subsequently added or replaced, manufacturer approval of the overall component is not sufficient to demonstrate compatibility.
Options for Meeting the Compatibility Requirement

Acceptable methods for owners and operators of UST systems storing ethanol-blended fuels greater than 10 percent ethanol or biodiesel-blended fuels greater than 20 percent biodiesel to demonstrate compatibility under 40
CFR 280.32 are:

• Use components that are certified or listed by a nationally recognized, independent testing laboratory (for example, Underwriters Laboratories) for use with the fuel stored;

• Use components approved by the manufacturer to be compatible with the fuel stored. EPA considers acceptable forms of manufacturer approvals to:

Æ Be in writing;

Æ Indicate an affirmative statement of compatibility;

Æ Specify the range of biofuel blends the component is compatible with; and

Æ Be from the equipment manufacturer, not another entity (such as the installer or distributor); or

• Use another method determined by the implementing agency to sufficiently protect human health and the environment. EPA will work with states as they evaluate other acceptable methods.

Currently, a note in 40 CFR 280.32 allows owners and operators to use the American Petroleum Institute’s (API) Recommended Practice 1626, an industry code of practice, to meet thecompatibility requirement for ethanolblended fuels. The original version of API 1626 (1st ed. 1985, reaffirmed in 2000) applies to up to 10 percent ethanol blended with gasoline and is not applicable to meet the compatibility requirement for ethanol blends greater than 10 percent. In August 2010, API published a second edition of API 1626. The second edition addresses ethanol blends greater than 10 percent and may be used to demonstrate compatibility for UST systems storing ethanol blends.

If the UST owner and operator is not able to demonstrate that the UST system is made of materials that are compatible with the ethanol blend or biodiesel blend stored, according to 40 CFR 280.32, the UST owner and operator may not use the system to store those fuels.

State UST program regulations may be more stringent than the Federal UST regulations. In addition to state and Federal UST requirements, UST system owners and operators may be subject to other Federal, state, or local regulatory requirements (for example, U.S. Occupational Safety and Health Administration, National Fire Prevention Association, and International Fire Code). UST system owners and operators should check with their state and local agencies to determine other requirements.

**Science Advisory Board Staff Office; Notification of a Public Teleconference**  **of the SAB Mercury Review Panel**

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Notice.

**SUMMARY :**  The Environmental Protection Agency (EPA or Agency) Science Advisory Board (SAB) Staff Office announces a public teleconference of the Mercury Review Panel.

**DATES :**  The teleconference will be held on July 20, 2011, from 1 to 4 p.m. (Eastern Daylight Time)

**ADDRESSES :**  The public teleconference will be conducted by telephone only.

**FOR FURTHER INFORMATION CONTACT :**  Members of the public who wish to obtain further information regarding this meeting must contact Dr. Angela Nugent, Designated Federal Officer (DFO). Dr. Nugent may be contacted at the EPA Science Advisory Board (1400R), U.S. Environmental Protection Agency, 1200 Pennsylvania Avenue, NW., Washington, DC 20460; or by telephone/voice mail at (202) 564–2218; fax at (202) 565–2098; or e-mail at nugent.angela@epa.gov. General information concerning the SAB can be found at the EPA SAB Web site at http://www.epa.gov/sab.

**SUPPLEMENTARY INFORMATION :** 

Background: The SAB was established pursuant to the Environmental Research, Development, and Demonstration Authorization Act (ERDAA), codified at 42 U.S.C. 4365, to provide independent scientific and technical advice to the EPA Administrator on the technical basis for Agency positions and regulations. The SAB is a Federal Advisory Committee chartered under the Federal Advisory Committee Act (FACA), 5 U.S.C., App. 2. Pursuant to FACA and EPA policy, notice is hereby given that the SAB Mercury Review Panel will hold a public teleconference to discuss a draft advisory report Review of EPA’s Draft Technical Support Document: NationalScale Mercury Risk Assessment Supporting the Appropriate andNecessary Finding for Coal and OilFired Electric Generating Units—March

2011. The Panel will comply with the provisions of FACA and all appropriate SAB Staff Office procedural policies.

EPA is considering regulating the emissions of hazardous air pollutants (HAPs) released from coal-burning electric generating units in the United States (U.S. EGUs) under Section 112(n)(1)(A) of the Clean Air Act (CAA). EPA developed a draft risk assessment for mercury, entitled Technical Support Document: National-scale Mercury Risk
Assessment. This draft assessment considers the nature and magnitude of the potential risk to public health posed by current U.S. EGU mercury emissions and the nature and magnitude of the potential risk posed by U.S. EGU mercury emissions in the future, once all anticipated CAA-related regulations potentially reducing mercury from U.S. EGUs are in-place. EPA’s Office of Air and Radiation requested peer review of this draft document. To conduct this review, the SAB Mercury Review Panel met on June 15–17, 2011 (76 FR 29746– 29747) to review the draft Technical Support Document. The purpose of the July 21 2011, teleconference is to discuss the panel’s draft report, Review of EPA’s Draft Technical Support Document: National-Scale Mercury Risk Assessment Supporting the Appropriateand Necessary Finding for Coal and OilFired Electric Generating Units—March

2011.

Availability of Meeting Materials: The agenda, the draft panel report, and other meeting materials will be available on the SAB Web site at http:// yosemite.epa.gov/sab/sabproduct.nsf/ fedrgstr

Procedures for Providing Public Input: Public comment for consideration by EPA’s Federal advisory committees and panels has a different purpose from public comment provided to EPA program offices. Therefore, the process for submitting comments to a Federal advisory committee is different from the process used to submit comments to an EPA program office.

Federal advisory committees and panels, including scientific advisory committees, provide independent advice to EPA. Members of the public can submit comments for a Federal advisory committee to consider as it develops advice for EPA. Input from the public to the SAB will have the most impact if it provides specific scientific
