DOCUMENT ACTION: Final rule.

SUBJECT CATEGORY: Determination of Nonattainment as of November 15, 1996 and Reclassification of the Beaumont/Port Arthur Ozone Nonattainment Area; State of Texas; Final Rule

DATES: This final rule is effective on April 29, 2004.

DOCUMENT SUMMARY: Pursuant to the U.S. Court of Appeals for the Fifth Circuit's (the Court) reversal, the EPA is withdrawing its final action that extended the attainment date to November 15, 2007, and approved the transport demonstration (66 FR 26914) for the Beaumont/Port Arthur 1 hour ozone nonattainment area (the BPA area). The EPA finds that the BPA area has failed to attain the 1hour ozone national ambient air quality standard (NAAQS or standard) by November 15, 1996, the attainment date for moderate nonattainment areas set forth in the Federal Clean Air Act (Act or CAA). As a result, the BPA area is reclassified by operation of law as a serious 1hour ozone
nonattainment area. The new serious area attainment date for the BPA area is as expeditiously as practicable but no later than November 15, 2005. The State of Texas must submit a State Implementation Plan (SIP) revision that meets the serious area 1hour ozone nonattainment area requirements of the Act on or before one year after the effective date of this final action. We are adjusting the dates by which the area must meet the rateofprogress (ROP) requirements and adjusting contingency measure requirements as they relate to the ROP requirements. These final actions are in direct response and to comply with the Court's reversal.

In response to the Court's remand, we are withdrawing our final approval of BPA's 2007 attainment demonstration SIP, the Mobile Vehicle Emissions Budget (MVEB), the midcourse review commitment (MCR), and our finding that BPA implemented all Reasonable Available Control Measures (RACM). The required revised SIP must include, among other things, a revised attainment demonstration SIP, a new MVEB, and a re analysis of RACM that complies with the Court's order.

I. What Is the Background for This Action?

The BPA area was classified as a moderate 1hour ozone nonattainment area and, therefore, was required to attain the 1hour ozone standard of 0.12 ppm by November 15, 1996. On April 16, 1999, EPA proposed to reclassify the BPA area to a serious ozone nonattainment area, or, in the alternative to extend BPA's attainment date if the State submitted a SIP consistent with the criteria of the Transport Policy. 64 FR 18864. As part of the proposed alternative
reclassification of the area to serious, the EPA proposed to find that the BPA area did not attain the 1hour ozone NAAQS by November 15, 1996, as required by the CAA. The proposed finding was based on 1994 1996 air quality data that showed the area's air quality violated the standard and the area did not qualify for an attainment date extension under the provisions of section 181(a)(5).\1\ EPA also proposed that the appropriate reclassification of the area would be from moderate to serious.
\1\ Section 181(a)(5) specifies that a state may request, and EPA may grant, up to two oneyear attainment date extensions. EPA may grant an extension if: (1) the state has complied with the requirements and commitments pertaining to the applicable
implementation plan for the area, and (2) the area has measured no more than one exceedance of the ozone standard at any monitoring site in the nonattainment area in the year in which attainment is required.

Although the area was not eligible for an attainment date extension under
[[Page 16484]]
CAA section 181(a)(5), the April 16, 1999, proposal included a notice of the BPA area's eligibility for an attainment date extension, pursuant to the Transport Policy, which was published in a March 25, 1999, Federal Register notice (64 FR 14441). This policy addressed circumstances where pollution from upwind areas interferes with the ability of a downwind area to attain the 1hour ozone standard by its attainment date. EPA proposed to finalize its action on the determination of nonattainment and reclassification of the BPA area only after the area had received an opportunity to qualify for an attainment date extension under the Transport Policy.

The State of Texas submitted a request for an extension of the attainment date for the BPA area, a transport demonstration, an attainment demonstration SIP and MVEB, an MCR enforceable commitment, and RACM analysis. We proposed on December 27, 2000, to approve the transport demonstration and to extend the attainment date without reclassifying the area, to approve the attainment demonstration SIP and MVEB, to approve the MCR commitment, and to find that BPA was implementing all RACM. (65 FR 81786)

On May 15, 2001, EPA issued a final rule (66 FR 26914) in which EPA approved the transport demonstration and extended the attainment date for the BPA area to November 15, 2007, while retaining the area's classification as ``moderate.'' The rule also approved the attainment demonstration for the BPA area and MVEB, approved the State's enforceable commitment to perform a midcourse review and submit a SIP revision by May 1, 2004, found that the area was implementing all RACM, and took one other nonrelated action. The attainment demonstration SIP is addressed in the State of Texas submittals dated November 12, 1999, and April 25, 2000. Thus, the area would have had until no later than November 15, 2007, the attainment date for the upwind HoustonGalveston (HG) nonattainment area, to attain the 1hour ozone standard. The final rule contains EPA's responses to the comments. (We also took one final action not relevant to today's action and the Court's remand: the finding that BPA met the Reasonably Available Control Technology (RACT) requirements for major sources of Volatile Organic Compounds (VOC) emissions.)

A petition for review of the May 15, 2001, rulemaking was filed in the U.S. Court of Appeals for the Fifth Circuit. On December 11, 2002, the Court issued a decision in Sierra Club v. EPA, 314 F.3d 735 (5th Cir. 2002), reversing the portion of EPA's approval that extended BPA's attainment date to 2007 under the Transport Policy without reclassifying the area.\2\ The Court also remanded to EPA the final actions related to the reversal: our approval of the attainment demonstration SIP and MVEB, the MCR commitment, and our finding that the area was implementing all RACM. The Court affirmed the portion of EPA's final action that requires implementation only of control measures that contribute to attainment as expeditiously as practicable and considers implementation costs in rejecting control measures, but remanded EPA's specific determination regarding RACM in the BPA area so that any conclusions about the control measures may be adequately explained.
\2\ Two other United States Circuit Courts of Appeals had previously issued decisions rejecting transportbased attainment date extensions that EPA had granted in other areas. Sierra Club v. EPA, 294 F.3d 155 (D.C. Cir. 2002) and Sierra Club v. EPA, 311 F.3d 853 (7th Cir. 2002). In the wake of these decisions, EPA issued final rulemakings reclassifying the Washington, DC ozone
nonattainment area, 68 FR 3410 (January 24, 2003), and the St. Louis ozone nonattainment area, 68 FR 4835 (January 30, 2003). (EPA subsequently redesignated the St. Louis area to attainment for the ozone standard 68 FR 25418 and 68 FR 25442 (May 12, 2003).) In addition, in light of the three circuit court decisions, EPA issued final rules withdrawing transportbased attainment date extensions and reclassifying the Baton Rouge and the Atlanta ozone
nonattainment areas, (68 FR 20077 (April 24, 2003), and 68 FR 55469 (September 26, 2003), respectively).

EPA published a Supplemental Proposed rule dated June 19, 2003 (68 FR 36756). In response to the Court's reversal, EPA proposed to withdraw its final action that extended the attainment date to November 15, 2007, and approved the transport demonstration. We also proposed to issue a finding that BPA failed to attain the 1hour ozone national ambient air quality standard (NAAQS or standard) by November 15, 1996, the attainment date for moderate nonattainment areas set forth in the Act, and to reclassify BPA as a serious 1hour ozone nonattainment area. EPA also proposed that should we take final action on the reclassification to serious, we would also take one of two alternative options for identifying the appropriate attainment date for the area. Under Option 1, EPA proposed further to find that the area failed to attain the 1hour ozone standard by November 15, 1999, the attainment date for serious nonattainment areas. If EPA took final action on that finding, the area would be reclassified as a severe 1hour ozone nonattainment area, with an attainment date of no later than November 15, 2005. Alternatively, under Option 2, if the area were reclassified as a serious 1hour ozone nonattainment area, EPA proposed that it would retain that classification, but that it would have an attainment date of no later than November 15, 2005. Under either alternative, we proposed that the State of Texas submit the required SIP revision on or before one year after the effective date of a final action on this notice. We further proposed to adjust the dates by which the area must meet the rateofprogress (ROP) requirements and adjust contingency measure requirements as they relate to the ROP requirements.

In response to the Court's remand, we also proposed to withdraw our final approval of BPA's 2007 attainment demonstration SIP, the MVEB, the midcourse review commitment (MCR), and our finding that BPA implemented all RACM. We also proposed the schedule for Texas to submit a revised SIP, a new MVEB, and a reanalysis of RACM meeting the Court's order.

II. What Are the National Ambient Air Quality Standards?

Since the CAA's inception in 1970, EPA has set NAAQS for six common air pollutants: carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide. The CAA requires that these standards be set at levels that protect public health and welfare with an adequate margin of safety. These standards present state and local governments with the air quality levels they must meet to achieve clean air. Also, these standards allow the American people to assess whether or not the air quality in their communities is healthful.

III. What Is the NAAQS for Ozone?

The NAAQS for ozone is expressed in two forms called the 1hour and 8hour \3\ standards. Table 1 summarizes the 1hour ozone standards. \3\ The 8hour ozone standard value is 0.08 ppm and is the primary and secondary standard. The standard requires that the average of the annual fourth highest daily maximum 8hour average ozone concentration measured at each monitor over any threeyear period, be less than or equal to 0.08 ppm. EPA intends to designate areas under the 8hour standard by April 15, 2004.
[[Page 16485]]
Table 1.Summary of Ozone Standards Standard Value Type Method of compliance 1hour..................... 0.12 ppm............ Primary and Secondary............... Must not be exceeded, on average, more than one day per year over any threeyear period at any monitor within an area. 8hour..................... 0.08 ppm............ Primary and Secondary............... Three year average of the annual fourth highest value at any specific monitor must not exceed the standard. (Primary standards are designed to protect public health and secondary standards are designed to protect public welfare and the environment.) Eventually the 8hour standard will replace the one hour standard. EPA is currently developing a transition policy from the one hour standard to the eight hour standard that will explain which one hour requirements must remain in place (68 FR 32802).

At this time the 1hour ozone standard continues to apply to the BPA area, and it is the classification of the BPA area with respect to the 1hour ozone standard addressed in this document.
IV. What Is a SIP and How Does It Relate to the NAAQS for Ozone?

Section 110 of the CAA requires states to develop air pollution regulations and control strategies to ensure that state air quality meet the NAAQS established by EPA. Each state must submit these regulations and control strategies to us for approval and incorporation into the Federallyenforceable SIP.

Each Federallyapproved SIP protects air quality primarily by addressing air pollution at its point of origin. These SIPs can be extensive. They may contain state regulations or other enforceable documents and supporting information such as emission inventories, monitoring networks, and modeling demonstrations.

V. What Is the Beaumont/Port Arthur Nonattainment Area?

The Beaumont/Port Arthur 1hour ozone nonattainment area is located in Southeast Texas, and consists of Hardin, Jefferson, and Orange Counties.

VI. What Is the Additional Context for This Rulemaking?

The Transport Policy provided for an extension of an area's attainment date if it was adversely affected by transport, without having to reclassify the affected area. Consequently, when we granted the extension of the attainment date for BPA based upon the transport demonstration, we did not take action to finalize the April 16, 1999, proposed finding that BPA had not attained the 1hour ozone standard by November 15, 1996. We therefore did not reclassify BPA from ``moderate'' to ``serious.'' The Court's ruling means that BPA's attainment date extension while retaining the ``moderate'' classification, using the Transport Policy, is no longer valid. VII. Application of the CAA Provisions Regarding Determinations of Nonattainment and Reclassifications

A. Serious Classification

Section 181(b)(2) of the Act requires that we determine, based on the area's design value (as of the attainment date), whether an ozone nonattainment area attained the onehour ozone standard by that date. If we find that the nonattainment area has failed to attain the one hour ozone standard by the applicable attainment date, the area is reclassified by operation of law to the higher of the next higher classification for the area, or the classification applicable to the area's design value as determined at the time of the required Federal Register notice.

We make attainment determinations for ozone nonattainment areas using available qualityassured air quality data. For the BPA ozone nonattainment area, the attainment determination is based on 19941996 air quality data. The data show that for 19941996, four monitoring sites averaged more than one exceedance day per year. This data calculates to a design value of .157 ppm. Therefore, pursuant to section 181(b) of the CAA, we find that the BPA area did not attain the 1hour ozone NAAQS by the November 15, 1996, deadline for moderate areas. Additional background for this finding may be found in the April 16, 1999, proposal (64 FR 18864), the December 27, 2000, proposal (65 FR 81786), and the May 15, 2001, final rule (66 FR 26914). A summary and discussion of the air quality monitoring data for the BPA area for 1994 through 1996 can be found in the April 16, 1999, proposal and its technical support document (TSD). We received no adverse comments on our findings regarding these air quality data.

Section 181(b)(2)(A) of the Act requires that, when we find that an area failed to attain by the applicable date, the area is reclassified by operation of law to the higher of: the next higher classification or the classification applicable to the area's ozone design value at the time the required notice is published in the Federal Register. The classification applicable to BPA's ozone design value at the time of today's notice is ``moderate'' since the area's 2003 calculated design value, based on qualityassured ozone monitoring data from 20012003, is 0.129 ppm. By contrast, the next higher classification for BPA is ``serious.'' Because ``serious'' is a higher nonattainment classification than ``moderate'' under the statutory scheme, BPA is reclassified by operation of law as ``serious,'' for failing to attain the standard by the moderate area applicable attainment date of November 15, 1996.

B. Selection of Option 2Reclassification to Serious

In EPA's Supplemental Proposed rule dated June 19, 2003 (68 FR 36756), we proposed two options for identifying the appropriate attainment date following a final action on the reclassification of the BPA area to serious. Under Option 1, EPA would make an additional determination of whether BPA attained the standard by November 15, 1999. If we made a final determination that the area failed to attain by the 1999 date, the area would be reclassified as severe with an attainment date of no later than November 15, 2005. Under Option 2, if the area were reclassified as a serious area, EPA would retain the serious classification for the area but the attainment date would be no later than November 15, 2005.

We have concluded that Option 2 is the better choice. We therefore have chosen not to finalize the additional determination of whether the BPA area attained the standard by November 15, 1999. We believe it is appropriate in these special BPA circumstances to retain the serious classification but with a prospective attainment date. Through discussions with representatives from the State, Industry, Environmental Groups, and commenting parties it seems that they agree Option 2 is the better choice considering the BPA area's particular circumstances, history, and facts.
[[Page 16486]]
VIII. What Is the New Attainment Date for the Beaumont/Port Arthur Area?

The new attainment date for the BPA area is as expeditiously as practicable but no later than November 15, 2005. The as expeditiously as practicable attainment date will be determined as part of the action on the required SIP submittal.

IX. What Is the Date for Submitting a Revised SIP for BPA?

EPA must address the schedule by which Texas is required to submit the SIP revision. We proposed the required SIP revision be submitted as expeditiously as practicable but no later than one year after the effective date of our final action. No adverse comments were received by the EPA on this issue. Today, we are requiring that Texas submit the SIP revision as expeditiously as practicable but no later than one year after the effective date of this final action.

Additionally, the implementation of the failure to attain contingency measures in the current SIP is triggered automatically upon the effective date of this rule. Further, Texas is required to submit a revision to the SIP containing contingency measures under sections 172(c)(9) and 182(c)(9) to meet ROP requirements and for failure to attain.

The State's SIP revision submitted for an attainment date of 2007 contained a commitment to perform and submit a midcourse review (MCR) by May 1, 2004. Due to the new time frame for SIP submittal and the attainment date of November 15, 2005, Texas is not required to submit an MCR for the BPA area.
X. Why Are We Withdrawing the Attainment Demonstration, MCR and MVEB Approvals and the RACM Finding, and What Are the Potential Impacts of the Withdrawals?

We are withdrawing our final approval of BPA's 2007 attainment demonstration and the accompanying Motor Vehicle Emission Budget (MVEB), the MCR enforceable commitment, and the Reasonably Available Control Measures (RACM) finding. Having an attainment date earlier than 2007 requires the submission of a revised attainment demonstration SIP, a new MVEB, and a reanalysis of the RACM determination.

To be consistent with the Court's reversal of the 2007 attainment date extension, and to respond to the remand, we are withdrawing our May 15, 2001, approval of the 2007 attainment demonstration and MVEB, the MCR enforceable commitment, and the finding that the area was implementing all RACM. They are no longer applicable as they were based on a 2007 attainment date. A new attainment demonstration with a new MVEB, and a new RACM analysis, are required to be submitted for the BPA area. All are due on or before one year from the effective date of this Final Rule.

As discussed in the June 19, 2003, supplemental proposal, the Court affirmed the portion of our May 15, 2001, final action that treats as potential RACMs only those measures that would advance the attainment date and considers implementation costs when rejecting certain control measures in its December 11, 2002, decision. However, the Court remanded the analysis and conclusions regarding RACM in the BPA area to the EPA. According to the Court's order, the analysis must: (1) demonstrate an examination of all relevant data; and (2) provide a plausible explanation for the rejection of proposed RACMs including why the measures, individually and in combination, would not advance the BPA area's attainment date.

The State is responsible for performing and submitting a new RACM analysis for EPA use in determining SIP approval. Even though the State is responsible for developing the new analysis, when evaluating the use of RACM in the SIP approval process EPA will only consider as adequate an RACM analysis by the State containing the factors outlined in the Court's December 11, 2002, ruling. The RACM analysis is due on or before the attainment demonstration due date.

Withdrawing approval of the MVEB results in reverting to the previously approved MVEBs for the purposes of transportation conformity. This would be the 1996 budget which was for VOCs only and did not include a NOX budget. Therefore, there will be no valid NOX budget in effect until a new NOX MVEB is submitted and found adequate. In order for transportation projects to proceed in the absence of an adequate NOX budget, an area must: (1) pass a ``build/nobuild'' emissions test, meaning that projected future regional emissions from the transportation system after making proposed changes must be lower than the projected emissions from the existing transportation system; and (2) demonstrate that the estimated future emissions will not exceed 1990 levels. See 40 CFR 93.119(b).
XI. How Does the Recent Release of MOBILE6 Interact With
Reclassification?
A. What Is the Relationship Between MOBILE6 and the Attainment Year Motor Vehicle Emissions Budgets?

In addition to the fact that the motor vehicle emissions budgets contained in the State's November 12, 1999, and April 25, 2000, submittals are based on the year 2007, which is no longer an allowable attainment date under the Court's decision, the current MVEB is not based upon the most recent mobile source emission factors model, MOBILE6.

The motor vehicle emissions budgets submitted to fulfill the SIP revision requirements, including those of the attainment demonstration, must be prepared using the latest approved emissions model. See 40 CFR 51.112. EPA approved the MOBILE6 emissions factor model in January 2002. As a result, any new attainment SIP planning must now be based on the MOBILE6 model. The State should refer to applicable guidance and policy, such as ``Policy Guidance for the Use of MOBILE6 in SIP Development and Transportation Conformity'' (memorandum from John S. Seitz and Margo Tsirigotis Oge, January 18, 2002) in preparing the budgets. The revised SIP must contain budgets based on MOBILE6 modeling.
B. What Is the Relationship Between MOBILE6 and the Post1996 Rateof Progress Requirement?

The section 182(c)(2)(B) reasonable further progress requirement requires volatile organic compounds (VOC) or nitrogen oxides (NOX) reductions of 3 percent per year, averaged over a 3 year period, until the attainment date, for serious and above ozone nonattainment areas designated and classified under the 1hour ozone NAAQS. The EPA refers to these reductions as the rateofprogress (ROP) requirement.

The January 18 MOBILE6 policy indicates, among other things, that the motor vehicle emissions budgets in the post1996 rateofprogress plans will have to be developed using MOBILE6. In this policy we said:

In general, EPA believes that MOBILE6 should be used in SIP development as expeditiously as possible. The Clean Air Act requires that SIP inventories and control measures be based on the most current information and applicable models that are available when a SIP is developed.\4\
\4\ See Clean Air Act section 172(c)(3) and 40 CFR 51.112(a)(1).

Texas has not submitted ROP plans other than the original 15% ROP plan
[[Page 16487]]
required for the BPA area as a moderate area, since under the Transport Policy the BPA area was not required to meet the post1996 ROP requirements. The post1996 until the attainment date ROP plans will need to be based upon MOBILE6.

The post1996 rateofprogress requirement flows from section 182(c)(2)(B) which requires serious and above areas to achieve a 3 percent per year reduction in baseline VOC emissions (or some combination of VOC and NOX reductions from baseline emissions pursuant to section 182(c)(2)(C)) averaged over each consecutive threeyear period after November 15, 1996, until the attainment date.\5\ Baseline emissions are the total amounts of actual VOC or NOX emissions from all anthropogenic sources in the area during the calendar year 1990, excluding emissions that would be eliminated under certain Federal programs and Clean Air Act mandates: phase 2 of the Federal gasoline Reid vapor pressure regulations (Phase 2 RVP) promulgated on June 5, 1990 (see 55 FR 23666); the Federal motor vehicle control program in place as of January 1, 1990 (1990 FMVCP); and certain changes and corrections to motor vehicle inspection and maintenance (I/M) programs and corrections and reasonably available control technology (RACT) required under section 182(a)(2).\6\ We have issued guidance that provides detailed information for implementing the rateofprogress provisions of section 182.\7\ Basically our guidance requires the calculation of a target level of emissions for each rate ofprogress milestone year. The target level for any rateofprogress milestone year is the 1990 baseline emissions decreased by the amount of baseline emissions that would be reduced by the 1990 FMVCP, the Phase 2 RVP program, and RACT fixups \8\ by that year and reduced by the amount of the mandated minimum reductions (15 percent VOC by 1996, and an additional nine (9) percent VOC, or VOC and NOX, by 1999, an additional 9 percent VOC, or VOC and NOX, by 2002, and an additional 9 percent VOC, or VOC and NOX, by 2005). Under our guidance, the first rateofprogress milestone year target level, for example, the 15 percent VOC reduction by 1996, starts with the 1990 base year emissions and then subtracts the effects of the 1990 FMVCP and Phase 2 RVP and RACT fixups through 1996 and also subtracts the required 15 percent VOC reduction. The 1999 VOC target level starts with the 1996 target level and subtracts the effects between 1996 and 1999 of the 1990 FMVCP and Phase 2 RVP and RACT fixups and subtracts the required 9 percent post1996 reduction. For each target level, our guidance requires the preparation of a 1990 base year inventory ``adjusted'' to the milestone year (the ``1990 adjusted base year inventory'') to account for the effects of the 1990 FMVCP and Phase 2 RVP and RACT fixups by the milestone year. The adjusted inventory uses 1990 motor vehicle activity levels but emission factors computed by MOBILE6 for the applicable milestone year. For example, preparation of a rateofprogress plan for the ROP milestone year of 1999, with NOX substitution, requires a 1990 base year inventory for both VOC and NOX, a 1990 base year VOC inventory adjusted to 1996, and 1990 base year VOC and NOX inventories adjusted to 1999. Preparation of a rateofprogress plan for 2005 with
NOX substitution requires a 1990 base year inventory for both VOC and NOX plus the following seven ``adjusted'' inventories: 1996 VOC; 1999 VOC and NOX; 2002 VOC and NOX; and 2005 VOC and NOX.
\5\ As a moderate area, BPA was not required to submit a ROP plan for a nine (9) percent reduction for the 3year period November 15, 1996, through November 15, 1999. However, the BPA area now is required to submit an ROP plan through November 15, 2005, the new attainment date.
\6\ These requirements under section 182(a)(2) are known as I/M and RACT corrections or I/M and RACT ``fixups.'' For further explanation of these see 57 FR at 1350313504, April 16, 1992. \7\ This includes: Guidance on the Post1996 RateofProgress Plan (RPP) and Attainment Demonstration, EPA452/R93015 (Corrected version of February 18, 1994). An electronic copy may be found on EPA's Web site at http://www.epa.gov/ttn/oarpg/t1pgm.html (file name: ``post962.zip'').
\8\ The BPA area has no I/M program and so has no I/M fixups to consider. A vehicle I/M program would normally be listed as a requirement for a 1hour ozone moderate or above nonattainment area. However, the Federal I/M Flexibility Amendments of 1995 determined that urbanized areas with populations less than 200,000 for 1990 (such as Beaumont/Port Arthur) are not mandated to participate in the I/M program (60 FR 48033, September 18, 1995).

One consequence of the need to use MOBILE6 emission factors in the post1996 rateofprogress plans is that the area must recompute the 1990 baseline emissions using the MOBILE6 emissions factor model to update the 1990 onroad mobile sources' portion of the 1990 base year emission inventory. The area must also calculate post1996 rateof progress target levels by reiterating the target levels for rateof progress requirements for the 1996 milestone year.

Thus, in addition to vehicle emissions budgets for any applicable milestone year, the post1996 rateofprogress requirement will also require the development of a revision to the 1990 base year emissions inventories and development of up to seven 1990 adjusted inventories (VOC for 1996, VOC and NOX for 1999, VOC and NOX for 2002, plus VOC and NOX for 2005).
XII. What Will Be the RateofProgress and Contingency Measure Schedules?

A. RateofProgress Milestones

Section 182(c)(2)(B) requires serious and above areas to achieve a 3 percent per year reduction in baseline VOC emissions (or some combination of VOC and NOX reductions from baseline emissions pursuant to section 182(c)(2)(C)) averaged over each consecutive threeyear period after November 15, 1996, until the attainment date. Under the new attainment date, attainment must be achieved as expeditiously as practicable but no later than November 15, 2005.

Under the schedule for submittal of the new SIP, the rateof progress plans for the 1999 and 2002 milestone years will be due well after the November 15, 1999, and November 15, 2002, milestone dates. If sufficient actual reductions occurring by the November 15, 1999, and November 15, 2002, milestone dates do not now exist, then Texas can only get reductions after the two milestone dates because, at this point, the State does not have the ability to require additional reductions for a period that has already passed. The passing of the deadlines does not relieve Texas from the requirement to achieve the 18 percent reduction in emissions, but simply means that the 18 percent reduction must be achieved as expeditiously as practicable but no later than November 15, 2005.

The approved SIP for the BPA area contains measures that generate additional benefits after November 15, 1996. Such measures include reduction requirements on large sources of NOX.

As discussed elsewhere in this document in the section titled ``What is the Relationship Between MOBILE6 and the Post1999 Rateof Progress,'' the CAA specifies the emissions ``baseline'' from which each emission reduction milestone is calculated. Section 182(c)(2)(B) states that the reductions must be achieved ``from the baseline emissions described in subsection (b)(1)(B).'' This baseline value is termed the ``1990 adjusted base year inventory.'' Section 182(b)(1)(B) defines baseline emissions (for purposes of calculating each milestone VOC/NOX emission reduction) as ``the total amount of actual VOC or NOX emissions from all anthropogenic sources in the area during the calendar year of enactment'' and excludes from the [[Page 16488]]
baseline the emissions that would be eliminated by certain specified Federal programs and certain changes to state I/M and RACT rules.\9\ The 1990 adjusted base year inventory must be recalculated relative to each milestone and attainment date because the emission reductions associated with the FMVCP increase each year due to fleet turnover.\10\ \9\ These are the 1990 FMVCP, Phase 2 RVP, and the I/M and RACT fixups.
\10\ See U.S. EPA, (1994), Guidance on the Post1996 Rateof Progress Plan (RPP) and Attainment Demonstration, EPA452/R93015 (Corrected version of February 18, 1994). An electronic copy may be found on EPA's web site at http://www.epa.gov/ttn/oarpg/t1pgm.html (file name: ``post962.zip'').

Therefore, since there are federal and state rules requiring reductions after November 15, 1996, EPA concludes that the BPA area has already implemented measures creditable toward the 1999 and 2002 rate ofprogress milestones. However, we are not able to conclude that the area has sufficient measures to achieve the required 9 percent reduction by November 15, 1999, and an additional 9 percent reduction by November 15, 2002, in the absence of the rateofprogress plans for both the 1999 and 2002 milestone years that document the calculations of the 1999 and 2002 target levels of emissions, account for expected growth in emissions related activities, and contain the requisite demonstration that sufficient creditable reductions have or were projected to occur by November 15, 1999, and November 15, 2002, respectively. We have insufficient data concerning what the levels of reductions would have been in the area by 1999 and 2002, since we do not know what the 1990 adjusted base year inventory for 1996, 1999, and 2002 will be or the projected emissions growth for the periods of November 15, 1996, through November 15, 1999 and November 15, 1999, through November 15, 2002. Nor do we have sufficient information to allow us to determine what will be an expeditiously as practicable date for achievement of this post1996 18 percent rateofprogress requirement.

EPA finds that the 1999 and 2002 rateofprogress requirements are that Texas must submit a rateofprogress plan that demonstrates that the SIP has sufficient measures to achieve the required 18 percent reductions by a date as expeditiously as practicable.\11\ This approach was recently upheld by the United States Court of Appeals for the District of Columbia Circuit in Sierra Club v. EPA, DC. Cir. No. 03 1084 (Feb. 3, 2004), slip opinion at page 22 note 11. Texas must identify sufficient data and show why they meet the ``as expeditiously as practicable'' requirement. Such SIP revision will have to demonstrate that any date after November 15, 1999, by which the 1999 9 percent ROP reduction is achieved, as well as any date after November 15, 2002, by which the first post1999 9 percent ROP reduction is achieved, is as expeditious as practicable.
\11\ EPA believes that such date cannot be any later than November 15, 2005.

B. 2005 RateofProgress

There is no change to the date by which the 20032005 9 percent increment of the rateofprogress must be achieved. If the currently adopted and approved SIP measures and the current suite of Federal measures will not achieve the required rateofprogress reductions, we believe the State has sufficient time to adopt and implement measures to achieve the required reductions in the BPA area by November 15, 2005.
C. Contingency For Failure To Achieve RateofProgress by November 15, 1999 and November 15, 2002

The contingency measures' plan must identify specific measures to be undertaken if the area fails to meet any applicable milestone, to make rateofprogress, or to attain the NAAQS. With respect to the November 15, 1999, and November 15, 2002, milestones, the EPA believes that the contingency plan will need to account for any adjustment to the milestone dates.

With this final action determining that BPA has failed to attain the standard by November 15, 1996, the presentlyapproved 1996 ROP/ attainment contingency plan is automatically invoked. (See 63 FR 6659 for the contingency measures.) Therefore, the State is required to ``backfill'' these contingency measures. Since the BPA area did not attain by the moderate area attainment date, and in order to fulfill the contingency measures' plan requirements of sections 172(c)(9) and 182(c)(9) of the CAA, implementation of the failuretoattain contingency measures' plan in the current SIP is triggered automatically upon the effective date of this Final rule. Further, Texas is required to submit a revision to the SIP containing additional contingency measures to meet post19962005 ROP requirements and for failure to attain by the 2005 attainment date. See 57 FR 13498, 13511 (1992).

XIII. What Are the Impacts on the Title V Program?

In accordance with a serious classification, the major stationary source threshold will now be lower than it was as a moderate classification. Consequently, the State's Title V operating permits program regulations need to cover existing sources that are now subject to the lower major stationary source threshold of serious (50 tons per year for volatile organic compounds (VOCs) and nitrogen oxide compounds (NOX)). Any newly major stationary sources must submit a timely Title V permit application. ``A timely application for a source applying for a part 70 permit for the first time is one that is submitted within 12 months after the source becomes subject to the permit program or on or before such earlier date as the permitting authority may establish.'' See 40 CFR 70.5(a)(1). The 12 month (or an earlier date set by the applicable permitting authority) time period to submit a timely application will commence on the effective date of this reclassification action.
XIV. What Comments Were Received on the Supplemental Proposal, and How Has the EPA Responded to Those?

EPA received comments from the public on the Notice of Supplemental Proposed Rulemaking (NPR) published on June 19, 2003 (66 FR 36756). Comments were received from: South East Texas Regional Planning Commission; Clean Air and Water, Inc.; Orange County Judge, Carl K. Thibodeaux; Goodyear Tire and Rubber Company; Nederland Economic Development Corp.; City of Orange; Bridge City Chamber of Commerce; City of Lumberton; City of Vidor; City of Nederland; City of West Orange; Greater Orange Area Chamber of Commerce; City of Bridge City; City of Beaumont; Greater Port Arthur Chamber of Commerce; City of Port Neches; Beaumont Chamber of Commerce; City of Port Arthur; Golden Triangle Business Roundtable; Jefferson County Judge Carl R. Griffith, Jr.; City of Pinehurst; Southeast Texas Plant Managers' Forum; Texas Commission on Environmental Quality; A joint letter from Sierra Club, Clean Air and Water, Inc., and Community InPowerment Development Association; and twelve individuals.

The following discussion summarizes and responds to relevant comments.
A. Comments in Support of Option 1: About Half of Comments From Private Citizens Supported Reclassification to Severe, Including Comment Letters From Two of the Three Litigants in the 5th Circuit Sierra Club v. EPA Court Case

The following summarizes these comments and EPA's responses. [[Page 16489]]

Comment 1: Commenters believe that the air must be cleaned up and that the EPA and industry should take the steps necessary to protect the life, health, welfare, safety and environment for citizens. They argued that classification to severe is required by the CAA in this circumstance and is long overdue. More monitoring, better regulations, and specific measures required for BPA will protect the public.

Response 1: The EPA agrees that it is necessary to reclassify the BPA area to ensure that the court ruling regarding our extension of the BPA attainment date based upon the Transport Policy is adequately addressed. We do not, however, agree that it is necessary to reclassify the area as severe to ensure the BPA area attains in the most timely manner. Option 1 or Option 2 both result in attainment as expeditiously as practicable but no later than November 2005. Therefore, as explained in later comments we believe that the choice of Option 2 will yield air quality that complies with the NAAQS for ozone as expeditiously as Option 1.

Comment 2: Some of the commenters voiced skepticism that there is a HG transport problem and believe the pollution problem is created within the BPA area. Others commented that the State must account for and overcome problems caused by intrastate air pollution. Texas has the duty under the Act to ensure that its overall statewide SIP (i.e., the amalgamation of regional and area SIPs) quantifies and compensates, through additional emissions reductions, for the effects of upwind areas' air pollution on downwind areas, as the State explains is one reason compromising the BPA area's ability to demonstrate attainment.

Response 2: The Court's December 11, 2002, decision invalidated the EPA's application of the Transport Policy to the BPA area and Texas' ability to rely on it. As a result, the State will need to take whatever measures are required for the BPA area to attain no later than November 15, 2005. This will include measures to address any transport from the HG area and any measures required to address the local sources in the BPA area. Since the EPA believes that both situations, local emissions or transport from the HG area, can result in exceedances in the BPA area, we will expect the State's attainment modeling demonstration to encompass both types of events.

Comment 3: The BPA area's emissions inventory must be updated to reflect current actual emissions, including incorporation of MOBILE6 emissions factors, consideration of the effect of the failure of the heavy duty diesel engine manufacturers' settlement agreement to accomplish the anticipated levels of diesel engine retrofits (EMA v. EPA, DC Cir. Nos. 011129 and 021080), the State's awareness of considerably higher actual emissions from many refineries and chemical plants from malfunctions and other conditions. Moreover, the EPA should identify in this final rulemaking BPA's planning inventory, versus the ``overall'' emissions inventory described in the Supplemental Proposal notice.

Response 3: The EPA agrees that the required attainment demonstration SIP revision and the revised MVEB, as well as the ROP plans, must incorporate MOBILE6 emissions factors. Further, the State must consider the impact of revised or current information, e.g., the most accurate mobile source emissions estimates (including any variation due to underestimations such as those for the longhaul truck reflashing), present growth predictions, effectiveness of control measures, etc., when developing the revised SIP for BPA. Whatever data is presently available to the State concerning the impact of upset/ malfunctions and other conditions on the emissions from refineries and chemical plants must also be addressed.

The motor vehicle emissions budgets submitted by the State with the BPA transport attainment demonstration are no longer valid as they were based on a November 15, 2007, attainment date. Therefore, the budgets submitted for the new SIP must be prepared using the MOBILE6 emissions factor model and the revised SIP must contain budgets based on MOBILE6 modeling. The Clean Air Act section 172(c)(3) and 40 CFR 51.112(a)(1) require that the inventories and control measures be based on the most current information available when a SIP is developed.

We agree that the planning inventory the State uses in developing the required SIP revision must include all sources of emissions, including biogenic emissions. In our supplemental notice, we did not mean to imply the figures in our supplemental notice were acceptable for SIP planning purposes. Our comment accurate estimates of biogenic emissions generally are not available, and that rough estimates typically relied on can inflate and distort SIP emissions inventories, is not relevant to this rulemaking. Texas will need to incorporate the best available estimate of biogenic emissions in its revised SIP. There will be an opportunity for the public to comment on the State's estimates during the State's comment period. There will also be the opportunity to comment on the EPA's action approving or disapproving the State's Plan including any emissions estimates.

Comment 4: The EPA failed adequately to explain the basis for its RACM conclusion in the rulemaking. The prior RACM analysis is now stale and must be completely revised, both to address changed circumstances (i.e., newly available control measures) and the advanced attainment date and concomitant additional emissions reductions.

Response 4: We agree that the previous RACM analysis must be revised. As a result of the Fifth Circuit's decision, the RACM analysis associated with the State's 2007 attainment date demonstration is no longer applicable since it was based on a 2007 attainment date. A new RACM analysis will be required to be submitted for the BPA area that addresses the 2005 attainment date and any other changed circumstances.

The Court affirmed the portion of our May 15, 2001, final action that treats as potential RACMs only those measures that would advance the attainment date and that considers implementation costs when rejecting certain control. The Court agreed, however, with the commenters that the EPA failed adequately to explain the basis for its RACM conclusion, and remanded it to EPA. According to the Court's order, the EPA's analysis must: (1) demonstrate an examination of all relevant data; and (2) provide a plausible explanation for the rejection of proposed RACMs including why the measures, individually and in combination, would not advance the BPA area's attainment date.

The State is responsible for performing and submitting a new RACM analysis for EPA use in determining SIP approval. EPA will consider as adequate an RACM analysis by the State containing the factors outlined in the Court's December 11, 2002, ruling, when evaluating the use of RACM in the SIP approval process.

Comment 5: A Commenter asserted that Texas must expedite its one hour ozone SIP submittal to accomplish improved air quality as expeditiously as practicable. The commenter contended that if EPA had acted legally, there would already be an approved SIP with implementation of control measures. It appears that rather than expediting revision of the SIP, Texas is prolonging the period of unhealthful air quality by delaying action to identify and adopt necessary further controls to improve the area's air quality to meet the one hour ozone standard.

Response 5: In this final action, the EPA finds a one year deadline is appropriate for the State of Texas to
[[Page 16490]]
submit the required revised SIP, a new MVEB, and a reanalysis of RACM. The State has already started efforts for reanalysis using MOBILE6, initiated other emission inventory and modeling activities, and intends to propose the new SIP this Spring, and the EPA believes that on or before one year after the effective date of this rule is as expeditiously as practicable and a reasonable time for submittal. Moreover, many of the more stringent NOX control measures in the current SIP were implemented in 2003. Therefore, local controls are continuing to be imposed in the area to reduce the ozone concentration levels.

Comment 6: A commenter urged that EPA must not further delay issuing a SIP call for a revised one hour ozone SIP in accordance with the Court's direction. The 8hour ozone standard will require a separate planning effort.

Response 6: Today's final action serves a function similar to that of a SIP call in that it requires a revised 1hour ozone SIP that must be submitted within one year of the effective date of this final action. Since we have not yet promulgated a final rule for implementation of the 8hour ozone standard, we cannot speculate whether a state may combine its 1hour ozone serious area CAA requirements with an 8hour ozone planning effort. Please see Section XIV, B, response to comment 5 for further information.

Comment 7: A commenter urges EPA to impose offset sanctions as a result of the inadequacy of the BPA area's submitted SIP.

Response 7: EPA does not believe that discretionary sanctions are appropriate in this instance where the State has made submissions in reliance on EPA policies, and mandatory sanctions would not be imposed unless EPA disapproves a SIP submission. New SIP submission schedules for the requirements imposed as a result of the failure to attain determination for Beaumont, are just now being made. The State should have an opportunity to meet these new obligations before sanctions are imposed.

Comment 8: A commenter argues that Congress provided EPA with authority to require the BPA SIP to ``include such additional measures as the Administrator may reasonably prescribe.'' 42 U.S.C. 7509(d)(2). The commenter asserts that EPA should require, among other things, control of flaring. See, for example, Santa Barbara County Air Pollution Control District Rule 359.

Response 8: As long as the State submits a SIP that demonstrates attainment of the 1hour ozone standard in the BPA area as
expeditiously as practicable but no later than November 15, 2005, and meets all of the Act's requirements, Texas may select whatever mix of control measures it desires. Union Elec. Co. v. EPA, 427 U.S. 246 (1976). With this rule, it is now the responsibility of the State of Texas to identify and adopt measures to enable attainment as expeditiously as practicable but no later than November 15, 2005, and meet the other requirements of the Act, including the serious area classification requirements, the requirements for the rate of progress, and RACM, contingency measures plan, demonstrating attainment as expeditiously as practicable, etc. EPA does not have the authority to require specific measures for the State at this time. If control of flares from source categories is not required for expeditious attainment or to meet RACT, the State must evaluate whether control of flares from source categories is an RACM. It is the role of the State, not EPA, to be the first to identify specific measures consistent with the BPA area's particular emissions inventory. The EPA will provide assistance and guidance to Texas in this effort.

Comment 9: Commenters question whether Texas has already implemented measures creditable toward the 1999 and 2002 ROP milestones. Texas must make a detailed showing of what control measures are creditable for past ROP obligations, and for exactly what quantity of emissions reductions.

Response 9: EPA agrees that Texas must submit 1999 and 2002 ROP plans that contain specifics and details to demonstrate clearly whether previously implemented control measures meet these ROP obligations. See Section XII for our discussion on these requirements.
B. Comments in Support of Option 2: The Remaining Letters From Private Citizens, and 23 other Letters From BPA Area Cities, Judges, Chambers of Commerce, Business/Industry Groups, Metropolitan Planning Organizations, and the Texas Commission on Environmental Quality (TCEQ) Commented in Opposition to Option 1

These comments are summarized and discussed here.

Comment 1: Many commenters supported Option 2, a reclassification to serious with an attainment date of November 15, 2005. Some of the commenters stated that the area should not be reclassified at all. Commenters argued that extensive emission reduction activities have already been implemented, and that since 1972 there has been a clear downward trend in ambient ozone measurements for the BPA area.

Response 1: The EPA is required by the Fifth Circuit's decision to make a determination as to whether BPA attained by November 15, 1996. Since the BPA area failed to attain by 1996, BPA cannot remain classified as ``moderate.''

While there has been general improvement in the ozone design values throughout the years, the area has yet to attain the one hour NAAQS. This final rule is making a final determination that the BPA area failed to attain by November 15, 1996, thereby reclassifying by operation of law the BPA area to serious, and is establishing an attainment date of as expeditiously as practicable but no later than November 15, 2005.

Comment 2: EPA is authorized to adopt Option 2 and should do so because it is fair. Commenters contended that because EPA did not timely issue a determination for attainment, it is empowered to extend the attainment date when it reclassifies an area. Commenters also asserted that a second reclassification to severe would unfairly punish an area, whose air quality has improved over the years. A commenter argued that the Clean Air Act contemplates that states will have a prospective opportunity to bring reclassified areas into attainment. A petitioner stated that ``where EPA's failure to meet its own deadline impacts the lead time Congress intended to provide states to obtain the standard after reclassification, then EPA may also extend the attainment date.''

Response 2: EPA believes that a further determination for failure to attain by November 25, 1999 and reclassification by operation of law to severe is not appropriate in light of the specific history, facts, and circumstances for the BPA area. Option 2 is fair for the unique circumstances presented by the BPA area. From discussions we believe that a unique plan will be developed for the BPA area that will still expeditiously attain the standard yet not unduly ``punish'' the area.

Comment 3: The BPA area should not be reclassified as severe, as this classification would create unnecessary economic burdens for the BPA area, as well as being unfair to the BPA area.

Response 3: Since the BPA area is not being reclassified to severe, the perceived unnecessary economic burdens will not occur. Nevertheless, under the provisions of the CAA the EPA does not have the authority to consider any potential economic
[[Page 16491]]
consequences arising from a reclassification for nonattainment of an NAAQS. Under section 181(b)(2)(A), the attainment determination is made solely on the basis of air quality data, and any reclassification is by operation of law. If an area is reclassified, the more stringent requirements apply irrespectively of economic considerations.

It is, however, appropriate for a state to consider specific economic impacts in meeting the new requirements and in developing specific regulatory requirements for specific sources. For example, an entity proposed to be regulated by Texas to meet RACT, may seek a case specific RACT determination by the State, based on economic or technical hardship. Texas may also consider implementation costs when rejecting certain control measures in its proposed RACM analysis. This consideration for RACM was specifically upheld in the Court's ruling. EPA must approve a SIP revision if it meets the requirements of the Act, even if it is more stringent. Union Elec. Co. v. EPA, 427 U.S. 246 (1976). Additionally, actions (such as the approval of a SIP revision) that merely approve state law as meeting federal requirements and impose no additional requirements beyond those imposed by state law, are not subject to economic impact analysis under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Such consideration is up to the state under applicable state administrative procedure laws. Details on the State's assessments of financial impact flowing from the required new SIP revision will be found in the Texas proposed SIP documents, and must be made available by Texas to the public when Texas conducts its public participation.

Comment 4: EPA should waive Texas' obligation to submit a 1hour attainment demonstration SIP for BPA. This would be consistent with options EPA proposed in the June 2, 2003 Federal Register for transitioning from the 1hour to the 8hour ozone standard and would allow Texas to focus its limited air quality planning resources on the more protective 8hour standard. If EPA requires Texas to submit a 1 hour attainment demonstration SIP, the SIP should be due no earlier than one year after EPA's final reclassification action.

Response 4: The June 2, 2003 Federal Register proposal notice for transitioning from the 1hour to the 8hour ozone standard solicits comment on whether to retain the 1hour ozone attainment demonstration requirement for areas like BPA.

The June 2, 2003 Federal Register notice for transitioning from the 1hour to the 8hour ozone standard is only a proposal. The EPA presently has no authority to waive the State's obligation to submit a 1hour SIP and to meet the CAA requirements to attain the 1hour ozone NAAQS. It is currently the State's responsibility to perform planning and SIP activities and submittals to meet the 1hour NAAQS for ozone. EPA is in the process of evaluating comments on its June 2 proposal, and will address these issues in its final action.

Comment 5: A number of the commenters state that pollutants transported into Southeast Texas from the HG area, which cannot be locally controlled, are prohibiting the BPA area from attaining. Commenters believe that the BPA area already has sufficient controls in place, or that will take effect shortly (e.g., 44% NOX controls), and due to transport it is unlikely that any new local control measures would lead to more expeditious attainment. They request the EPA to validate the transport of air from the HG area.

Response 5: While EPA agrees that the BPA area is affected by transport from outside the area by the upwind HG area, the U.S. Court of Appeals for the Fifth Circuit ruled on December 11, 2002 that EPA is precluded from extending the BPA area's attainment date using the Transport Policy. At the time the State's current SIP revision was submitted, the Transport Policy was used to analyze the SIP revisions, and EPA believes that Texas demonstrated that during some exceedances in the BPA area, ozone levels are affected by emissions from the HG area, and that the HG area emissions affect BPA's ability to meet attainment of the 1hour ozone standard. The Court's ruling, however, invalidated the EPA's interpretation of the Act reflected in the policy by which an attainment date extension based on transport was granted to the BPA area.
XV. EPA Action

EPA is taking the following actions:
We are withdrawing our final action that extended the attainment date to November 15, 2007, and approved the transport demonstration (66 FR 26914).
We are withdrawing our final approval of BPA's 2007 attainment demonstration SIP, the Mobile Vehicle Emissions Budget (MVEB), the midcourse review commitment (MCR), and our finding that BPA implemented all Reasonable Available Control Measures (RACM). Pursuant to section 181 (b), we find that BPA has failed to attain the 1hour ozone national ambient air quality standard (NAAQS or standard) by November 15, 1996, the attainment date for moderate nonattainment areas set forth in the Act.
The area is reclassified by operation of law as a serious 1hour ozone nonattainment area,
We are establishing an attainment date of as expeditiously as practicable but no later than November 15, 2005. The contingency measures plan for failure to attain is triggered upon the effective date of this final action. The State of Texas must backfill this contingency measures plan for failure to attain.
We are adjusting the dates by which the area must meet the 1999 and 2002 rateofprogress (ROP) requirements and adjusting contingency measure requirements as they relate to the ROP requirements.
The State of Texas is no longer required to submit an MCR by May 1, 2004.
The State of Texas is to submit the required revised SIP, a new MVEB, and a reanalysis of RACM, on or before one year after the effective date of this Final action.
XVI. Statutory and Executive Order Reviews

A. Executive Order 12866, Regulatory Planning and Review

Under Executive Order 12866 (58 FR 51735, October 4, 1993), EPA is required to determine whether regulatory actions are significant and therefore should be subject to Office of Management and Budget (OMB) review, economic analysis, and the requirements of the Executive Order. The Executive Order defines a ``significant regulatory action'' as one that is likely to result in a rule that may meet at least one of the four criteria identified in section 3(f), including, under paragraph (1), that the rule may ``have an annual effect on the economy of $100 million or more or adversely affect, in a material way, the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or state, local or tribal governments or communities.''

The Agency has determined that findings of nonattainment would result in none of the effects identified in section 3(f) of the Executive Order. Under section 181(b)(2) of the CAA, determinations of nonattainment are based upon air quality considerations and the resulting reclassifications must occur by operation of law. They do not, in and of themselves, impose any new requirements on any sectors of the economy. In addition, because the statutory requirements are clearly defined with respect to the differently
[[Page 16492]]
classified areas, and because those requirements are automatically triggered by the resulting classifications that, in turn, are triggered by air quality values, determinations of nonattainment and reclassifications cannot be said to impose a materially adverse impact on state, local, or tribal governments or communities.

B. National Technology Transfer and Advancement Act

Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104113, section 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary consensus standards.

This final action to reclassify the BPA area as a serious ozone nonattainment area and to adjust applicable deadlines does not involve technical standards. Therefore, EPA did not consider the use of any voluntary consensus standards.
