Approval and Promulgation of Implementation Plans; Arizona; Update to Stage II Gasoline Vapor Recovery Program; Change in the Definition of “Gasoline” To Exclude “E85”

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule.

SUMMARY:

Under the Clean Air Act, EPA is taking final action to approve certain revisions to the Arizona State Implementation Plan submitted by the Arizona Department of Environmental Quality. These revisions concern amendments to the statutory and regulatory provisions adopted by the State of Arizona to regulate volatile organic compound emissions from the transfer of gasoline from storage tanks to motor vehicle fuel tanks at gasoline dispensing sites, i.e., stage II vapor recovery. The revisions also amend the definition of “gasoline” to explicitly exclude E85 and thereby amend the requirements for fuels available for use in the Phoenix metropolitan area as well as the requirements for vapor recovery. In approving the revisions, EPA is taking final action to waive the statutory stage II vapor recovery requirements at E85 dispensing pumps within the Phoenix metropolitan area. Lastly, EPA is taking final action to correct an EPA rulemaking that approved a previous version of the Arizona rules regulating these sources and to thereby identify the appropriate regulatory agency and specific rules that were previously approved and incorporated by reference into the Arizona State Implementation Plan.

DATES:

Effective Date: This rule is effective on July 13, 2012.

I. EPA's Proposed Action

A. The State's Submittal

On October 3, 2011 (76 FR 61062), we proposed to approve a revision to the Arizona State Implementation Plan (SIP) submitted to EPA on September 21, 2009 by the Arizona Department of Environmental Quality (ADEQ). The purpose of the SIP revision is to update the gasoline vapor recovery program that was originally submitted and approved by EPA in 1994 to meet certain applicable requirements of the Clean Air Act, as amended in 1990 (CAA or “Act”). The specific revisions include statutory provisions and administrative rules regulating the emissions of volatile organic compounds (VOC) due to the transfer of gasoline from storage tanks (typically underground) to motor vehicle fuel tanks at gasoline stations in the Phoenix metropolitan area. The statutory provisions and administrative rules are contained in enclosures 3 and 4 of ADEQ's September 21, 2009 SIP revision submittal package.

ADEQ's submittal represents an update to the stage II requirements but is comprehensive in that the submitted statutory and regulatory provisions also address general requirements related to stage I vapor recovery. While ADEQ's submittal relates almost entirely to the State's vapor recovery program, it also amends the State's fuels program by amending the definition of the term “gasoline” to exclude “E85,” a change that affects both the gasoline fuels program established for the Phoenix metropolitan area and the stage II vapor recovery program because both programs now rely on that particular definition. In our October 3, 2011 proposed rule, we concluded that ADEQ's September 21, 2009 SIP revision submittal contains adequate documentation of public notice, opportunity for comment, and a public hearing on the proposed SIP revision (see enclosure 5 of the submittal) and that the public participation materials submitted by ADEQ demonstrate compliance with the procedural requirements set forth in section 110(l) of the CAA.

Table 1 lists the statutory provisions, and Table 2 lists the administrative rules, that were submitted by ADEQ on September 21, 2009 and that we are approving in today's action.

Under Arizona law, the principal stage II vapor recovery requirements are found in Arizona Revised Statutes (ARS) section 41-2132 (“Stage I and stage II vapor recovery systems”), which requires gasoline dispensing sites to be equipped with a stage II vapor collection system within “an ozone nonattainment area designated as moderate, serious, severe or extreme by the United States environmental protection agency under § 107(d) of the clean air act, area A or other geographical area * * *.” ARS section 41-2132(C). “Area A” is defined in ARS section 49-541 and it includes all of the metropolitan Phoenix former 1-hour ozone nonattainment area plus additional areas in Maricopa County to the north, east, and west, as well as small portions of Yavapai County and Pinal County.

ARS 41-2132 also provides an exemption for gasoline dispensing sites with a throughput of less than 10,000 gallons per month or less than 50,000 gallons per month in the case of an independent small business marketer as defined in section 324 of the CAA, and for gasoline dispensing sites that are located on a manufacturer's proving ground. ARS 41-2133 sets forth certain compliance schedules related to the stage II vapor recovery requirements in ARS 41-2132.

The stage II vapor recovery requirements in ARS 41-2132 rely upon the definitions of certain terms, such as “gasoline,” “stage II vapor collection system,” and “E85,” among others, which are codified in ARS sections 41-2015, 41-2121, and 41-2131, and ADEQ included the relevant definitions, along with ARS sections 41-2132 and 41-2133, in the SIP revision submittal dated September 21, 2009. See table 1 of this document. The definition of “gasoline,” which is codified in paragraph (5) of ARS 41-2121, specifically excludes “diesel fuel” and “E85.”

ARS section 41-2132(G) directs the Arizona Department of Weights and Measures (ADWM) to adopt rules that establish standards for the installation and operation of stage I and stage II vapor recovery systems. In 1994, EPA approved an earlier version of ADWM's rules for stage II vapor recovery. See 59 FR 54521 (November 1, 1994). Since then, in addition to renumbering and recodifying the rules, ADWM has amended the vapor recovery rules to delete, modify, and add certain definitions; to approve use of certain new test procedures developed by the California Air Resources Board (CARB); to include general requirements for stage I vapor recovery systems; to add exemptions for motor raceways, motor vehicle proving grounds, and marine and aircraft refueling facilities; to clarify and expand application requirements; and to enhance compliance-related provisions.

ADWM's rules for such systems are now codified at title 20, chapter 2, article 9 (“Gasoline Vapor Recovery”), of the Arizona Administrative Code (AAC). These rules rely upon certain definitions in AAC, title 20, chapter 2, article 1 (“Administration and Procedures”), section R20-2-101 (“Definitions”). ADEQ submitted these rules and definitions to EPA as part of the stage II SIP revision dated September 21, 2009—see table 2 of this document.

In our October 3, 2011 proposed rule, we also explained that in our 1994 final rule approving an earlier version of ADWM's vapor recovery rules, we made an error in how we codified the stage II vapor recovery rules into the Arizona SIP, and were thus proposing to correct that error. Please see our October 3, 2011 proposed rule at pages 61063 and 61064 for additional information on these topics.

B. Regulatory Context

Under CAA section 182(b)(3), stage II vapor recovery systems are required to be used at larger gasoline dispensing facilities located in Serious, Severe, and Extreme nonattainment areas for ozone. More specifically, the Act specifies that such systems be installed at any facility that dispenses more than 10,000 gallons of gasoline per month, or, in the case of an independent small business marketer (as defined in CAA section 324), any facility that dispenses more than 50,000 gallons of gasoline per month. Based on deadlines established in the Act, within 24 months from the effective date of the initial area designation and classification, states must adopt a stage II program into their SIPs, and the controls must be installed according to specified deadlines following state rule adoption. For existing facilities the installation deadlines depend on the date the facilities were built and the monthly volume of gasoline dispensed. See CAA sections 182(b)(3)(A)-(B), and 324(a)-(c).

However, the CAA provides discretionary authority to the EPA Administrator to, by rule, revise or waive the section 182(b)(3) stage II requirement after the Administrator determines that On-Board Refueling Vapor Recovery (ORVR) is in widespread use throughout the motor vehicle fleet. See CAA section 202(a)(6). ORVR consists of an activated carbon canister installed in the vehicle into which vapors being expelled from the vehicle fuel tanks are forced to flow. There the vapors are captured by the activated carbon in the canister. When the engine is started, the vapors are drawn off of the activated carbon and into the engine where they are burned as fuel. EPA promulgated ORVR standards on April 6, 1994, 59 FR 16262.

EPA first began the phase-in of ORVR by requiring that 40 percent of passenger cars manufactured in model year 1998 be equipped with ORVR. The ORVR requirement for passenger cars was increased to 100 percent by model year 2000. Phase-in continued for other vehicle types and ORVR has been a requirement on virtually all new gasoline-powered motor vehicles (passenger cars, light trucks, and complete heavy-duty gasoline powered vehicles under 10,000 lbs gross vehicle weight rating (GVWR)) sold since model year 2006. See 40 CFR part 86. Currently, ORVR-equipped vehicles comprise approximately 67 percent of the in-service vehicle fleet nationwide, and account for around 76 percent of the vehicle miles traveled (VMT) in the nationwide fleet. The percentage of non-ORVR vehicles and the percentage of VMT driven by those vehicles declines each year as these older vehicles wear out and are removed from service. Since certain vehicles are not required to have ORVR, including motorcycles and incomplete heavy-duty gasoline powered trucks chassis, under current requirements the nationwide motor vehicle fleet would never be entirely equipped with ORVR but these vehicles account for less than 2 percent of national annual highway gasoline consumption.

The CAA anticipates that, over the long-term, ORVR will reduce the benefit from, and the need for, stage II vapor recovery systems at gasoline dispensing sites in ozone nonattainment areas, and as noted above, section 202(a)(6) of the CAA allows EPA to revise or waive the application of stage II vapor recovery requirements for areas classified as Serious, Severe, or Extreme for ozone, as appropriate, after such time as EPA determines that ORVR systems are in widespread use throughout the motor vehicle fleet. CAA section 202(a)(6) does not specify which motor vehicle fleet must be the subject of a widespread use determination before EPA may revise or waive the section 182(b)(3) stage II requirement. Nor does the CAA identify what level of ORVR use in the motor vehicle fleet must be reached before it is “widespread.” To date, EPA has issued two memoranda addressing when ORVR widespread use might be found for particular fleets.

EPA expects the possibility of different rates of implementation of ORVR across different geographic regions and among different types of motor vehicle fleets within any region. Given this, EPA does not believe that CAA section 202(a)(6) must be read narrowly to allow a widespread use determination and waiver of the stage II requirement for a given area or area's fleet only if ORVR use has become widespread through the entire United States, or only if ORVR use has reached a definite level in each area. Rather, EPA believes that section 202(a)(6) allows the Agency to apply the widespread use criterion to either the entire motor vehicle fleet in a State or nonattainment area, or to special segments of the overall fleet for which ORVR use is shown to be sufficiently high, and to base widespread use determinations on differing levels of ORVR use, as appropriate. EPA also believes that the Act allows the Agency to use an area-specific rulemaking approving a SIP revision to issue the section 202(a)(6) waiver for a relevant fleet in a nonattainment area.

One metric that EPA has considered in determining whether ORVR use is widespread within a given motor vehicle fleet considers when VOC emissions resulting from the application of ORVR controls alone equal the VOC emissions when both stage II vapor recovery systems and ORVR controls are used, after accounting for incompatibility excess emissions. The incompatibility excess emissions factor relates to losses in control efficiency when certain types of stage II and ORVR are used together. One metric previously discussed by EPA for widespread use in distinct and unique situations was that widespread use will likely have been reached when the percentage of motor vehicles in service with ORVR, the vehicle miles traveled (VMT) by ORVR-equipped vehicles, or the gasoline dispensed to ORVR-equipped vehicles reaches 95 percent. See the 2006 Page/Oge Memorandum, page 2. Application of the 95 percent criterion could lead to, for example, waiver of stage II vapor recovery requirements at gasoline dispensing sites that exclusively fuel new automobiles at assembly plants and rental cars at rental car facilities given the high percentage (essentially 100%) of ORVR-equipped vehicles associated with such facilities.

Recently, EPA proposed criteria for determining whether ORVR is in “widespread use” for purposes of controlling motor vehicle refueling emissions throughout the motor vehicle fleet. See 76 FR 41731 (July 15, 2011). In EPA's July 15, 2011 action, EPA also proposed criteria that would establish June 30, 2013 as the date on with “widespread use” will occur nationally, and the date on which a nationwide waiver of stage II gasoline vapor recovery systems will be effective.

EPA, after considering public comments, intends to take final action regarding the July 15, 2011 proposal to establish a nationwide date for determining when ORVR is in “widespread use” and for waiving the stage II requirement. In the proposed rule, EPA stated that it intends to provide that individual states may submit SIP revisions that demonstrate that ORVR widespread use has occurred (or will occur) on a date earlier than the date identified in the final rule for areas in their states, and to request that the EPA revise or waive the section 182(b) (3) requirement as it applies to only those areas. See 76 FR at 41733. Consistent with EPA's July 15, 2011 proposal to allow states to submit such SIP revisions, EPA is taking final action today to approve an area-specific revision to the Arizona SIP and to approve a waiver for a specific portion of the motor vehicle fleet, namely flexible fuel vehicles refueled with E85 gasoline blend, in the Phoenix metropolitan area.

As explained in our October 3, 2011 proposed rule, the “Phoenix area,” defined by the Maricopa Association of Governments' (MAGs') urban planning area boundary (but later revised to exclude the Gila River Indian Community at 70 FR 68339 (November 10, 2005)), was classified as a “Moderate” nonattainment area for the 1-hour ozone national ambient air quality standard (NAAQS) and later reclassified as “Serious” for the 1-hour ozone standard. See 56 FR 56694, at 56717 (November 6, 1991) and 62 FR 60001 (November 6, 1997). As noted above, section 182(b)(3) of the Act required States with ozone nonattainment areas such as the Phoenix area to adopt and submit a SIP revision requiring gasoline dispensing facilities to install and operate stage II vapor recovery equipment, and in response, ADEQ submitted the statutory provisions and rules establishing stage II vapor recovery requirements in the Phoenix area. EPA approved the stage II vapor recovery rules as a revision to the Arizona SIP. See 59 FR 54521 (November 1, 1994). We are taking final action today to approve a SIP revision that updates the stage II vapor recovery requirements for the Phoenix metropolitan area and that waives stage II vapor recovery requirements at E85 dispensing pumps.

C. EPA's Evaluation of SIP Submittal and Proposed Action

Relevant Statutes, Rules, Policies, and Guidance

In our October 3, 2011 proposed rule, we explained how we evaluated the statutory provisions and administrative rules that ADEQ submitted to update the Arizona SIP with respect to the stage II vapor recovery program in the Phoenix metropolitan area. To summarize that information, we evaluated ADEQ's stage II vapor recovery SIP update revision based on the Phoenix metropolitan area's designations and classifications for the now-revoked one-hour ozone standard and the current eight-hour ozone standard to ensure Arizona's stage II program complies with section 182(b)(3) of the Act (which is described in section I.B. of this document), to ensure that the requirements of the program are enforceable (see CAA section 110(a)(2)), and that the changes would not interfere with reasonable further progress or attainment of the NAAQS (see CAA section 110(l)).

In doing so, we relied on a number of guidance and policy documents including, but not limited to the 2006 Page/Oge Memorandum and the 2007 Page/Oge Memorandum (see footnote 7 of this document for the full references to these memoranda). Please see our October 3, 2011 proposed rule at page 61065 for a complete list of the guidance and policy documents upon which we relied.

Compliance With CAA Section 182(b)(3) Stage II Requirements

In our October 3, 2011 proposed rule, we concluded that the statutory provisions meet the CAA section 182(b)(3) stage II requirements for the following reasons:

• The State is requiring stage II vapor recovery controls in an area that encompasses all of the 1-hour ozone “serious” nonattainment area consistent with compliance schedules set forth in the Act and the State provides low-volume throughput exemptions that are consistent with those allowed for in CAA section 182(b)(3); and
• The State law exemption for a “gasoline dispensing site that is located on a manufacturer's proving ground” in ARS 41-2132(C) does not apply to any facility within the nonattainment area, and, assuming that the fuel throughput at the facility to which it had applied is representative of the throughput of any such facility that might locate within the nonattainment area, the exemption would be consistent with the low-volume throughput exemptions allowed for in CAA section 182(b)(3).

Further, in our October 3, 2011 proposed rule, we evaluated whether the exclusion of “E85” from the State law definition of gasoline comports with section 182(b)(3) vapor recovery requirements. Based on this evaluation, we concluded that, given how close the ORVR-equipped percentage for flexible fuel vehicles (FFVs) in the Phoenix metropolitan area (87 percent in 2008 and climbing) is to the ORVR widespread use threshold based on comparable VOC emissions (95 percent) and because the change in emissions due to use of E85 would not interfere with attainment and RFP of any of the NAAQS, ORVR is in widespread use in the FFV vehicle fleet in the Phoenix metropolitan area for the purposes of CAA section 202(a)(6). Based on the finding of “widespread use,” in our October 3, 2011 proposed rule, we proposed to waive the stage II vapor recovery requirements for E85 dispensing pumps in the Phoenix metropolitan area under section 202(a)(6).

Third, in our October 3, 2011 proposed rule, we noted that changes in ADWM's vapor recovery rules would generally serve to clarify and improve the existing stage II vapor recovery rules that we approved into the SIP in 1994, and that the only significant changes potentially affecting approvability with respect to CAA section 182(b) (3) would be the new exemptions for motor raceways, and for marine and aircraft refueling facilities. We evaluated the new exemptions and concluded that they would be acceptable under section 182(b)(3) because the fuel throughput at the one motor raceway facility to which the exemption applies is far below the 10,000-gallon per month low-throughput threshold exemption allowed under CAA section 182(b)(3) and because the exemptions as applied to the race cars themselves and to marine and aircraft refueling facilities do not apply to apply to “motor vehicles” as defined in CAA section 216(2) and thus are not required to be subject to stage II vapor recovery requirements under section 182(b)(3). Please see our October 3, 2011 proposed rule at pages 61066 and 61067 for more information about our evaluation of the submitted statutory provisions and rules for compliance with section 182(b)(3) and for more information about our proposed waiver under section 202(a)(6).

Compliance With CAA Section 110(l)

In our October 3, 2011 proposed rule, we also evaluated the statutory provisions and administrative rules submitted by ADEQ as part of the September 21, 2009 SIP revision under CAA section 110(l) for possible interference with any applicable requirement concerning reasonable further progress (RFP) and attainment of any of the NAAQS or any other applicable requirement under the Act. With respect to this SIP revision, we found that the only potentially significant adverse effect on emissions and, thus, potential for interference would stem from the exclusion of E85 from the definition of “gasoline” in ARS 41-2121. The exclusion of E85 from “gasoline” would allow for increased use of E85 (by FFVs) as a motor fuel in the Phoenix metropolitan area and would result in corresponding change in emissions from FFVs using E85 relative to the same vehicles using the specially formulated gasoline (referred to as “Arizona Cleaner Burning Gasoline,” or “Arizona CBG”) otherwise required. (Arizona CBG is a boutique fuel established to reduce vehicle emissions in the Phoenix metropolitan area and to help meet CAA air quality planning requirements.) The gasoline portion of E85 must continue to meet the specifications for Arizona CBG pursuant to AAC R20-2-718(B).

To evaluate the change in emissions, we reviewed a recently published study from the Journal of the Air & Waste Management Association titled “Effect of E85 on Tailpipe Emissions from Light-Duty Vehicles ” (herein, the “E85 Vehicle Emissions Study”), which compiled the results from previous published studies but also analyzed a significantly larger database compiled by EPA for vehicle certification purposes. As described in our October 3, 2011 proposed rule, though the results vary by pollutant and between “tier 1” (i.e., model year (MY) 1994-2003) and “tier 2” (MY 2004-2008) vehicles, in general, the study suggests that FFVs using E85 emit fewer oxides of nitrogen (NO_X), carbon monoxide, and particulate matter (PM) relative to the same FFVs using gasoline. However, with respect to VOCs, FFVs may well emit greater VOCs than the same FFVs using gasoline [based on the measurement results for non-methane organic gases (NMOGs)].

Thus, with respect to nitrogen dioxide, carbon monoxide and particulate matter, because emissions using E85 would be lower than those using CBG, we concluded that the incremental substitution of CBG with E85 would not interfere with RFP or attainment of the ambient standards for those pollutants.

We also concluded that the net effect on ozone conditions in the Phoenix 8-hour ozone nonattainment area would be beneficial despite the potential higher VOC emission rate by E85-fueled FFVs (relative to CBG-fueled FFVs) because of the offsetting effect of NO_X emissions reductions (from use of E85 relative to Arizona CBG) and because of the extension of stage II vapor recovery requirements to “Area A,” an area that is larger than the area formerly designated as nonattainment for the 1-hour ozone standard and that includes the fast-growing region west of the City of Phoenix.

On the basis of the above rationale, we determined in our October 3, 2011 proposed rule that this SIP revision, including the change in the definition of “gasoline” to exclude “E85,” would not interfere with RFP and attainment for any of the NAAQS. Please see our October 3, 2011 proposed rule at pages 61067 and 61068 for more information about our evaluation of the submitted statutory provisions and rules for compliance with section 110(l) of the CAA.

D. Proposed Correction of Previous Rulemaking

Lastly, in our October 3, 2011 proposed rule, we described our direct final action (59 FR 54521, November 1, 1994) to approve the administrative rules adopted by ADWM to provide for the installation and operation of stage II vapor recovery systems, and in which we included erroneous references and failed to identify the specific rules being incorporated by reference into the SIP. To address this issue, we proposed, under section 110(k)(6) and 301(a) of the CAA, to correct our previous codification of our approval of the stage II vapor recovery rules to identify the appropriate regulatory agency and to identify the specific rules that were being approved and incorporated by reference into the Arizona SIP. Please see our October 3, 2011 proposed rule at page 61068 for more information about our proposed error correction under CAA section 110(k)(6).

II. Public Comments and EPA Responses

Our October 3, 2011 proposed rule provided a 60-day comment period. During this period, we received no comments on our proposed action.

III. Final Action

As authorized in section 110(k)(3) of the Act and for the reasons provided in our October 3, 2011 proposed rule and summarized herein, EPA is taking final action to approve the statutory provisions and updated administrative rules establishing certain vapor recovery requirements in the Phoenix metropolitan area as a revision to the Arizona SIP. Specifically, we are taking final action to approve Arizona Revised Statutes (ARS) sections listed in table 1 of this document and the Arizona Administrative Code (AAC) sections listed in table 2 of this document. Second, as authorized under CAA section 202(a)(6), we are taking final action to waive the stage II vapor recovery requirements at E85 dispensing pumps in the Phoenix area under CAA section 202(a)(6) based on our conclusion that ORVR is in widespread use among the FFVs that use such facilities.

In so doing, we conclude that the submitted statutory provisions and updated administrative rules meet the related requirements for stage II vapor recovery under CAA section 182(b)(3) and will not interfere with attainment and RFP of any of the NAAQS or any other CAA applicable requirement, consistent with the requirements of CAA section 110(l). Final EPA approval of the updated statutory provisions and rules and incorporation of them into the Arizona SIP makes them federally enforceable.

Lastly, under section 110(k)(6) and 301(a) of the CAA, we are taking final action to correct and clarify the incorporation of the previous version of ADWM's vapor recovery related administrative rules into the Arizona SIP.

IV. Statutory and Executive Order Reviews

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, 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) given the limited nature of this SIP revision (as to geographic scope and vehicle applicability);
• 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 CAA; and
• Does not provide EPA with the discretionary authority to address disproportionate human health or environmental effects with practical, appropriate, 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. section 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. section 804(2).

Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by August 13, 2012. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements (See section 307(b)(2)).
