AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Direct final rule.

SUMMARY:

EPA is approving revisions to the Louisiana State Implementation Plan (SIP) concerning maintenance plans addressing the 1997 8-hour ozone standard for the parishes of Calcasieu and St. James. On July 20, 2007, and August 24, 2007, the State of Louisiana submitted separate SIP revisions containing maintenance plans for the 1997 ozone standard for Calcasieu and St. James Parishes, respectively. These plans ensure the continued attainment of the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) through the year 2014. On March 12, 2008, EPA issued a revised ozone standard. Today's action, however, is being taken to address requirements under the 1997 ozone standard. Requirements for these areas under the 2008 standard will be addressed in future actions. 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 December 8, 2008 without further notice, unless EPA receives relevant adverse comment by November 10, 2008. If EPA receives such comment, EPA will publish a timely withdrawal in the Federal Register informing the public that this rule will not take effect.

IV. Statutory and Executive Order Reviews

I. Background

Under section 107 of the 1977 CAA, Louisiana's Calcasieu and St. James 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). Under the 1990 CAA Amendments, the Calcasieu and St. James 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.

In two separate submittals in the mid-1990's, Louisiana submitted requests to redesignate Calcasieu Parish and St. James Parish to attainment for the 1-hour ozone standard. As part of each submittal, the State provided the required ozone monitoring data and maintenance plan 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. EPA approved Louisiana's requests to redesignate these Parishes to attainment for the 1-hour ozone standard and approved the maintenance plan on May 2, 1997 (62 FR 24036), with an effective date of June 2, 1997.

On April 30, 2004, EPA designated and classified areas for the 1997 8-hour ozone NAAQS (69 FR 23858), and published the final Phase 1 rule for implementation of the 1997 ozone NAAQS (69 FR 23951). Calcasieu and St. James Parishes were designated as unclassifiable/attainment for the 1997 ozone standard, effective June 15, 2004. Consequently, both of these attainment areas 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 Phase 1 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). This SIP revision satisfies the section 110(a)(1) CAA requirements for a plan that provides for implementation, maintenance, and enforcement of the 1997 8-hour ozone NAAQS in the Calcasieu and St. James Parish 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 1997 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. See 489 F.3d 1245 (D.C. Cir. 2007), cert. denied, 128 S.Ct. 1065 (2008). The Court vacated those portions of the Rule that provide for regulation of the 1997 8-hour ozone NAAQS 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 implementation rule for the 1997 8-hour ozone NAAQS for maintenance plans.

II. Analysis of the State's Submittals

On July 20, 2007, and August 24, 2007, the State of Louisiana submitted separate SIP revisions containing maintenance plans for the 1997 ozone NAAQS for Calcasieu and St. James Parishes. These July and August revisions provide 1997 ozone NAAQS 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 1997 ozone NAAQS in Calcasieu and St. James Parishes.

In this action, EPA is approving the State's maintenance plans for the 1997 ozone NAAQS for the areas of Calcasieu and St. James Parishes because EPA finds that the LDEQ submittal meets 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 1997 ozone NAAQS in the area for 10 years from the effective date of the area's designation as unclassifiable/attainment for the 1997 ozone NAAQS, and include components illustrating how each Parish will continue in attainment of the 1997 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 VOC and NOX emissions from area, stationary, and mobile sources using 2002 as the base year to demonstrate maintenance of the 1997 ozone NAAQS for Calcasieu and St. James 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 for the 1997 ozone NAAQS 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) Start Printed Page 59520require 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 emissions inventory is established in the rule as June 2004. In accordance with these requirements, the State of Louisiana compiles a statewide EI for point sources on an annual basis. For stationary point sources, for Calcasieu and St. James Parishes, the LDEQ provided estimates for each commercial or industrial operation that emits 100 tons or more per year of VOC or 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.

Calcasieu Parish VOC and NOX Emissions Inventory Baseline (2002) and Projections (2008, 2011, and 2014)

[Tons per day]

Emissions2002200820112014
Total VOC49.5948.4048.5648.93
Total NOX133.35133.18135.99138.94

As shown in the Table, total VOC and total NOX emissions for Calcasieu Parish are projected to decrease slightly, and increase slightly, respectively, over the 10-year period of the maintenance plan. While emission projections for VOC indicate a downward trend through 2014, NOX emission projections through 2014 show an increase of 5.59 tons per day, or approximately 4 percent (from 133.35 to 138.94 tpd). This projected increase is relatively small considering that it occurs over a period of approximately twelve (as from the 2002 baseline) years. The slightly upward trend in NOX emissions results from projected increases in emissions for the point and non-point source categories. The EGAS system for projecting emissions tends to overstate future emissions since the system relies principally on economic growth for the projections. Specifically, the projected future emissions from NOX point sources is overstated because the projections do not include reductions from regulatory or permit controls, or account for reductions from consent decrees. The control measures contained in rules for point and non-point stationary sources, which were not included in the EGAS program, which was used to project emissions for Calcasieu Parish, are expected to fully offset the slight increase in NOX in Calcasieu Parish which was projected without the controls. Emissions of NOX from non-road mobile and on-road mobile sources are projected to decrease.

St. James Parish VOC and NOX Emissions Inventory Baseline (2002) and Projections (2008, 2011, and 2014)

[Tons per day]

Emissions2002200820112014
Total VOC7.817.908.098.28
Total NOX38.8340.7442.0242.98

As shown in the table above, total VOC and total NOX emissions for St. James Parish are both projected to increase slightly over the 10-year period of the maintenance plan. Emission projections for VOC indicate an increase of 0.47 tons through 2014, which is an increase of approximately 6 percent (from 7.81 to 8.28 tpd). The slightly upward trend in VOC emissions results primarily from the point source category, although there is also projected to be a very small increase from the nonpoint source category. VOC emissions from nonroad mobile and onroad mobile sources are projected to decrease. For NOX, emission projections through 2014 show an increase of 4.15 tons per day, or approximately 10 percent (from 38.83 to 42.98 tpd). These projected increases are relatively small considering that they occur over a period of approximately twelve (as from the 2002 baseline) years. The slightly upward trend in NOX emissions results from projected increases in emissions for the point and non-road mobile source categories. One will note that the absolute number of tons per day for both VOC and NOX is very small, making any change (either an increase or a decrease) appear more pronounced when it is calculated as a percentage. In absolute terms, these are de minimis increases. Additionally, Louisiana's projections for the total NOX emissions in 2014 did not Start Printed Page 59521take into account regulatory controls which will reduce actual VOC and NOX emissions from point and stationary non-point (area) sources, as well as non-road mobile sources. National rules which were not included in the growth estimates include EPA's rules for VOC emission standards for Consumer and Commercial Products and EPA's Locomotive and Marine Compression-Ignition Engines rule. Also, a consent decree which includes a large refinery in the area that was not accounted for in the projections is expected to further reduce actual VOC and NOX emissions.

EPA is aware that a company has applied for a permit with the LDEQ to construct a large facility in St. James. We do not want to prejudge whether the permit will be issued, but the proposed emissions in the company's permit application for this facility: (1) Are large relative to this rural area's emissions (as noted above, the absolute number of tons per day for both VOC and NOX is very small in this area), (2) ordinarily would not be accounted for using the EPA's methodologies for growth estimates in a maintenance plan, and (3) could potentially impact the Baton Rouge ozone nonattainment area. The company, however, will have to satisfy the Prevention of Significant Deterioration (PSD) SIP permitting requirements by demonstrating that this facility will not interfere with maintenance in St. James and will not contribute to nonattainment in the Baton Rouge area. With this safeguard, we believe continued maintenance in the St. James Parish will be protected.

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 for the two areas. As shown in the tables and discussion above, the State has demonstrated that the future year ozone precursor emissions will be less than or similar to 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 and in other guidance documents (please see the docket for additional information). Considering emissions projections together with reductions from measures not accounted for in the state's projections, EPA finds that the future emissions levels in 2008, 2011 and 2014 are expected to be less than or similar to 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 1997 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 for the 1997 ozone NAAQS, which for Calcasieu and St. James 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 Calcasieu and St. James 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 Calcasieu and St. James Parishes and EPA finds that the future emissions levels in those years are expected to be similar to or 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 Calcasieu and St. James Parishes. These measures include the following, among others: (1) Implementation of EPA's National Rules for VOC Emission Standards: For Automobile Refinish Coatings (63 FR 48806), for Consumer Products (63 FR 48819), and Architectural Coatings (63 FR 48848), for Consumer and Commercial Products Group II (Flexible Packaging Printing Materials, Lithographic Printing Materials, Letterpress Printing Materials) (71 FR 58745), for Consumer and Commercial Products Group III (Paper, Film, and Foil Coatings, Metal Furniture Coatings, and Large Appliance Coatings) (72 FR 57215), and for Consumer and Commercial Products Group IV (to be published in the fall of 2008); (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 and Highway Diesel Fuel Sulfur Control Requirements (66 FR 5001), as well as EPA's Tier 2 Motor Vehicle Emissions Standards and Gasoline Sulfur Control requirements (65 FR 6697); (3) EPA's required control of emissions from Non-road Diesel Engines and Fuels (69 FR 38958); and (4) EPA's Locomotive and Marine Compression-Ignition Engines rule (73 FR 16435). The purpose of these control measures is to reduce levels of 8-hour ozone, including the areas of Calcasieu and St. James Parishes.

(c) Ambient Air Quality Monitoring. The State of Louisiana has committed in its maintenance plans for Calcasieu and St. James Parishes to provide operation of an appropriate ozone monitoring network and to work with EPA in compliance with 40 CFR part 58 with regard to the continued adequacy of such a network.

The Convent monitoring site in St. James Parish has monitored attainment with the 1997 ozone standard from 2002 through 2007. The 1997 ozone NAAQS is 0.08 parts per million 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 1997 ozone standard is considered to be attained at 84 parts per billion (ppb). At the time the maintenance plan was submitted by LDEQ, the three most recent 8-hour ozone design values for the Convent site in St. James Parish are 73 ppb for 2003, 73 ppb for 2004, and 76 ppb for 2005. Also, the design value for St. James Parish for 2006 is 76 ppb, and the design value for 2007 is 77 ppb.

In Calcasieu Parish there are three monitoring sites, each of which has monitored attainment with the 1997 ozone standard from 2002 through 2005. At the time the maintenance plan was submitted by LDEQ, the three most recent 8-hour ozone design values for Calcasieu Parish are 78 ppb for 2003, 80 ppb for 2004, and 83 ppb for 2005. Also, the design value for Calcasieu Parish for 2006 is 82 ppb, and the design value for 2007 is 81 ppb.

(d) Contingency Plan. The section 110(a)(1) maintenance plans include contingency provisions to correct promptly any violation of the 1997 ozone NAAQS that occurs. The contingency indicator for the Calcasieu and St. James Parish maintenance plans is based upon monitoring data. The triggering mechanism for activation of contingency measures is a monitoring violation of the 1997 ozone standard. 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) of continued Start Printed Page 59522attainment. Continued attainment of the 1997 ozone NAAQS in the areas of Calcasieu and St. James Parishes will depend, in part, on the air quality measures discussed previously (see II.(b) above). In addition, Louisiana commits to verify the 8-hour ozone status in each maintenance plan through appropriate ambient air quality monitoring, and to quality assure air quality monitoring data according to federal requirements.

III. Final Action

Pursuant to section 110 of the Act, EPA is approving the 1997 8-hour ozone maintenance plans for Calcasieu and St. James Parishes, which were submitted by LDEQ on July 20, 2007 and August 24, 2007, respectively, which ensure continued attainment of the 1997 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 is 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 December 8, 2008 without further notice unless we receive adverse comment by November 10, 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 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 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 approves 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 Order 12866 (58 FR 51735, October 4, 1993);
  • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
  • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
  • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
  • Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
  • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
  • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
  • Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the Clean Air Act; and
  • Does not provide EPA with the discretionary authority to address, 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, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.

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 action 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 Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by December 8, 2008. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action 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).)

(j) Approval. The Louisiana Department of Environmental Quality (LDEQ) submitted 1997 8-hour ozone NAAQS maintenance plans for the areas of Calcasieu and St. James Parishes on July 20, 2007, and August 24, 2007, respectively. The two areas are designated unclassifiable/attainment for the 1997 8-hour ozone standard. EPA determined these requests for Calcasieu and St. James Parishes were complete on October 5, 2007, and October 16, 2007, respectively. The 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 1997 8-hour ozone NAAQS maintenance plans for the areas of Calcasieu and St. James Parishes on October 9, 2008.
