Approval and Promulgation of Air Quality Implementation Plans;
California; Determination of Attainment of the 1-Hour Ozone Standard for the Ventura County Area
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
SUMMARY: On April 15, 2009, the California Air Resources Board (CARB) requested that EPA find that the Ventura County ozone nonattainment area has attained the revoked 1-hour ozone National Ambient Air Quality
Standard (NAAQS). After a review of this submission and of the relevant monitoring data, EPA is making such a finding.
Because the area has attained the 1-hour standard by the applicable attainment date, the area is not subject to the requirement to implement contingency measures for failure to attain the standard by its attainment date. In addition, EPA finds that the area is not subject to the Clean Air Act penalty fee requirements for severe and extreme ozone nonattainment areas that have not attained the 1-hour standard by the applicable attainment date.
DATES: This rule is effective on July 27, 2009 without further notice, unless EPA receives adverse comments by June 26, 2009. If we receive such comments, we will publish a timely withdrawal in the Federal
Register to notify the public that this direct final rule does not take effect.

What Is the Background for This Action?
Under section 107(d)(1)(C) of the Clean Air Act (CAA), the Ventura
County, California area was designated nonattainment for the 1-hour ozone NAAQS by operation of law upon enactment of the 1990 CAA
Amendments. Under section 181(a) of the CAA, each ozone area designated nonattainment under section 107(d) was also classified by operation of law as ``marginal,'' ``moderate,'' ``serious,'' ``severe-15,''
``severe-17,'' or ``extreme,'' depending on the severity of the area's air quality problem and the number of years to reach attainment from the time of the CAA Amendments.
The ozone design value for an area, which characterizes the severity of the air quality problem, is represented by the highest ozone design value at any of the individual ozone monitoring sites in the area. Table 1 in section 181(a) of the CAA provides the design value ranges for each nonattainment classification. Ozone nonattainment areas with design values between 0.180 parts per million (ppm) and 0.190 ppm for the three-year period, 1987-1989, were classified as severe-15. Because the Ventura County, California area's 1988 ozone design value fell between 0.180 and 0.190 ppm, this area was classified as severe-15 nonattainment for the 1-hour ozone NAAQS. These nonattainment designations and classifications were codified in title 40 of the Code of Federal Regulations (CFR) part 81 (see 56 FR 56994,
November 6, 1991).
Under section 182(c) of the CAA, states containing areas that were classified as severe-15 nonattainment were required to submit State
Implementation Plans (SIPs) to provide for certain emission controls, to show progress toward attainment, and to provide for attainment of the ozone NAAQS as expeditiously as practicable, but no later than
November 15, 2005. The State of California included plans for bringing
Ventura County into attainment with the 1-hour ozone standard in their 1994 State Implementation Plan (SIP) revision that EPA approved on
January 8, 1997 (62 FR 1150). Specifically, EPA approved the Ventura 1994 ozone SIP with respect to the Act's requirements for emission inventories, control measures, modeling, demonstrations of 15% Rate of
Progress (ROP), post-1996 ROP and attainment of the 1-hour ozone standard.
In 1997, EPA adopted a new 8-hour ozone NAAQS. One of the implementation rules for the standard, referred to as the Phase 1
Implementation Rule, was published on April 30, 2004 (69 FR 23951), and addressed how requirements that applied in an area for the 1-hour ozone
NAAQS would apply in the transition from the 1-hour standard to the 8- hour standard. Challenges to this rule were decided in South Coast Air
Quality Management District v. EPA, 472 F.3d 882 (DC Cir. 2006)
(SCAQMD), rehearing denied 489 F.3d 1245, which we considered in this action.

How Does the SCAQMD Decision Regarding EPA's 8-Hour Phase 1 Ozone
Implementation Rule Affect This Action?
On December 22, 2006, the U.S. Court of Appeals for the District of
Columbia Circuit vacated EPA's Phase 1 Implementation Rule for the 8- hour Ozone Standard. SCAQMD v. EPA, 472 F.3d 882. On June 8, 2007, in response to several petitions for clarification and rehearing, the DC
Circuit clarified that the Phase 1 Rule was vacated only with regard to those parts of the rule that had been successfully challenged. 489 F.3d 1245. With respect to the challenges to the anti-backsliding provisions of the rule, the Court vacated three provisions that would have allowed
States to remove from the SIP or to not adopt three SIP obligations related to the 1-hour ozone standard once the 1-hour ozone standard was revoked: (1) Nonattainment area new source review (NSR) requirements based on an area's 1-hour nonattainment classification; (2) section 185 penalty fees for severe or extreme 1-hour ozone nonattainment areas that fail to attain the 1-hour ozone standard by the 1-hour ozone attainment date; and (3) measures to be implemented pursuant to section 172(c)(9) or 182(c)(9) of the Act, on the contingency of an area not making reasonable further progress (RFP) toward attainment of the 1- hour NAAQS or for failure to attain that NAAQS. The Court clarified that 1-hour ozone conformity determinations are not required for anti- backsliding purposes.
Thus, the provisions waiving these three requirements, which were specified in 40 CFR 51.905(e), were vacated by the Court. As a result of the vacatur, States must continue to meet the obligations for 1-hour ozone NSR; 1-hour ozone contingency measures; and, for severe and extreme areas, the obligations related to a section 185 fee program.
EPA has issued a proposed rule that would remove the vacated provisions of 40 CFR 51.905(e) and that addresses treatment of contingency measures for failure to attain or make reasonable further progress toward attainment of the 1-hour standard. See 74 FR 2936, January 16, 2009 (proposed rule); 74 FR 7027, February 12, 2009 (notice of public hearing and extension of comment period). EPA is developing a proposed rule to address treatment of 1-hour NSR and section 185 fees for failure to attain the 1-hour standard.
We address below how the 1-hour ozone obligations that currently continue to apply as a result of the Court's vacatur of the waiver provisions are treated where EPA makes a determination that the area attained the 1-hour ozone standard by its attainment date.

Attainment Finding
In 1991, the Ventura County, California area was classified as severe-15 for the 1-hour ozone NAAQS. An area is considered to have attained the 1-hour ozone NAAQS if there are no violations of the standard, as determined in accordance with the regulation codified at 40 CFR 50.9 and the related regulatory appendix, 40 CFR Part 50,
Appendix H, based on three consecutive calendar years of complete, quality-assured monitoring data. A violation occurs when the ozone air quality monitoring data show greater than one (1.0) average expected
Page 25155
exceedance per year at any site in the area. An exceedance occurs when the maximum hourly ozone concentration during any day exceeds 0.124 ppm. In accordance with 40 CFR part 58, the data should be collected and quality-assured and recorded in the Air Quality System so that they are available to the public for review.
The finding of attainment for the Ventura County, California area is based on an analysis of 1-hour ozone air quality data from 2003- 2005. Table 1 summarizes these data.

What Action Is EPA Taking?
EPA is determining that the Ventura County, California area attained the 1-hour ozone standard by its attainment date, November 15, 2005.
The data summary presented in Table 1 demonstrates that there was less than one expected exceedance of the 1-hour ozone standard in
Ventura County averaged over the 3 years 2003 to 2005. Because the area attained the 1-hour standard by the applicable attainment date, the area is not subject to the requirement to implement contingency measures for failure to attain the standard by its attainment date. As such, even if the area subsequently lapses into nonattainment, it would not be required to implement the contingency measures for failure to attain the standard by its attainment date.
Section 185(a) of the CAA states that a severe or extreme ozone nonattainment area must implement a program to impose fees on certain stationary sources of air pollution if the area ``has failed to attain the national primary ambient air quality standard for ozone by the applicable attainment date.'' Consequently, if such an area has attained the standard as of its applicable attainment date, even if it subsequently lapses into nonattainment, the area would not be required to implement a section 185 fee program. Because EPA is determining that the Ventura County, California area attained the 1-hour standard by its applicable attainment date, we conclude that the area is not subject to the requirements of section 185 for the 1-hour standard. Accordingly, we also determine that the State is not required to submit a SIP under
Section 182(d)(3) of the CAA to implement a section 185 program for the 1-hour standard in this area.

Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA 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 CAA. 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
Page 25156
substantial number of small entities under the Regulatory Flexibility
Act (5 U.S.C. 601 et seq.);
Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4);
Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
Is not subject to requirements of Section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
In addition, this rule does not have tribal implications as specified by Executive Order 13175 (59 FR 22951, 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.
