policies affecting future labeling of insect repellents. The ultimate goal of this activity is to help the consumer to effectively use the information on the label to select the insect repellent product most likely to meet their needs and readily understand label instructions regarding safe product use.

Responses to this collection of information are voluntary. One survey would be conducted over the life of this ICR. The collected information could be used to revise insect repellent product labels and to create other user friendly consumer information materials. By enabling consumers to make better choices in regard to purchasing and using products intended to protect their health, EPA will more effectively carry out its mandate to protect the public from unreasonable risks to human health.

Burden Statement: The annual public reporting and recordkeeping burden for this collection of information is estimated to average 15 minutes per response. Burden is defined in 5 CFR 1320.3(b).

Respondents/Affected Entities: members of the general public would participate in the survey.

Estimated Number of Potential Respondents: 3000.

Frequency of Response: One time. Estimated Total Annual Hour Burden: 750 hours.

Estimated Total Annual Cost: $15,675.

Changes in the Estimates: This is a new collection.

**Notice of Availability of the External Review Draft of the Guidance for**  **Applying Quantitative Data To Develop Data-Derived Extrapolation Factors for**  **Interspecies and Intraspecies Extrapolation** 

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

**ACTION :**  Notice of document availability for public comment.

**SUMMARY :**  The Environmental Protection Agency (EPA) is announcing a 45-day public comment period for the External Review Draft of ‘‘ Guidance for ApplyingQuantitative Data to Develop DataDerived Extrapolation Factors for Interspecies and Intraspecies Extrapolation. ’’ EPA is releasing this draft document solely for the purpose of seeking public comment prior to external peer review. The document will undergo independent peer review during an expert peer review meeting, which will be convened, organized, and conducted by an EPA contractor in 2011. The date of the external peer review meeting will be announced in a subsequent Federal Register notice. All comments received by the docket closing date July 25, 2011 will be shared with the external peer review panel for their consideration. Comments received after the close of the comment period may be considered by EPA when it finalizes the document. This document has not been formally disseminated by EPA. This draft guidance does not represent and should not be construed to represent EPA policy, viewpoint, or determination. Members of the public may obtain the draft interim guidance from http://www.regulations.gov; or http://www.epa.gov/raf/DDEF/ index.htm or from Dr. Michael Broder via the contact information below.

This draft Guidance for Data Derived Extrapolation Factors document outlines approaches for developing factors for inter- and intra-species extrapolation based on data describing toxicokinetic and/or toxicodynamic properties of particular agent(s). The draft document was developed to provide guidance for EPA staff in evaluating such data and/or information and to provide information to the regulated community and other interested parties about deriving and implementing extrapolation factors derived from data instead of defaults.

**DATES :**  All comments received by the docket closing date July 25, 2011 will be shared with the external peer review panel for their consideration. Comments received beyond that time may be considered by EPA when it finalizes the document.

If you send an e-mail comment directly to EPA, without going through http:// www.regulations.gov, your e-mail address will be automatically captured and included as part of the comment that is placed in the public docket and made available on the Internet. If you submit an electronic comment, EPA recommends that you include your name and other contact information in the body of your comment and with any disk or CD–ROM you submit. If EPA cannot read your comment due to technical difficulties and cannot contact you for clarification, EPA may not be able to consider your comment.

. **SUPPLEMENTARY INFORMATION :**  Key goals for the U.S. EPA include improving the transparency, objectivity and scientific basis for health risk assessment. In 2005, a WHO-sponsored effort produced guidance on the development of Chemical-Specific Adjustment Factors (CSAFs). CSAFs are intended to replace default uncertainty factor values for inter- and intraspecies extrapolation in health risk assessment. The U.S. EPA recognizes differences between the WHO guidance and typical Agency risk assessment practices, policies and guidance. EPA’s Risk Assessment Forum convened a technical panel that initiated work on developing draft guidance for use in replacing default values for inter- and intraspecies uncertainty factors with science-based extrapolation factors. The draft document has been reviewed by EPA’s Risk Assessment Forum and Science and Technology Policy Council and approved for external review. In 2010, the document was sent to the National Science and Technology Council (NSTC) Committee on Environment and Natural Resources, Toxics and Risk Subcommittee for informal review and comment. The draft document is now available for public comment.

The draft document has been structured and developed in accordance with existing Agency policies on health risk assessment. The draft document provides guidance for the evaluation of data describing interspecies differences in chemical disposition (toxicokinetics);interspecies differences in toxicantinduced response (toxicodynamics); intraspecies differences in chemical disposition (toxicokinetics); andintraspecies differences in toxicantinduced response (toxicodynamics). The document maintains the subdivision of the interspecies and intraspecies uncertainty factors into toxicokinetic and toxicodynamic components specified in the U.S. EPA Inhalation Reference Concentration methodology (U.S. EPA, 1994). EPA will consider all peer review and public comments in finalizing Guidance for ApplyingQuantitative Data to Develop DataDerived Extrapolation Factors for Interspecies and Intraspecies Extrapolation.

**Modification of the Expiration Date for the National Pollutant Discharge**  **Elimination System General Permit for Stormwater Discharges From**  **Construction Activities on Tribal Lands Within the Southeastern United States** 

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

**ACTION :**  Notice.

**SUMMARY :**  EPA Region 4 proposes to modify the expiration date of the National Pollutant Discharge Elimination System (NPDES) general permit authorizing the discharge of stormwater from construction activities on Tribal Lands within the states of Alabama, Florida, Mississippi and North Carolina. This NPDES construction general permit (CGP), hereinafter referred to as ‘‘the Region 4 CGP,’’ was issued on September 1, 2009, with an expiration date of August 31, 2011. EPA Region 4 is proposing to extend the expiration date from August 31, 2011, to September 1, 2012. No other revisions are being proposed to the Region 4 CGP. The purpose of extending the expiration date is to ensure that there is no lapse in permit coverage prior to the effective date of the issuance of a new permit, which has been proposed for public review and comment in a separate action. Information about the proposed new permit, hereinafter referred to as ‘‘the new National CGP,’’ can be found at http://cfpub.epa.gov/npdes/stormwater/ cgp.cfm.

**DATES :**  EPA is proposing a modification to the Region 4 CGP that would extend the expiration date from August 31, 2011, to September 1, 2012. If the proposed modification is finalized, the Region 4 CGP would expire at midnight, on September 1, 2012, or on the effective date of the new National CGP, whichever is earlier. Comments on the proposal to modify the expiration date of the Region 4 CGP must be postmarked by July 11, 2011.
