**SUPPLEMENTARY INFORMATION :** 
Statutory Background

Section 211(f)(1) of the Act makes it unlawful for any manufacturer of any
fuel or fuel additive to first introduce into commerce, or to increase the concentration in use of, any fuel or fuel additive for use by any person in motor vehicles manufactured after model year 1974 which is not substantially similar to any fuel or fuel additive utilized in the certification of any model year 1975, or subsequent model year, vehicle or engine under section 206 of the Act. EPA last issued an interpretive rule on the phrase ‘‘substantially similar’’ at 73 FR 22281 (April 25, 2008).

Section 211(f)(4) of the Act provides that upon application by any fuel or fuel additive manufacturer, the Administrator may waive the prohibitions of section 211(f)(1) if the
Administrator determines that the applicant has established that such fuel or fuel additive or a specified concentration thereof, and the emission products of such fuel or fuel additive or a specified concentration thereof, will
not cause or contribute to a failure of any emission control device or system (over the useful life of the motor vehicle, motor vehicle engine, nonroad engine or nonroad vehicle in which such device or system is used) to achieve compliance by the vehicle or engine with the emission standards to which it has been certified pursuant to sections 206 and 213(a) of the Act. In other words, the Administrator may grant a waiver for a prohibited fuel or fuel additive if the applicant can
demonstrate that the new fuel or fuel
additive will not cause or contribute to engines, vehicles or equipment failing to
meet their emissions standards over their useful life. The statute requires
that the Administrator shall take final action to grant or deny the application, after public notice and comment, within 270 days of receipt of the application.

The current statute reflects changes made under the Energy Independence and Security Act of 2007 which explicitly extended the section 211(f)(4) waiver provision to nonroad engines and nonroad vehicles, extended the period allowed for consideration of the waiver application from 180 days to 270 days and deleted a provision that resulted in a waiver becoming effective by operation of law if the Administrator made no decision within 180 days. The 1978 waiver for 10 percent ethanol in gasoline (‘‘E10’’) became effective under the previous provision when no decision was made by the Administrator


### 18229 Federal Register / Vol. 74, No. 75 / Tuesday, April 21, 2009 / Notices

regarding the waiver application and the waiver became effective by operation of law after passage of 180 days.

Context of Growth Energy’s Waiver Application

On March 6, 2009, Growth Energy and
54 ethanol manufacturers submitted a waiver application to the Administrator, pursuant to section 211(f)(4) of the Act, for ethanol-gasoline blends containing up to 15 percent ethanol by volume (‘‘E15’’).

Growth Energy maintains that under the renewable fuel program requirements of the Energy Independence and Security Act of 2007, which is now primarily satisfied by the use of ethanol in motor vehicle gasoline,
there exists a ‘‘blend barrier’’ or ‘‘blendwall’’ by which motor vehicle gasoline in the U.S. essentially will
become saturated with ethanol at the 10 volume percent level very soon. Growth Energy maintains that a necessary first step is to increase the allowable amount of ethanol in motor vehicle gasoline up to 15 percent (E15) in order to delay the blendwall. They also claim other ways of delaying the blendwall could include adding more stations offering E85 blends and bringing in the renewable fuel mandate specified in the Energy Independence and Security Act of 2007. For its part, Growth Energy claims that
the ‘‘blendwall’’ will make those
renewable fuel mandates unreachable
and that there are substantial
environmental benefits associated with higher ethanol blends.

Growth Energy states in its waiver application that its supporting studies and extensive experience with ethanol support a conclusion that E15 will not
cause or contribute to the failure of an emission control system such that the engine or vehicles fails to achieve compliance with its emission standards.
In addition to the information that Growth Energy submitted, EPA is aware that several interested parties are investigating the impact that mid-level blends ( e.g., E15 or E20) may have on vehicles and equipment. These testing programs are evaluating emissions impacts as well as other types of impacts (i.e. , catalyst, engine, and fuel system durability, and onboard diagnostics) on vehicles and equipment. The Department of Energy, working in conjunction with the Coordinating
Research Council and other interested parties, is leading a substantial testing effort. Results from this program to date are referenced in Growth Energy’s waiver request, and we expect
additional data will be added to the
docket as it becomes available. One potential outcome at the end of our process, after reviewing the entire body of scientific and technical information available to us, may be an indication that a fuel up to E15 could
meet the criteria for a waiver for some vehicles and engines but not for others. Some vehicles and engines may be more susceptible to emission increases or durability problems that cause or contribute to these vehicles or engines failing to meet their emissions standards. Assuming the criteria are met for a certain subset of vehicles, one interpretation of section 211(f)(4) is that the waiver could be approved in part for only that subset of vehicles or engines for which testing supports its use and for which adequate conditions or other measures could be implemented to ensure its proper use.

Another potential outcome is a
conclusion that ethanol blends of greater than 10 percent, but less than 15 percent, warrant a waiver. To take such action, the Agency would need similar evidence, such as emissions durability testing, as what would be needed to address a waiver for a 15 percent blend.

Any approval, either fully or partially, is likely to elicit a market response to
add E15 blends to E10 and E0 blends in the marketplace, rather than replace them. Thus consumers would merely
have an additional choice of fuel.

Experience in past fuel programs has
shown that even with consumer education and fuel implementation efforts, there sometimes continues to be public concern for new fuel requirements. Several examples include the phasedown of the amount of lead allowed in gasoline in the 1980s and the introduction of reformulated gasoline (RFG) in 1995. Some segments of the public were convinced that the new fuels caused vehicle problems or decreases in fuel economy. Although substantial test data proved otherwise, these concerns lingered in some cases for several years. As a direct result of these experiences, EPA wants to be assured that prior to granting a waiver, sufficient testing has been conducted to demonstrate the compatibility of a waiver fuel with engine, fuel and emission control system components.

EPA has previously granted waivers with certain restrictions or conditions, including requirements that precautions be taken to prevent using the waiver fuel as a base fuel for adding oxygenates, that certain corrosion inhibitors be utilized when producing the waiver fuel, and that waiver fuels meet voluntary consensus-based standards such as those developed by the American Society for Testing and Materials (ASTM). In a partial waiver for fueling certain types of vehicles or engines, the condition placed on the
fuel manufacturer would be that the fuel is only used in certain vehicles or engines (i.e. , E15 is only used in the subset of vehicles or engines identified in the partial or conditional waiver). EPA recognizes that there may be legal and practical limitations on what a fuel manufacturer may be required or able to do to ensure compliance with the conditions of the waiver, including preventing misfueling. EPA has not previously imposed this type of
‘‘downstream’’ condition on the fuel
manufacturer as a condition for obtaining a section 211(f)(4) waiver. EPA does, however, have experience with compliance problems occurring when two types of gasoline have been available at service stations. Beginning
in the mid-1970s with the introduction of unleaded gasoline and continuing into the 1980s as leaded gasoline was phased out, there was significant intentional misfueling by consumers. At
the time most service stations had pumps dispensing both leaded and unleaded gasoline and a price differential as small as a few cents per gallon was enough to cause some
consumers to misfuel.

Request for Comments

EPA invites public comments and data on all aspects of the waiver application that will assist the Administrator in determining whether the statutory basis for granting the waiver request for ethanol-gasoline blends containing up to E15 has been met. EPA specifically requests comment
and data that will enable EPA to:

(a) evaluate whether an appropriate
level of scientific and technical
information exists in order for the
Administrator to determine whether the
use of E15 will not cause or contribute to a failure of any emission control device or system over the useful life of any motor vehicle or motor vehicle engine (certified pursuant to section 206 of the Act) to achieve compliance with applicable emission standards;

(b) evaluate whether an appropriate
level of scientific and technical
information exists in order for the
Administrator to determine whether the
use of E15 will not cause or contribute to a failure of any emission control device or system over the useful life of any nonroad vehicle or nonroad engine (certified pursuant to sections 206 and 213(a) of the Act) to achieve compliance with applicable emission standards; and,

(c) evaluate whether an appropriate
level of scientific and technical
information exists in order for the


### 18230 Federal Register / Vol. 74, No. 75 / Tuesday, April 21, 2009 / Notices

Administrator to grant a waiver for an ethanol-gasoline blend greater than 10 percent and less than or equal to 15 percent by volume.

EPA also requests comment on: (d) all legal and technical aspects regarding the possibility that a waiver might be granted, in a conditional or partial manner, such that the use of up
to E15 would be restricted to a subset of gasoline vehicles or engines that would be covered by the waiver, while other vehicles or engines would continue using fuels with blends no greater than E10. EPA seeks comment
on what measures would be needed to ensure that the fuel covered by the waiver (i.e. a partial or conditional waiver) is only used in that subset of vehicles or engines. EPA acknowledges that the issue of misfueling would be challenging in a situation where a conditional waiver is granted. To the extent a partial or conditional waiver may be appropriate, please provide comments on the legal and technical
need for restrictions of this nature. Comments are also requested on how the Agency might define a partial or conditional waiver. For example, assuming there is sufficient technical basis, should the subset of vehicles or engines that is allowed to use the waived fuel be defined by model year of production, engine size, application ( e.g., highway vehicle vs. nonroad engine), or some other defining
characteristic.

(e) Any education efforts that would be needed to inform the public about
the new fuel that would be available if a waiver is granted. To address the possibility of a grant of a conditional or partial waiver, the Agency requests specific comments on public education
measures that would be needed if the waiver allowed the fuel to be used only in a subset of existing vehicles or engines.

Commenters should include data or specific examples in support of their
comments in order to aid the Administrator in determining whether to grant or deny the waiver request. In order for any testing programs evaluating emissions impacts, as well as other types of impacts (i.e. , catalyst, engine, fuel system durability, or onboard diagnostics), to be useful in EPA’s evaluation of Growth Energy’s waiver application, any mid-level ethanol blend testing or other analyses should consider such impacts across a range of engines and equipment (including the fuel systems) that are currently in service and that could be exposed to mid-level ethanol blends. Such testing and analyses should also assess the long-term impacts of such blends. EPA specifically solicits the data and results from such testing and analyses.

Although it is not a specific criterion by which to evaluate a waiver request under section 211(f), any approved waiver could require program changes
to accommodate this new fuel. EPA
seeks comment on the effect of a potential waiver for ethanol blends above 10 percent and up to 15 percent on existing fuel programs ( e.g., gasoline detergent certification, protection of underground storage tanks, etc.) and on the gasoline production, distribution and marketing infrastructure. For example, would EPA need to modify its RFG and anti-dumping regulations to account for a higher blend? EPA also seeks comment on the dynamics of the blendwall concern raised by Growth Energy, the extent to which the use of an E15 blend would in practice help address this concern, and what additional steps would have to be taken to bring E15 to market should a waiver be granted.

**SUPPLEMENTARY INFORMATION :** 

Background: The Clean Air Scientific Advisory Committee (CASAC) was established under section 109(d)(2) of the Clean Air Act (CAA or Act) (42 U.S.C. 7409) as an independent scientific advisory committee. CASAC provides advice, information and
recommendations on the scientific and technical aspects of air quality criteria and national ambient air quality standards (NAAQS) under sections 108
and 109 of the Act. The CASAC is a Federal advisory committee chartered under the Federal Advisory Committee Act (FACA), as amended, 5 U.S.C., App. The CASAC will comply with the provisions of FACA and all appropriate SAB Staff Office procedures.

Section 109(d)(1) of the CAA requires that the Agency periodically review and revise, as appropriate, the air quality criteria and the NAAQS for the six ‘‘criteria’’ air pollutants, including particulate matter (PM). EPA conducts
scientific assessments to determine both primary (health-based) and secondary (welfare-based) standards for each of these pollutants.

The CASAC PM Review Panel will hold a public teleconference on May 7, 2009 to review and approve draft letters reviewing three EPA draft documents supporting EPA’s review of the PM National Ambient Air Quality Standard: (1) Integrated Science Assessment for
Particulate Matter—First External Review Draft, Dec 2008; (2) PM NAAQS: Scope and Methods Plan for Health Risk and Exposure Assessment (February 2009); and (3) PM NAAQS: Scope and Methods Plan for Urban Visibility Impact Assessment (February 2009).

The CASAC PM Panel previously held a public meeting on April 1–2, 2009 (announced in 74 FR 7688–7689) to review these documents. The purpose of the May 7, 2009 teleconference is to
