SUMMARY: EPA is approving revisions to
the Louisiana State Implementation
Plan (SIP) concerning the 8-hour ozone
maintenance plans for the parishes of
Lafayette and Lafourche. On October 13,
2006 and December 19, 2006, the State
of Louisiana submitted maintenance
plans for Lafayette and Lafourche
Parishes, respectively, which ensure
continued attainment of the 8-hour
ozone National Ambient Air Quality
Standard (NAAQS) through the year
2014. These maintenance plans meet the
statutory and regulatory requirements,
and are consistent with EPA’s guidance.
EPA is approving the revisions pursuant
to section 110 of the Federal Clean Air
Act (CAA).
DATES: This rule is effective on May 23,
2008 without further notice, unless EPA

IV. Statutory and Executive Order Reviews
I. Background
Under section 107 of the 1977 CAA,
Louisiana’s Lafayette and Lafourche
Parishes were designated as
nonattainment areas because they did
not meet the National Ambient Air
Quality Standards (NAAQS) for 1-hour
ozone (40 CFR 81.319). As required by
section 110 of the CAA, the state of
Louisiana submitted a SIP to EPA on
December 10, 1979. EPA approved this
SIP on October 29, 1981 (46 FR 53412).
Under the 1990 CAA Amendments, the
E:\FR\FM\24MRR1.SGM
24MRR1
pwalker on PROD1PC71 with RULES
15412
Federal Register / Vol. 73, No. 57 / Monday, March 24, 2008 / Rules and Regulations
Lafayette and Lafourche Parish
nonattainment areas continued to be
designated nonattainment for the 1-hour
ozone NAAQS by operation of law since
Louisiana had not yet collected the
required three years of data necessary to
petition for redesignation to attainment.
On May 25, 1993 and November 18,
1994, Louisiana submitted requests to
redesignate Lafayette and Lafourche
Parishes, respectively, to attainment for
the 1-hour ozone standard. At the same
time, the State submitted the required
ozone monitoring data and maintenance
plans for each parish (each area
includes only the one Parish) to ensure
the areas would remain in attainment
for 1-hour ozone for a period of 10
years. The maintenance plans submitted
by Louisiana followed EPA guidance for
limited maintenance areas, which
provides for 1-hour ozone areas that
have design values less than 85% of the
applicable standard. In this case, the
applicable standard was the 1-hour
ozone standard of 0.12 parts per million
(ppm). At the time of the redesignation
request, the design values for Lafayette
and Lafourche Parishes were 0.102 ppm
and 0.098 ppm, respectively, and below
the 85% threshold of 0.106 ppm.
Due to several approvability issues
that existed with the Lafayette Parish
maintenance plan and redesignation
request, the state submitted a revised
maintenance plan and redesignation
request to EPA on October 14, 1994.
EPA approved Louisiana’s request to
redesignate Lafayette Parish to
attainment for the 1-hour ozone
standard and approved the Parish’s
maintenance plan on August 18, 1995
(60 FR 43020), with an effective date of
October 17, 1995.
EPA originally approved Louisiana’s
request to redesignate Lafourche Parish
to attainment for the 1-hour ozone
standard and approved the Parish’s
maintenance plan on August 18, 1995
(60 FR 43020). However, before the
redesignation to attainment was
effective, a violation of the 1-hour ozone
standard was recorded at a Lafourche
Parish ozone monitoring station. On
December 5, 1997, EPA corrected the
designation for Lafourche Parish to
nonattainment for the 1-hour ozone
standard (62 FR 64284) but left the
Parish’s maintenance plan approved on
August 18, 1995 in place. On August 9,
2000, the Louisiana Department of
Environmental Quality (LDEQ) again
requested to redesignate Lafourche
Parish to attainment for the 1-hour
ozone standard by submitting data
indicating the 1-hour ozone standard
had been achieved for the period of
January 1, 1997 through December 31,
1999. EPA also evaluated the ozone data
VerDate Aug<31>2005
16:13 Mar 21, 2008
Jkt 214001
from the years 2000 and 2001, and no
violations of the 0.12 ppm 1-hour ozone
standard occurred in these additional
years. Since the data satisfied the
regulatory requirements of no more than
one exceedance per annual monitoring
period, EPA approved Louisiana’s
request to redesignate Lafourche Parish
to attainment on December 26, 2001 (66
FR 66317), with an effective date of
February 25, 2002.
On April 30, 2004, EPA designated
and classified areas for the new 8-hour
ozone NAAQS (69 FR 23858), and
published the final phase 1 rule for
implementation of the 8-hour ozone
NAAQS (69 FR 23951). Lafayette and
Lafourche Parishes were designated as
unclassifiable/attainment for the 8-hour
ozone standard, effective June 15, 2004.
The two attainment areas consequently
were required to submit a 10-year
maintenance plan under section
110(a)(1) of the CAA and the Phase 1
rule. On May 20, 2005, EPA issued
guidance providing information
regarding how a state might fulfill the
maintenance plan obligation established
by the Act and the Rule (Memorandum
from Lydia N. Wegman to Air Division
Directors, Maintenance Plan Guidance
Document for Certain 8-Hour Ozone
Areas Under Section 110(a)(1) of Clean
Air Act, May 20, 2005). These SIP
revisions satisfy the section 110(a)(1)
CAA requirements for a plan that
provides for implementation,
maintenance, and enforcement of the 8hour ozone NAAQS in the Lafayette and
Lafourche Parish 8-hour ozone
unclassifiable/attainment areas.
On December 22, 2006, the United
States Court of Appeals for the District
of Columbia Circuit issued an opinion
that vacated EPA’s Phase 1
Implementation Rule for the 8-hour
Ozone Standard. (South Coast Air
Quality Management District. v. EPA,
472 F.3d 882 (D.C.Cir. 2006)). Petitions
for rehearing were filed with the Court,
and on June 8, 2007, the Court modified
the scope of the vacatur of the Phase 1
rule. The Court vacated those portions
of the Rule that provide for regulation
of 8-hour ozone nonattainment areas
under Subpart 1 in lieu of Subpart 2 and
that allow backsliding with respect to
new source review, penalties,
milestones, contingency plans, and
motor vehicle emission budgets.
Consequently, the Court’s modified
ruling does not alter any requirements
under the Phase 1 8-hour ozone
implementation rule for maintenance
plans.
II. Analysis of the State’s Submittals
On October 13, 2006 and December
19, 2006, the State of Louisiana
PO 00000
Frm 00026
Fmt 4700
Sfmt 4700
submitted maintenance plans for the
Parishes of Lafayette and Lafourche,
respectively. These October and
December revisions provide 8-hour
ozone maintenance plans for the two
parishes named above, as required by
section 110(a)(1) of the CAA and the
provisions of EPA’s Phase 1
Implementation Rule (see 40 CFR
51.905(a)(4)). The purpose of these
plans is to ensure continued attainment
and maintenance of the NAAQS for 8hour ozone in Lafayette and Lafourche
Parishes.
In this action, EPA is approving the
State’s 8-hour ozone maintenance plans
for the Lafayette and Lafourche Parish
areas because EPA finds that the LDEQ
submittals meet the requirements of
section 110(a)(1) of the CAA, EPA’s rule,
and is consistent with EPA’s guidance.
As required, these plans provide for
continued attainment and maintenance
of the 8-hour ozone NAAQS in these
areas for 10 years from the effective date
of the area’s designation as
unclassifiable/attainment for the 8-hour
ozone NAAQS, and include components
illustrating how each Parish will
continue in attainment of the 8-hour
ozone NAAQS and contingency
measures. Each of the section 110(a)(1)
plan components is discussed below.
(a) Attainment Inventory. The LDEQ
developed comprehensive inventories of
volatile organic compound (VOC) and
nitrogen oxide (NOX) emissions from
area, stationary, and mobile sources
using 2002 as the base year to
demonstrate maintenance of the 8-hour
ozone NAAQS for Lafayette and
Lafourche Parishes. The year 2002 is an
appropriate year for the LDEQ to base
attainment level emissions because
States may select any one of the three
years on which the 8-hour attainment
designation was based (2001, 2002, and
2003). The State’s submittals contain the
detailed inventory data and summaries
by source category. The 2002 base year
inventory is a good choice. Using the
2002 inventory as a base year reflects
one of the years used for calculating the
air quality design values on which the
8-hour ozone designation decisions
were based. It also is one of the years
in the 2002–2004 period used to
establish baseline visibility levels for
the regional haze program.
A practical reason for selecting 2002
as the base year emission inventory is
that Section 110(a)(2)(B) of the CAA and
the Consolidated Emissions Reporting
Rule (67 FR 39602, June 10, 2002)
require States to submit emissions
inventories for all criteria pollutants and
their precursors every three years, on a
schedule that includes the emissions
year 2002. The due date for the 2002
E:\FR\FM\24MRR1.SGM
24MRR1
Federal Register / Vol. 73, No. 57 / Monday, March 24, 2008 / Rules and Regulations
emissions inventory was established in
the rule as June 2004. In accordance
with these requirements, the State of
Louisiana compiles a statewide
emissions inventory for point sources
on an annual basis. For stationary point
sources in Lafayette and Lafourche
Parishes, the LDEQ provided estimates
for each commercial or industrial
operation that emits 100 tons or more
per year of VOC or 100 tons or more per
year of NOX in Appendix A of each
maintenance plan. Stationary non-point
source data was provided by E.H.
Pechan & Associates, Inc., through the
Central Regional Air Planning
Association (CENRAP) using the
methodology in ‘‘Consolidation of
Emissions Inventories’’, section C, page
26. On-road mobile emissions of VOC
and NOX were estimated using EPA’s
MOBILE6.2 motor vehicle emissions
factor computer model. Non-road
mobile emissions data were derived
from the ‘‘Emission Inventory
Development For Mobile Sources and
Agricultural Dust Sources for the
Central States’’ produced by Sonoma
Technology, Inc. for CENRAP in
October 2004 using EPA’s NONROAD
2004 non-road mobile emissions
computer model. EPA finds that the
LDEQ prepared the 2002 base year
emissions inventories for the two
Parishes consistent with EPA’s longestablished guidance memoranda.
In projecting data for the attainment
year 2014 inventory, LDEQ used several
methods to project data from the base
year 2002 to the years 2008, 2011, and
15413
2014. These projected inventories were
developed using EPA-approved
technologies and methodologies. Point
source and non-point source projections
were derived from the Emissions
Growth Analysis System version 4.0
(EGAS 4.0). Non-road mobile
projections were derived from EGAS
4.0, as well as from the National Mobile
Inventory Model.
The following tables provide VOC and
NOX emissions data for the 2002 base
attainment year inventory, as well as
projected VOC and NOX emission
inventory data for the years 2008, 2011,
and 2014. Please see the Technical
Support Document (TSD) for additional
emissions inventory data including
projections by source category for each
parish.

review of the State’s methodologies,
modeling data and performance, etc. for
developing the base and attainment year
inventories. As shown in the tables
above, the State has demonstrated that
the future year 8-hour ozone emissions
will be less than the 2002 base
attainment year’s emissions. The
attainment inventories submitted by the
LDEQ for these areas are consistent with
the criteria as discussed in the EPA
Maintenance Plan Guidance memo
dated May 20, 2005. EPA finds that the
future emissions levels in 2008, 2011
and 2014 for total VOC and total NOX
are expected to be less than the
emissions levels in 2002.

(b) Maintenance Demonstration. The
primary purpose of a maintenance plan
is to demonstrate how an area will
continue to remain in compliance with
the 8-hour ozone standard for the 10year period following the effective date
of designation as unclassifiable/
attainment. The end projection year is
10 years from the effective date of the
attainment designation, which for
Lafayette and Lafourche Parishes was
June 15, 2004. Therefore, these plans
must demonstrate attainment through
2014. As discussed in section (a)
Attainment Inventory above, Louisiana
has identified the level of ozone-forming
emissions in Lafayette and Lafourche
Parishes that were consistent with
attainment of the NAAQS for ozone in
2002. Louisiana has projected VOC and
NOX emissions for the years 2008, 2011,
and 2014 in Lafayette and Lafourche
Parishes and EPA finds that the future
emissions levels for total VOC and total

Please see the TSD for more information
on EPA’s review and evaluation of the
State’s 2008, 2011, and 2014 projected
emissions inventories.
Louisiana relies on several air quality
measures that will provide for
additional 8-hour ozone emissions
reductions in Lafayette and Lafourche
Parishes. These measures include the
following, among others: (1)
Implementation of EPA’s National Rule
for VOC Emission Standards for
Automobile Refinish Coatings (63 FR
48806), Consumer Products (63 FR
48819), and Architectural Coatings (63
FR 48848), (2) enacting of specific
requirements from EPA’s Tier 2 Motor
Vehicle Emission Standards (65 FR
6697), EPA’s Heavy-Duty Engine and
Vehicle Standards (66 FR 5002), as well
as EPA’s gasoline and highway diesel
fuel sulfur control requirements (66 FR
E:\FR\FM\24MRR1.SGM
24MRR1
pwalker on PROD1PC71 with RULES
15414
Federal Register / Vol. 73, No. 57 / Monday, March 24, 2008 / Rules and Regulations
5002), (3) EPA’s required control of
emissions from non-road diesel engines
and fuels (69 FR 38958), and (4)
implementation of the Federal Clean Air
Interstate Rule (CAIR) (70 FR 25162).
The purpose of these control measures
is to reduce levels of 8-hour ozone,
including the areas of Lafayette and
Lafourche Parishes.
As an additional demonstration of
maintenance, Louisiana references the
EPA modeling conducted for CAIR, in
the maintenance plan submittals.
Louisiana is a state that must implement
CAIR, and the EPA CAIR modeling
indicates that all Louisiana parishes will
be in attainment with the 8-hour ozone
standard by 2010, with continued
attainment projected through 2015. This
analysis is consistent with the
projections discussed above in (a)
Attainment Inventory.
(c) Ambient Air Quality Monitoring.
The State of Louisiana has committed in
its maintenance plans for Lafayette and
Lafourche Parishes to continue
operation of an appropriate, EPAapproved, ozone monitoring network
and to work with EPA in compliance
with 40 CFR Part 58 with regard to the
continued adequacy of the network, if
additional monitoring is needed, and
when monitoring can be discontinued.
The 8-hour ozone NAAQS is 0.08 ppm
based on the three-year average of the
fourth-highest daily maximum 8-hour
average ozone concentration measured
at each monitor within an area. The
standard is considered to be attained at
84 parts per billion (ppb).
The Lafayette monitoring site has
monitored attainment with the 8-hour
ozone standard since 1998. The three
most recent 8-hour ozone design values
at the time of the October 2006
submission of the maintenance plan for
Lafayette Parish were 78 ppb for 2003,
79 ppb for 2004, and 82 ppb for 2005.
Due to issues with the lease agreement
at the monitoring site location, the
Lafayette monitoring site location was
relocated to its current location on the
campus of Louisiana State University.
Sampling started at the current location
on December 12, 2005, for the beginning
of the 2006 ozone season. (The ozone
season in the State of Louisiana is from
January to December for the Parishes
discussed in this notice.) Since the 8hour ozone design value is based on a
three-year average of the fourth-highest
daily maximum 8-hour average ozone
concentration, the first available design
value for the current monitoring
location will be available once three
ozone monitoring seasons (2006, 2007
and 2008) have been completed.
According to the most recent data
available in EPA’s Air Quality System
VerDate Aug<31>2005
16:13 Mar 21, 2008
Jkt 214001
(AQS) for the current Lafayette
monitoring site, the annual fourth
highest daily maximum values are 84
ppb for 2006 and 73 ppb for 2007 based
on preliminary data from the January
2007 through September 2007
timeframe. Based on the NAAQS
standard discussed above, each of the
design values for Lafayette Parish is
considered to be in attainment of the 8hour ozone NAAQS and demonstrates
that Lafayette Parish is expected to
continue attainment of the 8-hour ozone
NAAQS.
The Lafourche monitoring site, which
was relocated at the end of 1999 to its
current location, has monitored
attainment with the 8-hour ozone
standard since 2001. The three most
recent 8-hour ozone design values at the
time of December 2006 submission of
the maintenance plan for Lafourche
Parish were 78 ppb for 2003, 76 ppb for
2004, and 79 ppb for 2005. Based upon
the most recent data available in AQS
for the Lafourche monitoring site, the
design value for 2006 was 80 ppb and
a preliminary design value for 2007 is
79 ppb based on data from the January
2007 through September 2007
timeframe. Based on the NAAQS
standard discussed above, each of these
design values for Lafourche Parish is
considered to be in attainment of the 8hour NAAQS and further demonstrates
that Lafourche Parish is expected to
continue attainment of the 8-hour ozone
NAAQS.
(d) Contingency Plan. The section
110(a)(1) maintenance plans include
contingency provisions to promptly
correct any violation of the NAAQS that
occurs. The contingency indicator for
the Lafayette and Lafourche Parish
maintenance plans is based upon
monitoring. The triggering mechanism
for activation of contingency measures
is a monitoring violation of the 8-hour
ozone standard and analysis of data to
determine the cause of the violation. In
these maintenance plans, if contingency
measures are triggered, LDEQ is
committing to implement the measures
as expeditiously as practicable, but no
longer than 24 months following the
trigger.
The following contingency measures
are identified for implementation: (1)
Lowering VOC RACT applicability
thresholds for Stage 1 gasoline controls,
(2) NOX controls on major sources (100
tpy and greater), (3) Emission offsets for
permits (1.10 ratio for VOC and NOX),
and (4) Other measures deemed
appropriate at the time as a result of
advances in control technologies. These
contingency measures and schedules for
implementation satisfy EPA’s longstanding guidance on the requirements
PO 00000
Frm 00028
Fmt 4700
Sfmt 4700
of section 110(a)(1) for continued
attainment. Continued attainment of the
8-hour ozone NAAQS in the areas of
Lafayette and Lafourche Parishes will
depend, in part, on the air quality
measures discussed previously (see II
(b) above). The State will continue to
operate an appropriate, EPA-approved,
ambient ozone monitoring site in
Lafayette and Lafourche Parish to verify
continued attainment of the 8-hour
ozone NAAQS. The air monitoring
results will reveal changes in the
ambient air quality as well as assist the
State in determining whether or not
implementation of any contingency
measures is necessary. The state will
continue to work with the EPA through
the air monitoring network review
process, as required by 40 CFR Part 58,
to determine: (1) The adequacy of the
ozone monitoring network; (2) if
additional monitoring is needed; and (3)
when monitoring can be discontinued.
Air monitoring data will continue to be
quality assured according to federal
requirements.
III. Final Action
Pursuant to section 110 of the Act,
EPA is approving the 8-hour ozone
maintenance plans for Lafayette and
Lafourche Parishes, which were
submitted by LDEQ on October 13,
2006, and December 19, 2006,
respectively, which ensure continued
attainment of the 8-hour ozone NAAQS
through the year 2014. We have
evaluated the State’s submittals and
have determined that they meet the
applicable requirements of the Clean Air
Act and EPA regulations, and are
consistent with EPA policy.
EPA is publishing this rule without
prior proposal because we view this as
a non-controversial amendment and
anticipate no adverse comments.
However, in the proposed rules section
of this Federal Register publication, we
are publishing a separate document that
will serve as the proposal to approve the
SIP revision if relevant adverse
comments are received. This rule will
be effective on May 23, 2008, without
further notice unless we receive adverse
comment by April 23, 2008. If we
receive adverse comments, we will
publish a timely withdrawal in the
Federal Register informing the public
that the rule will not take effect. We will
address all public comments in a
subsequent final rule based on the
proposed rule. We will not institute a
second comment period on this action.
Any parties interested in commenting
must do so now. Please note that if we
receive adverse comment on an
amendment, paragraph, or section of
this rule and if that provision may be
E:\FR\FM\24MRR1.SGM
24MRR1
15415
Federal Register / Vol. 73, No. 57 / Monday, March 24, 2008 / Rules and Regulations
severed from the remainder of the rule,
we may adopt as final those provisions
of the rule that are not the subject of an
adverse comment.
IV. Statutory and Executive Order
Reviews
Under Executive Order 12866 (58 FR
51735, October 4, 1993), this action is
not a ‘‘significant regulatory action’’ and
therefore is not subject to review by the
Office of Management and Budget. For
this reason, this action is also not
subject to Executive Order 13211,
‘‘Actions Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use’’ (66 FR 28355, May
22, 2001). This action merely approves
state law as meeting Federal
requirements and imposes no additional
requirements beyond those imposed by
state law. Accordingly, the
Administrator certifies that this rule
will not have a significant economic
impact on a substantial number of small
entities under the Regulatory Flexibility
Act (5 U.S.C. 601 et seq.). Because this
rule approves pre-existing requirements
under state law and does not impose
any additional enforceable duty beyond
that required by state law, it does not
contain any unfunded mandate or
significantly or uniquely affect small
governments, as described in the
Unfunded Mandates Reform Act of 1995
(Pub. L. 104–4).
This rule also does not have tribal
implications because it will not have a
substantial direct effect on one or more
Indian tribes, on the relationship
between the Federal Government and
Indian tribes, or on the distribution of
power and responsibilities between the
Federal Government and Indian tribes,
as specified by Executive Order 13175
(65 FR 67249, November 9, 2000). This
action also does not have Federalism
implications because it does not have
substantial direct effects on the States,
on the relationship between the national
government and the States, or on the
distribution of power and
responsibilities among the various
levels of government, as specified in
Executive Order 13132 (64 FR 43255,
August 10, 1999). This action merely
approves a state rule implementing a
Federal standard, and does not alter the
relationship or the distribution of power
and responsibilities established in the
CAA. This rule also is not subject to
Executive Order 13045 ‘‘Protection of
Children from Environmental Health
Risks and Safety Risks’’ (62 FR 19885,
April 23, 1997), because it is not
economically significant.
In reviewing SIP submissions, EPA’s
role is to approve state choices,
provided that they meet the criteria of
the Clean Air Act. In this context, in the
absence of a prior existing requirement
for the State to use voluntary consensus
standards (VCS), EPA has no authority
to disapprove a SIP submission for
failure to use VCS. It would thus be
inconsistent with applicable law for
EPA, when it reviews a SIP submission,
to use VCS in place of a SIP submission
that otherwise satisfies the provisions of
the CAA. Thus, the requirements of
section 12(d) of the National
Technology Transfer and Advancement
Act of 1995 (15 U.S.C. 272 note) do not
apply. This rule does not impose an
information collection burden under the
provisions of the Paperwork Reduction
Act of 1995 (44 U.S.C. 3501 et seq.).
The Congressional Review Act, 5
U.S.C. 801 et seq., as added by the Small
Business Regulatory Enforcement
Fairness Act of 1996, generally provides
that before a rule may take effect, the
agency promulgating the rule must
submit a rule report, which includes a
copy of the rule, to each House of the
Congress and to the Comptroller General
of the United States. EPA will submit a
report containing this rule and other
required information to the U.S. Senate,
the U.S. House of Representatives, and
the Comptroller General of the United
States prior to publication of the rule in
the Federal Register. A major rule
cannot take effect until 60 days after it
is published in the Federal Register.
This action is not a ‘‘major rule’’ as
defined by 5 U.S.C. 804(2).
Under section 307(b)(1) of the CAA,
petitions for judicial review of this
action must be filed in the United States
Court of Appeals for the appropriate
circuit by May 23, 2008. Filing a
petition for reconsideration by the
Administrator of this final rule does not
affect the finality of this rule for the
purposes of judicial review nor does it
extend the time within which a petition
for judicial review may be filed, and
shall not postpone the effectiveness of
such rule or action. This action may not
be challenged later in proceedings to
enforce its requirements. (See section
307(b)(2).)

(i) Approval. The Louisiana
Department of Environmental Quality
(LDEQ) submitted 8-hour ozone
maintenance plans for the Lafayette and
Lafourche Parish areas on October 13,
2006 and December 19, 2006,
respectively. The two areas are
designated unclassifiable/attainment for
the 8-hour ozone standard. EPA
determined these requests for Lafayette
and Lafourche Parishes were complete
on November 30, 2006 and May 2, 2007,
respectively. These maintenance plans
meet the requirements of section
110(a)(1) of the Clean Air Act, and are
consistent with EPA’s maintenance plan
guidance document dated May 20, 2005.
The EPA therefore approved the 8-hour
ozone maintenance plans for the
Lafayette and Lafourche Parish areas on
March 24, 2008.

40 CFR Part 52
Finding of Failure To Submit State
Implementation Plans Required for the
1997 8-Hour Ozone NAAQS
Environmental Protection
Agency (EPA).
ACTION: Final Rule.
AGENCY:
SUMMARY: The EPA is taking a final
action finding that several states have
failed to submit State Implementation
Plans (SIPs) to satisfy certain
requirements of the Clean Air Act (CAA)
for the 1997 8-hour ozone National
Ambient Air Quality Standards
(NAAQS). Under the CAA and EPA’s
implementing regulations, states with
nonattainment areas classified as
moderate, serious, severe or extreme
were required to submit by June 15,
2007, SIPs: Demonstrating how each
nonattainment area would attain the
1997 8-hour ozone standard as
expeditiously as practicable but no later
than the applicable dates established in
the implementing regulations; and
demonstrating reasonable further
progress (RFP). Additionally, states
were required by September 15, 2006, to
submit for these same areas SIPs
demonstrating that sources specified
under the CAA were subject to
reasonably available control technology
requirements (RACT). States that are
part of the Ozone Transport Region
(OTR) were required to submit SIPs to
meet the 1997 8-hour ozone RACT
requirement for the entire state by
September 15, 2006. The RACT
requirement applies to all areas within
the Ozone Transport Region, regardless
of the area’s designation for the 1997
8-hour ozone standard. Some states
have not yet submitted SIPs to satisfy
these requirements. The EPA is by this
action making a finding of failure to
submit for those nonattainment areas
and OTR areas that have not made the
required SIP submission(s). If EPA has
not affirmatively found that the state has
submitted the required plan or plans
within 18 months, the offset sanction
applies in the area. If within 6
additional months EPA has still not
affirmatively determined that the state
has submitted the required plan, the
highway funding sanction applies in an
area if it is designated nonattainment.
No later than 2 years after EPA makes
the finding, EPA must promulgate a
Federal Implementation Plan if the state
has not submitted and EPA has not
approved the required SIP.
DATES: Effective Date: This action is
effective on March 24, 2008.

I. Background
Under section 107 of the 1977 CAA, Louisiana's Lafayette and
Lafourche Parishes were designated as nonattainment areas because they
did not meet the National Ambient Air Quality Standards (NAAQS) for 1-
hour ozone (40 CFR 81.319). As required by section 110 of the CAA, the
state of Louisiana submitted a SIP to EPA on December 10, 1979. EPA
approved this SIP on October 29, 1981 (46 FR 53412). Under the 1990 CAA
Amendments, the
[[Page 15412]]
Lafayette and Lafourche Parish nonattainment areas continued to be
designated nonattainment for the 1-hour ozone NAAQS by operation of law
since Louisiana had not yet collected the required three years of data
necessary to petition for redesignation to attainment.
On May 25, 1993 and November 18, 1994, Louisiana submitted requests
to redesignate Lafayette and Lafourche Parishes, respectively, to
attainment for the 1-hour ozone standard. At the same time, the State
submitted the required ozone monitoring data and maintenance plans for
each parish (each area includes only the one Parish) to ensure the
areas would remain in attainment for 1-hour ozone for a period of 10
years. The maintenance plans submitted by Louisiana followed EPA
guidance for limited maintenance areas, which provides for 1-hour ozone
areas that have design values less than 85% of the applicable standard.
In this case, the applicable standard was the 1-hour ozone standard of
0.12 parts per million (ppm). At the time of the redesignation request,
the design values for Lafayette and Lafourche Parishes were 0.102 ppm
and 0.098 ppm, respectively, and below the 85% threshold of 0.106 ppm.
Due to several approvability issues that existed with the Lafayette
Parish maintenance plan and redesignation request, the state submitted
a revised maintenance plan and redesignation request to EPA on October
14, 1994. EPA approved Louisiana's request to redesignate Lafayette
Parish to attainment for the 1-hour ozone standard and approved the
Parish's maintenance plan on August 18, 1995 (60 FR 43020), with an
effective date of October 17, 1995.
EPA originally approved Louisiana's request to redesignate
Lafourche Parish to attainment for the 1-hour ozone standard and
approved the Parish's maintenance plan on August 18, 1995 (60 FR
43020). However, before the redesignation to attainment was effective,
a violation of the 1-hour ozone standard was recorded at a Lafourche
Parish ozone monitoring station. On December 5, 1997, EPA corrected the
designation for Lafourche Parish to nonattainment for the 1-hour ozone
standard (62 FR 64284) but left the Parish's maintenance plan approved
on August 18, 1995 in place. On August 9, 2000, the Louisiana
Department of Environmental Quality (LDEQ) again requested to
redesignate Lafourche Parish to attainment for the 1-hour ozone
standard by submitting data indicating the 1-hour ozone standard had
been achieved for the period of January 1, 1997 through December 31,
1999. EPA also evaluated the ozone data from the years 2000 and 2001,
and no violations of the 0.12 ppm 1-hour ozone standard occurred in
these additional years. Since the data satisfied the regulatory
requirements of no more than one exceedance per annual monitoring
period, EPA approved Louisiana's request to redesignate Lafourche
Parish to attainment on December 26, 2001 (66 FR 66317), with an
effective date of February 25, 2002.
On April 30, 2004, EPA designated and classified areas for the new
8-hour ozone NAAQS (69 FR 23858), and published the final phase 1 rule
for implementation of the 8-hour ozone NAAQS (69 FR 23951). Lafayette
and Lafourche Parishes were designated as unclassifiable/attainment for
the 8-hour ozone standard, effective June 15, 2004. The two attainment
areas consequently were required to submit a 10-year maintenance plan
under section 110(a)(1) of the CAA and the Phase 1 rule. On May 20,
2005, EPA issued guidance providing information regarding how a state
might fulfill the maintenance plan obligation established by the Act
and the Rule (Memorandum from Lydia N. Wegman to Air Division
Directors, Maintenance Plan Guidance Document for Certain 8-Hour Ozone
Areas Under Section 110(a)(1) of Clean Air Act, May 20, 2005). These
SIP revisions satisfy the section 110(a)(1) CAA requirements for a plan
that provides for implementation, maintenance, and enforcement of the
8-hour ozone NAAQS in the Lafayette and Lafourche Parish 8-hour ozone
unclassifiable/attainment areas.
On December 22, 2006, the United States Court of Appeals for the
District of Columbia Circuit issued an opinion that vacated EPA's Phase
1 Implementation Rule for the 8-hour Ozone Standard. (South Coast Air
Quality Management District. v. EPA, 472 F.3d 882 (D.C.Cir. 2006)).
Petitions for rehearing were filed with the Court, and on June 8, 2007,
the Court modified the scope of the vacatur of the Phase 1 rule. The
Court vacated those portions of the Rule that provide for regulation of
8-hour ozone nonattainment areas under Subpart 1 in lieu of Subpart 2
and that allow backsliding with respect to new source review,
penalties, milestones, contingency plans, and motor vehicle emission
budgets. Consequently, the Court's modified ruling does not alter any
requirements under the Phase 1 8-hour ozone implementation rule for
maintenance plans.
II. Analysis of the State's Submittals
On October 13, 2006 and December 19, 2006, the State of Louisiana
submitted maintenance plans for the Parishes of Lafayette and
Lafourche, respectively. These October and December revisions provide
8-hour ozone maintenance plans for the two parishes named above, as
required by section 110(a)(1) of the CAA and the provisions of EPA's
Phase 1 Implementation Rule (see 40 CFR 51.905(a)(4)). The purpose of
these plans is to ensure continued attainment and maintenance of the
NAAQS for 8-hour ozone in Lafayette and Lafourche Parishes.
In this action, EPA is approving the State's 8-hour ozone
maintenance plans for the Lafayette and Lafourche Parish areas because
EPA finds that the LDEQ submittals meet the requirements of section
110(a)(1) of the CAA, EPA's rule, and is consistent with EPA's
guidance. As required, these plans provide for continued attainment and
maintenance of the 8-hour ozone NAAQS in these areas for 10 years from
the effective date of the area's designation as unclassifiable/
attainment for the 8-hour ozone NAAQS, and include components
illustrating how each Parish will continue in attainment of the 8-hour
ozone NAAQS and contingency measures. Each of the section 110(a)(1)
plan components is discussed below.
(a) Attainment Inventory. The LDEQ developed comprehensive
inventories of volatile organic compound (VOC) and nitrogen oxide
(NOX) emissions from area, stationary, and mobile sources
using 2002 as the base year to demonstrate maintenance of the 8-hour
ozone NAAQS for Lafayette and Lafourche Parishes. The year 2002 is an
appropriate year for the LDEQ to base attainment level emissions
because States may select any one of the three years on which the 8-
hour attainment designation was based (2001, 2002, and 2003). The
State's submittals contain the detailed inventory data and summaries by
source category. The 2002 base year inventory is a good choice. Using
the 2002 inventory as a base year reflects one of the years used for
calculating the air quality design values on which the 8-hour ozone
designation decisions were based. It also is one of the years in the
2002-2004 period used to establish baseline visibility levels for the
regional haze program.
A practical reason for selecting 2002 as the base year emission
inventory is that Section 110(a)(2)(B) of the CAA and the Consolidated
Emissions Reporting Rule (67 FR 39602, June 10, 2002) require States to
submit emissions inventories for all criteria pollutants and their
precursors every three years, on a schedule that includes the emissions
year 2002. The due date for the 2002
[[Page 15413]]
emissions inventory was established in the rule as June 2004. In
accordance with these requirements, the State of Louisiana compiles a
statewide emissions inventory for point sources on an annual basis. For
stationary point sources in Lafayette and Lafourche Parishes, the LDEQ
provided estimates for each commercial or industrial operation that
emits 100 tons or more per year of VOC or 100 tons or more per year of
NOX in Appendix A of each maintenance plan. Stationary non-
point source data was provided by E.H. Pechan & Associates, Inc.,
through the Central Regional Air Planning Association (CENRAP) using
the methodology in ``Consolidation of Emissions Inventories'', section
C, page 26. On-road mobile emissions of VOC and NOX were
estimated using EPA's MOBILE6.2 motor vehicle emissions factor computer
model. Non-road mobile emissions data were derived from the ``Emission
Inventory Development For Mobile Sources and Agricultural Dust Sources
for the Central States'' produced by Sonoma Technology, Inc. for CENRAP
in October 2004 using EPA's NONROAD 2004 non-road mobile emissions
computer model. EPA finds that the LDEQ prepared the 2002 base year
emissions inventories for the two Parishes consistent with EPA's long-
established guidance memoranda.
In projecting data for the attainment year 2014 inventory, LDEQ
used several methods to project data from the base year 2002 to the
years 2008, 2011, and 2014. These projected inventories were developed
using EPA-approved technologies and methodologies. Point source and
non-point source projections were derived from the Emissions Growth
Analysis System version 4.0 (EGAS 4.0). Non-road mobile projections
were derived from EGAS 4.0, as well as from the National Mobile
Inventory Model.
The following tables provide VOC and NOX emissions data
for the 2002 base attainment year inventory, as well as projected VOC
and NOX emission inventory data for the years 2008, 2011,
and 2014. Please see the Technical Support Document (TSD) for
additional emissions inventory data including projections by source
category for each parish.

As shown in the table above, total VOC and total NOX
emissions for Lafayette Parish are projected to decrease over the 10-
year period of the maintenance plan.

Total NOX................................... 14.24 13.06 12.51 12.06
----------------------------------------------------------------------------------------------------------------
As shown in the table above, total VOC and total NOX
emissions for Lafourche Parish are projected to decrease over the 10-
year period of the maintenance plan.
Please see the TSD for more information on EPA's analysis and
review of the State's methodologies, modeling data and performance,
etc. for developing the base and attainment year inventories. As shown
in the tables above, the State has demonstrated that the future year 8-
hour ozone emissions will be less than the 2002 base attainment year's
emissions. The attainment inventories submitted by the LDEQ for these
areas are consistent with the criteria as discussed in the EPA
Maintenance Plan Guidance memo dated May 20, 2005. EPA finds that the
future emissions levels in 2008, 2011 and 2014 for total VOC and total
NOX are expected to be less than the emissions levels in
2002.
(b) Maintenance Demonstration. The primary purpose of a maintenance
plan is to demonstrate how an area will continue to remain in
compliance with the 8-hour ozone standard for the 10-year period
following the effective date of designation as unclassifiable/
attainment. The end projection year is 10 years from the effective date
of the attainment designation, which for Lafayette and Lafourche
Parishes was June 15, 2004. Therefore, these plans must demonstrate
attainment through 2014. As discussed in section (a) Attainment
Inventory above, Louisiana has identified the level of ozone-forming
emissions in Lafayette and Lafourche Parishes that were consistent with
attainment of the NAAQS for ozone in 2002. Louisiana has projected VOC
and NOX emissions for the years 2008, 2011, and 2014 in
Lafayette and Lafourche Parishes and EPA finds that the future
emissions levels for total VOC and total NOX in those years
are expected to be below the emissions levels in 2002. Please see the
TSD for more information on EPA's review and evaluation of the State's
2008, 2011, and 2014 projected emissions inventories.
Louisiana relies on several air quality measures that will provide
for additional 8-hour ozone emissions reductions in Lafayette and
Lafourche Parishes. These measures include the following, among others:
(1) Implementation of EPA's National Rule for VOC Emission Standards
for Automobile Refinish Coatings (63 FR 48806), Consumer Products (63
FR 48819), and Architectural Coatings (63 FR 48848), (2) enacting of
specific requirements from EPA's Tier 2 Motor Vehicle Emission
Standards (65 FR 6697), EPA's Heavy-Duty Engine and Vehicle Standards
(66 FR 5002), as well as EPA's gasoline and highway diesel fuel sulfur
control requirements (66 FR
[[Page 15414]]
5002), (3) EPA's required control of emissions from non-road diesel
engines and fuels (69 FR 38958), and (4) implementation of the Federal
Clean Air Interstate Rule (CAIR) (70 FR 25162). The purpose of these
control measures is to reduce levels of 8-hour ozone, including the
areas of Lafayette and Lafourche Parishes.
As an additional demonstration of maintenance, Louisiana references
the EPA modeling conducted for CAIR, in the maintenance plan
submittals. Louisiana is a state that must implement CAIR, and the EPA
CAIR modeling indicates that all Louisiana parishes will be in
attainment with the 8-hour ozone standard by 2010, with continued
attainment projected through 2015. This analysis is consistent with the
projections discussed above in (a) Attainment Inventory.
(c) Ambient Air Quality Monitoring. The State of Louisiana has
committed in its maintenance plans for Lafayette and Lafourche Parishes
to continue operation of an appropriate, EPA-approved, ozone monitoring
network and to work with EPA in compliance with 40 CFR Part 58 with
regard to the continued adequacy of the network, if additional
monitoring is needed, and when monitoring can be discontinued. The 8-
hour ozone NAAQS is 0.08 ppm based on the three-year average of the
fourth-highest daily maximum 8-hour average ozone concentration
measured at each monitor within an area. The standard is considered to
be attained at 84 parts per billion (ppb).
The Lafayette monitoring site has monitored attainment with the 8-
hour ozone standard since 1998. The three most recent 8-hour ozone
design values at the time of the October 2006 submission of the
maintenance plan for Lafayette Parish were 78 ppb for 2003, 79 ppb for
2004, and 82 ppb for 2005. Due to issues with the lease agreement at
the monitoring site location, the Lafayette monitoring site location
was relocated to its current location on the campus of Louisiana State
University. Sampling started at the current location on December 12,
2005, for the beginning of the 2006 ozone season. (The ozone season in
the State of Louisiana is from January to December for the Parishes
discussed in this notice.) Since the 8-hour ozone design value is based
on a three-year average of the fourth-highest daily maximum 8-hour
average ozone concentration, the first available design value for the
current monitoring location will be available once three ozone
monitoring seasons (2006, 2007 and 2008) have been completed. According
to the most recent data available in EPA's Air Quality System (AQS) for
the current Lafayette monitoring site, the annual fourth highest daily
maximum values are 84 ppb for 2006 and 73 ppb for 2007 based on
preliminary data from the January 2007 through September 2007
timeframe. Based on the NAAQS standard discussed above, each of the
design values for Lafayette Parish is considered to be in attainment of
the 8-hour ozone NAAQS and demonstrates that Lafayette Parish is
expected to continue attainment of the 8-hour ozone NAAQS.
The Lafourche monitoring site, which was relocated at the end of
1999 to its current location, has monitored attainment with the 8-hour
ozone standard since 2001. The three most recent 8-hour ozone design
values at the time of December 2006 submission of the maintenance plan
for Lafourche Parish were 78 ppb for 2003, 76 ppb for 2004, and 79 ppb
for 2005. Based upon the most recent data available in AQS for the
Lafourche monitoring site, the design value for 2006 was 80 ppb and a
preliminary design value for 2007 is 79 ppb based on data from the
January 2007 through September 2007 timeframe. Based on the NAAQS
standard discussed above, each of these design values for Lafourche
Parish is considered to be in attainment of the 8-hour NAAQS and
further demonstrates that Lafourche Parish is expected to continue
attainment of the 8-hour ozone NAAQS.
(d) Contingency Plan. The section 110(a)(1) maintenance plans
include contingency provisions to promptly correct any violation of the
NAAQS that occurs. The contingency indicator for the Lafayette and
Lafourche Parish maintenance plans is based upon monitoring. The
triggering mechanism for activation of contingency measures is a
monitoring violation of the 8-hour ozone standard and analysis of data
to determine the cause of the violation. In these maintenance plans, if
contingency measures are triggered, LDEQ is committing to implement the
measures as expeditiously as practicable, but no longer than 24 months
following the trigger.
The following contingency measures are identified for
implementation: (1) Lowering VOC RACT applicability thresholds for
Stage 1 gasoline controls, (2) NOX controls on major sources
(100 tpy and greater), (3) Emission offsets for permits (1.10 ratio for
VOC and NOX), and (4) Other measures deemed appropriate at
the time as a result of advances in control technologies. These
contingency measures and schedules for implementation satisfy EPA's
long-standing guidance on the requirements of section 110(a)(1) for
continued attainment. Continued attainment of the 8-hour ozone NAAQS in
the areas of Lafayette and Lafourche Parishes will depend, in part, on
the air quality measures discussed previously (see II (b) above). The
State will continue to operate an appropriate, EPA-approved, ambient
ozone monitoring site in Lafayette and Lafourche Parish to verify
continued attainment of the 8-hour ozone NAAQS. The air monitoring
results will reveal changes in the ambient air quality as well as
assist the State in determining whether or not implementation of any
contingency measures is necessary. The state will continue to work with
the EPA through the air monitoring network review process, as required
by 40 CFR Part 58, to determine: (1) The adequacy of the ozone
monitoring network; (2) if additional monitoring is needed; and (3)
when monitoring can be discontinued. Air monitoring data will continue
to be quality assured according to federal requirements.
III. Final Action
Pursuant to section 110 of the Act, EPA is approving the 8-hour
ozone maintenance plans for Lafayette and Lafourche Parishes, which
were submitted by LDEQ on October 13, 2006, and December 19, 2006,
respectively, which ensure continued attainment of the 8-hour ozone
NAAQS through the year 2014. We have evaluated the State's submittals
and have determined that they meet the applicable requirements of the
Clean Air Act and EPA regulations, and are consistent with EPA policy.
EPA is publishing this rule without prior proposal because we view
this as a non-controversial amendment and anticipate no adverse
comments. However, in the proposed rules section of this Federal
Register publication, we are publishing a separate document that will
serve as the proposal to approve the SIP revision if relevant adverse
comments are received. This rule will be effective on May 23, 2008,
without further notice unless we receive adverse comment by April 23,
2008. If we receive adverse comments, we will publish a timely
withdrawal in the Federal Register informing the public that the rule
will not take effect. We will address all public comments in a
subsequent final rule based on the proposed rule. We will not institute
a second comment period on this action. Any parties interested in
commenting must do so now. Please note that if we receive adverse
comment on an amendment, paragraph, or section of this rule and if that
provision may be
[[Page 15415]]
severed from the remainder of the rule, we may adopt as final those
provisions of the rule that are not the subject of an adverse comment.
IV. Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is not a ``significant regulatory action'' and therefore is not
subject to review by the Office of Management and Budget. For this
reason, this action is also not subject to Executive Order 13211,
``Actions Concerning Regulations That Significantly Affect Energy
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action
merely approves state law as meeting Federal requirements and imposes
no additional requirements beyond those imposed by state law.
Accordingly, the Administrator certifies that this rule will not have a
significant economic impact on a substantial number of small entities
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because
this rule approves pre-existing requirements under state law and does
not impose any additional enforceable duty beyond that required by
state law, it does not contain any unfunded mandate or significantly or
uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4).
This rule also does not have tribal implications because it will
not have a substantial direct effect on one or more Indian tribes, on
the relationship between the Federal Government and Indian tribes, or
on the distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified by Executive Order 13175 (65
FR 67249, November 9, 2000). This action also does not have Federalism
implications because it does not have substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government, as specified in Executive Order 13132 (64
FR 43255, August 10, 1999). This action merely approves a state rule
implementing a Federal standard, and does not alter the relationship or
the distribution of power and responsibilities established in the CAA.
This rule also is not subject to Executive Order 13045 ``Protection of
Children from Environmental Health Risks and Safety Risks'' (62 FR
19885, April 23, 1997), because it is not economically significant.
In reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act. In
this context, in the absence of a prior existing requirement for the
State to use voluntary consensus standards (VCS), EPA has no authority
to disapprove a SIP submission for failure to use VCS. It would thus be
inconsistent with applicable law for EPA, when it reviews a SIP
submission, to use VCS in place of a SIP submission that otherwise
satisfies the provisions of the CAA. Thus, the requirements of section
12(d) of the National Technology Transfer and Advancement Act of 1995
(15 U.S.C. 272 note) do not apply. This rule does not impose an
information collection burden under the provisions of the Paperwork
Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this rule and other
required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A major rule cannot
take effect until 60 days after it is published in the Federal
Register. This action is not a ``major rule'' as defined by 5 U.S.C.
804(2).
Under section 307(b)(1) of the CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by May 23, 2008. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this rule for the purposes of judicial review nor does
it extend the time within which a petition for judicial review may be
filed, and shall not postpone the effectiveness of such rule or action.
This action may not be challenged later in proceedings to enforce its
requirements. (See section 307(b)(2).)

(i) Approval. The Louisiana Department of Environmental Quality
(LDEQ) submitted 8-hour ozone maintenance plans for the Lafayette and
Lafourche Parish areas on October 13, 2006 and December 19, 2006,
respectively. The two areas are designated unclassifiable/attainment
for the 8-hour ozone standard. EPA determined these requests for
Lafayette and Lafourche Parishes were complete on November 30, 2006 and
May 2, 2007, respectively. These maintenance plans meet the
requirements of section 110(a)(1) of the Clean Air Act, and are
consistent with EPA's maintenance plan guidance document dated May 20,
2005. The EPA therefore approved the 8-hour ozone maintenance plans for
the Lafayette and Lafourche Parish areas on March 24, 2008.
