40 CFR Part 52

[EPA-R06-OAR-2014-0821; FRL-9945-10-Region 6]


Approval and Promulgation of Implementation Plans; Louisiana; 
Revisions to the New Source Review State Implementation Plan; Air 
Permit Procedure Revisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing 
approval of portions of ten revisions to the Louisiana New Source 
Review (NSR) State Implementation Plan (SIP) submitted by the Louisiana 
Department of Environmental Quality (LDEQ). These revisions to the 
Louisiana SIP provide updates to the minor NSR and nonattainment new 
source review (NNSR) permit programs in Louisiana contained within the 
Chapter 5 Permit Procedures and Chapter 6 Regulations on Control of 
Emissions through the Use of Emission Reduction Credits (ERC) Banking 
rules as initially submitted on November 15, 1993, and the subsequent 
rule amendments for Air Permit Procedure revisions submitted through 
November 3, 2014. The EPA's final action will incorporate these rules 
into the federally approved SIP. The rules generally enhance the SIP 
and were evaluated in accordance with CAA guidelines for the EPA action 
on SIP submittals and general rulemaking authority. This proposed 
action is consistent with the requirements of section 110 of the CAA.

I. Summary of State SIP Submittals for Chapter 5 and Chapter 6 Air 
Permit Program

    The EPA is proposing approval of the SIP revisions submitted by the 
State of Louisiana. The proposed revisions modify Louisiana's minor NSR 
and NNSR Chapters 5 Permit Procedure and Chapter 6 Regulations on 
Control of Emissions through the Use of Emission Reduction Credits 
(ERC) Banking rules enacted at Louisiana Administrative Code (LAC) 
33:III.501, 502, 503, 504, 511, 513.A.2., 513.A.3, 513.A.4., 513.A.5., 
513.A.6., 513.B., 513.C., 515, 517, 519.A., 519.B., 521, 523, 525, 527, 
529, 601, 603, 605, 607, 615, and 619. The revisions provide clarity to 
the rules, correct contradictory language, update permit application 
and fee requirements, revise the rules to conform to the latest 
Louisiana laws, and add to the ``Insignificant Activities List''.

A. November 15, 1993, Submittal

    On November 15, 1993, the LDEQ submitted revisions to the SIP. This 
SIP submittal incorporated revisions to the Louisiana Administrative 
Code (LAC) during the year 1993. It includes final revised regulation 
enacted at LAC 33:III, sections 501, 502, 503, 504, 505, 507, 511, 513, 
515, 517, 519, 521, 523, 525, 527, 529, and 533. The EPA is proposing 
to take action on sections 501, 502, 503, 511, 513, 515, 517, 519, 523, 
525, 527, and 529. The EPA already approved section 504 (NNSR 
Procedures) into the SIP on October 10, 1997, 62 FR 52948. The 504 
rules were then subsumed into later SIP approval revisions. The EPA 
returned sections 505, 507, and 533 due to their association with the 
Title V operating permit program requirements to the LDEQ on August 4, 
2015. The EPA is not taking action and severing section 513.A.1 (which 
references section 531), section 519.C. (which references section 531), 
and section 531 regarding public notice. Those specific sections will 
be addressed in a separate action. The EPA is not taking action and is 
severing section 501.B.1.d. at this time.

B. November 10, 1994, Submittal

    On November 10, 1994, the LDEQ submitted revisions to the SIP. This 
SIP submittal incorporated revisions to the LAC published in the 
Louisiana Register on November 20, 1994. It includes final revised 
regulations enacted at LAC 33:III, sections 501, 507, 517, 521, 527, 
and 533. The EPA is proposing to take action on sections 501, 517, 521, 
and 527. The EPA returned sections 507 and 533 due to their association 
with the title V operating permit program requirements to LDEQ on 
August 4, 2015.

C. July 25, 1997, Submittal

    On July 25, 1997, the LDEQ submitted the 1996 General revisions to 
the SIP. This SIP submittal incorporated revisions to LAC 33:III, 
sections 501, 504, 509, and 517 adopted during 1996. The EPA is 
proposing action on section 517. The EPA already approved sections 501, 
504 and 509 on November 5, 2015 (80 FR 68451). Section 504 was approved 
in 1997 as noted above and revisions have been subsumed into the SIP 
since the EPA's last action approving changes to the 504 rules on 
September 30, 2002 (67 FR 61260).

D. June 22, 1998, Submittal

    On June 22, 1998, the LDEQ submitted the 1997 General revisions to 
the SIP. This SIP submittal incorporated revisions to the LAC during 
the year 1997 and revisions to the LAC not previously federally 
approved. It includes final revised regulation at LAC 33:III, sections 
501, 509, and 517. The EPA is proposing action on sections 501 and 517. 
The EPA already approved section 509 on November 5, 2015 (80 FR 68451).

E. June 27, 2003, Submittal

    On June 27, 2003, the LDEQ submitted the 2002 General revisions to 
the SIP. This SIP submittal incorporated revisions to the LAC during 
the year 2002. It includes final revised regulation LAC 33:III, section 
501 covering the insignificant activities list. The EPA is proposing 
action on section 501.

F. May 5, 2006, Submittal

    On May 5, 2006, the LDEQ submitted the 2005 General revisions to 
the SIP. This SIP submittal incorporated revisions to the LAC during 
the year 2005 and revisions to the LAC not previously federally 
approved. It includes final revised regulation sections LAC 33:III.501, 
504, 505, 507, 509, 517, and 521. The EPA is proposing action on 
sections 501, 517, and 521. Since the last approval of section 504 in 
2002, the EPA approved changes to section 504 as well as section 509 on 
November 5, 2015 (80 FR 68451). The EPA returned to LDEQ sections 505 
and 507.C.3. due to their association with the title V operating permit 
program requirements on August 4, 2015. The EPA returned to LDEQ 
sections 507.H.4 and 507.H.5.d. due to their association with the title 
V operating permit program requirements on February 2, 2016.

G. November 9, 2007, Submittal

    On November 9, 2007, the LDEQ submitted the 2006 General revisions 
to the SIP. This SIP submittal incorporated revisions to the LAC during 
the year 2006 and revisions to the LAC not previously federally 
approved. It includes final revised regulation sections at LAC 
33:III.501, 504, 509,

[[Page 23234]]

513, 531, and 607. The EPA is proposing action on sections 513.A.2. and 
513.A.6. The EPA already approved sections 501, 504, 509, and 607 on 
November 5, 2015 (80 FR 68451). The EPA is not taking action and 
severing section 513.A.1. (which references section 531) and section 
531 regarding public notice. Those specific sections will be addressed 
in a separate action.

H. August 14, 2009, Submittal

    On August 14, 2009, the LDEQ submitted the 2007 General revisions 
to the SIP. This SIP submittal incorporated revisions to the LAC during 
the year 2007 and includes revisions to the LAC not previously 
federally approved. It includes final revised regulation sections LAC 
33:III.501, 504, 505, 506, and 507 contained in Chapter 5. It also 
includes final revised regulation sections LAC 33:III.603, 605, 607, 
613, and 615 contained in Chapter 6. The EPA is proposing action on 
section 501. The EPA already approved sections 504, 603, 605, 607, 613, 
and 615 on November 5, 2015 (80 FR 68451). The EPA already approved 
section 506 on April 17, 2014, (79 FR 21631). The EPA returned section 
505 to LDEQ on February 2, 2016, because it addresses the Acid Rain 
Program Permitting Requirements, which are implemented in the title V 
program rather than the SIP. The EPA returned section 507 to LDEQ on 
February 2, 2016, because it concerns the title V program which is not 
part of a SIP.

I. August 29, 2013, Submittal

    On August 29, 2013, the LDEQ submitted the 2008-2010 Volatile 
Organic Compounds Rule SIP Revision. This SIP submittal incorporated 
revisions to the LAC during the years 2008-2010 and includes revisions 
to final revised regulation section LAC 33:III.523. The EPA is 
proposing action on section 523.

J. November 3, 2014, Submittal

    On November 3, 2014, the LDEQ submitted the 2011-2013 Permit Rule 
revisions to the SIP. This SIP submittal incorporated revisions to the 
LAC during the years 2011-2012. It includes final revised regulation 
sections LAC 33:III.211, 223, 317, 319, 501, 502, 503, 504, 523, 537, 
601, 603, 605, 607, 615, 619, and 2132. The EPA is proposing action on 
sections 501, 502, 503, 504, 523, 601, 603, 605, 607, 615, and 619. The 
LDEQ withdrew sections 211 and 223 from SIP consideration by letter on 
December 2, 2015. The EPA is not acting on sections 317, 319, and 2132 
because this action only addresses Chapters 5 and 6. The EPA is not 
taking action on section 537 (AQ286) and revised citation 
501.B.2.d.i.(a) (AQ270) because the original 2008-2010 rule revision 
containing these sections was never submitted to the EPA. The EPA is 
not taking action and is severing section 501.B.1.d. at this time.
    Table 1 below summarizes the changes that are in the SIP revision 
submittals. A summary of the EPA's evaluation of each section and the 
basis for our proposed approval is included in this rulemaking. The 
accompanying Technical Support Document (TSD) includes a detailed 
evaluation of the submittals and our rationale. The TSD may be accessed 
online at www.regulations.gov, Docket No. EPA-R06-OAR-2014-0821.

II. Evaluation

A. Revisions to the NSR Air Permit Procedures

    We evaluated the SIP submissions and are proposing approval of the 
Louisiana Permit Procedures Revisions and ERC Banking Provisions, as 
identified, beginning with the November 15, 1993, through the November 
3, 2014, submissions. The Act at section 110(a)(2)(C) requires states 
to develop and submit to the EPA for approval into the SIP, 
preconstruction review programs applicable to new and modified 
stationary sources of air pollutants for attainment and nonattainment 
areas that cover both major and minor new sources and modifications, 
collectively referred to as the NSR SIP. The CAA NSR SIP program is 
composed of three separate programs: Prevention of Significant 
Deterioration (PSD), NNSR, and Minor NSR. PSD is established in part C 
of title I of the CAA and applies in areas that meet the National 
Ambient Air Quality Standards (NAAQS), i.e., ``attainment areas'', as 
well as areas where there is insufficient information to determine if 
the area meets the NAAQS, i.e., ``unclassifiable areas.'' The NNSR SIP 
program is established in part D of title I of the CAA and applies in 
areas that are not in attainment of the NAAQS, i.e., ``nonattainment 
areas.'' The Minor NSR SIP program addresses construction or 
modification activities that do not emit, or have the potential to 
emit, beyond certain major source thresholds and thus do not qualify as 
``major'' and applies regardless of the designation of the area in 
which a source is located. This particular SIP action will address the 
minor NSR and NNSR permitting programs.
    The EPA regulations governing the criteria that states must satisfy 
for the EPA approval of the NSR programs as part of the SIP are 
contained in 40 CFR 51.160-51.166. However, the PSD rules are not being 
evaluated in this action and therefore 40 CFR 51.166 does not provide a 
basis for a decision in this proposal. In addition, there are several 
provisions in 40 CFR part 51 that apply generally to all SIP revisions. 
As stated

[[Page 23235]]

above, 40 CFR 51.160 establishes the enforceable procedures that all 
NSR programs must include. 40 CFR 51.160-51.164 require that a SIP 
revision demonstrate that the adopted rules will not interfere with any 
applicable requirement concerning attainment and reasonable further 
progress, or any other applicable requirement of the CAA. Based upon 
our evaluation of the submittals, the EPA has concluded that the 
submittals as ultimately revised meet the requirements of the CAA 
section 110(a).
    Our evaluation found that May 20, 2012 and November 20, 2012 
adopted revisions to the NNSR program, submitted on November 3, 2014 
revised the program to address all nonattainment area pollutants and 
was necessary to ensure the Louisiana NNSR offset bank is able to be 
used in future instances where the State is designated nonattainment 
for other criteria pollutants. Prior to this action, the EPA proposed 
full approval of the major PSD and NNSR permitting program update, (80 
FR 50240), specifically those NNSR requirements submitted prior to 
November 3, 2014. That action was finalized on November 5, 2015 (80 FR 
68451).
    Our evaluation of the proposed minor NSR revisions found the 
proposed revisions address requirements that enhance the SIP. These 
changes (1) define insignificant activities that will not require 
permitting; (2) correct contradictory language in the insignificant 
activities list; (3) provide edits to the Permit Procedure Rule as 
requested by the EPA; (4) include procedures for incorporating test 
results; (5) unify and streamline name and ownership changes for all 
media; and (6) revise references to various LDEQ divisions. All of 
these changes will help to ensure that the LA Minor NSR rules to meet 
the CAA requirements.

B. Does the proposed approval of the Louisiana minor and nonattainment 
NSR Air Permit procedure revisions interfere with attainment, 
reasonable further progress, or any other applicable requirement of the 
Act?

    We have determined that the regulations submitted to the EPA for 
approval as SIP revisions meet the requirements of CAA section 110(l). 
The EPA's conclusion is based upon a line-by-line comparison of the 
proposed revisions with the federal requirements. The goal is to 
demonstrate that the proposed revisions will not interfere with the 
attainment of the NAAQS, Rate of Progress, RFP or any other applicable 
requirement of the CAA.
    The EPA prepared a CAA section 110(l) analysis in its review of the 
proposed list to serve as a basis for demonstrating noninterference for 
the affected pollutants for any applicable requirement for attainment 
and reasonable further progress such as: (1) Turning a maintenance area 
back into a nonattainment area; (2) turning an attainment/
unclassifiable area into a nonattainment area; (3) leading to a PSD 
increment exceedance; (4) causing the nonattainment area to have higher 
violations; or (5) causing a nonattainment area to have a greater 
number of NAAQS standard exceedances. This evaluation is contained in 
the individual tables for each regulatory section and is found in 
Section IV Conclusion of the TSD. The TSD can be found in the docket 
for this action. The comparison demonstrates that the changes made to 
the Louisiana rules reflect either the same regulatory language, or are 
consistent with the requirements found in the federal rules. Further, 
the Additional Comments to the table contained in section IV for the 
proposed revisions to section 501 in the TSD contain supporting 
technical documentation establishing in detail a CAA section 110(l) 
analysis regarding the tables of Insignificant Activities defined in 
section 501. Specifically, the Section 501.B.3, Insignificant 
Activities list, submitted on 5/5/2006, revised the former submittal 
11/10/1994, which was then subsumed by the 6/27/2003 submittal.
    Our finding is based in part on the historic trends of ambient air 
quality for the NAAQS pollutants, including ozone and sulfur dioxide 
(SO2), since those pollutants have caused past air quality 
issues.\1\ The EPA took into consideration the following factors when 
making the decision to propose approval into the SIP of the permit 
exemptions listed in the Insignificant Activities tables in section 
501:
---------------------------------------------------------------------------

    \1\ Supporting documentation is contained in the monitoring data 
of ambient air quality for NAAQS criteria for cities located 
throughout Louisiana. See http://www.deq.louisiana.gov/portal/DIVISIONS/Assessment/AirFieldServices/AmbientAirMonitoringProgram/AmbientAirMonitoringDataandReports.aspx.
---------------------------------------------------------------------------

     Compliance with the 8-hour ozone standard has improved 
state-wide with ozone pollutant concentrations trending downward with 
an average 23% decrease in ozone since the late 1980's. This average 
decrease represents air monitoring values in the Louisiana cities of 
Baton Rouge, Lake Charles, Monroe, New Orleans, and Point Coupee 
Parish. 8-Hour ozone trends are listed in the table below:

     The Baton Rouge marginal ozone nonattainment area is 
currently monitoring attainment for the 2008 ozone NAAQS. The 8-Hour 
ozone values have dropped from 83 ppb in 2006-2008 down to 71 ppb 
design value for 2015 in Baton Rouge.
     Compliance with the SO2 standard has improved 
significantly state-wide with SO2 pollutant concentrations 
trending downward with an average 55% decrease in SO2 since 
the mid 2000's. This average value represents the Louisiana air 
monitoring locations of Baton Rouge, Lake Charles, Chalmette, Port 
Allen, Shreveport, and Meraux. SO2 trends are listed in the 
table below:

     The EPA determined the St. Bernard 2010 SO2 
NAAQS nonattainment area was caused primarily by one large source of 
SO2 emissions, the Rain CII Carbon LLC--Chalmette Coke 
Plant. The LDEQ is currently preparing a proposed SIP attainment 
demonstration, ``St. Bernard Parish SO2 Nonattainment Area 
Louisiana SIP Revision,'' which was submitted to the EPA on April 1, 
2015, for review. The EPA provided comments and is working with the 
LDEQ to ensure the SIP revision contains the appropriate emission 
limits to bring the area into attainment status. The St. Bernard 
SO2 nonattainment area has documented SO2 
pollutant concentrations decreasing from a 331 ppm SO2 
design value in 2009 down to a 159 ppm SO2 design value in 
2014.
     Compliance with the Particulate Matter (PM10) 
standard is maintained and is below regulatory NAAQS levels. 
PM10 emission concentrations have trended downward an 
average 25% statewide since the mid 2000's. The average statewide 24-
hour PM10 concentration is 28 ug/m\3\ which is 19% of the 
NAAQS level for PM10. The average value represents the 
Louisiana air monitoring locations of Baton Rouge, New Orleans, 
Chalmette, Shreveport, and Lafayette.
     Compliance with the average statewide annual 
PM2.5 standards is maintained with an average annual maximum 
concentration of 10.8 ug/m\3\, which is below the average annual 
primary standard for PM2.5 of 12 ug/m\3\.
     The Baton Rouge Capitol air monitor is the only monitor 
collecting samples and analyzing for Carbon Monoxide (CO). The 2014 
annual average CO value was 0.26 ppm and the maximum monitored value 
was 5.34 ppm which is below the 9 ppm standard (8 hour averaging time).
    Since the list of exempted sources included in the proposed 
revisions have historically operated without coverage by an air permit 
and there are no anticipated increases in emissions or in the number of 
these type of sources resulting from the approval of the exempted list 
into the SIP, the EPA has determined the possibility of a low level of 
potential impacts on ambient air quality as a result of the emission 
sources and activities included in the proposed LAC 33:III section 501 
exemptions list and this conclusion is supported by ambient air 
monitoring trends in the State of Louisiana.
    Our determination is consistent with our assessment of the 
environmental insignificance of these emissions. In addition, the LDEQ 
has been carrying out the minor NSR air permitting program based on the 
codification of their permitting policy without any indication that 
these permit exempted sources have interfered with attainment or 
reasonable further progress or increased PSD increment. Therefore, the 
EPA proposes to approve the exemptions lists in section 501 into the 
Louisiana SIP.
    Based on supporting air quality monitoring data documenting air 
quality improvements throughout the State, the EPA proposes to approve 
Section 501 containing the list of the exempted sources into the 
Louisiana SIP since it meets the requirements of CAA section 110(l) and 
since state agencies are provided the latitude to define the types and 
sizes of facilities, buildings, structures, or installations subject to 
review in accordance with 40 CFR 51.160(e). We believe the 
implementation of this rule will not interfere with any applicable 
requirement concerning attainment and reasonable further progress, 
maintaining PSD increment, or any other applicable requirement of the 
CAA.

III. Proposed Action

    The EPA proposes approval of the identified sections of the 
revisions to the air permitting procedures as submitted as revisions to 
the Louisiana NSR SIP Permit program on November 15, 1993, November 10, 
1994, July 25, 1997, June 22, 1998, June 27, 2003, May 5, 2006, 
November 9, 2007, August 14, 2009, August 29, 2013, and November 3, 
2014, submittals. The EPA has made the determination in accordance with 
the CAA and the EPA regulations at 40 CFR 51.160-51.165. Therefore, 
under section 110 and part C of the Act, and for the reasons presented 
above and in our accompanying TSD, the EPA proposes approval of the 
revisions to the Louisiana SIP identified in Table 2 below which 
summarizes each regulatory citation that is affected by this action.

IV. Incorporation by Reference

    In this action, we are proposing to include in a final rule 
regulatory text that includes incorporation by reference. In accordance 
with the requirements of 1 CFR 51.5, we are proposing to incorporate by 
reference revisions to the Louisiana regulations as described in the 
Proposed Action section above. We have made, and will continue to make, 
these documents generally available electronically through 
www.regulations.gov and/or in hard copy at the EPA Region 6 office.

V. Statutory and Executive Order Reviews

    Under the CAA, 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, the EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. 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

[[Page 23239]]

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).
    In addition, 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).
