**SUPPLEMENTARY INFORMATION :** 
I. General Information A. Does this action apply to me?

This action is directed to the public in general. As such, the Agency has not attempted to describe the specific entities that this action may apply to. Although others may be affected, this action applies directly to the submitter of the PMNs addressed in this action. B. What should I consider as I prepare my comments for EPA?

1. Submitting CBI. Do not submit this information to EPA through regulations.gov or email. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD–ROM that you mail to EPA, mark the outside of the disk or CD–ROM as CBI and then identify electronically within the disk or CD–ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2.

2. Tips for preparing your comments. When submitting comments, remember
to:


### 17657 Federal Register / Vol. 78, No. 56 / Friday, March 22, 2013 / Notices

i. Identify the document by docket ID number and other identifying information (subject heading, Federal Register date and page number).

ii. Follow directions. The Agency may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number.

iii. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.

iv. Describe any assumptions and provide any technical information and/ or data that you used.

v. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.

vi. Provide specific examples to illustrate your concerns and suggest alternatives.

vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.

viii. Make sure to submit your comments by the comment period deadline identified. II. Why is EPA taking this action?

EPA classifies a chemical substance as either an ‘‘existing’’ chemical or a ‘‘new’’ chemical. Any chemical substance that is not on EPA’s TSCA Inventory is classified as a ‘‘new chemical,’’ while those that are on the TSCA Inventory are classified as an ‘‘existing chemical.’’ For more information about the TSCA Inventory go to: http://www.epa.gov/opptintr/ newchems/pubs/inventory.htm. Anyone who plans to manufacture or import anew chemical substance for a nonexempt commercial purpose is required by TSCA section 5 to provide EPA with a PMN, before initiating the activity. Section 5(h)(1) of TSCA authorizes EPA to allow persons, upon application, to manufacture (includes import) or process a new chemical substance, or a chemical substance subject to a significant new use rule (SNUR) issued under TSCA section 5(a), for ‘‘test marketing’’ purposes, which is referred to as a test marketing exemption, or TME. For more information about the requirements applicable to a new chemical go to: http://www.epa.gov/ oppt/newchems. Under TSCA sections 5(d)(2) and 5(d)(3), EPA is required to publish in the Federal Register a notice of receipt of a PMN or an application for a TME and to publish in the Federal Register periodic status reports on the new chemicals under review and the receipt of NOCs to manufacture those chemicals. This status report, which covers the period from January 14, 2013 to February 8, 2013, consists of the PMNs and TMEs, both pending or expired, and the NOCs to manufacture a new chemical that the Agency has received under TSCA section 5 during this time period. III. Receipt and Status Reports

In Table I. of this unit, EPA provides the following information (to the extent that such information is not claimed as CBI) on the PMNs received by EPA during this period: The EPA case number assigned to the PMN, the date the PMN was received by EPA, the projected end date for EPA’s review of the PMN, the submitting manufacturer/ importer, the potential uses identified by the manufacturer/importer in the PMN, and the chemical identity.

1 The tailpipe GHG emissions used for compliance with the CO 2 standards described in 40 CFR 86.1818 are the carbon-containing emissions (generally, CO 2 , hydrocarbons, and carbon monoxide), which are summed based on the carbon weight fraction of each component into a value described in the regulations as the ‘‘carbon-related exhaust emissions’’ (CREE). For simplicity, however, in this notice we are using the term CO 2 instead of CREE, as CO 2 is more broadly understood and makes up the vast majority of the total carbon emissions from vehicles. Dated: March 4, 2013. Chandler Sirmons, Acting Director, Information Management Division, Office of Pollution Prevention and Toxics.

**SUPPLEMENTARY INFORMATION :**  I. Background

Under EPA’s greenhouse gas (GHG) program for passenger automobiles and light trucks, starting with the 2016 model year, the regulations describe two pathways for determining the GHG value for flexible fuel vehicles (FFVs) that run either on gasoline or on E85 (a fuel mixture of 85 percent ethanol and 15 percent gasoline). The default approach is to use the GHG emissions of the vehicle operated solely on gasoline (see 40 CFR 600.510–12). The alternative is to combine the gasoline and E85 GHG values together in a way that accounts for real-world use of E85 by using a weighting factor. 1 When the weighting factor is used, the emissions value used for the vehicle model in the fleet average calculations would be determined by weighting the gasoline and E85 values of the model together using the specified factor (see 40 CFR 600.510–12(k)).

EPA’s regulations establish two different approaches that may be used to determine the value of the weighting factor. Manufacturers may request that EPA determine and publish by guidance an appropriate value for the E85 weighting factor based on EPA’s assessment of the real-world use of E85. Alternatively, a manufacturer may
