------------------------------------------

    (J) Consultation with government officials, public notification, 
PSD and visibility protection: The SIP must meet the following four CAA 
requirements: (1) Those listed in section 121 of the CAA, relating to 
interagency consultation; (2) those listed in section 127, relating to 
public notification of NAAQS exceedances and related issues; (3) 
prevention of significant deterioration of air quality and (4) 
visibility protection.
    (1) Interagency consultation: As required by the LAC, there must be 
a public hearing before the adoption of any regulations or emission 
control requirements, and all interested persons are given a reasonable 
opportunity to review the action that is being proposed and to submit 
data or arguments, either orally or in writing, and to examine 
witnesses testifying at the hearing (La R.S. 30:2011). In addition, the 
LAC provides the LDEQ the power and duty to establish cooperative 
agreements with local authorities, and consult with other states, the 
federal government and other interested persons or groups in regard to 
matters of common interest in the field of air quality control (La. 
R.S. 30:2032). Furthermore, the Louisiana PSD SIP rules mandate that 
the LDEQ provide for

[[Page 35679]]

public participation and notification regarding permitting applications 
to any other state or local air pollution control agencies, local 
government officials of the city or county where the source will be 
located, tribal authorities, and Federal Land Manager (FLMs) whose 
lands may be affected by emissions from the source or modification (LAC 
33:III.509). Additionally, the State's PSD SIP rules require the LDEQ 
to consult with FLMs regarding permit applications for sources with the 
potential to impact Class I Federal Areas. The SIP also includes a 
commitment to consult continually with the FLMs on the review and 
implementation of the visibility program. Louisiana recognizes the 
expertise of the FLMs in monitoring, as well as new source review 
applicability analyses for visibility. The State has agreed to notify 
the FLMs of any advance notification or early consultation with a new 
or modifying source prior to the submission of a permit application. 
Likewise, the State's Transportation Conformity SIP rules provide for 
interagency consultation, resolution of conflicts, and public 
notification.
    (2) Public Notification: On January 10, 1980, the Governor 
submitted final revisions to the ambient monitoring portion of the 
plan. These revisions were included into the SIP on August 6, 1981 (46 
FR 40005). This portion of the SIP includes requirements for public 
notification of information related to air quality standards violation 
included in Part 51 in order to meet the requirements of Section 127 of 
the Act, requiring the LDEQ to regularly notify the public of instances 
or areas in which any NAAQS are exceeded. In addition, as discussed for 
infrastructure element B above, the LDEQ air monitoring Web site 
provides quality data for each of the monitoring stations in Louisiana; 
this data is provided instantaneously for certain pollutants, such as 
ozone. The Web site also provides information on the health effects of 
lead, ozone, particulate matter, and other criteria pollutants.
    (3) PSD and Visibility Protection: The PSD requirements for this 
element are the same as those addressed under element (C) above. As was 
mentioned earlier, the State has a PSD program, so this requirement has 
been met. The Louisiana SIP requirements relating to visibility and 
regional haze are not affected when EPA establishes or revises a NAAQS. 
Therefore, EPA believes that there are no new visibility protection 
requirements due to the revision of the NAAQS, and consequently there 
are no newly applicable visibility protection obligations pursuant to 
infrastructure element (J).
    (K) Air quality and modeling/data: The SIP must provide for 
performing air quality modeling, as prescribed by EPA, to predict the 
effects on ambient air quality of any emissions of any NAAQS pollutant, 
and for submission of such data to EPA upon request.
    The LDEQ has the power and duty, under La R.S. 30:2011 et seq. to 
develop facts and investigate providing for the functions of 
environmental air quality assessment. Past modeling and emissions 
reductions measures have been submitted by the State and approved into 
the SIP. Additionally, Louisiana has the ability to perform modeling 
for primary and secondary NAAQS on a case by case permit basis 
consistent with their SIP-approved PSD rules and with EPA guidance.
    The La R.S. authorizes and requires LDEQ to cooperate with the 
federal government and local authorities concerning matters of common 
interest in the field of air quality control, thereby allowing the 
agency to make such submissions to the EPA.
    (L) Permitting Fees: The SIP must require each major stationary 
source to pay permitting fees to the permitting authority, as a 
condition of any permit required under the CAA, to cover the cost of 
reviewing and acting upon any application for such a permit, and, if 
the permit is issued, the costs of implementing and enforcing the terms 
of the permit. The fee requirement applies until a fee program 
established by the state pursuant to Title V of the CAA, relating to 
operating permits, is approved by EPA.
    The State has met this requirement as it has a fully developed fee 
system in place which is outlined in LAC:III Chapter 2 and is approved 
as part of the SIP. See element (E) above for the description of the 
mandatory collection of permitting fees outlined in the SIP.
    (M) Consultation/participation by affected local entities: The SIP 
must provide for consultation and participation by local political 
subdivisions affected by the SIP.
    See the discussion for element (J) above for a description of the 
SIP's public participation process, the authority to advise and 
consult, and the PSD SIP's public participation requirements. 
Additionally, the state noted that La R.S. 30: 2011(D)(21) also 
requires initiation of cooperative action between local authorities and 
the LDEQ, between one local authority and another, or among any 
combination of local authorities and the LDEQ for control of air 
pollution in areas having related air pollution problems that overlap 
the boundaries of political subdivisions, and entering into agreements 
and compacts with adjoining states and Indian tribes, where 
appropriate. The transportation conformity component of the Louisiana 
SIP requires that interagency consultation and opportunity for public 
involvement be provided before making transportation conformity 
determinations and before adopting applicable SIP revisions on 
transportation-related issues. (LAC 33:III1434)

Key to Table 1: Proposed action on LA infrastructure SIP submittals for various NAAQS
A--Approve
A*--Approved at an earlier date
+--Not germane to infrastructure SIPs
No action--EPA is taking no action on this infrastructure requirements
NA--Not applicable
D--Disapprove

    Based upon review of the state's infrastructure SIP submissions and 
relevant statutory and regulatory authorities and provisions referenced 
in these submissions or referenced in Louisiana's SIP, EPA believes 
that Louisiana has the infrastructure in place to address all 
applicable required elements of sections 110(a)(1) and (2) (except as 
noted in table above) to ensure that the 2006 PM2.5, 2008 
Pb, 2008 O3, 2010 NO2, 2010 SO2, and 
2012 PM2.5 NAAQS are implemented in the state.

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 
action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
     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 CAA; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    The SIP is not approved to apply on any Indian reservation land or 
in any other area where EPA or an Indian tribe has demonstrated that a 
tribe has jurisdiction. In those areas of Indian country, the proposed 
rule does not have tribal implications and will not impose substantial 
direct costs on tribal governments or preempt tribal law as specified 
by Executive Order 13175 (65 FR 67249, November 9, 2000).

List of Subjects in 40 CFR Part 52
